[[caption-width-right:350:You might still like him, but you're screwed anyway.]]

->'''David Banner:''' Mr. [=McGee=], don't make me angry. You wouldn't like me when I'm angry.
-->-- ''Series/TheIncredibleHulk''

A SuperTrope for when you just don't want to tick off a character. Bad things will happen, which can include:
* AngstNuke: The character explodes destructively out of sheer rage.
* AwakeningTheSleepingGiant: An entire group is roused from its neutrality and is ''not'' happy about it.
* BadMoodAsAnExcuse: When trying to talk out a person who isn't in the mood, only to get lashed out on.
* BerserkButton: When pissing off comes from a specific thing.
* TheBerserker: The character starts mindlessly attacking everything in his path.
* BewareTheNiceOnes: When a particularly nice character ''snaps'' after being messed with one too many times.
* CrouchingMoronHiddenBadass: Triggers superpowers.
* HairTriggerTemper: When it's really hard ''not'' to piss a character off.
* HulkingOut: Triggers InvoluntaryShapeshifting. [[CatchPhrase HULK SMASH!]].
* PersonOfMassDestruction: For characters who are at risk for becoming a WoobieDestroyerOfWorlds.
* RelativeButton: The character gets pissed when his or her family is hurt or killed.
* RageBreakingPoint: The character doesn't want to get angry, but eventually loses it.
* ThisIsUnforgivable: What the character may be thinking.
* TranquilFury: The character's ready to tear you apart in a seemingly calm manner.
* UnstoppableRage: The character gets righteously pissed and pulls out all the stops to take you down.

It doesn't matter if the character is the hero, villain, supporting character, or bystander. Just don't piss off this character if you don't want big trouble.

PsychoactivePowers can sometimes involve this. Related to EmotionalPowers.

[[folder: Anime and Manga ]]

