A character with a hair-trigger temper flies into a rage at the slightest provocation. Masters of DisproportionateRetribution, they react explosively to the slightest annoyance. Unlike someone with a BerserkButton, who is generally calm until a specific button is pressed, characters with a hair-trigger temper can be set off by ''anything''. This makes them far less predictable -- and far more dangerous.

In comparison to the "avoid the BigRedButton" approach with someone with a BerserkButton, conversation with someone like this is like trying to navigate a minefield without a metal detector. You know the danger is there, but you have no clue exactly where it is. At best he's tetchy and anxiety-inducing. At worst, he's a surly, dangerous, ticking time bomb. The very act of talking to them might be enough to set them off. Trying to ''joke'' with them is downright suicidal. Many of these characters don't need a reason; they want an excuse. Extra points if they then pull a WhyDidYouMakeMeHitYou, to make the "offender" [[WoundedGazelleGambit look like the bad guy]]. Even just trying to stay away from them won't necessarily help; they're likely to take being ignored or avoided as a deliberate snub, and... well, you get the picture.

Characters with a hair-trigger temper are generally grumpy to everybody, but they usually have a favorite victim for their rampages -- often a NaiveNewcomer who doesn't understand ''how'' they keep managing to offend the guy. This can be harmful to the victim's health -- while heroic characters generally restrain themselves to verbal abuse, {{Anti Villain}}ous ones can get physically violent, and out-and-out {{Villain}}ous ones may even ''kill'' people for annoying them. However, such characters are essentially bullies -- if someone tougher or higher ranked than them tells them to knock it off, they probably will, at least for the moment. In a FourTemperamentEnsemble, this character is Choleric.

This can obviously have ''[[PayEvilUntoEvil disastrous consequences]]'' though if they let their temper get the better of them [[TemptingFate far too often]]. Expect the victim who has taken too much abuse [[TheDogBitesBack to suddenly snap in front]] of them with [[UnstoppableRage sudden and alarming reversal of roles]], where the abuser's rage [[BewareTheQuietOnes now pales in comparison to their victims]].

The real life disorder associated with this trope is [[http://en.wikipedia.org/wiki/Intermittent_explosive_disorder Intermittent Explosive Disorder]].

Compare DramaQueen (who acts dramatic at the drop of a hat).

Contrast ExtremeDoormat (who will not respond angrily to ''anything''), PassiveAggressiveKombat, RageBreakingPoint. The particularly psychotic examples almost always overlap with AxCrazy. [[HairTriggerExplosive Doesn't blow up too]], unfortunately.

!!Examples:

[[folder:Advertising]]
* A Snickers ad had a guy turn into JoePesci who blew up at every single comment when he was hungry.
[[/folder]]

