Ayano: Is he having some sort of allergic reaction?
Kazuma: I don't know but I'd be worried if my body did that, seems like you would go through a lot of pants that way.This trope is what happens at the intersection of You Wouldn't Like Me When I'm Angry, Shapeshifting (often of the involuntary kind) and Unstoppable Rage. Generally the trope goes like this:
— The reaction to seeing someone Hulk Out in Kaze no Stigma
- Character X is angered or in pain or some specific trigger is invoked.
- X reaches the breaking point and transforms into something at least twice his normal size. Skin color usually changes as well.
- Stuff gets broken until there's nothing else to break or X gets talked down from his rage.
- Cue change back to X's normal state — unless Magic Pants are involved. This might result in Monster Modesty.

Anime & Manga
- In Dragon Ball, Goku was subject to transforming into a giant ape-like creature with laser breath when gazing at a full moon. In Dragon Ball Z, 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.
- Going Super Saiyan is even closer to the trope; most Saiyans' first transformations come when they get really, really angry, and they really do get stronger the angrier they get. And when they combine anger with purpose... you're boned.
- Broly is probably the best example of this in the series.
- 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.
- Mon example from Digimon Tamers: when Beelzemon kills Leomon, Takato becomes so furious it causes Guilmon to evolve into the highly unstable and uncontrollable Megidramon.
- Earlier in Digimon Adventure Tai became obsessed with getting Agumon to digivolve to the ultimate level. The end result was SkullGreymon.
- Negi's Magia Erebea form in Mahou Sensei Negima!
- Naruto's Superpowered Evil Side tends to come out when he's angry.
- This happens to Yammy Llargo in Bleach, only he Hulks Out when he was already the size of a football stadium.
- In Desert Punk, desert gang leader Makoto has what's described as a case of "Hulk Syndrome." Insult his mother, 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.
- It's not just ANY insult to his mother that causes this either. No. You gotta say she has a fat belly button for him to really get angry.
- Only in the original version. In the English dub, calling his mother a dirty whore works too.
- It's not just ANY insult to his mother that causes this either. No. You gotta say she has a fat belly button for him to really get angry.
- In chapter 305 of Hunter × Hunter, Kid Hero Gon Hulks Out when Pitou admits that Kite is already dead and beyond any help. He turns into a muscular long-haired adult whose raw power rivals that of the Chimera Ant King. Overlaps with Dangerous Forbidden Technique since 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 Angel Cop, where the psychic Lucifer enlarges her muscles, going from silky-smooth to rippling in an instant.
- Never get Stella from Arakawa Under the Bridge in her bad mood, especially talking ill about Sister, you will regret it.
- Kenshiro from Fist of the North Star is a minor version- 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, not that it helps any.
- Rosario + Vampire: 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 Shapeshifter Weapon, whereas the big boss instead goes One-Winged Angel.
- Fairy Tail: such◊ is the effect of the Power Perfume in Ichiya's arsenal. Magic Pants are included,◊ of course.
- In Green Worldz, the female human hybrid does this by having wood branches surround her body when she starts getting a little serious.
- Parodied with a Running Gag in Tokyo Ghoul:Re. The so-called "Hulk Urie" is a fictional version of Urie, drawn by 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 with her creative presents.
- Naturally, the Trope Namer and Codifier is the Incredible Hulk.
- The writers of The Incredible Hulk Live Action TV series officially called it "Hulking Out."
- Sonic the Comic 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.
- One infamous moment in Archie Comics' Sonic the Hedgehog had a multiverse of Tails team up and fuse to become Titan Tails, which was a gigantic, beefed-up Tails, to battle Master Mogul.
- Loose Cannon, a Captain Ersatz of the Incredible Hulk in The DCU.
- In Wild CATS, the team's Genius Bruiser 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.
