* ''Anime/DragonBallZ'': Gohan. Though suffice to say, nearly every Saiyan character qualifies at one point or another. But Gohan is the outlier, because his potential since the beginning was defined as Unstoppable Rage.
** Goku's first Super Saiyan transformation also qualifies. He's out of power, then has to watch Piccolo, his rival and valuable ally at the time, and his best friend, Krillin, both get attacked by Frieza, with Krillin murdered outright -- and then, just to be even more of a monster than he already is, Frieza just ''has'' to threaten little Gohan as well. This pushes Goku over the edge.
** In the villains: Frieza, Super Buu and Kid Buu. What makes it more disturbing that the unstoppable rage in these villains is combined with [[{{Sadist}} extreme sadism]].
** Broly, the original Super Saiyan, is Hulk without the green skin. As he gets madder, his power increases, but sooner or later he has to cool off.
* ''Anime/SonicX'' in its third season had the eponymous character Sonic at one point absorb negative energies from fake Chaos Emeralds which unleashed when he became angry upon seeing his friends badly beaten and at risk of execution. The resultant fight involved him beating the everloving crap out of two robots specifically designed to be difficult to defeat. His long-time nemesis, Dr. Robotnik/Eggman, convinces him to stop his rage.
--> [[SlasherSmile "Alright then, let's]] ''[[SlasherSmile test it out!"]]''
* ''Manga/{{Naruto}}'' has the Nine-Tailed Fox form that Naruto engages during instances of extreme emotional disturbance. The first time is when Sasuke defends him from Haku's lethal technique, followed by several later instances when Naruto is angered. The Rage will inevitably cause Naruto's lifespan to be shortened, due to his constantly dying/regenerating cells while the form is active). Also, if Naruto completely loses it, the Fox will take possession of his body. [[spoiler: No longer need to worry about it since he has full control over Kurama.]]
** Orochimaru invokes this trope. And boy does he not learn his lesson.
* For ''Anime/CodeGeass'', with all a lot of characters being over-protective of another, this happens a number of times. Suzaku stands out particularly, despite being two-thirds pacifist and displaying warrior-like grace, the moment when [[spoiler: he witnesses Euphy being shot]] causes him to go berserk, charging through the battlefield and through two mechas that posed a serious threat to him [[spoiler: in order to rescue Princess Euphemia]] following which he abandons the battle entirely. This later [[spoiler: seemingly pushes him past his DespairEventHorizon]].
* ''Manga/RanmaOneHalf'': A more comedic use of the trope, if Ranma's fear of cats reaches a critical point (especially when surrounded by them and unable to get away), his mental state becomes like that of a cat. He can only use the Neko-ken (cat fist) when in this state, which manifests as an increase in speed and agility, and the ability to attack enemies (or anything else that annoys him) with invisible claws sharp enough to slice through seemingly anything. But with his mind and personality those of a common cat, this also becomes an example of SanityHasAdvantages: Ranma is distractable, unfocused and generally stupid in this mode, meaning that he can be outthought fairly easily. In this state, Akane finds herself the KidWithTheLeash, as Ranma will joyfully savage [[GenderBender his/her]] own JerkAss father without a second thought, but he curls up with her like a happy kitten, even though he is insistent that SheIsNotMyGirlfriend.
* In ''Anime/PrincessMononoke'', this happens to Nago [[spoiler:and almost to Okkoto]], who are rhinoceros-sized wild boars to begin with. Their rage [[spoiler:comes from their whole tribes being slaughtered by humans and]] only ends when [[spoiler: they are killed]].
* Subverted in ''Manga/{{Eyeshield 21}}'' numerous times, such as when [[spoiler: Tetsuma charges at Gaou after he severely injures Kid and is still soundly defeated]].
* In the finale of ''Anime/GaoGaiGar'', after [[spoiler: the final super Zonder's (Mikoto) barrier is weakened, you would expect Guy to wrap it up and finish the fight quickly. Instead, he ''[[CurbStompBattle completely brutalizes]]'' the Zonder, ripping off one of its wings, stomping on its head, punching its arms off. To top that off, he didn't even bother with [[FinishingMove Hell and Heaven]], he just aimed at the core and ripped it out. All of this while [[ScreamingWarrior screaming in anger]]]].
* ''Franchise/{{Gundam}}'':
** In ''Anime/MobileFighterGGundam'', this is initially played straight with Domon Kasshu's Shining Gundam and its Super Mode. He even yells "Take this! My love, my anger, and all of my sorrow!". This is later subverted as he finds out this is the "imperfect" mode. His more powerful Hyper Mode can only be used when he is in a [[TranquilFury completely zen state of peace, calm, and focus]].
** See ''Anime/MobileSuitGundamSEED''. See Kira get angry. See Kira go crazy, and completely disable all of his enemies in seconds.
*** That's not Kira angry. Go watch the episode where [[spoiler: He and Athrun succumb to their rage and try to kill one another.]] Both of them convey their rage very well with the sheer brutality of their attacks. No more hesitation, no more clever tricks. Their minds are set on the same part of the dial: "Two men enter, one man leaves."
** To say nothing of Shinn from ''Anime/MobileSuitGundamSeedDestiny''. It doesn't work very well for him, since when his rage really gets out of control, Shinn starts to forget about [[CombatPragmatist the outside-of-the-box tactics that made him so dangerous in the first place]]. He'll plow through hundreds of normal enemies while [[TheBerserker berserking]], but another AcePilot will usually have an easier time of stopping him.
** In ''[[Anime/MobileSuitGundamWing Gundam Wing]]'', [[TheStoic Heero]] enters an Unstoppable Rage during his first use of the Gundam Epyon because of the ZERO System's side effects.
