Berserk Button / Fan Works

Go To

When a nice, normal character suddenly goes into a rage, you've hit their Berserk Button.

Avatar: The Last Airbender
  • Bring Me All Your Elderly! has many:
    • Toph loses it at the "Pebble Dance", deciding to break off from the main fic and beat some sense into the Earthbenders.
    • Narrating is one for Katara (particularly when Katarola is doing it). She also hates the scene in the Earthbender prison because of 1) the fact that Awng gets her inspiring speech and 2) the sheer stupidity of the scene in general.
      • She also flips out when Katarola attempts to make out with Aang, understandably.
      • Most things Katarola does are a berserk button for Katara, actually.
    • Advertisement:
    • Zuko has a brief mental breakdown when he discovers that he is actually a cartoon character.
    • Lord Shyamalan goes berserk when Awng, of all people, starts criticizing some of the movie's flaws.
    • Sockson loses it at one point when Sokka abruptly chops off his ponytail. Unfortunately for Sockson, Sokka is a much better fighter than he is.
    • Sockson's failed attempt to hit on Katara works as a berserk button for Katara, Aang and Sokka simultaneously.
  • In How I Became Yours, Zuko has two that Mai pushes- insulting Katara and calling him a "chard monster".
  • Kyoshi Rising: Kyoshi is not fond of imposters pretending to be the Avatar.

Batman Beyond

  • Batman Beyond Revisited:
    • Jake does not like being seen as inferior to Bruce.
    • Dick does not like anyone insulting Bruce.



Buffy the Vampire Slayer

  • The One With The Angelic Face:
    • Angela uses Spike’s old insecurities about how he compared to Angelus to try and provoke him into killing her before he can heal Drusilla; Buffy later suggests that Angela found it a lot easier to abuse Spike in the past compared to the effort he went to just to tie her down here (while unaware that Angela was a man at that point).
    • Any threat to Angela’s life tends to do this for Buffy, particularly after she’s separated from Angelus (even if the threat comes from Angela herself).

Calvin and Hobbes


  • In An End to All Things, messing with Kotomi appears to be one for Okazaki, as evidenced by his reaction when Kotomi's godfather shows up.

Code Geass

  • In Code Geass: Redo of the Rebellion, Suzaku is C.C.'s button because of Lelouch's death. She declares that she doesn't hate Suzaku for killing Lelouch, she hates him for helping drive Lelouch to that point and not protesting Lelouch's plan to have himself assassinated.
  • Advertisement:
  • In The Black Emperor, Lelouch is quick to get angry if somebody accuses him of being motivated by mere ambition. He emphasizes that he's not just out to take the throne of Britannia.


