During the initial attack of the Black Cross Army against the Japanese EAGLE bases, Bronze Mask attacked the Kyushu branch, killing everyone with Daita Ooiwa the only survivor of the attack.
Bronze Mask wears nothing but bronze armor. He bribed Daita with a bowl of curry rice in an attempt to regain an object the Gorengers stole from a Black Cross Army base. He tricked Daita, threatening to blow up a child inside a pressure sealed bomb. The staff shoots sparks that travel long distances. For some reason the dart blower also doubles as a flute which Bronze Mask uses to announce his presence. He was destroyed by Gorenger Storm attack, which pierced his bell armor in mid-air.