** Setsuna F. Seiei from ''[[Anime/MobileSuitGundam00 Gundam 00]]'' generally keeps very good control of himself if he gets mad, but he does have one case of pure rage: during the intervention in Azodistan, he witnesses a scene that reminds him of the horrific war he participated in [[ChildSoldiers as a child]], which causes him to snap and go completely ballistic on the attacking Suits. Most of the time, in ''Gundam 00'', blind rage = quick death for pilots, be they flying a Gundam or not.
*** A slight variation on this would be Allelujah Haptism. Normally, he's a calm, calculated Gundam Pilot, and generally the most relaxed of the bunch (for example, he never once fought any of the Gundam Throne Units, at least not on-screen, and didn't even seem to give a damn about their activities, even when he other Gundam Pilots went to fight them. Earlier, he also endangered the entire mission just to save some civilians while HRL-backup troops arrived). However, his calm only lasts until someone else capable of using Quantum Brainwaves gets too close, especially HRL Ace Pilot Soma Peries. Then his psychotic alter ego takes over and brutally slaughters everything in sight that doesn't get away. Finally, by the end of Season 2, he learns to actually control this, which is heavily exploited during the Movie, not limited to having 2 Super Soldiers with 3 personalities in total piloting 1 mech that gets stronger because it's piloted by super soldiers.
** In ''Anime/MobileSuitZetaGundam'' [[TheRival Jerid Messa]] normally CantCatchUp to [[TheHero Kamille Bidan]]. However, anytime Kamille kills someone Jerid cares about it sends Jerid into this mode and makes him all but impossible to beat.
* Fuyuki Hinata in the manga/anime ''Manga/KeroroGunsou'' becomes so frightening when angry that all other characters shrink back in horror. It takes a very serious personal offence to rile him.
* ''Anime/NeonGenesisEvangelion'' has Eva-01 going berserk against Angels multiple times to devastating effect, the most terrifying instance landing up with the Eva [[spoiler:eating one of the angels]], Shinji himself going berserk against Shamshel, and Asuka when she [[spoiler:tears through the Mass Production Evas]]. In fact [[spoiler: it's the soul of the pilot's mother inside the Eva that goes into an unstoppable rage whenever her child is in danger, and Asuka and her mom go berserk together]].
* Ayato Kamina from ''Anime/RahXephon'' seems to be quite capable of working himself into an unstoppable rage in combat. His common method of combat is very much the [[ScreamingWarrior raging badass screaming his way into battle]], and as a general rule, the second Ayato releases a soul-tearing scream of pure rage, the enemy Dolem is about to die.
* The [[CaptainErsatz slightly related]] [[TabletopGame/CthulhuTech Engels]] and [[Manga/{{Guyver}} Tagers]] get a little irritated if you knock out their pilots, and Engels become enraged if the wrong pilot gets in the cockpit. During this state, they'll try to kill anything that looks remotely threatening that isn't of the same type of being. They don't gain strength or do more damage, but they make all skill rolls as if they had three points in each skill, and don't suffer wound penalties.
* Chimchar in an episode of ''Anime/{{Pokemon}}''. That was enough for Paul to try everything he could to bring out that power again.
** After being knocked unconscious by Paul's Ursaring in a later battle, the true extent of Chimchar's power is unleashed and it needs a CooldownHug when it doesn't go back to normal. This unnatural power has been explained as its ability, Blaze.
*** Later on, after it's evolved into Monferno, it does this again, and requires another CooldownHug from Ash in order to calm down. [[spoiler:Then it evolves into Infernape, after which it's able to control the Ability.]]
*** In the Sinnoh League Infernape once again activates Blaze, ''and it looks like he's going Super Saiyan while doing it.''
** Also seen with the Pokemon Mankey, and more so with its evolved form Primeape, which has a HairTriggerTemper and goes into an Unstoppable Rage at the drop of a hat.
** PlayedForLaughs with Jessie, especially [[BerserkButton when her hair gets damaged]]. Poor Seviper [[NoHoldsBarredBeatDown found out the hard way,]] and it should be noted that that same Seviper was proving to be a difficult for for Ash and co. earlier in the episode.
** But none of the above hold a candle to a pissed-off [[PhysicalGod Mewtwo.]]
* ''Anime/YuGiOh'' naturally turned this effect into a card, "Berserker Soul", and had it used by Yami Yugi during one of his own moments of Unstoppable Rage. "DORO! MONSUTAA KAADO!"
** The full story: sometime after Yugi's soul is taken by the Orichalcos, Insector Haga (Weevil Underwood) taunts Yami by tearing up a card in front of him "as a joke", claiming Yugi's soul was in it and tearing it up [[DeaderThanDead erased him]], and Yami ''completely loses it''. Even worse for Haga: since a duel within the Seal is effectively a Shadow Game, he ''physically felt each and every blow Breaker dealt to him.'' The true chill-down-the-spine moment, however, comes shortly after he reveals his ruse:
-->'''Yami:''' Wash your neck and wait, Haga.
** That order was traditionally given to prisoners before being executed, meaning Yami had gone past saying "I'm going to kick your ass" and issued ''a death sentence'' to Haga, which he then proceeded to carry out with ''brutal'' efficiency.
* In full swing for [[BreakTheCutie Judai]] by Season 4 of ''Anime/YuGiOhGX'' -- if he says "ThisIsUnforgivable".
* In ''Manga/SaintSeiya'', Phoenix Ikki goes into unstoppable rage mode when his master, Guilty, kills his MoralityPet Esmeralda ''[[KickTheDog specifically]]'' [[MoralEventHorizon to provoke him]] into fighting. It ends very badly for Guilty.....very.
