[[folder:Comic Books -- DC Comics]]
* Franchise/TheDCU has had many different Earths before the ''Comicbook/CrisisOnInfiniteEarths'', the ResetButton event from the mid to late 80's, and many {{Elseworld}} stories, including one where Superman turns out like [[http://static.tvtropes.org/pmwiki/pub/images/kerai/1141875127011.jpg this]].
* By far the most important AU in the DC Multiverse was Earth-Two, home of the Comicbook/JusticeSocietyOfAmerica, who would cross over with the [[Franchise/JusticeLeagueOfAmerica Justice League]] on Earth-One once a year.
* Other alternate earths in the D.C. Multiverse included but were not limited to:
** Earth-3, [[MirrorUniverse where the good guys were bad guys]] and so-forth.
** Earth-4, where characters from Creator/CharltonComics (Blue Beetle, Captain Atom, the Question, etc.) lived after D.C. had acquired their rights.
** Earth-S, where characters from Creator/FawcettComics (the Shazam Captain Marvel, the Marvel Family, etc.) lived after D.C. had acquired their rights or they'd fallen into the public domain.
** Earth-X, where characters from Quality Comics (Uncle Sam, Phantom Lady, the Human Bomb, etc.) lived, and where UsefulNotes/WorldWarII continued into the '70s.
** Earth-Prime, which was supposed to represent the "real world," and from whence the infamous Superboy Prime cometh.
** The 5th Dimension and Qward from ''Superman'' and ''Green Lantern'', respectively, which were homes to certain villains in their comics.
* ''Comicbook/CrisisOnInfiniteEarths'' supposedly did away with alternate Earths, except for a few things.
** The 5th Dimension and Qward remained, and in fact, Qward took the place of Earth-3 in establishing a place of origin for the Crime Syndicate.
** An early post-Crisis Superman story established that Superboy had existed in a Pocket Universe created by the Time Trapper simply to explain an inconsistency of the mainstream DC Universe Superman never becoming Superboy, yet the Legion of Super-Heroes still regard Superboy as actually existing and becoming one of its members.
** D.C. began labeling their high-concept imaginary stories "Elseworlds" as if to imply that they took place on alternate Earths.
** The 1996 Marvel vs D.C. crossover clearly states that Marvel and D.C. Comics take place on parallel Earths. This is important to the overall plot of the story, though it doesn't seem to have had much impact on the ongoing lives of either line of superheroes.
*** The 2003 ''Comicbook/JLAAvengers'' also says that Marvel and D.C. are parallel Earths.
** The fate of the Superman of Earth-2 was still apparent in the story ''The Kingdom''.
** D.C. eventually created Hypertime as essentially a similar device to exploring alternate versions of characters.
** And, finally, the plot of ''Comicbook/InfiniteCrisis'' made it so that the parallel Earths ''had'' to exist.
* After ''Comic/InfiniteCrisis'', the Multiverse was restored, with 52 separate realities, most of them containing versions of the {{Elseworld}} stories. So we got to see Superman fight [[Comicbook/SupermanRedSon Communist Superman]] at last.
* While a longstanding tradition at DC, the Second Wave of [[ComicBook/{{New52}} The New 52]] had the re-established Earth-2 as a focus. (Not only the ''Comicbook/{{Earth 2}}'' comic itself, but also ''Worlds' Finest'', whose stars are refugees from that reality.)
* ''ComicBook/ForeverEvil'' involves the Crime Syndicate of the re-established Earth-3 invading the main Earth.
* ''ComicBook/TheMultiversity'':
** The Earths that get their own individual issues are:
*** Earth-4, where the Creator/CharltonComics characters - Comicbook/TheQuestion, Comicbook/BlueBeetle, Comicbook/CaptainAtom, etc. - are the heroes of a ''Comicbook/{{Watchmen}}''-influenced world.
*** Earth-5, the world of [[Comicbook/{{Shazam}} Captain Marvel]] and the Marvel Family.
*** Earth-10, a world where Kal-L was found by the Nazis, and grew up to become Overman. With the help of retro-engineered Kryptonian technology - and, when he was old enough, Overman himself - the Nazis won UsefulNotes/WorldWarII. [[MyGodWhatHaveIDone In guilt over the Nazis' atrocities]], Overman turned his Earth into a pseudo-utopia; the last English-speaking rebels, [[Comicbook/FreedomFighters Uncle Sam and the Freedom Fighters]], fight Overman's Justice League.
*** Earth-16, with the children of the main DC universe's heroes and villains - Chris Kent as Franchise/{{Superman}}'s son, Damian Wayne as Franchise/{{Batman}}'s son, etc. - plus DC's '90s supers.
*** Earth-20, a [[TwoFistedTales pulp-style world]] featuring [[Comicbook/DoctorFate Doc Fate]] and the Society of Super-Heroes, who include Abin Sur's Franchise/GreenLantern, Immortal Man, the Mighty Atom, and the Blackhawks.
*** Earth-33, a.k.a. Earth-Prime, which is basically our world, with the reader being its latest superhero. [[spoiler:It's also the world of origin for the Gentry, who are designated as "Hostile Independent Thought-Forms" by the reader and his/her haunted comic book, Ultra Comics. The Gentry's creator, the Empty Hand also reigns here, as he is implied to be the personification of our real world apathy towards superheroes and comics in general who is still digesting the previous iteration of the Multiverse lost during ComicBook/{{Flashpoint}}]].
** The other worlds of the multiverse include:
*** Earth-0, the main DCU.
*** Earth-1, the world home to the ''Earth One'' line of graphic novels, with young and inexperienced versions of the main DC heroes just beginning to appear.
*** Earth-2, as featured in [[Comicbook/{{Earth 2}} the comic of the same name]], where younger versions of DC's Golden Age heroes arose in the modern day in the wake of an invasion from Apokolips.
*** Earth-3, the MirrorUniverse of Earth-0, ruled by the Crime Syndicate of America [[spoiler:until the Anti-Monitor destroyed it in ''Comicbook/ForeverEvil'']].
*** Earth-6, the world now home to the stories from ''Comicbook/JustImagineStanLeeCreatingTheDCUniverse''.
*** Earth-7 is already destroyed upon the arrival of Nix Uotan, but appears to have been a Marvel pastiche like Earth-8, below. However, pastiches of DC characters can be seen among the dead, so it's likely this Earth was a mix-up in homage to the many DC and Marvel crossover stories. The guidebook confirms that it is (or was) the equivalent to Ultimate Marvel.
*** Earth-8, a Creator/MarvelComics pastiche, for example featuring the [[ComicBook/TheAvengers Retaliators]] and the [[Comicbook/XMen G-Men]].
*** Earth-9, the Creator/TangentComics universe.
*** Earth-11, which includes [[GenderFlip female versions of the main DCU's heroes and villains, and male versions of its heroines and villainesses]]. This is a world where the Amazons of Themyscira had greater influence on society's advancement, to the point that women were given more freedom and helped shape Earth's future.
*** Earth-12, the ''Franchise/{{DCAU}}'' world, currently in the era of ''WesternAnimation/BatmanBeyond''.
*** Earth-13, home to a dark, magical Justice League called the League of Shadows, including [[Comicbook/{{Etrigan}} Superdemon]], Comicbook/{{Hellblazer}} (based on the Batmanesque version from ''Comicbok/DoomPatrol'' #53 and ''Comicbook/BooksOfMagic'' Annual #3), and [[Comicbook/DoctorFate Fate]] (the 90s version with the ankh scar). The world is in a state of perpetual twilight, there are 13 months in the year, and 13 hours in every day.
*** Earth-15, a perfect world that was destroyed by Superboy-Prime. All that's left is a Cosmic Grail that was hidden in another world.
*** Earth-17, an Earth ravaged by atomic destruction. Humanity lives in domed cities, and the Atomic Knights of Justice are led by Adam Strange.
*** Earth-18, a Western-style world featuring the Justice Riders, who ride on SteamPunk horses. On this world, the [[ComicBook/{{Legion of Super-Heroes}} Time Trapper]] froze the state of progression so that, even with many 21st Century based technological advances, society is still a frontier world.
*** Earth-19, a world currently in the era of Edwardian England, home to the Bat Man, the Wonder Woman, the Accelerated Man, and the Shrinking Man. Bruce and Diana are based on ''Gotham By Gaslight'' and ''Amazonia'' respectively [[note]]Although those books have completely different UsefulNotes/{{Jack the Ripper}}s, so can't actually be the same universe. The finale to DC's ''ComicBook/{{Convergence}}'' reveals that denizens from both worlds were present when the Multiverse was reformatted, causing the new Earth to combine elements of both[[/note]].
*** Earth-21, the ''ComicBook/DCTheNewFrontier'' universe.
*** Earth-22, the ''ComicBook/KingdomCome'' universe.
*** Earth-23, home of President Superman, where the world's greatest heroes are black (which can mean that they're black in the main DCU, as with Steel and Vixen; that a black holder of the legacy in the main DCU is Earth-23's primary holder, as seems to be the case with Green Lantern; that they're black versions of the hero, as with Superman; or that they're completely unique). The major exception is Batman.
*** Earth-26, an AlternateTooniverse where ComicBook/CaptainCarrotAndHisAmazingZooCrew reside.
*** Earth-29, the cube-shaped BizarroUniverse.
*** Earth-30, the ''ComicBook/SupermanRedSon'' universe.
*** Earth-31, a world ravaged by tsunamis and earthquakes, where modern pirates roam the seas. Captain Leatherwing and his crew of the Flying Fox act as a force for good.
*** Earth-32, a world partially based on ''Batman: In Darkest Knight''. Bruce Wayne is Green Lantern, and fights alongside heroes such as Super-Martian, Wonderhawk, and Aquaflash.
*** Earth-34, an ''ComicBook/AstroCity'' pastiche, home to [[ComicStrip/LilAbner Goodfellow]] and the heroes of Cosmoville.
*** Earth-35, a pastiche of Rob Liefeld's ''Extreme Studios'' comics, including [[ComicBook/{{Supreme}} Supremo]] and Majesty, Queen of Venus. The premier superteam of this world is the Super-Americans.
*** Earth-36, a world home to a team called Justice 9, based off ''Big Bang Comics''.
*** Earth-37, a world based off the works of author Howard Chaykin, such as ''Batman: Thrillkiller''.
*** Earth-38, a world where Batman and Superman debuted in 1938, aged normally, and had families.
*** Earth-39, a world based off the works of artist Wally Wood, home to the [[Comicbook/THUNDERAgents Agents of W.O.N.D.E.R.]]
*** Earth-40, an EvilCounterpart to Earth-20 where villains rather than heroes triumph, featuring ComicBook/LadyShiva, ComicBook/VandalSavage, Count Sinestro, Blockbuster, and Doctor Felix Faust as the Society of Super-Villains.
*** Earth-41, home to [[Comicbook/{{Spawn}} Spore]] and [[ComicBook/SavageDragon Dino-Cop]], a world where so many heroes differ in terms of style and ideology, it's as if they were each dreamed up by individuals who had [[Creator/ImageComics specific images and ideals of their heroes]].
*** Earth-42, home to imp-like versions of the Justice League known as the Li'l Leaguers.
*** Earth-43, which has a Vampire League and is home to the ''Comicbook/BatmanVampire'' Elseworlds trilogy.
*** Earth-44, the world of the Metal League, a fusion of the Justice League and the Comicbook/MetalMen, led by Doc Tornado.
