History Main / HulkingOut

* In the climax of ''WesternAnimation/HotelTransylvania2,'' [[spoiler:Dennis finally grows his fangs and [[TookALevelInBadass becomes unstoppable]] after Vlad and his minions attack Winnie.]]

See also OneWingedAngel, LimitBreak, SuperMode, TurnsRed, GrowingMusclesSequence and LivingMoodRing. Compare and contrast WorkingOutTheirEmotions, where rage (or another similarly negative emotion) drives someone to get stronger the old fashion way.

** The [[WesternAnimation/TheLEGOMovie2TheSecondPart sequel]] takes it UpToEleven with Ultrakatty, a huge, red cat that Unikitty can become via getting really mad.

* In ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'' episode "The N-Men" after crossing through the Van Patten Radiation Belt, the main characters all wind up getting superpowers based on what exactly they were doing when they crossed through the belt. Jimmy was under a state of incredible frustration as they crossed through the belt which combined with the stress of handling the other characters; the constant mockery that Jimmy goes under in this episode, only triggers the Hulk Out.

* Tony Tony Chopper from ''Anime/OnePiece'' turns into a giant muscular, shaggy furred, monstrous version of himself dubbed "Monster Point" when he eats three Rumble Balls under less than six hours. In this form, he goes berserk with rage and attacks anyone nearby, so he only uses this as a last resort, and after the transformation is reversed he is left with a lot of strain on his body. By the time of the Fishman Island Arc, he has learned to control himself while in this state (and is the only form he needs a Rumble Ball to turn into), but he can only hold this transformation for three minutes.

* Parodied with a RunningGag in ''Manga/TokyoGhoul[=:Re=]''. The so-called "[[FanNickname Hulk Urie]]" is a fictional version of Urie, drawn by [[{{Otaku}} Saiko]] to mock his strict workout regimen. She even draws a comic where the normal Urie transforms into Hulk Urie to rescue the team. He is... less than amused by her creative presents.

* Prozac of ''Webcomic/BearNuts'' goes HULK SMASH after a prolonged time off his meds.

** Earlier in ''Anime/DigimonAdventure'' Tai became obsessed with getting Agumon to digivolve to the ultimate level. The end result was [=SkullGreymon.=]

* Negi's Magia Erebea form in ''MangaNegimaMagisterNegiMagi''

* ComicBook/SheHulk (AKA Jennifer Walters), at first. In fact, she had it worse than her cousin, [[ComicBook/TheHulk Bruce]]. While Bruce could, on occasion, notice his emotions were running too high and get them under control before transforming. Jennifer, by contrast, couldn't calm down or stop the transformation. Once her emotions ran too high, it was like a ticking time-bomb. All she could do is try to get to an isolated spot to transform. Fortunately for her, she later gained control of her transformations entirely.

* ''Franchise/{{Digimon}}'':
** {{Mon}} example from ''Anime/DigimonTamers'': when [[spoiler:Beelzemon kills Leomon]], Takato becomes so furious it causes Guilmon to evolve into the highly unstable and uncontrollable Megidramon.
** Earlier in ''Anime/DigimonAdventure'' Tai became obsessed with getting Agumon to digivolve to the ultimate level. The end result was [=SkullGreymon.=]

* Manga/{{Naruto}}'s SuperpoweredEvilSide tends to come out when he's angry.
* This happens to [[TheBrute Yammy Llargo]] in ''Manga/{{Bleach}}'', only he Hulks Out when he was already the size of a football stadium.
* In ''Manga/DesertPunk'', desert gang leader Makoto has what's described as a case of [[LampshadeHanging "Hulk Syndrome."]] Say his mother has a fat belly button (or just call her a "dirty whole" in the English dub), and he grows huge muscles, goes berserk, and destroys anyone who crosses him. And that's after taking a long string of taunts without batting an eye.
* In chapter 305 of ''Manga/HunterXHunter'', [[spoiler:KidHero Gon]] Hulks Out when Pitou admits that [[spoiler:Kite is already dead and beyond any help]]. [[spoiler:He turns into a muscular long-haired adult whose raw power rivals that of the ''Chimera Ant King'']]. Overlaps with DangerousForbiddenTechnique since [[spoiler:Gon accomplished this by forcefully aging himself; reducing his lifespan and (maybe) sacrificing the ability to use nen ever again]].
* A rare female example of hulking out occurs in ''Anime/AngelCop,'' where the psychic Lucifer enlarges her muscles, going from silky-smooth to rippling in an instant.
* Never get Stella from ''Manga/ArakawaUnderTheBridge'' in her bad mood, especially talking ill about [[WholesomeCrossdresser Sister]], you will regret it.
* Kenshiro from ''Manga/FistOfTheNorthStar'' is a minor version- [[https://www.youtube.com/watch?v=3ebC8EVe1JQ pretty much every fight scene starts with him rip his jacket to shreds by tripling the size of his muscles]] (they're back by the next scene). Several mooks use their special abilities to increase in size, [[MusclesAreMeaningless not that it helps any.]]