* ''Anime/DragonBallZ''
** Son Gohan. He is a happy-good-lucky kid and a dorky teenager. When he's mad and his friends and family are in danger, however, he ''will'' tear you a new one.
** His father, Goku, is almost as bad, especially when he was kid. He is fun loving, goofy, and playful even when he's fighting. When upset or angry, he tends to go on killing rages as a kid, something the Red Ribbon Army and King Piccolo found out. Frieza also learns what happen when Goku is angry and it isn't pretty.
** Piccolo is a [[TheStoic stoic]] most of the time. However, hurt, threatened to hurt, or, god forbid, kill Gohan and you really won't like him as he slice you in two as Babidi learned.
** Chichi. She makes the Saiyan squirm, and she's just a human...with a [[FryingPanOfDoom pan.]]
* Shizuo Heiwajima from ''Literature/{{Durarara}}''. Granted, it's generally in good form not to piss off people with SuperStrength in general, but this one is ''especially'' [[HairTriggerTemper easy to set off]]. He's basically the Hulk, except that he doesn't get big and green to give a visual cue to his anger-fueled super strength.
* Shinigami in ''Manga/SoulEater'', and his son Kid on a smaller scale. Yes, other characters cause greater damage than usual when angered, but these two spread it around more, whether to pyramids or an entire city.
* Manga/{{Naruto}} can give even the Trope Namer himself a run for his money in this department in his kyuubi forms.
* [[TheBerserker Natsu]] of ''Manga/FairyTail'' is an example of this, as the ''[[BerserkButton flame of emotion]]'' that is the source of power for his Dragon Slayer magic causes him to actually become stronger the angrier he gets.
** Erza Scarlet is another person you don't want to piss off.
** [[spoiler:[[TheDreaded Zeref]],]] too, even moreso. He may be a self-hating, emotional wreck who has some ''major'' guilt issues (and with good reason), but if you actually manage to anger him - say, by [[spoiler:forcing him to come out of his self-imposed exile and openly stating you want to use him to create a mage utopia]] - you'll see exactly [[CurbStompBattle how]] [[InstantDeathRadius he]] [[PersonOfMassDestruction earned]] [[OneHitKill his]] [[WalkingWasteland reputation]].
** [[DragonInChief Mard]] [[OurDemonsAreDifferent Geer]] of [[DarkIsEvil Tartaros]] normally comes across as TheStoic with an ever-present PsychoticSmirk across his [[{{Bishonen}} handsome]] face...but when Natsu, Sting and Rogue actually manage to give him some slight trouble, along with delaying of his plans and destruction of the Tartaros guild building, he finally decides to delve into some NotSoStoic territory...and gives one [[NightmareFace hell]] of a SlasherSmile to complete it, stating he hasn't felt angry in ''years''. [[CurbStompBattle Then he]] {{No Sell}}s [[CurbStompBattle everything they can throw at him while kicking their asses]].
* Yuuri from ''LightNovel/KyoKaraMaoh'' is [[AllLovingHero as nice as they come]]. However [[BewareTheNiceOnes if you start hurting innocent people or those close to him...]]
* Misty's Psyduck in ''Anime/{{Pokemon}}'' may count. It can only use its incredible Psychic attacks when it has a bad headache. (Which ''usually'' is a result of it becoming angry.)
* Luffy, from ''Manga/OnePiece'', is usually a happy-go-lucky type of guy, but if you so much as dare to hurt any of those he cares for, [[BewareTheNiceOnes you better]] [[BerserkButton have your]] [[DontMakeMeDestroyYou testament ready]].
** [[PersonOfMassDestruction Whitebeard]] is a much straighter example. He might be jovial with conducting with fellow rival pirates and Marines, but you dare to nab/[[spoiler:kill]] ANY of his crew, you'd better rest in peace. [[spoiler:Akainu found it the... ehm easier way.]]
* Setsuna, from ''Manga/MahouSenseiNegima'', is a quiet and polite girl who prefers to stay in the background. Usually, she's really calm and composed even in the heat of battle. But don't, just don't you dare harming [[LesYay Konoka]] unless you want her to butcher you in split-seconds.
* Three words to be feared by ANYONE who [[MamaBear endangers her little boy]]: [[Anime/NeonGenesisEvangelion Evangelion Unit 01]].
* In ''{{Manga/Bleach}}'', people would rather take on Yamamoto's bankai than piss off Captain Unohana. Considering her usual kind personality, it's mostly played for laughs. [[spoiler: As it turns out, she's completely psychotic and the worst criminal in the history of Soul Society. Yeah, that's not a good idea.]]
* In ''{Manga/FullMetalAlchemist}'', Roy Mustang, who is Colonel of the Central army, is quite a ladykiller, TheDitz and sometimes very weird. But.... if you hurt a hair of his subordinates, well... there is a reason he's called the Hero of Ishbal.
* From ''Anime/{{Monster}}'', we have [[spoiler: Wolfgang Grimmer, who drew inspiration for his split-personality]] from [[TheIncredibleHulk The Magnificent Steiner]].
* Vash the Stampede from ''Manga/{{Trigun}}''. He is an adorable goofball most of the time, but when he's really mad, he can throw a NoHoldsBarredBeatdown.
* Meliodas from ''Manga/TheSevenDeadlySins''. He's a small, cheerful little pervert, and a pacifist by nature. However, there is a reason that out of his group, his [[SevenDeadlySins sin]] is wrath.
* ''Anime/SandsOfDestruction'' is full of people who are normally nice (or at least not murderous) but downright psychotic when angered. Both female main characters, Morte and Rhi'a, have {{Hair Trigger Temper}}s. [[spoiler:Once Kyrie Awakens, threatening to harm Morte - which is pretty much the only thing that gets a rise out of him, as he's so gentle otherwise - becomes ''extremely'' hazardous to your health.]]
** In one of the last episodes, Kyrie pleads with Morte not to fight Rhi'a because "that girl is really scary when she gets mad." Kyrie, which of the two were you talking to again?
* ''VisualNovel/UminekoNoNakuKoroNi'' Bernkastel learned it the bad way after [[spoiler: mocking about Lambdadelta's death in front of Battler and pissing him off to the point he gave her the beatdown of her life]].
* Any of the Inner Senshi from ''Franchise/SailorMoon'' can be dangerous when pushed, especially Minako Aino/Sailor Venus, the petite, light-hearted jokester who acts like a ditz. When Tiger's Eye and Hawk's Eye rightly accused Mina of two-timing them and subjected her to a MindRape that caused most victims to faint from exhaustion and agony (including other Senshi), she not only managed to stay conscious, she got angry enough to tear herself out of metal binds, transformed, and sent them running for their lives with an rage-fueled attack. In the manga, when she saw [[{{Protectorate}} Sailor Moon]] being strangled by Queen Beryl's hair, she gave Beryl a DeathGlare, and ran her through with a poison-infused {{BFS}} that is tougher than diamond.


