TMNT Fanfiction Masterpost
General Audiences:
A Mischief of Rats = Multiverse Crossover (Other than Lou Jitsu/Draxum, no pairings)
After a portal mishap, the Turtles from 1987, 2003 and 2012 find themselves inside the 2018 Turtles Lair. This would just be another Tuesday for most of them, except that unlike the previous situations, this time their rat Senseis/Fathers have been pulled through the portal as well. In this story, we will be focusing on the Ninja Masters 🐀
Mama Raphie = Multiverse Crossover (No pairings)
It was supposed to be a social visit with no incidents (well, as much as Turtle LuckTM would allow). Of course, they should have seen this coming. Alternate title: "What to do when a dimensional alternate of your brother believes you're his baby."
Strangers in a Strange Place = 1987 TMNT (No pairings)
At the surface, everything was the same as always. April was annoyed at her boss, but nonetheless following a story, the turtles were tagging along for her safety (and honestly because they had been bored), and the feeling of excitement at going somewhere new filled the air. But then, why did Raphael have a bad feeling about this place?
Casey's Adventures in Reptile Husbandry = 2012 TMNT (Jonatello/CaseyTello)
While checking out the local pet store on a whim, Casey sees a little tortoise being neglected and impulsively buys it. Now he has to learn how to take care of it, taking pointers from the guy he's been crushing on for ages. The fact that said guy he's been crushing on is a turtle himself complicates things.
Teen and Up Audiences:
Shades of Blue = Multiverse Crossover (self-cest, t-cest)
Waking up in a strange place with a splitting headache and no idea how you even got there is bad enough. Finding out that there are multiple versions of you and that the multiverse is real isn't helping.
A Fated Meeting = 2003 TMNT/Usagi Yojimbo Crossover (LeoSagi, katanashipping)
Leo's been stuck in this strange dimension for six months now. It's a version of Japan's Edo Period, except that instead of humans, they're all animals. One day, the routine he has fallen into is interrupted by the unexpected sounds of gunfire. Little did he know that fate had plans for him here.
How NOT To Acquire A Child 101 = Multiverse Crossover, Leonardo-centric, specifically 2012 Leo (No pairings)
While hanging out together, the Fearless Leaders find something unexpected.
Mature:
Waking Nightmare = 2012 TMNT (no pairings)
After a recon mission goes horribly wrong, Leonardo is forced into an agreement to save his brothers's lives. Now if he could only survive his new Husband's plans until rescue comes.
Explicit:
Riding the Purple Monster = 1987/2003 TMNT (t-cest, L/R)
That was not the kind of evening either of them were expecting, but they weren't going to complain.
A Promise Made is a Promise Kept = 1987 TMNT (no pairings)
After what was supposed to be a simple supply run goes awry, a pair of enemies have to band together in order to get back home.
Damn Nature, You Scary! = 2012 TMNT (t-cest, OT4)
Turtles, especially male turtles, when they reach puberty, tend to get aggressive. It's the reason why you can't have a bunch of males together when it's mating season. They might actually try to kill each other. But Leonardo thinks he has a solution, and this season he will put it to the test.
In Another Universe = 1987/2012 TMNT (t-cest, self-cest L/L, R/D, R/M, D/M)
The 1987 Turtles decide to pop into the 2012 Dimension for a vacation. They didn't have the opportunity to explore, what with the whole "The universes are going to be destroyed" thing, so they're making up for lost time. They definitely don't have ulterior motives. No siree 👀
