Mariam has a wild spirit with an even wilder sense of humor. Her sarcasm often gets under Dungas skin and she rarely lets an opportunity to give him a jab slip by especially when hes fighting any battle. She is unpredictable and often leaves her opponents baffled from her unique moves. Her ability to confuse her opponents leaves them vulnerable for attack. She often teams up with her brother Joseph to take on their more difficult opponents. Together they are a formidable pair. Her bitbeast is Sharkrash. She was so absorbed in her destinyto seal the sacred bitbeaststhat she forgot about the beyblading spirit. Only after her battle with Max did she realize the true spirit of a Beyblader. source: wikipedia
