List of Alternate Universes and Dimensions


The number of alternate universes within our Multiverse is theoretically infinite, but traveling between those universes is extraordinarily difficult even with the most advanced and sophisticated technology. Thus our knowledge of such universes has so far been limited to a few hundred of them, and there are really only a handful with which we have had repeated or sustained contact. Alternate universes can be separated into several different categories, as follows:

Mundane universes are those that most resemble our own: conventional, spatial dimensions governed by a system of natural laws and scientific principles. The universes that most resemble our own are known as “parallel universes.” These share not just a passing resemblance to our own universe, but are in fact exact one-for-one duplications, at least up to a point. At some point in their histories, usually called the “point of divergence” (POD), a parallel universe may deviate from ours and begin to follow a different path, with its own unique history. However, the laws of nature remain the same.

Note also that in some of the parallel universes, time passes just an imperceptible fraction faster or slower than it does in our own, original universe. Because the multiverse is billions of years old, however, even a fraction of a second difference per year could mean that that the relative timelines of the parallel universes currently differ by hundreds of years. Where this difference is know, I have noted it below.

Dr. Reed Richards, perhaps the world’s foremost expert on parallel universes, developed a complex, three-tiered numerical coding system for cataloging any and all possible parallel universe experiences. From this catalog, his Future Foundation identified a small number of parallel universes that have had the most cross-over with our own and can thus be confirmed with the highest degree of accuracy. These they identified with very simple, codes for easy identification. The most significant parallel universes identified thus far by the Future Foundation are listed below.

The Primary Universe

This is the universe we live in (also known as the “Earth-Prime” universe). You can find a detailed history for it here.


The Earth-A universe is essentially the Earth-A alternate universe of Marvel Comics, where, among other changes, Reed Richards of the Fantastic Four became The Thing while Ben Grimm became Mr. Fantastic.


The Earth-Ace universe is the universe of Strikeforce: Morituri. Its timeline is approximately 87 years ahead of our own, and diverged in 2069 (1982 in our universe) when an alien species known as the Va-Shaak (or “The Horde”) invaded Earth. In 2072 (1985 in our universe), Dr. Kimmo Tuolema perfected the “Morituri Process,” which allowed people with a specific type of genetic structure to have a new metabolism overlaid on top of their original one, granting them enhanced physical attributes. The Morituri Process bestowed unique superhuman powers that could be used to fight the Horde. However, it also proved 100% fatal, burning out the host human in approximately one year.

The Earth-Bravo universe is an alternate universe where time is approximately 2,037 years ahead of our own universe. In the early 21st century, technological advances led to conditioning of humanity that reduced crime and increased “human satisfaction.” (This peace was briefly interrupted in 2032 when the 20th century criminal Simon Phoenix escaped from his cryogenic prison.) By the 26th century, all of Earth had been united into a single World State, which had crafted a “brave new world” based on consumerism and the loss of individuality. Over the next few centuries, however, there was a backlash against the “mind control” of the World State and its rigid caste system and arbitrary limitations. By the 40th century (the 20th century in our universe), the human population had exploded into the hundreds of billions as multi-tiered, continent-sized cities covered the face of the planet and robot servants performed all of the labor. It was around this time that Kang the Conqueror arrived. A native of Earth-M, Kang corrupted the formerly benevolent robots of Earth-Bravo and turned them into oppressors instead of servants. There were pockets of resistance, including a human named Magnus who had been raised by robots in North-Am (the city covering the entire continent of North America) to fight evil robots. However, the vast resources of Earth-Bravo were soon almost exclusively under Kang’s control. Although Kang was often absent for long stretches, the robots held it for him, and he would use Earth-Bravo as his headquarters to invade other universes – including our own.

Earth-1 through Earth-12

At least eleven alternate universes were known to have perished during the Crisis on Infinite Earths event in 1985. Originally, it was believed to have been 12, but Earth-11 (a universe in which many prominent heroes and historical figures of Earth has reverse gender) was later discovered to have survived. Not much is known about them. Several other universes that were attacked by the Anti-Monitor survived and are better understood, including Earth-G, Earth-M, Earth-X and our own universe.