[[folder:Anime and Manga]]
* ''Manga/{{Bleach}}'':
** Mayuri Kurotsuchi, the unhinged MadScientist, has something of a hair-trigger temper. This was extremely prevalent in his early appearances, where he flew off the handle at the most minute of provocations, [[KickTheDog which he often took out on his daughter]]. He ''has'' chilled out significantly since then, however, and while he is still [[JerkAss callous]] and easily annoyed, [[PokeThePoodle he handles it a lot better]]. The running joke in the fandom is that Ichigo's group broke into Soul Society on one of Mayuri's bad days. This is made even funnier later on when Mayuri offers only a complaint when Ichigo dares refer to him without rank or honorifics: the other captains comment that Mayuri must be in an excellent mood to let Ichigo off so lightly. Mayuri's good mood does promptly vanish a short while later when Ichigo compares him to Urahara. Even a good day can't stop Mayuri's temper triggering to ''that'' accusation.
** [[DrillSergeantNasty Kensei Muguruma's]] personality. When first meeting the Vizards, Orihime nervously asked where the bathroom was. Love and Lisa had to restrain him from hurting her out of pure irritation. His method for comforting a child almost killed by hollows was "Smile, dammit!". For extra humour, he is stuck with a lieutenant who happens to be The Ditz meets ManChild, who flits between GenkiGirl and Hair-Trigger Temper over the most minor things (such as sesame-topped rice balls).
** Hiyori Sarugaki hates everyone, and takes offense at nearly anything the other characters say to her. She even once jump-kicked Shinji for literally no reason before telling him that she wasn't going to apologize.
** Byakuya Kuchiki is revealed to have had one in his youth. His grandfather commented that he needed to learn how to control the temper before he could develop his talent. As an adult, he acts like TheStoic but there are very strong hints that he's merely become extremely good at hiding the fact he's still got a short temper.
* Eiri Yuki from ''Manga/{{Gravitation}}'' has this sort of temper with boyfriend Shuichi whenever he's trying to mess with the guy's head. In a slight subversion, however, Shuichi catches on to this ploy pretty quickly. That's not to say that he's any good at defending against it though.
* If you so much as blink around [[SociopathicHero Revy]] in ''Manga/BlackLagoon'', odds are she'll get pissed off enough to fill you with holes.
* ''Manga/DragonBall''
** Chi-Chi...big time.
** Other prominent examples are Bulma, Bad Lunch, Piccolo, Vegeta, Pan (GT), and Gotenks.
** Examples in the villains are Nappa, Freeza and Kid Buu/Super Buu.
* ''LightNovel/TheSlayers'': Lina, Lina, ''Lina...'' insult her appearance (namely her [[ACupAngst small bustline]],) deny her food or money, spill her food, upstage her - any of these warrant either some sort of [[FantasticNuke explosion]], screaming, or physical harm. Two egregious examples are Lina nearly drowning Amelia in a hot spring after Amelia makes a lighthearted joke about [[BreastExpansion growing her bustline]], and Lina nuking an entire restaurant for the owner accidentally stepping on a sardine she was eating (which she ''didn't want in the first place'') in the ColdOpen of ''Slayers Premium.'' While she has always had a short temper, though, later anime productions [[{{Flanderization}} flanderize]] it.
* Hiro Sohma from ''Manga/FruitsBasket'' is a particularly obnoxious version, made even more irritating by his [[DeadpanSnarker monotone delivery.]] Gullible Tohru falls over herself trying to appease him, while most viewers quietly harbor a desire to hit the little brat with something heavy.
** "Black Haru", laid-back Hatsuharu Sohma's hostile split personality, has shown signs of this trope as well, deliberately misconstruing Tohru and the student council's president (though the latter probably deserved it).
* ''Anime/VisionOfEscaflowne'':
** Dilandau Albatou from seems to be a combination between Hair Trigger Temper and a PsychoForHire.
** Dilandau's [[{{Expy}} spiritual successor]] Clair Leonelli, from ''HeatGuyJ'', also possesses a Hair Trigger Temper.
* ''Manga/RanmaOneHalf'':
** Ryoga from can often be this way if he ever finds someone insulting Akane.
--->'''Ryoga''': "NO MAN SHALL INSULT AKANE'S LEGS!"
** Akane Tendo can sometimes come off as this around Ranma Saotome, mainly in the earlier parts of the anime and manga.
* Shinodu from ''UruseiYatsura'' used to be a nice and calm teenage girl. But because of all the wackiness after Lum showed up and stole her boyfriend Ataru, the littlest actions around her can suddenly send her into a blinding rage, which is made worse by the [[PintSizePowerHouse massive strength upgrade]] that goes with it.
* Daigo Ikari from ''Manga/{{Eyeshield 21}}'' will always get angry when someone mentions Ojou High School or its football team, the White Knights, in a bad light; the problem is that every time he hears ''anything'', he's always quick to ''assume the worst''.
** This leads to a running gag that Ikari never actually gets to play in a game until the second time Ojou plays Daimon, at least a dozen games into their season. The reason is because he always attacks someone and gets himself ejected before the game even starts. His teammates try to prevent this by ''binding him with chains''. It doesn't work.
** A giveaway is the fact that his [[MeaningfulName surname]] is a homophone for the Japanese word for anger.
* Switzerland and South Italy of ''Webcomic/AxisPowersHetalia''. So, ''so'' much.
** Bulgaria was believed to be one as well, but this was later {{Jossed}}.
** Belarus as well, to the point of attacking Denmark for making a small comment about how he'd win the costume contest, because it implied that he thought he could beat her darling Russia.
** England definitely counts, too. This becomes more apparent when [[FrenchJerk France]] or [[IdiotHero America]] is around.
* Sousuke from ''LightNovel/FullMetalPanic'' can get this way towards people, mostly if it seems to him like the person is "threatening the wellbeing of" Kaname. Even the most mundane, normal things that people say or do can be misconstrued by him as being a dangerous "threat" that must be eliminated. Justified in that he was raised by the KGB, with a highly suspicious, CrazySurvivalist nature.
* Heiwajima Shizuo of ''LightNovel/{{Durarara}}'' has a hair-trigger temper and [[CharlesAtlasSuperpower monstrous strength]] to go along with it. However, he's aware and ashamed of his violent habits and wants to get "strong enough" to keep a lid on them.
* Naru and Motoko from ''Manga/LoveHina'' start off with this trope, going UpToEleven in the anime, though this happens less often once Keitaro manages to eventually win them over.
* Buggy the Clown of ''Manga/OnePiece'' is an interesting variation, where there is [[BerserkButton only one thing that sets him off]]: Mentioning his red nose. However, he seems to be a bit hard of hearing, and tends to interpret anything you say as an insult to his nose, meaning he effectively has a Hair-Trigger Temper.
** Eustass Kid, to a degree than anything that so much as ''irritates'' him can set him off. His AxCrazy disposition is balanced out by his far more level-headed subordinate Killer.
* Shinobu of ''JunjouRomantica'' often misinterprets even the slightest of things and becomes irrationally angry over them. The fact that he knows he's smarter than everyone else only makes this more apparent.
* [[BigBad Grineed]] from ''Manga/BeetTheVandelBuster'' goes berserk when he's addressed in a casual manner. "Dude, calm down" will make him blow a crater in the ground with the sheer force of his trembling with rage. He constantly soaks himself in sedative resin, because he knows that sort of thing is "Not OK", no matter who you are.
* Manabizaki, the main character of ''{{SWOT}}'', always seems angry and annoyed. He gets pissed at anything he deems which interrupts his study time (which happens a lot), and has a tendency to fly into [[BerserkButton a rage at the slightest provocation]]. The fact that his school is filled with {{delinquents}} doesn't help.
* Maho from ''WanderingSon'' gets mad at everything. Saori is a more mild case, and has tried to change.
* Mio from ''Anime/{{Nichijou}}'' has a tendency to get angry whenever Yuuko or her sister, Yoshino, are around. When she gets angry, [[BerserkButton she]] [[UnstoppableRage gets]] ''[[UnstoppableRage angry]]''.
* ''Manga/{{Inuyasha}}'': [[HotBlooded Inuyasha]] and [[AloofBigBrother Sesshoumaru]] are far more NotSoDifferent than either of them will admit. This includes the short fuse that lights their tempers. Inuyasha is openly grumpy, with a base state of "mildly irritated". This flares up into angry on a regular basis even over trivial things. Sesshoumaru, on the other hand, will flit between TheStoic and TranquilFury, although it would be a mistake to think his temper is more muted than Inuyasha since Sesshoumaru's anger tends to be more lethal than Inuyasha's. [[UltimateBlacksmith Toutousai]] once lampshades this by observing that their identical short tempers makes it very easy to see that they're brothers.
* Yanagin in ''Manga/DailyLivesOfHighSchoolBoys'' maybe a DistaffCounterpart to Hidenori in that they're both bookish, GenreSavvy and a bit of a BigHam--what's different is Yanagin has a hair-trigger temper (and punches out Ikushima a lot in the process).
* HotScientist and KnightTemplarBigBrother Souichi Tatsumi from the BoysLove manga ''Manga/{{Challengers}}'' and ''Manga/TheTyrantFallsInLove'' had viewed every action of his StraightGay lab assistant as a transparent attempt to get him into bed from his AnguishedDeclarationOfLove onwards. His suspicions weren't entirely unfounded, but on the whole Morinaga suffers the brunt of his anger unnecessarily. His [[BigBrotherInstinct overprotective]] and homophobic traits also cause his little brother's boyfriend, Kurokawa, to suffer greatly - on hearing the news that Tomoe's married him in Los Angeles, he threatens to fly over there to murder Kurokawa and single-handedly take down the USA for being so "perverted" as to allow gays to marry in the first place. And it's all PlayedForLaughs.
* ''Manga/{{Naruto}}'':
** Sakura can get like this at times due to her fiery {{Tsundere}} persona.
** Tsunade will think nothing of pounding your face in if she gets pissed off.
** Kakuzu is stated to have one, although it's more of an {{Informed Flaw}}
* Edward Elric from ''Manga/FullmetalAlchemist'' gets angry at loads of things, from people calling him short to being told to drink milk. He gets better as the series goes on, though.
** His master Izumi Curtis, who will throw the Elric brothers into walls at the drop of a hat.
* Knuckles The Echidna from ''Anime/SonicX'' will constantly get extremely angry when someone insults him or makes a sarcastic remark. Mostly, [[VitriolicBestBuds Sonic]] and [[BelligerentSexualTension Rouge]] does the button pushing a whole lot. The [[Franchise/SonicTheHedgehog game continuity]] downplay this, however.
** Amy Rose also qualifies. But this is due to being a {{Tsundere}} with [[MoodSwinger mood swings]] and whenever Sonic has better things to do than to be romantically involved with her. [[{{Flanderization}} This was taken too far as the series progresses]]. As with the Knuckles example above, this is downplayed in the games.
* Tomoe from ''Manga/KamisamaKiss'' is in many ways an {{Expy}} of InuYasha and like him Tomoe is openly grumpy all the time, has a face that always seems to be set to a "mildly irritated" expression and he tends to go ballistic over minor things.
* Hell's Chef from ''GregoryHorrorShow''. You insult his culinary skills? He'll haunt you. You aren't appreciating his dishes (even if it's because you aren't hungry)? He'll haunt you. [[BerserkButton Smoking on his watch]]? '''[[BigFuckingSword RUN]].'''
* The Nitro from ''Manga/{{Toriko}}'' are one of the more dangerous species in the setting, which is a bonafide DeathWorld, because of an unholy combination of vast strength, intelligence, voracity, and very short and violent tempers. They were called "Nitro" because they have temperaments akin to nitroglycerine. [[spoiler:Even the Taste Hermit Chichi, a presumably friendly Nitro who is able and willing to speak to humans, has a pretty short temper.]]
* Kurogane from ''TsubasaReservoirChronicle'''s is an interesting take on this. Normally he is portrayed as a GrumpyBear and PerpetualFrowner but around Fai he flips out regularly, even if Fai doesn't even try to provoke him. Just one look is enough to make Kurogane try to murder him. [[CharacterDevelopment Or at least in the beginning.]] Around Mokona, on the other hand...
[[/folder]]

[[folder: Comic Books]]
* Tina the technical writer in ''ComicStrip/{{Dilbert}}'', who "regards every conversation within her hearing distance as an insult to her occupation and [[StrawFeminist gender]]." She's lightened up considerably in later years, though.
** Alice and her Fist Of Death on the other hand... [[SassySecretary Carol]] later [[http://www.dilbert.com/strips/comic/2013-12-29 calls her out]] on her ComplimentBackfire tendency.
* There is ''absolutely no way'' of knowing whether saying something to TheJoker will result in him laughing or killing you, horribly and violently. Or doing both. You're on slightly safer ground with MarxBrothers quotes.
** In one arc, Robin escaped the Joker by deliberately mis-identifying the source of just such a quote; the Joker thought it was more important to argue and convince him he was wrong than to just go ahead and kill him, which was the whole reason he'd captured him in the first place.
* Superboy-Prime, while a moron, is terrifying because he ''will'' fly off the handle and start trying to destroy everything in sight at the slightest provocation. The reason this is terrifying is because he's as strong as [[PhysicalGod Silver Age Superman]].
* In ''GIJoe'', bomb specialist Short Fuze's codename doesn't come from his explosive expertise, but his explosive temper.
* Johnny C, from ''JohnnyTheHomicidalManiac''. In addition to being AxCrazy, Johnny has killed dozens of people for one person's poor choice of words. He's wacky like that.
** Great, now ''you're'' dead.
* Mustafa / "Staffie" from ''ComicBook/{{Mingamanga}}''.
* Honestly, TheIncredibleHulk should be the poster boy for this trope. His entire existence basically hinges on this concept, and even if you do manage to get him to a calm state, he often assumes that someone is stealth insulting him or trying to tell him what to do, which either causes him to leave in a huff or just attempt to smash your ass.
* Namor the {{Sub-mariner}}.
* Monica from Brazilian comic ''MonicasGang''. Just a slight provocation might earn a [[ImprobableWeaponUser plush bunny]] beating.
* In the German comic ''ComicBook/{{Werner}}'': The "Präsi" (president) of the local biker club. %% This entry was added automatically by FELH2. In case the wording doesn't make sense, rewrite it as you like, remove this comment and tell this troper.
* This is the defining trait of Blowtop in ''ComicStrip/DickTracy''.
* ''ComicStrip/TheFarSide'' had a lot of cartoons like this. For instance, one early strip showed an angry man holding a smoking shotgun, having killed two people with it, while his wife behind him angrily says, "That settles it, Carl! From now on, you're only getting decaffeinated coffee!"
[[/folder]]

