Radiation Roy is Roy Travich, a 30th Century super-villain and enemy to the Legion of Super-Heroes. He originally tried out for membership in the Legion, but was rejected because he could not properly control the radiation emitting from his body. He would later become a member of the Legion of Super-Villains and the xenophobic Justice League of Earth. Reboot Legion continuity introduced a new Roy Travich who became a member of Workforce as the super-hero Radion. Radiation Roy was created by Jerry Siegel, Otto Binder, John Forte, and Sheldon Moldoff, first appearing in Adventure Comics #320. (1964)
