Chapter Text

Class 1-A’s summer vacation had officially begun. After successfully completing their final exams, everyone was gathered at UA bright and early, waiting for the bus to arrive and take them to training camp. Everyone except Izuku Midoriya, that is.

Somewhere in the city… A snake-like villain thrashed wildly, his elongated arms and tail striking out at the police officers trying to contain him.

Officer 1: We have you surrounded! Surrender now, or we'll open fire!

The snake villain hissed, venom dripping from his fangs as he lashed his tail, knocking aside a police barrier.

Ssserpent: Who are YOU to challenge my might?

At that moment, a confident voice cut through the chaos.

Izuku: Hey Snakepit! Why don't you back off before I turn you into a handbag?

The snake villain's yellow eyes narrowed toward the boy. 

Ssserpent: You think YOU can sssstop me?

Izuku: Yep! Kinda do!

He slammed his hand down on the Omnitrix. In a flash of green light, Izuku was replaced by a large, armored alien curled into a ball.

"CANNONBOLT!!!"

Officer 1: Kid back away from there! He's dangerous!

Cannonbolt: It's not a problem guys! Creeps like this—uh, what’s your name?

Ssserpent: I am Ssserpent. The snake that walks like a man.

Cannonbolt tucked his limbs in and began to spin. He shot forward, crashing into Ssserpent with enough force to send him flying into a nearby wall. Ssserpent groaned, dazed. Cannonbolt rolled back and hit him again for good measure.

Cannonbolt: Is it okay if I call you "Roadkill", the snake that only made it halfway across the street?

Ssserpent: Urgh...

Cannonbolt: I’ll take that as a yes.

Ssserpent slumped to the ground, unconscious. Cannonbolt unrolled and waved at the officers.

Cannonbolt: He’s all yours!

Meanwhile at UA, most of Class 1-A was lounging near the bus stop, chatting and stretching as they waited. Iida tapped his foot impatiently, checking his watch. 

Iida: The bus will be here any minute. Where on Earth could Midoriya be?

Ochako: Knowing Deku? He’s probably fighting some off-world chump or… maybe he overslept again.

Iida: Fighting a what?

Ochako: Nothing!

Just then, a blur of blue streaked across the courtyard, kicking up dust and wind as it skidded to a halt in front of the group.

XLR8: Sorry I’m late!

The Omnitrix beeped and flashed red as Izuku shifted back to normal. He stretched his arms, looking far too relaxed for someone who had just been in a fight.

Izuku: Got here as fast as I could.

Iida: You’re late! That watch of yours doesn’t keep very good time, does it?

Deku just shrugged as he glanced at the Omnitrix. 

Izuku: Might need a new battery.

He winked at Ochako, who giggled.

Iida: Now then... EVERYONE! THE BUS IS HERE! LINE UP IN SEATING ORDER!

As everyone boarded, Aizawa stood at the front of the bus, arms crossed, looking as half-awake as usual.

Aizawa : Here’s the deal. We’ll be on this bus for about an hour before our first stop. Stay focused and—!

No one was listening. Sero and Kaminari were arguing about who had the best support gear, Kirishima and Ashido were arm-wrestling, and Iida was frantically yelling at Aoyama to stop standing in the aisle.

Aizawa: Why do I bother?

Kaminari leaned over the back of Izuku’s seat.

Kaminari: So, Midoriya… how many forms are you up to now?

Izuku’s eyes lit up. He immediately pulled out his notebook, flipping through it with practiced ease.

Izuku: With the last six I unlocked, I’m up to… 27!

Kaminari: Damn, 27?!

Izuku: And counting. Honestly, I’m not sure if there’s even a limit anymore.

Mina: Yeah, I’ve been wondering—how exactly does your quirk work? Do you make up the forms in your head and transform or what?

Izuku froze. He rubbed the back of his neck, suddenly feeling everyone’s eyes on him.

Izuku: O-Oh! Uh, well… it’s kinda like a subconscious thing, I think? The forms just… come to me when I need them. Yeah! That’s it!

Yaoyorozu: And the watch stabilizes them?

Izuku: Yeah! Just a support item! Nothing really fancy or anything that anyone needs to get worked up over, right? Hehehehe...

Everyone just stared at him. Izuku smiled awkwardly as a bead of sweat rolled down his face. Aizawa was seething on the inside, hearing Izuku lie terribly. Ochako leaned across the seat, changing the subject.

Ochako: Man, this is gonna be so much fun! Tell me you brought it.

Izuku smirks as he pulls out a handheld gaming device.

Izuku: You didn't think I forgot about Sumo Slammers Smackdown 3 did ya?

Izuku smirked and pulled a handheld console out of his bag. They quickly booted up the game, huddling close over the screen.

Ochako: You're so going down, Doofus!

Izuku: In your dreams, Dweeb! Hey Shoto! You want next game?

Todoroki: ...What's Sumo Slammers?

Deku's eyes lit up as he hears this.

Izuku: *gasp* I GET TO INTRODUCE YOU TO THE SUMO SLAMMERS?!

Ochako: Hoo boy this is gonna be a long trip.

About an hour later, Izuku was still talking as Todoroki sat quietly, listening but looking very lost.

Izuku: -and then there's Sumo Slammers: Hero Generation, which is like a weird sort of soft reboot of the original franchise. It's five years later and the bad guy Kenko teams up with Ishiyama and-!

Ochako: You gettin' all this, Shoto?

Todoroki: Maybe every fifth word or so...

Suddenly, the bus came to a stop at the edge of a cliffside.

Aizawa: Alright everybody out. Don't bother getting your things, this is just a quick stop.

Mineta: *having to use the bathroom* Oh sweet release!

The students filed out, stretching and looking around.

Izuku: Huh, this doesn't look like a rest stop...

Ochako: Shouldn't the other class also be here?

Kaminari: What? No quick-mart? You mean I got off the bus for nothing? Aw screw this, I'm getting back on.

Kaminari tried to get back on the bus, but the doors wouldn’t budge.

Kaminari: Hey, what gives?!

Kirishima: Dude, just open it.

Kaminari: I'm... trying!

Aizawa: You didn't think this trip would just be all fun and games, did you?

Everyone:...Huh?

Mina: Uh... what does he mean by that?

Mineta: More importantly... where are the bathrooms?

Aizawa: This isn't just going to be a summer camp. This is a training camp. You'll be working hard every single day you're here to master your quirks.

Everyone: WHAT?!

Kaminari: But we've been doing that all year long!

Mina: Then what was even the point of passing the final if we were always just gonna do more work anyway?!

Just then, two girls in cat-themed hero costumes appeared on the cliffside.

Izuku: WOAH! It's the Wild Cats! The pro-hero team!

Aizawa: These two are here to assist you in your training. Meet the Wildcats, Mandalay and Pixie-Bob.

Mandalay: It’s a pleasure to meet you all.

Mandalay, the more composed of the two, gave a polite nod. Pixie-Bob, on the other hand, beamed with excitement.

Pixie-Bob: OH MY GOSH, LOOK AT YOU FRESH-FACED LITTLE BABIES! I’M SO EXCITED TO SHAPE YOU INTO PRO HEROES!

The class stared, while Jiro muttered under her breath.

Jiro: …Did she just call us babies?

Pixie-Bob, completely ignoring the weird looks, clapped her hands.

Pixie-Bob: Alright, kiddos! Time for your first exercise!

Mandalay: The camp is still a long way from here. Your task is to make it there on foot.

Everyone: …Wait. What?

Mina: W-Wait. We’re not about to have to—!

Mandalay: *smirking* You heard me. No bus rides. No shortcuts. You’ll be traversing the terrain yourselves.

Mineta: You’ve gotta be kidding! It’s gotta be, like, a five-hour hike!

Mandalay: Oh, it won’t be just a hike. You’ll be navigating the terrain, avoiding obstacles, and dealing with the… wildlife.

Asui: Ribbit… What do you mean, “wildlife?”

Pixie-Bob: Oh, and there’s a time limit! Anyone who doesn’t make it by sundown won’t be getting dinner!

Izuku: WAIT, HOLD ON—!

Ochako: No dinner?! THIS IS ABUSE!

Iida: NO ONE SAID ANYTHING ABOUT STARVING US!

Izuku: Maybe we should... get back on the bus. 

 Kirishima: I'm with ya on that, bro. 

Pixie Bob: Oh no ya don't! 

The students turned back toward the bus en masse, but before anyone could even think about getting back on, Pixie-Bob slammed her hands into the ground and BOOM! The earth erupted beneath them, sending them flying into the air with screams and shouts of shock.

Everyone: AAAAAAAAAAAAAAAAAAAHHHHHHHHHH!!!

They tumbled down the cliffside. Izuku managed to twist mid-fall and grab Ochako and Todoroki’s arms, steadying them as they hit the ground below.

Izuku: Oh man, that sucked.

Iida: Nnh… is anybody hurt?

Ochako: Just my pride.

Jiro: And possibly my ribs.

Mineta: Well, on the bright side... I don't have to use the bathroom anymore.

Jiro: Ew!

From the cliff above, Aizawa peered down at them, his usual deadpan expression intact. Pixie-Bob cackled at them from above

Pixie Bob: You'll have to get through Beast's Forest if you wanna get to the camp!

Mandalay: Good luck everyone!

Mina: Uhhh... why's it called Beast's Forest?

Music Insert:

As if in direct response, the earth rumbled violently, and from the dense greenery ahead, a massive creature erupted from the ground—a hulking beast of dirt and rock, its form shifting and twisting as if the land itself had risen to fight them. Mina let out a very undignified scream.

Mina: AH! W-W-WHAT THE HECK IS THAT THING?!

Izuku: It's about to be roadkill! Going hero!

Izuku slammed down the Omnitrix, attempting to transform into Cannonbolt but instead morphs into his Appoplexian form. 

"RATH!!!"

Rath: LEMME TELL YA SOMETHIN', OMNITRIX! RATH IS SICK OF YOU NOT WORKING RIGHT! IT’S NOT EVEN FUNNY ANYMORE!!

The monster roared and charged Rath, who snarled, leaping forward and slamming his fist into its chest, sending chunks of dirt and rock flying—but the damage was short-lived as the monster’s form reshaped itself almost instantly.

Ochako: Oh great… it regenerates.

Kaminari: Ugh, I hate those!

Iida: We can't let that thing get back up! Hit it all at once!

Bakugou: DON'T TELL ME WHAT TO FUCKING DO!

Bakugou charged at the monster and launched a barrage of explosions at the creature’s head while Rath tackled its legs. Iida blurred into view, landing a Recipro Burst kick to its head with a sharp crack! The monster let out a shuddering groan before crumbling into dust.

Rath: And stay down!

But then—more rumbling. A dozen more sets of glowing eyes blinked from the forest ahead, followed by a chorus of guttural growls.

Ochako: How many of them do you think there are?

Tokoyami: And more importantly, how do we plan on getting past them? I have a feeling it's only going to become more difficult from here on out.

Todoroki: Looks like the head is their weak point. We take those out and the rest of it falls apart.

Kirishima: That's a lot of heads to bust, bro. And aside from that, we don't have a clue where we're going.

Yaoyorozu: Jiro, Shoji—use your quirks to locate the densest groupings of monsters. The more guarded the area, the more likely it's the right path.

Kirishima: Good thinking!

Jiro pressed her jacks to the ground. A low hum vibrated through the dirt as Shoji’s tentacles spread out, scanning the area.

Jiro: Okay, 'bout seven more monsters headed north!

Rath: On it!

Rath charged into the forest, shattering trees as he plowed through the monsters. Kirishima hardened his arms and rushed alongside him, smashing the beasts with his fists.

Kirishima: Take this ya big dirt clods!

Tokoyami: Dark Shadow go!

Dark Shadow surged forward, slicing through two of the creatures in one sweeping motion. Iida dashed in next, using Recipro Burst to deliver a powerful spinning kick that shattered another’s head.

Kaminari: Here goes! 1.3 Million Volts!

Electricity arced from Kaminari’s body, frying another monster in place as Jiro sent a soundwave directly into its weakened head, making it crumble into dust.

Kaminari: Nice one!

Mina skated across the dirt, spewing acid at the monsters, and covering created an acidic veil around herself and Hagakure. The acid melts the monsters' limbs and torsos, causing them to falter. 

Mina: Momo—cannon!

Yaoyorozu summoned a cannon and fired a concentrated blast into a cluster of monsters. Ochako followed up with an energy whip, latching onto one monster and hurling it into the others like a wrecking ball. They shattered on impact.

Hagakure: YAO-MOMO FOR THE WIN!

Mina: That’s how it’s done!

Ochako: Now it's ur turn!

Ochako lit up her hands and blasted the ground, launching herself high into the air, above the monsters. She then created glowing platforms beneath her feet and kept running above the trees. She lashed an energy whip at one of the monsters and swung it away with all her strength, sending it flying into the other dirt monsters like a wrecking ball. 

Asui: Nice one, Ochako! Ribbit!

On the other side of the forest, Bakugou and Todoroki were clearing a path together. Todoroki froze the legs of a monster, and Bakugou launched an explosion directly into its face.

Bakugou: DON'T GET IN MY WAY HALF 'N HALF!

Todoroki: I'm not in your way.

Bakugou growled, but they managed to clear another path. They're making progress, but there's still a lot of monsters and a long way to go. From a cliff high above, Pixie Bob is watching over the chaos as she's controlling all the monsters from a distance.

Pixie Bob: Hahaha! You're no match for me, you hero wannabes!

Back on the ground, Rath led the way, running and jumping through the forest, boosting himself with Full Cowling. 

Rath: Lemme tell you something forest dirt clod monsters! Ain't nothing you can throw at Rath, that Rath can't stop! So you should just give up now before Rath turns you into fertilizer!

The Appoplexian barreled through the forest until he reached a clearing and skidded to a halt before an enormous dirt titan—twice as large as any of the others.

Rath: Rgh! Lemme tell you something, gigantic forest dirt monster created by pro hero Pixie Bob, specifically made to stop me! You might be big BUT RATH IS EVEN BIGGER!

The monster steps forward approaching Rath, causing the ground to shake as he does.

Rath: 'Cept for the part where you're taller and heavier than me. BUT THAT DOESN'T MATTER! 'Cause the bigger they are, the harder-!

The titan raised a massive fist and swung—smashing Rath into a tree. Rath peeled himself out of the bark with a snarl.

Rath: The bigger they are, the harder they fall! That's what Rath was gonna say! RRRRRRAAAAAAAAHHHHHHH!!!

Rath leapt onto the monster’s back, going wild and digging his claws in. He furiously pounded the titan’s head over and over, while going on another rant. 

Rath: Is that all you got, 'cause Rath's got tons more. In fact I should give you some of mine so it'll be a fair fight. Then after that, everything I gave you, I could take it back again, AND MAKE YOU LIKE IT!

Kaminari: Y'know Rath is the only transformation that makes me wanna grab a box of popcorn, kick back, and just watch.

Jiro: Dude, this isn't the time for... Okay, me too.

After another brutal beating, the titan buckled and crumbled under Rath’s onslaught. The Appoplexian stood atop the beast's remains and let out a mighty roar that shook the entire forest.   Finally, after what felt like hours, the class stumbled into a clearing—dirty, bruised, but triumphant.

Mandalay: Wow, nice work! I was expecting you guys to show up MUCH later.

Izuku dragged himself forward on his hands and knees, completely drained.

Izuku: *panting* Ugh... Somebody... get me... a smoothie.

Mandalay: Gotta admit, I underestimated you all! As a reward for your hard work...

She reveals to them whole tables full of wonderfully prepared food which the class drools at and celebrates.

Kirishima: Woah! Look at all of that!

Ochako: I know! I think I'm in heaven!

Mina: Someone pinch me, I'm dreaming!

Pixie Bob: Enjoy this now kids 'cause tomorrow will be brutal!

The others start eating like there's no tomorrow. Pixie Bob then finds Izuku, Iida, Todoroki, and Bakugou to congratulate them. 

Pixie Bob: You four did pretty well, especially you. That tiger form of yours was pretty powerful, and you were all efficient in taking out that first monster.

Izuku: Oh, thanks!

Bakugou: Whatever.

As she's praising them, Izuku suddenly notices a small boy standing by himself.

Izuku: Uh, hey? Who's the kid? Are one of you guys his mother?

Mandalay: This is my nephew, Kota. Kota, say hi to our new hero trainees! They'll be here with us for the next week!

Kota just glares at them, not saying anything. Izuku squats to get on his level and introduce himself.

Izuku: Hey there! My name's Izuku Midoriya! I'm from the UA High School Hero Course. It's nice to meet you!Deku smiled warmly, crouching down slightly as he extended a hand.

Before he could finish, Kota punched him right in the groin. Deku’s entire body seized up and a high-pitched, almost inhuman squeal escaped his lips as he collapsed to the ground, clutching his groin.

Mandalay: Kota!

Every male in the class collectively winced, their legs instinctively crossing. Ochako rushed to Deku’s side.

Ochako: DUDE!!! Are you okay?!

Izuku, still curled up in agony, could only whimper.

Deku: He punched me in the dick… why? Why did he punch me in the dick?

Iida rushed to Izuku’s side as well and immediately pointed a shaking finger at Kota.

Iida: How dare you! You fiend of a child! A punch to the scrotum is UNFORGIVABLE!!

Kota, completely unbothered, scowled down at him.

Kota: I don’t wanna hang around with a bunch of wannabe heroes.

Iida: W-Wannabe?! How old are you kid?!

Bakugou, watching from the sidelines, smirked slightly, crossing his arms.

Bakugou: Hah! Kid’s got guts.

Todoroki: Oh, so that’s what you were like as a child?

Bakugou: Er-! THE HELL DID YOU JUST SAY, ICY HOT?!

Later that evening, after a long day of training, the students settled into their cabins. Outside, Kirishima, Mina, and Kaminari sat around a crackling fire, roasting marshmallows while Jiro strummed a soft tune on her guitar. Laughter and chatter filled the camp as exhaustion gave way to relaxation.

Inside his cabin, Izuku was unpacking when a gentle knock came at the door.

Mandalay: Midoriya, are you in here?

Izuku: Oh Ms. Mandalay.

She stepped inside, arms crossed, a faint smile on her face.

Mandalay: Hey! Listen... I wanted to apologize for Kota's behavior before. Unfortunately, he's often like that.

Izuku: Oh. That. It's alright, but can I ask you something?

Mandalay: Yeah, what's on your mind?

Izuku: Well I was just wondering, how come Kota doesn't like heroes?

Before Mandalay could answer, Pixie-Bob appeared in the doorway, arms crossed.

Pixie-Bob: It’s because of what happened to his parents. They were pro heroes, the duo known as Water Hose."

Izuku:Wait… Water Hose? I remember reading about them. They were killed in action protecting civilians."

Mandalay sighed, sitting on the edge of a bunk.

Mandalay: They were praised by the world as true heroes, but that's not how Kota saw it. He was so young when it happened. Too young to understand everything. As you can imagine, their deaths took a toll on him. All he knew was that his parents went to work one day and never came home. He believes they chose their duty over him. And ever since, he’s resented heroes for it. With his parents gone, he's been living with us but... It hasn't been easy for him.

Izuku: I can imagine. I don't know what I'd do if I lost my mom like that... 

He clenched his fist, then looked up at Mandalay with newfound resolve.

Izuku: Ms. Mandalay, if it’s okay with you, I’d like to try and show Kota what heroes really stand for. I want him to understand why we fight.

Mandalay studied him for a moment before a small smile crossed her lips.

Mandalay: I don’t know how you plan to do that… but if you find a way, I’d be grateful.

Izuku grinned and gave her a determined thumbs-up.

The next two days were intense as Class 1-A underwent rigorous training. Each student was pushed to their limits with specialized regimens designed to refine their quirks. Izuku worked tirelessly, balancing his One For All training with his alien transformations, learning new techniques and ways to combine abilities. Ochako honed her energy manipulation, expanding her control and experimenting with new constructs. By the end of each day, they were left exhausted but stronger than before.

That evening, after a hard day’s work, the students were tasked with making their own meals. The scent of curry filled the air as they gathered around makeshift cooking stations, joking and laughing despite their exhaustion.

Pixie-Bob: Alright, listen up, kiddos! Tonight, we’re doing something fun. A little classic, a little spooky…

Mina gasped, her eyes lighting up.

Mina: Oh my gosh, I KNEW IT! IT’S A TEST OF COURAGE, ISN’T IT?!

Kaminari and Kirishima fist-pumped in excitement.

Kirishima: AW YEAH, THIS IS GONNA BE AWESOME!

Pixie-Bob: You got it! Here’s how it’s gonna work: One class will enter the forest first and set up scares for the other class. The second group will then walk through the forest, trying to find name tags hidden within the trees. To win, the scarers must frighten as many students as possible, while the scarees must retrieve their own name tag to prove they braved the course! We’ll swap turns every 15 minutes. First up? Class 1-B will be the scarers!

The students murmured among themselves. Some looked excited, others… not so much. Kirishima grinned, cracking his knuckles.

Kirishima: Bring it on!

As pairs were quickly being formed, an urgent voice cut through the night.

Mandalay: Kota! Kota, where are you?!

Izuku immediately turned toward her.

Izuku: Ms. Mandalay? What’s wrong?

Mandalay: Ugh, Kota ran off again. He does this sometimes, but I don’t like him being out alone at night. He could get hurt.

Izuku’s expression hardened with determination.

Izuku: Don’t worry, I’ll find him!

Mandalay: How exactly do you plan to do that?

Izuku: I'll track his scent!

Izuku smirked and activated the Omnitrix, slamming down on the dial. Green light engulfed him as his body shifted and transformed.

*transformation sequence*

When the glow faded, a large, orange, canine-like creature stood in his place, sniffing the air. Ochako grinned mischievously before deepening her voice.

Ochako:WILDMUTT!!!

Wildmutt turned toward her, tilting his head in confusion. The others looked at Ochako just as bewildered.

Ochako: ...Well, he can't talk! Somebody had to do it!

With a few sniffs, Wildmutt caught Kota’s scent and took off into the night, bounding through the trees.

Ochako: I hope they'll both be okay.

Mineta: Well, he'll be fine. As long as he doesn't run into... the Yenaldooshi.

Iida: The what?

Mienta: *gasp* You guys don't know?

Yaoyorozu: Know what?

Mineta: The story of Yenaldooshi!

Jiro whacks Mineta in the head.

Jiro: Stop trying to scare us, the Yenaldooshi's just a myth.

Ochako: What's a... Yanodookie?

Mineta grabs a flashlight and puts it up to his face.

Mineta: Legend tells about a horrifying monster living in these very woods. The Yenaldooshi. Half man, half wolf, all terror. The Yenaldooshi usually lives in solitude, living out its days hunting and sleeping, but when people enter its domain... that's when things get ugly. The Yenaldooshi can smell intruders up to a hundred miles away and with built-in night vision, plus its sharp teeth and claws it's the perfect killing machine. You won't even see it before it's too late.

Some of the students got legitimately getting scared while the others didn't believe him.

Kaminari: Get real. If a giant wolfman was hiding somewhere in these woods we would've noticed by now. We've been here for days!

Mineta: That may be true, BUT we've never been out here at night. The Yenaldooshi is a nocturnal killer, meaning nighttime is playtime. And we're in its playground now.

Ochako: Pfft! Hahahahaha! Oh no! The big bad wolf-man is coming after me! Whatever will I do?

Jiro: Oh! I'm shaking in my boots I'm so scared! Hahaha!

Mineta: You should be scared! We're disturbing the Yenaldooshi! He could show up anytime and eat us all! But that's not even the worst part!

Jiro: *sarcastically* Really. Then what's that?

Mineta: The worst part is when it doesn't kill you. One bite from the Yenaldooshi will pass on it's curse. It's saliva infecting your bloodstream as your mind falls to its primal instincts. Friends and family become unrecognizable, as they become your prey, and before you know it... dinner.

Everyone:...

Bakugou: That's got to be THE dumbest story I have ever fucking heard.

They all walking away to start the game, leaving Mineta by himself.

Mineta: Mock me now, but don't come crying to me when you all end up dead!

While this is going on, Wildmutt is still racing through the forest, searching for Kota. The Vulpimancer sniffs the air for a moment before picking up his scent and dashing through the bushes. As Izuku transforms back into his human form, he spots Kota sitting alone at the edge of a cliff, gazing out at the night sky. The boy’s small frame is hunched over, lost in thought.

Izuku: Hey Kota?

Kota stiffens before turning to glare at him, annoyance clear in his eyes.

Kota: What do YOU want?

Ignoring his hostility, Izuku kneels down and places a plate of curry beside him.

Izuku: I saw you out here by yourself and figured you hadn’t eaten.

Kota scowls, looking at the plate with disdain.

Kota: I don’t want your food. Now leave me alone.

Izuku exhales, refusing to let Kota’s anger push him away. Instead, he takes a seat nearby, giving him space but making it clear he isn’t leaving just yet.

Izuku: So… your parents were Water Hose, huh?

Kota: Aunt Mandalay told you, didn’t she?

Izuku: Yeah… but I actually knew about them before. They were incredible heroes. I… I’m really sorry for your loss.

Kota: I don't care. "Sorry" doesn't bring them back... They're gone. They're never coming back. They left me here all alone.

Izuku stays quiet, letting him speak.

Kota: I hate it here. I hate living in this stupid hero world with these stupid quirks and fake heroes. All I see are people using them to hurt other people. I don't want to be a part of that.

His words strike a familiar chord in Izuku’s mind. He remembers another person who once spoke of false heroes.

" I told you before, kid. You’ve got the true makings of a hero. Not like these other fakes and frauds."

Izuku snaps back to the present, glancing at Kota with newfound understanding.

Izuku: I think I get what you mean.

Kota frowns.

Kota: Yeah right.

Izuku leans forward, resting his arms on his knees.

Izuku: You remind me of someone I used to know… a kid who thought the world had left him behind. That his dream would never come true. He was stuck in the background, convinced he’d always be invisible while heroes rushed past him. But one day, he realized something—

Kota watches him now, though his expression remains guarded.

Izuku: He realized he didn’t have to accept the world as it was. That he had a choice. He could let everyone ignore him, or he could stand up and make them see him. He decided that no matter what, he was going to chase his dream… even if the whole world stood against him.

A long silence stretches between them before Kota speaks.

Kota: Why are you telling me this?

Izuku: Because I know how it feels when the world seems unfair. I know what it’s like to feel powerless. But you’re wrong about something, Kota. You’re not alone.

Kota clenches his fists but doesn’t respond.

Izuku: It’s okay to be angry. It’s okay to feel lost. Life isn’t fair. Sometimes, it’s downright cruel. But every time it knocks you down, and you get back up, you become stronger. And one day, when life throws something at you again… you’ll be ready to throw it right back.

Izuku gets up and dusts himself off, leaving the plate of curry beside Kota.

Izuku: Maybe I'm just rambling. I'm not asking for us to be friends. I won’t push you to believe in heroes. But just… think about what I said, okay?"

He turns to leave but pauses, looking back one last time.

Izuku: For what it’s worth… I really am sorry about your parents. And I think that if they could be here right now, they’d tell you everything’s going to be okay.

With that, Izuku walks away, leaving Kota alone with his thoughts. His glare isn’t as sharp as before. As Izuku makes his way through the woods, a sudden rustling sound makes him stop in his tracks. Twigs snap under unseen footsteps and he tenses.

Izuku: H-Hello? Is anyone out there?

He only hears silence. Then a heavy breathing. Deku's pulse quickens.

Izuku: Ochako... if this is another prank, I'm not falling for it!

No response. Then, a faint purple glow flickers in the distance. Two glowing dots—eyes—emerge from the darkness. Izuku takes a shaky step forward.

Izuku: O-Ochako…?

Before he can react, a massive shadow bursts from the bushes, knocking him to the ground. As he scrambles back, he looks up—into the snarling face of a giant, monstrous werewolf.

Izuku: Not Ochako! NOT OCHAKO!!!

Chapter Text

Izuku: Ochako... if this is another prank, I'm not falling for it!

No response. Then, a faint purple glow flickers in the distance. Two glowing dots—eyes—emerge from the darkness. Izuku takes a shaky step forward.

Izuku: O-Ochako...?

Before he can react, a massive shadow bursts from the bushes, knocking him to the ground. As he scrambles back, he looks up—into the snarling face of a giant, monstrous werewolf; the legendary "Yenaldooshi" from Mineta's story.

Izuku: A werewolf?! Wait, no that can't be it. Maybe it's an alien or a quirk?

The beast growls before lunging at him, claws slashing through the air. Izuku barely dodges, rolling to the side.

Izuku: Whatever it is, it's definitely not friendly!

He slams the Omnitrix, engulfing himself in a green flash. The werewolf snarls, looking around for its prey—only to be caught off guard as thick roots shoot up from the earth, wrapping tightly around its limbs.

Swampfire: Tag! And you're it, Fang Face!

The werewolf thrashes and bites through one of the vines.

Swampfire: Argh! So you wanna fight dirty, huh?

Swampfire tightens his grip, then suddenly dives underground, dragging the beast with him.

Swampfire: Going up!

In an instant, they erupt from beneath the earth, launching the werewolf high into the air. The creature slams into the trees before hitting the ground with a heavy thud. Swampfire wastes no time, hurling a barrage of fireballs toward it.

Swampfire: How do ya like them apples?

The werewolf growls but doesn’t attack again. Instead, it retreats into the forest, disappearing into the darkness.

Swampfire: Yeah you better run!

He taps the Omnitrix and reverts to his human form, watching the treeline.

Izuku: I wonder what that was all about. I should go make sure that Kota's okay.

As if the universe answered, Izuku hears Kota scream.

Kota: AAAAAAAAAAAHHHHHHH!!!

Izuku: KOTA!!!

Without hesitation, he takes off running, pushing his legs to their limit. Meanwhile, Kota stares in horror at the massive, muscular man towering over him. The villain cracks his knuckles, grinning.

Muscular: Well look here. I came scouting for a nice vantage point and here I find someone not on our list. Hey kid. That's a nice hat ya got there! Wanna trade for my mask!

Kota’s breath hitches. He knows that voice. That grin. The jagged scar across his face. Memories of his parents flash in his mind.

Kota: It's you!... Papa... Mama...

He tries to run away but Muscular stops him, laughing menacingly.

Muscular: I think you and me should have some fun up here kid! Ready?!

Terror grips him, and he tries to run, but Muscular grabs his wrist with crushing force. Kota shuts his eyes, trembling as Muscular pulls back a fist, but before the punch lands, a blur of green crashes into them.

Izuku: I got you!

Rolling across the ground, Izuku shields Kota as they come to a stop. He quickly checks the boy—shaken, but unharmed. Rising to his feet, Izuku glares at the villain standing before him.

"Crap. I didn't actually think I'd run into a villain up here. And even if I call the others, they can't get here quick enough. Can't rely on any reinforcements. Dammit, I've got to stop this guy and protect Kota at the same time!"

Izuku turns back to Kota, his gaze firm. He smiles to reassure him. 

Izuku: Kota... I promise you... everything is going to be okay...

Music Insert:

Izuku activates the Omnitrix and starts dialing up an alien.

Izuku: I swear on my life... I'm going to save you Kota!

Muscular: You'll save him, huh? Sounds like something a hero would say. Your kind always rattle on about justice and all that. Wait... I know you. The brat from the USJ. The all powerful Deku, am I right? Now you WERE on the list! Hehehe, this should be fun!

Izuku: Rgh!

Muscular: Hehe, oh yeah. Shigaraki told me all about you! He told us he wants you alive, but he did say I could rough you up a bit first. Oh, and I think you've already become acquainted with my partner.

The villain whistles and a low growl rumbles through the trees. Izuku’s eyes widen as the massive werewolf from before leaps down from the cliff, landing beside Muscular.

Izuku: That's the monster I fought earlier!

The werewolf snarls, baring its fangs, ready to pounce, but Muscular holds him back. 

Muscular: Hahahaha! Easy, Crujo. You've done your part. *he cracks his neck* This one's MINE.

Izuku: You're not touching him.

Izuku clenched his fists, standing firm as Muscular grinned, his grotesquely engorged muscles flexing in anticipation.

Muscular: That's fine! I'll play with you first! SHOW ME WHAT YOU'VE GOT SQUIRT!

As Muscular charged, Izuku slammed the Omnitrix. In a brilliant flash of green light, his form shifted, expanding into something massive. Kota's eyes widened as he looked up at the towering Vaxisaurian.

"HUMUNGOUSAUR!!!"

Muscular: Huh?

Muscular skidded to a halt as Humungousaur smirked. 

Humungousaur: Pick on somebody your own size!

With a mighty swing, Humungousaur drove his fist into Muscular’s gut before whipping around to smack him across the face with his tail. Muscular staggered but remained on his feet.

Muscular: You hit pretty hard for a kid! Shigaraki told me about you. My quirk lets me power up my muscles and get stronger!

He starts engorging his muscles, growing larger.

Muscular: Meaning this should be fun! Hahahaha!!!

He lunged again, and the battlefield erupted into chaos. Each clash of their fists sent shockwaves through the forest. Humungousaur’s sheer size and strength gave him an advantage, but Muscular was relentless. The two locked hands, straining against one another, trying to force the other back.

Muscular: Oh yeah, I forgot to mention; I'm also looking for a kid named Bakugou. You seen him around?

"They're after Kacchan too?"

Humungousaur growled, delivering a bone-crunching punch that sent Muscular tumbling. The villain rebounded and came in swinging, but Humungousaur sidestepped, grabbing his arm and slamming him into the ground.

Muscular: I'll take that as an "I don't know". Perfect!

