S-1 was the chief of the Suprematons, who was given advanced programming that enabled him to develop emotions. After Supreme left Earth in the 1970s, a lonely S-1 gradually went insane, constructing several Suprematons duplicates of Supreme's friends and family to keep him company in the Citadel Supreme. When Supreme finally returned, S-1 attacked him, forcing the hero to destroy him.
Supreme rebuilt S-1 with a more stable personality, and he once again became the leader of the Suprematons. However, after Judy Jordan was transferred to a Suprematon body, S-1 fell in love with her. The two married, and S-1 took the new name Talos; the pair settled on an unhabited world which they named Suprematonia.
