Oblivion is a cosmic abstract entity and another aspect of Death, a personification of death. Oblivion represents non-existence and is a counter force to the expanding universe. Oblivion came into existence together with the cosmic entities Eternity, Infinity and Death when the universe was created and these beings see each other as siblings. Another being, known as Galactus was born later, from the ashes of the previous universe and is also seen as a sibling by these beings. Oblivion has a very close relationship with Death and the two may be different aspects of the same being, just as Infinity and Eternity are. Just like Eternity and Death have a strong rivalry, Oblivion has a strong rivalry with Infinity, a rivalry usually fought through avatars.