With a savage kick, he sent Humungousaur staggering before unleashing a brutal flurry of punches. The Vaxasaurian slid backward, barely keeping his footing.

Muscular: More playtime for me!

Muscular’s muscles swelled further as he continued his relentless assault. Humungousaur held his ground, their fists colliding with a thunderous boom.

Humungousaur: Is that all you've got, Tiny?

Seething, Muscular attacked with even more ferocity, but Humungousaur countered with rapid, punishing strikes. The two of them continued exchanging blows before Humungousaur threw a devastating uppercut launched the villain into the air. Before Muscular could recover, Humungousaur slammed his tail into the ground, triggering a tremor that sent rocks cascading onto his foe.

As Kota watched in horror and awe, the tremor sent him tumbling toward the cliff’s edge. Just as he was about to fall, Humungousaur caught him by the shirt, shielding him as they slid down to safety. Once the rockslide was over, Humungousaur uncurled himself, making sure Kota was unharmed. 

Humungousaur: Sorry... for blasting you away too...

Kota: T-T-Thank yo-!

His voice faltered when he noticed Humungousaur’s battered form, cuts and bruises marring his body.

"Why? Why is he going this far?"

Before he could process it, Muscular clawed his way out from beneath the rubble. Humungousaur wasted no time, leaping into the air and slamming his full weight down on Muscular’s face, sending his fake eye flying from its socket. He stood over the villain, who was seemingly defeated. 

Humoungousaur: Face it pal, you're no match for Humungousaur.

Muscular chuckled, unfazed.

Muscular: Maybe not like this, but if you get to change shape, who says I can't?

He pulled out a syringe, injecting himself with an ominous glowing serum. His body twisted and morphed, growing more and more monstrous. His frame swelled into something disturbingly familiar—a warped Tetramand with green skin and loose tendons, raveling and unraveling around him. 

Humungousaur: What the?!

Omnitrix: Warning. Severe genetic damage detected.

Humungousaur: You're tellin' me!

Muscular: Hahahaha! This upgrade is AWESOME!!!

With monstrous strength, he slammed his fist into the ground, sending a shockwave through the terrain. Humungousaur dodged but was met with a relentless onslaught, but the villain’s massive form and reinforced hide shrugged off his attacks. Muscular seized Humungousaur’s head, slamming him into the ground before hurling him into the cliffside, leaving a massive crater. Humungousaur struggled to rise.

Humungousaur: *panting* Is that all you've got?

Suddenly, grotesque fifth arm sprouted from Muscular’s shoulder.

Humungousaur: Me and my big mouth.

The monstrous limb struck with crushing force, sending Humungousaur flying. Muscular grabbed his tail, repeatedly smashing him into the ground before hurling him against the cliffside, burying him under a mountain of rubble. 

Humungousaur: Ugh...

The dust settled, revealing Izuku—no longer Humungousaur—weak and battered. Muscular loomed over him, menacingly.

Muscular: Hahaha! This new form rocks! And it's all thanks to those monsters in your little watch!

Izuku tried to get up again, but Muscular kicked him back down, muscles surging as he prepared to finish him. Before he could strike, a rock hit his head.

Muscular: Huh?

Kota stood defiant, fists clenched.

Kota: Water Hose... papa... mama... Did you torment them like that too, before you killed them?!

Izuku: Kota...

Muscular: Huh? Oh I get it! This must be fate! Your their kid! Water Hose... its thanks to them that I've got this fake eye now.

Muscular smirked as Kota trembled, his rage boiling over.

Kota: It's your fault... It's because of guys like you that it always, always turns out this way!!!

Muscular: You kids are always shifting the blame. It's not like I had a grudge against them, I just wanted to kill and those two were in my way. It was a result of all our choices, of doing what we all wanted! AND WHAT'S SO WRONG WITH THAT?!

Just as Muscular lunged, Izuku surged forward using Full Cowling to smash Muscular in the face, before grabbing Kota and sprinting away.

Izuku: *panting* C'mon. The camp isn't too far from here. Let's head back and-!

Kota: Behind you!

Izuku turned as a new threat—Crujo—rushed in, slashing at him. Izuku quickly blocked just as his claws raked across the Omnitrix, sending sparks flying. Both Izuku and Kota are knocked across the battlefield. Deku tried to get up when he heard a faint buzzing sound and saw the Omnitrix glowing and blinking yellow. Before they could recover, Muscular sprung back up from the fallen rocks with a thunderous roar. 

Izuku: OH C'MON!!!

Muscular: Heh. That was one mean punch, Deku. I'm impressed. If it wasn't for this upgraded body, that probably would've taken me out for good. But I'm done playing around, Deku. That form of yours was pretty tough, way tougher than me... but without that... YOU'RE JUST A KID!!!

Izuku: KOTA GRAB ON!

Muscular punched the ground hard, causing the ground to shake once more. Izuku and Kota barely dodged the attack and were sent tumbling. Izuku no longer had anymore energy left to fight. Weakened but unyielding, Izuku stood.

"That camp isn't too far from here, but I won't be able to get far without getting caught! C'mon! Don't get scared! You show him your vulnerable, you'll be dead in no time. I've got to fight and win! Right here, right now!"

Izuku: Kota, stay behind me, and on my signal, run like hell back to camp!

Kota: "When it hits?" Wait! Don't tell me you're attacking him again! That didn't work last time! And your arm is all busted up! We need to run!

Izuku: Don't argue with me!

Kota: -!

Lightning crackled around Izuku as the Omnitrix flashed green.

Izuku: It's okay! Everything's gonna be okay!

Muscular then approaches the two of them, appearing from the dust, preparing another attack.

Izuku: One for all... 100%!!!

Muscular: DEKUUUUUUUUUUU!!!

Izuku: DETROIT!!! SMAAAAAAAAAAAAAAAAASH!!!

The punch landed, but Muscular’s muscles overwhelmed the force. Izuku pushed with everything he had.

Muscular: What's wrong?! That was weaker than before!!!

Muscular keeps pushing down on Izuku, harder and harder toward the ground.
Izuku: Fine... it's... fine... YOU'RE NOT GETTING PAST ME!!! KOTA RUN!!! RUN!!!

Kota hesitated, tears streaming.

Kota: W-Why?!

Muscular: SHOW ME YOUR BLOOD!!!

Muscular pressed down with all his might, forcing Izuku deeper into the ground. Every muscle in Izuku’s body screamed in protest as he struggled to resist, but his strength was failing. The Omnitrix was out of reach, and his vision blurred. This was it. The end.

Izuku: Mom... All Might... Ochako... I'm sorry... please forgive me... I love all of you...

Muscular: I'M GONNA CRUSH YOU! HAHAHAHA!!!

As Muscular bore down on him, suddenly, a stream of water splashed against Muscular’s side.

Muscular: Huh? Water?

He turned to see Kota standing with trembling hands, water dripping from his fingertips.

Kota: St-Stop it!!!

Izuku’s eyes shot open. Energy surged through his battered body.

Izuku: Kota!

Muscular: Later kid! I'll kill you later!

Izuku: Get away from him...

Muscular: Huh?

Izuku: Get away from him!

Electricity crackled around Izuku, his body vibrating with renewed energy. The Omnitrix’s dial spun wildly.

Muscular: Huh? What's happening?! How are you getting stronger?

Izuku gritted his teeth, pushing back against Muscular’s force. Kota watched in awe as Izuku slowly rose from the crater, green lightning arcing off his body.

Izuku: As if I'd let you lay a hand on him!!!

With a roar, Izuku shoved Muscular back. The Omnitrix surged with unprecedented power, transforming into the Ultimatrix once again. 

"Ultimatrix must protect Izuku Midoriya."

Izuku looked down at the device, recalling Melissa Shield’s words.

"This little upgrade utilizes both One For All and the watch's own power. Should come in handy if you ever get into really big trouble."

Izuku smirked as he stared down the mutated villain.

Izuku: Oh, you're in trouble now. The new rig comes with some extras. Now there's a time to go hero... and there's a time to go Ultimate!

Music Insert:

He slammed down on the Ultimatrix, engulfed in a brilliant green flash. His body expanded, morphing into Humungousaur—but the transformation didn’t stop there. Metallic spikes jutted out from the armored shell on his back. His skin darkened to a deep green, armored plating covering his torso and limbs. A spiked wrecking ball tail extended behind him, swaying menacingly. Izuku has just achieved an Ultimate Form.

"ULTIMATE HUMUNGOUSAUR!!!"

Muscular hesitated, unnerved but determined as he charged toward the hyper-evolved Vaxisaurian. 

Muscular: I don't care what kind of cheap tricks you pull! You're not gonna—

Before he could finish, Ult. Humungousaur backhanded him with titanic force, sending the villain crashing through trees and into the dirt, leaving a massive crater. The Vaxisaurian smirks as he cracks his knuckles.

Ult. Humungousaur: You were saying?

Kota watched, wide-eyed, as the battlefield shook with every impact. Trees splintered and rocks shattered under the sheer power of the combatants. Ult. Humungousaur's tail lashed out, catching Muscular off guard and sending him crashing into a boulder. The villain quickly recovered, his four arms grabbing chunks of debris and hurling them with deadly precision, but Ult. Humungousaur countered the attack, morphing his hands into cannons and firing several spike missles at the incoming debris.

Before giving Muscular another chance to attack, the evolved Vaxisaurian jumped up and slams the ground with his wrecking ball tail, causing a massive shockwave that stunned the villain and left him open. He charged, delivering a devastating barrage of smashes powered by Full Cowling. Muscular attempted to retaliate, swinging wildly, but his strikes barely phased the armored titan.

Muscular: HAHAHA!!! WELL AIN'T THIS A SURPRISE! YOU'RE NOT SO WEAK THEN!!!

Muscular slid back and forced all of his muscles into one gigantic arm.

Muscular: THINK YOU CAN STOP THIS?! JUST TRY ME DEKU!!!

He swung with all his might—but Ult. Humungousaur caught the massive fist effortlessly. With a single twist, he tore through Muscular’s overgrown tendons, eliciting a pained scream.

Muscular: ARGH!!!

Ult. Humungousaur reared back his own massive fist.

Ult. Humungousaur: Not impressed.

The Vaxisaurian then threw a thunderous uppercut launched Muscular skyward. As the villain struggled to recover, Ult. Humungousaur leapt after him, shifting his arms back into missile launchers and unleashing a relentless storm of spike missiles, at Muscular's hide, blowing him up and tearing his external muscle fibers.

The villain flailed, desperate to regenerate, but Ult. Humungousaur tackled him midair, slashing apart the exposed muscle fibers with his claws before kicking him back down. Muscular hit the earth hard, coughing up blood. Dazed but defiant, he tried to get back up, only for Ult. Humungousaur to spin midair, his wrecking ball tail crashing down onto Muscular’s skull.

Ult. Humungousaur: HYAAAAAAH!!!

Muscular’s body crumpled against the cliffside, barely conscious. As the dust settled, Ult. Humungousaur landed before him, the glow of the Ultimatrix still flickering bright. Izuku stood tall, still crackling with One For All’s energy. He clenched his fists, readying one final strike as the air vibrated with raw power.

Izuku: ONE FOR ALL... 10,000,000%!!! DELAWARE... DETROIT!!! SMAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAASH!!!

His fist collided with Muscular’s chest, detonating like a bomb. The villain rocketed backward, smashing into the cliffside as an avalanche of rocks buried him, finally rendering him KO'd. Upon his defeat, Deku let out a gutteral roar of victory, as Kota, overwhelmed, stared at his savior. He thenremembered his aunt's words.

Kota looks over at Izuku in total awe, remembering something Mandalay once said to him.

Kota… about your mommy and daddy… Water Hose… It's true that they left you behind. But because of them, countless lives were saved. I'm sure someday you'll meet someone, and then you'll understand. 

Tears welled in Kota’s eyes.

"Even though you don’t know anything about me… why did you go so far?"

Mandalay’s voice echoed in his mind.

Mandalay: Someone who will risk their life to save you… Someone who will be…

Kota wiped his eyes, looking at Izuku with newfound admiration.

Kota: …My hero. 

Chapter Text

Izuku exhaled sharply, his arms trembling and streaked with blood. The Ultimatrix beeped weakly, its glow fading from green to an ominous red before powering down.

Izuku: Phew... Thank you, Melissa Shield...

But as he examined the device more closely, sparks flickered across its surface, and wisps of smoke curled from the edges.

Izuku: Guess I pushed it too hard... Gotta be more careful next time.

With what little energy remained in the Omnitrix, he attempted to repair the genetic strain on Muscular. Reaching down, he retrieved the vial the villain had injected himself with earlier.

Izuku: This could be important evidence.

The adrenaline from his battle with Muscular was wearing off, leaving exhaustion creeping into his limbs. But his mind remained sharp. He glanced toward the trees, seeing that Crujo had vanished.

Izuku: And it looks like Crujo got away. He's still gotta be around here somewhere.

A quiet sniffle drew his attention. Kota stood nearby, wiping at his eyes.

Izuku: Kota! Oh my gosh, are you okay?

Kota: *sniff* Y-Yeah... I’m fine... Thank you.

Relieved, Izuku nodded and placed a reassuring hand on Kota’s shoulder.

Izuku: Alright. Let's get you back to camp.

They barely took a few steps before Kota suddenly hesitated, his eyes widening with concern.

Kota: M-Midoriya... are you feeling okay?

Izuku: Huh? What do you mean?

Kota’s expression darkened as he pointed. 

Kota: Your skin... it's turning gray. And your hands—!!

Izuku frowned and looked down. His breath hitched. His skin was indeed an unnatural shade of gray, his nails had elongated into sharp claws, and his ears—he reached up, feeling the pointed tips.

Izuku: Oh, great… just add this to the list. Now I’m turning into some freaky werewolf?

Kota: This isn’t one of your transformations?

Izuku: No. This has never happened before... Crujo bit me earlier. This must be his quirk.

Kota: What do we do?!

Izuku clenched his jaw, shaking off the panic rising in his chest.

Izuku: We don’t worry about me right now. We need to get back to camp. Mr. Aizawa should be able to—!

Before he could finish, a wave of unnatural blue flames erupted in the distance, swallowing part of the forest in a haunting glow. Izuku felt his stomach drop.

Izuku: Tonight is just not my night...

Suddenly, Mandalay’s voice rang in his head, clear and urgent.

"This is Mandalay.  We're under attack from the League of Villains and horde of Nomus. We're short handed without any other pros here so we're at a disadvantage. As of now, this is a code red emergency; you all have permission to fight back! Use your quirks as much as you can to defend yourselves and your classmates! If you can, run back to the campground. We'll do what we can do what we can here for now! Please! Stay safe!"

The message was clear. Izuku hoisted Kota onto his back and broke into a sprint. Elsewhere in the foreset, Bakugou and Todoroki were locked in battle with the monstrous werewolf. Bakugou hurled a massive explosion, but the beast dodged with unnatural speed. 

Bakugou: RGH! Stand still Fleabag!

Todoroki launched a wave of ice to freeze him in place, but Crujo retaliated with a powerful Sonic Howl, sending both boys skidding back. The force of the attack nearly overwhelmed them—until a second, equally powerful shockwave clashed against it, canceling it out. Todoroki’s eyes widened as the dust settled, revealing the source.

Todoroki: Wait... That’s—!

Bakugou: Oh, great. Another one?!

Emerging from the shadows was Izuku—but he looked different. Gray skin, fangs bared, claws out, and his eyes glowing an eerie green.

Todoroki:That’s Midoriya!

Bakugou: Shitty Deku?!

Izuku launched himself at Crujo, claws slashing and fists colliding. The two beasts clashed with primal ferocity, exchanging heavy blows, each trying to overpower the other.

Izuku: Remember me?!

The Yenaldooshi snarled and grabbed Izuku by the arm, slamming him into a tree. Pinning him down, he grinned, exposing his jagged fangs. Izuku didn’t hesitate and bit into Crujo’s arm. The werewolf let out a howl of pain, releasing his grip.

Izuku: How’s it feel to get bitten back?!

With a burst of Full Cowling, Izuku delivered a devastating kick, sending Crujo sliding back. His claws flexed. His body was still changing—more wolf-like by the second. Crujo roared and unleashed another Sonic Howl. Deku sucked in air and prepared to counter. 

Izuku: One For All—FULL HOWLING!!!

The two sound waves collided, shaking the trees and shattering the ground beneath them. Crujo staggered from the impact. Todoroki seized the moment, launching a powerful ice attack that encased Crujo in a solid block of ice.

Izuku: Nice one, Todoroki. That should hold him for a while.

Both of them looked at the wolf-boy in shock as his voice became more distorted.

Todoroki: Midoriya... What’s happening to you?

Bakugou: Yeah, what the hell?! Why do you look like a damn mutt? Is this another one of your stupid monster powers?!

Izuku: This is something else. Crujo’s quirk must’ve infected me when he bit me. But that’s not the worst part... The League is back. And they’re after both of us, Kacchan. 

Todoroki: Why would someone actively want to find Bakugou?

Bakugou: What's that supposed to mean, ya icyhot bastard?!

Izuku: Forget it! We need to get back to camp and help the others.

Bakugou: Tch. Like hell I'm teaming up with you again!

Izuku: Look, we stand a better chance of surviving if we stick together!

Bakugou: Don't care! Gimme some of that watch energy, and I'll take care of these villains myself!

Izuku: How about you start explaining how you're doing that in the first place?!

The two locked eyes, tension thick between them. It looked like they were about to come to blows when Todoroki stepped between them.

Todoroki: We don’t have time for this. The villains are hunting us down. If we don’t work together, we’re screwed.

Bakugou growled as he turned away.

Bakugou: Whatever. I can handle myself.

Izuku: Have you ever considered that not everything is about you?

Bakugou: You’re the one who said they’re after me. They wanna fight? I’ll give ‘em one!

Before anyone could stop him, Bakugou took off into the trees.

Izuku: Kacchan, wait! UGH! That dumbass!

Todoroki: Leave him to me. You go find the others. I'll track him down, and meet up with you later.

Meanwhile, the others were locked in battle, doing their best to hold off the monstrous enemy before them. Rex, Momo, Jiro, and Mineta stood together, facing a Nomu unlike any they had seen before. Its body was jagged and crystalline, resembling a Petrosapien.

Mineta: W-W-What is that thing?!

Yaoyorozu: It looks like another Nomu!

Mineta: Another one?! We barely took out the last one!

The Nomu roared, its crystalline arm shifting into a jagged blade before swinging at them. They barely dodged in time, the ground splitting where the blade struck.

Jiro: There's something weird about this one. It almost looks like Diamondhead!

Before anyone could react, a guttural growl echoed through the trees.

Mineta: W-W-What now?

A massive werewolf-like figure lunged from the shadows, unleashing a powerful Sonic Howl that blasted the Nomu back before pouncing on it. The others recoiled in shock as the creature turned to face them. Mineta and Jiro screamed in unison.

Mineta and Jiro: AAAAAAAAHHHHHH!!! IT'S THE YENALDOOSHI!!!

Izuku: No! It's me! IzukuuuUUUUUUUUUUUU!!!

Now in full wolf form, Izuku bore a striking resemblance to Crujo—green eyes, his shredded T-shirt and pants barely hanging on, and the Omnitrix now missing from his wrist.

Yaoyorozu: Midoriya?! What happened to you.

The Nomu screeched, already recovering from the attack and preparing to strike again.

Izuku: No time to explain! We need to take that thing out!

???: Oh I think you'll find that easier said than done!

They turned to see a gaunt man with green skin, wild white hair, and patchwork lab equipment strapped to his body. He sneered at them with a twisted grin.

Izuku: And who are you supposed to be?

Animo: I am Doctor Animo! Scientist extraordinaire! And this magnificent specimen… is all thanks to you, my friend. With your DNA, my pets have never been stronger!

Izuku: So it was you who unleashed those mutant Nomus in Hosu!

Animo: A field test of sorts, and a successful one at that I'd say! One step closer to reaching my goal of de-evolutionizing the world! Now, my pet DESTROY THEM!

The Nomu screeched, charging forward.

Izuku: Going XLR-wolf!

Izuku shouted, reaching for the Omnitrix—only to realize it was gone.

Izuku: Wait! It's not on my wrist!

There was no time to dwell on it. Izuku dodged the attack, slashing at the beast with his claws, but the damage was minimal. Yaoyorozu formed a sword and shield, striking at its crystalline hide, but barely left a scratch. Rex lunged in, swinging his massive blade, cleaving the Nomu’s arm clean off—only to watch it regenerate instantly.

Rex: Dangit! I hate the ones the regenerate!

Izuku: We don't have time for this! We've gotta end it now and get moving!

Jiro: Hey, Midoriya, I’ve got an idea! You know how opera singers can hit a high note and shatter glass?

Izuku: I see where you're headed! But we need a clear shot!

Rex: I'm on it!

Rex shouted, forming his Blaster Caster. He lashed out with energy whips, wrapping around the Nomu's neck, pulling it back, and holding it in place.

Izuku: Now!

Jiro plugged her jacks into the beast and amplified her sound waves. Izuku unleashed a Sonic Howl at full force. The combined sonic onslaught proved too much—the Nomu’s crystalline armor vibrated violently before shattering completely.

Animo: NOOOOOOO! My beautiful creation! Rgh! Curse you, Izuku Midoriya! Curse you and your medelling ways! I will have my revenge!

With that, he leapt away, disappearing into the forest. Izuku exhaled, shaking off the adrenaline.

Izuku: Alright... that was a thing...

Mineta: He's getting away!

Izuku: Let him go. We can't focus on him now. Our priority is making sure everyone is safe.

Jiro turned back to Izuku, raising an eyebrow. 

Jiro: Okay, but can we talk about the whole werewolf thing?

Izuku: It bit me when I was Swampfire, and now I've slowly been turning into it.

Mineta: If it bit you, doesn’t that mean it’s only a matter of time before you turn on us?!

Izuku: N-No! I'd never!

Yaoyorozu: Hang on a sec, I don't think we're dealing with a Yenaldooshi.

Izuku: But... it bit me. Isn't that why I'm like this?

Before anyone could answer, Izuku groaned, clutching his head. His body began to glow green, shifting as he grew taller, his shirt finally shredding apart. The Omnitrix symbol reappeared—this time embedded in his chest. Izuku has transformed into his Loboan form, Blitzwolfer. Jiro’s eyes widened.

Transformation Sequence: 

Jiro: Momo’s right. Maybe this isn’t some supernatural curse. Maybe your watch copied its DNA when it attacked you. That would explain why you’ve been stuck in monster mode.

Blitzwolfer: Which explains why the it isn't on my wrist anymore, but how'd I transform then?

Jiro: Did that thing ever touch the watch?

Blitzwolfer: Right! It scratched the watch with its claws… and it glowed yellow! 

Rex: So you can just copy forms on accident? That’s kinda cool."

The Loboan opened his mouth to respond—then his ears perked up. His expression shifted from curiosity to alarm.

Rex: What is it?

Blitzwolfer sniffed the air, eyes widening in horror. 

Blitzwolfer: I hear something… and I can smell blood. Not far from here.

He listened again. Then, a scream. A scream he recognized instantly.

Blitzwolfer: OCHAKO!!!

Chapter Text

While Izuku and the others were dealing with Dr. Animo and the Petrosapien Nomu, Ochako and Asui sprinted through the dense forest, still tracking Izuku's location through her power.

Ochako: C'mon, they're just up ahead I can feel it.

Before they could take another step, a gleaming blade whistled through the air. Ochako barely dodged, the knife grazing her leg.

Ochako: Ah!

Asui: Ochako!

A chilling giggle echoed through the trees as a shadow emerged from the bushes—Toga, grinning ear to ear, twin blades glinting in her grip.

Toga: There you are!!!

Ochako's instincts kicked in. She conjured a protective shield in front of herself and Asui before pushing Toga back with a forceful blast.

Asui: Her again ribbit...

Ochako: Stay the hell away from us!

The two stood firm, ready for battle, as Toga giggled menacingly. 

Toga: My name is Toga! You two are cute. Ochako... and Asui!

Ochako: Crap, she knows our names.

Asui: We're definitely at a disadvantage here.

Ochako: Hey, gimme a little credit! I just took down a witch!

Asui: With my help ribbit.

Toga examined her knife, pouting. 

Toga: *looking at her knife* Hmm... Not nearly enough blood. This machine should do the trick!

She pulled out a needle attached to a tube and lunged forward.

Ochako: I'm afraid of needles!

Asui reacted fast, wrapping her tongue around Ochako and yanking her out of the way.

Asui: Ochako! Run back to camp!

Ochako: I'm not leaving you behind!

She fired a volley of energy projectiles at the crazed villain. Toga dodged with erratic movements, weaving between the blasts. Asui leaped in with a kick.

Ochako: Tsu, look out!

Before Asui could react, Toga slipped past and raked her blade across her tongue, drawing blood.

Asui: Ah! Dangit...

Toga pounced, pinning Asui to the ground.

Toga: Tsu... Tsu! That's a cute nickname! I'm gonna call you that now!

Asui: Only my friends get to call me that!

Toga: Yay! That means we're friends now! You're bleeding a lot, and I LOVE blood.

Toga giggled, pressing the needle close to Asui's face.

Ochako: Stay away from her!

Ochako's eyes glowed pink as she fired an optic blast, knocking Toga off Asui. The villain tumbled but quickly recovered, brandishing two fresh blades. Ochako clenched her fists, as her energy swelled around them before they clashed. Toga slashed wildly, but Ochako was faster, weaving around every attack. With a well-timed counter, Ochako drove her energy-charged palm into Toga's gut, then drop-kicked her to the ground. Using a maneuver Gunhead had taught her, she pinned Toga down.

Ochako: Gotcha!

Asui: Nice one!

Toga grinned up at her, eyes gleaming with amusement.

Toga: Hehehe! Guess you got me!

Ochako: You're one weird villain, ya know that?

Toga: "Villain?" I just wanna live the way I want to. Is that so wrong?

Ochako: I'm gonna stop talking to you now. *to Asui* How're you holding up, Tsu?

Asui: Been better ribbit.

Ochako: We gotta find our way outta this forest and meet up with the others. Lemme try to read the area again.

She gripped her handkerchief, focusing on Deku's location.

Toga: Ochako...

Ochako: Whaddya want?

Toga: I can feel it... you and I... were the same... I can tell... there's someone you like isn't there?

Ochako: Huh?

Toga: And you wanna tell them. You wanna be with them more than anything, don't you?

Ochako's mind raced—memories of Izuku flooded in. Training together, fighting Vilgax and Malware side-by-side, laughing during late-night talks...

"Why is she telling me this? And how does she know anything about me?"

Her moment of hesitation cost her as Toga twisted free, flipping the situation.

Ochako: WOAH!!!

Asui: OCHAKO!

Toga threw a knife at Asui, lodging it in her leg before pinning Ochako down, her breath heavy with excitement. 

Ochako: TSU!!!

Toga: You're so cute Ochako. Your soft hair, you're bring brown doe eyes... I bet your blood tastes delicious...

She trailed a finger down Ochako's cheek, sending a shiver of revulsion through her.

Ochako: Get your hands off me, creep!

Toga: Hehehehe!!! I can't wait to see you dripping red! NOW BLEED FOR ME!!!

Toga giggled, raising her knife before a guttural growl cut through the air.

Blitzwolfer: GET AWAY FROM HER!!!

Toga turned as a massive, snarling creature leapt from the trees and knocked her away—Blitzwolfer.

Asui: Huh?!

Ochako: W-W-What the heck is that?!

Toga's eyes widened in delight, seeing Izuku in his new Loboan form.

Toga: OH! A PUPPY! ITS SO CUTE I WANNA STAB IT!!!

Asui: PUPPY?!

Blitzwolfer: Hey, are you alright?

Ochako: I... y-yeah... um...

She then notices the Omnitrix on his chest and realizes it's her friend.

Ochako: Deku?

Blitzwolfer: Yeah it's me. This is a new one.

Ochako: You're the Yenaldooshi?

Blitzwolfer: Why does everyone keep calling me that?

Asui: Behind you ribbit!

Toga lunged, launching needles two more needles at them. Blitzwolfer let out a sonic howl, blasting them back before slashing the tubes on her machine.

Toga: Hey! No fair!

Toga drew two more blades as Ochako lashed out with an energy lasso, yanking Toga away. Blitzwolfer stood over her, growling, as Ochako ruffled his fur.

Ochako: Good boy.

Blitzwolfer: Cut that out!

Toga didn't stay down long, flipping backwards and drawing another long blade.

Blitzwolfer: How many knives does one girl need?

Suddenly, the Omnitrix started beeping as Blitzwolfer flashed red and reverted back to Izuku.

Izuku: Oh man! Why are you timing out now?!

Toga gasped as she finally saw him in his normal form—her golden eyes widened, pupils dilating like a predator locking onto prey.

"It's him! It's the cute one!"

A wide, almost delirious smile spread across her face as she suddenly bolted toward them with frightening speed.

Asui: Heads up! She's coming back!

Toga: I'm Toga, Izuku!

Izuku: She knows me too?!

Before he could react, Toga pounced, knocking him to the ground. Her breath was ragged, a manic glint in her eyes as she held a knife above him.

Toga: You're so cool, but you'd be even cooler if you bled more, Izuku!

Her blade shot down, but before she could strike, a flash of pink light slammed into her side, sending her flying off of Izuku. She tumbled across the dirt, skidding to a stop.

Ochako: Get your hands OFF HIM!!!

She fired another round of energy blasts, forcing Toga to scramble out of the way. Dust settled as Ochako rushed to Izuku's side, eyes scanning him for any injuries.

Ochako: You alright? She didn't cut you, did she?

Izuku: Nah, I'm good. Pretty banged up already, though.

Ochako: *smirking* I noticed. Can't you ever go ten minutes without killing yourself, Doofus?

Izuku: *laughing* I'm sorry, Dweeb, but who just saved who again?

Before Ochako could shoot back, an eerie shift in the air made both of them freeze. Toga had risen to her feet. Her head was down, shoulders trembling, hands limp at her sides. The air around her felt... wrong. Then she whispered, her voice dangerously unhinged.

Toga: So that's how it is? Izuku...

Izuku: Eh?!

Ochako: What's she—?

Toga's head snapped up, her lips curling into a sharp grin, her eyes wide and wild.

Toga: Izuku... are you cheating on me already? And with my friend Ochako no less?!

Izuku: I... Did I... miss something? I don't-!

Before either of them could react, Toga yanked out two more knives and lunged, murder flashing in her eyes.

Toga: Anybody who stands between me and the ones I love is gonna pay!!!

Izuku panicked, furiously smacking the Omnitrix in rapid succession.

Izuku: Time in! Time in! Time in! Time in!

Before Toga's blade could reach them, a massive metal hand blocked her attack, forcing her back.

Rex: Sorry Chica, you're not touching those two!

Izuku: Rex!

A sudden sonic burst blasted through the air, striking Toga and making her stumble as Jiro skidded in before the two of them. 

Toga: Ngh!!!

Jiro: We've got this here! You guys get outta here and get Tsu to one of the pros!

Ochako: What about you? I can still fight!

Yaoyorozu: Tsu's injured, and Midoriya's out of power. Our priority is getting you to safety and finding Bakugou!

Midoriya: Okay, we'll find him. You guys be careful!

Ochako wasted no time, using her powers to lift Asui while Izuku ran alongside her.

Asui: Ribbit...

Ochako: Hang in there, Tsu! *to Izuku* So what's the gameplan now?

Izuku: Thinking... So far we've taken down at least 5 of the villains, but who knows how many more are coming after us?

Ochako: Can't be that many. Most of the small-time thugs from the USJ attack got locked up. We should take out as many as we can—knock 'em out one by one.

Izuku: Hold up! Look up there?

They both turned their gazes skyward. An orange glow flickered above the treetops, the sound of explosions echoing in the distance.

Izuku and Ochako: Bakugou.

Ochako immediately created a floating platform, lifting them high enough to see over the trees. From above, they could see the campsite—now a battlefield. The pros, their classmates, and Bakugou were locked in combat against another wave of villains. 

Ochako: Look! There he is!

Izuku's eyes locked onto something else—his stomach dropping.

Izuku: And another Nomu... never seen that alien before.

His eyes flicked to the Omnitrix on his wrist—still glowing red.

Izuku: Still needs time to recharge.

Ochako glanced at him, taking in the bruises and burns on his arms.

Ochako: Can you still fight?

Izuku clenched his fist, green lightning crackling around him.

Izuku: It'll have to do for now.

Ochako: Don't worry! We've fought these chumps before and won! We can beat them again!

She extended her fist. Izuku smirked and bumped it without hesitation. Together, they launched toward the battlefield.

On the ground, Aizawa, Vlad King, the Wildcats, and the students of Classes 1-A and 1-B fought desperately to hold their own against Dabi, Spinner, Shigaraki, and Animo's monstrous Nomu.

Mandalay: We can't keep this up much longer!

Shigaraki: Heh... Face it, heroes—you've already lost. That transforming brat should be dealt with by now. Now, tell me where I can find Katsuki Bakugou.

Bakugou: Oi! Lookin' for me Crusty?!

Bakugou rockets into the fight, launching himself high into the air, ready to blast Shigaraki. Before he can strike, a Nomu resembling Ripjaws surges forward, slamming him mid-air and sending him crashing into the dirt near Aizawa and the others.

Bakugou: Rgh. Dammit...

Aizawa: A Piscciss Volann?!

Shigaraki: Ah! There you are! We've been looking for you! So why don't you be a good little hero and come with us?

Bakugou grits his teeth, explosions crackling in his palms.

