Abraxas

Abraxas presumably came into existence when the original universe that eventually branched out into the multiverse was formed, spontaneously assuming the embodiment of destruction that was the counterpart to the very act of creation embodied by the being known as Eternity. Abraxas grew within the core of Eternity, although into each reality Eternity made certain a being existed to keep Abraxas from emerging. This being would later be known as the planet-devouring Galactus
