A character encounters an "alternate" version of themselves that they greatly dislike. The alternate can be a work of fiction existing only on a written page or Show Within a Show, or a Doppelgänger of some sort (Clone, Time Travel, Alternate Universe, etc). The alternate version may be a thinly veiled caricature that exaggerates negative qualities or emphasizes neutral or even positive traits in ways the original dislikes, or invents traits whole cloth that are highly out of character. Or maybe they're just Too Much Alike. The original is likely to become very angry at the author or the alternate for the real (or perceived) insult.
The "original" may find that For Want of a Nail their alternate version is really annoying, and (if not a fictional creation) the alternate may likewise find the original embarrassing. On the other hand, the alternate may be a much more successful or well developed individual who angers the original by outshining them. Expect at least one of them to say "I Resemble That Remark!" and/or "Why didn't anyone tell me this makes me look fat?"
- The Doctor Who Expanded Universe New Series Adventures novel Silhouette has a psychic shapeshifter who learns how his victim sees themselves and transforms into someone they'd identify with. When he tries it on the Doctor, he discovers the Time Lord has twelve distinct self-images, and doesn't seem to like any of them much.
- "The Three Doctors" (featuring the first three Doctors), "The Five Doctors" (featuring the first five Doctors), "Cold Fusion" (featuring the Fifth and Seventh Doctors) and "The Two Doctors" (featuring the Second and Sixth Doctors) all had them fighting and bickering amongst themselves, with "The Three Doctors" being particularly nasty. The Doctor never got along with himself until a mini-episode featured the Tenth Doctor meeting the Fifth Doctor, who the Tenth Doctor eventually said was his "favourite". It's somewhat fitting that the Fifth Doctor is the only one who's ever totally gotten along with the others, as the Fifth Doctor is the only one who lacked the arrogance and utter-self-assuredness that permeated all the other regenerations to varying degrees.
- Averted in "The Almost People" when the Doctor encounters his Ganger copy, whom he helps to ease through the memories of all his past regenerations at once. And then the two of them start doing everything in tandem, to their delight.
- Played much straighter in "The Day of the Doctor".
War Doctor: You're my future selves?
10th and 11th Doctors: YES!
War Doctor: Am I having a midlife crisis?
- As well as:
11th Doctor: I demand to be incarcerated in the Tower of London, along with my co-conspirators, Sand Shoes and Granddad.
War Doctor: (indignant) Granddad?!
10th Doctor: They're not sand shoes!
War Doctor: (glances at 10's feet) Yes, they are.
- As well as:
- It should be noted, however, that not all of the Doctor's relationships are quite so turbulent. Excluding the very touchy subject of the Time War, Ten and Eleven got along rather swimmingly and were in practically perfect sync, and even the ones that bicker constantly like the Second and Third have been shown to praise each other and work together under the right circumstance.
- Double subverted in the series' only televised multi-Master episode, "The Doctor Falls". Harold Saxon and Missy get along well enough, apart from one or two minor quips, only to end up murdering one another once they actually start being honest about their respective agendas.
- In the sole multi-Master audio adventure "The Two Masters", Crispy!Master really hates his bald incarnation and calls him "my great enemy", which the 7th Doctor takes offence to. He goes so far as to actively search for the Doctor to enlist him in a revenge plot against his later, hairless incarnation.
- This is particularly twisted when it turns out that the bald incarnation and the burned incarnation have actually swapped bodies, with the bald-in-burned Master trying to confront his younger self in his body to get his own form back rather than being trapped in his current husk.
- In the sole multi-Master audio adventure "The Two Masters", Crispy!Master really hates his bald incarnation and calls him "my great enemy", which the 7th Doctor takes offence to. He goes so far as to actively search for the Doctor to enlist him in a revenge plot against his later, hairless incarnation.
- In "The Eight Doctors", the Eighth Doctor visits his previous seven selves, with mixed results; the first three Doctors are particularly hostile towards the Eighth as they resent him giving them advice, the Fourth being more accepting of his future self can be attributed to the Eighth saving his life, the Fifth is generally cooperative despite being frustrated at the Eighth's initial arrival, the Sixth is annoyed at first but soon falls into a comfortable working dynamic with his successor, and the Seventh has a comfortable conversation even as the Eighth is awkward about talking to his predecessor so close to the Seventh Doctor's death.
- The Sixth and Seventh Doctors bicker when they interact in "Project Lazarus", with the Sixth Doctor teasing his future self, but this is tweaked when the Seventh Doctor realises that the Sixth is actually a clone of his predecessor.
- In "The Wrong Doctors", the later Sixth Doctor finds his earlier sixth incarnation (pre-Character Development) to be completely full of himself and likewise, the earlier Sixth Doctor doesn't care much for his calmer self. The two incarnations of Mel don't get along, to the point where one punched the other out! (although it should be noted that the younger Mel was essentially being brainwashed and her mental energy used by an external attacker that compromised her mental state).
- In the Big Finish Doctor Who audio adventure "The Shadow of the Scourge" the Doctor states that inside of his mind sometimes other regenerations (both future and past) show up in "dire times" but all they can do is turn up their noses at the way he runs things. This is presumably true of all Doctors.
- The Slim Jim in this 2000 commercial clearly doesn't like the other Jims too much.
- In one OVA of The Slayers, Lina and Naga face a man who'd obtained a sealed weapon forged by a magician: a magic mirror that created a doppelganger of anyone it reflected with a perfectly opposite personality. While the opposites were too pacifistic to fight, they did drive Lina and Naga into near insanity. In the light novels it is made even worse, as after defeating the enemy they desperately tried numerous methods to destroy the artifact, only for each attempt to result in more doppelgangers. There is supposedly a town somewhere in the Slayers universe made completely of Lina and Naga clones.
- In Aruosumente, the Sage is a mirror image of Legna, but with his calm demeanor and constant questioning of Legna's motives and reasoning, while giving away no clues or answers, he annoys Legna a lot. Legna claims that if the Sage has nothing constructive to say, he might as well not say anything at all.
- In Hero Squared the "normal" Milo is quite annoyed with the Superhero version of himself from another universe (Captain Valor), and vice versa. Valor is less-than-impressed with Milo's selfishness and complete failure to make anything of his life, whilst Milo resents Valor's smug self-righteousness and over-simplified view of the world and how it works.
- The Authority: while crossing over to a Gender Flipped Alternate Universe to talk to their counterparts, Jack Hawksmoor's equivalent is visibly pregnant. When asked about how he feels to see himself female and pregnant, he responds that he doesn't want to find out who the father is.
- Marvel Comics: In the Identity Wars miniseries Deadpool, Spider-Man and the Hulk cross over into an alternate dimension. Spider-Man's alternate version is a Well-Intentioned Extremist, which annoys Spidey. Deadpool gets along famously with his alternate until he discovers that alt-Deadpool isn't Wade Wilson, it's Victor Von Doom. Alt-Wade Wilson is a Big Bad who Deadpool takes down. Bruce Banner discovers that he can't turn into the Hulk in this dimension and is overjoyed, until that gets reversed. Then alt-Hulk and Hulk duke it out.