* ''Manga/FairyTail'': [[http://static1.wikia.nocookie.net/__cb20120411143502/fairytail/images/0/0c/Power_Perfume.gif such]] is the effect of the Power Perfume in Ichiya's arsenal. MagicPants are included, of course.
* In ''Manga/GreenWorldz'', the female human hybrid does this by having wood branches surround her body when she starts getting a little serious.

* This is basically how the Unicorn of ''Anime/MobileSuitGundamUnicorn'' enters its Gundam mode: by reacting to an extreme state of emotion in its pilot and entering "Destroy Mode." This results in its joints opening up, revealing a glowing red psycoframe, increasing its power massively, and splitting its "horn" into the characteristic Gundam V-fin. Learning how to control it (instead of just blasting every enemy to smithereens) is a big problem for Banagher. (Riddhe, by contrast, ''embraces'' the idea of going uncontrollably berserk when he hops into its Banshee counterpart.)
* In ''Manga/RikiOh'' and its anime adaptation, [[BigBad The Warden]] uses his mastery of [[SupernaturalMartialArts Naike Kenpou]] (The same martial art that gives Riki his abilities) to disguise his true form: A hulking oni-like beast. He hulks out when he releases that control.

* Zigzagged with [[AxeCrazy Jin'ei Udo]] from ''Manga/RurouniKenshin'': his ace in the sleeve allows him to go from a scrawny gaunt man to a behemoth ripping with bulging muscles (averting ClothingDamage since he's wearing a full-body suit and just unrobes the upper half of his kimono in advance), but averts the rage part: not only he transforms by hypnotizing himself, but he also becomes calmer and less unhinged when the transformation is active.
* Played for laughs in ''Manga/HowHeavyAreTheDumbbellsYouLift'' with Machio, who routinely shreds his clothes when he flexes, going from a reasonably fit young man to a hulking mountain of muscle in an instant. It's gotten him into trouble when he does it in public.
* ''Manga/MyHeroAcademia'': Re-Destro's Quirk, "Stress", is effectively this. His Quirk bottles up all of the rage and stress he feels into his body which he then uses to bulk himself up to gigantic proportions in order to release his stress on whoever has incurred his wrath.
* Tony Tony Chopper from ''Anime/OnePiece'' turns into a giant muscular, shaggy furred, monstrous version of himself dubbed "Monster Point" when he eats three Rumble Balls under less than six hours. In this form, he goes berserk with rage and attacks anyone nearby, so he only uses this as a last resort, and after the transformation is reversed he is left with a lot of strain on his body. By the time of the Fishman Island Arc, he has learned to control himself while in this state (and is the only form he needs a Rumble Ball to turn into), but he can only hold this transformation for three minutes.

* ''ComicBook/SonicTheComic'' has Sonic transform into Super Sonic when angered or stressed. While Super Sonic was the same size as Sonic, he fits the rest of the description. However, unlike most examples of this trope, Super Sonic could not be controlled and was dangerous for virtually everyone- even Sonic's friends weren't safe.

* Walter/Wallop from ''ComicBook/ClanDestine'', though he doesn't so much lose intelligence as control. The longer he stays transformed, the bigger, stronger and more out of control he gets.

