Dimensional Traveler
aka: Dimensional Traveller

Go To

"Gozer, the Gozerian? Good evening! As a duly designated representative of the city, county, and state of New York, I order you to cease any and all supernatural activity and return forthwith to your place of origin, or to the nearest convenient parallel dimension."

A dimensional traveler is any character who can (more or less) freely travel between various planes of existence, like parallel universes, etc. Their ability to travel is usually powered by an Interdimensional Travel Device or some form of Functional Magic, but it can also happen that a character was inherently born with such power.

This is also a common explanation for Crossovers, as occasionally the characters will arrive in the universe of another hero.

A possible practical application of this power is to make use of Extradimensional Shortcuts.

Distinct from Time Travel because, although Time is considered the "fourth dimension", time travellers otherwise remain in the same plane while hopping between its different time periods.

    Anime and Manga 
  • Funny Valentine from Jo Jos Bizarre Adventure Steel Ball Run has a Stand named "Dirty Deeds Done Dirt Cheap" that allow him to jump across dimensions.
  • Various mages in Lyrical Nanoha are shown as capable of teleporting across dimensions, though such spells take quite a bit of time to set-up. For non-mages, the Magitek of The Multiverse has advanced enough to allow for inter-dimensional starships, including commercial ones, for your dimension hopping needs. However, the best examples of dimension travelers in the franchise is the Original Generation characters from Magical Girl Lyrical Nanoha A's Portable : The Gears of Destiny, who in side-materials after the events of the game, had discovered Lost Technology that allows people to be transported across different continuities.
  • Milk Closet is about a group of children randomly afflicted with this, jumping between universes before they're found by a woman who helps them control their powers and bond them to a symbiote. It's a pretty weird series.
  • The Wizard Marshall Zelretch in the Nasuverse is the only known being to freely travel between alternate realities, by the virtue of having mastered the Second True Magic.
  • Hunters in Red Ash: Gearworld regularly go to parallel worlds to hunt for Magicicadas.
  • At the end of Space Patrol Luluco Luluco is revealed to be Miss Trigger (the mascot of Studio TRIGGER) who can traverse and patrol the various dimensions of the various Trigger series.
  • The main plot of Tsubasa -RESERVoir CHRoNiCLE- 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 xxxHolic.
  • Dream Dimension Hunter Fandora: Yog Sothoth is a dimension-traveling criminal who desires absolute godhood.
  • Fairy Tail: 100 Years Quest:
    • It's revealed that Touka and Faris are in fact inhabitants of Elentir, another Alternate Universe to Earth-land in the same vein as the already-revealed Edolas. This explains why Carla notes Touka, despite being a fellow 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 while performing a Fusion Dance 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 Mystogan to possess the power to freely move between dimensions. In fact, 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 Acnologia, that was a wise choice.
  • The☆Ultraman 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.

    Card Games 
  • Magic: The Gathering. Players are planeswalkers, a denizen of the multiverse Randomly Gifted 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 (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 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 Yu-Gi-Oh! card game, this is the premise of the 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.

    Comic Books 
  • In X-Man, Nate Grey develops this ability as an extension of his colossal Psychic Powers following his development as part of the Shaman Reboot, whereupon he treated the Multiverse as his personal stepladder.
  • Marvel's 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 stands out by popular demand and multiple times is appointed champion and leader of these teams.
  • America Chavez, of the Young Avengers 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.
  • All the Spiders are able to do this in Spider-Verse. Naturally, the Inheritors, too. A task force is made after the event to continue doing dimensional monitoring, particularly for worlds that lost their Spiders during the event.
    • 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 Spider-Geddon, 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 Invader Zim (Oni) comics do something like this with Recap Kid. While normally 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 Framing Device of which is Recap Kid accidentally falling into the space between universes and trying to find their way back to the comic universe.
  • Future Foundation'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.
  • Superman: Before the Crisis, Superman, Supergirl and, by extension, any Kryptonian, were able to travel to other dimensions by their own power, although it was explicitly rather difficult. When Elliot S! Maggin's character 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 Legion of Super-Heroes' 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.

