Chapter Text

Outside New York, in the middle of the night, there is a rather large warehouse that, at first glimpse, seems abandoned. However, the fact that there are five men at the gate with alien-looking blasters in their hands may suggest otherwise. Known to only a few, however, these were not human, but Kraang droids wearing human disguises. They kept vigilance over everything in front of them, but even though they solely focused on what was in front of them, they failed to notice four shady figures quickly zip past them and up the wall surrounding the compound.

Once on the other side of the wall, one would see dozens of guards circling the inner perimeter, more Kraang droids. This time with no disguises, one could see their mechanical bodies and the pink, brain-like creatures inside the chests. The four figures were careful to avoid detection. They zipped in between cover spots: behind a box, in a barrel, any place that could hide them from the Kraang droids site was used, and the four entered the building through an open window.

Though the outside looked normal, inside, one could see it as a Kraang base due to all the alien surroundings. Then the four figures enter as Leonardo, Donatello, Michelangelo, and Raphael: the Teenage Mutant Ninja Turtles.

"Alright, here's the plan," Leo relayed to his brothers, "We find out what the Kraang are up to, stop them, and get out."

"I like that plan," Raph responded, "It's easy to remember. Not like Donnie going on about one of his lame inventions."

"I'll have you know Raph, which my stuff has helped save all of our shells, and the city, countless times," Donnie glared back.

"Wouldn't it still be easier to just give the basics and not run down every minor detail?" Raph argued.

"Raph's gotcha, D,'" Mikey agreed, "We don't need to hear you speak Spanish all the time." 

Donnie was about to reply before Leo interrupted, "That's enough. Guys, remember the plan."

The Turtles quickly made their way deeper and deeper into the Kraang base and were careful to avoid any detection. They eventually made their way to a large chamber and stuck to the ceiling beams to keep their cover when they looked into the chamber and saw a very familiar-looking device.

"Umm... guys, call me crazy, but doesn't that look like the same portal we saw back at TCRI?" Raph asked.

He was right. It looked exactly like the portal from TCRI. Even worse, there were at least five dozen Kraang droids guarding it, with five or six working on the portal. One Kraang, the one that appeared to be in charge, walked up to another one and began to speak in its monotone voice.

"Kraang, we are receiving that which is known as a transmission from the one known as our partner who works with Kraang."

The other Kraang droid replied in the same tone, "Open the transmission that has been transmitted by the one that works with Kraang that is known as our partner."

The Turtles caught wind of the conversation. 

"Partner?" Donnie asked. 

"Who in the right mind would be working with them?!" he whispered.

A Kraang droid walked to a counsel and began typing away and a hologram appeared revealing the Kraang's partner, and the Turtles' mortal nemesis. 

"Greetings, one known as Shredder," the Kraang droid greeted.

Each of the Turtles' gasped. 

"That's right," Leo remembered, "Shredder's been working with the Kraang since the Technodrome."

"There hasn't been much activity between the Foot and the Kraang since then, I guess we just forgot the alliance," Donnie assumed.

"And if they started talking again, that means this has gotta be big," Raph suggested.

"Something big and bad," Mikey agreed.

"Is the portal completed yet?"  Shredder asked from the hologram.

"That which is known as the portal has yet to reach the state that is known as the state of its completion," a Kraang droid replied.

"My patience is wearing thin,"  Shredder warned,  "The Turtles' have decimated nearly all of our combined forces, and my new Foot drones are taking longer to complete than expected. If we do not act quickly and gather more of your soldiers, our enemies will strike and end us."

"Understood. We will accelerate the efforts that need acceleration," the Kraang droid complied.

"Do not fail me. Or else the consequences will be unpleasant."

 With that, the hologram cut off.

"Welp, we know their plan," Raph announced as he drew his sai, "Time to smash these bots!"

"For once Raph, I agree," Leo stated.

Leo drew his katana blades and the brothers jumped down and engaged the enemy in a surprise attack. 

As they jumped, Mikey shouted, "BOOYAKASHA!"

Despite the vast numbers they possessed, the Kraang were unprepared for an assault from the Turtles. Leo sliced every Kraang droid that approached him and was quick to avoid any blaster fire they shot at him. Mikey used his nunchucks to bash anything that moved. Raph impaled all the bots in his sight with his sai and tore the drones apart with them as well. Donnie was able to bat any droid that he came close to with his bo staff. The Kraang droids were always easy to take down. After five minutes of fighting, the Turtles came out in victory.

"Okay, bad guys are toast. Now what?" Mikey asked. 

As he asked that, Donnie approached a large box one of the droids was carrying to the portal. As Donnie opened it, he was shocked at what he saw.

"What is it, Donnie?" Leo asked. 

The object looked exactly like the power cell Leatherhead had given them that powered the TCRI portal, only it was glowing blue, not pink.

"I remember this," Donnie stated, "I downloaded specs for the portal from the Kraang orb a while ago, it showed that a blue power cell was some sort of dimensional inducer."

"Meaning?" Raph asked because he was no scientist.

Donnie sighed as he translated, "This is what lets the Kraang travel between Dimension X and our universe."

"So what do we do?" Leo asked.

"When in doubt, break it," Raph stated.

Raph drew his sai ready to impale the device, but Donnie pulled it away before the sai made contact.

"You know what your problem is Raph? You never think with your head," Donnie criticized, earning a glare from Raph.

"C'mon. What's the worst that could happen?" Mikey asked in a slacker-like tone.

"It could create a black hole that could implode the ENTIRE UNIVERSE, Mikey!" Donnie shouted.

Alarms soon activated all over the facility, alerting every Kraang in the compound.

"Time to go!" Leo announced. 

His brothers couldn't agree with him more as they left the chamber carrying their new precious cargo. Leo, Raph, and Mikey knocked away any Kraang droid that came their way as they tried to fight their way out of the enemy base. Donnie couldn't fight because he held the dimensional inducer and did not want to risk damaging it. 

The Turtles soon made their way outside and arrived at their trademark vehicle: the Shellraiser. Each of them entered their respective stations: Leo was the driver, Raph was in charge of weapons, Mikey had navigation, and Donnie took the computer systems still holding the inducer. 

Leo put the petal to the metal as he floored it. However, the Kraang were quick to mobilize as dozens of vans came pouring out of the facility in close pursuit.

"Keep driving Leo! I got these losers!" Raph announced as he shot manhole covers from the gun on the back. He was able to knock a few out of the road.

One van, however, had its roof poop open and a large cannon-like device appeared. It got a lock on the Shellraiser and fired. A purple energy beam shot out and directly hit the Shellraiser. The impact knocked the Turtles out of their seats, except Leo who was buckled to the driver's seat struggling hard to shake their pursuers. The inducer was knocked out of Donnie's hands and landed on the floor, no damage came to it, fortunately.

"What the heck was that?!" Leo shouted.

That would be the least of their worries though. As the beam hit the Shellraiser, purple electricity began to surge everywhere inside. One bolt hit the inducer, causing it to glow bright blue and hum. The blue light from the inducer began to circle the whole vehicle before a blue aura formed on the outside. 

As the hum grew louder, Donnie noticed and got a worrying feeling. 

"Uh, oh."

Soon the Shellraiser was engulfed in a bright flash of light and surged forward at incredible speed. The vans all behind stopped. The next thing the Kraang saw was tire tracks on fire.

From the outside, it appeared that the Shellraiser was traveling through a large vortex. Blue and pink beams of light shot right passed at high speeds. The Turtles wouldn't notice as they were too busy screaming their lungs out. The momentum had pushed Mikey, Raph, and Donnie to the back wall and Leo to the seat he was still buckled into. When Raph felt like he was going to get flatter than a pancake, he decided it was enough. 

"LEO! HIT THE BRAKES! HIT THE BRAKES!" he shouted.

Leo complied and slammed his foot hard on the brakes. The Shellraiser stopped, and the Turtles were all flung to the front and slammed face-first into the wall, minus the buckled driver. 

The door opened, and the turtles all stepped out, however, with one step, they all fell face-flat into the ground. They had expected to hit the concrete, but to their surprise, they hit snow. They soon got up but were still a little wobbly.

"Where the heck are we?" Raph asked.

"I have no idea," Mikey answered.

It was morning. The sun was up, there were evergreens all around them, and snow was everywhere.

Donnie took out his T-Phone, hoping to use his GPS, but he did not expect the result. 

"There's no signal," he stated, "Maybe the phone is damaged."

Mikey noticed something else in the environment, "Dudes, smoke!" 

Smoke is coming from a small cottage in the far distance. The other brothers saw it. 

"Well, maybe they know where we are," he mused.

 Before he could head over, Leo stopped him.

"Hold on Mikey. We can't just walk in. The last thing we want is to give someone a heart attack," he stated, for he knew that giant, talking turtles were not a common sight.

"Then what do you propose we do, 'Fearless Leader'?" Raph criticized.

Leo tried to think of something, and an idea came to mind.

He came to the cottage, wearing a dark blue robe and hood that the Shellraiser had stored. He came up to a sign and read it. 

"Eh, 'Wandering Oaken's Trading Post and Sauna' doesn't sound too bad."

The disguised turtle then entered and took notice of a rather large man behind a counter. 

"Big Summer Blowout!" the man announced in a Norwegian accent, unaware that he was talking to a humanoid turtle, "Half-off swimming suits, clogs, and a sunblock of my invention, ya?" 

"Umm... no. Thank you," Leo replied, "Do you know where the closest populated area is?"

"Nearest place is Arendelle. South down the mountain."

"Thanks, that's all I needed," Leo thanked before he left.

"Hmm...what a strange fellow," the post owner mused.

Leo returned to his brothers waiting by the Shellraiser. 

"Well?" Raph asked.

"There's a place called Arendelle south from here. We can probably find some more info there," Leo stated.

"Sounds like a plan," Mikey agreed.

"Sure, whatever," Raph said.

"Hold on one sec," Donnie said before returning to the Shellraiser. 

A few seconds later, the vehicle turned invisible, much to the three's shock. Donnie stepped out. 

"I swiped it from a Kraang ship. This way, it'll stay out of sight, and the inducer will be safe."

"Good work Donnie," Leo congratulated, "Okay guys, let's move. Next stop, Arendelle."

Chapter Text

The Turtles arrived near Arendelle. 

To avoid starting a panic, each of them sported a robe and hood: Leo's was dark blue, Donnie's a dark purple, Raph wore a dark red one, and Mikey had one that was dark orange. They took a quick note of the surroundings before venturing further into the kingdom.

"So, this is Arendelle," Leo observed.

"Seems like a nice place," Donnie stated.

"As long as they have pizza, I'm good," Mikey beamed, to which his brothers rolled their eyes.

"Why are we here again?" Raph asked.

"We need to know exactly where we are and how we can get back to New York," Leo answered, "Let's take a look around. And let's not try and cause any trouble. That means you too, Raph." 

The red-clad turtle glared at that.

The Turtles then entered the country.

Elsewhere, at the castle. Queen Elsa and her sister Princess Anna were about to head out into town. The latter was practically dragging her elder sister out the door.

"Anna, I'm busy today," Elsa stated, "There's still a lot I have to do."

"Aw, come on Elsa," Anna complained, "You're always working. You have to get out more and have fun."

"I do have fun, Anna. It's just there's still work I have to do today, and the ball is tomorrow. I need to make sure everything's ready."

"I'm sure you can spare a few hours in town with me and Kristoff. Please?" The younger sister beamed puppy-dog eyes after that.

Elsa finally caved in, "Alright." 

Anna ecstatically bounced in place. 

"But only a few hours."

"Deal."

Once they left the castle, they met up with Kristoff. The younger sibling ran and embraced him in a hug. The queen smiled at the thought of Anna having someone who could make her happy. 

"Hi, guys!" 

They heard a voice, not from Kristoff called out. It was Olaf riding on Sven.

"Hi, Olaf" Anna greeted.

"You two didn't cause too much trouble right?" Kristoff inquired.

"Why would we cause trouble?" Olaf asked.

"He was joking Olaf," Elsa clarified, causing the snowman to laugh.

"Alright, come on! Let's go!" Anna persuaded as they head off into town.

A few hours had passed, and the sisters and their friends were enjoying the time that they spent in town. 

Another group was in the area, and only the members of this group were not enjoying their time. The disguised Turtles had been walking across the kingdom, hoping to learn more about its geographical location or anything else that could be useful. So far, they haven't. They would have stopped to ask somebody, but they didn't want to take the chance that the people would see their faces and inevitably chase them out of town like an angry mob.

"Well, Donnie, what do you make of all this?" Leo asked.

Donnie had been observing all the surroundings and people the whole time, "Well, from the looks and architecture of this place, it looks roughly around the 19th century."

"So these buildings are really old?" Mikey asked.

"I'm not so sure," Donnie stated, "From the people's overall attire and the lack of any technology, I'd say that we're not in Kansas."

"Are you saying we traveled back in time?" Raph asked.

"That's what I thought at first. But everyone's speech dialect seems equal to that of the present day."

"So, what are you getting at?" Leo asked.

"Best guess is that the Kraang's dimensional inducer may have zapped us and the Shellraiser to another world," Donnie hypothesized.

The remaining Turtles were shocked, to say the least.

"But it's just a theory," Donnie said, "I'll need more information."

"Alright, let's see what else we can find," Leo commanded.

About a block away from the Turtles' location, the royal sisters and their friends were walking in the same direction having just finished lunch.

"That was good," Kristoff commented as he patted Sven on the head.

"Not as good as some of the stuff in the castle, but it wasn't too bad either," Anna added, before turning to Elsa, "So, having a good time?" 

"Yes actually. This was pretty fun," Elsa admitted.

"Glad to hear it. You really should get out more often."

"Yeah, maybe we can make a snowman," Olaf suggested.

"I'm still the queen though. I have responsibilities, and thus I can't spend too much time outside the castle," the ice queen remarked.

"I know," Anna sighed, "But still you…." 

Before she could finish her sentence, they noticed something amidst the crowd of people. 

It was a man at a fruit stand being assaulted by four people. One was an overweight man with a beard, another was a woman with an eye patch, a skinny guy, and a buff man.

"Yeah, that's right," the fat man said, grabbing the owner of the stand by his shirt, "Pay up or get hurt."

This scene caught the eye of the four disguised reptiles as well.

"What's going on?" Mikey asked.

"Looks like some kind of protection racquet or something," Donnie theorized.

"Yeah, from a bunch of Purple Dragon wannabes," Raph growled.

"Whatever it is, I don't like it," Leo stated.

"I can't stand to see someone treated like that," Kristoff observed angrily.

"Neither can I," Anna agreed, "We have to do something."

Elsa put her hand on Anna's shoulder, "Anna wait. The guards can…" 

Before she could finish, she heard someone speak.

"Hey! Back off!"

Elsa looked and saw the source of the voice: a blue-robbed individual. With them were three other hooded figures: one in red, the other in purple, and the last in orange. She couldn't make out their faces, however.

This caught the attention of the thugs. They saw the four figures standing a few feet from them. 

The overweight one, apparently the leader, simply brushed them off, "Mind your own business." 

He was about to punch the stand owner, but his fist was caught by the wrist. He saw it was from the red-hooded guy.

"He said back off," the red-clad character reminded before shoving the fat man away.

"Oh look boys," the eye-patched woman observed, "We got ourselves a couple of wannabe heroes."

The fat man got up and approached the blue-hooded figure, "You punks gotta pay too. This is our turf, and here everyone's a dog." 

As he spoke, Leo could tell he and his brothers were not going to need their weapons, "Sorry, you're the one who's going to have to pay." 

"Teach these punks a lesson!" 

Raph smiled as soon as he heard that. He's been wanting to hit something all day.

The buff man tried continuously to hit Raph and bash him with his muscles, but Raph was easily able to avoid him. As the man tried to punch, the red-clad turtle grabbed him by the wrist and twisted it. The man was about to scream in pain when was punched right in the jaw, knocking him out.

The eye-patched woman took out a whip and proceeded to try and snap Mikey with it. To her surprise, the orange-donned turtle caught the whip and the end wrapped around his hand. He pulled her in and swung her into a stack of crates, one of which broke upon impact.

The skinny man took out an axe and tried to swing it at Donnie. The genius kept his distance with great ease. He could tell this man had little to no experience using the axe. The purple-clad turtle clapped the axe between his hands and slammed the flat end into the man's face. The goon clutched his face in pain, but Donnie kicked him in the gut knocking him to the ground.

The fat leader drew a dagger and was ready to impale his new enemy. Leo remained calm, for there was no reason at all to panic. This was an amateur. The turtles' leader just made a "come here" gesture with his hand. The obese man replied and tried to stab him, but with a flick of his hand, the blue-clad turtle knocked the dagger out of the man's grip. He then delivers two punches to the man's face before following with a roundhouse, knocking him out cold.

The disguised Turtles took a moment to observe their work, to which Raph was quite content. 

"Alright! I got to hit something," Raph beamed.

"Yeah! They just got shell-shocked, son!" Mikey agreed, earning a high-five from Raph.

"Umm...guys," Donnie reminded. 

They all looked around and had drawn quite a crowd. Many people were looking at them with stares. Thankfully no one could see their faces, so they maintained that part of their cover.

As he looked around Leo took note of a certain individual. It was a woman with platinum blonde hair and beautiful blue eyes. But what made her stand out, was a bright blue, sparkling, dress.

Elsa looked at the four individuals with awe. They at beaten those thugs in less than a minute. She could tell the blue-clad one was looking at her, though she could not see his face. 

Before anyone could make any movements, multiple palace guards arrived on the scene.

"Halt!" the leading guard shouted to the individuals. 

For them, it was time to go. 

"Mikey!" Leo called his youngest brother. 

Mikey knew what to do. He drew a smoke bomb and threw it to the ground and the four brothers were engulfed in a flash of purple smoke.

"Wait!" Elsa called out. 

But it was too late. The purple smoke had vanished, and the four hooded figures were gone, with no trace, save for the thugs they made quick work of.

"Your majesty, we will begin our search for those four felons," the guard leader stated.

"What?!" Elsa exclaimed, "They have done nothing wrong!"

"She's right," Anna stepped in, "They were defending this man from those thugs."

"We saw the whole thing," Kristoff added, "It's those four who should be punished." 

"Understood," the Guard replied.

The guards then made to arrest the unconscious thugs, though they had to carry them.

Anna was helping the stand owner to his feet, "Are you alright?"

"Yes. Thank you, your highness," he thanked the princess.

"Why were those men hurting you?" Elsa asked.

"They come around this area frequently, demanding protection money. I didn't have enough for them," the owner recounted, "If it weren't for those four hooded fellows, I don't know what would have happened."

"Well, you're safe now," Anna assured.

"Again, thank you," the owner said as he walked home.

"Who were those guys?" Kristoff asked.

"I don't know, but I like them," the snow queen's sibling commented, "Too bad they left, we could have thanked them. Maybe even made new friends."

"If it weren't for the guards trying to arrest them that is," Kristoff remarked.

"They could probably use a hug," Olaf suggested from on top of Sven.

As Anna and Kristoff laughed. Elsa looked up at the sky and wondered. Who were they? Maybe she would see them again. She couldn't tell why, but around them, she felt safe. She hadn't felt like that since before her parents died.

Meanwhile, the Turtles found themselves in Arendelle's sewers. Their hoods were lowered and their faces could be seen with their ninja masks still on, though they still wore their robes.

"Well, so much for not causing trouble," Raph criticized.

"Weren't you happy we beat up those guys though?" Mikey retorted. 

Raph then growled, but before anything could happen Leo interrupted, "It doesn't matter."

"Leo's right guys," Donnie agreed, "Besides we helped somebody, and we got away quickly. And you were happy you got to hit something, Raph."

"Okay, true," Raph admitted, "But now what do we do? We haven't made much progress as to where exactly we are, and now we probably got some guys looking for us."

"Maybe ask somebody at the party," Donnie suggested. 

The three other turtles looked at him, confused until Donnie pulled out a piece of paper, "Found this on a wall before we took down those jerks. It says there's going to be some kind of ball tomorrow night."

"A party? Awesome!" Mikey beamed, "That means there's gonna be pizza!" 

To that statement, the other turtles rolled their eyes.

"Alright, where's the ball?" Leo asked.

"It's at the palace tomorrow night," Donnie answered.

"Okay, so we'll head there tomorrow and ask the king, or queen, or someone about this place to know more about where we are exactly." Leo planned.

"But dudes!" Mikey said as he took the paper from Donnie and looked at it, "It says that to attend, you must have an invitation."

"We're ninjas, remember?" Raph reminded Mikey, "We'll just sneak in. Besides, it has to be  way  easier than sneaking into Shredder's lair or a Kraang base."

The Turtles had their plan. 

However, something else was on their leader's mind, which the others didn't seem to notice. Leo couldn't help but think about the woman he saw. Was she a princess? Royalty maybe? Something about her felt weird. Not the evil type of weird, but it's something else. The feeling is different than any human they had met before. Something told Leo was going to find out sooner or later.

Later that night, in a dark cell room, a man sat on a wooden chair, his face concealed by the shadows. He appeared to be waiting for something. Soon there was a knock on the door. 

"Come in," he responded.

The door opened, and the man that entered was the Duke of Weselton.

"They have arrived," the Duke said.

"Excellent. Send them in." 

Two men soon entered.

"Sir, we are ready," one of them announced.

"Good," the shaded man remarked, "Their queen is hosting a ball tomorrow night. I want you men to go there and do what you do best." 

At that statement, the men formed sinister smiles on their faces and they and the duke left.

Moonlight then peered through a window in the room, revealing the man's face. It was Hans.

The Castle

Elsa had just awoken from the sun gleaming from her window to her face. She honestly felt like going back to sleep, but she had to ensure everything was ready for the ball tonight. She pulled herself out of bed to get cleaned up and dressed.

When she left, she was ready for the day. Before she could move another inch, she heard her sister call out her name.

"Elsa!" Anna exclaimed from the other side of the hall. 

Elsa was a tad startled at her presence.

"Anna, you're up early," Elsa observed as her sister ran up to her.

"I'm just excited for tonight! People, food, dancing; it's going to be great!" Anna bounded excitedly.

"I know, I just hope it won't end like my coronation party."

"Why would it end up like that?"

"It was a joke."

"Oh, I see."

"I'm sorry, I'm not too good with jokes."

"No, no. You're trying new things, you were trying to be funny."

Elsa smiled at that remark, "I have to make sure everything's ready, go on ahead, I'll meet you downstairs for breakfast in a little bit."

The queen's sister nodded happily and ran off.

Once Elsa was all alone, her mind drifted back to what she saw yesterday, those four hooded heroes. She couldn't stop thinking about them. Why were they disguised? Who were they? It was amazing how they took down four armed criminals with no sweat in less than a minute. Maybe she would try and go looking for them tomorrow after the ball. But she brushed that thought aside, realizing the guards would follow her, as per their duty, and they would just vanish again. Something told her she wasn't going to see those four unless they wanted her to.

The cloaked Shellraiser

The Turtles had just woken up from sleeping in the chairs at each of their stations from inside their assault vehicle, still cloaked to avoid any attention. It was still where they left it by Oaken's Trading Post and Sauna, with no one around during this time.

They each groaned as they woke up and stretched. The Shellraiser seats weren't exactly comfortable beds.

"Alright guys, the plan's today," Leo reminded his brothers.

"What plan?" Mikey asked, to which each of the Turtles facepalmed.

"The ball tonight Mikey?" Donnie told him. Mikey still looked confused.

"Sneak inside, talk to whoever's ruling this place, find out where we are?" Raph reminded.

Something in Mikey's mind snapped, "Oh right the party! Sorry, crazy dream last night. All four of us were in a hot tub, then Shredder showed up, and we kicked his butt, and after that…"

Before he could continue, Raph interrupted.

"We don't need or want to hear it, Mikey," the muscle of the team told him.

"Come on people, we need to get ready," Leo instructed. 

He got into his driver's seat and started the Shellraiser, still cloaked. Leo drove it slowly to make as little noise as possible. After about 20 minutes of slow driving, he parked the invisible vehicle, right outside the kingdom.

"Why park so close?" Donnie asked.

"If something happens, and we need to make a bee-line out of here, we have the Shellraiser to get far away as fast as possible," Leo answered, being prepared for the worse.

"Why do we have to get ready now? The ball isn't till tonight and it's morning," Raph asked.

"We may not be sneaking into an enemy lair, but after what happened yesterday and attracting unnecessary attention, I'm not taking any chances," Leo told him.

"You never take any chances at all Leo," Raph criticized.

"Better safe than sorry," the leader clarified, "Besides, do you like being chased by an angry mob?"

"No," Raph grumbled.

After getting their robes, the Turtles entered the kingdom. To avoid being recognized, they stuck to the rooftops. While they moved from building to building, Mikey looked down, frustrated. He shook his head and looked at the same spot and saw nothing. He could have sworn he saw a little snowman riding on top of reindeer, but he just brushed that off. Even  he  knew that was impossible.

Unknown to anyone in the kingdom, disguised mutants included, there was another party sneaking around. Within the sewers of Arendelle, there were at least a dozen men, each wearing black robes, walking in the direction of the castle.

"Ugh, it smells worse than my grandma's feet down here," one man complained.

"Why do we have to walk in the sewers?" another man asked.

The man up front, apparently the leader, answered, "To avoid drawing attention, I'm pretty sure a dozen guys each wearing convenient black robes isn't exactly a common sight even in this kingdom."

"What's the plan again?" one man asked.

"To keep it simple, we sneak in, kill the queen, grab the princess, and get back to the ship," the leader reminded the group.

"Why not just kill both of them?" a different man asked.

"Hans specifically said he wants the princess alive and brought to him," the leader answered.

"Why do we have to kill this queen though?" a guy in the back asked.

"Don't tell me you're going all sentimental on us," the man next to him criticized.

"Of course not," he defended, "It's just...she is some sort of ice witch. She can make fortresses of ice and create snow monsters just by thinking. Killing her ain't going to be easy."

"A job's a job," a man in the center told him, "We do this, and Hans and that duke guy make us rich men."

"Why do those two hate the queen and princess so much?" a different man asked.

"I don't ask questions to the guy with the money," the leader told them, "It's simple; people hire us to do something, we do it, and they pay us."

The gang continued their trek through the sewers heading toward the castle.

The Castle

It was late afternoon, and most of the guests had already arrived. The decorations and the food were made, and it was all set. Everything appeared to be going well. Everyone was dancing to the music and enjoying a good time.

Outside the castle, two guards were at the gates keeping an ever vigil eye, prepared for anything. However, they were only looking up in front. Below the bridge leading to the gate, in the water, the Turtles slowly and quietly rose from the water and climbed the wall to the rooftop of the castle. The guards noticed nothing. 

Once on the rooftop, Donnie took out a waterproof sack and opened it. Its contents are their dark-colored robes, and the Turtles each took one and quickly and quietly made their way to a window. Leo drew a small blade and cut a small hole in it, he reached inside and found the latch, he pulled it and the window opened. 

They made their way inside. The robed turtles stuck to the ceiling beams and shadows once they entered the main ballroom. It looked smaller from the outside, but despite the massive size, they were able to get a close look at everyone below them. They saw everybody dancing and heard all the music playing, and their keen senses even picked up little bits of conversation. They couldn't quite make it out over the music though.

"So who do you think's in charge here?" Donnie asked. 

Before anyone could answer, the music stopped and everyone then clapped. A man in green, and a bit overweight, stepped up near what appeared to be a throne at the end of the room.

"Queen Elsa of Arendelle!" he announced as a woman in a sparkling blue dress and platinum blonde hair stepped up, whom Leo instantly recognized. 

"Princess Anna of Arendelle!" he also announced as a younger woman in a green dress ran up excitedly next to the queen. Everyone soon applauded.

"Guess that answers that question," Donnie said.

"Hey bros, isn't that the same woman we saw yesterday?" Mikey asked.

"Yes, it is," Leo answered.

"So who's the girl next to her?" Raph asked, "If that's the queen, then is she her daughter?"

"I don't think so. They look roughly around the same age, more likely they're sisters," Donnie theorized.

"Well, now we know who's in charge, let's go," Raph stated.

"Hold on Raph. Remember what I said about being chased by an angry mob?" Leo reminded.

"Then what are we supposed to do?" Raph asked.

"We know she's the queen, so we wait till the party ends and the guests all leave, then we ask her," Leo clarified.

"So we just sit here doing nothing? Great," the red-clad turtle uttered sarcastically.

"Ever heard of something called 'patience', Raph?" Leo criticized, "You should try it sometime. It's really helpful."

Below at the party, Elsa seemed rather happy. She saw Anna go off to dance with Kristoff. The monarch greeted a few guests, had some small talk with them, and ate a few snacks. Everything seemed to be going well. Olaf was not present; she told him that this kind of party isn't something he would like, so he went with Sven to play outside. The thought of the four individuals was pushed to the back of her mind, but she couldn't help but wonder.

Outside the castle

A few hours had passed. It was nighttime, and the ball was still going on. The two guards were still keeping watch. 

One of the guards was suddenly pulled over the end of the bridge he was closest to. The other guard looked, but before he could do anything else, he was pulled over his end. Two black-robed men, each carrying a knife dripping in blood, climbed over. The other men had climbed over as well.

"You all know what to do," the leader reminded. 

They all nodded and went toward the castle. The leader then bore a sinister smile.

The leader and two other men walked toward the main entrance, while the others went to the side of the entrance by two large stained glass windows on each side of the main door. As the three walked in, they caught notice of the queen. The leader nodded to one of his men, who nodded back and began to make his way toward her, while he and the other man sunk toward the corners of the wall they were closest to.

During the hours that passed, the Turtles just continued to watch from the ceiling beams. Leo kept his eyes focused on the queen the whole time. There was something about her that he noticed. He wasn't falling in love, but he could sense something from her, something no one else he ever met had; it was unusual. When he took his eyes off her and onto his brothers, he noticed one was missing. 

"Where's Mikey?" he asked.

Raph and Donnie exchanged glances, for they were not watching him. Before they could worry, however, Mikey came back with an armful of food. 

"You know something bros?" he asked as he stuffed himself, "I've looked everywhere, tried every piece of food here, but I noticed something important..." 

"..."

"...there's not a single slice of pizza!" 

His brothers groaned and rolled their eyes.

"Seriously, what kind of party doesn't have pizza?!"

As Raph rolled his eyes, he caught something, "Hey guys, look down there."

They all looked and saw three men in black robes enter the ballroom, with two sinking into the corners and one walking to the other side.

"Who are those guys?" Donnie asked.

"I don't know, but something doesn't feel right about them," Leo observed. 

He took a closer look and saw the man was carrying a short sword under his robes. Leo was liking the situation less and less. He saw the man walk towards the side of the room in the shadows. No one else could see him, but the Turtles still could. The leader saw the man slow his pace as he neared the queen, and began walking toward her. Putting two and two together, he realized the man's intention. 

"Guys!" 

They all looked and they all knew what was going on, and they knew what Leo was about to do next.

"What happened to 'waiting till the party ends'?" Raph asked, with a half-smile knowing where this was going to lead.

"Change of plans," Leo stated simply as he drew one of his katana blades.

Near her throne, Elsa stood and smiled, believing everything was going well. She didn't notice the man coming up behind her. Anna however did notice, having gained a suspicious look, but suspicion turned to fear as the man drew a short sword. She knew what he was going to try and do. 

"ELSA!"

Elsa heard her sister shout her name and turned toward her. The next thing she heard was a whoosh sound and metal colliding behind her. She turned around and was stunned at what she saw: the mysterious figure in dark blue robes was standing behind her, his back facing hers, blocking a black-robed man's sword with his own.

The assassin looked in shock. He was about to kill the queen right then and there, but a blue-robbed guy, whose face he couldn't make out, had just come out of nowhere and blocked his blow with his sword.

Leo took advantage of the man's surprise and kicked him away. He turned and saw the queen look at her savior. She still could not see his face, but everyone else in the room had grown quiet and was staring at the two, trying to make sense of what just happened.

The black-robed leader slapped his face, "So much for subtlety." 

He nodded to his man on the other side. They each knocked on the stained glass window they were near. That was the signal, and all the other men smashed in through the windows. They each discarded their robes, revealing themselves. They had the black garb of professional assassins and mercenaries; each bearing a sickle, sword, multiple knives, axe, hammer, chain, and other crude weapons.

All the guests were starting to panic as they all tried to leave. They all piled out through the main door, and Kristoff got pulled with them. He was trying hard to resist, but the current of panicking people was stronger.

Leo drew his other katana and stepped in front of the queen, "Stay behind me."

Anna was by a pillar near the end of the room, she recognized the blue-robed stranger from yesterday. Why is he helping her sister?

The room was then cleared of people, save for the dozen killers, queen, princess, and disguised mutant. 

"Out of the way, pal!" the leader called out, "If you value your life."

"You want her? You gotta go through me first," Leo declared.

"In case you haven't noticed, there's a dozen of us and only one of you."

"Better count again!" 

It came from a red-clocked figure as he landed on the ground.

Raph drew his sai as soon as he landed. Mikey and Donnie followed suit and drew their weapons as well.

Elsa and Anna were each surprised, to say the least. The four heroes they saw yesterday were all here coming to their defense. The ice queen was starting to get worried since despite these four being brave, they are facing near-impossible odds. It was four versus a dozen. Unknown to her, they had worse odds before.

Leo noticed one of the mercenaries in the back drawing a small bomb and lighting the fuse. Knowing his intention, Leo got ready. 

As soon as the bomb was thrown, Leo tackled Elsa away to the ground, and the bomb exploded close to the two.

Raph, Donnie, and Mikey turned to their brother, while Anna turned to her sister.

As the dust settled, Elsa had her eyes closed and was coughing. 

"Are you alright?" a voice just above her asked. 

She opened her eyes and turned to her savior for an answer, but her eyes widened in shock.

"What?" Leo asked as he saw the queen just staring back at him with eyes so wide, they were almost circular. 

Leo turned and saw the princess staring wide-eyed as well. The same thing was true for all the assassins. He wondered what they were staring at. He got his answer when he got up and looked down at himself. 

His body was unscathed, but his cloak was in tatters. Everyone in the room could see him with no robe; they all saw the six-foot-tall, humanoid turtle, with a blue mask holding two swords.

"Whelp. So much for disguises," Raph said. 

No longer feeling a need to maintain cover, he, Donnie, and Mikey each threw away their robes, revealing themselves as turtles as well to everyone else, earning even wider eye stares.

The Teenage Mutant Ninja Turtles each had weapons at the ready and were all set to crack some skulls.

Chapter Text

A mercenary got tossed into a table having all the food on it. Once he crashed into it, all the food splattered on him. As soon as he was done seeing stars, he lost consciousness.

Another mercenary was attempting to slice Leo to bits with his sickle, to which Leo blocked with one of his katanas and delivered a knee straight to the face. Another attempted to hit him behind with an axe, but Leo sideswiped him, swept him off his feet, and sliced him across the chest. One thing was sure, these guys were good, but not good enough.

Donnie was facing three mercenaries. Donnie had his bo at the ready, but once they saw it they started laughing. 

"You're going to beat us with a stick?!" the mercenary said as he laughed, only to get bashed across the face and sent flying several feet, much to the other two's shock.

"It's a really good stick," Donnie said with pride. 

The other two got serious and soon charged in with their weapons as well.

Raph had two mercenaries coming at him: one with a hammer, the other with a sword. He was quick enough to avoid both. The red-clad turtle jumped between the two pillars nearby him. Once he was high enough, he jumped down and slammed both his knees into the face of the hammer wielder. The swordsman tried to swing at him, but he caught the sword between his sai. At first, they appeared to be at a standoff, but with the twist of his sai, Raph snapped the sword in half and delivered a kick to the guy's face.

Mikey was bashing a large mercenary with his nunchucks like a piñata. Once the guy was bruised enough, the orange-clad turtle delivered a punch to the gut, incapacitating him. He was soon surrounded by two more bad guys. 

"You think you're tough?! Huh?! You suckers wanna piece of me!?" he shouted to them before charging, "Booyakasha!"

Elsa, who was hiding behind a pillar on the other side of the room, couldn't make sense of what had recently happened in her life. Just yesterday, four mysterious hooded figures saved a man from being assaulted by dangerous criminals, defeated them with ease, and vanished in a purple cloud of smoke. Then a few minutes ago, she was saved from an assassination attempt by the very same strangers who just happened to be in the same room of all places. Now it's revealed that these strangers are walking, talking, man-sized turtles - TURTLES! And now these Turtles were defending her from over a dozen assassins and killers, and these creatures appeared to be winning, which is why she had yet to use her powers.

Anna, who was hiding behind the pillar next to her sister, was watching in both amazement and shock. These mysterious heroes had just come to her sister's rescue. They were the same heroes who saved that man yesterday. Now they were beating up dozens of bad guys all by themselves. Though she had no idea they were who they are. No wonder they were wearing disguises.

Kristoff, breaking free of the panicking crowd outside, was able to make his way back inside to see what was going on. Once he got in, his face had the greatest look of surprise in his life. He saw Anna behind a pillar and made his way to her. 

"Um. What did I miss?"

"Oh, nothing," Anna replied, not taking her eyes off the battle, "Just that those four guys we saw yesterday were giant turtles. One of them just saved Elsa, and now they're fighting the same people who are trying to kill her."

"Oh," that was all Kristoff could say at the moment, as he found himself soon intrigued by the battle happening in front of him as well.

"What the hell is going on?!" one of the mercenaries asked his leader.

"Hell if I know! I knew the queen was powerful, but I don't think anyone knew she had demons by her side!" the leader said. Demons were the only thing he could think of as he saw them make quick work of his men.

"Demons who just happened to know Kung Fu?!" the mercenary asked completely frustrated.

"We're not demons, you idiots!" Raph shouted as he overheard them.

"Yeah, and it's not Kung Fu! It's an ancient Japanese battle art!" Donnie corrected in a know-it-all type fashion, to which Raph rolled his eyes and got back into the fight.

As the Turtles fought through the bad guys; hitting, kicking, punching, beating, slicing, and batting away, they were sure that none of their attacks were fatal in any way. Call them what you will, but the Turtles never kill. They never have killed, and never will...well, except for maybe  him .

A killer had come at Mikey with his spear. As he lunged, the orange-clad turtle wrapped the end of the spear in his chain and shoved the flat end right into the wielder multiple times, before swinging the spear around in his chain and bashing the guy across the face. Another guy came at him with an axe from behind, but he was quick to jump away. While in the air, he extended the chain of one of his nunchucks and wrapped the guy up in it before pulling him in straight to Mikey's foot. 

"Word!" Mikey shouted as the guy fell to the ground.

Donnie's staff collided with a killer's sword. But Donnie twirled his staff and tossed the sword out of the man's hands, then bashed him in the knee. As the man grunted in pain, the purple-clad turtle elbowed him in the face. Out of the corner of his eye, he saw a bomb flying toward him. He just batted it away like a baseball toward the thrower. When it blew up, it knocked the wearer back, but it didn't kill him.

One mercenary had his knife at the ready and was steadily approaching Donnie, ready to plunge the knife into his neck. Before he got too close, however, he felt a tug on his shoulder. As he turned around he saw Kristoff deliver a punch to the face, knocking a tooth out in the process.

