History Main / DimensionalTraveler

* The Monsters in ''WesternAnimation/MonstersInc'' are interdimensional travelers who use closet doors to travel between the human and monster worlds.

* ''Literature/TheCosmere'' has worldhoppers, people who travel between the Cosmere's various worlds. Note that despite their differences the worlds are physical planets that exist in the same universe, meaning that one ''can'' physically travel between them with a spaceship capable of FasterThanLightTravel, but those only start popping up in stories set very late in the timeline. Prior to that, most worldhopping is done by traveling through another dimension called the [[MentalWorld Cognitive Realm]]. Since the Cognitive Realm is shaped by human perception, the vast amounts of empty space where no-one lives and aren't ''being'' perceived don't exist, so it becomes possible to simply ''walk'' between planets. Some of the more prominent worldhoppers in the Cosmere are:

* The ''WesternAnimation/FamilyGuy'' episode "[[Recap/FamilyGuyS8E1RoadToTheMultiverse Road to the Multiverse]]" has Brian and Stewie becoming this.

* Discord from ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' has the ability to quite easily tear open portals to other universes with his talons. This could very well be an explanation as to why he makes references to other stories, such as ''Franchise/StarWars'' and ''Literature/HarryPotter''.

** Rick is this due to his "Portal Gun". This technology is unique to Rick and his alternate selves, and is one of a number of reasons many aliens in the setting want to capture him.

* ''The Underwood See'': After spending the first two books of the trilogy dealing only with each other's AlternateTimelines, Nadia and Alaric meet Aldous U, a much more experienced traveler who's personally catalogued dozens of worlds.

* ''Literature/TheCosmere'' has worldhoppers, people who travel between the Cosmere's various worlds. Note that despite their differences the worlds are physical planets that exist in the same universe, meaning physical travel between them is possible, but would require FasterThanLightTravel to accomplish. Instead, worldhopping is done by traveling through another dimension called the [[MentalWorld Cognitive Realm]]. Since the Cognitive Realm is shaped by human perception, the incomprehensible distances between planets are compressed to a distance that ''can'' be imagined, although planets themselves will be much closer to their actual size. Some of the more prominent worldhoppers in the cosmere are:

[[folder:Web Originals]]

* Website/TheCrewOfTheCopperColoredCupids' members are based in a dimension all of their own (known only as the Cupid Homeworld) created when they outgrew their Creator's garage and, in retaliation, told physical reality to bugger off. Hence, all their forays into other universe are examples of dimension-traveling. There is a universe (LikeRealityUnlessOtherwiseNoted) which they designate as “Prime” and have as their main target, presumably because it's where the aforementioned Creator's garage was located, but they have been shown to invade many other, weirder worlds as well.

* ''WesternAnimation/DrDimensionPants'': This is the primary superpower of the titular hero Dr. Dimensionpants, as well as other interdimensional superheroes.

* In the ''Franchise/{{Transformers}}'' franchise, many of the "multiversal singularities" are mentioned as having this ability -- particularly [[ComicBook/TheTransformersMarvel The]] [[ComicBook/TransformersTheWarWithin Fallen]], [[Anime/TransformersCybertron Vector Prime]], [[Franchise/TransformersGeneration1 Unicron]], and [[Franchise/TransformersTimelines Nexus Prime]], as well as the non-singularity [[Anime/TransformersArmada Sideways]]. There's also the city of [[ComicBook/TransformersTransTech Axiom Nexus]], which is roughly analogous to ''TabletopGame/{{Planescape}}'''s Sigil mentioned above, and where the inhabitants all have travelling between dimensions down to a literal science. It's also where lost dimension travelers end up... and often don't get to leave.

* Funny Valentine from ''Manga/JoJosBizarreAdventureSteelBallRun'' has a Stand named "Dirty Deeds Done Dirt Cheap" that allow him to jump across dimensions.

* The [[TheArchmage Wizard Marshall]] Zelretch in the Franchise/{{Nasuverse}} is the only known being to freely travel between alternate realities, by the virtue of having mastered the Second True Magic.

* At the end of ''Anime/SpacePatrolLuluco'' [[spoiler: Luluco is revealed to be Miss Trigger (the mascot of Creator/StudioTrigger) who can traverse and patrol the various dimensions of the various Trigger series.]]
* The main plot of ''Manga/TsubasaReservoirChronicle'' shows Syaoran and his four companions traveling around the multiverse to look for the feathers containing the memories of his beloved Princess Sakura. They traveled through the means of a white rabbit-like creature called Mokona Modoki, who is created by the Dimensional Witch, Yuuko Ichihara, one of the protagonists of ''Manga/{{xxxHolic}}''.
* ''Anime/DreamDimensionHunterFandora'': Yog Sothoth is a dimension-traveling criminal who desires absolute godhood.
* ''Manga/FairyTail100YearsQuest'':
** It's revealed that [[spoiler:Touka and Faris]] are in fact inhabitants of Elentir, another AlternateUniverse to Earth-land in the same vein as the already-revealed Edolas. [[spoiler:This explains why Carla notes Touka, despite being a fellow [[CatsAreMagic Exceed]], was never once mentioned by her mother as existing.]] Although technically only the former naturally possesses this dimension-crossing magic, while the latter is only able to do so [[spoiler:while performing a FusionDance with Touka and having been connected with her long enough to still have access to the spell after their separation]].
** The Moon Dragon God Selene is revealed by [[spoiler:Mystogan]] to possess the power to freely move between dimensions. In fact, [[spoiler:he reveals she's the reason Edolas chose to target Earth-land to steal magic from rather than Elentir, as Selene considers Elentir her proper home and would have launched retaliation against them. And since Selene is a dragon with power on par with [[WorldsStrongestMan Acnologia]], that was a wise choice.]]
* ''Anime/TheUltraman'' has a monster called Zaanmoth who can travel between dimensions, but unintentionally got itself stuck on earth. By the episode's conclusion Ultraman Joneus sends it back to it's dimension, rather than killing it.