Bakugou: Not a fuckin' chance!

He and Todoroki charge at the Nomu, dodging its slashes and snapping jaws. Todoroki attempts to freeze it, while Bakugou blindsides it with a stun grenade. The Nomu, unfazed, slams its fists into the ground, creating a shockwave that sends both boys flying. As it lumbers toward Bakugou, a volley of pink energy blasts strikes its side. All eyes turn as Izuku and Ochako land before the villains in classic hero fashion.

Iida: They're back!

Todoroki: Midoriya and Uraraka!

Shigaraki: YOU!

Izuku: Hands off the idiot, Shigaraki!

Aizawa: Midoriya! Uraraka!

Shigaraki: Well well, The man of the hour! I was hoping Muscular would finish you, but then again, capturing both you and the bomber brat myself will be much more satisfying.

Izuku and Ochako stand side by side, energy surging around them, while Bakugou scowls. This was supposed to be his fight, and now Deku's here to steal the spotlight again. Shigaraki smirks as the Nomu and Dabi step up beside him.

Aizawa: You two take care of the Nomu, the rest of us will handle the league.

Iida: Prepare for battle 1-A!

Deku and Ochako both power up, their energies surging as the Nomu lets out a visceral roar and lunges at them. 

Izuku: You go high, I'll go low!

Ochako: Roger that!

The two them rush out of the way as the Nomu slams its fists into the ground. Izuku activates full cowling and uses his enhanced speed to run circles around the monster, while chipping away at it's legs. Ochako runs in the air using her energy platforms and hitting the Nomu with energy blasts and optic beams as the two of them push the monster back. The Nomu roars, snapping at them, but Ochako lands, forming a shield to hold it back. With the monster distracted, Izuku leaps in with a devastating uppercut.

Izuku: TEXAS SMAAAAAAAASH!!!

A shockwave ripples outward, knocking the Nomu back, but it lands on its feet, roaring again. It lunges for Izuku, but Ochako ensnares it with an energy tether.

Ochako: Oh no, you're not going anywhere!

Izuku smirks, cracking his knuckles before launching into a flurry of attacks. Bakugou, watching, grows more agitated.

Bakugou: Dammit! Those two idiots are NOT about to show me up right now! This is MY fight!

With a furious yell, he blasts himself forward, slamming into Izuku mid-attack.

Izuku: Kacchan! What're you-?! ARGH!!!

Deku is blasted away as Bakugou comes face to face with the Nomu once more, smirking and cracking his knuckles.

Bakugou: Big ugly is MINE!!!

The Nomu breaks free, snapping the energy tether and whipping Ochako away as it thrashes violently. Bakugou ignites his palms, grinning.

Bakugou: COME AND GET SOME, FISH FACE!!!

As Izuku regains his senses, the Omnitrix beeps, blinking green.

Izuku: About time!

With a confident grin, he slams the Omnitrix, transforming in a burst of green light. Meanwhile, Aizawa glares at Bakugou, recognizing the danger.

Aizawa: Bakugou! Back away now, that's an order!

Bakugou: This is MY fight! I'm taking this freak down myself!

Shigaraki watches with keen interest as the battle unfolds. Bakugou fights hard, but the Nomu's brute strength overwhelms him. It slashes his shirt, cutting into his chest. Just as it prepares to finish him off, a blast of high-pressure water knocks it away. Bakugou, sputtering, looks up—only to get drenched in another blast. He shakes it off and looks back to see Izuku in his Orishan form.

Waterhazard: Sorry Kacchan, but this guy is all washed up!

Waterhazard surges into battle, using his armored shell and enhanced strength to take on the Nomu. Bakugou scowls, once again shoved to the sidelines. Then, he notices Shigaraki watching idly, and an idea sparks.

"While Deku handles ol' Fish Freak... I can take down the big man himself. That'll show 'em who's boss!"

Bakugou smirks as he begins to ignite his hands, when Jiro, who's currently fighting off the real Shigaraki immediately realizes what's going on.

Jiro: BAKUGOU NO! IT'S A TRAP!!!

Bakugou doesn't listen, as blasts off high into the air and crash lands onto the villain with a Howitzer Impact, holding his hand to Shigaraki's face.

Bakugou: Move and I blast your face off!

Shigaraki: Hehehe... guess you got me!

As Shigaraki erupts into laughter, his form liquefies into a sludgy mass, slipping through Bakugou's fingers. A Twice clone. The real Shigaraki was never there.

Bakugou: W-What the hell?!

Suddenly, a voice crackles over Shigaraki's communicator.

Shigaraki: Now, Compress.

Before Bakugou can react, a small blue marble strikes his temple. In an instant, his body is pulled into it, vanishing without a trace.

Jiro: NO!!!

Aizawa: DAMMIT BAKUGOU!!!

Waterhazard: Kacchan?!

Waterhazard barely has time to process what happened before a Nomu's fist slams into him, sending him skidding across the battlefield. Mr. Compress twirls the marble between his fingers before tossing it to Shigaraki.

Mr. Compress: And that's one!

Shigaraki: Hehehe... one more to go!

Every villain turns toward Waterhazard, their eyes locked on their next target.

Waterhazard: Yeah, not happening.

Slamming his hand onto the Omnitrix, a burst of green light engulfs him. His form shifts, body hardening, limbs thickening.

"ARMODRILLO!!!"

Shigaraki: Bring me the boy!

The villains charge. Armodrillo drives his piston arms into the ground, unleashing a powerful shockwave that shakes the battlefield. Shigaraki leaps, grabbing onto one of the pistons. The moment his fingers make contact, decay spreads across the alien's armor.

Armodrillo: ARGH!!!

His arms already ached from overexerting One For All—now the searing pain of decay made it unbearable.

Shigaraki: Looks like you're beginning to come apart at the seams, hero!

Armodrillo grits his teeth, muscles straining, but Shigaraki's touch eats away at his defenses. Twice's clones swarm him, dragging him down. Dabi steps forward, his signature smirk widening as blue flames ignite in his palm.

Dabi: Nighty-night, hero.

He unleashes a torrent of fire, engulfing the dogpile in an inferno, only for the flames to spiral inward, vanishing into a swirling core.

Dabi: The hell? He should be roasting alive!!!

A fiery explosion erupts from the center, incinerating the clones. A new figure emerges from the blaze.

"SWAMPFIRE!!!"

The villains recoil as Swampfire stands tall, embers flickering from his shoulders. Only the Nomu remains unfazed, charging straight for him.

Swampfire: Everyone get back! I'll handle this!

The students retreat as Swampfire collides with the Nomu, fists meeting in rapid succession. He hurls fireballs, forcing the creature back, before surrounding it in a ring of fire in an attempt to contain the beast. 

Swampfire: Heh. Not so tough now, are ya?

The Nomu leaps high, clearing the flames with ease. Before Swampfire can react, it slams him into the dirt.

Swampfire: Huh. Guess you are...

Dabi: Shouldn't we keep attacking too?

Shigaraki: Look at him. They boy's tired. Muscular must have really done some damage. He's weak now. Let Animo's monster have it's fun. We'll take our prize when the time is right.

Dabi: If you say so.

Aizawa lashes out with his scarf, trying to restrain the Nomu, but the beast grabs the fabric and hurls him aside. Swampfire seizes the distraction, rooting himself into the ground and sprouting up behind the Nomu.

Swampfire: Peekaboo!

He delivers a crushing punch, sending the creature flying. Vines lash out, coiling around the Nomu and holding it firm.

Swampfire: *panting* Y'know... I am getting really tired of these Omnitrix copycats.

He unleashes another blast of fire, creating a blazing barrier between the Nomu and the heroes.

Swampfire: That should... hold 'em...

His knees buckle. Ochako and Iida rush to his side.

Iida: Midoriya!

Ochako: Deku, what's wrong?

Swampfire: *panting* I'm... running on fumes... need a sec... to catch my breath...

A monstrous screech cuts through the air. The Nomu barrels toward them, its claws poised to strike. Ochako throws up a shield, but each attack chips away at its strength.

Swampfire: *panting* You guys... need to get... outta here...

The Nomu screeches as it slams down once more, finally breaking the shield and sending them all flying back. Swampfire hits the ground and slides back, as his vision becomes fuzzy.

Swampfire: *panting* Ngh... c'mon... c'mon...

The final blow shatters the barrier, sending them all flying. Swampfire crashes hard, his vision blurring. He tries to raise his arm to conjure one last flame, but his body gives out. The Omnitrix flickers red, and in a final flash of light, he reverts to human.

Izuku: Go... hero...

Shigaraki grins as Compress seizes the moment, flicking another marble into the air. In an instant, Izuku vanishes.

Mr. Compress: And that's two for two, ladies and gentlemen!

Ochako: NO! DEKU!!!

Shigaraki: We have what we came for. *on coms* Kurogiri, take us home.

Dark portals rip open across the battlefield, swallowing villains and Nomu alike. Ochako's hands ignite with a searing pink glow as she fires a blast of heat vision, but the portal seals shut just as her beam strikes, missing its mark.

Everyone: MIDORIYA!!!

Aizawa: NO!!!

Ochako spots another portal forming and bolts toward it, desperation fueling every step, until a surge of blue flames slams into her, sending her sprawling.

Everyone: MIDORIYA!!!

Aizawa: NO!!!

Ochako: Nnh... Deku!

She hits the ground hard, struggling to get back up as the gateway closes and the portals vanish.

Ochako: NOOOOOOO!!!

She crashes hard, coughing as smoke rises around her. She tries to push herself up, but exhaustion pulls her down.

Ochako: Deku... no...

Silence falls over the battlefield. The students and teachers stare at the empty space where the portals once were, realization sinking in. The heroes had lost tonight. 

Chapter Text

Ochako's eyes flutter open, the sterile white ceiling of a hospital room swimming into view. Her body feels heavy, sore all over. She blinks, adjusting to the bright lights, before turning her head slightly. Beside her, Tsuyu lies unconscious, hooked up to an IV. Machines beep steadily in the background.

Ochako: Ugh... where... am I?

Iida: She's awake!

Mina: Oh my gosh! Are you okay?

Ochako: Guys?

Kirishima: You had us worried there, dude.

Kaminari: Yeah, that whole thing was nuts.

Ochako groans, rubbing her temples as a throbbing headache kicks in.

Ochako: My head is killing me... what happened? How long have I been out?

Jiro: 'Bout a day or so.

Ochako pushes herself up slightly, her heart rate picking up.

Ochako: Where's Deku?

Iida hesitates, his hands tightening into fists. Mina bites her lip, avoiding eye contact.

Iida: They... they got away. They got Midoriya and Bakugou

Ochako: THEY HAVE DEKU?!

Mina: Whoa, whoa, take it easy—!

Ochako: Don't tell me to take it easy, Mina! Those lunatics have my best bud!

The door swings open as All Might and Aizawa step inside, their expressions grave.

Iida: Oh! All Might! Mr. Aizawa! Uraraka just woke up.

All Might: Glad to see you awake Young Uraraka.

Ochako: How's Tsu?

Aizawa: The doctor's patched her up. She's gonna be alright, she just needs to rest for a while.

Kirishima: Sir, please tell us! How are the others doing?

Ochako: Please tell me Deku is okay.

Aizawa: The good news is for the most part, the rest of the students were largely unharmed. Other than Tsuyu and Yaoyorozu who sustained a slight head injury, everyone is okay. In regard to Midoriya and Bakugou, we're looking into finding them right now. I know you're probably concerned about Midoriya. However... this is strictly pro business. None of you are to get involved in any way.

Kaminari: What?!

Kirishima: Please sir, there's gotta be something we can do! They're our classmates.

Ochako: We can't just sit back and do nothing!

Aizawa: We've already lost two students. We don't want to risk losing anyone else. Like always, your safety is our top priority.

All Might: Excuse me kids, but could we have a moment alone with young Uraraka?

Iida: Of course! Class 1-A! Follow me!

Reluctantly, the class files out, leaving Ochako alone with the two pro heroes.

Ochako: So what's the plan? You guys have some kinda plumber tech to go and bust down the league's HQ?

Aizawa: No, the plan is we get you home safe so you can rest.

Ochako: What?! Mr. Aizawa c'mon!

Aizawa: Just because you're a plumber in training doesn't give you special treatment. You're my student and your safety is my top priority.

Ochako: I'm not going anywhere until I know Deku is okay.

All Might: Young Uraraka, please understand. We've already lost Bakugou as well as my pupil. I'm just as worried about him as you are.

Ochako: So let me help!

Aizawa: We're not risking any more students. We not only have to worry about Midoriya and Bakugou, but now the Omnitrix is at stake as well.

Ochako: C'mon, I've dealt with plumber stuff like this before! I helped you guys take down Vilgax, didn't I? And when Deku and All Might took down Malware, I was right there with them!

Aizawa: I'm not going to argue with you on this Uraraka. You're staying put. That's an order.

Ochako clenches her fists, staring at the blanket in frustration. All Might places a reassuring hand on her shoulder.

All Might: I know how much you care about him.

Ochako: He’s my best friend, All Might… I need to know he’s okay.

All Might: And I'm giving you my word that we will save him.

She meets his gaze, searching for any hesitation. There is none. Slowly, she nods. As the two pros leave, Ochako sits in silence for a moment, her mind racing. Then, her fingers tighten around the edge of the blanket. Carefully, she pulls out something hidden beneath her pillow—Charmcaster’s spellbook.

Ochako: If I'm gonna save Deku, then maybe this'll give me the edge I need.

Her eyes burn with determination as she flips through the pages, her grip tightening. She wasn’t just going to sit back and do nothing.

Elsewhere, Izuku groaned as he regained consciousness, his head throbbing like he’d been hit by a truck. His vision swam as his eyes adjusted to the dimly lit room, the scent of dust, alcohol, and something foul filling his nose.

Izuku: Ooooh, my head. What happened last night?

Twice: Oho! He's finally waking up! It's about time! Wakey wakey sleepyhead!

Izuku: Ugh... where am I?

Izuku forced himself to focus, his heartbeat quickening as he took in his surroundings. His arms were suspended above his head, bound by thick, metallic restraints. A heavy collar rested around his neck, cool against his skin. He turned his head to his left and felt dread pool in his stomach. Bakugou hung beside him, his expression caught somewhere between rage and exhaustion.

Izuku: K-Ka...cchan?

Bakugou: Rise and shine, asshole.

Izuku: Where are we?

A slow, deliberate clap echoed through the room, drawing their attention to the shadowy figure lounging in front of them. Shigaraki drawled, his crimson eyes gleaming with amusement.

Shigaraki: Welcome to our humble abode. Apologizes for the restraints gentlemen, but we can't have you two running off now.

Izuku immediately tried to activate his Omnitrix, twisting his wrist out of reflex. Nothing. He gritted his teeth and focused, attempting to summon even an ounce of his quirk. Still nothing.

Dabi: Don't bother. Don’t bother. Those fancy little cuffs of yours shut down your quirk. And you can't use yours without touching that watch.

Bakugou yanked at his bindings, his teeth bared.

Bakugou: You think this shitty trap's gonna hold me?!

Izuku: What do you want with us?

Toga: For starters, your phone number would be nice!

Shigaraki: Ignore her. What we have here is a rare opportunity. You two are powerhouses. And powerhouses like you deserve a chance to fight for the right cause.

Izuku and Bakugou said nothing, just watching him with wary, scrutinizing eyes. Shigaraki smirked and gestured toward a nearby screen. At the press of a button, the TV flickered to life, showing a breaking news report from a familiar channel. Izuku’s stomach clenched as he saw the headlines flashing across the screen:

"U.A. FAILS TO PROTECT STUDENTS! PUBLIC OUTRAGE MOUNTS!"

"IF OUR HEROES CAN'T KEEP CHILDREN SAFE, WHAT GOOD ARE THEY?"

"SOCIAL MEDIA ERUPTS: IS U.A. A FAILURE?"

Shigaraki chuckled, his voice oozing mock sympathy. 

Shigaraki: Well, isn’t that strange? The heroes are becoming the bad guys. The highest-ranking hero school on the planet, and they couldn’t even protect two students. Modern-day heroes sure have it rough, huh?

Izuku: And who's fault is that again?

Shigaraki: Blame is such a nasty thing. But look at how quickly people turn against the ones they once worshipped. It’s almost poetic, don’t you think? So much pressure to be perfect… so much criticism. But can you blame them? After all, a hero in this society only cares about money and glory. So much selfishness. That needs to change. Don't you think?

Bakugou: I think you should shut up before I shove my foot up your—!

Kurogiri: What we're fighting for is something greater. A truly just and free society. We intend to win, and we'd love to have someone like you two fighting by our side!

Izuku: Excuse me?

Shigaraki: So whaddya say? Will you join us and fight for a real cause?

The villains stiffened as Izuku and Bakugou erupted into laughter, their cackles bouncing off the walls of the rundown hideout.

Izuku and Bakugou: PFFT! HAHAHAHAHAHAHAHAHAHAHAHA!!!

Izuku: Y-You wanted us to j-join you?! The League of Losers?!

Twice: HEY!!!

Bakugou was laughing so hard his shoulders shook. 

Bakugou: As if I’d pal around with a bunch of morons like you! Go throw yourselves into traffic!

Toga: Now that's just rude!

Kurogiri: You dare mock the League of Villains?!

Izuku: *smirks* I'd mock anybody who says "mock" unironically.

Their laughter continued, the sheer absurdity of the situation fueling it. The League had expected resistance, maybe even fear, but this? This was outright mockery.

Izuku: I mean, imagine being so weak that you have to go kidnap a couple of kids just to give yourselves a fighting chance. That's pretty embarrassing.

Shigaraki: That's enough.

Bakugou: What kinda sicko attacks and kidnaps a bunch of kids in the first place?!

Izuku: Probably someone with a ton of deep-seated mommy issues, if we’re being honest."

Shigaraki’s eye twitched. 

Shigaraki: I said that's enough.

Bakugou: Nah, I’m just getting started. I'm gonna get outta here, and when I do, I'm gonna pound all of you shitheads into the ground with my bare hands, starting with you.

Shigaraki’s hands clenched into fists. His voice was ice cold. 

Shigaraki: I. SAID. THAT'S. ENOUGH."

A sharp click echoed in the room as he pressed a button on a small remote. White-hot agony exploded from their collars, sending jolts of electricity coursing through their bodies. Izuku and Bakugou gritted their teeth, muscles spasming as the shocks tore through them. They refused to scream. They wouldn’t give them the satisfaction. Izuku panted as the current finally stopped, his head sagging. 

Izuku: O-Okay... shutting up now...

Bakugou, still twitching, managed a smirk. 

Bakugou: W-Worth it...

Shigaraki exhaled, composing himself.

Shigaraki: These were not the results I was expecting. I have to say, I'm disappointed. No matter. You’ll see things our way soon enough. And if not… we have other uses for you. Doctor? We'll need you to remove the boy's support item. 

Izuku: Ha! Good luck gettin' it off my wrist!

A shadow loomed from the doorway, followed by the squeaking of wheels. A hunched, grinning figure stepped forward, adjusting his goggles.

Dr. Animo: Oh! I can't wait to study the both of you. Nyahahahaha!!!

Izuku and Bakugou exchanged a look, their stomachs sinking.

Back in the hospital, Ochako sat cross-legged on the bed, the spellbook floating before her as she flipped through its pages with her mind. Her eyes glowed faintly pink as she absorbed every word, determined to master its contents. Asui sat beside her, worried for her friend. The door creaked open, and a familiar voice called out.

Kirishima: Yo, Uraraka, you in here?

Startled, Ochako's concentration broke, and the book dropped into her lap. She blinked, her eyes returning to normal as she looked up to see Kirishima and Todoroki standing in the doorway.

Ochako: Oh hey guys. What's up?

Todoroki: We came to check up on you. How are you feeling?

Ochako sighed, running a hand through her hair.

Ochako: I've been better.

Kirishima: Still worried about Midoriya?

Ochako: Of course I am! He's my best bud, and now those villains have him. How could I not be worried?

Todoroki: Did Aizawa or All Might give you any leads of where they might be?

Ochako: No. They just told me not to get involved, same as you guys. Why?

Kirishima: We found him.

Kirishima glanced at Todoroki before pulling out a small tracking device. Ochako’s breath caught in her throat as she snatched the device, her grip tightening around it.

Todoroki: During the fight with the Nomu, Yaoyorozu created a tracking device just in case something like this happened. She gave one to the pros, but we convinced her to make one for us too.

Asui: Wait, what're you guys saying ribbit?

Before he could finish, Ochako swung her legs off the bed and stood, determination burning in her eyes. Without another word, she strode toward the door.

Todoroki: Uraraka?

Asui: Ochako, wait!

Kirishima: Dude, where are you going?

Ochako: I'm going to save Deku.

Her classmates exchanged glances, uncertain. Kirishima was the first to step forward.

Kirishima: I'm coming with!

Todoroki: Count me in too.

Asui: What?! Are you guys serious?

Ochako: My mind's made up, Tsu.

"Ochako Uraraka!"

They turned to see Iida marching toward them, his expression stern.

Iida: I know what you're thinking. Don't do it.

Ochako: Sorry Iida, but you're not talking me out of this.

Iida: No! I won't allow this! You're acting reckless! Making the same mistakes I did!

Ochako squared her shoulders and met his glare head-on. Suddenly, the rest of their class showed up, wondering what was going on. 

Shoji: You guys, what are you all doing out here?

Mineta: We having a party out here or something?

Mina: Ochako, what's going on?

Tokoyami: Wait... don't tell me you're doing what I think you're doing...

Todoroki: We're going after Midoriya and Bakugou.

Kirishima: We have to do this! Midoriya and Bakugou are our friends! We have to rescue them!

Everyone:...

Kirishima:... Okay, Midoriya's our friend, but Bakugou needs our help too.

Ochako: We can't just sit back and do nothing when they're in trouble.

Jiro: And you guys will be too if you try anything! Please, just think about this.

Todoroki: That doesn't matter right now. Whatever punishment follows we'll take it. Right now we've gotta do what we can to help our friends and the pros.

Jiro: But...

Asui: Listen, I know you guys are upset, but you're thinking with your feelings, not your heads. If you're breaking the rules, even if its for the right reasons... then doesn't that make you no different than a villain?

Ochako put her head down, deep in thought. She thought about all the times Deku had put himself in danger to save others, despite the risks. How he'd saved her life and so many others time and time again, even in the worst case scenarios. 

Ochako: Maybe… but if I were to just stand by and let my friend die, knowing I could have done something to stop it… what kind of hero would that make me?

Iida inhaled sharply, Deku’s words from their battle against Stain echoing in his mind.

"Meddling when you don't need to is the very essence of being a hero."

Ochako: I'm going to save Deku. And I won't let anybody stand in my way. If you're going to try and stop me... then this is your one shot.

Iida's resolve wavered before he sighed in defeat. The others stared in shock.

Iida: I supposed there's no stopping you. In that case... I'm coming with you.

Ochako: Iida...

Yaoyorozu: I made the tracker. That makes me just as responsible. I’ll go too..

Ochako: You guys... thank you.

Shoji: *sigh* There's no talking you out of this, is there?

Tokoyami: If that's the case then... the most we can do is wish you luck. Be careful out there.

Jiro: Just promise me you'll all come back safe.

Kirishima: We'll handle things from here. The rest of you guys stay safe and out of trouble. We'll take the rep from Eraser when we get back.

Tokoyami: We're with you in spirit.

Mineta: Good luck you guys, go kick some ass for us!

Todoroki: Alright. Let's get going. We've got a long way to go.

Ochako: Actually, I might have a way to get us there faster.

She pulled out the spellbook, flipping through its worn pages. Her eyes shimmered with pink energy as she focused.

Kirishima: Woah, where'd you get that?

Ochako: Picked it up from Charmcaster. Now if I do this right...

Her hands glowed, and a swirling vortex enveloped the group. In an instant, they materialized in the shadows of a run-down warehouse.

Iida: Woah, what on earth was that?!

Ochako: Teleportation spell. Slowly starting to get the hang of it.

Kirishima scanned the building as Todoroki checked the tracker.

Kirishima: Is this the place?

Todoroki: Looks like we're right on top of them.

Yaoyorozu: You sure? It just looks like some old warehouse to me.

Ochako: Lemme try something.

Ochako flipped through the book again. Placing two fingers to her temple, her eyes glowed as she scanned the building.

Ochako: There's definitely someone in there... or something.

Yaoyorou: It could be more Nomus, and we definitely don't wanna mess with anymore of those things.

Ochako: Alright, here's the plan. Me, Kiri, and Shoto will infiltrate the hideout, see what we can find out about their plans, and rescue the boys. Iida and Momo will be our lookouts.

Iida: If something goes wrong, you contact us immediately and get out, understood?

Ochako nodded, then cast the teleportation spell once more, whisking herself, Kirishima, and Todoroki inside the hideout.

Back in the lab, Dr. Animo had spent hours attempting to remove the Omnitrix. Dozens of tools lay broken and discarded, his patience wearing thin.

Dr. Animo: Okay. It's not coming off.

Izuku: Tried to tell you.

Dr. Animo: No matter. I can still extract all of the DNA I need.

He smirked, adjusting his goggles as he plugged a device into the Omnitrix. His fingers danced across his keyboard, initiating a scan.

Dr. Animo: Nyehehehe! All of that precious DNA will soon be mine!

Suddenly, an error flashed across the screen.

Computer: Access Denied.

Dr. Animo: Rgh! Useless hunk of junk!

He furiously typed more commands, desperately trying to breach the Omnitrix's firewalls.

Computer: Access Denied. Access Denied. Access Denied.

Dr. Animo: Going to need stronger equipment. I'll be right back. And just so you two don't get any ideas...

A loud croak echoed through the lab as a massive mutant frog with blood-red eyes and twisted horns hopped into view.

Dr. Animo: My pet will watch over you two! Mwahahahaha!!!

The creature glared menacingly at Izuku and his companion as Animo left the room.

Izuku: N-Nice... killer frog... thing.

Back in the hideout, Ochako and the boys maneuvered through dimly lit hallways. Twice clones patrolled the area, acting as sentries. Ochako used her magic to disable security cameras while Todoroki froze an approaching clone solid. The trio pressed on, using stealth to evade detection.

Ochako: Man, this place is much bigger on the inside.

Yaoyorozu: *on radio* See anything important?

Ochako: Yeah. You could say that.

The three reached a massive chamber—and froze. Before them stood rows of tanks filled with Nomus, some blank, others infused with alien DNA.

Iida: *on radio* What do you see?

Kirishima: More of those Nomus with Midoriya's forms.

Yaoyorozu: *on radio* More Nomus?! How many of those monsters are there?

Kirishima: Enough to make an entire army.

Ochako: That's why they wanted Deku. Their extracting his DNA from the watch to make their super Nomus.

Iida: *on radio* Uraraka, there's no way we can take on that many.

Ochako: Wasn't planning on it. As soon as this is over, we get outta here and let the pros know what we found.

A sudden noise from above drew their attention. Creeping forward, they spotted a gathering of villains—Shigaraki at the center, conversing with someone on a large screen.

Ochako: *whispering* There they are!

Kirishima: Alright Shoto, get ready to freeze 'em!

Ochako: Hold on, who is he talking to?

???: I want a status report on the boys, Tomura.

Shigaraki: We couldn’t remove the boy’s device, but Animo is extracting the DNA as we speak. You’ll love the results of his experiment, Master.

Ochako: "Master?"

???: The results I've seen from you so far have been very promising indeed. Willing or not, Izuku Midoriya will be a valuable asset to us. And what of the other one?

Shigaraki: Trying to recruit him for the league has been... troubling.

???: Hmmm... he is not a concern at this moment. Midoriya is our main focus. Your priority now is ensuring our army. Understood?

Shigaraki: I will not fail you, Master.

Kirishima: His master? Who's his master?

Ochako: I'm not sure, but whoever he is, that guy must be the big bad behind all of this.

Todoroki: There's something bigger going on. We need to be cautious.

Ochako: We need to get the guys and get out of here.

A voice suddenly shouted behind them.

Twice: Hey!

They whirled around, hands instinctively raised.

Twice: Who the heck are you guys?

Ochako: Uh... pizza delivery?

Before Twice could react, a loud knock echoed through the hideout.

"Pizza delivery!"

A beat of silence. Then, the door exploded inward as All Might barreled through, flanked by pro heroes.

All Might: WE ARE HERE!!!

Ochako: All Might?!

Chaos erupted. Gran Torino and the other pros surged forward, engaging the villains. Taking advantage of the distraction, Ochako swiftly incapacitated Twice as the clone melted into mud.

Kirishima: Guys, All Might and the pros just showed up!

Yaoyorozu: *on radio* Well don't just stand there! Get the boys and get outta there! Let them handle the rest.

Ochako: On it!

The trio sprinted toward the lab as the battle raged behind them. Time was running out. All the while, Izuku and Bakugou hung from their restraints, struggling in vain to break free. The dim, flickering lights of the warehouse cast long shadows, adding to the oppressive atmosphere.

Izuku: Never thought I was gonna go out like this. Hanging from the ceiling next to the guy who hates my guts the most while a killer frog tries to eat us. Well, I hope you're happy, Kacchan.

Bakugou: I don't wanna hear it, Deku!

Izuku: Oh you're gonna hear it, because it's your fault we're here in the first place!

Bakugou: How is this my fault?

Izuku: How is this your fault? How is this NOT your fault?! How is this NOT your fault?! Who charged in without a plan and got himself caught?! Another ingenius plan from the great Katsuki Bakugou!

Bakugou: And who the hell asked you to follow me, huh?! You could’ve stayed out of it!

Izuku: Oh yeah because you REALLY had a handle on things back there.

Bakugou: At least I didn't get turned into some freaky werewolf fucker and couldn't use my power half the time!

Izuku: Oh, excuse me! At least I didn’t walk straight into the most obvious trap in the world! Now we’re stuck, and no one knows where we are! Was that part of the master plan too?!

Bakugou: If you’re so damn smart, then figure out how to get us out of here!

Izuku scanned the room quickly, his eyes narrowing when he realized Bakugou was positioned close to his Omnitrix-wielding arm. He struggled, trying to free it, but his restraints held firm.

Izuku: If I can reach the watch I can get us both outta here. C'mon, swing towards me so you can grab it.

Bakugou: Ngh. Fine.

He twisted his body, forcing himself to swing closer. The first few attempts missed, his fingers barely grazing the Omnitrix.

Izuku: C'mon, c'mon!

Bakugou: Shut up, I'm trying!

After another strained effort, Bakugou finally latched onto the device.

Izuku: Yes! You got it! Alright, turn me into Humungousaur so I can bust us outta here!

Bakugou:...

Izuku: Kacchan?

Bakugou’s fingers tightened around the Omnitrix. His eyes darkened as memories surged through his mind—every moment he had been overshadowed, every time Deku had stood where he should have been. The little nerd who used to trail behind him like a lost puppy… now the strongest one in the class. Stronger than him.

"When we were kids he was nothing. Just another extra in my way... but now he's the most powerful kid in our class. He thinks he can 1-up me again. He thinks he's better than me. He's been hiding his powers all this time just waiting for the chance to show me up. Not anymore."

Izuku: Kacchan! Hit the watch!

Bakugou: No.

Izuku: Whaddya mean "no?!"

A sudden surge of energy crackled through the Omnitrix, sparking against Bakugou’s skin. Green lightning lashed out, attempting to repel him—but Bakugou endured it, his teeth bared against the pain. The glow shifted from emerald to an ominous orange, the energy flowing into him instead of into the device.

Izuku: Kacchan, what are you doing?!

Bakugou: I am SICK of being shown up by you. You think you can waltz in with your shiny new toy and cheat your way to the top? Not anymore, Deku!

Izuku: Are you seriously doing this now?!

Bakugou shouted, his voice cracking with raw emotion.

Bakugou: You always act like you’re so damn special! Like you’re better than me! Like you DESERVE all this power while I have to claw my way forward! I won’t let you outrun me again, Deku! I WON’T LET YOU WIN!

The Omnitrix wailed in protest, its energy surging wildly. Izuku fought against his restraints.

Izuku: Ngh! No! Don't do it, Kacchan!!!

But Bakugou didn’t listen. His body began to change, muscles bulging grotesquely as his skin turned a deep, pulsing red. His shirt ripped apart as his shoulders expanded, his breathing ragged and uneven. His bones cracked and stretched, warping into something monstrous.

Bakugou: YOU HAD ALL THAT POWER IN YOUR HANDS! NOW IT'S MY TURN!!!

Izuku: Kacchan! What the hell are you-! AAAAAAAAAAAAAHHHHHHHHH!!!

Izuku’s scream was drowned out by the whirring energy build up. The entire warehouse shook violently, walls crumbling as a blinding light engulfed the room. Animo burst in just in time to witness the chaos.

Animo: WHAT ARE YOU DOING?!

They ran inside just in time to witness the horrifying sight: Bakugou let out an agonized, guttural roar that echoed through the ruins of the warehouse as he continued to mutate. 

Ochako: DEKU!!!

Izuku: NGH! RUN!!!

They all watched as Bakugou's body morphed and contorted uncontrollably. He grew claws, an elongated tail, extra limbs, a third eye glowing with unnatural light. The Omni-energy continued to build between them as the ground shook. 

Ochako: GET BACK!!!

She quickly threw up an energy field as a massive energy blast erupted, tearing through the remains of the hideout and scattering heroes and villains in every direction. From across the street, Iida and Yaoyorozu watched in terror. 

Iida and Yaoyorozu: NO!!!