[[folder:Fan Fic]]

* Barricade from ''[[http://www.tfw2005.com/boards/transformers-fan-fiction/828948-transformers-meta.html Transformers Meta]]'' possesses this.
** For example, he doesn't hesitate to scream at his commander whenever he disagrees with him.
** You can find him standing in corners, glaring at whoever's around him.
** He openly admits [[HatesEveryoneEqually that he hates everybody]].
* Kaji, of the ''DragonballZ'' fanfiction ''Fanfic/HonorTrip''. His default personality is annoyed, and his moods only get less friendly. Of course, [[SurroundedByIdiots he has to constantly deal with Hufeh's shenanigans]], which would test anyone's patience.
* In PrisonIslandBreak, Shadow the Hedgehog can go from zero to psycho at the drop of a hat.
--> '''Sonic:''' "Boy, Shadow sure gets antsy when you squeeze the toothpaste from the wrong end."
* In the ''FanFic/TamersForeverSeries'', it is ''very'' easy to piss off Rika.
** This is [[LampshadedTrope Lampshaded]] at one point.
-->'''Takato''': ''I thought you were mad at me?''
-->'''Rika''': ''Do you think I'm the kind of person who gets mad at silly things like that?''
-->'''Takato''': ''Ummm�''
-->'''Ruki''': '''''Ladies and Gentlemen, we have a dilemma here!'''''
-->'''Takato''': ''Ah�Rika, do you want the right answer or the nice answer?''
--> ''*THWACK!!*''
-->'''Takato''': ''"Ow!"''
** [[spoiler: As the Avatar of Wrath, Jeri makes Rika look like a pacifist in comparison.]]
* Absolutely everyone in ''Fanfic/KnowledgeIsPower'' flies off the handle at the slightest provocation. The only real difference between the heroes and the villains is that the former get away with it and the latter just shoot themselves in the foot.
* ''Fanfic/WeirdIncidentShit'': [[Webcomic/ProblemSleuth Problem Sleuth]] can tell that [[VideoGame/{{Touhou}} Reimu Hakurei]] has one.
** He's right- if you try to challenge her to a fight, you get a Bad End.
[[/folder]]

[[folder:Films -- Animated]]
* Yao from ''Disney/{{Mulan}}''.
* Also Hades from Disney/Hercules.
* ''WesternAnimation/TheLEGOMovie'': God forbid you don't fail Lord Business, even in the slightest way possible. If he doesn't have everything his way, he will stop at nothing to exact his murderous wrath and get everything back in order. Nobody crosses him and survives, mostly because of how unpredictable and single-minded he is. [[spoiler: GCBC seems to be the victim of this a lot, at one point being forced to Kragle his parents after he failed to capture the Special and the Piece of Resistance, Good Cop having his face erased for disloyalty and then being abandoned in the Think Tank, which holds the Master Builders, set to self-destruct, when he is no longer of use]].
[[/folder]]

[[folder:Films -- Live-Action]]
* Creator/JoePesci specialized in playing this type, mostly through his work with Creator/MartinScorsese. In fact, the trope was once named "The Pesci". In RealLife, though, Pesci is a sterling example of MeanCharacterNiceActor.
** [[TropeCodifier The biggest inspiration for the trope]] is Tommy [=DeVito=] from ''Film/{{Goodfellas}}'', who has a vicious temper borne from a [[InferioritySuperiorityComplex need to prove he's the world's biggest badass]], and can snap at the slightest provocation. His usual recourse against an insult to his person is to murder the offender, regardless of whether they are a lowly busboy or a mob boss. His instability ultimately causes problems for him later in his career. Interestingly, [=DeVito=] is very aware of his reputation. In one scene, he feigns offense at a harmless compliment to toy with his friends. The hardened gangsters not only believe that his rage is real, but they're terrified of him. [[spoiler:Tommy's temper and instability eventually get him killed when he kills a made man, which you do NOT do in the mob without a sitdown and an okay from the boss]].
** Nicky Santoro in ''{{Casino}}'' is a {{subversion}}; he is less capricious and unruly than Tommy [=DeVito=], being unlikely to kill on a whim, but is shown using extreme violence in a much more calculated fashion. Also, Nicky shows [[EvenEvilHasStandards a bit more respect]] for his friends than Tommy would. He even gets a PetTheDog moment with his son and another where he gives money to one of his mooks to help support his kids after the mook gambled all his money away. While Tommy has a raging InferioritySuperiorityComplex driving his violence, Nicky has no such problem with his self esteem and uses violence to gain money and maintain power.
** Pesci's earliest example is Joey [=LaMotta=] in ''RagingBull''. [=LaMotta=] spends most of the movie getting bullied by his big brother, but takes the time to have at least one Pesci freak-out.
** In ''Film/{{JFK}}'', Pesci plays an ex-CIA agent named David Ferrie who is so paranoid about the government agents who are going to kill him if anyone starts poking around JFK's assassination, that Garrison's mere hint that he wants to talk to Ferrie about something private throws Ferrie into a psychotically paranoid panic that renders him incapable of doing anything but [[ClusterFBomb drop the F-Bomb]].
** Pesci's character from ''Film/EightHeadsInADuffelBag'' is basically a more subdued version Tommy from ''Goodfellas'' - who has all the hair trigger of the other character but is smart enough to know that shooting everything in sight just because it's annoying him is a bad idea - he makes do by making very sincere promises to kill everyone later instead. In the end, however, [[HeelFaceTurn he decides against it.]]
** And of course, there's Leo Getz's penchant for the epic ClusterFBomb in the ''LethalWeapon'' series.
** Pesci's character Harry in the first two ''Film/HomeAlone'' movies probably also counts, though his outbursts consist of mutterings of [[{{Angrish}} "ratcha fratcha"]] instead of intelligible profanities.
* Don Logan from ''Film/SexyBeast'' is described by actor Ben Kingsley as the unhappiest man in the world, Logan is clearly hated even by his friends and colleagues. Upon arriving in Spain, he is given a cold and awkward reception by his old friends, who are clearly terrified of him. Once they go against his wishes, however, he launches into a nearly unending tirade of abuse and self-pity, painting their every action is a personal affront to him. After he [[spoiler:is ultimately killed, his boss doesn't even bother taking revenge for the murder, since he didn't like him]].
* Annie Wilkes from the film ''Film/{{Misery}}'' is a frightening and [[{{Yandere}} demented]] example of a woman with a Hair-Trigger Temper turned UpToEleven, all the way to AxCrazy StalkerWithACrush. The 'hobbling' scene gives testament to this, and even throws in a WhyDidYouMakeMeHitYou. The scene is even more traumatic in the book, thanks to Annie's [[AnAxeToGrind choice of weapon]]. The movie version is a case of PragmaticAdaptation.
* Francis Begbie from ''Literature/{{Trainspotting}}''. He picks fights for disturbingly minor provocations, including one incident where he blamed a man eating chips of spoiling his pool shot. However, Begbie also intentionally provokes fights for no other reason than that he's addicted to violence and mayhem. In the book, Begbie is described as a large and imposing man, but director Creator/DannyBoyle decided to imply a NapoleonComplex by casting the fairly short RobertCarlyle.
* Albert Spica from ''Film/TheCookTheThiefHisWifeAndHerLover''. He holds court at his swanky restaurant every night, pretending to be sophisticated while he threatens and assaults anyone who even slightly annoys him. This is made more gruesome by the fact that he tends to force-feed his victims inedible objects.
* Cody Jarett from ''Film/WhiteHeat'' is another iconic example of a Hair Trigger Temper.
* Captain Byron Hadley from ''Film/TheShawshankRedemption'' is an angry, amoral man who constantly swears and attacks people in almost every scene that he is in. In the beginning of the film, he brutally beats a prisoner to death simply for crying because it was his first night in prison. He ultimately reveals himself as a coward by "sobbing like a little girl" when he's finally brought to justice and sent to Shawshank as an inmate; [[ThisIsGonnaSuck it's not at all hard to understand why]].
* Doyle Hargrave in ''Film/SlingBlade''. Luckily, he gets his comeuppance at the end of the film. Mm-hmm.
* Kevin "O-Dog" from ''Film/MenaceIISociety''. Imagine a black, slightly more trigger-happy version of Tommy [=DeVito=] from ''Goodfellas'' and you have O-Dog. In opening scene, O-Dog and the main character are in a liquor store and suspiciously watched by the proprietors. After they pay for their drinks, which they have already started drinking, the cashier tells O-Dog that he pities his mother. O-Dog responds by killing him and his wife and stealing the surveillance tape, which he proudly plays for his friends.
* Conspiracy Brother in ''Film/UndercoverBrother'' flies off on overly-paranoid, outraged (and often absurdly ill-informed) TheMan-is-keeping-me-down rants on the flimsiest of provocations. Even someone cheerfully saying "Hi, Conspiracy Brother!" in greeting is guaranteed to send him spiraling off into a rant about how everyone assumes that black people spend all their time getting high.
-->"Brother, when you get a minute, could I get a list of the words that trigger these fits?"
** Conspiracy Brother doth protest too much. He actually ''does'' spend a lot of his time smoking pot. His paranoia is in no small amount due to this.
* Walter Sobchak (John Goodman) in ''Film/TheBigLebowski'' is an unbalanced ex-Vietnam soldier with serious rage issues who will pull a gun over a bowling league dispute.
-->"[[PunctuatedForEmphasis This is bowling]]! [[MemeticMutation There are]] ''[[MemeticMutation rules]]''! ''[[SeriousBusiness MARK IT ZERO]]!''
** Interestingly, among the cut scenes was a discussion revealing that Walter was never actually in 'Nam; his habit of bringing it up is just a shallow attempt to excuse his own issues since the number of people likely to actually contest that point in the face of Walter losing his shit is almost nil (basically just Jeff Lebowski).
* In the film ''Film/PrimalFear'', a plot point is that Aaron Stampler, a stuttering boy accused of brutally murdering an abusive archbishop, when under enough stress, switches into another sociopathic persona named Roy, a textbook example of this trope. At the very end of the movie, it's revealed that [[spoiler:Aaron not only murdered the archbishop and another girl, but he had made up the Aaron personality to win the case, establishing himself as a ManipulativeBastard]].
* Amon Göth in ''Film/SchindlersList''. TruthInTelevision.
* Harvey Keitel as Feraud in ''Film/TheDuelists''.
* Creator/RobertDowneyJr in ''Film/DueDate'', whose character's outburst gets him kicked off the plane and placed on the "no-fly" list, kicking off the movie plot. His wife even mentions his temper.
* Tugger from ''Film/{{Brick}}'' is high-class muscle and the second in command of "The Pin". His tendency to fly into a blind rage at the slightest provocation makes him more trouble than he's worth, however, and causes numerous serious problems throughout the movie.
* [[FieryRedhead Cherish]] (Creator/AliciaWitt) in ''Film/CecilBDemented'': always seems to be either horny, pissed off, or both; at one point, shoots up a popcorn machine because [[SeriousBusiness the popcorn is cooked in coconut oil]].
* Frank Booth from ''Film/BlueVelvet'' takes this trope to truly disturbing levels. He'll get extremely angry and start yelling and cussing (although he does [[ClusterFBomb that]] pretty much all of the time away), if not get outright violent over even the slightest thing he deems out-of-tune, such as looking at him or not, or not bringing him his beer right away. This alone makes him an extremely unsettling and terrifying individual to deal with.
* In ''Film/PainAndGain'' both Daniel and Paul snap at things that seem very insignificant in hindsight. Paul regrets this, while Daniel seems to embrace it. It seems a lot like typical steroid aggression.
* Mulligan in ''[[Film/{{Underworld1927}} Underworld (1927)]]'' is one hot-tempered gangster.
* Downplayed with Wolverine in the ''Film/XMen'' films, but still present.
* Slade in the Western comedy ''Film/TheGreatBankRobbery''; his TooDumbToLive sidekick gets gunned down after being unable to shut up about this very aspect of the man's character.