[[folder: Comic Books ]]

* [[TropeNamers Named]] after Creator/MarvelComics's Bruce Banner (a.k.a. the Comicbook/IncredibleHulk), who uses this line to warn people of his HulkingOut ability. [[TemptingFate It doesn't always work.]]
** His daughter Lyra is actually an inversion. Having been engineered to get 'weaker' the angrier she gets as a means of control, Lyra is the one Hulk you 'would' like when she is angry.
* {{Superman}} is one of the nicest guys in the universe. But if someone gets him angry, they find out just how powerful he really is. It says a lot about SelfDemonstrating/LexLuthor that he intentionally does things ''[[{{Troll}} just to piss Superman off]]''.
** Spider-Man has a less powerful variant of the same. Normally, he's nice, friendly, and the worse he'll do is embarrass you a little. But heaven help you if you've hurt someone he loves. You'll need it. The way you can tell that Spidey is really angry is when he ''[[TranquilFury stops talking]]''.
* Also, almost any character from Marvel Universe wearing a symbiote qualifies - one of the most prominent examples would be [[{{Comicbook/Venom}} Flash "Agent Venom" Thompson]]. When he's in control, he's just heroic by-the-book soldier, who often ignores his current mission in order to protect innocents. Get him angry (or worse - [[BerserkButton hurt those innocents]]), and he'll break your bones, scare you to death, and ''then'' [[IAmAHumanitarian bite your head off]].
* Despite his codename of "Hulkling", Teddy Altman of the YoungAvengers is one of the kindest, most even-tempered guys you'll ever meet; he's even described as being "all sweetheart". Of course, that's assuming you don't threaten his boyfriend, Billy Kaplan. Teddy outright pulled this trope on ''ComicBook/CaptainAmerica'' in Billy's defense.
-->'''Teddy:''' Captain, I understand you're concerned about Billy['s powers]. But if anything happens to him... your primary concern should be ''me''.


[[folder: Film ]]

* ''Film/CitySlickers'', when Curly is being buried. The cook can only think of ''"Lord, we give you Curly. Try not to piss him off."'' as a eulogy.
* Making Franchise/{{Godzilla}} angry is a very, ''very'', '''VERY''' bad idea. Doing so will result in a major city (often Tokyo) being destroyed.
* ''Film/TheRockyHorrorPictureShow'': It's a bad idea to anger [[Creator/TimCurry Dr. Frank N Furter]]. Eddie and [[strike:Janet Weiss]] [[FanNickname SLUT!]] had to learn this the hard way.
* The documentary (read: hour-long advertisement) available on the Extended Edition [=DVD=] for ''Film/{{Underworld}}'' featured a self-proclaimed werewolf who named this trope exactly.
* The 2008 ''Film/TheIncredibleHulk'' film. Bruce Banner butchers his catchphrase by way of a bad translation (he accidentally says "hungry" instead of "angry") and proceeds to fight as normal. In the novelization, he says it to two college girls who just laugh at him, since the phrase is full of {{Narm}}. However, the film did also have a variation on the phrase which was pretty good.
--> "There are aspects of my personality that I can't control, and when I lose control, it's very dangerous to be around me."
* ''Film/{{The Avengers|2012}}'' has an interesting subversion. Tony and Bruce have an entire subplot that consists of Tony trying to convince Bruce that being the Hulk is a "terrible privilege" rather than a curse. Bruce disagrees, and keeps insisting that he doesn't want to Hulk out, not even to help the Avengers fight Loki, because he can't control it. The end of their scene in the laboratory features what could be interpreted as a loose variation of the original line.
-->'''Tony:''' I guess we'll find out.\\
'''Bruce:''' You might not like that very much.\\
'''Tony:''' Yeah, and you just might.\\
(''later, after Bruce accepts his situation'')\\
'''Steve:''' Dr. Banner? Now might be a really good time for you to get angry.\\
'''Bruce:''' That's my secret, Cap. I'm ''always'' [[TranquilFury angry]].
* ''WesternAnimation/PussInBoots'': "Tsk, tsk, tsk. You have made the cat angry. ''You do NOT WANT to make the cat angry!''"
* Make no mistake. If you make Io (from the film ''Escape From Planet Earth'') angry, she'll flex her muscles like ''WesternAnimation/TheIncredibleHulk'', and then beat you up like a ''{{WWE}}'' superstar.
* ''Film/StarTrekIntoDarkness'': Harrison, of course, but Sulu also gives such a dire threat in a mission that Bones is unnerved by it.
-->'''Bones:''' Mr. Sulu, remind me never to piss you off.
* From ''Film/{{Serenity}}'':
-->'''The Operative''': Do you know what your sin is, Mal?
-->'''Malcolm Reynolds''': Ah hell, I'm a fan of all seven. But right now? I'm gonna have to go with ''wrath''.
* Don't pull a gun on Mongo from ''Film/BlazingSaddles'', you'll just make him mad.

