Bio: Infinity is one of the four main abstracts within the Marvel Universe alongside Eternity, Death, and Oblivion. While these beings regard each other as siblings, they are not family in any conventional sense. Infinity is the personification of space, and together with Eternity they represent all life and existence in the universe - while their counterparts Death and Oblivion represent death and non-existence.
Infinity is rarely seen by humanoid beings. The entity was first glimpsed by the Asgardian gods Odin and Thor, and is not seen again until it - together with Eternity and the other cosmic beings - battle the Titan Thanos when he has possession of the Infinity Gems. The concept Oblivion later tries to destroy Infinity with an avatar, the being Maelstrom. Infinity responds by empowering the hero Quasar, who defeats Maelstrom and ends the feud.