Donnie heard a grunt behind him and turned around just to see a killer fall behind him. A knife fell out of the killer's hand just as landed. He saw Kristoff pulling his fist back. They both briefly shared eye contact. They smiled and delivered quick thumbs-ups before heading back into the fight.

Raph was quick to avoid a whip in his direction. He then did a barrel jump right over the man and landed behind him. The Turtle then grabbed him by the neck and heaved him over his shoulder, tossing him into another bad guy heading his way.

The red-clad turtle turned and saw a rather large guy carrying a chain with a hammer attached to its end. The man swung it around in an attempt to show off, it had little effect. 

"Fancy weapon there, pal," Raph said with a cocky smile, "Let's see you use it."

The man accepted the challenge by swinging the hammer end at him. Raph simply jumped over it before it made contact with the ground, leaving quite the impression. He landed on the hammer's head and severed the chain with his sai. The man was in complete shock and could not react fast enough before Raph delivered an axe kick and knocked him out, all while grinning from ear to ear.

Leo had two men coming at him from each end, both with hammers. They had the idea that if they double-teamed him at the same time, he couldn't counter. They were wrong. All he had to do was evade at the right moment and the hammers each made contact with the other guys' faces. This knocked them both out, without Leo so much as throwing a punch.

Leo turned to the leader, who was holding two swords of his own. He was the only one left.

"Really?" Leo asked with a cocked eyebrow.

"What are you talking about?" the leader asked.

"Dude, all your buddies are down for the count. You're all that's left," Leo told him.

"Doesn't matter. I'll just kill all of you myself!" the leader tried to instill fear, but his intention completely failed.

"Don't make threats you can't follow," Leo advised, "Just make it easy on yourself and surrender."

"Shut up you FREAK!" the goon shouted, losing all sense of doubt and possibly sanity as he charged in with both swords.

Leo's swords collided with the mercenary leader's. Though he was just blocking all of the guy's attacks, it didn't take too much effort to do so. Maybe a little, but not a lot. Once their swords collided and locked, they appeared to be in a standoff, but appearances can be deceiving.

"You're good," the Turtles' leader admitted, before headbutting the man in the head, "But, I'm better." 

As the leader clutched his head in pain, he dropped his swords. Leo then delivered a kick in the chest and made two diagonal slices with his katanas across the leader's chest. They did penetrate the skin but were not deep enough to be fatal.

The man fell to the ground and saw the blue-masked turtle pointing his blade at him, with thin blood dripping off it. 

"You've lost," Leo declared.

"WHAT THE HELL ARE YOU?!" the man demanded.

"The Turtle who just beat you," Leo knocked him out with the blunt of the blade's handle.

Raph, Mikey, and Donnie soon came to each other in the center of the room and congratulated each other with high fives and fist bumps. 

While amid the three's celebration, Leo came in and broke it up, "Not exactly the time to celebrate guys."

"What do you mean?" Raph asked, "We just kicked major butt."

"Yep, I'd say it's a perfect time," Mikey agreed.

"I beg to differ," Leo said as he pointed in a certain direction. 

The other turtles turned to where he was pointing to. It was the queen.

"Oh. Forgot about her," Donnie admitted.

Elsa just stood there, completely frozen. Her mind trying to process what had just happened. These turtlelike creatures had just defeated over a dozen professional assassins. From their garb, she could tell these men were not amateurs. Four common criminals are one thing, but this...four against a dozen, and the four came out on top. She still could not get over the fact that they were turtles. That was hard even for her to believe. She had seen little trolls made of rocks, created two living snow beings, and an entire palace made of ice, but could not wrap her mind around the four-armed, talking turtles who could fight like no one she has ever seen. Then again, she was isolating herself most of her life, but still.

The Turtles felt the awkwardness of the moment seep into them, but before anyone could dwell on it, they heard a massive door slam open. They turned and saw half a dozen Arendelle guards, each armed with crossbows.

The guards heard of the emergency and came running as fast as they could. But they were completely unprepared for the sight that stood before them. Any guard, that did not have their eyes bulge out at the four man-sized turtles, had their jaw dropped.

"Captain, what are they?" one guard asked.

"They must be demons," the captain guessed, "They've come for the queen! Prepare to fire!" 

All their guards had crossbows primed and at the ready.

Mikey was ready to toss down another smoke bomb, and the four would make like piñatas and beat it. But before they could…

"WAIT!" Anna shouted as she jumped in front of the turtles, "They're not demons! They saved my sister's life!"

The guards each exchanged confused looks. The Turtles were a little surprised themselves. It was rare that a human came to their defense, even rarer when it was a first meeting.

"She's right," Elsa added, as everyone then had her eyes upon her, "These four, um, turtle creatures…came to my defense. They saved me from them." 

She gestured to the ground, littered with the many unconscious assassins. The guards all looked upon the ground and saw the many KO'd bad guys. 

"How did we miss that?" one of the guards asked.

"It's true," Kristoff added, "We saw the whole thing."

"But your majesty," the captain said, "these… these… mon…" 

Before he could finish his sentence, the queen interrupted, "I'm not exactly sure what they are. But I do know, that they are not evil. If they had come for me, I suspect I would already be their hostage, or dead."

"What would you like us to do then?" the captain asked.

"I want you to take these men, and escort them to the dungeons," Elsa commanded, pointing to the floor of unconscious crooks.

"As you wish," the captain said.

The guards then quickly gathered all the knocked-out mercenaries and carried them off. Anyone who came close to the Turtles would try and avoid looking at them.

The Turtles remained in their spot, to try and avoid any unnecessary conflicts; even Raph knew when not to fight. They were also quick to put their weapons away, to show they meant no harm.

Once the last of the guards was about to leave the last of the mercenaries, Elsa came over to him.

"Please make sure the guests are alright," she told him.

"Yes, your majesty," the guard said.

"And close the gates behind you."

To which the guard nodded. It was to make sure no one else could catch a glimpse of her saviors and have a heart attack or start a panic. Once it was done Elsa closed the doors, and the only ones left in the room were Elsa, Anna, Kristoff, and the Turtles. 

After a minute or two of awkward silence, Elsa tried breaking it, "So um… thank you, for saving my life."

"No problemo," Mikey replied, "It's what we do."

"Right. Well, I believe introductions are in order then."

"Your majesty," Leo began, "My name is Leonardo, and these are my brothers. Donatello, Michelangelo, and Raphael."

"A pleasure," Elsa greeted, turning their attention to each of the other people, "Queen Elsa, of Arendelle. This is my sister Anna. And the kingdom's ice master, Kristoff."

"Nice to meet you," Kristoff tried greeting.

"Um, yeah," Donnie said.

"Oh thank you, thank you, thank you for saving my sister!" Anna said excitedly as she ran up to Mikey with a hug, which surprised him a bit.

Before anyone could say anything else they heard someone walk in and start to talk, "Wow! Must have been some party." 

The Turtles looked around for the source of the voice. They saw a reindeer standing in the doorway, but they knew it wasn't from him.

"I don't know what happened, but it must have been fun," the voice said, "Oh, Hi new friends." 

The turtles then turned to the source of the voice. It was Olaf.

Mikey screamed at the sight of him and bashed his head to the other side of the room with his nunchuck. The other Turtles got their weapons ready to fight, but Anna jumped in their way.

"No! It's okay! He's a friend," the princess told them.

"What the hell is that?!" Raph asked.

"Don't worry. He's friendly," Elsa added.

"It's… it's a talking…snowman," Donnie sputtered.

"Well, you guys are talking  turtles ," Kristoff told them.

"Umm...talking snowmen aren't a common sight where we're from. And believe me, we've seen plenty of crazy things," Leo said.

Anna then came to Olaf and helped put his head back on. 

"Whoa! That was a head rush!" the snowman said.

"You okay Olaf?" Anna asked with concern.

"I'm good. Okay, let's start over." 

He walked to the turtles with open arms, "Hi I'm Olaf, and I like warm hugs."

The turtles just stared at him.

"Does he want us to hug him?" Donnie asked.

"Well I'm not hugging him," Raph said.

"Sorry." Leo apologized to Olaf, "We don't hug people we just met."

"Aw," Olaf lowered his arms.

"A talking snowman," Donnie said, "How's that even possible?"

"Oh, Elsa made me," Olaf stated.

The Turtles then turned to Elsa with wide eyes at that statement. She slightly looked away.

"You made him?" Mikey asked.

"It's a little complicated."

"Well, we just need to ask you a few questions," Leo said, trying to lower any tension, "Tell you what though, we'll tell you our story. Then you can tell yours, and we'll just ask what we need to know. Sound good?"

The monarch was a tad bit surprised. She had just met these beings, and already they were going to tell her their story. She did find them incredible and would like to know how they took down a dozen trained assassins.

"Sounds great," Elsa said with a smile.

Chapter Text

The gates to the castle were closed. The guards were outside making sure no one could catch a glimpse of the Queen's newest "guests".

Within the castle, Elsa sat on her throne with Anna and Kristoff sitting in chairs on her right, and Olaf sitting on the ground on her left. Their new Turtle friends were about to tell them their story. Elsa was interested to hear their story. Anna and Olaf seemed quite excited. Kristoff just wanted to know what they were all about, with Sven sitting next to him.

"Alright," Leo started, "Sixteen years ago, there was a man named Hamato Yoshi. He is a truly great person; wise, strong, and compassionate. He was also a grandmaster of ninjitsu."

"What's Ninjitsu?" Anna asked.

"Ninjitsu is an ancient martial art that originated in feudal Japan," Donnie described, "It focuses on stealth and power."

"Stealth?" Kristoff asked, "No wonder you guys got in without anyone noticing."

"Anyway," the leader continued, "Yoshi was one of the greatest masters of Ninjitsu in the history of Japan. He is skilled in nearly every weapon and is incredibly wise. Only one person alive has skills that could rival his."

"And who's that?" Elsa asked.

"...no one important," Raph stated. The Turtles did not want to talk about  him  unless it was crucial.

"So, Yoshi left Japan for New York almost fifteen years ago," Leo continued.

"Where's New York?" Olaf asked.

"It's our home city," Mikey answered. 

With this the other Turtles then had the info they needed to confirm Donnie's theory: they were in another world. Leo went to continue the story.

"One day, he was leaving the pet store with four pet baby turtles…."

"Four baby turtles?" Olaf interrupted, "There's four of you, so…"

"You," Raph interrupted, getting close to the snowman's face, "Stop talking."

"But I…" Olaf was about to say.

"Olaf, let's allow our guests to finish their story. I'm sure they'll answer our questions then," Elsa said.

"Okay," the snowman replied.

"So," Leo began, "As Yoshi left the pet store, he passed a strange man on the street. He felt something strange about the man and decided to follow."

Elsa, Anna, and their friends (even Sven) were starting to get intrigued with Leo's story at this point.

"Yoshi had followed the man to an alleyway. He saw the man talking with three others, and carrying a mysterious package. Before anything else happened, Yoshi accidentally stepped on a stray rat and gained their attention. These men did not want witnesses, and tried to kill him."

Now the listeners were interested and got more and more as Leo continued.

"But Yoshi is not one to go down so easily."

"Seriously, you should have seen him," Mikey put in excitedly and as he explained, he motioned with airborne punches and kicks, "He was all 'Wham', 'pow', 'bang', 'chop'! And the bad guys were all 'ugh', 'ow', 'ew'."

Anna was especially excited at this, "This 'Yoshi' sounds amazing!"

"As Yoshi continued to fight, all while carrying his pet case I might add, one of the men dropped their package, which was a canister carrying a green glowing liquid," Donnie continued, "It smashed open, and out came the ooze, splattering over Yoshi. Once he got splashed, he dropped the case and the baby turtles fell into the ooze as well."

"The ooze then changed him. Yoshi had transformed into a humanoid rat," Leo stated. 

At that statement, the listeners (Sven included) had their eyes widened in shock.

"The ooze also affected the baby turtles, and changed them into, well, us," Leo said as he gestured to him and his brothers.

"So you were once ordinary turtles?" Elsa asked, "And this 'ooze' changed you and Yoshi just because it touched you?"

"The ooze is a type of mutagen," Raph said.

"What's mutagen?" Anna asked.

"It's this liquid substance that can change whoever touches it into the last living thing they touch," Donnie said, in a way so they understood.

"What do you mean by that?" Kristoff asked.

"Okay," Leo started, "Let's say a guy was petting a dog, and soon got sprayed by the mutagen, because he touched a dog beforehand, he will transform into a part-man, part-dog creature."

"So, if I touched a cat," Anna started, "And I got sprayed by this 'mutagen' I would turn into a part girl, part cat?"

"Yeah pretty much," Mikey said.

"When someone or something goes through a change like that, they are called a mutant," Donnie stated.

"And that's what we are: mutants," Leo said.

"So, Yoshi, is a mutant now?" Elsa asked.

"Yes." Leo answered, "Since man-sized rats and turtles were not a common sight even where we come from, Splinter fled into the sewers with us."

"'Splinter'?" Kristoff asked.

"That was a nickname Yoshi got while he was in Japan, Master Splinter," Donnie said, "And after he got mutated, he now prefers to be called that, rather than 'Hamato Yoshi'"

"Why did he take you with him?" Anna asked.

"Splinter, I guess, felt responsible for us. So he took us into the sewers. He found an old drainage juncture in the sewers, and decided to make that our home," Leo continued.

"We were still babies at the time, so we followed Splinter everywhere," Raph stated.

"Splinter raised us and taught us what he knows about ninjitsu, so if we ever get into any trouble, we would have the skills to get out of trouble," Donnie described.

"So that's how you fight so well," Kristoff said, putting two and two together.

"Splinter became our master, our mentor, and our father," Leo said.

Elsa and Anna smiled at this, hearing the mention of a family.

"So, you all spent your whole lives in a sewer?" Anna asked.

"It wasn't that bad," Leo said.

"We were near an abandoned tunnel, and away from all the gross stuff," Mikey added.

"And it wasn't our WHOLE lives," Donnie also added.

"We got to go out into the city at night a couple of times, and get some exercise," Raph put in.

"But still," Elsa said, "To live your whole lives in secret? I mean, there have to be some people who know about you."

"Well, yes there are," Leo began, "But, only a few of them are our friends."

"And all the others?" Kristoff asked.

"They pretty much want us dead," Raph stated rather bluntly.

"Why would they want you dead?" Anna asked.

"Do you mind if we don't get into that?" Donnie asked, not in the mood to discuss their many enemies.

"But…" Anna began but was stopped when Elsa put her hand on her sister's shoulder.

"Anna, this may be a difficult subject for them," Elsa said, "Let's just let them continue," 

Anna then nodded at that.

"Even though we try and keep our existence quiet, we still do what we can help," Leo said.

"We've beaten dozens of bad guys," Mikey stated excitedly. 

This got Anna interested.

The Turtles began to tell about some of their adventures: rescuing people, fighting evil mutants, and saving their world a few times. Elsa, Anna, Kristoff, Olaf, and Sven all listened in amazement. All the while, the Turtles left out details regarding certain creatures from another dimension and a specific murderous psychopath.

"You guys are amazing!" Olaf stated.

"Yeah, they are!" Anna agreed.

"Alright, your turn," Raph stated before looking at the monarch, "Olaf, here, said you made him. What did he mean by that?"

Elsa looked down for a bit. Leo noticed.

"Hey, if you don't want to talk about it, it's cool," he said, trying to make the host feel more comfortable.

"No," Elsa said, "You told us your story. It's only fair I tell you mine. But, maybe it would be easier if I showed you."

The turtles all looked at each other in confusion.

Elsa slowly got up and walked to the center of the room. The Turtles, Anna, Kristoff, Sven, and Olaf followed. Elsa took a deep breath, and began to circle her hands. A snowball began to form, causing the Turtles' eyes to widen.

The ice queen threw the snowball up into the air, which shot up like a missile and exploded right before it hit the ceiling, and snow fell to the ground.

The Turtles looked around the room in amazement. Elsa was prepared for the worst, believing first impressions of her abilities were not very friendly.

"THAT IS AWESOME!" Mikey shouted in amazement, causing Elsa's eyes to widen.

"Yeah, not bad," Raph agreed.

"Incredible," Donnie stated.

"You can make snow?" Leo asked, "Wow, that's a nice little gift you got there."

The blue-clad turtle turned to Elsa who was staring at them in disbelief.

"Are you alright?" he asked.

Anna came up to Elsa, "Yeah. It's just the first positive reaction she got for her powers."

"What do you mean by that?" Leo asked.

"How long have you been able to do this?" Donnie asked as well.

"Ever since I was born," Elsa began, "When Anna and I were little, we used to play all the time with my powers. One time though, I hurt her by accident."

"Pfft," Raph began, being the tough guy, "What'd you do? She slipped on your ice or something?"

"No. I struck her in the head," Elsa answered, heavily breathing, "I thought I…killed her."

The Turtles smiles dropped at this, especially Raph's.

"We were able to heal Anna, but we had her forget about my powers," Elsa began, "My parents tried to help get it under control, but I couldn't, it just got stronger. As we grew up, I began to grow more distant from everyone, Anna included." 

She continued, "Until a few years ago, when my parents died, Anna was all I had left. Even then, I still shut her out. I was just…afraid."

"Dude, self-isolation?" Mikey commented with sadness in his voice, slowly tearing up, "That is so sad."

"A couple of months ago, I was made the queen, and that's when things started to go bad," Elsa continued, "During my coronation party, I used my powers by accident, pretty much everyone in the kingdom saw it. Some even called me a monster, so… I… I ran away."

The Turtles listened to the rest of her story: how she ran away, accidentally set her kingdom into an eternal winter, accidentally froze Anna's heart, and how Anna almost died. 

This was one of the most heartbreaking stories the Turtles ever heard, even Raph was saddened. But grief faded when Anna told them that she was able to help her. Her heart was thawed, and her kingdom was saved. Now everyone knew about her powers, and all were happy. Though they left out the part about a certain prince. 

The Turtles were relieved to hear how things worked out. They were impressed by Anna's determination to help her sister. Leo felt Elsa's pain in more ways than one, he could understand her situation a bit.

"I'm glad things worked out for you," Leo said.

"Thank you," Elsa replied.

"So what are you guys doing in Arendelle?" Kristoff asked.

"Well we were fighting an enemy of ours, and one of their devices sent us here by accident," Donnie told them.

"We were wondering, is there a place nearby we can stay until we figure out how to get back home?" Leo asked.

"You can stay here in the castle with us," Anna recommended.

"Really?" Raph asked.

"No. We don't want to be a nuisance," Leo told her.

"We can't. Please, we don't get many guests here. Please, please, please, please," Anna, with puppy eyes, begged, causing Raph to look away.

"I insist. You four saved my life," Elsa said, "The least I can do is give you a place to stay."

"You sure?" Donnie said, "I mean if it's no trouble…"

"We have plenty of extra rooms here," Elsa said, "No trouble."

"Well, we are just teenagers. We can be a bit of a handful," Leo warned.

"Anna was a bit of a handful at one point, and I'm sure if I can control my powers now, we can handle four Teenage Mutant Ninja Turtles," Elsa said.

The Turtles all huddled and talked. They soon separated after coming up with a response.

"We would love to stay," Leo said. 

At this, Elsa smiled, Kristoff gave a half-smile himself, and Anna practically jumped up and down.

"Yay!" Olaf stated as he ran up to Raph and hugged his leg, much to the Turtle's annoyance.

Later that night, after the Turtles were shown to four individual guest rooms, Elsa went into her room. As she changed into her nightgown and went to bed, there are many questions she wanted to ask them. She was certain Anna wanted to ask more. Despite being nearly killed today, she was relieved and grateful. She had made new friends, who gave a better first impression regarding her powers. She fell asleep with a smile on her face.

Leo was looking at his room. It had a window, which gave a perfect view of the kingdom, especially at night. It had a large bed and a dresser. He unmasked, set his sword down, and sat to feel the bed. It was soft and comfortable. As he lay down, he thought about what happened. He and his brothers were zapped to a new world and saved a queen bearing incredible powers. He wondered what Splinter and Karai would think. Splinter might buy it, but his sister would need to see it; to believe it. The Turtles' leader, at the same time, sympathized with Elsa's plight. No one should ever have to go through what she did. He decided as long as he is here, he would do what he can to help her. He then drifted off into sleep.

Chapter Text

Elsa had just woken up. She was a tad excited today. wanting to know about her reptilian friends a little more. The ice queen quickly got cleaned up, changed into her blue ice dress, and set her crown on her head.

She opened the door, only to find Anna right outside about to knock.

"Anna? You're up early," Elsa observed.

"So are you," Anna replied.

"Well, I was about to greet the Turtles and treat them to breakfast," Elsa explained.

"I was about to get you, so we could do that," Anna told her excitedly, "I can't wait to hear more about all their adventures!"

Anna grabbed Elsa's hand and dragged her through the hall. They went to the room where Leo had settled into. 

Anna knocked on the door, but there was no answer.

"Leonardo?" she asked, "Are you in there?"

"Um, Anna?" Elsa said as she placed her hand on her sister's shoulder. 

The queen pointed down and they saw a note. It read, "Meet us in the dining hall, -Leo." 

They both looked at each other and went to the dining hall.

When they got there, they found Leo, Donnie, and Raph all sitting by the table.

"Morning, your majesties," Leo greeted.

"Good morning," Anna greeted back.

"Where's Michelangelo?" Elsa asked.

"Mikey's cooking breakfast," Raph said.

"Oh. I'm sorry, I should have…"

"Don't worry about it," Donnie interrupted, "We get up pretty early anyway."

"But, you're my guests," Elsa said, "You shouldn't have to make us breakfast."

"Hey, trust me," Leo reassured with a knowing smile, "When Mikey cooks, you have nothing to worry about."

In the kitchen

Mikey was looking through the fridge, "Now, what would make the best breakfast?" 

He later saw a whole bowl of familiar ingredients, "Duh, eggs!"

" I love some eggs for breakfast, " he sang, " I love them scrambled, yes, I do ." 

His tone changed to rapping, " But breakfast isn't hot. Without Orange Juice, son !" 

He threw six oranges in the air and nailed them with throwing stars. The oranges stuck to the wall, and the juice poured into the six glasses, without spilling a drop. 

" It just be bland, like sticky goop,"  he continued to rap, " Some protein from ham. Throw in garlic, and onions too."  

He threw diced meat and veggies into the bowl of scrambled eggs and mixed it all in. 

"But wait a second boom! If you please, I'm missing the important part, Cheese!" he got a block of cheese, threw it in the air, and sliced and diced it into little pieces with his kusarigama.

After a few minutes, the three turtles and royalty sisters were all sitting at the table. Mikey came in carrying and balancing all the plates of omelets and a plate carrying the Orange juice glasses.

"Breakfast is served!" he announced.

The Turtles and Anna all got smiles on their faces with that announcement, but Elsa looked concerned with Mikey balancing all that. 

"Um, can I help you with those, delicate dishes?" she asked.

"Nah, I got it," the youngest turtle replied.

Then in one swift motion, he threw all but the glasses in the air. With one hand, he grabbed each plate as it fell and tossed it like a Frisbee. Each plate slid along the table and landed at everyone's place with no damage at all. He then slid all the glasses along to each of the places as well. When all was done, he jumped right into his seat. 

"Dig in!" he initiated.

The Turtles wasted no time in starting their breakfast. Elsa was a little more cautious, not knowing what it would taste like. Anna took a bite. Her eyes went wide. She swallowed and a smile formed.

"Elsa, you gotta try this," she urged her sister, "It's so good!"

Elsa took a bite and smiled, knowing exactly what Anna meant, "This is delicious!"

"Told ya," Leo said.

"Yep, say what you will about Mikey," Raph began, "But he knows how to scramble an egg."

"Booyakasha!" Mikey replied.

"I'm sorry, 'Booyakasha'?" Elsa asked as she and Anna exchanged confused glances, "What does that mean, exactly?"

"No clue," Mikey replied, "But it's fun to yell."

They continued to eat. Anna had so many questions to ask, but the turtles didn't mind answering (though Raph was getting a little annoyed). She asked them about their weapons and how they worked, including what life in New York was like. Elsa was also curious. They told them that while it does have its beauty, it isn't exactly the world's friendliest city. They also talked about Splinter, the sisters were amazed at how well the Turtles described their 'father'.

"We really must meet Splinter one day," Elsa said.

"You would like him," Leo said.

Something then occurred in Donnie's mind. Once he finished his breakfast, he got up and walked off, "Be right back guys, there's something I gotta get."

"Where's he going?" Anna asked. 

The Turtles looked at each other and took a wild guess.

At the back of the castle, the three turtles were waiting for their brother to bring what they thought he was bringing. Elsa, Anna, and Olaf came out.

"What are you guys waiting for?" Elsa asked.

Before anyone could answer, the uncloaked, trademark Shellraiser of the Turtles drove up right in front of them. The royal sisters and the snowman all looked in amazement at the vehicle. 

The doors slid open and Donnie stepped out, "Now we can keep it close by, and not worry too much about it."

"What is that thing?" Anna asked.

"It's something great!" Kristoff exclaimed as he and Sven stepped out, carrying a few blocks of ice.

"Kristoff?" Anna wondered.

"My sled broke, and Donnie here offered me and Sven a ride," the mountaineer said. 

Sven then licked Donnie's face, to which Donnie smiled.

"To answer your question though, it's our mode of transportation," Donnie answered.

"It's how we get around basically," Leo translated, "We call it the Shellraiser."

"Awesome name, right? My idea," Mikey stated with pride.

"But shouldn't have horses or something pulling it?" Elsa asked.

"Come on inside and we'll show you," the leader said.

They all stepped in. Olaf, Elsa, and Anna all looked around, marveling at everything they saw inside it. Leo got in the driver's seat and started it. He drove the Shellraiser into the woods.

The three were knocked a bit at the sudden drive, with Anna looking outside, "How is it moving on its own?"

"It's not," Donnie exclaimed, "The Shellraiser is a vehicle, which means that it needs a driver. All these little machines inside help rotate the wheels and allow the driver to steer, accelerate, and stop it. No horses required."

"Hang on, guys," Leo said, "We're going for a ride."

Leo drove the Shellraiser in a bit of a joyride into the woods. He did swerves, turns, accelerations, and donuts, much like when they were first driving it. Everybody, even Elsa, was having fun.

They stopped and decided to head back. But Olaf took a look at Raph's station and saw a shiny button. 

"Oooh, this is pretty," he said as he was about to touch it.

Right when he did... 

"NOOOOO!" the Turtles yelled.

The Shellraiser's weapons activated. A cannon on top shot multiple trash balls rapidly, blasting many trees away in the process.

Raph took off Olaf's stick arm, his eye slightly twitching, "That would be the weapon's system. And you, don't touch anything!" 

With that, he shoved the stick arm into the snowman's forehead.

"That wasn't nice!" Anna criticized.

"Well, I'm not exactly a nice person," Raph replied.

Before Anna could say anything else, Leo put his hand on her shoulder while explaining to the princess, "Raph may have a bit of a temper, but there are dangerous things on here."

"He has a point, Anna," Kristoff admitted. 

Anna conceded and the Shellraiser drove back to the castle.

Later in the afternoon. Elsa was going over some documents. However, Anna burst through the doors, a look of terror on her face. 

"Elsa!"

"Anna? What is it?" Elsa asked.

"It's horrible! Our friends...they're outside, fighting each other!"

Elsa's face was covered in shock. 

"We have to do something! Before they hurt themselves!" the ice queen's sister added.

"Show me," Elsa instructed. 

The two burst into a run, with Anna leading the way.

When they got outside in the courtyard, it was what Anna said it was. The Turtles were fighting each other, with their weapons too.

Leo was facing Raph. His swords collided with Raph's sai in a heated duel. They each blocked their attacks, and no damage had thankfully been inflicted upon either of them, yet.

Donnie was fighting Mikey. Donnie was mostly using his staff to defend against Mikey's constant volley of attacks from his nunchucks.

Raph kicked Leo back a few feet away, and Donnie did the same with Mikey. Donnie and Raph stood next to each other, paralleling Leo and Mikey by staring the other down. They then charged in ready to resume their fight. But the next thing they knew, a massive ice spike shot up from the ground separating them. 

Startled at the mysterious construct in front of them, they then turned to the not-so-mysterious user.

"Um, Elsa, do you mind?" Raph said.

"What is going on?!" she exclaimed, "Why are you fighting?!"

"We're not fighting, we're sparring," Leo corrected.

"'Sparring'?" a confused Elsa questioned.

"I saw you guys trying to hurt each other!" Anna added.

Donnie gave a light laugh at this, "No one was hurting anyone."

"Yeah! No harm among bros!" Mikey added.

"This is how we stay in shape, sharpening our skills so we don't grow dull," Leo explained.

"So, you were practicing?" Elsa clarified.

"Bingo, sister," Raph congratulated.

"I'm so, so, so sorry!" Anna apologized.

"We're sorry," Elsa added, "We didn't know."

Leo gave a reassuring smile, "It's nothing forget about it."

"Yeah, the worst we get out of this are a few cuts and bruises, nothing major," Donnie explained.

Elsa used her powers to withdraw the ice spike, "Well, please continue."

"Can we watch?" Anna asked.

"Sure," Leo said, "But, just keep a bit of a safe distance."

The Turtles had resumed their sparring. Elsa and Anna sat on the steps leading to the main door to the castle. Kristoff, Olaf, and Sven soon joined them as well.

Leo was now facing Donnie. The staff collided with the blade as the two fought. Donnie tried to get a few hits in, but all his attacks were blocked by Leo's blades. The blue-clad turtle tried to attack as well but got the same results. The purple-clad turtle made the first mistake, leaving his right side vulnerable with a swing. Seeing the opportunity, Leo sideswiped Donnie's right foot knocking him to the ground. Leo pointed his blade at him. Donnie dropped the staff, signaling his defeat. Leo smiled as he helped his brother to his feet.

At the same time, Raph was facing Mikey. Raph tried to strike with his sai, but all Mikey did was flip around him and dodge any attack. Having enough of the orange-clad turtle not fighting back, the red-clad turtle jumped and lunged his sai at him. Mikey wrapped one of his nunchucks around Raph's hands as he came down, and in one swift motion, threw him into the fountain.

"Aw yeah, son!" Mikey exclaimed, claiming victory while doing a robot dance, "You just got played like a baritone!" 

Raph lunged out of the water and put Mikey in a headlock, "Say it!" 

Mikey, rolling his eyes, grunted as he spoke, "Raphael is all-wise and powerful."

Raph then twisted Mikey's head a little bit, "And…?"

"And he's better than me in every possible way."

Raph then put Mikey to the ground, with a growing, sinister smile, "And…?" 

"And I'm a lonely worm who isn't fit to live on the same planet as him because he's so amazing and I'm a dirt clod," Mikey rolled his eyes again.

Raph licked his finger, prepared to give a Wet-Willie, "And…?" 

"In the history of the universe, there's never been one so awesome!"

Raph let him go, "And don't you forget it."

The whole event had been caught by everyone else.

"Are they always like this?" Elsa asked Leo.

"No. They're usually more annoying," he admitted.

Elsa and Anna both giggled a bit. Both of them were wondering the same thing. 

Is this what it's like to have brothers?

Chapter Text

Donnie had been walking through the halls, with Kristoff giving him a tour of the castle and Sven trailing behind him.

"This is a big place," Donnie observed, "And to think those two just spent their lives inside."

"I know," Kristoff replied, looking down for a bit, "It must have been hard on them, Anna especially."

Donnie knowingly grinned, taking notice of this, "So, you and the princess, eh?"

"Is it really that obvious?"

"Yeah pretty much. Seen the way she looks at you and you look at her. I had that look on my face a couple of times."

"What, you have a girlfriend?"

"Well…" Donnie rubbed the back of his head, "More or less. It's a little complicated."

"So what's her name, eh?" Kristoff lightly elbows him with a smug grin, with Sven grinning as well.

"Her name's April," Donnie answered, "Like I said though it's complicated. We saved her life one time. But she's human." 

He looked down, not willing to tell the whole 'part-alien, part-human thing, "I'm a mutant, I'm just…. What if I'm not cut out for her?"

Kristoff patted Donnie on his back, "Hang in there buddy. The best things in life are often what you wait for the longest."

Donnie smiled, "You sound like my sensei."

"I would love to meet him. He sounds like a great guy, rat, mutant, you know what I mean," the mountaineer didn't want to take it the wrong way, so he looked for a new conversation starter, "So, you fight with a stick?"

"It's called a Bo staff," Donnie corrected, "And it's a lot more useful than you think." 

He drew his staff, "Watch this." 

The Ninja Turtle began twirling his staff, jabbing it in the air, followed by a block, a step, a sweep, a twirl, a backflip, and a strike before exclaiming, "Strike!"

Kristoff's eyes widened a bit, "Wow. I guess a stick can be useful."

"With proper training, and a great mind to back it up," Donnie taps his head, "All the ninja needs is just his wits and a stick. What about you? You got anything?"

"Well, I may not be able to pull off any 'ninja tricks' or anything. But I can hold my own in a fight. As for a weapon, I just make do with what I got." 

He took a hatchet, which he just happened to have on him, and threw it across the hall. The blade landed right on a knight's armor, specifically on the helmet.

"Okay, not bad," Donnie congratulated as Kristoff pulled the hatchet out of the helmet and put it back in his strap. 

Donnie took notice of the deer, "So, how long have you had Sven?"

"Sven and I have been together since we were little. For the most part, it's just been me and him. But we were adopted." 

Kristoff laughed for a bit, "You think your family is weird? Wait till you meet mine."

Donnie laughed a bit too, "Family drives you crazy?"

"Yeah, a little. But they're pretty cool. They've been pretty helpful, especially if we have to deal with Elsa's magic."

"Yeah her, 'magic'."

"What does that mean?"

"Come on. Magic's not real."

"What do you mean? Of course, it's real."

"Magic's just a name for a type of science we don't yet understand."

"Then how do you explain Elsa's powers? She set her kingdom into an eternal winter for crying out loud! Plus Anna's heart, her sacrifice, and how that helped thaw it out, remember?" 

"As I said, it's a name for something we don't yet understand fully."

Kristoff sighed a bit, not wanting to start a fight or anything, "Why don't we just agree to disagree and leave it at that okay?"

"Works for me," Donnie replied. He didn't want to ruin any chances of making some new friends. 

They both continued down the hall.

Meanwhile, in the gardens, Anna was showing him around. Mikey looked around with his eager and pleasing demeanor, he had never seen more green and beauty in his life. Of course, being that he's lived in a New York City sewer all his life.

A couple of ducklings came walking by. 

"Aww. You guys are so cute," Mikey said as he crouched down and gently pet them. They began to chirp happily as he did.

Anna smiled at this, "You do love animals, Michelangelo."

"Call me Mikey," he reminded.

"Okay 'Mikey'. So what's it like being you?"

"It's awesome! Beating up bad guys, saving lives, making friends, games, food! Man, I love being a Turtle!"

"I may know you for only a short time, but I already envy you."

"Why would you envy me?" a confused Mikey asked, "I mean look at you. Your castle's awesome, you have a great kingdom, you're royalty, and your sister has the coolest powers I've ever seen! Do you like what I did there? 'Cool' as in 'ice'?"

Anna giggled a bit, "Yeah. But you should have seen what it was like most of my life." 

The ice queen's sister's smile slowly fades, "Elsa and I were close when we were little, then she just shut me out." 

Mikey's smile faded a bit too.

"I understand why she did it. I do. But, all those years apart, we had our parents, but after they died…." 

She took a deep breath, "We were all we had left. That was when we...I, was the most alone." 

She looked down a bit, eyes closed and her back turned to Mikey. 

Mikey put his hand on her shoulder, getting her attention, "Hey, at least things worked out right? Better late than never." 

Anna turned to him at that, "Besides you got Kristoff and Olaf. Just remember this: family's like melted cheese, it sticks together. Like me, my bros, my sis, and my sensei."

She smiled and soon embraced Mikey in a hug. Surprised a bit at first, Mikey soon returned the hug. After about a minute of hugging Anna pulled away. 

"Thanks, Mikey."

"No problemo."

Something soon came to Anna's mind, "Wait, you four have a sister?!"

"It's a little complicated," Mikey looked down for a minute.

Anna could tell this seemed a bit too personal to him, so she changed the subject, "So, what do you think of Arendelle?"

"It's awesome!" Mikey returned his smile, "So, where's the nearest pizza joint?"

"What's pizza?"

"What?!" Mikey shouted with wide eyes. 

He grabbed her shoulders and looked a little panicky, "You know, pizza. Crust, tomato sauce, cheese. It delivers?!"

"No, never heard of it. I guess we don't have that." 

Mikey just let go and stood with a blank stare, "Umm...Mikey? Are you okay?"

Mikey fell to his knees, clutched his head, and shouted to the heavens, "NOOOOOOOOOOO!!!"

Soon a pebble was thrown and hit him square in the head. 

"SHUT UP MIKEY! I'm trying to take a nap!" 

The two turned to Raph who was sleeping in a hammock on the other side of the garden.

"Dude, Raph! There's no pizza here!" Mikey shouted. Raph was on the other side of the garden, which was pretty long, so shouting was the only way to be heard.

"I don't care!" Raph shouted back, "I'm trying to get some sleep!"

"What's pizza?" Anna shouted, "Is it important or something?!"

"NO! It's just food where we come from!" Raph shouted back, "Mikey's being overdramatic as usual! Do you mind?" 

He shouted as turned in the hammock trying to get some shut-eye.

Anna helped Mikey to his feet, "Is he always like this?"

"Yeah," Mikey admitted, "He has anger issues. And I mean  major  anger issues."

"He seems like a bit of a jerk." 

"Sister, I can tell you stories. But he's a good guy, just can't control his temper."

Anna noticed something behind Mikey, which made her smile. The orange-clad Turtle turned to see what she was looking at. It was Olaf chasing a butterfly.

"Butterfly, get back here," Olaf said joyfully as he chased it. 

He soon noticed the two, "Oh, Hi Anna, Hi Mikey."

"Hi Olaf," Anna greeted back.

"What are you doing?" Mikey asked casually.

"Chasing my butterfly," he then began to look around, "Now, where is… Oh, there's Raph." 

He soon noticed Raph sleeping in his hammock on the other side of the garden, "I think he could use a hug."

Anna soon stopped him, "I don't think that's a good idea, Olaf."

"Yeah dude," Mikey added, "Raph's not a hugger."

"He doesn't hug?" Olaf said in disbelief. "Everyone needs a hug!"

Mikey was about to say something but Olaf gasped, "I bet that's why he's angry. No one's ever hugged him." 

Olaf gasped again, "He needs an emergency hug!" 

The snowman declared running in the direction the sleeping Raph was before Mikey or Anna could stop him.

Anna turned to Mikey, but he soon closed his eyes. 

"Three, two, one," the orange-clad Turtle said.

Right before they heard Raph scream at the top of his lungs, Anna plugged her ears.

"Heads up!" they heard Olaf say as his head came flying in their direction. It smacked into the wall and stuck to it. 

"Watch out for my butt!" he added as the rest of his body was sent flying and stuck to the wall before it all fell to the ground.

Anna turned to Raph, "It is not nice to throw people!"

"That thing woke me up! I specifically asked NOT to be woken up!" he argued as he walked closer to them. Mikey helped put Olaf back together as they argued.

"He was trying to be friendly!" Anna defended her snowman friend.