[[folder: Literature ]]
* In ''[[{{Nightside}} A Hard Day's Knight]]'', John and Suzie use their own variant to intimidate an uncooperative laundromat employee:
---> '''Shotgun Suzie:''' You really want me to get cranky?
---> '''John Taylor:''' You wouldn't like her when she's cranky.
* In ''The Fairy's Mistake'' from ''Literature/ThePrincessTales'', Ethelinda substitutes Myrtle (who has snakes and insects come out of her mouth) for Rosella (who produces jewels). Myrtle-as-Rosella tells the GoldDigger prince that the snakes and insects come out of her mouth when she's angry, which gets him to start treating Rosella better.
* In ''Literature/LegacyOfTheForce'', Luke gives Jacen a quote almost identical.
* Literature/TheDresdenFiles
** Harry Dresden. Most of the time, as [[BadassNormal Karrin]] [[WillTheyOrWontThey Murphy]] notes, he's basically an oversized nerd who hunches slightly, speaks softly and never meets anyone's gaze, as if apologising for his size (and, in the latter case, looking to avoid [[WindowsOfTheSoul a Soulgaze]]), who cracks terrible jokes and does odd things. Then, someone makes the mistake of harming an innocent, someone under his protection, or, worst of all, someone he loves. After that, he opens his body up to his full height (nearly seven feet, and he isn't exactly stick thin either...) and thunders spells in a voice that can be heard 'from the other end of a football field' as he turns the fundamental powers of the universe into his personal plaything and unleashes them on whoever's pissed him off. It's a sight that is described as intimidating on an evolutionary scale, and usually results in a trail of destruction featuring any number of dead monsters, some [[PhysicalGod godlike in their powers]] and usually at least [[DestructiveSaviour one burning building.]] And if you've taken [[spoiler: his daughter]], he will find you and he will [[spoiler: commit genocide]]. You can pray to God, but he won't help you - [[CelestialParagonsAndArchangels his]] [[ChurchMilitant agents]] are more than likely to be backing Dresden up.
** Michael Carpenter is noted as an extremely nice and kind man who has time for everyone, even trusting his best friend with his family when he thought that said best friend [[spoiler: was partially possessed by a FallenAngel]]. He is also only a couple of inches shorter than Dresden, putting him at around two metres tall, he's got muscles to spare and if you offer him violence, or worse, threaten his family, he can and will kick the crap out of you. In fact [[spoiler:he nearly beat a man to death for putting a bomb on his daughter, and the bomber claiming it was in God's Will. Only Harry calling Michael out and saying if the man needs to die, let Harry do it, does Michael relent]].
** Ebenezer [=McCoy=] is one of the weakest members of the Senior Council. That said, the man is Harry's second mentor and Archmage-tier power. He is such a dangerous combat wizard, a professional assassin Harry hires to help with a job gets one look at Eb, who was there to help Harry too, and tries to run. Eb gets his gun and takes aim. It is revealed [=McCoy's=] reputation is well-deserved because [[spoiler:he is the personal assassin of the Senior Council, with full authority to break the laws of magic should adhering to them make the consequences even worse for the world]]. Against a vampire noble who tries to kill Harry in a duel by cheating, [=McCoy=] [[spoiler:drops an old Soviet satellite onto the vampire's house, killing him and everyone in the impact zone]].