* The Serpent Queen, a human woman whose head was magically transformed into that of a serpent, from the FightingFantasy gamebooks possesses such a temper, having murdered a number of the retainers provided to her by Azzur, the lord of Port Blacksand.

* Fëanor in TheSilmarillion.
** [[ItRunsInTheFamily And his seven sons.]]
* In the 1988 children's literature book ''Literature/{{Matilda}}'' there is Miss Trunchbull.
* ''Literature/TheHagakure'', a 18th century Japanese treatise on samurai and their virtues, ''suggests'' Hair-Trigger Temper as highly commendable lifestyle for samurai.
* A character known only as The Kid from the extended edition of Creator/StephenKing's ''Literature/TheStand''. He starts out with fairly clear Berserk Buttons, which the Trashcan Man avoids setting off to survive, but his insanity becomes more apparent as the story goes on. It's clear that, [[spoiler:if he hadn't been killed]], he would have found an excuse to kill the Trashcan Man no matter what he did.
** Another King instance: Wilma in ''Literature/NeedfulThings''.
** And another: Roland [=LeBay=] in ''Literature/{{Christine}}''.
* Francis Begbie in ''Literature/{{Trainspotting}}''. In the book version, Renton clearly outlines a number of Begbie's fantasies that his friends must indulge for their own safety. He says, "The trick was tae discreetly indulge him, without being seen as an obvious crawling suck-up." Begbie gets worse in the sequel, ''Porno'', when he sees a "beast" (paedophile) in a pub, and proceeds to beat him to death. [[spoiler:Spud also attempts to claim life insurance money for his family by getting Begbie to do the same to him]].
* Hotspur in the Literature/FloraSegunda novels. Among other things, he came ''this close'' to shooting the Warlord for groping Flora.
* Literature/AnitaBlake. She regularly has to clamp down on her "seething emotions"--even if it's because someone has pointed out a *gasp* possible flaw in her plan.
* The Gillian Key books are full of this--she's a very grumpy lady.
* Literature/HarryPotter, but only in ''[[Literature/HarryPotterAndTheOrderOfThePhoenix Order of the Phoenix]]''. Fans refer to Harry in this book as "CAPSLOCK!Harry", for reasons obvious to those who have read it.
** [[DarkActionGirl Bellatrix Lestrange]] spends most of her time in the books either [[KickTheDog evilly taunting people]] or [[LargeHam screaming her head off in rage]]. She tends to kill people in either state.
** Voldemort's Hair-Trigger Temper frightens even Bellatrix. He can go from [[DeadpanSnarker quietly sardonic]] to AxeCrazy within a second.
** Uncle Vernon has one bordering on inverse EverythingIsRacist levels regarding magic, to the point where he flips his shit at Harry in ''Chamber of Secrets'' for trying to give Dudley a lesson in politeness (ItMakesSenseInContext).
* Opal Koboi from ''Literature/ArtemisFowl'' is as bad as Voldemort in this department. Her mood-swings will give you whiplash.
* From Literature/ASongOfIceAndFire, the Mountain, Ser Gregor Clegane, snaps at the slightest provocation or perceived insult, and being over seven feet tall and wielding a greatsword one handed, carnage generally ensues. When he loses a jousting tournament due to a misbehaving horse, he ''decapitates'' said horse in a blind rage and attacks his celebrating opponent (and his own brother when he attempts to break up the attack), only stopping when ordered to by the King. This is only a mild example.
** He is given SOMETHING of an excuse in the suggestion that he constantly suffers from unfathomably painful migraine headaches (perhaps due to whatever twist of genetics made him so big and strong), to the point where he constantly has to imbibe the in-universe painkiller 'Milk of the poppy'. Doesn't make him any less dangerous, though.
* In ''Literature/TheDresdenFiles'', Harry develops one of these after the events of ''Literature/DeathMasks''. As the series progresses he gets easier and easier to anger, reaching a point where an outburst of stubbornness from his apprentice results in him blowing up a trashcan with a bolt of fire in sheer frustration. He eventually realizes that this is because [[spoiler: of [[FallenAngel Lasciel]]'s influence on his mind.]]
** [[spoiler:Lasciel later vacates his brain, only to be replaced by the Winter Mantle, which is even worse.]]
* Literature/SisterhoodSeries by Creator/FernMichaels: Kathryn Lucas and Maggie Spritzer sure have these kinds of tempers. Their friends can only live with it.
* Visser Three in ''Literature/{{Animorphs}}''. All the time.
* Vlad "The Impaler" in ''Literature/CountAndCountess''.
* Chauntecleer in ''Literature/TheBookOfTheDunCow'' is a heroic example, his short temper making him VitriolicBestBuds with the self-hating but extremely loyal Mundo Cani Dog, who he uses as a doormat and insults creatively. It also makes him prone to especially bad {{Heroic BSOD}}s. He is also devoted to his wife Pertelote and his three sons.
* Literature/SkulduggeryPleasant, although it tends to be TranquilFury in his case.
* Prakash from ''Literature/KillDecision'' has this.
* Captain Zuccho from ''Literature/{{Incompetence}}''. He especially dislikes the suggestion that he try to calm down.
* Stig, of ''Literature/{{Brotherband}}''. He will fly off the handle if you say he's like his father (a dishonoured thief), take a dump on his mother, or so much as look at [[FireForgedFriends Hal]] funny. [[spoiler: He manages to tame his temper in order to win brotherband training.]]
* The BigBad of ''Literature/TheQContinuum'', 0. He compresses a community of gaseous beings [[AndIMustScream into an inert mass]] when they repelled his attempts to harness them, destroys an entire solar system just because [[SoreLoser they'd overcome the chaos he and his cohorts had unleashed on them]], and hurls an asteroid at Q's future wife when she tries to convince him to abandon 0.

