Page "Ego the Living Planet" Paragraph 10

Ego began absorbing space vessels and even other worlds to survive, planning interstellar conquest.

This behavior attracts the attention of the Rigellian Colonizers, who fear that the nearby Ego will consume their home-world.

They recruit the Thunder God Thor to defeat Ego.

Accompanied by a Rigellian Recorder, Thor encounters Ego, who vows to never leave the Black Galaxy and renounced its plans of conquest, feeling humiliated by his defeat.

Several months later, a weakened Galactus invades Ego's space and seeks to replenish his energy by consuming Ego.

Thor aids Ego in battling Galactus, and drives Galactus off.

In gratitude Ego allows its surface to become the new home of the Wanderers, a race whose planet had been the very first to be devoured by Galactus billions of years ago.
