History
Ego is a celestial creature who believes his true purpose is to complete the task he calls "The Reach", which involves spreading his celestial powers throughout the universe, eradicating all other life forms.[1]
Ego was seen floating in space as Galactus made his way towards Earth.[2] He was later pulled into Chronopolis on accident by the Avengers, but was eventually put back.[1]
At some later off-screen time, Ego fought the Guardians of the Galaxy.[1]Attributes