They both rushed over to the scene, only to see bodies lying all over the place as the explosion scattered everyone. The blast had decimated the Nomu Laboratory, all of them now lying lifeless on the ground. As the dust settled, Ochako hurriedly dropped the shield she had thrown up around herself, Todoroki, and Kirishima.

Ochako: Everyone alright?!

Todoroki: All clear here.

Kirishima: Look!

Lying amidst the rubble, battered and bruised, was Izuku.

Ochako: DEKU!!!

Ochako sprinted to his side, checking his vitals.

Ochako: Deku! Deku, say something! Are you okay?!

Deku slowly opened up his eyes, coughing weakly. 

Izuku: Kacchan… where’s Kacchan?

On the other side of the destroyed warehouse, Spinner stared at the devastation.

Spinner: What just happened?

Toga: There goes our hideout!

Suddenly, the ground rumbled. The remaining dust cloud churned as something massive moved within it. Everyone—hero and villain alike—froze in place, their gazes locked onto the shifting silhouette. The monster let out a low growl that shook everyone to their core. 

Ochako: W-W-W-What is that?!

Kirishima: It looks like some kinda freaky mashup of Midoriya's transformations.

Izuku: Wait a second...

The figure emerged, stepping into the broken moonlight. A hulking red beast, its skin rippling with raw power. Blonde tufts of hair still clung to its head, and its furious crimson eyes burned with a familiar rage. Izuku’s heart stopped.

Izuku: No! It... It can't be!

Kamui Woods and the other pros all took a step back. 

Kamui Woods: What is that thing?

Endeavor: It looks like another one of those monsters from Hosu.

All Might: Hold on, there's something different about this one.

Izuku swallowed hard. 

Izuku: It’s… Kacchan.

The creature tilted its head toward the sky—then unleashed an earth-shaking, primal roar that echoed across the entire city.

TO BE CONTINUED... 

Chapter Text

As the dust settled, Ochako hurriedly dropped the shield she had thrown up around herself, Todoroki, and Kirishima.

Ochako: Everyone alright?!

Todoroki: All clear here.

Kirishima: Look!

Lying amidst the rubble, battered and bruised, was Izuku.

Ochako: DEKU!!!

Ochako sprinted to his side, checking his vitals.

Ochako: Deku! Deku, say something! Are you okay?!

Deku slowly opened up his eyes, coughing weakly. 

Izuku: Kacchan… where’s Kacchan?

On the other side of the destroyed warehouse, Spinner stared at the devastation.

Spinner: What just happened?

Toga: There goes our hideout!

Suddenly, the ground rumbled. The remaining dust cloud churned as something massive moved within it. Everyone—hero and villain alike—froze in place, their gazes locked onto the shifting silhouette. The monster let out a low growl that shook everyone to their core. 

Ochako: W-W-W-What is that?!

Kirishima: It looks like some kinda freaky mashup of Midoriya's transformations.

Izuku: Wait a second...

The figure emerged, stepping into the broken moonlight. A hulking red beast, its skin rippling with raw power. Blonde tufts of hair still clung to its head, and its furious crimson eyes burned with a familiar rage. Izuku’s heart stopped.

Izuku: No! It... It can't be!

Kamui Woods and the other pros all took a step back. 

Kamui Woods: What is that thing?

Endeavor: It looks like another one of those monsters from Hosu.

All Might: Hold on, there's something different about this one.

Izuku swallowed hard. 

Izuku: It’s… Kacchan.

The creature tilted its head toward the sky—then unleashed an earth-shaking, primal roar that echoed across the entire city.

Everyone looked at the alien amalgam in absolute terror.  The monster looks down at its hands, then it finds a piece of glass and sees its reflection. It then glares at Izuku menacingly.

Bakugou: What did you do?

Everyone looks at Bakugou in horror. Izuku is speechless as he looks at his now mutated rival. 

Bakugou: WHAT DID YOU DO?!

Suddenly, Animo's frog emerges from the rubble and attacks Bakugou, but with his now monstrous strength, he knocks it away in one hit. Izuku is frozen in shock at what stands before him. Bakugou desperately tries to shut down the power like he's done before, holding his head in pain, but his body won't allow it.

Music Insert:

Bakugou: RGH! Ngh! No! I'm stuck like this! LOOK AT WHAT YOU'VE DONE!!!

Bakugou then rushes towards Izuku, who panics before using Full Cowling to dodge out of the way. He growls at Izuku with venom in his voice. 

Bakugou: THIS IS ALL YOUR FAULT!!!

Izuku: What?! How is this my fault?!

Bakugou: IT WAS YOUR STUPID WATCH AND YOUR STUPID ALIENS THAT TURNED ME INTO THIS! I'M A MONSTER NOW, BECAUSE OF YOU!!!

Bakugou outstretches his Diamondhead arm, firing shard projectiles at him, but Todoroki creates an ice wall to protect him.

Todoroki: Back off!

Izuku: YOU WERE THE ONE WHO ABSORBED ALL THAT ENERGY! I TRIED TO STOP YOU!!!

Bakugou: I don't give a damn! It's payback time, Deku!!!

Three green tongues shoot out from Bakugou's mouth towards Izuku, but he quickly dodges out of the way, before using full cowling to dash towards Bakugou.

Bakugou: THIS FOR ALL THE BULLSHIT I'VE HAD TO PUT UP WITH AT UA!!! EVERYTHING YOU PUT ME THROUGH!!!

Izuku: I put you through?!

Izuku grows more and more agitated as he dodges Bakugou's onslaught and races toward him. 

Izuku: One For All, One Hundred Percent! DETROIT SMASH!!!

Izuku lands a powerful smash attack on the mutant boy, knocking him back as he slides across the dirt, but Bakugou stands back up, shaking off the attack.

Izuku: He's still standing even at a hundred percent?!

Bakugou laughs menacingly as his eyes glow a burning red and he fires two neuroshocks from his eyes at Izuku. He braces for impact, when Iida runs in and grabs Izuku, saving him.

Izuku: T-Thanks, Iida...

Bakugou: Stay outta this! This is between me and Deku!

Iida: Bakugou please! You're not thinking straight! Just calm down!

Bakugou: I'M PERFECTLY CALM! DON'T TELL ME WHAT TO FUCKING DO, FOUR EYES, OR I'LL CRUSH YOU TOO!!!

Bakugou charges at them, but Ochako puts a shield up around them. Bakugou starts banging on the energy field when he's distracted with an energy blast to the head.

Ochako: Back off, ugly!

Bakugou: And you!!!

Bakugou sucks in air before breathing fire toward Ochako who puts another shield up and leaps out of the way, as Bakugou slams into the ground with his Vaxisaurian strength.

Bakugou: You tried to show me up too! All of you... All of you plotting against me... every one of you thinking you're better than me?! I'LL SHOW YOU!!! I'LL SHOW ALL OF YOU!!!

Bakugou goes wild, shooting flames and crystal projectiles from his arms. One of them grazes Ochako's leg and makes her falter. She hits the ground as Bakugou approaches, flying with his Necrofriggian wings, but Izuku in his Pyronite form leaps in the way to defend her, shooting flames at the mutant.

Heatblast: STAY AWAY FROM HER!!!

Bakugou growls, blocking the attack as he fires Big Chill's ice beam from his mouth, freezing the Pyronite before using XLR8's speed to rush in and send him flying with an uppercut. Heatblast goes crashing into the wall, leaving a huge burnt crater.

All Might: Young Midoriya!!!

Heatblast gets back up, but Bakugou doesn't let up, grabbing the Pyronite and throwing him high into the air, before hitting him with Jetray's neuroshocks. Bakugou the takes off once again and grabs the Pyronite, using Ampfibian's powers to electrocute him.

Heatblast: ARGH!!!

He struggles to break free as he desperately reaches for the Omnitrix before transforming in a flash of light and transforming into his Crystal Sapien form.

"CHROMASTONE!!!"

Chromastone fires a beam from his head crystal at Bakugou, hitting him in the face and causing him to drop the rock alien. Both of them hit the ground but Chromastone's still standing. He charges up his hands and fires another beam, but Bakugou lifts his shoulder, catching the energy blast with his own massive crystal.

Bakugou: Thanks for the snack, Deku!!!

Bakugou smirks as his stomach glows green and he fires Upchuck projectiles from his mouth. Chromastone runs across the field, tanking the explosive loogies, and powering up with Full Cowling. His crystals begin to glow green as lighting beings to shroud his body.

Chromastone: Alright, let's try this! Full Cowling, Chromastone style!!!

Chromastone winds his fist back and lands direct smash attack on Bakugou, creating a massive green shockwave then sends him flying. The Crystal Sapien doesn't let up, socking him left and right before firing a powerful laser beam from both his hands, using both his own power as well as the massive boost from One For All. Bakugou tries his best to push against the beam as he slams his arm on the ground and uses Armodrillo's power to make the it quake. 

Chromastone is thrown off his concentration and tries his best to stand his ground while vibrating rapidly, causing cracks to form in his body. He quickly hits the Omnitrix again and transforms into his Arachnachimp form.

"SPIDERMONKEY!!!"

He fires a web from his tail and zips over to Bakugou, using One For All to boost him and decks the mutated boy right in the face. Spidermonkey keeps webbing up Bakugou and chipping away at him as the boy grows enraged and tears through all of the webs.

Bakugou: GET OFF ME!!!

He rips through the webbing and bursts into flames, as he grabs Spidermonkey by the throat and pins him on the ground.

Spidermonkey: ACK!!!

Bakugou: WHO'S THE BIG SHOT HERO NOW?!

Spidermonkey: Y-You've... gotta... snap out of it... Kacchan!

Just then, he's hit with another energy blast from Ochako, whose eyes are burning pink.

Ochako: GET THE HELL AWAY FROM HIM YOU MONSTER!!!

Bakugou: Ngh! Stay out of my way, Round Face!!!

All Might then grabs Bakugou from behind trying to restrain him.

All Might: Young Bakugou! You're not thinking clearly! Stop this at once!

Bakugou: Hands off, Old Man!

He then uses Upgrade's power to shroud himself in green energy, shocking All Might causing him to release Bakugou. While he's distracted, Izuku uses the opportunity to transform again, turning into his Sonorosian form and duplicates himself.

"ECHO ECHO!!!"

The Echo Echos keep multiplying around Bakugou as he tries to take them out one by one.

Echo Echo: Wall... of... SOUND!!!

The Echo Echos let out an enormous sonic blasts, making Bakugou cover his ears in pain.

Bakugou: ARGH!!!

Everyone else in the area also covers their ears.

Toga: Things are getting messy real fast!

Compress: I suggest a strategic retreat!

Dabi: That's just running away dipshit.

Twice: Well unless you wanna fight THAT!

Shigaraki looks at the monster and knows they don't have a chance right now.

Shigaraki: Dammit. Fall back! Let's get moving, Kurogiri!

Kurogiri: Understood.

The villains then all retreat through a purple void. The pros try to stop them, but they're too late to reach them.

Endeavor: Get back here you scum!

Kamui Woods: We've got bigger problems to deal with!

The League of Villains sneaks away from the fight as the Echo Echos continue to scream. Bakugou grows angrier by the second, as he pounds the ground with one arm, using Swampfire's vines to capture and destroy several Echo Echo clones, before using XLR8's speed to rush toward the others and knock them out.

The remaining Echo Echo slides backwards as Bakugou glares at him. 

Echo Echo: Only got enough power for one more. Please don't give me Grey Matter. 

In one last ditch effort, Echo Echo hits the Omnitrix badge on his chest, transforming into his Vaxisaurian form.

"HUMUNGOUSAUR!!!"

Bakugou grins at the Vaxisaurian, welcoming the challenge.

Bakugou: Come and get me, big guy!

Humungousaur cracks his knuckles as he charges toward the mutant boy as they quickly enter close combat, exchanging massive blows. The Vaxisaurian whips him with his tail, before hitting him with a powerful haymaker, that sends him flying across the field. Humungousaur then stomps on the ground, causing it to rumble, and creating a fissure in Bakugou's direction. 

Bakugou reacts quickly enough, using XLR8's speed to evade the shockwave of the attack and circles around the dinosaur alien rapidly. Humungosaur is the larger of the two, but Bakugou is faster and still has Izuku's entire arsenal on his side. Bakugou shoots several fire balls and crystal projectiles at Humungousaur, before hitting him with a powerful crystal haymaker. Bakugou then takes to the skies, firing two beams from his eyes at the Vaxisaurian.

Humungousaur: ARGH!!!

Bakugou dives toward Humungousaur, but he smacks the mutant down into the ground as he goes tumbling. Humungousaur then charges at Bakugou, who puts up a large crystal shield to defend himself, before rushing around him with XLR8 speed to deliver another haymaker. Bakugou keeps up the speed, hitting Humungousaur rapidly with Tetramand and Vaxisaurian strength, before striking him with a huge fiery uppercut. He then takes off with his Necrofriggian wings, flying above Humungousaur, and outstretching his Heatblast arm as it begins to burn hotter.

Bakugou: THIS SHOULD BE A FAMILIAR MOVE DEKU!!

As Humungousaur soars upward toward the mutant boy, Bakugou lets out a massive Heatblast powered explosion that sends the Vaxisaurian downward, rendering him defeated. Izuku goes flying across the field and creates a large crater upon impact, before the Omnitrix times out and he reverts back to his human form.

Izuku: *weakly* Ngh... no... can't change back... now... 

Bakugou grins as he stands over his defeated rival, picking him up by his shirt collar.

Bakugou: Hehehe... I gotta admit, having all these quirks is a pretty sick side effect! Kinda ironic that it was your busted powers that got the better of you!

Izuku: *weakly* Kacchan... please...

Bakugou: And now you are gonna pay for all of the bullshit you put me through, DEKU!!!

Bakugou forms his Petrosapien arm into a blade, ready to finish it.

Ochako: NOOOOOO!!!

Iida: BAKUGOU DON'T DO IT!!!

Just before he can strike however, Bakugou is shot in the face with a powerful green energy blast, causing him to drop Izuku.

Bakugou: What the hell?!

He looks around to see a massive squadron of both humans and aliens in black and white uniforms, all holding weapons. There also some tanks present as well, all aimed at the mutant boy. One of the aliens grabs a megaphone and speaks to the mutant.

Gilhil: This is Magister Gilhil of the Plumbers! You are under arrest! Put your appendages in the air and get down on the ground now, or we will open fire!

Bakugou looks around, seeing that he is indeed completely surrounded.

Bakugou: You got lucky this time, Deku! Next time, you and me are gonna finish things.

As he says this he uses Big Chill's power to go intangible and phase through the ground to escape. Izuku is barely conscious at this point when he sees Bakugou get away.

Izuku: Ka...chan...

Ochako, Aizawa, and All Might run up to the boy as he falls unconcious.

Ochako: Deku! Deku, c'mon stay with us! Stay with us, Doofus!!!

His vision goes blurry and he can barely keep his eyes open before he blacks out.

After the incident, the League of Villains made their retreat to a reserve hideout unbeknownst to the heroes. Animo has gone off the grid, disassociating with the league, while everyone else is waiting and recovering while Shigaraki is in an office of sorts recounting the events with his master.

Shigaraki: I'm sorry, Master. Our plans have gone awry. We couldn't kill the Symbol of Peace or the transforming brat.

Sitting before Shigaraki is a man dressed all in black, sitting under an ominous light. His face is all mangled, scarred with no visible facial features. The man props his head up with his hand, letting out an eerie grin. This is Shigaraki's mentor and true big bad; All for One.

All for One: Now now, my pupil... there is nothing to apologize for.

Shigaraki: B-But Master-!

All for One: Losing the Nomus was indeed a significant blow, but more can always be created. And in addition, we gained something very VERY valuable.

All for One pulls up footage of Katsuki wreaking havoc on the heroes.

Shigaraki: The Bakugou boy?

All for One: Look at him. All that power. All that rage. He's stronger than any Nomu we've created before. It will undoubtedly bring about glorious destruction. The boy's... condition will most certainly cause the world to despise heroes even more. With him around, the heroes will have their hands full. 

Shigaraki watches Bakugou in action, his face a mix of awe, fear, and confusion. 

All for One: See how they tremble at his might, Tomura. The heroes have lost one of their own now. What are the heroes to do now? Kill the boy? Save him? Regardless of this outcome, society will be changed for ever. It's all so intriguing don't you think? And all we need do is lie and wait. 

Shigaraki considered his master's words before, focusing on his own mission.

Shigaraki: So what should we do now? Go after Midoriya while he's preoccupied?

All for One: Patience my child. We have all the time we'll need to figure out all those little details. For now, we can sit back and watch chaos unfold upon the world. 

All for One clicks a remote, turning up the volume on a news report covering the incident with Bakugou. He smiles with great interest in the boy's mutation

All for One: Hehehehe... if what I've been told is true, then not even that fool All Might will be able to stop him now. This is better than I could've hoped. Hero society will tear itself apart, and I don't even need to lift a finger. 

He then looks down at his pupil once more. 

All For One: Tomura, be a good boy and grab us some popcorn, will you?

Tomura silently nodded and walked off, though he was still unsure about all of this. Bakugou going mad wasn't the plan. And his master seemed so lax about the whole thing. Had they really done it? Would hero society destroy itself while he merely sat and watched it unfold? Had his master gotten overconfident in light of these events? Or was there something All For One wasn't telling him?

Despite everything, Shigaraki felt a pit in his stomach, an empty void, a hunger that hadn't been satisfied. 

"Midoriya. Regardless of what happens... you and I are going to settle things."

Several hours pass after the fight with Bakugou, as Deku finally begins to wake up, finding himself in the plumber's HQ in a hospital bed, with two Galvans tending to his wounds.

Driba: Look! He's waking up!

Blukig: No he's not.

Driba: Yes he is! Go get Eraser!

Izuku: Ugh...

Ochako: Deku! Oh my gosh!

She hugs her best friend tight, fearing she'd lost him a second time.

Ochako: I'm so glad you're okay.

All Might: How are you feeling, my boy?

Izuku: My head is spinning like crazy. What happened? Where's Kacchan?

Aizawa: Long gone.

Izuku: Mr. Aizawa!

Aizawa: And after careful analysis of what happened the other night, as well as your previous battles alongside the boy, I'm afraid what I've theorized is likely true.

Izuku: That being?

Aizawa: Bakugou is an Osmosian.

Ochako: "Osmosian"? Is this a quirk thing or an alien thing?

Aizawa: Osmosians are a race of beings with the power to absorb anything they touch, and replicate its properties. And it looks as if all this time, Bakugou has been absorbing the energy and DNA from the Omnitrix.

Izuku: So that's how he was able to mutate into all those half forms before.

Aizawa: Exactly. The trouble is, Osmosians can absorb pretty much any type of matter, living or non-living, but they can also absorb energy, such as the Omni-Energy that the watch generates.

Ochako: Why's that a problem?

Aizawa: Typically Osmosians, especially adolescents, tend to lose control when they absorb large quantities of energy, making them highly aggressive and unstable. And that combined with Bakugou's already extremely aggressive nature, makes him a massive threat to everyone. 

Izuku: So the Omnitrix is actually making Kacchan go crazy?!

Ochako: And now we have to worry about an insane Bakugou with all of your powers.

All Might: I'm afraid things only get worse from there, Young Midoriya.

Izuku: C'mon, worse?!

All Might: Young Uraraka reported that the League is working for someone bigger. That someone being my old nemesis... All For One.

Izuku: All For One? Wait as in-?!

All Might: Yes, the antithesis to our power, One For All. He's a villain unlike any other, one who thrives on chaos and destruction. His quirk allows him to steal other people's abilities and transfer them at will. It's why he became so feared over the years, amassing powers, creating an army of supervillains, all loyal to him. 

Izuku: The League of Villains?

All Might's face darkens as he recalls his history.

All Might: But his threat goes deeper than that. He's the man who took everything from me... My my mentor, Nana Shimura. She was a hero through and through, compassionate, fearless. She believed in the power of One For All to protect and uplift people.

Izuku listens intently, recognizing the name. Nana Shimura had been an enigma, someone he'd had heard about briefly but never in such detail. All Might continues, his voice heavy with emotion.

All Might: All For One didn't just want to break her body; he wanted to break her spirit. He targeted those she cared about, drove her into a corner... and in the end, she made the ultimate sacrifice. She gave her life to weaken him, but it wasn't enough. It was only a temporary victory.

Izuku: But... she was the wielder of One For All. How did he-?

All Might: All For One had amassed so many stolen quirks that not even her power was enough to fully stop him. She entrusted me with One For All, believing that I could do what she couldn't... defeat him for good.

Izuku can feel the weight of All Might's words pressing down on him. The image of the legendary Nana Shimura, a hero who stood against overwhelming odds, now shattered by the cruelty of one man.

All Might: I fought him once before, and that battle cost me almost everything. It left me in this state, weakened. 

All Might lifts his shirt, showing them his wound once more. 

Izuku: That's how... 

All Might: But even with him severely injured, All For One didn't vanish. He simply waited in the shadows, biding his time... and now, with the League working under him, it's clear he's making his move once again.

Izuku: So... All For One is behind everything... the League, the Nomu's, Kacchan's condition...

Ochako: But if they were stealing bits and pieces of Deku's alien DNA for their Nomus, does that mean... All For One wants the Omnitrix?

All Might: Precisely. If All For One gets his hands on the Omnitrix, he'd have access to an endless arsenal of powers... including Alien X. With that kind of power, he could end society as we know it. Young Bakugou is just the start. If All for One is involved, then I fear the worst is yet to come.

Ochako: *sarcastically* Perfect. So we have fight a psychotic alien super mutant and the strongest villain the world's ever seen.

Izuku: Then we better get going.

All Might: We?

Izuku: C'mon, let's start the Rust Bucket and-!

All Might puts a hand on Izuku's shoulder and stops him.

All Might: You're not ready.

Izuku: C'mon All Might! If this guy's as big of a threat as you say he is-!

All Might: BECAUSE he's such a big threat, I won't let you anywhere near him. You and your friends almost got killed the other night with your recklessness.

Izuku: But-!

Ochako: I'm sorry! I was just trying to help!

All Might: Midoriya, Uraraka... you've both got strong hearts. Some day you'll make great heroes... but as much as it pains me to say this... you're both grounded.

Izuku and Ochako: Grounded?!

All Might: Until I can trust that you kids aren't going to rush into danger trying to kill yourselves, no more hero stuff. You leave everything to the pros until I say otherwise, understood?

Izuku: But All Might-!

All Might: This isn't up for discussion. I can't risk seeing you kids get hurt anymore. We've already lost young Bakugou. I'm not losing you too... I'm sorry... but I'm benching you.

With that, All Might and Aizawa walk out of the room, leaving the two of them alone.

Music Insert:

Ochako:... so what now?

Izuku: I'll tell you what. We train.

Ochako: Train?

Deku looks at his best friend with complete seriousness.

Izuku: Kacchan is my responsibility. It's my DNA he's using, so I'm not gonna rest until I'm ready to face him again. AND take down All For One.

Ochako looks at her friend and nods, grabbing his hands.

Ochako: The neither will I! You've got the Ultimatrix, I've got my spellbook. If we absolutely dedicate ourselves to getting stronger, then those two won't stand a chance against us!

Izuku: I can't ask to you put your life on the line to help me stop Kacchan and All For One.

Ochako: You didn't need to ask me. I've already made up my mind. I'm with you Deku.

Izuku looks at his friend and smiles as they grab each other's hands.

Izuku: 'Til the end of the line?

Ochako: 'Til death do we part!

They both smile as they do their secret handshake, making a pact to themselves. They would stop All for One and bring back Bakugou, no matter what. 

Chapter Text

The sun shines, rising over UA High School early in the morning. Everyone else is home or asleep except for Izuku in his classic black and white T-shirt and Ochako wearing her tank top and gym uniform pants . Both of them know their mission now, still seeing the monstrous Bakugou in their minds. 

Music Insert:

Ochako: Ready to get to work?

Izuku: Let's get to it. 

Day 1:

Izuku launches himself forward, the ground cratering beneath him as One For All surges through his limbs. He hits the Omnitrix mid-air, turning into Four Arms as his massive red fists slam into boulders, reducing them to rubble. He focuses on utilizing Full Cowling while in alien form and maintaining balance and control. More rocks come tumbling toward him as he hits the watch and changes into Rath, using Full Cowling as he punches and slashes through the debris. 

Ochako hovers above him, flipping through her spell book with a fierce determination. She raises her hand, forming intricate glyphs in the air that send waves of telekinetic force, clearing debris. A flicker of pink energy pulses from her hands as she practices her newfound powers, focusing on control. She begins to learn and memorize certain spells to have them on command in a fight. 

Day 4:

The sound of fists hitting metal rings out as Izuku, as Chromastone, clashes with a towering steel structure they built for combat drills. Shards of crystal fly from his body as he reflects several energy blasts shot by Ochako from behind. He wants to be able to absorb and reflect energy without having to focus on the target directly. 

Ochako's mastery of her spell book is also advancing. She draws more glowing symbols in the air from memory, summoning barriers to block and retaliate against Jetray's Neuroshock attacks. She then fires a powerful energy wave to force him back before, gracefully dodging his strikes, creating more force fields to shield herself. Her movements are faster, her focus sharper.

Izuku is then seen in human form, charging up Full Cowling at 25% to break through a reinforced wall. His strength, focus, and precision has improved, each strike faster, more controlled. He breaks through several reinforced walls, each one more durable than the next but he's able to smash through them all with ease, gaining more and more control over Full Cowling

Day 7:

The two friends now move in perfect sync at incredible speeds. Izuku, as XLR8, blitzes across the battlefield, boosting himself with Full Cowling to gain more momentum. Ochako uses a spell to match his speed, riding the  wind currents of his movement as she hurls huge bursts of violet energy at him. XLR8 manges to dodge nearly every strike she throws at him before skidding across the pavement before her. They both train relentlessly, pushing each other harder every day.

Day 14:

In a forest clearing outside UA, Izuku and Ochako are sparring. Izuku transforms into Fourarms and starts throwing punches at his comrade, each fist charged by One For All. He swings left and right with incredible ferocity, but Ochako gracefully dodges everything as her pink aura flares up once more, enhancing her senses and agility. Her spell book is open and hovering by her side. 

She casts a defensive barrier just in time, the blow from Fourarms colliding with a shimmering force field and forcing him back. Her aura intensifies as she teleports in a flash of pink light, appearing behind him. She casts another spell, launching a several huge bolts of lightning at his back, but the Omnitrix beeps as Izuku switches to Feedback, absorbing the attack. They continue trading blows, neither holding back.

Day 21:

Sweat pours down Izuku's face as he powers up to Full Cowling 50%, pushing his body to its absolute limit. The green sparks of One For All swirl around him, but they're now mixed with the power of his aliens. Using Full Cowling, Deku super enhances the most powerful attributes of his aliens, taking notes on new powers and attributes he's learned about them over time, as well as how he could combat those powers in a fight. He runs through simulations in his mind, preparing for the inevitable fight against Bakugou.

Ochako begins to weave more complex spells from the book, all from memory, creating massive energy constructs that reflect her growing mastery of her new abilities. She's learned to combine her Gunhead Martial Arts with her magical powers, making her faster and more unpredictable.

As they train together, their bond grows stronger. They're perfectly in sync, knowing each other's moves before they happen.

Day 28:  

Standing across from each other in the middle of the field, both Deku and Ochako are ready.

Izuku powers up to Full Cowling 75%, combining it with Humungousaur's brute strength and XLR8's speed. His movements are fluid, faster than before, his control sharper, more precise. His transformations now perfectly in tune with Full Cowling, a true fusion of the both the Omnitrix and One For All.

Ochako's aura glows with intensity, her spell book flipping pages on its own as she channels more power into her attacks. She casts intricate spells while simultaneously using her martial arts training, moving with grace and precision as she weaves through Deku's attacks. They clash in a controlled spar, pushing each other to their limits but with smiles on their faces.

After a long day of training, Izuku and Ochako sit on the edge of a cliff, overlooking the city. Their clothes are torn up and they're both exhausted, but their spirits are high.

The scene then cuts to later that night in an alleyway somewhere in Kamino. Some rats are digging through the trash when they hear some footsteps approaching. Just then, Argit comes running by on all fours.

Argit: *panting* GANGWAY!!!

As he runs through the alleyway, he's shot at with a torrent of flames, that singe his quills. Argit pats out the flames and keeps running as he makes a sharp turn around a corner. The monstrous figure chasing him follows, leaving a trail of frost and ice behind him. Argit keeps running, knocking over trash cans and crates, trying to slow down his attacker.

Argit then ducks under a fence and hides on the other side, panting heavily. He looks around his surroundings, trying to stay quiet and hoping he'd lost the monster chasing him. To his dismay however, the fence begins to become covered in ice, as two massive hands rip it out of the ground. Argit tries to escape but the monster chasing him kicks him hard down the alleyway. Argit is about run again, but a large crystal grows out of the ground, trapping him with the monster.

Argit: W-W-Whaddya want from me?!

The monster stares at Argit with three piercing red eyes before stepping out of the shadows to reveal that its Bakugou. Argit looks in horror of the mutated boy standing before him.

Bakugou: Where is it?

Argit: W-Where's what? Y-You want some money or s-something? Look I-I'm not very liquid at the moment!

Argit pulls out his pockets revealing nothing but lint. Bakugou growls as he smacks Argit away before grabbing him with his Diamondhead arm.

Bakugou: Where's the weapon, Argit?

Argit: Ngh! L-L-Listen, pal! I don't know nothin' about you or any kinda weapon!

Bakugou: Maybe this'll jog your memory.

Bakugou reaches behind him and pulls out the destroyed device Argit has given him at the sports festival. Argit recognizes it, then looks at Bakugou again.

Bakugou: You owe me, Argit!

Argit: Katsuki! Buddy! Pal! Amigo! Y-You look different eh... you get a haircut? Hehehe...

Bakugou: No.

He drops the alien and kicks the destroyed device over to him again.

Bakugou: You promised me a weapon to take out Deku. Where is it?

Argit: L-L-Look, Katsuki, buddy, these things take time! And b-b-besides, you look pretty powered up yourself I mean... Phew! Look at ya? You been hittin the gym or...?

Bakugou: It's still not enough. I NEED that weapon!

He approaches Argit, sharpening his Rath claw. Argit backs away from him, slowly reaching into his back pocket.

Argit: Alright, alright, look! I don't got it on me now, but gimme a coupl'a days! I-!

Bakugou: Rgh! I'm sick of you giving me the runaround, rat!

Argit: Alright, ya want your weapon? HERE!!!

Argit pulls out a laser pistol and starts firing at the mutant boy, but the attack is futile as Bakugou stands before him unphased and angrier than before. Argit stands, clicking the now empty blaster, chucking nervously.

Argit: Hehehe... I know how this looks...

As Bakugou grows more enraged he ignites his Heatblast arm ready to wail on Argit, when a voice calls out to him.

"That's enough, Kacchan!"

The two of them look over to see Izuku standing before them with his arms crossed.

Argit: D-D-Deku?!

Bakugou: Hehehehe! Been a while, eh Deku? I missed pounding your stupid face into the ground.

Izuku: I can't let you hurt anyone else, Kacchan. Put him down.

Bakugou drops argit and turns his attention toward Izuku. Argit attempts to use this to escape, but Bakugou crystalizes his tail to the ground.

Bakugou: Don't get any ideas, rat. *to Izuku* Argit's mine... but I'll be happy to put you outta your misery first!

Bakugou roars at Izuku as he hits the Omnitrix transforming in a green flash of light.

"NRG!!!"

Bakugou dashes toward NRG with XLR8's speed, but he's blasted away as NRG shoots a power heated beam from his face plate. Bakugou crashes into a wall, even more enraged. Magma drips from NRG's face plate. Bakugou then uses his Upchuck tongues to eat some of the rubble around him and fire several explosive loogies at him.

NRG heats up his arms and blocks the attack, before rushing and Bakugou and punching him with heated fisticuffs. NRG then grabs Bakugou by the tail and tosses hims through the wall of an abandoned building.

NRG: This is between you and me.

Bakugou: Don't flatter yourself, Deku! Your time's coming!

Katsuki charges at NRG, who grabs him by the arm and throws him over before firing another energy beam at him. Bakugou blocks it with his Heatblast arm, but is blindsided by a powerful haymaker from NRG. He puts his hands together, charging up a massive orange energy ball, before firing it at Bakugou. The mutant boy dodges the attack, as the heated projectile hits a nearby lamppost, melting it.

Bakugou takes flight, charging at NRG again with his Wildmutt/Rath claw. NRG dodges the attack and fires another energy beam at Bakugou, but he uses Goop's power to make his body liquid and the beam goes through him. He then morphs around NRG and grabs him, crushing his armor with his enhanced strength.

Bakugou: I'm gonna crack you like an egg!

NRG: Let... go of me!

NRG then superheats his armor and releases his power in a short burst, forcing Bakugou off him. The amalgam stumbles backwards, growling at the armored alien. 

Bakugou: What do you even care if the possum gets hurt? He gave you shit just like everyone else!

Bakugou charges up Chromastone's energy in his crystal arm and fires at the two of them, but NRG steps in, blocking the attack.

NRG: I can't let you hurt anybody else. Let me help you!

Bakugou refuses to listen, turning up the power of the attack and overwhelming NRG with a bigger concentrated blast, knocking him backwards.

NRG: URK!

Bakugou: You need to cool off, Deku!!!

He takes in a deep breath and using Big Chill's power lets out a powerful ice beam, causing frost to form over NRG's suit, significantly dropping his body temperature. NRG tries to move but he's lost a lot of heat now. Bakugou then turns his attention toward Argit once more, grabbing him by the shirt.