"Well, have him be friendly, away from me!" Raph demanded.

"It's not his fault you have anger issues!" the royal argued.

"Oh, you do NOT want to go there, sister!" the red-clad Turtle argued.

Olaf was put back together, "Did I make you angry? I'm sorry, let me give an 'I'm sorry'-hug." 

He hugged Raph's leg. Startled, the hot-headed Turtle soon stumbled backward and fell into a pond, accidentally kicking Olaf to the other side. Raph soon arose dripping, and Mikey sensed what was coming. 

"Uh oh. He's awoken the beast," Mikey warned.

Raph turned to Olaf, growling, with his eyes practically on fire. 

Despite that Olaf still had a smile practically glued to his face, "You're still angry? Maybe you need another hug?"

That tore it. Raph turned to Mikey and Anna with a fake smile, "Okay Mikey, you'll  love  this show…" 

He turned back to Olaf, and his fake smile faded while cracking his knuckles, "…It's called 'Does Olaf Bend That Way?'"

Olaf, acting on new instinct ran away, with Raph chasing him. 

"COME HERE YOU!" he shouted as he leaped toward Olaf. 

Mikey and Anna ran toward the sound of screaming and snow scraping, hoping to stop the conflict.

Meanwhile, Elsa was on the highest balcony of her castle from her room. She was looking out to the kingdom, watching the sunset.

"What are you doing out here by yourself?" 

She heard a voice from above, and turned and saw Leo. He lept from the roof and to the balcony next to her.

"Hello, Leonardo," Elsa greeted.

"Just call me Leo. Only my sensei calls me 'Leonardo', your majesty," Leo replied.

"Well 'Leo', my friends just call me Elsa."

"Okay, 'Elsa', so what are you doing out here alone?"

The ice queen's gaze turned back to the Kingdom. Leo looked at the view too, with the sunset giving the atmosphere a new sense of majesty. 

"That's one heck of a view," Leo said.

"Yes, quite beautiful," Elsa replied, her smile fading a bit. 

Leo caught notice of that, "Hey, you okay?"

"Yes, I'm fine," Elsa replied, bluffing a little bit.

"You seem a little worried though," Leo recognized that look of concern on her face. He'd seen it on his face quite a few times.

"I guess I do," she sighed, not knowing how to finish, "I guess, I'm just a little…." 

"A little worried?"

The ice queen looked down a bit. 

"I know exactly how you feel." 

Elsa turned to Leo with a bit of surprise.

"Excuse me?"

"Granted, I don't have special powers or anything," Leo admitted, "But I know how you feel. You're the Queen of this place. You're the leader. You have a responsibility. But you worry. You worry you make a decision and it turns out to be the wrong one. You fear that mistake will let the people you're leading down, and it may end up getting them hurt or worse. Especially if it's a friend, or family, someone close."

Elsa looked at the Turtle with surprise. That was exactly how she felt, "How did you…?"

"Because it's the same kind of thing with me."

"What do you mean?"

This time, it was Leo's turn to sigh, "You remember how we told you and Anna about some of our adventures?" 

Elsa nodded. 

"Well, it's not as fun as it all sounds. The situations my brothers and I face are life and death. The enemies we fight are dangerous. Some of them are ruthless and have made it their goal to snuff us out."

Elsa was getting a bad feeling about where Leo was going.

"I'm the leader. I make the decisions. And every time we go out, I try and act confident, like I know what I'm doing. It's true sometimes, but other times, I only act that way so that others are willing to follow me. I never told anyone this, only Master Splinter, but…when we go out on a mission. I get scared."

"'Scared'?" Elsa asked in disbelief, "You?"

"Yeah," Leo answered, "I'm scared that I make the wrong decision, and that it might hurt my brothers, or worse, end up getting them killed."

"But, I saw what you four are capable of. You took down over a dozen professional assassins and mercenaries."

"To be honest Elsa, those guys are only decent workouts compared to what we face."

Elsa's eyes widened.

"Every time we go out, we face things you wouldn't believe. Things that seem impossible to beat. But we have to fight on. We have to push forward and face it."

"Your right about one thing. I am scared. I'm scared that my powers, or a decision I make, can lead to someone getting hurt. My powers, the responsibility, and on top of that, being the Queen... it terrifies me. When I froze my kingdom and froze Anna's heart, I was scared beyond belief."

She was starting to get worked up. From her hands on the balcony's railing, frost began to form, "When I thought that I…. seeing her, completely frozen…I just…." 

She couldn't finish. Tears began streaming from her eyes.

Leo looked at her with a great feeling of sympathy and empathy. He put her hand on her shoulder, "I understand. I do."

"How do you do it though?" Elsa teared up, "How do you, not be afraid? How do you keep going and not feel fear?"

"You don't. You can't be fearless, it's impossible."

"I don't understand,"

"Fear is natural. Everyone experiences it. But the trick is not being fearless; it's about having fear and overcoming it. To beat fear, you don't try and avoid it, because it will catch up to you. To beat it, you face it head-on. All fear is, is just an obstacle, and once you overcome it, there is nothing you can't do."

Elsa whipped her tears away and a smile formed. She had developed a great sense of respect for this Turtle, "You are very wise Leo."

Leo smiled, "Thanks but, I can't take all the credit. This was the most important lesson Splinter ever taught me, about being a leader."

"Your Master is a wise man," Elsa said, "…or rat or… you know what I mean."

Leo laughed lightly as he went inside, "You really should meet him. I better go make sure the guys are staying out of trouble."

Right when he got to the door... 

"Hey, Leo?" Elsa called out. 

Leo turned to the smiling Ice Queen. 

"Thank you."

"Hey, what are friends for?" Leo replied with a warm smile as he left the room.

Elsa then looked out to the setting sun.

Night had fallen. It was pitch black, save for the dim moonlight. In a dark room, from a table, sat Hans. The man who sat across from him was the Duke of Weselton and his two guards.

A wooden door entered and walked in a large man with a long black beard. He wore an eye patch and black mercenary garb, much like the dozens of assassins from earlier. He had a black cape, and a white sword painted across his chest, with a skull at the tip of the blade.

"I trust your men have succeeded?" the Duke asked the man.

"I'm afraid not. They have yet to return, which leads me to believe they have been captured or are dead," the man responded.

The Duke slammed his tiny, elderly, fists on the table. Hans kept a calm demeanor, but he was most infuriated. 

He inhaled deeply as he spoke, "Dregg, Are you and your men not the 'fiercest mercenaries of the world'?"

The man, whose name is Dregg, replied, "I assure you, Hans, we are every bit as fiercest. We have never dealt someone with strong magic before."

"Then what do you plan to do then?" the duke asked.

"I'm sending my best man," the mercenary replied, "He'll get it done."

"Dregg, if a dozen men failed, what makes you think  one  is capable?" Hans asked.

"Unlike the last attempt which was a direct assassination, this one specializes in the quiet form," Dregg began, "My man is the master of the silent kill. He specializes in snakes and all forms of their venom. He has never failed."

"Perhaps this will work," the old duke mused to Hans.

"Alright. Send this man. See to it that he kills Elsa and brings me proof of it. Also, bring Princess Anna, alive," Hans instructed.

"Why would you want her alive?" Dregg asked.

"I have my reasons," Hans stated plainly.

Chapter Text

The Turtles and the royal sisters were just finishing up their dinner in the dining hall. When the maids came to collect their dishes, some tried to avoid any possible eye contact with the turtles. Elsa and the Turtles noticed this as well. Many of the servants were acting the same way. The only reason they didn't freak out and start a panic was that Elsa told them they were friendly, but that didn't stop them from staring.

As they were walking down the halls, Elsa spoke, "Guys, I'm sorry about dinner."

"What are you talking about?" Raph asked, "Dinner was great."

"No. It's about the way all the servants acted," Elsa corrected.

"Oh, that," Mikey said, partially looking down.

"Don't worry about it, it's not the worst reaction we got," Donnie added.

"Yeah," Leo said, "We find that people treat us better when they don't know we exist."

"That's not fair!" Anna exclaimed, "You're good guys. You've done nothing to hurt us or anyone."

"That's just the way things work with us," Donnie replied, "Most of the people we've met only see the exterior and make judgments only on what they see."

"Don't you ever get tired of that?" Elsa asked.

"After fifteen years, we've gotten used to it," Leo said.

Elsa felt a sense of familiarity with that. She had been in a very similar situation.

"I'm sure if people just got to know you…" Anna began.

"We're more likely to be run out of town by an angry mob," Raph interrupted

"What Raph is trying to say is..." the leader began, "We can't change what people think of us. You don't always get what you want."

"I'm sorry about that," Elsa apologized, "I am."

Soon, Elsa and Anna left for their rooms to go to sleep. The Turtles would stay up for a little while longer.

Anna got into her nightgown and was about to sleep. She began to feel sorry for the turtles. They were good people and should not be treated like monsters. As she began to sleep, she wondered what she could do to help.

Elsa was going to bed as well. She could identify with the Turtles. Though she felt sorry for them, it also felt a little nice to see other people could understand her. She felt that was a bit of a guilty pleasure. She then fell asleep.

Outside the castle, a slim man in black garb and a thick belt quietly moved through the water below. He moved like an eel through the night. He slowly and quietly climbed the wall from the water and into the courtyard, carrying a long, thin glass container with him. A sound could be heard from the container. He began to stroke it.

"Patience, my friend," he lulled, "Your time will come shortly, I promise."

He then quickly and silently got to the castle wall, then climbed it.

Meanwhile, in the castle, the Turtles were in the hallway near Elsa's room.

Donnie was looking at some of the paintings and sculptures, "Look at all this. Such detail."

"Yo bros!" Mikey shouted, "Check this out!" 

Mikey was juggling three busts, and riding a certain bicycle in a circle.

"Put those down for you break something!" Raph exclaimed.

The orange-clad Turtle tripped on the bike and the busts went flying through the air. Donnie and Raph were able to catch them right before they hit the ground. The three breathed a sigh of relief. Donnie and Raph put them back, Raph then went into Mikey's face.

"And that's why you don't touch anything!" he exclaimed, "Right, Leo?"

Leo didn't answer for he was looking out the window and seemed to be brooding a bit.

"What's eating you  this  time?" Raph asked.

"It's Elsa," Leo answered.

"What are you being so upset for? She's great," Donnie said.

"Yeah, man!" Mikey agreed, "This castle is awesome! Her sister is awesome! And she has superpowers!"

"I know," Leo replied, "But still, think of what she went through because of those powers."

The Turtles' expressions dimmed.

"Being told her powers were dangerous, isolating herself, even from her own family... being afraid all her life," Leo listed, "No one should ever have to go through all that."

"Yeah and soon, people called her 'monster'," Mikey added, "She froze Anna's heart, and…" 

Only for Raph and Donnie to glare at him, shutting him up.

All the while, the slim man was crawling along the roof, not making a single sound. He saw a window and looked into it like a bat. He saw the sleeping queen, an evil smile forming on his face.

Back in the hallway... 

"I just, wish there was some way we can help her," Leo said.

"Look, Leo," Donnie began, "She'll be alright."

"Yeah, dude. She seems happy," Mikey said.

"I know, she is," Leo replied, "But I still see some fear in her eyes. It's like a parasite, clinging to her and not letting go."

Outside, the slim man set foot on the balcony. He took out a small blade and cut a hole in the glass door at the bottom.

"What are you gonna do?" Raph asked, "I mean it's not like you have elemental powers or anything."

"I know," Leo admitted, "But I can help. Maybe teach her to meditate. That always helps."

The slim man reached for his container, opened it, and put it in the hole. A snake slithered out of it and into Elsa's room.

"Meditation could be useful," Donnie thought.

"Eh, I'd just go with it," Mikey mused.

"We're not talking about you," Raph said, "Look, why are you so interested in helping her?"

The snake slithered quietly across Elsa's room. Hissing a bit, but the sleeping Elsa didn't seem to notice. It made it to her bed.

"She's a person in pain Raph," Leo argued, "I can't just ignore that."

The snake slithered up and onto Elsa's bed.

"Leo…" Raph began. 

Right as he said that, Leo thought he heard something.

"Shhh," Leo shushed.

"Did you just…" Raph began, getting a little irritated.

"Raph, be quiet!" the blue-clad Turtle gritted through his teeth, "Listen."

The turtles were silent, trying to hear whatever it was that caught Leo's attention. They remembered a lesson Splinter taught them when they were young. His words ran through their minds. 

Listen to the silence, my sons. Listen deeply . 

Their audio senses picked up a hissing sound: the kind of hissing a snake makes. It was coming from Elsa's room, to which they turned to each other with worried looks.

The snake was right on top of Elsa. It lifted its head and opened its mouth, revealing its fangs. The man smiled from the window.

Then, in a flash...

Leo burst into the room. He leaped, drew his katana, landed on Elsa's bed, and decapitated the snake.

Elsa had suddenly awakened. She saw Leo on top of the bed and the headless body of a snake right next to her. 

He just saved her life again.

Leo looked out the window and saw the slim man. 

The assassin's cover had been blown. He quickly climbed to the roof, right as Leo broke through the window doors. Leo turned and saw the man just made it to the roof, Leo jumped after him.

Elsa had to collect her thoughts. Just sitting on her bed, she failed to notice Anna running into her room.

"Elsa!" Anna exclaimed, putting a hand on her shoulder, startling her a bit, "Are you alright?"

Leo had jumped onto the roof and was pursuing the assassin. The assassin was just about to get to the other side when Raph jumped up from another balcony and landed in front of him, his sai at the ready. He looked and saw Leo behind him, who drew his katana blades. He was about to run to his left and saw Mikey flashing his nunchucks. He looked to his right and saw Donnie with his Bo staff. He was surrounded.

Getting desperate, the slim assassin broke into a run toward Donnie. He pressed his hands on Mikey's shell, shoving the turtle to the roof and jumping over him. He jumped over the roof's edge and was falling into the water below.

Before he could reach the water, however, Mikey extended his nunchuck chain and it wrapped around the assassin's legs. The Turtle then swung him into a window.

The man rolled to a stop in the hallway. He got up and ran down the hall, he stopped a few feet and saw six guards coming at him and aiming their crossbows.

He turned around and saw the Turtles leap from the broken window and land in front of him, weapons at the ready. He was, once again, surrounded.

Leo pointed his blade at him, "Who are you?"

"You'll get nothing from me!" the man replied. 

He took out a dart from his belt and jammed it into his leg.

The man fell to the ground, twitching in all forms possible. The guards and Turtles all ran to him. Elsa and Anna had made it to the scene to see what was happening.

The man twitched even more, and foam formed at his mouth until finally, he stopped moving altogether. Leo crouched down and checked for a pulse; nothing. 

Leo shook his head, "He's dead."

Anna covered her mouth at that revelation.

Donnie took the dart from the man's leg and sniffed it. He gained a curious look, "Smell this." 

Mikey took a whiff of the needle and went coughing and gagging, but not to the point of vomiting. 

"Nasty isn't it?" Donnie said, "This is lethal venom from the blue krait, one of the world's most poisonous snakes."

"Um, guys?" Raph began. 

He took the belt off, and it had dozens of darts in it. The guards, turtles, and sisters looked in surprise, for this guy was a professional.

The guards took his body and left, leaving the Turtles and sisters alone.

"You alright?" Leo asked Elsa, to which she nodded much to his relief.

"Hey guys, what happened?" 

They heard Olaf say as he walked in, and everyone, even Anna, ignored him.

"At least it's over, right?" Anna asked.

"I'm not so sure," Leo replied.

"That was two attempts to kill you," Raph said to Elsa.

"Plus that guy wore the same garb as all those men from the ball," Donnie added.

"You think they're connected?" Elsa asked.

"They're correlated," Leo replied, "Somebody wants you dead."

Elsa had to, once again, collect her thoughts. She had been targeted for assassination. 

Anna put her arm around her sister.

"Who would want to kill my sister?!" Anna exclaimed, "She has done nothing wrong!"

"Ha!" Mikey exclaimed, "I know exactly who's behind this!"

"You had better not say 'squirrels with lasers' again!" Raph warned, to which Mikey looked down.

"I know how we can find out," Leo said.

"You want to interrogate the prisoners?" one of the guards asked. 

They were at the door leading to the dungeon. The Turtles, sisters, and Kristoff were all there. Kristoff, being the princess' lover, wanted to be a part of this as well.

"Not all of them, just one," Donnie said.

"We've tried everything, but they've refused to talk," the guard replied.

"They haven't met us before," Raph said, cracking his knuckles, "We won't get them to talk. We'll get them to sing."

"I'm not sure I should let you in."

"Your queen has been targeted for assassination," Leo reminded, "We can find out who sent them and stop whoever's behind this."

"I'm not sure if…"

"Please!" Anna begged, "I don't want to lose my sister again."

"It's alright," Elsa assured, "You can trust them."

The guard exhaled deeply. He unlocked the door and opened it, "Good luck."

One of the mercenaries from the ball awoke to a startling sight. He was strapped to a chair, with an empty table in front of him, and two bright torches were off the sides. Mirrors behind him direct their light to his face like a lamp.

His eyes had just finished adjusting to the sudden brightness, "Where am I?"

He saw a figure with his back turned on the other side of the desk. He turned to the mercenary. It was Mikey, wearing a pair of sunglasses. 

"I'll ask the questions here, see?" Mikey began, acting like someone from a cop show, "Tell me who are you and who you work for, see?"

"You think I'm gonna crack, freak?" he glared at the turtle, "Forget it! My lips are sealed!"

The orange-clad Turtle leaped to the other side of the table and slapped the man across the face. 

"You're gonna talk," Mikey stated calmly, "Now let's try this one more time. Who are you guys?"

"The guards already tried scaring me, demon," the mercenary said, "I'm not saying a word."

"Tough guy, huh?" he heard a voice say. 

The man turned and saw Raph, not donning sunglasses like his brother, leaning against the wall carrying something.

"Let me try, Mikey," Raph proposed. 

Mikey backed off, still with the cop persona.

"You see this?" Raph said, holding up a familiar belt, which made the mercenary gasp, "I got this from your snake friend after he killed himself, that is."

"You…you got… him?"

"Yep," Raph said, "He nailed himself with one of these darts. Now, we're gonna play a little game I like to call 'poison roulette'. You see I have no clue what's in these darts." 

Raph said as he took one out, with a sinister smile forming, "Why don't we find out?"

"You're not gonna…?"

"Now, best case scenario, it's just a mild tranquilizer and it'll give you a little nap." Raph said, " Worst case  scenario, it's a deadly poison that will lead to a slow, agonizing death." 

The man gulped, "It could, and it couldn't. That's the thing with roulette, you never know what you're gonna get."

"You wouldn't."

"Try me," Raph warned. Though he had a mischievous smile, his eyes told the man this turtle was very serious.

"Okay! OKAY! I'll talk! I'LL TALK!"

Raph withdrew the dart and he and Mikey were listening.

"Alright," the man began, "We are called 'The Night Blade', and we work in the shadows. If someone wants something stolen, we'll get it. They want someone kidnapped, we'll grab 'em. If you want an assassination, that person's as good as dead. The bigger the target, the higher we charge."

"Who's in charge of you guys?" Raph asked.

"Our leader's name is Dregg. He is the strongest among us. He meets the one who pays us and tells us our target."

"Dregg's the head of the Night Blade?" Mikey asked for clarification.

"Yes."

"Then I will call him 'Head Blade'!" Mikey announced with pride, to which Raph rolled his eyes.

"But his name is Dregg."

"Enough!" Mikey shouted as he backslapped the man.

"Who hired Head Blade to kill Elsa?" Mikey asked.

"I can't say."

"Now, why's that?" Raph asked.

"It's our solemn vow. We never spill the beans on who pays us."

To this, Raph brandished dozens of darts from the belt, which made the man wet his pants. 

"But…As long as you don't  say  I told you…"

Raph smiled at this.

After about ten minutes, Leo, Donnie, Elsa, Anna, Kristoff, and Olaf had been waiting in the throne room. Raph and Mikey then walked in.

"Well...?" Leo asked.

"He sang," Raph said with pride, with Mikey putting his sunglasses away. 

Everyone, minus Olaf who couldn't understand the situation, was paying attention.

"They call themselves the Night Blade," the red-clad interrogator began.

"I've heard of them," Kristoff stated, "Professional killers, thieves, and kidnappers."

"Yeah, pretty much," Mikey said.

"What else did you find out?" Elsa asked.

"They operate in a ship that's outside the harbor. It keeps moving to prevent anyone from getting suspicious."

"Then how do they pick up their men?" Donnie asked.

"They send a messenger bird to their ship telling them to pick them up, once they finished their job."

"None of them had a bird with them," Anna remembered.

"He's over there," Mikey pointed to the corner.

They saw a black hawk in a bird cage that the two turtles just caught.

"He's been hiding on the castle's roof," Raph said, "It wasn't that hard to catch him."

"If they're mercenaries, then someone must have hired them," Donnie theorized.

"Someone did," Mikey replied.

"Did you find out who?" Leo asked.

"We did," Raph replied, "Two guys, one of whom was some Duke of this weird country called, 'Weaseltown'!"

"Weselton," Elsa corrected.

"You know him?" Mikey asked.

"Yes," Elsa answered, "He was once our trading partner, but only did it for his benefit. After the incident where I froze my kingdom, he sent two men to kill me."

The turtles looked interested at this point.

"Afterwards, he was escorted out of Arendelle, and we stopped all interactions with his country."

"Looks like he didn't handle that very well," Leo commented.

"He was the one who labeled Elsa as a monster," Anna reminisced.

That made Leo angry, and his brothers irritated. 

"What a jerk," Mikey commented.

"But who's the other guy?" Kristoff asked.

"Some dude named 'Hans'," Mikey replied.

Elsa, Anna, and Kristoff all looked at each other in shock.

"You know him too?" Donnie asked.

"Unfortunately," Kristoff replied.

"What did you do to get him mad?" Raph asked.

"That's... a little more complicated," Anna admitted.

Chapter Text

"So, who's this Hans guy?" Leo asked.

Elsa, Anna, and Kristoff had to give it a moment. They did not like talking about him. Olaf was present as well but wasn't paying attention. 

Anna was the first to speak, "Well…the thing is...he and I were engaged."

That got all the Turtles' attention.

"He came to Arendelle on the day of Elsa's coronation," Anna told, "He seemed like a nice guy. But when the kingdom was frozen, he showed us his true colors. All he wanted was Arendelle. He would marry me and stage Elsa's death as an accident…"

"Which would make him king," Leo finished.

"Talk about a spoiled kid," Raph commented.

"To get you to trust him enough to want to marry him..." Donnie reasoned, "You must have known him for years."

"Well, not really."

"Huh?" the Turtles all replied.

"I got engaged to him, but I also just met him that day. So anyway…"

"Wait," Leo interrupted, "You got engaged to a guy you just met that day?"

"Yeah. As I said, he seemed nice at first but…"

"Whoa, whoa, whoa! Hang on!" Leo interrupted again, "You got  engaged  to a guy you just met  that day ?!"

"Yes. Can I please continue?"

"No!" Raph replied, "You can't just say 'you got hitched to a stranger' and expect us to just ignore it! You guys heard that right?"

"I heard it," Donnie answered, "I'm still working on believing it."

"Seriously dudes, even  I  know that's wrong," Mikey stated in a deadpan way.

"I have to agree," Leo began, "I mean, just asking them on a date or kissing them is one thing. But marriage?! What were you thinking?!"

"I was thinking it was an act of true love."

The Turtles all looked at each other for a brief moment, before they all burst into a fit of laughter. Anna looked in surprise at the Turtles laughing. Elsa and Kristoff glared at them a bit as they continued to laugh. Mikey fell to the ground laughing, while the others were supporting themselves on their knees as they continued laughing.

"What?!" Anna asked, "What's so funny?!"

The Turtles slowly rose and their laughing was stifled. Mikey snickered a bit more.

"That's not true love, Anna," Leo resumed the discussion's seriousness, "That's just being desperate."

"Desperate?"

"Yeah, sister," Raph said, "Desperate."

"Look," Kristoff interrupted, "She made a little mistake."

"'Little'?" Donnie asked.

"Okay, a  big  mistake," Kristoff corrected, "But she did learn her lesson, the hard way."

"She has," Elsa agreed, "So would you please just listen? This is not a topic we like to discuss."

The Turtles, even Raph, had a brief sweep of guilt sweep over them.

"You're right," Donnie replied.

"Sorry, Anna," Mikey apologized.

"Yeah, we are," Leo added, "Please continue."

"But  I'm  not dropping this," Raph stated.

Despite all that, they told the story. Anna told them how Hans was able to fool her, and how that proposal is what lead to Elsa freezing Arendelle, and running away. Anna also told how, as she was dying, Hans revealed himself and left her for dead. That made the reptiles, especially Mikey, irritated. Even during the worst of that crisis, Hans told Elsa she had killed her sister and was going to kill the queen in her sorrow. That made Leo angry, clenching his fists tight in contempt. When they finished, they awaited the Turtles' responses.

"I come from the sewer," Donnie began, "But  that  is low."

"What a dirtbag," Mikey reacted, "Guys like him make me sick."

"I haven't even met him," Raph stated, "But I already know that he needs a beat down."

"For once Raph, I completely agree with you," Leo complied, "That guy needs a beat down."

"What are we gonna do?" Elsa asked.

"We'll take care of him," Raph replied.

The humans' eyes went wide.

"Really?" Anna asked, "Just like that?"

"Yeah, we deal with jerks all the time," Mikey said.

"We'd be more than happy to get him off your backs," Donnie added.

"Don't worry, Elsa," the leading Turtle reassured, "We'll make sure Hans doesn't bother you guys again."

"How are you even going to find him?" Kristoff asked, "Hans, the Duke, and the Night Blade are on a ship that's always moving. There's no way of knowing ahead of time where it's going to land."

"We'll think of something," Donnie said.

"You better think of something quick," Elsa urged, "I do not like being on a hit list."

"It's not just you," Mikey replied.

"What?" Elsa asked.

"That guy we talked to," the red-clad Turtle reminded, "He said their primary goal was to kill you and bring back proof. But, he said they had another goal." 

He pointed to Anna, "You."

"Me?!" the ice queen's sister asked, terrified, "Trying to kill me too?!"

"Not exactly," Mikey corrected, to which the three looked confused.

"They were also paid to bring you back to the ship alive," Raph relayed.

"Why would Hans want that?" the ice mountaineer wondered.

"From the story, you just told us," Leo began, "I'm guessing Hans wants to finish Anna off himself."

"Typical bad guy pride," Raph summed up.

"Proof of my death, my Sister in his hands," the ice queen surmised, gripping the arms of the throne causing frost to form underneath, "How are we gonna handle this?!" 

"Without more info, finding Hans will be next to impossible," Donnie said.

"Well, maybe we make  him  come to  us ," Mikey answered.

Everyone looked at Mikey as soon as he said that. 

"Dudes and dudettes!" the orange-clad Turtle exclaimed, having gained a eureka moment, "I have a plan."

"Okay, that scares me," was all that Leo could say at that moment.

It was just at the crack of dawn at the ship of the Night Blade. Hans was with the Duke at the table inside, waiting for a report. The Duke was sleeping and snoring rather loudly at the table. The duplicitous prince remained awake but was growing more and more impatient.

Dregg entered the room.

"Am I to assume your assassin has failed, Dregg?" Hans asked,

"To the contrary Hans," Dregg began with a smile, "The Black Hawk has returned and we have received confirmation. Queen Elsa is dead."

Hans looked in surprise at Dregg, the Duke waking up at that. 

"Wh….what? Elsa is dead?" he yawned, mind slowly catching up to him, "Elsa is... dead!"

Hans's shock turned into twisted satisfaction as he smiled.

"And even better, he freed some of our men from the dungeon, and they are returning with the Princess," Dregg continued.

His evil smile went from ear to ear, "Perfect."

Meanwhile down in the harbor. The sun was just beginning to rise. It revealed a row boat. There were six figures in it. Four were rowing the boat, and another was at the rudder behind, steering it. The five were wearing black cloaks and hoods, no one could see their faces.

The sixth figure in the boat was Anna. She had a bag over her head, hands tied behind her back, and a rope wrapped around her, binding her upper body and arms together.

The rowboat then stopped at the sight of an incoming ship. A rather large ship, at least twice the size of Arendelle's ships. It was black, including sails, save for the white symbol of a sword and a skull where the handle would be on the largest sail.

The four stopped rowing and the massive ship stopped, both boats were just inches from each other. A rope ladder was thrown down to the boat. The figure in the back grabbed the tied-up Anna and threw her over her shoulder. The five then climbed the latter and onto the boat.

They had climbed onto the boat and had seen at least two dozen killers on board. Some were working at the stations, and others were just minding their own business but stopped when they saw the five come up, with their captive.

They just stared at them until five men came from the door leading to the inside of the ship. It was Hans, Dregg, the Duke, and his two guards.

"What are you all looking at?" Dregg asked his men rudely, "Get back to work!"

They all resumed what they were doing.

"Where's Silith?" Dregg asked.

"And didn't we send a dozen of you?" the Duke tried to remember.

"Silith freed all of us," the hooded figure in front began, "Unfortunately, the guards tried to stop us from escaping. He didn't make it, and the same goes for the rest of them."

Dregg looked disappointed, "Silith is dead. He was my best guy. Ah well."

"On the plus side though," the hooded mercenary continued, "During the chaos, we killed the queen, and, as you can see, grabbed the princess."

"Not usually our style," Dregg criticized, "But at least the job was done."

"Where's the proof that Elsa is dead?" Hans asked.

Another hooded figure reached inside his robe and threw him an object, which he caught, "Does her blood-soaked crown count as enough proof for you?"

Hans looked at the object. It was indeed Elsa's crown. It was covered in streams of red liquid. 

The ex-prince once again smiled, "Yes, it does."

"Well then, Hans," the mercenary leader bargained, "We did our part. Now for our money."

"Nor just yet," Hans brushed off, "Put her down."

The largest one put Anna down from his shoulder and onto her knees. Hans approached and removed the bag. Anna was wide awake, with a piece of cloth covering her mouth. She looked at Hans with a hateful glare.

"I better you never thought you would see me again, huh Anna?" Hans asked.

Anna could only muffle through her gag.

"Nothing to say?" her former lover teased, "Well if it's alright with you, I'd like to get this over with." 

Hans then drew his sword, "Don't worry, look at it this way. Now you and your sister can be together, forever. In the afterlife that is."

He raised his sword and brought it down. Before it could make contact, however, it was blocked by another sword. Hans looked in surprise at the bearer of the opposing sword: one of the hooded figures, who had stepped in front of Anna. But this wasn't just a sword, but a katana.

The hooded figure then delivered a round-house kick, knocking Hans back into Dregg, the Duke, and his guards. All the men on the ship looked in shock at the scene.

Dregg was the first to get up, "What in the hell do you think you're doing?!"

"Saving a friend," the figure replied. 

He threw away his robe revealing Leonardo. Three more figures discarded their robes, revealing Raphael, Donatello, and Michelangelo. The last one lowered his hood, showing the face of Kristoff.

"WHAT IN THE WORLD!?" Hans shouted.

Leo smiled. Everything went according to plan.

Five hours ago

"Dudes and dudettes!" Mikey began, "I have a plan."

"Okay, that scares me," Leo replied.

"No dudes, listen," Mikey told, "Hans wants Elsa dead and proof her death, but he wants Anna alive."

"Where are you going with this?" Donnie asked.

Mikey continued, "We use that Black Hawk to send a fake message to the Night Blade ship, saying Elsa is dead and we have Anna. So, the four of us will wear those black robes those guys wore and go up in a boat with Anna. We can also cover Elsa's crown in red paint or something that looks like blood, as 'proof of her death'. The ship will come, and once we're on board, Hans will act like the big bad guy and gloat. And once he's out in the open, we take him down, along with that Duke guy, and the whole Night Blade. All while Elsa uses her ice powers to freeze the water around the ship to stop it from leaving."

All looked in surprise at Mikey.

"That's…" the blue-clad Turtle began, "That's a good idea."

"Yeah, it…it is," Donnie stuttered in surprise.

"It's, actually…" Raph stumbled, "...the best idea you've ever come up with."

"You guys always underestimate me," Mikey stated with pride, "Booya…Kasha!"

"Hold on!" Kristoff interrupted, "You're willing to risk Anna's life?"

"Look, Kristoff," Raph assured, "That's the only way the plan can work."

"Then I'm going with you," Kristoff said.

"Kristoff!" Anna exclaimed worriedly, not wanting to see someone she loved risk his life.

"If Hans is after you, I'm not letting you out of my sight," the mountaineer replied.

"You're coming with me no matter what, aren't you?" Anna asked as she sighed.

"Yep," he said.

"Alright then," Leo began, "We have our plan. Let's bring these guys down."

"Leo?" Elsa stood up and walked up to him, "Anna won't be hurt, right?"

"Don't worry," Leo reassured, "No one's gonna hurt her."

"You promise?" Elsa asked,

Leo smiled, "I promise."

Back on the ship

The entire ship was rocked and shaken. The Turtles, Kristoff, and Anna maintained their balance, but everyone else was rocked off their feet.

"What was that?!" the Duke shouted.

"Dregg!" one of the men from the sails on top shouted, getting his attention, "Ice has formed all around the ship! We can't move!"

"What!?" Dregg shouted.

Down below, ice was indeed forming around the massive ship. Elsa was on a thick, solid, patch of ice in the water, using her powers to shoot blasts at the base of the ship. The water around completely froze. The ice expanded outwards from the ship and deeper into the water.

As she continued to use her powers, Elsa kept hoping Leo would keep his promise, and that he and his brothers would keep her sister safe.

Back on the ship, Mikey pointed to Dregg, "The jig is up, Head Blade!"

"'Head-Blade'?" was all Dregg could reply out of confusion.

"DEMONS! DEMONS!" the Duke shouted as he pointed to the Turtles and cowered behind his guards.

Raph sighed, "You know, I'm just about sick of being called a demon!"

"I know!" Donnie agreed, "It's not an accurate description." 

Raph rolled his eyes at that, though that wasn't his point.

"What are you?" Hans asked.

"They're my friends," Anna told him once Kristoff finished untying her.

"And we're the ones who are going to bring you down," Leo added.

"Bring us down?" Hans said with a light laugh and a smile, "Look around you."

The six looked around at the two dozen killers armed with all sorts of crude weapons.

"One party here doesn't have the best of odds," Hans stated.

"I know," Raph agreed, "You should have brought A LOT more."

The devious fallen royal glared at the Turtles, "I don't know what you are. But this does not concern you four. Step away now, and you can live the rest of your lives in peace."

Leo glared back at Hans, "Go screw yourself, pretty boy."

The turtles all drew their weapons, and Kristoff drew two hatchets. They were ready to put the spoiled prince in his place, once and for all.

Chapter Text

As Elsa finished freezing the water around the ship, she made certain that it was thick and strong enough to keep the ship from moving. She saw one of the Night Blade's men go flying off the ship and land smack on the thick ice. She quickly used her powers to form ice around his unconscious body, to keep him from moving.

Elsa knew it had begun. All she could do now was hope Leo and his brothers were up to the task.

Leo blocked and parried swords coming from three men charging at him with his katana. He was backed to the edge of the ship. He blocked one sword and kicked the first one in the gut, then slammed the handle of his blade at the back of his head.

The second one came with another sword and lunged in an attempt to stab him. He formed an 'x' with his blades and caught the opposing blade. He snapped it out of the man's hands. Leo sliced the man in his legs, immobilizing him.

The third came charging in and screaming. The leader of the Turtles just moved and tripped him, and watch him fall onto the thick ice below. He saw ice form around the man and saw Elsa.

Elsa looked up at him, Leo smiled, telling her that they got this. before returning to the fight. That was what Elsa needed, and she gave a light smile of her own.

A spearman lunged at Raph, whom the Turtle easily blocked with his sai. He caught the blade with one of his sai, and with the other snapped the spear in half. The man looked in shock before a foot was delivered to the face.

A small explosion had knocked the aggressive Turtle back a few feet. He got up and saw it come from a man on one of the ship's rope ladders, who was lighting another bomb. Raph quickly threw two shurikens at him, nailing the man on the shoulder. The mercenary screamed in pain as he fell off the rope ladder and the ship.

A whip was wrapped around one of Raph's hands. He looked and saw that it came from one man a few feet away. Another whip caught his other hand. Both men tried to pull, in an attempt to rip his arms off. He simply smiled and pulled hard, crossing his arms. Both men were slammed into each other.

"This is the most fun I've had here," Raph told himself.

Donnie's staff continued to collide with swords and spears as at least four men came at him. He had been pushed back to the bow of the ship, near the edge. The four men all looked at him with sinister intentions.

He drew one of his smoke bombs and threw it on the ground, as the four charged in. The sounds of wood hitting people and painful grunts could be heard in the purple smoke until two were thrown off the edge. The smoke cleared it and revealed the smart Turtle standing triumphantly over the remaining two.

He saw more men heading his way, to which he twirled his staff and charged in as well.

Mikey flashed his nunchucks as five men surrounded him. He did it in an attempt to show off a piece of his bravery.

They all charged in. One brandished an axe, which he caught in his chain and flipped over into another oncoming killer.

One with a hammer came in, to which the fun-loving Turtle just slammed his nunchucks across his face, sending him flying.

Two charged in at the same time, but he just extended his chain and tossed it, wrapping around the main mast. He swung around it and slammed both his feet into his two attackers.

The last one attacked with a sword, to which he just back-flipped out of the way.

"Stand still, you freak!" the killer demanded.

"Hey man. You can't take the fire out of…" Mikey back-flipped again, "…Doctor Flippenstein!"

"What?" the fighter responded, which was all he could say. 

Mikey charged in and swung his nunchucks. The killer ducked, only for Mikey to do a cartwheel kick and knock him back a couple of feet.

The party-loving Turtle came up to his opponent as he fell unconscious, "You know what would have worked there? Back-flip!" 

Kristoff had two hatchets armed and ready. Two men slowly approached him, each with knives.

Anna was behind him, hiding behind the foremast. She looked at the upcoming battle with worry. Not for herself, but for him.

One finally charged at him. Kristoff ducked to avoid the slash, and slammed his elbow into the assassin's abdomen hard, incapacitating him.

The other tried to impale him from above as the ice harvester was still in a ducking position. He simply gave an upward slash with one of his hatchets.

He did not see another one running at him from behind. As the assassin was about to strike with his sword, he felt something hard hit him in the back of his head. He fell to the ground unconscious.

Kristoff turned around and saw the man on the ground, with Anna standing over him, with a broken guitar in her hands. It wasn't hard to figure out what happened.

"Where did you get that?" Kristoff asked.

"Found it. Let's go," Anna urged, wanting to get more involved, but Kristoff stopped her.

"Whoa, hold on," he warned, "I'm not sure that's a good idea."

"But we can help!" the queen's sister complained.

"You wanna get involved in the middle of that?" Kristoff asked, gesturing to the battle.

They both saw the Turtles duking it out with over two dozen killers, with them performing feats thought to be believed as impossible, and winning.

"Good point," Anna stated. She was smart enough to know she would just get in her friends' way.

A couple of workers at Arendelle's docks had just caught notice of what was happening in the harbor. They couldn't quite make it out though.

"What's going on out there?" one of them asked.

