Alternate Self

Go To
Proving once again that teleporters can do truly anything!

TG: and hey you might even be able to help your past dream self wake up sooner without all that fuss you went through
TT: I think the true purpose of this game is to see how many qualifiers we can get to precede the word "self" and still understand what we're talking about. ''
Dave Strider and Rose Lalonde, Homestuck

The Alternate Self is the same person as the character, but living a separate life. The most common cause is that the two alternate selves live in separate timelines that diverged reasonably recently and were the same or very similar during the person's formative years.

However, in some Speculative Fiction, a Alternate Self can also be created by a Teleporter Accident, or even a extreme case of Cloning Blues, where the clone somehow keeps the personality, skills and memories of the original.

The character and the alternate self (or the two alternate selves, if the plot treats them equally as characters) might have been more or less changed by different circumstances, but they are still the same person at the core. They may or may not be the same age, but they do NOT have a linear relationship of one being the younger self that will become the other — the older self.


An Alternate Self is the opposite of a Mirror Self, and yet they often overlap in a fluid pondering of identity.

  • Alternate Self = Same person, but different life.
  • Mirror Self = The opposite person, but in some ways still the same.

In the case of separate timelines, the two alternate selves may or may not be able to share information through Flash Sideways.

When several alternate selves team up against something or someone, it's an Alliance of Alternates. The appearance of an alternate may result in Doppelgänger Gets Same Sentiment. If the alternate self goes by a different name, see Alternative-Self Name-Change.

  • Dragon Ball:
  • In Fate/kaleid liner PRISMA☆ILLYA, there are three separate characters who are parallel versions of one person, Shirou Emiya. First is Illya's older brother, who lives a normal life. Second is Miyu's older brother, whose life follows a parallel version of Fate/stay night. Third is Heroic Spirit EMIYA, who comes from a future where Shirou Emiya contracted with the world and became a Heroic Spirit. The second learns the third's identity when the latter responds to his summoning and lends him his power through the Archer Card.
  • Re:CREATORS: This trope is used to explain what happens when a fictional character comes to life in the real world. According to Meteora, the characters in the real world are merely alternate versions of the original characters, who still exist within their original stories. Even if the characters die in the real world, the original versions will still exist, but they will have no memories or recollection about what happened in the real world; which means that, emotionally and psychologically, they are not the same characters we have come to know across the series.
  • A huge plot point in Yu-Gi-Oh! ARC-V where the protagonist Yuya and deuteragonist Yuzu each have three people that look exactly like them in three separate dimensions.
  • In EDENS ZERO, this is what happens whenever a planet's time gets eaten by a Chronophage, which essentially erases the planet and replaces it with an earlier version of itself, including anyone who was on the planet at the time. Since this isn't really time travel, anyone from the "past" can live an entirely different life from before without setting off any time paradoxes, because the rewind is still a part of history. This allows the "past" and "present" versions of Weisz, one of the main characters, to co-exist because "Present Weisz" managed to escape the planet without being erased.

    Comic Books 
  • City of Dreams: the protagonist is quite different in her dreams compared to her waking world self.
  • DC Comics: Final Crisis: Superman Beyond 3D is essentially a team of Superman counterparts from the 52 Universes. Not all of them are alternate versions of Clark himself (there's a Captain Atom and a Captain Marvel), but most of them are.
  • Marvel's What If? rarely showed alternate selves meeting, but its Spiritual Successor, Exiles, often had such meetings.
  • Supergirl and Power Girl are the exact same person from different universes.
    • Post-Flashpoint Power Girl is very reluctant to meet her mainstream universe self at first partly because she is worried the universe would explode if they actually touched. When they finally meet in Supergirl Volume 6 #19 the universe is fine, the two Karas psychically bond and kick butt together, and the only snag is Supergirl's fortress AI mistaking Power Girl, then Supergirl herself for a clone and trying to destroy her.
    • Supergirl: Cosmic Adventures in the 8th Grade: In the fifth issue Supergirl finds Supragirl, her counterpart from an aborted timeline.
  • The Multiversity, being a multiverse crisis event, features a number of alternate versions of DCU characters, including Earth-4's versions of the Charlton Comics heroes, Earth-5's versions of the Marvel Family, Earth-10's Kal-L, Earth-23's Kalel, etc. Taken to the next level in Thunderworld #1, which sees Sivanas from across the multiverse team up.
  • Convergence features multiple versions of characters from DC's pre-New 52 timelines/universes meeting each other and the people they know.
  • The Spider-Verse event is a team-up of Spider-Man counterparts from across the Marvel multiverse, which continued in Web Warriors and Spider-Geddon.
  • Spider-Gwen (A.K.A. Spider-Woman and Ghost-Spider), herself an alternate spider-powered variation of Gwen Stacy from Earth-65, has had several encounters.
    • She learns about her 616 self during Spider-Verse, because she was confused by Peter's clear discomfort around her.
    • During her first solo series, she encounters that very Gwen. However, due to how time-travel works in the Marvel Universe, this causes a timeline split, with the new Gwen-617 becoming a detective and bonding with a symbiote of her own.
    • During her crossover with Miles Morales, she finds herself on the utopian Earth-8. Turns out that Gwen-8 is married to Miles-8. Oh, and they have kids.
    • She helps kidnap and replace a clone of Gwen-616 during The Clone Conspiracy.
    • Ghost-Spider is kicked off with a quest to help a Gwen who’d turned herself into a heroic Green Goblin but had lost control when she witnessed the death of her father and her Spider-Man, Harry Osborn, sacrificing himself for her.
  • The Secret Wars (2015) miniseries Thors has many different versions of Thor collectively serving as Battleworld's police and a serial murderer killing off versions of Jane Foster and Donald Blake. The whole event is set up so that almost every major character has alternate selves running around except for Doctor Doom and the majority of the Fantastic Four. As in only one Doom, Sue Storm (Mrs. Doom), Johnny Storm (is the "sun"), Ben Grimm (is the "Shield" containing the more lethal territories), Franklin and Valeria... and no Reed Richards at all. Until the survivors arrive including two of him (Mr. Fantastic from the main universe, and the Maker from the Ultimate Marvel one).
  • Averted in Sonic the Hedgehog/Mega Man: Worlds Unite, which features both the main Sonic the Hedgehog (Archie Comics) universe and the Sonic Boom universe, but only Boom characters who do not have counterparts in the main Sonic universe play active roles in the crossover itself. The Boom versions of Orbot and Cubot do make a tiny contribution towards the beginning by building a Genesis Portal for X, Zero, Axl, Sticks, Fastidious, and Comedy, but that's the extent the actual alternate characters are involved, and they do not meet each other at any point.
  • Superboy (1994): The "Hyper-Tension!" arc is kicked off by a version of Kon-El from a different reality showing up with a cryptic warning and dying as the Justice League tries to save him. Kon-El then learns an evil alt-reality version of himself who was completed to Westfield's plans has been traveling through Hypertime taking over different earths and imprisoning the local versions of Superboy including Kal-El (Earth-One), Karkan (Earth-183), Kal-El (Earth-395), Supergrrl (Earth-1098), and Kid Kon-El (Earth-1890) who then all team up with our Superboy to defeat Westfield's evil clone.
  • The Final Days of Superman features three versions of Superman - the New 52 Superman, the pre-New 52 Superman, and an insane Energy Being copy of the New 52 Superman who's convinced he's the real one. It also features the New 52 and pre-New 52 versions of Lois Lane. Following the death of the New 52 Superman, DC Rebirth features a story arc where the pre-New 52 Superman is confronted with the mystery of how Clark Kent can be around - a completely human Clark Kent with no super-powers, who recalls a life as an ordinary human being and denies having ever been Superman. Superman Reborn reveals that the pre-New 52 Superman was actually split into two, one of whom was the New 52 one, and they remerge at the end. Additionally, the "human Clark Kent" was really Mr. Mxyzptlk.
  • Part of the plot of Zero Hour! deals with this as characters meet alternate versions of each other, most notably including a Barbara Gordon from a universe where she was still Batgirl rather than Oracle, she and her Batman were lovers, the Joker opting to kill Commissioner Gordon instead of crippling her, going on to kill Sal Maroni before he could disfigure Harvey Dent, and much like in The Dark Knight, deciding to disfigure Dent himself.
  • Waverider from Armageddon 2001 and the leader of the Linear Men from the Superman stories "Time And Time Again Again" and "Time Ryders" are both Matthew Ryders from two different timelines — Waverider came from one in which the Monarch destroyed all superheroes and came to power as Earth's sole ruler, while Linear Man Matthew Ryder came from one in which Monarch's plan to destroy all superheroes was averted (the one that ultimately became part of the mainstream DC Universe canon). Initially Waverider had a bad relationship with the other Matthew Ryder and even at one point killed him, which ended up trapping him, Superman, and the Linear Men in a Nullsphere until Waverider used Hunter's eye beam energy to prevent the other Matthew Ryder from being killed in the first place, thus restoring things to normal. In Zero Hour!, Waverider was fused with Monarch to become Extant, forcing Linear Man Matthew Ryder to become the new Waverider in his alternate self's place.
  • Gravity Falls: Lost Legends: "Don't Dimension It" has Mabel getting trapped in a pocket dimension with dozens, even hundreds, of alternate versions of herself. Unfortunately, almost all of them are as self-absorbed and scatter-brained as she is, and the one who isn't turns out to be the villainous Anti-Mabel.
  • Wonder Woman was the first DC comic to officially run an Alternate Universe story, in which Diana helps her counterpart from another universe fight the race of giants that are tyrannizing her world.
    • In Wonder Woman (2006) the villain Genocide is revealed to have been developed using the corpse of a Diana from another world.
    • In Wonder Woman: Odyssey the Big Bad Nemesis is the twisted form of an Alternate Universe Diana, who has been slowly losing her mind due to her burden as Nemesis and plans to force Diana to become the new Nemesis by killing her.
  • Several iterations of Deadpool exist in within the main continuity and in alternate universe books:
    • The Deadpool Corps of Deadpool Corps are other versions of Deadpool, known by different names to readers and nicknamed by the main version to: distaff counterpart Lady Deadpool ("Boobs"), Marvel Zombies severed head Headpool ("Shorty No Pockets" aka "Shorty"), lil tyke Kidpool ("Tito"), and animal superhero Dogpool ("Cujo"). They originally team up to battle a multiverse-devouring cosmic threat.
    • Deadpool Kills Deadpool features Deadpool killing Deadpool. That is, one version of Deadpool targets and slaughters multiple previous versions of himself and new ones created for the book, including the Deadpool Corps and Deadpool Pulp. There's a large-scale battle involving many, many more Deadpools.
    • The Ultimate Marvel version of Deadpool is even more violent than in the main universe, and is a grotesque, evil, mutant-killing bigot.
  • The Mighty Morphin' Power Rangers face this in the Boom! Studios series, in the form of Lord Drakkon for Green Ranger Tommy, Drakkon's Ranger Slayer for Kimberley, and depowered counterparts for Zach and Trini as lead members of The Coinless. Jason and Billy's counterparts are dead, having been killed by Drakkon himself.

