As befitting the avatar of an entity of destruction, Rahu is the most powerful robo in Custom Robo (GameCube). Each of its forms are unlocked in the second story campaign, "The Grand Battle". It has three forms: Rahu I, Rahu II, and Rahu III, with its final form having the highest stats of any robo in the game. Its body, gun, and pod change as it evolves, but the bomb and leg remain the same.