  • Robert A. Heinlein:
    • Glory Road. 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.
    • The Number of the Beast. The protagonists use a dimension-hopping device to explore a series of very odd dimensions, including some based on Earth literature.
  • Keith Laumer's Lafayette O'Leary novels. The protagonist has the ability to travel to feudal/magical alternate Earths.
  • In the Myth Adventures series, the term "Demon" is short for "dimensional traveler". It's not something done casually by the inexperienced; Aahz (no relation) flat refuses to teach Skeeve due to Aahz's powers being dampened for a century due to what Garkin did.
  • Philip José Farmer's World of Tiers series. Paul Janus Finnegan (AKA Kikaha the Trickster) and Robert Wolff spend much of the novels traveling through artificially created universes.
  • In The Chronicles of Amber series, the Royal Family of Amber and the Lords of Chaos are either this or powerful Reality Warpers who create new dimensions as they travel, depending on which character's exposition you believe.
  • The characters in 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, Lost Technology 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.
  • Journey to Chaos: 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, sends him back at the end, and then returns him to Tariatla at the start of Looming Shadow.
  • The Cosmere 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 space travel to accomplish. Instead worldhopping is done by traveling through another dimension called the Cognitive Realm. Since the Cognitive Realm is shaped by human perception, the uninhabited lightyears between planets can be traversed easily, although planets themsevles will be much closer to their actual size. Some of the more prominent worldhoppers in the cosmere are:
    • Hoid, an immortal being and Master of Disguise with mysterious agenda. He is by far the most commonly seen worldhopper, appearing in nearly every Cosmere novel, although often in a way that it's not entirely obvious that it's him. He does seem to have taken a special interest in Roshar, and thus has a far larger role there.
    • Khriss, the composer of Ars Arcana, the summaries of magic found in all Cosmere novels, although her in-person appearances are limited outside of White Sand, which takes place before she became a worldhopper.
    • The Seventeenth Shard, an organization striving to maintain an Alien Non-Interference Clause among its fellow worldhoppers.
    • Nightblood somehow travelled from Nalthis to Roshar between the events of Warbreaker and The Stormlight Archive. Zahel's, aka Vasher's, presence probably has something to do with this. Vivenna is also looking for both of them, under the pseudonym Azure.
    • The Ghostbloods, an organization that are currently mostly active on Roshar, but have a trophy room filled with artifacts from all over the cosmere, and whose leader is Kelsier.
    • The Ire, a very old group of Elantrian worldhoppers that have outposts in the cognitive realm on most worlds. They are very secretive, having little contact with other worldhopping groups.
  • In Terry Pratchett and Stephen Baxter's The Long Earth 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 vast gestalt organisms.
    • It later transpires that the Long Earth 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.
  • Worm:
    • The Doormaker can open "doors" between universes. So can Elle/Labyrinth, albeit with much more difficulty.
    • 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 The Witcher, 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. She ends up riding off with Galahad and joining the court of King Arthur in Lady of the Lake.
  • Shades of Magic: Since the doors between the 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 so rare that the protagonist is one of only two known ones.
  • In The Elric Saga, Elric possesses the ability to transport himself between dimensions through his sorcery, and does so on a semiregular basis. Marvel Comics even exploited this ability to justify a crossover with Conan the Barbarian.
  • InCryptid: Alice Price-Healy has been searching for her husband through a dozen other dimensions for decades, and as a result looks younger than her own grandkids.
  • The Necromancer is stated to be one, by some of the gods of 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  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.

