The Bad Guys Justice League: Arcadia-Point

Takes place after Trollhunters: Rise of the Titans.

Jim goes back in time to save Toby, and figures he can might as well fix some other stuff on the way. But time is more malleable than he thought, and he soon find there are things outside of time that he cannot predict, nor control. His new timeline of reality has no meta-humans! No superheroes! No defenders to protect the world! And while he entered this round with a cheat sheet, someone seems to be changing the rules around him. He now must fix everything before he and his friends run out of time.