- One nice example involving Deadpool has him inventing an imaginary version of himself (aka, he willed himself into having a split personality) while trapped inside a room for over 800 years (long story). Why did he do this? To have someone to play hangman with of course. His plan fails when the imaginary Deadpool turns out to be a genius and starts totally kicking Deadpool's ass in the game.
- In one Disney comic, Donald Duck's friends and family force him to spend 24 hours with a duplicate of himself, to show him how annoying he is.
- In Loki: Agent of Asgard, Old!Loki has nothing but contempt for the new, younger Loki who is on a quest to redeem themself and escape their role as the villain of the tale. When the two finally meet face to face, they mock younger Loki and reveal that they'll never stop being the villain Because Destiny Says So. Let's just say Old!Loki doesn't take it well what happens later.
- Similarly, in Young Avengers, Loki is haunted by kid!Loki who constantly annoys them by mocking their wicked schemes, deconstructing their motives, and spouting bad puns.
- When reintroduced in Thor (2014) the jerk does a Loki trademark Me's a Crowd with the twist of all copies being different versions of themself. It literally devolves into a Loki fight over how much the others suck ("I'm beginning to hate myself.").
- In one of the Judge Dredd stories, Dredd's arch-enemy Judge Death escapes from confinement and goes back to Deadworld to restrategize, but a mistake by the dimension-travel scientist sends both Death and the scientist back in time as well. When the two Judge Deaths run into each other, the past one initially runs his claw through the future one's chest. He's ultimately glad after Dredd takes his alternate self back to the future, because he really didn't want to deal with another him.
- In the Post Crisis continuity, Power Girl rather disliked Supergirl for several reasons: she felt Kara's existence made hers redundant, their powers went haywire when they got closer, and Kara's early attitude was bratty (because of Kryptonite poisoning, but neither of them knew that in the time). Although Kara attempted to make amends, they hardly got along. However it's Power Girl who makes Supergirl feel upset in the Post-Flashpoint universe, since Kara feels she's a wreck compared with her alternate adult self.
- Fantastic Four: Present and Future Valeria Richards don't seem to be getting along with each other.
- One issue of Astro City features a comic book editor who publishes fictionalized stories about the local supers. The heroine Nightingale pays him an irate visit to complain about his insinuations of a lesbian relationship between her and her sidekick Sunbird, and then the villain Glowworm beats the crap out of him for depicting him as a white supremacist. He decides to switch to stories about cosmic entities who (he thinks) are above caring what humans say about them. It turns out that they are not so above it all; one day, his office building vanishes with him in it.
- In The Sandman: Overture, the many different "aspects" of Dream are gathered together and immediately start arguing about whether they count as one person or many people. Two Dreams have this side conversation:
Dream 1: Am I always like this?
Dream 2: Like what?
Dream 1: Self-satisfied. Irritating. Self-possessed, and unwilling to concede center stage to anyone but myself.
Dream 2: I believe so, yes. In my experience.
Dream 1: Ah. Fascinating.
- In Issue 12 of the Invader Zim continuation comic, Zim and Dib are accidentally slingshotted into a Bad Future where Zim has conquered the world and declared himself Emperor. Present Zim is naturally initially thrilled by this, but as Emperor Zim is somewhat more mature and competent, he finds his past self to be an idiot, a view which naturally pisses off the younger Zim. This leads to him teaming up with Dib to defeat Emperor Zim and escape back to the past.
- In PS238, some of the characters go to a universe much like theirs, but where metahumans don't exist. Victor, the genius scion of a supervillain family, is horrified to discover that his alternate self is a child pop star. (And this, right after mocking someone who likes Justin Bieber.) Similarly, Zodon not only has to deal with his counterpart hugging him, but getting Cecil's Star Trek reference without even an ounce of shame.
- Waverider from Armageddon 2001 initially had a bad relationship with the leader of the Linear Men when it is revealed that he is the Matthew Ryder that ended up living the life Waverider had lived (or would have lived in the new timeline) and so ended up killing the other Matthew Ryder. This, of course, had the effect of causing Waverider, Superman, and the Linear Men to be trapped in a Nullsphere with no way to escape...until Waverider used the energy from Hunter's eye beam to alter time so that the other Matthew Ryder would not be killed in the first place. Both Matthew Ryders made their amends with each other and Waverider became a new member of the Linear Men.
- Mr Block of Black Science uses his access to transdimensional travel to contact his other selves and negotiate trades. One such trade goes south when both Blocks are equally intractable about their terms.
- Gravity Falls: Lost Legends: One of the stories has Mabel get stuck in a pocket dimension full of alternate versions of herself. Mabel grows frustrated with the other Mabels' poor attention spans, self-absorption, and short-sightedness, which leads to a Jerkass Realization.
- A Crown of Stars: In the first chapter Shinji and Asuka meet their future selves. Asuka found her older self quite irritating. Subverted with her counterpart of the The Way out Is Through universe. Rather annoying her, that timelines Asuka unsettled her a lot.
- The Second Try: Discussed. Asuka thinks her younger self would hate her if she saw what she has become. Shinji argues she is being too hard on herself, and he mentions his younger self would surely be shocked.
- In the Supergirl fanfic Hellsister Trilogy, Lex Luthor of Earth-One can't stand his Earth-Two counterpart; as far as he's concerned, the other Luthor is an ingrate who hasn't gone through his same losses and is unable to appreciate how lucky he is.
"Listen now to Luthor of Earth-One," said Brainiac, whose face resembled nothing less than a metallic death's-head. "He shall be our field commander. We have the worlds within our grasp. It is our time, now."
"Wait one bloody second!", said one attendee, an older man with red hair. "Who appointed that second-rate lab-rat our spokesman?"
Lex Luthor of Earth-One turned, his warsuit primed for action. He recognized the voice. It was his Earth-Two counterpart, the older Luthor who had fought that Earth's Superman. His Man of Steel was dead now, killed in the Crisis. He had never lost his hair. He had never lost a wife or son. On top of that, he had even worked with the Earth-One Luthor, in a joint effort against the two Supermen.
The man was a damned ingrate, and Lex was fully in favor of wiping him out with an energy bolt.
- The My Little Pony: Friendship Is Magic fanfic I Forgot I Was There plays this for serious drama: Twilight accidentally brings her reflection to life, and both Twilights severely resent each other from the very beginning. Their petty competition is the main focus of the fic.
- Calvin and Hobbes: The Series has an episode wherein The Prankster Socrates is cloned, and he quickly finds his clone to be very irritating.
- Happens with Maya and Miho meet in The Dimensionhoppers (technically they are counterparts of each other).
- In the Star Trek fanfic Written in the Stars, Fem!Kirk gets the spirit of her counterpart stuck inside her head. Hilarity regarding the subject of Spock ensues.
Kirk: Well, excuse me, Miss Know-It-All.Kirk Prime: That's Mrs. Know-It-All to you. Recall I'm a married woman.Kirk: How could I forget? Your husband's a true Mr. Know-It-All.Kirk Prime: It's fun having my sense of humour thrown back at me. If a little annoying.Kirk: Just shut up!
- In the The Infinite Loops this is how Classic Spyro and Legend's Spryo tend to act around each other. They've gotten better about it... Mostly.
