Dimensional Traveler

aka: Dimensional Traveller
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 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.

See also Planar Champion.


Examples:

Anime and Manga
  • 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 Magi Tech 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 As 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.
  • 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.

Collectible Card Game
  • Magic: The Gathering. Players are planeswalkers, able to travel to other planes of existence. The card game represents a duel between two planeswalkers. The Planeswalker Spark that grants this power used to grant god-like power as well Pre-Mending. Post-Mending, the ability to travel between planes is the only power it grants.
  • 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 Book
  • Nate Grey develops this ability as an extension of his colossal Psychic Powers following his development into a Planar Champion as part of the Shaman Reboot, whereupon he treated the Multiverse as his personal stepladder.
  • America Chavez of the Young Avengers can open portals to other dimensions with her foot, which the group uses as means of transportation in searching for Tommy and Mother.

Fan Works

Film

Literature
  • 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 this.
  • Philip Jose 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.

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.
  • 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.

Tabletop Games

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 III: Morrowind - Divayth Fyr is said to be 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.
  • Mario travels between dimensions to save them all from a multiverse-ending threat in Super Paper Mario. The Big Bad's henchman, Dimentio, has this as a superpower.
  • 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.
  • Shifters in The Longest Journey 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, is the only known Shifter thus far, however. Additionally, Dreamers like Zoe Castillo, the protagonist of Dreamfall, 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".

Web Comics

Web Original
  • 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 pulled into other dimensions at random, with no control over when he vanishes, where he goes, or how long he stays there.
  • 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.

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 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.