The other worker took out a spyglass and got a good view of what was happening. He saw the queen freezing water around a large black ship and men to the ice as they fell from the ship. He looked up at an even stranger sight: four giant turtles were fighting over two dozen men. He then noticed the princess was there as well.

He handed the spyglass over to his friend, hoping he wasn't going insane, "Tell me you're seeing that." 

"I'm seeing, the queen freeze a ship, with four giant turtles fighting all the men on the ship. Wait, is that the princess?" the second worker asked, "Get the guards! Get everyone! This they gotta see!"

Hans, the Duke, the duke's two guards, and Dregg could not believe what they were seeing.

What Dregg saw, were a bunch of monsters making his men look like pushovers. This made him quite angry. The Duke just saw four demons coming to the queen's aid, proving in his greedy mind that the queen was indeed a 'monster'. Hans didn't care what they were. They were getting in his way for revenge. He would not have his plans thwarted again.

Leo had just kicked another mercenary off the ship and onto the ice, only to be imprisoned in it like all the others down below. Leo looked at his blade and saw in the reflection an incoming sword. Leo blocked the blade with his katana and saw the wielder.

"So, Prince Hans of the Southern Isles, I presume," Leo stated.

"Not anymore," Hans confirmed, "Because of that stupid girl Anna and her witch of a sister, I was banished."

"You did that to yourself. I know who you are and what you tried to do to Elsa and Anna. You tricked Anna into getting engaged to you, left her to freeze to death, and tried to kill Elsa. And you told her she killed her sister and smiled at it all."

"Am I supposed to be hurt by that?" 

"You are by far, the biggest coward I have ever met, in my entire life. And I've met quite a few."

Hans growled, "No one insults me like that."

"Guess what? Karma's coming right back at you, and you can't weasel your way out of this one."

Hans has heard enough. He swung his sword, which Leo easily blocked.

Raph smiled as he looked at the unconscious men he had just taken down. An arrow was shot right passed his face, he turned and saw the Duke of Weselton, with his two guards, each with crossbows.

"That was just a warning shot, demon," the Duke warned, "We've had enough of that witch Elsa and her pets."

"First of all…" Raph began, "We're not demons. Second of all, I'm no one's pet. And third, just because someone's got powers doesn't make her a witch."

"Just like a demon to defend his mistress…" the Duke retorted but was interrupted.

"I said, I'm not a demon you moron!" Raph stated, "So why don't you get lost, oh mighty 'Duke of Weaseltown'?"

"'Weselton'!" the duke corrected sharply. 

The two guards aimed their crossbows at Raph

"Crossbows? Really?" Raph asked with a cocked eyebrow. He was hoping for an actual challenge.

Mikey and Donnie had just finished off three more assassins, and fist-bumped each other. They turned and saw Dregg, with two rather large swords.

"So Head Blade wants to play?" Mikey taunted.

"My name is Dregg!" Dregg shouted, "And who are you to challenge the might of the Night Blade?"

"'Might of the Night Blade'?" Donnie repeated, "Dude, we know a couple of  squirrels  who can fight harder than these chumps."

"And a dog and a fish," Mikey added.

"That does it!" the mercenary leader yelled as he charged in at the two turtles.

Kristoff punched one more assassin off the ship, "I think that's all of them."

"Looks like it," Anna agreed. 

They both looked at where the Turtles are now.

"Still think we should help?" Kristoff asked with a half-smile.

"Nah, I think we would just get in the way," Anna answered. All they could do was just sit back and watch the show.

Elsa was just now walking around the ship on her thick 'island' of ice, freezing any mercenary that she may have missed. She did a count, concluding that there were at least twenty of them there. She was a tad bit amazed at how the Turtles easily beat all those killers and were keeping Anna safe. She wasn't completely surprised though, not after hearing about some of the adventures the Turtles had.

When she froze the last of them, she looked out to Arendelle and saw what looked like the entire kingdom at the docks, looking out at the battle. She got a tad worried for a second, but a thought came to her. The Turtles have already done so much for her, and she had just found a way to repay them.

Leo continued to block Hans' strikes, his katana clashed with his broadsword. Though Hans was trying hard, Leo wasn't giving much effort. This guy wasn't much of a challenge.

"That all you got?" Leo taunted, "I could do this all day."

The devious man growled and slashed. Leo just knocked the sword out of Hans' hands and kicked him away.

Hans growled as he got up. He raised his fists, wanting to take the turtle in hand-to-hand combat.

Leo withdrew his blades, making a 'bring it on' gesture, accepting the challenge.

Hans charged in and volleyed punches at Leo. Leo simply blocked with his arm or swerved out of the way, but still no challenge.

"And here I thought this was gonna be a real fight," the leader of the Turtles taunted.

"You will not get in my WAY!" Hans shouted.

"Revenge huh? You sound just like someone I know." 

Leo continued to fight as Hans continued to try and punch him, "He let his need for vengeance cloud his judgment, which lead to him getting beaten quite a few times."

Hans still tried to hit him. 

"Funny thing about revenge? It gives you tunnel vision and lets you see what's only in front of you, nothing else. Pretty soon, if you let it consume you…" 

Leo jumped. Hans looked around frantically for him, but couldn't fight him. 

"…You lose sight of everything," Leo finished from behind, leaving Hans wide-eyed.

Hans turned around only to see Leo deliver an uppercut, knocking him off his feet and into the air. The prince landed on his front before he slumped into unconsciousness.

"One punch," Leo mused, "Still no challenge."

Raph continued to dodge the arrows the Duke's guards shot at him with their crossbows. It wasn't that hard, especially since the turtle had experience dodging laser blasts from Kraang droids.

The guards kept getting more and more frustrated, as they continued to miss until they finally ran out. They both looked at each other and nodded, discarding their crossbows and drawing their swords.

"Alright, finally some excitement!" Raph exclaimed, sai at the ready.

The two attacked. Raph blocked both their attacks with his sai. He kicked one in the face and sent him flying to the edge, then grabbed the other one and threw him at his partner. Both fell off the edge and onto the ice.

Raph turned to the Duke as the Duke was ponding and pulling at the door leading inside the ship.

As the Duke tried desperately to get the door open, a sai was thrown and stuck the door, shocking him. He turned and saw Raph grab him by his robes and throw him to the ground. When he tried to get up, Raph put his foot on his chest.

"I'd stay down if I were you," Raph warned, "And don't even think about calling me the d-word."

"Don't kill me! DON'T KILL ME!" the Duke screamed.

"Oh don't worry," Raph assured with a smug grin, "There's a nice cell with your name on it, Weaseltown."

"It's WESELTON! Weselton! Demon!"

"Oooh," Raph said as he shook his head, still a smile, "I warned you."

Elsa was just about to freeze the Duke's guards when she heard screaming and saw the Duke fall and hit the pile of his two guards.

She looked up and saw Raph, dusting his hands, with a smug grin. She smiled and shook her head.

Donnie and Mikey kept avoiding all of Dregg's attacks. He slashed madly with his large swords, but the two avoided them with ease. They flipped and dodge, not even bothering to attack, which ticked off Dregg,

"Stop your fancy jumping!" Dregg shouted, "Fight like men!"

"Do you see a  man  around?" Donnie asked as he drove a foot into Dregg's knee.

Dregg screamed in pain at his dislocated knee and saw Mikey deliver multiple nunchucks strikes all over his front.

After about ten or fifteen hits, he was down for the count.

"Head-Blade's looking a little dull," Mikey teased.

The Turtles all came to the ship, as the bad guys were defeated. They all high-fived each other and gave each other fist-bumps.

"'Night Blade'?" Raph began, "More like the "'Dork Blades'."

Anna came running up to them, "You guys were AMAZING! You were all… and they were all… and then…"

"Slow down Anna," Kristoff said as he put his hands on her shoulders, calming her down, "I think they know."

A pillar of ice rose to the ship, with Elsa on the top. She stepped onto the ship to greet her new friends.

"You four are something," she congratulated, right before Anna ran up to her with a hug, which Elsa was happy to return. The turtles, even Raph, couldn't help but smile at that. 

The warm and fuzzies were all interrupted by a grunt.

Hans struggled to get up. He flipped onto his back, opening his eyes to see Leo pointing his blade at him. Leo gave Hans a glare of contempt.

The other turtles gathered around as well, with Kristoff, Anna, and Elsa. Each with their glare as well.

Hans could only sigh in defeat and raise his hands, "I surrender."

Leo turned to Raph with a mischievous smile, "Wanna accept his surrender, Raph?"

Raph cracked his knuckles with his smile of mischief, "Not yet."

The next thing Hans knew, he was thrown into a sewage pit in the middle of Arendelle. He looked up, covered in raw sewage, to see Raph dusting his hands, surrounded by Leo, Elsa, Donnie, Kristoff, and Anna. 

"Now we accept your surrender," Raph told him.

"Gain way, bros!" Mikey shouted as he ran and threw an object into the sewage pit and slammed the lid.

"What did you throw in there?" Anna asked.

"Hornet's nest," Mikey answered plainly. 

They all looked a bit wide-eyed. They then heard angry buzzing and Hans screaming in pain down below. Mikey and Raph then fist-bumped.

Donnie's smile faded as he looked behind them all, "Um… guys?"

Everybody looked, and they saw what appeared to be all of Arendelle's populace.

The turtles saw the many eyes of men, women, and children all staring at them. No cover, no disguises. Just four mutant turtles.

"Well, let the screaming commence," Raph began with a sigh, fearing the worst. 

To their surprise, no screaming came.

A little girl walked out from the crowd, hiding something behind her back. She slowly approached Leo. When the girl came right up to the blue-clad Turtle, he had a few beads of sweat drip from his head.

The girl smiled and, to his surprise, handed him a small white flower.

Leo and his brothers all looked wide-eyed at this. Elsa walked up to the girl, took the flower, and handed it to Leo.

The girl's mother walked up to the group, "That's my daughter's way of saying 'thank you'."

"You don't think we're weird and scary?" Leo asked.

"Of course not," the mother replied, "You saved our queen's life. Who are we to complain?"

Elsa stepped up, gesturing to the Ninja Turtles behind her, "Everyone! Today, we will honor Arendelle's new heroes! Leonardo, Donatello, Michelangelo, and Raphael; the Ninja Turtles!"

To this, everyone cheered. Amid the cheering kingdom, Anna and Kristoff smiled looking at the heroes of the day.

The Turtles' look of shock soon turned to smiles of joy and relief.

"I could get used to this," Raph said.

"This is incredible," Donnie stated.

"Yeah, bros!" Mikey agreed, "We're heroes!"

Leo smiled and looked at the queen, "Elsa…" 

Elsa turned her attention to him and his brothers, "Thanks."

"Hey," she began, "What are friends for?"

New York

It was nighttime. Within the Big Apple was an abandoned cathedral. Only it served as the home and lair of the Foot Clan, the Turtles' worst enemy.

Underneath the roof of the cathedral was a throne, and the one who sat on the throne was the dreaded leader of the Foot Clan, a master of Ninjitsu, and Japan's deadliest killer: Oroku Saki, the Shredder.

On the Shredder's right stood the mutant assassin, Tiger Claw, the Shredder's second-in-command, and his greatest student.

Down below the throne, below the flight of stairs, standing at the wall, arms crossed was the martial artist, the one formally known as Chris Bradford. But now he was the mutant dog, named Rahzar, a moniker given by Mikey.

Pacing across the room was Rahzar's partner, Xever, formerly a street thug and leader of the Purple Dragons. Now he was a mutant, cybernetic fish, which Mikey has called Fishface.

The four were waiting for a report from their partner, having been waiting for quite some time. Finally, a Kraang-droid head appeared from the left of Shredder's throne, displaying the hologram of another Kraang droid.

" Greetings, one called, Shredder,"  the droid greeted.

"Your report is late," the Shredder observed, "What is the status of your portal?"

" That which is known as the portal that will lead to the dimension of Kraang, cannot be completed,"  the Kraang began, " The ones known as the Turtles intervened."

The Shredder slammed his fist on the throne's arm when he heard that, "What happened?"

The Kraang droid told Shredder how the Turtles got into the Kraang base, stole the dimensional inducer, and vanished with it.

"You are incapable of traveling between dimensions?" Tiger Claw asked.

" Negative,"  Kraang corrected, " Kraang can travel between dimensions, in that which is known as small squads, but those which are known as armies cannot be transported."

"Do you have any  good  news?" Fishface asked.

"That which is good news is…"  Kraang began, " Kraang has determined the dimension, the ones known as the turtles, traveled to. Kraang is preparing that which is known as a squad to retrieve that which is known as the dimensional inducer."

"I will send two of my agents to assist you," the Shredder told the alien, "Wait for them."

The Kraang droid nodded and the hologram cut off.

"Bradford, Xever," the Foot Clan's leader summoned.

"Yes, Master Shredder?" Rahzar asked.

"You will go to this dimension with the Kraang," Shredder instructed, "Your primary objective is locating the Turtles. You will find them, bring their broken bodies to me, and wipe out anyone who stands in your way."

"Don't worry, Master Shredder," Rahzar reassured, "The Turtles will be as good as dead."

"And if anyone does get in our way…" Fishface added, "We'll peel the skin off of them and drop them at your feet."

The two evil mutants left the Shredder's lair, ready to do what they do best: fight and kill.

Chapter Text

New York sewers

Within the lair of the Turtles, was the former human Hamato Yoshi, now the rat master known as Master Splinter, mentor, and father of Leo, Donnie, Raph, and Mikey. 

He sat in the lair's dojo, meditating, with his breath smooth and slow, completely at ease and in perfect harmony with the universe and nature. However, this peace was interrupted when he sensed the tension in the air.

Splinter opened his eyes slowly, and his ears picked up footsteps pacing coming from outside the dojo.

Outside the dojo, someone was pacing in the lair's living area. It was the teenage kunoichi Karai, or Miwa. 

She had been the adoptive daughter of Shredder most of her life, but after realizing Splinter was her true father, and the monster Shredder is, she left the Foot and joined Splinter. The Foot Clan's leader did not take that lightly. When she tried to get revenge on him, she was accidentally mutated into a snake-like creature. Recently, however, she was able to get her mutation under control, able to transform from her snake form to her human form at will, provided she didn't get too angry.

"Miwa?" 

Karai heard, stopping her pacing. She turned to her father. 

"What troubles you, my daughter?"

"'What troubles me'?" Karai asked, rather loudly, "The Turtles have been gone for too long. That's what troubles me."

"One must learn to be patient," Splinter told his daughter.

"Oh, I've been patient alright. I've been patient for THREE DAYS! I know I just got here, but normally a recon mission doesn't last that very long."

"I sense tension and worry in your tone," Splinter observed.

"Well of course I'm worried. My brothers have been gone for three days! I've tried to call them on their T-phones, but no answer."

"They are fully capable of taking care of themselves."

"I know they can. But shouldn't you be worried too? They're your sons."

Splinter sighed a bit, and looked away for a moment, "I do worry, I fear for their safety every time they leave the lair."

Karai calmed down a bit before continuing, "It's been three days though, something isn't right." 

The former Foot Clan subordinate then began walking towards the exit, into the abandoned subway tunnel.

"Karai? Where are you going?"

"I'm going to look for them."

"But you know that Shredder is looking for you."

"Some of us can't just sit here and do nothing," Karai argued before leaving the lair.

Splinter felt a sense of shame come over him. Those were the exact words April O'Neil told him during the Technodrome-crisis with the Kraang. His look of guilt quickly turned to that of determination.

Karai was walking down the tunnel but stopped when she heard her father call out.

"Wait!" 

She turned around and saw Splinter come up toward her.

"Don't try and stop me, father," Karai told him.

"I'm going with you," Splinter said.

"What?" 

"You are correct. Something is not right here. If my sons are in danger, and my daughter is risking herself to find them, I will not stand by and let my children be put in harm's way."

Karai smiled at that. All she could do was embrace Splinter in a hug. Splinter was a tad surprised, before returning the hug. Karai rarely showed off her soft side.

They broke out of it, and Splinter was the first to speak, "Let us find my sons and your brothers."

New York City, nighttime, 5 hours later

Karai and Splinter both split up to cover more ground. During their search, they kept to the rooftops and off the streets.

Splinter advised Karai to remain conspicuous during the search.

He leaped from rooftop to rooftop, occasionally looking down quickly into an alleyway, or down into the streets. His acute senses allowed him to capture all the details very quickly. When he was certain the area he was searching for didn't have anything that could be useful, he left. 

After five hours, he decided to head to the rendezvous point where Karai would be waiting.

Karai was on the roof of a movie theater, talking into her T-phone. 

"You're sure you haven't seen them?" 

The caller's answer couldn't be heard, and only Karai heard it.

"We've been searching for five hours and haven't turned up anything." 

She paused as the caller told her something. 

"I'm sure they're alright but still…" 

The caller interrupted Karai briefly, she couldn't help but sigh.

"Alright. I'll let you know if we find anything. Okay, thanks anyway. Bye." 

Karai hung up, a disappointed look on her face.

Splinter had just landed on the roof. 

"April hasn't seen them either," Karai told Splinter.

"Have you tried Casey?" Splinter asked.

"Yes, I have. Dead end there too. Anything on your end?"

"I'm afraid not."

Karai looked off in a random direction, but something got her attention. 

"Father," she tried to get his attention while pointing in a particular direction.

Splinter looked where she was pointing and saw what, or who got her attention: Rahzar and Fishface. They were across the street, running and leaping from roof-top to roof-top, neither noticing him nor Karai.

"What do you think  they're  after?" Karai asked.

"I cannot say for certain," Splinter answered.

Karai thought of something that made her eyes wide, "Wait. What if they know something about the Turtles?"

"Perhaps," Splinter stroked his thin beard, "But they may not."

"What if they do, though? Maybe Shredder…"

"You may be right. Follow close, but do not let them spot us."

Karai nodded, and the two pursued the two mutants.

Rahzar and Fishface have been jumping and running for about half-an-hour, and thankfully, hadn't noticed their pursuers.

The two stopped when they reached their destination: the roof of a seemingly abandoned warehouse.

Splinter and Karai stopped at the roof across the warehouse and watched their quarry enter in through a ceiling window. Before Splinter could follow, Karai took out two white balls and handed one to the master.

"What is this?" he asked.

"A special kind of powder," Karai answered, "Put it on, and it'll mask our scent from Bradford."

"Good thinking," Splinter commended, before opening the ball and spreading the powder around his body, on his neck, his arms, and a little coating on his robe; Karai followed suit as well.

When they were certain they were scent-invisible, they jumped to the warehouse rooftop and entered through the ceiling window.

When they two got in, they stuck to the ceiling beams to avoid being spotted. They looked down and were both surprised at what they saw. 

There were at least five dozen Kraang droids, and even a Kraang ship just hovering off the floor. There were a few Kraang at what seemed like their council, but all the rest had their signature laser rifles, appearing as if they were preparing for a full-scale assault. Rahzar and Fishface were talking with the apparent Kraang in charge.

"Is your squad ready?" Rahzar asked.

"That which is known as, the search and destroy squad that is meant for the purpose of both searching and destroying is in the status that is known as ready," the Kraang answered.

"We'll take that as a 'yes'," Fishface stated, "So, what is the plan, again?"

"That which is known as the plan is, to find to travel to the dimension that Kraang wishes to travel to," the Kraang relayed, "Kraang will search for that which is known as the dimensional inducer, as well as to locate the ones called the Turtles."

Splinter and Karai looked at each other with that statement.

"Okay, we have an idea where they are now," Karai summed up, "So do we attack?"

"No," Splinter answered, "Neither of us knows how to use the Kraang's technology. If we attack, we risk stranding my sons wherever they are."

"So what  do  we do?" Karai asked impatiently.

"We'll follow them through their portal. Once we're through we'll find the Turtles, and we'll fend off this assault together."

"Got it."

With that, the two quickly and quietly jumped from the ceiling beams. They silently made their way to a stack of boxes at the end of the warehouse. They hid behind and were completely unnoticed by the Kaang and Shredder's mutants.

"That which is known as the coordinates are found," one of the Kraang at the council reported.

"Activating that which is known as the portal," another Kraang answered.

With that, a large pink, glowing, triangular-shaped portal opened and expanded till it almost reached the ceiling then stopped.

"What are we waiting for then?" Fishface asked, "Let's go crack some shells."

Fishface and Rahzar were the first to enter the portal, followed by the many armed Kraang droids. The Kraang ship entered the portal as well.

Right before it did though, Karai and Splinter quickly ran from they're hiding place and entered the portal right before it closed.

Large Cave, North Mountains near Arendelle.

Within a large, empty, cold cave that's as tall as a three-story building, a huge, pink triangular portal opened. As soon as it did, the mutant dog and fish emerged. Soon, the five dozen Kraang droid soldiers emerged as well, followed by the hovering Kraang scout ship. 

When the ship left, Karai and Splinter came out from the portal right before it closed. Still unnoticed, the two each hid behind a large stalagmite.

Rahzar and Fishface soon left the cave to look at the sight in front of them; it seemed like daytime, but there was snow and snow-covered evergreens everywhere.

They looked around, and something caught Xever's attention. 

"Down there!" Fishface pointed down the slope. 

Rahzar looked and they could see a large settlement near the sea. Even though they were far enough away, they could tell it was a lively and populated place.

"A hundred bucks says the Turtles are down there," Rahzar said.

A Kraang droid walked between them, with a small scanner in its hands.

"That which is known as the inducer that is the dimensional inducer is in that human settlement," the droid relayed.

"Are all of you going down there?" Rahzar asked.

"Negative," the Kraang answered, "A few Kraang will remain behind in that which is known as the cave that is the cave that Kraang emerged from. Kraang must make a temporary base, a base in which Kraang can call more Kraang for backup and Kraang can travel in and out of this dimension."

"Alright," Rahzar said, "My partner and I will stay here and guard." 

This earned a surprised look from Fishface.

"Understood," the Kraang relayed.

Fishface pulled Rahzar close and whispered, "Exactly what are you doing?"

"We don't know if the Turtles are down there, and I don't want to give away ourselves just yet," Rahzar answered, "Besides if they  are down there, the Kraang will soften them up. Then we finish the job."

Fishface couldn't help but smile at his partner's plan, "Bradford, there are times that I like you."

From behind an evergreen, just outside the cave, Karai and Splinter had just made it out of the cave without making even a peep. They had just caught Rahzar's plan. All Karai could do was glare.

"Those cowards," she gritted, her pupils almost turned into slits, right before Splinter put his hand on her shoulder.

"Calm yourself, my child," Splinter told her in a smooth, relaxing tone.

Karai breathed deeply and calmed down, her eyes turned back to normal.

"I'm sorry," she apologized, "It's just…"

"I know. But we cannot afford to give ourselves away. We are here now; let's find the rest of our family."

"Alright. Let's go." 

The two then made their way down the mountain, staying out of sight of the small Kraang army heading in the same direction.

Chapter Text

Arendelle, Castle Courtyard

It was a bright and sunny afternoon for all of Arendelle. Within the courtyard, Donnie and Kristoff are dueling with staves. While Kristoff was indeed trying, Donnie wasn't.

Kristoff would strike and sweep with his staff, while Donnie simply blocked it with little effort. When he charged in, Donnie merely tripped him.

The ice harvester got up, groaning to see the purple-clad turtle offering a helping hand, which he gratefully received.

"You're getting better," Donnie congratulated.

"Not nearly as good as you, though," Kristoff admitted, "I mean, you beat up dozens of assassins with only a stick! I got just three or four."

"Hey, don't worry about it. My brothers and I have been training since before we could walk. You hadn't had any combat training, and ninjitsu isn't something you pick up overnight."

"I know. But still, anything's better than nothing."

"Couldn't have put it better myself."

Kristoff smiled at his friend's advice.

"Hey guys, what are you up to?" they heard Anna shout. 

They both turned to see her leaving the castle's inner gate to the courtyard, with Olaf riding Sven next to her.

"Donnie's showing me a few basic ninjitsu moves" Kristoff explained.

"Ooh, cool!" Olaf agreed, "Could I learn some of that?"

"Well uh…" Donnie had second thoughts about training the snowman ninjitsu, due to it being impossible, but he noticed something. "Hey, where's Mikey? Isn't he supposed to be with you?"

"He told me to come out here, said he wanted to show me something," Anna explained, "Didn't say what."

"Knowing Mikey, it's probably going to be something crazy," Donnie said.

"AND HERE WE ARE, FOLKS!" they heard a voice shout. 

They all turned to the top of the castle, where they saw Mikey at the highest point, the tip of the tower, holding a skateboard and balancing at the top. 

"AND NOW THE KID GOES FOR THE WORLD RECORD!" Mikey shouted as if he were a sports announcer, "HE WILL ATTEMPT TO JUMP A CASTLE COURTYARD!"

They easily picked up on his hint. 

"He's not serious," Kristoff stated.

"BOOYAKASHA!" Mikey shouted as he jumped on his board and started riding down the roof.

"He's serious," Donnie replied.

As Mikey rode straight down the large diagonal roof, closer to the edge, which was curved up like a ram's horn, Donnie had a typical unsurprised look on his face, unlike Kristoff who had. The latter was thinking Mikey was either brave or stupid. Sven had the same look as well. Anna had a look of extreme worry, not wanting her new best friend to get hurt. Olaf just gazed in amazement.

Mikey finally reached the edge, which he flew straight off. Once he was in the air, he took out his nunchucks and with them formed the shapes of specific letters; first was a T, next was an M, the third was an N, and the last was another T. He finally made it to the smaller outer gate, which he ground against the edge of and around the outer wall, then jumped off when he was about to slam against the wall and landed safely in the courtyard. But not before he slammed his foot on his board, and caught it.

"And he sticks it!" Mikey shouted.

"That was amazing!" Anna excitedly shouted as she ran towards Mikey, "How did you do that?!"

"Years of practice sister, years of practice," Mikey answered.

"Have you always done stuff like that?" Kristoff asked.

"Yeah dude, my bros and I always board back in New York," Mikey replied.

"Where'd you even get that skateboard?" Donnie queried.

"It was in the Shellraiser," Mikey answered, "Hey, any of you guys seen Raph?"

"Oh, I know! I know!" Olaf answered like a school student, with his stick arm raised, "I think he said, 'I'm not sticking around here, I've got stuff to do'."

"I do not sound like that." 

They all turned to Raph who climbed over the wall and into the courtyard.

"Where have you been?" Donnie asked.

"I was trying to get some morning jogs, which I couldn't thanks to everyone in the town swarming me," Raph explained.

"Dude, those are our fans," Mikey said, "It could be worse."

"Whatever," Raph replied.

Ever since the Turtles saved Elsa and Anna from Hans and the Nightblade, the ice queen introduced them as their kingdom's newest heroes. 

Everybody in town loved them, especially the children. They could walk out in broad daylight and no one would start a panic, not like in New York. Though they would be forced back to the castle due to their fans swarming them and asking questions: Where did they come from? Have they always been turtles? Are there others like you? Why do you wear headbands and carry weapons? The only thing that kept them from swarming the castle where the guards.

"Shouldn't you be happy?" Anna asked, "Everybody in Arendelle loves you guys."

"I'm glad, don't get me wrong, but it's not like we can live here 24/7," Raph said.

"Right," Anna remembered, "I'm sure Splinter and your sister are missing you guys."

"'Sister'?" Kristoff and Olaf asked at the same time.

"Mikey hear told me you guys had a sister," Anna explained, causing both Donnie and Raph to give a partial glare at their youngest brother. Mikey smiled innocently at that.

"Ooh, you four have a sister?" Olaf asked excitedly, "What's she like? I bet she's the nicest, gentlest, warmest person ever."

The Turtles each exchanged glances, knowing how wrong Olaf was.

"Yeeaaaa… no. Not really," Raph stated.

"What do you mean?" Anna asked, "What is she like?"

"Well, she's not really 'nice' to say. She's more sarcastic, rude, and rebellious," Donnie said.

"As for 'gentle', she's quite deadly, especially if she gets pissed off," Raph added.

"She takes a while to warm up to," Mikey said.

"How come you guys never said anything about her?" Kristoff queried.

"Um… well…" Donnie tried to remember.

"Hey, where's Elsa?" Mikey asked, not wanting to get to in deep with this scenario because they would have to bring up a certain someone who wants each of their heads on his wall.

"I think I saw her and Leo somewhere upstairs," Olaf said.

"What do you think they're doing up there?" the ice queen's sister asked.

Elsa's room

From the queen's room were both her and Leonardo. Both were sitting on the floor, each with their eyes closed and in a meditative position. 

Leo thought it would be a good idea to teach Elsa how to meditate, to better control her powers. Granted, she has better control than she did when she was younger, but she still had trouble. And not wanting to risk repeating events at her coronation party, she gratefully accepted Leo's offer, though it proved to be harder than she originally thought.

Leo sat on his knees and legs, his hands on his upper legs. His eyes were closed, and his breathing was slow and steady. He seemed completely at peace.

Elsa was in the same position, right next to Leo. Though at first, she looked content. A few seconds later, she began to lose focus. She opened her eyes and broke out of the trance. She looked at Leo still in his trance.

She tried again. Closing her eyes and inhaling deeply. Elsa seemed to get back into it but soon slipped out of it again. She grunted as she did.

"You okay?" she heard someone ask, already too deep in the immersion. 

She turned to Leo who was looking at her with concern.

"I'm fine," Elsa answered, "It's just… I can't seem to focus."

"Yeah, I noticed," the Turtles' leader observed, "What's wrong?"

"You know how I said I can control my powers better now right?" she asked, to which he nodded, "Well… I still can but… I can't help but think what if I…"

"Do something bad Maybe freezing the kingdom again? Or even Anna?"

Elsa nodded, "I just, can't help but worry."

"You can't let fear control you. You have to learn to face it, or it'll stick with you for the rest of your life. Believe me, I know."

"That's the thing, Leo. I don't think I know how."

"I think I do," Leo said, gaining the queen's curiosity, "Try it again, except this time, focus on something else."

"What?"

"Anything. It could be a person, an object, or a moment in your life. Something that makes you feel happy and content."

Elsa thought for a moment, trying to think of something while giving a smile, "I think I have something."

"Then give it a whirl," Leo encouraged.

Elsa resumed her meditation, this time with Leo observing. She inhaled deeply, and a smile slowly formed. She slowly got up on her feet, eyes still closed. She walked a few feet, earning a curious gaze from Leo. She stopped, her eyes still closed and still smiling. She slowly opened her hands, with white and blue sparkles forming. Elsa cast energy onto the floor, which slowly rose until it reached five feet in height. She stopped, and what stood was an ice sculpture of Leonardo.

Leo looked in surprise at what Elsa just made. It looked exactly like him, it captured every detail, from the mask to the straps, to the sheathed swords on his back, the shell, the eyes, and even a smiling face.

"Well, what do you think? Not too shabby?" Elsa asked with a smile.

"Elsa…" Leo exhaled, trying to find the right words while grinning at her work, "I… this is…amazing. Don't know why you thought this was a curse."

"Well, it's my way of saying 'thank you'."

"What were you thinking of?"

"It was me and Anna. We were little. We were outside in the snow, playing, making a snowman, snowball fights, and sledding. Just that moment. It's years ago, but… it's the best I got."

"Well, if it makes you happy, then just focus on that moment. And I thought your 'thank you' was the whole 'Heroes of Arendelle' thing. You didn't have to do that, you know."

"Are you kidding?! That was the  least  I could do. You and your brothers have done so much to help me. Not just saving me and my kingdom, but just being there. You four have had no problems with my powers, and Anna just loves you guys. Why just yesterday she said Michelangelo was like a younger brother to her. All of you are like brothers to her."

"We'll do what we can."

"I'm serious, and here you are, helping me with my powers. I kinda agree with her," Elsa explained. She had come to view the turtles as brothers to her, even thinking of Leo as an older brother, despite that he was technically younger.

"You four have done so much. There are no words to express how grateful I am."

"Just a thank you is good enough," Leo gave another smile.

"Hey, um, Anna did mention something of you four having a sister. What's that about?"

Leo's smile dropped at that, "Well… it's a little complicated." 

Leo didn't want to share this information, primarily because he would have to bring up a certain enemy of his, and he didn't want to terrify Elsa.

"How's that?" Elsa asked.

"You see, uh…"

It was until something rocked the entire castle, knocking both of them off their feet.

"What was that?!" Elsa panicked.

"Whatever it is, it can't be good," Leo assumed.

Castle courtyard

A large explosion erupted from the ground by the main gate, catching the attention of the three turtles, two humans, the snowman, and the reindeer.

From the smoking crater came out three figures, completely unfamiliar to the humans, but all too familiar to the turtles: Kraang droids.

"What the heck?!" Kristoff stated.

"Who are these guys?!" Anna questioned.

"Oooh, crud," Raph said.

"Kraang, the ones known as the turtles have been located by Kraang," one of the droids observed.

"Those known as the turtles have made allies with the humans of the dimension of which Kraang has traveled to," the second droid stated.

"Destroy first, capture for interrogation later," the third droid repeated before they began blasting.

The turtles ducked and jumped out of blaster fire. Raph helped Kristoff and Anna get to cover behind the fountain, with Sven and Olaf following.

"You stay here," Raph instructed as he drew his sai and jumped to the battle.

Castle halls

Leo and Elsa ran through the halls to get to the courtyard to get to their friends and respective siblings. When they turned a corner, they came to two Kraang droids, each with a primed blaster.

"It is the one known as Leonardo," one of the droids said before they began blasting.

Leo tackled Elsa behind the corner, and out of the line of fire.

"What are those things?!" the ice queen questioned.

"Bad guys.  Major  bad guys," the blue-clad Turtle explained, "Just stay here, I got this." 

He drew both his blades and charged in.

Both droids tried to shoot the turtle down, but he was quick to avoid all of them. He rolled and kicked one off to the side, then moved to slice the second one in half. Once that droid was dealt with, the one he had previously kicked got back up and was about to shoot him until a force slammed it against the wall.

Leo turned to see the Kraang droid stuck to the wall, with its arms and legs bound to it by ice. He then turned to Elsa who had just lowered her arms. 

"I take it you know what these things are?" she asked.

Before Leo could answer, the Kraang itself launched from the droid and leaped onto Elsa's chest. She fell to the floor as it crawled to her face and snarled at her. She screamed as she threw it away. The Kraang then began to quickly crawl back towards Elsa, as she stammered backward wanting to get as far from the hideous creature as possible. But it came at an alarming rate, though before it got too close, Leo blocked its path with his katana. He kicked it away, and when it landed it squealed as it stammered away.

Leo looked back to the terrified queen, who was breathing like she was about to have a heart attack.

"You alright?" Leo asked, offering Elsa a hand, which she took.

"What… was… that?" she stammered.

"I'll explain later, right now we have to find our friends."

Castle courtyard

Anna, Kristoff, and Sven hid behind the fountain as the fight outside continued. Olaf was easily distracted by the purple bolts that flew by.

"Ooh, pretty," the snowman lulled.

Raph was able to leap over the blasts one of the Kraang droids shot at him. He jammed his sai right into its neck and severed its head.

Donnie twirled his staff to deflect the shoots from the droid he was up against. He deflected one of the bolts back to the gun, knocking it out of the robotic hands. He then batted the droid away.

Mikey rolled around the ground, avoiding any of the blasts, then used his nunchuck chain to wrap around the droid and toss it into the fountain.

The two humans and deer looked as the droid short-circuited from the water. They both saw pink tentacles emerge from the machine's chest as the Kraang emerged and snarled at them. Anna screamed and instinctively clung to Kristoff, who too screamed, with the reindeer going wide-eyed.

The Kraang was then bashed in the head by Mikey's nunchuck, right before Mikey grabbed the creature and threw it down the hole it came out of.

Once the fight was over, the Turtles regrouped. The three came together to discuss what happened, but before anyone could say anything, Leo and Elsa ran out into the courtyard.

"Anna!" Elsa shouted. 

Anna ran to her elder sister and they both embraced. Leo came to his brothers.

"You guys had some too?" Leo asked.

"Yeah," Raph answered, "How did they even find us?"

"Wait, hold on," Kristoff interrupted, "You knew what those things were?"

"Unfortunately," Donnie said.

"Those creatures are called the Kraang," Leo said.

"'The Kraang'?" Elsa asked.

"What's a Kraang?" Anna asked as well.

"There these creatures from another world called Dimension X," Donnie exposited, "They're a hostile race who have been trying to turn our home into a place they can live on."

"Yeah," Mikey said, "These guys are the same ones who invented the mutagen."

This revelation made the humans and reindeer have wide eyes.

"Those things turned you into, well, you?!" Anna questioned.

"Accidentally, but yeah," Leo answered.

"I bet they could use a hug," Olaf said out of nowhere.

"No!" Mikey exclaimed, "These guys are  not  huggers."

"Mikey's right," Leo added, "You're more likely to get killed by them."

"Well, at least they're gone. Right?" Mikey mused.

"No, when it comes to Kraang, there's never just a few," Donnie said.

"You're saying there's  more  of those things?!" Elsa asked.

The next thing they heard was the sound of screaming and explosions coming from the kingdom, getting all their attention.

"Does that answer your question?" Raph said.

Chapter Text

Arendelle

The kingdom was in a complete state of panic. People ran everywhere, closing up, boarding down their homes, and barricading the doors from the inside. Children cry in the streets, looking for their parents. They were panicking due to the army of Kraang droids laying siege to the kingdom.

"Observe Kraang," one of the droids instructed, "Find that which is known as the dimensional inducer that is the property of Kraang. The ones known as the turtles are what are known as heroes in this settlement that is the settlement of humans. The humans in this settlement are friends of the enemies of Kraang and are therefore enemies of Kraang themselves. Resolution: Destroy all Non-Kraang."

The Kraang opened fire, blasting everything in sight. Their scout ship attacked as well. It emitted a purple lightning bolt from its front, destroying all the buildings it made contact with.

Arendelle's royal guards tried to fight back but were unprepared for such an unordinary enemy, they were mostly there to keep the citizens out of the chaos. If they tried to fight, they would lose. Their meager weapons were useless against a simple Kraang blaster.

The situation had appeared hopeless for the whole kingdom. That is until the Shellraiser came roaring down the streets, running down all the Kraang in sight. The vehicle came to a stop in the town square near a squad, with Michelangelo at the rear gunner's seat.

"Hey, brain-squids!" he shouted, getting the attention of the squad, "Eat hot man-hole cover!"

He opened fire with all their weapons. The gunner shot man-hole covers which decapitated and/or blasted all the droids in half.

Once the squad was dealt with, the door opened. The other turtles, the royal sisters, Kristoff, and Sven stepped out.

"Here's the plan," Leo instructed, "Elsa, Anna, and Kristoff, help get the people off the street and out of the line of fire. Raph and Donnie, help the guards out and tell them how to take out a Kraang droid. Mikey hit every bad guy you see. I'll take care of the Kraang ship."

Leo drew his swords and leaped into battle. Donnie and Raph drew their weapons and went off in a different direction, Mikey went in the opposite, leaving the sisters, ice harvester, and reindeer by themselves.

"Come on!" Anna exclaimed about to run after Mikey, only to be stopped by Elsa.

"Anna, no. Leo told us what to do. We have to get everybody out of here!" Elsa reminded.

"But I want to help!"

"Anna, we are helping," Kristoff argued, with Sven nodding, "These people are more important. Besides we wouldn't last long in this."

