Galactus is considered one of the three essential entities within the Marvel Universe alongside Eternity and Death and has been referred to as the "third force of the universe." Eternity and Death consider Galactus a peer and a sibling, with Death actually referring to Galactus on one occasion as "husband, father, brother, and son."
