Mondo Gecko is a classic character in the 1987 series of TMNT and a senary protagonist of today's series. He's a mutated gecko who is a good skateboarder (but not a good fighter).


Born in 1995 in New York City, Jason was skateboarding on his own self-made halfpipe when a canister of Mutagen came falling from the Kraang ship, and one of them struck him on the head. Having to have placed pet leopard gecko Lars on his shoulder, he mutated into a 4-foot-tall humanoid leopard gecko and was rejected out onto the streets by his parents. Months past and Jason spent them skateboarding alone in the shadows until one day after the Kraang invasion, he was taken in as an errand boy by Fishface and WOWS Michelangelo with his awesome skateboarding tricks. Jason, nicknamed "Mondo Gecko" from then on, was taught that it’s every mutant for himself, but after seeing Mikey and Casey Jones battle Fishface, who then exposes his true nature by slapping Mondo away, he learns that it is always better to have a friend's back, and so starts the unbreakable bond between turtles and geckos.



He has a typical surfboard person-like Personality (example: saying Dude, Gnarly, Cowabunga, etc) he gets really ticked off when People don't call him by his real name instead of his Mutant Name. From what Fishface has told him Mondo looks out for himself such as when Casey almost fell off a building he laughed and didn't even bother to rescue him (despite the fact that he would've died or become hurt) but after finding out that other people care about his safety (when Mikey saved him from falling off a building) he started to become more cautious
