In 2003, 4Kids and Mirage Studios joined forces to bring those heroes on the half-shell back to TV… but this time, they mean business. This Teenage Mutant Ninja Turtles series was inspired by the original, darker and edgier comics that made their debut in 1984. With significant input from Teenage Mutant Ninja Turtles, co-creator Peter Laird, the episodes are based on those early storylines and a graphic visual style comic fans love.