- This is also the case with Walter/Wallop from 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 World War Hulks and Hulked Out Heroes had several big name heroes Hulking Out after being exposed to an enemy superweapon to make them go on a rampage. Deadpool, several members of the X-Men, all of the Fantastic Four except Reed Richards, Thor (who seems to be weaker in this form), Spider-Man, and even Doctor Strange were all Hulk-ified. Naturally they all fell victim to The Worf Effect — and Hulk.
- Even She-Hulk Hulked Out even more in Avengers Disassembled: becoming larger, stronger and uglier as she went berserk over The Vision 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 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.
- Subverted and lampshaded in Invincible when Mark tries to hulk-out over 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." Then again, Mark does nearly kill Conquest afterward, so...
- It's not easy to make a Hulk desperate. Push Red She-Hulk far enough, though - say by overwhelming her with an army of supersoldiers - and she Hulks Out again, turning into a rampaging creature running on pure survival instinct.
- In recent years, Batman villain The Scarecrow has reacted to great rage or pain by involuntarily transforming into the hulking monster Scarebeast on some occasions. He does not seem to retain any memory of these interludes.
- In a story about the Justice League of America told by J'onn J'onnz, the Martian Manhunter himself went through a Hulking Out moment when the Blue Beetle and Booster Gold played a prank on him due to his addiction to 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 Captain America 2099 in Marvel's Secret Wars (2015) event and later becoming a canon part of Spider-Man 2099, 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 Great Lies To Tell Small Kids, which claims Banner only half-hulks when he's irritated (such as by being asked to do the dishes).
- A side-effect of Fauna's abilities in DC Nation. In human form? Technical Pacifist (downgraded a bit from Actual Pacifist) Granola Girl or New-Age Retro Hippie, and more support staff than combatant. Push her past the limit, though...
- Conversed in Calvin and Hobbes: The Series when Dr. Brainstorm and Jack witness Socrates' head transmitter going off.
- Papa Smurf in the Empath: The Luckiest Smurf story "Papa's Big Crush" when he inhales the "pheromone cologne" mixed in with his other chemicals, and in this state he goes after Smurfette.
- Thousand Shinji: When Asuka gets mad she transforms into a superpowerful, demonic-looking berserker: her body becomes bigger and incredibly athletic and muscular (while not sacrificing a single drop of feminity), her blue eyes become dark-indigo, her hair's colour becomes brass bronze and her skin's blood-red, and huge ram horns sprout from the sides of her head. When she dons that shape she becomes incredibly strong, fast, agile and nearly invulnerable.
- In the Pony POV Series, Dark World Arc, Angry Pie (the corrupted Pinkie Pie) has the Element of Rage and gets this power from it, making her stronger the angrier she gets. Which is an easy thing to do. She kept the power after her Heel–Face Turn until her death, at which point Rarity absorbs her Element and gains it. According to Loose Canon, a resurrected Gilda is the next Bearer of the Element after Rarity retires, and gains this ability.

Films — Live-Action
- Mark Ruffalo's version of The Hulk in The Avengers (2012) shows Banner's control is improved. He Hulks out twice: Once when in great pain, once again during the film's big battle, showing a measure of acceptance and control. In one scene, Banner strolls towards a massive Leviathan monster bearing down on the team. On being asked when he was going to get angry and transform, he wryly admits that he's always angry and proceeds to Hulk-out, without breaking stride, before punching out the monster in one blow.
- The League of Extraordinary Gentlemen. Dr. Jekyll does this when he turns into Mr. Hyde.
- In X-Men: Days of Future Past, '70s Beast uses a serum that allows him to maintain a balance between his human and mutant appearance. When he's angry enough, his mutation kicks in, and he returns to human form once he's calmed down.
- In 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."
Live Action TV
- A prize fighter in the Lost Girl episode "Raging Fae" keeps beating stronger foes because a Fae is secretly dosing him with a Hulk Out-inducing substance.
- Played for Laughs in The Young Ones. After receiving a merciless barrage of abuse from all three of his housemates, Neil does this in the Summer Holiday episode. Turns out it was actually an Indulgent Fantasy Segue, though it's a mystery what happened to his clothes...
