Korin

Korin is the 800 year old white cat who lives at the top of Korin Tower. He is a deity just below the rank of Kami. He plays a large role in Dragon Ball when he trains Goku ,(although Goku doesn't know it at the time). He also gives Goku the Super God Water which gives him the power to defeat King Piccolo. In addition to that, Korin is the only one who grows the Senzu Beans which heal wounds and are equivalent to eating 10 days worth of food. In DBZ he shows up from time to time, but not too often. Yajirobe ends up living with him in the tower.