"But…"

"For once in your life, listen, " Elsa urged, "We don't know anything about these "Kraang" creatures. You could get killed, and I don't want to lose you again, please."

Anna just had a wave of guilt sweep over her, along with a tad of irony, for now, she was given the guilt card. Often it was the other way around. Anna was a force to coincide. She didn't know anything about the Kraang and the people were more important.

"Okay. Let's go."

Meanwhile, in the streets, there was someone completely oblivious to all the chaos around him: Olaf. He just walked through the streets as if it were another normal day, with a smile on his face no less. He welcomed all the Kraang he came across.

"Hi, Kraang number 23," he waved to one droid running past him.

"Hi, Kraang number 24," he waved to a droid shooting in a different direction.

"Hi, Kraang number… Oh sorry, Kraang number 16. I thought you were someone else."

The Kraang chose not to vaporize him because he possessed no danger. But he was quite high on the annoyance factor. A random alien shot had blasted a small hole into his chest.

"Oh look," Olaf noticed, keeping his smile, "I've been shot."

Castle Dungeons

"THIS IS AN OUTRAGE!" the Duke shouted from behind his cell, "I am the Duke of Wesleton! I do not belong here!"

"Give it a rest," Dregg said from the cell next to him, "The country impeached you when they heard you hired us. No one is gonna let you out."

"Has the 'Mighty Dregg' given up?" the Duke asked, "You are the Night Blade's leader, and you've given up!?"

"My whole organization is destroyed. I really should not have taken that job from you two," Dregg reminded.

Hans sat in the cell across from them, allowing the Duke's bickering to pass over him. Ever since the Turtles stopped the assassination attempt, Hans, the Duke, and the whole Nightblade have been arrested. The assassins were all imprisoned in the common dungeon above them; while the three were given the 'special suite' of the lower dungeon; each with their private cell. Though calling it a suite would be too nice a word. It was cold, dark, and damp, with only a wash bucket and a bed there.

The fallen prince looked calm, but inside, he was furious. He couldn't believe he got beaten again. It should have worked this time. If those Turtles hadn't intervened…. what were they? Why would they come to Elsa's and Anna's aid? He would try to find a way out of here, and some way to get revenge on his new reptilian enemies, he swore to it.

But his thoughts were interrupted by the sounds of explosions and chaos coming from outside. There was a window outside the cells. Hans and Dregg's were right at the wall, which if broken, lead to the outside of the castle.

"What is going on out there?" Hans wondered.

"Elsa and her demons are attacking," the Duke assumed, "I should have known it would happen sooner or later."

Dregg and Hans both rolled their eyes at this.

"Would. You. Please. Just. SHUT UP!" the mercenary leader shouted at the top of his lungs.

Right as he shouted, an explosion erupted from the wall. Hans was knocked off his feet and on his side. He slowly got up and coughed. When the dust cleared, he could see that the wall outside the cell was blasted off, leading right outside. Dregg and the Duke were unconscious from the explosion. The former prince grabbed the bars of his cell, and to his surprise, fell apart in his hands. He stepped out into the dungeon hall and saw the hole leading outside. An evil smile formed, knowing when to seize the moment.

Leo leaped from rooftop to rooftop, taking down all the Kraang on each roof hoping to get closer to the Kraang scoutship. He did take one down before, but only because he had a bazooka. Now all he had were his swords, getting up there was going to be tuff.

He then got an idea. He took out a shuriken and threw it at the ship's front, getting its attention.

"Hey, Kraang!" Leo shouted, "The one who is called your mother is what is known as a slob!"

At that moment the ship shot its energy bolt toward Leo, which he was able to avoid.

Step 1: Check! The ship is now pursuing him.

Mikey was bashing away all the Kraang droids he came across, yelling the same kind of shouts you would hear in an old ninja movie. They continued to blast lasers at him, which he was able to avoid due to his ninja agility. As he continued to bash them away, he failed to notice a droid coming at him from behind, thus allowing it to jam him with a shock stick.

The orange-clad Turtle was electrocuted and groaned in pain. Three more droids came in and followed. They pinned him and continued to mercilessly shock him. He saw no end to it until a mysterious force sliced all the droids in half.

Mikey sighed in relief and guessed who saved him as he heard a sword cut through the droids.

"Thanks, Leo. Don't know what I'd do without…"

He looked up and saw someone else which made him go wide-eyed.

"Guess again."

"Karai!?" Mikey exclaimed, "How in the… where… when…"

"Where are the others?"

"Oh uh, Leo's trying to take down the ship, Raph and Donnie are handling the ground troops, but how did you get here?"

"I'll explain everything after we take these things down."

"Sounds good to me," Mikey replied, readying his nunchucks.

"And when we're done here, you, our brothers, and I are going to have a little chat," Karai warned, drawing her blade.

"Oh boy," Mikey sighed, not looking forward to the inevitable scalding.

Elsa was escorting everybody down into the tunnels. The kingdom had a network of underground tunnels in the event of an emergency so that everyone could be safe. People were shoving and pushing their way down, while Elsa kept waving them through. They were currently at the tunnel that was a few feet from the docks.

"Keep going! Everybody, keep going! Don't get separated, stay together!" Elsa instructed.

When the last of the people in that area were in the tunnels, Kristoff and Anna, riding on Sven, came to Elsa.

"Anyone else here?" the queen asked.

"Not in this part," Kristoff said, "This is crazy!"

"Who knew these Kraang are so nasty," Anna observed.

"The Turtles did say they had enemies," Elsa reminded.

"Yeah but, I never thought that…"

Anna was interrupted when a Kraang blast went past them. They turned their attention to a small squad of Kraang droids.

"These are the ones who are allies with the ones known as the turtles," one Kraang observed.

"The ones who are turtles are that which is known as enemies of Kraang," another droid noted.

"Those that are known as allies to those who are enemies of Kraang, are also enemies of Kraang," another droid said.

"What did they say?" the ice queen asked.

"No clue," Anna admitted.

"I'm guessing 'were friends with turtles so we're their enemies?" Kristoff guessed.

"That is correct," one Kraang congratulated, "All enemies of Kraang will now be destroyed by Kraang."

They primed their blasters, only for the front two to be decapitated by shuriken thrown by Raph, who landed in front of his friends.

"Raph!" Anna called out. For once she was happy to see him.

"You freaks touch them, and I will slap you back to Dimension X!" Raph warned.

"One called Raphael," one Kraang observed, "Kraang has a solution for the one called Raphael."

From behind the Kraang, what appeared to be a giant blue, headless gorilla walked to the front. As if the other people besides Raph present hadn't had enough wide eyes already.

"Um, where's its head?" Kristoff answered.

A Kraang in its hovering pod flew in and landed in the neck.

"Bio-droid engaged," it announced.

The bio-droid then roared.

"Aw, sewer apples," Raph uttered.

The bio-droid then tackled Raph and both fell into the docks.

The droids opened fire on the other people. Elsa was quick to form an ice wall that blocked the blasts. This surprised all the Kraang present.

"Kraang, the eldest human female present has powers over that which is known as ice," one droid observed.

"This ability found in a human being is uncommon," another droid added.

"Kraang must scan the human female," a third droid declared.

That very same droid took out a device. It invisibly scanned Elsa behind the ice wall.

"Scan achieved. This human female may be proven useful in the status that is known as alive."

"Terminate the others," another droid added.

The droids opened fire and destroyed the ice wall.

Donnie had told the guards just to help the people get out of danger. He didn't have time to give them a crash course in the class "Kraang-busting". The guards complied leaving Donnie to fight off the droids alone.

He bashed and kicked all the droids that came near him. Though he soon found himself surrounded by all sides, each droid primed its blaster at him.

"One called, Donatello, prepare for that which is known as your termination," one of the Kraang said.

All Donnie could do now was close his eyes so he couldn't see it coming. He expected to hear Kraang fire, but what he did hear was metal breaking and bashing. He opened his eyes and they went wide at the sight before him.

All the droid bodies around him were in ruins, what could have done that so quickly? He got his answer in front of him.

"You should watch your surroundings more carefully, Donatello."

"Sensei?!" Donnie shouted, "How in the world did you get here?!"

"All will be explained, my son. But for now, we must turn the tide of this chaos," Splinter instructed.

"Agreed. We'll explain everything to you when we're done," Donnie promised.

The two leaped into battle.

The ship had been chasing Leo across the kingdom's rooftops, blasting and missing every shot, though a few came close.

Leo then jumped between two buildings and caught himself between them. The ship passed over him. He climbed back up and saw the ship stationary hovering. This was his chance, as he took out his grappling gun and shot the Kraang ship.

Once the hook made contact, the ship began to swerve and turn to get him off. Leo was lifted off the air, though he pushed the retracting button and zoomed straight for the ship.

From inside the Kraang ship, two were at the controls. They were enjoying the chaos happening down below. They were so caught up in the moment that they failed to notice Leo kick his way in through the top hatch. When they did it was too late.

Leo zoomed in and sliced both Kraang out of their stations. He jammed his blades into the controls. He began to move his swords like a joystick and discovered he now controlled the ship's direction.

Kristoff was wrestling with a Kraang droid. Despite the droid's weak apparent stature, it was physically stronger than him. He was losing greatly and felt like his arms could be torn off until Sven rammed the droid from behind and got it off him.

"Thanks, buddy," Kristoff thanked with a smile.

Sven then rubbed his head against his owner.

Anna wasn't having as much luck herself. She had found a pole and tried to whack the Kraang droid in front of her, but her attack did little more than phase it. She stubbornly hit the droid across the face until it grabbed the pole.

"Kraang finds you annoying."

The droid shoved her to the ground, Anna found herself crawling backward until backing into a broken droid body. No time to think, she grabbed its blaster to try and hit the droid with it like a blunt weapon, when she accidentally squeezed the trigger. It shot the droid's head off.

Anna looked down amazed at the advanced weapon, and that's when an idea formed in her head.

Two droids approached Elsa. She quickly used her powers to form ice spikes pointing at the droids. They simply broke through it with their kicks.

"What do you want?!" she shouted at them.

"That which is known as screaming," one of the droids answered.

That droid was decapitated a few seconds later. Its partner turned to who did it: Karai. Before that droid could respond, a chain wrapped around it before being tossed and slammed into the ground by Mikey.

"Aw ya! How's that ground taste, son?!" Mikey happily shouted.

"Not bad," Karai congratulated.

"Thanks, sis," Mikey replied.

Elsa's eyes went wide. Michelangelo had just called this girl in black and silver 'sis' and it came to her.

"Michelangelo!" she shouted, getting both their attention as she ran toward them, "Is this your sister?"

"Uh, Mikey? Who's this?" Karai asked.

"Well, uh…" Mikey began but was interrupted when two more Kraang droids from behind opened fire.

As the droids continued to shoot, a force from behind blasted them to pieces. The three looked on and saw Anna holding a Kraang blaster.

"Are you guys okay?" she asked as she went towards them.

"Anna?" Elsa said, "How did you?"

"Oh, this?" Anna replied with the Kraang blaster in hand, "It's easier to use, see?"

She pointed the blaster, but Karai quickly kicked it away.

"That is a weapon. Not a toy," she warned.

"Excuse me? Who are you?" the princess asked.

Mikey sensed tension forming and broke it up, "Okay introductions. Uh, Karai; Anna and Elsa. Elsa, Anna; Karai."

"Mikey, who are these girls?" Karai asked.

Before Mikey could answer, the Kraang scout ship flew above them heading straight for the harbor, catching the attention of the girls, Mikey, Kristoff, and Sven.

Raph was pinned down by the foot of the Kraang bio-droid. They too noticed the ship flying straight for the water, before crashing and exploding.

Leo landed right in between the two parties, getting the attention of those not on the docks.

"That's two ships for you, Leo," Karai congratulated.

Leo turned wide-eyed to his sister, "Karai?! How did you get here?!"

"Leo, who's that girl?" Kristoff asked the Turtle.

Before Leo could answer, another interruption took place.

"Hey, guys!?"

They heard Raph shout as he was still pinned to the ground, "A little help here!?"

They were about to provide a helping hand when Donnie came jumping in front of them, "Don't worry guys."

"'Don't worry'?!" they all shouted.

"Dude, Raph's about to get pummeled!" Mikey exclaimed.

"Aren't you supposed to be…" Leo tried to question.

"The Kraang have already begun to retreat, as for Raph…" Donnie began, smiling smugly, "Just wait."

The bio-droid was about to slam its gorilla-like fists in front of Raph when suddenly, a figure leaped in front of it and kicked it off of Raph. Raph looked up at his savior.

"SENSEI!" Raph, Leo, and Mikey shouted.

Elsa, Anna, Kristoff, and Sven all went wide-eyed at what just happened. A giant rat in a robe just showed up out of nowhere. Elsa's mind was rattling, but pieces began to form together. They said 'sensei', a giant humanoid rat; all made sense.

"Is that…?" she wondered out loud.

The bio-droid roared at Splinter as it charged at him. It swung its gorilla-like fists at him like a maniac, but Splinter appeared to avoid it with little effort.

Splinter quickly acquired a stray oar from a boat and swung it multiple times into the bio-droid, knocking it back.

The bio-droid quickly turned around and activated its "butt-cannons". It opened fire, and one bolt broke the oar in half. The bio-droid got back up.

"You are now in the state that is known as the state of no defense that is the state of defenseless," the Kraang observed.

"A ninja is never defenseless," Splinter warned.

He quickly flashed three kunai from his hands and threw them at the bio-droid, which made direct contact. The bio-droid roared in frustration.

Splinter then came charging in and dealt three jabs into the bio-droid's right arm-pit. After which, the arm fell completely off. He then kicked it across the chest, with the bio-droid landing at the edge of the docks. It launched two chainsaw cords from its chest at him.

"You will not trip me up so easily," Splinter stated as he used his bare hands to cut the cords, and in one fluent motion, grabbed the chainsaws and flung them back at the one-arm droid.

Splinter ran straight forward, and with his right hand, threw out his index and middle finger, stopping less than an inch before the bio-droid's chest. Then an unseen force sent the body flying multiple yards, deep into the harbor.

Everyone's eyes went wide. But the ninja's looks quickly faded, as they expected much from their master. The queen, princess, ice master, and reindeer also had their jaws drop. The five ninjas were the first to run onto the dock.

"Master Splinter, that was AWESOME!" Mikey exclaimed.

"Still the best!" Raph congratulated.

"That Kraang didn't know what hit him," Donnie said.

"Why am I not surprised?" Leo asked.

Their congratulations were halted by an 'ahem'. They turned their attention to Karai, with a not-too-happy look on her face.

They all smiled innocently, right before they were all slapped across the face in one motion.

"Don't ever scare me like that!" Karai chastised.

"Sorry," was all Leo could say at that moment.

"Scolding will have to wait," Splinter advised, "I fear this is neither the time nor place."

They all looked to see multiple citizens coming from behind the Arendell royals, and all could see the six warriors on the docks.

"We'd better get out of here," Karai advised.

"Wait for it," Mikey said.

The next thing that happened was instant cheering. The citizens behind all cheered for their heroes who had once again, saved them. Despite a six-foot-tall rat there, the people were still chanting and cheering for their heroes.

"Wow," Karai uttered, with wide eyes, "This is… wow."

"Indeed," Splinter added, quite surprised as well.

Elsa and Anna walked onto the docks as well. The former was the first to speak, "So, I guess you're Splinter right?"

Splinter turned to his sons, expecting an explanation.

"Come on inside, sensei," Leo told him, "It's kind of a long story."

Arendelle North Mountains

The remaining Kraang had retreated up the mountain. There were only five droids left, and they ended up carrying most of the naked Kraang with them. A few had to travel through the snow with their bare tentacles. They had lost. Unknown to them, however, they had someone following them.

Hans had escaped from the castle dungeon and had caught sight of what had happened in Arendelle. The Turtles were fighting dozens of what looked like metal men with pink slugs in their chests. He found these creatures to be disgusting, though at the same time, interesting. They were enemies of the Turtles, so they could be useful to his plot.

So he had been following them up the cold mountain ever since they retreated. Hans had kept his distance, quickly moving behind all the snow-covered evergreens, keeping out of sight.

The Kraang had made it to the large cave they emerged from some time ago. Once all the creatures were inside, Hans went to the wall just outside the cave and peered inside. What he saw shocked him beyond belief.

There were many more metal men throughout the cave working at various machinery that was foreign to him. What surprised him, however, was the sight of a humanoid wolf-like creature and a large fish with metal legs.

"Well?" Rahzar asked one of the Kraang.

"Kraang has failed to locate that which is known as the dimensional inducer. However, Kraang has confirmed the whereabouts of the ones called the Turtles," the droid surmised.

"And…?" Fishface queried, "Are they dead?"

"Negative. The ones called the Turtles have defeated that which is known as the search and destroy squad that is made for the purpose of searching and destroying ."

"Why am I not surprised?" Rahzar said, disappointed.

"In Kraang's defense," the droid began, "The ones called the Turtles received aid from the one known as Splinter, and the one called Karai."

That statement made Fishface and Rahzar look at each other with surprise.

"The overgrown rodent and the treacherous kunoichi are here too?!" Fishface exclaimed.

"Master Shredder is not going to like this," Rahzar replied, "We'd better…."

Before he could finish, he caught a whiff of something and began to smell the air.

"What is it?" Fishface asked.

"The Kraang were followed," Rahzar answered, "Someone is here."

Hans had hidden behind the wall, outside the cave. These creatures knew he was there. He had thought of running, but an idea formed in his head as two Kraang droids appeared in front of him, both aiming their blasters.

The two evil mutants then both saw the human being escorted by the two Kraang guards into the cave and the prince stood before the two.

"Why hello there," Hans greeted with a casual smile.

Soon, however, he found himself pinned to the cavern wall by Rahzar's massive claw.

"Who are you?" Rahzar demanded, flashing his other claw in a position ready to strike.

"And don't lie to us, because we'll know," Fishface added, brandishing his large balisword with the blade inches from Hans' throat.

"I'm a friend," the devious prince answered, "I can help you."

"'A friend'?" Rahzar queried, "We only just met. How do you think you can help us?"

"I couldn't help but overhear your conversation," Hans said, "You mentioned the Turtles."

"What do you know of the Turtles?" the mutant fish-man asked.

"Not a lot," Hans admitted, "But recently, they interfered in a little 'project' I had planned, and they have cost me a lot of pain. You too, however, are enemies of theirs, correct?"

The two mutants nodded.

"Then we have something in common. What's the old saying? 'The enemy of my enemy, is my friend?'" Hans proposed, "But, I promise. If you continue to attack this kingdom, I guarantee, the turtles won't be the only problem."

"What are you getting at?" Rahzar asked.

"If you will allow me to explain. Just hear me out, and you can decide what to do with me afterward."

Bradford and Xever turned to each other, thinking of what to do. It appeared as if the two could read each other's minds. They had been working together for so long, that they could just make eye contact and a few facial expressions just to tell what they were thinking. They both appeared to have come to a decision.

Rahzar released Hans, who had straightened himself up.

"Start talking," Rahzar demanded, to which Hans smiled.

Arendelle Castle, Throne Room

It was midday in Arendelle. The guards were helping to get the kingdom back in order from the Kraang assault, which was foiled due to Arendelle's newest heroes: the Ninja Turtles, with the aid of their sensei, Master Splinter, and the beautiful, but deadly, Karai.

Now the two newcomers are in the throne room of the castle , having been briefed on what had happened recently in the kingdom for the last three days. Both were surprised , to say the least .

"So let me get this straight," Karai began, "During a fight with the Kraang, you guys got zapped to this 'Arendelle' kingdom."

"Yep," Donnie answered.

"After which you met its queen, who just happens to have ice powers," the kunoichi continued, looking towards the said queen , sitting on her throne.

"Uh huh," Raph nodded.

"And you helped save her from a spoiled prince who tried to take over this place before, as well as a band of assassins."

"You got it, girl," Mikey replied, with a smile of pride.

"So in return, you were named the kingdom's heroes. Now everyone pretty much worships you."

"That pretty much sums it up," Leo said.

"Sounds like something you guys would do," Karai said.

"It would appear my sons have gotten into their usual amount of trouble in the three days they have been gone," Splinter cracked.

"Very funny, sensei," Raph uttered sarcastically.

"Why the heck didn't you call us? We were worried sick!" Karai exclaimed.

"Different world. It's kinda hard to get a signal," Donnie reminded.

"Right," Karai uttered.

"Master Splinter, right?" Elsa asked.

"Yes," Splinter replied to the ice queen.

"I must say it is an honor to meet you," Elsa greeted, bowing in respect, "Your sons have told us much about you."

"Have they now?" Splinter asked, looking at said sons.

"Only the good stuff," Mikey cracked, to which Anna giggled.

"I get you were once human," Kristoff began, " But, you're a lot taller than I thought you would be."

He wasn't wrong , Splinter was the tallest in the room. He would have to stand on the tips of his toes to be at an equal height with him.

"Yes, I do receive that comment a lot," the sensei replied.

"But you are amazing," Anna said, "You're faster than the Turtles. You took down that Kraang-gorilla-thing in less than a minute. It was just so ... just so..."

Anna couldn't finish for she was still so amazed.

"Yes," Elsa interrupted, avoiding an embarrassing first impression. She loved Anna, but she can be embarrassing sometimes, "It's pretty easy to see where the Turtles got their skills from."

"Thank you," Splinter replied, "You need not worry about your sister leaving an embarrassing first impression. It is quite the common reaction when one witnesses something they have yet to see before."

Elsa was a tad surprised that Splinter caught her intention so easily . This humanoid rat is good.

Anna's attention shifted to the other woman in the room. Something had been troubling the princess and she had to ask.

"So, um Karai," Anna began, getting the kunoichi's attention, "You're the Turtles' sister?"

"Yeah? What of it?" Karai asked.

"Well, it's just, I don't mean to sound rude or anything , but; they're turtles, and you're a normal girl."

"Yeah, and?" Karai urged for Anna to get to the point. She could tell the princess didn't know about her mutation and she wanted to keep it that way.

"When Mikey said he had a sister. I kinda thought she would be a, you know, a…"

"A Turtle?" Karai went straight to the point.

"Well, yeah."

"I am a tad surprised myself," Elsa added, "I was not expecting a normal girl."

"Well…"

"See, she's Splinter's biological daughter," Leo interrupted. "Before he mutated, he had her. We were adopted."

The Turtles' leader turned to Karai with a smile, indicating he had not told them about her situation, especially regarding him. That made Karai smile back as well.

"Oh, alright. That makes sense," Elsa replied.

"Hey, um, sorry about…." Anna apologized.

"Forget it. It's fine," Karai interrupted.

The group turned to the main door as it opened with Olaf running in.

"Hi everybody!" he greeted.

"There's a talking snowman," the ex-Foot Clan member deadpanned, "Why is there a talking snowman?"

" Oh that's Olaf , Elsa made him," Kristof answered, to which both Karai and Splinter turned to the queen.

"The power to create life," Splinter began, "What you possess , it is quite a beautiful gift."

"Thank you," she thanked with a smile. She liked how more and more people were now starting to like her powers.

"Umm, Anna," Olaf whispered, "Who's the giant rat and the pretty girl?"

"Oh, that's the Turtles' Master Splinter, and their sister Karai," she answered.

"But she's…" the confused snowman added.

"The Turtles were adopted. She was born before he was changed," Anna whispered.

"Oh."

The snowman replied before turning to the newcomers with open stick arms, "Well, hi Master Splinter. Hi Karai. I'm Olaf and I like warm hugs."

Karai and Splinter just gave curious looks to the snowman, the former looking toward Raph.

"Yeah, don't," Raph answered.

"Is there a problem with his mind or something?" Karai whispered to Leo.

"I don't know. And I don't want to," Leo whispered back.

"Getting back to the matter at hand," Splinter returned, "My sons, what you have done is commendable. I am proud of you for it. However, you cannot live here forever."

"We know Sensei," the blue-clad Turtle replied.

"Aside from taking down a spoiled-rich-kid," Donnie began, "It's been hard to get everything in order. We were sent here by accident, so it's going to be hard to try and repeat the process on purpose, and even harder to get it done right. We're gonna be in Arendelle for a while."

"I see," Splinter noted.

"Don't look so down, Master Splinter," Mikey said, "You're gonna love this place. It's awesome."

"Yeah, it's not too bad," Raph said, "Just so long as you ignore the common annoyance."

"I guess we don't have a choice, do we?" Karai surmised.

"Don't worry sis ," the Turtles' leader said, "You're gonna like it here."

Splinter realized that this was likely their only option. He was not quite fond of moving into new places, but then again, one must adapt to new surroundings, and these surroundings were quite pleasant. A lot more pleasant than the New York sewers.

"We would be honored to stay here," the humanoid rat said, which made the royalty sisters smile.

"This is gonna be great!" Anna beamed, taking Karai's hands, much to the warrior's surprise, "It's finally nice to meet another girl. We're gonna be great friends. I can tell already."

" Yeah , sure," Karai said.

"Well then, welcome to Arendelle," the queen of Arendelle welcomed.

--------------------------------------

New York City

It was once again quiet in the lair of the Shredder. He sat patiently on his throne awaiting the return of his two strongest henchmen. Alongside him was Tiger Claw, who also awaited their return, though he was getting a little impatient.

"Where are they?" Tiger Claw asked out loud.

"Patience, Tiger Claw. They'll be here," the Shredder assured.

Tiger Claw took a whiff of the air. He caught the scents of Rahzar and Fishface, as well as a Kraang droid; but he caught something else. It was the scent of a human, one unknown to him, he didn't like it. He stepped towards to double doors as they slid open.

Rahzar, Fishface, and the Kraang droid entered the throne room and stopped just a few feet away from the door.

"Well?" the Shredder asked.

"We found the Turtles," Rahzar answered.

"And?"

"They still live," the mutant dog replied.

The Foot Clan's leader slammed his fist on the arm of his throne.

"You have failed me. As you know, I do not tolerate failure."

"With all due respect, master," Fishface began, "The Turtles had help. We found out Splinter was there as well."

That caused him to narrow his eyes in anger and hate.

"And Karai,"

That made his eyes widen in surprise. The Shredder had taken Karai when she was a baby from that wretch and raised her as his own. He tried to mold her in his image and almost succeeded. The Turtles told her the truth and she left, which led to her getting mutated. He had been seeking her to get her to rejoin the Foot, with little success.

"But that's nothing."

Another voice sounded from behind the darkness of the door, and who stepped out of the shadows was none other than Hans.

"That is the least of your…." Hans began before a large blade came inches near his face, shutting him up. The former prince glimpsed at the blade's wielder, Tiger Claw.

"Bradford! Xever!" Tiger Claw snapped, "You dare bring an outsider here!?"

"Oh, believe me, Tiger Claw," Fishface began, "We had the same reaction as you, but we can assure you that he is quite interesting."

"I do not care how interesting you think he is. No outsiders enter the domain of the Foot Clan without the master's permission. You know this!"

"True," Rahzar affirmed, "But he has some intriguing information. You really should hear what he has to say."

"You shall…."

"Enough!" the Shredder yelled from the throne, getting all their attention, "Xever, Bradford, explain yourselves. Why have you brought this man into my domain?"

"Allow him to speak, Master Shredder," the humanoid canine began, "Normally, you wouldn't listen to anything if it doesn't involve the Turtles. But what this one has to say can be useful, especially in finally ridding the world of those insolent reptiles."

The Shredder thought about it for a moment. The mutant was correct. To him, everything else was a distraction from his war against Splinter and the Turtles.

He turned to the Kraang droid, remembering that he allied with them because he saw their usefulness and how they could help destroy the Turtles. He knew his servants would never betray or deceive him. If this man had information that could help kill his most hated enemies, then that too could be useful.

"Tiger Claw, let him speak," the Shredder ordered.

"As you wish master," Tiger Claw replied, sheathing his blade. Though Tiger Claw did not like the situation, he knew better than to question his master's orders.

Hans then walked close to the glass staircase leading to the throne. He looked up to the Shredder with a casual smile.

"Shredder, I presume."

"Who are you?" the Foot Clan's leader questioned.

"Oh goodness, where are my manners? I am Prince Hans of the Southern Isles," he greeted, bowing in respect.

"What do you want?"

"We may only have just met, but I can already tell we are much alike. I feel as though we are kindred spirits. Oh, there are differences to be sure, like the company we keep," he gestured to the three mutants and the alien behind him, "But underneath it all, we are both men of vision, able to see an opportunity and take it. Am I right?"

The Shredder merely glared at Hans. He wasn't really in the mood for small chatter.

"Right," the prince continued, though he could tell that this man ain't as persuasive as the many other people he met, "One thing we have in common is that we have both suffered and lost something. You don't have to tell me that you did. I see it in your eyes: hatred, pain. I have seen it in my reflection. Recently, I suffered a great deal of pain in the form of four human-sized turtles."

Hans clenched his fists, "An enemy, I no doubt, share with you."

"My warriors said you had information that could be useful to me, what is it?" the Shredder demanded.

Hans exhaled, for this won't be easy, "The Turtles have made a powerful ally. They are now in the kingdom of Arendelle, and have made friends with its queen, Elsa."

The Shredder could tell that this was the information he was getting to, "What use is this queen to me?"

The prince maintained his aura, "This is no ordinary queen, my friend. She has incredible and devastating power."

That caught the Shredder's attention.

"What kind of power?"

"She can create and control ice and snow."

"Hmph," Tiger Claw grunted, slightly interrupting their conversation, "We possess many devices with such power."

He took out one of his pistols and shot at the wall, creating a large patch of ice.

"Oh, I assure you, my one-eyed tiger. That is nothing compared to what Elsa can do."

Hans turned back to Shredder, "Her power is something to be reckoned with. She can create blizzards in an instant. She can freeze anything she touches instantly. But more so... fortresses made of ice, constructed in seconds. She even possesses the power to bring beings made of snow to life. Her power is so great, she sent her kingdom into an eternal winter, almost freezing it to the foundation."

Now it's getting really interesting.

"But her deadliest feat is that she can freeze a person's heart. I know it doesn't sound like much, but it is. When she strikes your heart, it's a death sentence. Your whole body will slowly and painfully freeze from the inside out. Once your heart is struck, don't bother seeking help. You're already dead," Hans finished, awaiting a reply.

The Shredder looked at his two mutant warriors, "Is this what he told you?"

"Yes, master," Fishface answered.

Shredder turned to Tiger Claw.

"He speaks the truth. I smell no deception from him."

"Kraang has that which is known as evidence to back up that which is known as the story that has been told by the one known as Hans," the Kraang droid added.

It took out a device and displayed a hologram of Elsa, from when they scanned her during the attack.

"The one known as Elsa possesses the power to manipulate that which is known as ice to the extent that is great, which is known to the great of the extension."

The Shredder was indeed intrigued. This power could be useful, very useful, "Very well then."

"Excuse me?" Hans asked.

"This information, this Ice Queen... it has piqued my interest. Her power is great, but such power should not be in the hands of such a child."

He looked at the hologram of the queen, "That power belongs to someone more worthy of it; one who can use it properly."

This surprised Hans. He expected Shredder to be afraid of Elsa after what he just told him.

"Are you sure? She is quite dangerous. Though she is loved in her kingdom now, they feared her when she froze it. They were terrified."

"Fear? I do not feel fear. I instill it."

Hans thought about this. It was interesting how someone could not feel fear, something else they now had in common. He smiled, this could be useful.

"However," Shredder got the prince's attention, "You would not come to me with this information without wanting something in return. So tell me, Hans, what is it that you want?"

Hans had to admit. This guy was not so easily fooled.

"You're good," he admitted, "There are a few things I do want in return; nothing too big I assure you. All I ask…"

Hans bowed onto one knee, "…is for a place in your organization and a front-row seat at seeing those Turtles die."

"Very well," the Shredder coldly replied.

"Master…" Tiger Claw began to object.

"Bradford, Xever."

"Yes Master Shredder?" they both answered.

"You will go with Hans, return to Arendelle, find me this 'Queen Elsa', and bring her to me," the Shredder instructed.

"And what of the Turtles?" Rahzar asked.

"Or Splinter? Or Karai?" Fishface added.

"If you encounter them, do what you must, but do not kill them," the Shredder answered.

" Don't kill them?" they both questioned. They understood why they could not kill Karai. But the Turtles and Splinter? He hated their guts and wanted them dead for a long time. Now he said they are NOT to be killed?

"You heard me," their master explained, "Once I have this magnificent power, the rat and his Turtles will be the first ones I shall slay with it."

That comment made both of the evil mutants smile.

"Now go."

The two evil mutants bowed, and they and Hans prepared to depart. Bradford and Xever left the room, but right before Hans could leave though….

"Hans."

The Shredder called out to the prince, causing him to stop right before the exit and not turn to face him.

"Do not think for a moment that you are truly a part of the Foot Clan, or that you have bartered your way here. You are merely an ally, nothing more. You must prove yourself before you are even considered worthy of the Foot. I am counting on you here, but do NOT betray me. If you do, then I promise, the consequences will be dire."

Hans felt a few drops of sweat flow down his face as he left the room.

The door closed. He stopped and exhaled deeply. What was this new sensation he was feeling? Was this, fear? Just being in the Shredder's presence made Hans feel it.

This man, what is he?

Chapter Text

Arendelle - Castle Courtyard

Karai stood in the middle of the courtyard, relaxed, and at ease. It would appear that way if someone didn't notice Raph standing several feet away to her left. The red-clad turtle stared down at his sister, sai brandished. To the kunoichi's left, stood Mikey, similarly mirroring Raph with his nunchucks.

Karai's eyes shifted between the two turtles, as she was rooted in the spot. Her hand slowly reached for her sword. As soon as her hand was at the handle, it had begun.

In one swift movement, Mikey swung his nunchucks and extended the chain, sending one end straight for her. She anticipated this. Quickly, she jumped to avoid it. He saw this coming and jumped up to try and bash her with his weapons. Karai, who had not even drawn her blade yet, had grabbed the orange-clad Turtle by the neck, and as they fell, she shifted their bodies so that his shell took the impact.

As soon as they landed, Raph lunged at her. Karai drew her blade, and the two warriors parried their weapons against each other. He was swinging his sai in every direction possible, while she for the most part was blocking. She avoided one attack by moving her head, quickly ducking and side-slashing him.

Mikey jumped from behind in an attempt to catch her by surprise. Karai saw this coming. She grabbed him by his arms and slammed him onto Raph. Both were defeated as Karai gave a smug grin.

"What's the matter? This place makes you guys soft?"

"You were lucky and you know it," Raph stated as he and Mikey both got up.

"Oh really?" she replied, "So it was luck's fault you tasted the floor?"

"Aw snap!" Mikey exclaimed, "She gotta ya, dawg."

Raph backhanded Mikey.

"Wow! You're amazing!"

All three ninjas turned to the source of the praise: Anna. She saw the whole sparring session from the main gate and wanted to see how good Karai was, she was not disappointed.

"Hmm, thanks," Karai replied.

Anna came running, and took the kunoichi's hands, much to the latter's displeasure.

"Come on, you gotta show more of your moves," Anna requested.

"Yeah, I don't think so."

"Aw come on! You're amazing, I wanna learn some of that ninjitsu stuff too."

"Why?"

"It could be fun."

Karai sighed, "You are a naive one, aren't you?"

"Excuse me, but what's that supposed to mean?" the princess asked, her mood becoming a bit sour.

This was going to get out of hand quickly. Surprisingly, Mikey was the first to notice, "Hey, Raph? You think we should do something?"

"Hey, I'm just enjoying the show," Raph said as he sat on the fountain, cross-legged, amused at the argument in progress.

"This stuff isn't fun. It's for fighting, even killing," Karai stated, "You really wanna do that?"

"Well… no, but…"

"Then ninjitsu is not for you."

"Okay, maybe not. So what do you want to do?"

"Right now, I just want to get cleaned up."

The warrior walked past her back to the castle.

"Okay… after that?" Anna asked.

"Why do you wanna know?"

"Well, we could hang out…"

"I'm not the type to 'hang out'."

"But…"

"Look. I know you wanna be friends and all that giddy stuff, but that's not me. I'm only here because my brothers and father are. You wanna be friends with someone, look somewhere else."

Karai then walked back into the castle.

"Ugh. What's her problem?" Anna asked.

"She's like that," Raph said.

"We did warn you," Mikey added.

"Has she always been this way for you guys?" Anna questioned.

"Yeah, for as long as we have known her," the red-clad Turtle answered.

"How do you put up with that?"

"You get used to it," Mikey stated, "Let's just say, her childhood was pretty rough."

"It's like Elsa all over again. Only, not as rude," the princess reminisced.

"Just give her time," the orange-clad Turtle consoled, "She'll open up eventually."

"I waited 18 years for Elsa. I think I can wait a bit for Karai," Anna declared.

"Why do you wanna be friends with her so bad?" Raph questioned.

"I just want to be, does there have to be a reason?" Anna said, "Well, I've been in this castle most of my life. I indeed know how to get out, but, it's just nice to meet another girl, that's all."

Raph sighed, knowing Anna was plenty stubborn. After hearing when Elsa froze Arendelle, he knew that once she set her mind to something, there was no stopping her.

"Well, good luck with that."

Within the castle walls, Karai was walking towards her guest room. She had to admit that Arendelle was nice. The castle was filled to the brim with rooms, and that didn't seem bad. It was kinda bad for her to brush off Anna like that, but her past wasn't something she liked to talk about. Not to mention it involved a certain someone the Turtles had yet to tell Elsa and Anna about, and she understood why she wanted to keep it that way, hoping that monster doesn't come here. This kingdom barely survived a Kraang attack, and if the Shredder attacked… there would be hell, which was the last thing she wanted for this world.

Her thoughts were interrupted when she heard a certain voice.

"Hey, Karai!"

She turned to Olaf, walking towards her, with a prepared hug.

"I'm just gonna go out and say this right now," she said, stopping the snowman, "I don't give hugs, and I don't even want one."

Olaf just stopped with his mouth hung open, his fragile mind wrapping around the idea of those words being used in a sentence like that, "But everyone wants a hug."

"I don't."

"Awwwww. Please."

"No."

Olaf flashed puppy-dog eyes, "Please!"

"NO!"

"Pleeeeeeaaaaaaaaaaaa…"

Karai resisted the ever-so-tempting urge to decapitate the snowman, even though she knew it would be futile as he would just reattach himself. Raph was right, this guy is annoying. Even more than Mikey. How did Elsa and Anna survive with him? She would never hope to know.

"Okay!" Karai shouted, much to Olaf's delight, "But just this once! One hug, that's it!"

Olaf then wrapped himself around Karai's legs. No way was she gonna hug him back. After about a minute, she decided that was enough.

"Okay, you can stop now."

"Just a little longer," Olaf said.

"Why do you like this so much?"

"I just love warm hugs."

Karai rolled her eyes and shook off the snowman. She then began to walk to her room, with the snowman following her. This is gonna be impossible.

The scene was noticed by Kristoff, Donnie, and Sven, who were out of Karai's sight at that point.

"She's a friendly one," Kristoff sarcastically remarked.

"You have no idea," Donnie added.

"And she's your sister?"

"Not biologically, but yes."

"Still, you live with her? Live with that attitude?"

"She isn't always like that. There are times when she's nice and great to be around."

"Yeah, I don't see it," Kristoff observed, with Sven nodding in agreement.

