Bio: Brother of Abyss, Ex Nihilo was born from a seed delivered by a Gardener (or Aleph) that was created by the ancient Builders. His original purpose was to aid suitable species in evolution. He was confronted by the Avengers after launching several origin bombs (devices that quickly accelerate evolution) at Earth. He also created the superhuman Nightmask who later joined the Avengers. He has since then promised to leave Earth alone using Mars as a base to continue his evolutionary development.