Bakugou: I'd skin your ass alive here and now, but I'll give you one last chance. Send a message to your boss. Tell Valkanus he's got twenty-four hours to get me the weapon. Or else...

With that, he drops Argit and takes off, disappearing into the night sky. Argit looks into the sky, petrified when he hears NRG groaning as he tries to break the ice off of his armor. Finally, the Omnitrix starts beeping and flashing red as Izuku reverts back to human form. He gets back up, shivering while he looks around to find that Bakugou has fled the scene.

Izuku: Gone again.

Deku turns to leave and return to UA, when Argit jumps him in a fright. 

Argit: MIDORIYA!!!

Izuku: GAH! Argit?!

Argit: *shaking him* YA GOTTA SAVE ME MAN!!!

Izuku throws Argit off of him, as the alien grovels at his feet.

Argit: K-K-KATSUKI'S TRYNA KILL ME.

Izuku: Yeah, I noticed that. Wanna tell me why?

Argit: What're you nuts?! Out here in the open? Do you know how many people wanna use me a rug?

Izuku: I can only imagine. C'mon, follow me.

Argit: Aw gee, y-you're a real stand up guy Midoriya, y'know that! A real pal and a half!

Izuku walks off with Argit following him, sucking up to him the whole way. Finally the two reach UA and hop in an elevator heading down to the plumber base.

Izuku: This is it. Welcome to UA's Plumber base. 

Argit looks in awe at all of the alien tech surrounding him, as well as all of the potential cash in his pockets, when Izuku slaps a pair of energy cuffs around his wrists, knocking him out of his daydream.

Izuku: Just so you don't get any ideas.

Argit: You have some serious trust issues, y'know that?

Izuku just shrugs as he leads Argit through the base, while he mentally calculates how much all of this tech would be worth. Ochako can be seen, doing some sparring on a punching bag, practicing with her new powers and spells. She blasts the punching bag off its hook when she sees Deku walk in with Argit.

Ochako: Yo Deku!

Izuku: Hey!

Ochako: Whatcha got there?

Izuku: *slurps on his straw* A smoothie.

Ochako: I kinda meant the giant rat.

Argit: Hey!

Izuku: Ochako, this is—!

Thirteen: Argit!

The pro walks up to the three them, seeming upset to see Argit with them.

Argit: H-Hey, Thirteen! Long time no see, eh?

Thirteen: You're a slippery rat, aren't you?

Argit dramatically gasps and takes a step back at the alleged accusations being thrown at him.

Argit: I am appalled, Madam! I am but a humble businessman, trying to make a living in this cold cruel world.

Thirteen looks at the rat, unamused and seeing right through his act.

Argit: Look if this about that little "incident" on Khoros, I was simply repaying a debt I owed.

Thirteen: Right, you always owe somebody something, don't you? I have a right mind to throw you in a cell right now after that little stunt you pulled. 

Before Thirteen can throw Argit into a cell, Izuku steps in between them.

Izuku: Hang on, I didn't bring him here to arrest him. Kacchan was going after him. And Argit here is gonna tell us why.

The three of them turn toward Argit who sweats nervously, tugging at his collar.

Argit: Hehe... alright, alright fine. I may have... sorta... promised ol' Katsuki a weapon that could take out Midoriya. Ehehehe...

Thirteen looks at the boy with his arms folded.

Thirteen: Why am I not surprised?

Izuku: A weapon?

Argit: Look! I was in a bit of a corner, okay? I had to tell him something!

Flashback to after the Sports Festival. Bakugou and Argit have met up in abandoned garage somewhere in the city.

Argit: Katsuki, buddy, I've been waiting like an hour.

Bakugou drops the destroyed Power Amplifier at Argit's feet.

Bakugou: The power whatever-ifier didn't do jack shit!

Argit: Hmm... did ya try turning it on and off again?

Bakugou angrily smashes a nearby crate.

Argit: Hey! C'mon man, watch the merchandise!

Bakugou: Even my new powers aren't enough to put that asshole in his place. I'm tired of gettin' one upped by that nerd!

Argit: I dunno what to tell ya Katsuki. That power amplifier was your best chance.

Bakugou: Tch.

He starts to walks away.

Argit: Aw, why ya gotta be such a downer? After all we've been through! Ain't ya glad to see your old runnin' buddy?

Bakugou: C'mon, you know people! I know you do. You've gotta have something!

Argit: Hmmm... come to think of it, yeah, I think I got just the kinda tech your lookin' for. You're in the market for a specific premo-machino! And I got it!

Bakugou: For real?

Argit: Oh now you're listening! Now that I can do something for ya. You are so off my contacts list, man.

Bakugou: C'mon Argit, you've burned me on so many deals so many times, it makes me forget how tight we really are.

Argit looks at Bakugou angrily before smirking as the two fist bump

Argit: Aw, I can't stay mad at you old pal... not when there's money involved.

Bakugou: Alright, so let's see it.

Argit: Oh... I don't like... got it got it.

Bakugou: Aw c'mon, Argit!

Argit: BUT, I do have a connection to the guy who does. Just started working with this one guy. Dude's pretty well set up. Thing is, it's gonna cost ya.

The flashback ends and the scene shifts back to the plumber base.

Ochako: You gave Bakugou alien tech so he could beat Deku in the Sports Festival?!

Argit: Well obviously it didn't work, did it?!

Ochako: It does beg the question though; Bakugou's got all your powers, plus his explosions. As he is now, what kinda weapon would he even want?

Izuku: Honestly, I don't think it's about the weapon. The way his mental state's at now, I think he's holding a grudge for the sake of holding a grudge. 

Argit: Not sure how much my input matters here, but I think you're right.

As they're talking, Thirteen is inspect the now destroyed device Argit had sold to Bakugou during the Sports Festival.

Thirteen: You said this was a power amplifier? This is a Galvan Universal Translator.

Argit sweats nervously, scratching the back of his head.

Argit: Ehehehe... I was erm... low on supplies hehe...

Izuku: Y'know you were always kinda shady even in middle school. My mom told me I wasn't allowed to talk to you.

Thirteen: Good call.

Argit: Hey! If were done playing the blame game, there's a mutant monster on the lose that wants me hung and dried!

Aizawa: The rat's right.

Izuku: Mr. Aizawa?

Aizawa: We need to focus all of our attention on Bakugou. Over the past weeks, he's become a massive threat to everyone around him, and things are only getting worse.

He clicks a button, showing reports of Bakugou on a rampage, taking out both heroes and villains alike with no remorse.

"—And were on the scene with what appears to be a monster with multiple quirks! The creatures seems to resemble the same mutant creatures that rampaged in Hosu just a few months ago. Civilians are advised to vacate the area as the pros attempt to bring down this creature."

Aizawa: None of the pros have been able to defeat, restrain, or contain him.

Izuku: Don't worry, Sensei! I'm ready! I've been training with the Omnitrix and my quirk for weeks now! I'm ready to go after him again.

Aizawa: I know. And at this rate, you're his only hope now.

Izuku: ...what's that supposed to mean?

Aizawa: If Bakugou keeps this up for much longer, the pros will consider him too much of a threat to leave alive... they'll hunt him down.

Izuku: And do what, put him down?!

Aizawa: They'll try. And if the pros can't take him out, it'll fall into the plumbers' jurisdiction. There's already talk of sending him to the Null Void.

Ochako: The Null Void?!

Argit: *shudders* Not a fun place to be, I'll tell ya that.

Izuku: We've gotta stop him before that happens!

Argit: If you're goin after Kats, it might help to let you know he threatened to go after my supplier.

Thirteen: That being?

Argit: Guy calls himself Valkanus. Been running an illegal weapons operation on the outskirts of Kamino for months. Kats told me he wanted to send the guy a message. And he was willing to shoot the messenger to do it. He's gonna show up at his place tomorrow night to get his hands on some kinda weapon or trash the big boss.

Izuku: Alright, then we've got a plan.

Ochako: We do?

Izuku: We wait for Kacchan to show up, and raid Valkanus' hideout. Kill two birds with one stone!

Ochako: We're still talking about stopping Bakugou right? That's easier said than done.

Izuku: C'mon, this is what the two of us have been training for!

Aizawa: As much as I hate putting you kids on the field again, it is a good plan, and it's not like we have much choice.

Izuku: Works for me.

Argit: Woah, woah, woah! Time out! You're all talking about putting Valkanus outta business! More importantly, you'll put ME outta business. I'm risking my neck three ways now! I am a hardworking business man, and I for one am NOT in agreement with this plan.

Ochako: We could always tie you to a tree with a note that says "Fresh meat."

Argit:... y'know what? That job was gettin' old anyways.

Izuku smirks as the scene shifts to Valkanus' hideout. One of his minions walks up to him, bringing him a holo-projection disk.

Valkanus: What's this, now?

Pickaxe Minion: *alien language*

Valkanus takes the disk, as a hologram of Argit appears over it.

Argit: Hey big man!

Valkanus: Argit. I can't decide whether to trade with you or tear you to pieces.

Argit: I get that a lot.

Valkanus: Remember that counterfeit-isotope scam a few years back? You left me holding the bag and at the mercy of the Plumbers. Now I'm stuck on Earth, swapping level tech to get by... thanks to you!

Argit: C'mon that's ancient history! Water under the bridge!

Valkanus: What do you want?

Argit: It's not what I want, it's what you need from moi, 'cause what I've got is information. Information that could affect your business and my money!

Valkanus: I'm listening...

While Argit is making his "arrangements", Izuku is suiting up and getting ready for the mission. Suddenly, he hears a gentle knock at the door as All Might walks in, currently in his scrawny form.

All Might: I am here.

Izuku: Oh, All Might.

All Might: May I come in?

Izuku nods as All Might sits beside him.

All Might: You're going back out after Young Bakugou now?

Izuku: Yep. Got a lead on him. And this time, he's not gonna get away!

All Might: Young Midoriya... are you sure you're up to this mission?

Izuku looks down at the Omnitrix, then he looks up at All Might with new resolve.

Izuku: Yeah. I'm ready. I've done enough sitting on the sidelines. Kacchan's mutation is my fault. So I've gotta be the one to stop him... before anybody else gets hurt.

All Might: I know you and Young Bakugou have a history together, and not exactly a good one.

Izuku: Yeah...

All Might: I'm worried you're putting too much pressure on yourself, Young Midoriya.

Izuku thinks back to everything, fighting Muscular and the League, being kidnapped, and unintentionally unleashing the mutant Bakugou. Izuku manages to form a smile to reassure All Might.

Izuku: I'm okay! Really... this is just something I need to do, All Might.

As Izuku is about to leave, All Might stops him and gives him a hug.

All Might: Just be careful... and if you need anything, I am here.

Izuku smiles before heading out. All Might looks at his pupil in awe of how far Izuku has come, but still a bit worried for him. From there, Deku, Ochako and Argit make their way to an old abandoned air field. Several old war planes can be seen parked on the runway. Aizawa and Thirteen are waiting in reserve, ready to intervene if things go wrong. 

As the three of them walk into the hangar, they don't find anything out of the ordinary at first. No signs of a struggle or anything extraterestrial. 

Izuku: You sure this is the place?

Argit: Erm... place seems deserted. Maybe they... went out for a drink!

Ochako: Hey guys!

The three of them keep walking until they find hatch doors leading to a lower level that have been torn off the hinges.

Argit: Well, I brought you guys here just we agreed on. Good luck handling Kats!

Argit tries to walk away, but Ochako blocks him with a shield.

Izuku: You're not goin anywhere until we find Kacchan and Valkanus.

Argit: I was afraid you were gonna say that.

The three of them descend into the lower level, walking through a long tunnel before finding themselves in some kind of massive underground mine, filled with alien machinery and weaponry. KO'd pickaxe aliens are scattered all over the place, but there's no sign of Bakugou or Valkanus.

Izuku: Woah, this is way bigger on the inside. 

Ochako: They must have been digging for months. 

Argit: The guy must've struck a vain. *gulps* And it looks like Kats left us some bread crumbs.

Deku and Ochako look ahead seeing a trail of KO'd pickaxe aliens leading further into the cave. 

Izuku: Down the mine it is, then.

Argit shudders but reluctantly follows the heroes. As the three of them are navigating the tunnels, Valkanus waits at the heart of the mine, overseeing his minions digging up minerals and hauling them back and forth in hover carts.

Valkanus: Hehe, yeah! That's a good haul! Keep it coming fellas.

Suddenly, several pickaxe aliens come in running and screaming in their alien language, as they're attacked with torrents of flames, ice beams, massive vines, and crystal lasrs. At that moment, Bakugou bursts through the mine, finally coming face to face with Valkanus. The big boss Detrovite inspects the mutant boy before him with amused intrigue.

Bakugou: There you are!

Valkanus: And what are you supposed to be, some kinda walking art piece? BWAHAHAHA!!

Bakugou: Valkuns, I hear you've got something for me! Just the weapon I'm lookin' for!

Valkanus glares at the mutant boy, as his minions finish his armor's preparations. As he stands up, gears shift and components lock into place, making the final adjustments in his super armor. 

Music Insert:

Valkanus: Oh I've got something for you, alright.

The detrovite extands his mechanical arm which shifts into a humaungous energy cannon with several glowing, primed to fire.

Valkanus: Argit sends his regards.

He shoots Bakugou at point blank range, catching him off guard and sending the amalgam crashing through the tunnels. Bakugou snarls as he gets back up, his body smoking from the attack. Valkunus grins at the mutant before ordering his minions to charge. 

Valkanus: Take him down! But keep the body in tact, we could fetch a high price for this thing once its in pieces!

The Pickaxe aliens all ready their weapons, chattering in their native language as they surround Bakugou, who simply grins with eyes glowing red.

The scene quickly cuts back to Izuku, Ochako, and Argit making their way through the mineshaft, inspecting all of the glittering minerals and gems embedded in the walls around them.

Ochako: It's so sparkly. Kinda reminds me of Diamondhead. What is all of this stuff?

Argit: Taydenite. One of rarest and most valuable living gems in the Milky Way Galaxy. It's great for making a profit on its own, but a lotta folks use it for tools or weapons. Heck, this one guy I know made an entire car outta the stuff!

Izuku: I think I remember Aizawa saying something about this. It's a near indestructible mineral with a variety of different uses. Not only that, but it can also be used to power various machines and vehicles as well. It's extreme durability and versatility is what makes it so valuable to countless species across the galaxy. 

Argit: Bingo! And it looks like the big boss found a sweet spot and started diggin' here. 

Ochako: Guess he found the jackpot then.

Argit begins to pick up pieces of Taydenite as they're walking, stuffing as much as he can into his pockets.

Ochako: Maybe you should've brought a shopping cart. 

The three of them keep walking through the mine, but the tunnels seem endless and all look the same. 

Argit: You guys sure you know which way we're going? I swear we've passed that rock before. 

Izuku: Man, we're not getting anywhere like this. The place is a friggin maze!

Ochako: Let me try something.

She pulls out her spellbook and flips through the pages, as her eyes glow pink.

Ochako: Darkara Dorotien Aghosto!

As she shouts the incantation, a wave of pink energy shoots outward throughout the mine, reverbating through every single tunnel, before flowing back into Ochako.

Ochako: Got him! This way!

Izuku and Argit follow after Ochako as she leads them toward the heart of the mine. When they reach the clearing they find Bakugou absolutely decimating Valkanus' minions with a visceral roar. 

Izuku: There he is!

Bakugou snarls as he punches and slashes his way through Valkanus' minions, who are throwing everything they possibly can at him. However, their attacks are leaving Bakugou more annoyed than anything else. 

Bakugou: Ngh! Get OFF ME!!!

He throws one of the Pickaxe aliens into the horde before igniting his Heatblast are and shooting a humungous torrent of flames their way. He doens't let up, whipping them around with his Goop tendril, using the acid to melt through their weapons. Valkanus stands ready to intervene when he sees Izuku and the others at the cave entrance.

Valkanus: MORE intruders?! And Argit...

Argit: B-B-Boss, this ain't what it looks like!

Valkanus: I've got too many witnesses. Get rid of 'em!

The horde of minions chatter frantically in their native language as they aim their pickaxes and blasters at the three of them, trying to back them into a corner.

Argit: What now?!

Izuku: We take 'em down! How about a little Fourarms?

He quickly activates the Omnitrix and smacks it down, transforming instead into a Necrofriggian.

"BIG CHILL!!!"

Ochako: What happened to Fourarms?

Big Chill: I've got to get a manual for this thing. New plan.

He sucks in some air and uses his freeze breath to blow an icy wind toward the pickaxe aliens, causing them all to freeze up. 

More of them approach the trio as they begin to fight off the onslaught of Valkanus' minions. Big Chill phases through them, causing them to freeze up as Ochako blasts them away with her energy bolts and optic beams. Admist the chaos, Argit tries to find an opening to escape whilst dodging attacks from Valkanus' minions.

Argit: I've done my part. Time to get while the gettin' is good!

Ochako and Big Chill keep fighting, but the miners keep coming, armed with jetpacks and little mech suits. Valkanus' minions continue their onslaught, pressuring the heroes with their numbers. Ochako makes a shield to deflect the lasers, before taking out the mechs with a big energy wave. Big Chill combines his powers, using his cryokinesis and Full Cowling to take out as many pickaxe aliens as he can, forming his fists into icy maces. 

The tunnels continue to flood with miner aliens to an overwhelming degree.

Ochako: These guys just keep coming! Ngh!

Big Chill: I'm gonna try something, get to higher ground!

Ochako nods and forms a platform hovering in the air. Big Chill's eyes glow green as his hands become surrounding in an icy blue aura. The Necrofriggian then pounds his fist on the ground, freezing it up, leaving the incoming pickaxe aliens frozen solid. However, Argit was also caught in the attack, his feet are now stuck too the ground.

Argit: S-S-S-So c-c-c-cold...

Ochako: *panting* Maybe lead with that next time, Deku?

While this is going on, Bakugou is pounding his way through the pickaxe aliens, before closing in on their boss. However, Valkanus sees him coming and blindsides the amalgam with a power uppercut. Bakugou crashes into the wall of the mine, causing several shards of Taydenite to fall at his feet. 

Bakugou: Rrrrgh...

Valkanus approaches him menacingly, his armor readjusting itself, reforming his mega blaster from before in one arm, and a Taydenite drill on the other.

Valkanus: You shouldn't have stuck your nose in my business, kid. Now you're gonna pay for it.

The Detrovite takes Aim, but the Bakugou absorbs the weapon's energy with Chromastone's crystals before he can fire again. 

Bakugou: You sure about that one?!

His crystals crackle with energy before he fires a powerful explosive blast from his tail at Valkanus, forcing him back. Valkanus stumbles back, but stands his ground as he charges toward Bakugou once more.

The two behemoths then enter close combat, exchanging fisticuffs and energy blasts. Bakugou wails on Valkanus, shooting flames and firing neuroshocks, while slamming into him hitting with XLR8 speed punches. Despite this, the Detrovite's armor is able to tank everything he dishes out.

Valknus then retaliates, firing his blaster once more and winding back a haymaker with his drill arm. Bakugou blocks the attack, using his own Diamondhead arm to block the drill, as it begins to crack into his crystals. Bakugou then gets the upper hand, forcing the drill arm away from his own. In that moment he bites down on it, attempting to eat it and then fire it back with Upchuck's power. However, the drill and armor are too dense for him to chew through, causing him to groan in immense pain.

Bakugou: AAAARGH!!! What's that thing made off?!

Valkanus smirks at his foe, his armor still gleaming.

Valkanus: Taydenite. The rarest gem this side of the galaxy. Very profitable, and it just so happens to be completely indestructible. Valknus then spins the drill before slamming it into the ground, causing it to shake, and rubble to topple over Bakugou.

Bakugou: RGH!!! Dirty bastard!!!

He struggles to lift the rubble as Valkanus then walks up to Bakugou, believing his foe to be defeated.

Valkanus: Like I said, you shouldn't have interfered in my business, Katsuki Bakugou.

Bakugou's eyes widen as the Detrovite drops his full name.

Valkanus: That's right, Argit told me all about you, kid. You might be some kinda giant powerhouse freak show right now, but deep down you're just a scared little punk desperate for power over someone else. 

Valkanus revs his drill one final time and lunges at Bakugou, but he phases through both the drill and the rubble on top of him, going underground.

Valkanus: What the-?!

Bakugou: Hehehe...

Valkanus: Where are you?! Show yourself?

Just then, Valkanus feels a chill flow through his body, as his armor starts to freeze up. Bakugou uses Big Chill's powers to phase through the armor, causing it to freeze and lock up.

Valkanus: Hey! C-Cut that out! I'm f-f-freezing!

Bakugou: That's the idea!

Bakugou keeps phasing through the armor the armor, coating it in ice and effectively immobilizing the Detrovite in place.

Valkanus: Can't... move... so cold...

Bakugou then rises up from the ground in front of him, before forming a blade with his Diamondhead arm and slashing both of the arms off of the suit. The mutant boy smirks as he winds back his Vulpimancer arm and punches straight through the armors core, ripping out a massive chunk of Taydenite, acting as the power source. Valkanus' armor begins to sputter and crack as it falls apart, revealing Valkanus' true, infant-like body.

Valkanus: Hey! That armor was expensive you know! I don't come around to where you live and wreck your stuff!

Bakugou then picks up the now helpess Valkanus by the throat and lifts him into the air.

Valkanus: H-Hey! What're you—?!

Bakugou: If you don't have what I want, then I don't need you!

As Big Chill and Ochako are fighting off the remaining pickaxe aliens, he watches this happen before him.

Big Chill: NO!!!

Bakugou tightens his hold on Valkanus, about to end his life, when Big Chill phases out of the ground, hovering in the air before him. He uses his intangibility to free Valkanus from Bakugou's grip as he falls to the ground.

Big Chill: That's far enough Kacchan!

Bakugou: Outta my way, Deku!

Big Chill: He's done. You beat him, you won.

Bakugou: He's still breathing.

Big Chill: You need to listen to me, Kacchan. It's the power, your mutation! It's made you lose control! You're not well, please let me help you!

Bakugou: You just don't get it, do you Deku? I don't need to answer to anybody anymore! I've finally got the strength I deserve, and that terrifies you, because you're back where you started. Beneath me. Now move.

Big Chill doesn't budge.

Big Chill: You don't need to do this, Kacchan.

Bakugou: I don't... *his eyes glow a burning red*... but I want to!

He charges and fires a powerful neuroshock at Big Chill, catching him off guard, before grabbing him and using Ampfibian's power to electrocute him. Bakugou then throws the Necrofriggian hard into the wall of the cave as Big Chill hits the ground smoking.

Big Chill: Ugh...

Bakugou: Quit trying to be the big hero, Deku! You can't save me!

Big Chill's eyes glow brighter, as a familiar green lightning begins to spark from the Ultimatrix.

Big Chill: Then I guess.. You'll have to save... yourself...

Music Insert:

Big Chill twists the dial of the Ultimatrix and slams down on it again, as four metal spikes jut out from each side. A green light wraps around him, as Big Chill's body becomes buffer changing from blue to red. His wings grow larger and start burning at the edges. The flash of light catches Bakugou's attention as he turns around to see the hyper-evolved Necrofriggian.

"ULTIMATE BIG CHILL!!!"

Ult. Big Chill: Now it's just you, me, and fire so cold it BURNS.

Bakugou grows even more agitated and rushes at Big Chill, who fires a torrent of flames from his mouth the freeze up upon impact, leaving his Heatblast armor frozen solid.

Bakugou: Huh?!

Ult. Big Chill smirks as he decks Bakugou in the face with icy flaming fist that knocks him back into a wall. Bakugou gets back up, noticing a lot of frost on his body after the attack. He shakes it off and gets ready to fight again. Ult. Big Chill glares at him before taking a deep breath and shooting a blast of fire at Bakugou that freezes upon impact. Bakugou dodges the attack with XLR8's speed, as the wall behind him freezes up.

He rushes at the necrofriggian, punching and slashing with his claws, but Big Chill phases through it all, causing more and more frost to appear all over his body, making him much slower.

Bakugou: I DON'T CARE WHAT NEW TRICK YOU PULL! YOU THINK THAT TODOROKI SHIT IS GONNA SCARE ME?!

Bakugou begins sparking wildy with electricity before firing a thunderbolt from his crystal arm. Big Chill crosses his arms, forming an icy shield with his cryokinesis that creates an icy viel upon impact, giving Big Chill a smokescreen. Bakugou looks around, trying to find Big Chill in the mist.

Bakugou: COWARD! WHERE ARE YOU?!

Suddenly, Bakugou is socked in the face. Then again, and again.

Bakugou: SHOW YOURSELF, DAMMIT!!!

He keeps looking around while getting knocked around by Ult. Big Chill. Bakugou then uses Wildmutt's powers to detect Big Chill moving around him, smelling him through the mist. Ultimate Big Chill goes in for another attack, but Bakugou blocks and counters.

Bakugou: GOT YOU NOW!!!

He attempts to grab the Necrofriggian, but Ult. Big Chill goes intangible, vanishing in a torrent of flames that leaves Bakugou's arm frozen. 

Ult. Big Chill: Remember the time Todoroki did this?! 

He then appears behind the Amalgam and clenches his fist, increasing the temperatrue of the ice, but not it's state of matter. 

Bakugou: AAAAARGH!!! What the hell?!

Bakugou snarls as he shakes off the attack, cracking the superheated ice and swinging at Ult. Big Chill as they come to a stand off.  While this is going on, Valkanus is running as fast as his tiny feet will carry him, before hopping into one of his minions' mechs. 

Valkanus: This place is getting too noisy.

Valkanus quickly fiddles with the controls, activating a tiny escape pod and taking off through the cave. 

Ochako: Hey! He's trying to get away!

Ochako quickly rushes after him, past Argit, who's still trying to break free.

Argit: LITTLE HELP HERE!!!

Valkanus chuckles as he rockets through the mine, clicking a button on the mech that triggers several explosives lines through the cave. Ochako freezes as the mine begins to rumble violently.

Ochako: What're you doing?!

Valkanus: I've been mining here for months little lady. I've got more than enough taydenite to get me off this backwater world. So now I'm gonna bury the rest of it, along with all of you! Toodaloo! Hehehehe!!!

Ochako is about to chase after the villain, but the tremors become more violent as more explosions go off throughout the mines. 

Ochako: Dammit! *on coms* Deku! Deku, come in!

While this is going on, Ult. Big Chill and Bakugou still fighting each other off, each side not being able to completely stop the other. Big Chill keeps using his fire and ice to try and immobolize the amalgam, but Bakugou pushes through it all.

Ult. Big Chill: He can resist the extreme temperatures thanks to Big Chill's power. This wasn't the best choice to fight Kacchan with...

Ochako: *on coms* Deku! We've gotta get out of here now!

Ult. Big Chill: What's going on?

Ochako: *on coms* Valkanus is getting away, and he's gonna let the mine cave in! You need to get out of there!

Ult. Big Chill freezes, watching the mines tremble as he analyzes his options. He doesn't want to retreat, but knowing he can't stop Bakugou like this, he makes the hard decision. The ground continues to shake as the mine begins to crumble, but Bakugou remainz unfazed unphased, blasting Big Chill and catching him off guard as he gets shot into a wall.

Ult. Big Chill: URK!!!

The mutant Bakugou ignores the crumbling mineshaft, approaching his foe menacingly.

Bakugou: I know how that damn watch works, Deku! You might be powered up now, but every second you're transformed brings you closer to being you again! It's just a matter of time! THEN I can finish you off!

Ult. Big Chill: We've got bigger problems to worry about.

He points over his head, as the two of them see chunks of rubble and Taydenite beginning to collapse.

Bakugou: You think so falling rocks are gonna scare me?!

Ult. Big Chill: Fine. Be that way.

The Necrofriggian then phases through the ground, effectively fleeing from the fight. 

Bakugou: Hey! GET BACK HERE!!!

Meanwhile, Argit is still trying to free himself from the ice as the mine continues to cave in. He starts panicking before Ult. Big Chill flies in and grabs him, as they quickly rush out of the mine, before it collapses completely. The two of them go tumbling out of the entrance and land back in the empty aircraft hanger. 

Ultimate Big Chill finally times out, as the Ultimatrix beeps and flashes red before transforming back into Big Chill and then Izuku.

Izuku: Ngh... close one...

Ochako: You alright Deku?

Izuku: I'm fine, but Kacchan got away.

Ochako: ...We'll get him next time.

Izuku: Yeah. Next time... 

As the two of them are counting their losses, they see Valkanus still in his baby body playing in a huge pile of Taydenite. At the same time, Argit is making a poor attempt to slink away with a mine cart full of Valkanus' stash.

Ochako: What about those two?

Valkanus: Hey! This is my haul! I found it fair and square.

Ochako: While using it to build and sell illegal level five weapons on the side.

Valkanus: Oh yeah, what're you gonna do about it?

He blows a raspberry at her when several big lights shine down on them. A voice then calls out through a megaphone.

"Freeze! This is Magister Gilhil of the plumbers! We have you completely surrounded!"

Ochako: I think the plumbers can handle it.

Valkanus: Not again!

Valkanus is swiftly arrested, as his weapons and supply of Taydenite are taken into custody. While this is happening, Aizawa recapping the nights events with Deku and Ochako.

Aizawa: The plumbers will handle Valkanus, and track down all of the illegal weapons he's been selling around the area. You two did well, although...

Izuku: We're still not any closer to curing Kacchan.

Deku looks down with a defeated, the fight between them replaying in his mind. Aizawa can sense his disappointment and puts a hand on his shoulder. 

Aizawa: Don't be so hard on yourself, Midoriya. Today wasn't the day, but we will save him.

Izuku: Yeah...

Ochako: Today was just a battle Deku. But we're not gonna lose the war.

Izuku looks at her and nods with determination in his eyes.

"Yeah. I won't lose him again. I WILL save you Kacchan. Whether you want me to or not..." 

Chapter Text

The stars in the night sky shimmer over a medieval castle-like structure located somewhere in the mountains on the outskirts of the city. The castle is lined with rustic and medieval elements and tapestries as well as super advanced technology, with men in armored suits guarding the perimeter. Inside of the fortress, even more knights have been gathered together, awaiting their leader to speak to them. Finally, Lord Driscoll steps up to the podium to address his fellow knights.

Driscoll: Knights. As all of you are aware, our mission is a simple one; to protect this planet from the monsters who have invaded our world and called it their home. I've called you all here once again because in our quest to cleanse Earth of alien scum, it would appear we have a new enemy.

He clicks a remote that casts a holo-projection on the wall behind him. The projection displasys images and video footage of Bakugou going on a rampage all across Japan. 

Driscoll: For over a month, this amalgam of sorts has been tearing up the streets and causing widespread chaos and panic. No hero alive has been able to stop him yet, not even the transforming boy we clashed with. This mutant creature is not only extremely powerful... but also extremely aggressive and highly dangerous. Our mission now is to find this monster, then capture and detain it for further research. And if the beast cannot be contained... then we slay it.

All of the knights begin cheering with excitement as Driscoll turns, glaring at the footage once more. He can't help but be intrigued by this strange creature, unlike any alien they've encountered in the past. 

Music Insert: 

The camera cuts inside a crumbling warehouse bathed in shadows. Thunderous explosions shake the walls, and bursts of fire and crystal shards light up the darkness. Machinery groans under the strain as Deku, battered and panting, bolts between industrial equipment, dodging attacks that seem to come from every direction.

A blast of flame scorches the wall behind him—he rolls behind a large engine, his chest heaving, as he scolds the Omnitrix

Izuku: Now is not the time for a nap, Omnitrix! Come on, come on!

He slams the watch repeatedly. It's still glowing red—recharging. No good. Without warning, a crystal blade erupts through the metal just inches from his head, slicing clean through the machine like paper. Izuku yelps and dives, barely avoiding the deadly edge.

Izuku: Gah! For a watch, you’ve got a terrible sense of timing!

The machine is shredded apart as the towering form of the amalgam Bakugou—a warped, snarling hybrid of alien DNA—erupts from the wreckage, eyes glowing with unstable power.

Bakugou: Nowhere left to run, Deku! You shouldn'ta come looking for me. Now you're gonna pay the price!!!

Izuku backs up, hands raised, heart racing, but then...

BEEP. BEEP. BEEP. 

The Omnitrix flashes green once more. He quickly slams the core down. With a burst of green energy, his body morphs and elongates, with glowing blue tentacles wrapping around his limbs. Electrical energy courses through his body as he transforms into his Amperi form.  

Transformation Sequence:

"AMPFIBIAN!!!"

No sooner has he transformed than crystal projectiles fly at him—Ampfibian zips through the air, phasing between columns and hurling bolts of lightning back at Bakugou.

Ampfibian: Sorry, Kacchan—this is gonna sting!

He lashes out with his tentacles, gripping Bakugou and delivering a massive electrical surge. Bakugou screams, his body crackling—but snarls through the pain, grabbing Ampfibian and hurling him like a ragdoll into the wall. Ampfibian sticks for a moment, then peels off, flying in circles around the mutated boy, weaving between his wild attacks—lasers from his eyes, flames from his Pyronite arm, petrosapien crystals firing like shrapnel from his shoulder. 

Ampfibian keeps dodging as he begins channel energy, forming a glowing orb of lightning.

Ampfibian: Let’s see how you handle this!”

He hurls the orb of lightning and it explodes on impact, blasting Bakugou into a pile of crates. Bakugou snarls, then exhales a massive wave of frost, coating the area in ice and mist. He vanishes into the haze.

Ampfibian: Kacchan using stealth? That’s not like him… those alien instincts must be taking over.