[[folder: Live-Action TV]]
* ''Series/TheAmandaShow'': Misty Raines from the ShowWithinAShow, "Moody's Point." [[CatchPhrase "You're so hurtful!"]]
* ''Series/TheAmazingRace'':
** ManipulativeEditing and the stressful nature will make it seem like several racers a season have one of these, but Season 14's [[FieryRedhead Jaime Faith Edmondson]], above all others, was infamous for going from calm to a rampaging monster at the drop of a hat.
** Jonathan from season six also became infamous for it, to the point that pretty much all the viewers were genuinely concerned that he was physically abusive to his wife and teammate, and the two received a talking-to from Dr. Phil after the season ended.
* ''Series/{{Angel}}'': Illyria's inhuman stoicism makes it hard to see the explosive, homicidal rage in time to steer clear.
* ''Series/BattlestarGalacticaReimagined'': Saul Tigh. Kara Thrace is just as bad which results in quite a tempestuous relationship between the two. It doesn't help that they're both [[TheAlcoholic alkies]].
* ''Series/BoardwalkEmpire'': [[BrooklynRage Gyp Rosetti]] will kill anyone who insults him. Or who he imagines insulted him. Or anyone who happens to be close by [[OffingTheAnnoyance when he's in a bad mood]]. Combined with his penchant for DisproportionateRetribution, it makes him very dangerous. His temper results in a mob war between himself and Nucky Thompson.
* ''Series/BreakingBad'': Had Tuco, an extremely volatile and paranoid drug dealer who actually takes a liking to Walter because he has the balls to stand up to Tuco and demands that Tuco deals fairly with him. At their first drug deal, Tuco kills one of his own bodyguards for a petty reason and Walter and Jessie realize that it is only a matter of time before Tuco kills them over something equally petty.
* ''Series/{{Community}}'': Chang flies off the handle with little or no provocation.
* ''Series/CurbYourEnthusiasm'': Susie Greene, in spades. Usually combined with ClusterFBomb.
* ''Series/DoctorWho'': Nord, Vandal of the Roads, from the serial ''The Greatest Show in the Galaxy''. Any offer of help is met with threats, as is any request for assistance.
* ''Series/DrakeAndJosh'': Crazy Steve:
** '''YOU TOOK MY ENCHILADAAAAAAAAAAA!!!'''
-->'''Josh:''' You hired a guy named ''[[NamesToRunAwayFromReallyFast Crazy]]'' [[NamesToRunAwayFromReallyFast Steve]]?
* ''Series/{{ER}}'': Dr. Anna DelAmico, who tended to react to every single thing Doug said or did as either a sexist putdown or a comeon. To the point where he could not even call her by her first name without her going on a tear about how he was being chauvinist and patronizing.
* ''Series/FamilyTies'': In the episode "I Never Killed For My Father" from the first season, Steven dreads that his father is coming to visit - so he tries to make a list of "safe" topics to discuss. As it turns out, though, there is no "safe" topic. When he [[CallingTheOldManOut lets his father have it]] at the end, then the two of them manage to reconcile.
* ''Series/FreaksAndGeeks'': Kim Kelly was so sensitive that saying anything to her could strike a nerve and turn her hostile. Her boyfriend Daniel once suggested that she be rational about something, to which she replied, in a hair-trigger fashion: "Are you calling me irrational? Because I'll tear your head off, Daniel. I'll tear it off and I'll throw it over that fence."
* ''Series/HellsKitchen'': Gordon Ramsey. He mostly plays it up because people expect it, but things like disrespect and laziness really do set him off. You get a better feel for his real personality in his British TV shows or the version of ''Master Chef'' with children. But if he's set off expect a chef to be on the Chopping block (as in at risk of being eliminated).
* ''Series/TheHoneymooners'':
** Ralph Kramden is practically volcanic, especially when things don't go his way. He is especially like this towards Alice and Ed Norton, and also towards his [[ObnoxiousInLaws mother-in-law]]. A couple of examples:
** When he overhears his mother-in-law tell Alice the "surprise ending" of a murder mystery, that [[spoiler:it wasn't the uncle, but the husband, who committed the murder]], Ralph shouts at her, "'''You are a BLABBERMOUTH!!!!!!!'''"
** ''{when Ralph and Norton are spending the night together}''
-->'''Ed Norton:''' Ralph, are you sure you don't want a kumquat?
-->'''Ralph Kramden:''' WILL YOU GO TO SLEEP!
* ''Series/TheInspectorLynleyMysteries'': DS Barbara Havers, particularly in the early days. In the pilot, "A Great Deliverance", pretty much every other sentence out of Lynley's mouth enrages her for some reason or other. Occasionally, those reasons are even valid. She [[CharacterDevelopment mellows]] [[ThePowerOfTrust out]] [[ThePowerOfFriendship over]] [[TrueCompanions time]]:
-->'''Lynley''': The woman is a minefield!
* ''Series/{{Justified}}'': Dickie Bennett has a violent, if unreliable temper. Sometimes he can keep his cool no matter what stress he is under, while other times even the least setback will drive him into a rage. Since Dickie's a {{sadist}}ic marijuana dealer who believes that MurderIsTheBestSolution, this can have drastic consequences for anybody he has in his power.
* ''Series/{{Merlin}}'': King Uther.
* ''Series/TheMuppetShow'': Miss Piggy not only has a rotten temper, she's more than likely to karate-chop anyone who sets it off.
* ''Series/{{Oz}}'': Many a character but ''especially'' Claire Howell.
* ''Series/{{Pizza}}'': Everyone, as is standard for Australians. Especially Ronnie McDoggle (credit as 'Ronny McDonny') from Freaky Pizza.
* ''Series/{{Revolution}}'': "[[Recap/RevolutionS1E6SexAndDrugs Sex and Drugs]]" introduces Drexel, a drug lord with this sort of temper. The sight of Miles Matheson showing up on his property makes him angry. Remembering how Miles betraying Monroe sullied Drexel's reputation makes him angry. His poppy fields, which is uses to make heroin, being burned makes him angry. The fact that the people who burned his poppy fields are a family of Irish cops makes him angry. Aaron looking at him funny makes him angry. Miles running off to stop Charlie Matheson from making a big mistake makes him angry. In short, just about everything makes him angry.
* ''Series/SaturdayNightLive'':
** The host of the "Joe Pesci Show" sketches (played by Jim Bruer) regularly beats his guests with a baseball bat and most sketches end with him attacking the camera.
** The real Joe Pesci and Robert De Niro show up in one episode and beat their impersonators senseless, and FrankSinatra (not the real one) had his bodyguards give Joe a good working over.
* ''Series/{{Saxondale}}'': Each episode opens with the titular character attending his prescribed anger management classes. They don't work very well.
* ''Series/{{Scrubs}}'':
** The Janitor warps every word that comes out of J.D's mouth into justification for making the doctor's life a living hell. After spending an eternity trying to placate the ManipulativeBastard, J.D eventually gives up and tries to beat the Janitor at his own game. It's rare that he succeeds.
** Dr. Cox and Jordan also get the Hair-Trigger Temper when the plot demands it. Carla also seems to have played this role at least once per episode since she and Turk got engaged. In fact, most of the ''Scrubs'' characters adopt this trope temporarily at some point.
* ''Series/{{Seinfeld}}'': The doorman, the Soup Nazi, and Frank Costanza.
* ''Series/{{SomeGirls}}'': Holli Vavasour has such a legendary temper, that all her friends run for the hills or watch in helpless resignation when she goes off on some poor sap. She even threw a ''toilet'' out the window during one fit of rage.
** Her [[VitriolicBestBuds friend]] Saz isn't much better, lashing out in rage at anything she even perceives as a slight. She once slammed Holli's head into a table, although that's justified as Holli had accidentally humiliated Saz in front of her crush.
* ''Series/TheThickOfIt'': [[http://www.youtube.com/watch?v=CuBFAp6EmnY&feature=related Malcolm Tucker and Jamie McDonald]] are both possessors of very, very short fuses for anger.
* ''Series/TheWestWing'': Toby Ziegler. Case in point: Margaret runs away from him in fear of his sanity when one day, in an unnaturally good mood, he tells her to "let a smile be your umbrella."
* ''Series/WhoseLineIsItAnyway'': Once parodied this with a game called "What Are You Trying to Say?" where Colin Mochrie and Ryan Stiles played ''two'' people with hair trigger tempers taking each other's comments the wrong way.
* ''Series/TheYoungAndTheRestless'' and ''Series/TheBoldAndTheBeautiful'' Crossover: Sheila Carter could easily take naming rights of this trope home. "What are you. nuts?" "Bitch, I will snap you like a twig. NOBODY MESSES WITH ME, NOBODY!"
* ''[[Series/CmonMidffild C'Mon Midffîld]]'' has Mr Arthur Picton, who is like this to almost everyone, but ''especially'' with the foolish [[BumblingSidekick Wali Tomos]]. His reaction to almost everything Wali suggests is "[[BigWhat BE!?]]".
[[/folder]]