* Subverted and {{lampshade|Hanging}}d in ''ComicBook/{{Invincible}}'' when Mark tries to hulk-out over [[spoiler:Atom Eve's death]] and will beat Conquest. Conquest rushes Mark and tells him "child, please. Being enraged at me does not make you stronger. That is not how this works." [[spoiler:Then again, Mark ''does'' nearly kill Conquest afterward, so...]]
* It's not easy to make a Hulk desperate. Push [[ComicBook/BettyRoss Red She-Hulk]] far enough, though - say by overwhelming her with an army of {{supersoldier}}s - and she Hulks Out again, turning into a rampaging creature running on pure survival instinct.
* In recent years, Franchise/{{Batman}} villain ComicBook/TheScarecrow has reacted to great rage or pain by involuntarily transforming into the hulking monster [[http://img1.wikia.nocookie.net/__cb20110110022213/marvel_dc/images/c/c8/Scarebeast_003.jpg Scarebeast]] on some occasions. He does not seem to retain any memory of these interludes.
* In a story about the Franchise/JusticeLeagueOfAmerica told by J'onn J'onnz, the ComicBook/MartianManhunter himself went through a Hulking Out moment when the ComicBook/BlueBeetle and ComicBook/BoosterGold played a prank on him due to his addiction to [[TrademarkFavoriteFood Chocos cookies]], by hiding a stash of his favorite cookie away from him in a warehouse and having all the nearby stores that sell Chocos be completely empty of their stock.
* Roberta Mendez, first introduced as ComicBook/CaptainAmerica 2099 in Marvel's ''ComicBook/SecretWars2015'' event and later becoming a canon part of ''ComicBook/SpiderMan2099'', goes from a perfectly normal executive assistant to being built like a female weightlifter when the super-soldier serum in her system gets activated.
* Parodied in ''ComicBook/GreatLiesToTellSmallKids'', which claims Banner only half-hulks when he's irritated (such as by being asked to do the dishes).
* ''ComicBook/TheLeagueOfExtraordinaryGentlemen'': Dr. Jekyll's body produces the serum that turns him into the much larger Mr. Hyde whenever he's stressed. He spends nearly the entire Martian invasion arc in Hyde form.
* ''ComicBook/{{Slaine}}'', being based on Myth/CelticMythology, borrows Cúchulainn's Warp-Spasm for the titual hero.
* Occurs in ''ComicBook/TheBoys'' with [[spoiler: M.M.'s younger brother]]. His powers manifested suddenly one day, with one small catch; he was mentally disabled and wore a helmet [[RequiredSecondaryPowers which he couldn't break out of, crushing his skull and killing him.]]

** Another example (minus the physical growth part), is near the end of the first book and in the sequel, is [[spoiler: Harry]] turning into the Phoenix - the first time after being killed, and promptly resurrected and possessed by the Phoenix Force, which goes on a RoaringRampageOfRevenge, the second after figuring out how to use the fragment of the Phoenix within, and finally snapping after a ''brutal'' TraumaCongaLine. Since this results in [[TheDreaded the Dark Phoenix,]] everyone is very eager for this never to happen ever again.

* In ''WesternAnimation/HeavyMetal'', Hanover Fiste (with the help of the [[ArtifactOfDoom Loc-Nar]]) hulks out to disrupt Capt. Sternn's trial and allow him to escape.
* In the climax of ''WesternAnimation/HotelTransylvania2,'' [[spoiler:Dennis finally grows his fangs and [[TookALevelInBadass becomes unstoppable]] after Vlad and his minions attack Winnie.]]

* In ''Film/BigTroubleInLittleChina'', Thunder seems to be doing this when he sees that his elemental brothers; Lightning and Rain; are dead. He starts expanding....then he keeps expanding....and then he blows up.
* ''Film/RikiOhTheStoryOfRicky'': [[BigBad The Warden]] plays this straight, basically turning into an {{oni}} (rather than the inverted version of his anime and manga counterparts, who transforms into the smaller normal human).

* In ''Literature/{{Twilight}}: New Moon'', Jacob and the other werewolves sometimes change into wolf form because of anger. The pack leader Sam's fiancee has disfiguring scars because Sam "lost control for a split-second."

* ''Literature/EgilsSaga'': Watching the burial of his favorite son Bodvar, Egil "swell[s] up so much" that his tunic and his leggings tear apart. When he comes home, "no one dare[s] to speak to him", suggesting that they are afraid of him 'going berserk'. Egil instead locks himself in his sleeping room and does not come out for three days.

