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
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
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
Without needing to be prompted, Donnie and Mikey jumped through, the latter being supported by the former as he limped along - he’d be due for a medical check once they were all accounted for. Raph followed, expecting Leo to cross over and cut the portal off once they were all clear.
What the two of them didn’t account for, however, was the shrill noise that echoed throughout the ruined station, setting all four Mad Dogs on edge.
Or: Why doesn’t Leo use his portals in the future?

Summary

Summary
Sometimes, being unseen hurts more than any wound. Donatello just wanted to be understood to be noticed for more than what he could build or fix. But when no one seemed to listen, that emptiness started to whisper louder than reason. The Shredder saw what his family didn’t: potential, brilliance, and a boy desperate to belong. And in that search for belonging… Donnie made a choice that would cost him everything.
Raised in the Foot Clan’s shadow, Donatello becomes an invaluable asset to Shredder. Manipulated with lies and twisted truths, he grows up believing that Splinter was the evil one and that his brothers were never truly his family. Shredder has not only taken one of Splinter's sons but has turned him into his own heir—a weapon capable of destroying the very family that raised him.
When the time comes, the turtles finally emerge from the shadows and confront their lost brother, only to discover a cold, hardened Donatello who no longer remembers them the way they remember him.

Summary
“How old is he?”
Leonardo pauses his stirring. He half-expected a joke—an innocent little jab meant to lessen the tension thickly clouding the kitchen—yet Leo’s voice is quiet, serious.
So Leonardo turns around and offers the same air of calmness that the teen approached him with. Yet his chest constricts when he has to angle his head down low to meet Leo’s eyes, and an overwhelming sadness withers his heart as he takes in that young, bright-eyed face. Leo is a child, a baby.
And he’s going to cause the end of the world.
Or, Casey Jones goes through the time portal, but he’s a baby in Leonardo’s arms. And one traumatized turtle juggles being a new dad while trying to prevent a horrible future.

A cunning and powerful mystic, Shen seeks to steal the Hamato Clan’s ninpo, intending to ascend beyond mortality and reshape the world in her image.