* Subaru of ''Anime/MagicalGirlLyricalNanohaStrikerS'' is normally a [[GenkiGirl happy and energetic sort]]... until you hurt and threaten to take away her sister, that is. Then her [[GlowingEyesOfDoom eyes go glowy]] as [[ChunkyUpdraft rocks around her float from residual energy]]. Her [[http://www.youtube.com/watch?v=stcdeabi8WU resulting rampage]] sent two of the QuirkyMinibossSquad scurrying and put one of their strongest and most experienced members out of commission for the rest of the season.
** Also, Vita in ''[[Anime/MagicalGirlLyricalNanohaAs A's]]'' after [[NiceHat her hat]] got [[BerserkButton damaged by Nanoha]].
** [[SummonMagic Caro]] is no slouch either. The response when she found that [[BerserkButton her squad's home is destroyed]]: she summons '''''[[PhysicalGod Voltaire]]'''''. ("Godzilla with wings" wouldn't be an inaccurate description.)
* Tsukasa Domyoji from ''Manga/HanaYoriDango'' rules the elite private school he attends not because he's an absurdly rich pretty boy but, because when pissed off (and he has an infamously short temper), he will try to kill anyone in his path. And he's the male romantic lead; the reason why he's at first interested in the [[{{Tsundere}} female lead Tsukushi Makino]] is because [[LoveAtFirstPunch she's the first Eitoku student who defies him openly]], to the point of [[SlapSlapKiss bitchslapping him often]].
* ''Manga/{{Berserk}}'' put it in the title, so it's a major part of the series.
** A particularly notable example from the anime comes during the Griffith rescue arc, when Guts finds out just [[ColdBloodedTorture what had been done to Griffith]]. After holding him for a few moments with tears in his eyes, he ''smashes through a thick wooden door'' to take out the bastard who had tortured him, and then proceeds to live up to the name of the series by going on a rage-fueled killing spree on every last [[{{Mooks}} Midland guard]] standing between the Hawks and the way out. They don't call this guy the "Hundred Man Slayer" for nothing.
** The most extreme example came when the Eclipse happened, when [[spoiler:Guts sees the only other survivor of the massacre, his lover Casca, naked, in the grip of a tentacled Apostle and surrounded by demons, he goes flying into an extreme rage and [[FoeTossingCharge goes barreling toward the horde]], only to have his left arm clamped down on by another demon. Then, [[FromBadToWorse to make matters worse]], newly made demon lord Griffith-turned-Femto flies down and [[IHaveYouNowMyPretty begins raping Casca]], which serves to piss Guts off to the '''very''' extreme, and when his sword breaks against the flesh of the demon who is holding him captive, so embroiled in rage is he that Guts doesn't so much as to even twitch at the pain of [[LifeOrLimbDecision HACKING OFF HIS OWN ARM TO ESCAPE]]. [[IAintGotTimeToBleed He's covered in his own blood]], [[SayMyName screaming Griffith's name]], [[BlankWhiteEyes white-eyed with fury]] [[HeroicResolve and everything else.]] [[HopeSpot Nothing can stop this fucker now]]]]. [[StuffedInTheFridge Unfortunately]], [[SubvertedTrope Guts' rage is]] [[ForcedToWatch anything but unstoppable]], [[BreakTheCutie and isn't enough]] [[GoMadFromTheRevelation to save Casca]].
* It's generally not smart to get Wolfgang Grimmer of ''Manga/{{Monster}}'' angry. It's generally not ''survivable'' either.
* In ''Manga/ElfenLied'', the main character Lucy is almost constantly in this state when she isn't in her alternate personality Nyu, due to a lifetime of almost constant abuse, deprivation, and trauma. Considering that her powers as a diclonius are a recipe for an all-out gorefest, triggering the Lucy persona may well be ''the last thing you ever do''.
* When [[GhostInTheShell the Major]] is beating the crap out of you with a stoic expression, she's actually just toying with you until you realize the futility of trying to fight her. If you somehow manage to really make her pissed, it will be very obvious, but you will probably never get the chance to fully comprehend what's happening to you. This woman's normal range of expression consists entirely of ''stoic'' and ''smiling politely''. When her anger is showing, the point of reasoning with her is long over. And being a cyborg, she doesn't even care if she gets limbs torn off or her body crushed, making her truly unstoppable. The only two opponents who ever defeated her were inside HumongousMecha, which she [[DidYouJustPunchOutCthulhu attacked bare handed]].
* In ''Manga/SlamDunk'', the first thing HeavySleeper Kaede Rukawa clearly says is "My name is Rukawa Kaede, I'm a freshman, ''and [[ThisIsUnforgivable I will never forgive]] whoever wakes me up when I'm napping''." Cue to him beating up the gangsters who woke him up from his nap.
* Several players in ''Manga/ThePrinceOfTennis'' have a penchant for injuring their rivals during games. The most infamous ones are Akaya Kirihara from Rikkaidai, Jin Akutsu from Yamabuki and Kippei Tachibana from Fudomine. Subverted in Tachibana's case: [[spoiler: after he seriously injures his [[HoYay best friend and teammate]] Chitose, he becomes TheAtoner and refuses to use violent tennis anymore. Which makes him easy prey for Kirihara's Devil Mode later.]]
* ''Manga/FistOfTheNorthStar'': People who piss off Kenshiro (usually by [[KickTheDog going too far in their cruelty to others]]) usually don't live to tell the tale. In fact, if they do, [[CatchPhrase they're already dead]]. This is at least explained in the series by the fact that his fighting style is designed to increase in power proportional to exactly how angry he is. At normal levels of anger, he can break concrete with his fists. When he is at full power, he can ''make a tank explode'' by ''punching the driver''.
