Oblivion is a cosmic abstract entity that represents the void of the universe. Oblivion, Infinity, Death and Eternity were formed by the First Firmament after the creation of this omniverse. These four cosmic beings view each other as siblings. Oblivion is in opposition to Infinity just as Death and Eternity are rivals in the universe. As a result, Oblivion and Death share a connection similar to that of Infinity and Eternity. These four cosmic beings represent the constant struggle of life and death within the universe. The realm of Oblivion is known as the Outer Void which is devoid of any matter or energy.,

Oblivion, being a fourth cosmos entity, is the eldest and most powerful of his three siblings.

Two of Oblivion's principle avatars are the Chaos King and Knull, who originated from the primordial Void before the universe began. While the Chaos King integrated into the Amatsu-Kami and became known as Amatsu-Mikaboshi, Knull created the symbiotes and other eldritch monsters from living darkness and waged war against the universe to return it to the Void.

Annihilus, lord of the Negative Zone, was allegedly the first born-born son of Oblivion. Oblivion also had a daughter, the being known as Mirage, who assumed the human form of Marge Smith. As Marge Smith, Mirage tried to turn Iceman against her father. In return, Oblivion used three aliens known as White Light, the Idiot and Kali to attack his daughter. He also tried to turn Iceman against Mirage, but in the end Iceman convinced the two to settle their differences peacefully.

In his rivalry with Infinity, Oblivion empowered Maelstrom as his avatar and sent him his agent, Deathurge to assist him. As Oblivion's agent, Maelstrom tried to destroy the whole universe, but he was stopped by Quasar, the avatar of Infinity. Oblivion, Infinity, Death, and Eternity then came to a new agreement.

Maelstrom returned to life later and came into conflict with the Great Lakes Avengers. During this conflict, Deathurge was sent repeatedly to collect the souls of Great Lakes Avengers who died. When he tried to claim the soul of Squirrel Girl's sidekick Monkey Joe, Mr. Immortal used the opportunity to grab Deathurge, now just the size and shape of a squirrel, and defeat him. The recently deceased Doormanencountered Oblivion, who made him his new agent, telling him that Deathurge had failed him. At Christmas, Deathurge tried to regain his position, but failed the test Oblivion gave him.

Oblivions true self

as Oblivions true self he is omnipotent, omnipresent, and nigh-omniscient in this state, he true self has annihilated a entire universe in an instant.

His true self resides in the outer void, an unending nothingness outside the omniverse. Reality would crumble if oblivion's true self departed from the outer void, for reality cannot sustain a force as powerful as oblivion's actual form.

Despite how strong oblivion is, even his true self is not as powerful as his grandfather, and he even fears the firmament. the first firmament was the 'first cosmos' but oblivion was only birthed in the fourth version of the multiverse.

Oblivion is said to be as strong as The Fulcrum and in his true form he could be even more powerful. Oblivion is known to be stronger than the likes of pre-recon beyonder and the living tribunal .