** Yuzu's [[MagicalAccessory bracelet]] can teleport Yuya's {{Identical Stranger}}s to different locations if two or more of them are near her, which includes different dimensions. For example she accidentally drags herself and Yugo to the Synchro Dimension because he was holding her while Yuya approached their location.

[[folder:Card Games]]
* ''TabletopGame/MagicTheGathering''. Players are [[https://mtg.gamepedia.com/Planeswalker planeswalkers,]] a denizen of the multiverse RandomlyGifted with a Spark of power that allows them to travel to other planes of existence. The card game represents a duel between two planeswalkers, using their arsenal of spells and creatures collected across the planes to fight again. Prior to the mending, the Spark also granted potent shapeshifting powers ([[ShapeshiftingHealsWounds which made them immortal and difficult to harm]]) and the ability to easily draw large amounts of {{mana}} from the planes they visited; the combination of the two made them [[PhysicalGod like gods]]. Post-mending, it grants a much smaller magical power boost, and even the main ability has been downgraded such that planeswalkers are no longer able to take other people with them to other planes.
* In the ''TabletopGame/YuGiOh'' card game, this is the premise of the [[ExactlyWhatItSaysOnTheTin D. D. (Different Dimension)]] cards. Also, while not part of the D. D. set, Neo the Magic Swordsman's card text describes him as a dimensional drifter.
[[/folder]]

* ''ComicBook/{{Perky}}'' is an involuntary example- he was sent to the Land of Lug through a [[MagiciansAreWizards magical]] DisappearingBox, and whenever the amateur magician pulls the lever on the box, Perky is sent to a new fantasy realm. [[AngstWhatAngst Oddly, he doesn't seem very perturbed by this situation.]]
* In ''ComicBook/XMan'', Nate Grey develops this ability as an extension of his colossal PsychicPowers following his development as part of the [[ComicBook/XManCounterX Shaman Reboot]], whereupon he treated the Multiverse as his personal stepladder.
* Marvel's ''ComicBook/{{Exiles}}'' are teams of people displaced from their home realities tasked to resolve problems in the multiverse on parallel earths under the instruction that it'll save it from collapse. Among them Blink [[BreakoutCharacter stands out by popular demand]] and multiple times is appointed champion and leader of these teams.
* ComicBook/AmericaChavez, of the ComicBook/YoungAvengers and later Ultimates, can open portals to other dimensions by ''punching'' (or sometimes kicking). She's been dimension-hopping for most of her life, solving problems big and small throughout the multiverse.
* ComicBook/TheInhumans, Lockjaw is able to teleport to other dimensions with his teleportation powers, and is even capable of teleporting people to the Negative Zone.
* All the Spiders are able to do this in ''ComicBook/SpiderVerse''. Naturally, the Inheritors, too. A [[ComicBook/WebWarriors task force]] is made after the event to continue doing dimensional monitoring, particularly for worlds that lost their Spiders during the event.
** [[ComicBook/SpiderGwen Gwen Stacy of Earth-65]], who was also part of this task force for a while, occasionally has her own personal dimension-jumping adventures. After ''ComicBook/SpiderGeddon'', she begins using it on a daily basis due to deciding to attend college in the main Marvel universe, as she craved the anonymity she lost at the end of ''Radioactive Spider-Girl''.
* The ''ComicBook/InvaderZimOni'' comics do something like this with [[FourthWallObserver Recap Kid]]. While normally [[AmbiguousGender they]] exist in a blank space outside of the main comic universe, they do occasionally actually directly interact with the setting. And then there's the matter of Issue #40, the FramingDevice of which is Recap Kid accidentally falling into the space between universes and trying to find their way back to the comic universe.
* ''ComicBook/FutureFoundation'''s entire premise is the crew traveling the Multiverse to repair the Molecule Man. When they encounter Rikki, herself a Dimensional Traveler, she checks to see what universe they're from by asking Julie a detail so stupidly unique to their own universe (the existence of the Spider-Mobile), it could verify she was in the right one.
* ''ComicBook/{{Superman}}'': Before the ''[[ComicBook/CrisisOnInfiniteEarths Crisis]]'', Superman, ComicBook/{{Supergirl}} and, by extension, any Kryptonian, were able to travel to other dimensions by their own power, although it was explicitly rather difficult. When Creator/ElliotSMaggin's character [[Characters/SupermanSupportingCast Superwoman]] debuted, it was made clear that one thing that distinguished her from Superman was that she could do it easily.
* In Pre-Crisis days, the ComicBook/LegionOfSuperHeroes' Phantom Girl hailed not merely from another planet, but from a planet called Bgztl occupying the same space as Earth in a parallel universe. Her walking-through-walls power derived from her ability to travel from one universe to the other effortlessly.