  • A Heros Wrath:
    • While it isn't hard to piss Asura off, he won't actually try to hurt you unless you do something especially despicable. Usually this translates to familial abuse, having hunted down and nearly crippled Endeavor when he found out what he did to his wife and eldest son.
    • While short-tempered, do not mock any of the Midorya Family around Izuku. He threatened to cripple the last guy who claimed his sister was guilty of something.
  • Don't remind Firefly from Ace Combat: The Equestrian War about the death of her parents.
  • A Shadow of the Titans: Don't come between Gadjo and his pies. For a good example of why, it's shown that a previous employer of his once tried to summon an Eldritch Abomination; when Gadjo realized that The End of the World as We Know It would mean no more bakers and therefore no more pies, he proceeded to rip his boss' head off with his bare hands.
  • In A Triangle in the Stars, Bill Cipher alone has had so many that if it was an Oscar, he'd win it ten times over. And he's already pretty angry. Here's the most prominent ones:
    • Do NOT, and I repeat, do NOT take his hat and/or take selfies with it if you want to see the light of another day.
    • People backing out of deals, as carried over from his home series, still gets him angry. Especially when they're trapping deals.
    • Betrayal, or moreso perhaps wasting time, is also a big one, and Keyhole learned it the hard way.
    • Touching him is a minor one. He won't outright blow up, for reasons, but he'll be miffed. Except for the first time, which was a hug. This goes away by Chapter Twenty-Nine.
  • In Avenger of Steel, the idea of being under someone's control (albeit only through a control collar rather than actual mind control) sends Jessica Jones flying into a rage where she beats a woman into unconsciousness when the woman had just been beating Jessica down only a few moments ago. Later on, the knowledge that Clark is about to face a woman who can control men prompts Jessica to break her ‘rule’ about staying out of super-heroics to join Clark, Sif, Natasha, and Coulson’s SHIELD team in confronting Lorelei.
  • Don't ever insult background character Ditzy Doo's child in Better Living Through Science and Ponies and expect to get away with it; she doesn't mind the mocking nickname 'Derpy Hooves' but dissing her foal will just lead to her helping Chell wreck you.
  • In the Pokémon/Yu-Gi-Oh! crossover Between My Brother And Me Mors Omnibus there are a lot of people who will go apeshit on you if you push their buttons.
    • Yvonne Maxa is a snarky puppeteer who doesn't mind if you happen to call her a "Puppet Bitch", but if you hurt her adorable puppets or if you're from Academia who boast about carding people, then she will use her knives and kill you on the spot.
    • Max Lang is an adorable little vampire boy who loves cartoons. Insulting them — as Edo Phoenix did — makes him drop the energy and calmly ask you, "You gotta problem with cartoons?" and proceed to kick your ass in a duel.
    • Dawn Fujiki does not like anything that is a reminder of the Lost Incident (justified as it massively ruined her older brother's life).
    • Seto Kaiba treasures a precious scarf that he wears all the time (it's from his mother and is used to hide that his neck was slightly snapped after he was hanged, It's a Long Story) and touching it is enough for him to snap. Better yet, harming his mother is enough for him to down right kill you.
    • Ash Ketchum is usually calm and will give cryptic comments on one's future through his Aura powers. Insulting his skill with aura is enough for him to cry "BLASPHEMY!"
    • If there's anything the Dark Signers hate (specifically Yusei, Kiryu, Misty and Carly) it's abuse on children. This is one of the sole reasons why they give Himika Akaba a Break the Haughty procedure due to her abuse on Reira.
    • Yuya Sakaki (after he was brainwashed by Zarc) hates Yusho — his true father — for abandoning him all those years ago.
  • In most crossover stories involving him, Ranma hates when someone implies he became as strong as he is through anything but hard work. Big Human on Campus and Anything Goes Game Changer both make it a plot point that Ranma views it as an outright insult to his skill to suggest he's a monster or sekirei respectively.
  • In Biology Say What?, don't ever insult Xander Harris where Safira can hear, not even if you're a fellow Slayer.
    Jolie: He barely graduated from high school, never went to college, and can't do any magic. He only went to Africa because no one else wanted him.
    Safira: Jolie, you will never talk about Xander that way again. If you do not get your ass out of this elevator and into the apartment I will forget that I am almost three feet taller than you and out weigh you by a hundred pounds and I will beat your ass into the ground.
  • Child of the Storm has a fair number of examples, thanks to its density, having Loads and Loads of Characters, and said characters having darker sides.
    • Harry is initially fairly relaxed, but after slowly becoming a Shell-Shocked Veteran, a few useful rules of thumb start to apply: don't be a bully, or your punishment will be... creative. Don't ask him to abuse his Psychic Powers, or do so anywhere near him - after one experience on the wrong end of Mind Rape, he's willing to kill.
    • Doctor Strange, by far the most dangerous character in the story, has two: don't condescend to him and don't suggesting that he might break his word (he has a self-imposed case of Cannot Tell a Lie). They respectively result in a savage "Reason You Suck" Speech to a group of Physical Gods and the threat of an And I Must Scream fate for the one condescending to him ( Zeus), and a more or less explicit statement that if the person questioning his word had not been a child themselves, he'd have killed them on the spot.
  • Children of an Elder God: Asuka was not enthused about touching —let alone fighting— Amaliel. Then the acuatic cosmic horror bit her robot's hand off. Asuka bludgeoned it, torn its limbs off and then ripped flesh chunks off its body until she was sure it was very, very dead.
  • Coreline: For recurring character Roger Hackett, it is insulting Mega-Corp Stingray Industries and especially the Corporate-Sponsored Superhero team it sponsors, "The Champions". Don't even think about it, in any way, shape or form. Not even if the universe decided you're in the right. Because it won't matter if you're a super-duper-ultra-mega-hyper Physical God Supersoldier Stock Shōnen Hero with an army of followers or just a regular Jerkass — if he likes you, or thinks you are indispensable, he'll feel torn and guilty about his desire to make you pay, and if he doesn't... then Heaven help you.
  • The Dragon That Will Pierce the Heavens: It is not a good idea to threaten innocent people or the Straw Hats in front of Hikari, especially Luffy, Zoro or Chopper. This usually causes her to have a Roaring Rampage of Revenge against the person responsible, transforming into a Draconic Humanoid One-Man Army capable of taking down entire crews of pirates.
  • Dungeon Keeper Ami:
    • Marda:
      • Having her trolls comment on her attractiveness. She will give them a proper beating if she catches that kind of talk. This is because he was originally male, and was implied to have been raped after being captured and transformed into a female troll.
      • Arch-Enemy: Mukrezar.
    • Boris:
      • Keepers in general, due to what he experienced thanks to Mukrezar destroying his hometown. When he finds out Ami is a Keeper, he's perpetually either on the edge of exploding, or actually trying to kill her.
  • Fates Collide:
    • Atalanta does not like wasting food. She gets very angry when Ruby Rose trips and spills a tray of food all over Mordred.
    • Yang Xiao Long throws Mordred's cigarettes in the trash, leading to her chasing Yang around the school.
    • Cu Chulainn gets upset when he finds out Archer has a copy of Gae Bolg inside Unlimited Blade Works, because it is left lying in a pile of other weapons instead of neatly stacked. Archer counters since his arsenal is unlimited, it's impossible to organize.
    • Nero Claudius gets pissed when she finds out Ruby creates rose petals, as that is one of her own abilities that she thought was unique. She gets even more pissed when she finds out Ruby's last name is Rose.
    • Mercury Black gets pissed when Kirei Kotomine asks him about his father, whom he hated.
    • Penthesilea hates Achilles, and she also hates girls he spends time with like Atalanta and Blake Belladonna.
    • Like in canon, Yang's is messing with her hair.
    • Cinder Fall does not like people who were born with powers, as she believes they didn't earn them. She also gets angry when people ask how old she is or imply that she is old.
    • Frankenstein does not like anyone talking about her original father who abandoned her.
  • Fate/Stay Night: Ultimate Master: Just like in the canon, trying to endanger innocents or civilians on front of Ben is a bad idea. When Archer tries to use this against him, he goes berserk and basically throws Archer out the battlefield. Later, when Illya tries to send Berserker to kill Shirou, Ben turns into Way Big and squashes Berserker.
  • Kugimiya in Happy Families Are All Alike (Naruto/Negima crossover) gets pissed when her friends suggest that she's masculine.
  • Here be Dragons:
    • Don't let yourself get caught trying to tamper with Atreus's mind. The very least you can expect in return is a harsh chewing-out, and that's if you're lucky. Far more likely the Force will be used to retaliate.
    • Smuggling is one thing, as long as you don't get caught, and be repentant if you do get caught. Disobeying a direct order to his face, though? Big no-no.
    • He also really, really hates traitors. How much? The second time he caught one, he nearly went Dark Side with anger and tried to Force Choke the culprit to death.
  • Gentaro in Horseshoes and Hand Grenades gets pissed if anyone starts bringing up the term of 'friendship', Ryusei Sakuta/Kamen Rider Meteor, or the word "Stop!". The last one is important because it was the last thing he heard before Meteor gave him the one-inch punch, and also because it was said by his dearest friend Yuki who said that, but never went to his aid.
    • In the side stories Wheel of Fortune and Month of Sundays, Mei Shirakawa gets mad when someone says the words "Rental service", and Damballa does not like it when he is stated to be similar to a Zodiarts and gets pissed upon seeing Aries the most because Aries Zodiarts killed off his son and daughter-in-law and his grandson was also lost in the struggle.
  • Infinity Train: Blossoming Trail: The main one for the Red Lotus Trio is that hurting one another will have the other two retaliate in quick succession, but they individually have their own personal buttons;
    • Chloe personally has a dislike for curry and Pokémon, due to the years of emotional baggage attached with those things, and being called a princess as it makes her look weak and pathetic.
    • Atticus is attached to his little crown and taking it is just asking for the King of Corginia to chase you down.
    • Lexi, due to spending the past few years of his life consciously buried alive thanks to Grace and Simon, he absolutely detests most passengers (or "free-riders", as he calls them) as a result. Especially the two who did it to him.
  • Interventions:
    • Peter muses that Caleb killing so many young women just for the sake of it has bypassed Peter’s usual ‘live and let live’ attitude and deserves to die.
    • Maury Parkman’s actions against Molly prompt Matt and Willow to terrify him even before Matt causes him to have a fatal heart attack.
    • After Doyle the puppeteer captures Dawn, the only reason Connor doesn’t kill Doyle is that he recognises that Dawn needs him, and he leaves Doyle for Spike to finish off anyway; Spike later asks Buffy if she seriously didn’t expect Spike to kill someone who had threatened to hurt Dawn like that.
    • Willow basically pushes all of Sylar's as she prepares to condemn him to a Fate Worse than Death.
  • In The Lone Traveler, the Traveler hates people being given no choice—whether explicitly or not—or being forced to make a decision when the information they have access to has been deliberately restricted. This becomes such a defining trait of his character that he is eventually made God of Free Will.
  • Lost to Dust: Minamoto no Raikou gets very angry when someone calls having a child a mistake. To her, children are miracles and they are never a mistake.
  • The Many Dates of Danny Fenton:
    • It doesn't matter if he is out on a date with you or not, Danny will not tolerate anyone hurting innocent people, especially kids. Cree and Vicky learn this the hard way.
    • A lesser one is that Danny won't accept being disrespected on his blind date and will be quick to tell the person who did it off.
  • Metroid: Kamen Rider Generations: Mitsuzane has few. One, do not remind him or bring up about the misdeeds he committed in the past. Two, don't touch him; Samus is the only ones who can do that. Gandrayda learned the hard way. Three, threaten his friends and his brother is the easiest way to piss him off. And fourth, you don't make fun or insult Kouta on his ears. You'll regret it, Gou almost found out the hard way when he had to refer Kouta as Jesus Yamato.
    • Gou has two: (1) Insulting Chase in front of Gou will ask him to kick your ass. (2) Never, EVER mention the name Tenjuro Banno when Gou is around, unless if you're Krim.
  • In Monsters In Paradise, Chen has no problem calling a Delcatty she didn't even own "Creampuff". However, calling her that same name is enough to enrage her into declaring an attack against the perpetrator. Not that it helped against Blastoise...
  • Paper Mario X: Kirby when he hears Meta Knight kissed his girlfriend, Bow.
    • Don't make fun of Samus in front of her. Sonic and Link found that out the hard way.
  • In the Megamind and Rise of the Guardians crossover fic Protectors, Roxanne's elder sister, Rikki, doesn't like it when adults threaten/use/discriminate young kids. To the extent that she punches her own mother when said mother makes an unwise move towards Roxanne.
  • Rise of the Galeforces: Whatever you do, do NOT call Adam a "dinosaur." Played for Laughs twice... and very much Played for Drama alongside another Berserk Button - harming Violet in front of him - in Chapter 25, leading to an Unstoppable Rage.
    • And while we're at it, it's probably not a good idea to call Dash a "morsel" either. Velociripper does exactly that in Chapter 6, and gets toasted.
    • If you fuck up the canon Violet is participating in, threaten her family, or yank her chain on a personal level, she will END you. Ludlow learned all of these the hard way, and did not live to tell the tale.
  • RWBY: Epic of Remnant: Lancelot does not like his former king being brought up. Even saying "Arthur" in a casual conversation is enough to send him into a rage.
  • Say It Thrice: Betelgeuse does not take kindly to anybody messing with his girl, or keeping him away from her. Lydia is his Protectorate and Morality Chain, and her well-being is his highest priority. On the flip side, Lydia doesn't really like it when anybody messes with ghosts in general, and him in particular; befriending Danny Phantom and his pals only makes her feel this more strongly.
  • In The Search for Victory, just hearing about what the Goa’uld did to Cassie when she was just a child nearly causes Bruce to transform into the Hulk.
  • Sonic Generations: Friendship Is Timeless : Do not make Amy angry. Spike found that out the hard way.
  • In Shadow Crystal Mage's Lyrical Nanoha/Green Lantern Mega Crossover fic Takamachi Nanoha of 2814, the fact that Pluto is no longer a planet really sets off Sailor Pluto, causing her to go into a Berserker Rage. It's very effective when the Wolkenritter show up...
  • In SariSpy56's Tales from Mellowbrook, a Kick Buttowski: Suburban Daredevil crossover fanfic, a few characters and fan characters have berserk buttons: Avery Buttowski, a cousin of Kick Buttowski (on his mother's side) had a few berserk buttons: In the tale A Visit From Avery 1) it is not wise to call Avery a Mexican. Your ass will turn red if you do so. 2) She hates not only Lois, but everyone in Quahog due to their cruel nature. Except Meg of course. 3) Don't harm either Kick or any other members of her family in front of Avery. An evil babysitter from "The SpyNapping Sitter" learned that the hard way. 4) Don't compare her to Father, the archenemy of Kids Next Door. She hates him for making her grandmother's life a living hell. 5) Don't harm Johnny Test in front of Avery. She doesn't even care if it's about 98% the population of Mellowbrook. DON'T FUCK WITH AVERY! 6) Avery is not annoyed by people, unless you're either Quagmire or Wacky Jackie. Quagmire did that numerous times whenever Avery mentions his name. Jackie only did that whenever Kick is present with Avery. 7) Annabelle Magnuson, Gunther's cousin also had a few berserk buttons (her character is still in progress) 9) Whenever Annabelle is going on a trip and the only route is the airplane, if you value your life, DON'T ask her to change seats for ridiculous reasons. Dash Baxer learned that the hard way. 10) Brad doesn't like it when other males (Gordon Gibbles for example)flirt with his beloved Selena. Do so and Brad will pound you into turkey meat.
    • Kick had a few berserk buttons in a few tales: 1) Don't harm Kendall when Kick is present. Start praying for your life. 2) Like Avery, Kick hates everyone in Quahog (except Meg). 3) Don't harm his family or friends when Kick is present. Better start praying for you life. 4) Whenever Kick is the subsitute barber, don't annoy him or give him ridiculous commands if you value your life. Once his button is pressed, he will go insane like Sweeny Todd. Peter Griffin learned that the hard way.
    • Kendall had only a few to begin with: 1) Kendall would normally be uninterested into doing awesome things as suggested by either her friends or anyone else. But mention KitKat candy bars and she'll be interested. 2) She hates being called "Kandy". This happens only on Avery as in the past, she and Kendall used to be bitter rivals.
  • Thousand Shinji:
    • Asuka has several buttons. Calling her useless or a doll is downright suicidal. But if you hurt Shinji or try to seduce him, pray for a quick death.
    • Shinji is usually controlled. However, if you make a fool of him, he gets furious. If you hurt his family he gets homicidal.
  • The Three Kings: Hunt: Ryou might be an overall nice guy but do not threaten his sister because he will hurt you if you do.
  • Time Lords and Terror: Over the course of the story the Doctor manages to hit a couple of Twilight Sparkle's buttons, like accidentally teleporting one of her books to the sun.
  • Turnabout Storm:
    • Do NOT ask Rarity about why she didn't show up at the trial, NOR mention the post office or pens in her proximity. Phoenix learnt it the hard way.
    • For a more subdued but serious one, do not talk bad about your siblings around Cruise Control.
    • Do not call Gilda slow, she's already ballistic enough as it is without the entire courtroom telling her that.
  • In The Wizard in the Shadows, if you hurt someone Harry cares about, he will burn you until there is nothing left, hit you with lightning bolts that vaporised a Mûmak (and that was a secondary effect), or use the Cruciatus curse in fairness, he had just found Sirius who Saruman had been torturing for the last seven years on you repeatedly.
    • Ginny has the Violently Protective Girlfriend thing going on with Harry (not that he can't fight for himself). When he dies temporarily, she destroys most of Mordor's army (by channelling some sort of higher power), utterly destroying the physical forms of three of the Nazgul.
  • The Equestrian Wind Mage:
    • Also, don't ever let Vaati catch you bullying someone. EVER.
    • Don't kidnap Rarity. Maulgrim will not be pleased.
      • Plus, don't call Maulgrim a chicken. He will make you regret it.
  • Dante is shown to be extremely protective of his daughter Evie in Dante's Night at Freddy's 2: Animatronic Boogaloo, to the point of completely losing his iconic cool when she is threatened.
  • Wonderful!: If you steal L33t's tinker technology and, to add insult to injury, make it work, he goes very, very mad.


