ROTTMNT: World of Mutants

It's been a year since the Krang were defeated, three since the Shredder was destroyed. The Turtles have been sitting idle for the most part. Until Raph meets a girl who brings their attention to a new threat; a scientist with the means and want to mutate the whole world. Together with their allies, old and new, the brothers set out to stop this madwoman before the world as they know it is brought to its knees.

This will be written in episodic format, meaning each chapter will be an 'episode' and have it's own title. Some mature themes may be included, but nothing explicit.