    Fan Works 
  • Abraxas: There are essentially at least two versions of San, as the San who serves as one of the story's two main protagonists, having come from the severed Ghidorah-head via Brain Uploading, only has memories of Ghidorah's actions up to the head's decapitation, and doesn't remember what his regrown counterpart did before Ghidorah's death — kind of like an outdated backup file copy. Another version of San who has the same pre-Upload memories and is still evil, has regenerated alongside Ni and Ichi via Ghidorah's surviving DNA traces. The evil San at one point scorns the San who's fused to Vivienne as being nothing more than a "shadow" or "shed skin", and has no apparent compunctions against using Break Them by Talking and Mind Rape on San and Vivienne. Vivienne is able to tell the two San's apart when the evil one speaks to her via Psychic Link, as her San's mental voice is slightly changing with his Character Development, whereas the evil San's voice sounds the same as when San first fused to her.
  • Child of the Storm: Harry spends most of chapter 41 of the sequel Ghosts of the Past talking to an older version of himself thanks to an enchantment malfunctioning under his powers' influence, and the cracks in reality left over from Chthon's rising at the climax of the first book. The counterpart refers to himself as "Nathan" for simplicity's sake, and comes from a timeline where Wanda adopted him after the events of his First Year. He then shows Harry a number of other alternate timelines, varying from the hilarious to the horrifying (and all apparently picked out by Harry's subconscious), in aid of teaching him a lesson or two - though he refuses to spoon-feed him. He later reappears, teaching Jean and Maddie about the ins and outs of the Phoenix.
  • Crisis of Infinite Twilights is built entirely around this. Scootaloo accidentally causes a magical explosion that shatters Twilight and also opens portals across the globe allowing alternate Twilights to appear. From one that was the Princess of Equestria with Celestia as her student, one who is pure evil, one who is a shark, a Japanese Magic Girl, and one who is the leader of the 3rd Row Saints, each chapter introduces at least one new Twilight, leading to an epic battle of hundreds of Twilights fighting it out.
  • A Crown of Stars: A fact of life in Avalon is that you will inevitably run into yourself at some point (almost literally in Shinji's case), or even children you never had. Asuka and Shinji, the pair the story follows, were profoundly weirded out when they bumped into their analogues from “The Way out Is Through” universe. More so when they got a call from their daughter, who was also twice their age (it's apparently good custom to introduce yourself to your analogues and welcome them to the family, though Senior Fleet Commander Sohryu-Ikari also couldn't resist the urge to mess with their heads a little; she got it from her mom).
  • Daydreams And Nightmares actually points out in-universe that Storm is an alternate self of Shanzira.
  • This idea is explored in detail in the Discworld fic Doppelgangers, by A.A. Pessimal, which builds on a scene in The Light Fantastic where Rincewind is flipped onto Earth and for a moment sees life on Earth through the eyes of his alternate self there. Establishing a link between Discworld and Roundworld (Earth), the story builds and establishes clear links between the two worlds. Rincewind turns out to be not the only Discworlder to have a Doppelganger on Earth...
    • The fic Slipping Between Worlds takes this a step further, tidying up loose ends from Reaper Man and The Science of Discworld to suggest a mechanism by which people from Earth can end up on Discworld. And not only people (Alice Band) but whole countries turn out to have Discworld alternate selves...
  • Equestria: Across the Multiverse is all about multiversal exploration, so naturally the protagonists run into a lot of these, though not always with the same names (such as the My Little Pony Tales universe versions of Shining Armor and Mayor Mare being Sincere Heart and President Pony respectively), and there being multiple versions of the same person present at the Jaunting Base at any one time is rather common. In fact, one of its residents is an alternate version of Minuette who's Equestria all transcended into virtual beings who lives in their computer systems as Mission Control.
  • Except It Abide in the Vine is built on this, with the majority of the cast consisting of Alternate Universe versions of Steve Rogers and Bucky Barnes: Marvel Cinematic Universe based and Marvel 616 based, Race Lifted, Gender Flipped, a Darker and Edgier Steve and Bucky from a HYDRA-ruled dystopia, and even a Steve Rogers who isn't from New York.
  • Fallout Girls features this frequently, as the Rainbooms start running into the Fallout versions of themselves, their families and their friends.
  • Fate/Black Dawn: In an omake chapter, various copies of the characters are summoned to Chaldea, leading to the canon versions meeting the fic versions. Canon Arturia and Canon Mordred are not amused at alternate Morgan and Mordred, while Canon Shirou gets into a Cooking Duel with alternate Shirou.
    Saber Mordred: So, let me get this straight. Instead of having me commit the rebellion against my Father, you and my Mother fell in love, you basically adopted me, and you staged a war against Father so you could try to convince her to abandon Camelot in favor of living an extremely long life—because you love her.
    Ruler Shirou: That's the basics, yes.
    Saber Mordred: And you taught Your Me how to use a bow, and basically gorged her on sweets, good food, and paternal affection.
    Ruler Shirou: You could say that, yes.
    Saber Mordred: THIS IS BULLSHIT.
  • In the Project Dark Jade fic Her Shadowed Realm (a Crossover between Jackie Chan Adventures and Yu-Gi-Oh!), Yu, "The Jade Empress", came from (and by that, I mean sealed in the Shadow Realm after a Face–Heel Turn) the original JCA universe (or one that's pretty similar), and eventually makes contact with Pegasus, which allows her to make sure the Yu-Gi-Oh world's version of Jade gets a specially crafted deck, which includes a card of Yu. Yu's plans for her counterpart are currently unknown.
  • In An Infinite Number of Pinkies, Pinkie Pie meets a whole slew of alternate versions of herself being gathered together by the alicorn Pinkie Prime for the ultimate party. Ultimate as in final, as Pinkie Prime has grown so bored with her immortality that she's decided to destroy the multiverse and herself with it.
  • In keeping with one half of the crossover being the DC Universe, the Multiverse comes into play Hunters of Justice, when teams RWBY and JNPR use some of the Justice League's tech to see other versions of themselves. Also, while the story takes place in a universe where Brainiac kept Cinder from enacting the Fall of Beacon, thus Yang still has her arm and Pyrrha is still alive, Batman used the same tech to see into worlds where their canon fates did happen and designed armor accordingly to prevent it from befalling them.
  • The Kingdom Hearts fanfic Lost Boys has Maleficent screwing with Sora by showing him his Canon self. She even offers to restore it, but he refuses in the thought that he can't be that happy anymore, not when he's been depressed and traumatized for so long. He falls into a HBSOD as he wonders what on earth he did to deserve his crappy life.
  • Mass Effect: Life is a Game and its sequel have a Reality Warper offer Male!Paragon!Shepard a one-way trip from Mass Effect 3's endgame to the beginning of the series. Upon arriving in his past, Shepard realizes that a Female!Renegade!Shepard has accidentally fallen into his world as well, so he introduces her as his wife.
  • In Neither a Bird nor a Plane, it's Deku!, Harrison Wells, Harry Wells, and H.R. Wells exist in the same world, all working at S.T.A.R. Labs to promote the greater good. They're also drinking buddies and play Secret Hitler with each other. Izuku himself is the Earth-2014.00 counterpart to Clark Kent.
  • Nobody Dies has an entire story arc devoted to this.
  • On a Cross and Arrow is about the main characters of My Little Pony: Friendship Is Magic finding themselves in a Gender Flipped alternate universe and running into their counterparts (Dusk Shine, Berry Bubble, Applejack, Rainbow Blitz, Elusive, and Butterscotch).
  • In Origin Story, Alex Harris is an alternate self of Power Girl. At first, Alex thinks that she is Xander Harris with Kara's memories, but later comes to realize that she's actually a melding of both Xander and Kara, with her own experiences and opinions.
  • The Pony POV Series reveals the main timeline is simply one in a very large multiverse, the Gender Flip universe from On a Cross and Arrow is one of them. This leads to a pretty awesome moment when Applejack teams up with Orangejack, her alternate self from a world were she didn't see the Sonic Rainboom, to fight Nightmare Mirror, another alternate version of her who'd not only gone Nightmare, but become a Multiversal Conqueror. To defeat her, Applejack summons four other alternate versions of herself that represent the other Elements.
  • The Crisis Crossover in RainbowDoubleDash's Lunaverse has the Trixie and Twilight of the Lunaverse show up in the Mane Six's world. Hilarity Ensues.
    • The rest of the Luna Six and Luna herself have followed them. Contemplation of the road less traveled ensues.
  • In With Strings Attached, Ringo briefly stares at his “Beagle” counterpart in the Plaza hotel room in New Zork. The two Ringos don't get to talk because Beagle Brian Epstein is screaming at the “fake” Ringo and threatening him with arrest. Beagle John, who is the only one who knows what's going on, manages to talk Brian into letting “fake” Ringo go free, since an arrest = unwanted publicity = every illusionist and face-changer trying to get into the hotel that way. It Makes Sense in Context.
  • The Avatar: The Last Airbender fanfic The World without the War has an omake in which the cast meet their canon-counterparts. Usually causing freak-outs on both sides. Until Toph meets Toph.
  • This used to be a very common thing in Ranma ½ fanfics at one point.
    • Two different Ranmas meet and talk in Girl Talk, part of The Return fan-verse.
    • Richard Lawson's Definitions Of hell has two Ranmas swap places before meeting up to compare notes.
    • Deb Goldsmith's Equal Halves has a female version of Ranma from a fanfic end up with canon Ranma due to a wish by Kuno.
  • Fractured Sunlight: The focus of the fic is on "Sci-Twi" (Princess Twilight's human alternate) and specifically her relationship with the human version of Sunset Shimmer she knew as a kid.
  • In Through the Looking Glass (My Next Life as a Villainess), Gerald and Keith from My Next Life as a Villainess: All Routes Lead to Doom! switch places with the Geord and Keith from the in-universe game Fortune Lover after all four make a wish involving their current lives by a runestone Gerald and Geord were studying note . Later, the Katarinas from both worlds switch place after making wishes themselves in reaction to the other Gerald/Geord.