"She's been through a lot in her life. Some pretty intense things happened to her recently. Just give it some time."

"Okay, I'll take your word for it."

Karai had finally made it to her room. She was about to enter, only to find the snowman still following.

"Uh, you do know this is my room right?"

"Yes," Olaf said, with his smile.

"Meaning, it's time for you to go."

"Aw but I wanna talk some more," Olaf begged again.

"I need to get cleaned up, that should be enough of a reason," Karai responded.

"But…"

"Olaf," Elsa said as she walked up to the two, "Karai needs to rest. Can you please let her do that? I'm sure she can talk later."

"Oh, okay," Olaf said and walked away.

"Thanks," Karai thanked.

"You're welcome," Elsa began, "Sorry about Olaf."

"It's fine," Karai assured, "I live with Mikey, I think that's an achievement in itself."

Elsa giggled a bit, "I'm sorry if we made you upset or…"

"You didn't upset me or anything so don't worry about that."

"You just seem, a little… distant from everyone."

"It's not personal. It's just… I recently went through a 'transformation'. I'm still having trouble adjusting."

"I understand. Believe me, I do. If you need someone to talk to…"

"No. I just…" Karai sighed. She didn't know what to say, so she just entered her room and closed the door.

Elsa was about to knock but decided against it. She could sense that she was once in Karai's shoes and knew she needed space for a bit. This must have been what Anna felt like all those years.

The ice queen walked away, but she was soon greeted by Leo and Splinter.

"Did you guys, hear all that?" she asked.

"Yeah, we heard," Leo answered, "Don't worry, you'll be friends in no time"

Elsa smiled back at that remark, "I'll talk to her."

Inside Karai's room, she sat in her bed, deep in thought until she heard a knock on the door.

"It's me. Can I come in?"

"Leo?" Karai asked, "Sure come on in."

Leo entered and closed the door behind him.

"May I sit down?"

"What's stopping you?" Karai asked.

With that Leo sat in the bed next to her.

"Not what you expected?" Splinter asked the ice queen.

"When I first heard the Turtles had a sister, I expected her to be a little more… fun," Elsa confessed, "I mean, they're the most fun people, or turtles anyway, that I've met in a long time. So I just kinda…."

"It is alright," Splinter assured, "There are some people who open up to others instantly, and there are those who need more time. My daughter is one of them."

"I can sense, something happened to her recently," Elsa said.

"Yes. Something shattering."

"I know it's something personal, so I won't ask what it is. But when she's ready, I'll be there to listen."

"You have a caring heart, your majesty. There is much compassion and love deep inside. Hold on to that."

Elsa couldn't help but smile at the rat-like master. Leo was right; he was very wise.

"However, I can sense there is something else as well," Splinter added.

Elsa's expression dimmed a bit, "It's just… it wasn't that long ago, I was in a similar scenario."

"Leonardo told me your story. How you were born with magic powers, isolated yourself for years afraid of hurting those closest to you. Even after your kingdom found out, you left, all to protect them and your sister. However, someone entered your life, used Anna to his benefit, and because of him, you almost lost everything."

"That was mostly my fault," Elsa said, "Hans only took advantage of the situation, I was the one with the powers."

"But in the end, it was your love and your sister's love for you that saved you and your kingdom. But it wasn't just that, it was hope. The hope you both had at being close again as you once were years ago."

Elsa had regained her smile, "Now I know why your sons speak highly of you. I heard the stories, but listening to you, and being in your presence; it just, feels right. I feel I can talk to you about anything. I wonder if that's how Leo feels."

"I see you look up to him quite a bit."

"It's hard not to. He and his brothers have done so much; for me, for Anna, for my kingdom. Not just saving it, but, for being there; for being friends, that's something I never really had."

"You identify with them."

"Well, yeah. One of the reasons I opened up to them, was… I kinda felt like… no offense but…"

"You had been called a monster, and you could see they were in a similar situation, so in them, you saw kindred spirits; even more so in Leonardo, not just for being judged on the outside, but for him and you, both bearing the heavy responsibility of a leader."

"Yeah, that's what he told me."

Elsa had thought of Raph, Donnie, and Mikey as brothers, and had felt the same for Leo, but now she was feeling something else. The two could relate to each other more than anyone, it was hard to describe this feeling.

"For most of my life. I was afraid. My parents told me how dangerous my powers are; but I don't resent them for it, don't get me wrong. I know they loved me, and I loved them, but they said how dangerous and… they're not the only ones… I just… I…."

At that, Splinter had firmly put his hand on her shoulder. He looked her in the eye.

"You are who you choose to be. Not what others make you."

"Thank you."

She had to admit: Splinter was awesome.

Back in Karai's room. Leo and Karai sat in silence, which Leo was the first to break.

"You don't have to shut yourself out from them you know," Leo said.

"I know," Karai said, "It's just…"

"Your mutation? We didn't tell them about that, and we know you're getting it under control and…"

"It's not just that. These people seem nice. I kinda like them, I… I don't want to… tell them about…"

"How you were raised by Shredder?"

Karai nodded, "I know you didn't tell them about that. And I know why. The last thing we want is to get them involved with that psycho."

"Yeah. They already had enough trouble with that Hans creep."

"Yeah. From what you said, he was a pushover compared to Shredder. I kinda wish I was with you then. Just so I can beat the crap out of him."

"Why's that?"

"He may be a pushover, but he is still a dirtbag who needed a serious beatdown," Karai told her brother with a smile.

"You would have enjoyed that…."

Leo couldn't finish as there was an explosion that rocked the castle quite a bit.

This explosion caught the attention of everyone inside.

Mikey, Anna, and Raph could see smoke coming from the top of the roof of the castle.

"What the heck was that?!" Raph exclaimed.

Anna gasped, "Elsa!"

Anna ran inside to look for her sister, with Mikey and Raph following.

Splinter and Elsa were both knocked onto the floor but quickly got up. Leo and Karai ran out of the room.

"Father!' Karai exclaimed, helping Splinter up, "You okay?"

"I am fine," Splinter assured.

"You alright Elsa?" Leo asked the queen as he helped her up.

"Yeah, thanks, Leo," Elsa thanked.

"What was that?" Leo asked

"I don't know, but it can't be good," the kunoichi surmised.

"Agreed," Splinter replied.

Elsa just realized something that made her panic a bit, "Anna. I have to find her."

"Go," Splinter said, "Leonardo, Karai; go with Elsa, help her find everyone else."

"What about you, Sensei?" the leader asked.

"I am going to find what is causing this," Splinter answered.

"Just be careful," Karai stated.

Splinter nodded, as he ran down the hall; with the turtle, queen, and kunoichi going in the opposite direction

"Shouldn't we go with him and help?" Elsa asked, "I know we have to find Anna and everyone, but…"

"Don't worry," Leo said, mustering the utmost faith in his adoptive father, "Nothing can bring Master Splinter down."

Raph, Mikey, and Anna ran up the stairs of the castle, but once they reached the top, they happened to run into Donnie, Kristoff, and Sven.

"Kristoff!" Anna exclaimed as she embraced him, relieved he was safe, and he did the same.

"Dude, Donnie, what's going on?" Mikey asked.

"No idea," Donatello replied.

"Well, where's Sensei, or Leo, or Karai?" Raph also asked.

"Again, no idea, we're looking for them," Donnie stated.

"I think they're this way! Come on!" Anna urged as she ran further into the castle.

"Anna wait…" Kristoff tried.

"Relax, Kris, I got her," Mikey assired.

He was about to follow her, but Kristoff grabbed his arm.

"Mikey, I don't want anything happening to her! You got it?"

"Chillax, dude. Your girlfriend is safe with me," Mikey replied.

"You're sure?" Kristoff questioned.

"Dude, she's like my big sister. Ain't nothing happening to her on my watch," Mikey answered with every bit of seriousness.

"I'm trusting you with her life. Go."

Mikey nodded and ran after her.

"Come on, Romeo," Raph said, "We gotta get moving."

"Right."

The two turtles, reindeer, and ice miner ran back down the stairs.

Splinter had arrived on the roof of the castle through the large hole caused by the explosion. Once on it, he was completely surprised at what he saw.

Dozens of Foot-bots were crawling up the castle walls, with some busting windows and beginning to pour inside.

The sensei then heard multiple robotic noises behind him. He turned and saw at least twenty Foot-bot ninjas ready to attack. He was about to follow, but he quickly sensed something immediately wrong. Because of this, he jumped away and it was a good thing he did. He was quick to avoid a small pink laser blast.

Splinter looked up and saw the advanced Foot-bot, Chrome Dome—Mikey’s name for it—hovering on small rockets in its feet. The advanced robot looked at him.

"Target: Splinter," Chrome Dome assessed, "Threat assessment: dangerous. Recommendation: immediate termination."

With that, the drone produced a pink laser sword in one hand and a pink laser whip in the other.

Splinter looked back and saw all the standard Foot-bots ready to attack as well. He readied himself.

Leo, Karai, and Elsa had got into the ballroom where the queen had her first meeting with the Turtles.

"How are we supposed to find anyone in this huge palace?!" Karai exclaimed.

"I don't know," Leo said, "But if we don't find out what's going on…"

Before he could finish, however…

Elsa shouted as she formed an ice wall in front of Leo, "LOOK OUT!"

Good thing, as a spear had just pierced the wall and stopped. It would have pierced the Turtle weren't for the ice queen.

"Thanks," Leo said with a sigh.

"Thank her later. We got serious problems," Karai stated.

They all looked up, and saw multiple Foot-bots fall from the ceiling and quickly surround the three.

"The Foot!?" Leo exclaimed, "Here!?"

"How the hell did they find us!?" Karai exclaimed as well.

"You know these guys?" Elsa questioned.

Leo and Karai drew their respective blades ready to fight.

"Long story. We'll explain later," Leo told her.

"Right now, we have to fight. Just stay close to us. These guys are a major step up from the Kraang," Karai warned.

Elsa readied herself as well, her hands surging with her ice-magic.

The Foot-bots revealed their weapons as they slowly closed in on our heroes.

Raph, Donnie, Kristoff, and Sven burst into the room filled with paintings and statues. Once they got in, they were surprised at what they saw, more so for the Turtles.

"What are these guys?!" Kristoff wondered.

"Foot-bots?" Donnie added.

"First the Kraang, now these bozos? What's next?" Raph wondered aloud.

"Funny you should ask," a voice from above was heard.

All four looked up. From the chandelier hung the mutant Fishface.

"Uh… is that… a fish? With metal legs?" Kristoff questioned; with Sven giving a perplexed look.

"Ooohh crud," Raph said.

"Fishface," Donnie added.

"Imagine my luck," Fishface began, "Here I am looking for this ice queen, and I happen to run into my favorite reptiles."

Fishface then drew his balisword. Raph followed suit with his sai; Donnie his bo-staff; and Kristoff with his hatchets.

The Foot mutant then leaped from the chandelier and down towards the group.

Mikey and Anna were running through the halls, this one larger than the most, they turned a corner and ran into Olaf, who still had a smile on his face.

"Hi Mikey! Hi Anna! Why's everybody running?" Olaf asked.

"Olaf!" Anna exclaimed embracing him, "Thank goodness you're alright."

"If you wanted a hug, you should have just asked," the snowman said, completely oblivious to the danger around them.

"Hugs later! We got company! The really bad kind!" Mikey shouted pointing to the end of the hall.

They all looked at the 10 Foot-bots entering the hallway. Mikey immediately pulled out his nunchucks.

"Anna, stay behind me," Mikey warned.

"But I wanna help," Anna said.

"Now there's some enthusiasm," a voice said from behind the Foot-bots.

They moved aside to allow the dreaded first lieutenant of the Foot to pass through.

"I am going to enjoy snuffing it out," the dog-mutant said with an evil smile.

"Aw, man. Rahzar!?" Mikey said with terror.

Anna then cowered behind Mikey before the sight of the terrifying mutant.

"Ohhhh! Doggy!" Olaf exclaimed.

"Uh, Olaf? I don't think that's the kind of dog that wants a treat," Anna warned.

"Easy boy, easy," Mikey said, panicked, "Maybe I got a bone for you."

"Oh. You and that girl have many bones I can feast on," Rahzar said with sadism, causing Anna to gulp.

Chapter Text

Arendelle Castle, Ballroom

Leo continued to parry his blades against the many Foot-bots. He blocked their seemingly endless attacks until he, frustrated with blocking, threw his blades and sliced three bots in half. Then, he went on the offensive, decapitating one Foot-bot and diagonally slicing another that leaped from behind. Seeing two more approaching, he threw his sword like a javelin, impaling both. He quickly retrieved his sword and continued to fight.

Karai parried blades with the Foot-bots as well , only they were trying to defend themselves from her. Despite being human, her mutation gave her the agility and quickness of a serpent. She kicked one bot off its feet and then impaled it when it hit the ground. She then threw multiple shurikens behind her at four incoming Foot-bots, decapitating all of them. One tried to jab at her with a mace hand, only for her to quickly dodge it and slice off the hand , then the head.

Elsa was having more difficulty dealing with the Foot-bots approaching her. She was using her ice magic mostly for defense, rarely fighting with her powers. This may have been only the third time in her life she fought, the first being when the Duke of Weselton's guards tried to kill her, the second during the Kraang attack.

She threw her hands out, forming ice spikes on the floor pointing at the five incoming Foot-bots; they merely jumped over it. She was now starting to get worried. She formed several ice walls around the Foot-bots, only for them to smash their way through. If she wasn't scared before, she is now.

As the robots continued to approach her, they failed to notice Karai quickly zipping past all five of them in one instant. The next instant, their heads all fell to the ground. Elsa would have normally had a heart attack at seeing someone decapitated if she weren't completely confused at the sight of the Foot-bots 'bleeding' electricity.

"There's no reason to hold back with these guys," Karai told Elsa, "They're machines. They're not alive."

"Not alive? Is this some kind of magic?" Elsa asked, wondering how such a thing was even possible.

"Not really," Leo said as he landed in front of her, "We'll explain later, but right now we need you to fight."

"But I…"

"Look," Karai began, interrupting the queen, "I get you never really dealt with this kind of thing before, but these things are machines, they don't feel. They're not alive, so just go all out! Let it go!"

Elsa was a tad surprised but realized Karai was right. These things we're not human. They needed to be stopped . So with her hands surging with magic, she did what Karai said she should do: let it go. She threw her hands out to her left and five Foot-bots were completely frozen from a blast of ice. She threw her hands out to her right, and several ice shards shot out, tearing through four Foot-bots like tissue paper.

"Now that's more like it," the kunoichi noted with a smile .

"Come on, guys," Elsa said as she stood with Leo and Karai, with more Foot-bots entering the ballroom, "Why don't we show these 'Foot' that I don't take well to those who threaten my friends?"

"My thoughts exactly," Leo replied.

With that, more Foot-bots charged in. Leo and Karai yelled as they charged in at the enemy as well , and Elsa sent out more surges of Ice-magic.

Castle Gallery Room

One bot was decapitated by Kristoff's hatchet. One was about to strike him with a scythe in the back, but it got rammed to the wall by Sven and impaled with his horns. Kristoff took note of this.

"Thanks, buddy," Sven grunted with a smile in response , "I still can't believe these things aren't alive. What did you call them again?

"Foot-bots," Donnie replied as he blocked one with his staff.

Donnie then twirled his staff, swept the bot off its feet, and impaled it on the ground with the retractable blade at the end of the staff.

"What are they exactly?" Kristoff asked.

"Long story. Probably better suited to tell when we're not fighting for our lives," Donnie answered.

"Good point."

The three then saw Raph go flying smack into the painting of The Scream. He quickly shook his dizziness off, and jumped right out of the way of Fishface, just as one of the evil mutant's metal feet smashed the face on the painting.

Raph had his sais at the ready . Fishface , his balisword. After a few seconds of heated staring, they both charged at each other. They parried their respective weapons at each other. Raph was, for the most part, blocking against Fishface's relentless assault. The Fish had both his balisword and his metal feet at his disposal.

The fight was observed by Donnie, Sven, and Kristoff.

"And the Fish's story?" Kristoff asked.

"An evil mutant named Fishface. Again explanations after the fight," Donnie replied.

Raph jumped back onto a fancy bench, only for Fishface to leap high and deliver an axe-kick. Raph avoided this as well, while the bench broke in half.

"What the hell are you doing here, Xever!?" Raph demanded.

"That information is need-to-know. And right now, you don't," Fishface replied.

The mutant quickly noticed something in the back of his eye and quickly avoided a hatchet blade. Fishface jumped off the broken bench and avoided all the attacks from Kristoff. The mutant used the blade of his balisword to block the hatchet blades and look Kristoff in the eye.

"You got guts, amigo," Fishface applauded, "I'm going to enjoy ripping them out of you."

The fish mutant fell on his back, taking Kristoff with him. He used his metal legs to spring the ice master high into the air .

Kristoff saw the floor coming at him real quickly. Fortunately for him, Sven came running in and caught him on his back.

"Thanks, Sven. Always got my back," he said as he patted the reindeer's head, resulting in the reindeer licking his face.

Raph and Donnie were both in front of the two. Facing Fishface, they each had their weapons ready. The four heroes stared him down.

"Hm? You know what?" the mutant fish began, "After I fix myself up some turtle soup, I might just help myself to some deer-legs."

That resulted in an angry snort from Sven and a glare from Kristoff.

"He's a reindeer, you moron," Kristoff replied.

"Do I look like I care?" Fishface asked rhetorically.

"No, you look more like you're about to have the shell beaten out of you !" Raph declared.

"What he said," Donnie agreed.

Fishface growled and charged right at them.

Hallway

Anna hid behind Mikey, who was looking a tad bit scared himself. Hard not to be, considering there was a terrifying dog mutant, with many Foot-bots behind him. Olaf was present as well, still a smile glued to his face.

"You are looking good Rahzar ," Mikey said with a fake smile, "Lost some weight?"

Rahzar ignored his comment and sniffed the air.

"Mikey? Who or what is a 'Rahzar'?" Anna asked

"Bad guy. Really bad guy. My arch-enemy," Mikey answered.

"Your 'arch-enemy'?" Anna questioned

"It's complicated."

Rahzar finished sniffing the air.

"She's close," Rahzar said, "Foot-bots! Search the place. Find the ice queen."

The Foot-bots nodded in response and left the area in search of their target.

"'Ice queen'?" Anna questioned. She soon realized what he meant and her eyes went wide , "Elsa!? What do you want with my sister?!"

"'Sister, eh?" Rahzar noted as he brandished his claws, "Maybe if something happens to you, she'll come to me. Heheheh."

Anna gulped at the threat, but Mikey stood in front, nunchucks twirling, "You ain't touching Anna, dog breath! Plus her boyfriend would kill me if something happened to her."

"And I got a score to settle with you, Turtle," Rahzar stated.

He then leaped straight for Mikey, who had pushed Anna out of the way. Mikey had jumped out of Rahzar's path just as he landed.

"Booyakasha!" Mikey yelled as he charged.

He bashed Rahzar a couple of times with his nunchucks, but the mutant dog soon caught both his hands. He gulped before getting sent flying into knight armor by Rahzar's kick. He had just finished seeing stars to see claws coming right at him. Mikey quickly avoided it and was now stuck avoiding and dodging all of his opponent's slashes.

The fight was witnessed by Anna and Olaf, neither of them liking it.

"I have to stop this!" Olaf stated as he ran towards the fight.

" Olaf wait!" Anna called, but it was too late.

Olaf had just arrived at the fight. Rahzar had pinned Mikey to the wall with one claw, about to finish him off with the other unti l…

"Instead of fighting! Maybe we can talk about our feelings!"

Rahzar turned to the sound of the voice, and was completely dumbfounded at what he saw: a talking snow-man.

"Now, if something's made you angry…" Olaf began, "Let's just sit down and hug it all out , what do you say?

*SLASH!*

In less than a second, Olaf fell to pieces, literally. His head had been cut up, with each of his eyes, and mouth at different ends of the pile , even his carrot-nose had been diced.

" Oh look at that," the disembodied mouth of Olaf said, "I've been diced . That's new."

"I'm not even going to ask what  that  is about," Rahzar stated

This gave Mikey enough time to throw a smoke bomb at Rahzar's face, temporarily blinding him and forcing him to let go of Mikey. Mikey then delivered a roundhouse across the mutant canine's face.

"Thanks for the distraction, Olaf." Mikey thanked before leaping back in.

Anna just stood there.

"Huh. Guess Olaf can help out," she smiled, not waiting to see the look on Raph's face when he heard this.

Roof of the Castle

Splinter jumped and leaped, avoiding all the pink laser blasts from Chrome Dome. Any Foot-bot that tried to take Splinter by surprise ultimately failed. Splinter had drawn the bare from his staff and sliced the heads off each attacking Foot-bot, while at the same time, avoiding the eye blasts from the hovering Chrome Dome.

Having had enough of simply dodging, Splinter took a blade of a fallen Foot-bot and quickly threw it into the head of the robot, right between the eyes.

Chrome Dome flew out of control, before smashing onto the roof. Splinter stood ready, knowing it was not over.

He was right; Chrome Dome stood back up and removed the blade from its head , sparks sparked from the head, and its eyes were badly damaged .

"Damage assessment…" Chrome Dome began, "Extensive damage to optic units. Calibrating. Switching to infrared vision."

The advanced robot's point-of-view changed to heat-signature, thus enabling it to see Splinter.

"Target confirmed: Splinter. Commencing termination."

"I will not be easily terminated ," Splinter declared.

Chrome Dome drew its pink laser whip and proceeded to attack the mutant rat. Splinter was able to block all the lashes with his blade , he then quickly charged in. Before the robot could react, Splinter sliced upward, severing the robot's right arm. Splinter delivered a kick to the chest, knocking the drone back several feet.

The drone then responded by drawing its pink laser sword and flew right at Splinter. The two locked blades while briefly glaring at each other.

Ballroom

Leo hacked and slashed at any and every Foot-bot he laid his eyes on. Karai did as well. Elsa kept freezing every Foot-bot in sight, to the point where it shattered. But no matter how hard they tried, more and more just kept coming.

The three found themselves completely circled and surrounded by at least 30 of them.

"It's like an endless wave of these guys!" Leo exclaimed.

"Where do they keep coming from?!" Karai yelled as well.

Elsa tried to think of something. She took note of all the robots surrounding them, then to Karai and Leo, then to the open main door and the outside hall was completely clear . An idea formed in her head.

"Leo, Karai. I need you two to get out of the room."

"What!? No way! We're not leaving you!" Leo contradicted.

"You wouldn't last ten seconds by yourself!" Karai added.

"I have an idea. I got a plan to stop these guys, but I need you both out of the room," Elsa explained.

The bots slowly came closer and closer.

"What are you planning to do?" Leo asked.

"There's no time to explain, just go!"

"But…" Leo began.

"Leo, do you trust me?" the queen asked.

"Of course I do," the Turtles' leader answered

"Then take your sister and leave the room, close the door behind you, and don't open it till I say so," Elsa told him.

Leo would never abandon his friends, especially to the Foot. But he saw the determination in Elsa's eyes and recognized it as the same he always saw in his brothers' eyes. He knew there would be no stopping her when she had that look.

"Okay. Karai, let's go."

"Yeah, sure," Karai said half-heartedly.

She hated abandoning people too , but if Leo agreed with this plan, then she knew it was going to work, but that didn't mean she liked it.

The two ninjas then jumped onto the Foot-bots and ran across the room on top of their heads. The two made it to the door and left the room closing it from behind. Both set their bodies against the door, trying to prevent the Foot from getting out as they were banging on it.

"Leo, are you sure about this?" Karai questioned

"I'm sure," Leo answered, giving her a look of confidence, "It's not like how she was years ago, scared and unable to control her powers. She knows what they are and how to use them. She's not as helpless as you think."

Back inside the room, the Foot-bots slowly made their way towards the ice queen. She gave a small wonder why they didn't attack her yet. Unknown to her, their master had ordered them to bring her to him alive.

No time to worry about why right now. Now that she was alone, she didn't have to worry about her friends and restraining herself.

She stomped on the ground, causing the floor to freeze. All the Foot-bots slipped and fell on the floor. She now had the time she needed. She concentrated all her power into her hands, surging with a massive amount of ice magic. A white, light-blue, pulsating, orb formed in her hands , it quickly grew to the size of a bowling ball.

The Foot-bots had now gotten up. With a yell, Elsa threw out her arms and the orb exploded in a massive flurry of white that completely engulfed the entire ballroom.

Leo and Karai both felt a massive shockwave slam against the door, almost knocking both of them off their feet.

And then … all sounds have stopped.

The two quickly regained their footing and looked at each other, both of them wondering what just happened.

"Okay!" they heard Elsa shout from behind the door, "You guys can come in now!"

Both looked at each other, neither of them not knowing what to expect, so they both slowly opened the door, and we were completely unprepared for what they saw.

The ballroom was completely white. Every bit of it: the walls, the ceiling, the pillars, the floor were all completely covered in snow. The snow on the floor was completely flat, it looked like it froze the room itself.

Even more surprising, we're the Foot-bots. All completely white, and looking like the victims of a nuclear explosion. Instead of being turned to gray ash statues, they were white with snow. With a light snow flurry from the ceiling to complete the deal.

And right in the center of the room, was none other than Elsa, just standing there with her hand on her hip, a smug smile, and looking pretty.

"Well?" she began with a cocky smile, "What do you think?"

Both ninjas had their mouths hung open, unable to find any words to describe the situation. Elsa took their silence as saying that they were impressed. She then tapped the forehead of a frozen Foot-bot, then it shattered like fragile ice. All the other frozen Foot-bots followed as well,

"I told you I had a plan," Elsa said.

"I'll say this…." Karai began, "You are  no  damsel in distress."

"No. She puts her   enemies  in distress," Leo commented.

Fishface had just been sent flying through the door from the art gallery. He rolled along the floor of the hallway , before sliding to a stop on his feet. He got up to see two turtles, an armed ice miner, and a ticked-off reindeer all glaring at him.

"What's the matter Calamari-boy?" Raph teased, "Having trouble keeping up?"

" Technically he's a carp," Donnie began to correct, resulting in an eye-roll from Raph and Sven, "And calamari is squid, so he's not really…"

"Donnie. Now's not the time for that," Kristoff interrupted.

"Thank you!" Raph said, glad someone else caught notice of Donnie's scientific blabbermouth, "You can't beat us all, Fishface. Give up now."

Xever knew Raph was right. During that fight, he was mostly blocking and avoiding sais, staffs, hatchets, and even a few antlers. There was no opportunity for him to fight back.

Fishface growled, "Damn it."

He then took off running down the hall, his mechanical legs giving him a speed boost.

" Hey get back here!" Donnie demanded.

"Yeah, the dance ain't over yet!" Raph added.

The two turtles chased him down the hall.

Kristoff got up on top of Sven, "You in the mood for some fish tonight Sven ?"

Sven then gave a determined look before running off with the turtles.

Mikey was thrown against the wall, glaring at the one who threw him.

"It's so simple, even  you  can get it," Rahzar began, "Tell me where the ice queen is, and the pain will stop."

Mikey simply stuck out his tongue at Rahzar. The dog mutant glared at him, ready to slash his face off, only for a sword to be swung in front of him.

Rahzar stepped back a little, and Anna stood in between the two mutants with a sword in hand, glaring at the mutant dog.

"Anna?" Mikey began, "Where did you get that sword?"

"Found it," Anna replied simply . She took it from one of the knight armors in the hall.

"Do you know how to use a sword?"

Anna's look of determination gave way a little.

"Uh… no not really," though she regained the look, "But it can't be too hard, right?"

Before Mikey could answer she swung the sword at Rahzar, who made little effort to avoid it. Anna tried to swing the sword at the evil mutant, but it looked more like a little kid swinging a baseball bat. As Rahzar barely tried to avoid the attacks, he gave a look that silently asked, "She's not serious, is she?"

Anna tried to swing downward, only for Rahzar to catch the sword with his bone claw.

"A piece of advice, girl," he began, looking into her eyes with an evil smile, "If you're going to bring a weapon into battle…."

He then threw the sword out of her hands and kicked her across the floor.

"… learn how to use it right," Rahzar finished.

The evil mutant raised his claw, ready to finish her, only for a chain to wrap around it, surprising him. He turned to see Mikey with an extended chain from his nunchuck.

"Dude," Mikey began, "Didn't Momma-Rahzar tell you it ain't nice to hit a princess?"

He then swung the chain and sent Rahzar flying out the nearest window.

"You okay, Anna?" Mikey asked as he helped her up.

"Yeah. Thanks a lot," she said with a relieved smile.

"Hey, where's Olaf?" Mikey questioned.

"Trying to put himself back together," Anna replied.

Olaf's body seemed to put itself back together, save for the head , which it was now searching for, though the carrot nose remained diced.

"Hey, body! I'm over here!" Olaf said from his head.

The body then turned in the direction of the voice, its stick-arms out-stretched like someone trying to find their way in the dark.

"Follow the sound of my voice. You're getting warmer."

Castle Courtyard

Elsa, Leo, and Karai came running outside.

"This is where I last saw her. With Mikey and Raph," Karai answered Elsa, who was deeply worried for her younger sister.

"Anna must have gone inside," the ice queen theorized.

"Then we better…" Leo began but was interrupted by the sound of shattering glass.

They looked up and were completely surprised at what they saw: Rahzar sent flying from the window.

The dog mutant landed hard on the ground but managed to get back up. "Damn that turtle," he said, before turning and catching a look at our three heroes.

"What in the world is that?!" Elsa exclaimed, never seeing a creature so horrifying before.

"Bradford?!" Karai exclaimed.

"If he's here…." Leo wondered before a look of terror fell on his face, "Oh no."

Rahzar caught a weird scent coming from the woman in the light blue dress. The fancy clothing gave him an idea of who she was, and she looked a lot like the princess he just ran into. He smiled evilly.

The mutant canine leaped from his location, the unprepared trio still caught by surprise that he was in Arendelle. He slapped Leo and Karai out of the way, before pinning the frightened queen to the ground with his massive claw.

He lifted her to eye level, her legs dangling from lack of contact with the ground. He sniffed her briefly. Elsa was scared beyond belief.

"Your scent is very unique," Rahzar began, "You smell much like that princess, and she said 'sister '. "

"'Princess'?" Elsa wondered before panic filled her eyes, "Anna?! Where is she?! What did you do to her?!"

Ignoring her question, Rahzar continued, "More to it than that. Your scent has a frosty touch to it. You're the ice queen, Elsa of Arendelle, aren't you?"

"How do you know my name?"

"I'm not going to kill you if that's what you're wondering. My master is looking forward to meeting you."

Elsa was both terrified and confused, not knowing what this creature was talking about. She wouldn't have to worry about that, as Leo delivered a kick to Rahzar's back, forcing him to let her go.

Rahzar was knocked back several feet, and Leo stood in front of Elsa. "Tell him Elsa is off-limits!"

Karai stood with Leo as well.

Rahzar was set and ready to fight until he saw Fishface jump from another window. His mechanical legs gave the mutant fish quite the jump as he landed next to his partner.

"And now Xever to complete the set," Karai noted.

"That pretty much confirms it," Leo added.  He  has found them.

"Let me guess, amigo," Fishface questioned his partner, "The one in the dress is the ice queen?"

"Yep, that's her," Rahzar answered, "Looks like our job is just about done."

"You would think so but …" Fishface began, till they heard yelling and running from the main gate to the castle.

Leo, Karai, and Elsa all turned to Raph, Donnie, and Kristoff on top of Sven, all running and meeting up with the three.

"You guys okay?" Donnie asked, before taking a look at the enemy in front and looking in surprise.

"What the hell is Rahzar doing here?!" Raph exclaimed.

"'Rahzar'?" Kristoff questioned, looking at the monstrous dog-like mutant for the first time, "That thing has a name?"

This earned a growl from the mutant.

From the window where Rahzar was thrown out , Mikey jumped out, carrying Anna with him. He landed safely on the ground and set Anna down near the rest of the heroes.

"Elsa! Kristoff!" she exclaimed.

Both turned and were glad to see Anna safe, but the latter's smile of relief turned to shock once her eyes saw Rahzar still alive, and then confusion at the sight of Fishface.

"Um, Mikey? Why is there a fish with metal legs?"

"That's Fishface," Mikey answered, "Another bad guy."

"Well, things are certainly getting interesting," Fishface noted, but soon heard a crashing sound from behind.

All turned to the sound and saw the fountain completely broken. However, what was even more surprising, was Chrome Dome, or what was left of him, sparing before completely shutting down.

"That is a matter of perspective!" a voice boomed, and all turned to the roof of the castle .

The heroes were all relieved at who they saw: Master Splinter, with a strong look of determination.

"Sensei!" the turtles exclaimed.

"Father!" Karai exclaimed as well.

Elsa, Anna, and Kristoff all smiled as well.

In a single bound, Splinter leaped and landed in front of the heroes, facing the two evil mutants.

"You two are not welcome here," he declared, pointing his staff at them, "Leave! NOW!"

Fishface and Rahzar glared at the rat before hearing the sound of people yelling and running behind them. They turned behind and saw at least 15 of Arendelle's royal guard pointing their cross-bows at them. Normally the guards would have freaked at the sight of mutants like them, but having allied with giant turtles and giant rats, and fighting brain-squids in metal bodies, they quickly got used to this sort of thing.

"Halt!" the captain shouted to the two villains, "You two will surrender at once! There is no chance of escape!"

Rahzar and Fishface quickly assessed the situation. They could likely handle the guards, but the Turtles and Karai were another story, and they  knew  they didn't stand a chance against Splinter. Even more so, they didn't know the extent of Elsa's powers. She was not only their target, but an unpredictable wild card.

"Time to leave," Rahzar stated.

To this, Fishface took out something.

"Have a whiff of poison! Turtle scum!" Fishface slammed the object to the ground.

It was a smoke bomb laced with poison. A green cloud quickly formed and grew.

The Turtles moved Elsa and Anna back away from the cloud, Sven carried Kristoff, still riding on him, away, and Splinter helped Karai back.

"Stop them!" the guard captain shouted, and the guards were about to run to the cloud.

"STOP!" Splinter shouted, "That cloud is poisonous! Do not go near it!"

"I'll handle it!" Elsa declared.

She then quickly formed a massive ice dome, completely encasing the cloud in the ice. It would dissipate soon from the lack of air in the insolated ice dome.

Unknown to them, Rahzar and Fishface had leaped onto the roof, away from the heroes, and jumped into the water, escaping.

"Is everyone alright?" Raph questioned, receiving confirmation from everyone present.

"This is bad," Leo noted, "This is very, very bad."

"I know," Mikey agreed, "How did those two even get here?"

"The Kraang must have helped them," Donnie suggested.

"Wait," Elsa said, getting the Turtles' attention, "That creature, that dog-thing…."

"Rahzar?" Mikey finished for Elsa.

"Yes, him. He said…"

"Elsa?" Anna asked.

"He said, 'his 'master' wanted to see me.'"

Once that was said, the otherworld heroes all looked at each other in shock.

"He has found us," Splinter said.

"We kinda figured that out, sensei," Leo told him.

"You guys know who this 'master' is?" Anna asked the mutants.

"How could he have found us?" Donnie questioned, not hearing Anna's question.

"More importantly, how did he find out about Elsa?" Karai wondered as well.

"Um...guys?" Kristoff said

"Dudes, this has gone from bad to worse in like record time," Mikey observed.

"Guys?" Anna said, trying to get their attention.

"I'm not gonna lie , I had a gut feeling he would find out eventually," Raph confessed, ignoring the others.

"Guys?!" Elsa exclaimed, but to no avail.

"If he's here, Arendelle is in the worst kind of trouble," Leo stated.

"GUYS?!" Elsa, Anna, and Kristoff all yelled, with Sven snorting loudly as well .

"WHAT!?" Leo, Raph, Karai, Donnie, and Mikey all yelled back.

"What is going on?" Elsa questioned, with a look of impatience on her face.

"Who were those guys? Who's this 'master' guy you're talking about?" Kristoff questioned.

"What does all this have to do with my sister?" Anna asked as well.

The six mutants all looked at each other. They had to tell them now. There was no escaping it. They hoped they would never have to talk about him , but now it appears they have to.  He  has arrived .

"Come on inside," Leo said, "It's a long story, and believe me, this story is one you are NOT going to like."

Chapter Text

Arendelle Castle, Throne Room

Elsa sat on her throne, with Anna and Kristoff sitting on her right, Sven with them of course. Olaf was on Elsa's left. The snowman could not contain his excitement about a story that was about to be told. Splinter, Karai, and the Turtles were standing in front of them.

There was silence at first, Elsa was the first to break it.

"You know who attacked us," the queen spoke.

To which the six ninja masters exhaled, really hoping they wouldn't have to come to this.

"Yes," Splinter answered, "The ones who attacked your castle are the Foot, a dangerous ninja clan, and an even more dangerous enemy."

"The Foot?" Elsa asked.

"You four told us about some of your adventures," Kristoff recalled to the Turtles, "But you never said anything about this 'Foot'."

"We didn't think we had to," Leo began, "We never thought they would follow us here, much less attack you guys."

"But why?" Anna asked, "Why would they attack us? Why didn't you guys say anything before?"

"Primarily because we didn't want to scare you," Donnie replied.

"Scare us?" the ice queen questioned.

"Compared to those Brain-Squid things, I don't think we can…" Kristoff started but was interrupted.

"The Kraang we're one thing," Raph interrupted, "These guys are a WHOLE different ball game."

"I but those guys could use a hug," Olaf said, much to the Turtles and Karai's annoyance.

"I'm sorry, but were you NOT diced into pieces a few hours ago by them?" Karai questioned.

"I think we're getting a bit off-track," Elsa began, "Since they've made themselves known in my kingdom, I think we should know more about them should they attack again."

The Turtles and Karai grimaced at that, while Splinter merely sighed.

"Look, Elsa," Mikey said, "You guys don't wanna know what they're all about."

"Just tell us already!" Anna exclaimed, much to Elsa and Kristoff's suspense. It was rare to see such a reaction from her, "That 'Rahzar' guy said he wanted my sister. I want to know why!"

"My sons and daughter," Splinter said, "You're right to be weary of telling them this, but the princess is correct. The Foot have set their sights on Arendelle, as the queen, Elsa, has a right to know."

"Is it because we're friends with all of you?" Kristoff questioned

"Is that the reason they attacked us?" Elsa asked as well.

Splinter sighed as he began to tell the story, "I am afraid it goes much deeper than just that."

"Centuries ago in Japan, there were many ninja clans. However, there were two that stood above all others in terms of both strength and numbers. The clan of my ancestry, the Hamato, and the enemy, the Foot. The Hamato clan was based on honor with a strong belief in equality and justice. The Foot lived by the code that only the strong survive, and the weak perish. Because of their opposite natures, the clans engaged in a bitter feud that lasted centuries."

"So you're saying your ancestors were at war with these Foot-guys for a long time," Kristoff surmised.

The rat sensei continued, "Indeed. Almost sixty years ago, the feud had met its end. In an attempt to stop the bloodshed, the Hamato clan launched on final attack on the Foot."

This got Elsa, Anna, Kristof, Olaf, and even Sven interested.

"The battle was great. Much blood was shed, and many met their untimely demise. Finally, the dust had settled, and the victor came to the Hamato. After the fighting was done, a Hamato ninja, my father, heard a cry. He found the source of this cry was a near infant child."

