Masato Kazami is a villainous character that appears in Bakugan Battle Planet who owns Aquos Serpenteze. He is the cousin of Shun Kazami.

Masato Kazami is Shun’s older cousin. He has been brought in by AAAnimus Inc. (and secretly by Shun’s father) to knock Shun out of the Awesome Ones. Masato wants to prove his worth by either bringing Shun back into the family fold or forever exiling him like his family. Masato is cunning, mean and heartless.