Theoretically, non-parallel universes are almost infinitely more plentiful than parallel ones. However, in most cases they are also more alien in nature and more “distant” and difficult to identify and travel to. Non-parallel universes have no Earth analogs, nor analogs of any other features of our universe. And while they are governed by laws of nature, those laws may be quite different than what we are used to. Time may flow at a different rate, matter and energy may behave differently, magical forces may be more readily accessible, and so on.

The Beyond

The Beyond is a strange, unknowable dimension that is home to the near-omnipotent alien species known as the Beyonders.

The Dark Dimension of Dormammu

The Dark Dimension is a vast universe ruled by Dormammu. Thanks to its Dark Lord’s powers, it has absorbed many other universes and realms over the years, and Dormammu’s ultimate goal is to conquer and absorb the entire Multiverse.

Eä is a transcendent universe, a “higher plane” whose nature lies far beyond the understanding of ordinary mortals. The entire universe was created by Eru Ilúvatar and the Ainur around 500,000 BCE. Structurally, it is divided into three zones: the Celestial Sea, the Underworld and the Abyss.

The vast, Celestial Sea resembles outer space in our universe except that it is not a vacuum: the celestial aether insulates travelers against temperature variations, and allows air in the vicinity to cling to travelers like a bubble, making space travel possible without protective gear. Eä’s Celestial Sea is populated by various planetoids, many the size of continents. Many of these planetoid “realms” are connected to Earth by Yggdrasil, the World Tree, and are where the “gods” of Earth make their home, including AmaAsgardCelestial DilmunCelestial HawaikiCelestial HeliopolisCelestial KalevalaHanan PachaIfeJotunheim (home of the former giants of Earth), NirvanaOlympusOmeyocanShipoloSvargaSvartalfheim (home of the dark elvesand Ta-Lo.

An unfathomable distance beneath the Celestial sea lies the Underworld, realm of the dead, a place for those souls who are ready for some kind of Afterlife. (It is not the final Afterlife, however. Souls who move on to the final Afterlife leave our Multiverse forever.) It takes the form of a limitless plain, featureless and gray, with immeasurable miles separating each of its many realms. The Underworld is connected to Earth and the Celestial Sea via Yggdrasil, the World Tree. However, the souls that are kept there are very well guarded and not easily retrieved. The many realms with connections to Earth include: AnnwnDuatHadesHel (which includes Niflheim, the icy realm of the dishonored dead, and Valhalla, the abode of the honored dead, which is directly connected to Asgard), IkuThe Nine Hells (vast, concentric pits), PoPurgatorySeanaTuoniUku PachaXibalba and Yomi. It is often confused with The Abyss (see below), but not all of it is bleak and desolate. Indeed, there are many gods who choose to live there rather than in the Celestial Sea above.

Far beneath the plain of the Underworld lies the Abyss, a vast, bleak universe that is home to monsters and demons. It is formed of an impenetrable, dark stone-like substance surrounding air-filled pockets, some as small as a single room and some millions of miles across. It has known connections to Earth and the other realms via Yggdrasil, the World Tree, although such connections are carefully guarded. Because of its nature, the Abyss has often been used as a realm of imprisonment or punishment. For example, the Titans were imprisoned in one of its realms, called Tartarus, by the Olympian gods. Other Abyssan realms include Muspelheim (home of the fire demons), Other-Realm (the domain of Chthon) and The Serpent’s Sea (the realm of Set). Unlike the similar Tunnelverse (see below), gravity works in only one direction in The Abyss, so there is a consistent downward direction.


Limbo is a dark and mysterious universe where the forces of magic are particularly evident, and the laws of nature are unpredictable. It was known as “Darkworld” to the ancient Atlanteans, and is also known to some by the name “Otherworld.” It is populated by planetoids floating through space without stars (although many of the planets and planetoids have their own sources of illumination). Among the known realms in this universe are Avalon (home of the Captain Britain Corps), Fomor (home of the Fomorians), GemworldOtherplace (the domain of the demon Belasco), the Under-Realms of the demon Trigon, and Zrfff (a.k.a. “The Fifth Dimension,” home to a species of mischievous imps).

