The Foot Clan itself is under the ultimate command of The Utrom Shredder Ch'rell, and his second in command is his adopted daughter Karai. Prior to Karai's appearance, Hun served as Shredder's second and chief enforcer as well as leading the Purple Dragons. But when Karai appeared, she was quickly shown to be higher in Shredder's favor than Hun. After The Shredder was exiled to the ice asteroid belt of Mor Tal in the episode "Exodus, Part 2", Karai assumed command of the Clan and the mantle of the Shredder giving the Foot Ninja and Foot Elite new designs while Hun evolved the Purple Dragons from a street gang to an organized criminal organization.
