Summary
Lucifer and Charlie find out that Alastor is still hurt, his injury from the extermination never healing. They try to pin him down to get healed, but a hurt Radio Demon is acting on pure instinct and is high with fever. In the melee, Alastor bites Lucifer. Right on his Angelic Mating Gland, something he'd never even allowed Lilith to do. After healing the recalcitrant, daughter-stealing prick, Lucifer is forced by his own biology to undergo a change. To become the best physical mate for the Radio Demon. That doesn't mean Lucifer is just going to accept it. NOPE! It doesn't matter how cute and shy the devious deer man was being. Those fluffy ears and cute little tail should be classified as Weapons of Mass Destruction. He would not give in!... … … Well... Shit.

Summary
Donnie straightened, reading the words a second time. A third time. He rubbed at his eyes to make sure he read it correctly. There was no way. The serum was making complete sense in his brain and it was only exciting him further.
“No way,” Donnie breathed. Pieces of the puzzle were beginning to click in his brain. “Oh, no fucking way.”
“I think I know you well enough to say you’re scaring me,” Casey said.
“I’m a genius,” Donnie said. “I mean, I know that. It’s undeniable at this point, but I am feeling so affirmed right now, because I just. I did that, Casey. I just…”
Casey blinked at him. “Please clarify?”
Donnie didn’t. He let the silence stretch so the pieces could fall into place, beginning to shake with excitement. He could go where no man had gone before, fix Casey’s problems like he desperately wanted to, and most importantly, break the laws of nature.
“Donnie?” Casey’s voice was small, because he’d spent enough time around a Donatello to know that face.
He had an idea.

Summary
The turtles are still reeling from their father's death when Donatello is kidnapped by Agent Bishop and implanted with three genetically-engineered embryos. For Don, escaping from Area 51 and preventing a second Triceraton invasion will be far easier than enduring a forced pregnancy, and dealing with the fallout within his rapidly evolving family.

I Won a Part of You by CursedCatChild
Fandoms: Rise of the Teenage Mutant Ninja Turtles (Cartoon 2018)
24 Jan 2026

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
What if instead of Leo, Donatello was the very last mutant alive? What if he was thrown fourteen years into the past to fix Leonardo's mistake? To stop the seemingly inevitable apocalypse?
Even worse, what if they only had three days to find the Key that unleashes the Krang? The same key that Dee had been trying to find for fourteen years, even trying to find its previous location before the invasion of the Krang and their ship proved futile.
What if, through these attempts at saving the world, he realizes that his world isn't a planet, it isn't the Earth. It's a person. The person who he could've been, the one he needs to protect. So that Donnie can have the opportunity to be the things that Dee feels it's too late for himself to be.
(Future Donatello is referred to as 'Dee' and present/past Donatello is referred to as 'Donnie')

The brothers wake up in a strange place they've never been in before, with collars around their necks, no memory of how they got there, and no means of escape. They soon learn that they're there to be studied and experimented on, but how bad will these tests be? They can't be that bad, right? Right...?
More tags will be added as the story progresses. The turtles are slightly aged up in this, with Mikey being 20, Donnie and Leo being 21, and Raph being 22.

Donnie was a genius, yet so goddamn incredibly stupid. Who would've thought injecting a serum that was on Alpha Stage was a bad idea? Well, he didn't. Now what is he going to do with this body suddenly being around 5 years younger?
Oh, his brothers CANNOT find out about this...No TCEST

Summary
For eight agonizing months, Shadow has been held captive by Black Doom, subjected to cruel experiments that have left him shattered in ways no one could imagine. When his friends finally find him, the Shadow they knew is barely recognizable—broken, haunted, and struggling to find his footing.
Determined to help him heal, they band together, offering the love and patience he’s always deserved but never believed he could have. Slowly, they remind him that he’s more than the sum of his scars—that he’s family, not just an experiment.
Through it all, Sonic is by his side, a steady presence and an unshakable anchor in the storm. No matter how far Shadow falls, Sonic is there to catch him, proving that even in the darkest moments, hope and connection can light the way forward.

Summary
The Ark was a relic from the past. The events that happened aboard the space colony tended to disagree with that statement, refusing to be forgotten from his hardened mind. He’s been hiding it all for years, keeping it all bottled up next to his bruised and broken heart. Trying to be normal despite himself, and failing miserably in the process.
Things are changing. Suddenly thrust into confronting his memories head on, Shadow must learn to live above his past and eventually, live for the future.
The Ark was a relic from the past.
Shadow refused to be one, too.

Summary
Shadow finally turned to him with a questioning eyebrow, defensive. “What?” They were allies now, sure, but their friendship was still tentative at best.
“Shadow, are you… Shorter than me?” Sonic asked.
Shadow blinked, unprepared for the question, and then blinked again.“What.” He repeated.
Wherein Shadow the Hedghog is getting left behind in every facet but the ones that actually matter, and he can't let that slide.

Summary
In Sonic's little world of Green Hills, Montana he’d come to understand humans as basically good. Some of them were Eggman, but most of them were Toms and Maddies and Crazy Carls.
And now there was GUN. Who’d committed an atrocity against Shadow beyond what Sonic thought possible. Instead of making amends for their past, they wanted its sole witness silenced.
“The doctors let me sleep in a real bed, eat real food instead of getting nutrient injections, watch movies and go outside to look at the stars. Because Maria fought for me to have good things.”
or
Sonic finds Shadow in the ruined lab before Gerald does.

Summary
Years after the events of the movies, Sonic moves out of the Wachowski's house to be an adult. Unfortunately, humans aren't accommodating to aliens, so with a machine Tails made, Sonic lives in Mobius in a house he built and frequently returns to Earth to be with his family.
A few weeks ago, Shadow came to stay with Sonic. The ebony hedgehog wanted to figure out what he was doing with his life, getting a taste of living alone (or somewhat alone) and Mobius.
Their proximity, however, gives their instincts an opportunity, and now they're rapidly hurtling into a new stage of both of their lives.
-
Way after all the movies, two adult hedgehogs (Tails is still a minor, tho)
Trigger Warning: Implied sexual content, mildly dubious consent, (Idk how to phrase it, but Sonic at one point thinks he assaulted Shadow but Shadow tells him that isn't the case, so there's no actual assault but there's discussion of it?)I'm writing a series about the characters instincts. Might as well do mating and pregnancy at some point lmao
It's also a request from Dark_Moon_the_Demon77. They don't accept gifts, so I'll just say it hereSeries

Summary
Sick of Sonic constantly inspiring the world, Eggman injects him with a serum intended to make the hero less... charismatic. Instead, it disrupts the delicate balance of Chaos Energy within Sonic's heart. Unable to hide his darkest emotions, Sonic grows violent and demanding.
Shadow believes he can cure him, but the Ultimate Lifeform's presence causes twisted changes in Sonic's persona, frightening their friends... and Shadow himself. However, Shadow also has parts of himself that he keeps hidden, parts that the corrupted hero would want nothing more than to expose.