The Microverse

The Microverse is an alternate universe that can be reached from our universe by compressing one’s own mass to a certain point, thereby forcing it through an artificially created nexus into the other universe. The Microverse is a completely independent universe, without an Earth analog, and has different laws of nature. It is held together by the Enigma Force and is home to a large number of alien races, most of them uncataloged, including the Acroyears of Spartak and the Insectivorids of Kaliklak. In recent times, much of the Microverse was conquered by the despot Baron Karza, sworn enemy of the Micronauts. Other regions of the Microverse include Sub-Atomica, the realm of the Psycho-Man, and Tok, which is home to the Lizard Men of Tok.


Home of the planets Eternia and Etheria, among others.

The Negative Zone

The Negative Zone is an antimatter universe. It is a much older universe than our own, and the rate of time passes more quickly there.

The Smoke Dimension

Not much is known about the Smoke Dimension beyond the fact that it was the home of Aarkus, an extradimensional police officer who was briefly trapped on Earth in the 1940s.

The Sornaii Dimension

A relatively small universe, the Sornaii Dimension contains 15 worlds: seven worlds of light, seven of darkness and Pytharia, which hangs in the balance.

The Tunnelverse

The Tunnelverse is a universe where “outer space” is composed of solid earth and the “planets” are large openings within that solid matter. With hundreds to billions of miles of rock separating them, travel between planets is extremely difficult and can usually be accomplished only with the aid of extradimensional portals. Gravity works differently in the Tunnelverse, so that it pulls uniformly toward the inner surface of the tunnels. (This creates a point of zero gravity in the exact center of each opening.) There are two well-known planets in the Tunnelverse: Tunnelworld, a cylindrical world, and Hollow Earth, a spherical one. Because there are many portals to it buried far beneath our own planet’s surface, Hollow Earth is often mistaken for being within the Earth itself. (There is also one portal to Hollow Earth from the surface of Earth, located near the North Pole.) Hollow Earth goes by many names, including “Pellucidar” and “Skartaris.” It is populated by creatures from Earth’s Subterranea (including dinosaurs) as well as creatures native to the Tunnelverse.

Pocket universes are small but lasting universes, distinct from but usually connected to one or more larger universes. They have their own relative space and energy, meaning that they are not merely temporary manipulations of extra-spatial dimensions.


Azarath is a small planetoid in a mystical pocket universe. It was once a paradise with a temple that guarded a great door leading to the realm of the demon Trigon in Limbo. In 1984, Trigon finally managed to invade and destroy the Azarath, and it now lies in ruins and uninhabited.

The Counter-Earth Universe

The Counter-Earth universe is a vast, artificial realm createrd by the mysterious, extradimensional Beyonders as a sort of “museum” for planets and other relics from througfhout the Multiverse. It is named after the artificial planet Counter-Earth, which they took from our universe in 1980. It is also the home of various “Battleworlds,” which they create for their own entertainment. See the complete Counter-Earth universe timeline here.

The Crossroads

The Crossroads is a magical nexus point to an infinite number of alien dimensions. It has appeared in different forms to different travelers, sometimes with a sign post guiding explorers to different destinations.

Fourth World

Fourth World is a massive pocket dimension containing the sister planets of Apokolips and New Genesis. These formed from the remains of Godworld, a planet formerly of our own universe, which was cast into a space “between dimensions” many eons ago, leaving it accessible only by means of “Boom Tubes.”

The Mojoverse

The Mojoverse is home to a species known as the Spineless Ones. They created a race of humanoid slaves, one of whom became the freedom fighter known as Longshot, who would eventually cross into our universe.

The Seven Capital Cities of Heaven

The Seven Capital Cities of Heaven each exist in pocket dimensions that intersects with each other and with Earth. Each of them is represented by a champion known as an “Immortal Weapon,” and these champions must compete in a tournament every 88 years to determine the order that the cities will appear on Earth. They may also be reached by magic. The most well-known of the cities is K’un-Lun, home of the Immortal Weapon known as “Iron Fist.”


A water-filled pocket dimension tied to the Bermuda Triangle, Xebel was used as a prison for rebel Atlanteans many years ago and now boasts a Homo mermanus civilization of its own.


