Starting out as a recurring villain, Robin Mask soon became one of the most essential members of the Seigi Choujin (Justice Supermen) team. Robin wore knight-type armor made out of sapphire (later remade out of steel), and wearing the armor reduced his strength, giving his opponent a fair chance at beating him. Although Robin is only a few years older than most of the cast he is considered the veteran of the group and often comes up with the teams' overall battle plan.<br /> In the anime he is depicted as wearing a blue undershirt underneath his armor, making it seem at times that he has blue skin.<br /> <br /> (Source: Wikipedia)<br /><br />