* ''[[http://alaxr274.deviantart.com/gallery/33810717 Super Milestone Wars]]'' and its sequel, ''[[http://alaxr274.deviantart.com/gallery/36864527 Super Milestone Wars 2]]'' has this as a major plot point.
* In the ''Literature/{{Discworld}}'' and ''Series/TheBigBangTheory'' crossover ''Fanfic/TheManyWorldsInterpretation'', by Creator/AAPessimal, Ponder Stibbons and Johanna Smith-Rhodes arrive in Pasadena as dimensional travellers, facilitated by supercomputer HEX. Sheldon Cooper, Leonard Hofstadter and the gang get to go on reciprocal visits to Ankh-Morpork. Penny gets an unplanned and scary trip into Earth space because Sheldon could not resist fiddling with the Travelling Engine's controls. HilarityEnsues.

* Delilah from ''Fanfic/TheLegendOfSpyroANewDawn'' is a [[AsianFoxSpirit Kitsune]] capable of traveling through dimensions. This apparently a species trait of her specific type of Kitsune, as it's the only way to leave the Spirit World. After [[Really700YearsOld 200 years]] of traveling the multiverse, she's a {{Cloudcuckoolander}} who's SeenItAll. She often drops {{Shout Out}}s to other series which she's visited, most commonly ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' because she really likes that universe and is best friends with Pinkie Pie. She also mentions the [[NoodleIncident "Cupcakes Incident"]] frequently, which involved a nasty encounter with ''Fanfic/{{Cupcakes|SergeantSprinkles}}''!Pinkie Pie and resulted in her [[WhyDidItHaveToBeSnakes being deathly afraid of cupcakes.]]

* ''Fanfic/TheInfiniteLoops'' will sometimes implement this, having Loopers loop into other settings or even a variant of their own setting. This isn't controlled, and the looper will remain in that setting for the duration of the loop. There are also Traveling Loopers, whose "Home Reality indicator" was damaged to the point where they spend more time in other Loops than in their own.
* ''Fanfic/YuYuGiDigiMoon'' and ''FanFic/DigimonFusionKai'' has Karin Osaka/Sailor Sedna, a native of the Digimon Fusion Kai dimension before she suddenly died and that her spirit is summoned to the nexus by [[Main/GuardianOfTheMultiverse Sailor Cosmos]] to become this role once brought back to life. Since then, she mainly settles in the YYGDM dimension in enforcing her role as a Senshi.
* ''Fanfic/ProjectBluefield'' features the Zeros, who travel to different worlds to A.) record their stories, and B.) hunt down the [[OutsideContextProblem invasive monsters that threaten them.]]
* Technically all the characters in the MagicalGirl CrisisCrossover ''FanFic/ShatteredSkiesTheMorningLights'', brought from their own universes (i.e., separate franchise: ''Franchise/SailorMoon'', ''Manga/CardcaptorSakura'', the first ten ''Anime/PrettyCure'' continuities, ''Franchise/LyricalNanoha'', and ''Franchise/MadokaMagica'') to an InnBetweenTheWorlds in a PlaceBeyondTime to keep them safe from an [[ApocalypseHow/ClassZ Omniversal Metaphysical Negation]]. The best example would be [[MysteriousWaif the Stranger]], an embodiment of people erased from normal space and time, who travels between the universes at will to rescue the survivors.
* ''Fanfic/ThePiecesLieWhereTheyFell'': [[AllThereInTheManual According to his author-given backstory]], Reel (AKA Kamen Rider Skull II) gained the ability to travel around alternate worlds from a meeting with Kamen Rider Decade, though he can only visit A.R. versions of existing stories rather than the core world (which is why he only appears in omakes). He's visited three different versions of the Pieces-verse so far.
* ''Fanfic/CloudedHorizons'': Several of the main characters are Planeswalkers, granted the power to cross planes and dimensions of existence along with other secondary powers by various patrons.
* ''Fanfic/HellsisterTrilogy'': During "The Apokolips Agenda", ComicBook/{{Supergirl}} travels back and forth between dimensions, recruiting other heroes and fighting Darkseid's forces. During the prior arc she also travelled to the antimatter universe through a space warp.
* In ''Fanfic/TheCountsWorld'', most of the characters are dimensional travellers thanks to the Exor Rift, an invisible hole in space located in Bowser's keep and created when Exor came crashing down. It basically allows anyone to travel between almost every other dimension, though Dimentio can only speculate on the rules it operates on.

* In crossover ''Fanfic/CrosswindsOfFate'', The ''[[VisualNovel/FateStayNight Fate]]'' cast travels to the ''Literature/HarryPotter'' universe by means of the Second Magic.
* Downplayed in ''Fanfic/TalesOfTheOtherverse'', where Access can "only" travel freely between the [[Franchise/TheDCU DC]], [[Franchise/MarvelUniverse Marvel]] and [[ComicBook/AmalgamUniverse Amalgam]] universes. Later, the main characters constantly travel between parallel Earths.
* ''Fanfic/QuietAndTheDimensionalTravelerTimelineA'' , a titular dimensional traveler is one of the protagonists of the fanfic.
* ''Fanfic/ThereWasOnceAnAvengerFromKrypton'':
** As revealed in Chapter 34 of ''The Girl Who Could Knock Out the Hulk'', [[spoiler: Kara was pulled out of Earth-16 and into the Kryptonverse because Doom and Reed couldn't properly CosmicRetcon her into having always existed]].
** Jane Shepard is aware that she's from a different universe from the one she woke up to find herself in. [[spoiler: Again, this is due to Doom and Reed being unable to properly merge her, in this case, because Kara interrupted the process.]]