    Films — Animation 
  • The My Little Pony: Equestria Girls franchise is a human High School A.U. spin-off that takes place in a parallel dimension to the main Friendship Is Magic series.
    • The first film has FIM Twilight Sparkle meet human versions of her Equestrian friends at Canterlot High. The Stinger of the sequel introduces EG Twilight Sparkle, who spends the third film investigating the strange happenings at the school and naturally freaked out by all these people she's never met knowing her name. It is also briefly discussed much later on in Magical Movie Night, when a character from Equestria asks to visit the human world.
      Sunset Shimmer: Well, I haven't ever seen you in that world. So chances are you aren't gonna run into yourself.
      Starlight Glimmer: something you don't hear everyday.
    • Notably averted by Ex-Big Bad/Hero Protagonist Sunset Shimmer, who originated from Equestria but permanently resides in the human world. The character doesn't seem to have a human counterpart; if she does, they have yet to be mentioned, and even the very idea of a native human equivalent is never discussed in canon, making this is a major source of Fanfic Fuel.
  • Like its source inspiration, Spider-Man: Into the Spider-Verse has multiple versions of Peter Parker from across the multiverse:
    • The one from Miles Morales's universe is an Ideal Hero who has his life together both as beloved NYC icon Spider-Man and regular civilian Peter Parker. Shame about the "being dead" thing. Also, this one is blonde and blue-eyed, while pretty much every other version of Peter has been brunette and brown-eyed.
    • Peter B. Parker is, to put it lightly, in the middle of a midlife crisis, becoming somewhat out of shape and rather cynical in the process.
    • Peter Benjamin Parker (aka Spider-Man Noir) is a comically serious private eye from a universe where it's still the 1930s and everything is in black and white.
    • Peni Parker is a young Japanese-American Genki Girl from the far future who pilots a spider-themed mecha named SP//dr.
    • Peter Porker (aka Spider-Ham), despite his porcine appearance, is not a pig who was bitten by a radioactive spider, but a spider who was bitten by a radioactive pig.
    • While Gwen Stacy (aka Spider-Woman) is not an alternate version of Peter Parker, her dead best friend was, having become the Lizard instead of Spider-Man.
    • The Stinger features the return of 60s cartoon Peter Parker.

