Kus are enemies from The Legend of Zelda: A Link to the Past and The Legend of Zelda: A Link Between Worlds. They are the Dark World equivalent of River Zoras. These creatures live in the water, and attack by protruding their heads to shoot fireballs at Link. They have one eye, and are a grayish-red color. Kus only move underwater, but can still hurt Link if he swims into them. His only attacks must be done on dry land or shallow water, making it difficult to successfully defeat Kus. Long-range weapons are most effective; however, if Link is lucky, he can strike these creatures if they pop up out of the water close enough to where he is standing.