- Tends to happen a lot when a looper hears about their baseline self's less-than-stellar behavior, since they've often matured over time but the baseline hasn't. For example, the looping version of Diamond Tiara has long since outgrown her childish bullying antics and befriended the CMC, so hearing how her baseline non-looping self pulled some particularly low trick on them really gets to her. Twilight Sparkle isn't too impressed with her past self on most occasions, either, thanks to show!Twilight being an Idiot Hero.
- Though it happens off screen, the backstory timeline for The Bridge shows an encounter between two different incarnations of Godzilla. While it is subverted in the sense they aren't the exact same individual, they do have the same powers, similar appearance; and the same title. One is the grown up Godzilla Junior from the Heisei series, who is a Gentle Giant unless defending what he cares for and goes out of his way to protect humanity. The other is the revived 1954 Godzilla, a Chaotic Evil monstrosity who kills everything in his path. When they met it was this trope turned violent and cranked Up to Eleven. Take a wild guess how their encounter went. With some aid from Anguirus and Gamera, Junior killed his predecessor.
- In The Two Sides Of Daring Do, AK Yearling gets annoyed and jealous of her clone who is stronger and a better fighter than her and can get through ancient traps more easily. It gets to the point where she gives up and decides her clone deserves to be the real Daring Do. They make peace at the end, when they acknowledge they each deserve to live, and the clone needs her help to survive in the real world which is a lot different than the idealized world of the Daring Do novels.
- Pony POV Series:
- During a Vision Quest, Applejack meets her counterpart Orangejack, and they argue and briefly fight. Applejack is annoyed that Orangejack abandoned the farm to become a business pony, and got a loving husband and children out of it. Orangejack is annoyed that Applejack stayed on the farm and basically did nothing with her life except being a farmer, and got to become a hero and have lots of friends. They make peace when they realize they are Not So Different with how they feel about their loved ones.
- Diamond Tiara's mother Golden Tiara gets shown a vision of her alternate universe counterpart Spoiled Rich. Golden Tiara is first comically horrified by Spoiled Rich's botched nose job, then is angered and disgusted by how vain and selfish Spoiled Rich is and how horribly she treats her daughter. The being who showed her the vision then summons duplicates of both Spoiled Rich and Golden Tiara's insane persona Screwball. Golden Tiara beats both of them into submission while vowing to never become like either of them.
- In the Aftermath of the Games universe, Puppy Spike and Dragon Spike can't stand each other. Every time they interact, it leads to an argument, whether it's over the benefits of each other's species, who was cuter as an infant, or whose crush is prettier.
- When Armani and Selene first meet each other in Broken Bow, they immediately get into a fight. However, once matters are straightened out, they get along well enough.
- Used to chilling extent in the Wicked fanfic The Land of What Might-Have-Been, when Elphaba and others find themselves in an alternate universe where the key divergence is that the Elphaba of this reality was subjected to a complex surgery that gave her a normal appearance, but at the cost of driving her utterly insane, fixated on the idea that she only became 'good' when she became beautiful, and thus determined to force others to become beautiful even if that means corrupting their minds. To date the two Elphabas have only interacted directly by proxy- with Empress Elphaba communicating with the true Elphaba through a charm on her champion- but that conversation was particularly harsh, with each resenting what the other represents.
- RainbowDoubleDash's Lunaverse: Crisis on Two Equestrias has the Lunaverse Trixie and Twilight Sparkle run into their show counterparts. L!Trixie thinks her show counterpart is an obnoxious ham, show!Trixie in turn thinks she's a pampered layabout who could use some exercise. show!Twilight is initially not too hostile to her Lunaverse counterpart, until she insults Clover the Clever, but L!Twilight thinks she's just as bad as her (L!Twilight having become a fugitive for mild misuse of illegal magic) on account of the "Want-It, Need-It" incident. They do, eventually, get over this. After nearly being killed by a equicidal alicorn created by their bickering.
- In The Emperor's New Groove, Kuzco spends the first half of the story narrating his life up to getting turned into a llama. After experiencing some Character Development, Kuzco gets into an argument with Narrator!Kuzco, telling him to shut up, and there's no narration for the rest of the story.
- The movie Deconstructing Harry, where fictionalized characters closely resemble real people but with negative characterization. Anger ensues.
- In the sci-fi thriller Coherence, different timelines cross due to a Temporal Paradox caused by a comet passing earth. This allows characters to meet their counterparts from other realities. One of the characters is shown to be extremely hostile towards his alternate versions, up to the point where he picks a fight with one.
- In Last Action Hero, Jack Slater, the character played by Arnold Schwarzenegger in the ''Jack Slater'' film series, comes into the real world, meets the real Arnold Schwarzenegger, and can't stand him. It Makes Sense in Context.
- In Bill & Ted's Bogus Journey, the two actually get on pretty well with their "future selves," before discovering that they're actually evil robot doubles. Evil Bill and Evil Ted proceed to kill them, alienate their girlfriends and try to create a future that is most non-non-heinous.
Bill: That other me is a dick!Ted: Yeah.
- Artemis Fowl: The Atlantis Complex. One of the symptoms sufferers from the Atlantis Complex show is a Split Personality. As Artemis's case worsens, he develops another personality called Orion. While Artemis is an eerily mature Deadpan Snarker, Orion is a mix between a poet and a Hormone-Addled Teenager, who constantly talks about his (and Artemis's) undying love for Holly. Artemis can see and hear everything Orion does, and hates all of it.
- Animorphs: "The Seperation". Mean Rachel is totally annoyed by Nice Rachel.
- In the Everworld series both the Greek and Roman pantheons exist, and they can't stand each other. Especially Neptune and Poseidon who are engaged in an eternal turf war for control of the oceans, and Atlantis in particular.
- A similar situation exists in The Heroes of Olympus. Mostly the gods are content to let their Roman personalities take over when talking to Romans, but when Greeks and Romans start interacting with them at the same time they get splitting (almost literally) headaches. The most extreme example is Athena; an old grudge with the Romans means she seriously resents having to become the Chickified Minerva.
- A Chronicles of Echo episode narrated by Max had a mention that in a less pleasant stage of his life he was ready to choke the version of "Sir Max" living in the city rumours.
- The first half of Robert A. Heinlein's By His Bootstraps consists of the interaction between the protagonist Bob Wilson and some of his past and future selves, due to a very convoluted Time Travel plot. The scene is retold several times, each from the point of view of a different version of Bob — who consistently thinks his past selves are idiots and his future selves are arrogant pricks. It comes to blows eventually. And this would be the man who rules the Earth in the future? Diktor, the future dictator Bob considers a jerk and tries to double-cross, is Bob himself.
- Luke Skywalker and the Shadows of Mindor: There is a great deal of in-universe material about Luke Skywalker, who after all is Famed In-Story. He hates all of it, particularly the portrayal of him, which is often infallible and leads to some people he meets assuming he should be just listened to - he wants them to argue sometimes, point out things he hasn't seen, and so on.
- In The Tin Woodman of Oz, the Tin Woodman returns to the (now empty) tinworker's house and finds his original, flesh-and-blood head. They have a conversation and find they don't like each other.
