ROTMNT OC AU - The Rise of Sophie by mostlyroughdrafts

Summary
Sofonisba "Sophie" Hamato - a mutant female painted turtle with pink accents on her hands, legs, eyes, and a heart-shaped birthmark on her clavicle. She is also missing a finger on her left hand. Follow her on her many adventures as she tries to find the warrior spirit she lost.
-
Author's Note: Basically this is an AU where the brothers would have a little sister and what she'd do with and without her brothers. There will be some chapters that are like lore and some that are like filler. I'm trying to emulate the show's style of writing. She's an OC and this is just a fun writing experiment for my current hyper-fixation so I hope you enjoy :)
(Also I'm following Paramount + episode order since both seasons are on there and that's where I started watching the show) -

You won't let me fight? Guess I'm sneaking out, then. by LucaWrites

Summary
A strike was aimed for his face; he managed to dodge. The brass knuckles skimmed his cheek, but nothing worse. His ribs throbbed, but he still spun his nunchaku and when his opponent lunged in for another hit, caught their arm in the chain and slammed them into the arena floor.
The crowd groaned in sympathy, but the dragonfly was up and darting around the arena before they finished.
He could feel the ratcheting increase of alertness as the adrenaline began flowing through his body. He hit the switch in one of his nunchaku handles and the blade popped out, and he hit the switch on the other end that held the chain extensions. The chains pooled onto the arena floor as his opponent sped around the arena at dizzying speeds.

Summary
It started with nail polish.
Well, not really - it’s always been there. An ever-present sense of isolation, of wrongness that pulled at his skin and made his heartbeat stutter.
But he likes to say it started with the nail polish, so it started with the nail polish.

Summary
Mikey had spent his entire childhood believing he only had one older brother. After an unlikely encounter turns his world upside down, he soon discovers a world—and a family, by extension—that's been hidden underneath his feet the whole time, and he's determined to reach out and make sense of it all.
As it turns out, Donnie is just as desperate to connect with his lost family on the other side of things; all in spite of both his and Mikey's respective older brothers not wanting them to.
(They really, really don't want them to.)

Summary
"Donnie braced a hand against the slick tile, his chest tightening as his breath stuttered. His circuits hummed, buzzing under his skin as though his own tech was betraying him. He shut his eyes, but that only made it worse.
Leo, broken.
Leo, gone.
Leo, almost never coming back.
His hand trembled as he reached out blindly, desperate for something—anything—to ground himself. His fingers closed around a bottle. Not his usual shampoo. Not the generic citrus scent he always used. No, this one was his twin’s"-or-
The smell of Leo's soap brings comfort to Donnie, but having his actual twin comfort him might be even better

Summary
“Hmm.” His Master mused. “Now that it’s woken up, it won’t be able to return into its cryogenic chamber. It’s useless to me in that weakened state. I suppose I will have to make a new one.” He stated. “Specimen, dispose of it.”
He visibly twitched. His heart started pounding in his ears. The shouts from the others faded from his mind as all he could hear now was ringing. The small one’s head tilted up, her big eyes staring right into his own.
He had to move. He had to obey. But he-
“Specimen.” His Master said.
And suddenly the noises were back. Too loud. He forced a step towards her. Then another. His body was stiff, his fist closed so tight his knuckles were turning white.
He kneeled in front of her. Her head moved to watch him. He placed his hands around her shoulders. He was shaking. Why was he shaking? This was just a mission. Why couldn’t he do this?
He pressed her shoulder harder, squeezing her lungs together. She was so small. So very small.
“Don’t ya fucking dare, ya monster!” The red one yelled.
She yelped.

Bishop figured that creating mutant turtles was his best bet at defeating mutant turtles. It didn't go quite as expected. For anyone.

In the midst of a relatively quiet night in New York, Spider-Man and the Black Cat are ripped from their reality by a blinding white light. They are thrown into the Crucible, a vast arena dimension made of ruined cities and impossible landscapes, under the silent gaze of a purple, ringed planet.

As the mysterious "Entity" watches and its relentless Hunter begins to test the "specimens," unlikely alliances are forged in a desperate fight for survival. Spider-Man must navigate this dangerous new ecosystem, where every encounter could mean salvation or annihilation.

Summary
It’s safe to say that the others had many concerns when they got Mikey out of Dimension X. They asked reasonable questions such as: how long were you in there? What happened? Are you hurt?
Mikey didn’t mind it, of course they’d have questions, but there was a problem.
He didn’t have any answers.