* If you're an [[TheHeartless Akuma]], and you tick off Allen Walker of ''Manga/DGrayMan'' too much, you're likely to make his [[EmpathicWeapon Innocence]] upgrade. Or you might make it angry. That would be a bad thing.
** Think about it in this way: a permanent upgrade to his weapon will only hamper your goals in the long run, but if you get the weapon mad you will lose so much of your force, that the scales will probably balance.
* Kazuya Ryuuzaki in ''Anime/{{Daimos}}'' is generally an all around nice guy, especially towards the Earthlings, and he tries to be good for some NotSoDifferent aliens. But after seeing [[GeneralRipper Miwa's]] racism towards innocent aliens too many times... he snaps, jumps dodging an attempted shot from Miwa and starts beating the crap out of him using Karate (thankfully on foot, rather than stomping him with the eponymous mecha) while screaming that Miwa was actually ''worse'' than the aliens (which is actually true). Kyoshiro and Nana managed to stop him after hearing that Miwa would be arrested for his crimes, but even after being restrained, Kazuya cannot stop to scream at them telling them to stop restraining him. This also gets taken to VideoGame/SuperRobotWars Advance, done with full amounts of [[Awesome/SuperRobotWars awesome]].
* Both Takato and Guilmon of ''Anime/DigimonTamers'' simultaneously go into an uncharacteristic rage upon [[spoiler: the death of Juri's Leomon]], with [[DeadlyUpgrade disastrous results]]. Guilmon and his evolutions even have a hazard symbol to hint that you really shouldn't piss him off.
* T.K.'s/Takaishi Takeru has moments of intense anger in ''Anime/DigimonAdventure02''. The first time th anger was shown has him physically beating the Digimon Kaiser while shrugging off the blows of the latter's whip. And [[TranquilFury he looks and talks so damn calmly]] [[DissonantSerenity just before]] [[BewareTheNiceOnes doing that.]]
* In the very final chapter of ''Anime/TekkamanBlade'', [[spoiler: Blade's brain breaks down completely because of his DeadlyUpgrade. Right when it looks like we're all doomed, he suddenly lets out a roar and zips off to the moon to have a nice, dramatic final battle. Did he get better? Nah. It's just that a single aspect survived the complete destruction of his entire personhood - his rage toward the Radam for taking away his family.]] It really puts the "unstoppable" in Unstoppable Rage.
* In ''Manga/ChronoCrusade'', Chrono has moments when his BerserkButton is pressed where he taps into his demonic power and starts to attack indiscriminately. In one particularly bad moment of this, he sets part of a city ablaze and [[spoiler:nearly kills Rosette because of the massive drain on her soul]]. Which sends him into a HeroicBSOD afterwards. A major key in the events leading up to the climax is Chrono learning to control his rage.
* ''Anime/PrincessTutu'' has an example of this trope, but not in with the character you'd expect. Is it Fakir, who prides himself on being the Knight? Nope. Is it Mytho, the heroic Prince from a fairytale? Not him, either. It's actually Autor -- a nerdy, Drosselmeyer-obsessed scholar. [[spoiler:When Fakir's hands are nearly cut-off by the Bookman trying to stop the story, Autor flies into a rage and defeats the axe-wielding man using only his bare hands.]] Not nearly as impressive as some of the other examples on this page, and it only appears briefly, but it's still surprising considering the sort of character he's portrayed as.
* In ''Manga/{{Mai-HiME}}'', this happens to '''Mai''', [[AllLovingHero of all people]], when [[spoiler:Mikoto (accidentally) ends Takumi's life under the [[BrainwashedAndCrazy influence]] of her ''own'' Unstoppable Rage.]] She grits her teeth so hard that [[BloodFromTheMouth blood starts to form]], and summons her CHILD to attack. [[spoiler:Mikoto gets better... [[FaceHeelTurn but not in the way Mai expected]].]] PROTIP: ''Never'' anger a girl with an enormous pet dragon.
* In ''Manga/{{Hellsing}}'', [[spoiler: Zorin Blitz kills Pip as he tries to carry a blinded and severely wounded Seras to safety. He requests for Seras to drink his blood so "they can defeat them together" just before he dies. Filled with intense sadness which quickly becomes rage, Seras fulfills his last wish and her true vampiric abilities awaken. She then proceeds to go batshit insane and slaughters Zorin's mooks, and finally grinds Zorin's head on the wall like a cheese grater.]]
** Also during the Valentine Brothers attack on the Headquarters.
** Alexander Anderson from the series seems to fit this trope as well when he is in combat, typically demonstrating nothing but sheer joy at the prospect of battle. He attacks Integra, a high ranking British official who didn't even want to start a fight, head on, killing her bodyguards and decapitating one of them before threatening to paint to walls with her blood. He runs into gunfire without even trying to dodge and due to his augmentations is able to slaughter hundreds of undead mooks without any difficulty. In the TV version, at one point he gets both of his arms shot off. He simply kneels to the ground and grabs his knife with his teeth, and then proceeds to run at his opponent with it while he's still being shot at.
* Subverted? In a {{Shonen|Demographic}} anime? Unnatural! But in ''Manga/ShamanKing'', rage clouds your mind, and causes you to squander your energy. It's specifically considered something to be avoided.
** Demonstrated quite well in the Yoh vs. Faust VIII fight. Faust taunts and enrages Yoh from the start of the fight by harming Manta, and when Yoh is on his last legs, his last-ditch strategy is to punch Faust's BerserkButton as hard as he can. And it probably would have worked if Yoh had had just a little more furyoku to spare.
* In ''Manga/{{Gintama}}'': Not exactly conscious rage, per se, but it is brought about by rage. In her fight against Abuto, [[spoiler:Kagura loses all control against her Yato instinct and flies into what can be fairly called an Unstoppable Rage - though the look on her face says she's actually enjoying it in a detached, psychotic way.]]
