Summary
The last of Casey Jones' family died less than 48 hours ago. Now that the world isn't about to end he may need to start processing that, but that's hard and it's easier to pretend everything is okay. Being the only one to remember the last war to ever happen is totally okay. To be a sixteen-year-old war veteran is totally okay. To be face-to-face with the younger versions of your deceased family and realize as much as you love them you are just the cool guy they just met, is totally okay. Yeah. Yeah. Casey Jones is totally okay.

Summary
It's been years, decades, since the Kraang split the sky and rained down death and destruction, but they still live on. They still fight.
But no matter what they do, no matter what- who they sacrifice, the Kraang always seem to come back stronger.
It may be time to try something different, a last resort. Something that won’t save their world as it is, but stop this carnage before it could even begin. At the very least, Casey will be safe, right?
tldr: Casey Junior’s original timeline, and what led up to Master Leonardo tossing him through time and space with only a faded photo and a frantic plan. And then, the aftermath of that choice.

Summary
Title inspired by "Medusa", by Kailee Morgue.
A choose-your-own adventure, where you are Lita, the next generation of the mutant turtles, growing up in an alternate timeline based off of Cass's Apocalyptic Series. The path is decided by you: do you duck and hide? Do you attack? Who saves your life at the cost of their own? Who is your father? Will you really go through the movie as canon? All these choices and more are left up to you. How will this world change with you at the wheels?
I have no idea what I'm doing.