Ampfibian hovers silently—scanning the area. He feels a slight vibration, but it's too late. Bakugou erupts from the floor like a ghost, phasing up through the concrete and smashing Ampfibian with a Vulpimancer arm, sending him hurtling into the ceiling. He crashes down, groaning in a crater.

Bakugou descends, arm morphing into a Petrosapien blade once more, snarling like a predator closing in. Ampfibian glances behind, spotting a generator. In a desperate move, he grabs the it with two tentacles, and the blade with his other two. He then channels a massive electrical surge back through the weapon into Bakugou.

Bakugou: AAAAAAAAAARGH!!!

The surge is blinding—electric arcs dance across the warehouse, illuminating every corner. The shockwave rattles windows, when Aizawa and Ochako arrive outside the warehouse.

Aizawa: Looks like he's already engaged Bakugou.

Ochako: Then let's help him out!

With swift precision, Ochako manifests several floating platforms, creating a staircase. She and Aizawa leap rooftop to rooftop until they crash through the skylight, landing amidst chaos. Below, Ampfibian and Bakugou clash in a whirlwind of power.

Ochako throws up a protective barrier over Izuku and fires off a barrage of mana blasts at Bakugou.

Bakugou: Rrgh! Outta my way, Cheeks!

The amalgam snarls as he starts hammering away at the barrier. 

Ampfibian: We can’t keep this up for long!

Ochako: Don’t worry, Deku! Reinforcements are on their way!

Suddenly, several figures in medieval samurai armor swing in through the windows with a CRASH! The knights smash through the glass as they land with clanking boots and brandished weapons, immediately charging toward Bakugou. 

Ampfibian: The Forever Knights?!

Knight Leader: Bring down the beast!

The Knight Leader raises his laser lance toward Bakugou as the knights all converge on him. 

Ampfibian: Wait, they’re attacking Kacchan?

Ochako: So… they’re on our side?

Just then, the Knight leader spots Ampfibian, recognizing the Omnitrix on his chest.

Knight Leader: Capture the Amperi, as well!

At his command, several Knights break formation, rushing the trio with electro-nets and stun blasters.

Ampfibian: Yeah. Definitely not on our side.

Before he can react, a Knight fires a high-tech net that engulfs Ampfibian. He convulses as the net absorbs his lightning, its tight weave too small for him to slip through.

Ampfibian: Ack!

Ochako: Deku! Hang on!

As she blasts back a charging Knight, Aizawa’s scarf lashes out and yanks two more off their feet. Bakugou, meanwhile, fends off wave after wave of the knights—his crystal arm deflecting the lances beams, his XLR8 tail slashing through attackers, and his Goop arm launching them across the warehouse.

Bakugou: You think you tin cans can take me?! *fires a neuroshock* I CAN DO THIS ALL NIGHT!

With a roar, he stomps the ground—Vaxasaurian strength triggering a shockwave that hurls several Knights back. But they keep coming. For every one he drops, two more charge in. He lashes out with fire, lightning, claws, and unrelenting brute force.

Bakugou: ROOOOOOAAAAR!!!

High above a higher-ranking knight watches from the broken skylight. Calmly, he levels a specialized launcher, takes aim at the monster and fires.  A collar-shaped projectile clamps around Bakugou’s neck mid-roar.

Bakugou: GRAAAAAAAAAAAAGHH!!!

The amalgam growls and convulses, red electricity crackling through his body. He stumbles, eyes blazing with fury as he glares up at the Knight that attacked him. Bakugou raises his hand to attack but nothing happens. No flames. No lightning. He tries again, but still nothing. He attempts to phase or take flight, but none of his powers are responding. 

Bakugou: What… the hell?!

Bakugou grips at the collar on his neck, trying to take it off, which just shocks him again, making him howl in agony. The Knights seize their opening, launching electro-nets and chains that shock him on contact. Even still, Bakugou thrashes wildly and knocks a few back—but he’s slowing down. The collar on his neck isn't just restraining his powers, it's acting as a sedative. 

Bakugou: *gritting his teeth* Bas…tards…

He collapses to one knee as the nets stack and the sedatives kick in. More chains wrap around his limbs as Bakugou is now slogging while attempting to fight back. He growls weakly, then blacks out.

Ampfibian *straining in his net*: K-Kacchan!

Cramped and bound, the Amperi fights to reach the Omnitrix. His appendages just barely brush the dial, as a blinding green flash of light floods the warehouse. The net shreds apart as the towering Vaxasaurian emerges, roaring. 

"HUMUNGOUSAUR!!!"

The Knights freeze, some stumbling back in panic.

Knight Soldier: Fall back! FALL BACK!!

Humungousaur slams a fist down, sending debris and bodies flying. One van's engine dies as he flips it over like a toy. Others scramble to drag the restrained Bakugou into a waiting vehicle.

Knight Soldier: C'mon men! Hurry!

Humungousaur: RAAAAAAGH!!!

The Vaxisaurian attempts to chase after them, but it’s too late—the van peels away, tires screeching as the remaining Knights retreat in a chaotic convoy. Humungousaur crashes through the wall in pursuit, but the Knights are already out of sight. The Vaxisaurian grumbles as he hits the Omnitrix, transforming back to human. Izuku hits the ground, panting, exhausted and human again.

Izuku: *clenching his fists* Damn it… we lost him. Ngh—!

Izuku drops to a knee. He looks to the retreating lights of the van, eyes filled with worry. Ochako rushes to him, throwing his arm over her shoulder.

Ochako: Hey—easy! We’ll get him back. I promise.

Izuku: Why would the Forever Knights want Bakugou?

Ochako kneels beside him, then looks around—spotting a dropped laser lance. She picks it up, eyes narrowing.

Ochako: Let's find out.

Back at the Plumber Base, beneath UA, Thirteen examines the weapon at a lab station while Izuku and Ochako stand nearby. She carefully rotates the shaft of the lance, exposing its inner components.

Thirteen: Ether point energy module. Antenna focus emitter. Good for about 35 minutes of continuous fire at point 6 terawatts.

She twists off the base, revealing a pulsing energy cell.

Thirteen: These things are level 5 technology.

Ochako: Is that... bad?

Thirteen: Planet Earth's only at level 2. These things aren't even legal here. The Knights weren't messing around.

Izuku: They had a whole stash of these when they ambushed us... before they got away with Kacchan.

Aizawa joins them, arms crossed.

Aizawa: We've had trouble with the Forever Knights before. Their entire organization is an anti-alien supremacist group.

Thirteen: They usually raid alien crash sites or black markets. Study whatever they get their hands on and reverse engineer it to improve their arsenal. 

Aizawa: Meaning they either captured Bakugou for research-

Ochako: -or they're gonna put him down...

Izuku: We have to get to him before that happens... but how would we even know where they're holding him?

Ochako points at the laser lance

Ochako: We'll use that.

The scene shifts to the group outside of the base. Ochako floats in front of the Rust Bucket, the Lance in her hand, glowing faintly. Inside the vehicle: All Might drives, with Izuku and Aizawa watching her through the windshield.

Izuku: Are you sure this is gonna work?

Ochako: Not entirely. Last time I tried this, I was tracking you down when the villains raided the summer camp. If I could do it back then, my quirk should let trace this back to the people who used to own it.

She concentrates. Her eyes flicker with light as she syncs with the weapon. A pulse runs through it. Suddenly, the Lance glows brighter and points north like a compass needle.

Ochako: Got something! Follow me!

Ochako hovers forward as the Rust Bucket speeds through the trees behind Ochako as she leads them down a forest road to a looming stone castle built into a cliffside. Watchtowers and guards patrol the perimeter.

Izuku: Huh, subtle. Nobody would think to look for knights in there.

Ochako: The place is crawling with knights. How do we get in?

Izuku: We can cover more ground if we split up. All Might, Eraserhead, and Thirteen can keep the guards busy. Ochako and I can sneak into the fortress and look for Kacchan. We'll meet up here once we have him and get the heck outta here.

All Might: Alright, be careful, you two.

Izuku and Ochako nod, hop out, and vanish into the woods toward the fortress. All Might watches them go, troubled.

Aizawa: You alright?

All Might: Yeah, yeah, just... worried about Young Midoriya is all...

Aizawa: Yeah, I feel ya. Kid's been through a lot. Uraraka too. But they'll only get stronger from all of this.

All Might: I guess you're right. They've both come so far since that first battle with Young Bakugou and Iida. I'm proud of them, but I can't help also being worried.

Aizawa: Have a little faith. He is the wielder of the Omnitrix after all. It's good to have an Anodite on our side as well...

All Might:...

Aizawa look at him with a bit of confusion.

Aizawa: You didn't know?

All Might: I... I figured it out. I don't think she knows.

Aizawa: Should we tell her?

All Might: Now's not the best time. Let's deal with Young Bakugou first. One problem at a time...

They exchange a nod and head back toward the Rust Bucket, ready for battle. Meanwhile, within the castle walls, Driscoll walks into the main lab. There are some knights acting as guards, while their scientists are at the computer terminals running tests and analyses on their captive. All of their computers are connected to a massive energy cage in the center of the room, containing the mutated Bakugou who is still grumbling and growling as he tries to slash through the plasm acage. 

Bakugou: Nnh! RAH!!! HA!!!

Bakugou keeps trying to break out using every power in his arsenal. He shoots flames and laser beams and fires crystal projectiles, but they all just dissipate upon making contact. He then tries to muscle his way through, using Tetramand, Vaxisaurian, and Appoplexian strength to break through the field, but those abilities are negated as well. He then tries to then phase his way out with Big Chill's powers, but he just receives another electrical shock and falls to the bottom of the cage. Driscoll smirks as he approaches the amalgam.

Driscoll: You are truly an astonishing creature.

Bakugou: Bastard! Lemme out before I bust this thing open myself and tear you limb from limb!!!

Driscoll: Oh by all means, keep struggling. The more you do, the more of you we get to analyze. That's not just any cage, every time you use one of your alien powers the energy field not only negates it, but also scans the DNA and technique.

Bakugou: I don't give a fuck what it does!

Bakugou continues thrashing around, not listening to anything Driscoll has to say.

Driscoll: Tell me, what do you know about one Izuku Midoriya?

Bakugou: Deku? He's a lying little bastard that's always standing in my way! What's it to ya?!

Driscoll: We've had trouble with your "friend" before and after a careful analysis of the boy's own power, it would seem your current amalgamation stems from every one of his transformations. It's truly amazing. You've somehow absorbed a multitude of interstellar beings into one body, all armed with their powers.

Bakugou: Rgh! If you're gonna keep yappin' in my ear, then tell me what's the deal with that damn watch!!!

Driscoll: That, my boy, is the part we're so desperate to find out ourselves. At first we believed it to be some kind of quirk, but would appear the device is what allows the boy to gain control over these alien forms.

Bakugou: I knew he fucking cheated!!!

Driscoll: Just imagine, an entire one-man-alien army at the simple push of a button. Imagine what kind of threat that would pose to our world?

Bakugou: The hell are you goin' on about aliens for? You think I'm some kinda moron?!

Driscoll: Oh my dear boy. You don't even know what's become of you.

The knight leader clicks a remote, casting a projection showing footage of several alien encounters the Knights have had in the past, as well as footage of Deku fighting villains in alien form.

Driscoll: The world may not realize it, but this planet is already infested with alien scum. Intruders from the stars who seek to invade and colonize our world. Beings with strange powers, stranger than the quirks we see on a regular basis. And with the knowledge we'll gain from studying you... we'll find a way to destroy every single one of them.

Driscoll smirks and walks away as Bakugou is left wondering. He looks down at himself, a small hint of sanity and recognition returning. He thinks back to all of the times before when he'd touched the Omnitrix and mutated into a hybrid of one of Deku's transformations. He'd never truly questioned the power before, but now...

"Alien... is Deku an alien... what does that make me? Am... I an alien?!"

He keeps thinking but the insanity of his transformation takes over again.

"Lied to me... laughed behind my back... turned me into some alien freak... Deku... "

Music Insert:

On the outskirts of the Forever Knights' fortress,  Izuku and Ochako crouch behind a ruined stone wall, scanning the heavily-guarded perimeter of the fortress. Knights in gleaming armor, enhanced with stolen alien tech, patrol with energy rifles and security drones hovering above.

Ochako: *whispering* How are we supposed to get in? It’s crawling with those tin cans.

Izuku: *whispering* Their security is all stolen alien tech they repurposed for their defense measures. So I say we go ahead and hack the system. 

Izuku slaps down the Omnitrix. A flash of green light transforms him into Upgrade, a sleek, black-liquid metal alien lined with pulsing neon-green circuitry. He melts into the ground like a puddle and slithers forward.  Upgrade slips past guards, slides into a nearby security terminal, and fuses with it. His circuitry spreads like roots through the panel as beeping sounds echo. The door clicks open silently.

The nearest guards turn, confused. Before they can investigate further, Upgrade shoots from the shadows and shocks them with a stun blast.

Upgrade: Clear! Let’s move!

Ochako sprints from cover, dashing into the now-unlocked doorway. Inside, the halls are dim and lined with surveillance cameras. She's enjoying sneaking around and starts humming a spy movie theme as they move.

Upgrade: *whispering* Keep it down!

Ochako: *whispering* Sorry!

They reach a long corridor lined with more knights. Upgrade targets the cameras first—each one short-circuits with a sharp zap as he fires controlled blasts.

Upgrade: Cameras down. Go loud.

Ochako: Hehehe!!

The duo charges in—Ochako uses her Gunhead Martial Arts, drop kicking two knights with a flurry of precise strikes while Upgrade disables another with a tech-surge through his armor. Once the coast is clear, they duck behind a support beam, overhearing a trio of knights conversing up ahead.

Upgrade: Shh! Listen.

Knight 1: Oh boy, I'm beat. What a haul that was.

Knight 2: You said it. What the hell is it anyway?

Knight 1: Some kinda freak amalgam of extraterrestrial creatures. Lord Driscoll said they're taking it to the lab for further study.

Knight 3: I heard the monster's actually some kid that got mutated in some freak accident. Wrong place, wrong time, I guess.

Upgrade: They're talking about Kacchan.

Ochako: We need to find that lab—now—before they do something irreversible.

Suddenly, a sharp beep cuts through the silence as the Omnitrix on Upgrade's chest glows yellow.

Omnitrix: Uncataloged alien DNA detected. Please stand by...

Upgrade: No, no, no—shut up!

Omnitrix: Uncataloged alien DNA detected. Please stand by...

Ochako: Turn it off!

Upgrade: I'm trying!

Music Insert:

Upgrade tries hitting the Omnitrix to shut it off but the beeping persists. The sound echoes down the hall as a knight turns toward their hiding spot.

Knight 4: Hey! Who’s there?! Intruders!

Ochako: Shoot! We gotta move!

They sprint down the corridor as sirens blare and red lights flash. However, they don't get far as more guards surround them. 

Knight 2: Hands above your heads!

Upgrade: So much for stealth.

The Knights open fire as Upgrade slides between blasts, merging with and disabling their weapons, while tripping others with tendrils of upgraded alien tech. Ochako flips over a guard and blasts him with a energy shockwave, knocking him into his comrades.  Suddenly, a  bolt of electricity slams into Upgrade, locking up his body.

Upgrade: Agh! C-C-Can’t move!

A high-voltage net is launched, wrapping around him and surging with energy. Upgrade twitches and jerks, his liquid form distorting.

Ochako: Hang on! I’ll get you—AAAH!

A sudden stun blast nails her in the side as she collapses, unconcious.

Upgrade: Ochako!

With a growl, Upgrade claws at the Omnitrix and slams it. A burst of green light engulfs him as he transforms into his towering tiger-like Appoplexian form. 

Rath: RAAAAAAAAAATH!!!  LEMME TELL YOU SOMETHING, FOREVER KNIGHTS! YOU DON’T TOUCH MY FRIEND! YOU DON’T EVEN LOOK AT HER SIDEWAYS!

With a roar, Rath lunges forward, claws flashing. He shreds through armor, tosses knights like ragdolls, and smashes weapons to pieces. One knight charges, but Rath shoulder-checks him into a wall. Rath extends his claws and begins brutally attacking the knights, slicing their swords in half and throwing them around the room. More knights begin surrounding him, but Rath leaps up in the air, does a flip, and strikes the ground with his claw, causing a shockwave that knocks them all back.

Rath: RAAAAAAAH! WHO'S NEXT? WHO WANTS A PIECE?!

More knights arrive. Rath leaps high and SLAMS the ground with a clawed fist—BOOM! A shockwave knocks them flying.  But then, several. darts hit Rath’s back.

Rath: Grrr... What the—?!

He pulls them out, but the tranquilizer kicks in immediately . His knees buckle. Vision blurs. He falls hard, skidding to a stop.  From the shadows, Driscoll steps out, holding a strange alien blaster.

Driscoll:  So these are the intruders. The changeling... and some kind of energy-based hybrid. Interesting.

The Omnitrix times out with a hiss—Rath vanishes, and Izuku lies unconscious, panting on the floor.

Driscoll: Lock them both in the dungeon. We’ll begin the tests at first light.

Knight 5: As you command, my lord.

The unconscious heroes are dragged away as the scene shifts to a dimly lit, metallic cell deep underground. A flickering light hums overhead. Izuku groans, blinking his eyes open. Beside him, Ochako stirs.

Izuku: Ugh, my head. Where the heck are we now?

Ochako: Not sure. I was blacked out when they brought us here.

A low, distorted voice echoes from the shadows.

"This is the Forever Knight's alien prison."

Both teens jolt, scrambling to their feet as they whip around.

Ochako: Who said that?!

From the darkness, a figure steps forward — a tall, black-and-white, salamander-like alien with a long fin running down his head and three glowing, multicolored eyes.

Prisoner 775: Apologies. I did not mean to frighten you.

Izuku: Who are you?

Prisoner 775: I could be asking you that question. Human, no doubt, but not a knight if you got thrown in here.

Izuku: You can call me Deku. And this is partner, Lucky Girl. We're Plumbers in training.

Ochako: We came here to break out, our friend. He was taken here by the Knights.

The alien looks down solemnly.

Prisoner 775: If the Knights already have him and he’s not in this pit... he’s probably gone.

Izuku: What is "here" anyway? You said something about an alien prison.

Zsef: The Knight's dungeon. This is where they lock up all of the aliens they find here on Earth, like me. My name is Zsef.

Izuku: Well, I guess that explains the Omnitrix being on the fritz.

Ochako: Don't worry. We'll get you outta here, it's gonna be okay.

Zsef: Nothing will EVER BE OKAY AGAIN!

Ochako flinches, stepping back. Zsef’s face twists with anguish, then softens as he lowers his gaze, guilt-ridden.

Zsef: I... I’m sorry. That wasn’t directed at you.

Ochako: How long have you been here?

Zsef: Years... maybe decades. Time’s hard to measure in a tomb like this. Back on my homeworld, I fought against an oppressive dictator. It was his forces who exiled me to this backwater world. I explained this to those knights hundreds of times! They did not believe me.

Izuku: The Plumbers will listen. We’ll make sure of it. You deserve to go home.

Zsef: I NO LONGER HAVE A HOME!! While I rotted in their prison, the revolution was lost! My mate, my children gone... all gone...

Zsef drops to his knees, the weight of his grief finally breaking through. His voice cracks, barely a whisper now.  Izuku and Ochako exchange heartbroken glances, their resolve hardening.

Zsef: There is nothing left to live for.

Ochako: No way! There's always something to live for! You could even the score!

Izuku: Absolutely! You could seek justice!

Zsef looks up, eyes glimmering with a renewed spark.

Zsef: Justice?... Yes...

Izuku: First, we've gotta get outta this cell. Can we contact All Might and Eraserhead?

Suddenly, the Omnitrix beeps yellow again.

Omnitrix: Uncataloged alien DNA detected.

Izuku: Oh, sorry, Zsef. Just hold still for a sec.

Izuku raises the Omnitrix. It emits a scanning beam that passes over Zsef.

Omnitrix: Alien DNA scanned and recognized. Merlinisapien. Scan complete.

Izuku: Thanks.

Ochako: Looks like my coms are down.

Zsef: All communication is jammed inside these cells. Only the Knights’ keys open the doors... and they guard them well.

The trio eyes the high-tech alien barrier sealing them in.

Ochako: How do we break out?

Izuku: No problem. I've just gotta put on my thinking cap!

Izuku activates the Omnitrix, transforming into his Galvan form.

Grey Matter: Hey, gimme a lift up.

Ochako nods and hoists him toward the gate. Grey Matter immediately starts analyzing the lock system.

Grey Matter: Hmm... Modified Amperi security vault. Level 4 at best. Plasma-reinforced, containment-grade. Six potential weak points — let’s see...

He scurries between circuit nodes, scanning, tapping, rerouting. Finally, his tiny fingers twist a wire into place.

Grey Matter: Eureka. Reconfiguring energy matrix... now!

The energy barrier sparks, then flickers out entirely. Grey Matter hops down and taps the Omnitrix, reverting to human. Zsef steps beyond the threshold, the shock of freedom hitting him like a tidal wave.

Zsef: I'm... free.

He trembles, eyes wide, slowly placing a hand against the cold outer wall — the first time in years he’s touched anything beyond his cell.

Ochako: Not time to celebrate yet. We still need to find our friend—and free everyone else while we’re at it.

Izuku: Right. I have to ask Zsef, but will you help us? We could use someone who knows this place.

Zsef: You freed me from a lifetime of torment. I owe you everything. And I swear—I won’t let anyone else endure what I have. Let’s burn this prison to the ground.

Izuku smiles at him, then refocuses his attention to the task at hand.

Izuku: Right. I'll contact the pros and tell them to meet up with Zsef. We'll go after Kacchan. Hopefully, the jailbreak will be enough of a distraction for them.

Zsef: If you're going to find your friend, their main lab is just down this hallway.

Ochako: Gotcha. Be careful, Zsef. We'll meet up with you once we've found our friend.

Zsef: I will, and thank you again. You have no idea what this means to me.

The teens smile, then sprint into the halls, disabling cell locks as they go. Behind them, Zsef watches the doors open one by one, the tide of freedom rising.

Ochako: There's so many of them, and they're all crammed up in those cells. This is just... awful.

Izuku: Don't worry. We'll break them out and make sure those knights get put away for good!

They keep running until they reach the entrance to the lab.

Ochako: This is it. Wanna do the honors?

Izuku: Let's bust 'em up!

Izuku activates the Omnitrix and slams down on the core, as his body is coated in yellow armor, with steel claws and two pistons forming out of his arms. In a flash of light, Deku transforms into his Talpaedan form.

Transformation Sequence:

"ARMODRILLO!!!"

The scene then shifts to the inside of the lab, where Bakugou is still desperately trying to break free.

Bakugou: Rgh! Just you wait, assholes! When I bust outta here, I'm weld that armor to your skin! Right after I bury you fuckers under your own castle!!!

Driscoll: Try all you'd like. This technology has the full capability of restraining a fully grown Vaxisaurian. A being with only a fraction of that strength has no chance of escape.

Just as he says this, however, the whole room begins to rumble. The knights and Bakugou scan their surroundings as the lab doors go flying off the hinges as Armodrillo and Ochako break into the lab, with multiple alarms blaring.

Alarm: Warning. Security breach. Code Red. Entire prison sector compromised.

Bakugou: Deku?!

Driscoll: What?! Impossible!

Ochako: Look, there's Bakugou!

Music Insert:

Driscoll: Knights! Retrieve the prisoners and capture those intruders! Not one alien escapes this castle alive!

Armodrillo: I don't think so, your highness.

Armodrillo then slams his hand on the ground and begins vibrating the lab once more, causing rubble and debris to block their exit.

Armodrillo: Nobody's goin' anywhere until we get our friend!

Driscoll: You'll die along with him. *draws sword* ATTACK!

The knights begin charging at the two heroes, drawing their weapons. Armodrillo rushes at them, knocking them left and right with his massive drill arms. They try blasting and slashing at him, but his armored hide is too thick for them to blast through.

Armodrillo: I'll hold them off! Head to the computer terminal and find a way for us to get Kacchan outta here!

Ochako: Gotcha!

She runs toward the computer as Armodrillo continues duking it out with the knights until Driscoll is the only one left standing. He draws his sword and charges toward Armodrillo, his sword colliding with his armor.

Driscoll: You are truly astonishing! A human with the ability to transform into a plethora of creatures at will!

Armodrillo: Yeah, I get that a lot.

Driscoll: Once your powers are ours, there will be no telling how strong our forces will become. Earth shall be free of alien scum as it was in days of old!

Armodrillo: Not if I have anything to say about it!

The two continue dueling with each other, exchanging slashes and arm attacks until Armodrillo knocks him back and uses his powers to cause the ground to shake, throwing him off balance. Driscoll looks up as Armodrillo leaps toward him, about to finish the fight, when he puts up his hand and blasts the alien back with an EMP. Armodrillo goes sliding across the floor, holding his head and looking toward his foe.

Armodrillo: Ugh, what was that?

Driscoll: You didn't think I was some powerless old fool, did you? My quirk allows me to manipulate electromagnetic fields.

Driscoll holds up his hand and fires another EMP at Armodrillo, pushing the alien back. He keeps using this technique, not allowing Armodrillo any room to get close.

Armodrillo: Ugh! He's messing with the metal in my armor! I've just gotta stall him long enough!

While this is happening, Ochako rushing toward the computer terminal, fighting off any remaining knights in her way. She fights back, using both her energy blasts and Gunhead Martial Arts to take them down until she finally reaches the terminal and begins messing with the controls.

Ochako: C'mon, one of these has to be some kinda system shut down or something!

As she's looking for a way to release the prisoners and safely release Bakugou, Armodrillo is still getting slammed around by Driscoll.

Armodrillo: *panting* Ngh... that all you've got? I can *panting* do this all day.

Driscoll smirks as he puts his hands up, letting out another EMP wave. This time, however, instead of affecting Armodrillo, he pulls together the metal within the lab as it begins to coat around him, creating an armored suit paired with a larger sword.

Armodrillo: I had to ask.

Driscoll: BEHOLD! THE FOREVER KING!!

The two go at it again, exchanging slashes and fisticuffs, but the suit still allows Driscoll's quirk to be utilized, making it hard for Armodrillo to fight back. He's getting with slashes and wave after wave of EMP blasts.

"I can't fight him this way, time to switch out!"

As Driscoll is about to slash at Armodrillo again, he hits the Omnitrix and disappears from Driscoll's sight, making him belief for a second that he vanquished Izuku. However, green roots then grow up from the ground and merge into his Methanosian form.

"SWAMPFIRE!!!"

The Methanosian then ignites his hands and shoots several fireballs at Driscoll, knocking him back. Swampfire doesn't let up, shooting flame geysers at the armor in an attempt to superheat and melt it, while Driscoll does what he can do to defend himself. While they're still fighting, Ochako is still working at the computer when Aizawa contacts her on their coms.

Aizawa: *on coms* Uraraka, we made our way in, and we're evacuating as many prisoners as we can, but most of the gates are still locked, and this place is crawling with knights. Think you can find a way to unlock the cells and disable the defenses?

Ochako: Working on it! I can't find a way to unlock the gates from here.

Aizawa: *on coms* Try looking for a way to shut down the entire facility.

Ochako: I'm trying!

She keeps typing when she looks over and sees an emergency shutdown switch pop up on the console.

Ochako: Wait, I think I got it!

As she goes to hit the button, Driscoll looks over and sees this, with horror in his eyes!

Driscoll: STOP YOU, FOOL!!!

His warning goes unheard as Uraraka presses the button, causing the lab as well as the entire castle to shut down and go dark, now only being lit up by alarms and red flashing lights. In the dungeon, all of the cells open, freeing the prisoners inside.

Computer: Warning. Complete system shutdown in progress. All systems offline.

Ochako: YES!!

DRISCOLL: NO! WHAT HAVE YOU DONE?!

Swampfire and Ochako look at him confused until they hear some static crackling as they look toward the center of the room, seeing Bakugou's prison flicker before dissipating. Bakugou has been freed and with the collar deactivated, his powers have return. Bakugou rips off the collar and ignites his Heatblast arm, letting out a roar.

Bakugou: DEKUUUUUUUUUUU!!!

Swampfire: Oh man! Just can't catch a break tonight!

Before either of them can go on the offensive, Driscoll charges into battle, swinging his sword at the boy as it snaps upon impact, leaving Driscoll terrified. Bakugou smirks as he grabs the Forever King Armor and effortlessly tears it in half. Driscoll drops to the floor and tries to run as Bakugou grabs him with his Diamondhead arm and charges up his Neuroblasts.

Bakugou: Hehehe! Knighty knight!

As he's about to fire his beams, he's hit with a fireball to the head, causing him to release his grip.

Bakugou: RGH!!!

Swampfire: This is between you and me, Kacchan!

Bakugou: I didn't ask for your stinkin' help Deku! So don't blame me for what happens next!

Bakugou rushes at the Methanosian with XLR8 speed, smashing his body to pieces. He turns around to see Swampfire regenerating and throwing several seeds in his direction. The seeds bury themselves into the ground before growing out into several large vines that constrict Bakugou, holding him in place. 

Swampfire then comes running at the boy, igniting his hands and landing several punches before being blasted away by Katsuki's Chromastone blasts. Swampfire is sent flying backward as Katsuki breaks out of the vines and approaches the Methanosian.

Bakugou: Nice try, Deku, but that trick won't work on me! Just face it! There's no trick you can pull that can top me now! So you just lay down and DIE!!!

Swampfire: *panting* Sorry, Kacchan. I didn't want it to come to this, but I don't have any other choice!

Music Insert:

Swampfire begins crackling with green lightning as he slams the Omnitrix on his chest as a green light wraps around him. His body transforms from a muck-grass-like material to a more sturdy wood-like substance. He grows several blue flame pods on his arms and one massive pod on his back and face.

"ULTIMATE SWAMPFIRE!!!"

Bakugou is caught off guard by the ultimate transformation but steels himself and rushes toward his rival anyway. Ult. Swampfire just puts up his arms and fires a massive blast of blue fire at the mutant boy, sending him crashing into a wall. He walks up to Bakugou, cracking his knuckles.

Ult. Swampfire: Whaddya say, Kacchan? Round two?

Bakugou gets even more enraged by this and fires several Diamondhead crystals that all shatter against Ult. Swampfire's thicker and more durable hide. The Methanosian takes a running start and leaps up high into the air, firing a blue flame orb from his hand that explodes into several smaller fireballs that scatter and attack Bakugou. He tries to retaliate and fight back, but the attack blinds him and leaves him open. 

Ult. Swampfire uses this to his advantage, running toward him and landing a solid uppercut on Bakugou. He goes flying but lands on his feet, sliding back on the floor, still furious at his rival. With his Upchuck tongues, he grabs a chunk of the ground and eats it before firing the projectile at Ult. Swampfire. He charges up a blue fireball in his hand and fires it at the vomit projectile, creating a massive green and blue explosion as smoke fills the lab.

Ochako: Deku! Ack!

She starts coughing as Ult. Swampfire looks around the area for his rival, remembering a similar tactic he pulled earlier. He then feels a chill as Bakugou begins using Big Chill's powers to phase through the floor and ceiling. Every time he passes by Ult. Swampfire, part of him begins to freeze up, slowing the Methanosian down. He keeps doing this as Ult. Swampfire closes his eyes and begins to generate a blue heat around his body.

Ult. Swampfire: CUT IT OUT!!!

As the ice begins to melt and drip off him, he unleashes an explosive flame body attack that knocks him back and sets the entire room on fire. Bakugou is burned and sent flying one more, crashing into the lab's computer. He looks up and see's Ult. Swampfire still approaches him before outstretching his Heatblast Arm and letting out a full-power flame geyser in an attempt to incinerate him. 

However, Ult. Swampfire is able to withstand the heat output. In his Ultimate form, he's to generate and absorb more heat than a Pyronite in its base form. The evolved Methanosian then grows several wooden spikes on his arms and slams them into Bakugou, knocking him back further.

Ult. Swampfire: METHANOS SMASH!!!

The amalgam is sent reeling back as Ult. Swampfire continues his thorny onslaught, slamming his spiked arms into him repeatedly before getting around him and holding him back.

Ult. Swampfire: Just give up Kacchan! You have to stop!

Bakugou: Not a chance! Ngh! Not until I get some answers!

Bakugou then uses Goop's power to make his limbs acidic to the touch, burning away at Ult. Swampfire's tree-like skin, before knocking him away.

Ult. Swampfire: ARGH!!!

He glares at his foe, trying to regenerate but notices nothing happening.

Ult. Swampfire: Nnh... can't regenerate in this form.

Bakugou glares at him and takes off, flying toward him with XLR8 speed, but Ult. Swampfire's manages to catch the amalgam and slam him into the central computer in the lab. Bakugou is about to get back up when he realizes where he's landed and smirks as he begins using feedback's power to siphon all of the electricity from within the lab.

Ult. Swampfire and Ochako both see him charging up and go on the defensive.

Ult. Swampfire: SHIELD UP!!!

Ochako quickly puts up her energy shield as Bakugou fires a huge beam of lightning from his tail. Ult. Swampfire puts up his hands, pushing back against the beam with his own blue flames. Bakugou smirks as he adds on his Neuroshocks and Chromastone Lasers to the beam making it more powerful. Ult. Swampfire keeps pushing, but the combined attacks begin to overwhelm him.

Ult. Swampfire: C'mon... c'mon!

He keeps pushing as green lightning crackles around his body.

Ult. Swampfire: One For All... One Hundred Percent...

