The number of “universes” in the Marvel is extraordinary. From a quick glance apparently there’s at least 10,000. Check here if you would like to count. There are multiverses, megaverses, dimensions, realms, realities, and alternate-realities, all that is collected within an Omniverse. Also, the Omniverse apparently includes Marvel Comics, DC Comics, Image, Dark Horse, Archie, Harvey, Shueisha, Boom Studios, Rebellion, Dynamite, IDW, Graphic India, Derby Pop, Vertigo, Oni Press, Udon, Valiant, it even includes anime and manga not to mention our own world. Obviously, this is all made up, which doesn’t make the concept any less impressive.
According to the Official Handbook of the Marvel Universe Vol 4 17 the Omniverse includes “every single literary, television show, movie, urban legend, universe, realm, etc. ever . . . including fan-works. None of this is to be confused with the concept of “continuity.” Realities such as Earth-616 are considered a “single reality,” a continuity. For the record Earth-616 is the mainstream Marvel Universe. The reality of Earth-616 is that it has gone through ” eight different incarnations, all triggered by different instances of multiverse renewal, which constitutes in the destruction and re-creation of everything there is.” The beginning of the Earth-616 begins at the seventh incarnation that is marked by creation of Galactus.
While I found reading about the various Universes to be fun it’s time consuming. I certainly won’t recap it here. However, what is clear is the amount of love and effort that has been put into creating worlds, despite there extraordinary characters and stories manage to somehow feel real. If I had to choose ONE Universe it would simply be the Earth-616 because it’s the one that’s most familiar to me (by the way OUR Universe is Earth-1218). However, there are more Universes that I find interesting:
House of M (Earth-58163)
In the House of M, Magneto becomes leader of the world’s mutants. Mutants control the world and are racist towards humans. They control governments, businesses and culture. Humans like Spider-Man and Captain Marvel are the exceptions. This is all the result of the Scarlet Witch (Wanda Maximoff’s) reality warping abilities getting out of control. The X-Men and Avengers consider killing her, but Wanda changes the world be that can happen.
Amalgam Universe (Earth-9602)
This Universe is a parallel one that was a combination of Earth-616 and New Earth (DC). Two entities known as the brothers (each represent Marvel and DC) pit combatants from each universe against each other. The winner would destroy the other universe. To prevent this the Living Tribunal and the Spectre combine the universes together resulting in heroes that combined together like, Doctor Strangefate. He’s was a combination of Doctor Fate, Doctor Strange and Professor X.
The Wastelands (Earth-807128)
In this reality the villains united fifty years prior to Old Man Logan. America is divided up by them an renamed Amerika. Logan kills The Red Skull, many heroes died fighting Galactus, who became a power source. Hulk impregnates She-Hulk and they have inbred children. Most of this universe is the same as Earth-616, except Logan is much older than he is in Earth-616.
