Picture this if you will
The end is near, the Kraang decimated most of the world's population, but Raph got an idea.
If what Donnie said about the Multiverse is real, then they can save the remaining survivors.
Again I have never watched TMNT 2012, but I know theirs an apocalypse episode.
A place for them to go wasn't overpopulated, and they won't be too questioned.
They head to the Mutant Apocalypse episode.
They create a bomb out of the portal to go off the moment they get close big enough to take out half the world.
(They don't know, but they killed all three leader Kraang but the world is inhabitable now.)
They make their home underground, away from the sun and many dangers.
Many humans, April and the Casey's, went mutant...
Raph and Leo both lead, they protect as Donnie and Mikey create.
They announced they were going by new names.
Angel, Donald, Leon, Michael, Cass, CJ, and Krepe.
(This is after the group finds the Oasis but so it'll be a while til they meet.)
Everyone and everything is thriving, Casey is growing healthy and this world provides both safety and danger which is nothing compared to Kraang.
12!Raph is the one to find them, he's suspicious but their not messing with anyone.
He tells his family and they all investigate together.
They don't find the resistance immediately, they find a young Casey Jones.
Casey is frightened at first but soon was set at ease by Mikey, who took charge.
Leon found them before Casey could lead them anywhere and force them to state their business.
They'll probably be allies but that's all I got.