- Pact stars Distaff Counterparts Blake and Rose Thorburn, the same person born as a different gender. They're very different from one another-where Blake is impulsive and favors the Indy Ploy (with the usual result being Didn't Think This Through) Rose is more meticulous, favors summoning Others to do her bidding, and is quicker to escalate to ruthless levels of force. Naturally, they don't get along-which causes a lot of problems, because they need to work together in order to survive the many enemies which their family has made over the past seven generations, and because they're both trained manipulators who have a tendency of lashing out violently when backed into a corner.
- Emily the Strange: Stranger and Stranger: Both Emilys even call each other 'Other Me' and they definitely annoy each other. Eventually becomes Evil Me Scares Me.
- We Are Legion (We Are Bob): There are a few Bobs that just can't be around others (such as Mario), as well as some odd companions who like to annoy each other (Riker and Homer, Calvin and Goku).
- Babylon 5: When Dr. Franklin takes a leave of absence to work out his addiction to stims, he embarks on a spiritual exercise inspired by Australian Aboriginals called a "walkabout", where on the premise that he has lost "himself", he wanders until he runs into himself, and can have a lengthy conversation working out their differences and subsequently reunite with himself again. A few episodes later, he gets stabbed in Downbelow, and as he lies bleeding on the verge of death he literally sees "himself"—and that self gives him a "Reason You Suck" Speech chastising him sternly for always running away from his problems, with this "walkabout" being one more example of that. He later remarks to Garibaldi that he did indeed "run into himself", and found he didn't like him very much.
- Buffy the Vampire Slayer:
- Vamp Willow thought that the regular Willow was too wimpy, and regular Willow thought Vamp Willow was too skanky and evil.
- In "The Replacement", the Xander who seems to the audience to be regular Xander is annoyed at the suave, confident Xander, but it is ultimately revealed that they are both the "real" Xander, just split into two distinct forms. One Xander is assertive, self-confident and suave, the other is panicky and self-critical.
- When Angelus returns on Angel we eventually discover how annoying the vampire with a soul is to his alter ego. The fact Angelus had to endure rescuing puppies and listening to Barry Manilow completely drives him up the wall, much to Faith's amusement.
- Buffy the Vampire Slayer:
- In the Season 2 finale of Continuum, Alec travels back in time to save his girlfriend's life. In Season 3, the Alec of the new timeline inherits his father's company and learns said girlfriend has a secret past. New Timeline Alec sees Original Alec as a naive romantic fool; Original Alec sees New Timeline Alec as a power-hungry sellout. They end up trying to kill each other.
- Doctor Who can play this trope straight or avert it, depending on the story. Many multi-Doctor stories feature current and past regenerations bickering with each other. As a show primarily about time travel, there are plenty of examples of this trope between different incarnations of The Doctor, The Master and other supporting characters, which can be found in its own folder above.
- On Dollhouse, Topher imprints his personality onto Victor. The two bond a bit fanboying over how hot Bennett is, but when they actually meet the two quickly get on each other's nerves, talking over each other.
- In The Flash (2014), some characters end up facing their doubles from parallel Earths. Not all of them get along, such as Cisco/Vibe from Earth 1 not getting along too well with his evil double Cisco/Reverb from Earth 2, and Caitlin from Earth 1 disliking her Evil Is Sexy version from Earth 2, calling herself Killer Frost. There's also Harrison Wells from Earth 2, who tries to help Cisco and Caitlin find a double to replace him, and ends up disliking several versions of himself from other worlds, including "H.R." from Earth 19. When Harry and H.R. meet up later, Harry is downright hostile, annoyed that there's a version of him that's not a brilliant scientist. He's dumbfounded that Team Flash chooses to keep H.R., even though the latter does prove his worth in the same episode with a totally non-scientific observation that everyone else missed.
- On Friends, Rachel dates Russ, a guy who's remarkably like Ross. Ross finds him completely annoying, being totally unaware that he's basically criticizing himself.
- Walter and Olivia do not like their counterparts in the alternate universe. Walter doesn't like Walternate, because basically, Walternate was hellbent on destroying our universe (and also reminds Walter of how succesful Walter could have been, had he not been institutionalized). Walternate doesn't like Walter because Walter kidnapped his son and caused significant damage to the alternate universe. Olivia doesn't like Fauxlivia because Fauxlivia basically took over her life, committed several murders and slept with Peter, while she was forcibly implanted with Fauxlivia's memories and thought she was her, and Fauxlivia is annoyed with Olivia because Olivia's general demeanor is not as upbeat as Fauxlivia's.
- Both versions of Agent Lincoln Lee, on the other hand, really get along. The main difference between their personalities is that "main" universe Lee is an introvert and a bit nerdy while "alternate" Lee is an extrovert and more confident. They have fun trying to compare their early lives to see what made them turn out so different.
- There is a lot of variations on this on Fringe due to characters meeting their counterparts. One episode involved hunting down a serial killer with the help of his alternate counterpart (who happened to be an expert criminal profiler). The episode hinged on the For Want of a Nail divergence between the two men.
- Kaamelott: A minor example, where Perceval somehow manages to clone himself with Merlin's magic. The Stinger has him introduce the clone to Arthur saying "But for some reason, he's a real dumbass."
- This is referenced in Murder, She Wrote where fictionalized characters closely resemble real people but with negative characterization. Anger ensues.
- A similar plotline in an episode of The Father Dowling Mysteries, in which a novelist adapts one of Father Dowling's cases as a book. Dowling's Expy is depicted as a brawling Irish stereotype, while the nun standing in for the normally tomboyish Sister Stevie repeatedly faints at the sight of blood. Sister Stevie describes her as "a wimp in a wimple".
- McGee, of NCIS, wrote a novel somewhat based on people he knew. As each member of the team learned about how their counterpart was portrayed, they took offense at the idea. Tim made it very clear that the fictional versions weren't the same, but almost everyone said methinks thou doth protest too much. Except Gibbs, who didn't mind because "Special Agent Tibbs" was awesomeness incarnate, did not have sex with cadavers, and was not shipped with the counterpart of another agent because McGee thought they'd make a nice couple.
- Parallax: The Francis from Ben's World initially dislikes Francis Zapmeister as his counterpart's behaviour gets him into trouble on several occasions. He may also be a little jealous of him as he is more outgoing than he is. However, they do work together when the need arises, particularly later in the series when they and the Francis from Forest World use the Francis Cam to communicate with each other across the Parallax, and sort of become friends. More generally, he dislikes the idea of running into his other selves as it is "like looking at [himself] in a mirror, only it talks back."
- Red Dwarf:
- In "Parallel Universe", Cat is pretty excited to meet his alternate dimension counterpart as he thinks it will be a female cat person - it turns out to be a male dog person.
- Rimmer, contrarily, came to hate his counterpart because they were too much alike - she displayed the same creepy sexual behavior Lister called male-Rimmer on earlier in the episode - only directed toward him.
- This happens to Rimmer several times. When he has Holly make a copy of himself, they hate each other so much that Lister is forced to delete the duplicate. After being stranded on a terraforming world and creating some clones for company, they build their society around his weaselly, petty, and cowardly traits and throw him in the dungeon for not being awful enough. When he meets his parallel-universe self Ace Rimmer, Rimmer resents him for being so brave, competent, and handsome (and thereby countering Rimmer's belief that he couldn't help but turn out to be such a smeghead). The disgust is mutual, and after Ace leaves for more dimensional exploration a text-over states that he never finds a Rimmer as loathsome as this one.