  • Despair's Last Resort has a few:
    • Ayame can't stand being told that she's not feminine enough. People would tell her this constantly because she enjoyed playing football/soccer.
    • Kumiko hates being called an otaku. She may visit Akihabara, collect manga, and play video games, but she wants no association with the otaku name. She also gets mad after Ryouta slanders Shizuka's name, and punches him in the face for it.
    • The usually stoic Miyako gets irritated after everyone starts fighting with each other over petty things. She actually chews them out for acting like idiots.
    • Shuuya gets furious when Saemi starts badmouthing the late Miyako, going so far as threatening to kill her right there.


  • Can't Get You Out Of My Head has Joker, who takes a very, very dim view of implicating him in something that he didn't do. as he put it:
    "There isn't enough room in this town for me and somebody who would do a thing like that, and they're going to be the ones to go. I am going to find whoever did this, expose them, and clear my name. And then I'm going to teach them the error of their ways. Over several days. With a dull knife dipped in iodine, so it really hurts and so they don't get an infection and die before I want them to."
  • DC Nation:
  • From The Doctors and the Nurses They Adore Me So, hurting the Joker's dog is bad for everyone.
  • Stephanie Brown/Spoiler puts up with a lot of crap in Angel of the Bat, but mocking the events of War Games (in which she was raped, tortured and forced to fake her death) is a surefire way to get your face broken. Just ask Scarab.
  • Our Own League series:
    • Kara has an intense hatred for any form of captivity, due to being trapped in Brainiac's city collection for thirty years.
    • In Teen Titans: Together for Tomorrow, upbeat-verging-on-Stepford Smiler Conner gets so angry at Damian for resorting to using an obedience-inducing Trigger Phrase on him, he blasts eye lasers close enough to singe the tips of Damian's hair.
    • Arsenal, a Recovered Addict, is prone to flipping out at the mere mention of drugs. Especially so if it's said around his daughter Lian, the reason he got sober in the first place.
    • Lian is a pretty violent person in general, but either insinuating that archery is lame or that the "Arrowfam" are B-list heroes will send her into a specific rage.

Death Note

Devil May Cry

  • In the AU fic Like Father Like Son, while it takes several chapters for Dante to confirm that Nero is his son, once he does confirm it, messing with the kid is a very good way to bring down Dante's full Papa Wolf wrath on your head.


  • In the Discworld of A.A. Pessimal, it is not wise to display any racial prejudice in front of proud Howondalandian graduates of the Guild of Assassins. Miss Ruth N'Kweze is normally pleasant, easy-going and possessed of a pleasantly barbed sense of humour. But for a while she was a teacher at the Assassins' Guild School, and an White Howondalandian student who used the word "kaffir" where she could hear it soon realised his teacher was annoyed, and prepared to do more than throw the blackboard eraser at him. Horst Lensen still carries a slight scar on his throat where her sword was pressed against his vocal chords, just to make the point.note  Similarly, any anti-Cenotian slurs expressed where Miss Rivka ben-Divorah can hear them are usually met with telling retribution.

Doctor Who

  • In Time and Space by Eureka2000, Epsilon's sore spot is the Time War and implying that she was anything like Rassilon and his followers.
    • And don't ever do anything stupid in front of Zanna Sterling. Just ask her brother.

Dragon Age

  • In the Skyhold Academy Yearbook series, the teachers at the eponymous school will get angry very quickly if anything endangers the school itself, or the other staff members, or worst of all the students. Varric has an extra one; don't even imply that you're a danger to either of "his girls" (the Hawke sisters), because he will end you. Literally.


  • in this story series, Roy Desoto gets VERY angry if his partner John Gage gets hurt. It sometimes extends to Roy's wife, the other guys of Station 51, and Dr. Brackett and Dixie. All are very fond of John and want to keep him safe.

Ever After High

  • In Poisoning Apple, do not make fun of Apple's singing or say that she's a terrible singer.
    • Don't mess with Rotbart's pet owl or force cute stuff on him and for all that is holy, don't mess with his sister, Raven.

