Oblivion is a fictional character, in the Marvel Comics universe. His first appearance was in Iceman #3 and he was created by J. M. DeMatteis and Alan Kupperberg. Oblivion is a cosmic entity and another aspect of Death, a personification of death. Oblivion represents non-existence and is a counterforce to the expanding universe.
Oblivion has a daughter, the being known as Mirage, who assumed the human form of Marge Smith. As Marge Smith, Mirage tried to turn Robert Drake, the superhero 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 Doorman encountered 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.