[[folder:Multiple Media]]
* Plenty is said about [[IronicName Master Zen]] from the ''Franchise/{{Noob}}'' franchise knowing that his background story includes ApplianceDefenestration that, [[DeconstructedTrope thanks to an old lady standing under the window at the time]], ended up being AccidentalMurder. What had enraged him was the chronic stupidity of one of his guildmates. Once escaped from jail, his story arc is basically a long string of DisproportionateRetribution. The novels mention him being physically abusive of his hardware before the "incident" while his apperance in a comic flash-back shows him yelling all the time.
[[/folder]]

[[folder:Music]]
* [[http://www.youtube.com/watch?v=gAYL5H46QnQ "I threw it on the ground!"]]
* On Music/TenaciousD's first album, there was a bit where JB karate chops KG for eating his schnitzel. He also loses it and tells KG he's fired for saying that 'inward singing' isn't ''completely'' non-stop.
* Morrisey, full-stop. The man hates everything.
* Eminem drops many a ClusterFBomb.
** Eminem has named his daughter as a particular hair trigger - during their feud, Benzino threatened Hailie's life in a song. Which made things SO MUCH WORSE.
** Or, go ahead. Ask him about either of his parents. (Though given that 'angry Eminem' has subsided, this may no longer be the case.)
* Pete Townshend was known for frequent and intense bouts of anger when recording with TheWho, which fortunately receded just quickly enough to keep everyone from hating him (he was a perfectionist).
* Two verses in "Endless Vacation" by Music/TheRamones have the phrase "hair trigger temper" in them.
[[/folder]]

[[folder:Mythology]]
* The [[JerkAssGods Olympian gods]] from ClassicalMythology are infamous for [[DisproportionateRetribution taking offense at any perceived slight.]] But the worst by far was Poseidon, Zeus' brother and god of the sea and earthquakes. Unlike other gods who confined their tempers to mortals Poseidon would try and take his rage out on his fellow gods for perceived slights. [[TopGod Zeus]] was the only one who could exercise any control over him and even then walked on egg shells around him.
* The sage Durvasa from HinduMythology was feared for taking offense at the slightest perceived disrespect even if none was intended or was done with good reason and using his powers to curse the unfortunate victim. People would call upon any divine favors they had to make him happy or get rid of him as soon as possible.

[[folder:Pinball]]
* Sir Psycho from ''Pinball/MedievalMadness''
[[/folder]]

[[folder: Tabletop Games]]
* This is the clan weakness for the Brujah in ''TabletopGame/VampireTheMasquerade''. As passionate warrior-philosophers turned modern rabble, they have a rather difficult time resisting [[UnstoppableRage Frenzy]] compared to the other clans.
* The "Bad Temper" disadvantage in ''TabletopGame/{{GURPS}}'' is this in a nutshell. Your character's stressed? Make a Will roll to ''not'' lash out at or even physically assault somebody convenient. ("Berserk" is explicitly the next worse form of this and the two can't both be taken together for that reason.)
[[/folder]]

[[folder:Theatre]]
* In Jean Kerr's parody of MikeHammer, "Don Brown's Body" (originally staged as a revue sketch and published in ''Please Don't Eat the Daisies''), Mike maims random strangers for doing things like asking him the time of day. "Like I say--I don't take slop from nobody."
* Katerina from ''Theatre/TheTamingOfTheShrew'' is an iconic example. Petruchio solves her problem by feigning it himself, thereby giving her a taste of her own medicine.
* Theatre/{{Othello}} has one of these. Exploited relentlessly by [[MagnificentBastard Iago]].
* Theatre/{{Hamlet}} as well.
[[/folder]]

[[folder: Video Games]]
* Wigglers from the ''VideoGame/SuperMario'' games are cute, giant caterpillars with flowers on their heads. If you jump on them [[note]]except in ''VideoGame/SuperMarioRPG''[[/note]], they'll get enraged and move faster.
** The Wiggler that appears as a boss in ''VideoGame/SuperMario64'' is also like this: two things he's been confirmed to hate are getting wet and getting stomped on. Other than that, though, [[MinionWithAnFInEvil he's not really that evil]]. [[AttentionDeficitOohShiny He's just greedy for things that shine]].
* In a similar vein, the Scarfies from the ''VideoGame/{{Kirby}}'' games. At first, they're floating puppy heads, but if Kirby tries to eat one, they'll turn into scary cyclops hell-hounds that will chase him until they explode.
* In the first ''VideoGame/DungeonKeeper'' game, the Horned Reaper. When he gets annoyed he'll go berserk and start killing everything in sight. These are a few things that annoy him: Asking him to train. Asking him to work. Asking him to study. Asking him to live with other people. Not feeding him promptly. Not paying him promptly. Allowing him to pray, something that's supposed to make creatures happier. Leaving him on his own to do nothing. It helps if you drop gold on him at regular intervals.
* It's an InformedAbility, given that we never see it happen, but Prosecutor Byrne Faraday in ''Franchise/AceAttorney'' could apparently get very nasty when he got angry over things as small as a detective showing up late to work. In fact, [[spoiler: Prosecutor Faraday blowing up at him and docking his pay is the motive Gumshoe is assigned when he's accused of killing him. Yes, [[BigDamnHeroes that]] [[TheWatson Gumshoe]].]]
** Victor Kudo will use any excuse to throw seeds at people.
* [[ViolentGlaswegian The Demoman]] from ''VideoGame/TeamFortress2'' has one, at least when he's [[InVinoVeritas drunk]].
* In the ''Franchise/{{Pokemon}}'' game series, there is a Fighting-type pig monkey Pokémon called Primeape. The species as a whole will lose their temper as a response to ''anything'' and will chase the cause of their anger until they catch it and ''beat it bloody.''
** Voltorb and Electrode. They both explode literally at anything that angers them. Electrode is the worst of the two, though...there's a reason it's called 'bomb ball'.
*** Guildmaster Wigglytuf seems to subvert this, despite having this reputation in ''VideoGame/PokemonMysteryDungeonExplorers'' (to the extent that his NumberTwo fearfully warns you not to piss him off when you first meet him) despite his apparent personality as ThePollyanna. Then [[DoubleSubversion Double Subverted]] when [[FailureIsTheOnlyOption you fail to bring back a Perfect Apple]] and he [[UnstoppableRage is literally about to blow up up the guild]], prevented only by [[DeceptiveDisciple Team Skull's]] VillainousRescue moment.
* Seems to affect veteran [[RealLife players]] of competitive team based video games. [=MOBA=] games like ''HeroesOfNewerth'' and ''LeagueOfLegends'' have a notoriously [[{{GIFT}} bad community]]. If you are unlucky, every visible mistake you make results in a barrage of "[[NoSocialSkills retard]]" and "[[DrillSergeantNasty nooooob]]" all the way to "[[ForTheEvulz kill yourself irl]]" from your teammates, and god have mercy on you if you tell your team it is your [[SuffersNewbiesPoorly first game]]...
* [[VideoGame/SengokuBasara Mitsunari]] [[NamesToRunAwayFromReallyFast the Dark King]] is pretty moody at the best of times, but enforces the [[OffWithHisHead death sentence]] for every "crime" he encounters, such as, for instance, telling him "no".
* Jack in ''VideoGame/MassEffect2'', and although in most situations according to the backstory she would tear any poor bastard apart for almost any perceived or real slight against her, she luckily keeps to shouting aboard the Normandy.
* Vass in ''FarCry3'' has a temper that turns on a dime from "[[AffablyEvil friendly and kooky]]" to "insane murderous rage" and back again, often during the same conversation. The fact he's the leader of a [[RuthlessModernPirates vicious group of murderers and people-smugglers]] doesn't really improve his victim's chances any.
* Kratos from the ''VideoGame/GodOfWar'' games emotional range tends to be various states of anger. The only exceptions being rare moments of reflection or moments with his family. In flashbacks before any of the games he would fly into rages that scared his daughter and only his wife was willing to stand up to. Anything that irks him or does not immediately go his way switches him to barely controlled rage at best.
[[/folder]]