* A prizefighter in the ''Series/LostGirl'' episode "Raging Fae" keeps beating stronger foes because a Fae is secretly dosing him with a Hulk Out-inducing substance.
* PlayedForLaughs in ''Series/TheYoungOnes''. After receiving a merciless barrage of abuse from all three of his housemates, Neil does this in the ''Summer Holiday'' episode. [[spoiler:Turns out it was actually an IndulgentFantasySegue, though it's a mystery what happened to his clothes...]]

* Yet another werewolf example. In ''Series/BigWolfOnCampus'', Tommy would not only transform during a full moon but also during times of extreme emotional stress... or arousal.
* [[https://www.youtube.com/watch?v=bRsVlOpz3Yc One prank]] in ''Series/JustForLaughsGags'' had a small boy wearing purple pants have his hat stolen, walk into a nearby portapotty - where he's lifted out through a door in the back by a large man painted green and wearing similar clothes as the boy, then gets in - and then rattles and breaks it open, yells and chases the kids.

* Going "full-on zombie mode" in ''Series/{{iZombie}}'' is usually triggered either by immediate danger or hunger for brains. The zombie's eyes go [[BlackEyesOfEvil black]], and he or she attacks with inhuman strength and ferocity. Bonus points for one of the zombies calling the state "raging out" (who has learned to enter the mode on demand).
* ''Series/TheAmazingExtraordinaryFriends'': Dr. Dominique Brioche suffers a nuclear genetic accident and transforms into the 50 ft. Atomic Bombshell whenever she gets angry.
* ''Series/AgentsOfSHIELD'':
** Calvin Zabo ([[spoiler:Skye's father]]) has been using a homemade PsychoSerum on himself for decades. Therefore, even when he's not actively using it, he can achieve great feats of strength when angered. His catchphrase is "Let's not lose our heads." His actual serum is even more powerful, resulting in a small but striking physical transformation, and is activated by rage and [[spoiler:a shot of adrenaline]].
** Subverted with Robbie Reyes, AKA Ghost Rider. When he gets angry at widespread looting during a blackout, Daisy warns him to keep calm so he doesn't "go all [[FlamingSkulls carrot top again]]." Robbie laughs, as the Rider has nothing to do with his emotional state. It only comes out when [[DetectEvil there's evil around]], and even then Robbie can usually keep it contained until things get desperate.
* Played for laughs in the ''Series/{{Community}}'' episode "Contemporary Impressionists". As the gang is working a bar mitzvah as celebrity impressionists, Jeff gets so angry at not winning a "Most Handsome Young Man" contest that the he bursts the seams of his suit and goes on a rampage of destruction. The guest of honor thanks his dad for getting him the Incredible Hulk for his party.

** And [[TabletopGame/WerewolfTheApocalypse their]] [[TabletopGame/VampireTheMasquerade predecessors]] in the ''TabletopGame/OldWorldOfDarkness'' can also frenzy in many of the same situations. One possible flaw in ''Werewolf: the Apocalypse'' can [[InvertedTrope invert it]] - it designates one of the werewolf's other four forms as the form transformed into. The most severe version of it turns the raging werewolf into their human form - not so bad (comparatively) if you're losing your temper at the bar, but if you're surrounded by fomori and Black Spiral Dancers and need to fight your way out? Good luck.
* In the Arthaus edition of ''TabletopGame/{{Ravenloft}}'', darklord Alfred Timothy inverts this trope: he's a malicious and willing werewolf, but his darklord curse forces him to revert to his ''human'' form if he allows anger, bloodlust, passion, or other strong emotion to overcome him while in his wolfman form.

* Bowser only reaches [[MakeMyMonsterGrow his highest level of power]] in ''VideoGame/MarioAndLuigiBowsersInsideStory'' after being (otherwise fatally) crushed, with a little help from the Mario Bros.
* In ''VideoGame/VampireTheMasqueradeBloodlines'', there are several ways of unleashing The Beast, which Smiling Jack describes as a beast wearing you as a suit, in which you go into an uncontrollable frenzy.

