Hun

Hun is the leader of the Purple Dragon Gang (as indicated by the purple dragon tattoo running up his left arm), and is often allied with The Shredder and his Foot Clan. After repeated encounters with the Teenage Mutant Ninja Turtles, Hun now hates turtles more than anything. Ironically, he was later transformed into a half-human/half-turtle mutant during an encounter with the Radical Reptiles and some mutagen from Dimension X.

In the IDW comic series, Hun is the former leader of the Purple Dragons, and is now the abusive father of Casey Jones, led to alcoholism by the death of his wife.
