Legion of Substitute Heroes

"Many young people have tried unsuccessfully to join the Legion of Super-Heroes, for it is no easy matter to be admitted to the mightiest crime-fighting group in the 30th century. But Brek Bannin, known as Polar Boy, was one reject who would not accept defeat. Contacting four other worthy applicants who, upon being turned down, had been given anti-gravity belts as 'consolation prizes', he formed with them the Legion of Substitute Heroes, a group ready to take over whenever an emergency arose which the Super-Heroes could not handle." (Adv No. 323, Aug 1964: "Origin of the Legion of Substitute Heroes!")

The Legion of Substitute Heroes consist of Polar Boy, Night Girl, Chlorophyll Kid, Fire Lad, Stone Boy, and Color Kid.