- In "Parallel Universe", Cat is pretty excited to meet his alternate dimension counterpart as he thinks it will be a female cat person - it turns out to be a male dog person.
- A constant on Sliders. Every member of the team has met at least one (or five) alternate versions of themselves on different Earths who they can't stand. They range from a Quinn who's a corrupt "mathalete" to an Arturo who tries to take his double's place to a ditzy Wade to an arrogant Rembrandt and more. And that's not counting the versions who are flat-out evil.
- In the Stargate Atlantis episode "McKay and Mrs. Miller", an alternate universe version of Rodney McKay appears. This version is charming, extroverted and socially skilled. The regular Rodney ends up disliking him because everyone seems to like him better. At the end of the episode Teyla, Sheppard, and Ronan reveal that they weren't terribly fond of the alt-universe Rodney, either. Interestingly, "Rod" actually envies Rodney, claiming that the latter doesn't care what people think about him, while the former is too socially-conscious to do that.
- In an episode of Stargate Universe, Doctor Rush gets sent back in time through "a freak of physics" and warns everyone that the very risky plan they were about to attempt was going to fail miserably. The non-time-travelling Rush (who's been very vocal about the risks inherent in the plan) is very smug about this, to the point of completely disregarding time-travelling Rush's ordeal. Time-travelling Rush is not impressed.
- Star Trek: Voyager:
- In "Author, Author", this happens to every character when they see the Doctor's holoplay "Photons Be Free", since he portrays them as anti-holographic racists. He relents and changes the characters to not be so obviously stand-ins for his real life friends after Tom "revises" the program to paint the Doctor as an arrogant and unethical Jerk Ass so he sees how offensive his first draft was.
- There was surprisingly little argument in "Deadlock", because each Captain Janeway knew what the other would do in their situation, though there was an argument about being More Hero Than Thou. The conflict comes in "Endgame", when Captain Janeway meets her future self Admiral Janeway, due to their different experiences and agendas.
- This happens when the Emergency Medical Hologram meets his identical-looking creator Dr Zimmerman (or a diagnostic program based on him, in an earlier episode). Of course, it doesn't help that Zimmerman is a Dr. Jerk who regards the EMH Mark One as an embarrassing failure.
- In one episode, B'Elanna is split into two separate people: a Klingon and a human. The Human!B'Elanna is weak and fearful, while the Klingon!B'Elanna is hyper-aggressive. Neither likes the other, but in the end, the Klingon version is killed, while the human one is told that her body needs both sets of genes in order to survive, so she ends up being reintegrated.
- Star Trek: The Next Generation:
- In the episode "Hollow Pursuits", the main characters are offended by Lt. Barclay's versions of them in his fantasy holodeck adventure. Troi tells them to relax and just take them as amusing homages, until she happens upon her alternate self - a soppy "goddess" in love with Barclay. Riker immediately seizes the opportunity for an Ironic Echo.
- In the episode "Galaxy's Child", Geordi is excited to finally meet Dr. Leah Brahms, the designer of the Galaxy class engineering systems seen as a hologram in the earlier episode "Booby Trap", as she's here for an inspection. During her visit, she encounters her hologram self, repeating that episode's closing lines "Every time you look at this engine, you're looking at me. Every time you touch it, it's me." It goes without saying that she's extremely angry with Geordi.
- "Second Chances" is basically an entire episode of this trope, alternating between Future Me Scares Me and I Hate Past Me. Riker discovers that a transporter accident duplicated him seven or eight years ago, he got out, the other him was stranded on a planet they were surveying and there's no telling which of them is the original. Riker is annoyed by the youthful attitudes and social difficulties of the other. The other Riker chafes at seeing the man who had the career he should have had and who gave up the woman he still loves (Troi).
- On Star Trek: Deep Space Nine, after Weyoun clone #5 is killed in a Teleporter Accident (at least, they never proved that it wasn't an accident), Weyoun 6 defects to The Federation. Weyoun 7 is pissed at him for betraying the Dominion and shaming the Weyoun line.
- Star Trek: Enterprise, episode "In a Mirror, Darkly". In the Mirror Universe, evil Archer comes across a database listing the achievements of his alternate self as a famous captain, diplomat and explorer. As Archer is still only Number Two on Enterprise he's furious, and as he lapses into insanity and paranoia is taunted by hallucinations of this alternate Archer, goading him into a reckless grab for power and fame. Hoshi makes it clear that she doesn't want to know anything about her own alt-self, clearly finding the idea of another "her" disturbing.
- Star Trek: Discovery revisits the Mirror Universe. While few characters actually encounter their doubles, Tilly is visibly uncomfortable with playing the part of her Evil Doppelgänger, who is a mass-murdering psychopath. Ditto for Burnham, when she's forced to play an her equally-terrible double nearly 24/7. In the one case, where a character encounters his double, Prime!Voq's personality finally reawakens in Tyler's body, causing him to attack Mirror!Voq for the perceived betrayal of Klingon values.
- Calvin of Calvin and Hobbes has had this problem, because he takes It's All About Me so far that it becomes "it's all about this me."
- In one story arc, Calvin makes a clone of himself to do his chores for him, but the clone blows him off and goes to play instead. When Hobbes comments that "he's a clone of you, all right", Calvin responds "What do you mean? This guy's a total jerk!"
- When he makes a copy of only his good side, it works out at first because this one is willing to do all the work, but eventually they come to blows over whether they should be nice to Susie, whom the good side openly admits to having a crush on.
- And when Calvin travels to the future to get his completed homework from his future self, three different versions of him end up fighting over which of them should have done the homework. Averted with Hobbes in the same story, as his egotism is of a sort that gets along with itself. "You're right, as always, Hobbes."
- Bill Watterson states, "I think we all would be horrified to meet a double of ourselves and find out what everybody else already knows about us."
- Daniel Amos: The Doppelgänger liner notes include a short story where the narrator sees himself from the outsidewithout realizing that it is himselfand gets so angry at his own flaws that he tries to attack himself.
- Taylor Swift's video for "Look What You Made Me Do" ends with a brief sequence of fifteen different versions of Swift bickering.
- In the Yu-Gi-Oh! game, Warrior Dai Grepher has several potential futures, among them Good (embodied by Knight Day Grepher) and Evil (embodied by Dark Lucious). As seen in the card Different Dimension Encounter (where both Knight Day Grepher and Dark Lucious confront each other) each clearly doesn't like the revelation that this opposing counterpart exists.
- Paranoia has an entire secret society (the Sy-B-LNG Rivals) made up of clones who want to assassinate their active-duty counterparts. Hey, if they're gonna be stuck living in a deathtrap anyway, they at least want to hurry up and do something interesting while they're at it.
- In Portal 2's Perpetual Testing Initative DLC, Cave Johnson is annoyed by most of his alt-universe counterparts, calling them 'backwater universe yokels' and developing a rivalry with Dark Cave.
- Though the latter case is inverted later on:
Cave Prime: [laughs] Oh, Dark Cave, you are the only one around here who gets me.