*** Earth-45, an Earth where Superman as a concept became perverted and corrupted by mass marketing and turned into the hyper-edgy Superdoomsday, whom later went on a homicidal rampage killing the Supermen of other Earths before being stopped by the Superman of Earth-0 in ''ComicBook/GrantMorrisonsActionComics''.
*** Earth-47, a world where TheSixties never ended, home to the Love Syndicate of Dreamworld and immortal teenage president [[ComicBook/Prez1973 Prez Rickard]].
*** Earth-48, the new home to Lady Quark and Lord Volt. A world bred as protectors of the Multiverse, where everything is a superhero.
*** Earth-50, home to the Justice Lords from the DCAU.
*** Earth-51, the world of Creator/JackKirby's DC creations.
** The guidebook covers 45 of the Earths, leaving 7 over for other writers to develop: 14, 24, 25, 27, 28, 46 and 49.
*** In the ''ComicBook/SupermanRebirth'' story "Multiplicity", Earth-14 is home to the Justice League of Assassins, and what's seen of it suggests an AfterTheEnd ''Film/MadMax''-style world.
* In ''Comicbook/{{Convergence}}'', ComicBook/{{Brainiac}} has been collecting fragments from timelines and universes that have "ended" together on one world - ie, every DC timeline and AU prior to the ComicBook/{{New 52}} - and Telos decides to let them meet. Featured are:

* ''[[ComicBook/LutherArkwright The Adventures of Luther Arkwright]]'' is based on the premise of an infinite multiverse of parallel universes or realities which differ with each other in many things. For example, one of the main places where the action in the comic book takes place is a 20th century world where Great Britain is still ruled by a puritan government and a descendant of Oliver Cromwell. In addition, New York is New Amsterdam and the other great powers are the empires of Russia and Germany.
* Even Franchise/ArchieComics do this sort of thing, a notable example being the ''Life With Archie'' series. The storyline where Archie marries Betty is treated as a different universe from where Archie marries Veronica. The former also happens to feature a character traveling between universes!
* ''ComicBook/BlackScience'' explores infinite alternate dimensions. A disturbing number of them have some version of Grant McKay developing pillar technology. This includes a number of nonhuman Grant analogs. One theory is that the travel is easier between dimensions that have weakened the barriers by experimenting with pillars.
* Creator/MarvelComics has explicitly adopted a Multiverse as part of their canon, with "out of continuity" storylines assumed (or explicitly stated) to have happened on an alternate Earth (or alternate-wherever). The "main continuity" of most Marvel titles is labelled as taking place on "Earth-616".
** ComicBook/{{Galactus}} is the sole known survivor from the previous Big Bang-Big Crunch universe cycle, making him technically a native of an alternate universe.
** And then there's the ''ComicBook/AgeOfApocalypse'' storyline. Although it was initially an alternate ''present'' for Marvel's baseline universe "Earth-616", it became an alternate reality when Jean Grey split it off into a separate universe during the events of ''X-Men Omega''.
** The comic ''ComicBook/{{Exiles}}'' explores this idea to its fullest, having the main characters hop between different Marvel [=AUs=] and fixing problems.
** According to ''ComicBook/EarthX'', every time you alter history through time travel you create an alternate universe.
** Comicbook/ManThing's swamp is home to a [[{{Hellgate}} plot-friendly conflux]] of universes, including ComicBook/HowardTheDuck's home dimension.
* There are four known ones in ''ComicBook/PaperinikNewAdventures''. In order of appearance, they are: a universe where the [[spoiler: Evronians]] are the BenevolentPrecursors who taught science to the inhabitants of the Americas and the Vikings are the dominant power of Europe that are trying to invade (the recurring character Urk comes from there, and was accidentally pulled in Paperinik's own by the Raider); a ''Literature/TheLordOfTheRings''-like world conquered by an alternate and dimension-hopping [[spoiler: Raider]], who rules benevolently after finally ending the incessant wars; the timeline from which the alternate [[spoiler: Raider]] comes from (specifically an Alternate Universe of PK's canon future); the [[spoiler: Ultimate Universe Continuity Reboot]] gets established as one by the original PK showing up in the last issue. The story ''The Day of the Cold Sun'' specifically establishes there's an infinite number of universes, but travel between them is almost impossible due the sheer numbers of them (in that story the Raider has a device to travel between them, but after finally succeeding at charging it he gets stuck in all of them at the same time because the device couldn't choose one).
* ''ComicBook/SinisterDexter'' introduced an alternate universe, which fans dubbed the [[FanNickname Doppelverse]], around the time it [[CerebusSyndrome got serious]]. The PointOfDivergence is that in the Doppelverse, the title characters were killed while still a pair of punk kids, with the result that most of their enemies are still alive and can [[BackFromTheDead come back to make trouble]].
* ''ComicBook/JudgeDredd'':
** The entire basis for the "Helter Skelter" story arc, which featured an alternate depiction of each of Dredd's biggest enemies, [[ExpendableAlternateUniverse all of which have killed the counterpart to the original Dredd from their respective home dimensions]], teaming up to defeat Judge Dredd prime.
** There was another story arc dealing with the discovery of a MirrorUniverse called "Macro Zone Alpha" in which the city was an exceptionally polite place, and the brutal Judges were replaced by soft-spoken rehabilitation officers.
** [[OmnicidalManiac Judge Death]] and his [[EvilCounterpart Dark Judges]] originate from their own universe nicknamed "Deadworld" where living itself is considered a crime. There was also an atomic war at some point that led to the rise of a Judge system where the lawkeepers had ultimate power, but technology was noticeably less advanced than in Dredd's universe, as there were no [[MegaCity Mega-Cities]].
** There was also a time when Dredd dimension jumped [[http://dreddbanned.ytmnd.com/ and punched out Sylvester Stallone.]]
* Let's not forget how it's done in ''ComicBook/ArchieComicsSonicTheHedgehog'', where universes are known as "Zones". Beginning with the Mirror Universe with Scourge the Hedgehog, and continuing with Blaze the Cat and her "Sol Zone". And did I mention, in one "zone", Sonic is a cop who patrols between zones?
** These universes, however, were destroyed with the sol exception of the "Sol Zone" at the end of ''ComicBook/SonicTheHedgehogMegaManWorldsCollide''. ''ComicBook/SonicTheHedgehogMegaManWorldsUnite'', however, suggests that they were rebuilt into the SEGA and Capcom multiverses.

* ''Comicbook/TomStrong'' features Terra Obscura, which is an alternate Earth... but it's ''not'' in another dimension or universe. It's located at the opposite end of the galaxy from "our" earth, and is its exact double -- it's even part of a replica solar system. Tom theorizes that this is a ghost particle phenomenon on a cosmic scale. What differences there are are fairly minor, with the existence of more plentiful and more powerful science-heroes on Terra Obscura chief among them. Other than that, history went along many of the exact same beats, and thus it's not all that different from what we're familiar with (including its own version of Tom himself, Tom Strange) -- though apparently the War of the Roses swung the other way, as New York is instead called "New Lancaster".
** It's mentioned off-hand that the first time Tom Strong and Tom Strange met, it was as enemies, which means the EvilTwin angle saw some exploration as well.
* ''ComicBook/{{Zot}}'': It is left ambiguous which Earth is the real Earth, but it is hinted that Zot's world is merely our Earth with all the bad parts taken out. It becomes more evident when it is revealed that the year is always 1965.
* Issue #50 of ''ComicBook/ThePowerpuffGirls'', "Deja View" (DC run), had the girls being sucked into a vortex through their bedroom vanity mirror and transported into an alternate Townsville. It is rent asunder, which they think is the work of Mojo Jojo. But they encounter Jomo Momo, an alternate Mojo who is this alternate world's champion trying to stop the Powerpunk Girls, the alternate world's villains. The Powerpunks wind up in the true world's Townsville and have their way with it. When the girls gain Jomo's trust, they conspire to stop the Powerpunk's creator, Oppressor Plutonium, and return to Townsville to stop the Powerpunks and send them back. This was meant to be a season five TV episode but it exceeded budget, so the storyline was given to DC Comics to make as a special issue.
* Creator/AlanMoore loves using this trope when telling superhero stories, making it clear that stories with superheroes or fantastic powers would make that world radically different from ours. This includes ''ComicBook/{{Watchmen}}, ComicBook/{{Miracleman}}, ComicBook/TheLeagueOfExtraordinaryGentlemen, ComicBook/{{Providence}}''
* ''ComicBook/MightyMorphinPowerRangersBoomStudios'' is not only an alternate universe to the mainstream series, but it also has its own alternate universe where the point of divergence is Jason offering Tommy a hand of friendship. There, he refused it, rejoined Rita on his own will and proceeded to take over the world, becoming the powerful Lord Drakkon.
** Compared to the mainstream series, a few of the series seemingly ended differently. In ''ComicBook/MightyMorphinPowerRangersShatteredGrid'' we see that the Time Force Rangers are still united in the future with Wes as part of the team, Lauren Shiba leading the Samurai Rangers instead of her brother Jayden and [[spoiler:Lord Drakkon ends up killing Tommy.]]

* ''Webcomic/AxisPowersHetalia'' fanfic ''[[https://www.fanfiction.net/s/11886910/1/Gankona-Unnachgiebig-Unità Gankona, Unnachgiebig, Unità]]'' is set in an alternate universe where [[spoiler:the countries have more power and are able to bend the rules more than in canon. Romano proves this by overseeing a [[{{Polyamory}} polyamorous]] marriage between Germany, Italy, and Japan.]]
* ''ComicBook/PowerGirl'' fanfic ''Fanfic/AForceOfFour'' is set on an alternate [[Franchise/TheDCU DC Universe]]. The Golden Age Franchise/{{Superman}} dies in lieu of Pre-Crisis Supergirl as fighting the Anti-Monitor, TheMultiverse survives the ''ComicBook/CrisisOnInfiniteEarths'' and ComicBook/PowerGirl becomes the protector of Earth-Two.
* ''Fanfic/CoOpMode'': Of a kind wherein James exists since birth in the Wormverse. A closer example could be that [[SentientCosmicForce Ga]][[GeniusLoci ia]] exists, and thus is at work with helping parahumans (like ''[[spoiler: Contessa/Fortuna]]'') in defeating [[spoiler: Scion]].
* ''Fanfic/AgentLokiInternationalManOfMayhem'' takes an alternate route from the ending of ''Film/{{The Avengers|2012}}'' to continue with Loki being used as a TokenEvilTeammate by S.H.I.E.L.D.
* ''Fanfic/BatmanBeyondRevisited'' has Bruce Wayne die in his final battle with ComicBook/TheJoker, and Terry [=McGinnis=] is replaced with an OC, runaway Jake Vance, who is recruited by the inheritors of Wayne Manor, Dick Grayson and the Oracle Barbara Gordon.
* ''Fanfic/CelestialWarriorMoon'' is an alternate retelling of ''Franchise/SailorMoon'' which makes the monsters a lot more threatening and the girls transform into armored [[LadyOfWar ladies of war]]. Also, Tuxedo Mask is Franchise/{{Batman}}.
* ''Fanfic/DeathsChild'': Lily Potter is Death's one day of mortality... Which changes everything.
