While Kung Fu Man was walking with his girlfriend, Suave Dude attacked them with his minions. He kidnapped Kung Fu Man's girlfriend while Kung Fu Man was fighting the minions and fled for his mountain temple hideout. Kung Fu Man was determined to rescue his girlfriend, so he gave chase to Suave Dude. Once in the temple, he fought an evil clone of himself. After defeating the clone, Kung Fu Man searched for Suave Dude and his girlfriend. However, because they haven't made the Suave Dude character yet, Kung Fu Man was unable to find them.
