Hun is a character of the Teenage Mutant Ninja Turtles. He is the leader of the Purple Dragons, a henchman of Shredder, enemy of the Ninja Turtles, and Casey Jones' archenemy.
Hun first appeared in "Casey Jones vs the Underworld", introducing himself to Jones as the new leader of the (just defeated) Purple Dragons during a bank robbery. Hun then easily defeats Casey and made off with the money, along with his cohorts. Hun later appeared delivering chemicals to Shredder, who complimented his success, martial arts mastery, and leadership skills. Hun then offered to show Shredder around the Alumond Chemicals factory, as it made the chemicals needed for his mind control formula and was on Purple Dragon territory. His tour was interrupted by Casey Jones, who began to fight him for a second time after the turtles showed up. He was defeated when Casey Jones pushed him off a balcony into a vat of chemicals.
Hun appeared again in "Meet Mondo Gecko", fighting Casey, Michelangelo and Mondo Gecko, only to be defeated again with Mikey and Casey having to stop Mondo from stealing his wallet. Later, Hun appeared in the audience of Fishface's underground race, alongside the rest of Shredder's henchmen, certain mutant villains, and top underworld figures. He later leaves the race in disappointment after Mikey, Casey, and Mondo barely win the race and the other Turtles show up.
In "Broken Foot", Shredder hires Hun and the Purple Dragons to guard his money stocks from Karai and Shiniagami. Hun and the Dragons are surprisingly able to beat them in combat, however, they are ultimately defeated when Leonardo joins the fight. Beforehand, Hun shows how loyal he is to the Shredder, outright calling Karai a "spoiled little girl" for her attempts at revenge.
In "Bat in the Belfry", Hun briefly appears with the Dragons being easily defeated by Casey Jones, Michelangelo (dressed as Turflydle), Wingnut and Screwloose.
In "The Power Inside Her", Hun and the Purple Dragons are about to mug a helpless old lady unless she pays for protection. At this moment, a wild April appears and defeats Fong and Tsoi. Hun offers her to join the Purple Dragons, but she refuses and sends him flying, crashing into a parked car. This becomes his last appearance in the series as he does not even appear during the final battle with the Turtles and Shredder.
