Keon Jason Allen (The Next Chapter)

Jason, also called Mondo Gecko is a classic character in Teenage Mutant Ninja Turtles: The Next Chapter. He's a mutated Tokay gecko who is a good skateboarder (but not a good fighter).
== History ==
Jason started his life as a human 50-year-old boy playing in the local metal band "Merciless Slaughter," which alerted the Turtles as the noise came from the Shredder's hideout. When the Turtles see the metal band practicing they decide to intervene as trespassing not only illegal, it is a bad idea, considering it was Shredder's territory and danger could be about. Sure enough, the band accidentally activate some dormant Foot Soldiers and are attacked. Mondo accidentally got mutagen on him and because his latest contact was with his pet lizard he carried on his shoulders, his skin started turning green and his rear end sprouted a tail that ripped through his jeans, transforming him into an anthropomorphic gecko. His girlfriend, Candace Fine, decided to split up with him, and Mondo accepted, knowing she could not handle him as a mutant, and the two parted ways peacefully. From then on, Mondo accepted the name Mondo Gecko. The Foot Clan took Mondo under their wing and told him that four Ninja Turtles were the reason that Mondo was mutated. Mondo then blamed the Turtles for Candace breaking up with him, joining the Foot Clan and being taken care of by resident scientist Baxter Stockman.
After he learned that Baxter Fly was evil, he became an ally of the Turtles, even helping the Turtles take down the Shredder. After the Turtles defeat Shredder, Mondo and the rest of the mutants went to go live with April O'Neil, the Turtles, and Splinter in April's apartment above her father's antique shop.
== Personality ==
He has a typical surfer personality (IE saying dude, gnarly, cowabunga, etc) and gets really ticked off when people call him by his real name instead of his mutant name. From what Ray Fillet has told him Mondo looks out for himself such as when Casey almost fell off a building and he laughed and didn't even bother to rescue him (despite the fact that he would've died or become hurt). However, 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.
== Abilities ==
Skateboard techniques: His skating skills are excellent. Due to his practice as a human and subsequent enhancement as a mutant, he is capable of travelling high speeds since.
Tail Balance : He can use his tail as an appendage as he uses it to hold his skateboard.
Enhanced Acrobatic: Mondo possesses a high degree of agility upon mutation.
Wall Crawling: Thanks to his mutation, Mondo is capable of climbing surfaces with ease, allowing his adhesive hands to support his own weight.
== Trivia ==
* He is voiced by Pauley Shore.
* In the 2012 series, Mondo Gecko wears a shirt that says "Tokay" on it. Mondo Gecko in this iteration is a mutant Tokay gecko, evident with blue skin with orange spots and no teeth.
