When the Flash first debuted in 1940's Flash Comics #1, it wasn't <PERSON> who held the title of ``Fastest Man Alive.'' <PERSON> was the first hero to use the name. His costume is quite a bit different from the classic Flash suit, with blue pants and a silver helmet modeled after the Roman god Mercury. <PERSON> has stuck around even with heroes like <PERSON> and <PERSON> rising to prominence, and his costume has, too.