    Films — Live-Action 
  • Sliding Doors is built on this trope. Just a few minutes into the movie, the main character misses the tube. But wait, she did get on the tube. Two timelines, and two lives that are quickly becoming more and more different.
  • The Back to the Future trilogy features multiple alternate versions of Marty's family and recurring antagonist Biff Tannen. Biff, in particular, is first a corrupt middle-management bully, then a timid goofball, and finally a murderous Corrupt Corporate Executive with enough money and power to completely screw up Hill Valley and its surroundings.
  • The One goes on the premise that there are 125 versions of a person each existing in their own universe. Every time any of them die, the life-force or energy that harmoniously flows through them from the deceased is equally distributed among the survivors making them faster, smarter and stronger. The Big Bad Yulaw has been going around killing each of his alternates to become the One, with the final battle being between him and Gabe Law with the power of the other 123 deceased alternates split between them.
  • Marvel Cinematic Universe: Quite a few of them were created in Avengers: Endgame, and some survived to appear in later films:
    • When Nebula and Rhodey travel to back in time to the beginning of the Guardians of the Galaxy, past Thanos gets wind of their plans and teleports to their present where he's already been killed. He is accompanied by Gamora, Nebula, the Black Order and his entire army. In the end, Tony Stark wipes all of them but Gamora whose past version survives in the prime timeline and reemerges in Guardians of the Galaxy Vol. 3.
    • When Tony Stark, Cap and Scott Lang travel back in time to the aftermath of the Battle of New York in The Avengers (2012), they encounter past Loki. He manages to snatch the Tesseract and escape, creating a divergent timeline. The Loki series picks up from there.

  • In the Algis Budrys novel Rogue Moon, teleportation is done in the Star Trek way of decomposition and reconstitution. (Star Trek came out later.) Rogue Moon is more interested in the implications though: two copies of the same person genuinely are the same person, so much so that they can communicate with each other using telepathy until they diverge enough. This is useful in investigating an alien machine that kills its occupants. The decomposition is lethal, no ifs, ands, or buts. The scan can then be reconstituted any number of times, but this is a separate process. Rogue Moon is messed up.
  • In the Labyrinths of Echo by Max Frei, Murakoks are people with a life-long (but variable in strength) Psychic Link to lots of Alternate Selves in other worlds. The downside is having to keep one's place in the net—a travel to another world leads to insanity. The only one appearing was Kobanote , the Dean of Beggars in the capitol. He has more than enough of skills magical and social, but turned down an offer to join Secret Investigations, arguing he must be a beggar for the balance between the alternates. He's a very rich "beggar", though.
  • Well presented in the third book in the Rogue Agent series, Wizard Squared, where the reader is presented with an alternate take on the climax of the first book, and the domino effect shows how terribly poorly that universe went when the characters crossover. Interestingly, the point of divergence was a possibility that the character in the original timeline discounted as too dangerous. Cue Evil Overlord.
  • In The Talisman people in our world tend to have a twinner in the Territories. Fundamentally the two people will be at least similar.
  • In the Mistborn series, burning gold lets you see alternate selves had your past been different while burning electrum lets you see various possible futures depending on the choices you make. This usually leads to a strong feeling of Other Me Annoys Me, at least with more self loathing characters, and is described as very disturbing. But in The Alloy of Law it's revealed that you can form a sort of Mental Fusion with your alternate self, though it's not the focus of the plot.
  • The premise of the short story "The Wheels of If" by L. Sprague de Camp is that, as part of a ploy to discredit a political rival, someone in an Alternate Universe comes up with a way to cycle the consciousnesses/souls of seven people in seven universes who happen to be similar enough to count as Alternate Selves. The rival is one of these, ending up with the mind of a man from our timeline. Unfortunately for the villain, the man from our timeline is himself a capable political operator and knows tricks that haven't yet been thought of in the alternate universe.
  • A few examples from Discworld: in Thief of Time the characters Jeremy Clockson and Lobsang Ludd turn out to be the same person, but duplicated due to the unusual circumstances of their birth, being the son(s) of the Anthropomorphic Personification of Time; in Jingo Vimes makes an important choice as he goes to pick up his "Dis-organiser", which normally tracks what appointments he is due to have in the day—he picks it up as his two selves diverge, and each of them get the wrong one, meaning Vimes gets to find out what would have happened if he had made the other choice.
    • The very first Discworld book, The Colour of Magic, has the Wizzard Rincewind flipped onto Earth and for a moment he sees life on Earth through the eyes of his alternate self there. His friend Twoflower also has an alternate self on the Roundworld.
  • Examples of this are seen in a number of books in the Animorphs series: The Stranger featured an alternate counterpart of Rachel while later the The Familiar and the last Megamorphs book feature alternates of the whole team. Interestingly, the third Megamorphs book deliberately excluded Rachel in its presentation of a dystopian future while including everyone else.
  • The Rifter: Ravishan & Kahlil. Kahlil, after a lonely youth training in Rathal’pesha, spent years in Nayeshi waiting to bring the Rifter (John) to Basawar; then his key to the gates fell into John’s hands and John crossed through. He landed at an earlier point in time and met Ravishan the trainee-Kahlil; together the two of them changed history radically. Now the future where Ravishan becomes Kahlil will never happen, but his future self is still over in Nayeshi, not knowing that events he remembers have been wiped out of existence. Kahlil crosses to Bashawar and arrives thirty years after John’s arrival. He doesn’t meet himself because by this time Ravishan is dead. However, he does pick up Ravishan’s memories; he describes having two timelines in his mind as being like the reflection in a windowpane where you can see both the reflection and the view outside, and focus on one or the other. Eventually the two selves merge even further.
  • In TimeRiders, Foster looks to be one for Liam, until City of Shadows when the team finds out that they are all support units and Liam and Foster are separate Liam units.
  • In the first Chrono Hustle story, Jack has a choice between going to the past or the future. He goes to the past. Then in the third story he sends a letter to himself, telling himself to go to the future, which ends up creating a second Jack, who does make that choice.
  • In The World Shuffler, when O'Leary is transported from Artesia to the parallel world of Melange, he encounters several folks who are alternate versions. The princess Adoreanne, who rules Artesia, is now a barmaid of loose morals named Swinehilde, and her consort, the Count Alain, is now a jealous barkeep named Hulk. O'Leary's wife is now a noblewoman, Lady Andragorre, and worst of all, there appear to be several Lafayette O'Learys, from several different worlds, all working at cross-purposes.