* ''Fanfic/ChildOfTheStorm'' has the basic premise of Thor having been incarnated as James Potter first time round on the humility thing. This went about as well you'd expect, with the trauma of being violently murdered, then watching helplessly as his wife was murdered driving him nuts, necessitating a mind wipe and a return to square one. Also, [[spoiler: Lily turns out to have been first cousin once removed of Jean Grey and accidentally called upon the Phoenix to protect Harry - which explains the incendiary component of the protection - and is not exactly dead, as such]], which, needless to say, changes everything. It grows into a massive InterContinuityCrossover, sticking the ''Franchise/MarvelCinematicUniverse'', ''Franchise/HarryPotter'', ''Literature/TheDresdenFiles'', and ''{{Series/Smallville}}'' in a blender and is spliced with elements of ''Creator/MarvelComics,'' ''Creator/DCComics,'' and ''[[Series/Merlin2008 Merlin]]'' to create something entirely different. There's even a few sly references to ''Literature/GoodOmens.''
* ''Fanfic/EggmanGenerations'': The ending of ''VideoGame/SonicGenerations'' leads the past and future Eggman into a white void, where they encounter the Eggman from Sonic 2006, as well as Dr. Eggman Nega and a fusion of Robotnik from Sonic SATAM and Adventures of STH, the latter two coming from alternate universes.
* ''Manga/{{Evangelion 303}}'': In this alternate world Second Impact did not happen, Seele is a terrorist organization and does not plan an AssimilationPlot, there are no [[HumongousMecha giant robots]] or [[{{Robeast}} alien monsters]], the Children are in their twenties and pilot war planes, Kaworu is a human being, apparently Rei is unrelated to Shinji…
* ''Fanfic/HarmonysWarriors'' is an incredibly expansive one, with the WesternAnimation/MyLittlePonyFriendshipIsMagic universe combined with the Franchise/MarvelCinematicUniverse.
* ''Fanfic/HereIGoAgain'' takes place in an alternate universe starting when Obi Wan tells the council about Anakin's nightmares about Shmi.
* Fanfic/HedgehogOfDarknessAU is an AU where sonic is created like shadow,using dark gaia as a DNA donor
* ''ComicBook/{{Supergirl}}'' fanfic ''Fanfic/HellsisterTrilogy'' is reality similar to the Earth-One universe which was born when the Anti-Monitor was defeated early on.
* ''Fanfic/{{HERZ}}'': In this story Third Impact never happened. The divergence was created when [[spoiler:Rei felt Shinji's despair at being unable to save Asuka. Rather merging with Lilith's body she absorbed it and flew to help him. She shattered the bakelyte encasing Shinji's giant robot and both hurried to help Asuka.]] Twelve years later Misato leads an organization tasked with preventing the proliferation of Evangelion technology, Shinji and Asuka are married and raising their child and SEELE is still plotting TheEndOfTheWorldAsWeKnowIt.
* ''[[http://www.fanfiction.net/s/8629492/1/iSwear iSwear]]'', an ''Series/{{iCarly}}'' fanfic, starts with Carly entering an alternate universe, and every time she loses consciousness she is automatically evicted from one universe and pushed onto another in a manner similar to ''Series/QuantumLeap'' and ''Series/{{Sliders}}''. The horror kicks in when you find out that [[spoiler:other versions of Carly have been doing the same thing and that many have died]] due to ending up in dangerous {{Crapsack World}}s.
* [[http://www.fanfiction.net/s/7314071/1/Just_One_Big_Happy_Kingdom Just One, Big, Happy Kingdom]] is a ''Series/{{Merlin|2008}}'' fanfic in which an eighty-year-old Merlin decides to teach his younger self a lesson by putting him in a mirror universe ("Not-Camelot") and put Not-Merlin in the normal Camelot. It's one of those mirror everybody-is-his-opposite universes.
* ''Fanfic/MassEffectClashOfCivilizations'': Aside from the obvious (the UNSC in place of the Systems Alliance, the Covenant species existing, the whole ''Franchise/{{Halo}}'' side of the crossover), in this universe the Council lifted the ban on opening closed relays several years before the start of the story. In canon ''Franchise/MassEffect'', this never happened, and even during the trilogy the law against opening relays was still upheld.
* ''Fanfic/MyBravePonyStarfleetMagic''. Because the author hated ''WesternAnimation/MyLittlePonyFriendshipIsMagic''[='s=] universe too much to use anything from it. At least until it [[CrossOver crosses over]] with the ''FIM''[='s=] universe about three-quarters through. They are even merged into one kingdom at the end.
* Also, ''Starfleet Humans'' takes place in the same alternate universe that ''[[WesternAnimation/MyLittlePonyEquestriaGirls Equestria Girls]]'' took place in. However, Mykan is on record as saying that it is an alternate continuity that takes place near the end of MLP's 3rd Season.
* ''[[http://www.fanfiction.net/s/1594758/1/STRANGE_PATHS NIGHTWALKER: STRANGE PATHS]]'' is a ''Anime/{{Nightwalker}}'' fic which basically has Riho as a [[OlderThanTheyLook 140 year old vampire]] and Shido who starts out as a human detective.
* FanFic/TheOdyssey, an TabletopGame/{{Exalted}} fanfic. It's notable for both its quality and the fact that the point of divergence has not yet become apparent. [[spoiler:Something happened to the Fivescore Fellowship, though.]].
* Two of these exist in ''Fanfic/PhoenixsSSBBCaseFiles'', named Alternate Turnabout and Alternate Turnabout 2. The first has Larry Butz working as a defense attorney, with Adrian Andrews at his side, while 2 features Franziska von Karma and assistant Dick Gumshoe working for the Wright and Co. Law Office.
* The ''Fanfic/PonyPOVSeries'' has such a thing. It's explained that all the worlds diverged from the [[TheEarthPrimeTheory Heart World]] (implied to be the actual shows' timeline) and are effected by changes there, but can break off and continue on their own in the event the change in the Heart World is so great said universe can no longer harbor the connection. The ones the series itself focuses on are its main timeline and the [[BadFuture Discorded Timeline]], a VillainWorld ruled by Discord, but we also see a ''lot'' of alternate timelines which Princess Luna refers to as "possibilities and impossibilities". Applejack gets to see quite a few of them on two separate occasions, the one that means the most to her being the Orangejack universe, where she never left Manehatten. [[spoiler:She eventually gets to meet Orangejack and they team up to fight Nightmare Mirror, Applejack's own SuperpoweredEvilSide who may or may not be another alternate version of her. It also turns out Orangejack is an Element Of Generosity and there are universes were Applejack was one of the other Elements as well, all of which are summoned to fight Nightmare Mirror.]] There's also a universe were Rainbow Dash turned into Nightmare Manacle, another where Pinkie Pie turned into Nightmare Granfalloon, and another were the mane cast are the [[Series/MightyMorphinPowerRangers Mighty Morphing Power Ponies]] fighting a Goldar version of Gilda. Oh and [[spoiler:Pinkie Pie is actually the G3.5 Pinkie Pie and is how she is thanks to being left pretty much untouched by a CosmicRetcon that turned that universe into the G4 universe.]]
* ''Blog/ThePredespairKids'' was originally meant to be a prequel to the events of ''VisualNovel/{{Danganronpa}},'' but it branched off into its own universe with [[spoiler: Mukuro Ikusaba pulling a HeelFaceTurn before the Tragedy ever takes place]]. Although even before then, there were some pretty big divergences from canon here and there, such as [[GamerChick Chiaki]] being a RidiculouslyHumanRobot jointly built by Chihiro and Kazuichi.
* ''Fanfic/RealityIsFluid'' starts out with the USS ''Bajor'' being tasked with testing a new sensor array designed to detect and observe alternate universes. Two of the universes detected are an AU where the Federation apparently lost the Dominion War, and the Franchise/StarTrekNovelVerse (the fic is based in the ''VideoGame/StarTrekOnline'' timeline).
* ''FanFic/RidingTheDragon'' diverts the ''TabletopGame/BattleTech'' universe by having political intrigue change the course of House Kurita in the early 31st century.
* ''Fanfic/ScarredSurvivors'' is a retelling of the Ah! My Goddess manga. A wish has enslaved Belldandy to a depraved pedophile. Urd enlists the help of a soldier in order to save her, a Navy SEAL by the name of Keiichi Morisato.
* ''Fanfic/TheSonOfTheEmperor'' mixes the real world with the world of WesternAnimation/MyLittlePonyFriendshipIsMagic. This results in an Alternate Universe where the ponies grow to the size of horses and have been used for centuries in warfare, mytical creatures like griffons are commonplace and magic exists.
* ''Fanfic/StreetsOfRageSaga'', a 10-story saga based on the ''VideoGame/StreetsOfRage'' game series (both the canon trilogy and several fan-made games and remakes based on said trilogy), takes place in a setting based on but highly different from the canon. Just a few brief examples, with the canon information in parentheses: Axel [[ParentalAbandonment lost his father in a fire]] that was set by the man who would later become TheDragon for the first story's BigBad (in canon, no mention is made of Axel's family members); Blaze comes from a DoomedHometown that was razed by TheSyndicate (in canon, the only back-story on her is that she was a rookie cop who quit alongside Axel and Adam because of the force's corruption); and Mr. X is a U.S. senator with the full name of George Xetheus (in canon, his real name wasn't divulged and his role as a CorruptCorporateExecutive was only hinted at in canon and expounded on in Bombergames' remake).
* The {{Fanfic/Uplifted}} series does this, by showing what happens when Humanity is uplifted circa 1942 by the desperate Quarians with the intention of using them to retake Rannoch.
* ''Fanfic/WithStringsAttached'' is set on another planet in an alternate universe. Additionally, the four visit three other universes (including one set in a 1950s New York, more or less); the Fans are watching from their universe; the Dalns gods inhabit yet another universe; and Jeft comes from still another.
* This trope is likely to be used by '''any''' IntercontinuityCrossover fanfic in which the melded continuities would otherwise contradict one another.
** Certain ''Franchise/PowerRangers''/''Franchise/SuperSentai'' crossovers treat both series as alternate universes to each other - fitting, considering that one lends source material to the other. This is especially noticeable in stories where a PR team is placed opposite the Sentai team that served as its source, for example, [[http://www.fanfiction.net/s/2889432/1/Magiranger-vs-Mystic-Force this]] ''Series/PowerRangersMysticForce''/''Series/MahouSentaiMagiranger'' story.
* {{Wiki/Nickelodeon Fanon}} has various universes other than their main universe, The Prime Universe. The universes mostly contain of [[AlternativeCharacterInterpretation alternate versions]] of characters from the Prime Universe.
* ''FanFic/TheBoyWithTheMagicNotebook'' suggests this is where the people Maxwell summons with his notebook come from.
* An ''Series/{{ER}}'' fanfiction series titled "Dreams That You Dare To Dream" had several of the main characters leaping to alternate universes in which several of the show's major changes never took place--Carol did die from her suicide attempt from the first episode, Susan Lewis never left town and married Mark Greene, etc. Another one set on New Year's Eve 1999, titled "Countdown", took a similar form, though it only focused on the typically unpopular Kerry Weaver.
* ''FanFic/TheKanyeverse'' is one for ''VideoGame/ShinMegamiTenseiNocturne''.
* ''[[https://www.fanfiction.net/s/10541838/1/Alternate-Reality Alternate Reality]]'' sees [[Franchise/SonicTheHedgehog Shadow the Hedgehog]] wake up in an alternate reality where, among other things, [[CheerfulChild Tails]] is painfully shy and quiet, [[MarriedToTheJob Knuckles]] doesn't give a fig about the Master Emerald, and [[TheHero Sonic]] is a vicious borderline-sociopath.
* The roleplay [[Roleplay/DCUnitedWeStand DC: United We Stand]] is set in one of the multiple alternate universes created by the events of [[ComicBook/FiftyTwo "52"]].
