Demeityr was friends with Pamela Douglas while she was living on Titan, waiting the rebirth of her cousin Moondragon in a new cloned body. Pamela was attracted to him, but Moondragon found him lacking in intelligence. When Moondragon was finally reborn, she and Pamela chose to depart Titan. Demeityr tried to convince Pamela to stay, offering to find a surrogate to help care for Moondragon in her infant form, but Pamela was determined to leave.
Later, Pamela encountered members of the Dance race, and accessed her own innate superhuman powers. She somehow caused Demeityr to be teleported to her, and he joined her in her adventures.
Demeityr journeyed with the others to visit Moondragon's friend Cloud, but the reunion ended badly when Moondragon flew into a fit of rage over her still-young body. Demeityr left to join Pamela in her quarters, but they were interrupted by a psychic attack from Moondragon. Moondragon created an illusionary form of her old body, and attempted to seduce Demeityr, but he was too frightened by her to love her. Pamela and Demeityr tried to fight Moondragon, but she overcame both of them, and cast them into space. They were rescued by Cloud, just as Pamela's powers fully surfaced, transforming her into Sundragon. They forgave Moondragon for her actions and then set off into space.