* In ''VideoGame/{{Amagon}}'', the titular player character transforms into the Hulk-like Megagon for SuperMode.
* One ''VideoGame/WorldOfWarcraft'' expansion introduces worgen, humans afflicted by a werewolf curse, as a playable race. While they eventually learn to shift between human and worgen form at will, entering combat immediately shifts them into worgen form. Some even say "YouWouldntLikeMeWhenImAngry" if you [[StopPokingMe click on them enough.]]
* Anders in ''VideoGame/DragonAgeII'', whenever he is overtaken by the Spirit of Justice inhabiting him.
--> '''Justice''': '''[[AC: You will never take another Mage as you took him!]]'''
* Despite rage being a main theme, Asura from ''VideoGame/AsurasWrath'' primarily averts this. He does, however, grow bigger arms that pack at least a thousand times more power in them in his [[SuperpoweredEvilSide Berserker form]], his [[ConservationOfNinjutsu Mantra form]] and his [[AttackOfThe50FootWhatever Destructor]] [[HumongousMecha form]] (Which also has a human-sized form, that basically is Asura mantra form, but with four extra arms and a rainbow aura instead of Asura's plain red Aura).
* In ''VideoGame/TransformersFallOfCybertron'', Grimlock's alternate mode is somewhere between this and SuperMode. In-game, the transformation isn't involuntary and can't be done at will due to being experimented upon by Shockwave, but it does require Big Grim getting incredibly pissed to gain access to it and he does grow in size upon transforming.
* One of Krieg's endgame abilities in ''VideoGame/Borderlands2'', "Release The Beast", has him mutate into a Badass Psycho when he activates Buzzaxe Rampage at 1/3 of his health. The mutation involves his left arm shriveling into a worthless stump while his torso and right arm grow to ridiculous size, giving him a massive boost in damage resistance as well as melee damage.
* While not shown, Leo Hartwig's in ''VideoGame/BioShock2'' transformation into a Brute Splicer involves this. It is heard in his Audio Diary "Field Trial #1".
* ''VideoGame/{{Overwatch}}'' has Winston, whose [[LimitBreak Ultimate]] consists of him temporarily regressing into his primal instincts and becoming an AxCrazy muscular brute who trades off his [[ShockAndAwe Tesla Cannon]] for powerful punches, faster Jump Pack cooldown, and doubled HP.

* ''Webcomic/{{MAG ISA}}'' -- [[http://mag-isa.thecomicseries.com/comics/pl/119791 Kyle]] turns into this chunk of muscle after injecting himself with green roids.
* Fug from ''[[http://www.pewfell.com/ Pewfell]]'' is normally a GentleGiant... until he gets angry, then he turns into something resembling an EldritchAbomination with arms.
* Shrinking Violent of ''Webcomic/EverydayHeroes'' has her transformation triggered with a blow to the nose. She can be snapped out of it via massive amounts of sugar. Unfortunately [[BlessedWithSuck she's also a Type 1 Diabetic]], which means a couple of days in the hospital after every Hulk Out, at best. Also, she gets ''smaller'' when she transforms. Her muscles contract and get denser, so [[http://eheroes.smackjeeves.com/comics/1895761/violets-in-the-workplace/ even her strongest teammate can't hold her down.]]
* Sarah of ''Webcomic/PeterIsTheWolf''. As a new Thrall ([[IHateYouVampireDad a were who's created, rather than born]]), she tends to transform whenever she gets too excited. Unlike every other were in the comic, she transforms into a wolf form three times her normal size and can only really be calmed down by [[IntimateHealing sexual gratification]].

* Sweater Puppy and The Incredible Cunt from ''Webcomic/TheMagnificentMilkmaid''. Both turn into giant, large breasted [[AnythingThatMoves nymphomaniacs]] (in SP's case, a nymphomaniac werewolf) upon their triggers (Sweater Puppy from seeing or even thinking about the Moon, Incredible Cunt from being called "a cunt").

* The Incredible Lioness, a transformation of Rosechu from ''Webcomic/{{Sonichu}}''.
* In ''Webcomic/SisterClaire'', apparently masters of Nun-Fu can [[http://www.sisterclaire.com/comic/book-1-chapter-8-pg-192 do this at will.]]
* In ''Webcomic/{{Tripp}}'', [[spoiler:Coco does this after aliens put a chip in her head]].