* ''Fanfic/TheReactsverse'':
** ''Fanfic/WeissReacts'' and ''Fanfic/LucinaReacts'' are Alternate Universes of ''WebAnimation/{{RWBY}}'' and ''VideoGame/FireEmblemAwakening''. More details are available on their respective pages.
** ''Homura Reacts'' is this to ''Anime/PuellaMagiMadokaMagica'' where all of the Puella Magi survive to the present day.
* ''FanFic/SonicXDarkChaos'' is this to ''Anime/SonicX'', thanks to a few points of divergence in the back story of ''Sonic X'' Season 3. The biggest change is that Cosmo's race was destroyed by their own creations rather than by the Metarex. This ultimately causes several more outside factions to get involved in the Metarex arc, with ''[[CrapsackWorld very]]'' bad consequences for the galaxy.
* It's never been clear whether the ''Series/{{Supernatural}}'' episode "The End" took place in the actual future, an alternate timeline, or a construct designed to be as distressing to Dean as possible. ''Fanfic/DownToAgincourt'' takes the view that the timeline really exists, and now that Dean's time has "caught up" (mostly, we think), it's more of an alternate universe than a BadFuture.
* ''FanFic/TotalShuffledIslandSeries'' is this to ''WesternAnimation/TotalDrama''. Every contestant that has competed in the first season all the way up to the sixth has had their introductory season changed around, leading to a different run of events such as different teams winning a challenge or different couples forming.
* The ''VideoGame/{{Undertale}}'' fandom is a breeding ground for alternate universes. Some of these include:
** Underswap, where the main character pairs switch places in terms of personality. Toriel is the Queen hunting down humans while King Asgore treats the player like a surrogate child; Papyrus is a lazy slacker while Sans is an excitable sentry; Alphys is head of the Royal Guard while Undyne is a bookish scientist; Mettaton is a melancholic snail-farmer while Napstablook is the Underground's celebrity, and [[BigBad Flowey]] is usually swapped with [[CloudCuckooLander Temmie.]]
** Underfell, the DarkerAndEdgier MirrorUniverse where everyone except Flowey wants you dead.
** Storyshift, another universe where characters switch places. Most notable for [[spoiler:Asriel and Chara]] taking the place of Papyrus and Sans, respectively.
** [=OFFTale=], a {{Crossover}} where [[VideoGame/{{OFF}} the Batter]] [[http://offtale-au-sc.tumblr.com/post/149025778294/neutral-run-parts-links gets to continue his sacred mission in the Underground,]] and things [[OffTheRails start changing fairly rapidly.]]
** Disbelief Papyrus [=AUs=], where [[spoiler:Sans dies protecting Snowdin instead of Papyrus in the Genocide Run, and so Papyrus becomes the FinalBoss.]]
** Reapertale, where the characters become various [[AnthropomorphicPersonification anthropomorphic personifications]] (most notably, Toriel is the Goddess of Life while Sans and Papyrus are TheGrimReaper).
** Mafiatale, where the monsters are a gang operating out of 1930s America.
** Outertale, where the monsters were exiled to a far-off planet and the player is an astronaut.
** [[https://tratserenoyreve.tumblr.com/post/135227136600/i-had-a-thought-the-thought-continues-here The Thought]], which explores what might have happened if [[spoiler:Sans killed the player as soon as they left the Ruins.]]
** Then there's the Error Universe, created from a copy of the game that was mangled beyond recognition and which spawned Error Sans (who wants to end the Multiverse entirely). And last but not least, there's [=HELP_Tale=], a universe populated entirely by [[EldritchAbomination horrors]] [[spoiler:formed from the amalgamated bodies of every version of a character in the multiverse, jammed together.]] [[http://undertaleau.tumblr.com/aumasterlist And that's not nearly all of them.]]
** Baby Blasters, an off shoot of the Gasterblaster AU, where young Sans and Papyrus can change shape to resemble the Gasterblaster weapons, with the flagship fic being Fanfic/{{Trust}}, as well as a thriving [[http://babyblasters.tumblr.com/ Tumblr Community]].
* ''Series/BuffyTheVampireSlayer''/''ComicBook/{{Supergirl}}'' crossover ''Fanfic/TheVampireOfSteel'' is set in an universe similar to Pre-Crisis DC where Buffy and her friends also exist.
* ''FanFic/WithThisRing'': Justified that OL is stranded in a universe where there are [[FantasyKitchenSink superheroes, magic, aliens, and etc.]]. Though there are interesting differences from our world (see DifferentWorldDifferentMovies): there is a Pope Pius XIII; UsefulNotes/RichardDawkins apparently doesn't exist or didn't became very important (likely because of the universe's aforementioned FantasyKitchenSink which makes Dawkins' outspoken skepticism totally irrelevant), and the [[TheWarOnTerror September 11 attacks]] never happened because the UsefulNotes/SovietInvasionOfAfghanistan was avoided.
** There are apparently two universes the stories take place in- the main one, and a second world where Paul takes more actions that could be termed [[Franchise/MassEffect renegade]], such as turning Sportsmaster into a construct, trying to steal tech from the New Gods, injecting himself with Venom Buster, and eventually begins calling himself Grayven.
** And there is the [[MirrorUniverse Crime Syndicate]] universe (aka Earth -14), which take place before and after the events of ''WesternAnimation/JusticeLeagueCrisisOnTwoEarths''. Here, Paul is a Blue Lantern, who goes by the name of Power Ring and is a Made Man of Ultraman, and is technically babysitting the more adolescent tempered Young Offenders in check.
** It's also WordOfGod that there is a version of Paul in the WesternAnimation/TeenTitansGo universe...and his sheer ''revulsion'' towards said universe resulted in him getting a ''[[ThePowerOfHate Red]]'' [[ThePowerOfHate power ring]].
** The Fool's Canon arc brings into picture of other alternate Pauls with different power rings in the wider multiverse.
*** An Anti-Green Lantern Paul, who is a reluctant villain that is [[BlessedWithSuck being controlled by his power ring]], in a version of the {{Franchise/DCAU}} in which it includes Cyborg being a founding member of the Justice League and a abundance of sidekicks closely participating in the League.
*** A Red Lantern Paul exists in the regular ''WesternAnimation/TeenTitans'' universe.
*** An Indigo Lantern Paul who is in [[spoiler:ComicBook/TheBoys]] universe.
* There are several in the ''Manga/SgtFrog'' ''FanFic/YinAndYangSeries'', both made by the author herself and by fans of the fic. It helps that several major characters are reality-warpers.
* ''Fanfic/ReverseFallsAU'' depicts a MirrorUniverse where the twin protagonists Dipper and Mabel are evil teen telepaths running a CircusOfFear.
* ''FanFic/{{crawlersout}}'': Odd case. Fem!Harry's house is connected to two separate universes: one is set in her original time, years after the defeat of Voldemort, where the plot of the original ''Literature/HarryPotter'' series happened (just with Harry as a girl). The other is an alternate universe set in the 1930s, where the point of divergence is Harry taking in a young Tom Riddle Jr. a few years before he is set to go to Hogwarts. The main plot occurs in the latter setting, where Harry is raising Tom and interacting with some of the most prominent figures in this era (more specifically, Gellert Grindelwald, with Albus Dumbledore slated to appear later), with occasional dips into the former setting.
* ''Fanfic/ConstantsAndVariables'': With Elizabeth in control of her abilities and [[spoiler:accidentally passing on some of her quantum powers to Harry]], alternate worlds are brought up and presented in the story.
** For Christmas break, Elizabeth takes Harry to an alternate version of Rapture, a world where Plasmids and Fontaine and all of the factors that led to the canon-Rapture’s demise never happened and the city has been thriving up to present day.
** After finding out that Narcissa drugged her tea with veritaserum, Elizabeth decided that showing Narcissa the result of her and her family’s loyalties, taking them both into a world where Voldemort won and rules supreme. Not much is shown, the only things they could see being Hogsmeade (now nothing but ashes) and a mass graveyard where the Shrieking Shack used to be. The graveyard was dug by neutrals and were used to bury the failed LaResistance while the neutrals where killed and thrown in a ditch when Voldemort and his followers inevitably turned on them.
** When Elizabeth and Harry learn about the Philosopher’s stone, they venture into an alternate universe where the first year has not commenced yet, sneaking into the corridor where the stone is meant to be hid in before all of the obstacles and traps are laid out. When the Dumbledore of that universe finds them, he mentions that he is expecting the “Girl-Who-Lived” to be introduced to the school, that universe’s version of Harry being female.
** After spending the minimum month with the Dursley’s, Elizabeth takes Harry to an alternate New York within ''Film/ThePurge'' universe.

[[folder:Films -- Animation]]
* It's implied that the two ''Disney/{{Cinderella}}'' sequels are set in different universes.
* In ''WesternAnimation/MyLittlePonyEquestriaGirls2013'', Twilight Sparkle goes to one where the ponies are humans in high school, accessed via a MagicMirror.
* ''WesternAnimation/ShrekForeverAfter'' takes place in a universe where [[BigBad Rumpelstiltskin]] is crowned king, and many of Shrek's former allies have been changed in one way or another (I.E. Puss in Boots becoming the ogre clan's housecat and Donkey being treated as a regular mule).
[[/folder]]

[[folder:Films -- Live-Action]]
* ''Film/TheOne'' is a cross between this and ConservationOfNinjitsu. The villain is traveling around to the various universes killing all the alternate versions of himself so he'll have all the power that would otherwise be spread out between them. Since the hero is one of the alternates, he winds up with bigger and bigger slices of the power pie as well, making for a ''battle royale'' when it's down to just the two of them.
* ''[[Film/SuperMarioBros Super Mario Bros. The Movie]]'' posits a "sub-dimension" created through the impact of the meteorite into earth that caused the extinction of the dinosaurs. The dinosaurs continued to evolve in this sub-dimension in the city of "Dinohattan", a city mirroring New York City.
* In ''Film/Cube2Hypercube'', the hypercube transects parallel universes. The characters don't realize this until they start running into duplicates of themselves and each other. Exploited by one character who uses them as a [[IAmAHumanitarian human food source]].
* Apparently the setting of [[spoiler: ''Film/{{Parallels}}'']] leans heavily on this trope, with entire branches of {{The Multiverse}} to be shunted about in.
[[/folder]]



[[folder:Live-Action TV]]
* ''Series/{{Andromeda}}'' did several episodes exploring Alternate Universes in various ways: as a NearDeathExperience, and as a result of one character's ability to view potential futures. The most noteworthy was "The Unconquerable Man", which was an entire ClipShow playing out events from the show's history with a different lead character.
* Birthdayverse in ''Series/{{Angel}}''
** Illyria mentions being able to live seven different lives at once in different universes back in her days, including a universe made [[RunningGag entirely of shrimp]]. She tired of that one quickly.
* ''Series/{{Awake}}'' is about a detective experiencing parallel realities after a car accident, one in which his wife has died, one in which his son has died. He uses tenuous cross-universe clues to solve crimes. The validity of the realities and the possibility that one is a subconscious response to trauma is always in question. The series ends with [[spoiler:the possible introduction of a third reality in which both wife and son are alive]].
* The Wishverse in ''Series/BuffyTheVampireSlayer'' (and the [[CuckooNest asylum-universe]] of "Normal Again")
** These eventually became a running gag on the show, with Anya often mentioning universes she could potentially send people to: the universe of infinite Wednesdays, the universe without shrimp, the universe of ''nothing but'' shrimp...
