Ego (What if?)

Ego is a Celestial being who achieved self-consciousness and in search of meaning for his existence, decided to transform all life into extensions of himself. Given that his power would not be enough for this task, he started to sire children until one of them became an heir of his own powers, and thus able to help him. He eventually fathered the young Peter Quill, who inherited his powers, and together they travelled to his home planet, Earth, to finally start the Expansion.