  • The seven different timelines formed in Community's "Remedial Chaos Theory" allow for seven alternate versions of each of the seven main characters.
  • Doctor Who:
    • There's a few of these in the Alternate Universe first seen in "Rise of the Cybermen"/"The Age of Steel", including versions of Mickey (known there as Ricky), Rose's parents and Mickey's grandmother. Rose's father and Mickey's gran were already dead in the "main" universe. Mickey ends up deciding to stay to replace his dead counterpart. When it was revisited in "Doomsday", Jackie Tyler also winds up staying to replace her dead counterpart. And an alternate Harriet Jones (a short lived Prime Minister in the main universe) is mentioned to be President of Great Britain.
    • In "Journey's End", the Doctor's severed hand, having absorbed regeneration energy and come into contact with Donna Noble, branches off into a human-Time Lord metacrisis, with the Doctor's memories, but a biology and lifespan closer to that of a human. Conversely, as the metacrisis went both ways, Donna Noble also gained the experiences of the Doctor, which slowly killed her.
    • "The Name of the Doctor": In an attempt to save the Doctor's life, Clara Oswald scattered untold numbers of these all throughout his timeline, all sharing her appearance and high intelligence, as well as her love for adventure, soufflés, and children. Before the Doctor manages to track down the original Clara on present-day Earth, we meet one in Victorian London, and another one in a crashed spaceship. More pop up in the expanded universe — Amy runs into an American version in the anthology Summer Falls, and the Twelfth Doctor and Clara meet a near-future version in a Doctor Who Magazine comic strip.
  • In Farscape, John is "twinned" by an alien device. They are forced by circumstances to split up, and for an extended period of time the series alternates between following one and following the other. Both versions believe that they are the original, and that the other is the copy, but it is abundantly clear that they are both the original.
  • Many Alternate Universe examples in The Flash (2014), due to the introduction of Earth-2 in season 2.
    • Barry isn't a metahuman; Iris is a cop; Joe is a singer and goes by Joseph; Caitlin and Cisco are metahuman villains respectively named Killer Frost and Reverb; Linda Park is a metahuman criminal named Dr. Light; Ronnie is alive, evil and goes by Deathstorm; Laurel Lance is alive, evil, and a metahuman going by the name Black Siren; Henry Allen on Earth-3 is a speedster and the real Jay Garrick.
    • Taken to its logical extreme with Dr. Harrison Wells. Tom Cavanagh has played six versions of Wells, plus two impersonators of the Earth-1 Wells, as of season 3. The Earth-2 "Harry" is a Jerk with a Heart of Gold, while the Earth-19 "H.R." is a Seemingly Profound Fool. There's also Harrison Sherloque Wells, a French Great Detective, whose genius is focused on reading people and solving crimes rather than science.
      • The Council of Wells and the Council of Harrisons further increase the number of Harrys in the multiverse.
    • John Wesley Shipp portrays Barry's father Henry Allen, and the voice of Henry from Earth-2 is also heard on the phone at one point, meaning the same actor voices him. In addition, he also portrays Jay Garrick, the Flash of Earth-3 (Henry at one point mentions that his mother's maiden name was Garrick). In the Elseworlds crossover, he also portrays the Flash of Earth-90, the Earth of the 1990 series (first seen during Barry's original trip to Earth-2).
    • The Crisis on Earth-X crossover introduces alternate versions of Oliver, Kara, Tommy, Quentin, Winn, Snart, Red Tornado, James, and Metallo. Interestingly, Tommy-X is the Prometheus of Earth-X. There's even a Nazi version of the Waverider.
    • Then, the crossover event Crisis on Infinite Earths does this to nearly every major DC property, featuring (or featuring via another character from the same series) alternate versions of Batman (from Earth-89, Earth-66, Earth-9, and Earth-99, Superman (from Earth-96 and Earth-167, and The Flash (featuring the return of the Earth-90 Flash and even a cameo from the DCEU Flash). It also retroactively declares the Oliver Queen from the future timeline of 2046 from Legends of Tomorrow as hailing from Earth-16, features a deceased counterpart for Batwoman on Earth-99, and separates the Titans and Doom Patrol shows into different Earths after characters from the latter series appeared on the former.
  • All the Alternate Universe counterparts of the cast of Fringe — except for Alt Astrid, who has Asperger's/high functioning autism with no explanation for it.
  • Most of the characters in the sixth season of Lost are presented this way: Living very different lives in the two timelines while still being the same persons. Subverted in the season finale, but presented this way throughout the season nonetheless.
  • Ace Rimmer (and his entire timeline) in Red Dwarf.
    • In the episode "Demons and Angels", a replicator malfunction creates two copies of Red Dwarf, crew included. One copy contains all the best elements and the crew are all kind, enlightened pacifists, while the other ship contains their worst elements, peopled by twisted and sadistic versions of the crew.
  • The So Weird episode "Pen Pal" has Annie encounter a version herself from an Alternate Timeline where she spilled grape juice on herself, kicking off a chain of events that led to her becoming a remorseless bad girl. In the regular timeline, Annie chose orange juice instead, didn't spill it, and her life went on as normal.
  • The Stargate-verse really likes this trope, though they tend to invert it and have the alternate-universe counterparts show up in the main universe.
    • Stargate SG-1:
      • The episode "Point of View" has an alternate Sam who comes to the main universe running away from a Go'a'uld invasion. When they go back into her universe to help fight the invasion off, Teal'c ambushes, kills, and replaces his own alternate self.
      • The episode "Ripple Effect" has multiple copies of most of the main characters, and one memorable scene of an entire room full of Sam Carters trying to solve the problem that's causing them all to converge in the same place, with a table full of blue jello. The episode's villains turn out to be the first set of duplicates to show up.
    • Stargate Atlantis:
      • The episode "McKay and Mrs. Miller" has an alternate-universe McKay ("Rod") who shows up to ask them to stop destroying his universe with the experiment of the week.
      • The episode "The Daedalus Variations", the team discovers the corpses of their alternate-universe counterparts and McKay has to bootstrap on his own dead self's research. Later in the episode, Sheppard fights off a mysterious alien ship with the aid of yet another alternate version of himself. Much ego stroking occurs between the two Sheppards.
  • William Thomas Riker in Star Trek: The Next Generation was split in a Transporter Malfunction. The two alternate selves were the same person at the time of the split, but one of them lived on Enterprise while the other was shipwrecked on a deserted planet for several years. This other Riker later calls himself Thomas Riker (using their middle name) and builds a separate life for himself. There is also the fact that the Riker who stayed behind never got the chance to be promoted to the rank of Commander (he's still a Lieutenant), leading to at least one ironic situation where Riker is essentially giving himself orders.
    • Thomas appeared again on Star Trek: Deep Space Nine posing as Will Riker. The only person who notices something amiss before the reveal is Chief O'Brien when Riker doesn't greet him as a friend during a chance encounter.
  • In the Supernatural episode "What Is And What Should Never Be" (S02, Ep20), we see an alternative version of Sam based on what he would be like if his mother lived.
    • When a Nephilim is born, a rift opens up to an 'Apocalypse Universe' where Michael has taken over. Several previously-killed characters have alternates in this Universe that subsequently become regulars when a group of Apocalypse World inhabitants is brought over to the main 'verse.
    • And in "Destiny's Child" (S15, Ep13), the boys encounter incredibly rich versions of themselves that are heirs to a worldwide hunting business and have a tech malfunction while dimension-hopping. Hunting isn't just the 'family business' for them, it's the family Big Business. All involved are a bit weirded out by the encounter.