** At first, "Superstar" appears to take place in an alternate reality where Jonathan is the eponymous MartyStu, but it later turns out that he had cast a spell that altered reality itself.
** There's also the universe as it was Before Dawn and Post-Dawn.
* ''Series/{{Charmed}}'' employs a ''literal'' MirrorUniverse, which could be accessed through a mirror.
* The ''Series/{{Community}}'' episode "Remedial Chaos Theory" features the group rolling a die to choose who will go to the door to get the pizza. Abed warns that this will create 6 (actually 7) alternate universes. Everyone else of course dismisses this, but we the audience get to watch each one unfold. The differences ranges from different characters hooking up, mental break downs occurring, everyone having an awesome night, and ''everything going to shit''. [[spoiler: The versions of the characters in the universe where everything went to shit end up being recurring villains.]]
%%* ''Series/DarkShadows'' may well have brought this trope to television for the first time. -ZCE
* ''Series/DoctorWho'':
** "Inferno", an alternate totalitarian Britain (branching off at least around the 'defence of the republic act, 1943'), which is in a still greater rush to get free power from tapping the magma of the Earth. It is destroyed, with the Doctor able to just avert the similar events happening a few hours later in his 'home' alternate. Not bad at all.
** "Rise of the Cybermen"/"Age of Steel" has the TARDIS fall through a crack in time and land in a universe where the Cybermen were being created on Earth. Mickey explicitly references how common the trope is in [[ComicBookTropes comics]]. This universe crossed over again in "Army of Ghosts"/"Doomsday" and its effects continued to be felt in ''Series/{{Torchwood}}'''s "Cyberwoman" episode. And in the finale of Series 4 of ''Doctor Who''.
** In "Turn Left", Donna Noble has an entire alternate universe built around her, where she never met the Doctor, and he consequently dies after the events of "The Runaway Bride." It does not fare well. In fact, the universe without the Doctor is pretty much a terrible place to be.
* The Alternate Universe on ''Series/{{Fringe}}'' is a world where pockets of time and space become unstable due to [[spoiler: Walter's kidnapping of Peter by crossing to the other side]]. In the AU, there are many details that differ from the characters' home universe, such as Martin Luther King Jr. being on the American $20 bill and the World Trade Centers still standing and [[spoiler: Walter never went insane (and never hard parts of his brain removed), and is now the Secretary of Defense and head of their Fringe team, which takes far more drastic action to combat the far more drastic "Fringe Events" that occur "over there".]] Also, they're keen to show the presence of [[ZeppelinsFromAnotherWorld zeppelins]], just so you know it's an alternate universe.
* ''Series/GameOfThrones Ascent'', which follows the plot and events of the TV show (such as the death of Rakharo or Xaro Xhoan Daxos' betrayal) but incorporates elements of the novels: like Vaes Tolorro or Catelyn taking two Freys as wards.
* ''Series/{{Glee}}'':
** One of the Christmas Specials features a world in which Artie never got on a wheelchair. As a result, there's no glee club, and Mr. Schue is an alcoholic and still married to his manipulative wife Terri. Also, Rachel never went to New York to work on Broadway and remained in Lima working as a librarian, Puck and Finn never graduated and remained being [[JerkJock Jerk Jocks]], Kurt didn't graduate either because, without the support and help of the glee club, he was bullied twice as much, and Quinn, without Artie's help and support, never could recover from the psychological trauma of being stuck on a wheelchair after her car crash and committed suicide.
** There's also the episode in which [[ADayInTheLimelight Tina]] is knocked unconscious and she wakes up in a world where she has traded places with Rachel, that is, Tina is the club's main lead and singer while Rachel has to stay in the back and never gets a solo.
* ''Series/{{Grimm}}'': There's at least one alternate universe where the [[OurWerebeastsAreDifferent Wesen]] run free and probably from their come from. In this universe Wesen can not [[GameFace vogue]] and humans live like in the DarkAges.
* ''Series/{{Hounded}}''
** When Rufus Hound is presenting a new show, he always gets pulled into a parallel universe by his Future Self.
* ''Series/KamenRiderDecade'' uses Alternate Universes for its main premise. The main cast travels through various alternate universes which are modified versions of the previous Kamen Rider shows, varying from ones that're essentially the same as the originals but with [[TheOtherDarrin different actors]], to ones with [[KidHero de-aged protagonists]] or [[HighSchoolAU ones in high school]] or Dystopias.
* ''Series/KamenRiderDragonKnight'' uses the concept of alternate universes, accessible through mirrors. The Earth Kamen Riders are chosen because they are genetic doubles of the original Kamen Riders from the alternate universe of Ventara.
* Sci-fi series ''Series/{{Lexx}}'' made this its staple. The first season of the show involved the characters jumping through an inter-universe rift twice, and in the second season once at the beginning, before the entire Light Zone was wiped out in the second SeasonFinale, forcing the Lexx (and a large amount of particle matter from the zone) to get forced back out into the other universe.
* The season 1 finale of ''Series/TheLibrarians2014'' has Flynn and Eve travel through three alternate realities, after [[spoiler:[[BigBad Dulaque]] messes with the Loom of Fate]]. In each of the three realities, one of the Librarians-in-Training is the Librarian, since Flynn never took the job offer 10 years ago. Strangely, Eve appears to have been recruited as the Guardian at the same time, but has since been killed under the same circumstances (stabbed by Excalibur during the events of the pilot). Each of the three realities is a CrapsackWorld. At the end of the episode, [[spoiler:all three help Flynn and Eve restore the Loom, even though this would mean that they themselves would be written out of existence. Their prime counterparts don't remember a thing]].
** Stone!Librarian world: Stone failed to prevent the full return of magic to the world and is running around the world, containing the worst of the magical problems, while countries are being engulfed in conflicts. This version of Eve used to be Stone's lover.
** Ezekiel!Librarian world: Ezekiel's attempt to handle the House of Refuge crisis has GoneHorriblyWrong, and the world is undergoing a [[ZombieApocalypse Ghost Apocalypse]], as Team Ezekiel (he found a way to make money as the Librarian) struggles to find a solution. This version of Eve was Ezekiel's mother figure.
** Cassandra!Librarian world: Magic is everywhere. Cassandra herself is a powerful wizard, having used magic to get rid of her brain tumor, which affected her personality. The world is coming to an end, and she plans to escape reality in a manner similar to Morgan le Fay with a small group of followers. This version of Eve was Cassandra's friend, although she disapproved of the use of magic. After Eve's death, Lamia became the new Guardian.
* ''Series/LoisAndClark'' had an Alternate Universe in which Lois was lost in a jungle and Clark had not made himself into Superman.
** This does allow the protagonists to discredit the BigBad, who tries to expose Superman's secret identity. It's kinda hard to argue that Clark Kent is Superman, when both of them are standing right there.
* Season 6 of ''Series/{{Lost}}'' features an alternate universe where 815 never crashed, and many other details are different. WordOfGod has it that neither timeline should be called "alternate" or "parallel" as those words imply that one is more real than the other. [[InsistentTerminology Flash-sideways]] has been decided to be the proper term. People in the flash-sideways actually retain memories from the other timeline, with Desmond seemingly able to switch between both willingly. [[spoiler:[[DeadAllAlong The finale blows the flash-sideways out of the water entirely.]]]]
* ''Series/{{Misfits}}'':
** The fourth episode has Curtis go back in time to the night he and his girlfriend Sam were busted for drug possession (the reason why he was on community service with the gang). After various failed attempts, Curtis does prevent the bust and him and Sam escape from the police, however it resulted on an Alternate Universe in which he was never on community service, which results in Kelly, Simon and Alisha being murdered by the probation worker, something Curtis had prevented from happening in the pilot.
** Episode 2.6: A world in which a man who can manipulate lactose reveals their powers to the world, but later when more people with much more impressive abilities he is regarded as a joke in comparison, resulting on him going psycho and murdering Alisha, Nikki, Kelly and Nathan.
** And then there's also that episode of Series 3 in which an old man gains Curtis' ability to travel in time and goes back to Nazi Germany to kill UsefulNotes/AdolfHitler. However, he fails, Hitler obtains his phone and uses it to make gigantic technological advances that resulted in the Nazis winning WWII.
* Homaged in ''Series/MysteryScienceTheater3000'', "Last of the Wild Horses", where Dr. Forester and TV's Frank get to quip at the movie, and evil Mike and Bots watch on from Deep 13.
* In ''Series/{{NCIS}}'', a generally reality based show, features a series of clips from Alternate Universe based on a series of What-If moments. What if Kate hadn't died? [[spoiler: Tony and Kate get married and have a kid. Yay! Ziva goes from crazy assassin to even crazier assassin. Aww.]] What if Gibbs also hadn't killed Pedro Hernandez? [[spoiler: His demons consume him, he quits NCIS sooner, he becomes a (likely) alchoholic, shuts himself in his basement for months, ''[[FelonyMisdemeanor is rude to Abby]]'', [[ArsonMurderAndJaywalking and Abby/McGee and Tony/Kate become canon.]]]] What if Shannon and Kelly hadn't died? (Warning: ''major'' TearJerker behind those spoilers. [[spoiler: [[TearJerker Gibbs dies fighting overseas. No matter what, he lost his family.]]]]
** Parent series ''Series/{{JAG}}'' also had an {{Elseworld}} episode, appropriately named "WhatIf".
* "Ace" Rimmer (what a guy!) on ''Series/RedDwarf'' came from an Alternate Universe, and travelled between dimensions. The Red Dwarf crew themselves had previously travelled into an Alternate Universe in the episode "Parallel Universe". Some episodes have featured similar alternate versions of characters and events, but were a result of time travel rather than passing into another Universe (notably "Timeslides" and "Inquisitor").
** Rimmer enters a mirror universe in "Only The Good...", where he's captain of the ship, [[BrainyBrunette Kochnski]] is a DumbBlonde, and [[TheDitz The Cat]] a genius professor.
** [[spoiler: The dream world from "Back To Earth" is treated like this after the crew wakes up, and they find it hilarious that the people in it think they're real and the Red Dwarf crew are the fictional ones...]]
** The books delve into this too. While multiple universes are established in ''Better Than Life'', they really come into play in ''Last Human'' and ''Backwards''. ''Last Human'' occurs when the crew return from Backwards Earth to the wrong universe and try to track down Lister's other self. In ''Backwards'', Ace Rimmer is given a backstory behind Project: Wildfire and turns up to save the crew. Bonus points for the fact that both books, having each been written by Grant and Naylor separately, take place in alternate universes to each other.
* In ''Series/{{Seinfeld}}'' episode #137 "The Bizarro Jerry", Elaine is in a similar social circle where the Kramer equivalent is neat, George's is responsible, etc.
* In the ''Series/{{Shadowhunters}}'' episode "This World Inverted", Clary visits an alternate dimension where the Shadowhunters haven't needed to exist for centuries.
* Nate experienced an Alternate Universe during a NearDeathExperience in an episode of ''Series/SixFeetUnder''.
* The series ''Series/{{Sliders}}'' used this as its central premise.
* ''Series/{{Smallville}}'':
** An interesting subversion: Clark [[CuckooNest wakes up in a mental asylum]]; apparently, he started having delusions of superdom in high school, and his "saving" of Lex in the first episode actually cost Lex his legs. Oh, and Chloe is a freaking nutcase. Of course, it was all a delusion caused by an escaped Phantom that attacked him in his barn and invaded his mind. John Jones (the Martian Manhunter) helped him escape by entering the illusion (as another inmate), and capturing the creature in a Kryptonian crystal.
