Summary
Purple chomped and yanked their head side to side. Their skull was grabbed and their jaw popped open. Another Hand squeezed their arms down and before Purple knew it they felt something squirt out of their tail.
“Seriously? Not you and the snapper!”
“Oh I'm going to pee myself! Great job! Super soldiers that can musk on their enemies!”
“Erg..”
Purple's breathing had rapidly increased. They released something else from between their legs. Something belonging in the trash corner of the cage with Blue. The Hand made another noise and this time Purple was dropped, landing on firm ground with a slight give.
“I was just moving you and your emotional support defect to a new, larger cage. And you poop on me? You poop on the great Baron Draxum?”
“Stop, stop, my sides hurt, ha ha ha ha HA!”

CaptainLeo:
@everyone

I’m so sorry that’s mine
I wondered why he was so quiet~~Electro~~:

This is the third time in four days.
Please control your Mikey or I will have to use force~
In universe 2003, Donnie tries to experiment with the inter dimensional gun the 1987 turtles had given him. Instead, he accidentally creates a multiversal chat room for many different versions of his brothers, and counting.
It certainly makes life…interesting.TLDR: multiverse group chat between most iterations of the turtles. Starts with 2003, 2012 and 2018 but more are added as I go. 50% plot and 50% chaos.
*now includes the 87, mutant mayhem and bayverse boys!*Series

Summary
By eight thirty the lair was running on generator power and Donnie’s ears were ringing so loud he couldn’t even hear the baritone of the motor thrumming out in the open sewers. Note vibrating on the handle because no twin had returned home to rip it off with a roll of his brown eyes before depositing the original propane tank nearby. Donnie couldn’t hear Mikey’s voice as he asked about Leo, he couldn’t feel Raph’s hand as they brought him into the lair to warm up his frozen fingers.
Someone else moved Donnie’s mouth and made his vocal cords vibrate into the open air of their home. Someone else stood in the doorway of their father’s room begging their dad to get out of bed because Leo was missing. Someone else felt the world caving in because all the things that were supposed to be unimaginable were happening right now.
As if panic could knock back a respiratory infection Raph and Mikey hooked the TV up with Donnie’s numb help. The weather report was worse than they last knew. That blizzard that was originally projected to hit tomorrow by one in the afternoon would be here at their doorstep much earlier.

The Doctor and the Ponds stumble across some aliens in New York and team up with some mutant turtles to stop them from destroying Earth.

"Raph stumbled and swore as the room- ship- whatever- shook around them and made a sound like a broken (possibly haunted) washing machine. He gritted his teeth as he tried not to fall flat on his face and noted somewhere in the back of his mind that his brothers and Amy and Rory weren’t fairing any better. You’d think the other two would be used to this by now, if they did this a lot. The Doctor was unfazed by all the commotion, running around the control thingie, limbs going in all directions like a drunk octopus as he piloted the thing. Assuming he wasn’t bullshitting them and they weren’t about to die horrible deaths. With their luck that was still a very real possibility."

Summary
П'ять років тому з-під землі вирвалися давні монстри, які називають себе йокай, і повністю захопили Нью-Йорк, переробивши його під свої потреби. Лідер йокай не збирається зупинятися на досягнутому та мріє завоювати решту континенту, щоб йокай могли тріумфувати, поки люди, які століттями їх пригнічували, корчаться під їхніми ногами.
Для того щоб реалізувати такий складний і амбітний план із захоплення світу, потрібно звернутися до науки. І знайти ідеального піддослідного. Хтось із людського опору, що кидає виклик величі йокай, ідеально підійде.Або
Барон Драксум виростив черепах, і вони занурили Нью-Йорк в апокаліпсис.

Summary
“You may have felt special because Leo is skilled in that- but you were not, you were easy,” Donnie snarled. “I selected you for that reason-”
“Now hold on you sick fucker-”
“No,” Donnie said louder, looking down at Travis now and opening his faceplate to show he was there in the flesh. The reaction was gold. Donatello was performing this live, no longer in stereo from the hanger and speaking through a metal zombie. “See if I was a sick fucker,” Donnie spat, “I might derive some sort of sexual gratification watching my brother fuck only those I allow him to. I might watch him complete that act through one of my many cameras without his knowledge.”
This was what he wanted to spread. His hatred for Leo and their fucked up dynamic. Travis wasn’t mad now, he was scared. Donnie was not angry because Travis landed a hit on his drunk brother, Donnie was angry Travis got in the way of him getting off tonight. “So now that I have made it clear I am essentially the one that pursued your partner through a mindless drunk puppet for my own amusement- where do we stand?”

Summary
Casey is big on physical contact. He’s the kind of guy who shows affection through touch, the kind of guy who communicates with his whole body. This isn’t necessarily a problem. Raphael has gotten used to it.
Except for the part where he keeps touching Raph in ways that set off the turtle side of his brain. Except for the part where all those touches start to make Raph catch feelings. That is a problem.