  • In Glowfic most of the characters are alternate versions of character "templates". They have usually almost identical appearances and personalities, and most templated characters will have similar names, to varying degrees, for example the "Bell" template always have the syllable "bel" somewhere in their birth names, unless the phonetics of the local language doesn't support it, in which case they will have the closest equivalent that works with the language. Even some characters that were originally unique have subsequently had alternate versions found when new worlds are discovered.

    Tabletop Games 
  • The GURPS Infinite Worlds sourcebook has an over-the-top version of this, in which a large number of Alternate Selves of Lord Byron — including a sea captain, a republican revolutionary, a vampire, and a female vampire hunter — all meet each other.
  • The Tangents sourcebook for Alternity refers to these as "Persistants", or Persistant Individuals. While most parallel individuals don't vary too much, the backgrounds of some of these individuals can vary greatly, depending on the universe they live in, and within an infinite number of universes, there isn't necessarily any logic behind an individual being the head of a Fortune 500 company in one reality and be the night janitor of the same company the next reality over.

  • The Musical If/Then follows a woman named Elizabeth as she takes two alternatives (as "Liz" and "Beth") in starting her new life in New York.

  • The Transformers franchise has dealt from this from time to time, most notably, Transformers: Shattered Glass, Transformers Timelines and tie-in comics for Transformers Cybertron. When Hasbro decided to incorporate Transformers Aligned Universe into the larger Transformers multiverse, the original Thirteen Transformers fell into this, as the Aligned!Thirteen featured a few members who'd be incompatible with the larger Multiverse version as a whole, including Alpha Trion and especially Optimus Prime. Ask Vector Prime confirmed this as Mutliverse!Vector Prime (who, across all non!Aligned universes is the same 'bot from Cybertron) identified his Aligned incarnation as a distinct and separate entity.

    Then came "Another Light", which put an end to multiversal singularities altogether, meaning that retroactivly, the Fallen seen in the Dreamwave comics and the movies aren't the same guy themselves, but separate entities as well.
  • BIONICLE has several alternate universes, most of which have at least a few alternate selves of heroes and villains, sometimes where one became the other (such as good Teridax from the Melding universe). Of particular note is the "Dark Mirror" universe, in which main universe!Takanuva meets alternate Takua, and "The Kingdom," where he teams up with Turaga Takanuva. The former situation has a minor case of Other Me Annoys Me, but all in all Takanuva gets along with himself pretty well.

