Fan CastingFlash: Ultimate Speedster

Jason Peter Garrick is a college student, who accidentally inhaled hard water vapors after taking a smoke break in his laboratory where he had been working. As a result, he finds that he can run at superhuman speed and has similarly fast reflexes. Retcons imply that the inhalation simply activated a latent metagene. After a brief career as a college football star, he dons a red shirt with a lightning bolt and a stylized metal helmet with wings battling the Faultless Four, a group of blackmailers (Sieur Satan, Serge Orloff, Duriel, and Smythe), who plot to steal an atomic bombarder and sell it. It is later revealed that a professor named Edward Clariss found the last container of heavy water vapor and used it to gain super-speed, becoming the Rival. He briefly takes away Jay's speed after capturing him, making him super slow, but Jay uses the gases again, allowing him to regain his super speed and defeat the Rival.