    Live-Action TV 
  • Kamen Rider Decade has this as a major plot point. The previous seasons are revealed as 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 destroy them. He even arrived in the World Of 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.
  • Sliders is a series based on this trope, although in the beginning the characters were travelling uncontrollably.
  • Doctor Who has had its fair share of Parallel Universe 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.
  • Once Upon a Time consists of multiple "worlds" that make up the universe; traveling in between them is difficult. The magic used is called World-Crossing or Portal Jumping; spells or magical items like beans or slippers can transport people but voluntarily and regularly travelling between them can only be accomplished by certain individuals.
    • Jefferson aka the Mad Hatter, via his hat. When his hat is taken from him, he grows a little bit mad trying to make one that replicates its abilities.
    • Ariel also seems to possess this ability; it seems to be a general mermaid thing.
    • The White Rabbit of Once Upon a Time in Wonderland can create rabbit-holes that achieve the same effect.
  • Ace Rimmer in Red Dwarf — by the time of series VII he has become a James-Bond-esque dimension-jumping superhero.
  • The Man in the High Castle: 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.
  • Supernatural:
    • The half-human offspring of an Archangel can open doorways to alternate universes. The first time, this happened unwittingly when Lucifer's son wasn't even born yet, but his mere presence tore a hole in the fabric of reality to a realm where the Apocalypse was never stopped.
    • God himself can traverse different universes at will, given that he's the creator of, well, everything. Which takes a more sinister turn when it's revealed that he treats these universes as discarded story drafts.
  • Ultra Series: 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.
    • Ultraseven: The Alien Icarus forces planned to conquer Earth from within the fourth dimension, with one of them trying to get the planet ready for their arrival before it gets defeated by Seven.
    • Ultraman Dyna: Shin Asuka/Dyna is perhaps the most popular example as he found himself travelling the Multiverse after the series finale where he was sucked inside of a wormhole caused by Gransphire's destruction. Ever since Mega Monster Battle: Ultra Galaxy Legends he's found himself often helping out many new Ultras in their exploits. He gets to temporarily go back home in Ultraman Saga.
    • Ultraman Nexus: It's revealed through supplementary material that The Next/Nexus/Noa had been hopping through various universes and dimensions protecting them, such as the M78 Universe.
    • Ultraseven X: As it turns out "Ultraseven X" is actually the original Ultraseven, who ended up following the malevolent Graykess back to their home universe after a failed attempt at taking over Seven's world, but ended up going incognito to uncover their conspiracy.
    • Superior Ultraman 8 Brothers: The original Ultraman Mebius ends up in the universe where the film takes place after being summoned to it by the mystical Girl in Red Shoes.
    • Ultraman Zero: The titular Ultra becomes one himself after Ultraman Zero: The Revenge of Belial being empowered by Ultraman Noa's Shield of Baradhi, which allows him to open wormholes between dimensions at will. He uses it later in Ultraman Saga in order to travel to the world that the film takes place in.
    • Ultraman Trigger: New Generation Tiga: Mr. Shizuma turns out to be this, as he originates from the Neo Frontier Universe, having been a GUTS Officer in that universe before being sucked in by a rogue wormhole in a mission and left stranded on Trigger's Earth where he ultimately settled down since he could no longer go back home. Similar to the aforementioned Shin Asuka.

    Tabletop Games 
  • Dungeons & Dragons
    • Anyone with the Cubic Gate or Amulet of the Planes has the ability to be one.
    • The cosmology supports this trope, as all the various planes are linked by naturally-forming portals and reachable by the use of moderately high-level spells.
    • Planescape: Integral to the setting, where the focus is on the residents of Sigil, an extradimensional city riddled with portals to the entirety of the multiverse, making it the informal trading and information hub of all existence.
    • Advanced Dungeons & Dragons 2nd Edition: The obscure "Dimensionalist" class is a wizard specialized in magics relating to traveling to and manipulating dimensions, such as Thinking Up Portals. It's portrayed as a more specialized subclass of the standard conjurer, whose standard spellset covers a mixture of dimension travel and Summon Magic.
    • In 3E, gem dragons have the innate ability to shift between the Prime Material and Inner Planes, and usually lair in the latter while foraging and defending territories in the former.

