Months after the Krang invasion, Donatello begins to experience severe shell irritation.

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.

He refuses to let his twin slip away, even as Donnie weakens by the day.

Absolution by AlpineFresh

Summary
Leo didn't know what he expected Tommy's previous world to look like. Whatever he'd expected, it wasn't this. The ghost towns, the craters, the downright impossible water physics.
Well, all the better Leo hadn't included his brothers in this plan– Donnie would have spent so long trying to pick apart and quantify every little oddity they'd have never gotten anything done.
Either way, whatever came next; if this ended with killing Dream or not, Leo was ready for it.
AKA, Leo and Tommy's horrible DSMP bonding trip to finally kill Dream once and for all.

IMDb: When the Turtles discover Bigfoot in the woods, Donnie befriends it and insists they protect it from a hunter.

(This IS a non-con story and there IS sexual themes, but sexual intercourse never takes place. This is an exploration of the scenario that the episode sets up (and then ignores) on the topic of grooming. The SA depicted is not glorified or appraised in any form. This fic is better categorized as horror. If you're looking for romance, you're in the wrong fanfic.)

I Won a Part of You by CursedCatChild
Fandoms: Rise of the Teenage Mutant Ninja Turtles (Cartoon 2018)
24 Nov 2025
Tags
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.

"I get the feeling you're not really listening," Leo tsked irritably, looking over Mikey's shoulder. He tried to look him in the eyes, but Mikey turned his face away, avoiding him. Annoyed, the swordsman tapped his finger on Michelangelo's shoulder. "But you don't have to. After all, I don't mind repeating things to you. It's not your fault you're a little slow."
See? Leo was just trying to be nice.

The Brothers Hamato by clairakitty

Summary
The smart lock on his front door trilled, and Raph’s rant instantly cut off, the room falling deadly silent. Leo locked eyes with his brother, and it was clear that Raph hadn’t been expecting anyone else; a quick glance at Takeshi confirmed the same. Like a well-oiled machine, they prepared for an attack—Raph slipped on his brass knuckles, Tiger Claw drew his gun from its holster, and Leo deeply regretted not getting one of his guns from the bedroom when he had a chance. Leo watched, unbreathing, unblinking, as the front door swung open.
Not an enemy.
Hamato Saki. Head of the Hamato family, a subsidiary of the Tatsuo clan. Second in command of the Tatsuo clan, just under the kumichō. Both Leo’s blood father and his oath father.
In a world where the Hamato clan is a yakuza family and the turtles are human, Saki succeeds in killing Hamato Yoshi. Hamato Shen leaves for New York with Donnie and Mikey—leaving Leo and Raph behind. Over 15 years they became the Hamato family's most deadly members, until an assassination attempt sends them out of the country to protect a barely-remembered mother and brothers.
