"Our Sensei Ninja Turtle" Masterpost

Hello! this is my OSNT au masterpost where i shall organize my chaos! to anyone who is just finding this, ill give u a little overveiw of the universe ive created:

Leonardo is supposed to be dead. the rest of his family is dead. His brothers, his father, his sister... He failed over and over and they were the ones who paid for it. so he did the right thing, sending Casey back to that dreaded day to stop the Kraang invasion with leo staying behind to be sure his kid got through. and to maybe finally find some sort of peace away from the broken world he created.

But Leonardo is not dead. He wakes up in the hidden city of all places, untouched by the kraang and full of life he never thought he'd have the privilege to see again. and on top of that, he happens to stumble across four small turtle mutants. And maybe hes just finally lost it, but hes preeetty sure he somehow transported himself to an alternate reality of his world where some things are the same while others a vastly different. This is what happens when you listen to enough of Donnie's theoretical monologues, you start to think up some crazy conclusions.