    Video Games 
  • Tessa from Red Earth is a sorcerologist (one who employs magic in everyday studies to discern the properties of the universe; she's more or less a witch, though). Her knowledge on a wide variety of subject matter in both her home series and various crossovers imply that she frequently treks across the multiverse to broaden her horizons and learn as much as she possibly can.
  • In Darkstalkers, the only thing linking the Human World and Makai (the Demon 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 fun-loving succubus, you should be able to understand why she enjoys this unique ability of hers.
  • This is the reason why Gilgamesh in Final Fantasy 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 for his repeated losses against the party and sacrificing himself to defeat Necrophobe, Gilgamesh simply 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 Dissidia 012: Final Fantasy; when defeated, 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.
  • The Elder Scrolls
    • The Elder Scrolls III: Morrowind:
      • Divayth Fyr is one. According to the in game book The Doors of Oblivion, Fyr is one of the few "mortals" who can freely travel between the realms of the Daedra.
      • Yagrum Bagarn, the last living 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 Corprus Disease soon after, and ended up in Divayth Fyr's Corprusarium where he has been ever since.
    • The spin-off Dungeon Crawl game Battlespire has the Player Character 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 Battlespire itself exists in the "Slipstream", a realm at the edge of Oblivion between it and Mundus.
  • Avencast: Rise of the Mage has Gorlin, a dimension-hopping vendor who can conveniently show up whenever you need something. Where he goes in the meantime is left unexplored.
  • Certain characters throughout Super Robot Wars and its Spin Offs 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 another character who takes on his mantle), Dark Brain, Gilliam Yeager and Cobray Gordon.
  • The whole plot of BioShock Infinite hinges on the Lutece twins' ability to travel between alternate realities and pulling new, alternate Bookers to Columbia in an attempt to release Elizabeth. Elizabeth herself gains the same powers, but amplified by the end of the game, but loses them again in part two of the Burial at Sea DLC.
  • The Longest Journey:
    • Shifters in series are the only creatures known to physically travel between the twin worlds of Stark and Arcadia, as well as to and from much smaller splinter worlds, like the Guardian's Realm (although speculation abounds that the Draic Kin are capable of it, as well). April Ryan, the protagonist of the first game, and her reincarnation Saga from Dreamfall Chapters are the only known Shifters in the series.
    • The Dreamers like Zoë Castillo and Faith from Dreamfall and Hanna and Lux from Chapters are able to project a physical presence into other worlds without physically leaving their plane of origin, where their bodies remain sleeping while they "travel". As Chapters reveals, though, their true potential is so much greater that using it just to travel across dimensions is like hammering in nails with a microscope.
    • The aforementioned Saga from Chapters may be the ultimate dimension traveler in the series, however, since, in addition to Shifting, she is an expert on the "Songlines", which apparently connect all worlds of the vast multiverse, not limited to just the Twin Worlds of Stark and Arcadia the series takes place in. In the epilogue, she has made a map of them and keeps a bunch of weird, physics-defying mementos from her travels.
  • The D'ni people in the Myst universe travel between realities using Portal Books. They can't take these books with them, so they don't usually qualify for this trope, but there are special cases:
    • Yeesha can Link at will because she's the Grower. In Uru: Ages Beyond Myst 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.
    • The Bahro can link at will, and can also create links for others by various means.
    • Escher, seen in Myst V: End of Ages, can link at will because he wears a Bahro skin.
  • Total Distortion 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 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 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.
  • Super Paper Mario involves Mario, Peach, Bowser, and Luigi, traveling through various dimensions to prevent the end of all existence.
  • Super Robot Wars V: 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.
  • Pokémon: The Legendary Pokémon Solgaleo, Lunala and Necrozma have this ability.
  • The King of Fighters XIV reveals that Nakoruru from Samurai Shodown gained this ability after becoming a Nature Spirit. 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.
  • The Witcher 3: Wild Hunt 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 Cyberpunk 2077, another CD Projekt RED game. One main quest in the game takes Geralt through a few worlds himself, including one that serves as a Shout-Out to Solaris, another major piece of Polish literature.
  • Warframe features Limbo, a warframe whose shtick is travelling in and out of the Rift, a dimension where he can regenerate his mana and be untouchable to enemies he hasn't banished along.
  • Fate/Grand Order: In extremely rare cases, a person is able to travel among various alternate timelines.
    • The Fate/Prototype version of King Arthur has been sent by Merlin to travel through the timelines in order to hunt down Beast VI, which keeps not dying when it's killed and Arthur wants to stop it from ever fully manifesting in any timeline.
    • A female version of Miyamoto Musashi 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. 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 Close-Enough Timeline.
    • The main antagonist of the pseudo-singularity Shimousa is Avenger Amakusa Shiro, explicitly referred to as an Alternate Self to the one summonable by Chaldea, who like 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. Eventually, he met an Alien 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.
    • Randolph Carter under the sobriquet of "the Dimension-travelling Gentleman" appears 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.
  • Umineko: When They Cry: the Voyager Witches, most notably Bernkastel and Lambdadelta, are able to traverse the Sea of Fragments to different timelines and universes.
  • Final Fantasy XIV: The Shadowbringers expansion has the Crystal Exarch, who managed to do this by combining the Allagan Empire's Crystal Tower technology with technology reverse-engineered from Alexander and 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.
  • Neptunia: Several characters have the power to traverse dimensions at will and send people through them.
    • In Hyperdimension Neptunia Victory, Croire and Rei Ryghts in her CPU form have this ability. The Reis from Hyperdimension and Ultradimension weaponized this to give each other power boosts by drawing upon power from two separate worlds.
    • In Megadimension Neptunia VII, Croire appears again alongside Older Neptune, who is the Neptune from the Ultradimension and has been using Croire to hope dimensions. The Big Bad 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 in order to launch a monster invasion from the Zero and Heartdimensions to destroy Hyperdimension, which she obtains thanks to absorbing Rei's remaining power kept by Croire as well as stealing power from the CPUs.
  • Don't Escape: 4 Days To Survive: Sidereal Plexus is an entire company of such travelers. Their main employees travel through 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, 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.