- Though the latter case is inverted later on:
- In Fate/stay night, Even though he is unaware of his true identity, Shirou has enormous problems getting along with his future self, Archer (Counter Guardian EMIYA), on a purely instinctual level (although the great personality differences may have something to do with it too). The future version, on the other hand, has some very well thought-out reasons for despising the other.
- In the Magical Girl Lyrical Nanoha A's Portable games, Nanoha and Fate are shown to get along really well with Stern and Levi, their Material duplicates, despite the fact that their copies have completely opposite personalities from them. Hayate and Lord Dearche on the other hand... hoo-boy. Before becoming allies, Hayate considered her Card-Carrying Villain of a twin to be an utter pest while Lord Dearche completely despises Hayate's very being. After becoming allies however, Hayate tries to connect with her duplicate much like Nanoha and Fate did, while Lord Dearche... still hates everything related to Hayate, so Hayate alternates between trying to become friends with her and outright Trolling her.
- Averted by the Lutece "twins" actually the same person from neighbouring universes, identical save for "a single chromosome" in BioShock Infinite. Though they engage in some friendly Sibling Rivalry, they're clearly very fond of each other. It's even heavily implied that they're actually in love with one another.
- Dragon Ball Z video games tend to have Future Trunks displaying varying degrees of annoyance with his main timeline counterpart, mainly due to the fact that Kid Trunks is something of a Spoiled Brat (while Future Trunks, who grew up in an After the End hellhole, is well-mannered and pragmatic). Usually though, Present Trunks manages to do something that wins his other self's respect; in the Dragon Ball Z: Budokai games it's Kid Trunks achieving Super Saiyan at a young age, while in Dragon Ball Xenoverse it's GT Trunks coming to the Future Warrior's aid during the Super 17 Saga.
- Note that this doesn't actually come up in the DBZ anime, as Future Trunks only interacts with his other self when the latter is a newborn baby...though he does pull on Future Trunks' hair. It's averted in Dragon Ball Super when they actually get to meet for real and get along just fine.
- The Journeyman Project 2: Buried In Time: After you, Agent 5, acquire a copy of Arthur from Amarax Station, you can jump back to that same place and retrace your steps along the same path. Along the way, Arthur apparently has a problem with how his original self sounds.
Your!Arthur: You know how the things you hate most in others are the things you hate in yourself? Well, this guy's beginning to get on my nerves.
- In Captain Morgane and the Golden Turtle, adult Morgane talks to a younger version of herself, and neither of them is particularly impressed. Young Morgane had hoped to grow up prettier and adult Morgane thinks her younger self is a brat.
Young Morgane: If I'm honest, I'm a little disappointed.
Adult Morgane: I don't ever remember myself being this obnoxious.
- In Mass Effect 2, Commander Shepard, who by this point is Famed In-Story because of the events of the first game, is told about a VI (an artificial not-all-that-intelligence, much like a computerized personal assistant) modeled after him/her. In the third game, s/he can actually find one and it promptly begins throwing out dialogue tangentially related to Shepard's imported reputation, boasting that it can predict the real Shepard's responses with 17% accuracy. If anything, the real Shepard is horrified that it might be that high.
- Whenever there are two versions of Bowser in a Mario RPG, expect this trope to come into play. Mario & Luigi: Partners in Time mixes this trope with My Future Self and Me when Baby Bowser and adult Bowser meet, but Mario & Luigi: Paper Jam plays it more straight with Paper Bowser and "regular" Bowser. The Kameks from the two worlds also find each others' laugh to be annoying (even though it's completely identical).
- In Chrono Cross, you spend a lot of time hopping between Home World and Other World, where everyone's lives went slightly or entirely differently. You can bring along party members to meet their other selves, and sometimes they are not impressed—pirate captain Fargo, for instance, is disgusted by the embittered gambling hall operator Fargo.
- During the prologue of LEGO Dimensions, the Batman from the DC Comics universe runs into the Batman from The LEGO Movie. They almost immediately get into a Sissy Fight with each other.
- World of Warcraft: Everything your "Future You" says in the quest "Mysteries of the Infinite" is a direct attack on the player. Never mind the fact that you're both wearing the same kind of equipment... and that the NPC comments on your "old gear." Of course, you can later get revenge of sorts when you get to repeat the quest at level 80 and be the "Future You" for now "Past You." Past you also comments on how much better your gear has gotten.... despite visually wearing the same gear. (Especially if you go back in the future wearing equipment that your past self not only has not yet acquired, but cannot wear at his or her level.)
- Tales of the Abyss has a very interesting and spoiler filled take on the trope: Asch the Bloody is the original Luke fon Fabre and sees his replica as this trope because he doesn't accept him as his own person.
- In Kate Beaton's Hark! A Vagrant normal Watson is displeased to learn of Stupid!Watson, the Flanderized version of himself that Sherlock Holmes is now partners with. He's even less pleased to find out about Gay!Watson.
"How many blasted Watsons can there be?"
- In The Order of the Stick, Haley's mental representations argue amongst each other during her time with aphasia.
- In Schlock Mercenary amorphs ran into a problem with the TV version of them:
Schlock: The TV-me is putting me-me out of a job. [...] Maybe we can kill another TV network. Is there still money in that?
- Sluggy Freelance features an access to a potentially infinite number of alternative dimensions, so there are opportunities for this.
Portuguese Torg: "Are.... you... a... a... embezzle?"Torg: "Embezzle? Embezzle means to steal from a company or boss! I'm a freelance web designer, so I don't have a boss! Why?"Bun-bun: "The word is pronounced "Imbecile.""Portuguese Torg: "Ahh!"
- In "Torg Goes to Hell", Zoë and Riff accidentally rescue the wrong Torg from another dimension — one who speaks only Portuguese. When their Torg returns, he tries to communicate with this alternative version of himself using a phrase book, but only comes up with sentences in the lines of (according to Babelfish) "For the Mondays, I am a shoe." Eventually, the "Portuguese" Torg swipes the phrasebook from his hands and tries himself:
"There's only so much of him anyone can take!"
- In "That Which Redeems", Torg encounters another version of himself who turns out to be a complete jerk, to the point of not going to his girlfriend's, or possibly wife's, funeral, on the basis that he can get any woman now that he's a big "hero"- as well as that he was brought as a Replacement Goldfish for that universe's Torg. In response to this, "our" Torg clubs him over the head with a serving-tray.
- In "4U City Red", Riff meets an old grumpy alternative-dimension-version of himself that's basically the same as he, except older and grumpier. They really annoy each other, especially the young one the old one, though there is some grudging respect by the end at least.
- Spoilerrific example in "Oceans Unmoving". Bun-bun's Arch-Enemy, during his time as a Space Pirate in Timeless Space, is Captain Blacksoul — a mysterious cloaked figure who wants something from him. It turns out that Blacksoul is also Bun-bun, controlling a flying robot disguised in a robe. This "future" Bun-bun has been tossed into Timeless Space a second time and due to amnesia can't remember how he got out the previous time, so he wants to follow himself out. He won't reveal who he is because he knows that he'd attack anyone approaching him and claiming to be him. There's also a bit of a misunderstanding where past Bun-bun thinks Blacksoul wants to kill him to get his ship back when he really just wants to hang around to see what happens. In the end, he's so annoyed at his other self's persistence not to be followed around by Blacksoul that he gives him the concussion because of which he doesn't remember it all. Bun-bun wants to have everything his way and doesn't listen to explanations; two people like that with conflicting goals can't possibly get along.
