Korin is an ancient, wise, and immortal cat-like deity who resides atop the towering Korin Tower, a structure positioned below the lookout of the Earth's guardian Kami. Having lived for over eight hundred years, he is a highly revered martial arts master and the sole cultivator of the legendary Senzu Beans, mystical legumes that can instantly heal any injury and restore a person's entire energy. In the film Dragon Ball Z: Cooler's Revenge, Korin appears in a brief but crucial supporting role. His personality remains consistent with his general depiction, being calm, pragmatic, and possessing a subtle, mischievous streak, though he ultimately acts with the best interests of Earth and its defenders in mind. When the hero Goku is severely injured by the invading antagonist Cooler, Goku's young son Gohan travels to Korin Tower seeking help. Motivated by the necessity of restoring a warrior capable of meeting such a powerful threat, Korin provides Gohan with a supply of Senzu Beans. This act is the catalyst that allows Goku to make a full recovery and confront Cooler in the climactic battle of the film. Within the story of Cooler's Revenge, Korin's key relationships are with Gohan, whom he aids directly, and his long-time associate Yajirobe, who lives with him on the tower. The film does not depict any significant personal development for Korin, as his appearance is limited to this pivotal resource-providing function. His most notable abilities, referenced through the context of his role, are the cultivation of the Senzu Beans and the high-level martial arts expertise he has refined over centuries.
