Oblivion

Part 1: The Dossier: An At-a-Glance Summary

1)
First appearance: Iceman #3 (1985) by J. M. DeMatteis and Alan Kupperberg.
2)
Oblivion is often referred to as a “he,” but as an abstract entity, it has no true gender. It chooses masculine forms or pronouns for the convenience of lesser beings it interacts with.
3)
The distinction between Oblivion and The Void (Sentry's nemesis) is a crucial piece of lore. Writers have been careful to keep these two concepts separate to avoid diluting the cosmic significance of Oblivion.
4)
In the Ultimates2 series by Al Ewing, the cosmic hierarchy was drastically redefined with the introduction of the Eighth Multiverse. The classic abstracts like Oblivion and Eternity were shown to be mere aspects of a far grander cosmic structure, fighting a “cosmic war of attrition” orchestrated by higher-order beings.
5)
The philosophy of Oblivion is rooted in the concept of entropy—the scientific principle that all ordered systems will inevitably move towards a state of disorder and decay. Oblivion is the metaphysical embodiment of this ultimate thermodynamic victory.