- Alternate timelines and time travel are a big part of Homestuck, add that to a cast of traumatized teenagers forced to view their personalities again and again, and you have a recipe for fun:
- Dirk later grows to really hate his Auto-Responder (AR), an artificial intelligence cloned from his own brain and which has in the meantime developed in his own weird way. (Into a Troll, mostly.) Though unusually, what Dirk hates about him isn't that he's so different from him, but rather that AR is really an exaggerated version of himself, putting all of his personality flaws into perfect view.
- Defied in the case of Davesprite. Considering how much the rest of the cast tend to get smacked in the face with irony whenever they try to change the timeline for the better, it's notable that the future Dave's motivation for prototyping himself with the present Dave's sprite - to give himself a sprite "that doesn't make me want to flog myself with my own brainstem" (as opposed to Calsprite) - was an unmitigated success.
- Breezy, happy-go-lucky Jade surprisingly gets the worst out of the Beta kids when it comes to other selves. She absolutely loses it after being exposed to Jadesprite's moping for only a few minutes. The fact that she acts very similarly to Karkat annoys her too, but it does cement the burgeoning friendship between her and Karkat
- Though each is only slightly "alternate," Karkat hates versions of himself from different points of his own timeline.
- Vriska is subject to this as well. She declares her alternate self, who was killed by Terezi and has been hanging in the afterlife since, to be a "FUCKING LOSER!!!!!!!!" in huge text. Vriska harshly berates her alternate self when she meets her, which drives her to tears, made worse by Meenah breaking up with alterate Vriska. The bittersweet joke for the reader comes from how mentally balanced and nice alternate Vriska is, and how badly shafted she gets in favour of mainline jerkass Vriska.
- Rose also hates Jasprosesprite^2, a flashing chatty Cheshire Cat version of her who fused with the ghost of her cat. Her reaction to her cat self is bonking on her head with her velvet pillow while saying "Kill. Me."
- Dragon Ball Multiverse: Bra from U16 and Bra from U18 find each others lives (an incredibly powerful and dedicated warrior, and a irresponsible teen uninterested in training) a total waste.
- In Relativity, after a light speed travel accident Irina winds up living in an Alternate Universe, and resents that she's being treated like a copy of her Alternate Self, while her alternate self has to deal with watching her ex-wife treat Irina as her replacement.
- The Ten Doctors: Taken Up to Eleven (so to speak). Four and especially Six are good at pissing off all the others. (Two and Seven find themselves getting along better than expected, though.)
- Red vs. Blue: while exploring Caboose's mind as a ghost, Church encounters Caboose's mental image of Church and is incredibly annoyed by him.
- Later, Epsilon-Church remarks that Alpha-Church and the Director are each "kind of a dick". This, despite literally being a copy of them.
- There was a battle between Courtney Love's 2 twitter feeds. The first one was the official feed managed by a ghost writer, the other was a private feed under a Nom De Plume. Courtney got enraged when the official feed started publishing polite things, and she published not-so-polite things about the official feed on her private feed.
- How It Should Have Ended had the title character of The Amazing Spider-Man get irritated with the whiny Spidey from the 2000s Spider-Man Trilogy.
- SF Debris: Whenever Parody Janeway comes face to face with herself, she gets annoyed...and aroused.
- The Annoying Orange web episode More Annoying Orange reveals that even the Annoying Orange himself finds his own antics annoying when used against him. Said web episode involves the titular character meeting another orange very similar to himself, complete with being annoying.
- RWBY Chibi had Ruby dreaming of encountering the original Ruby, though the "annoys" part only occurs when regular Ruby squeezes the Chibi one until she nearly passes out.
- A very dark version appears in Adventure Time. Lemongrab has obvious self-esteem issues and appears to harbor a lot of self-loathing. He later meets an exact clone of himself, and they start off as very close friends, for over a year. Then, seemingly out of nowhere, Lemongrab begins to grow annoyed by his counterpart, and this frustration soon spirals into full-blown loathing. He later tortures and devours his clone, much to the horror of everyone who witnesses this.
- In Avatar: The Last Airbender, the Gaang attend a play about themselves only to find that everyone has been extraordinarily Flanderized. Everyone is angry and embarrassed except for Toph (who's played by a huge beefy actor) and Sokka, once he corrals the actor backstage and offers suggestions to "improve" the show's humor.
- One episode in The Flintstones had Fred wrongfully take the credit for a heroic act, only to have Wilma find out the truth and confront him with her disgust, ending with "I just hope you can live with yourself!" Suddenly, Fred is bothered by a duplicate of himself, who's even more annoying than he is, eating his food, telling bad jokes, and pulling nasty tricks like giving him an exploding cigar. After only a short time, Fred admits he can't live with himself, tells the duplicate to scram, and then confesses to everyone that Barney is the actual hero.
- Batman Beyond,:
- Terry takes Bruce to see Batman: The Musical for his birthday. Terry finds the jolly, musical Batman to be great fun. Bruce is...not impressed.
- This version of Bruce is also quite annoyed when he meets the younger version of himself in an episode of Justice League Unlimited and sees the younger Batman hang a criminal over the edge of a building. "I can't believe I was ever this green," says the elder version. He takes his cane and moves towards the crook, threateningly. "This is how you interrogate a perp."
- The Ben 10 episode "Ben 10,000" sees a mutual form of this. Ben is brought several years into the future to team up with an older version of himself. The problem is that while present!Ben is his usual immature but good-humoured self, future!Ben has unlocked many more aliens and better commands the Omnitrix, but has also become a loner who's Married to the Job and is now constantly brusque to the point of rudeness. So present!Ben sees future!Ben as a humourless jackass and future!Ben sees present!Ben as an irresponsible punk. Eventually they learn to get along, and it turns out future!Gwen's reasons for bringing present!Ben in was to get future!Ben to unclench a little.
- Code Lyoko, oh so many times.
- The most notable is in Triple Trouble, when Odd is split into three. They fight over who gets to go to lunch, and who has to go to PE class. They also ruin a joke by inadvertently repeating it.
- Another example is in X.A.N.A.'s Kiss. Odd complains to the clone he's fighting, telling it that if it's going to keep changing form, it should turn into a wimp next time. Its next form: Odd. In Revelation, another Polymorphic clone pulls a similar move on Ulrich, this time for strategy rather than mockery.
- Towards the end of the Looney Tunes episode Duck Amuck, the frame shifts, leaving Daffy's top half on the bottom and bottom half on the top... inadvertently cloning Daffy. The two Daffys quickly start arguing with each other:
Bottom Daffy: Now what?!Top Daffy: What are you doing down there?Bottom Daffy: Down here? What are you doing up there? (to audience) Down here(Top Daffy snatches Bottom Daffy into the top frame, which then re-centers)Daffy Prime: Listen, bub, if you wasn't me, I'd smack you right in the puss!Daffy Clone: Don't let that bother ya, Jack!Daffy Prime: (winding up a punch) Okay, buddy, you asked for it!(Daffy Clone gets erased just before Daffy throws his punch, making him miss wildly.)
