Summary
After Leo is saved from the Prison Dimension, his brothers quickly realize that more happened than they had realized. Leo would get random bouts of feral bewilderment and had random triggers that had not been there before. What had happened to him?
Gaichū doesn’t understand what happened. One moment he was in his home, running away from a beating from Master and the next… well… the next he found himself in a strange new world surrounded by new enemies who seem to know him. Now he has to learn to navigate the peculiarities of this new place and hope Master won’t find him.
Peculiarities such as gravity.
And light.

Summary
“What must Michael think of his big brother, reduced to being my nightly meal? Or dear Raphala, seeing his loud, cocky little brother silenced by the euphoria of being bitten and drained?”
Leo was panting in his lap, cunt tightening around his dick. “Dee, please…” He hid his face, shoulders climbing towards his ears as he shied away from the softshell’s words.
“Papa made you the leader because he knew you could take charge. He thought you could actually lead. Does he still believe that now? What must our dear old father think, having a needy whore for a son?”

Summary
Halloween was approaching and his twin, usually excited for the holiday, was still struggling with his mental health. The softshell wanted to do something for his new mate, he wanted to see a true smile on his slider’s face.
Spinning his chair idly, his gaze flicked around the room, mostly lost in thought but also looking for ideas. His eyes caught on the cozy nest set-up on the spare bed, where he and his twin would curl up to watch movies when they both struggled to sleep.
That’s it! Nostalgia movie night.

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
Since the invasion, Leo would sink into his darker thoughts when everything became too much and he felt like a failure.
Donnie, however, wouldn’t allow his mate to reach that point. If his brain didn’t want to stop running, Donnie would make his twin’s brain shut down.
He exhaled quietly, focusing on how his dick felt in that warm, wet hole.

tell me, who's watching? by Bean (elyrey)

Summary
Leo fussed with the nest he’d made on his bed, adjusting the pillows and blankets — and the spare masks belonging to his oldest and youngest brothers. Having the scents of his family always made laying eggs just a bit easier, feeling protected when he was so vulnerable.
He’d never been insecure about his nests, he’d throw one together based off his instincts, and he was happy with the result. This year was different though. This was his first egg laying since he and Donnie got together, and Donnie would be watching.

Summary
His chair spun around, a soft chuckle leaving him as he saw his twin.
Leo had created a makeshift nest on the spare bed he kept in the lab, pillows piled high behind him to help prop him up, and that’s where his mate was dozing.
One of Leo’s hands was curled around Donnie’s favorite hoodie, holding it close to his head, and the other… Donnie’s hands flapped in a happy stim as he saw Leo’s other hand resting protectively over his very round plastron.

Summary
He sat back down on his bed, pulling the box into his lap and— stopped. His instincts were warring inside him. He had most of a lifetime of great gifts from his twin that said whatever was in the box would be amazing.
But his neck also felt hot and itchy.
Leo threw the lid open before he could work himself into a panic.
Leo stared into the box, wide-eyed at the contents. Inside sat two replicas of Donnie’s cock, one plug, and a sheet of paper. All three toys were in Donnie’s signature shade of purple.

Summary
Mikey opens a portal, drags Leo through, and scatters into mystic dust.
He then finds himself in his future self’s mind-palace and given power laced with someone else’s memories. Mikey wakes in a New York that resembles his own, populated by alternate versions of his family who smile, fight, and joke like the brothers he remembers.
But the memories in his head whisper a different story: Krang-tainted faces, altered motives, and a future that took everything from him. Haunted by visions that may not be real and armed with a power he doesn’t fully understand, Mikey must choose whether to trust the people before him or the trauma inside his head.
The wrong choice could cost him the only home he’s ever known.
Or,
This is what happens when Raph and Donnie don't help Mikey with the mystic energy load when he opened a portal.
A ROTTMNT x TMNT 2012 crossover full of grief, cosmic consequences, and the endless lengths one little brother will go for family.

Summary
Since they were little, Leonardo has been the one to be there for his brother in what emotional confort implies.
Raphael was the one that takes care of them and is there for them like a parental figure, Michelangelo is the therapist and Donatello the genious that comes up with gadgets and has a lot of knowledge.
Leonardo was the face-man, the analyst and the comical relief, the doctor of the family and the one who knows how to deal with his brothers when they aren't feeling well and didn't want a lot of feelings involved in the interactions but also didn't want to be alone. Neither of the other three knows that Leonardo is the same towards the three of them, and Leonardo doesn't mind if they know or not, it's their choice to tell the others how they feel. But Leo doesn't tell them when something is wrong with him, in his words that would just "make them feel worse, make it like their problems doesn't matter and add more work to him" so he just stays silent, because, if he isn't the doctor and the emotional support of his brothers, what is he?
OR
Leo knows everyones problems and helps them but when it comes to him, he is all alone by his own choice.

Summary
“Normal humans can’t come back from assimilation,” says Casey, tone flat, his eyes fixed on the news footage, as they all sit in Leo’s room and watch soldiers mow down a small swarm of pink-fleshed zombies. “Mutants and yokai can, sometimes,” Casey glances at Raph, who doesn’t look away from the TV, “but it usually takes a lot of mystic energy to fully clear the infection out.”
“Energy that humans don’t tend to have,” Donnie guesses, and Jones hesitates before nodding.
“We should be out there,” Raph mutters, claws digging into his knees, until Splinter clicks his tongue, gently chiding, and pulls one of Raph’s hands into his own.
“The military seems to be handling it fine now,” Donnie says, to the echo of gunfire on the screen. “I say we let them. We’re not in any shape to be fighting, anyway.”
Mikey’s soft snoring, and the steady beep of Leo’s heart monitor, both punctuate that statement for him.(Or: The Kraang were defeated. The world was saved. The Hamatos are safe to rest, and recover, and rebuild. ...So why does it still feel like the other shoe's about to drop at any moment?)

Summary
“Hey, no, look at me,” Donnie snapped — vocally and literally, fingers inches from Leo’s face. “I need you to answer me something, but it’s a simple yes or no. Can I hold you?”
Leo nodded, ashamed. He felt Donnie’s arms wrap around him and haul him into his lap. He tucked his head into his twin’s neck.
“I know you, sometimes better than I know myself,” Donnie said, voice low as he rocked them slightly. “You only break down like this when you start spiraling. Whatever it was, it’s wrong.”
“Can’t do anything right,” Leo whispered, hoarse from crying his heart out. “Fucked up macaroni, just like everything else. You’ll realize it soon, when you’re not scared of losing me anymore. You’ll remember that I’m incompetent, and this just proves it.”

A Not So Good Day by Leonardo1885

Summary
The hinges had groaned, and the door caught for a moment before it began to move more easily.
But that’s where Leo’s luck had given out. The edge of the door had begun to swing forward faster than Leo had been prepared for. It had knocked into his bad leg, which had whited out his vision at the same time he’d felt himself falling forward. Automatically, he’d thrown his hand out to catch himself on the wall, but only found open space, he’d dropped his crutches automatically trying to find something, anything to grab onto to stop himself from falling, and had found the edge of the doorframe. He’d had just a moment to realize he was on the wrong side of the closet door when something heavy had knocked into his shell.
With his balance already precarious, and his fingers wet with sweat from all the walking he’d been doing, his tedious grip was wrenched free from the doorframe as he was shoved deeper into the closet before the door had shut, enclosing him in darkness.
----------
Or Leo finds himself trapped with no way of contacting his brothers. But it's all good because he's technically still in the lair, right?