Fate/stay night

  • Fate/Harem Antics:
    • Caster is Medea, who was abandoned by her husband Jason for another woman. So she's not particularly fond of any mention of cheating or stealing someone's significant other. She's normally shy and reserved, but when Luvia suggests stealing Shirou from Rin, Caster immediately gets angry. She grudgingly accepts Luvia just flirting with Shirou to piss Rin off.
    • Temptress (Elizabeth Bathory) hates anything that even remotely implies that her voice is not beautiful or that people don't want to hear her sing. When Assassin politely asks her to please keep her voice down because they are in a sleeping neighborhood, Temptress goes berserk and says she will pay with her life for that "insult" before trying to kill her.

Final Fantasy VII

  • Us and Them:
    • Don't spell Aeris' name wrong, she really doesn't like it.
    • Due to a mishap that causes her to skip ahead in time ten years, Ifalna finds herself becoming a grandmother while still in her thirties. She doesn't like being called "Grandma" at all. (She eventually comes around to it.)
    • Do not bring up the JENOVA Project around Sephiroth.

Friday the 13th

  • In Scream For Me, calling Jason a retard and/or insulting his mother, telling Freddy he lost in Freddy vs. Jason, messing with Michael's shampoo, or taking Ghostface's drugs away from him, are all definite ways to get attacked/killed. Series can be found here.


  • In What About Witch Queen?, threatening Anna - or even suggesting threatening her - is a sure way to attract Kristoff's ire, and boy, fear his wrath. Also, any news about Hans are bound to make Friedrich go full berserk and the same - although to lesser extent - applies to Anna as well.

Fullmetal Alchemist

  • The Fullmetal Alchemist fanfic series The Elemental Chess Trilogy has all the same berserk buttons as the original canon. In addition, though, some others come up. Don't mistreat women in the vicinity of Alex Louis Armstrong (or, as shown in a flashback, Roy Mustang). Don't mess with the members of Team Mustang if you don't want to feel the wrath of the rest of the team. And pray for deliverance if you're caught red-handed having something to do with the disappearance and possible murder of Riza Mustang, because if her husband doesn't incinerate you (and that's a really big if), their friends will.
  • In Son of the Desert, don't make racist comments about Ishval in front of Ed or Al.
  • In i'm giving you a nightcall, don’t threaten Ed, even if you are Ed. Edward as Fullmetal tries to give Roy information and flirt with him to put him off his game. But then Fullmetal says something sounds like he’s threatening Edward which causes Roy to go ballistic.
  • Aside from his usual feelings about his height, Edward in My Master Ed hates it when Van calls him Master. Van will often press these buttons on purpose.


  • In Blame It on the Brain, the question of why a dead man had fallen out of Fry’s apartment drives Leela to immediately return to Earth despite taking an important test, but the discovery that the man in the morgue who has been identified as Fry is actually Walt prompts her to mount a one-woman assault on Momcorp to find the answers.

Girls und Panzer

  • Boys und Sensha-do!:
    • For Akio, it's anyone treating members of their family poorly, especially casting them out of the family, which hits hard for him because he lost his father. He also dislikes Maho because he believes she is not there for Miho enough, but while Miho's defending her sister doesn't convince him, he doesn't press the issue.
    • For Shiho, it's having her personal honor questioned, as seen when she loses her temper when Saburo and Akio each give a "The Reason You Suck" Speech against her.


  • Hunting the Unicorn: If you mess with Kurt, Blaine will not hesitate to pick a fight with you. If you hurt Blaine, the Warblers will want to rip your kneecaps out. And if you sleep with sixteen-year-old Blaine, break up with him, and then string him along for weeks—without correcting his notion that Sex Equals Lovethen his brother will threaten to burn you alive.
    • Kurt doesn't take Blaine's kidnapping very well.

The Grim Adventures of Billy & Mandy


  • Company0051 has the The Captain of the eponymous Company. Basic inspection shows him as a calm, collected leader. Question how he runs the place, though, and he'll retaliate...

Hercule Poirot

  • From The London Syndicate, messing with Poirot's friend Hastings is this for the detective. He even gets into a physical fight during the events of The Rival Gang to try to protect him.
    • As Absent Without Leave shows, these sentiments are reciprocated entirely.

How to Train Your Dragon

  • In Black As Night, anyone mistreating Hiccup after he's blinded starts to set Astrid off; during the final lesson in Dragon Training, which pits her and Snotlout against the Zippleback, Astrid uses the cover of its smoke to hit Snotlout a few times for sticking Hiccup in the forest with his hands tied by his blindfold.
  • Still sore from Hiccup's (supposed) death, Stoick from Prodigal Son is quick to lose his patience when he is brought up in conversation.
  • While Hiccup in What Lies Beneath has given up defending himself from Berk's mockery and shaming, he will not tolerate it when it is directed towards Astrid or Zephyr. Snotlout learned this the hard way, getting punched in the face when he implied that the newborn Zephyr would be a "dud" like him.

The Hunger Games

  • In Some Semblance of Meaning, the usually timid Vale has a huge Berserk Button when it comes to people trying to hurt Kit. This sort of Big Sister Instinct has caused her to ally with him even though he's probably the weakest competitor in the Games, run through the bloodbath to reach him at risk of her own life, and let's not forget the time she furiously killed another tribute who attacked him. It's also safe to say that another of Vale's Berserk Buttons is Obsidian Citrine.
    • Speaking of Obsidian, he sums up his own Berserk Button quite nicely for us: "You don't hurt innocent things. That’s just wrong. You don't kill sweet, innocent, harmless things."

Inside Out

Jackie Chan Adventures

  • Queen of All Oni: Don't mess with Viper's hair. Just don't.
  • The Ultimate Evil and its sequel, The Stronger Evil:
    • You'd better not mess up with Shendu's "belongings". That includes Valerie Payne, Shendu's Other and love interest. If you cause her to nearly die or kiss her, he might kill you. Hak Foo learns this through Cold-Blooded Torture and Daolon Wong through a Cruel and Unusual Death.
    • As for Valerie, it's dangerous to disrespect books or try to hurt her extended family (the Chans) before her.
    • Jade hates it when Valerie lies to or keeps secrets from her and the others. Learning from Hsi Wu that Valerie knew about Jade's status as Hsi Wu's Other is a major example.

Katawa Shoujo

Kill la Kill

  • From Secret Sunshine, Ryuuko has three:
    • One of them is Satsuki and much of anything related to her, as the latter abandoned Kiko (who was two days old) and her, two years before the main story.
    • The second one is someone bringing up her weight, as Uzu finds out, when she threatens to beat him up.
    • The third one is her "sunshine" Kiko being unhappy and, as we can see, she will not take kindly to that.

Kim Possible

  • In The Ronless Factor, any topic relating to Ron becomes this for Kim after his death, inspiring extreme emotions ranging from anger to grief, and even after she learns that she’s still around as a ghost, that only adjusts her trigger to anyone talking negatively about him or anyone involved in his death, ranging from slapping Shego for calling Ron ‘the buffoon’ to beating up Drakken to such an extent that she broke his jaw.

Kingdom Hearts

Kung Fu Panda

The League of Extraordinary Gentlemen

  • It's a bad idea to mess with Elizabeth Quatermain's True Companions, because the rest of them will make sure you regret it. And it's a very bad idea to mess with Elizabeth herself, because Skinner might not let you live to regret it.

Left 4 Dead

  • In Left 4 Dead fanon, Louis likes pills a lot. Stealing his pills, or even having pills when he doesn't, will drive him into a frenzy.
  • Go ahead. Try harming Ellis in front of Nick. We bet he won't mind. The times whenever people do, Nick tends to become frighteningly enraged. When a robber smacks Ellis and threatens to kill the group, Nick was seriously considering killing her. And when Nick thought that Brenda ordered Jerry to kill Ellis, he went completely NUTS and tried to kill her with his bare hands.
    • Actually, just try harming any of the Survivors. The others will make sure that you regret it for the rest of your life.

The Legend of Zelda

  • In Malon's Epic Cow Delivery, if you value your life, do not ever insult Malon's mother. She nearly kills Ruto for calling her mother a whore.
    Malon: In any other circumstances, I would've pitied you, maybe even spared you. But you insulted the one person that I held most dearly. And for that, the punishment... is death. Malon Punch!
  • In The Legend of Zelda: The Wind Waker, if you're a monster, do NOT mess with Link's hat. Kalle Demos found that out the hard way after spitting Link's sword out and pinning his hat against the wall.
    Link: Right! That does it! No one messes with my hat!
    Kalle Demos: Oh, actually, I think I just did, greenie! AH HA HA HA HA HAAAAA!

