->'''Galinda:''' What is this feeling / so sudden and new\\
'''Elphaba''': I felt the moment / I laid eyes on you\\
'''Galinda''': My pulse is rushing\\
'''Elphaba''': My head is reeling\\
'''Galinda''': My face is flushing\\
'''Both''': What is this feeling? / Fervid as a flame, / Does it have a name? / Yeeessssss! / Loathing! / Unadulterated loathing.
-->-- ''Theatre/{{Wicked}}'', [[AntiLoveSong "What is This Feeling?"]]

Everyone has heard of LoveAtFirstSight. Two people meet and instantly one or both falls in love. Happiness ensues, [[UnrequitedLove except when]] [[VillainousCrush it doesn't]]. On the other hand, sometimes people ''despise'' each other from the first moment they meet, often before they've even really had a chance to get to know each other. That is Hate at First Sight. When it's mutual, there will be lots of blatant antagonism. When it's one sided, the target of hatred [[SomebodyDoesntLoveRaymond might be completely confused.]]

Maybe it's their instincts giving them a hint that they just can't get along with this person or maybe it's just something random and unfounded, but either way one or both characters will simply never get along or at least not without a great deal of trial and tribulation. While you might think that this trope would be particularly common between a hero and a villain, it's actually quite common between two good characters as well.

If for some reason the characters wind up in a long-term relationship, it may be TheMasochismTango. If they ever start ''liking'' each other, they will probably have BelligerentSexualTension or become VitriolicBestBuds. Expect a SlapSlapKiss to be the moment when this switches.

Compare LoveAtFirstSight. See also IrrationalHatred.



[[folder: Anime and Manga]]
* In ''Manga/{{Beelzebub}}'', Hilda and Aoi Kunieda got along okay at first, though Hilda is pretty cold. They didn't hate each other during their first met, but they developed a rival relationship. However, [[spoiler:when Hilda got an amnesia, she became a kind, innocent, sweet and naive girl with an obvious crush on Oga. New Hilda hated Aoi (and [[ButtMonkey Furuichi]]) at first sight, though.]]
* In ''LightNovel/BokuWaTomodachiGaSukunai'' almost everyone is some kind of antisocial misfit, so there's a lot of early antagonism of this sort.
** Yozora hates Sena from the moment they meet while Sena wants to be friends, which gradually evolves into an extremely VitriolicBestBuds type relationship due to Yozora constantly being horrible.
** Kobato ''also'' hates Sena from the instant they meet and for much better reasons than Yozora: Sena acts like a creepy stalker towards her.
** Kobato and Maria subvert it though. They look like they hate each other, but are actually best friends. For Kobato, Maria seems to be the only person she ''does'' consider a friend: She avoids all her classmates who want to get along with her.
* Izaya and Shizuo in ''LightNovel/{{Durarara}}'' hated each other instantly. Shizuo could tell exactly what kind of person [[{{Troll}} Izaya]] [[ManipulativeBastard was]] while Izaya was constantly unable to manipulate Shizuo due to his hostility. This hatred only grew over the years due to numerous [[NoodleIncident Noodle Incidents]] during their high school years, and by the time the series starts, there is no hope of any civility between them.
* Eriri and Utaha view each other this way in ''LightNovel/HowToRaiseABoringGirlfriend'', and part of it is due to their interest in Tomoya.
* In ''Manga/JojosBizarreAdventure'' Dio Brando immediately saw Jonathan Joestar as an enemy the moment he laid eyes on him. Poor Jonathan only wanted to be friends with Dio. It's not until Dio pulls stunts like stealing Jonathan's love interest Erina's first kiss, killing his dog, poisoning his father, and becoming a mass-murdering vampire that Jonathan sees Dio as an enemy. Even then, Jonathan still considers Dio a brother.
* In volume 10 and episode 11 of season 2's ''LightNovel/{{Oreimo}}'', Ayase and Kuroneko both instantly dislike each other the first time they formally meet. Ayase doesn't like her [[spoiler:because Kuroneko broke up with Kyousuke after dating for a while and breaking his heart]], while Kuroneko wonders why Ayase is even visiting Kyousuke [[spoiler:due to the way she tends to treat him like dirt]]. She also remembers Ayase from [[spoiler:an earlier moment when she first found out about Kirino's ClosetGeek tendencies, and how unaccepting she was of it initially.]]
* In ''Anime/{{Pokemon}}'', this is basically Harley's reaction to May.
* ''Anime/PuellaMagiMadokaMagica'': This is Sayaka's attitude with Homura. [[spoiler:Even in previous timelines when the latter was still an adorable little {{Meganekko}}.]]
* [[TheHero Bossun]] and [[TheRival Tsubaki's]] ([[ForgottenFirstMeeting not]]) first meeting in ''Manga/SketDance'' wasn't exactly the best. Basically, Tsubaki barged into the Sket-dan's clubroom and began lecturing them about the school rules, and rather rudely touched upon their DarkAndTroubledPast, quickly getting Bossun's hate. Fortunately, their relationship gets better over time, especially after TheReveal, turning their interactions into SitcomArchnemesis instead. Tsubaki's JerkAss KnightTemplar tendencies also gets reduced as [[CharacterDevelopment the story progress,]] and used to show his {{adorkab|le}}ility instead.
* Sakuragi and Rukawa in ''Manga/SlamDunk''. Sakuragi initially hates him because Aruko (his LoveInterest) has a crush on him (his first reaction to him is an [[UseYourHead headbutt]]), but mostly because he can't accept that Rukawa is, definitely, the star of the team (with his amazing skills). Rukawa, instead, regards Sakuragi as an idiot with zero experience (despite the fact that he knows that Sakuragi has some his hidden talents).
* Yotsuba to Yanda in ''Manga/{{Yotsubato}}''. Yanda tried to enter her house while her dad was away. Yotsuba was taught not to let any strangers in when she's alone. Which leads to her slamming the door on his face. The fact that [[{{Jerkass}} Yanda]] enjoys making her angry on purpose doesn't help improve her opinion of him.

