King Kai is a deity and martial arts master. He oversees the north quadrant of the Universe and his planet is found at the end of Snake Way.
He has trained many disciples such as Goku, Piccolo, Tien, Chiaotzu and Yamcha. He lives with his monkey Bubbles and friend Gregory. He enjoys driving his car and telling jokes (most which are very corny and unfunny).
Despite his foolish nature he is also very wise and knowledgeable. He specializes in telepathic communication and also taught Goku the Spirit Bomb and Kaio-ken.