* The ''WesternAnimation/PhineasAndFerb'' [[TheMovie made-for-TV film]] ''WesternAnimation/PhineasAndFerbTheMovieAcrossThe2ndDimension'' is all about this.
* The plot for ''WesternAnimation/SpiderManIntoTheSpiderVerse'' is kicked off by an InterdimensionalTravelDevice going haywire and dragging a number of Spider-Heroes into [[Characters/MarvelComicsMilesMorales Miles Morales]]'s universe.

* Gozer the {{Jerkass God|s}} from ''Franchise/{{Ghostbusters}}'' who enter dimensions to destroy them. One of its nicknames is even "The Traveler".

* Franchise/MarvelCinematicUniverse:
** In ''Film/SpiderManFarFromHome'', Quentin "Mysterio" Beck explains that [[Film/AvengersInfinityWar Thanos' use of the Infinity Stones]] has connected TheMultiverse. His world, Earth-833, was destroyed by monsters called the Elementals, but he was able to cross over to the main MCU setting, Earth-616, to make sure the same doesn't happen to that Earth. [[spoiler:It's a lie, part of Beck's plan to use EngineeredHeroics to become the next superhero. [[RightForTheWrongReasons Ironically, there]] ''[[RightForTheWrongReasons is]]'' [[RightForTheWrongReasons a Multiverse in this setting,]] Beck just had no way of knowing that.]]
** ''Film/DoctorStrangeInTheMultiverseOfMadness'': America Chavez has the ability to create star-shaped portals that lead to other universes. She has no idea how to control her powers, activating them whenever she's afraid. At the start of the film, she'd been to 72 other universes by her count. [[spoiler:Wanda Maximoff]] wants to kill America and steal her powers so she can [[spoiler:find and live in a universe where the ideal life she created in ''Series/WandaVision'' is real]]. Also, a spell in the [[TomeOfEldritchLore Darkhold]] allows the caster to "dreamwalk", which lets them cross dimensions via a GrandTheftMe on their alternate counterpart.
* In ''Film/VenomLetThereBeCarnage'', in the mid-credits scene, Eddie Brock somehow gets transported from a slummy shack to a similarly shaped but much cleaner and fancier hotel room. Before he and Venom have much time to wonder what just happened, [[spoiler:they see on TV is a broadcast of J. Jonah Jameson from the Franchise/MarvelCinematicUniverse telling the public that Spider-Man is Peter Parker in the same scene from ''Film/SpiderManFarFromHome''.]] This was a tie-in for ''Film/SpiderManNoWayHome'', [[spoiler:although humourously Eddie only appears in TheStinger of that film, having spent his entire time in the MCU drinking at a bar.]]

* Creator/RobertAHeinlein:
** ''Literature/GloryRoad''. Anyone who understands the metaphysical geometry involved can pass through the Gates and explore the Twenty Universes, and many do so on a regular basis.
** ''Literature/TheNumberOfTheBeast''. The protagonists use a dimension-hopping device to explore a series of very odd dimensions, including some based on Earth literature.
* Creator/KeithLaumer's ''Literature/LafayetteOLeary'' novels. The protagonist has the ability to travel to feudal/magical alternate Earths.
* In the ''Literature/MythAdventures'' series, the term "Demon" is short for "dimensional traveler". It's not something done casually by the inexperienced; Aahz ([[RunningGag no relation]]) flat refuses to teach Skeeve due to Aahz's powers being dampened for a century due to what Garkin did.
* Creator/PhilipJoseFarmer's ''Literature/WorldOfTiers'' series. Paul Janus Finnegan (AKA Kikaha the Trickster) and Robert Wolff spend much of the novels traveling through artificially created universes.
* In ''Literature/TheChroniclesOfAmber'' series, the Royal Family of Amber and the Lords of Chaos are either this or powerful {{Reality Warper}}s who create new dimensions as they travel, depending on which character's exposition you believe.
* The characters in Creator/{{Piers Anthony}}'s ''Virtual Mode'' series were able to travel through the dimensions along a path from Point A to Point B.
** The method used was, essentially, LostTechnology left in one of the dimensions; one application built a "virtual dimension" made up of 10-foot sections (that, for some reason, mapped out to the Earth's surface)- each section was slightly different from its 'neighbors' based on its own history, but you could walk around the Earth this way, and only be in "yours" when you returned to your starting point.
* ''Literature/JourneyToChaos'': Tasio the Trickster can jump from World Fruit to World Fruit without a care. He drags Eric to Tariatla at the start of ''A Mage's Power'', [[spoiler: sends him back at the end, and then returns him to Tariatla at the start of ''Looming Shadow''.]]
* ''Literature/TheCosmere'' has worldhoppers, people who travel between cosmere's various worlds. Note that despite their differences the worlds are physical planets that exist in the same universe, meaning physical travel between them is possible, but would require FasterThanLightTravel to accomplish. Instead worldhopping is done by traveling through another dimension called the [[MentalWorld Cognitive Realm]]. Since the Cognitive Realm is shaped by human perception, the incomprehensible distances between planets are compressed to a distance that ''can'' be imagined, although planets themselves will be much closer to their actual size. Some of the more prominent worldhoppers in the cosmere are:

** The Ghostbloods, an organization that are currently mostly active on [[Literature/TheStormlightArchive Roshar]], but have a trophy room filled with artifacts from all over the cosmere, and whose leader is [[spoiler:[[Literature/{{Mistborn}} Kelsier]]]].