The Lion King

  • A couple of examples in The Lion King Adventures:
    • Don't insult Nala in front of Simba. You will regret it.
    • In The Return of Hago, Simba attacks Hago after he dishes out an insulting speech to him.
    • In The End, the Writer jokes about Sarafina's death, causing Haiba to lash out. Sadly, this leads to his death.
  • In When Did I Become a Parent?, Timon does not react well to someone trying to harm Simba and in fact attacks the lion who does so.

The Loud House

  • In Mall Rats, Leni is normally a kind, if ditzy girl. However, when she sees three jocks bullying Lincoln, they go down HARD.

Marvel Cinematic Universe

  • Turning Tables: In Chapter 27, Peter loses it when he overhears someone call Pepper a gold-digger and Morgan a bastard.

Marvel Universe

Mass Effect

  • Under no circumstances should you point a gun at Joachim Hoch in the Uplifted series. Hanala'Jarva will ruin your day and not even feel an ounce of remorse for it.
  • Admiral Daro'Xen from Project Gethinator is Yandere for Shepard in a big way, and does not take kindly to anyone who suggests that she and he are not meant to be. When she is directly turned down by Shepard himself, who is less than pleased with her horrible experiments and is in love with Tali, goddamn, does she ever lose it.

Medaka Box

  • World As Myth: Kumagawa apparently got "a bit hysterical" when Zenkichi was almost drowned in mud by Tangeshima. It Makes Sense in Context.
    • Koga getting shot sends Medaka into War God Mode.

Mega Man (Classic)


  • Unlike in the show, Merlin never uses his magic to kill people in The Student Prince... until he realises Val is about to kill Arthur. When this happens, Merlin bends the fabric of space itself to get between them and creates a swarm of angry bees, which goes after Val. Merlin later says that he does not regret killing him.

Miraculous Ladybug

  • The Fair Folk in Spellbound really don't like being called "fairies". One of the ways Adrien notices how distant Chloe (a half-fae) is becoming is that she starts responding negatively to the word. Felix temporarily becomes sensitive to it as well after his experiences at the Samhain revel.

My Hero Academia

  • Heroes Never Die:
    • Izuku hates whenever anyone implies that anything serious is a joke. His entire life is nothing but a long, cruel joke, so he snaps at anyone who doesn't take things seriously enough. The first time he activates One For All is when Iida chastises him for muttering during the explanation of the exam. This also makes him even more annoyed at Todoroki's attitude than in canon.
    • Kaminari implies that Bakugo is gay for Izuku. That doesn't go well for him.
      Izuku: Ooh... he pressed the "Deku Button." Always a mistake.
  • In Juxtapose, one of Principal Nedzu's buttons is hit when Izuku tells him that because his grade school thought his Quirk was so useless, the teacher passed Izuku off as Quirkless and never assigned him a Quirk counselor. Because of how fundamental Quirks are to a child's growth, this constitutes nothing more than child neglect, and Nedzu is all but planning to bring the school up on every charge possible for that.
  • Bakugou in The Undead Schoolgirl: Dead Pulse has people who don't give their best effort. When Bakugou realizes Todoroki is only using half his Quirk, he's enraged that the other boy would "try to be the best while half-assing it" and goes against his previous intention to not use his bracer's full power, for fear of damaging the building.

My Little Pony: Friendship Is Magic

  • The Alarmaverse: Fluttershy gets angry when she thinks somepony is hurting her chickens—angry enough to terrify Ditzy.
  • A Kingdom Divided: After Diamond Tiara dies, saying anything bad about her to Silver Spoon is the best way to start a fight.
  • Bride of Discord: Discord himself has a couple:
    • Don't call him a freak or a monster.
    • Also, don't insult Fluttershy, not even his won reflection can get away with insulting her.
  • A Diplomatic Visit:
    • Swift-Pad, and wolves in general, have one - once an apology's been made, that's it, no further ones needed on that subject. Bringing it up again is considered incredibly insulting since it implies that the other person forgave them too easily or that they didn't know what they were forgiving. Twilight accidentally triggers this for Swift-Pad, but once he explains about it, she promises to do better when it comes to learning such things so she won't accidentally offend others like she did him.
    • Harming endangered animals such as phoenixes is also a major berserk button for Swift-Pad, and when he finds out some teenage dragons were trying to smash defenseless phoenix eggs (and tried to bully Spike into doing so as well), he promises to pass it on to his counterparts in the Dragon Lands so they can tell the Dragon Lord, who will punish the ones responsible.
    • Wolves feel rather strongly about parents who shirk their responsibilities and effectively abandon their children to the care of others. And they especially hate it when the caretaker is incompetent; they consider leaving a child with someone like that to be abuse on a criminal level.
    • Even if you mean well, don't ever tell Twilight to act against one of the qualities that Princess Celestia praised in her when she became an alicorn. Luna learns this the hard way in chapter 21.
    • Cozy Glow hits another of Twilight's in chapter 10 of Diplomacy Through Schooling when it's revealed she's actually an adult in the form of a filly and thus putting the other students in potential danger.
  • Getting Back on Your Hooves: Losing is one for Checker Monarch and has been since she and Trixie were foals.
  • Inner Demons: Once she's taken over by her Queen persona, it becomes a very bad idea to betray Twilight Sparkle. Or do anything that in her mind constitutes betrayal. Oh, and if you value your life, do not come between her and her brother.
  • In Legionnaire, just about everything pisses off the Khan religious authorities. Yes, they are Feeling Oppressed by Their Existence.
  • Loved and Lost:
    • When Princess Cadance is injured in the tenth chapter and the distraught Twilight Sparkle asks from the disgraced heroes — Celestia, Shining Armor, Spike and the rest of the Mane Six — how they could have put her former foalsitter in danger, Celestia tries to pacify her by saying they didn't know it would happen. In response, Twilight — whom Prince Jewelius has manipulated to stop trusting her friends, brother and mentor for their treatment of her at the wedding rehearsallashes out at them all, imprisons them in a magic dome, and coldly leaves them at Commander Hildread's mercy.
    • Jewelius really hates it when his cousin Cadance and/or aunt Celestia are openly praised/loved in his presence. This first shows when he's still pretending to be a nice prince; he glares angrily for a split second when Rarity praises the wedding of "the wonderful Princess Mi Amore Cadenza". After he has stolen the throne and made all the other heroes but Twilight public enemies, he gradually becomes more open about this. He eventually smacks Twilight in the cheek when she insists him to pardon all the fugitives, and when Canterlot's citizens demand the same thing, he decrees that anypony who sympathizes with the fugitives will be accused of treason and severely punished.
  • Apple Bloom from Moody Mark Crusaders will change your life into hell if you ever mention Applejack in her presence.
  • Progress: Don't break Luna's glasses. Just don't. Also don't threaten anypony under her protection.
  • Starlight Over Detrot: Taxi will put you in a world of hurt if you bring up her (lack of) cutie marks, and Swift flips out at the mere mention of Essies (Magically-made constructs).
  • The Vinyl Scratch Tapes: If you mess with one of Octavia's friends, she will beat the crap out of you. If you mess with Octavia, Vinyl will call you a jerk, go out of her way to humiliate you, and then have security (the Diamond Dogs) beat the crap out of you.
  • The author, Kalash93, has included a few throughout his stories.
  • In Epic Unicorn History The Beards Of Harmony, we are shown that if you do anything that harms Star Swirl's beard, anything at all, you should forfeit your life before he does it for you.
  • Shining Armor in the Stallions Of Harmony Verse does not appreciate saying bad things about his little sister.
  • The Wanderer of the North: Anything to do with Diamond Dogs is this to Nikóleva because of what they did to her father.
  • The Pieces Lie Where They Fell:
    • Rex does not like it when people think he's stupid due to just being a Diamond Dog.
    • Page gets very mad when it's implied that their hidden enemy is responsible for everything that's happened to her species, including the Fantastic Racism aimed at Changelings.
  • Pony POV Series:
    • Commander Bond gets pissed whenever Con Mane is brought up. Bond goes on a rant about how Mane is nothing but a mockery of real spies like him. Real spies don't go out in public in a Tuxedo and Martini, they stick to the shadows and risk their lives every day against real villains, not stereotypical cartoonish ones. This goes away when history is changed by Makarov getting Ret Goned, meaning Bond's spy parents are still alive. Bond is more jovial and enjoys Con Mane stories.
    • Chance, the Anthropomorphic Personification of Luck and Unpredictable Outcomes, cannot stand anyone cheating in a game of chance.
  • In Rites of Ascension, you do not want to express any tribalist leanings in Princess Celestia's presence, no matter your station (especially since alicorns are technically all three tribes). The only reason she hasn't made the fine for it two hundred million bits is because there is a legal maximum.
  • Inverted for Raindrops in RainbowDoubleDash's Lunaverse. Rain is pretty much the only thing that lets her stop being angry.


