Korin (or Karin) is a fictional character in the Dragon Ball/Dragon Ball Z manga and anime series. In the early Harmony Gold English Dragon Ball dub from the 1980's, he is known as Whiskers The Wonder Cat.
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. 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.