* ''Manga/BusouRenkin'' has a good chunk of rage, with [[spoiler: a Victorized Kazuki duking it out with Victor.]] There's also Tokiko, who pumps rage through her veins instead of blood.
* In ''Anime/TengenToppaGurrenLagann'' Simon flies into one in the middle of taking over the Dai-Gunzan when [[spoiler:Kamina appears to have died]]. He then releases so much Spiral Energy that the whole ship starts to glow, blows all the {{Mooks}} out of the ship, and he ''sets off a nearby volcano''. It took [[GetAHoldOfYourselfMan a whalloping]] from Kamina to get him out of it.
* ''LightNovel/FullMetalPanic'': In episode 5, Sagara and Tsubaki ''really'' piss off the school janitor, who transforms in to a [[ChainsawGood chainsaw-wielding]] monstrosity that [[OffhandBackhand easily fends off]] their combined attacks, swallows hand grenades, and chases them around the school like puppies.
* Hamel in ''Manga/ViolinistOfHameln'', when he transforms into a monster.
* ''Manga/OnePiece''. Pressing any of the [[BewareTheNiceOnes Straw Hats']] {{Berserk Button}}s will inevitably lead to this.
** Do not anger Luffy enough to make him take off his hat. God help you if you make Luffy take off his hat. How can you do this? Insult anyone's dreams, hurt his friends, mock anything to do with a pirate's pride, threaten anyone close to him...
** And if you want to make it several billion times worse, if you [[HatDamage step on Luffy's hat or do anything to damage it]], 2 steps will follow:
-->'''1.''' Luffy will call you a bastard.
-->'''2.''' Luffy will kick your ass from here to next Wednesday.
** Exemplified in ''Anime/OnePieceFilmStrongWorld'', where the BigBad manages to get Luffy the angriest he's been in a long time.
-->'''Luffy:''' ''You think after everything you've done to my friend, and my sea, that I'm going to let you get away with all of this?!!''
** To put it in perspective, the character Luffy said that to had spent over twenty years developing his plan, and it was so far along that the only way it could fail is if he happened to blab too many of his secrets to someone who would oppose it, allow that someone to discover the remaining secrets, bring that someone to his home base, and refrain from killing that someone when he had the chance. But even if a someone was armed with all that, they would need to have an ''absurd'' amount of power to stop him. And who does he do that to except for the Straw Hat Pirates? And he made it infinitely worse by [[BerserkButton kidnapping their navigator]] whose meteorology skills are unrivaled in that world in order to ''remove the only possible threat to his plan.'' He learned the hard way that the unpredictable cyclones of the Grand Line were ''nothing'' when compared to the Straw Hats' Unstoppable Rage.
** Tell Sanji that his chivalry is nave, that he can't protect anyone, mock his status as a chef, ''waste food'' or insult a beautiful lady in his presence. For maximum effect, do all of the above at the same time.
** Although this could also go under TranquilFury, there's also [[spoiler: Whitebeard]] in the War of the Best, where after [[spoiler: everyone witnesses Ace's death and despite sustaining heavy injuries from being shot, stabbed, slashed, burned and having half his face melted off, he defeats ''[[MagmaMan Akainu]]'' in 2 hits, the second hit destroying most of Marineford and separating the pirates and Marines with a giant chasm.]] In short, never, ''ever'' piss the old man off.
** Recap of the past few {{Big Bad}}s. Number 1: Arlong. Killed Nami's mother and enslaved her and her home island. Promised to free them if Nami paid him a hefty amount of money. Utilized LoopholeAbuse to ensure she doesn't get the amount after eight years of hard, hard work. Mocked her and provoked her entire village to attack him in what would inevitably be a CurbStompBattle with everyone she loved ending up dead. The culmination of this? Nami bursts into tears, and asks Luffy for help. He and his other three crew mates march off to Arlong Park, and a couple of hours later, Arlong is unconscious and half-dead beneath the rubble of what used to be his base, and all of his henchmen aren't much better off.
** Then we have Enies Lobby. Renowned as the World Goverment's Judicial Island and one of their three centers of power, the place has 10,000 soldiers and a group of superhuman assassins to ensure that any criminals taken there are beyond all hope of saving. The assassins, [=CP9=], forced one of the Straw Hats to join them there on penalty of having the rest of them obliterated. When the other Straw Hats found out, they defied all odds and invaded Enies Lobby. For centuries, the place stood as a stronghold, symbolizing the World Government's power and authority. In the space of a single night, the Straw Hats' invasion transformed it into a burning, ruined wasteland.
** Most people who made the mistake of challenging the Straw Hats provoked their Unstoppable Rage and were unable to prevent the consequences, to the point that after the TimeSkip, [[spoiler:Donquixote Doflamingo, one of the most powerful pirates in the world, TheDon of the entire New World, and a guy with connections to the World Government in the highest possible places, is taking care not to underestimate them.]]
* Roberta from ''Manga/BlackLagoon'' normally spends her days as a bad maid, but if you kidnap or kill her masters, she will hunt you down through single photographs and kill you. You have a slight chance of surviving if you are a member of the Green Berets, otherwise you are ''dead''.
* Shortly after Kiyomaro of ''Manga/ZatchBell'' comes BackFromTheDead and completely wipes the floor with his opponents, one of them taunts Kiyomaro with mention of his fallen allies and receives an epic beating with epic use of DemonHead on Kiyomaro's part.
