The Omniverse is the collection of every single universe, multiverse, megaverse, dimension (alternate or pocket) and realm. This includes not only Marvel Comics, but also DC Comics, Image, Dark Horse, Archie, Harvey, Shueisha, Boom Studios, Rebellion, Dynamite, IDW, Graphic India, Derby Pop, Vertigo, Oni Press, Udon, Valiant, and every universe ever mentioned or seen (and an infinite amount never mentioned or seen) including our own world. Everything is in the Omniverse, and there is only one Omniverse. According to the Official Handbook of the Marvel Universe: Alternate Universes, "It includes every single literary, television show, movie, urban legend, universe, realm, etc. ever. It includes everyone from Popeye to Rocky Balboa to Ronald Reagan to Romeo and Juliet to Luke Skywalker to Snoopy to Jay and Silent Bob, etc." This includes universes outside of American and European western comics, such as Dragon Ball, Naruto, Bleach, One Piece, Ghost in the Shell and etc. eastern comic book media. The Omniverse is EVERY reality, including those published by all other companies. Even fan-fictions, cancelled works, mere fantasies, wishes of thoughts created by people, future comic book publishing companies and fictional universes yet to be published are considered part of the Omniverse; simply put, the Omniverse is every version of reality and existence imaginable and unimaginable.

The classification system for alternate realities was devised, in part, by Mark Gruenwald.


A Universe/continuity is a single reality, such as Earth-616, the mainstream Marvel Universe/Continuity. In Marvel Comics, the concept of a continuity is not the same as "dimension" or "galaxy"; for example, characters like Mephisto and Dormammu hail from alternate dimensions and the Celestials from another galaxy, but they all nevertheless belong to Universe-616. A continuity should also not be confused with an imprint; for example, while the titles of some imprints, such as Ultimate Marvel, take place in a different continuity, some or all publications in other imprints, such as Epic Comics, MAX, and Marvel UK, take place within the Earth-616 continuity. Note that in context the Marvel Universe is sometimes used to refer to the Marvel Multiverse, and sometimes used to refer to the Earth-616 continuity.


A Multiverse is a collection of alternate universes, with a similar nature and a universal hierarchy. The Marvel multiverse contains Earth-616 and most of the What If? universes, as well as the vast number of alternate Marvel Universe Earths.

The original term and concept were coined by Michael Moorcock for his "Eternal Champion" sequence. The lead characters from Moorcock's work are obviously the inspiration for the Captain Britain Corps.


The Megaverse is a structure present between Multiverse and Omniverse which links realities more closely associated to the mainstream Multiverse, and more distant realities, such as the Shadowline.[1]

There are certain universes outside of the Marvel multiverse that are collected inside their own multiverses, which then form groups of multiverses.[citation needed] The 21st century edition of the Official Handbook of the Marvel Universe posits the term Megaverse (although Marvel does not actually endorse the use of this term because of trademark issues) as the name for this larger grouping; because there is always the chance that some future publications will increase the interactions between different Multiverses, this is a fluid definition.

  • According to the Merriam-Webster Dictionary, an Omniverse is simply "a universe that is spatiotemporally four-dimensional".[2]
  • Kevin Brashear, son of the Blue Marvel, is noted as being the first human being to exit and later re-enter the Omniverse in Captain America and the Mighty Avengers #7. How that could even be possible as the Omniverse has been described as encompassing everything imaginable has not been explained.
