Yuck

Yuck is an evil Level 5 Woo Foo Warrior and a recurring enemy in the TV series Yin Yang Yo! This entity was formed from Yin's obsession with control and Yang's aggression. As a repulsive, bad-tempered mutant rabbit, Yuck wants nothing more than to become the most powerful Woo Foo Knight ever. The one way he can accomplish this is by eliminating Master Yo and his creators, Yin and Yang. Despite being half female, Yuck is predominantly sports male gender characteristics and lacks eyelashes, much like Yin and Yang's combined Aura.