* Ryoma from ''New Manga/GetterRobo'' flies into a berserker rage near the end of the series, after absorbing an enormous amount of [[RuleOfCool Getter Energy]]. The character was already known as [[FanNickname "Batshit Ryoma"]] among fans due to his [[SlasherSmile crazy expressions]] and {{Determinator}} status, so the idea of him having an "Unstoppable Rage" mode distinguishable from his regular personality seemed impossible. [[UpToEleven They found a way]] [[http://img353.imageshack.us/img353/3568/snapshot20090103195309df0.jpg]].
* Miu gets this when she finds her friends [[spoiler: badly beaten by Shou Kanou]] during the D of D arc in ''HistorysStrongestDiscipleKenichi''. How does Kenichi snap her out of it? ''By groping her chest''. Which was apparently a ''technique'' that [[DirtyOldMan Ma Kensei]] taught him.
* Bado from ''Manga/DogsBulletsAndCarnage'' goes into Unstoppable Rage whenever he has a nicotine fit and can't find cigarettes.
* Negi Springfield of ''Manga/MahouSenseiNegima'' goes into one of these when [[spoiler:he finally meets the demon who [[TakenForGranite petrified]] his [[DoomedHomeTown home town]] on that [[SnowMeansDeath snowy day]]]]. Actually a subversion, since he almost meets the same fate. It's only after collecting himself that he mixes it with DissonantSerenity and starts kicking ass.
** It happens again when [[SmugSnake Kurt Godel]] [[IShallTauntYou starts taunting]] Negi about his past. [[spoiler: The fact that Kurt claims to be responsible for Negi's DoomedHometown, combined with the fact that Negi's BlackMagic is starting to get out of his control means that [[SuperpoweredEvilSide bad things are starting to happen]].]]
** Yue and Beatrice don't take it well when one of the demons erases [[ClassRepresentative Emily]].
* ''Manga/{{Bleach}}'':
** In the earlier parts of the manga, pushing Ichigo too far was an invitation for his [[SuperpoweredEvilSide Inner Hollow]] to come out and play. Eventually, he's driven into an unstoppable form of pure instinct as a result of Orihime being left vulnerable to Ulquiorra. This results in both Ulquiorra and Ishida (who tries to calm Ichigo down) to take the full brunt of Ichigo's state.
** When Captain Aizen appears to have been murdered, it's Hinamori who finds the body. Convinced the grinning Gin is the culprit she flies into an Unstoppable Rage, causing one of her best friends, Kira (Gin's NumberTwo) to step in to defend his captain. Even then, Hinamori won't stop, calm down or see reason and it takes the intervention of another captain to get the situation back under control (by arresting both Hinamori and Kira).
* ''Manga/OmamoriHimari'': Himari has one of the HeroicBSOD variety [[spoiler: Yuuto appears to have been killed by her opponent.]]
* ''Manga/WolfsRain'' - Toboe + Walrus
* Edward in ''Manga/FullmetalAlchemist'' goes into one of these when he finds that [[spoiler:Shou Tucker, an alchemist famous for making chimeras, turned his own ''wife'' into one, and then later turned his '''daughter''' and his dog into one. Shou makes it worse however, by provoking Edward about the use of human lives, and saying that they aren't so different, leading Edward to continually scream "YOU'RE WRONG!", whilst punching him repeatedly.]] Ouch.
** When Al [[spoiler:sacrifices himself to give Ed his arm back]], Ed goes berserk on Father Homunculus.
** Al almost does this too.
-->'''Alphonse:''' "[[spoiler:Mister Tucker]], one more word out of you... and ''I'll'' be the one to snap."
** Riza also goes into Unstoppable Rage when she thinks [[spoiler:Lust managed to kill Mustang,]] and promptly empties her gun's magazine into her, reloads and repeats. Several times. Worth noting because it is a subversion rather than a straight portrayal, as [[spoiler:when she's run out of bullets, she collapses and cries, while Lust gets back up after shrugging off the barrage without breaking a sweat]].
** When Mustang finally finds out that [[spoiler:Envy killed Hughes]].
--->'''Roy Mustang:''' "[[spoiler:That's that... you killed Hughes..... that's all I needed to know... You don't need to say anything more, Envy. ''The first thing I'm gonna turn to ash is your tongue''.]]"
*** He makes damn good on this promise, [[spoiler:He then proceeds to alternate between full, body-consuming explosions, and pinpoint attacks that target the most sensitive and painful areas, notably the eyes. Repeatedly. OUCH!]]
** Notably averted, however, with the Homunculus Wrath. Despite being a ruthless fighter, he is always calm and composed in a fight.
** [[BigBad Father]] as well [[spoiler:in the Final Battle he shows much anger]]
** Ed invokes this in his initial battle with Ling Yao's bodyguard Lan Fan. The twist is that he drives Lan Fan into an Unstoppable Rage by insulting Ling, causing her attacks to become wild and reckless, and therefore much easier to dodge and counter.
* In the first part of "Jupiter Jazz" from ''Anime/CowboyBebop'', a gang leader made the mistake of [[BerserkButton calling Spike Spiegel by the name of his rival, Vicious]]. Spike went berserk and handed a supreme asskicking to the entire gang before laying into him.
-->'''Spike:''' You think I'm Vicious? YOU DON'T KNOW WHAT VICIOUS IS!
* It's never wise to threaten/try to kill [[ActionSurvivor Yukiteru]] in front of [[{{Yandere}} Yuno]] in ''Manga/MiraiNikki''; this chick put the yan (sick) in {{Yandere}}.
* One: Do not mess with [[TheQuietOne Senri's]] friends. Two: Do not remove Senri's eyepatch. Three: When white hair appears on his forehead (after you have ignored number two), you run away as quickly as possible, through that really isn't going to help, you're going to be clawed to bits anyway. Even if ''Manga/PlusAnima'' is a children's manga, it doesn't skimp on the violence when necessary.
