Silverman  

Mûsman, Perfect Second, シルバーマン

The brother of Goldman, Silverman's spirit resided within the Silver Mask. He was granted permission to lead a group of choujin known as the Seigi Choujin by The Man. However, he was eventually manipulated into fighting against his brother, Goldman, by Justiceman. In their brutal fight, they both became the Silver Mask and Golden Mask respectively, which were kept safe on Planet Kinniku. Despite being brothers, Silverman and Goldman would frequently quarrel with each other and ultimately end up killing each other in combat. Their feud was later reignited during the Golden Mask arc.