[[folder: Web Animation]]
* Many flash cartoons feature mass fighting where characters can be provoked even by bumping into them.
* Paul Hammerbro from ''BowsersKingdom'' is notorious for having this. Just don't dent his winged platform or do anything to upset him.
* A literal case for Yang Xiao Long in ''{{WebAnimiation/RWBY}}''. So much as slicing a strand is enough to warrant a greater beating than she would normally deliver.
[[/folder]]

[[folder: Web Comics]]
* ''{{Homestuck}}'': [[TeamDad Karkat Vantas]] tries to come off as the living embodiment of this trope, and he's certainly it verbally... physically, not so much. Also, most of his temperamentality is directed at [[IHatePastMe himself]].
* ''Webcomic/{{Waterworks}}'': Connie, the protagonist, gets angry rather easily... usually [[YouWouldntLikeMeWhenImAngry with destructive results]]; as it turns out, this is pretty much the main reason she has barely any friends, let alone a boyfriend.
* ''Webcomic/TheSenkari'': Freija, though she claims early on she can control her temper, frequently suffers from rather monumental fits of rage, often combined with physical violence.
* Warrick of ''Webcomic/{{Namesake}}'' has this [[spoiler: ever since he removed his heart.]]
* Marissa of ''Webcomic/SturgeonsLaw'' has problems dealing with her anger [[http://sturgeonslaw.net/comic/32-how-many-is-in-minion/ constructively]].
[[/folder]]

[[folder: Web Original]]
* Creator/SeanMalstrom has been known to belittle entire gaming sites in his blog merely because several people in the comments section made offhanded jabs at him. Case in point: a single guy at [=GoNintendo=] named Garfitor [[http://www.gonintendo.com/viewstory.php?id=118989 says]] "Don't worry Darth Vader, Malstrom and his followers are still gonna hate [''VideoGame/MetroidOtherM'']." [[http://seanmalstrom.wordpress.com/2010/03/31/who-is-malstrom-and-his-followers/ This is how Malstrom responded]]. Said [=GoNintendo=] guy [[http://go2.wordpress.com/?id=725X1342&site=seanmalstrom.wordpress.com&url=http%3A%2F%2Fgonintendo.com%2Fviewstory.php%3Fid%3D60983%23comment-218056&sref=http%3A%2F%2Fseanmalstrom.wordpress.com%2F2010%2F04%2F02%2Femail-pachter-calls-vitality-sensor-stupid%2F found Malstrom's response funny]]. [[http://seanmalstrom.wordpress.com/2010/04/02/email-pachter-calls-vitality-sensor-stupid/ This is Malstrom's response to THAT comment]].
* [[Radio/TrueCapitalist Ghost from Radio Grafitti]] is so, SO this trope, in internet radio form. Almost every {{Troll}} that calls him manages to set him off, not to mention anything that isn't capitalism. Doesn't help that he has tons of {{Berserk Button}}s.
* ''Literature/TalesOfMU'':
** Protagonist Mack is prone to [[CuteButCacophonic unnecessary shouting]] and pointless argumentation is a strange hybrid of this and ExtremeDoormat depending on who is around her. [[CharacterDevelopment She has moved away from this as the series goes on]], but still occasionally snaps and yells with little provocation.
** Mack's former roommate Puddy snaps the instant anyone starts to criticize her for her rude, assholish behavior, no matter how nicely they do it.
* [[http://www.youtube.com/watch?v=YersIyzsOpc This video]] portraying a guy who not only goes off like he's possessed because his WoW account is cancelled, but because he is losing a game in another video.
** There are loads of other videos showing him throwing various other temper tantrums over silly things. One particularly {{egregious}} example is when he's auditioning for a company's advertisement and the director happens to use the word "gay" in a sentence while coincidentally gesticulating towards the kid. Cue a HUGE temper outburst, "HE POINTED AT ME WHEN HE SAID GAY!" and breaking everything in the room.
* The infamous ''Halo 2'' video "[[http://www.youtube.com/watch?v=dG42S_PmRs4 Croyt's Anger]]". Among others, he loses it when he gets taken out just after getting a triple kill(even though he's been getting shot the whole time), and the heavens themselves tremble when he gets standbyed.
* How has ''WebVideo/TheAngryVideoGameNerd'' not been mentioned yet? Anger is literally part of his name!
* Several important characters in ''Literature/{{Worm}}'' have temper issues:
** Danny Hebert, the protagonist's father, has a violent temper that [[DefiedTrope he keeps tightly in check]]; his father ''didn't'', and he doesn't want to be like him.
** Bitch is an obvious example, being easily angered and quick to get physical; interestingly, [[spoiler:this is mostly a adaptation she uses because she can't read social cues, like sarcasm]].
** Shadow Stalker also has a violent temper, both in costume and in her civilian identity.
* Creator/AchievementHunter's Michael Jones has a tendency to get very riled up while playing video games (and even has his own series entitled ''Rage Quit''), which can very easily deteriorate into this trope, but other than that he's a perfectly nice guy.
* Yang Xiao Long from ''WebAnimation/{{RWBY}}'' has a ''literal'' HairTriggerTemper. As in, she goes nuts when so much as a strand is messed with. Only in that sense though.
* Literature/LightningDust: Andy regulates his breathing in order to keep his temper under control.
* The ''WebVideo/HitlerRants'' videos mostly revolve around Adolf Hitler flipping his shit at nearly everything, whether it's pop culture or failure of his plans. He also doesn't appreciate stuff in the bunker like Fegelein's antics or Jodl's objections.
[[/folder]]