This shocked the royalty.

"A baby?" Anna asked, "Why was there a baby there?!"

Elsa had a face of concern. The battlefield was no place for a child.

"It was unclear why the baby was present, but what  was  clear, was the child had been orphaned, his parents had died in the battle."

The sisters both had looks of sympathy.

"However, the child was of Foot ancestry."

That got all their attention.

"A Foot baby?" Elsa asked, "If he was from the Foot, and your father found him, did he…"

"Kill him?" Splinter finished for her, "No he did not."

They breathed a sigh of relief.

"He may have been the son of the enemy, but he was just a child, innocent of the conflict. Feeling sympathetic for the poor child, my Father took him in and sheltered him. He was raised in the house, as my adoptive brother. The child's name... was Oroku Saki."

Hearing that name made Leo, Karai, Raph, Donnie, and Mikey all shudder and clench their fists. This was noticed by their friends.

"Why are you getting upset?" Elsa asked.

"The baby has found a home, that's a good thing," Anna said with a smile on her face

"Sure his parents were killed, but he still found a family," Kristoff added.

"Sounds like a happy ending," Olaf stated

"It ain't done yet. Keep listening and you'll know  this  one ain't got a happy ending," Raph told them.

Splinter added, "To continue, Oroku Saki and I were raised as brothers. As we grew and trained in the art of ninjitsu we became rivals in virtually everything."

A small smile formed on Splinter's face, "A trait you no doubt have witnessed in your time with my sons."

The Frozen cast all giggled and snickered at this.

The rat master's smile soon faded, "We grew up together. A friendly rivalry emerged in nearly every part of our lives. As we both grew into young men, we even both fell in love at the same time, with the same woman."

If the audience wasn't interested before, they were now. Especially Anna and Elsa

"Her name was Tang Shen. She was kind, compassionate, beautiful, intelligent, and strong. Heh, she had quite the temper as well."

Anna giggled at that. Elsa smiled but caught a glimpse of Karai who was looking away, to which she looked in concern.

"However, a rivalry had formed between Oroku Saki and myself over her attention. At first, it started as a friendly rivalry, not too different from normal. But it soon became bitter and much more intense, especially for Saki. He believed I had beaten him in most things, and declared he would not lose to me here."

"So it wasn't for her attention. He did it just to try and beat you," Kristoff said

"It was a bit of both. He had developed feelings for her  and  sought to best me here. Soon, Tang Shen had become aware of how we both felt about her, she knew she cared for both of us and had to make a choice. Ultimately, she had chosen me."

Anna and Elsa both smiled at this, thinking romance was the main core of this story. Oh, how they were both wrong.

"As you can imagine, that did not sit well with Saki. Our rivalry had become far more bitter at that point. Jealousy had grown greatly in his heart and quickly spread throughout his being like a poison. One day he insulted me in front of her. He called me many things. Many hurtful and offensive things."

He sighed before he kept going, "I felt I could not let those insults go unanswered. I lost my temper, and I struck him, hard."

This shocked the royalty.

"At that moment, Oroku Saki had severed whatever ties had remained between us, shattering the bonds of our brotherhood."

"That's quite the falling out," Kristoff observed.

Elsa and Anna both looked at each other, it wasn't too long ago they almost had a falling out themselves.

"Still, he ended your relationship just because he couldn't get the girl?" the ice miner questioned

"It was more than that. Oroku Saki had been jealous of me for many years. Instead of expressing his emotions, he kept them all bottled up inside him. The more he kept them in, the greater they grew."

Elsa shuddered. It was the same thing for her; only for her, it was fear, not envy. Nonetheless, she allowed Splinter to keep going but was starting to like this story less and less. The same goes for Anna and Kristoff. Even Sven had a bad feeling. Olaf was still oblivious as always.

"A few years had passed since that incident, and Tang Shen and I were married. As well, we had a beautiful baby daughter." Splinter smiled as he put his hand on Karai's shoulder. She looked up and smiled at her father.

The Arendelle residence had smiled at this, but Elsa got a bad feeling about what was coming next. It confirmed her suspicions when she saw the Turtles with looks of near grief and anger at what was to come next.

"That happiness, however, was not to last. During this time, Oroku Saki had discovered his true heritage as a descendant of the Foot Clan. At that moment, all envy in his body ceased to be, and in its place was spawned rage and hatred. He had believed his true family to have been murdered. He discovered the feud that had existed between the Hamato and the Foot, and he had sworn vengeance."

Anna held Kristoff's hand rather tightly, a bad feeling sinking inside both of them. The same goes for the ice queen.

"He had gathered many ninjas across the land. He also recruited many criminals: thieves, mercenaries, assassins, and murderers. He demanded their allegiance and obedience. When they refused, Oroku Saki showed his strength, by taking them on by himself."

The audience was now looking in shock.  He took them on by himself?!

"Oroku Saki had trained in combat most of his life. He had bested all of them in battle. Few could lay so much as a single scratch on him. He had even crippled and killed a few of them to demonstrate his ruthlessness."

Shock in the royals had grown larger.

"At the sight of his strength and mercilessness, they bowed to him out of both respect and fear. Oroku Saki had rebuilt the Foot clan. He was given the title that is bestowed from generation to generation for each leader. A name that would strike terror into the hearts of even the strongest of warriors, a name that was only spoken in whispers… and the name they all whispered was…. The Shredder."

That name had made the Turtles, especially Karai, clench their fists in contempt.

"'Shredder'" Olaf said, "Sounds nice."

Donnie, Mikey, and Raph all stumbled back dramatically after hearing that.

"What?" Olaf questioned, only to have Raph come up in his face.

"'SOUNDS NICE!?'" the red-clad Turtle exclaimed, "Do you have any idea how NOT nice that is!?"

Raph poked Olaf in the head rather viciously.

"Hold on Raph!" Leo said, putting his head on Raph's shoulder, "Let Splinter finish"

Raph sighed and he withdrew from the oblivious snowman.

This was unnoticed by Anna and Kristoff, both were looking at each other in concern. Anna held Kristoff's hand even tighter.

Elsa was a different story. Hearing that the name Shredder had for some reason made her heart race. She began to shake in nervousness. Why? This was the first time she heard that name, and it already scared her.

Regardless Splinter continued, "One night, almost 16 years ago, Shredder had launched an attack on the Hamato clan. However, when the newly resurrected Foot Clan struck it was not a battle… it was a slaughter. The Hamato clan was completely unprepared for such an attack, and despite their best efforts, they were overwhelmed. It was not just the warriors, but innocents, elders, and even children; all butchered at their hands. This was not an attack, but a massacre; one that was intended to wipe the Hamato clan from the face of the Earth."

Anna had covered her mouth in shock with her free hand, and Kristoff looked in shock as well. Even Sven looked surprised. Elsa clenched the arms of her chair, her heart racing even more.

"In that night, Shredder sought to end me himself," Splinter continued, "He came into my home. Tang Shen and I tried to reason with him, but when I saw his eyes, I saw nothing of the man I once called my brother. I no longer saw Oroku Saki, only the Shredder. I knew he was beyond reason. He struck, and he struck hard. I had done what I could to defend myself, but I stood little chance against him. He pinned me down, ready to finish me, but before the blow could be met…. Tang Shen had… jumped in his way… he struck her instead."  

Elsa covered her mouth with both her hands at that.

Splinter quickly regained his composure, "Shredder blamed me, his rage and hatred had burnt to the highest possible extent. In his fury he burnt my home to the ground and left me for dead, buried in the rubble. But my suffering would not end there. The flames of hate darkened the world with smoke, and in that darkness, Shredder stole my daughter away from me. I thought she had perished that night, not knowing she would be raised by Shredder as his daughter."

Karai looked away at this.

"I had survived physically. Emotionally, I was destroyed. I wanted to escape, with Shredder believing me to be dead I escaped to New York, and I believe you know the rest."

Elsa's mouth was still covered, and tears formed in her eyes, almost ready to fall. For Anna, tears were already streaming down her face. Kristoff put his arm around her, but he had a look of anger, anger for the man who caused so much pain. Sven looked in shock as well. Olaf was confused, his child-like mind was unable to comprehend this.

"How can…" Elsa began, "I don't…. that's… that's horrible."

"How can anyone…." the teary Anna started, "...be so horrible… so… evil?"

"What kind of sick creature would do that to his brother!?" the angry Kristoff exclaimed.

"But it didn't stop there," Donnie began.

"What?" Elsa questioned.

"Yeah. 15 years later, when Shredder found out Splinter was alive, he came to New York looking for him," Raph started

"And pretty much brought the WHOLE Foot Clan with him!" Mikey stated.

"Not too long after Shredder found out about me and my brothers," Leo began, "Since we were students of Hamato Yoshi, we were put at the top of Shredder's hit list."

"But you guys were able to stop him, right?" Anna hoped.

"If only," Leo said, "When we first fought Shredder, we barely escaped with our lives."

That hit Elsa, Anna, and Kristoff hard.

"He almost killed you guys?!" Kristoff questioned, wondering how skilled warriors such as the ninja turtles, who took down dozens of mercenaries, Hans, the Duke of Weasel-town, and many Kraang droids, could almost die at the hands of one man.

"And it wasn't just us he was targeting," Donnie began to explain, "Anyone who was friends with us became targets too. He would either kidnap them and use them as bait to lure us, or try to kill them just to hurt us."

"He even sent me to try and kill them," Karai added.

The three looked at Karai with looks of shock and sympathy. Elsa now understood why she was shutting them out. She had lived a lie most of her life and never knew her mother.

"All my life I believed Shredder was my father, and Splinter was the one who killed my father," the kunoichi explained, "I was brought up as a deadly assassin, but then I met my real family and Leo opened my eyes to the truth."

Karai smiled at her brother, who smiled back.

Anna wiped the tears from her face, glad Karai was able to find her true home. Elsa and Kristoff were both happy for her as well, but they all still felt sorry for the poor girl.

"However, it would appear Shredder has his sights now on Arendelle," Splinter told them, getting serious.

"Those two mutants, Rahzar and Fishface, are two of his lieutenants." Raph began.

"'Two of'?" Kristoff said, "You mean he's got more?!"

"Yep, and they're all deadly mutants," Donnie answered.

"Not to mention, Shredder pretty much runs the New York criminal underworld," Mikey added.

"How in the world did he get mutants on his side?!" Anna questioned.

"Most of them started as humans. How'd he get them on his side? Shredder can be  very  persuasive," Karai told her.

"As for the 'mutant' part, Shredder got the stuff to make them mutants by allying himself with the Kraang," Leo said.

Elsa's eyes widened, "He works with those monsters? The same ones who wanted to take over your world?!"

"Yeah, the enemy of my enemy sort of thing," Leo answered, "The Kraang may have broad goals, but Shredder is far worse than they could ever be. Because he strikes so close to home."

"But why come to Arendelle?" Elsa questioned, "I may believe that he wants all of you, but that Rahzar character said Shredder wanted  me.  Why would we want me?"

The turtles were wondering the same thing, but an answer came to Leo's mind.

"Your powers."

"What?" The ice queen questioned.

"Shredder wants your powers," Leo said.

"You're right. That makes sense," Karai agreed, and Splinter nodded to that.

"My powers? Why would he want my powers?"

"Why wouldn't he?" Mikey questioned, "We saw what you could do with them, and you told us about them too."

"That's a good point," Donnie added, "Making an ice palace, bringing a being made of snow to life, and accidentally plunging a kingdom into an enteral winter…"

"Not to mention that 'frozen-heart' thing," Raph added as well, "And if a timid queen is capable of all that…"

"Just imagine what that kind of power could do in the hands of a murderous psychopath like Shredder," Leo finished.

The Turtles and Karai all shuttered at that thought, Splinter gained a look of concern.

"With that kind of power, he could freeze entire cities, create armies of ice monsters, construct massive fortresses in seconds, or maybe even plunge the entire world into a new ice age," Donnie speculated.

That made Elsa, Anna, and Kristof balk in shock, even Sven.

"He would go that far?" Kristof questioned.

"You have no idea how far he would go," Karai said.

"So… I'm his target," Elsa said simply, only for Anna to cling to her elder sister.

"No! I'm not letting someone like him get to my sister!"

"Something tells me he doesn't care what you think," Raph said.

"Arendelle is now in grave danger. Shredder's forces may fail  this time , but they will try again," Splinter said.

"Well, at least things can't get any worse."

As soon as Mikey said that, the door to the throne room burst open, and a distressed guard ran to the group.

"Your majesty!" the guard exclaimed as he ran up, "I have terrible news."

"It can't be any more terrible than what's going on now," Elsa stated.

"What's going on now…? Eh, never mind," the guard stumbled, "During the attack from those 'Kraang-creatures', there was an explosion near the dungeon and…."

"Don't stutter. Spit it out!" Karai exclaimed.

"Uh yes," the guard exhaled, "Hans has escaped."

Amidst the wide eyes of the heroes, Mikey was slapped in the back of the head by Raph.

"You just  had  to say it, didn't you?"

Arendelle Mountains, Kraang Cave

In the mountains near Arendelle, by the entrance of the cave where a small group of Kraang made a small base out of it, Hans stood waiting.

A few minutes later, Rahzar and Fishface had both walked up to the cave with looks of disappointment, Hans sighed in disappointment as well.

"No Elsa?" he asked.

"What do you think?" Fishface told him impatiently.

"I could have told you a full-frontal assault wouldn't work," the former prince of the Southern Isles said with a cocky smile.

"Watch it, Princey!" Rahzar exclaimed as he shoved Hans with his massive claws.

"I  did  try to warn you. It's not  my  fault you didn't listen," Hans stated, resulting in the two evil mutants growling at him.

Before something could start, a Kraang droid had walked up to the three.

"What is it?" Fishface asked.

"The one known as Shredder wishes to speak to the ones that are the three of you, whom he wishes to speak to," the Kraang droid answered.

"Shredder's asking for a report," Rahzar translated as he and Fishface walked into the cave, with Hans close behind him.

"He's not going to be happy," Fishface observed.

Once at the end of the cave, in the center of the alien machinery with five or six Kraang present, a hologram of Shredder appeared.

Rahzar and Fishface bowed down to their master. Hans followed suit as well. Even though it was just a hologram, being in Shredder's presence made Hans nervous.

" Well? " Shredder began.

"Master Shredder," the canine mutant began, "We attacked the castle and we're able to identify the queen."

" But? "

"But…." Fishface gulped, "We were unable to…"

He coughed, "...capture her."

The Shredder hologram narrowed its eyes, " You mean to tell me, that two of my most powerful and dangerous warriors, who each have bested many ninjitsu masters in battle, and have been gifted augmented abilities when mutated, we're unable to retrieve a SIMPLE CHILD!?"

"With all due respect, Master," Rahzar defended, "The Turtles and Splinter gave us a bit of trouble as well."

"Not to mention that brat Karai," Fishface added, resulting in Shredder glaring at him. Fishface realized what he just said and lowered his head even more.

" You were aided by many of my Foot combat drones, and yet you were still bested in battle?! This I will NOT tolerate."

"Those Foot bots we're all destroyed by the queen," the fish mutant defended, "We may not have seen it, but we sent a large majority of them to her. She was able to fend them off."

"Without any real combat training!" Rahzar added, "She is going to be a tough one, master."

" You WILL bring her to me! I will not hear any more excuses!"  

"If I may, Master Shredder," Hans butted in, "A frontal assault won't work with Elsa. Take it from me, I tried it before, and it failed."

He recalled when he and many were sent to retrieve Elsa from her Ice Palace during the 'Frozen Kingdom' crisis, but weren't so lucky, "And with the Turtles guarding her, maybe a  different  approach is in order."

" What approach would you recommend then?"

"Something more on the stealth side. Someone who can easily sneak into the castle, get to the queen, and bring her to you," Hans suggested.

" Such a tactic could be useful. Bradford, you said this 'Elsa' was able to destroy a majority of the forces that accompanied you and Xever?"  

"Yes, Master," Rahzar confirmed.

" It only proves that such a power can be useful. Hans, y ou have done well to bring this queen to my attention. Her power will be adequate for the destruction of the Turtles and the rat."

"I aim to please," Hans said, smirking, which was noted by both Rahzar and Fishface, "When Elsa is in your possession, what do you plan to do with Arendelle? With they're queen kidnapped, they're bound to be in a state of panic and disarray."

"That kingdom is of no concern to me."  

"Oh? Well if I may be so bold to request, when you have Elsa's magnificent powers, and her kingdom is no longer hers, perhaps, I could rule? Eh, with your permission of course," Hans finished.

Shredder thought about this for a moment.

" I will consider it. Success is to be rewarded, as failure is to be punished ,"  he finished, glaring at Rahzar and Fishface, " You will all await further instruction."  

The hologram cut off.

The three then rose from the bowing positions.

Fishface coughed, "Ugh. Kiss up. Ugh."

"I'm sorry is that supposed to mean something?" Hans pondered.

"You think you can buy Master Shredder's trust?" Fishface questioned, "He'll see through any façade you have in store."

"I have no intention of deceiving him," Hans defended.

"You may say that now," Rahzar started, "But who knows what can happen later? So you had better watch your back pretty boy, because if you so much as give a white lie, I'll be chewing on it."

"I'll keep that in mind," Hans said.

New York, Foot lair

Shredder had sat down on his throne, just finished giving his orders to his forces in Arendelle. Tiger Claw was present as well, having heard the whole thing.

"Master," Tiger Claw began, "You do not honestly believe that Hans could be a part of the Foot?"

"Are you questioning me Tiger Claw?" Shredder said in an impatient tone.

"It is not you that I question, my Lord. It is that prince," Tiger Claw stated, "He may say he is loyal to us now, but what is to stop him from trying to usurp you later? I do not trust him."

"Do you take me for a fool? I am aware Hans cannot be trusted. He may have spoken the truth in revealing the ice queen to me, but I know his kind. He'll say what he wants us to hear and will move in the shadows, biding his time with tricks and deception, but he will not fool me. Should he slip up, I will end his miserable life."

Tiger Claw smiled and bowed at that, "Forgive me for doubting you, my lord."

"Now back to the matter at hand. With the Turtles and Splinter protecting the queen, a simple attack will amount to nothing, so now we try a different approach."

"What do you have in mind, Master?"

Stockman's Lab

In the basement, deep beneath Shredder's lair was the massive lab of Doctor Baxter Stockman, Shredder's scientist.

The lab was huge, with a massive orb container of Mutagen at the top, and along the walls were habitats of various mutants that were found off the streets of New York, or created through Stockman's experiments.

As for Stockman himself, the mutant fly was now at his desk working on a chemical experiment.

"Whatever you want, I can create it," Stockman-fly said to himself. Stockman-fly was about to add a drop of a chemical to another one and was proceeding slowly, "Zzzzome mutagen, a few chemicalzzz...I muzzzt be careful. Even the zzzligthezzzt drop can…."

"Stockman!"

The sound of Shredder's voice made the fly-scientist-mutant stumble and accidentally pour the whole contents into the chemical, resulting in it boiling rapidly.

"Uh oh," Stockman said.

*BOOM!*

Shredder stood unaffected and saw the soot-covered Stockman proceed to him.

"Uh… I meant to do that," Stockman-fly buzzed.

"Spare me your prattling, Stockman," Shredder interrupted, "Have you finished the controls for your 'pets'?"

"Azzz a matter of fact, yezzz, Mazzter," Stockman buzzed again before flying down to one of his habitats.

This one was dark inside, and one could only just barely make out quick movement.

"They are ready to go, and ready for battle, Mazzzter Shredder," Stockman-fly said to Shredder, observing the creatures in the habitat.

"Excellent," Shredder responded, "I have an assignment for you and your pets Stockman."

From inside the habitat, a pair of green-glowing eyes are shown, before a screeching sound is heard.

Chapter Text

Arendelle Dungeon

As if things weren't bad enough for our heroes, Shredder, the most evil ninja master to walk the earth has set his sights on Arendelle, specifically Elsa. In addition, Hans has escaped. True, that Shredder poses a far more significant threat than Hans could ever hope to be, but he's still dangerous.

So now, the heroes are in the dungeon, trying to get information out of Hans' recent accomplices.

"Why would I tell anything to you, monsters?" the Duke of Weselton, or rather, former duke , was questioned in one of the interrogation rooms.

The ones interrogating him were Queen Elsa, accompanied by Raph and Mikey, with two guards present as well.

"Because he is a dangerous criminal," Elsa answered.

"The only 'dangerous' thing here is you!" the duke replied hastily, earning an eye-roll from Raph.

"Dude, don't you have, you know, some kind of civic duty or something?" Mikey asked.

"What does a demon like you know about being 'civic'?"

Raph had just about had enough of this old twig. It was a wonder why he hadn't blown up so far, "If you're done with that, start saying something useful. You know, like stuff about Hans?"

"What will you give me for it?"

"'Give you for it'?" Raph questioned, with an eyelid twitching.

The former duke glared at the ice queen, "Well, it's just that Arendelle, one of the world's most wealthiest kingdoms is asking someone from Weselton for aid in tracking a criminal. However, all business relations between our countries have ceased. So, if you want information, you are going to have to make it worthwhile."

Raph replied with a fake smile, " Oh I'll make it worthwhile. I won't take your head and SMASH IT AGAINST THE….!"

"Okay! Okay, thank you, Raphael. I will take over," Elsa interrupted, putting her hand on Raph's shoulder, causing him to look away pissed.

The two guards made it as far from the red-clad turtle as possible. Mikey just looked unsurprised.

"What is it you want?" Elsa asked.

"Hmmm. Maybe five thousand pounds of gold just for starters," the duke proposed.

"That's not an option. I can't just give that much money away."

"I've got plenty of old Canadian quarters that fell in the drain a while back."

The duke crossed his arms and turned his back on them, "If you're unwilling to compromise with me, then I won't tell you anything."

"That's it!" Raph exclaimed.

He then grabbed the d uke and slammed him against the wall.

"Raph? What are you doing?!" Elsa questioned.

The guards were about to move, but Mikey stopped them from doing anything that would anger Raph even further.

"You want a compromise? Here's one," Raph offered, a fiery rage surrounding him, "You tell us everything you know about Hans right now or so help me. I will bend your tiny body like a pretzel, toss you into the harbor, and watch you sink into the pit you crawled out of!"

At that moment, the d uke lost all his leverage  and his last pair of clean underwear, "I DON'T KNOW ANYTHING! He came to me! He didn't say anything to me! That's all I know! I SWEAR!"

Raph looked into his eyes and could tell this insidious pest was telling the truth and let him fall to the ground.

"Does he always interrogate like this?" Elsa asked Mikey.

"Sister, you have no idea," Mikey replied.

Meanwhile, in another interrogation room, the only other person who had dealings with Hans, Dregg of the Night Blade, was being questioned by Leonardo, Karai, and Princess Anna. Two other guards were present as well.

"What do you want from me?" Dregg asked.

"Anything about Hans," Leo answered.

"Why would I tell you that?"

"So we can find him , why else?" Anna answered.

"Sorry, it's our code , we never reveal anything about our clients in the event of a capture," Dregg explained, but took a small look at the princess, then to Karai, and gave a smug grin, "Heh, but then again, if you two young ladies could find some way to persuade me, I might be more cooperative."

*SLASH!*

In less than a second, Dregg's long black beard completely fell to the ground, leaving only stubbles. The wide-eyed leader of the Night Blade looked to Karai with an unsheathed blade.

"Is that persuasive enough for you?" Karai asked, catching his hint and not liking it.

The mercenary sweated a bit. Who would have thought that this girl would be the first one to send a chill down his spine? Leo wasn't surprised at Dregg being to tremble a bit, given who raised her.

"I don't know anything, okay?" Dregg began to explain , "All he said was 'kill the queen and I'll pay you '. That's it. He didn't give the specifics."

Leo, Karai, and Anna all looked at each other disappointingly.

In the hallways between the cells stood Donnie, Kristoff, and Splinter waiting for results. Two metal-squeaking sounds were heard. They all looked to the right and saw two of the doors open at the same time. Out of one exited Raph, Elsa, and Mikey; Anna, Leo, and Karai came out the other.

"So?" Donnie began.

"Anything?" Kristoff finished.

"No, nothing useful," Elsa replied.

"Same thing on our end," Leo added as well.

"I gotta give him credit , this 'Hans' guy knows how to cover his tracks," Karai said.

"Oh , believe me . He's an expert at that kind of thing," Anna replied, with a hint of contempt in her voice.

"So now what?" Mikey asked.

"We will have to worry about this 'Hans' person later," Splinter began, "Right now, we must prepare for Shredder, and when and how he will strike next."

"Is Shredder that much worse than Hans?" Elsa questioned.

"We just told you everything about him," Raph reminded, "Not to mention he's got loads of mutants on his side."

"And on top of that, he's a ninjutsu grandmaster with no sense of remorse or mercy," Donnie added.

"Yeah, bros. We're in real trouble," Mikey said

Elsa was looking even more nervous than she ever did in her youth when she was struggling to control her powers. She couldn't explain it but … it was like that feeling she got when she first encountered the Turtles, only the complete opposite. While she felt safe and happy with them, like they were her family, simply hearing the name 'Shredder' made her more nervous and frightened than anything; it was the first time she, in forever, was scared  of   someone, rather than someone.

Foot/Kraang Cave base, Arendelle Mountains

Rahzar, Fishface, and Hans all waited in the cave with the few Kraang droids at the stations waiting for anything from Shredder.

"How much longer must we wait?" Fishface questioned.

"As long as it takes," Rahzar replied.

"Speak for yourself , I'm not a patient man."

"Patient fish, you mean," Hans corrected, earning a glare from said fishman.

"You're not helping," Rahzar told the former prince.

"My apologies, I was trying to lighten the mood," Hans explained, "I feel as though we've started on the wrong foot, and I was wondering if we could start over?"

"I think we already made it clear that 'sweetening' your way in is not gonna help you, amigo," Fishface reminded

"I'm just trying to establish some friendly ground with my comrades. If we're going to be working together, I think it would be most efficient if we got along, wouldn't you agree?"

Before either Rahzar or Fishface could reply, a Kraang droid came up to them.

"That which is known as the portal that is meant for traveling between the dimensions that are the dimensions of Earth and this dimension is opening."

"What did he say?" Hans asked.

"He said the portal's opening," Rahzar translated.

"Ah," Hans replied simply .

With that, the pink triangular portal expanded and opened. Rahzar, Hans, and Fishface all straightened up, wondering what was coming through. Their answer came in the form of a humanoid fly.

"What. Is. That?" the former prince questioned.

"Stinkman? Master Shredder sent you?" Rahzar asked.

"Yezz, he did. You got a problem with that, Rahzzzar?" Stockman-Fly responded.

"Uh, who is this?" Hans asked Xever.

"Baxter Stockman," Fishface replied, "An inventor in Master Shredder's employ."

"Well… Baxter, it's nice to meet you," Hans greeted extending his hand.

Stockman-fly merely buzzed before accidentally secreting slime from his mouth onto Hans' hand, much to the prince's disgust. Fishface and Rahzar both smiled at that.

Rahzar noticed the metal backpack that Stockman was carrying and caught a familiar scent with it.

"Stinkman," he began impatiently, "That better not be mutagen in there."

"It mozzzt zzertainly izzz mutagen," the bug scientist replied, taking out a canister of the glowing green substance, which Hans looked at with interest, "You never know when zzzomething like thizz may come in handy."

He put back the vial.

"Getting back to the matter at hand…" Fishface started to say , "I'm sure Master Shredder has told you what you're supposed to be doing here."

Stockman-fly nodded.

"Then how can you hope to capture the ice queen, when Bradford and I, with over thirty Foot-bots, failed to do the same task?" the humanoid fish questioned.

"You honezzztly don't ezzpect me to come here without a plan do you?" Stockman-fly answered, "My petzzz and I will certainly get the job done."

"'Pets'?" Hans, Bradford, and Xever questioned at the same time.

All four turned to the portal just to see what was coming out, making the prince, dog-mutant, and fish-mutant look with wide eyes .

"That might do it," Rahzar said simply .

Night had fallen upon Arendelle. Most citizens have now gone home and all we're asleep, minus the guards. It appeared that every guard was now outside the castle, guarding every possible entry. They were told that their Queen had been targeted for kidnapping and that monsters would come for her, so now they stood vigil, at every corner, they stood waiting for any 'monster' that would dare try to abduct their beloved queen.

There were two guards outside by the waterfront; this was the same place Elsa ran outside after accidentally revealing her abilities.

"So… what are we expecting exactly?" one guard asked.

"Not sure," the second guard responded, "Those Turtles said be prepared for anything."

"Well, given that we've recently encountered those brain creatures in metal bodies, along with that man-dog and giant fish, I think it's safe to assume it's another thing like that."

"Yeah. Probably."

After about five minutes of uncomfortable silence ...

"Heh. Can you believe they're turtles?"

"I know. Crazy right? Here I thought the queen's ice magic and that little snowman was crazy enough but …"

Something caught his eye, "What was that?"

"What was what?"

"I thought I saw something move in the water."

Both guards chose to take steps further on the rocks , closer to the water, they saw nothing. However, there was a splashing noise to the right, causing them to turn right and point their spears, but all they saw were ripples in the water.

"Maybe it was just some fish?" one of them assumed.

"Hopefully," the other said,

Suddenly, an inhuman noise sounded behind them, causing them both to turn around slightly. Once they're eyes set upon what they saw, they regretted coming outside.

Meanwhile, in the castle hallways, Anna found herself pacing back and forth nervously. This was noticed by Kristoff.

"What are you so worked up about?" he asked.

" Oh nothing much," Anna replied simply, "It's just that a murderous maniac who's ten times worse than Hans and wants to kill my friends is trying to kidnap my sister! But other than that, I'm fine."

"Look I know you're worried, but we've got people who've fought this guy before."

"I know, and I also know that they're pretty scared of him too. Given that they took down over a dozen professional assassins and are scared of just one guy, I can't even begin to think of how bad that sounds."

Kristoff put his hand on her shoulder, "You're right. This Shredder guy is a huge problem, and I'm a bit nervous myself . But I also know if all of us stick together, I'm sure we'll all be fine."

Anna smiled at this, and the two hugged.

"You always know what to say," Anna told him.

They looked into each other's eyes and kissed.

"Aw, young love."

A voice spoke, causing the two to look further down the hall to the source of the voice, Splinter.

They quickly broke off, both blushing immensely, "Uh… Master Splinter." Anna greeted, "Hi… I … how long have you been there?"

Splinter smiled before he spoke, "I only just arrived, but I also couldn't help but overhear you voice your concerns."

Anna looked down a bit , but Splinter put his hand on her shoulder and looked at her like a father would his child, "You have a strong and caring heart, and wish to help your sister and your friends. This is admirable, but you needn't worry. I promise that I will not allow Shredder to get his hands upon Elsa."

Anna smiled at the humanoid rat, "Thank you."

"You are wise, you know that? I can see why your sons look up to you," Kristoff said to Splinter, who smiled back at him. He liked the master before him. He reminded him of Grand Pabbie.

All thoughts were brushed aside when a scream was heard , and all had looks of great surprise .

"What was that?!" Anna exclaimed.

"This way," Splinter instructed as he ran off, Anna and Kristoff not too far behind him.

Due to his heightened senses from his ninja training, Splinter was able to navigate to the source of the scream, and having the ears of a rat didn't hurt either.

The three made it to the waterfront, where they found the two brutally injured guards sprawled out on the rocks. Anna ran to one of the guards, only to find that one unconscious. Splinter and Kristoff came to the other one who was only barely conscious.

"Are you alright? What happened?" Kristoff asked,

"M… m… monsters…. inside…. Hel p… Queen Elsa," he fell limp.

Anna came to him just as he did.

"Is he…?" she nervously asked, fearing the worst.

Splinter put his fingers to the guard's neck feeling for a pulse.

"No. He is alive."

They both breathed relief.

Soon, they heard footsteps coming outside. They turned to see the Turtles, ice queen, and kunoichi.

"Father?" Karai asked.

"What's going on?" Donnie asked.

"Woah, what happened?" Raph asked as well, noticing the guards.

"Something's inside the castle," Kristoff replied.

All eyes went wide, especially Elsa.

"What?" Leo questioned.

"A mutant?" Mikey thought.

"Possibly, but we must hunt it down before it can cause harm," Splinter instructed.

"We'd be too big of a target if we all searched in one group , Let's split up," Karai proposed.

"Good idea. Mikey and Karai, with Elsa; Splinter and Raph, with Kristoff; Donnie and me, with Anna," Leo instructed, "Let's go. Be on your guard, everyone."

The door to the dining hall was slowly opened .

Donnie peered inside before slowly opening the door all the way. Leo rolled in quietly. Both turtles had weapons at the ready. Anna sneaked in along the wall as quietly as she could.

"So wh…." she began to speak only for Donnie to quickly cover her mouth .

"Shhh," both turtles quietly shushed.

"It could have super hearing," Donnie whispered.

"Full ninja mode," Leo whispered as well as Donnie took his hand off Anna's mouth.

"Sorry," she whispered, "What are we looking for?"

"I think we'll know when we see it," the purpled-clad turtle said.

They began their silent search of the dining hall for who-knows-what.

Within the darkened room of the library, Splinter was the first to enter, followed by Raph and Kristoff. The humanoid rat looked in between the bookshelves , Raph rolled underneath all the tables quietly, sais at the ready. Kristoff, slowly opened the doors to the small storage rooms, peered inside, and saw nothing.

Raph tried his best to keep his cool, but he was getting a strong unsettling feeling that was strangely familiar to him. He thought he had gone through something like this before, but when?

Mikey slowly opened the door to Elsa's room, a nunchuck in his left hand. On his right, he threw in a pebble, hoping the sound would draw out what could be inside, but nothing.

Elsa followed into Anna's room , she threw in a small ice ball as Mikey did, and nothing followed.

Karai did the same with a rock in one of the guest rooms, only to get the same result.

"How will we know if we find it?" Elsa whispered.

"With our luck, it will find us," Karai whispered back.

"Ladies, I am getting a strong sense of familiarity here," Mikey whispered, getting a little nervous, "I feel like I went through this before."

"I'm guessing it didn't end well," Karai assumed.

Before Mikey could respond, a faint inhuman noise was heard . It sounded like a faint hiss. Mikey's eyes slowly widened.

"I think I heard that sound before," the youngest turtle recalled, getting an idea of what may be inside, just hoping that he was wrong.

He and Karai turned to the queen who was looking up to the ceiling in a bad kind of awe.

"Elsa?" Karai asked.

"What…. is… that?" she frightenedly and slowly pointed to the ceiling, where some green drool slowly fell , both looked up at what she saw.

Karai's expression was that of worry, whereas Mikey's was of total terror.

"No..." Mikey began, "Not the… Not th e… Not the…."

But it was, the one mutant he feared even more than Rahzar.

"…SQUIRRELANOIDS!"

Said Squirrelanoid dropped down in front of them and snarled.

Karai drew her blade, and Elsa readied her powers, though the latter was more scared than the former.

"What is that?!" Elsa exclaimed.

"Not sure exactly, but I don't think it's friendly."

But before either of them could attack, Mikey picked up both the surprised girls over both his shoulders and ran down the hall in complete terror, at near superhuman speed.

"RUN DUDETTES! RUN!" he screamed, with the Squirrelanoid chasing after them.

Mikey's scream was heard by both parties throughout the castle, and they all ran out to see what the heck was going on.

"RUN! RUN FASTER!" Mikey yelled again as he kept running through the castle halls.

"It's kinda hard to do with you carrying us!" Karai angrily yelled.

Mikey had just run outside to the courtyard, where Karai was able to give a kick to Mikey's leg, causing him to trip and drop both girls , they all got up.

"You're seriously running!? What kind of ninja runs from a fight?!" Karai questioned, only for Mikey to grab her by the shoulders.

"You don't know how dangerous these mutants are!" Mikey exclaimed as he shook his sister, "They'll crack our shells like nuts! Game over man ! Game over!"

*SLAP!*

"Get a grip will you!" Karai yelled back.

"Is now really the time to fight amongst ourselves?!" Elsa exclaimed as she separated the two.

"Guys!" they hear Raph say.

They all turned to see him, Leo, and Donnie run out, with Splinter right behind them, and Anna and Kristoff closer to the main door.

"What the hell are you screaming at!?" the red-clad turtle yelled.

Before Mikey could answer, Elsa turned to her younger sister and saw something she didn't like.

"Anna, LOOK OUT!"

Anna could only look in question at her sister before a pair of hands grabbed her and pulled her up. She screamed as she was pulled to the top of the doorway and came face to face with a Squirrelanoid. It snarled at her, and she screamed .

"ANNA!" Kristoff yelled, only for something fast to woosh past him.

Before Anna knew it, she was pulled away from the monster, and could only look up at Splinter carrying her as he landed away from the monster .

Before anyone could do anything else, something had pounced on Kristoff. As he hit the ground, he looked up to yet another Squirrelanoid trying to bite at his face with a second mouth. He tried to hold it back, only for Raph to tackle the thing and throw it away.

All the heroes quickly gathered in a circle, and the three Squirrelanoids circled them.

"Crud! Not these things again!" Leo exclaimed.

"What are these things!?" Anna exclaimed as well.

"They're squirrels," Donnie answered.

"SQUIRRELS!?" Elsa, Anna, and Kristoff all shouted.

"But… they're usually so small," Kristoff winced a bit .

"And… not deadly," Anna recalled.

"Yeah, until they got hit with Mutagen," Leo said.

"Yezzz."

A new voice spoke from the air, causing them to look up.

"The miraclezzz of Mutagen."

" Wait is that… a… man-fly?" Anna questioned.

"Dorxter Blockhead?!" Raph exclaimed.

"Itzzz Baxter, ZZtockman! I'm your arch-nemezzzizz!"

"Not really. I can think of five nemeses way angrier than him ," Mikey told Elsa.

"Uh, who is that?" Kristoff asked.

"Baxter Stockman," Karai answered, "Evil inventor, works for Shredder."

The three Squirrelanoids quickly gathered around Stockman-fly as he descended and hovered six feet off the ground, ten feet from the heroes.

"You are controlling these mutants," Splinter deduced.

"Yezzz I am," Stockman-fly replied.

He showed a little silver remote in his right hand/pincer and it revealed silver collars around the necks of each of these mutants.

"You like my new petzzz, Turtlezzz? They make ezzzelent hunt-dogs."

They all readied themselves for battle.

"Now my petzzz. Get the queen!"

With that, the Squirrelanoids snarled and leaped to the heroes.

Chapter Text

Arendelle Courtyard

Leo was sent flying back, rolling along the ground. He quickly recovered and took up his twin blades. He looked up to a screeching sound and jumped out of the way of a pouncing Squirrelanoid. He leaped at it swinging his blades. The mutant squirrel merely ducked and smacked him back with its tail.

The creature would have pounced back at its prey if it didn't feel someone jump onto it. It was Donnie, bouncing off the pinned Squirrelanoid and taking a fighting stance next to his brother.

"Is it just me, or are these things stronger than last time?" Leo questioned.

"Must have been Stockman's experiments, probably juiced them with drug enhancements," Donnie guessed.

"Well, whatever the case, they're after Elsa, and we gotta take 'em down."