* Demons from ''Webcomic/SlightlyDamned'' have this as a race ability, in extreme stress, anger, injury or if they know death is certain [[TakingYouWithMe willingly]], they transform into larger more monstrous versions of their normal selves[[labelnote:example]] [[spoiler:Buwaro]] goes from a bipedal human-sized teenager to a sabertoothed quadruped with a burning tail.[[/labelnote]] and get a massive boost to their physical and magical capabilities but lose all self-preservation and will [[AttackAttackAttack mindlessly slaughter]] any living thing they see (including friends and family) or [[SelfHarm mutilate themselves]] if there is nothing to kill. Their body is also pushed to its absolute limit and they eventually die of exhaustion although it is possible to save them by either rendering them unconscious (easier said than done given [[MadeOfIron how tough]] they are normally) or by using [[spoiler:an angel star pendant with the [[ProtectiveCharm holy protective spell]] removed]].

* In the ''WesternAnimation/WordGirl'' episode introducing Eileen (The Birthday Girl), the more she was selfish the bigger she grew and the greener she got; once she gave somebody something she returned to normal size and color.
* In ''WesternAnimation/TheVentureBrothers'' Doctor Venture once thought Hank to be blessed with "retard strength" but was mistaken.
* ''WesternAnimation/SouthPark'':
** Parodied in the episode "[[Recap/SouthParkS14E9ItsAJerseyThing It's a Jersey Thing]]", when Kyle's "Jersey side" comes out. Only the "transformation" is him putting on hair gel and jewelry, ripping off his sleeves and writing a nickname on his shirt.
** Played straight in the episode "A Scause For Applause" when [[spoiler:Jesus takes HGH at the end]]. [[http://southpark.cc.com/clips/7nwgwx/what-would-jesus-do The scene that follows that]] has to be seen to be believed.
* Laura Limpin from ''WesternAnimation/CodenameKidsNextDoor''. Every time something doesn't go her way, she transforms into a giant raspy-voiced wrestler called "The Big Badolescent" and [[CurbStompBattle beats up anyone who disagrees with her.]]
* On ''WesternAnimation/JimmyTwoShoes'', Heloise spends an entire episode in a SweetPollyOliver disguise named Herman. When Jimmy and Beezy find out, they find "Herman" and proceed to utterly prank him. Just as they are laughing at him, [[MistakenForAnImposter the real Heloise shows up]]. It seems Herman is her real cousin, and they made him mad...

* From ''WesternAnimation/TheSimpsons'': HOMER MAD!!! HOMER SMASH!!! GET REVENGE ON WORLD!!!
-->'''Stan Lee:''' He can't be the Hulk! I'm the Hulk! ''[rips shirt]'' Mrrrroaarrr! ''[breathes heavily]''
-->'''Comic Book Guy:''' Oh, please. You couldn't even change into Creator/BillBixby.
-->'''Stan Lee:'''Come on, damnit, change! Mmmmm! Aw, forget it. Mm-mmmm! [[NoodleIncident I really did it once]]!
-->'''Comic Book Guy:''' ''[walking Stan Lee in the store]'' Yes, yes. I just wish you had the power to leave my store.
-->'''Stan Lee:''' ''[off-screen]'' Mmmmmh!
-->'''Comic Book Guy:''' You almost had it there.
* Fuzzy Lumpkins in ''WesternAnimation/ThePowerpuffGirls'' episode "Fuzzy Logic". The mayor, of all people, momentarily becomes totally '''ripped''' and delivers a [[CrouchingMoronHiddenBadass major ass kicking]] in "Impeach Fuzz" after Fuzzy [[BerserkButton wears his hat.]]

* ''WesternAnimation/CaptainSimianAndTheSpaceMonkeys'':
** About halfway through the series, Gor-illa gets an upgrade from an UnstoppableRage to this at the hands of recurring antagonist Ajax, causing him to transform into the berserk KingKongCopy Gormungus whenever his rage builds high enough.
** In the same episode, one of Gor's initial opponents looks like an emaciated little bird-man alien about the size of Spydor. Gor expresses reluctance at fighting someone some small and harmless looking, whereupon Spydor angrily asserts that it's "dog-eat-dog" in this business. When Gor [[LiteralMinded protests that he doesn't want to eat a dog]], the alien grins a toothy grin... ''[[BodyHorror and then turns himself inside out]]'', transforming into a hulking monstrosity that vaguely resembles a skinned gorilla with spikes growing out of it.
---> '''Spydor''': [[OhCrap Well, this dog wants to eat you!]]
* In ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'' episode "The N-Men" after crossing through the Van Patten Radiation Belt, the main characters all wind up getting superpowers based on what exactly they were doing when they crossed through the belt. Jimmy was under a state of incredible frustration as they crossed through the belt which combined with the stress of handling the other characters; the constant mockery that Jimmy goes under in this episode, only triggers the Hulk Out.
* ''WesternAnimation/TheClevelandShow'': The episode "Once Upon a Tyne in New York" ends with Coach [=McFall=] and the others running from his old flame, who is now green and muscular.
-->'''[=McFall=]:''' I've made her angry! You wouldn't like her when she's angry!
* The animated ''[[Series/ElChavoDelOcho El Chavo]]'' series occasionally has Señor Barriga turning into a LawyerFriendlyCameo version of the Hulk in either the opening or closing sequences (or both).
* Spear the caveman from ''WesternAnimation/Primal2019'' undergoes this when he drinks a [[SuperSerum black liquid]] that had been used to make a gorilla-man bigger and stronger. Spear becomes a giant, monstrous version of himself who tears his opponents apart with ease.

