During John Byrne's run in the 1980s, Doom attempted to steal the cosmic powers of Terrax the Tamer, but Doom's body was destroyed in the resulting fight between Terrax and the Silver Surfer. Doom survived by transferring his consciousness to another human, and is returned to his original body by the Beyonder (who had reached into the relative future to 'recruit' Doom for the conflict on Battleworld that the FF had participated in a few months ago from their perspective). While on Battleworld, Doom attempted and briefly succeeded in stealing the Beyonder's power, but it proves too vast for him to control and the disembodied Beyonder is able to take his power back.