* This happens in every single MarySue fic, when the Sue first meets the characters that the writer hates.
* In ''FanFic/EarthAndSky'', an adult Diamond Tiara describes how she utterly hates Apple Bloom, and has ever since they were placed in the same playpen as foals- even before Apple Bloom actually interacted with her in any way. Even years after they're no longer part of each other's lives, just ''thinking'' about Apple makes Diamond go into long, bitter rants about her.
* Literature/HarryPotter feels this way about Umbridge in ''[[https://www.fanfiction.net/s/11669575/17/For-Love-of-Magic For Love of Magic]]''. He's not entirely sure why as he's met evil people before, but he feels he'd want to punch her even if she told him he just won the lottery.
* Rei felt [[OOCIsSeriousBusiness an uncontrollable hatred]] for Kaworu from the moment she met him in ''Fanfic/AdviceAndTrust'', which only magnified when she actually talked to him. Note that it has less to do with him being an angel, and more to do with the fact that she views him as a threat to Shinji and Asuka's relationship (which is a ''major'' BerserkButton for her). To make it all the more hilarious, he later admits that the human half of him finds her being angry to be incredibly attractive.
* ''FanFic/{{crawlersout}}'': Tom dislikes all of Fem!Harry's potential suitors for reasons he can't quite comprehend or explain yet. However, he ''hates'' Grindelwald almost immediately, because unlike with those other suitors, he can tell Harry is genuinely uncomfortable in his presence.
* Hermione Granger disliked Professor [[Series/BuffyTheVampireSlayer (Ale)Xander Harris]] from the word go in ''[[https://www.tthfanfic.org/Story-23251-5/BarefootXO+Time+and+Again.htm Time and Again]]'' due to both his relatively laidback attitude and that unlike most teachers, he doesn't indulge her need to show off what she knows, both not allowing her to answer every question and marking down her essays for giving too much information.