The evolved methanosian then roots himself into the ground and reinforces his armored skin as he prepares to make one final blast.

Ult. Swampfire: COBALT INFERNO!!!

Ult. Swampfire releases every ounce of fire and heat within his body, releasing it into one final attack, pushing back against Bakugou's combined beam. The attacks continue to collide and merge as the struggle grows more and more unstable. Ochako sees this.

Ochako: That doesn't look right!

Ult. Swampfire: RGH!!! KACCHAN! YOU HAVE TO STOP!!!

Bakugou: I'LL STOP WHEN I'M GOOD AND DEAD!!!

The two of them continue the beam struggle as the energy grows more and more unstable before merging into one and letting out a massive explosion that knocks the both of them back. Ochako manages to shield herself from the blast and when the smoke and dust clear she sees the entire lab and castle is in ruins. Ultimate Swampfire is lying motionless on the ground.

Ochako: Oh no... Deku!!!

She runs over to the evolved Methanosian as he's still crackling with a bit of static as the Ultimatrix begins to beep and flash red before he's transformed into base Swampfire and then back to human. As Ochako is checking up on him, Bakugou gets up, clearing the rubble off him. He looks over at his rival now weakened. Part of him wants to rush over and end it but something inside him is causing him to hesitate.

"He's down... I could end him... right now... once and for all..."

Bakugou himself is weakened and drained from the fight. He attempts to limp over to the two of them, but still he hesitates.

" Are you okay?"

Suddenly, he sees a younger Deku standing before him. He remembers this moment clearly in his mind. After he'd fallen, Deku raced down to help him. This wasn't the all powerful deceiving rival he'd be chasing after all this time, it was someone innocent offering out a helping hand.

Deku: Ka...chan...

The mutant Bakugou looks at him for a moment before huffing and shaking it off.

Bakugou: Next time we're finishing things...

With that, Bakugou spreads his Necrofriggian wings and takes off into the night. Amid the chaos, Driscoll crawls from beneath the wreckage, battered and bloodied. His armor is cracked, one arm clearly broken, and he limps toward the exit. The walls crackle with sparks. Fires flicker in the distance.

Driscoll: *gritting his teeth* Just need to make it to the comms... get out... regroup...

Suddenly, a blow comes out of nowhere, sending him sprawling into the debris. Zsef materializes from the shadows, shimmering into view with a deep, echoing growl. His eyes glow—three burning coals of fury.

Zsef: Driscoll!

Driscoll scrambles, sheer panic in his eyes.

Driscoll: No—n-no, stay back!

He grabs a laser lance and fires wildly, but Zsef is already gone—vanished again into the dark. The lab flickers with sparks as shadows shift. WHAM! Another strike. Then another. Driscoll is hit from all sides, each blow more savage than the last. He's knocked to the ground, gasping for breath. Zsef reappears, standing over him—towering, monstrous.

Zsef: Years I spent in there! YEARS! I DID NOTHING!!!

Driscoll stumbles backward, grabbing a laser lance and trying to fire at Zsef, but he dodges and disappears once more before pouncing onto the knight and hissing.

Driscoll: L-Let me go! P-Please!

Zsef: Let you go?! To do what? Imprison more aliens? Experiment on us? Take us away from our homes?!

Driscoll tries to crawl away again, but Zsef grabs him and slashes his face. The knight screams, clutching his eye, blood trailing from a fresh, deep scar.

Driscoll: AAAAAAAAAHHH!!!

In his defenseless state, he begins panicking on the ground as Zsef latches onto the knight, restraining him.

Zsef: I lost EVERYTHING because of you! And now you—

He pins Driscoll down, his tail poised with the stinger unsheathed and quivering above Driscoll’s chest. 

Zsef: —you will pay for your crimes.

As Driscoll is panicking, completely helpless, Izuku’s voice cuts through the moment.

Izuku: HEY!

Zsef quickly turns his head to see his former cellmate.

Izuku: That's far enough, Zsef!

Zsef whirls toward him, eyes still burning.

Zsef: Don’t try and stop me! This monster deserves to suffer—like I did! My family is gone because of him!

Izuku: I know he hurt you. I can't imagine what kind of torture you have been through. That guy deserves what's coming to him... but if you go through with this... there's no coming back from crossing that line. Don't become the monster they made you out to be...

Zsef trembles, the stinger still raised, every muscle in his body tight with rage and grief. Zsef’s breath trembles. He looks down at Driscoll—sniveling, bloodied, broken—and then at his own claws. His eyes well with something new—grief. He closes them, exhales, and lowers his tail.

He lets Driscoll go. The knight falls to the ground, sobbing and clutching his ruined face.

Soon, the Forever Knight stronghold is surrounded by Plumber ships. Knights are being taken into custody, and the freed alien prisoners—many of them disoriented and overwhelmed—are being helped onto transport vessels.

Izuku: Everyone get out okay?

All Might: Thanks to you guys.

Aizawa: The Plumbers will be sure to escort everyone back home to their families. And with their base of operations destroyed, well, it's safe to say the knights will be out of business for a good while.

Zsef stands to the side, watching as his fellow prisoners are reunited with their people. He stays back—alone, silent. His face is hollow.

Zsef: I don't know where to go. My world is gone. My family… my future... it all died in that cell. What’s left for me now?

Izuku walks over and gently places a hand on his arm.

Izuku: Your family will always be watching over you. And now, you're free. You've got a second chance at life.

Ochako: You’ve got the whole universe ahead of you. Who knows what you’ll find out there?

Zsef looks at them, eyes glimmering with emotion. For the first time in a long time, he lets out a soft breath—not of pain, but peace. He steps onto the transport, joining the others. As the ships disappear into the stars, Izuku stares down the now ruined castle, tense, eyes shadowed. The sound of Bakugou’s voice still echoes in his head. His fists clench.

"RGH!!! KACCHAN! YOU HAVE TO STOP!!!"

"I'LL STOP WHEN I'M GOOD AND DEAD!!!"

The dim glow of the screen casts flickering shadows over the room. A news report blares footage of Bakugou's latest rampage—craters torn into city streets, wrecked vehicles, panicked civilians fleeing. Izuku sits hunched on the couch, fists clenched so tight his knuckles are white. Ochako sits beside him, quiet at first, glancing between the footage and her best friend. His jaw is tight, his eyes dark with guilt and fury.

Ochako: Hey, we'll stop him. Next time, for sure.

Izuku: It's all my fault, Ochako. Kacchan's still out there because of me.

Ochako: No, Deku! This isn't on you!

Izuku: Yes it is!

Ochako: I'm not gonna let you beat yourself up about this!

Izuku: It's my powers he's using, it's my responsibility, and every time he gets away! EVERY TIME! AND HERE I AM LIKE AN IDIOT RISKING MY NECK FOR SOME... MUTANT ASSHOLE WHO DOESN'T EVEN APPRECIATE IT!

With a guttural yell, he kicks over a nearby chair, the crash jarring against the quiet hum of the monitor.

Ochako: Deku—STOP! Breathe—!

Izuku: You think if I turn him back into a human, he’ll thank me? That he’ll say “great job, Deku, I owe you one”? He’ll spit in my face the second I save him. Like none of this ever happened! The minute I cure him, he's gonna go back to being the same piece of shit he always was like I didn't save his life!

Ochako: I know...

Izuku: UGH! Shit man, what am I even fighting for?! I'm trying so hard to save this jerk and for what?! All the pros just wanna kill him anyway... maybe I should just let them.

Ochako gets scared and grabs Izuku's hand.

Ochako: Don't say things like that.

Izuku: I could end it.

He quickly activates the Omnitrix and dials up Alien X, showing Ochako the hologram.

Izuku: Right now. One move.

Ochako: That's not you. You're better than that, Deku. I know things are hard. I know what Bakugou did to you before. And I know a part of you wants to put him in his place, but this... this is bigger than him. It's about saving everyone, even if he never says thank you.

Izuku looks away, torn.

Ochako: I've watched you fight through impossible odds. I've seen you grow into someone I'm proud to call my best friend. And I'm not letting you throw all that away.

Izuku: ...What if I can't stop him? What if our only option is...

Ochako: Hey, look at me. It's not going to come to that. Every fight we have against Bakugou gets us one step closer to curing him. You'll save him, I know you will.

Izuku: How do you know?

She smiles, a soft, unwavering confidence in her voice

Ochako: Because you're Deku. You're the Deku who can do it. The Deku who never gives up, no matter the odds. The Deku who's put his life on the line time and time again to save everyone with a smile. If anyone can save Bakugou, I know it's you!

Izuku's tension begins to ease. He looks at her, then back at the screen showing Bakugou's rampage.

"She's right. No matter what happens, I'm not going to give up on saving him. You better get ready, Kacchan, cause next time we ARE finishing things. Play time's officially over."

Chapter Text

The sky glows orange as fire devours a high-rise somewhere in Hosu. Sirens wail as panicked civilians flee down smoke-filled streets. Flames lick at the ceiling. Crumbling walls groan under the heat. Heroes rush in and out, coordinating the evacuation.

Backdraft and several other water and firefighting heroes start hosing down the flames, while Manual and a few others are moving the people. 

Backdraft: Keep the pressure on that east wall—don't let it spread!

Manual: Everyone keep moving! This area's not safe!

Suddenly, a violent CRASH echoes through the street. Glass explodes from the side of the building as Swampfire is hurled through it like a missile, slamming into a parked car and tumbling across the pavement.

Swampfire: ARGH!!!

The methanosian groans, pushing himself up to a knee. Emerging from the smoke above, a hulking, snarling figure lands with a THUD. It's Mutated Bakugou, his twisted form radiating heat and rage.

Swampfire: *panting* I'm getting so sick of this.

Bakugou: You just don't know when to quit, do ya?

Swampfire snarls, raises his hands—flames burst forward in a torrent, but they wash harmlessly off Bakugou's mutated skin.

Swampfire: That usually works...

Bakugou smirks as he vanishes in a blur using XLR8's speed and reappears with a brutal clothesline, sending Swampfire through the building. The Methanosian smashes through walls, furniture, beams until he crumples against a cracked foundation.

Swampfire: Ugh...

Bakugou grins as he walks through the wreckage, looming over Swampfire menacingly. 

Bakugou: Running outta monsters to try and fight me with, Deku!

Swampfire then looks around him, seeing the building is in no condition for any more collateral damage. He groans, weakly raises his hand toward the Omnitrix.

"WATERHAZARD!!!"

He transforms just in time to block Bakugou's fist with his armored faceplate. Bakugou snarls—and then SLAMS into him. They crash through the floor, plummeting level by level, smashing beams and walls on the way down. A cloud of dust settles. Rubble shifts. Waterhazard lies motionless under the debris. Bakugou looms over him, panting, his fists smoking.

Bakugou grins at his fore, getting ready to finish it. Suddenly—he hears sirens. Lights flash outside. The pro heroes are closing in. He scowls, then ROARS and rockets upward through the ceiling, bursting into the night sky and vanishing. Once he's gone, Waterhazard's faceplate slides open. He gasps for breath and shoves a beam off his chest.

Waterhazard: Phew. It's a good thing this shell is pretty much invulnerable.

He forces himself to his feet, limping through the wreckage as more heroes arrive.

Waterhazard: *to a firefighter* Let's get the rest of these people out before this place comes down.

As he helps lift a civilian, the flames reflect in his eyes—not just from the fire, but from the fight still burning inside him. 

The first rays of dawn begin to stretch across the sky as Izuku stumbles into the Plumber base, his eyes heavy with exhaustion. Dirt clings to his suit, and his shoulders sag under the weight of another fruitless night. Across the room, Ochako sits hunched over her spellbook, a soft light glowing from the pages.

Ochako: Hey.

Izuku: Hey...

Ochako: No luck?

Izuku gives a small shake of his head, the gesture sharp with frustration. Ochako closes the book, her eyes softening as she approaches.

Ochako: You need to rest. You've been running nonstop for days. Let the Plumbers and I handle recon for a bit, alright?

Izuku: ...Yeah. Alright. Thanks, 'Chako. I'll grab a quick nap... then head back out.

He drops onto a cot, but sleep won't come easy. For over a month now, they've tried everything—strategy, power, reason—to stop Bakugou without killing him. And every time, they've failed. Even All Might has kept his distance, fearing what a direct clash might do—to Bakugou, and to himself. 

In nearly every battle they've had, Bakugou has come out on top one way or another. Even Izuku's strongest physical aliens and Ultimate aliens couldn't stop him. For every alien he used, Bakugou has managed to counter one way or another.

"Kacchan's always reckless and aggressive but now... he's way too dangerous. All my powers in the palm of his hands and in that mental state... I can't keep failing. There has to be something in my arsenal that can bring him down."

He turns over, eyes burning despite his fatigue. It takes nearly an hour before sleep finally pulls him under.

A few hours later... Deku's Omni-comlink crackles to life. Izuku jolts upright.

BZZT—BZZT!

Ochako: *on coms* Deku!

Izuku: Ochako? What's up, where are you?

Ochako: We found Bakugou! Downtown. Sending you the coordinates now.

Izuku: Got it. Don't engage—wait for me!

Ochako: ...A little late for that.

Izuku: What do you mean?

Ochako: He's already taken out the pros. Death Arms, Gunhead, Gran Torino—they're down!

Izuku's eyes widen. He springs to his feet and bolts for the exit, slamming his hand onto the Omnitrix as he runs.

His eyes widen as he jumps up from his seat and races out of the Plumber Base. Once he reaches the top he runs out and transforms quickly.

"JETRAY!!!"

By the time Jetray is on the scene, the city's a warzone. Craters scar the pavement. Buildings burn. Civilians scatter in panic. Ochako and Aizawa stand in the middle of it, shielding bystanders behind a glowing barrier as Bakugou—now a twisted fusion of multiple alien powers—pummels the forcefield with relentless fury.

Bakugou: Come out and fight, damn cowards!

Suddenly, a cluster of diamond shards slam into his face. He stumbles, growling, and turns—just in time for Diamondhead to land a crushing punch that sends him flying.

Ochako: Deku!

Diamondhead: You two alright?

Ochako: We're holding on. But the pros are down!

Diamondhead's eyes flick toward the unconscious heroes scattered nearby.

Diamondhead: Get them out of here. I'll handle Kacchan.

Bakugou growls and charges, his mutated limbs shifting. He slams Diamondhead with a Wildmutt-Rath hybrid arm, launching him into a metal pole.

Bakugou: You are one sorry sight, Rockhead!

Diamondhead: That's Diamondhead. And speaking of sorry sights, have you looked in the mirror lately?

Bakugou: It's payback time for turning me into this freak!

Diamondhead: You were always a freak. It's just that now the ugly's also on the outside.

Bakugou: Diss me all you want. I'm still ten times better than you! I've got all your powers, plus my own! YOU CAN'T STOP ME!!!

Bakugou unleashes a hail of jagged crystal projectiles. Diamondhead blocks most, shattering others mid-air.

Diamondhead: Too bad every one of yours is only a tenth as powerful as mine!

They clash again, their blows leveling the block. Blades, beams, fists—it's a whirlwind of chaos. Diamondhead lands several good hits, but Bakugou keeps coming, faster, stronger, more unhinged. Diamondhead and Bakugou then come to a standoff, trying to push the other back.

Bakugou: You're dead for turnin' me into this!

Diamondhead: I didn't turn you into this! I'm trying to help you! Why won't you let me?!

Bakugou: I don't need your help!

He delivers a brutal four-arm gut punch, then blasts Diamondhead's face with acidic goop. Blinded, the hero staggers. Bakugou ignites his Heatblast arm and drives it into Diamondhead's chest, fracturing his crystalline armor.

Diamondhead: Ghh—!

The Omnitrix blinks red and times out. Izuku collapses, unconscious and vulnerable.

Bakugou: Hehehe...

He steps forward to finish him—only to be engulfed in a column of fire.

Bakugou: GAAAH! WHAT THE HELL?!

Suddenly, Endeavor steps through the smoke, flames curling from his fists. Bakugou grins wildly at the challenge. 

Bakugou: Number Two, huh? You're just in time.

Endeavor: Last warning. Drop the kid.

Bakugou drops Izuku and blitzes forward with XLR8 speed. He decks Endeavor with a diamond-arm punch that sends him crashing into a wall. Endeavor recovers fast, retaliating with a jet of flame, only for Bakugou to absorb it with his Heatblast arm and retaliate with a blast of chromastone energy.

Bakugou: Fire won't save you, old man!

Chunks of pavement fly as Bakugou spits Upchuck bombs, shaking the ground with Humungousaur's strength. Endeavor stumbles—Bakugou phases through him with Big Chill's power, freezing him mid-motion.

Endeavor: Ngh...!

Bakugou: Looks like someone's got cold feet!

He shapes his diamond arm into a blade and charges—only to be blasted back by a barrage of pink energy.

Ochako: GET AWAY FROM HIM!!

Bakugou: YOU...!

She dodges his flame strike, counters with twin energy beams that wrap around his arms.

Ochako: Adficio potentia!

Bakugou: Rgh—!

He yanks the beams, dragging her forward. As she slides, Endeavor melts the ice with a surge of heat and slams into Bakugou.

Endeavor: FLASH FIRE FIST—JET BURN!!!

His flaming punch drives Bakugou through a wall, but the boy barely flinches. Roaring, he counterattacks. Endeavor ducks, weaves, and tackles him to the ground.

Bakugou: GET OFF!

Endeavor: Sorry, kid.

He pulls a syringe-like device from his belt and pops the needle, raising it toward Bakugou's neck. Ochako sees this and realizes what he's about to do.

Ochako: WAIT—NO!!!

She lashes out with her energy, snatching the syringe and pulling Endeavor back.

Endeavor: URK! Why you-!!!

Bakugou: Next time, Deku!

Bakugou takes the opportunity to vanish in a burst of Necrofriggian mist before taking off into the sky. Izuku stirs, eyes fluttering open as Endeavor looms over him.

Endeavor: We need to talk...

Izuku and Ochako sit before a gathered group of pro heroes in a private office. All Might and Aizawa are present, silent but tense. The room hums with restrained energy.

Endeavor: I'm sure you're aware of why you're here.

Izuku: Gonna take a wild guess and say Kacchan.

Endeavor: Then you must already know what has to be done.

Izuku: You can't just put him down!

Kamui Woods: I hate it too, kid. But at the rate he's going, he's not leaving us much of a choice.

He taps at a nearby console. A holographic screen comes to life, showing brutal footage—Bakugou tearing through heroes, demolishing structures, leaving destruction in his wake.

Endeavor: In one month, Bakugou's caused more damage than most villains manage in a career. And this... this is every pro who's gone up against him.

Names flash across the screen—high-ranking heroes, most marked with "Critical Injury" or "Hospitalized."

Endeavor: See the pattern?

Izuku: Those are all higher ranked pro heroes... he's going after the strongest of them.

Ochako: Why would he do that?

Izuku: To prove he's the best.

Endeavor: And if we can't stop him... then putting him down may be the only responsible option.

Izuku: Because of something he can't control, you're ready to kill him?! And how's that fair to him?

Mt. Lady: Nobody's saying it is.

Izuku: Then stop trying to kill him and let me handle this!

Endeavor: You've fought him more than anyone. And lost. If anyone should know he's too far gone... it's you.

Mt. Lady: We know you wanna help your friend and all, but... this might be the only way. For the people's safety and his. This is bigger than any of us.

Izuku lowers his head, then lifts it with resolve. 

Izuku: ...Give me one more chance. 

Endeavor: Hm?

All Might: Young Midoriya?

Izuku: Just one day. Give me 24 hours. If I can't reach him—if I fail—then do what you have to.

A heavy silence settles. All eyes turn to Endeavor.

Endeavor:...Fine. One shot. 24 hours. But if you fail—

Izuku: I won't.

Endeavor: If you do... I finish it. No hesitation.

Deku nods, extending his hand.

Izuku: Do we have a deal?

Endeavor stares at the hand. Then, reluctantly, he grips it.

The sun begins to set as Izuku and Ochako walk in silence before she breaks it.

Ochako: Alright. Twenty-four hours. You have a plan?

Deku begins thinking out loud as they walk. 

Izuku:  Kacchan has access to every single one of my aliens' powers. I've analyzed each and every one of them more than anybody else... and I know how Kacchan fights. Each of his powers from every individual alien is only one tenth as strong as me in the full form...

Ochako: Well yeah, but you can only be one alien at a time. He can use all of your powers at once.

Izuku stops in his tracks, eyes going wide. 

Izuku: He can use them all at once... Yeah... YEAH!!! OCHAKO YOU'RE A GENIUS!!!

Ochako: *smirks* Of course I am... what am I a genius about though, exactly?

Izuku: I can't beat Kacchan with one alien. I'll need to fight him with all of them—simultaneously. And I know exactly how to make that happen!

Ochako beams at the spark of confidence in her friend.

Ochako: So what do we do?

Izuku: If this is gonna work, we'll need all the help we can get. Go get Iida, Todoroki, Kirishima, and Rex. Meet me at Mr. Smoothies.

Ochako: And you?

Izuku:  I'm gonna cash in a favor.

The two of them do their secret handshake and go their separate ways. Meanwhile, in a dimly lit office, All For One sits alone, bathed in the cold glow of multiple monitors replaying footage of Bakugou's rampage. Explosions, shattered buildings, screaming civilians—the chaos unfolds again and again, intercut with headlines questioning the heroes' ability to protect the public.

A smirk creeps across All For One's face. Suddenly, the door opens.

Dr. Ujiko: Forgive the intrusion, Master... but it's ready.

He steps forward, holding a sleek, ominous collar-like device.

Dr. Ujiko: Also, our intel confirms it—Midoriya intends to face Bakugou soon. All Might as well. They're planning to end this tomorrow night.

All For One: Perfect. Timing couldn't be better. And Tomura?

Dr. Ujiko: The transplant is underway. His body is responding even better than we predicted.

All For One rises, folding his hands behind his back. Everything is falling into place. He turns to the main monitor—All Might's face stares back at him.

With one swift punch, All For One shatters the screen.

All for One: When this is over, the number one hero will be no more. And all of the power will be as it should be... Within my grasp. 

Several hours later... Izuku, Ochako, Iida, Todoroki, Kirishima, Rex, and Bobo all sit around a booth at Mr. Smoothie's. The weight of what's ahead hangs in the air.

Izuku: Thanks for coming you guys. I'm guessin' you already know why we're here?

Kirishima: Yeah... this is our last shot to save Bakugou.

Ochako: Right now, we know he's been targeting top-ranked heroes in the area, trying to prove he's the strongest there is. 

Izuku: And we're going to use that. 

Todoroki: How?

Izuku: Think about it. The strongest hero in the world is our teacher.

Iida: Midoriya! Don't tell me you want to use All Might as bait!

Izuku: That's exactly what we're gonna do. All Might's going to be the bait. Once Bakugou takes it, you and Kirishima pull him out. The rest of us? We do everything we can to wear Bakugou down. Nothing lethal. Just enough to give me an opening.

Todoroki: Assuming we can even manage that. He's not exactly... soft.

Kirishima: Bro, you sure this is gonna work? I mean no offense, but you've fought him before and got your butt kicked. What's gonna be different this time?

"Because this time he won't be holding back."

Everyone turns as Melissa Shield approaches their table.

Melissa: Sorry I'm late, Uncle All Might got me the first flight here as soon as you called.

Kirishima: Hey, aren't you the girl from I-Island?

Ochako: Melissa?! What're you doing here?

Melissa: Midoriya called me. Got me up to speed with the Bakugou situation.

Izuku: Can you do it?

Melissa walks over to Izuku and studies the Omnitrix on his wrist.

Melissa: With my lab? Absolutely. Without it... it'll take time. But I can make it work.

Izuku: Then we don't have a second to lose.

Later that night... Every screen in Japan flickers to a live broadcast. All Might stands before the camera, larger than life, beaming with his iconic smile.

"HAHAHA! I AM HERE! AND I HAVE A MESSAGE FOR YOUNG KATSUKI BAKUGOU! IF YOU TRULY WISH TO PROVE YOU'RE THE STRONGEST... THEN MEET ME AT THE OLD VILLAIN WAREHOUSE TOMORROW NIGHT! I'LL BE WAITING!!!"

All Might laughs heartily, the transmission cutting out. The scene cuts to Bakugou, watching the message play on a cracked monitor in some ruined building. He grins.

Bakugou: Challenge accepted, Old Man.

The ruins of the League of Villains' former hideout loom under the moonlight. In the center stands All Might, statuesque and calm, waiting. Hidden in the shadows and nearby vantage points, Izuku, Ochako, Rex, Todoroki, Kirishima, Iida, Aizawa, Thirteen, and a squad of Pro Heroes and Plumbers wait silently, tense and ready.

Izuku: Alright. He'll be here any minute. Comms check—everyone in position? 

Kirishima: *on radio* Loud and clear, bro. Ready to move.

Rex: *on radio* We're ready, amigo!

Todoroki: *on radio* Hope this works. Otherwise my father-

Izuku: I know... Alright, everyone get ready.

Iida: *on radio* Copy. Standing by.

Izuku turns his attention back to Melissa as she fine-tunes the device on the Omnitrix. She works quickly with a small toolkit beside Izuku, attaching a device to the watch.

Melissa: This bypass tool should punch through the Omnitrix's security—grant you full Master Control again. But it'll take a little time. Until then, no transforming.

Izuku: Then One For All is all I've got... and it'll have to be enough. We can't stop him otherwise.

Footsteps approach as Ochako walks up quietly.

Ochako: Alright, everybody's in position. You ready to do this?

Izuku keeps his eyes on the Omnitrix being decoded. His hands tremble slightly.

Ochako: Deku?

Izuku: I'm... fine...

Ochako: This is gonna work Deku.

Izuku: I sure hope so.

Ochako: Hey, c'mere.

She pulls him into a comforting hug. He hesitates, then hugs her back tightly.

Izuku: Thanks, Ochako. I needed that.

Suddnely, a sharp beeping interrupts the moment as the Omnitrix glows red.

Omnitrix: Warning. Severe genetic damage detected.

Izuku: He's here. *over coms* Everyone, eyes up. Bakugou's inbound. Move into final positions!

Moments later, a sonic boom rips through the air as Bakugou streaks through the sky, landing hard several yards from All Might with a fiery explosion at his feet.

All Might: Haha! Young Bakugou! Right on schedule.

Bakugou: You called me out, Old Man. Guess I'll give you the fight you're begging for.

Al Might: It doesn't have to be this way, kid. One last chance to end this peacefully. 

Bakugou: Don't worry—I'm not gonna kill you. I'm just gonna end your career with a bang. I'LL PUT YOU INTO EARLY RETIREMENT!!!

He lunges forward, fists blazing and the trap is set.

TO BE CONTINUED...

Bakugou: Don't worry—I'm not gonna kill you. I'm just gonna end your career with a bang. I'LL PUT YOU INTO EARLY RETIREMENT!!!

He lunges forward, fists blazing and the trap is set. He launches forward, explosions ripping from his palms, eyes wild with fury. He rockets toward All Might with XLR8's blinding speed—only to strike nothing but air. In the blink of an eye, All Might reappears behind him, cape rippling.

"He's so fast! Faster than me?!"

All Might: I must apologize to you, Young Bakugou, but the truth is, I have no intention of fighting you today!

Bakugou: What's that?! Backin' down already?

Ochako: That's my cue!

She puts her hands together as her eyes glow a burning pink and slams them both on the ground.

Ochako: Hatrium Securitatum!

A magic circle ignites beneath them, bathing the battlefield in blinding pink light. A massive energy dome forms, trapping Bakugou inside as Izuku, Ochako, Todoroki, and Rex dive in from above like falling stars.

Izuku: You're not getting away this time!

Todoroki: Sorry about this Bakugou, but it's for your own good!

Rex activates the Smack Hands and Todoroki fires a freezing blast. Bakugou retaliates, crystal arm clashing with Rex's fists, a BOOM echoing across the field. Izuku follows up, activating his Full Cowling.

Deku: DETROIT SMASH!!!

His punch detonates into a cyclone of wind, sending Bakugou flying. Rex soars above with the Boogie Pack and slashes him midair with his Big Fat Sword. Bakugou crashes to the ground, barely winded.

Bakugou: Hehe... this was your plan? Ganging up on me? Pretty damn desperate!

With a roar, he punches the ground, causing Swampfire vines erupt violently, lashing out. Ochako protects them with an energy field as Rex tears through the tangle, forming his sword into buzzsaw.

Todoroki: Keep him busy so I can freeze him.

Izuku and Ochako: On it!

The two of them power up, Deku using Full Cowl and Ochako charging up with energy. They close in on Bakugou, Deku hitting him with a Texas Smash, followed by a flying kick to the face. Ochako then follows up, engulfing her fists in burning pink energy as she rushes at Bakugou hitting him with powerful punches. 

The two of them keep double-teaming the mutant while Todoroki seizes an opening to freeze up his body. The ice begins to take hold—but cracks instantly as Bakugou shatters it, roaring, tail whipping. He slams the ground with Humungousaur's strength, the shockwave hurling Rex and Ochako back. 

Deku dives in again, clashing with his Diamondhead arm. Todoroki glides beneath, freezing him solid this time. But Bakugou's glowing red eyes pierce through the frost.

Bakugou: YOU'RE ALL REALLY STARTING TO PISS ME OFF!!!

The ice explodes outward, but before he can attack again, Ochako fires rapid energy blasts to slow him, Rex re-engages with sword in hand. He and Bakugou enter close combat, as he forms his own sword with his Diamondhead arm. The two of the come to a clash and begin to duel, steel-on-crystal. While Bakugou is preoccupied with Rex, Ochako puts her hands together and charges up a blast.

Ochako: Hey Blasty! Remeber this trick from the sports festival?!

Pink lighting and energy gathers in her hands as she channels all of her power into a concussive burst.

Ochako: Merchucus Verditis!!!

She thrusts her arms forward and fires a humungous beam of energy and lightning at the mutant. The titanic beam crashes into Bakugou. He tries to shield with Chromastone shards—but the blast tears through, hurling him across the field, smoking. The heroes regroup, panting.

Ochako: How we doing on unlocking Master Control?

Izuku looks down at the watch to see it still spinning and decoding.

Izuku: Gotta hold him back a little longer!

Rex: Not sure how much longer we have, amigo. We've thrown everything at him and he's still getting back up!

Music Insert:

As Bakugou gets back up and the four of them get ready to fight once more, suddenly... the temperature drops. The air twists. A low hum fills the space... and the light inside Ochako's barrier flickers. Then, reality rips as a purple vortex tears open inside the energy field, crackling with malice.

Rex: Was this part of the plan?

Todoroki: Midoriya... what is this?

Izuku: No... no, it can't be... I know that portal...

More warp gates erupt across the dome, bypassing Ochako's enchantment with ease. The air turns heavy and oppressive.

Ochako: Deku, what's happening?

Kirishima: *on coms* Midoriya, we've got a situation—major party crashers!

Aizawa: All units—Code Purple.

Out of the swirling void, they step. Toga. Spinner. Dabi. Mr. Compress. Twice. Charmcaster. And finally... Shigaraki.

Shigaraki: Sorry to drop in uninvited... but we'll be taking the boy now.

Ochako: The League of Villains?! NOW?!

Music Insert:

Then... the sky darkens. A final portal opens above them. A voice—smooth, cold, ancient—echoes across the battlefield.

"My my... what a lovely mess you've made. It's been too long... Symbol of Peace."

All Might's face goes pale.

All Might: No... not him. Anyone but him.

Descending from the heavens like death itself—All For One.

Izuku: Oh man...

All For One raises a hand and commands his minions. 

All For One: Bring me the boy. Crush the rest. But All Might... is mine.

At his command, The battlefield erupts into chaos. Dabi and Spinner leap at Rex and Todoroki. Charmcaster and Toga close in on Ochako. 

Charmcaster: Look what we have here! Little goody-two shoes thinks she's all that now!

Toga: Hi Ochako! I missed you! Let's play!

Ochako: I don't have time for either of you!

Her eyes blaze pink. She fires an optic blast. Charmcaster dodges and retaliates:

Charmcaster: Berdi Mordo Nata!

Ochako blocks with a glowing shield.

Ochako: Contego!

The shield then absorbs the energy and fires it back, blasting Charmcaster off her feet.

Ochako: I've picked up a few tricks since last time.

Toga suddenly lunges from behind, knives flashing. Ochako reacts just in time, blocking the attack.

Toga: C'mon Ochako! We're friends so lie down and bleed for me!

Ochako: Ngh! You need medicine!

Elsewhere, Iida and Kirishima try to slink away from the fight, wanting to keep All Might out of it at all costs. However, Shigaraki, Spinner, and Compress block their path.

Shigaraki: Leaving so soon?

Iida and Kirishima ready themselves—but All Might steps forward.

All Might: No. Stand down.

Kirishima: What?! But—!

All Might: GO. Midoriya needs you more.

He punches the ground, sending villains flying with one blow.

All Might: GO!!!

Iida and Kirishima sprint off to aid their comrades. All Might watches them vanish—then turns to face his oldest enemy. Gran Torino appears beside him.

Gran Torino: You know it's a trap, don't you?

All Might: Not much choice now. I've been running from this for too long. I won't let anybody else pay for my mistakes.

Gran Torino: *sigh* Then let's take this punk down for good!

They charge together toward the fight that would decide everything. Amid the chaos of the battlefield, Izuku Midoriya tore through smoke and rubble, heart pounding and mind racing. His original plan was falling apart. He hadn’t expected the League to return this soon—let alone him. All For One’s presence changed everything. The stakes had skyrocketed.

