Fan Casting Mondo Gecko in Teenage Mutant Ninja Turtles: Mutant Warriors

Jason Eastman was an ordinary kid with his pet gecko Lars, until the day a canister of mutagen happened to make contact with him, turning him into a humanoid gecko. This led Jason to be abandoned by his parents, taking on odd jobs for criminals to make ends meet and live. Eventually, Jason got tricked by the Foot to fight the Turtles, but he ended up befriending them, with Michelangelo nicknaming him Mondo Gecko. Now, Mondo is part of the Mighty Mutanimals and a good friend to the Turtles, especially Mikey.