  • A major piece of the character development in People Lie is the three main characters slowly learning to overcome their individual buttons. Naruto overcoming the memories of his traumatic childhood, shown using his Shadow Clones to inflict pain on himself. Hinata, scorning Neji and the rest of her family but tempered by Naruto's influence, and Sasuke, given a tongue-lashing by Naruto and Hinata in order to make him refrain from snapping at the mention of Itachi.
  • Legacy of the Rasengan: Don't ever steal Naruto's jutsu. When Kakashi does it on accident, Naruto's willing to let it slide after he promises to never teach it to anyone. When Naruto sees Sasuke use it while fighting Gaara, Naruto drags Kakashi outside and is perfectly willing to put him in the hospital.
  • Escape From The Hokage's Hat: Sakura's is people calling her a "useless fangirl" and insulting Naruto. Heaven help you if you push this button repeatedly. Ask Kiba.
  • Chasing The Shadow: Never tell Sakura she can't do something, or for that matter say anything homophobic in front of Haku.
  • Kitsune no Ken: Fist of the Fox:
    • Don't waste pudding around Ino. She'll chase you all over Konoha High School and beat the crap out of you.
    • Don't destroy artwork that Sai has spent considerable time to make. Four bullies did it to a painting he'd spent an entire class period to make, in an attempt to intimidate him... and he ended up battering all four of them bloody and might even have killed one if Kakashi hadn't intervened.
    • Don't harm Ino and let Naruto find out. Period. He almost took off Aoi's head with an iron bar for it. Also, don't let him see you harm Hinata in any way, shape or form. He subjected Zabuza to a brutal beat-down and nearly cut his throat after Zabuza hit Hinata in the face and knocked her senseless.
    • Matsuri really, really does not like sex offenders, and will set you up to be killed, either by her own hand or someone else's, if she finds out you tried to rape someone or even gave tacit consent for someone else to be a rapist. It stems from her own traumatic past when her step-uncle raped her.
  • The Raikage: You can insult Naruto or his father all you want, but whatever you do don't insult his mother or any of his wives because if you do, you're dead meat
    • Don't insult or threaten Naruto in front of any Kumo nin, especially his wives.

Neon Genesis Evangelion

  • A Crown of Stars:
    • Shinji’s button is Asuka, and he is quite aware of it.
      Crush... destroy... kill... all of them. They hurt her. Make them PAY.
    • Asuka gets mad when someone tries to take Shinji away from her. After returning to their original timeline Rei presses that button constantly, sending Asuka in “apocalyptic” rages. In contrast, “people” as Winthrop, Jinnai or Barceló piss her off, but she displays cold fury towards them.
  • Advice and Trust:
    • When Leliel almost killed Asuka, calm, soft-spoken Shinji went berserker and tore it in pieces, roaring the whole time. Hurt her emotionally is also a very, very, very bad idea.
    • Hurt Shinji, upset him or try to take him away from Asuka and she will plot your demise and look for places to hide your corpse. And Rei will assist her.
    • Talking about Rei, threaten Shinji and Asuka in front of her and there will be nothing of you left after she is done with you.
      Rei: "You... will not... harm them... I... will... not... permit... it!"
    • Basically, the three main Pilots function as this for each other: harm any one of them in any way, and the other two will come down on you like the wrath of God.
      Rei: You will not touch them! Their bond is the most beautiful thing in this world! They love me and I them, and even I will not risk disrupting it! You will not ‘love’ them! You will do nothing that might disrupt it! DO YOU UNDERSTAND ME?
  • The Child of Love:
    • Misato is a very overprotective Mama Bear. Usually she acts self-controlled, calm and respectful when in presence of a superior. When she heard Gendo was scheming something might kill one of her wards and would hurt the another she walked in his office to put a bullet in his head.
    • Rei is unemotional and collected... but where her niece is concerned. Threaten Teri and she will snap and will crush you.
  • HERZ:
    • Asuka has several buttons, most of them related to her husband: Do not flirt with Shinji, try to steal him away or act pervert around him. Asuka will ensure it is hazardous to your health. Do not poke fun at her relationship with Shinji, suggest to her face they have S&M sex or make Nazi jokes around her. Kurumi is constantly pressing the first button. Kensuke gleefully punches the second one every time he opens his mouth.
    • Rei. Threatens her niece’s life and she will liquefy you. Not a hyperbole.
  • The One I Love Is...: Do not even think about hurt or harm Asuka or Rei in some way, shape or form. Shinji… will not be nice to you. Unfortunately for them, the MP-Evas did not get the meme.
    Shinji: "Die... die... die... die! Die! Die! You monsters! You killed Asuka! I'll kill you! Kill you! I'LL KILL YOU ALL!"
  • Evangelion 303:
  • The One I Love Is...: Do not even think about hurt or harm Asuka or Rei in some way, shape or form. Or else Shinji… will not be nice to you.
    • Zeruel found out the hard way.
    • And later when he saw the MP-Evas munching the last remnants of Unit 02 he went utterly nuts and tore them apart savagely.
  • Scar Tissue: Do not insult Asuka, do not pick on her, do not threaten her and do not hit her in presence of Shinji. If you do so much as badmouthing her or being rude to her, Shinji... will snap.
    "How dare you threaten my Asuka?!" Shinji slammed his foot against the beast's chest, forcing it to drop its grip on his throat and step back.
  • The Second Try:
    • Taunt Asuka with her daughter's name or threaten to harm Shinji in front of her. Come on! I dare you! When Gendo tried this, he was a tad bit surprised when she lunged at him and nearly got her hands around his neck.
    • Likewise, Shinji doesn't take too kindly towards anyone who tries/threatens to harm Asuka. While he's pretty good at keeping his cool, some MP-Evas found out the hard way what happens if this button gets pressed too hard. Stupid bastards never saw it coming.

Once Upon a Time

  • Mr and Mrs Gold: Any parent that abandons their child is considered a bastard in Gold’s books. Even with Belle safe and sound, he does not take it well when she uses the chipped cup to feed a cat either.

One Piece

  • This Bites!: Cross has a great habit of stomping on these to get people all riled up.
    • Do not insult Tashigi's womanhood if you have any interest in not being castrated.
    • Do not insult Emporio Ivankov in front of Mr. 2.
    • Do not disparage Donquixote Doflamingo in front of Bellamy, or worse, tell Bellamy that Doflamingo will never respect him.
    • Do not touch Nami's tangerine trees unless you have her express permission. Soundbite apparently took a single leaf once in the past, and whatever happened put him off of them for good.
    • Do not insult Sengoku's choice of goats as a pet. Not even if you're Akainu.
    • Do not mention "sins of the father" anywhere near Ace unless you want to be extra crispy.
    • Do not look down on Jabra because you think he's weak. He gets enough of it from Lucci, and it really gets under his skin.
    • Do not make light of a life-or-death struggle in front of Kalifa; she takes her assassination work very seriously. And thanks to Cross, really don't call her "bubbly".
    • Amazingly, even the Dirty Coward Smug Snake Spandam has one: Do not insult his father.
    • Cross himself has a few of his own: Do not call him any variation of Jeremiah, and do not mess with Soundbite.
      • Spandam's entire existence. Cross absolutely and completely loathes him, to the point of telling the crew point blank that he would have no issues in killing him.
    • Soundbite takes offense when people treat him as less than sapient. He'll bite anyone who calls him a "pet". He's a full-fledged Straw Hat pirate and Cross' partner, thank you very much.
  • Luffy's Renewed Adventure:
    • Luffy obviously has the canon one of his hat. He also, however, has an almost uncontrollable hatred towards Blackbeard and Akainu. He doesn’t think highly of Wapol and his disgraceful ways as a pirate either.
    • DO NOT so much as remind Alvida of what she used to be, let alone insult her about it.
    • Usopp retains his canon one as well: the one thing that can snap him out of a hopeless, Screw This, I'm Outta Here! stupor in the face of extremely powerful enemies is mocking Luffy. Mr. 4 and Miss Merry Christmas discover this the hard way, and it also reaffirms Chopper, Valerie, and Greg.
  • Second Wind:
    • Crocodile doesn't take mockery well at all, but the one thing that pushes him over the edge faster than anything else is bringing up his defeat at the hands of Whitebeard.
    • Sanji struggles against Mr. 1 up until the point where he injures Nami, who screams as a result. Then comes the Diable Jambe No-Holds-Barred Beatdown.
  • In Supernova One Piece, Zoro rips Tashigi a new one when, like Kuina before her, she attributes her loss to women being weaker than men. Besides reminding him of his dead rival, it's an insult to his skill that he won simply because of his gender.