    Video Games 
  • Injustice: Gods Among Us is an alternate universe where The Joker blows up Metropolis, and Superman kills him, which is the Start of Darkness that leads to a Face–Heel Turn for Supes. The characters of the main universe end up going to the Injustice universe, and have to deal with the corrupt, totalitarian state that it's become, including many Alternate Selves that have also made a Face–Heel Turn. Main!Superman especially calls out Injustice!Superman once the two finally come face to face.
  • In the video game Spider-Man: Shattered Dimensions, three of the four Spideys are alternate Peter Parkers.
  • Shows up in BioShock Infinite, thanks to the multiverse exploration aspect of Elizabeth's "tears". Turns out not only is Rosalind Lutece's "brother" Robert actually an alternate version of herself according to her audio logs, but Booker DeWitt is actually an alternate version of the game's Big Bad, Zachary Hale Comstock.
  • Tales of Xillia 2
    • Shows up a lot, due to a large portion of the plot involving heading to fractured dimensions - versions of the prime dimension, but with minor altercations. Several of the characters encountered (and fought) are some of those who have died during the previous game. Some, like Gilland, are not much different. But there are some like Agria or King Nachtigal, who are very different.
    • There are also alternate selves of the party members, but due to how their journey goes, are usually never met. But there is the special case of Alternate Milla. In her dimension, she succeeded in destroying Exodus at a young age and has lost her status as Lord of Spirits since, and her personality is vastly different from regular Milla. The party also encounters Ludger's alternate self in a fractured dimension, but it turns out that this Ludger has gone insane over his knowledge of being from a fractured dimension, has killed majority of the Xillia cast and is intent on killing Ludger, to take his place.
  • Fire Emblem Awakening features this due to time travel. All of the second-generation characters get alternate selves in the "Future Past" DLC episodes, Morgan gets a second alternate self in said DLC episodes, and the playable version of Yen'fay is explicitly an alternate self to the NPC version of the character.
  • The Legend of Zelda: A Link Between Worlds: Lorule has counterparts to the inhabitants of Hyrule, most notably Hilda and Yuga, who are the counterparts to Zelda and Ganondorf, respectively. Link is aided by his own counterpart in the form of the shopkeeper Ravio, who keeps his face hidden by a rabbit mask until the ending of the game.
  • Chrono Cross makes extensive use. The game's set up us that when the main hero was a child, he was attacked by a demonic panther. In one world, he lived, in the other world, he died. This is what allows him to travel between worlds. Some characters are also changed between worlds-the main hero's childhood friend is far more somber in the other world, and his mother is nowhere to be found.
  • In Shin Megami Tensei IV, when traveling to the Alternate Timeline of Blasted Tokyo, you meet a man named Akira. After leaving Blasted Tokyo, you are taken to another timeline named Infernal Tokyo, home to another Akira. Their timeline diverged with the events of the nuclear war twenty-five years previous; in Blasted Tokyo, the nukes were allowed to strike, while in Infernal Tokyo, the crisis was averted, with the coda of the advent of demon technology. It's also heavily implied that there's a third Akira in the original universe, who eventually became King Aquila of Mikado. All three Akiras share the fate of being crowned King of Tokyo or its nearest equivalent. In the same vein, the main protagonist's previous incarnation was part of the history of these alternate timelines and was in fact pivotal to the development of all three.
  • Many of the characters in the Sega Dreamcast Action RPG Napple Tale exist in two places — one in Napple Town and another one, described as a warped mirror image out in the "seasons" — the game's platforming levels. The characters aren't identical, but they are linked to each other.
  • Blazblue:
    • Hakumen is Jin Kisaragi's alternate self. Specifically, he's from a timeline when Noel Vermillion didn't exist, and Tsubaki was his secretary. Tsubaki is killed by Nu, trying to stop Jin from going after Ragna as he normally does in the present timeline. When Nu tries to fuse with Ragna like she always does, Jin runs after the two and flung back in time as a result. His body is damaged beyond repair, and so he is installed in the Susanooh unit which explains his current appearance.
    • Blazblue Bloodedge Experience's takes place in one of the franchise's many alternate timelines, connected to all the other ones by the Boundary. The protagonist is Naoto Kurogane, who is eventually revealed to be the Alternate Self of the main series protagonist Ragna the Bloodedge. When Naoto enters the main series timeline in BlazBlue: Central Fiction, Rachel remarks that his presence makes Ragna's own existence thinner. Bloodedge Experience also has Raquel Alucard, the counterpart to Rachel Alucard, and like Ragna Naoto has a sister named Saya.
  • Elsword gives us the (as of this writing, unreleased outside of Korea) third job path for Add, the Diabolic Esper, which invokes this in its backstory. Specifically, Add perfected the ability to go back in time to prevent his family from being killed, but he miscalculated and wound up in another timeline in which he found that his family had never been killed and his young self was living happily with his family.
  • In Mario & Luigi: Dream Team, when traveling through Luigi's dreams, Mario is accompanied by "Dreamy Luigi", who is significantly braver than the waking world's version, and possesses many abilities the real Luigi doesn't.
  • In The Witch and the Hundred Knight, there are at least 3 alternate versions of Metallia shown throughout the game. One is shown as a high school delinquent, the other is a sick patient in a hospital, and Torude who is revealed at the end of chapter 12 as Metallia questions her about changing her own name.
  • Fate/Grand Order introduced an alternate version of the Fate series' iconic Saber (Altria Pendragon) as a Lancer. This version traded Excalibur for the holy spear Rhongonmyniad; this has some positive benefits (she's more mature, both physically and mentally, because Excalibur suppressed her growth) and some negative ones (like the spear turning her into a Knight Templar). There's even a slight variation on this within the game, as the playable version gave up Rhongonmyniad after 10 years and mellowed out while the NPC version held onto it and went full villain and goddess.
    • A truly shocking example comes in the form of Fou. In another life, they would be more well known as Primate Murder.
  • Dragon Ball Xenoverse takes Dragon Ball Z a bit further with Time Patrol Trunks. Originally simply Future Trunks, the addition of ''Dragon Ball Super's Goku Black arc caused another split, which the sequel ran with by having TP Future Trunks go back in time and save Gohan by defeating Androids 17 and 18 himself before they killed him.
  • In Persona Q2: New Cinema Labyrinth, the female protagonist of Persona 3 Portable is from an alternate timeline where she is the main lead instead of the male protagonist. When she meets the main timeline SEES, she recognizes all of them, but none of them recognize her. Later on when both counterparts meet, they also note that they feel like they know each other.
    Female Protagonist: I'm him, and he's me...?
  • One of major premises in MGCM, as the end of Chapter 12 shows that Omnis and his heroines encounter their alternate selves from several alternate universes. Also it’s revealed that some demons the heroines fight are once their alternate selves from other alternate universes before they’re slain and corrupted by demons and their demonized selves, including the ones from player protagonist Tobio's party.
  • In the Super Smash Bros. series, Mario and Dr. Mario are treated as two different people, despite being the same person.

    Visual Novels 
  • The plot of Princess Debut has Sabrina's alternate self, Princess Sabrina, burst out of her closet and tell her the two must change places as the princess is dreadful at dancing and a huge ball will take place within a month. The cast of the available princes are all alternate selves of her classmates and childhood friend, though their names differ somewhat.
  • Nasuverse
    • Archer of Fate/stay night is this to Shirou Emiya, the main character. He is only able to exist in the same era due to being summoned from outside of the timeline.
    • Due to the mechanics of the Holy Grail War in which the Servants are actually copies of the true spirit summoned from the Throne of Heroes, it is theoretically possible to summon more than one version of a Heroic Spirit into the war, assuming the Heroic Spirit can fit into more than one class. That said, there's no guarantee they'll will be exactly alike, as being summoned into a different Class can result in all manner of personality shifts as a result of being from a different point in their life (for Gilgamesh, being summoned as a Archer has his personality as closer to the arrogant man he was before he befriended Enkidu, and his Caster self would be the Older and Wiser version from after Enkidu's death) to being a completely different person as a result of being from an alternate timeline (Archer from /stay night, Shirou, and their Alter self from Fate/Grand Order).
    • Fate/EXTRA features an Archer who is an Alternate Self to the Archer from the core series. The point of divergence was that while the original Archer made a contract with Alaya, causing him to become a Counter Guardian and come to hate the ideals that his younger self believed in, the Moon Cell Archer became a genuine Heroic Spirit, being much nicer and still capable of believing in his ideals.
  • In Umineko: When They Cry, Lion Ushiromiya is this to Sayo Yasuda, also known as Beatrice, Shannon and Kanon. Lion exists in a world where Sayo wasn't rejected by Natsuhi, thrown off a cliff, and raised to be a servant, only to be driven to create different personas as a way to cope with bullying, heartbreak and gender/body issues. The chances of this world existing is about one in 2,578,917.
  • In Virtue's Last Reward and its sister game Nine Hours, Nine Persons, Nine Doors, this is pretty much the basis for how Phi, Junpei and Sigma are able to know information they can't know. The games work on the multiple world theory, in which every single difference in action, human or otherwise, creates another branching universe. All three of them are able to "know" information, and obtain the same memories that their alternative counterparts in different histories obtained at the same time-frame within their respective universes [e.g, at 3PM on the same day]. It's revealed in Virtue's Last Reward that the reason for this is that they subconsciously perform "universe jumps" where their mind alone is transferred into the mind of another version of themselves. Although technically the Sigmas, Phis and Junpeis can be considered "the same" person in a sense [since they all streamed from the same "point", they're all the same person, just in different "choice paths"], most normal non-esper people have no way to "mind jump" through alternative timelines into their "other selves".

