Summary
“Let me give you some advice,” Leo said, still so quiet and cold, nothing like Raph had ever heard before, blue eyes burning like fire. “Don’t ever lay a hand on my brother again. I don’t care who you are. I don’t care how big you are. All I care about here is him.”

When I Said I Was Asexual I Didn't Fucking Mean This. by Anonymous
Fandoms: Rise of the Teenage Mutant Ninja Turtles (Cartoon 2018)
06 Mar 2025

Summary
"Asexual reproduction.” Don had replied once out of the blue, his response to Leo's poking and prodding. Tired of Leo’s endless questions. “I’m reading an article on asexual reproduction, specifically on Parthenogenesis”
“Why?” Leo had pried humouring his brother's boring facts at the time. “Also what is that?”
Little did he know he was about to find out a little too personally exactly what that is.
...
..
.“Well aren't you cute” He giggles as it all settles in, a sharp prickle in his throat as he took the time to run his thumb against the side of the shell before speaking. “I will call you green.” He declared setting his child to rest among the stars of his eyes, his anchor, his moon.
The egg doesn't respond, its an egg of course, but Leo blinks memorized at it all the same.

In Which The Author Uses Every Excuse In The Book to Turn A Ninja Turtle Into a Infant/Child by NinjaNekosLibrary

Summary
Pretty much just what the title says. Mainly 2012 turtles, but I’ve got some 2018/2003 in the works. Maybe even Mutant Mayhem one day!
It's a series of OneShots/Drabbles that may be focused more around Donatello than other ninja turtles because I find a mini Dee absolutely adorable!
Feel free to drop requests for him or other turtles as tiny tots and I’ll see what I can do!

What if Miles and Mikey were art friends online but they didn't know the other irl and then one day they meet but still don't know who the other is but they get along instantly?
Idk it's just a silly fun idea I had that I wanted to write about.
Edit: This was meant to be silly and fun but apparently, I can't stop myself from writing angst. So.

Summary
Leo, too busy taking in the wonderful cheers of New York, barely catches the signs. Barely. He’s the oldest, he’s able to figure out his brothers and know their quirks. So when Mikey’s too quiet and Raph’s slowing down… he knows something it wrong.
And then he spots the spider-web-like crack dancing up Mikey’s shell.
Or: Mutant Mayhem missing scene! The boys’ shells were cracked. Let’s address that.

Summary
Leonardo continued, "Even though the city knows about you guys, it’s in everyone’s best interests that we stay unknown. It’s easier not to explain four new mutant turtles to the general public.”
“They’ll think that we cloned ourselves,” Donnie mumbled. “Like Dolly the sheep.”
“And Sonic,” Raph added.
Michelangelo tilted his head. “The hedgehog?”
“No, the fucking honey badger,” Raphael scoffed. “Dumbass.”
“Your ass is dumb,” Michelangelo said, sticking out his tongue. “And flat.”
“You motherfucker – ”
Leonardo held up a hand. “You two can both be dumbasses once we’re back in our dimension, but for now, cool it. We’re on a mission. Act like it.”
Raphael pulled a face, but they both quieted down. Ooh. Leo would have to steal that trick. Maybe it’d work better than the tears that he usually resorted to when the guys got like this. Not that it worked very well.
Or,
5 times that 2012 Leo was the responsible older brother figure that the mm kids needed + 1 time he was the biggest dork in the multiverse

Summary
[MUTANT MAYHEM SPOILERS AHEAD. YOU HAVE BEEN WARNED.]
"What in the..." Leo's crouched position allowed him to take a look at his shell, and he covered his mouth in shock. "Your shell..."
"It's not as bad as it looks," Leo grunted, his expression telling otherwise.
"Liar," Raph said in a sing-song voice- holding tighter onto Mikey and Donnie when he spotted his shell. "...Ah, damn. Your shells look like those Picasso paintings."
"As if your shell is very pretty at the moment." Donnie huffed. And cringed at the sight of Mikey's eyes. "Dude."
"Mhhfff." If he said something, it was muffled by Raph's shoulder.
"Hey- uhm. Turtle dudes?" The four glanced up when they heard one of the humans who helped Splinter speak, awkwardly rubbing the back of their neck. "You need a hospital- a vet? Those injuries can't be good."
Or
The aftermath of the fight against Superfly.
Leo can't seem to relax, when out in the open.

Summary
He was drifting off to sleep, until he heard a ping from his computer. Not wanting to update yet another system, he tried to ignore it, until the pings got overwhelming and frustratedly Donnie opened the computer.
There was over fifty updates for an invite to a knockoff discord server that he had never downloaded.
Virus? Likely, but he had a firewall that outrivaled the Chinese government’s, so he accepted the invitation.
Only to be greeted by chaos.

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.

It had been an accident…or at least, that's what Michelangelo frantically rambled once he ran to find his family after drinking one of Donatello's rejected batches of mutagen.

Lost in Time by Little_Frog_Writes

Summary
A full year passed since the recovery and rehabilitation of the turtles and New York. Weirdly enough the residents of New York were more accepting of the mutants and various yokai roaming the streets. The states were even considering moving forward with citizenship for the honorable deeds that the creatures performed for the human race during those trying times. Although with the new state of New York, crime was not decreased in the slightest, only proving to increase from the numerous new Yokai threats.
All this combined led to this very bizarre situation Mikey now found himself in.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Basically, a Mikey-centric story with a cross-over twist. Mikey is a little bean in this story since he is my favorite! I tried my hardest to portray the turtles close to their tv personalities, but I added my own flair. I have not watched the 2012 series since I was a little tot, so I am going off my imagination for some parts. This story was inspired by Vanilla Vengeance's Mystic Malfunction. It's a good read! Not all chapters will have cover art, but some will. Enjoy! -

Summary
“It’s close enough you guys can visit!” Casey grinned, a hand outstretched in compromise, “But far enough out there where we could just exist without having to only go out at night or-or having to be careful during the day!”
Raph shook his head halfway through the rant and as soon as Casey finished he was up.
“Mikey’s home is here!” His pointer finger tapping on the table in a frustrated way, “You can’t take him away from us!”
Or
Casey asks for Leo’s blessing.