Deku glanced down at the Omnitrix on his wrist. It was still spinning, still decoding—still not ready. He muttered, frustration etched across his face.

Izuku: Come on…

A blur of movement whooshed past and suddenly Bakugou was in front of him, with a sinister grin on his face. Before Izuku could react, a wicked right hook slammed into his jaw, sending him skidding across the dirt. He groaned, pushing himself up just in time to meet Bakugou’s menacing gaze.

Bakugou: Nowhere left to run, Deku!

Bakugou lunged again. This time, Izuku dodged, leaping into the air with practiced grace, green electricity snapping to life around his limbs.

Izuku: One For All: Full Cowling… 50%!

He rocketed forward, fists blazing, landing a flurry of smashes against Bakugou’s armored body. Every blow echoed with force, but the damage was negligible. Bakugou’s alien-enhanced hide held strong. Izuku gritted his teeth in frustration. 

Izuku: Turn it up. 75%!

With a surge of power, he struck harder, driving an uppercut into Bakugou’s chin. Blood dripped from his rival’s nose. Bakugou wiped it away and grinned.

Bakugou: Heh. Gotta say, Deku… You’ve grown a pair. I almost respect that.

But Izuku didn’t stop. He kept moving, faster, sharper, darting in and out with precision strikes, trying to find an opening. He knew brute force alone wouldn't bring Bakugou down. Not this version of him. Not with all his alien DNA. But he just needed a little more time.

Bakugou: What’s wrong? No fancy transformations? Decided to die like a man after all this time?

Deku didn’t answer. He slammed a smash into Bakugou’s chest—minimal effect. Still not enough.

Izuku: 80%… 90%!

Bakugou: This… This is what I wanted back then. We could've been proper rivals, duking it out to see which Not that crybaby loser who just stared while I tore him down. Now you’re actually worth fighting! 

Izuku’s jaw clenched. The memories of their past—every insult, every blow—flashed in his mind. But he wasn’t that kid anymore. He planted his feet.

Izuku: No holding back. 100%!!!

Green lightning exploded around him as he vanished from view. In an instant, he reappeared in front of Bakugou, channeling every ounce of strength into a single, devastating attack.

Izuku: DELAWARE… DETROOOOOOOOIIIIT… SMAAAAAAAAASH!!!

His fist connected—square in the gut. Bakugou’s eyes bulged as the force hurled him back, crashing him through the battlefield and slamming him into the energy barrier with a violent BOOM! Izuku collapsed to one knee, breathing hard, his arm trembling and scorched from the force. He looked at his knuckles—bruised, steaming.

He took a second to catch his breath, but it didn't last. Using XLR8-speed again, Bakugou was on him before he could react, grabbing Izuku and launching them both high into the air.

Izuku: ACK—!

Bakugou: Hahahaha! That was a hell of a punch, Deku! Almost felt that one!

Izuku: Ngh… Kacchan… Don’t do this…

Bakugou: I’ll admit it… gonna miss beating the crap outta you.

His crystal arm morphed into a jagged blade. He raised it, eyes wild with intent.

Bakugou: Any last words?

Izuku’s breath caught. Suddenly, he heard a click. Then a beep and a rising whir. His eyes widened as the Omnitrix erupted with green light, the spinning core locking in place. A holographic chain appeared, twisting into a DNA helix.

"Omnitrix firewalls breached. Master Control access granted."

Bakugou’s smirk faltered. Izuku met his eyes and smiled.

Izuku: Yeah. Just one.

The Omnitrix activated on its own as a bright green flash engulfed him.

"HUMUNGOUSAUR!!!"

In a split-second, Deku transformed into the towering Vaxasaurian titan. Before Bakugou could react, Humungousaur roared and brought both fists down like hammers, smashing Bakugou into the dirt with a bone-rattling quake.

A crater exploded beneath the impact with a CRASH! Humungousaur landed, shaking the earth. As the dust settled, Izuku shrank back to human form, panting, grinning at the familiar sight of the Master Control interface glowing on his wrist.

Izuku: Yeah… Glad to have you back, buddy.

Bakugou staggered to his feet, bloodied but grinning through cracked lips.

Bakugou: There it is. That busted ass power of yours. Finally deciding to stop holding back? Doesn't matter either way! YOU'RE DEAD DEKU!!!

Music Insert:

Izuku’s grin sharpened. He slammed the watch, transforming once more in a green flash into his Kinnecerlin form—XLR8’s sleek body humming with power. The Omnitrix core pulsed with radiant energy, blending seamlessly with Full Cowling. Lightning and Omni-energy crackled in unison.

He slid the face shield down over his eyes.

XLR8: Let's do this!

In the blink of an eye, he vanished. A sonic boom shattered the air as XLR8 burst forward, ripping through space like a green comet, slamming into Bakugou with blistering speed. The impact knocked the mutant off his feet, and XLR8 was already gone before Bakugou could react. The Kinneceleran reappeared again and again, striking from every angle, trapping him in a swirling storm of blue streaks and electric trails.

Bakugou growled, trying to match his speed, but even with XLR8's DNA in his system, it was like trying to catch lightning with bare hands. Deku wasn’t just fast—he was unstoppable. XLR8 zipped backward, skidding across rubble before transforming again. A fiery burst erupted around him as Heatblast emerged from the inferno, molten veins glowing beneath volcanic skin. Omni-energy laced his flames as he thrust his arms forward. 

Heatblast: BURN UP!!!

Twin geysers of scorching fire screamed toward Bakugou. He raised a crystalline Diamondhead arm to shield himself, but as he braced, he didn’t see the next move. A red blur shot down from above as Fourarms roared through the smoke and slugged Bakugou in the gut, the sheer impact cratering the earth beneath them.

Fourarms: If this is what it takes to knock sense into you—then so be it!!

Without pause, he hammered Bakugou with a brutal barrage. Each punch was a seismic event, rattling windows blocks away. Bakugou blocked where he could, but Fourarms was relentless, battering him left and right. One final colossal uppercut sent him skidding across the battlefield.

Fourarms: HYAAAAHH!!!

Bakugou coughed, clutching his chest, his breath ragged—but he stood tall, bloodied and enraged.

Bakugou: So you got another cheap power up! I don't know how the hell you're changing so fast, but it doesn't matter CAUSE I'M THROUGH WITH YOU!!!

Fourarms: KHOROS SMASH!!!

They clashed fists, the force rippling outward in a thunderous shockwave. But in the next beat, Deku’s form shrunk as he became Grey Matter, leaping across Bakugou’s shoulder and crawling behind his neck. Bakugou flailed, striking himself as he tried to grab the slippery, minuscule alien.

With a flash, Deku became Goop, splattering over Bakugou like a living net, trying to bind him down. But the mutant roared and tore Goop apart, flinging the gooey mass across the battlefield. Goop quickly reformed—just in time to dodge a wave of ice from Bakugou’s Big Chill form. Swampfire replaced Goop in an instant, fire roaring from his palms to melt the ice midair. With a flick of his hand, he hurled mossy sludge at Bakugou, blinding him.

Swampfire: Here's mud in your eye!

Bakugou staggered, blinded—until flames engulfed him. Swampfire unleashed flamethrowers at full blast—only to be knocked back by a Jetray neuroblast, his limbs torn through before regenerating. Bakugou hurled a boulder at him, smashing him into the dirt. Snarling, he dashed forward, slashing at the Methanosian with Rath’s claws—but he dodged, ignited, and transformed again.

Terraspin took his place, spinning up a power vortex that yanked Bakugou in. The mutant stabbed a Diamondhead arm into the earth to stabalize himself and fired another neuros the spinning turtle, knocking him from the air. As Bakugou pounced, Terraspin retreated into his shell, tanking blow after blow with ease.

Bakugou: QUIT HIDING AND FIGHT ME!!

Terraspin shimmered and vanished as Big Chill phased out of the ground, intangible. He froze Bakugou’s limbs mid-attack, then shifted again as Blitzwolfer howled, unleashing a sonic storm that staggered Bakugou. While his ears rang, Blitzwolfer pounced, slashing with claws and launching him through a shattered building.

Blitzwolfer: That got your attention, huh?

With a flash of green, he became Echo Echo, duplicating in a blink.

Echo Echo: ECHO CHAMBER!!!

They unleashed a symphony of sound, trapping Bakugou in a relentless, disorienting wave of sonic chaos. Bakugou screamed and slammed his fists into the ground, channeling Humungousaur’s strength. The Echo Echoes were thrown aside like paper dolls. One by one, he crushed them—until only one remained.

Bakugou: I told you before!, I've got all your powers! We could be here all damn night, and that wouldn't change a thing! You can't stop me! I know everything you're gonna do before you even do it! Anything you pull, I can one up!

Music Insert:

The Sonorosian smirked.

Echo Echo: Then let’s skip to the good part.

He slapped the Omnitrix as four metal spikes jutted from the sides, glowing with power as green light surged. His form stretched and evolved, gleaming in black and blue, sonic discs embedded all over his body.

"ULTIMATE ECHO ECHO!!!"

Bakugou flinched, taken aback.

Bakugou: …Oh crap. I forgot about those.

With a wave of his arm, Ult. Echo Echo let loose a deafening Sonic Scream, launching Bakugou back into a wall. The amalgam shook off the attack, still standing his ground. 

Bakugou: Rgh! You are really starting to bug me!

Ult. Echo Echo: I'm sorry about that, but I can't let you hurt anyone else.

Bakugou burst out of the rubble, firing every weapon in his arsenal—lasers, lightning, crystal spikes, and flame geysers—but Ult. Echo Echo dodged it all in the sky, retaliating with precision-guided Sonic Discs. The discs spun around Bakugou, firing sound blasts in synchronized bursts. He howled, swinging at them in fury.

Bakugou: GRAH!!! FUCK OFF!!!

Bakugou kept swatting at the discs as they spun around him, blasting him with sonic waves. While he was distracted, Ult. Echo Echo rocketed in, fist crackling, and struck Bakugou with a sonic-charged punch that shattered the sound barrier and cratered the earth below.

Ult. Echo Echo: SONORSIA... SMASH!!!

Ult. Echo Echo hit Bakugou with a powerful smash, causing a power sonic boom as Bakugou hit the dirt hard, creating a massive crater in the ground. Bakugou struggled to get back up, glaring at the evolved Sonorosian staring down at him. He grit his teeth and took off using XLR8's speed and Heatblasts fire, as he charges up massive amounts of energy in his crystals. 

Ult. Echo Echo powered up once more as he dove toward Bakugou. The amalgam shoot the beam as it collided with Ult. Echo Echo who deflected it using his sonic blasts as a shield. He and Bakugou clashed once more before entering close combat, exchanging high speed punches and kicks.

Bakugou wound back another powerful haymaker, but before the attack can connect, Ult. Echo Echo fired off a Sonic blast from his hands, sending the mutant flying and knocking through several nearby buildings. Bakugou refused to stay down, bursting through the rubble and shot through the air after Ult. Echo Echo again. 

Bakugou was throwing everything he has at the evolved Sonorosian, but Ult. Echo Echo could block or dodge everything, before returning the favor 10-fold. He released several more sonic discs at the mutant, making him cry out in agony as he tried to destroy them one by one. While he was preoccupied, the Sonorosian blind sided Bakugou with another devastating sonic haymaker, sending him crashing to the battlefield below. Ult. Echo Echo hovered over the crater as Bakugou rose one final time. 

Bakugou: RRRRRAAAAAAAAAAHHH!!! I'VE HAD IT WITH YOU, DEKU! ALL MY LIFE, YOU WERE JUST IN MY WAY! I WAS THE STRONGEST! NOW I TURN INTO A MONSTER, AND YOU GET A COSMIC CHEAT CODE?! YOU THINK YOU’RE BETTER THAN ME?!

He launched another barrage of crystal shards, one of them cutting through Echo Echo’s barrier.

Ult. Echo Echo: Nnh! I'm not trying to prove anything! I'm trying to help you! All I've ever done is look up to you! I'm trying to save you, Kacchan! Let me cure you!

Bakugou: *sarcastically* Oh, my heart bleeds for you! NOW YOU JUST BLEED!!!

He fired an electric blast from his mouth, but Ult. Echo Echo threw out more discs, one deflecting the blast, the others circling Bakugou again. The mutant then grabbed a steel beam with Upchuck’s tongue, chewed it, and spat a massive projectile at him—only for Ult. Echo Echo to vaporize it with a disc.

Bakugou: Nice! But I've got all your powers! Sooner or later, you're gonna slip up. Run outta juice. And then YOU'RE DEAD!!!

Ult. Echo Echo: Then I'll try to make this as quick and painless as I can!

Bakugou quickly took notice of the several sonic discs hovering around him from that last attack. The discs began charging with an eerie blue light, and before he had a chance to run—

Ult. Echo Echo: SONIC... DOOOOOOOOOOOM!!!

Bakugou: AAAAAAAAAAHHHHHHHHHH!!!

The discs unleashed a synchronized super charge blast, a deafening, all-consuming sonic eruption. Bakugou screamed in absolute agony, collapsing to his knees as the force overwhelmed his nervous system. His limbs spasmed—his eyes rolled back—and finally, the mutated teen dropped into the crater, unconscious.  

The air fell silent. Ult. Echo Echo hovered above, shoulders rising and falling with each breath, staring down at the fallen rival he once called his friend.

Shigaraki: What’s the hesitation?

Ult. Echo Echo turned his head, expression cold and unreadable. Shigaraki stood a short distance away, arms outstretched as if inviting chaos.

Shigaraki: He’s the one who pushed you past your limits, isn’t he? The source of your pain, your doubt. So here’s your big chance, Midoriya. Be the hero. Get your revenge. Save the day.

Ultimate Echo Echo didn’t flinch. Instead, he slowly turned to face Shigaraki, eyes narrowing.

Ult. Echo Echo: That's not what this is about. 

With a flick of his wrist, a sonic disc launched from his arm, curving behind Shigaraki in an instant. It shattered something small and metallic—a hidden control collar.

Shigaraki: Rgh! Why you—!

In a flash of green light, the alien form dissolved. Deku stood where Echo Echo had hovered, his face grim but resolute.

Izuku: Yeah, I figured you’d try something like that. Thought I’d drop my guard so you could strap that thing on me—or worse, him.

Shigaraki scowled, the smirk returning to his cracked lips.

Shigaraki: Still blind to the bigger picture. This world’s already crumbling, Midoriya. It's rotten to the core, with frauds who deem themselves protectors. The heroes you idolize? They’re frauds. Everything this world is, everything they've built up is corrupt. Those who don't fit in are cast aside like trash. You’ve tasted that betrayal—don’t lie. You know. 

Deku didn't say a word. It was true, he had felt that pain before. The way the world had rejected him for being quirkless, how so many people belittled him and told him his dream of being a hero was a fantasy. Bakugou was especially a culprit of this. He thought back to his fight with Stain and how he'd had a similar philosophy. 

Shigaraki: We could’ve remade everything. All that power in your wrist... wasted on protecting a broken system! 

Izuku: Yeah? And what would you do with that power?

The villain smiled thoughtfully, tapping his chin. 

Shigaraki: Me? Hmm... I'd tear it all down. Bring this planet to it's knees. Destroy EVERYTHING.

Izuku: And that'd be better? Just go and cause pointless destruction.

Shigaraki: Pointless? I have a mission. Everything that I’ve ever known… Everything in this world they built rejected me. So I'll reject them. AND DESTROY ANYONE WHO STANDS IN MY WAY!!

Shigaraki stepped forward, a powerful, menacing aura radiating from him. But in that moment, Deku saw a glimpse of something more: a scared little child, tucked into a ball, hiding from the world. Deku quickly snapped back to reality as he dodged Shigaraki attack as he slammed the ground, causing it to decay. 

Deku slid backwards, wiping his face. He stepped forward, eyes glowing with conviction.

Izuku: I'm sorry. I really am. I don't know what you've been through. And I know this world is unfair. But that doesn’t justify becoming the very monster you claim to hate.

Deku dodges another attack, as Shigaraki's decay grows stronger. His voice drops to a low growl.

Izuku: You talk like you’re better than us, but you’re just feeding your own pain. Making the whole world pay for someone else's mistakes? That isn't justice!

Shigaraki: Justice, vengeance, who cares?! I just want to see it all burn to the ground! And I'll start by destroying you, ONCE AND FOR ALL!!!

As Shigaraki reach out to use Decay, Full Cowling crackling to life around Deku. Lightning arced across his frame, each spark a declaration. He smiled and in a burst of speed, he vanished.

Izuku: SMASH!!

His fist met Shigaraki’s face with brutal force, launching the villain across the shattered field. Shigaraki flipped midair, catching himself with decay-charged fingertips—ready to counter. But Deku was already there, faster than sight. Stronger than before. A blur of green and lightning.

A flurry of strikes followed—too fast to react, too precise to block. Shigaraki stumbled, cracking concrete under his feet, unable to find footing against the relentless storm of Midoriya's resolve.

Shigaraki: Where are you—!?

Shigaraki turned just in time to see Deku appearing behind him, his eyes glowing like twin emeralds, fierce and unwavering.

Deku: DETROIT SMASH!!!

The punch slammed into Shigaraki’s chest, hurling him like a missile into the far wall with a thunderous CRASH! Dust choked the air. Rubble caved in. And for a long moment, nothing moved. Deku exhaled, stepping forward as Shigaraki groaned, barely conscious, bloodied and broken. 

Shigaraki’s hateful gaze faltered—just for a second—before his eyes rolled back and his body slumped to the ground. Deku stood still, his breath steady, his lightning fading. As Deku stared at him, for a moment, he saw that little boy inside of Shigaraki again. 

Deku tried to shake the vision off, before finally turning to Bakugou, who was stirring, blinking up at the sky. Deku walked over and stood above him, the edge of a smile tugging at his lips.

Bakugou: D-Deku... I'm not... done...

Deku then places his Omnitrix arm on Bakugou's chest.

Deku: Sorry, pal. Power trip's over!

Omnitrix: Severe genetic damage detected. Genetic code splicing error. Now attempting to repair.

Bakugou: Wait! Don't-! AAAAAAAAAHHHHHHHH!!!

Without giving him time to finish, the Omnitrix glowed bright green, causing a huge flash of light, as Bakugou lets out one final roar. For a moment, all the chaos stops. Both heroes and villains alike cease fighting to see what just happened. The scene then shows Izuku next to a nonmutated human, Bakugou, as all his friends begin to cheer for them.

Kirishima: He's human again!

Iida: Good work, Midoriya!

Ochako: He did it! He saved him!

Rex: I knew he had it in him!

They keep cheering, but their victory is cut short as the scene then shifts to All Might and One for All, already having exchanged blows.

Izuku: This isn't over yet...

The air was tense as All Might and All For One faced each other, the ruins of the League's old hideout now smoldering around them. The echoes of distant explosions still reverberated through the streets. Citizens and heroes alike watched, breathless, as the two of them squared off, their battle about to decide the future of hero society.

All Might's muscular form stood tall, his smile replaced by a hardened expression of determination. His once bright eyes were clouded with fatigue, the embers of his strength flickering.

All For One: You've come a long way, Toshinori. But I'm afraid our game ends here.

Without warning, All Might launched himself forward, his fist cocked back, aiming for All For One's chest. His speed was still blinding, and the wind whipped behind his punch.

All Might: SMMMMMMMAAAAAAAAAAAAAASH!!!

All For One raised his hand, layered with multiple quirks, and met the punch with a crushing force. The shockwave shattered nearby buildings, sending debris flying in all directions. All Might grimaced as their fists collided, feeling the strain in his arm, but he pushed harder, trying to overpower his nemesis.

All For One: You still have fight left in you. How... entertaining.

All For One then twisted his wrist and summoning a blast of kinetic force, blasting All Might back and crashing into the ground, skidding through the broken concrete.

All Might quickly regained his footing, wiping blood from his mouth.

All Might: I'm not done yet!

The number 1 hero blasted forward again, his other fist glowing with raw power. He swung at All For One's head this time, but All For One dodged, his own counterpunch laced with air pressure quirks, slamming into All Might's ribs.

All Might: URGH!!!

All Might coughed up blood, but he swung back immediately with a right hook that connected with All For One's jaw, sending the villain staggering. All Might followed up with a flurry of punches, each one more forceful than the last, but All For One continued parrying with precision, each blow reverberating through their surroundings like thunderclaps.

All For One: You can't keep this up forever, old man.

All For One grinned behind his mask. He gathered several quirks at once—air cannon, springlike limbs, strength augmentation—and unleashed a powerful blast straight at All Might's chest. The force slammed into him like a freight train, knocking him back yet again. All Might dug his feet into the ground, grinding to a halt as the ground cracked beneath him. He was used all of the power he could muster to withstand the attack but he was still left smoking.

All Might: Tch! You're calling me old? That's rich coming from a fossil like you!

All Might's muscles bulged once more, but he was sweating, his breaths coming out ragged. He was exhausting himself in this fight and transforming back fast.

One for All: Yes, that's it! Show the world your pathetic skeleton form!

For the first time, the entire world sees All Might weakened and on the verge of defeat.

Gran Torino: Toshinori! You've reached your limit!

All Might ignores his mentor and charges at All For One again, the two of them trading rapid-fire blows, but as the fight goes on, All Might is growing weaker and weaker. His time is up. These are his last embers of One For All.

All Might: It doesn't matter. I've got to stop him. I will defeat you, no matter what!!!

All for One: I've heard that same line before, you know. From the person who held One For All before you! Nana Shimura!

All Might: My master was a true hero! Keep her name out of your filthy mouth!

All for One: And the way she died was so pathetic. Shall I tell you all about i-!

All Might: ENOUGH!!!

All Might attacks him again, but All For One blasts him away, sending him flying high into the air. Gran Torino manages to catch him, and the two of them tumble back toward the ground, still standing.

All Might: *panting* Even as my body rots and grows frail... even as you expose my weakened state... in my heart, I remain a symbol of peace!

All for One: Is that so? That's not what my apprentice told me. He said you were just another government hero who uses violence to solve all his problems. Oh, and did I forget to mention? My apprentice, Tomura Shigaraki, and Nana Shimura's grandson.

All Might: T-That's a lie!

All for One: Oh, come now. You know it's the truth!

All Might: *shaking* You... bastard!!!

As All Might stumbles, losing his composure for just a moment, All For One seizes the opportunity. His expression darkens as he channels one of his many quirks, a massive bolt of energy crackling to life between his hands.

All For One: Die, Symbol of Peace!

With a swift motion, the enormous blast of raw power hurtles toward All Might. Time seems to slow as Deku watches in horror, his heart sinking. His hero—his All Might—was about to die, and it would all be his fault for dragging him into this fight.

Without thinking, Deku sprints forward, eyes locked on the bolt of energy.

Deku: ALL MIG-!

Before he can finish, the explosion engulfs him, swallowing him in a cloud of smoke and debris.

All Might: YOUNG MIDORIYA!!!

Ochako: DEKU!!!

For a brief, heart-wrenching moment, there is nothing but silence. The battlefield stills, the air thick with dread. Everyone stares, fearing the worst.

All For One: Foolish child. So eager to die for a symbol that's lost its meaning.

He turns back toward All Might, his voice dripping with malice.

All For One: Now, where were we?

All Might's eyes widen in grief and fury, his fists trembling as he feels the weight of his student's sacrifice. But then—

"HEY! POWER HOARDER!"

Music Insert:

All eyes snap to the smoke, hearing the staticy voice.

All Might: M-Midoriya?!

Ochako: Deku?

All For One: What is this?

The dust clears, revealing a new figure standing tall in the center of the devastation. Deku, now transformed into Feedback, contains the energy blast in his plug hands, arcs of electricity crackling between his antennae.

Feedback: You're not laying a finger on All Might! You want someone to destroy? Try me!

The ground trembles under the strain as Feedback absorbs the energy into his body, surging with newfound power.

Iida: Is that really... Midoriya?

Ochako: It's gotta be! He turned into Feedback!

His friends watch, stunned by the sight. Above them, Feedback stands tall, his hands grasping the enormous energy bolt, now surging with green Omni-Energy combined with his own power of One For All.

Feedback: Heroes like All Might stop monsters like you! And if I can't stop you here and now, how can I ever hope to become the next Number 1?!

All For One: Ignorant child. This does not concern you. Leave now, and I may consider sparing your life.

Feedback: Sorry, Baldy. Not happening. I'm stopping you, right here, right now.

All For One's smile fades. His voice, low and menacing, drips with malice.

All For One: Very well, if you seek death so eagerly... What name shall I carve into your tombstone?

Music Insert:

Feedback's tendrils pulse as he finally grasps full control of the energy, a smirk spreading across his face.

Feedback: The name's Deku. And you may have heard these words before, but I'm going to show you what they really mean—

He charges the energy forward, the ground rumbling beneath his feet as the power intensifies.

Feedback: IT'S HERO TIME!

One for All charges at Feedback, ready to end the boy's life, as Feedback winds back his arms and fires an even bigger blast than the one he'd fired at the Conductoid previously. One for All goes crashing into a wall with very visible damage. Feedback can be seen still standing and ready to fight as Omni-energy, and One for All begins sparking all over his body. Without hesitation, he transformed into Fourarms and with a single leap, he closed the distance, bringing all four fists down at once on the villain, sending him reeling backwards.

All For One raised his hand, multiple quirks activating in a twisted dance of destruction. Shields of dark energy formed, absorbing the blows, but cracks quickly began to form. All For One. Impressive strength... but raw power alone—!

Before he could finish, XLR8 replaced Fourarms in a blur, his sleek, blue body moving so fast that the air itself howled. In the blink of an eye, Deku circled All For One, delivering dozens of rapid strikes, targeting every weak point he could find.

All for One: ARGH!!!

XLR8: What's wrong? Too slow?

XLR8 then spins around the villain, surrounding him in a vortex before ramming headfirst into him, creating a small explosion.

XLR8: KINET SMASH!!!

All for One is knocked off balance and attacks once more, sending projectiles flying toward the hero, but he transforms again, and as the dust clears, Diamondhead can be seen running toward the villain firing, projectiles as he jumps high into the air.

Diamondhead: PETROPIA SMASH!!!

The Petrosapien slams his fist onto the ground, causing giant crystals to shoot upwards, knocking the villain back. After getting close and landing several solid hits on All for One, he then transforms into Four Arms and sends him flying with a Sonic clap, followed by Heat Blast, who throws fireballs and creates a ring of flames around the villain.

All for One escapes and goes in for another attack, using his rivet stab to try and grab the hero, who transforms into Big Chill and freezes them, causing them to break. Big Chill tries to freeze All for One in order to slow him down, then turns into Cannonbolt and rolls into the villain, slamming him down and sending him into the dirt. Cannonbolt jumps up and transforms once more into Armodrillo to try and bury All For One, who manages to dodge and strike back, this time making his right arm stronger and more muscular, slamming it into the ground hard.

All For One: ENOUGH OF THESE GAMES!

All for One realizes, however, that this is not the end, as Goop arises from beneath his first before firing gunks of slimy acid at his face, followed by a strong punch to the gut by Chromastone, who pushes All For One back with a super powered multi-colored beam of energy, followed by Spidermonkey swinging around and blinding him down with webs.

Spidermonkey: Missed me! Swing and a miss! Strike three, you're out!

Spidermonkey then kicks All for One away. The villain goes sliding back, but before All for One has time to react, he turns into Water Hazard and pushes him back with two powerful torrents, followed by Ampfibian shocking the now wet All for One and using this as a distraction. Deku then turns into Fourarms again and spins him around a bit before sending him flying into a wall.

All For One: Ugh... such... power. It's even greater than I imagined! I want it!

Deku transforms back to human temporarily

Deku: Had enough?

One for All: Fool. You've only piqued my interest further. That quirk... the power to transform at will... IT SHALL BE MINE!

He fires his tendrils once more at Deku, who turns into Brainstorm to defend himself using an electrical barrier.

"BRAINSTORM!"

Brainstorm: Now I am most decidedly miffed!

He opens his shell and fires another bolt of lightning at the villain, followed by Echo Echo, who uses a Sonic blast to make One for All lose concentration. While he's distracted, he changes to XLR8 once more to strike him again, followed by Rath, who begins to go wild on him.

Rath: LET ME TELL YOU SOMETHING ALL FOR ONE, LEADER OF THE LEAGUE OF VILLAINS AND NUMBER ONE ENEMY OF ALL MIGHT! YOU THINK YOU'RE SOME BIG SHOT JUST 'CAUSE YOU STOLE A BUNCH OF QUIRKS? RATH DOESN'T CARE IF YOU'VE GOT A HUNDRED QUIRKS OR A THOUSAND QUIRKS! RATH'S GONNA KNOCK THAT STUPID MASK CLEAN OFF YOUR FACE!

Rath continuously pummels the villain left and right while ranting at him.

Rath: YOU'RE NOT EVEN HALF AS TOUGH AS YOU THINK YOU ARE! RATH'S GONNA PUMMEL YOU INTO NEXT WEEK, AND THEN WHEN YOU WAKE UP, RATH'S GONNA PUNCH YOU AGAIN FOR MAKING RATH GET UP SO EARLY!!! APPOPLEXIA SMASH!!!

Rath grabs the villain and throws him onto the ground, creating a massive crater. All For One is in complete shock at the beating he's receiving. Nobody's ever fought him like this, not even All Might.

All for One: W-Why you-! Y-You can't defeat me!

Rath turns into Humungousaur and grabs All for One by the leg slamming him around like a ragdoll before throwing him high into the air. He then turns into Jetray and flies up to him at high speed, causing a sonic boom, grabbing him and flipping him downloads, shooting neuroblasts from his eyes to make him fall faster. All for One hits the ground hard, making a massive crater. As he struggles to get up, he looks up as darkness hovers over his head.

Humungousaur: You just made a HUMONGOUS mistake! TERRADINO SMASH!!!

Before the villain can react, Humungousaur crashes down on top of him, creating a massive shockwave that blows everyone away. Everyone is in shock. As the dust clears, All for One lies unconscious on the ground. Deku is now in his human form.

There is a short silence, but then the crowd and pro heroes begin to cheer for the boy who had finally defeated One for All, one of the most deadly and dangerous villains on the planet. Deku looks around in awe of what he'd just accomplished. He defeated All Might's strongest enemy. He turns to All Might, partially deflated, who gives him a big grin and a thumbs up.

All Might: Heh... Nice work out there, kid.

All Might then begins to deflate into his skinny form, letting off steam. As he does, he points toward his pupil.

"Next, it's your turn..."

Deku looks at him and smiles, but the celebration is cut short when he hears groaning. All for One is trying to get back up. Deku walks over to him.

Deku: It's over. You lose, All for One. Do you yield?

All for One: Hehehehe... yield? Do you know who I am, boy? Hahahaha... I'm the Demon Lord of this realm! I am what makes heroes like you run and cower in fear.

Deku looks at the now defeated villain laughing, unimpressed by his threats.

All For One: *laughing and coughing* I won't... back down... not from the likes of you... this isn't over... you may have beaten me now...  but someday... I will return... and I will crush your feeble hope and the Symbol of Peace. Your power... will be mine... hahahahaHAHAHAHAHA!!!

Deku just gives him a smug look and scoffs at him as he's laughing.

Deku: Yeah. I thought you might say something like that.

Without even touching the Omnitrix, a green flash of light appears and now standing before All for One is a Celestial Sapien.

"ALIEN X!"

All for One is in shock and unable to get a single word out in the presence of the god-like alien.

Alien X: Seconded. Motion carried.

All For One: W-Wait! What are you-?!

He uses his power to lift up All for One and returns every single quirk he has ever stolen before removing his quirk of All for One entirely.

Alien X holds the physical manifestation of All for One in his hands before crushing and destroying it.

Alien X: To think you saw yourself as some kind of god... but you're just a feeble old man, hungry for power.

He then drops him before changing back.

All for One: What... did you do?

Deku: I returned what you stole. Every single quirk you've ever taken has been returned to its rightful owners. And I made sure that you'll never threaten anybody, ever again. You lose.

Music Insert:

All for One, now powerless, can only lie there, completely and utterly defeated. He has no power. He has no edge. He has nothing. All of these years plotting and scheming, every victory he's ever had over the heroes over the past wielders of One For All, none of it matter now. The Demon Lord feared by had been bested by Izuku Midoriya.

The crowd cheers for their hero, all of Deku's friends and his teachers calling out to him. Deku is a bit embarrassed about all of the attention but just smiles. Ochako then goes running to her best friend.

Ochako: DEKU!!!

Deku: Hey!

Uraraka then glomps onto her best friend.

Deku: Woah!

Ochako: You scared the crap outta me, you... you.. DOOFUS!!!

Deku: Hehe... sorry. It was kinda a heat of the moment thing.

Ochako: Don't ever do that again!

She hugs him as Iida, Rex, and Todoroki all join in.

Rex: DOGPILE!!!

They all celebrate their victory while Kirishima is on the side helping up a now cured but still injured Bakugou.

Bakugou: Ugh...

Kirishima: Easy, bro. Let's get you to a doctor.

Bakugou: The fuck happened?

Kirishima: It's alright now. Midoriya took care of everything.

Bakugou is too weak to get mad, but those words resonate in his head.

"Shitty Deku... how the hell did he get so strong... one day... I'll surpass him..."

All Might looks at his pupil with pride. At this moment, the remaining flickers of One For All within All Might finally dissipate. The moment has come.

"Goodbye... One For All..."

As they're all celebrating, however, Izuku doesn't realize that the Omnitrix Master Control has been zeroed out, and the watch faceplate is now flashing and crackling with orange lightning. After a few seconds of flashing, an orange ring appears around the Omnitrix dial.