The nine home worlds of Asgardian tradition (i.e., “The Nine Realms”) are connected by the “roots and branches” of “The World Tree,” Yggdrasil, which is actually a pocket dimension in and of itself. Yggdrasil serves as a gateway connecting our own universe (planet Earth, a.k.a. “Midgard”) with various realms in the Eä universe: AsgardVanaheimAlfheimNidavellirJotunheim and Svatalfheim from the Celestial Sea, Hel from the Underworld, and Muspelheim from the Abyss.

Zot’s World

Zot’s World is a utopian pocket dimension containing a planet resembling an idealized, “retro-futuristic” version of Earth that seemed to be stuck in the year 1965.

A virtual universe is an artificial environment, such as a cyberspace simulation, which has become sufficiently sophisticated to fully function as its own pocket universe. A virtual universe is usually by its very nature temporary, although it may eventually find a way of becoming self-sustaining.

The Grid

The Grid is a virtual-reality cyber universe initially programmed in 1983 on some former ENCOM servers. It has since been disconnected from the ENCOM mainframe and moved to a hidden location where it was further altered and expanded in secret by programmer Kevin Flynn.

The “House of M” Universe

The “House of M” was a temporary alternate reality created by The Scarlet Witch in 2005. She and several of her associates were transported to an alternate version of Earth, which existed alongside the real Earth in a parallel pocket universe. For a time, there was a certain probability that the new reality would supplant the existing Earth, but in the end, the “House of M” reality collapsed. The effects of the events that happened there did have an impact on our Earth, however.

The Matrix

The Matrix is a virtual universe created within the parallel universe of Earth-01.

Extra-spatial dimensions are like partial universes that overlay our own. (Parallel versions of them also generally overlay parallel universes, and may or may not exist in other, non-parallel conventional universes.) They are extra pockets of unseen space, energy and matter that can be accessed with the right technology. Because they rely in part on the spatial dimensions of our universe, they do not tend to have fully developed spatial dimensions of their own.

The Bleed

The Bleed, also known as “Hypertime,” is the space between universes.


Also known as “Subspace,” Hyperspace is a dimension that allows faster-than-light travel and communication without the effects of time dilation.

The Outer Void

The Outer Void is an extraspatial dimension on the periphery of the Multiverse, where all of the normal laws of nature break down. It is the original home of the Outer Gods.

The Phantom Zone

The Phantom Zone is a homeostatic continuum existing outside of conventional space/time. (It has also been called the “Buffer Zone,” the “Ghost Zone,” the “Stasis Zone” and the “Still Zone.”) It is a barren and insubstantial null area absent of any native physical material. People who travel into the Phantom Zone are no longer corporeal and exist only as metaphysical “phantasms” of their true selves. Though their minds and personalities remain intact, they can no longer physically interact with any other being. This includes direct physical contact as well as the power of speech. (Communication within the Phantom Zone is accomplished via telepathy.) As the Phantom Zone exists outside of the normal space/time continuum, those within it are no longer subject to the rigors of age or illness, rendering them effectively immortal – and they also require no sleep, food or air.


Pymspace is an extra-spatial dimension that can be accessed in various ways (including through the use of Pym Particles) to temporarily shunt mass to and from normal space.

The Quantum Zone

The Quantum Zone is a hard-to-access but nearly limitless source of potential energy. It can be harnessed by many who wield “cosmic energy” powers.

The Zero Zone

The Zero Zone appears work at the sub-quantum level to control and transcend the laws of nature. Many interdimensional portals and entire pocket realms are known to make use of Zero Zone science in ways that are nearly impossible to comprehend. Actual travel through the Zero Zone has been known to drive mortals insane.

Like extra-spatial dimensions, metaphysical planes overlay our own universe. However, metaphysical planes share abstract properties with our universe (mind, spirit, etc.) rather than physical ones (space, mass, etc.). They have their own spatial dimensions and corporeal substance, but these again are abstract and not bound by the same rules as the material world, and for this reason, they are often called “spirit worlds.”

