Summary
Leo will be fine. Sure, he may have a big hole in his chest, and he’ll probably be out for the count for a while, but he’ll recover. He just hates that his brothers will be the ones to pick up his slack. He can only hope they’re strong enough to face the Godless on their own but he supposes it could be worse. He could be stuck in Neo Edo all alone, but thankfully he has Yuichi to keep him company. It won’t be all rest and relaxation, however. They still have the Council to worry about.

Summary
“NOW! DO IT NOW!” Donnie screamed.
Orange energy blasted out of Mikey, pulling something red and wispy and flickering out of Raph’s red body, Red, covered in red, liquid red, a red flame flickering—
Mikey raised his hands and slammed them down.
An explosion rocked the lab. A wave of ninpō blasted Donnie into a back corner, where his battle shell barely caught him before he could slam face-first into his circular saw. The lightbulbs burst in a shower of sparks. Every one of Donnie’s purple screens winked out of existence, and when the orange energy dimmed, everything fell…quiet.
Donnie breathed, staring down the serrated blade, mind racing, racing, stuck, stuck in a—in a—in a loop—
“Mikey?” he heard Leo whisper from across the room.
AKA - The Hamato brothers deal with losing one of their own not once, but twice during the apocalypse.

Summary
The 100-day live is supposed to be a celebration, cake, cameras, laughter, everything in its place.
But some things slip through the cracks.Xinlong grows quieter as the night goes on, holding himself together just long enough for the cameras to turn off. Leo notices the heat beneath the studio lights, the pauses that last a second too long. What follows is a long night of fever, unspoken fear, and care given in small, steady gestures.
Between roommates who know when to push and when to stay silent, members who linger without crowding, and Leo who finally lets himself break in the dark, the night passes slowly, until morning comes soft and forgiving.
Sometimes comfort isn’t loud.
Sometimes it’s just staying. -

Summary
Listen, little brother.
You do not earn the sunrise by being good.
You do not earn the air by deserving it.
So why do you think a brother’s love must be earned?When he stumbles, you do not ask why.
You catch him.
Not because he is perfect,
But because he is your brother.When the world does not understand you, I will stand in your corner.
When you do not understand yourself, I will hold the mirror of your worth.
And when you forget your name, I will speak it for you.It is the blanket in the cold,
The shared silence that needs no words,
The hand on your shoulder that says,
“Breathe. I am here. We are here.” -

Summary

Summary
IMDb: When the Turtles discover Bigfoot in the woods, Donnie befriends it and insists they protect it from a hunter.
Improved: When Donnie and Mikey discover Bigfoot in the woods, Donnie befriends her and insists they protect her from a prowling hunter. As they soon learn, Big Foot wants much more from Donnie than his friendship.
(This IS a non-con story and there IS sexual themes, but sexual intercourse never takes place. This is an exploration of the scenario that the episode sets up (and then ignores) on the topic of grooming. The SA depicted is not glorified or appraised in any form. This fic is better categorized as horror. If you're looking for romance, you're in the wrong fanfic.)

Summary
Under the Stage Lights is an alpha-drive K-pop BL AU centered on the intense, unspoken pull between Leo and Sangwon. Leo, controlled and dominant as the group’s leader, struggles to contain instincts awakened by Sangwon’s quiet defiance and deliberate closeness. Their relationship builds through charged rehearsals, lingering stares, and moments where authority blurs into desire, forcing Leo to learn that true control comes from trust, not restraint alone. Sangwon, unafraid to challenge him, seeks not dominance but to be chosen willingly, turning tension into mutual understanding and protection.
Alongside them, Jiahao and Anxin form a softer counterbalance. Jiahao’s watchful nature meets Anxin’s calm steadiness, and their bond grows through gentle touches, shared silence, and emotional safety. While Leo and Sangwon burn with intensity, Jiahao and Anxin ground the story in quiet intimacy.
With the rest of the members remaining in the background, the story explores instinct, consent, and closeness under the pressure of idol life, ending with both couples finding balance, trust, and chosen connection.