* Naturally, the {{Trope Namer|s}} and [[TropeCodifier Codifier]] is ComicBook/IncredibleHulk. The writers of ''Series/TheIncredibleHulk1977'' Live-Action TV series officially called it "Hulking Out."

* In ''ComicBook/WildCATS'', the team's GeniusBruiser has the power to grow in size and strength at the cost of intelligence. If seriously provoked he sometimes forgets himself and grows past the point where he can tell friend from foe.

** Goku was subject to transforming into a giant ape-like creature with [[BreathWeapon laser breath]] when gazing at a full moon. In ''Anime/DragonBallZ'', Goku's son, Gohan had the same "issues". Cutting off their Saiyan tails reversed the transformation. Vegeta, having had the proper training, was in full control of his Oozaru form.

* Tony Tony Chopper from ''Anime/OnePiece'' when he eats three rumble balls it causes him to turn into a giant muscular, shaggy furred, monstrous version of himself dubbed “Monster Point” in this form he goes berserk with rage and attacks anyone nearby, he only uses this as a last resort and after the transformation is reversed it puts a lot of strain on his body, by the time of the “Fish Man Island Arc” he has learned to control himself while in this state.

[[quoteright:350:[[Comicbook/IncredibleHulk https://static.tvtropes.org/pmwiki/pub/images/1084894-440px_hulk_13_super.jpg]]]]

* Tony Tony Chopper from Anime/OnePiece when he eats three rumble balls it causes him to turn into a giant muscular, shaggy furred, monstrous version of himself dubbed “Monster Point” in this form he goes berserk with rage and attacks anyone nearby, he only uses this as a last resort and after the transformation is reversed it puts a lot of strain on his body, by the time of the “Fish Man Island Arc” he has learned to control himself while in this state.

** Gohan as a Super Saiyan 2 in the Cell Saga is this as his rage makes him one of the most sadistic characters in the anime besides from Broly and Kid Buu. Even Cell refers to him as a monster. Gohan is also very muscular for a 12-year-old.

* Spear the caveman from ''WesternAnimation/Primal2019'' undergoes this when he drinks a [[SuperSerum black liquid]] that had been used to make a gorilla-man bigger and stronger. Spear becomes a giant, monstrous version of himself who [[{{Gorn}} graphically]] tears his opponents apart with ease.

* ''Manga/MyHeroAcademia'':
** Re-Destro's Quirk, "Stress", is effectively this. His Quirk bottles up all of the rage and stress he feels into his body which he then uses to bulk himself up to gigantic proportions in order to release his stress on whoever has incurred his wrath.
** This is actually a secret ability of [[spoiler:[[{{Gonk}} Fat Gum]]. While at first his Quirk's sole function is to [[{{Kevlard}} use his giant fat body to act as a wall]], he can absorb any amount of force against him and apply it as a high-powered attack, at the cost of burning all of his protective fat at once due to the energy required to convert the force, resulting him turning very muscular.]]

* In ''Manga/MyHeroAcademia'', Re-Destro's Quirk, "Stress", is effectively this. His Quirk bottles up all of the rage and stress he feels into his body which he then uses to bulk himself up to gigantic proportions in order to release his stress on whoever has incurred his wrath.

* ''Manga/RosarioToVampire'': Though the exact transformation varies, monstrels' bodies change in battle. and a few of them become huge. Importance to the team tends to have something to do with it; weaker monstrels experience ShapeshifterWeapon, whereas the big boss instead goes OneWingedAngel.