- While werewolves in the Buffy the Vampire Slayer usually transform the day before, of, and after the full moon, when Oz learns to control the transformations he is then subject to Involuntary Shapeshifting when he feels strong emotions (like jealousy over Tara's relationship with Willow).
- This is how werewolves in Sanctuary work. Henry seems to be the first person to figure out how to control the changes (without drugs).
- Yet another werewolf example. In Big Wolf on Campus, Tommy would not only transform during a full moon, but also during times of extreme emotional stress... or arousal.
- One prank in Just For Laughs Gags 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.
- Warehouse 13 has the guys on a college wrestling team "hulk-out" when they take an energy drink that's "spiked," as it were, with the essence of a Viking berserker ladle. It's much more subdued than other examples, but there's a catch: If the guys drink too much of it...Let's just say they "flame on."
- If you torture a Friendly Neighborhood Vampire in Supernatural, you can force him to show his fangs and take revenge as Martin finds out in "Citizen Fang" (S08, Ep09).
- Going "full-on zombie mode" in iZombie is usually triggered either by immediate danger or hunger for brains. The zombie's eyes go 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).
- The Amazing Extraordinary Friends: Dr. Dominique Brioche suffers an nuclear genetic accident and transforms into the 50 ft. Atomic Bombshell whenever she gets angry.
- Possibly the Ur-Example is Cúchulainn of Celtic Mythology; in battle he would undergo something called ríastrad or battle frenzy, in which he would transform into something not unlike an Eldritch Abomination in its hideousness and ferocity. This form was only beaten once, when he was approached by a group of nude women. He modestly averted his eyes, whereupon the men snuck up on him and dunked him in a barrel of water, which exploded on contact. A second barrel boiled away, and the third became pleasantly warm before Cúchulainn resumed his normal form.
- Kali in Hindu Mythology is the hulked-out form of Durga/Parvati.
- Werewolf: The Forsaken has Death Rage, where a werewolf will automatically transform to his "war form" and go on an unstoppable rampage. It's either triggered through pain or anger (and depending on your Karma Meter, that anger can range from "one of your packmates just got killed" to "someone talked sass to you").
- Similarly, vampires have Frenzy, which is triggered by stimuli such as anger, fear or hunger. And unlike in the above example, getting sassed at is a perfectly normal stimulus for Frenzy. There's a reason everyone stays polite at Elysium...
- And their predecessors in the old World of Darkness can also frenzy in many of the same situations.
- In the Arthaus edition of 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.
- In Breath of Fire IV, Ryu first transforms into his Kaiser form after he witnesses Captain Rosso kill some innocent children and send an invincible monster after him and his friends. Ryu then kills both the monster and Rosso, and it takes a Cooldown Hug from Nina for him to regain his senses. Afterward, he can transform into Kaiser at will, but it cannot be controlled until you finish a certain sidequest.
- Bowser only reaches his highest level of power in Mario & Luigi: Bowser's Inside Story after being (otherwise fatally) crushed, with a little help from the Mario Bros.
- In Vampire: The Masquerade – Bloodlines, 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 the original Fatal Fury, Tung Fu Rue will transform into a larger, more muscular version of himself after taking too much damage (although he will change back after taking more). Future games restricted this to the use of his super moves. More recent games that feature him reveal that he's not actually transforming at all, but that the muscular version of Tung is actually a Battle Aura of sorts.
- In Amagon, the titular player character transforms into the Hulk-like Megagon for Super Mode.
- One World of Warcraft 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 "You Wouldn't Like Me When I'm Angry" if you click on them enough.
- Anders in Dragon Age II, whenever he is overtaken by the Spirit of Justice inhabiting him.
Justice: You will never take another Mage as you took him!
- Despite rage being a main theme, Asura from Asura's Wrath primarily averts this. He does, however, grow bigger arms that pack at least a a thousand times more power in them in his Berserker form, his Mantra form and his Destructor 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).
- Grimlock's alternate mode is somewhere between this and Super Mode. In-game, the transformation isn't involuntary but 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 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.