* In Creator/TerryPratchett and Creator/StephenBaxter's Literature/TheLongEarth series almost everyone on the planet gains the ability to "step" along a chain of alternate Earths thanks to Stepper boxes. Some people are able to naturally step without a box, and some of those are able to sense "soft places" which allow them to step much further down the chain of Earths than just one at a time.
** Humans aren't the only ones either. There is a whole ecology of dimension-hopping creatures that can naturally Step, from "Trolls" and "Elves" to [[FloatingIsland vast gestalt organisms.]]
** It later transpires that the Long Earth [[spoiler: is a consequence of sapient life developing and quantum nonsense. Not only does every planet that could possibly develop such life allow Stepping, each of those parallel worlds is completely disconnected from the universe you accessed the planet from.]] So not only does Earth have it's own chain of parallel worlds, so does Mars... and the parallel Marses don't line up with the parallel Earths. The implications on the vastness of the multiverse are obvious.
* ''Literature/{{Worm}}'':
** The Doormaker can open "doors" between universes. So can [[spoiler:Elle/Labyrinth]], albeit with much more difficulty.
** [[spoiler:Scion and his kind]] walk between universes as easily as a normal might cross a room, and Eidolon shows this ability too when they fight.
* From Literature/TheWitcher, we have Cirilla "Ciri" Fiona Elen Riannon, daughter of the Emperor of Nilfgaard. She has a power the Unicorns refer to as "The Gate of Worlds", which allows her to travel to other universes. [[spoiler:She ends up riding off with Galahad and joining the court of King Arthur in ''Lady of the Lake''.]]
* ''Literature/ShadesOfMagic'': Since the doors between the [[AlternateUniverse four Londons]] were closed, the only people capable of traveling between worlds are the "Antari", those born with a unique link to Magic itself. By the time of the first book, Antari have become [[TheMagicGoesAway so rare]] that the protagonist is one of only two known ones.

* The Necromancer is stated to be one, by some of the gods of ''Literature/{{Dragaera}}''; she apparently considers death to be an aspect of this, since it's moving from one realm or state of living to another.[[note]]She's also stated to consider death "a matter of engineering"; the main character becomes wary of any plan where that's one of the default assumptions.[[/note]] And it turns out (especially in ''Vallista'') that The Paths of the Dead, along with the Halls of Judgement, is something of a nexus that allows people (but usualy gods, demons, or powerful sorcerers that know what they're doing) to travel between different dimensions and worlds.

* ''Series/KamenRiderDecade'' has this as a major plot point. The previous seasons are revealed as [[AlternateUniverse parallel worlds]] that are merging into one, thus leading everyone of them to destruction, so it's up to the titular hero to journey to each one and [[spoiler:destroy them]]. He even arrived in the World Of [[Series/SamuraiSentaiShinkenger Shinkenger]] on one occasion. The reason being Decade normally travels to Rider Worlds, and there aren't any Kamen Riders normally in that world until Diend went there, implying there's even more universes than just the Rider Worlds, but only the Rider Worlds are at risk.
* ''Series/{{Sliders}}'' is a series based on this trope, although in the beginning the characters were travelling uncontrollably.
* ''Series/DoctorWho'' has had its fair share of ParallelUniverse stories, although the Time Lords usually keep a tight leash on that sort of thing. The Doctor's TARDIS is capable of traveling to other universes, but is put at great risk for every moment it stays in one, as she's normally keyed into the spacetime continuum of the regular universe, and is thus one power source short when she's cut off from it.

* Ace Rimmer in ''Series/RedDwarf'' -- by the time of series VII he has become a James-Bond-esque dimension-jumping superhero.
* ''Series/TheManInTheHighCastle'': [[spoiler: Kotomichi, Tagomi, and most likely The Man in the High Castle]] have all figured out how to pull this off and go into alternate timelines, but exactly how it works is a mystery.

* ''Franchise/UltraSeries'': Throughout the franchise many of the Ultras and their foes end up capable of jumping dimensions through different methods. This increased once it was made clear that the franchise's many instalments are all canon within the multiverse, leading to crossovers involving characters travelling from one world to another.