** ''Noir'': ComicBook/JimmyOlsen wakes up in a FilmNoir universe.
** Season 10 had an Alternate Universe as a major plot line: Clark discovers a kryptonian artifact called a "mirror box" and when activated it takes him to a world where the Kents never adopted him, but instead was raised by Lionel Luthor and goes by the name "Clark Luthor". Clark Luthor himself is brought to Clark Kent's world and causes no end of trouble before the original Clark manages to switch them back. Then it turns out the alternate Lionel managed to come through to the main world with Clark, taking the place of the original Lionel (who was dead) with a story that he'd faked his death. Then Clark Luthor uses ''his'' mirror box to come back and send our Clark to his world, where he helps the alternate Jonathan reconnect with Martha, and convinces Clark Luthor to try and use his powers for good, rather than live in Lionel's shadow.
* Much of the Australian-Polish TV series ''Series/{{Spellbinder}}'' takes place in a parallel world, which, initially appears to be primitive but is later revealed to be taking place AfterTheEnd (an unknown Spellbinder experiment resulted in a global disaster). Temporary rifts occasionally open between our world and the world of the Spellbinders. The sequel ''Spellbinder: The Land of the Dragon Lord'' involves a machine, built by a Chinese inventor from yet another reality, that allows him to travel to any parallel world. The inventor and his companion from our world end up visiting several more worlds, including a world where much of humanity has been wiped out by a plague, and the cure that saved a tiny fraction of people also made them immortal and unable to reproduce, and another AfterTheEnd world, where remnants of humanity try to rebuild after a devastating RobotWar. The titular Land of the Dragon Lord is an alternate China, where ancient aesthetics mix with advanced light-based technology.
* ''Series/StargateSG1'' has had many different alternate universes. Oftentimes, the "alternate" Samantha Carter is not in the military and is engaged/married to the "alternate" Jack O'Neill. Alternately Daniel Jackson was never part of the Stargate Program. More often or not, when this is used, Earth is under imminent Goa'uld attack.
* ''Series/StargateAtlantis'' also does this, though the details vary, and the universes aren't ''usually'' quite the CrapsackWorld versions that ''SG-1'' is fond of.
** In the episode "[=McKay=] and Mrs. Miller", alternate Rodney is a really nice guy with lots of friends and alternate Sheppard is a member of Mensa, greatly annoying everyone with his egoism. In our universe, Rodney is the egoist one, Sheppard is a nice guy who took a Mensa test but turned down the offer to join.
** In "The Daedalus Variations", a dimension-travelling ''Daedalus'' starship from an alternate universe pops up, and the team is trapped onboard when the ship continues to jump through alternate universes randomly. These include one where the planet Atlantis is located on hadn't formed into a stable planet, and one where they're attacked by an unknown group of hostile aliens. They can't shut down the dimension jump but they can reverse its direction, allowing them to get back before the engines quit on them and stranding them permanently.
** And another is shown in the penultimate episode "Vegas". There, Sheppard is a homicide detective with massive gambling debts. He couldn't be included in the team because the stunt he pulled off in Afghanistan got him dishonorably discharged instead of getting ReassignedToAntarctica in time for the pilot. Rodney is more likable (though one scene suggests that he's simply better at keeping a lid on his ego) and the Wraith already made an attempt at culling Earth just to be repelled by the control chair in Area 51. Oh, and Todd got so delirious from starvation he's speaking in rhymes.
* ''Series/{{Supernatural}}'':
** An Alternate Universe seems to be seen in the episode "What Is And What Should Never Be", but it's really all in Dean's head and everything is his perception -- Mary's perfect, Sam and Dean are a bit wussy and the family is like any other. In his fantasy, his mother Mary and Sam's girlfriend Jessica were never killed by Azazel, so the Winchester family live perfectly normal lives and his Dad died peacefully. As Dean is utterly unhappy there, it seems he wants a extremely codependent relationship with Sam and the wracking memories of his family.
** A real Alternate Universe, or rather a series of them, pops up in the episode "Mystery Spot" thanks to a [[GroundhogDayLoop repeating time loop]] in which Dean keeps dying. The iteration before the final time loop lasts months instead of the standard day, resulting in a dark, isolated Sam.
** Later in the episode "It's a Terrible Life", where Dean is a Marketing Director for a firm and Sam is a techie in the same building with no memory of their hunter life beforehand apart from a few dreams, it's revealed that this was all [[SecretTestOfCharacter a ruse from an angel]] to show Dean hunting is in his blood and he will always find a way to be a hunter. This is also a play on the WonderfulLife trope.
** The second AU episode took place in the sixth season, where the brothers are sent to a universe [[note]]which is basically our [[RealLife world]] with a bit of hyperbole[[/note]] where Supernatural [[NoticingTheFourthWall is just a TV show]] filmed in Canada, in which Sam and Dean are played by Jared Padalecki and Jensen Ackles, and there is no magic, demons, angels, monsters, or any supernatural beings at all.
** And then there's "My Heart Will Go On", in which the Titanic never sank, somehow causing the Winchesters to own a Mustang, Bobby and Ellen to be married, and Celine Dion to be a lounge singer in Quebec.
** The birth of Lucifer's son by a human woman causes the fabric of the universe to tear, creating a portal to an alternate universe known as "Apocalypse World". It's an AfterTheEnd dimension where the forces of heaven and hell are locked in eternal combat and human civilization has been reduced to ashes.
* In ''Series/TheTwilightZone'' episode "The Parallel (1963)" an astronaut orbits the Earth a few times then lands in a world that is almost identical to the one he left but has subtle differences, he's a colonel instead of just a major, the president isn't Kennedy, etc. Then he wakes up in a hospital bed and it starts to look like it was AllJustADream, [[spoiler: before NASA receives a radio transmission from his counterpart.]]
* Almost all of the Heisei ''Franchise/UltraSeries'' (that is those from the 1990s onwards) take place in universes separate from the default Showa universe. This tends to result in things like monsters having different origins and the backstories of the Ultras being changed.
* ''Series/VR5'''s MissingEpisode, "Parallel Lives" had Duncan wake up one morning to find himself in a universe where Sydney, rather than her sister, had died in a car crash years earlier (of course, it eventually turned out that neither sister had actually died; both the car crash and the parallel universe were [[CuckooNest complex VR hoaxes]]. The episode was intended to test the viability of replacing the central character for the second season, a possibility which became moot when the series was not renewed).
* ''Series/WizardsOfWaverlyPlace'' had an episode where Alex goes through a mirror and enters a parallel universe where nearly everything is about her and in her favor.
* ''Series/XenaWarriorPrincess, Series/HerculesTheLegendaryJourneys'' use a mostly standard MirrorUniverse: Good characters become Evil, shaven characters become bearded etc. But regular Iolaus is a good, shaven, competent warrior and regular Joxer is good, shaven and incompetent; in the Mirror-verse, they are both good and shaven, but Iolaus is incompetent and Joxer is competent. There are some weird rules for the two universes. If a person (or a god) dies in one universe, he also dies in the other. Unless they happen to be ''not'' in their universe at the moment. This happened to [[spoiler:the alternate Iolaus]] who was trapped in an "in-between" world when [[spoiler:"our" Iolaus took a knife in the gut]]. Also happened to [[spoiler:Hercules]], as his double [[spoiler:the Sovereign]] was killed while in this "in-between" world.
* The second season of ''Series/TheFlash2014'' introduces Earth 2, an alternate world with many of the characters having duplicates. It's stated that there are an infinite number of universes, but this is the only one that appears to have a direct line to Earth 1 via the breaches that have resulted from [[spoiler:the paradox singularity that opened in the season 1 finale]]. When traveling between the universes, characters experience glimpses of other alternate worlds (read: shows). The overall technology level of Earth 2 is higher than that of Earth 1, partly thanks to the S.T.A.R. Labs particle accelerator working successfully (as far as the public is concerned), although much of the tech has a {{Zeerust}} feel. Additionally, {{Atlantis}} is a real place there. The Flash of that world is not Barry Allen (who is just a CSI on Earth 2) but Jay Garrick (his nickname is Crimson Comet instead of Scarlet Speedster). There is also Gorilla City in a tropical rainforest, a refuge for intelligent gorillas. Meanwhile, [[Series/{{Arrow}} Oliver Queen]] never made it off Lian Yu, his role as Starling City's protector having been taken up by his father, known as the Hood.
** The crossover with ''Series/Supergirl2015'' establishes that that show exists in the same [[TheMultiverse multiverse]]. Also, the same can be retroactively said about [[Series/TheFlash1990 the 1990 Flash series]].
** Earth 3 is mentioned in season 2 finale, which is the world where [[spoiler:the real Jay Garrick (Henry Allen's double)]] is from.
* In ''Series/TheOuterLimits'' episode "In Another Life", a man named Mason Stark is about to commit suicide, when he suddenly finds himself transported to another reality, pulled there by his more successful double (usually referred to as Stark), who has invented a device called the quantum mirror. Stark explains that he was using the mirror to meet his doubles from multiple universes in order to find out what his life could have been like. Then one of the doubles (known as Mace) murdered his wife and went on a killing spree. Stark has determined that Mason and Mace are from nearly identical universes, with the only difference being that Mason chose to try to shoot himself, while Mace opened fire on his coworkers. After finding himself in this universe, the insane Mace is trying to "put things right" by killing those, whom he shot in his own reality. In the end, the psychotic Mace and the cold-blooded Stark end up transported to other universes: Mace ends up in Mason's moments before the gun goes off, while Stark ends up facing off cops with a still-smoking gun (this ends predictably). Mason gets a happy ending, inheriting Stark's fortune and getting a second chance with the double of his deceased wife.

[[folder:Video Games]]
* The ''Tyranny of King Washington'' downloadable content for ''VideoGame/AssassinsCreedIII'' features the player character waking up in an alternate universe in which his mother is still alive, he never joined the Assassins, and George Washington went mad with power after acquiring some LostTechnology and declared himself King of America. In addition to the alternate historical elements, there are some supernatural powers present as well, truly separating the setting of ''Tyranny'' from the main ''Assassin's Creed'' setting, which is LikeRealityUnlessNoted.
* ''VideoGame/BioShockInfinite'': One of the primary themes focused upon. Sidekick Elizabeth can open "Tears", which allow access to Alternate Universes. Most of them only have very minor differences- items placed in a different locations- or, as Elizabeth gives an example, tea instead of coffee. Others have major differences, such as a key gun runner for the rebels being killed off early, or RebelLeader Daisy Fitzroy [[spoiler:having become a conqueror just as bad as [[BigBad the Big Bad, Comstock]].]] The end of the game reveals that [[spoiler:Comstock is actually an Alternate Universe version of protagonist Booker Dewitt, having become a hypocritical DarkMessiah after accepting the baptism that Booker refused.]]
* Makoto's Story "Slight Hope" in ''VideoGame/BlazBlueContinuumShift'' has her accidentally travelled to an alternate history world whereby Noel wasn't alive and it took place 3 days prior to her own timeline. Rachel ultimately explained this to Makoto and guided her back to her own timeline. Even in Litchi's story, she could sense an alternate universe happening.
** ''VideoGame/BlazBlueCentralFiction'' takes place in one, due to the influence of the Embryo. Most characters just go around living their lives normally; only a few are aware of it, such as Relius (who is performing research into its nature). [[spoiler:Act 2 reveals that it is the same time and same place, but with different "causality". Whatever that means.]]
* ''VideoGame/ChronoCross'' had alternate universes replacing time travel as the main hook.
