Summary
The rabbit seemed to snap back into focus, eyes back onto Leo’s. “Sorry, I'm bad with long speeches. Could you summarize for me?”
Leo squeezed his snout between his fingers, exasperated. “I need to see you again in a couple days.”
“Like a date?”
“Yes, like a–” Leo looked up frantically, blush spreading across his cheeks. “No, not like that! I'm worried about the severity of your injury!” He looked away again. “Look, is there somewhere we can meet so I can make sure you won't die from this?!”
“Wait what's your name?”
AKA Leo goes undercover as a battle nexus medic to try to uncover one of Big Mama's plots, but ends up treating a cute rabbit yokai instead

Weightless on the Rooftop (Will I Fly?) by lil_lavender3

Summary
He didn’t feel…anything.
Not the persistent dread, not the crushing weight of his own failures and guilt. Not even the constant fatigue from having to wake up every morning.
Maybe he would have felt happy, if he could.
Or,
Leo get’s cursed and is…happy about it? Will he try to undo it, or will it be the death of him?-

Summary
Mikey will never forget those horrible minutes after the portal closed, after Leo’s comms went dead, when he had wondered if he would ever hear his brother’s voice again. When he wondered what, exactly, his last words to Leo had been—they almost certainly weren’t I love you or please don’t leave so they didn’t count.
To make up for it, he wanted to tell Leo everything every chance he got. He wanted to make him laugh all the time. He wanted to crowd into the little twin-size infirmary bed to watch movies or do art projects that got glitter everywhere. He wanted to sneak out for smoothies even though it would get them in big trouble, because that was literally why he helped save the world in the first place.

Nothing by Shattered_ontheInside

Summary
"You're pushing me away just like you always did!" Raph accused, earning him a scoff in contempt. But he went on anyway. "Why!? Why is it so hard for you to admit you're hurting too!? What are you so afraid of!?"
Leo opened his mouth as if to answer. But changing his mind he turned around to continue walking down the street. Raph followed, matching his slowed pace while Leo didn't have the energy to deal with another yelling match right now so listened instead.
"I want things to go back to the way they were before with us."
No response, Leo kept on walking.
"Or if they can't go back that way there's nothing saying we can't work on this, together."
For reasons he didn't quite understand Leo walked straight past his apartment building, continuing on down the wet New York street.
"I don't want to leave things they way they are between us. It's been too long, don't you think?"

Summary
Shredder would destroy the Hamato clan from within. An infection would eat away at them little by little, until nothing remained. His intention was clear: he aimed at the captain of the ship.
But the responsibility for pulling the trigger wouldn't be his.

Summary
Looking back, Raph can count all the red flags he missed and hates himself a little more for each one. Leo sometimes causes problems for fun, and he likes to see what trouble he can get away with or get himself out of, and he is a downright menace to society when he’s bored—but he’s good. He’s sweet, and charming, and wants to help.
Leo wouldn’t have raised an issue with the other group of mutants, potentially cutting ties with useful allies, unless he had a decent reason to.

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
He did really want to go experience Día de los Muertos, but he wanted Donnie to come too. Partially because he worked really hard to help Señor Hueso set up and he wanted his mate to see his efforts, but also because from what he knew, it was a really cool concept.
Leo had spent a lot of time after the invasion thinking about death. But it wasn’t his own death he’d been so preoccupied with.
You want to know what really happens to your brothers in the future? They die. Everybody dies fighting the Krang.

never see a doctor by stillateenageabomination
Fandom: Teenage Mutant Ninja Turtles (TV 2012), Teenage Mutant Ninja Turtles - All Media Types
04 May 2025
Summary
Stockman said that they were rewiring Leonardo’s brain so that Saki’s presence emanated in every fired neuron and connected synapse. Saki likened it to taking a sledgehammer to his skull.
or, at the end of season 2, the Shredder decides to keep Leo and instead sends a message by hurling Splinter's comatose body through the window. This gives him about three months to break Leo down into something new, through a combination of sensory deprivation, sensory overload, and a whole lot of mindfuckery. He wants a loyal devotee, even if he has to cram love down Leo's throat until it's all he's capable of bearing.
or, a three part series examining the before, during, and after of the conditioning Leo experiences at the Shredder's hand.

Summary
Leo is fine. Despite what his brother’s might tell you, he’s doing great. Sure, he hasn’t quite been himself since Splinter’s death, but he’s adjusting and his brother’s silly little intervention wasn’t going to change that. He tried to tell them as much before the dart pierced his skin and everything went black.
He now finds himself half-way across the world in Japan at the mercy of his unknown assailants. Just as he’s about to give up all hope, he’s saved by a band of Yokai Samurai led by a rather nice white rabbit. He’s not sure how he’ll ever get home, but he trusts Yuichi Usagi to get him there.

maybe you weren't a terrible person by Crowdog

24 May 2025
Summary
Pre-Leotello stories from their childhood, teenhood, and all the way to the moment they lost The Key. These stories explore Donnie and Leo before they are anything more than brothers. Their relationship, their history, and their struggles growing up with a father that tries his best and doesn't always do right by them. These stories are canon to death is our third wheel and it's kinda cringe which follows the Donnie and Leo in the Doomed Timeline that Casey Junior comes from.