* [[HotWitch Tessa]] from ''VideoGame/RedEarth'' is a [[InsistentTerminology sorcerologist]] (one who employs magic in everyday studies to discern the properties of the universe; she's more or less a witch, though). Her [[EncyclopaedicKnowledge knowledge on a wide variety of subject matter]] in both her home series and various {{crossover}}s imply that she frequently treks across the multiverse to broaden her horizons and learn as much as she possibly can.
* In ''VideoGame/{{Darkstalkers}}'', the only thing linking the Human World and Makai ([[OurMonstersAreDifferent the]] [[OurDemonsAreDifferent Demon]] [[FantasyKitchenSink World]]) is a portal located roughly in the middle of Makai, known as The Gate. Morrigan is a special case, in that she can freely travel between the realms independently of this gateway. Being a [[RebelliousPrincess fun]]-[[BloodKnight loving]] [[SuccubiAndIncubi succubus]], you should be able to understand ''why'' she enjoys this unique ability of hers.
* This is the reason why [[VideoGame/FinalFantasyV Gilgamesh]] in ''Franchise/FinalFantasy'' is heavily implied to be the only recurring character in the series to be the same exact character in most, if not ''all'' appearances. After being thrown into the Interdimensional Rift by his boss Exdeath [[YouHaveFailedMe for his repeated losses against the party]] and [[HeroicSacrifice sacrificing himself to defeat Necrophobe]], Gilgamesh simply [[WalkingTheEarth walks the multiverse]] via the Void and the worlds connected to it. This is even how he stumbles into the conflict of the gods in ''[[VideoGame/DissidiaFinalFantasy Dissidia 012: Final Fantasy]]''; when defeated, [[spoiler:a portal leading to the Rift/Void engulfs him, as Gilgamesh, while subject to the war's rules, has no original world to return to]].
* ''Franchise/TheElderScrolls''
** ''VideoGame/TheElderScrollsIIIMorrowind'':
*** Divayth Fyr is one. According to the in game book ''[[http://www.uesp.net/wiki/Lore:The_Doors_of_Oblivion The Doors of Oblivion]]'', Fyr is one of the few "[[WizardsLiveLonger mortals]]" who can freely travel between the realms of the [[OurGodsAreDifferent Daedra]].
*** Yagrum Bagarn, [[spoiler:the [[LastOfHisKind last living]] [[OurDwarvesAreDifferent Dwemer]]]], was another. He was in an undescribed "outer realm" when the calamity that caused his people to vanish took place. He returned to find them gone, caught the [[BodyHorror Corprus Disease]] soon after, and ended up in Divayth Fyr's Corprusarium where he has been ever since.
** The spin-off DungeonCrawling game ''[[VideoGame/AnElderScrollsLegendBattlespire Battlespire]]'' has the PlayerCharacter become one. He/She travels through many realms of Oblivion in order to defeat the Daedric forces including the Soul Cairn, Shade Perilous, the Chimera of Desolation, and the Havok Wellhead. Even the [[WizardingSchool Battlespire]] itself exists in the "Slipstream", a realm at the edge of Oblivion between it and Mundus.

* Certain characters throughout ''VideoGame/SuperRobotWars'' and its {{Spin Off}}s are, in fact, the same entity throughout their multiple appearances in various installments, the likes of which includes Fighter Roar (later known as "Warrior Roar", to differentiate between himself and [[LegacyCharacter another character who takes on his mantle]]), Dark Brain, [[spoiler:Gilliam Yeager and Cobray Gordon]].
** Due to the events of ''VideoGame/ProjectXZone'', both [[VideoGame/EndlessFrontier Haken Browning]] and [[Characters/SuperRobotWarsAlphaGaiden Sanger Zonvolt]] become this trope. It also applies to a lesser extent to Ryusei, Kyosuke, and Masaki in ''VideoGame/AnotherCenturysEpisode R''.

** Yeesha can Link at will because she's [[MessianicArchetype the Grower]]. In ''VideoGame/UruAgesBeyondMyst'' she gives willing explorers special books that link to a world called Relto and that link with their users; as such, explorers can link to Relto at any time.

* ''VideoGame/TotalDistortion'' has mysterious teleporters that arrived on Earth from nowhere, which turn out to allow travel between millions of different dimensional planes. Earth initially uses this to [[MundaneUtility transport data and freight around the world]], since human travel has the catch of having to endure a 6-week coma when teleported. NASA eventually sets up a team of "dimensionauts" to explore these planes, and you voluntarily have yourself and your [[PlayerHeadquarters Personal Media Tower]] teleported to a Grunge Rock dimension at the cost of ''three million dollars'', in order to make music videos and sell them for enough money to get back home.

* ''VideoGame/SuperRobotWarsV'': [[Anime/Gundam00AWakeningOfTheTrailblazer Setsuna and Tieria]] on accident, when the [=Qan[T]'s=] Quantum System brings them both into the NCC for reasons unknown. Later on, everybody becomes one once they've found out that by combining both Boson Jumping with Ange's Ariel Mode, they can travel wherever they need to be.
* ''Franchise/{{Pokemon}}'': The Legendary Pokémon Solgaleo, Lunala and Necrozma have this ability.
** In ''Videogame/PokemonUltraSunAndUltraMoon'', [[spoiler:Giovanni]] somehow manages to acquire this ability and uses it to [[spoiler:recruit alternate universe versions of villains who succeeded in their plots to form [[LegionOfDoom Team Rainbow Rocket]]]].
* ''VideoGame/{{Putrefaction}}'' ends with you entering a portal leading to another dimension, and the sequel begins with you emerging into it. The game even calls you "Void Walker" because of that.
* ''VideoGame/TheKingOfFighters XIV'' reveals that Nakoruru from ''VideoGame/SamuraiShodown'' gained this ability after becoming a NatureSpirit. This allows her to not only enter the King of Fighters universe to investigate the crack in time and space caused by the events of the previous game, but also recruit the other members of the Another World team even though they came from different universes.
* ''VideoGame/TheWitcher3WildHunt'' introduces Ciri to the video game continuity. Like in the books, she has the ability to travel between universes, and is sought after by the eponymous Wild Hunt for this ability. It's implied that she's visited the world of ''VideoGame/Cyberpunk2077'', another Creator/CDProjektRed game. [[spoiler:One main quest in the game takes Geralt through a few worlds himself, including one that serves as a ShoutOut to ''Literature/{{Solaris}}'', another major piece of Polish literature.]]