** You get to see Senri [[spoiler:go into an Unstoppable Rage two times. Once while he is a young child, and the other time he's in Moss Mountain with Cooro, Nana, and Husky.]]
* In the final episode of ''Manga/DeathNote'', [[spoiler:when Light Yagami is exposed as Kira, Touta Matsuda [[TwistedKneeCollapse slumps to the floor]] [[HeroicBSOD under the weight of it all]], but springs into action faster than anyone else when Light attempts to escape by murdering everyone with the Death Note piece in his watch. Matsuda then shoots him in the hand, with ManlyTears coming down as [[WhatTheHellHero he calls Light out]] on leading his father (and Matsuda's ObiWan) to slaughter for nothing. When Light tries to convince Matsuda that the only way to make Soichiro's justice worth it is to save Light and kill the SPK and investigation team, he's only ''more enraged'', and snaps when Light once again tries to write names in the note fragment with his own blood. '''He shoots him multiple times''', and tries to finish him off with a shot to the head, but is held back by the other members of the investigation team. Coupled with the fact that he was the only member of the team to have any doubts about whether Kira really was evil, Matsuda's CrouchingMoronHiddenBadass moment is even more impressive.]]
-->'''[[spoiler: Matsuda]]:''' ''"I have to kill him! HE HAS TO DIE!"''
* ''Manga/KatekyoHitmanReborn'': Averted when the berserk rage is only powerful for five minutes and it is in itself not unbeatable. Tsuna is at his best when he is on the other side, straight past normal, straight past calm, all the way onto the other side where he is completely empty of feeling and is thus at his most level of head. Results in loads of arse kicking. But... there comes the time when he just has to lose it for a moment, and that's when [[spoiler: he kinda hit Byakuran with an X-burner so hard that Byakuran vaporized. Scary...]]
* The otherwise peaceful and docile Ohmu of ''Manga/NausicaaOfTheValleyOfTheWind'' fly into an Unstoppable Rage if the Sea of Decay or any of its insects are harmed, killing and destroying everything in their path in an attempt to claim vengeance against whatever is responsible. In the manga, we're privy to their thoughts through Nausicaa's empathic link with them, and they seem to regret their actions once they regain their senses.
** Nausicaa herself flies into a rage and [[spoiler:annihilates a roomful of trained soldiers with just a staff]].
* England of ''Manga/AxisPowersHetalia'' flies into one of these during the [[UsefulNotes/TheAmericanRevolution War of American Independence]]. Despite America's formidable SuperStrength and the fact that England [[OneManArmy doesn't seem to have any backup]], he still manages to disarm America and level a musket point-blank at his face.
* The Nodos in ''Anime/HeroicAge'' are NighInvulnerable {{Kaiju}} possessed of [[PersonOfMassDestruction incredible destructive power]] to begin with, but under certain circumstances (such as when more than two at a time are engaged in a fight) they can go into "frenzy" (or "madness" or "mental chaos", [[LostInTranslation depending on the translation]]), becoming even ''more'' monstrous and destructive. The Heroic Tribe apparently destroyed several entire ''star systems'' through such rages during their civil war, hence why the Golden Tribe sealed the survivors within members of other tribes, making them slaves to these "lesser" beings.
* Ivan Isaac's superpower in ''Manhwa/{{Priest}}'' is his sheer rage and contempt for Temozarela. He doesn't even ''care'' whether or not he wins against him, he just wants Temozarela to see how ''angry'' he is.
* Shizuo Heiwajima in ''LightNovel/{{Durarara}}''. He actually doesn't like violence, but set him off -- and [[HairTriggerTemper many things set him off]] -- and he can't stop himself from [[SuperStrength throwing something unreasonably heavy]] at you.
* In episode 11 of the ''Anime/TenchiMuyo'' SpinOff ''Anime/TenchiMuyoWarOnGeminar'', the antagonists' latest and dirtiest attempt to kill Kenshi pisses him off so much that he goes utterly apeshit. His [[HumongousMecha Seikijin]] partially transforms into a horrible black giant ''thing'' that mercilessly beats down his opponents [[spoiler:and actually ''kills'' one of them [[KarmicDeath (the one that came up with the scheme in the first place)]]]]. It's so terrifying that [[spoiler:Dagmyer]] has a FreakOut that segues into a two-episode-long VillainousBSOD. This is a {{subver|tedTrope}}sion -- Kenshi's rage overloads the Seikijin even faster than normal and [[HeroicRROD causes it to fall apart midway through the battle]]. This is the only reason [[spoiler: Emera was able to rescue Dagmyer]].
* In ''[[Anime/{{Bakugan}} Bakugan Battle Brawlers]]'', ''never'' let [[TheDitz Ditzy]] HybridMonster Rabeeder overhear that her sister is defeated or possibly dead. The ditz who hit on the main character and challenged you to silly races before might only give you a single [[DeathGlare death's glare]] warning before beating the ever loving tar out of TheDragon, ''that'' dragon's Dragon, and [[KickTheDog their little dog, too!]]
* ''Manga/HajimeNoIppo'': Don't make Takeshi Sendo angry while in the ring. You'll live longer. Shigeta and Ippo both have been victims of his flip-outs. It's not a nice situation to be in, really.
** In his fight against Bryan Hawk, Takamura goes into a state of pure, uncontrolled rage (while half-unconscious to boot) and proceeds to beat the flying shit out of Hawk.
* Subverted in ''Manga/SoulEater''. After spending 800 years waiting, [[spoiler: having his boss/partner killed, and going so far in his revenge plot as to grow a second, back-up body,]] [[ChainsawGood Giriko]] is all sorts of insane with rage. His limitless fury gives him such a power boost that Maka and Soul are quickly on the ropes. Unfortunately, he's built up so much rage that [[spoiler: he overloads his soul. He rages so hard his soul explodes and he dies.]]