* The original ''VideoGame/CrazyTaxi'' has "Another Day" mode. Where in the normal mode most customers want to travel in a certain direction which leads to the cabbie going in a counter-clockwise direction around the circuit, in "Another Day", the customers usually want to travel to a destination in the opposite direction, causing the cabbie to go in a clockwise direction around the circuit.
* ''[[VideoGame/DongDongNeverDie Dong Dong Never Die's]]'' plot is some alternate universe of ''Film/Terminator2JudgmentDay'', where the John Conner role is filled by [[TheChosenOne publicly-acknowledged Chosen One]] Dong Dong and the advanced Terminator sent to kill him isn't a shapeshifter, but does celebrate its victories by drinking water through what appears to be a gas mask and singing "[[Music/RKelly I Believe I Can Fly]]".
* The DLC for ''VideoGame/DragonAgeOrigins'' entitled ''The Darkspawn Chronicles'' pitches the idea of a world where TheHero died near the beginning of the game, thus leaving [[TheWoobie Alistair]] to save the day. [[spoiler:It does not end well.]]
* ''VideoGame/DragonQuestVI'' features the world that the TheHero comes from and the world referred to as the Phantom Realm. [[spoiler:Except it's the "Phantom Realm" that's really the real world, while the other world is the [[DreamLand Dream World]].]]
* The areas Yaschas Massif and Academia in ''VideoGame/FinalFantasyXIII2'' have alternate versions that appear after solving paradoxes in the timeline, and are marked with an X in the year name (ex. 01X AF). You can still go back to the original universe, though.
* In the second installment of the "Timeline" mod trilogy for ''VideoGame/HalfLife1'', Gordon Freeman is transported to a parallel Earth where the US never rebelled (the major superpowers are the British Empire, the Soviets and the Japanese), and an ice age began some 300 years earlier, threatening human survival. That world's Gordon Freeman has failed, so our world's equivalent is sent to stop the Xen invasion there (as well as an invasion of time-travelling Nazis from our dimension).
* ''VideoGame/InfiniteCrisis'' the video game is set in the DC multiverse, with characters from six Earths colliding:
** Earth-0 (Prime), the main DC universe.
** Earth-13 (Arcane), a HeroicFantasy-themed universe.
** Earth-17 (Atomic), where Kal-El's arrival on Earth during the UsefulNotes/ColdWar triggered a [[AfterTheEnd nuclear holocaust]]
** Earth-19 (Gaslight), a 19th century {{steampunk}} universe.
** Earth-43 (Nightmare), a horror universe where the heroes have been transformed into monsters.
** Earth-44 (Mecha), a world where the heroes are {{Ridiculously Human Robot}}s.
* Nearly every character from ''Franchise/KingdomHearts'' is an alternate version of his/her Disney or Final Fantasy counterpart (otherwise the game would run into some ''serious'' continuity problems). This is implicitly stated in [[Film/{{Tron}} Space Paranoids]].
** Technically, Auron might be an exception to this, as he did die and pass on to the afterlife in ''Final Fantasy X'' only for Hades to bring him back from the dead to complete a task. He even expressed his former role as a guardian to Sora. The statue containing his free will also echoed his memories from the events of ''Final Fantasy X''.
* ''VideoGame/KirbyAndTheAmazingMirror'' takes place in another literal mirror universe (akin to the ''Charmed'' and ''Red Dwarf'' ones above), parallel to Dreamland and containing mirror versions of Meta Knight, Kirby, and, [[spoiler: as revealed in the Dededetour mode of ''VideoGame/KirbyTripleDeluxe'', King Dedede]].
* ''Franchise/TheLegendOfZelda'' has plenty of alternate universes to choose from: Due to the timeline shenanigans of ''VideoGame/TheLegendOfZeldaOcarinaOfTime'', there are at least three alternate versions of Hyrule: One where Ganondorf was stopped before he could claim the Triforce, one where Ganondorf did claim the Triforce (and was stopped by Link), and one where Ganondorf defeated Link. There are also many "realms" such as the Sacred Realm, where the Triforce is usually kept (although at some points it was known as the Dark World.) There is also a [[VideoGame/TheLegendOfZeldaTwilightPrincess Twilight Realm]], the world that [[VideoGame/TheLegendOfZeldaTheMinishCap the Minish]] come from, [[VideoGame/TheLegendOfZeldaALinkBetweenWorlds Lorule]] and others.
* Based on what has thus far been fan-translated of ''Anime/MagicalGirlLyricalNanohaAs: The Battle of Aces'', it takes place in an alternate universe where [[spoiler: Reinforce I/Eins survives and the corrupted Book of Darkness creates "Dark Pieces" of selected cast members ([[DemotedToExtra sorry, Arf and Yuuno]]) to get its own back again.]]
* The ''Mega Man'' series has two universes: the main one (''[[VideoGame/MegaManClassic Classic]]'', ''[[VideoGame/MegaManX X]]'', ''[[VideoGame/MegaManZero Zero]]'', ''[[VideoGame/MegaManZX ZX]]'' and ''[[VideoGame/MegaManLegends Legends]]''), and the alternate one (''[[VideoGame/MegaManBattleNetwork Battle Network]]'' and ''[[VideoGame/MegaManStarForce Star Force]]''). The difference between these two timelines is that the latter has internet technology prosper instead of robotics (as was the case in the former).
** In a strange way, the alternate universe also rewrites most of the robot masters who were Mega Man's enemies into potential allies, the most notable being Guts Man and Search Man, both whom are enemies in the mainline series, but consistent allies in the alternate timeline.
* The ''VideoGame/{{Neptunia}}'' games all have been set in a universe similar, but different from the Gameindustri of [[VideoGame/HyperdimensionNeptunia the first game]]. With only Neptune, Vert, Blanc, Noire, IF, Compa, Histoire and (most of the time) Arfoire as {{The Constant}}s:
** ''VideoGame/HyperdimensionNeptuniaMk2'' is a ContinuityReboot that occurred because Nepgear, the protagonist of that game (and sister of the protagonist of the other games), wasn't born yet and because the ending of the first game ended with the resident godesses [[BroughtDownToNormal willingly relinquishing their godhood]].
** ''VideoGame/HyperdimensionNeptuniaVictory'' while it starts in the same universe as ''mk2'', winds up with Neptune going to a parallel Gameinsustri based on TheEighties (called the Ultradimension, in contrast to the Hyperdimesnion of the last 2 titles). And while Noire, Vert and Blanc have dimensional counterparts that are still the [=CPUs=] of their respective lands, Neptune doesn't and Planetune's CPU of that universe, Plutia, is a different person entirely. [[spoiler: That is not to say that Neptune herself doesn't have a dimensional counterpart there]].
** ''VideoGame/HyperdimensionNeptuniaProducingPerfection'''s universe seems to be set in a universe based on the Ultradimension, but with Plutia nowhere to be seen and Neptune being Planetune's CPU there.
** ''VideoGame/HyperdimensionNeptuniaReBirth1'' is a remake of the first game, but is set in a different universe from it (a notable difference being that the CPU Candidates, including Nepgear, can be recruited in this game), likewise ''VideoGame/HyperdimensionNeptuniaReBirth2SistersGeneration'' is a remake of ''mk2'' and this is set in a universe independing of that universe and the universe of the original game (though it's debatable if it's set in the same universe as ''Re;Birth 1''). This is also in effect for ''VideoGame/HyperdimensionNeptuniaReBirth3VGeneration'', as it is set in a different universe than the original ''Victory'', but does follow ''Re;Birth 2'' chronologically just as ''Victory'' follows ''mk2''.
** ''Hyperdevotion Noire: Goddess Black Heart'' not only has a different protagonist (Noire, Lastation's CPU), but even the continent has a different name (All other games have the continent be called "Gameindustri", this one is called "Gamarket")
** And finally ''VidoeGame/MegadimensionNeptuniaVII'' has not one, not two but '''[[RuleOfThree three]]''' parallel universes as its setting, including Hyperdimension [[spoiler:though both of the other two are eventually revealed to be the creation of the BigBad of the game]]. As for chronological placement, the game is canonically set after the events of ''Victory''[=/=]''Re;Birth 3'', but due to how the game references past games (and the goddesses have CharacterDevelopment more in line with their ''Re;Birth'' counterparts than their original selves), it seems to be a sequel to ''Re;Birth 3'' rather than ''Victory''.
* The games of the ''VideoGame/PhantasyStar'' series span different universes: the original series of 8-bit and 16-bit {{Role Playing Game}}s take place in the Algol solar system, while ''VideoGame/PhantasyStarOnline'' takes place entirely on and in orbit above the planet Ragol. The ''VideoGame/PhantasyStarUniverse'' series, meanwhile, takes place within the Gurhal system. Then there is ''VideoGame/PhantasyStarZero'', which takes place on Earth and the Moon in the distant future, which brings us to ''VideoGame/PhantasyStarOnline2'', which takes place in a completely different solar system than any of the previous games.
* ''VideoGame/PhantasyStarOnline2'' also has its own set of alternate universes. There is our universe, a parallel universe which is home to a TwentyMinutesIntoTheFuture Earth and Moon, and Omega, a MedievalEuropeanFantasy CrapsackWorld that functions more like a proper AU, including being home to alternate universe counterparts of characters seen in the Oracle universe.
* ''Franchise/{{Pokemon}}''
** The Distortion World in ''[[VideoGame/PokemonDiamondAndPearl Pokémon Platinum]]'' is one of these. It is home to Giratina. Dialga, Palkia and Arceus are also implied to live in their own dimensions as well.
** ''VideoGame/PokemonBlackAndWhite'' establishes the reason for having OneGameForThePriceOfTwo as because of this trope--the other version is in fact a parallel universe to the one you're playing, and the histories of a few areas and characters are different. Using the Entralink you can visit the other world and see the changes. It may also explain how you can get multiple members of otherwise SingleSpecimenSpecies. ''Sun/Moon'' takes this further by allowing you to travel to the opposing version post-game via [[OurWormholesAreDifferent an Ultra Wormhole]] at the versions' respective Altars.
** The alternate universe explanation is also used for the existence of [[SuperMode Mega Evolutions]] in ''Omega Ruby and Alpha Sapphire'', remakes of ''VideoGame/PokemonRubyAndSapphire'', as implied in the Delta Episode of ''ORAS''. This may also explain the existence of ''Pokémon'' remakes in general, though CuttingOffTheBranches and MergingTheBranches are also in effect.
*** [[ForWantOfANail The reason for the split?]] According to Zinnia in the Delta Episode, it was [[spoiler:the firing of AZ's ultimate weapon 3,000 before the events of ''VideoGame/PokemonXAndY'']]. As all titles starting with Gen VI use the Mega Evolution gameplay mechanic, they are assumed to belong to this second timeline, and ''VideoGame/PokemonSunAndMoon'' complicates things further with an appearance by [[spoiler:Salon Maiden Anabel]], who is suggested to have [[spoiler:[[TrappedInAnotherWorld "fallen" into that world]] from the one that the original ''[[VideoGame/PokemonRubyAndSapphire Emerald]]'' (and the rest of the pre-Gen VI games) took place in, or at least a world of a very similar nature and history]].
