Hun is one of the recurring characters and prominent villains from the Teenage Mutant Ninja Turtles franchise. He is the secondary antagonist in the 2003 animated series, and he is a large, hulking bully who is powerful, fast and quite skilled in martial arts. He is the leader of the Purple Dragons street gang in the 2003 Series and he is also The Utrom Shredder's right hand man. Although he despises all four Ninja Turtles, he has developed an intense rivalry with Casey Jones (as Hun, along with the Purple Dragons, are presumably the ones responsible for killing Casey's father).
