The Progenitor was a Celestial who was infected by the Horde and died on the newly formed planet Earth. This event is said to be the origin of life on Earth and the reason for why so many of Earth's inhabitants have superpowers.

It was later used to manufacture a new Celestial to end a conflict between the Eternals and mutants. H