The Astral Plane

The Astral Plane is a metaphysical plane of existence tied to physical reality, which can only be reached by mentally projecting oneself into an “astral body,” usually by the use of powerful telepathy. It is the domain of the mind and the source of all psionic energy. Some realms of the Astral Plane are accessible only to unconscious minds. These are known as “The Dreamlands” or “The Dreaming.” The member of the Endless known as Dream makes his home there. The blue Infinity Gem known as the “Mind Gem” is believed to be able to channel unlimited power from this plane.

The Elemental Plane

The Elemental Plane is the domain of elemental energies. Like the other metaphysical planes, these elements are not found in material form, but rather as raw, abstract forces. There are four primary realms within the Elemental Plane: Dimension Aero (the realm of air), Dimension Aqua (the realm of water), Dimension Ignis (the realm of fire) and Dimension Terra (the realm of earth). There are also many lesser realms. In particular, five realms have been noted at the junction of the major realms: Dimension Glaciem (the realm of ice) exists at the hypothetical intersection of Dimensions Aero and Aqua, Dimension Fulmen (the realm of lightning) represents the union of Aero and Ignis, Dimension Flexilis (the realm of plastic) is somewhere between Aqua and Terra, and Dimension Metallum (the realm of metal) lies between Ignis and Terra. Finally, Dimension Lux (the realm of light), seems to touch all of the major elemental realms and is sometimes considered a fifth major realm unto itself. The home realm of Destruction of the Endless is also located within the Elemental Plane. The red Infinity Gem known as the “Power Gem” is believed to be able to channel unlimited power from this plane.

The Etheric Plane

The Etheric Plane is the domain of the soul, the place where the “life force” of all living things resides. It is also where the souls of the dead continue to reside if they do not pass on to the Afterlife, and for this reason it is sometimes known as “The Ghost World.” The Etheric Plane is the source of all life-force based energies, including “The Force” used by Jedi and Sith, and “The Emotional Spectrum” used by Green Lanterns and their kin. Death of the Endless also makes her home within the Etheric Plane. The green Infinity Gem known as the “Soul Gem” is believed to be able to channel unlimited power from this plane.

The Lifeweb

The Lifeweb is the domain of the morphogenetic energy field that surrounds all living organisms, and the source of many plant and animal-based supernatural powers. There are four well-known realms within the Lifeweb: The Green (the realm of plant life), The Grey (the real of molds and fungi), The Red (the realm of animal life), and The Rot (a.k.a. “The Black,” the realm of disease and decay). There are also believed to be many other realms tied to other forms of life, including radiation-based, techno-organic, and many more. Desire of the Endless also makes his/her home within the Lifeweb. There is a rumored, gold-colored seventh Infinity Gem known as the “Ego Gem” that is believed to be able to channel unlimited power from this plane.

The Mystic Plane

The Mystic Plane is the domain of magical energy and the source of arcane powers. It is the realm to which all of the remaining Faerie finally retreated from Earth in the 17th century. It is also the location of the Rock of Eternity, and it has strong ties to Avalon and many other realms in the Otherworld universe. Delirium of the Endless makes her home within the Mystic Plane. The yellow Infinity Gem known as the “Reality Gem” is believed to be able to channel unlimited power from this plane.

The Shadowlands

Also known as “The Land of Nightshades” or “Shadowfell,” the Shadowlands is the domain of darkness and night. It is the source of the “Darkforce,” a mysterious energy that is not well understood. Metahumans such as Cloak and Obsidian are known to tap into the Darkforce, and it is also believed to be the source of power for vampires and other undead creatures. Despair of the Endless makes her home here. The purple Infinity Gem known as the “Space Gem” is believed to be able to channel unlimited power from this plane.

The Temporal Plane

The Temporal Plane is the domain of time. It is the source of the energy known as “The Speed Force,” which gives the Flash and other speedsters their super-speed, and the plane itself is sometimes called “The Speed Force” by them. It is also the source of precognitive powers that allow some to predict the future – although such predictions are never guaranteed. Those who enter the Temporal Plane are rarely allowed to leave it, although Destiny of the Endless does make her home in a garden there. The orange Infinity Gem known as the “Time Gem” is believed to be able to channel unlimited power from this plane.
