The Teenage Mutant Ninja Turtles, often shortened to TMNT or Ninja Turtles, are
a team of four anthropomorphic turtle brothers named after Italian Renaissance
artists: Leonardo, Michelangelo, Donatello, and Raphael. Trained in the art of
ninjutsu by their rat sensei, Master Splinter, they dwell in the sewers of New York
City, surfacing only to fight against evil forces ranging from petty criminals, alien
invaders, to mutated creatures. Known for their love of pizza and their distinctive
colored masks - blue, orange, purple, and red - they navigate the challenges of
teenage life while also working together to protect the city and its inhabitants.
