Leatherhead is a fictional character in the Teenage Mutant Ninja Turtles series. He was created in 1987 by Mirage Studios artist Ryan Brown, who also went on to create the Saturday morning cartoon series Wild West C.O.W.-Boys of Moo Mesa for the ABC television network. Depending on the origin story (the original and Archie comics origins differ tremendously) he is either a mutated, anthropomorphic alligator combined with Human DNA or the exact reverse and appears in all TMNT versions except for the movies and live action series.