Summary
There’s always been discourse in the family.
A distant father, a bossy leader, a mopey hothead, and an annoying little brother. That’s how it’s always been.
At least, as far as Splinter’s sons are concerned.
Why burden them with what they can never have?

Summary
Leo watched him awkward. Instinct told him to try to relax and make a joke, but something made him feel that this one would not be well received.
"Don't worry, big brother," said the one in red bandana.
(And something in that sentence was wrong).
"You'll get your memories back and then we'll all be training together again, you'll see" he told him with a confident smile, looking like he believed every word he said. But faltering at the end of the sentence, showing a bit of his doubt.
Leo tried to smile back, only ending with a strange grimace.
Everything was wrong, his body was wrong. And even though he didn't know what was going on, he was just sure that those people were not his brothers.
O
Rise and 2012 Leo change dimension. The problem? They both have amnesia, they are in each other's body and they both just woke up from their respective coma.

Summary
Being the leader has always put Leo in the spotlight — but when the Foot Clan realize taking him down is the fastest way to break the turtles, Leo becomes their number-one target. A mystic curse leaves a mark burning across his shell, designed to weaken him with every fight, and the enemy taunts that if the head falls, the body will follow.
But the Foot didn’t count on one thing: Leo’s brothers don’t crumble without him. They rally, they fight, and they protect — because no one gets to break Leonardo. Not while Raphael, Donatello, and Michelangelo still stand by his side.

Summary
It's been years, decades, since the Kraang split the sky and rained down death and destruction, but they still live on. They still fight.
But no matter what they do, no matter what- who they sacrifice, the Kraang always seem to come back stronger.
It may be time to try something different, a last resort. Something that won’t save their world as it is, but stop this carnage before it could even begin. At the very least, Casey will be safe, right?
tldr: Casey Junior’s original timeline, and what led up to Master Leonardo tossing him through time and space with only a faded photo and a frantic plan. And then, the aftermath of that choice.

Summary
Meet Caitira Nic Ruaidhrí: Witch, Huntress, and unabashed Geek Girl.
After chasing Cassius Malack, a dangerous magical criminal, to New York City, Caitira meets four unusual brothers whose goals align with her own. She soon realizes that working with Leonardo, Donatello, Raphael, and Michelangelo may be her best chance for victory. But defeating a murderous Warlock won't be easy, especially now that Malack has taken control of the Purple Dragons. In the power vacuum left by the fall of the Foot Clan, the Dragons are becoming stronger every day, and it looks like their new leader may have especially wicked plans for the gang. If Caitira and the Turtles don't discover what he's plotting soon, it could spell the end for an entire city.
As the plot thickens, so do the desires and tensions between Caitira and her new companions. What began as a mere alliance may quickly become much, much more.
The Ninja Turtles in this fiction are influenced by various versions—TMNT 1990, 2003, 2012, Bayverse, and IDW—but they have been aged forward. They are fully adults, people! I don't own TMNT. Any similarities to real persons are unintentional.

Summary
The foot never used human ninjas anymore, so when Leonardo looked up in to the dark brown eyes of the young human foot soldier, he froze. He hesitated. The soldier smirked, his brown eyes looking behind Leo at Donnie and then disappearing behind the scope of his gun.
“LEO MOVE!” Donatello screamed and barreled in to his left side, sending them both flying and skidding across the rooftop.
The gun’s single blast exploded like a bomb.
That shot would have blown him to bits.
**This work is being re-written as another separate fic. I am leaving this up as the super og draft. Hope to see you there soon! 16/09/2025**
Donatello is captured by the Foot Clan after a vicious attack out on patrol, but when he's found in a Kraang base, the traumatized team is left to piece together what happened as Donnie's behavior at home spirals out of control.
