Summary
“So, what do we do now?” Knight asked.
“I am so glad you asked,” Mike smirked, rubbing his hands together. Spinning around, he pointed a finger at Purple. “Boss’s Donnie, if you would do the honors.”
Purple cracked his fingers. “Let’s get to work,” he declared before the three Donatello’s descended on their workstation.

Summary
He had a dream that showed him the future? Well, maybe not, because in his dream, he had portal-chopped Raph’s projection’s arm off, and he didn’t do that this time. Though, that may have only been because he was distracted this time.
Leo freezes as he remembers the events that came after that in his dream.
Surely that’s not going to happen, right? I mean, a whole alien invasion? A boy from the future? Him dying?
Dreams sure are weird.
The brothers were lounging in the living room when April ran in, panting. She was dragging someone behind her, seemingly holding a grappling hook of some sort.
The others spring up and begin asking questions, and Leo pales.
He gets up and peeks over April's shoulder and— yep. That’s Casey. Eugh boy.

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
Everything about him looked like Leo, except it all looked more comfortable on the boy, like he wasn’t trying to conform to the ways of a species that didn’t belong to him. He looked good. He looked like he could be happy.
It must be his fault then that the human still looked unsatisfied. After all, he was looking back and seeing a weird green guy instead of himself. That had to be it. He didn’t want to consider the static clinging to his lungs or the way his stomach twisted when he pressed his hair down.

This will be a collection of snapshots connected to my Magic Mirror AU comic on tumblr! Bits and pieces that I’m not sure will make it into the comic, but are important to the plot anyway.

Summary
"What did you do to Leo?" Donnie accused. His voice came out precise and absolutely vicious.
Draxum flinched but held his gaze, a show of respect, scientist to scientist, that Donnie wanted to throw back in his face. "Even with a combination of mystics and science, one cannot truly program a living mind. We can shape tendencies through genetics, lean a brain toward certain temperaments and abilities, but we cannot issue commands." He paused, choosing his next words carefully. "What we can do is lay the groundwork and let the mind complete the pattern on its own."
The connections were forming in Donnie's head before Draxum even finished. Leo's behavior over the years. Beliefs Donnie had never been able to parse. A pattern he hadn't let himself look at directly until now.
Oh god. Please don't let him mean—
Draxum's voice dropped to something just above a whisper. "I needed to ensure the sacrifice would be made. So I introduced what I might call passive suicidality. In retrospect, it was disturbingly simple. Program the baseline knowledge that he was meant to die. Pair it with an instinct toward loyalty, and a drive to win above all else." He paused. "The mind does the rest."

Roots and wires. Stems and conduit. A seed planted and a source code.

Summary
These past few days since his return to Earth have been giving Mikey some serious emotional whiplash, which was to be expected, he supposes; he hasn't exactly been feeling like himself for a while now.
On that note, there's been a more... recent development to his affliction in terms of physical state: unusual pain in different areas of the body (there's this stiffness in his neck that's really bugging him), and an awfully persistent neuralgia that just comes and goes.
A lot more has definitely happened during his time in Dimension X - too bad he can't remember some of it.
-
Basically, fuckass Kraang did Kraang things to Mikey and now he's super traumatized and suffers in a multitude of ways.
This is my first fanfic literally ever so I suck balls please (be patient with me.)

Summary
Being the youngest was supposed to mean that you wouldn't have to worry about your older siblings. But not in this family! Our resident mutant turtle is brothers with Leonardo, Raphael, Donatello and Michelangelo. Those four are going to get themselves into a lot of trouble and near death experienced, but they always make it though.
There will be suprises, some character get more action than before, the magic of this world will be expanded upon and most importantly familial connections will be the thriving force of this story.
---------------------------------
The story follows my original character from start of the series to its end.The 2003 turtles give me huge big brother vibes, so I gave them a younger brother.
(I will add more tags when we get there)

Leo never expected it to come to this. This role he'd taken on.
–
tldr: Leo's late-night outing accidentally leads him to taking on a second undercover identity. Maybe not the healthiest way of coping with the invasion, Leo. -