Phineas and Ferb

  • In any piece by KicsterAsh, insinuating that Phineas "cracks" when not allowed to sketch and/or invent. Given that it's Phineas Flynn, it's more adorable than anything else.


  • Wheatley, in the Portal 2 fanfic Test Of Humanity, still hates being called a moron. However, it's also a very bad idea to say he's anything like the HAL 9000 or GLaDOS. And, whatever you do, don't you dare hurt Chell or imply that he can't feel love because he's not really human. He may be a Gentle Giant cyborg in the fic, but he won't hesitate to punch you in the eye (as GLaDOS found out) if you so much as harm one hair on the girl he loves.

Power Girl

  • A Force of Four: Don't remind Badra that she was an one-time villain who disappeared after Wonder Woman kicked her butt once. She'll not take it well.

Power Rangers

  • Sean O'Callahan is a walking one in Power Rangers GPX, particularly in the form of Daisuke Miyazawa, who keeps pushing it to his detriment. Eventually, Daisuke pushes it so much that after he mutinies, he gets a massive punch from Sean and a big earful. He calms down more in subsequent episodes, but he keeps it subtle, especially in an alternate universe version when his alchemist enemy compares his alchemy to Clarke's Third Law.


  • A New Chance Series:
    • For any of Ash's Pokemon, it is threatening his well being. Only now he has a Latios and Latias in his collection, and they are rather attached to him. The Fearow finds this out the hard way, when Pidgeot decks him after he tried to kill Ash.
    • Bianca has several. Don't ask her out in a perverted way, as Brock found out. Don't hurt Latios and Latias, and because of that she chews Ash out every time he uses them in battle.
    • Don't call Latios an unimportant Legendary. Don't separate a child from his mother. Rico, who sold Larvitar's mother, pays the ultimate price.
  • Black Albino: Don't come talk to Kuu about how darker Nidoran are stronger, faster, smarter, overall awesome, and bound to lead. No matter he's the darkest possible a Nidoran can be. That his mother was killed because of it doesn't help things.
  • In Cori Falls's fanfic series, insulting or harming Jessie is this for James (Domino found this out the hard way). For Jessie, it's insulting or harming James or saying anything bad about her deceased mother (Misty found this out the hard way). And the existence of Ash Ketchum, of course.
  • Pokémon × Nimja: Play the Game: "I'M NOT A GIRL, YOU PESKER!" For context: in the web series based on this fanfic OGiNiM is played by a girl, who (due to admitted vagueness by the author for the audition) made no attempt to make him sound like a dude. Though she rerecorded the lines in a more male voice, the author loved the original voice so much that she asked the woman playing him to keep it and put this gag into the fanfic in "Nevermore" as a result.
  • Pokémon Reset Bloodlines has these:
    • For Ash, people abusing or hurting Pokémon in general has always been one, but when Paul blasts Primeape into the sky, possibly with fatal results, this sets him up into a full-blown Unstoppable Rage against the perpetrator. He seems to be developing another; namely, threatening Misty and/or Iris.
    • Misty really, really hates Pokémon thieves. She also can't stand seeing Water-types being hurt or abused by their trainers.
    • Giovanni doesn't like Juan. At all.
    • For Koga, it's jetpack ninjutsu, of all things.
    • The Draconids can't stand the sight of Fairy-types, and have little if any tolerance for Sootopolitans.
    • Azalea Town's collective one seems to be stepping on a Slowpoke's tail, like in the anime.
  • Pokémon: Take Two: A good tip for dealing with the lead of this Send Your Original Characters fanfic: In the name of all that is holy, if your name isn't Ry, do not, under any circumstances, call Raion Ryhorn. Just... don't. There are better ways to commit Suicide by Cop.
  • Return of the Hero: Do NOT call Rosa "Rose" or "Rosie".
  • Tales Of Faith: If you are a guy and state anything about Cress's flat chest, regardless of whether she's a Flaffy or Ampharos, prepare to receive either the end of her sledgehammer or a suplex if she's drunk.

Pretty Cure

  • Yoko in Futari Wa Pretty Cure Blue Moon cannot stand destruction of property and is often set off ranting about it... like the time she walked up to the Monster of the Week in the middle of a battle and lectured it about the mess it made. Oh, and you might not want to remind Kainatrol of her sister unless you know what you're doing.
  • Futari wa Pretty Cure Dragon: The man in black does not like being called a "super spade" simply because he acts like a stereotypical Mexican even though he isn't Mexican in any sense of the word. Go ahead, call him that three times. He'll go batshit on the poor sap who's unlucky enough that the third instance of that phrase in a single episode comes out of his mouth.
  • In The Pretty Cure McLaughlin Club, Honoka does not like when people bring up scientific myths and act like they're real.
    Honoka: 10% of my...? Don't tell me you've been watching Lucy again!


  • Old West:
    • Grace Glossy is a civil woman, but when Bad Bill's gang beats up her son Teddy, she viciously owns them.
    • Rattlesnake Jake dislikes liars, which is one of the reasons he can barely tolerate the habitually pretentious Sheriff Rango. When he witnesses the vicious beating Grace gives Bad Bill's gang, he becomes very angry with the woman who has acted superior towards him due to her law-abiding attitude. When she confesses that she killed the robbers who smashed nearly all her eggs as an explanation to why she's so prejudiced towards outlaws such as Jake, he calls her a hypocritenote  and leaves in disgust.

Ranma ½

  • When Shampoo learns that Mousse has been throwing their fights in Ranma: Happenstance Gone Right , she's outright furious as it's an insult to any warrior for another to face them with anything but their full ability.

Real-Person Fic

  • Harm an animal, or one of the others, around Paul in With Strings Attached and he may quite violently stop being an Actual Pacifist... though he has such a horror of hurting anyone that it's not too hard to talk him down.
    • All of the four have a Berserk Button if one of the others is threatened. Certainly John laid some heavy (tho' nonlethal) offscreen water whoop-ass on a handful of Raleka after George was badly injured falling through a roof. No matter that none of the Raleka had anything to do with this... but they were approaching in a slightly threatening manner.
      • Given that John had just been awakened from an enchanted sleep by George peeing on him through said roof, had no idea what was going on save that it was bad, and was pissed as shit, he seems justified in attacking anything that moved at that point.
    • The only time in the book that Paul followed through on an attack was when the Hunter's BFG threatened the others.
    • Ringo immediately threw As'taris back when he threatened John.


  • In Patience, nothing can faze Pyrrha...except for her unrequited crush on Jaune, which he is unaware of. Simply bringing it up causes her to get very angry very fast.
  • Professor Arc: Jaune has gained so much popularity among Beacon's staff and students, that they'll react poorly to anyone who harms or hurts him in anyway. Blake becomes visibly enraged when Jaune's sisters vocally belittle the guy, and barely holds herself back from attacking them, and from intervening in Jaune's fight with his father. Even Pyrrha can barely contain her contempt for them.
    • This becomes viciously exploited by Cinder and her crew. She has Jaune arrested by General Ironwood, which stirs up enough anger and distrust by the citizens of Vale toward Atlas, that it attracts Grimm. Emerald uses her powers to have Pyrrha hallucinate Penny making damning remarks about Jaune during their fight in order to manipulate Pyrrha into destroying her in a rage.
  • A Rabbit Among Wolves
    • Cinder Fall, the selfish egomaniac she is, goes into cup-shattering fury when Jaune indirectly puts her on hold.
    • Qrow barely holds himself back from attacking a police officer who used a racist slur.
  • In Tending to the Soul, don't read Jaune's journal or bring up his family or past, particularly his failure to get into Beacon. His Tranquil Fury when he catches Neo reading his journal is enough to momentarily scare her and earn her respect. Jaune's reaction to someone pressing one of his buttons is downplayed in that he'll then apologize and offer them a free drink.
  • White Sheep (RWBY): After the Battle of Beacon, Adam's faction of the White Fang turns into a crazed cult worshiping him. Blake, Adam's ex-girlfriend who hated Adam even before this mess, noticeably twitches every time someone mentions him. At the Battle of Haven, Ren takes advantage of this by telling Blake "trust in Adam, and he will watch over you." Blake screams and starts killing everything in sight.
The Sentinel
  • A common sentiment in The Sentinel's fandom is "The only thing more dangerous than a Sentinel whose Guide is threatened is a Guide whose Sentinel has been hurt."