*** This also implies that spin-off game series like ''VideoGame/PokemonMysteryDungeon'' and ''VideoGame/PokemonRumble'' are part of [[TheMultiverse the multiverse]]. [[note]]Despite not being part of the mainline series, the [[VideoGame/PokemonColosseum Orre]] [[VideoGame/PokemonXDGaleOfDarkness games]] and ''VideoGame/PokemonRanger'' do share continuity with these titles, simply existing in geographically isolated regions, though Sinnoh is said to be the closest region to Fiore, the setting of the first ''Pokémon Ranger'', and Oblivia, the setting of ''Guardian Signs'', is far to the south of both Fiore and Almia. They can be treated as {{Gaiden Game}}s, with their [[NonLinearSequel exact placement in the overall timeline]] unknown.[[/note]]
*** ''WebVideo/GameTheoryWebShow'' took this one step further and theorized that [[UpToEleven every copy of every game takes place in a different universe]]. After all, [[spoiler:what's the device that the Devon Corporation uses to send the world-ending meteorite to another universe called?]] The Link Cable. What's the real world device used to trade and battle between two different players' save files called? [[FridgeBrilliance The Link Cable.]]
** In addition to the above, ''Sun/Moon'' also introduces the [[EldritchAbomination Ultra Beasts]], which turn out to be [[spoiler:extradimensional Pokémon]] from an EldritchLocation called Ultra Space.
** To take things even further, ''VideoGame/PokemonUltraSunAndUltraMoon'' take place in an alternate universe from the original ''Sun and Moon'' and feature an entirely different story ([[InSpiteOfANail though these changes are largely only in regards to]] [[spoiler:the goals of the Aether Foundation and the role of the cover legendary]]) as well as the ability to ride Solgaleo and/or Lunala through Ultra Wormholes into various other parts of Ultra Space located light-years away. Additionally, the post-game scenario, Episode RR, features a new incarnation of [[VideoGame/PokemonRedAndBlue Team]] [[VideoGame/PokemonGoldAndSilver Rocket]] (Team Rainbow Rocket), which is a VillainTeamUp led by Giovanni consisting of alternate universe counterparts of ''all'' the series' main villains prior to Gen VII ([[MyFriendsAndZoidberg and Faba]]). As it turns out, the villains each hail from a world where [[TheBadGuyWins they actually succeeded in their plans]] (or, more specifically, succeeded because the {{Player Character}}s of their games didn't exist), only to be swept up by an Ultra Wormhole (or an implied Giratina in Cyrus's case) and recruited by Giovanni. It should be noted that Ghetsis appears to have been taken from some version of the events of ''Black/White'' and not [[VideoGame/PokemonBlack2AndWhite2 their sequels]] judging by his attire [[note]]though he does recognize Colress, who debuted in ''[=B2/W2=]'', on sight, indicating Colress had already joined Team Plasma by that Ghetsis's point in time[[/note]], whereas Maxie and Archie appear with their original designs in lieu of the newer ones their ''OR/AS'' counterparts sport.
* The [[ExcusePlot plot]] of the ''VideoGame/{{Portal 2}}'' [=PeTI=] DLC involves this. Earth-Prime's version of Aperture is nearly broke, so they decided to cut test chamber construction costs by sneaking the designs into alternate versions of Aperture, letting ''them'' build it, then stealing them back. You can either play the part of a test chamber designer with the new level editor, or a test subject traveling between universes to test the new chambers. You end up running into various versions of Cave Johnson, all of whom are still running tests (and probably pulling the same scheme) and crazy to some extent (save for the one who [[VideoGame/HalfLife1 stopped the resonance cascade experiments after buying Black Mesa]]).
** Amongst the other notable universes you encounter are a universe ruled by giant mantis-men, a universe ruled by an evil, sentient cloud god, a universe where Cave Johnson created ''Robo-Cop'', a universe made of money, and a universe with an evil version of Johnson where asparagus is the primary food source of the planet.
* The ''VideoGame/{{Resistance}}'' games take place in a setting where after UsefulNotes/WorldWarI Germany's economy wasn't totally devastated, therefore UsefulNotes/AdolfHitler never rises to power and there was no UsefulNotes/WorldWarII. Instead, creatures known as Chimera take over the entirety of Europe and by the sequel have wiped out the US.
* The ''Dawn of Victory'' mod for ''VideoGame/SinsOfASolarEmpire'' has its premise based on an AlternateHistory where the course of UsefulNotes/WorldWarII is changed by the arrival of a powerful alien race known as the Scinfaxi (inspired by Creator/HarryTurtledove's ''Literature/{{Worldwar}}'' series). After losing much territory to the invaders, the main world powers manage to develop nuclear weapons and beat them back to the Southern Hemisphere. They then rebuild and consolidate their power. Eventually, the Northern Hemisphere is divided between the Soviet Union, the Greater German Reich, and the Democratic Federation. They manage to develop interstellar flight and settle other worlds. After the Scinfaxi resume their advance, the human powers evacuate the remaining population from Earth and nuke the entire planet from orbit. Fast-forward a few centuries. The three main human nations (as well as many smaller states) are spread out over many star systems and vying for domination. Meanwhile, the Scinfaxi (a vast interstellar empire) are preparing to strike again.
* The two ''VideoGame/{{Sonic Rush|Series}}'' games feature a parallel universe. The first game takes place in Sonic's universe, which is slowly merging with Blaze's. The second game takes place in Blaze's universe... which is apparently a giant ocean.
* The ''VideoGame/SuperRobotWars'' games are set in an Alternate universes for each of the series portrayed in it(the alternate, of course, being that they're all happening at the same time in the same place). Each game or series is, additionally, an alternate universe from each other. Then there is the Original Generation universe, which contains all the original characters and mecha from the other games and then some, which also has its own MirrorUniverse, the Shadow-Mirror universe, which is itself the Original Generation version of the Shadow-Mirror universe from ''VideoGame/SuperRobotWarsAdvance''. Confused yet? We haven't even gotten to the ''VideoGame/EndlessFrontier''!
** In ''VideoGame/SuperRobotWarsL'', ''Anime/MacrossFrontier'', ''Anime/VoltesV'', and ''[[Anime/{{Iczer}} Fight! Iczer-One]]'' all come from one universe and end up somehow Folding into another, which is where all the other series take place.
** The baseline ''VideoGame/SuperRobotWarsV'' universe contains the NCC and [[Manga/{{MobileSuitCrossboneGundam}} late Universal Century]], while a second contains the [[Anime/{{MobileSuitGundamSEEDDestiny}} Cosmic Era]], [[Anime/{{MobileSuitGundam00}} Anno Domini]], the ''Anime/MartianSuccessorNadesico'' timeline, ''Anime/CrossAnge'', ''Anime/Zambot3'', and ''Anime/Daitarn3'', and a third has early UC, ''FullMetalPanic'', the ''[[Anime/ShinMazinger Mazingers]]'', ''[[Manga/GetterRobo Getter Robo Armageddon]]'', and ''Anime/NeonGenesisEvangelion''. Dimensional rifts similar to the ones in ''VideoGame/SuperRobotWarsZ'' send the protagonists and their allies bouncing back and forth between them.
** ''VideoGame/SuperRobotWarsX'': As far as Earths outside of Al-Warth are concerned, there are several universes:
*** "The World of War": Consisting of the Universal Century ''Franchise/{{Gundam}}'' series. The Earthnoid members of ''Reconguista'' originally thought that they came from another universe, only to find out that the Reguild Century used to be the Universal Century.
*** "The World of Revolution": Contains ''Anime/{{Daitarn 3}}'', ''Anime/CodeGeass R2'', ''[[Anime/MobileSuitGundamWing Gundam Wing]]'' and ''Anime/AuraBattlerDunbine''.
*** "The World of Peace": Made up of ''[[Anime/TheBraveExpressMightGaine Might Gaine]]'', ''Anime/ShinMazinger'', and ''[[Anime/MashinHeroWataruSeries Wataru]]''
*** Others: ''Anime/NadiaTheSecretOfBlueWater'' and ''Anime/BuddyComplex''.
* In ''VideoGame/TalesOfXillia2'', much of the plot revolves around the exploration and destruction of alternate universes, which are threatening the original universe simply by existing.
* ''VideoGame/TheWorldEndsWithYou'' has ''Another Day''. This takes place in a world where Neku and his friends [[spoiler: never died]], Shuto is TheHero with Neku as TheLancer, Tin Pin Slammer is SeriousBusiness, Eri's parents decided to call her Shiki for some reason, and [[ArsonMurderAndJaywalking Neku is less emo]].
** And, mind-bogglingly, despite what the game says, it actually has some bearing on the main plot. [[spoiler:Joshua]] flees to that universe after [[spoiler:shielding Neku from Minamimoto's Lv. ''i'' Flare]]. Whereupon he challenges Another Day!Neku to a BossRush to kill time.
** It also seems to cross over into TheMultiverse with certain people as they can go to other dimensions, and even meet themselves if they aren't careful.
* ''VideoGame/WorldOfWarcraft: Warlords of Draenor'' involves former Warchief of the Horde Garrosh Hellscream going back in time, creating one of these, and then making a portal [[TheMultiverse between the universes]].
** Garrosh didn't create the alternate universe. It already existed as an alternate with a few key differences from ours. He just changed it MORE and connected it with ours. The alternate Draenor is actually a mix of this trope, ''TimeTravel'', AND ''SetRightWhatOnceWentWrong''.
** ''World of Warcraft'' in general messes with this as there are many cannon timelines that the Bronze Dragonflight watch over, including and not not limited to a timeline where Thrall was never born, an alternate future where Deathwing succeeded in destroying all life on Azeroth including himself, and of course the after mentioned alternate Draenor that the Fifth expansion takes place in.
* ''Videogame/AgentsOfMayhem'' takes place in an alternate universe of the ''Videogame/SaintsRow'' series that was created in one of the endings of ''Videogame/SaintsRowGatOutOfHell'' in which Gat wishes for a CosmicRetcon. Certain characters from that series appear in [=AoM=] and are even playable ([[TheSmartGuy Pierce Washington]] and [[HuskyRusskie Oleg Kirrlov]] are now "Kingpin" and "Yeti" respectively).

Added DiffLines:

* ''ComicBook/MightyMorphinPowerRangersBoomStudios'' is not only an alternate universe to the mainstream series, but it also has its own alternate universe where the point of divergence is Jason offering Tommy a hand of friendship. There, he refused it, rejoined Rita on his own will and proceeded to take over the world, becoming the powerful Lord Drakkon.
** Compared to the mainstream series, a few of the series seemingly ended differently. In ''ComicBook/MightyMorphinPowerRangersShatteredGrid'' we see that the Time Force Rangers are still united in the future with Wes as part of the team, Lauren Shiba leading the Samurai Rangers instead of her brother Jayden and [[spoiler:Lord Drakkon ends up killing Tommy.]]

* In ''Series/TheOuterLimits'' episode "In Another Life", a man named Mason Stark is about to commit suicide, when he suddenly finds himself transported to another reality, pulled there by his more successful double (usually referred to as Stark), who has invented a device called the quantum mirror. Stark explains that he was using the mirror to meet his doubles from multiple universes in order to find out what his life could have been like. Then one of the doubles (known as Mace) murdered his wife and went on a killing spree. Stark has determined that Mason and Mace are from nearly identical universes, with the only difference being that Mason chose to try to shoot himself, while Mace opened fire on his coworkers. After finding himself in this universe, the insane Mace is trying to "put things right" by killing those, whom he shot in his own reality. In the end, the psychotic Mace and the cold-blooded Stark end up transported to other universes: Mace ends up in Mason's moments before the gun goes off, while Stark ends up facing off cops with a still-smoking gun (this ends predictably). Mason gets a happy ending, inheriting Stark's fortune and getting a second chance with the double of his deceased wife.
