South Kaio

South Kai (Minami no Kaiou; lit. "South Kaio" or "South King of the Worlds") is the ruler of the South Galaxy. He is tall, has light pink skin, and wears white Jackie Ohh sunglasses.

South Kai trains his fighters in a defensive manner. Fighters of his quadrant include Caterpy, Froug, and Torbie. His newest fighter is Papoi, whom he quickly understands to be weaker than Goku. Out of the fighters of his quadrant, Froug was able to reach the quarter finals of the Other World Tournament, and Torbie managed to reach the semi finals before being eliminated by Pikkon.

East Kai and himself do not mind North Kai and West Kai's rivalry, and almost seem to enjoy it. He, like the East and West Kais, makes fun of how North Kai is dead and cheers about it too.

He has the ability to alter the weight on training weights, as is seen when King Kai instructs him to increase Goku's training weights to ten tons each. South Kai then shoots out a wave, crying out the new weight, as the weights are adjusted. He seems confident that Goku will not be able to lift the far heavier load, but gets baffled when Goku turns Super Saiyan and starts to train with ease. He quickly leaves the scene with Papoi.