* ''VideoGame/FateGrandOrder'': In extremely rare cases, a person is able to travel among various alternate timelines.
** The ''Anime/FatePrototype'' version of Myth/KingArthur has been sent by Myth/{{Merlin}} to travel through the timelines in order to hunt down [[BeastOfTheApocalypse Beast VI]], which keeps [[NighInvulnerable not dying when it's killed]] and Arthur wants to stop it from ever fully manifesting in any timeline.
** A female version of UsefulNotes/MiyamotoMusashi is also shown travelling randomly between timelines, though how she's doing this is unknown even to herself. When recruited, she attributes it to unknowingly consuming rice from a Holy Grail she was using as a bowl. [[spoiler:Her material book profile reveals that she hails from a dead timeline and miraculously managed to escape its destruction, at the cost of being unable to find her way to a CloseEnoughTimeline.]]
** The main antagonist of the pseudo-singularity Shimousa is [[spoiler:Avenger UsefulNotes/AmakusaShiro]], explicitly referred to as an AlternateSelf to the one summonable by Chaldea, who like [[spoiler:Musashi hails from a dead timeline and has been traveling randomly between other timelines.]] Unlike Arthur or Musashi, however, it's indicated he's been doing this ''much'' longer and has ultimately been driven insane and evil by what happened to him before and during his travels. [[spoiler:Eventually, he met an [[EldritchAbomination Foreign God]] he calls "Lucifer" and signed up for a scheme that would allow him to take revenge on the Tokugawa and all of humanity in every timeline for what happened to the Christians at Shimabara.]]
** [[Franchise/CthulhuMythos Randolph Carter]] under the sobriquet of "the Dimension-travelling Gentleman" appears [[spoiler:to help quell a Yog-Sothoth infused Abigail Williams, and departs with her to dimensions unknown to tutor her.]] Unlike the other three, there is no given reason for his ability, though a familiarity with his source material should provide a reasonable pretext.
** ''Literature/SherlockHolmes'' inexplicably has the ability to travel between temporal dimensional aberrations in human history known as Singularities, despite timeline hopping being something only a very select few can do and suddenly loses the ability when he joins the protagonists as their new technical advisor. [[spoiler:It's later revealed this ability is unique to the non-playable iteration of Holmes because he was summoned by the same [[BigBad Foreign God]] that was Amakusa's patron as one of her Disciples. He deliberately sealed his memories and did not use the ability to travel after a few select times so he would not serve as a ManchurianAgent in her grand scheme.]]
* ''VisualNovel/UminekoWhenTheyCry'': the Voyager Witches, most notably Bernkastel and Lambdadelta, are able to traverse the Sea of Fragments to different timelines and universes.
* ''VideoGame/FinalFantasyXIV'': The Shadowbringers expansion has [[spoiler: the Crystal Exarch, who managed to do this by combining the [[{{Precursors}} Allagan Empire's]] Crystal Tower technology with technology reverse-engineered from [[TimeMaster Alexander]] and [[SpaceMaster Omega]] to traverse to the First Shard]]. The Ascians have been able to do it from the beginning, and after being pulled over the first time the Warrior of Light gains the ability to pass between the First Shard and the Source at will.
* ''Franchise/{{Neptunia}}'': Several characters have the power to traverse dimensions at will and send people through them.
** In ''VideoGame/HyperdimensionNeptuniaVictory'', Croire and [[spoiler:Rei Ryghts in her CPU form]] have this ability. [[spoiler:The Reis from Hyperdimension and Ultradimension weaponized this to give each other power boosts by drawing upon power from ''two'' separate worlds.]]
** In ''VideoGame/MegadimensionNeptuniaVII'', Croire appears again alongside Older Neptune, who [[spoiler:is the Neptune from the Ultradimension]] and has been using Croire to hope dimensions. The BigBad [[spoiler:Kurome/the original Uzume]] also has this ability, though initially she could only cross dimensions as a spirit and needs a power boost to pull off the proper crossing she wants [[spoiler:in order to launch a monster invasion from the Zero and Heartdimensions to destroy Hyperdimension]], which she obtains thanks to [[spoiler:absorbing Rei's remaining power kept by Croire as well as stealing power from the [=CPUs=]]].
* ''[[VideoGame/DontEscape Don't Escape: 4 Days To Survive]]'': [[spoiler:Sidereal Plexus is an entire company of such travelers. Their main employees travel through [[VideoGame/DeepSleepTrilogy the Realm of Dreams]] to other universes and spread their technologies while attempting to synthesize the energy crystals their sleeper pods require to function]]. Additionally, [[spoiler:the surviving members of the party become this at the end of a successful playthrough, though unless all four are present and both disks have been collected, they wind up in another universe that undergoes a similar apocalypse]].