[[folder: Film]]
* In ''Film/{{Aliens}}'', Ripley immediately detests "artificial person" Bishop upon meeting him in the Marines' mess hall because of her prior experience with a malicious android on board the Nostromo.
* In the Creator/LindsayLohan version of ''Film/TheParentTrap'', Hallie and Annie dislike each other from the moment they first see each other and see they look exactly alike. They start to get along after discovering that they are long lost twins.
* From the moment she first laid her eyes on him, [[{{Film/Madeline}} Madeline]] sees only the bad stuff in [[{{BadassBiker}} Pepito]], calling him a bad hat. Her hatred is sealed when he scares her whole class later that night, dressed as a demon.
* ''Film/NightOfTheLivingDead1968'': Ben and Cooper from the original and the [[Film/NightOfTheLivingDead1990 1990 remake]].
-->'''Ben:'''You know Cooper. I've only known you for a minute or two. But that's enough time for me to see that I don't like you very much. And I'm pretty sure you feel the same about me, so lets just try to stay out of each others' way.
* ''Film/XMenFilmSeries'':
** ''Film/XMen1'': Wolverine and Cyclops show an ''immediate'' disdain for one-another before even a single line of dialogue is spoken.
** ''Film/XMenDaysOfFuturePast'': Judging by the harsh glare the younger Magneto gives to Logan just before he walks away from the Pentagon kitchen, he plainly dislikes him even though the latter hasn't done or said anything negative. It seems highly unlikely that Erik would remember a rude stranger that he once tried to recruit in a bar 11 years prior, and even if he did, his behavior is rather antagonistic for such a minor insult.
* When Django of ''Film/DjangoUnchained'' rides up to Candyland on his horse, Stephen, the head house slave, gives him an utterly ''hateful'' DeathGlare. This is largely due to [[BoomerangBigot his hatred towards his own race in general]], which isn't helped by the fact that Django is free and not a slave.
* The ''Film/HighSchoolMusical'' characters Mr. Bolton and Ms. Darbus have argued since the day they met (incidentally, the same day they were both hired to work at Albuquerque High). Even taking the actual reason for their argument into account, it's clear that they enjoy having an excuse to snipe at each other.
* [[{{Film/Tombstone}} From Tombstone:]]
-->Doc Holliday: Look, darling, Johnny Ringo. The deadliest pistoleer since Wild Bill, they say. What do you think, darling? Should I hate him?
-->Kate: You don't even know him.
-->Doc Holliday: Yes, but there's just something about him. Something around the eyes, I don't know, [[{{Main/NotSoDifferent}} reminds me of...]][[{{Main/EvilCounterpart}} Me.]] No, I'm sure of it-I hate him.

[[folder: Literature]]
* In ''Literature/SalemsLot'' Susan's mother hates Ben almost immediately and fabricates several reasons why. Ben satisfies himself by knowing he gets along with her father while Susan and her mother have a major fight over it.
* Rhea in ''Literature/WizardAndGlass'' instantly loathed the young and beautiful Susan. Susan tried to clear the initial bad impression, but the antagonism remains through the rest of the story.
* In ''Literature/TheSilmarillion'' there are two cases among the elves.
** Idril disliked and distrusted her cousin Maeglin, without really knowing why, almost as soon as she met him, though she didn't hate him. He [[VillainousCrush fell in love with her]] and being unable to woo her, [[LoveMakesYouEvil became so embittered]] he eventually betrayed their whole city and got it sacked.
** Fëanor despised and hated his half-siblings before they were even born, and continued to hate them until he died[[labelnote:*]]and in the afterlife, one can guess[[/labelnote]]. And with the "friendly advice" of the BigBad Morgoth he became paranoid, thought they were out to get him, [[CainAndAbel threatened to kill Fingolfin in cold blood, and then betrayed his siblings and their families]] during the Noldorin rebellion. Fingolfin and Finarfin, having done nothing to actually harm Fëanor, were trying to make peace with him.
* In ''Literature/HarryPotter'', Harry dislikes Draco Malfoy from the start. Partly because of his spoiled attitude (which reminds him of his cousin Dudley) and partly because of his lack of sensitivity when Harry mentions he's an orphan. This ends up cemented later when Draco sucks up to Harry on the train after finding out who he is.
** Harry's father James and Severus Snape (who later became one of Harry's teachers) hated each other pretty much from the moment they met in their first year.
* In ''Discworld/CarpeJugulum'', [[FatGirl Agnes Nitt]] secretly desires to be a "bad girl". Her reaction to meeting actual "bad girl" [[AlphaBitch Lacrimosa de Magpyr]] is summed up as "There ''is'' such a thing as hate at first sight." Unfortunately for both of them, Lacrimosa's brother Vlad keeps dragging Agnes along with the family because he's madly in love with her, ensuring that the two get plenty of chances to despise each other.
* In ''Literature/WarriorCats'', Longtail, Sandstorm, and Dustpelt hate Fireheart the moment he joins the Clan, and the feeling is mutual. Eventually Fireheart [[RescueRomance saves Sandstorm's life and she falls in love with him]], Longtail, without the influence of Darkstripe and Tigerstar, eventually becomes loyal to Fireheart (particularly after Fireheart begins to treat him with more respect), and Dustpelt continues to be a bit of a jerk, but in their old age they begin to relish their rivalry more than anything.
* In Theodore Dreiser's ''Literature/AnAmericanTragedy'', Gilbert Griffiths has this reaction to his cousin Clyde just from learning of the latter's existence.
-->At the thought of a cousin who looked like him — possibly as attractive in every way as himself — and bearing his own name, Gilbert chilled and bristled slightly. For here in Lycurgus, up to this time, he was well and favourably known as the only son and heir presumptive to the managerial control of his father’s business, and to at least a third of the estate, if not more. And now, if by any chance it should come to light that there was a relative, a cousin of his own years and one who looked and acted like him, even — he bridled at the thought. Forthwith (a psychic reaction which he did not understand and could not very well control) he decided that he did not like him — could not like him.
* In ''Literature/DavidCopperfield'', David pretty much has this reaction to Uriah Heep.
* In ''Literature/HeroesOfOlympus'', Calypso immediately hates Leo from the moment he crashes through her dining table and into her divine house arrest. She doesn't even talk to him, she just starts [[RageAgainstTheHeavens screaming at the gods]] that they [[YouHaveGotToBeKiddingMe must be joking]] to do this to her. [[spoiler:she changes her mind later. Reluctantly]]

