Sarmon Vidar who later became Universo was a member of the Green-Lantern Corps in the 30th Century. He had been a Green Lantern for only a short time when the Guardians of the Universe assigned him to Earth to stop the specific experiments that could reveal the origin of the universe. However, Vidar became tantalized by the possibilities that learning the origin of the universe itself would make him more powerful than the Guardians and sought to obtained it. Ultimately, the rogue Green Lantern's plot was foiled by the Legion of Super-Heroes, who they then turned over Vidar to the Guardians whom they stripped of him of his power ring; in which it would later passed on to his righteous son Rond Vidar.
