Do You Think Body Swapping For The Day Will Count As A Business Expense? by Conartist170

Summary
Donnie doesn't know where he is. This certainly isn't his body, his clothes and its certainly not his lab. He's never been in a human high school before. Not like this anyway. Not as a student.
He doesn't know what he's doing and he certainly doesn't know how he's supposed to do it, but he will absolutely do something impressive before he lets himself be gunned down by social anxiety.
-
Mutant Mayhem Donnie and Rise Donnie swap bodies. Neither really has a good time during it.
Or, I like body swapping stuff and I like Donnie. This was the obvious conclusion.

The Memories of A Trans Bitchass by Anonymous
Fandoms: Rise of the Teenage Mutant Ninja Turtles (Cartoon 2018)
06 Feb 2025
Tags
Summary
Some memories that I, a Leonardo fictive in a system, can remember of my personal canon. (Some of my brothers who followed me here may also write some things, but it's mostly just me here cause I'm ✨special✨ like that.)
Some of these will be kinda awkward and strange to those who are human, but, for me, it would be about the equivalent of talking about a uterus-haver's period or talking about a trans person's experience with gender affirming care. You can uh- probably tell what some of it's going to be about, at this point, but I hope you also see my point.
I'm posting this here on ao3 (without the name of our account but still-) to kinda help me process these memories and also get used to the fact that I won't really get to experience similar things anymore.
It also kinda helps that people might enjoy hearing/reading about the stuff I remember, and that makes me pretty happy.
Uh- anyway, hope you enjoy this ig?? idrk, it's midnight rn and I'm tired-Series

Summary
Leo always felt a different from his brothers.
He was stronger, faster, and more violent than his brothers. Unlike his brothers, he was a natural-born fighter. Thankfully he was good at hiding it.
Everything was fine until he did something he'd forever regret and lose the trust of his brothers.

Summary
Lavinia’s heart stopped as she looked at the rabbit’s face again. She knew those white, fluffy ears, that haunted look. It couldn’t be.
But she had no time to process the shock as he lunged forward, katana raised, his eyes hard and unyielding. Lavinia barely managed to raise her blades in time, the clang of metal against metal ringing out as she blocked his strike.
“Wait!” she shouted, her voice laced with desperation, but the rabbit’s face remained blank, his grip tightening as he pressed his weight against her. He pulled back and struck again, his movements fluid and practiced, forcing Lavinia to step back as she deflected his blows. “I don’t want to fight you!” She dodged his next swing and quickly put distance between them.
The rabbit stopped his advance, his head tilting ever so slightly as he studied her. There was a flicker of recognition in his eyes, but it was buried under a hardened resolve.
Lavinia lowered her sword, taking a cautious step forward. “Three… I remember you,” she said softly, her voice barely audible above the crowd. His eyes narrowed, his stance rigid, but he didn’t attack. Lavinia took a deep breath, her gaze steady. “I’m going to get you out this time. No matter what.”

Summary
The headphones were tossed onto a work desk without care, crashing into the surface with a rattling clang. The sound echoed in the quiet chamber, and Leo flinched as he brought both hands to his tympana. His eyes were screwed shut, lips pressed tightly together. After a moment, though, he cracked one open. The next followed as he stared wordlessly at Splinter and the rest of them.
Splinter opened his arms. “Leonardo, my son – ”
“Ahem.”
Leo was off like a shot. He scrambled to his feet in such a wild motion that he smashed into a table, pushing off of it as soon as he collided. Beakers and bottles and all sorts of sciency shit smashed into shards. Between one heartbeat and the next, he was on his knees, shell to them, facing Shredder.
Raph felt his stomach turn.
or, the aftermath of the almost four months Leo spent with the Shredder. Conditioning and sensory deprivation has done its job and turned him into the loyal son the Shredder asked for. The Shredder couldn't be more content, really. Raph, Donnie, and Mikey, by comparison, are sickened by what their enemy has done to their brother.
Leo is just scared.

Summary
Leo holds up his hand to show the gem to his brothers, but in doing so his thumb presses down in the middle of the gem. A bright flash blinds him as he stumbles back and drops it. He rapidly blinks the spots out of his eyes.

But instead of hearing the groans, disappointed sighs or even the rare giggle at one of Leo’s jokes, there’s nothing.
They’re frozen.
---
Leo and his brothers get back from a mission with mysterious gems and Leo somehow pauses time. His brothers are like statues and he has to somehow find a way to unfreeze everything, but he may not be as alone as he thinks he is.