[[folder: Live Action TV ]]
* The [[TropeNamers Trope Namer]] is ''Series/TheIncredibleHulk'' TV series, and its classic implied threat, delivered with a wonderfully understated and grim bemusement. And it's actually said ''before'' he becomes the Hulk.
-->'''Banner:''' Mr. [=McGee=], don't make me angry. You wouldn't ''like me'' when I'm angry.
* In ''{{Series/Smallville}}'', you really, ''really'' don't want to make [[spoiler:Davis Bloome]] angry. If you actually [[BerserkButton hurt Chloe]] in front of him, HaveANiceDeath.
** Pissing off Clark is generally a bad idea as well. He won't kill you, but he can and will make you wish that he had.
* It's been said in later episodes of ''Series/{{Torchwood}}'' that it's best not to piss Jack off. Take into mind this line from the ''Children of Earth'' miniseries (spoken by his daughter to the government spooks who just arrested her and her son):
-->'''Alice''': I can only assume you're using us as hostages against my father - but if you've done anything to anger him, then God help you.
* ''Series/DoctorWho''--
** You ''really'' don't want to piss off the Doctor. That seemingly harmless oddball can tear the heavens apart and reshape reality if he really wants to. There's a ''reason'' the Daleks, a race of {{Omnicidal Maniac}}s capable of wiping out all life in the universe, hate and fear him so much. They have no emotions, and they invented a number of names to call him by; the Destroyer of Worlds, The Oncoming Storm and the Predator.
** Ditto River Song. Sarcastic, teasing, likes to banter. And - ''can make a '''Dalek''' beg for mercy''. Just... don't make her go there.
** Similarly, in the prequel to "A Good Man Goes to War":
--> "...I even hear rumours about whose child you've taken. Are you ''mad''? [Pause] You know the stories about the Doctor? The things that man has done? ''God help us if you've made him angry!''"
-->(''from the actual episode'')
-->"If that man has started calling in his debts, then God help you... and God help his debtors."
** Surprisingly enough, Rory Williams. Kidnap one of his loved ones? Prepare to have [[OlderThanHeLooks the]] [[Really700YearsOld Last]] [[NamesToRunAwayFromReallyFast Centurion]] blow up your star-fleet.
* It is also best to not piss Jack from ''Series/TwentyFour'' off.
* Let's just say that the last time someone crossed [[Series/{{Lost}} Ben]] [[AffablyEvil Linus]] it didn't [[NoHoldsBarredBeatDown end]] [[BerserkButton well...]]
* Also, [[NotSoStoic pissing off]] Spock from ''Series/StarTrekTheOriginalSeries'' would be more than illogical. It's very hard to do, but once you manage it, ThisIsGonnaSuck doesn't cover your fate.
** On a related note, Data (without the emotional chip) is literally impossible to piss off. However, if you threaten him with harming his friends, you'll face a superintelligent, super-strong, nigh-indestructible android who has decided that ''removing you from existence is the completely logical solution under the current circumstances.''
** Sisko spends most of his time, at least in the early seasons, coming across as surprisingly mellow...because he keeps his temper on a very short leash, and when it comes out to play things get broken. The most ''constructive'' thing he did when furious was to design a ship solely for the purpose of killing things.
** Most of the time Q is a jovial TricksterGod who, while he messes with the crew of the ''Enterprise'', never really means to cause permanent harm. However, the one time Captain Picard mocked Q's offer of help in dealing with the unknown dangers of the galaxy and displayed unmitigated arrogance about the Federation's readiness, Q proceeded to throw the ''Enterprise'' seven thousand light years away from home and into the path of [[TheDreaded the Borg.]] For the remainder of the episode Q reminds the crew and the audience that he is essentially an old god who values the lives of the ''Enterprise'' crew only at his leisure.
* Inverted rather amusingly in ''Series/{{Angel}}'' when a woman offers to "[[UnusualEuphemism make him happy]]". Angel responds that "You won't like me when I'm happy", as the last time he made love he turned into the evil Angelus -- he's under a curse that will make him lose his soul if he experiences a moment of perfect happiness.
** Another woman finds her warlock father intends to offer her as a VirginSacrifice. When he uses this trope, she snaps back in SarcasmMode, "No, because then you might do something ''bad!"''


