Hun is a fictional character from Teenage Mutant Ninja Turtles first introduced in the 2003 animated series. He is the leader of a New York City street gang called the Purple Dragons whose base of operations is located in the Lower East Side of Manhattan. He is an on-and-off ally and enemy of the Shredder, an antagonist of the Ninja Turtles, and is also the archnemesis of Casey Jones. Hun has been with the Purple Dragons long before the Shredder came to New York and established an American branch of the Foot Clan. He has led the gang's criminal dealings primarily in racketeering, robberies, and arms trafficking throughout the city before turning the Purple Dragons from a mere street gang into a criminal syndicate.