* In ''Manga/{{Attack on Titan}}'', the [[HumanWeapon Shifters]] unleash their Titan form by using [[https://www.youtube.com/watch?v=GLff3_jPZIM bodily harm as a catalyst]] for their [[YouWouldntLikeMeWhenImAngry intense emotion/willpower]]. Each transformation involves lightning falling from the sky and bomb shockwave.

* Negi's Magia Erebea form in ''Manga/MahouSenseiNegima''

* Naturally, the {{Trope Namer|s}} and [[TropeCodifier Codifier]] is Comicbook/IncredibleHulk. The writers of ''Series/TheIncredibleHulk1977'' Live-Action TV series officially called it "Hulking Out."
* ''Comicbook/SonicTheComic'' has Sonic transform into Super Sonic when angered or stressed. While Super Sonic was the same size as Sonic, he fits the rest of the description. However, unlike most examples of this trope, Super Sonic could not be controlled and was dangerous for virtually everyone- even Sonic's friends weren't safe.

* In ''Comicbook/WildCATS'', the team's GeniusBruiser has the power to grow in size and strength at the cost of intelligence. If seriously provoked he sometimes forgets himself and grows past the point where he can tell friend from foe.
* Walter/Wallop from ''Comicbook/ClanDestine'', though he doesn't so much lose intelligence as control. The longer he stays transformed, the bigger, stronger and more out of control he gets.
* Marvel storylines ''ComicBook/WorldWarHulks'' and ''ComicBook/HulkedOutHeroes'' had several big-name heroes Hulking Out after being exposed to an enemy superweapon to make them go on a rampage. ComicBook/{{Deadpool}}, several members of the Comicbook/XMen, all of the ComicBook/FantasticFour except [[ComicBook/MisterFantastic Reed Richards]], [[Comicbook/TheMightyThor Thor]] (who seems to be weaker in this form), Franchise/SpiderMan, and even Comicbook/DoctorStrange were all Hulk-ified. Naturally, they all fell victim to TheWorfEffect -- and Hulk.
** Even Comicbook/SheHulk Hulked Out even more in ''Comicbook/AvengersDisassembled'': becoming larger, stronger and uglier as she went berserk over ComicBook/TheVision attempting to kill them. She's done that before... TWICE. Both instances occurred during her Sensational title. The first instance involved her in a pocket dimension, finding herself back to human form (despite being locked into her Hulk state at the time) and transforming into an enormous grey Incredible She-Hulk when night fell (incidentally, this was originally how Bruce Banner's change triggered as well), although the series of events that caused this to happen were [[StatusQuoIsGod subsequently undone]]. The second instance involved her ex-boyfriend bringing her back from the dead with gamma radiation, causing her to get bigger, uglier and a lot stronger.

* One ''Videogame/WorldOfWarcraft'' expansion introduces worgen, humans afflicted by a werewolf curse, as a playable race. While they eventually learn to shift between human and worgen form at will, entering combat immediately shifts them into worgen form.

* Anders in ''Videogame/DragonAgeII'', whenever he is overtaken by the Spirit of Justice inhabiting him.

* One of Krieg's endgame abilities in ''Videogame/{{Borderlands 2}}'', "Release The Beast", has him mutate into a Badass Psycho when he activates Buzzaxe Rampage at 1/3 of his health. The mutation involves his left arm shriveling into a worthless stump while his torso and right arm grow to ridiculous size, giving him a massive boost in damage resistance as well as melee damage.

* In addition to the various Hulks, several other characters in ''VideoGame/LEGOMarvelSuperHeroes'' share the same property, transforming from a minifig into a larger figure with super strength. Most notable are probably {{ComicBook/Venom}} and Creator/StanLee himself when unlocked as a playable figure, possibly in reference to ''The Simpsons'' episode mentioned below.

* Played for laughs in ''Manga/DanberuNanKiroMoteru'' with Machio, who routinely shreds his clothes when he flexes, going from a reasonably fit young man to a hulking mountain of muscle in an instant. It's gotten him into trouble when he does it in public.

* In the climax of ''WesternAnimaton/HotelTransylvania 2,'' [[spoiler:Dennis finally grows his fangs and [[TookALevelInBadass becomes unstoppable]] after Vlad and his minions attack Winnie.]]