    Web Comics 
  • El Goonish Shive got several full arcs of these in continuity and about as much outside of it. Tedd exists and has self-esteem issues in every Alternate Universe—even the one where aliens fought in the American Revolutionary War and every third or so guy around is a Half-Human Hybrid. In another version, he calls himself Omega Tedd and may or may not be planning to invade the other universes to kill his inferior selves. Eventually. The main character Ellen is herself an Opposite-Sex Clone of Elliot, and has a crisis of identity from the moment of her creation due to having all of the original's memories, personality traits, and extreme reluctance with being trapped in female form, which is only compounded by (later disproven) fears that the cloning process would give her a lifespan of less than a month. She is later granted, through magical dreams, the memories and experiences of one of her own alternate selves so that she can build a separate life for herself as Elliot's "sister."
  • The Adventures of Dr. McNinja:
    • The Mayor, who traveled from the future to save the world from ninja zombies. Then, he discovered that alternate versions of himself had also traveled into the past to save their timelines from various things like Rogue Super Vacuums. Usually, they finish their mission and live a peaceful life away from the city.
    • There's also the time Dr. McNinja made a bunch of clones of himself with the intention of having each one study a different field of science and later merging them all together to become one person with the shared knowledge of all of them. The one tasked with studying agriculture failed to merge due to the intervention of a time traveler, and ended up living a peaceful life as a farmer. His name is Old McNinja.
  • Schlock Mercenary:
    • The wormgates could link one input to multiple outputs, creating "gate-clones". The most extreme case was a scientist named Gav, who went through a clone-gate with nearly a billion outputs, and is now an entire marketing demographic.
      Gav-285074072: There are still over 900 million Gav-clones out there. My activities of the last year can only be understood statistically.
    • Also, at one point Kevyn Andreyasn managed to go back in time to Set Right What Once Went Wrong. The timeclone accomplished this, and then retired.
    • Kevyn did the gate-cloning trick once before, but only made one copy of himself. The original was killed soon thereafter. Kevyn puts down the successful suicide mission on his resume.
    • The gate-cloning trick, in fact, was how the owning corporation ran the wormgates; there would be the output that got you where you were going, and another one at a top secret location, where your alternate selves would be detained, interrogated, and then executed so that they didn't have to feed you or worry about their secret getting out.
  • Charby the Vampirate: The wraith is Zeno from an alternate timeline where he did not die as a child and grew up to be a much taller, imposing and proud Chosen One.
  • The comic The Dreamer features 21st century and 18th century version of several characters, most notably the main character Beatrice Whaley (and so far it is hinted that there are others as well).
  • In Problem Sleuth the character Pickle Inspector has many of these such as Future Pickle Inspector, Past Pickle Inspector,and God Head Pickle Inspector,Past Future Pickle Inspector and Future Future Pickle InspectorThis is then taken to the extreme when One of the alternate Pickle Inspectors Creates smaller and smaller alternate versions of himself until they make all matter on the atomic scale.
  • In Homestuck there's many alternate versions of characters who come from Doomed Timelines, including Davesprite, who's Dave from an alternate future who came to the past and prototyped himself. Also, in the post-scratch session there are alternate versions of the kids, as well as their ectobiological parents. And everyone who plays SBURB gets a dream self as well, so they can play around on Prospit and Derse even while they sleep.
    TT: I think the true purpose of this game is to see how many qualifiers we can get to precede the word "self" and still understand what we're talking about.
    • Trollian allows past and future versions of everyone to communicate with each other through memos. Karkat in particular hates every other version of himself and tends to ban them from his memos as soon as they pop up. Of course, when he's being honest he admits he pretty much hates Current Karkat too. Most of the other trolls actively like their past and future selves or at least pretend to because winding Karkat up is fun.
  • In Relativity, Irina returns to Earth from a successful six month light speed space travel mission, only to find an alternate version of her who already returned after her mission failed one month in, and is in the process of divorcing her wife due to the strain the failed mission put on their marriage. Her wife, meanwhile, hopes being with Irina will give her back the marriage she would have had if the other mission never failed.
  • Guilded Age: Alternate self: Shanna of "Sepia World" is explicitly an alternate universe version of Shanna Cochran from Fans!.

    Web Original 
  • In Keit-Ai and all its derivatives, a boy and the alternate universe version of his crush cooperate in helping them win the hearts of their other selves. However, drama ensues as they fall in love with other instead and question the NATURE of LOVE.
  • Jenny Everywhere has an infinite number of them living in all possible realities. (Thus making her able to fit into any possible story.)
  • Board James: Word of God suggests that the plot twist of the Video Games episode means that BJ is this to the Angry Video Game Nerd (and vice versa), as opposed to the popular fan theory that Board James is a Stealth Prequel.

    Western Animation 
  • Darkwing Duck:
    • The show introduces the concept of a Mirror Universe called "The Negaverse," where the moralities of everyone are reversed. Darkwing's arch-enemy, the villainous Negaduck, is strongly implied to be that universe's version of Drake Mallard, though it's never actually confirmed.
    • Similarly, the comics continuation introduces an entire multiverse of Darkwings who happen to be various different pop culture figures, such as Simba and Lady Gaga.
  • Futurama:
    • In the episode "The Farnsworth Parabox", the characters travel to a whole slew of alternate universes in which they meet their appropriate counterparts. The universe they interact with the most, though, is defined by opposite coin flips, and differing hair colors.
    • In the Futurama movie Bender's Big Score, the paradox-free time travel creates temporal duplicates, however its nature as a paradox-correcting time code means the duplicates are always doomed. Fry's duplicate (created due to time travelling on the day he got frozen) managed to last long enough to become a more mature and savvy version of Fry, and as it turned out was Leela's new boyfriend Lars Filmore.
  • Naturally, Justice League had a two-part episode about this. In a parallel universe, Lex Luthor killed the Flash and, as a result, is murdered by Superman (it's also implied that Lex, who had become President of the United States in that timeline, was about to start a nuclear World War III). This ultimately leads to the remaining five members of the League rebranding themselves as the Justice Lords, who turn the planet into a police state with themselves in control and drop their generalized rules of Thou Shalt Not Kill—yes, even Batman. Since they virtually eliminated all crime, Lord!Batman started fiddling with interdimensional travel and found the main-universe Justice League. Then the Justice Lords decide to do it all again in the Justice League universe...
  • In "Spider-Wars", the two-part Grand Finale of Spider-Man: The Animated Series, Spidey visited a parallel universe where a version of The Clone Saga had happened, and Ben Reilly/Scarlet Spider was fighting against Peter Parker/Spider-Carnage. He was assisted by various other alternate Spideys, including an arrogant armored Spidey from a world where Uncle Ben had never died, a Spidey who had Doc Ock style tentacles, a Spidey who was still suffering from the mutation sickness from Season 2's "Neogenic Nightmare", and an actor from a world in which Spider-Man is a fictional character, played by him in movies.
  • As part of the Spider-Verse event, the Ultimate Spider-Man series had its own feature-length take on a team up across the multiverse, as Spider-Man pursued the Green Goblin from one universe to the next. The participants were new versions of Spider-Girl, Spider-Man 2099, Spider-Man: Noir, Spider-Ham, Spyder-Knight, and even young Miles Morales.
  • Phineas and Ferb the Movie: Across the 2nd Dimension sees the cast of Phineas and Ferb travelling to an Alternate Universe, so naturally they meet their doppelgangers. In the second dimension, Doctor Doofenshmirtz has successfully conquered the Tri-State Area, Perry the Platypus is his brainwashed cyborg henchman, and Candace is the leader of the Resistance. The two Doofs perform an entire song about it!

    Real Life 
  • If the Universe is infinite,note  a hypothetical traveler who went on and on sooner or later would find a copy of him/her/itself, as well as one of the observable Universe left behind. Physicist Max Tegmark has calculated that, in a Universe of that type, the nearest copy of yourself would be at 10^10^28 meters and the closest copy of our observable Universe at 10^10^118 meters.note  What's more, if the Universe was actually infinite, there'd be an infinite number of them.
