Maruss (マルス, Marusu) and Rembrant (レンブラント, Renburanto) are a team who end up pursuing the team of Tia and Megumi early in the Mamodo fight. Their element is metal. Maruss was originally Tia's best friend in the Mamodo World, caring and looking out for her, compared to her bullying ways against Zatch. But once in the human world, his mentality changes, believing that friends can no longer be friends due to the nature of fighting and must go against one another to become king. Rembrant is a power-hungry, blithering idiot and a Middle aged dutchman who believes he can rule the world with his mamodo Maruss.
