Rat King

The Rat King remains one of the more enigmatic characters in Teenage Mutant Ninja Turtles, with various appearances depicting him as either a villain, a neutral character and even an ally of Teenage Mutant Ninja Turtles. The Rat King has a distinguishable attire, which consists of filthy, tattered rags and, most prominently, various bandages covering his body. The Rat King has apparent telepathic influence over rats, with his only other consistent power being his immense strength (which varies throughout incarnations of the character).
