Teenage Mutant Ninja Turtles

Teenage Mutant Ninja Turtles (TMNT) is an American media franchise created by Kevin Eastman and Peter Laird, beginning as a self-published black-and-white comic book in 1984. It follows four anthropomorphic turtle brothers -- Leonardo, Donatello, Raphael and Michelangelo -- trained in ninjutsu by their rat sensei Splinter, fighting crime in New York City. The franchise expanded into hugely successful animated series, live-action films, toys and video games and remains one of the most recognised properties in comics (Wikipedia)