[[folder: Live-Action TV]]
* A ''Series/ThirdRockFromTheSun'' episode involved Dick getting upset that a cafeteria lady hated him. This is pretty bizarre when you consider how Dick is usually apparently okay with several regular and recurring characters disliking him. In fact, when he got angry that she didn't even hate him for an actual reason, Nina replied "Does she need a reason? 'Cause I can give her reasons."
* Step-siblings Derek and Casey from ''Series/LifeWithDerek'', whose conversation starts out like this:
-->'''Casey:''' I'm sorry, we haven't met-
-->'''Derek:''' And I'm ''ok'' with that.
** After which follows some snarky replies from both sides, with Casey concluding he's the most 'arrogant, insensitive, rude person' she has ever met.
* ''Series/DeadLikeMe'' has [[TheSnarkKnight George]] reacting this way to [[AlphaBitch Daisy]] when she first shows up.
--> '''George:''' I hated her instantly.
* Neatly summed up on ''Series/DontTrustTheBInApartment23'', approximately thirty seconds after Chloe meets June's new AlphaBitch pilates pal:
--> '''Chloe''': Oh! I just realized! I hate you."
* On ''Series/{{MASH}}'', Hawkeye and BJ's first impression of Charles Winchester isn't a particularly good one:
--> '''BJ:''' Let's avoid the Christmas rush and start hating him now.
** Then there's Winchester's predecessor, the even more JerkAss-y Frank Burns:
--->'''Frank:''' What I don't understand is, why do people take an instant dislike to me?
--->'''Trapper:''' It saves time, Frank.
--->'''Frank:''' Well, we got along fine for the first two weeks.
--->'''Trapper:''' Exactly, Frank. And that time was absolutely wasted.

[[folder: Theatre]]
* In ''Theatre/{{Wicked}}'', Elphaba and Galinda (i.e. the Wicked Witch of the West and Glinda in their high school years) sing "What Is This Feeling?", sung almost as if it is a lover's ballad, except instead about love at first sight, it's this. Unlike most examples of this trope, they eventually become close friends with heavy romantic subtext. Currently the page quote.

[[folder: Tabletop Games]]
* In ''TabletopGame/{{Planescape}}'', this was how the Blood War started, eons ago, before mortals appeared. The Chaotic demons of the Abyss met the Lawful devils of Baator. They hated each other, they fought, and never stopped. The war of genocide between the two that has gone on since then where untold billions have been slaughtered [[LawVersusChaos is as simple as that.]]

[[folder: Video Games]]
* In ''VideoGame/DuelSaviorDestiny'' Taiga and his magic teacher Downy loathe each other from the moment they first meet. It's not until the final route that they actually have a conversation that isn't completely hostile.
* Lightning towards Snow in the BackStory of ''VideoGame/FinalFantasyXIII'', mainly because the epic clash of [[IceQueen their]] [[IdiotHero personalities]] and because he plans to take [[BigBrotherInstinct her precious Serah]] (her little sister and his fiancee) away from her. It doesn't help any that Snow is generally quite oblivious to this and keeps trying to treat Lightning as a sister-in-law already.
* ''[[VideoGame/DotHackGU .Hack//GU]]'': Anti-Hero Haseo takes an intimidate dislike to Sakaki when they meet.
* In ''VideoGame/XMenLegends'', it's mentioned that the Professor and the Shadow King experienced this.
* Early on in ''VideoGame/KingdomHeartsBirthBySleep'', Aqua walks past [[Disney/{{Cinderella}} Lady Tremaine and her daughters]] and imminently detects a horrifying amount of darkness in the trio. She plots to assassinate them right away.

