Summary
Months after the Krang invasion, Donatello begins to experience severe shell irritation. When tests reveal leftover Krang matter lodged deep in his shell from the Technodrome explosion, Leo and Draxum perform a delicate extraction procedure to save him. Recovery seems promising—until Donnie collapses weeks later and begins coughing up blood.
After an emergency evaluation, Draxum delivers the devastating diagnosis: a rare, aggressive form of cancer, likely triggered by the Krang residue. As Donnie undergoes harsh treatment, Leo—driven by guilt, love, and fear—digs into his medical training, determined to find a cure. He refuses to let his twin slip away, even as Donnie weakens by the day.

Summary
It's been years, decades, since the Kraang split the sky and rained down death and destruction, but they still live on. They still fight.
But no matter what they do, no matter what- who they sacrifice, the Kraang always seem to come back stronger.
It may be time to try something different, a last resort. Something that won’t save their world as it is, but stop this carnage before it could even begin. At the very least, Casey will be safe, right?
tldr: Casey Junior’s original timeline, and what led up to Master Leonardo tossing him through time and space with only a faded photo and a frantic plan. And then, the aftermath of that choice.

On that fateful night, Lou Jitsu escaped with four turtles. But he had hoped to escape with five. A fifth turtle that had bit through its cage and fell into unrefined ooze, accidentally mutating early. During the lab explosion, both Draxum and Lou Jitsu believed the fifth turtle to be dead. But unknown to them, it was saved by a human war veteran, one of the few humans to ever walk in the hidden city. He found the little turtle and took it home, and named them Cellini.
But he left them. Somewhere even the living can't reach.
The Hamato brothers never expected to take in someone.

Too bad family doesn’t stop the nightmares.Or the man who lost an eye.
After all, the past has a way of following.
———Or, the turtles discover they have another sibling, Cellini (they/them) and bring them into their family, now stuck in this chaotic fun!

Summary
Merging with a Technodrome has life altering consequences... or more specifically life ending ones. While dying is uncomfortable, awkward, (and a bit of a chore,) the idea of his family continuing on without his technical skills is unbearable. Literally the pineapple on his pizza. The concept is so grating that Donnie will do anything to make sure his family is taken care of once he's gone: Even if it means transplanting another version of himself from another timeline to take up the job opening.
In Casey's Timeline his Donatello died in an extremely convenient-to-obscure way. A body was never found and his death was never explicitly witnessed. The only reason they know Master Donatello "died" is because his circumstances were "inescapable" but Donnie is sure he can put up some air quotes. Removing this other Donatello from Casey's Timeline wouldn't change the future that has already happened or create a new timeline. So what's the harm in taking someone from a timeline that doesn't need them anymore?
Or: Donnie needs to replace himself before he dies at the young age of seventeen and Master Donatello becomes the candidate for that endeavor... by force.

Summary
Two different worlds. Two different teams of siblings. One enemy that refuses to stay buried.
When Raph vanishes through a crackling portal, her family discovers a nightmare they thought was over: the alien conquerors are back, their grotesque machines spilling across dimensions. A rescue mission becomes a race against time as the turtles search rooftops, shadowed alleys, and hidden realms where mystic power is stripped away — while Raph fights to keep herself from falling into the uncontrollable fury of her Savage state.
But this battle isn’t theirs alone. Another team of turtles, older, battle-worn, and scarred from their own war with the invaders, is pulled into the chaos. Two generations. Two dimensions. And one impossible choice: trust each other, or watch both their worlds consumed.
The portals are opening. The Kraang are waiting. And family may be the only weapon strong enough to survive.

Summary
Donnie stared at his brother in horror. It was bad enough seeing his family torn apart like this, but he’d thought he knew what he was getting into.
He was wrong. Utterly, despicably, irrevocably wrong.This wasn’t the future Casey had come from.
This… this was something else entirely.
——————
Or: Donnie gets into some shenanigans, 2003 style. Because banishment from Witch Town wasn’t good enough- one of the village’s residents wanted him to feel the pain he caused.(Inspired by tavrosnitram12 on Tumblr)

Summary
Orange screeches in shock, stumbling back.
“Hey, they were working for Big Mama!”
“Oh shoot they followed us-!”
“I’VE GOT THE TRANQUILIZER-”
“WAIT!!!” I throw my arms up in a surrendering motion. “WaitwaitwaitIdon’twant tofightyou!”
Leo leaps onto Purple’s back, wrestling the tranquilizer out of his hands, “Okay we’re getting a little too trigger happy-”
“You never let me shine-!”
“Whaddya want? We ain’t giving you the goo! And we sure ain’t going back to Big Mama!” Raph growls.
“Yeah!” Orange agrees vehemently.
“Okay, okay, I’m not here for that, just- just hear me out,” I say carefully. All four squint at me suspiciously. Still holding my other hand up, I slowly reach for my mask with the other, then I remove it.

Summary
“Ah, yes, I’m sure you have many questions for me, including how I know about your fascinating mystic abilities. But your questions are inconsequential, I know all about you and your family. I’m also aware that you turtles are the ones who were responsible for stopping the alien invasion a couple years back, along that giant portal in the sky last year. You and your so called brothers have been quite a matter of interest to me for some time now. It hasn't been easy finding you, but I knew it would only be a matter of time until we did. Of course we had to take precautions regarding your particular abilities. You won't be going anywhere so you might as well get comfortable. Welcome to your new home, turtle."
Leo groaned, ignoring the aches and pains in his muscles as the man turned to go, desperation pushing the words from his sore throat. “Wh… who are you?”
The man paused, glancing at Leo from the corner of his eye, lips pursing in consideration for a moment before he turned to face him again. His smirk returned as he fiddled with the dark glasses on his nose. “I go by many names, but if you must address me, you may call me Bishop.”

Summary
The Techno drone wasn’t meant to be ever separated from its pilot. Yet Donnie forcibly got ripped out of it. But that never meant that the Techno Drone also got ripped out of Donnie. Or that the softshell’s parts all come back with him. What will a turtle do if he finds out that he’s partially Krang and that part is actually the majority of him?
Or the Techno Drone didn’t just Krangified, but straight up made Donnie 70% Krang. Of course with a species change comes some freaky new instinct, issues and body horror worthy transformations. Drowning in intense self hatred and fear of losing his brothers ( especially his twin) of course he tries to face all these challenges all alone.
Basically another Krang-Donnie AU, but trust me this is going to be a rollercoaster of very gory, very sweet and have a lot of made up Krang lore you never knew you needed.

Summary
Because Mikey’s not paying attention to what’s in front of them, Leo sees it first through the thinning fog. He thinks it’s a tree trunk at a glance, tall and slender and curving oddly where it rises above the others. Then it moves, bending as if in a wind, and by the time it twists around to face the car, Leo realizes it’s not a tree at all.
“What,” he says, feeling entirely too small in the open-top Jeep.
Mikey, who went through a dinosaur phase that lasted the entirety of his pre-teen years, points at it and declares, “Sauropod!”
“Animatronic,” Leo says, “right?”
“Right,” Mikey parrots automatically. Then, more slowly, “I mean, it has to be. Right?”
“Right,” Leo agrees, but his heart isn’t in it.
The first Jeep has slowed to an abrupt stop, and theirs slows to a stop behind it. The dinosaur trumpets at them, like the elephants at Mikey’s zoo, and half a dozen other slender necks rise out of the mist at the call to peer in their direction.