* ''Manga/SorcererHunters'' protagonist Carrot Glace suffers a unique combination of conditions. His body naturally absorbs any spell that hits him, and the energy from that spell transforms him into some nigh-unstoppable beast. The only two people who seem consistently able to snap him out of it are his coworkers and the two girls he normally avoids whenever he can: the Misu sisters, Chocolate and Tira.
* After spending almost the entire second season as nothing but a hostage, Kojuro of ''VideoGame/SengokuBasara'' escapes, and finds out that Hanbe, the jerk who had constantly tried to convince him that Masamune was dead, gave his lord a scar across his back. He is less than pleased about this. He promptly rides off, ''without a sword'' , finds Hanbe's unit, and proceeds to beat all of the mooks ''bare handed''. He then steals a sword, and goes berserk on Hanbe himself.
** This is Mitsunari's raison d'etre following Hideyoshi's death. Whoever may be on the receiving end of his anger, nothing is gonna get in his way until he hunts them down and chops them into mush.
* In an episode of ''Anime/HaloLegends'', Harka has the wife of Fal 'Chavamee, the original Arbiter, killed to provoke him into a duel after he refuses to serve the Covenant. [[spoiler: Fal wipes out an elite hit-squad, hundreds of Covenant infantry, a Wraith and three gigantic Hunters before dying along with Harka in the eponymous duel.]]
* ''VideoGame/GalaxyFrauleinYuna'': If you kill one of Yuna's friends, she won't care how much of a Badass VillainSue you are. ''[[BewareTheNiceOnes She]]'' ''[[ThisIsUnforgivable will]]'' ''[[IllKillYou tear]]'' ''{{you|Monster}}'' ''[[ThisMeansWar to]]'' ''[[YouAreAlreadyDead shreds]]''.
* In the second series of ''Anime/{{Beyblade}}'', Kai has a major guilt-induced HeroicBSOD while fighting Goki, because Goki's MindControlEyes reminds him of Wyatt, who is dead/insane depending on the version and it was Kai's fault. ("I can't fight you. Not you.") He snaps out of it on his own, but still isn't strong enough to take down uber!Cyber Dranzer. Then Goki refers to Wyatt as "your wimpy little friend" and, well. Dranzer hits BattleAura and the title trope ensues.
* Don't mess with any ''Manga/FairyTail'' members.
* In ''Manga/{{Trigun}}'', Vash is normally a pacifist who refuses to kill anyone, trying his very best to non-lethally shoot at people (unrealistic, but for the context of the story one just has to roll with it) which puts him in bad situations with the major villains of the series who don't go down as easily as a normal person would from his non-lethal shots. On one notable occasion, the villain was unaffected by Vash's attempts to non-lethally defeat him but when he murdered a lot of people right in front of Vash's eyes Vash pulls out his machine gun arm and quickly immobilizes the villain. In his weakened state, Vash knows the villain can't fight back but in his rage he seriously considers killing him. However, he holds true to his morals and lets him go. This shows you that Vash would be an unstoppable gunfighter if he went in for the kill from the start.
* In the ''Anime/MegamanNTWarrior'' manga, Megaman's SuperMode starts out as this until he learns to control it. Another example comes a few chapters later when Shademan threatens Lan. Megaman ''rips him apart''.
* In ''Manga/VinlandSaga'' Canute has a divine revelation that transforms him from a frightened sissy into an incredibly charismatic and powerful leader. And the very first thing he does is to calm down a raging berserker four times the size, that is about to crush him, with a CooldownHug. After that, he only has to look at people to make them worship him.
* In ''Manga/BlueExorcist'', Rin has some... problems with restraint once he draws his sword to transform into his demonic form. This was especially visible in his fight against Amaimon in the anime as he started off as a bit angrier version of himself but ended up as a snarling and growling bundle of AxCrazy, behaving more like a feral dog than a human. Right in front of his TrueCompanions who up until that point thought he was a BadassNormal and [[SuperweaponSurprise definitely not the son of]] ''{{Satan}} himself''. Good thing Shiemi was on-hand for a CooldownHug, otherwise it would've gotten real ugly real quick.
* ''VisualNovel/HigurashiNoNakuKoroNi'': Somewhat of a subversion in that those who perform these are usually quite unstable and sometimes presented more [[VillainProtagonist darkly]] than a standard hero, but standard procedure in most arcs nonetheless. Basically, if you harm [[TheChewToy Satoko]], or don't believe in Oyashiro-sama, or if a certain Yandere thinks you're connected to [[spoiler:her boyfriend's disappearance]], you're bound to be on the receiving end of one eventually. Doesn't help that [[spoiler:the local HatePlague that makes people prone to dish this out in the first place seems to give them enhanced strength and senses.]]
* ''Manga/FruitsBasket'': [[SuperpoweredEvilSide Black]] [[SplitPersonality Haru]] is essentially Unstoppable Rage ''incarnate''. Most of the time he's content to just taunt or beat up whatever poor soul rouses his ire, but when he discovers that [[spoiler:Akito threw Rin out a second-story window]], [[OOCIsSeriousBusiness he goes into a]] TranquilFury until he reaches the Sohma estate, then tries to ''kill'' Akito. It takes all of Akito's considerable [[BreakingSpeech powers of persuasion]] to stop him.
* Eren Yeager, the protagonist of ''Manga/AttackOnTitan'', runs on this when [[spoiler:he's in Titan form]]. It's absolutely terrifying, even to battle-hardened soldiers and [[spoiler:fellow Titan Shifters]].
