Teenage Mutant Ninja Turtles

The Teenage Mutant Ninja Turtles (or TMNT for short) are a team of four teenage turtles and their allies, who were trained by their sensei in the art of ninjitsu and named after four Renaissance artists. From their home in the storm sewers of New York City, they battle petty criminals, evil overlords, the Foot Clan, and Kraang alien invaders, all while remaining isolated from society (for the most part) to make sure that they don't become experimental fugitives.
