Onio

A comic character poking fun at the previous image of Saiyans as cool, good-looking people. Onio lands on Earth for his honeymoon, and decides to kill the human race to make Earth his country house (or country planet?). He bears much resemblance to Suppaman (Kuraaku Kenta) from one of Toriyama's previous manga, Dr. Slump. Onio is enraged, becoming a Super Saiyan when Neko Majin Z touches his wife's breasts, but quickly loses in a fight scene. (Wikipedia)