The Squirrelanoid recovered and snarled at the two turtles as they charged in, weapons blazing.

Raph and Karai are on top of the roof over the gate to the bridge leading to the town. They had their respective blades drawn as the second Squirrelanoid slowly approached them.

"What are these things again?" Karai asked.

"Mutant squirrels," Raph answered, "You weren't there. Very fast and deadly."

"And Mikey's afraid of them?"

"Oh yeah, big time."

"Kinda like you and cockroaches?"

"Not the time, Karai."

The Squirrelanoid pounced to the two ninjas who jumped out of the way. Raph ran in first, swinging his sais at it relentlessly, it was nimble enough to avoid all the attacks. It quickly noticed Karai leaping down to it, blade high and ready, and it jumped back to a higher point on the roof next to a pole.

This was anticipated as Raph threw his sai to the pole as it landed and it stuck the mutant's hand to the pole, trapping it. It tried to pull its hand free, but it was stuck.

Before Raph or Karai could even think to move all three heard...

"Booyakasha!"

The Squirrelanoid looked behind to see Mikey charging and slamming his nunchucks at the creature repeatedly. He jumped back behind Karai and Raph.

"And where were you?" Karai questioned.

"I was waiting for you guys to trap it, so I can flank it," Mikey said.

"Or you were just afraid and hiding," Raph corrected.

"You try fighting something that wants to suck out your brain!" the orange-clad turtle challenged, taking some offense to Raph's comment.

"We just did, and you might get your chance now," Karai pointed up to the Squirrelanoid that just wretched its hand free and snarled down at the three warriors.

Mikey quickly hid behind his older brother and sister.

"Uh, you guys corner and I'll flank it again," he gave a light laugh, fear evident.

Both hot-tempered ninjas eye-rolled at Mikey's statement, just before the mutant squirrel jumped down towards them.

The third Squirrelanoid was thrown into a fountain. It quickly rose and glared at its opponent. Master Splinter kept his cool as he glared back at the creature as it slowly got out of the fountain and began to circle with Splinter slowly. The two did not give in as they continued to circle and stare each other down.

The Squirrelanoid made the first move. It jumped to Splinter, who twirled his cane and used its momentum to throw the Squirrelanoid over him and onto the ground. It rolled along the ground before getting back up on its fours and continuing to snarl in an attempt to instill fear in its so-called prey.

Splinter did not have even the slightest fear of this creature, evident as he motioned for the creature to come at him with his hand.

Elsa was running and rolling to avoid the slimy balls spat out by Stockman as he continued to fly over her like a bomber. She responded by sending out bolts of her ice magic from her hands straight at Stockman-fly, who merely flew away from them.

Anna came to her elder sister and helped her to her feet, while Kristoff took a protective stance in front of the queen and princess.

"First, we meet mutant turtles, then brain-squid creatures, then we met the turtles' master who happened to be a rat, then a giant fish with metal legs and a bony dog; now we got a giant bug!? What's next a pig and a rhino?" Kristoff questioned.

"What do you want with me?" Elsa demanded the humanoid fly.

"Mazzzter Shredder hazzz great planzz for you. You're majezzzty."

"Tell Shredder he can't have my sister!" Anna shouted defiantly at Stockman.

"You don't have a choizze in the matter," Stockman-fly commented as he flew down, making a beeline for Elsa.

However, Anna pushed Elsa out of the way only for Stockman-fly to fly and crash into her. The two rolled on the ground with Stockman pinning her to the ground with his hands.

"You look deliciouzzzz ," he said as drooled some slime on her.

"Ew. You are seriously disgusting," Anna commented.

Kristoff then grabbed Stockman-fly and yanked him off of her, before turning the humanoid fly around and punching him in the face, knocking him back, "Get off of her!"

"Hey! Watch the mandiblezzz , you jerk!" Stockman-fly exclaimed before taking to the skies again.

Elsa helped Anna back to her feet as she wiped the slime off of her face. "Are you alright?"

"Aside from being grossed out, I'm fine," the brunette answered, "Ew."

Arendelle dungeons

The former Duke of Weselton and Dregg each sat in a separate cell across from each other. Dregg's cell had a window near the ceiling letting in some light, not much considering it was night.

"Hmp. I wonder where Hans is?" Dregg commented, just for the sake of conversation.

"I don't care for that man," the duke responded, "He helped to put us in here."

"That's the first time I've heard you blame someone else other than the ice queen."

"Oh yes! She is responsible for everything else that has happened to me! She and those demon turtles. The one in red threatened me, me of all people!"

Dregg sighed, not eager to hear the duke rant on Elsa being a monster and the 'demonic' Turtles, "And here we go again. I should have kept my mouth shut."

Castle hallways

Olaf was walking next to Sven as the two continued to wander the hallways.

"I wonder where everyone is," Olaf wondered out loud.

Sven gave a curious look as well, wondering the same thing.

"You think they might be playing hide-and-seek?" Olaf asked Sven who raised an eyebrow.

"I mean it's been so quiet. Why else would it be quiet? You think they can all use a hug?"

Sven rolled his eyes. This was the snowman's solution for everything. But its face became one of curiosity as it picked up a scent. It then dove to the ground and began to sniff the ground like a dog.

"You found something, Sven?" Olaf asked.

Sven then ran down the halls at high speeds, leaving the snowman all alone.

"Oh! Are you playing hide-and-seek too?" Olaf called out, "I'll take that as a yes."

He then covered his eyes and began to count, "One, two, three…"

Sven ran down the hallways, turning every corner, running down the stairs, and to the main gate. He burst through the doors leading to the courtyard and saw what was going on . All his friends were battling strange creatures, and for some reason, they smelled a lot like squirrels.

The reindeer looked to one was and saw Leo and Donnie both battling against one of these creatures. They were both on the defensive as the creature kept forcing them back, Leo using his blade to block the creature's strikes with its claws, with Donnie trying to bash it with his bo-staff, only for it to jump to the wall and pounce to the two turtles who leaped back.

He looked up to the roof near the gate leading to town. He saw Mikey cowering behind another part of the roof while Raph and Karai tried to fight another creature. Raph tried to strike with his sai, but the creature knocked him back with his tail it then leaped and clawed at Karai, who was forced to jump back.

He looked to the left and saw Elsa trying to blast ice toward what looked like a giant fly with clothes. When it got close to the ground, Kristoff would try to swing with his hatchets, but it merely flew high at it. Anna looked like she wanted to help, but Elsa gave a hand motioning for her to stay back.

He thought to help his rider and his friends, but he heard a sound. He looked towards the fountain and was shocked at what he saw.

Master Splinter found himself pinned to the base of the fountain. The Squirrelanoid was on top of him, trying to bite with its second mouth. The only thing keeping it back was Splinter's cane, pressed against the creature's neck. Splinter struggled to hold the monster back and it looked as though he was about to give. However, fortune came his way as Sven came running to Splinter and rammed into the Squirrelanoid; knocking it off.

The mutant squirrel got back up and snarled at Sven, who growled back at it, ready to fight. Splinter recovered and then patted the reindeer on his head in gratitude.

"Thank you, my friend."

Sven gave a smile to Splinter before turning to stare down with the mutant. Curiously, the Squirrelanoid gave a few whiffs and looked to the pack that was on Sven's side.

The humanoid rat was curious about this as well. He looked at the pack, wondering what made this creature so curious. He slowly reached into the pack and began to feel something, quite a few somethings inside. He took one of them out; it was a carrot. Splinter remembered Sven loved carrots; Kristoff constantly fed them to him.

Splinter slowly waved the carrot up and down, the mutant squirrel's eyes following the carrot with its full attention to the vegetable. He then also remembered that Squirrelanoids were attracted to the scent of food. An idea formed in his head.

He looked to the reindeer, "Sven, perhaps you would be willing to help me."

Sven then looked to Splinter with a curious look on his face.

Raph and Karai were both swept off the roof by the tail of the Squirrelanoid they were fighting. Mikey jumped down and caught both of them. He threw his nunchuck out as the chain extended and caught the edge of the roof allowing the three to descend to the ground slowly.

They got to the ground and recovered just as Leo and Donnie were forced back.

The five ninjas then got together back-to-back-to-back-to-back-to-back as the two Squirrelanoids began to circle them.

"Well guys, it's been nice knowing ya," Mikey squeaked.

"I am NOT about to be out-matched by over-sized squirrels!" Karai exclaimed in frustration.

"Giant mutant squirrels that reproduce inside stomachs and…" Donnie began.

"Not now, Donnie !" Leo, Raph, Karai, and Mikey all yelled at the same time.

"It lookzzz like your guardianzzz are about to be zzzqewered your majezztiezz ," Stockman-fly mocked as he pointed.

Elsa, Anna, and Kristoff looked to where he was pointing and saw their friends circled by two Squirrelanoids.

"No! I can't…" Anna began to run to them to help.

Kristoff and Elsa would have stopped her if some acidic spit hadn't landed in front of her, blocking her path.

"I don't think zzzo ," Stockman-fly protested as he flew in front of them, not about to let them pass.

Before the Squirrelanoids could even think about pouncing onto our heroes, two objects were thrown at them. Both of them caught each object with their second mouths and pulled them in eating them. They were carrots.

Each of the five ninjas looked with curiosity, as did Elsa, Anna, Kristoff, and even Stockman.

They all heard a whistling sound and all of them, Squirrelanoids included, looked to Splinter, with Sven, holding a sack full of carrots and making them visible to the Squirrelanoids.

"Are you beasts hungry?" Splinter questioned as he took out a carrot and handed it to Sven, who munched on it.

Splinter also tossed one to the Squirrelanoid he was previously fighting.

"What izzz he doing?" Stockman-fly questioned.

"Sensei?" Leo and Raph both asked.

"Father?" Karai asked.

"Sven?" Anna asked.

"Are those Sven's carrots?" Kristoff questioned.

"If you are hungry, then come and get me," Splinter challenged as he quickly got onto Sven and rode him into the castle.

The Squirrelanoids all snarled as they eagerly leaped past their enemies and ran after Splinter and Sven into the castle, hungry for food.

"What!? NO! Get back here!" Stockman-fly exclaimed.

"Looks like Sensei has a plan," Donnie noted.

"Uh, should we help him?" Anna questioned.

"I think he can handle it," Elsa assured, trusting the rat master.

"YOU UNGRATEFUL MONGRELZZZ!" Stockman-fly yelled into the castle, "GET BACK HERE AND ZZZERVE YOUR MAZZZTER !"

"Ahem."

The fly heard as he slowly turned around and looked down to see Leo, Raph, Elsa, Donnie, Kristoff, Mikey, Anna, and Karai all with their respective weapons or powers (minus Anna not having either), each eager to put some hurt on this fly.

"Well, thizzz izzz awkard."

"Not really," Mikey replied.

"Stockman," the blue-clad Turtle declared, pointing his blade to him, "Leave now, and you might make it easier on yourself."

"But considering it's Shredder you'd have to report this to, I wouldn't make any promises," Karai added.

"I don't think zzzo !" Stockman-fly then drew a strange device from his backpack.

"What is that?" Kristoff asked.

"He's got a grenade!" Donnie yelled.

"Zzzurender, or thizz cazztle will be blown zzzky high!" Stockman exclaimed before a white bolt came from Elsa and struck the grenade sending it flying over the castle.

"That is not going to happen," Elsa declared.

"NO! Not my only grenade!"

"Really?" Raph questioned, "You come into battle with only one grenade?"

"He's not your smartest enemy is he?" Anna asked Mikey.

"No, not really."

Arendelle Dungeon

The Duke of Weselton continued his rant. To pass the time, Dregg began to sort through various vials that he snuck in. Each vial had the different kinds of venom of various animals; snakes, spiders, even some fish, and many others. Dregg was able to cleverly hide them thanks to his training as a smuggler and assassin.

He had a plan. He would 'kindly' offer a guard some water laced with the venom. After the guard falls ill, he steals his keys and leaves this good-for-nothing kingdom.

Dregg's smile vanished when he heard clanging from his cell window, he turned to it.

"Just who do they think they are?!" the duke continued to rant, "Locking me in here like a worthless rat! All I wanted was Arendelle's seemingly endless riches and exploit them, was that too much to ask!?"

He then noticed Dregg approaching the window, "What are you doing?"

"Some strange object is at my window," Dregg answered as he came to the window to look at the mysterious object which had a blinking red light.

It was Stockman's grenade.

*BOOM!*

A large explosion occurred and the Duke was forced to the back wall from the shockwave. The dust filled his cell, causing him to cough and hack as he tried to wave away the dust to clear his vision. As the dust cleared he noticed somethin g…

The bars of his cell had been blown off.

The Duke made a few steps out into the dungeon hallway. His curiosity allowed him to look into Dregg's cell where he saw Dregg sprawled out on the floor, clearly dead.

The Duke sighed, "Serves you right, you savage."

He then straightened his ragged clothes and prepared to walk out, "Now then, it's time to take my…"

However, the Duke tripped over a broken cell bar and fell to the ground. He heard glass shatter and felt a sharp pain in his right palm. He screamed in pain. He got up to look at his right palm and found shards of glass embedded into it, along with blood seeping out.

He would have cursed if his vision hadn't gotten blurry.

"What? What is this?"

He began to feel more and more dizzy.

"It's not just the queen. This whole kingdom must be cursed!"

He began to quickly and wobbly try to escape the dungeon.

"I must leave this place before it's too late!"

As the duke continued to walk out he failed to notice part of one of Dregg's vials of venom that he had on hand. It had the black symbol of a scorpion on it.

Castle hallways .

"97… 98… 99… 100! Ready or not, here I come!"

Olaf uncovered his eyes and began to search for his friends, his childish mind assuming they were playing hide-and-seek.

"I'm gonna find you guys!" he said as he looked down the hallway.

Olaf came to an intersection in the hallway and looked left to the sound of an animal galloping. He turned and briefly saw Splinter, riding on top of Sven, speed past Olaf, causing his head to twirl. When it stopped, his head was turned 180 degrees. He quickly straightened it out, only to see three strange-looking creatures zip past him, causing his head to twirl around again.

After straightening his head again he wondered what happened, "Woah! What was that about? I think they went this way."

He went in the opposite direction.

Castle courtyard

Stockman-fly was now on the defensive in this fight as he continued to fly and Elsa continued to shoot blasts of ice-magic from her hands at him. He was an easy target from up here, so decided to fly downward, a big mistake on his part.

As soon as he descended his head almost came into contact with Leo's blade as he tried to swing his katana at the humanoid fly.

Stockman flew backward and almost backed into Raph and Kristoff as they tried to hit him with their weapons. He tried to fly back up only for Mikey and Donnie to jump and try and slam their staff and nunchuck on his head. He flew to the left towards the fountain but didn't see Karai coming at him from the top of the fountain and giving him a kick across his enormous bug-like face, knocking him back.

"ZZZ! I have had enough!" Stockman-fly screeched as made a beeline to Anna again and flew straight up, close to a window on the second floor of the castle, with her in his arms.

"Anna!" Elsa and Kristoff both exclaimed.

"Put her down, Stinkman!" Raph commanded.

"Thatzzz ZZtockman!" Stockman corrected, "And unlezzz you want another freak in thizz kingdom…"

Stockman reached with his left hand into his backpack, the princess in his right arm, and pulled out a familiar-looking container, "I zzzugezzzt you zzurrender !"

"Mutagen!" Donnie said, "Stockman's packing Mutagen!"

"Are you out of your mind, Stockman!?" Karai yelled.

Realizing what could happen, Leo was the first to prevent anything crazy from happening.

"Okay Stockman put her down," he assured, "Let's not do anything you'll regret."

"Yeah, don't do anything crazy," the hostage Anna added.

"I make the demandzzz now. You will do azzz I zzzay , or the girl mutatezzz with me!"

Elsa's eyes widened. She remembered how the Turtles told her this Mutagen stuff was dangerous and didn't want to wish that on her younger sister.

"No, please don't hurt her. Let her go, I'll do what you want."

"Elsa no!" Anna yelled, but Stockman pulled the glowing Mutagen container closer to her.

" Juzzzt come with me, and I will let her go," the mad scientist assured.

Olaf was now on the second floor and looked at an open window. He heard a buzzing sound and looked up to see Anna with a sort of bug-man.

"Hi Mr. Bug-man! I'm Olaf and I like warm hugs!"

Stockman-fly heard from behind. He turned and was startled at the sight of a talking snowman, so startled he dropped both Anna and the Mutagen vat.

"Anna!" Elsa, Mikey, and Kristoff yelled as she screamed.

Leo jumped and was able to catch Anna. He then bounced off the wall and jumped backward to everyone else, who gathered close in a circle.

The Duke found himself surprised. Despite his blurred vision and weakening body, he was able to navigate through the halls of the Arendelle castle. He weakly made it through the double doors leading out into the courtyard.

His vision was almost gone and was losing all feeling in his body.

"Arendelle… what have you… done to me?" he weakly said, unaware of the scorpion venom coursing through his veins.

"Anna!" he weakly heard.

He looked up and saw something glowing and green falling towards him.

The Mutagen sample shattered once it hit the Duke of Weselton and the glowing Mutagen spread all over his body.

He immediately began to scream.

The scream caught the attention of the four turtles, three girls, the ice miner, and even Stockman-fly.

They saw the Mutagen was now all over the screaming Duke of Weselton. He continued to scream as he fell back into the double doors inside the castle, the doors closing behind leaving only a crack. All that is seen and heard is a bright flash of green and a curling scream.

Then all was silent. Save for the buzzing of Stockman-fly.

"Was that the Weaseltown guy?" Raph asked.

"I think it was," Kristoff confirmed.

"How'd he get out?" Mikey wondered.

"I think that might be the least of our problems now," Karai said.

The double doors were sent flying off. The heroes ducked as they saw the doors crash into the fountain. They slowly turned to the open door, seeing only darkness.

"This can't be good," Leo said.

A figure slowly emerged from the shadows. It was the Duke, but now he was completely different; his new form shining in the moonlight. His skin was now a brownish-yellow color, his entire lower body was transformed into that of a scorpion, complete with eight legs and a scorpion stinger-tail. His upper body was human-like save for the scorpion claws in each hand, his face was almost the same, except for the mandibles in place of a mouth and onyx-black eyes.

He let loose an ear-splitting roar.

Chapter Text

Arendelle castle hallways

Master Splinter continued to ride Sven, who sprinted fast through the walls of the royal castle. Splinter turned behind and saw the three Squirrelanoids still in pursuit of him. One ran on all fours on the floor, the second on the right wall, and the third on the left wall. They were drawn to the scent of the reindeer's carrots that Splinter carried with him.

"Yes, beasts. Continue to follow me," Splinter said.

He would lure the beasts deep into the castle and deal with them so that his sons, daughter, and their friends wouldn't have to deal with them and they wouldn't go rampaging through the kingdom. He just hoped they would be alright without him.

Castle Courtyard

The Turtles, Karai, Elsa, Anna, and Kristoff, even Stockman-fly, looked in shock at the new mutated Duke of Weselton, now in the form of a scorpion. His whole body was tan-brown, his lower body was that of a scorpion, he had scorpion claws for hands, as well as mandibles in his mouth and onyx black eyes.

"Mutant scorpion," Donnie observed, "I guess we were due for one of those."

"Is that the Duke of Weasletown?!" Mikey yelled.

The mutant duke looked at his new body and was horrified at it, "What did you do to me!? I'm a hideous freak!?"

"A scorpion," Anna noted with contempt, "You know, that look suits him."

"But I think I prefer him as a normal guy," Kristoff said, "At least then he doesn't look so terrifying."

"Wow," Raph said, "I didn't think this guy could get any uglier."

"At least now we can beat him up and not feel guilty," Karai added as they both had their respective weapons ready.

"I'm juzzzt… gonna… take my leave now," Stockman-fly said as he flew away, not wanting to get caught up in this.

The metamorphosed Duke looked towards Queen Elsa, who was looking rather nervous. His look of shock became that of rage.

"You!" the Duke exclaimed as he pointed his right claw at her, "Monster Queen Elsa! You did this to me!"

Leo immediately stepped in front of Elsa with his blades at the ready. Anna did the same as well, though she had no weapon.

"Elsa had nothing to do with this, you jerk!" Anna said, defending her elder sister.

"Don't bother Anna," Leo told her, "This guy was already crazy before, but Mutagen's completely warped his brain, making him completely insane."

"So I'm guessing there's no talking out of this, is there?" Elsa guessed.

"Nope," Leo answered.

"This is all your fault! All of you! You hideous freaks and monsters! I'll RIP YOU ALL APART!" the mutant Duke yelled.

"Not gonna happen!" Leo declared as he charged in, but the Duke thrust his scorpion tail to Leo, who blocked it with his blades.

Leo was swept away by one of the claws, much to the shock of his brothers and Elsa.

The mutant scorpion turned to his enemies and growled.

Donnie came charging in next. He leaped high and brought his staff down, attempting to strike the Duke's head. The Duke blocked the attack with both his claws and shoved Donnie off.

Mikey came in next and whacked him in the chest several times with his nunchucks. The Duke tried to snap at Mikey with his claws, but Mikey jumped back.

The Duke then felt something hit his back. He turned his head 180 degrees and saw Raph on his back, jabbing his sais into his lower scorpion body, making the mutant shriek in pain.

This gave Karai enough time to run straight for the Duke and slash him across the chest with her sword. He growled in pain as she and Raph jumped back.

Leo came flying in and delivered a kick to the Duke's head, forcing him back. The Turtle brothers and Karai gathered together by one of the fountains.

"Is that all you got?" Mikey taunted.

The Duke responded by thrusting his tail forward and a stream of yellowish-green liquid came out of it. The stream impacted the fountain, causing the top of it to melt away, as if it were touched by acid. All looked in shock at this, Mikey especially.

"The answer I was looking for was 'yes'," Mikey said, fear evident in his voice.

The Duke attempted to run at the turtles with his scorpion legs but didn't get too far as the ground around him became frozen. He slipped a bit and looked to see a large ice dome freezing around him. The Duke looked to Elsa, shooting ice magic from her hands, sealing the dome.

"Well, that should hold him," Anna said.

The Duke then shot more acid out of his tail towards the wall of the dome and the whole wall melted away, much to Anna's horror.

"You just  had  to say something," Raph told her with a scowl.

"Oops," Anna smiled innocently.

The Duke turned his attention to the queen again and thrust his tail at her again, only for Leo to jump on her, pushing her out of the way. A chain wrapped around the duke's tail. He turned to see Mikey holding the chain. He lifted his tail and spun it around at a fast rate. Mikey screamed was pulled with the chain and spun at the speed of a helicopter blade.

He barely missed a hatchet blade towards his face, breaking his momentum, and tossing Mikey into Leo and Elsa; all three rolled on the ground away from the Duke.

As Kristof continued to swing at the Duke, Karai, Raph, and Donnie charged at the mutant scorpion and swung their weapons at him. All the Duke could do now was block as these four barely gave him an opening.

Anna came to Leo, Elsa, and Mikey as they got up.

"Dudes," Mikey began, "Scorpi-Duke is tough."

"'Scorpi-Duke'?" Elsa questioned

"You know. Cause he was a Duke, and now he's a scorpion so …"

"We get it," Elsa and Leo said at the same time.

"So mutagen turns people into stuff like that?" Anna asked

"Or worse," Leo replied

Anna and Elsa both shuddered at what could be possibly considered worse than this.

"Remind me not to ever touch Mutagen," the normal sister remarked.

"Will do," the ice queen replied.

Meanwhile, in the doorway to the castle, the whole fight was being witnessed by a certain snowman who was indirectly responsible for the current situation.

"Go Raph! Go Karai! Go Kristoff!" Olaf cheered.

Castle hallways

While ridding Sven, Master Splinter came close to a knight's armor that decorated the hall. He was able to swiftly grab the sword and looked behind to see the Squirrelanoids had yet to give up their relentless pursuit.

"Sven, turn now," Splinter commanded as the two came to a right turn.

Sven turned down the adjacent hallway.

Right as they turned, Splinter threw the sword back to the wall like a javelin. The timing was perfect. The sword impaled the mutant running on the wall, pinning the squirming creature to it. The other two looked to see their fellow mutant squirm before its limbs went limp and died.

The remaining two turned to Splinter who just got off of Sven and glared at the two as the creatures snarled at Splinter. Unfazed, and in one quick motion, he threw a shuriken upwards, severing a hanging chandelier.

The two looked up as it fell, one jumped out of the way and avoided it, while the chandelier crashed onto the other one , crushing it.

The last one tried to take its vengeance and leaped towards Splinter. Before it came close though, Sven kicked the creature in its side with his back feet, sending the Squirrelanoid into the wall. Before the creature had a chance to recover, Splinter jammed his blade into the creature's throat, killing it. As the creature went limp, Splinter sheaved his blade back into his cane.

"You did well Sven," Splinter congratulated as he reached into the sack he carried, "Enjoy your reward."

He handed a carrot to Sven who immediately, and gratefully, took it in his mouth and ate it. Sven then licked Splinter on the cheek, the old rat master smiled in amusement.

"Come," Splinter said, "My children and your friends may still need our help."

Courtyard

Donnie was tossed onto the ground. Raph came at the Scorpi-Duke from the air, sais at the ready, but the Scorpi-Duke swung his tail and sent Raph rolling on the ground. Mikey delivered an axe kick from behind onto his head, knocking him onto the ground, where his entire body (minus the head) was covered in ice, courtesy of Elsa.

Scorpi-Duke growled as he broke through the ice restraints with much effort.

"Is there anything that can stop his freak?!" Karai questioned.

"Just keep hitting him!" Leo told her as they both leaped towards him, only for the Scorpi-Duke to grab them both with his claws and throw them away.

Leo rolled on the ground, and Karai smacked into a fountain. The impact caused the top of the fountain to fall on top of her, pinning her to the ground and knocking her unconscious.

The turtles were all barely conscious, save for Mikey who was standing with Kristof, in front of Elsa and Anna.

"Okay, Scorpi-Duke…" Mikey began, "Maybe we can talk this over."

"Not on your life demon," Scorpi-Duke responded, "What's left of it anyway."

"That doesn't make any sense," Kristoff observed with a raised eyebrow.

"This guy never made any sense to begin with," Anna reminded.

"True."

The Scorpi-Duke lashed his tail out to the group, who split and scattered to all sides. He turned to Mikey as he wrapped his chain around his right claw. With his newfound strength, the mutant scorpion swung Mikey around and sent him flying into Raph who had just barely recovered. The two rolled on the ground before falling unconscious.

He then sprayed more acid from his tail towards Elsa, who pulled up an ice wall to block it. The wall quickly melted as the Scorpi-Duke charged at her. He didn't get too far as Anna jumped onto his back and wrapped her arms around his neck.

"Anna, get off of him!" Elsa yelled, but it was too late.

The Scorpi-Duke wrapped his tail around Anna and threw her into Kristoff. Kristoff caught her but was quickly swatted away by the Scorpi-Duke's claw.

With that done, the mutated duke turned to his target. He slowly came toward the fear-induced queen.

"Stay back!" Elsa yelled as she formed a large ice wall, separating the two.

The Scorpi-Duke merely bashed through it with his claws. Before Elsa could do anything else, he grabbed her hands with his claws and lifted her, spreading her arms wide.

He smiled with his mandibles as his tail slowly inched towards Elsa's face like a snake, the stinger inches from her face. She looked in fear as he pulled it back and lunged it at her head.

"STOP!" a voice demanded, causing the stinger to stop less than an inch from Elsa's face.

The Scorpi-Duke turned around to the not-so-pleased Master Splinter six feet away from him.

"You would attack a child? You have no honor. Face a true warrior!" Splinter challenged.

The Scorpi-Duke dropped Elsa, "Another monster for me to vanquish."

The mutated royal charged to his new enemy.

Elsa got back to her feet and saw Sven helping Anna and Kristoff.

"Is that Master Splinter?" Anna asked.

"Yes, it is," Elsa said with a smile, now with hope.

The Scorpi-Duke tried to bring both his claws down on top of Splinter, who merely stepped to the left out of the way as the claws impacted the ground. He tried to lash out with his stinger, but Splinter caught it and used the momentum to pull him in and toss him over his head.

Elsa, Anna, Kristoff, and Sven looked in amazement.

"Go Splinter go!" Olaf cheered from the doorway he was previously at.

The Scorpi-Duke snarled at Splinter, who only glared. He tried to snap and lash his claws at Splinter who was able to avoid all of them with little effort. Splinter gabbed the left claw as it lashed at him and twisted it the wrong way. He yelled in pain and tried to lash out his stinger, only for the rat sensei to bring the claw he was holding to the stinger as it impacted it. The Scorpi-Duke yelled in pain as Splinter delivered a fierce roundhouse knocking him back. Splinter then ran towards him and thrust his left hand, the index, and middle fingers sticking out. The fingers stopped less than an inch from the duke's chest, and an unseen force sent him flying into the wall toward the castle.

"Yes!" Anna cheered as Kristoff, Sven, and Elsa both had wide smiles as well seeing Splinter fight and seemingly beat the Scorpi-Duke.

Splinter turned with a smile towards the four. Karai had just woken up and saw what had taken place, even though she was still pinned down by the fountain, she smiled.

Elsa's smile soon turned to one of fear as she saw the stinger of Scorpi-Duke rise.

"Master Splinter, LOOK OUT!" she yelled.

Splinter turned and saw the stinger slash him across the chest, much to everyone's shock.

"Father!" Karai yelled.

Splinter held the wound with his hand and saw both claws grab Splinter painfully as he yelled. The Scorpi-Duke picked him up and threw him towards Elsa and the others. They all rolled on the ground, Anna closer to Karai.

Elsa's world was spinning and she could barely see the Scorpi-Duke coming closer to Anna, who was also dizzy. Karai looked up to the mutate and saw him pick Anna up.

Anna's point of view started to stop spinning and she looked in shock at the Duke holding her.

"You are even worse than her," he muttered, "You sympathize with a monster. Anyone who does so is no better himself, or herself."

"Let...me...go," Anna lightly said as she was still a tad dizzy.

Scorpi-Duke lifted his tail, ready to execute her, but felt someone pulling on one of his legs. He looked down to see the pinned Karai pulling on it. "Stop. Leave her alone!" Karai demanded.

"Be patient. You're next," the Scorpi-Duke told her as he shifted his attention to Anna, who was now struggling to get out of his grip.

Elsa was struggling to get up and tried to summon enough magic to stop him from hurting her little sister, but a certain voice stopped her and the Duke.

"I said…" Karai began, "…LEAVE. HER. ALONE!"

Her eyes had become reptilian slits. Her hand had turned into something that looked like a serpent and it threw Scorpi-Duke away, forcing him to drop Anna.

Both sisters looked to see Karai slip out of the fountain she was pinned to like a serpent. They looked in surprise as they saw her yell and she changed right in front of their eyes.

Her hands had become snakes and her lower body shifted to that of a serpent, her yell had become a snake-like hiss and Elsa and Anna looked in absolute shock, Elsa covering her mouth, as Karai had transformed into her mutant snake form.

The snake-Karai hissed at the Scorpi-Duke as he got back up.

"Another monster. This kingdom is full…"

Before he could finish, he was smacked across the face by Karai's tail and knocked back away with such force.

"You want monsssster…" the serpent-Karai began, "I'll ssshow… monssster!"

The snake then tackled the scorpion and the fight began.

"Karai?" Elsa questioned.

"She's a mutant too?" Anna asked.

"Ooh," Olaf spoke with a smile as he came to the sisters, "I didn't know Karai could do that."

"Neither did we," Elsa added, though more with concern in her voice. Is this the reason Karai shut herself out from them?

A male grunt was heard. They turned to Kristoff who was holding up the unconscious Splinter with a hand over his shoulder, with Sven pushing Splinter in the back, to try and keep him from falling.

"Kristoff," Anna said as she, Elsa, and Olaf quickly came to them.

"How's Master Splinter?" Elsa asked.

"He's out, but he'll be okay," he answered, taking notice of the fight between the snake and the scorpion.

"Are you kidding me?" he later questioned, "Now we gotta deal with some giant snake?!"

"Kristoff, that's Karai," Anna told him.

" That's  Karai!?" he exclaimed with complete and utter surprise.

The Scorpi-Duke lashed out with his claws at the serpent Karai, but she was far too quick. She lashed him across the face with her tail, knocking him back. She snapped at him with her snake-like hands, the mouths of her snake hands biting into his chest. He tried to bring his stinger into her, but she leaped over him. She slithered up the wall and onto the roof just above the gate leading into the town. He climbed up the wall with his scorpion legs and faced her at the roof.

Both predatory mutants stared each other down before snarling at each other and charging.

Leo rubbed his head before coming to. He held his aching side, still sore. But was helped to his feet by Kristoff and Anna.

"You okay Leo?" Anna asked.

"I'll live," he said.

He heard a hissing sound and saw the battle on the rooftop between Scorpi-Duke and Karai.

"Oh no," he said with horror.

"'Oh no'?" Anna asked, "I think this an 'oh yes' kind of thing."

"Yeah, look at her," Kristof said as Snake-Karai continued to lay the beat down on the Scorpi-Duke.

"She's kicking butt," the brunette cheered.

"You haven't seen her when she's like this," Leo said, "If she's like this too long, it won't end well."

"Leo?" Elsa began, "Why is she…?"

"I'll explain later. Right now, we have to stop her," the blue-clad Turtle told them.

Back on the rooftop, the Scorpi-Duke couldn't lay so much as a single hit on Snake-Karai, but every hit she had was a direct hit and it did quite a bit of damage. She snapped and smacked at him, far too quick and fast to keep up with. When forced back and getting enough distance, the Scorpi-Duke thrust his tail again, but Snake-Karai moved to the right and the tail missed, then she bit into it. He grunted in pain as she bit down even harder until a snapping sound was heard and she tore the stinger off.

Elsa, Anna, and Kristoff looked in shock at such a ruthless action. Leo was surprised but saw something like this coming.

The Scorpi-Duke screamed in pain. During this, Karai spat venom into his eyes. He stumbled back as his vision buried and he tried to rub his eyes with his claws. She then smacked him across the head with her snake body and sent him falling off the roof and onto the ground.

Karai then leaped down on top of Scorpi-Duke. She twisted each of her serpent arms around each of his claws and she snapped them, dislocating them, and spread them like a cross, and her tail twisted around his throat.

"No… more..." the Scorpi-Duke weakly uttered, "Please… mer… mercy..."

The pleas were all on deaf ears as she hissed at him and her grip around his neck tightened. Karai continued to stare down her victim as she strangled the life out of him.

"I can't stand this!" Anna said not liking what she was seeing at all. She ran towards Karai.

"Anna wait!" Elsa ran after her.

"Don't get near her!" Kristoff warned.

The Scorpi-Duke was just about out of oxygen and it looked like Serpent-Karai was about to obtain her first kill until…

"Karai stop!" Anna called out.

She turned her head to Anna, Elsa, and Kristoff as they ran to her.

"It's okay, stop! Please!" Elsa pleaded.

Karai let go of the Scorpi-Duke who had just fallen unconscious. Surprisingly she smacked Kristoff back, much to their surprise.

"Kristoff!" Anna yelled.

"Karai, what's gotten…" Elsa began.

Before the ice queen could finish, Karai wrapped her whole lower body around Elsa and Anna, tying their arms to their bodies and tying them together back-to-back.

"Karai, what are you doing?!" Anna yelled as she and her sister's bodies were tied in Karai's grip.

"It's us!" Elsa exclaimed, "We're not your enemy."

Karai merely hissed at them as her grip around the two tightened.

"Karai, it's me, Anna. Your friend," the princess began, "Okay, maybe not your friend, but an acquaintance…"

The grip tightened.

"We know each other… or maybe not… we don't know much about each other but…"

Karai tightened her grip around them even further.

"I… don't think… that's helping... Anna..." Elsa wheezed.

"My...bad..." Anna wheezed as well.

Kristoff got up and had a hatchet drawn and was about to fight, but Leo got in front and motioned him to stay back.

"Karai, it's okay stop," he said.

Karai's grip around the queen and princess loosed as she heard her brother's voice and looked at him.

"Just stop," Leo said, "It's okay, we're fine."

Karai hissed and looked like she was about to attack but…

"Miwa."

That voice made Karai's reptilian eyes go wide and she turned around to see Splinter limping and look to her with concern in his eyes.

"My child, it is alright… it is alright," he spoke in a soothing tone.

Karai released her grip on Elsa and Anna and slowly moved to Splinter. Leo and Kristoff stepped in front of them and watched the scene unfold. The serpent stopped in front of Elsa and slightly hissed at him.

"Miwa… do not let this animal instinct control you. Rise above it," he spoke to his daughter.

"It's okay, Karai," another voice spoke.

Karai turned to Mikey who was slowly walking toward her.

"It's me, Mikey, your brother."

"Karai, remember us," Donnie added as he slowly walked to her, "We're your family. Remember who you are."

Raph came up as well, "Come on Karai, you're gonna let your snake side push you around like this? The Karai I know would never take that kind of crap from anyone."

The turtles had regained consciousness and we're attempting to console their adoptive sister.

"Karai," Leo spoke, "Don't let this control you. You're stronger. Prove yourself stronger. Come back to us."

Karai seemed to have calmed down quite a bit as she lowered her defenses.

"Leo…" she lightly spoke.

"My child…" Splinter began as she slowly turned to him, "I am sorry this happened to you, I never wanted this for you. I am truly sorry. But no matter what happens, you are still my daughter, and I will always love you."

"Father…." Karai began.

She hissed in the air as her body began to shift and change again. She had retained her human-like appearance, save for snake scales covering her skin and reptilian silt eyes. She closed her eyes and her skin turned back to normal and her eyes opened to reveal human eyes.

Her brothers quickly came close to her, along with her father. Elsa, Anna, Sven, and Kristoff came close as well, but not too close as this was a family matter. Karai took a few deep breaths before looking around herself.

"Guys?" she said, rubbing her head, "What happened?"

"Oh! I know! I know!" Olaf spoke excitedly with a raised stick hand, "You became this cool snake, and then you…"

Raph and Donnie immediately shot Olaf a glare, fire in both their eyes. Olaf seemed to understand as his mouth closed, but the damage had already been done.

Karai gave a deep exhale, "I lost it again, didn't I?"

"Yeah," Mikey answered with sympathy in his voice.

The kunoichi looked down with guilt, "I'm sorry."

"Hey it's okay," Leo consoled, "You were trying to help us. None of us are hurt."

"You did beat up the bad guy, so thanks for that," Raph consoled in his way.

"We're all fine. Don't worry," Donnie said.

"Miwa, my child," Splinter said as he lifted her chin with his fingers, "You have your mother's spirit, and that will never go away no matter which form you take. And your family will always be here for you."

Karai immediately latched onto her father and buried her head in his chest. Splinter embraced her back as Leo, Donnie, Mikey, and even Raph put their hands on her shoulders.

Anna couldn't help but hold Kristoff's hand at the sight of this.

"Hug time?" Olaf said, wanting to get some of this.

Before he went over, Elsa put a hand on his shoulder, "Olaf, don't. Let them have their moment."

"Okay," Olaf said, still smiling.

While Elsa was glad things worked out, she couldn't help but feel a great sense of sympathy towards Karai. This was likely the reason she excluded herself from everyone else, but she couldn't help but wonder. 

Karai, what happened to you?
