Leatherhead

Leatherhead crashed onto the scene in 1988, debuting in Teenage Mutant Ninja Turtles #16 from Mirage Studios — the scrappy indie publisher that gave the world its favorite pizza-loving reptiles — created by Mark Martin. A product of the Copper Age's bold, anything-goes spirit, this mutant gator shares the page with Donatello, Leonardo, Raphael, and Michaelangelo, running in the same wild, black-and-white underground tradition that made Mirage's TMNT universe so beloved. Leatherhead's presence extends into Mighty Mutanimals, suggesting a character with enough personality to anchor stories beyond the Turtles' own title. With only a handful of catalog appearances, every issue featuring Leatherhead is a genuine collector's find from a fascinating corner of the TMNT mythos.
