Summary
Rewritten Chapter 1!
A void has existed long before time.
This void was pitch black and rested between death and the living.
This vacant plane of reality was destined to be empty for all eternity.
But slowly, its fate twisted until the destiny became futile to truth.
Four colors began to glow in the void, a glowing orb of blue, red came after, then to be copied by purple, and then, at last, orange.
The colors shone with great brightness, a blinding sight.
Each vibrated with a unique personality.Blue was the leader, caring and loyal, but he's burdened with perfect expectations.
Red was strong, a tsundere on the inside. Yet, cursed with the overwhelming weight of being the family protector with anger issues.
Purple was a genius, determined with fascination, yet, a lot of stress was put on the kid by demands to fix things.Orange was last, the light in the dark void. He'd enter a room and shift the mood instantly. His optimism never halts on a mission. He's too bright for one to comprehend.
He wasn't the one that people wanted to, or assumed to flicker away...Series

Summary
Leo wanted to stand there with his brother, gaze into the beautiful lights that almost seemed to gaze back. When Leo thought of a perfect world, it was just this: his brothers happy and free, under the stars. He forced himself to look back down at the ground.
or:
Role swap AU where Oroku Saki is mutated into rat, and Hamato Yoshi is head of the foot clan. But this story isn't really about them. It's about four brothers, living in the sewers with their sensei.
Not based on any iteration in particular, but perhaps closest to 2012.Series

When I Said I Was Asexual I Didn't Fucking Mean This. by Anonymous

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.

Summary
The sun was clouded by the dust filled sky, the ashy cloud of smoke framed the technodrome while it slowly drifted from its original position, chunks of its Hall had ripped off and were now colliding with nearby buildings and the empty streets of the recently invaded New York.
Donnie stood there, his body firmly planted on the ruined ground of staten island, gazing up at the clean slice taken through the ships top, not even bothering to care about the cropped ship, more then the faded outline of the portal once there. His twin. Gone? Like that? Just.. Instant, it hadn't even set in yet, no realization past his glazed over eyes.
Gone?.. For real?.. No.. This has to be a.. A joke.

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
“Why did I say that,” Leo mutters. It doesn’t sound like a question.
Donnie answers anyway. “Because you’ve refused every single one of my attempts to get you into therapy. Telehealth exists, Nardo. We’re on a very good insurance plan.”
“Since when do we have insurance?” Raph says. He’s peering out from under the overhang into the rain, like maybe Mikey’s going to make a surprise reappearance. “Are you frauding some sleezy millionaire again?”
“Just doing my part,” Donnie says mildly.

Summary
Leo doesn't move like he used to. Mikey notices these things. Always has. The way his oldest brother flows through combat now. How he processes threats before they manifest. How his blades find paths that makes Mikey's breath catch. Tonight's mission should have been impossible. Too many enemies, too many variables, too much that could go wrong. But Leo made it look easy.

Summary
Don's hands didn't shake as he cleaned the wound on Leo's shoulder. They never did anymore. "You could have called," he said quietly, focusing on the neat row of stitches he was placing. "When you first spotted them." Leo remained perfectly still under his brother's ministrations, "There wasn't time."

Summary
Leo flinched. Actually flinched. Too far. But right now, Raph didn’t care. "Five months." Raph's voice broke, "Five months of not knowing if ya were alive or dead. Of finding empty labs with ya blood on the floor. Of…" He couldn't finish. Couldn't voice the horror of those endless months. Of knowing exactly what Bishop was capable of. And being absolutely helpless when it mattered most.

"Ya had a death wish!" The words exploded out of Raph before he could stop them, "Runnin’ in there alone. Again. Takin’ on twice as many as ya could handle. Again." Leo's jaw clenched, "Someone had to-" Raph cut him off. "Had to what? Had to be the sacrifice? Had to prove something?" "Had to keep you safe!" The words tore from Leo's throat, raw and jagged. The silence that followed was deafening.

Summary
Everything felt wrong today. Leo had woken at 3 AM, heart racing from dreams he refused to remember. The lair's familiar shadows had seemed deeper, darker. Wrong. By morning practice, his skin felt too tight. Like it didn't belong to him anymore. "Raph, your guard is dropping." The words tasted like copper in his mouth, "Focus." A muscle jumped in Raph's jaw, but he adjusted his stance without comment. Wrong. Everything was wrong.

Summary
After the events of “A Big Blowout”, the turtles agree to assist Bishop in cleansing the city of what’s left of Kraang chemicals and tech before any unsuspecting humans can stumble upon it. Along the way, they come upon a hidden base that isn’t as empty as it should have been, and obviously, battle ensues.
Other than Donnie getting knocked into a table of the Kraangs’ latest experiment, it goes without incident, and the brothers return to the lair, mission successful! Eager to examine his alien prizes before handing them over to the Utrom, Donnie disappears into his lab, and his brothers head to bed. Everything is normal…
…Until it isn’t.
Screams awaken the lair, and frantic brothers follow them, horrified to find an infant Donatello sobbing his heart out on the lab floor.
Several hours later, Bishop reports that they might be able to reverse the change, but there will be no way to return the lost memories. And so, the brothers are faced with a tough choice.
Introduce a stranger, or raise a brother.

Summary
Leonardo, Raphael, Michelangelo, Donatello and their best friend April meet a vigilante called Casey Jones. They aid him in his crime fighting, mostly to keep him quiet about their existence. However, they start to learn more about their clan and each other as they delve deeper into New York’s criminal underground.
-
Warning: This series does start out more light-hearted but will eventually delve into themes of religious trauma, cult mentality, ableism, abuse, homophobia and transphobia, disordered eating, ect. Some of these themes are present in subtle ways from early on. If you do not think you can handle these subjects, please do not read. I appreciate your interest either way.

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! -
