Summary
It hasn't been long since the Kraang and everybody's wounds is still very open and inflammed.
Raph has a small chance of getting permanently blind in one eye, Donnie hasn't really been talking, Mikey's hands are shaking and Leo's got a terrible looking crack on his shell, hasn't been walking right and developed an alcohol addiction to cope with... well, everything. Oh, and he's clearly got PTSD.
Leo is terrible at communicating, but it gets so much worse after he refuses to admit he's got a drinking problem.
This is one of those kinds of stories. -

Summary
“There’s a gentle touch on his shoulder, and despite how much it shocks him he doesn’t react. He… he can’t feel his body anymore, his brain stuck between states of being. He can’t hear the muffled noise from the world, but he can vaguely see Raph in the center of his vision, speaking.”
—————
Leo struggles with keeping himself tethered to reality. Sometimes his family is there to keep him present, sometimes they are not. Here are a few snippets of awareness he has.

Summary
Time ticks by.
Minutes turn into days, weeks bleed into months.
Seasons come and go like the ebbing and flowing tide, bringing with them change as the years pass by.
Wounds heal, scars fade, along with memories.
Some disappear and some stay with a person for life, changing them like the shifting seasons, bringing out the best in some...
but the worst in others.
~~~
Years after the krang invasion Leo is attacked and sexually assualted by a genius he has known for a long time, who learned how to not only grow krang tendrils in her lab but also how to take control of them to make them do whatever she wants. His morally ambiguous twin brother seeks revenge - and what better way than to attack a person's psyche?
Non-con is implied, this au deals mostly with the aftermath.

Summary
"You're a coder, huh? Is it some hobby or do you work in tech," She asks, snaking an arm around Donatellos hand. Over his hand. On his tech. It feels.... intimate. I mean sure Don has been flirted with before but this feels different.
He can't decide if he loves it or hates it.
The hand that was around his own hand snakes gently up to his bicep, and she gently grips. Feeling the muscle that came from years of ninja training under skin.
(Is a spin-off sorta of another work but you don't need to read that to understand this)

Summary
“Irrealis moods are a category of verbal moods that indicate that certain events have not happened, may never happen, or should or must or are indeed desired to happen, but for which there is no indication that they will ever happen...all best expressed...as the might-be and the might-have-been.” – André Aciman, Homo Irrealis.

Summary
Leadership has its weight—but for Leonardo, it’s starting to crush him.
After a harrowing nightmares where he fails to protect his brothers from any sort of danger, Leo becomes increasingly overprotective, watching over his family with relentless vigilance. Every mission, every shadow, every sound could mean danger, and he’s determined never to let anything happen to them again. But obsession comes at a cost.
As Leo pushes himself beyond his limits, the line between protector and prisoner begins to blur. When a brutal encounter leaves him with an invisible wound—something he hides even from his family—Leo begins to question his own place on the team. Can a leader still lead if he's no longer whole? Or will his silence become the very thing that drives them apart?

Summary
No one can remember Leo. Not his friends, his enemies, or even his family. Stuck with almost no answers as to how this happened, he must convince the people he holds dearest of his existence and recruit their help in fixing this mess. Although, not everyone maybe as accepting as he'd thought.
And the knowledge of a time limit leading up to him disappearing forever isn't making it any easier.

Summary
Leo was okay.
Sure, he was having nightmares every day, and he had been avoiding his brothers like the plague, especially a certain purple individual, but hey, at least he was finally stepping up as a leader, right?
Okay, maybe he wasn’t doing amazing, but it's not like it was anyone's business!
or:
After the Kraang invasion and another failed mission because of Leo, he finds himself wishing for things to be as simple as they once had been. But sometimes our wishes are granted in the most unexpected ways, only to come back and bite us in the ass.

Summary
Leo honestly thought he would die in the prison dimension. He didn't expect Mikey to be able to open a portal. He didn't expect Raph to reach out and grab him. He didn't expect Donnie go in for kill on Kranng Prime, reaching out from behind him.
Though maybe he should've expected it. Though what he definitely didn't expect was for his own Ninpo to flip out. (Which was not in anyway connected to him. No siree, nope, not at all.)
He definitely, DEFINITLY, did not expect to be thrown into another dimension. To lose two feet in height. And for all of his memories to be jumbled up and made practically useless. Whoopee...what a...great start to the day. Now he just needed to remember where Mikey and Raph went...

A 2003 - Rise crossover. Because there aren't enough in my opinion and certainly not enough that are to my taste. Enjoy.
