its strength and create armies of Anti-bodies it plans to send throughout the universe to conquer worlds. This behavior attracted the attention of the Rigellian Colonizers, who feared that the nearby Ego would consume their homeworld. They asked the help of the Thunder God, Thor, to defeat Ego. Accompanied by a Rigellian Recorder, Thor encountered Ego, fought his Anti-bodies, and stunned him with a powerful storm. Feeling humiliated by his defeat, Ego vowed never to leave the Black Galaxy. Several months later, a weakened Galactus invaded Ego's space and sought to replenish his energy by consuming Ego. Thor aided Ego in battling Galactus and drove Galactus off. In gratitude, Ego allowed its surface to become the new home of the Wanderers; a group of various alien races whose planets had been the very first to be devoured by Galactus billions of years ago. 1970s The Rigellian Tana Nile took a sample of Ego's form, in the hope that this could be used to fertilize sterile worlds being considered for habitation. However, this act drives Ego insane, and it soon gives in to its primordial urges and absorbs the Wanderers, which causes Thor to side with a returning Galactus.

Unable to locate him, Ego attacks Earth. He causes massive destruction, which is later undone by a reality-altering mutant. The Fantastic Four attempted to defeat Ego by removing the power cell from one of the attached propulsion engines, which the Thing attempts to throw into Ego's "brain". In response, an angered Ego attempts to counter with his remaining engines but, with one engine now deactivated, the other propels the now-out-of-control planet into the Sun, its gravitational pull breaking apart Ego's substance. Ego, however, slowly reforms from a few surviving particles and repairs the propulsion unit. Ego then digests a number of Dire Wraiths to replenish its energy reserves, and battles the Spaceknight Rom. Ego later joins the Elders of the Universe in a plan to destroy Galactus. Ego is sidelined before the confrontation when he is defeated by the