[[folder:Web Comics]]

* WebOriginal/JennyEverywhere has the power to travel between alternate realities (and shift objects between universes, and mentally link up with alternate versions of herself) in most of her implementations, giving her the title "The Shifter".
* Treated rather literally in ''Webcomic/{{Immaterial}}'', where the parallel dimension seems to actually be another geometrical dimension. Grimnir travels between the two for his job, and the protagonists - Alex and Ethan - accidentally tag along.

[[folder:Web Original]]
* Website/TheCrewOfTheCopperColoredCupids' members are based in a dimension all of their own (known only as the Cupid Homeworld) created when they outgrew their Creator's garage and, in retaliation, told physical reality to bugger off. Hence, all their forays into other universe are examples of dimension-traveling. There is a universe (LikeRealityUnlessOtherwiseNoted) which they designate as “Prime” and have as their main target, presumably because it's where the aforementioned Creator's garage was located, but they have been shown to invade many other, weirder worlds as well.
* In ''TabletopGame/NewVindicators'', this shows up a few times:
** First of all, there's the character David Kennel, aka Suicide King, who develops the Neo-Sapien power to alter his dimensions, and eventually to traverse multiple dimensions. Evil ones have showed up, and there may even be a whole group of David Kennel's working together.
** Another example is The Drifter, a Neo-Sapien with a superfast mind who has a device, called The Astrolabe, that lets her travel dimensions.
* The Website/SCPFoundation gives us [[http://www.scp-wiki.net/scp-507 SCP-507.]] It plays with the trope in that 507 is randomly pulled into other dimensions once or twice a month, with no control over when he vanishes, where he goes, or how long he stays there.
* Very common in the various Roleplay/{{Glowfic}}, especially in Effulgence, where Jane makes inter-dimensional travel easy.
* In ''WebVideo/BedtimeStoriesYoutubeChannel'', there's the Man from Taured from the episode of the same name. Unlike most examples, he was an unwitting case, who apparently didn't even realize that he had gone through a different dimension upon landing at Haneda Airport in Japan. He is subsequently detained but mysteriously vanishes only hours later, apparently returning to his own dimension.

* The "[[Recap/FamilyGuyS8E1RoadToTheMultiverse Road to the Multiverse]]" episode of ''WesternAnimation/FamilyGuy'' has Brian and Stewie becoming this.
* In the ''Franchise/{{Transformers}}'' {{multiverse}}, many of the "multiversal singularities" are mentioned as having this ability--particularly [[ComicBook/TheTransformersMarvel The]] [[ComicBook/TransformersTheWarWithin Fallen]], [[Anime/TransformersCybertron Vector Prime]], [[Franchise/TransformersGeneration1 Unicron]], and [[Franchise/TransformersTimelines Nexus Prime]], as well as the non-singularity [[Anime/TransformersArmada Sideways]]. There's also the city of [[ComicBook/TransformersTransTech Axiom Nexus]], which is roughly analogous to ''Planescape's'' Sigil mentioned above, and where the inhabitants all have travelling between dimensions down to a literal science. It's also where lost dimension travelers end up... and often don't get to leave.
* WesternAnimation/RickAndMorty are this as well due to Rick's "Portal Gun." This technology is unique to Rick and his alternate selves, and is one of a number of reasons many aliens in the setting want to capture him.
** In the Pilot episode, the Galactic Federation also seemed to have access to interdimensional travel, as they ran Interdimensional Customs, though this seems to have been retconned, as in future episodes, it's made clear that only Rick and his alternate selves have technology with this capability.
* ''WesternAnimation/DrDimensionPants'': this is the primary superpower of the titular hero Dr. Dimensionpants, as well as other interdimensional superheroes.
* In ''WesternAnimation/GravityFalls,'' this is what happened to [[spoiler:the Author, aka Ford Pines]]: he built a portal to another dimension, he was accidentally pushed in by [[spoiler:his brother Stan]], then spent thirty years wandering around the multiverse before said pusher [[TheAtoner managed to bring him back]]. The show only provides [[NoodleIncident a few hints]] about where he went, with more details appearing in the tie-in book ''Literature/GravityFallsJournal3.''
* In ''WesternAnimation/StarVsTheForcesOfEvil'', many characters do this. The most commonly-seen method is using "dimensional scissors" to cut holes within the fabric of reality, though there are other ways to open such portals, either through other items (like a chainsaw) or some innate teleportation ability. The final season also reveals that [[spoiler:the Magic Realm serves as a hub from which one can travel between dimensions. If you can maintain your mind long enough to travel through it, anyway.]]
* Discord from ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' has the ability to quite easily tear open portals to other universes with his talons. This could very well be an explanation as to why he makes references to other stories, such as “Star Wars” and “Harry Potter”.

* In the ''TabletopGame/YuGiOh'' card game, this is the premise of the [[ExactlyWhatItSaysOnTheTin D. D. (Different Dimension)]] cards. Also, while not part of the D. D. set, Neo the Magic Swordsman is described as a dimensional drifter on his card.

* ''[[VideoGame/DontEscape Don't Escape: 4 Days To Survive]]'': [[spoiler:Sidereal Plexus is an entire company of such travelers. Their main employees travel through [[VideoGame/DeepSleep the Realm of Dreams]] to other universes and spread their technologies while attempting to synthesize the energy crystals their sleeper pods require to function]]. Additionally, [[spoiler:the surviving members of the party become this at the end of a successful playthrough, though unless all four are present and both disks have been collected, they wind up in another universe that undergoes a similar apocalypse]].