  • Shrapnel: Rifters are people who are able to travel to other dimensions with a piece of equipment called a "dimensional anchor", that can be used to open rifts for inter-dimensional travel.

    Web Comics 

    Web Original 
  • The Crew of the Copper-Colored Cupids' 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 (Like Reality Unless Otherwise Noted) 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 New Vindicators, 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 SCP Foundation gives us 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 Glowfic, especially in Effulgence, where Jane makes inter-dimensional travel easy.
  • In Bedtime Stories (YouTube Channel), 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.

    Western Animation 
  • The "Road to the Multiverse" episode of Family Guy has Brian and Stewie becoming this.
  • In the Transformers multiverse, many of the "multiversal singularities" are mentioned as having this ability—particularly The Fallen, Vector Prime, Unicron, and Nexus Prime, as well as the non-singularity Sideways. There's also the city of 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.
  • Rick and Morty 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.
  • Dr Dimension Pants: this is the primary superpower of the titular hero Dr. Dimensionpants, as well as other interdimensional superheroes.
  • In Gravity Falls, this is what happened to the Author, aka Ford Pines: he built a portal to another dimension, he was accidentally pushed in by his brother Stan, then spent thirty years wandering around the multiverse before said pusher managed to bring him back. The show only provides a few hints about where he went, with more details appearing in the tie-in book Gravity Falls: Journal 3.
  • In Star vs. the Forces of Evil, 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 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 My Little Pony: Friendship Is Magic 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”.