[[folder: Music ]]
* "The Power" by Snap:
-->Stay off my back / Or I will attack / And you don't want that

* In ''Pinball/MonsterBash'', one of the Wolfman's quotes is "You wouldn't like me when I change--!"

[[folder: Video Games ]]
* Doc Louis's ''PunchOut'' plays this completely straight. Midway through the fight, Louis pulls out a chocolate bar that he'll eat and restore all his health with if not interrupted. However, punching the bar out of his hand is the ultimate way to push his BerserkButton. He immediately flips out with the phrase - "NOOOOOO! NOW You've done it! You won't like Doc when he's angry!", proceeds to rip off his jacket, and his attack speed doubles. [[TheComputerIsACheatingBastard Right after pulling out another chocolate bar and healing himself out of your attack range.]]
* Zappa from ''VideoGame/GuiltyGear''. Although he's more of a "You Wouldn't Like Me When [[DemonicPossession My Ghosts]] Are Angry", his profile in the manual mentions this trope by name.
--> "Don't make him angry! [[ShoutOut You won't like him when he's angry!]]"
* In the "Grim Tales" quest in ''{{Runescape}}'', Glod the Giant shouts "[[HulkSpeak You wouldn't like Glod when Glod angry!]]"
* In ''VideoGame/DragonAgeOrigins'', [[OldSoldier Sten]] says the line almost word for word.
-->'''Sten''': In fear, I kill people. Pray that you don't see me in anger.
** Anders gets... blue... when he's upset in ''VideoGame/DragonAgeII'', thanks to Justice / Vengeance.
* Asura from ''VideoGame/AsurasWrath'' is practically the Japanese answer to the Hulk. Making him angry is not only inadvisable, but practically ''suicide''.
* Goliaths from ''VideoGame/{{Borderlands 2}}''. Shoot off their helmet, and they fly into a psychopathic fury that sees them attack the players and any enemies around indiscriminately. Two of the lines they can spit out before going berserk warn the player of the mistake they made by shooting off the Goliath's helmet.
--> '''Goliath''': ''Big mistake...Really big GOD DAMN MISTAKE!''
--> '''Goliath''': ''You shouldn't...you REALLY SHOULDN'T HAVE GOD DAMN DONE THAT!"
* In ''VideoGame/SandsOfDestruction'', Rhi'a's SuperMovePortraitAttack PreAssKickingOneLiner is arguably a variation of this trope, as she's normally quite mellow:
-->'''Rhi'a:''' Time to get a little mean.

[[folder: Web Original ]]
* In one ''[[Roleplay/GlobalGuardiansPBEMUniverse Butlerverse]]'' story, this line was quoted verbatim to [[SuperRobot Omega]] by [[FlyingBrick Stone]], after the villainous machine threatened an eight year old girl whose only "crime" was being a telepath. [[FriendToAllChildren One just doesn't threaten children in Stone's presence and expect to walk away unhurt]].
* Hulky of ''WebAnimation/KlayWorld'' says this word-for-word before [[InvokedTrope somebody takes him up on the challenge]]. Averted in that he actually gets smaller, weaker, and perhaps stupider when he gets mad. [[spoiler:Played straight later on when he gets really mad and turns huge and smashes everything]].
* Parodied in the WhateleyUniverse story "Tales of the [=MCO=]" when a commercial break comes. It's the Merchant-Ivory production of "Hulk 1809":
--> My lord, please do not make me angry. Thou wouldst not like me when I am most angered.
* The line is used in Lanipator's Main/YuYuHakushoAbridged movie, by Yukina, of all people. [[spoiler: It's promptly subverted when the villains ignore her and smash her into a wall.]]
* WebVideo/TheNostalgiaCritic might still be pathetic when he's having his little boy rages, but he has a tendency to explode buildings accidentally when he's like that.