[[folder: Visual Novels]]
* In ''VisualNovel/FateStayNight'' Shirou has this reaction at least twice and for similar reasons both times, though he doesn't really consciously recognize it.
** He and Archer are instantly in opposition because Shirou recognizes that Archer embodies his ideals as a hero of justice, but absolutely despises his methods. Archer, in turn, views Shirou as a naive fool whose insistence on fair play, honor and trying to help everyone will just get even more people killed and [[spoiler:will lead him to being crushed by his ideals like Archer himself, who is Shirou's future self.]]
** He's also instantly hostile to Kotomine Kirei, though at first he thinks it's just because Kotomine is TheGadfly and really knows how to push his buttons. However, he may also sense on some level that Kotomine isn't trustworthy. To put a final complication on things, Shirou realizes at the end of the Heaven's Feel route that [[spoiler:deep down he kind of ''likes'' Kotomine because they have so much in common as individuals who lack a sense of self, but knows that he must fight him because their goals--saving humanity and destroying it--are diametrically opposed.]]
* Kyousuke despises Usami from the moment they first meet in ''VisualNovel/GSenjouNoMaou'', though he does his best to hide it. Her passion for justice, her [[spoiler:last name]], her slovenly attitude and her nosiness grate against the antihero Kyousuke. That said, she ''is'' the main heroine of the story, but Usami has to put up with a lot before that.
* Yaginuma and Reiji in are implied to have been instantly antagonistic towards each other in ''VisualNovel/KaraNoShoujo'', though they'd already met before the story began. It's not hard to see why: Yaginuma [[JerkassFacade goes out of his way to be a jerk to everyone]] because of his own traumatic background.
* Akiha has a tendency to hate people quickly in ''VisualNovel/{{Tsukihime}}.'' She instantly takes a dislike to both Ciel and Arcueid. As far as Ciel goes she has pretty solid reasons: Ciel is a member or an organization that [[spoiler:often opposes non human beings such as herself]]. Arcueid, on the other hand, pisses her off because of how whimsical she is as well as being too close to her brother.
* In ''VideoGame/{{Amagami}}'' Miyu instantly has a great deal of loathing for Morishima Haruka, who finds her to be incredibly cute. At first it looks like this is a measure of jealousy due to Miyu being [[LittleSisterHeroine Miyu]], but later arcs show that Miyu is quite supportive of her brother's relationships.

[[folder: Webcomics ]]
* Haley and Crystal in ''Webcomic/TheOrderOfTheStick'' met in the thieves guild and within moments had lethal grudges against each other. This cemented Crystal as Haley's rival, meaning she would always be at the same level as Haley or better.
* In ''Webcomic/{{Homestuck}}'' one form of [[BizarreAlienBiology Troll Romance]] is called kismessitude, a romantic relationship based around hate instead of love. When Karkat sees John for the first time on his computer screen, Karkat instantly develops a "hate-crush" on John, and believes him to be his destined kismesis.

[[folder: Web Video]]
* In ''WebVideo/TwoBestFriendsPlay'', while playing ''VideoGame/TheWalkingDead'', Matt mentions how much he usually hates child [=NPCs=] in video games, and how impressed he is at the writers for making Clementine likable. Then Duck shows up, and Matt's reaction--before Duck even has a chance to speak--is "Oh hell no." For the rest of the playthrough, Matt interacts with Duck as little as possible and laughs at Duck's misfortunes.
* The reaction of Android 16 in ''Anime/DragonballZAbridged'' after meeting Goku, whom he's been programmed to have an obsessive urge to kill, is this. It's played very much like the [[LoveAtFirstSight inversion]]; music plays in the background and 16 gets so tongue tied that he retreats, embarrassed.

[[folder: Western Animation]]
* ''WesternAnimation/TheSimpsons'':
** During one of the more memorable episodes, a new worker joined the power plant named Frank Grimes, who represented an average person dropped into the world of ''The Simpsons''. He quickly became Homer's Enemy, as noted in the episode title, due to how appalled he was at how lax and incompetent Homer was while still having such an idyllic life, which just keeps getting worse as the episode continues. At the end, his hatred gets the better of him and in a fit of anger grabs raw electrical wires while ranting and is killed instantly. [[GallowsHumor At his funeral, a sleeping Homer asks to change the channel and everyone laughs.]]
** One episode from the 2012-13 season ([[Recap/TheSimpsonsS24E15BlackEyedPlease "Black-Eyed Please"]]) featured Creator/TinaFey as a substitute teacher who kept vindictively insulting and punishing Lisa for no apparent reason at all. She eventually admits the reason being is because she thought Lisa was one of those beautiful popular girls that use only their looks to succeed instead of their smarts. Lisa however, is happy that someone actually thinks she's popular and pretty.
* ''WesternAnimation/{{Kaeloo}}'': Pretty and Stumpy start to hate each other from the first time they meet.
