"Turtle power!" The Teenage Mutant Ninja Turtles (or simply "Ninja Turtles," abbreviated "TMNT," and officially known in the United Kingdom as "Teenage Mutant Hero Turtles") are a fictional team of four anthropomorphic turtle mutants - Leonardo, Raphael, Donatello, and Michelangelo - who are trained by sensei Master Splinter to become skilled ninja warriors. From their home in the sewers of Manhattan, they battle petty criminals, evil megalomaniacs, and alien invaders, all while remaining isolated from society at large. These appealing characters initially appeared in comic books before being licensed for toys, cartoons, video games, and film adaptations. Shop here for toys, action figures, and vinyl figures featuring the Ninja Turtles, their plucky human companion April O'Neil, The Shredder (villainous leader of the Foot Clan), and others.
