Teenage Mutant Ninja Turtles

The Teenage Mutant Ninja Turtles (TMNT) or just Ninja Turtles are a group of four fictional bipedal humanoid talking turtles, practicing ninjutsu. They are named Donatello, Leonardo, Michelangelo and Raphael, after European Renaissance artists.

Guided by a rat sensei named Splinter, their usual hideout is located in the Sewer System of New York City. Their best Human friends and allies are a woman named April O'Neil, and a crimefighter named Casey Jones.

Originally created as comic characters by Kevin Eastman and Peter Laird in November 1983, and the first comic debuting in May 1984, their success later spawned several television series, movies and action figures. Their major popularity peaked in the late 1980's and early 1990's.

Because of censoring reasons, they were earlier known as the The Teenage Mutant Hero Turtles (TMHT) or just Hero Turtles in the United Kingdom and some other countries.