- Futurama has the main characters travel to an alternate dimension where the characters meet their counterparts and find them annoying despite being almost identical. Except for Bender, who being an egomaniac gets along with his counterpart just fine. The others eventually warm up to their duplicates, too.
- Then there was that time they went to the end of the universe and looked across to see their alternate, cowboy hat-wearing selves. Bender got tired of his alternate self flaunting the hat and decided to leave.
- In Bender's Big Score, Fry is jealous of Lars' romance with Leela, not realizing that Lars is an older version of himself from another timeline. Or something; it's confusing.
- And even Bender proves he's not immune to this trope. Seconds after meeting himself, and apparently agreeing to a course of action, the second Bender arbitrarily decides to try and murder his future-self.
- In Turtles Forever, this is the 2003!Turtles's (Especially Raphael and except for Michelangelo) reaction towards the 80s!Turtles, who are much sillier and less serious in comparison. This is taken Up to Eleven with the Mirage!Turtles, whose immediate reaction to seeing both versions is Kill-On-Sight.
- 2003!Shredder also views his 80s counterpart to be a bumbling fool who isn't worth dealing with. On the flip side, 80s!Shredder was initially overjoyed to have found a competent counterpart who could help to finally rid him of his hated enemies.
- Weird variation in South Park: a giant dragon summoned by overuse of the word "shit" has Cartman's voice - when it's defeated, Cartman says "What a lame voice..."
- In Teen Titans, a character named nosyarG kciD, (an Expy of Bat Mite, a Great Gazoo from the comic books who idolizes Batman), who is Robin from an alternate dimension, comes to try to help Robin heal his broken arm, but Robin doesn't quite enjoy this encounter. His double is massively incompetent, which doesn't help smooth things over.
- In an episode of My Little Pony: Friendship Is Magic, Pinkie Pie makes copies of herself. Her duplicates are obliviously and single-mindedly focused on having fun, to the exclusion of all else — an accusation frequently leveled at Pinkie herself — and it turns out to annoy Pinkie just as much as it does everyone else.
- Phineas and Ferb: The whole premise of the made-for-TV movie is that the main cast travels to another dimension. While Doofenshmirtz is initially on good terms with his alternate dimension counterpart, it doesn't take long for Doof-2 to realize that Doof-1 is absolutely clueless and after having the Otherdimensionator built decides he wants nothing to do with him.
"One of me is fine, but eh, I can be really annoying en masse. I admit it."
- Another special Parodies a Zombie Apocalypse when Doof accidentally creates The Virus, spread by touch, that turns people into mindless clones of him.
- In one episode, Candace ended up splitting into two halves thanks to one of her brother's inventions; one was obsessed with Jeremy, and the other was obsessed with busting her brothers. They ended up singing an entire song about how they dislike each other (though most of the hate comes from Busting!Candace).
- An episode of Rugrats dealt with twins Phil and Lil wanting to be less like each other, and thus adopting the mannerisms of Chuckie and Angelica, respectively. Chuckie became exasperated with Phil's constant over-cautiousness, while Angelica was not at all amused with Lil's new aggressive persona. In the end, both Phil and Lil went back to being themselves.
- In an episode of Steven Universe, Steven uses a time-traveling device to create several time copies of himself for a band. They get along at first, but have a disagreement when the original starts trying to designate each copy as a specific role ("the funny one", "the smart one", etc), and calls them annoying. They eventually start a fight that goes through at least four different areas in spacetime and gathers many more clones.
- In an episode of The Smurfs, an accident with magic causes both Papa Smurf and Gargamel to each split into two separate "twins" of themselves. The two Papa Smurfs try to find a cure to recombine, but they can't get along or cooperate with each other, and cause even more accidents, eventually blowing up their lab; eventually, they decide they have to work on it separately, and draw straws, the loser leaving the village. (The other smurfs decide to help out, half of them leaving with the one who leaves.) Meanwhile, the two Gargamels fare even worse, hating each other to the point of getting into fist fights. When the two Papa Smurfs eventually do find the cure, it turns out the reason both pairs didn't like each other, simply put, was that they were too similar, the Too Much Alike Trope clearly applying in both cases.
- Two Danger Mouse instances:
DM: I'm not going to be pushed around by two percent of me. Come down and put 'em up! (balls up his fists)
- "Four Heads Are Better Than Two" is a zig-zag in that DM is paired with a robot duplicate of Penfold while Penfold is paired with a robot duplicate of DM, both as an experiment from Colonel K. Trouble is, the androids are more trouble with their peripheral partners than DM and Penfold are to themselves.
- "The Good, The Bad And The Motionless" has DM facing his evil alter-ego, a red-colored version of himself with a trident, devil horns and a devil tail. He sets out playing mind games with DM until our hero figures things out and beats the hell out of his devil clone within the mystic amphitheater of Stonehenge.
Evil DM: What? A fair fight? You have to be joking! (evil laugh)
- In the Gravity Falls episode "Weirdmageddon 2: Escape from Reality", Dipper discovers that Mabel has been trapped in a Lotus-Eater Machine that creates her idea of an apparently "perfect world." Although she wants him to stay, she has prepared a "backup Dipper," Dippy Fresh, who's more to her taste.
Dipper: (pounding his fists on the table) I hate him. So. Much!
- In Gargoyles, the Archmage engages in a Stable Time Loop to save himself from his apparent death and acquire ultimate magical power, thus for a while there are two of him at the same time. While it might have made sense for the two to stay together and combine their powers for an even greater advantage over their enemies...the Archmage's arrogance is of a brand that doesn't get along with itself. Despite having just been him not more than 24 hours previous (by his perspective), the "older" Archmage is annoyed and impatient with his past self, criticizing and patronizing him relentlessly throughout their interactions. When the "younger" Archmage achieves the same knowledge and power as his future self, he leaves to fulfill his part in the time loop, and the elder couldn't be happier to see him gone.
Archmage: Finally. I thought he'd never leave.
- Rick and Morty:
- Rick's ability to travel through alternate universes and the general trend of the various versions of him pissing off those in power has resulted in thousands of his alternate selves forming the Council of Ricks, a governing body meant to police themselves. The protagonist Rick hates these Ricks, as they're people who hated government that essentially Became Their Own Antithesis.
- "Big Trouble in Little Sanchez" has Beth and Jerry go to alien marriage counseling which shows couples how the other sees them... by creating a monster out of each partner's perception of the other. Then they show how to make their relationship work and have the monsters love each other. Beth and Jerry's monsters are a giant insect and a spineless worm—and worse, they're codependent, which allowed them to escape! The only way they could stop them is creating a Goddess Beth to kill them. It should come as no surprise that Beth and Jerry divorce.
- Kaeloo: In the episode "Let's Play Astronauts", the main four go to an Alternate Universe where Kaeloo's transformation happens in reverse, Mr. Cat and Quack Quack have each other's personalities and Stumpy is a genius. While Kaeloo, Quack Quack and Mr. Cat hit it off with the other counterparts, Stumpy's math-loving, comic-book hating counterpart annoys him to no end.
