The Enemy's Heir by Truebluewarrior

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
A turtle. All angles and elbows, neon cutting sharp against the void. Two streams of blood marked his face, hidden under a blue mask. Leo?
Mikey slammed into him, wincing as he took in the bruises, the odd angles. The turtle blinked, eyes almost swollen shut.
“M'key?” He mumbled, before he tensed all up and grabbed Mikey by the shoulders, “Mikey! Nonono- you can't-” Mikey couldn't help but reach back, cupping Leo's face in his hands. They weren't blood, they were stripes. A Leo, turtle, blue mask, but.. not his Leo. Leo's eyes, fuzzy with pain, scanned over him fully.
“..you're.. you're not…” He breathed. Mikey shook his head, mask tails swinging and miserable. He wasn't. “You can't be here!” Mikey's mouth trembled,
“I dunno..”, he gasped, “I dunno.”
OR
Dimension X and the prison dimension give a similar vibe, no?

Summary
As much as Donnie would like to be a robot and simply keep working and advancing, they were cursed with a human body. A human body with emotional and physical needs. Suddenly, their mode dropped, along with their productivity, and Donnie came to the horrifying conclusion that they were lonely. They missed Mikey’s home cooked meals, now sometimes going far too long without eating. They missed Raph’s enthusiasm and spending time with him. They were even loath to admit they missed Leo’s dumb jokes. And staying up late with Leo when neither could sleep. And ranting to Leo about their day. And listening to Leo’s absurd Jupiter Jim theories. And Leo nagging them about wearing their back brace.
God, Donnie missed their twin.
(Or: Donnie suddenly starts struggling emotionally and physically while in college, but it's a good thing Tim likes to insert himself in other people's business! If only he could help with the random seizures and memory gaps Donnie has been having. A story about college, family, surgery recovery, gay idiots, and Donnie being bad at self care.)

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
Leonardo had always been a charmer.
He loved his siblings till the ends of the earth and would kill himself for their happiness but he had a mental illness that made everything he touched turn on him.
He had narcissistic personality disorder.
And he loved them of course he did! But they didn’t know that and he never made the effort to make them love him. He couldn’t even love himself. He couldn’t love anything.
He was unlovable.
They weren’t happy when he went into a coma For almost two years but they weren’t upset either since the hitting, yelling, and pain stoped when he was gone.
If he had died they wouldn’t have been too upset about it.
They must have hated him.
They must have despise him.
Since they gave away his mask, his Katanas, his title.
To a random human.
So if nobody liked him then way not push his limits and make their lives a living hell. While also going insane in the process.
Orrr
What if Leonardo went into a comma the day the left the sewer and woke up a year and a half later.
And Aprils the leader now!
New song for every chapter!! So recommend me a song!
