Shredder is the hideous, gruesome and all-around bad guy leader of the Foot Clan, an organized band of evil Ninjas. This low life came to power when he betrayed his Ninja master, Hamato Yoshi (now Splinter). Shredder wants nothing more than control of the world, and he'll stop at nothing to get there even if it means grating his victims like cheese with his razor-sharp armor! , , Turtles, which he means to destroy. Shredder fights a never-ending battle against truth, justice, and the American way. Basically, he's not a nice guy.
