A mysterious lion-like humanoid alien who fights with Plasma Claws and another member of The Four Saint Beasts with the same mission as Byakko. Rai-on is more aggressive by nature compared to Byakko and is a wrathful ninja. Rai-on's ending is similar to Byakko's, with him defeating Bilstein first is then forced to battle against Byakko. Even though Byakko manages to escape, Rai-on sends the other Saint Beasts to hunt the wounded ninja down and anticipates another bout between himself and his former teammate.
