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.
Everyone has heard of Love at First Sight. Two people meet and instantly one or both falls in love. Happiness ensues, except when 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 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 The Masochism Tango. If they ever start liking each other, they will probably have Belligerent Sexual Tension or become Vitriolic Best Buds. Expect a Slap-Slap-Kiss to be the moment when this switches.
- In 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, 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 Furuichi) at first sight, though.
- In Boku wa Tomodachi ga Sukunai 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 Vitriolic Best Buds 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 Durarara!! hated each other instantly. Shizuo could tell exactly what kind of person Izaya was while Izaya was constantly unable to manipulate Shizuo due to his hostility. This hatred only grew over the years due to numerous 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 How to Raise a Boring Girlfriend, and part of it is due to their interest in Tomoya.
- In Jojos Bizarre Adventure 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 Oreimo, Ayase and Kuroneko both instantly dislike each other the first time they formally meet. Ayase doesn't like her because Kuroneko broke up with Kyousuke after dating for a while and breaking his heart, while Kuroneko wonders why Ayase is even visiting Kyousuke due to the way she tends to treat him like dirt. She also remembers Ayase from an earlier moment when she first found out about Kirino's Closet Geek tendencies, and how unaccepting she was of it initially.
- In Pokémon, this is basically Harley's reaction to May.
- This also applies to everyone who joins Ash as a companion-of-the-season towards Team Rocket, even if the trio do nothing towards them at first. Sometimes, one-shot characters and entire groups of trainers will also attack them upon first sight as well, depending on the episode.
- Puella Magi Madoka Magica: This is Sayaka's attitude with Homura. Even in previous timelines when the latter was still an adorable little Meganekko.
- Bossun and Tsubaki's (not) first meeting in Sket Dance 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 Dark and Troubled Past, quickly getting Bossun's hate. Fortunately, their relationship gets better over time, especially after The Reveal, turning their interactions into Sitcom Archnemesis instead. Tsubaki's Jerk Ass Knight Templar tendencies also gets reduced as the story progress, and used to show his adorkability instead.
- Sakuragi and Rukawa in Slam Dunk. Sakuragi initially hates him because Aruko (his Love Interest) has a crush on him (his first reaction to him is an 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 Yotsuba&!. 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 Yanda enjoys making her angry on purpose doesn't help improve her opinion of him.
- Ultimate Daredevil & Elektra: Elektra and Trey hated each other since their first encounter. Things only escalated from there.
- This happens in every single Mary Sue fic, when the Sue first meets the characters that the writer hates.
- In Earth and Sky, 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.
- Harry Potter feels this way about Umbridge in 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 an uncontrollable hatred for Kaworu from the moment she met him in Advice and Trust, 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 Berserk Button 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.
- 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 (Ale)Xander Harris from the word go in 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.
- In 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 Lindsay Lohan version of The Parent Trap, Hallie and Annie become bitter rivals 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, Madeline sees only the bad stuff in Pepito, calling him a bad hat despite his Establishing Character Moment being a case of Pet the Dog. Her hatred is sealed when he scares her whole class later that night, dressed as a demon.
- Night of the Living Dead (1968): Ben and Cooper from the original and the 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.
- X-Men Film Series:
- X-Men: Wolverine and Cyclops show an immediate disdain for one-another before even a single line of dialogue is spoken.
- X-Men: Days of Future Past: 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 Django Unchained rides up to Candyland on his horse, Stephen, the head house slave, gives him an utterly hateful Death Glare. This is largely due to his hatred towards his own race in general, which isn't helped by the fact that Django is free and not a slave.
- The High School Musical 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.
- 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.
- In 'Salem's Lot 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 Wizard and Glass 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 The Silmarillion 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 fell in love with her and being unable to woo her, 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* . And with the "friendly advice" of the Big Bad Morgoth he became paranoid, thought they were out to get him, 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 Harry Potter, 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 and partly because he speaks poorly of Hagrid (the first person to show Harry any kindness). This ends up cemented later when Draco sucks up to Harry on the train after finding out who he is (and after being a jerk to Ron, Harry's soon-to-be best friend and eventual brother-in-law).
- 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 Carpe Jugulum, Agnes Nitt secretly desires to be a "bad girl". Her reaction to meeting actual "bad girl" 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 Warrior Cats, Longtail, Sandstorm, and Dustpelt hate Fireheart the moment he joins the Clan, and the feeling is mutual. Eventually Fireheart 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 An American Tragedy, 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 fathers 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 David Copperfield, David pretty much has this reaction to Uriah Heep.
- In Heroes Of Olympus, 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 screaming at the gods that they must be joking to do this to her. she changes her mind later. Reluctantly
- A 3rd Rock from the Sun 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 Life with Derek, 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.
- Dead Like Me has George reacting this way to Daisy when she first shows up.
George: I hated her instantly.
- Neatly summed up on Don't Trust the B---- in Apartment 23, approximately thirty seconds after Chloe meets June's new Alpha Bitch pilates pal:
Chloe: Oh! I just realized! I hate you."
- On M*A*S*H, 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 Jerk Ass-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.
- Then there's Winchester's predecessor, the even more Jerk Ass-y Frank Burns:
- In 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.
- In 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 is as simple as that.
- In Duel Savior Destiny 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 Back Story of Final Fantasy XIII, mainly because the epic clash of their personalities and because he plans to take 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.
- .Hack//GU: While Anti-Hero Haseo is prickly towards anyone he meets for the first time, he takes a particularly strong dislike for Sakaki right off the bat which is later proved to be well justified.
- In X-Men Legends, it's mentioned that the Professor and the Shadow King experienced this.
- Early on in Kingdom Hearts: Birth by Sleep, Aqua walks past Lady Tremaine and her daughters and imminently detects a horrifying amount of darkness in the trio. She plots to assassinate them right away.
- In Resident Evil 7, Ethan experiences this about Lucas just by looking at a picture of him, with the game informing the player that "You don't know him, but you get the feeling he's an asshole."
- In Fate/stay night 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 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 The Gadfly 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 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 G-Senjou no Maou, though he does his best to hide it. Her passion for justice, her 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 Kara no Shoujo, though they'd already met before the story began. It's not hard to see why: Yaginuma 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 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 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 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 Miyu, but later arcs show that Miyu is quite supportive of her brother's relationships.
- Haley and Crystal in The Order of the Stick 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 Homestuck one form of 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.
- In Two Best Friends Play, while playing The Walking Dead, 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 Dragonball Z Abridged after meeting Goku, whom he's been programmed to have an obsessive urge to kill, is this. It's played very much like the inversion; music plays in the background and 16 gets so tongue tied that he retreats, embarrassed.
- The Simpsons:
- 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. At his funeral, a sleeping Homer asks to change the channel and everyone laughs.
- One episode from the 2012-13 season ("Black-Eyed Please") featured Tina Fey 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.
- Kaeloo: Pretty and Stumpy start to hate each other from the first time they meet.