[[folder: Western Animation]]
* Pesto the pigeon from the "Goodfeathers" segment of ''WesternAnimation/{{Animaniacs}}'' is based on the Tommy character played by Joe Pesci, above. He aims his outbursts mostly at Squit, who never quite figures out that calling Pesto ''anything'' results in his getting beat up. In another case, Pesto has lost his sister's egg, and Bobby reassures him that they'll get it back. Squit agrees with Bobby. Pesto smacks Squit. What'd he do? "Nothing. I just felt like smackin' somebody." (His voice actor was not JoePesci, just Chick Vennera doing a damned good Pesci impression.)
** Taken to an absolute extreme with Katie Kaboom. Imagine the kind of creature that The Hulk would think needs to calm down, or run away from because her transformations are too freaky. That's our Katie.
* Eva from TotalDramaIsland is a good example of this. Pretty much every character is afraid of her (including animals). It isn't helped by the fact that she has SuperStrength.
* Anthony De Martino from ''WesternAnimation/{{Daria}}''.
** Ms. Janet Barch could also be a similar example.
* Coach Buzzcut from ''WesternAnimation/BeavisAndButthead''.
* Denzel Crocker, from ''WesternAnimation/FairlyOddParents''. Even discounting his fairy-triggered BerserkButton, there is ''nothing'' you can say to this guy without him going crazy.
** "If they survive this, then they're FAIRIES! If they don't, I HAVE TENURE!"
*** Of course, HE survived that too. That must mean...HE'S A FAIRY!
*** "Hmm, you're right. HAVE A NICE DAY!!!" *Twitch*
* As a result of drastic NotAsYouKnowThem treatment, the formerly sanguine Silverbolt starts showing a surly hair trigger temper in ''Franchise/{{Transformers}} WesternAnimation/BeastMachines''. Particularly whenever Blackarachnia speaks to him. Explosive outbursts are rare, but he still takes exception to nearly everything.
** Then there are G1 characters Afterburner, Rampage, and Slugfest. Afterburner displays dizzying heights of hysteric anger and rage at the most innocuous comment (though he's ''always'' angry, he tends to need some "setting off" for it to show all that strongly); Rampage is angry all the time except while watching television; and Slugfest, being both stupid and paranoid, is too dim to know when someone ''isn't'' making fun of him and just always reacts with aggression to ''everything''.
*** Also in G1, Galvatron often exhibits this.
* Cotton Hill, from ''WesternAnimation/KingOfTheHill''.
* ''WesternAnimation/{{Futurama}}'''s bit character [[http://futurama.wikia.com/wiki/Roberto Roberto]] has a hair trigger with a hair trigger:
--> '''Roberto:''' "I'm thinking of a number between one and ten, guess it, I kill ya!"
--> '''Bender:''' "Er, 56... ish"
--> '''Roberto:''' "56? 56?! That's all I can think about! I'm gonna kill you you lousy 56ing..."
** '''[[MemeticMutation Windmills do not work that way!!!]]'''
** Malfunctioning Eddie is this. He literally explodes from even the slightest amount of shock or surprise. It doesn't even have to be anger; in "Insane in the Mainframe", when he introduces himself to Fry, Fry responds "We've met before", causing Eddie to scream "[[BigWhat WHAT?!]]" and explode on him.
* [[WesternAnimation/TheSimpsons Homer Simpson]] is a rageaholic. He can't live without rageahol.
* DonaldDuck, naturally.
** Perhaps more so Daisy, Donald is at least usually cranky on a consistant basis. Daisy on the other hand can go from polite and kindly to ''ten times as violent'', sometimes for even pettier reasons than Donald.
* Heloise and Lucius from ''WesternAnimation/JimmyTwoShoes''.
* The Earl of Lemongrab from ''WesternAnimation/AdventureTime.'' Being the angry, screaming result of a science experiment gone horribly wrong, he has quite a few issues to sort out.
* The titular Ren from ''WesternAnimation/TheRenAndStimpyShow''.
* [[MemeticMutation LEMME TELL YA SOMETHIN', TV TROPES]]. [[Franchise/{{Ben 10}} RATH]] IS MAD YOU DIDN'T PUT [[ThirdPersonPerson RATH]] ON HERE ALREADY.
* ''WesternAnimation/BatmanUnderTheRedHood'' has Black Mask, who seems to have two temper settings. Mad, and punch all my henchmen mad. Almost all of his scenes consist of him yelling angrily. An odd exception comes near the end. [[spoiler: After being betrayed and captured by the Joker, he gives a rather deadpan "Can't. trust. no one.]]
* Zuko from ''WesternAnimation/AvatarTheLastAirbender'' has this tendency, especially before [[spoiler: his HeelFaceTurn]]. Quite appropriate for a HotBlooded character with [[PlayingWithFire fire-based]] PersonalityPowers.
** [[MagnificentBitch Azula]], is able to be set off by ''anything'' by the end of the series.
* Nicole, the mother in ''WesternAnimation/TheAmazingWorldOfGumball'', goes from "sweet, caring mother" to "so angry she punches a hole in the wall" at the drop of a hat.
* Fuzzy Lumpkins on ''WesternAnimation/ThePowerpuffGirls'' is ''always'' in a bad mood, but if you ''really'' make him mad, he [[HulkingOut goes berserk]] and lays has the subtlety of dynamite.
* Spike the bulldog from ''WesternAnimation/TomAndJerry''.
* Kyle Broflovski from ''WesternAnimation/SouthPark'' is quite easily pissed off, usually because of something Cartman says or does.
** [[KnightTemplarParent His mom]] [[LikeFatherLikeSon is no better]].
** Cartman falls under this trope as well, and the results usually aren't pretty.
* [[WesternAnimation/LooneyTunes Yosemite Sam]], a song in TheLooneyTunesShow is basically about his temper.
* The Beast of ''Disney/BeautyAndTheBeast'' was this initially, eventually after he warms up to Belle he learns to control his temper.
* ''WesternAnimation/EdEddNEddy'': Eddy and Sarah are most definitely this. Doesn't help that Eddy has NoIndoorVoice whatsoever.
** The episode "Luck of the Ed" has this for Eddy UpToEleven bordering on full-blown insanity when Ed loses [[GettingCrapPastTheRadar the magizines Eddy was hiding from his mom]] and Eddy goes ballistic.
** Even more so in "Little Ed Blue", in which GentleGiant Ed gets a stone in his shoe, making him far more ferocious than Sarah ever was.
* Brian often finds himself triggering this with Quagmire in ''WesternAnimation/FamilyGuy'', who takes offense to nearly any comment Brian directs towards him and erupts in a verbal (and sometimes physical) smackdown. Granted this is not a consistent character trait for Quagmire but provoked more from [[SitcomArchNemesis his hatred for Brian and everything he stands for]].
** Joe too even more so he often lashes out with even the slightest provocation and beats even his friends to a bloody pulp, this is rather jarring because in the early episodes he was very friendly and outgoing and he rarely got upset.
* The titular character on ''WesternAnimation/DanVs'' is this. The slightest thing well set him off. Be it that the ATM charges him 50 cents more than last time causing him to rob a bank, or that Chris won't pick up his phone in the middle of the night to join in on one of his crazy schemes. Most of the times Dan's anger is justified at the end, but even so he will still be set off by minuscule things all the way through, and the fact that the targets of his rage often turn out to deserve it is pretty much a coincidence.
* ''WesternAnimation/LiloAndStitchTheSeries'' has Nani {{Flanderiz|ation}}ed into this.
* Benson from ''WesternAnimation/RegularShow'' is always on the brink of losing it, especially when dealing with his slacker workforce.
* [[WesternAnimation/{{Squidbillies}} Early Cuyler]]: Mad as hell and twice as drunk.
* Superboy from ''WesternAnimation/YoungJustice'' was grown as a clone and thus has no idea how to control his emotions, resulting in this trope. It's played for some laughs when he goes to school for the first time, and Miss Martian has to constantly stop him from attacking everything. By season 2, he's grown out of it, thanks to being mentored by Superman.
* Li'l Gideon has one in ''WesternAnimation/GravityFalls''.
* Jake from ''WesternAnimation/MrBogus'' sometimes had this kind of temper.
* ''TheFlintstones'': Fred Flintstone is known for this.
* [[GrumpyBear Hubert]] [[AbusiveParents "Dad"]] [[JerkAss Test]] from ''WesternAnimation/JohnnyTest'' easily gets mad when Johnny does something irresponsible .
* Rancid Rabbit from ''WesternAnimation/CatDog''
* Nester, his mom and Dan Duck from ''WesternAnimation/ScaredySquirrel''
* [[TheEeyore Mr. Wilter]] from ''WesternAnimation/ChalkZone'' gets pissed off so easy if someone makes a mess in his classroom.
* [[BigBadWannabe Prof. Pamplemoose]] from ''WesternAnimation/{{Sidekick}}
* Trina Riffin from ''WesternAnimation/{{Grojband}}''
* Recurring antagonist [[LittlePeopleAreSurreal Rambamboo]] from ''WesternAnimation/{{Breadwinners}}''.
* ''WesternAnimation/AladdinTheSeries'': In the episode ''The Seven Faces of Genie'', Genie's Anger is this trope personified. And throughout a good majority of the episode, said anger was taken out on [[ButtMonkey Abis Mal]].
-->'''Anger!Genie:''' POINT THAT BEARD AT ME AGAIN, AND I'LL '''''[[DisproportionateRetribution RIP YOUR SPINE OUT]]'''''!!!
* Two-Face's origin story in ''WesternAnimation/BatmanTheAnimatedSeries'' shows that the persona that is Two-Face is called "Big Bad Harv", a subconscious personality that exists within Harvey Dent's mind that represents years and years of repressed anger. The smallest slight can push this side of him into the fore and cause him to lash out, which can happen even if he's on camera or at a public event.