[[folder: Western Animation ]]

* The Avatar State in ''WesternAnimation/AvatarTheLastAirbender'', as seen in the page pic.
** Some context: the Avatar is a individual who is reincarnated once per generation that alone has the ability to control fire, earth, water, and air (normal benders only controls the element of their birth). When the Avatar state kicks in, they temporarily gain the combined knowledge ''and power'' of all the previous Avatars, of which there has been untold generations of. Until the Avatar learns how to control it, it will kick in when he/she is either in danger of dying or highly distressed. At which point, their tactics and moral considerations consist of: Destroy threat. With extreme prejudice.
* Raven from ''WesternAnimation/TeenTitans'', as a result of being [[HalfHumanHybrid half-demon]]. The result of ticking her off is a demonic form that is less powerful than the Avatar State above, but probably worse to have as an enemy, as Raven can get downright ''sadistic'' when she's like this. (Poor [[HarmlessVillain Dr. Light]] never did get over what she did to him...)
--> '''Dr. Light:''' Don't! Stop! You win! I surrender!! AHHHHHHH!!
--> '''[[VoiceOfTheLegion Demon Raven]]:''' What's the matter? Afraid of the dark?
** Then, a season or two later:
---> '''Dr. Light:''' (with a new, more powerful suit) Haha! You can never defeat me!
---> '''Raven:''' [[CombatTentacles (best impersonation of her demonic half)]] Remember me?
---> '''Dr. Light:''' I'd like to go to jail now, please.
** Starfire is not exempt from this, either. When she first touched down on Earth, she was a raging berserker who nearly destroyed the city, and this was while she had her incredibly heavy restraints ''on''.
* In an episode of ''WesternAnimation/DextersLaboratory'', Dexter alters his tastebuds so he only like fruits and vegetables, but a side-effect is that he [[HulkOut Hulks out]] when he gets too hungry. He is denied food by someone later on, and uses a variation of the phrase, replacing "angry" with "hungry".
** [[HilariousInHindsight That same line happened]] (In Portuguese) in ''TheIncredibleHulk''.
* {{Droopy}} is always the calm and rational one - half of the time, he just looks flat out ''bored''. However, do something that angers him, he'll calmly walk up to you, ''grab you'' down to his level and tell you [[TranquilFury "You know what?]] [[ThatMakesMeFeelAngry That makes me mad."]] Cue asskicking.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** [[BadassPrincess Princess Luna]] Being a PhysicalGod and the representation of TheSacredDarkness. Do not piss off that mare.
** Woe to the pony who manages to piss off [[ShrinkingViolet Fluttershy]]. She can go from the nicest pony in Equestria to the most terrifying if you hurt her friends, and managed to out-stare a cockatrice ''[[TakenForGranite as it was turning her to stone]]'' while protecting some fillies.
** Rarity, surprisingly. The refined unicorn fashionista who once ''summoned a couch to faint on'' because she was ''not'' going to land on the ''dirty ground'' when she fell may overreact to things hilariously, but when actual danger shows up, she [[LetsGetDangerous gets dangerous]]. [[IKnowKungFu She knows kung fu]] and [[ActionFashionista isn't afraid to use it]] - she is actually ''more'' likely to resort to hooficuffs than Applejack, the rough-and-tumble farm pony and physically strongest member of the team.
* Timber Wolf from the ''WesternAnimation/LegionOfSuperheroes'', the reason why he's [[TheStoic the stoic]] of the team is if you piss him off [[HulkOut you'll have an 8 to 10' werewolf monster to deal with.]]
* Said word for word by Peter in an early episode of ''WesternAnimation/FamilyGuy'', when he was "[[BlatantLies explaining]]" why he canceled a reservation at the local SuckECheeses. In his flashback, he ends up being restrained by a [[ThoseWackyNazis Hilter-worshipping]] manager dressed as [[{{Satan}} the devil]], before delivering the line and, naturally, HulkingOut. At that point Lois calls him out, and he's amusingly still in his Hulk pose as the "flashback" ends.
* Lucas Amato from ''WesternAnimation/CyberSix'' gets this reaction from his students: an entire trio of delinquents who are about to rough up Julian turn tail and run as soon as he shows up. The only thing keeping him from falling squarely into TheDreaded territory is that he's a really nice guy and actually well liked by his students.
* Inverted in ''WesternAnimation/AvengersAssemble'' when Thor states that he actually likes Hulk when he's angry
* In the ''WesternAnimation/AladdinTheSeries'' episode "The Way We War", Genie goes berserk when he thinks Aladdin's life has been claimed as a result of the fighting, swelling up into a threatening stature and screaming how the fighters on both sides had better stop right now, as they ''do not'' want to see what happens if you push a genie too far.