- While not shown, Leo Hartwig's in Bioshock2 transformation into a Brute Splicer involves this. It is heard in his Audio Diary "Field Trial #1".
- In 1977: The Comic: When the normally easy-going Bud has had just about enough and transforms either into or out of his alter-ego Budette.
- MAG ISA — Kyle turns into this chunk of muscle after injecting himself with green roids
- Fug from Pewfell is normally a Gentle Giant... until he gets angry, then he turns into something resembling an Eldritch Abomination with arms.
- Shrinking Violent of Everyday Heroes has her transformation triggered with a blow to the nose. She can be snapped out of it via massive amounts of sugar. Unfortunately 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 even her strongest teammate can't hold her down.
- Sarah of Peter Is the Wolf. As a new Thrall (a were who's created, rather than born), she tends to transform when ever 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 sexual gratification.
- Marty Monster from The Adventures of Dr. McNinja, "Monster Mart". At the start, he'd been having problems with his transformation to and from his monster form, until he gets stuck halfway. At the end, seeing Dr. McNinja in mortal peril is enough to knock down his psychological barriers and allow him to grow bigger than ever before. He inherited this from his father; the problem with his father (aside from always looking down on him) is the fact that he's a Steven Hawking Expy, and so every time he transforms he falls over and left naked until he shrinks back down.
- Sweater Puppy and The Incredible Cunt from The Magnificent Milkmaid. Both turn into giant, large breasted 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").
- Prozac of Bear Nuts goes HULK SMASH after a prolonged time off his meds.

- The title character in the Heroes Unite Fury story.
- Lung, a villain from the web serial Worm, grows bigger, stronger, more invulnerable and less human-looking the longer a fight goes on.
- Crimson of the Slaughterhouse Nine becomes incredibly strong and durable when he drinks human blood.
- In the 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 The Venture Bros. Doctor Venture once thought Hank to be blessed with "retard strength" but was mistaken.
- South Park
- Parodied in the episode "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 Jesus takes HGH at the end. The scene that follows that has to be seen to be believed.
- On Jimmy Two-Shoes, Heloise spends an entire episode in a Sweet Polly Oliver 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, the real Heloise shows up. It seems Herman is her real cousin, and they made him mad...
- Katie Kaboom from Animaniacs.
- Also, the Brain in the Pinky and the Brain segment "Brain Meets Brawn".
- The eponymous character of Kaeloo goes through this Once per Episode.

- Fuzzy Lumpkins in The Powerpuff Girls episode "Fuzzy Logic".
- My Little Pony: Friendship Is Magic: In the episode "Power Ponies", when the cast gets sucked into a comic book, Fluttershy gets this as her superpower.
- Spike had a similar transformation into this in "Secret of My Excess".
- King Sombra seemingly underwent this during his imprisonment in "The Crystal Empire".
- Lord Tirek gradually invokes this the more he uses his Mana Drain in "Twilight's Kingdom".
- In the Samurai Jack episode "Jack and the Smackback", Jack's first opponent is a man-ape creature named Gordo the Gruesome who does this after he gets angry enough; Jack still beats him.
- Likewise, the titular goofy dumb beast from "Jack and the Creature" undergoes a frankly horrific transformation into a gargantuan, crimson-furred razor-sporting abomination after Jack starts getting smacked around.
- About halfway through Captain Simian and the Space Monkeys, Gor-illa gets an upgrade from an Unstoppable Rage to this at the hands of recurring antagonist Ajax, causing him to transform into the berserk King Kong expy Gormungus whenever his rage builds high enough.
Spydor: Well, this dog wants to eat you!
- 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 protests that he doesn't want to eat a dog, the alien grins a toothy grin... and then turns himself inside out, transforming into a hulking monstrosity that vaguely resembles a skinned gorilla with spikes growing out of it.
- In the The Adventures of Jimmy Neutron: Boy Genius 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 and combined with the stress handling the other characters plus the constant mockery that Jimmy goes under in this episode, only triggers the Hulk Out.
