Summary
As much as Donnie would like to be a robot and simply keep working and advancing, they were cursed with a human body. A human body with emotional and physical needs. Suddenly, their mode dropped, along with their productivity, and Donnie came to the horrifying conclusion that they were lonely. They missed Mikey’s home cooked meals, now sometimes going far too long without eating. They missed Raph’s enthusiasm and spending time with him. They were even loath to admit they missed Leo’s dumb jokes. And staying up late with Leo when neither could sleep. And ranting to Leo about their day. And listening to Leo’s absurd Jupiter Jim theories. And Leo nagging them about wearing their back brace.
God, Donnie missed their twin.
(Or: Donnie suddenly starts struggling emotionally and physically while in college, but it's a good thing Tim likes to insert himself in other people's business! If only he could help with the random seizures and memory gaps Donnie has been having. A story about college, family, surgery recovery, gay idiots, and Donnie being bad at self care.)

Summary
April O'Neil already had to deal with all the mystic shenanigans, now she'd just like to go home. But now she has new allies and enemies to deal with, and her brain might explode if this place keeps being so different.
-
The four mutant brothers were still recovering from trauma and did not have time for more shenanigans after all the goddamn bullshit, it was just starting to quiet down. So why are these people here insisting they're the turtles' friends! Will they be in the future?
-
Turns out avoiding an apocalypse causes some separation anxiety, so when your older sister (basically) goes missing you panic, right? Well join this very lost found family for the "Rescue April" mission! -

Sherlock_Corn🌽:
Alright, team. New group chat. 🎉
Because SOMEONE (glares at Mikey and Leo virtually) kept clogging up the old one with GIF wars. 🙄Neon_Leon💅:
Uh, excuse me, April.
First off, they were strategic morale-boosting visual aids.
Second, my reaction time on that "dog with sunglasses" meme was legendary, tyvm.A chat fic with Leosagi, Timtello, Shellshocked, Aprinita, Rasey, and Raphmona. Filled with fluff and shenanigans with the occasional angst and drama.

Summary
We all know the Teenage Mutant Ninja Turtles. But what if they mysteriously landed not where they should? Were the characters in the wrong story?
I took 12turtle tots and Rise turtle tots and swapped their places. They grew up with different fathers and in different worlds. This fic is both funny and a bit dark. Also theres lots of swearing.

Summary
The 2012 turtles and their Rise counterparts are added to a group chat, and nobody knows who the creator is. They only come on when those of the turtles who aren't going to question them are the only ones online, but seem to be friendly. As these two families talk, new familiar faces are added, and romance occurs.

Summary
Two different worlds. Two different teams of siblings. One enemy that refuses to stay buried.
When Raph vanishes through a crackling portal, her family discovers a nightmare they thought was over: the alien conquerors are back, their grotesque machines spilling across dimensions. A rescue mission becomes a race against time as the turtles search rooftops, shadowed alleys, and hidden realms where mystic power is stripped away — while Raph fights to keep herself from falling into the uncontrollable fury of her Savage state.
But this battle isn’t theirs alone. Another team of turtles, older, battle-worn, and scarred from their own war with the invaders, is pulled into the chaos. Two generations. Two dimensions. And one impossible choice: trust each other, or watch both their worlds consumed.
The portals are opening. The Kraang are waiting. And family may be the only weapon strong enough to survive.

Summary
Raphael is a virgin.
That was made abundantly clear when him and his siblings-turned-partners played a game of Never Have I Ever. Because of course that was the first game Leo wanted them all to play as soon as they were past the awkward stage of realising their feelings for one another.
The question had been something about lying to a sexual and-slash-or romantic partner about your body count, and Leo, Mikey, and Donnie all drank.
Raph did not.
----
Or: Raph admits to being a virgin, Donnie, Mikey, and Leo seek to fix that :)