Sherlock Holmes

The Smurfs

  • Empath: The Luckiest Smurf: In the alternate timeline of Papa Smurf being married to Smurfette, Sassette dares mention that Empath is the one who truly loves Smurfette to Papa Smurf, and Papa Smurf slaps Sassette in the face for it, just having disowned him after he and the other Smurfs exiled the married couple and their child and then were trapped in time!
    • And in turn, Papa Smurf slapping Sassette becomes one for Smurfette, who promptly ends up leaving him and taking their daughter with her.

A Song of Ice and Fire

  • Lady Stoneheart in The North Remembers is cold, emotionless, to the point of being dead both figuratively and literally. Whether it be hanging Freys or witnessing a failed trial-by-combat or the reunion with her missing daughter, Stoneheart never so much as makes an expression of relief, satisfaction, rage, or sorrow. However, during her little reunion with Littlefinger, the man responsible for literally everything that happened to her family over the story, he makes the mistake of mentioning the Red Wedding and how it was only meant for her son Robb to be killed and for her to be ransomed back into his hands. She completely loses her shit and unleashes herself upon him, strangling the guy and nearly killing him before being stopped by her daughter Sansa.
    Lady Stoneheart: "Robb? Robb! ROBB!"

Sonic the Hedgehog

  • Don't tease Tails in Journey Into Darkness about Cosmo's death if you know whats good for you, Shadow learned this the hard way.

Soul Eater

  • In Breaking Point, Maka and Crona's biggest ones are anyone trying to harm the other. Violently Protective Significant Other is in full force in this story.
  • In Oblivion, Medusa smacks her younger sister Shaula around, and insults her fighting skills, plans, intelligence, and general competency, and Shaula remains relatively controlled through all of it. The second Medusa implies that Shaula was The Unfavorite to their parents, she immediately loses her shit.
    Medusa: You see? I told you, you're too slow and too weak.
    Shaula: So is that why Mother preferred me over you when it really mattered?
    Medusa: (immediately loses her shit and rams her sword almost into Shaula's face) You want to say that again, you little - ?!

Star Trek

  • In Insontis II, according to McCoy, one of the few things that can make Kirk lose control in front of crewmen is any threat to "their (currently fun-sized) Chief Science Officer and said science officer's precious dignity."
  • In the fic Written in the Stars, Jane Kirk is a capable, level-headed Captain and generally a nice girl. But like her male counterpart, harming her crew is a bad idea, particularly Spock. This goes for her Prime counterpart, too. Added to that in this particular story, she gets pretty pissed in the first half whenever her counterpart makes not-so-subtle suggestions that she's gaining feelings for Spock.
  • Worffan101's recurring Star Trek Online character D'trel ir'Aehallhah tr'Rihannsu has a pathological hatred of the Tal'Shiar that tends to make her go on Roaring Rampages of Revenge at the mere mention of them in a positive light. (Many years before, a Tal'Shiar secret police unit destroyed a Unificationist group of which she was a member, including her lover Adani, whom they raped to death.) First exploited, then subverted in Peace Forged in Fire:
    • Exploited by Colonel Merik tr'Kiell, who intentionally provokes D'trel into Berserker mode by speaking fondly of two other Tal'Shiar, one of them being Hakeev. He was luring her into her customary berserker charge so he could trap her ship and kill her. But he underestimated how much gun Praetor Velal had brought along.
    • Subverted after Merik's ship is disabled. He claims to have been one of the men who raped D'trel's lover Adani to death, to get her to destroy his ship to deny intelligence to the Republic and Empire. It backfires: D'trel decides death by exploding starship is too good for him and Merik is taken alive.

Star Wars

  • In one Knights of the Old Republic fanfic, Saul Karath isolates Carth while his Dark Jedi honor guard interrogates Revan and Bastila. After trying the We Can Rule Together tactic (which fails miserably), he proceeds to test every Berserk Button Carth has. Carth holds it together pretty well, until Karath mentions what he plans on doing to Mission...
  • While Jinn, from Star Wars: Light In Dark Time, is already a bit Ax-Crazy to begin with (he's basically a sith convincing himself he's a Jedi), however, comparing him to Palpatine is just too far. Similarly, hurting his friend's, especially Leia, will make Luke explode.
  • In three stories by Caro June, Imperial guards find out how bad an idea it is to rough up Leia right in front of Han. In Going Solo, one of the guards decides to 'distract' Han by smacking Leia. In The Way It Should Be, one of the guards makes clear his intent to rape Leia. Both scenes have the same result: Han rushing them in blind fury, despite being severely injured, grabbing the guard's neck in a vice grip that probably rivals Vader's. He would likely have killed the attacker both times, but in both stories, he's cold cocked a second later. In "The Way", it happens again later on, with a guard slapping Leia and Han blindly reacting, this time punching the guy hard and knocking him to the ground before the other guards grab him and restrain him. In her story The Princess And The Pirate, Leia, along with Luke, is Force-less and rather weak from the use of ysalamris. This makes Han more worried and even more protective of Leia than normal. He headbutts a guard who hits Leia when she stumbles, and at one point, she's hit with a heavy stun. Han, not knowing if she's stunned or dead, goes into a wild rage, lashing out with everything he has. He still gets dragged off and beaten, though.
  • Speaking of Qui-Gon, the fic The Marionettes Dance has him getting into an Unstoppable Rage trying to protect his unconscious apprentice Obi-Wan. The first time, he slices various limbs off four guards after having used a Jedi Mind Trick to fool them into ignoring his lightsaber. Later, he's really set off when they lie and say Obi Wan died. He crushes one guard's throat but doesn't kill him, then does kill two more with his bare hands. The first guy gets a piece of nasal septum driven into his brain courtesy of Qui-Gon's elbow slamming into his face, and the second guy gets his neck snapped after Qui-Gon choke holds him and forces him to admit that Obi Wan is still alive and where he's at. He may have felt he had no choice but to kill that one, he was wielding a box that controlled shock collars that both Jedi had been forced into wearing, and the Electric Torture was really ticking off Qui-Gon already.
  • In Important Information, the alien who spent a couple of weeks brutally torturing Han Solo decides to taunt Leia when they meet by showing her through the Force what she did. The result is Leia promptly screaming and charging forward to battle with her lightsaber. The alien, Lakaya, may have underestimated the Princess, who ends up skewering Lakaya with her lightsaber. Meanwhile, Han, despite being half dead and barely able to move, sees the guy who arranged the whole thing in the first place, and a combo of Luke's force boosting his strength and his own adrenaline allow him to get up and confront the guy. He almost gets killed by a Stormtrooper, but takes out that trooper, another, and the guy behind it all before collapsing from his injuries.
  • In Worst Vacation Ever, someone pulls a You Killed My Father with Han, and despite his attempt to explain that it was Darth Vader and not him, she shoots him in the arm. After he's on the ground, Leia comes over and is told to move if she doesn't want to die with him. Leia reacts by going into Violently Protective Girlfriend mode, snarling, lunging at the woman, and giving her a No-Holds-Barred Beatdown. "No one hurts someone I love" is her remark afterward.
  • Mara Jade is raped in The Unthinkable, and Luke nearly goes all the way into The Dark Side mode, viciously force-choking her attacker. He stops only when Mara and Han beg him not to kill the guy, and Mara says afterward that she was scared by it.
  • Both Han and Leia's Berserk Button gets pushed in Welcome Back Your Dark Memories. Han and Leia are in a tapcafe and a guy from Jabba's Palace happens to be there. He makes lewd remarks about Leia, and Han gets into a knock-down drag-out fight with the guy. They separate, and Leia moves in to tell Han it isn't worth it. But then, the guy breaks out a blaster to shoot Leia and makes another remark, and she pulls a Vader, blocking the guy's shot with the Force, then Force-choking him until Han has to tell her it isn't worth it to kill him. Battle Couple indeed.
  • AU fic Mara's Right Hook: A reporter asking nasty questions about the Skywalkers brings out Mara's Mama Bear when Ben is brought up. Mara clocks her so hard her jaw dislocates.

Stargate SG-1

  • In What You Already Know, as Daniel’s powers develop, threatening the rest of SG-1 is a quick way to get on his bad side, to the point where even Daniel is scared of what he’s capable of when a Kull warrior injured Sam and he retaliates by burning it to death inside its indestructible armour.

Steven Universe

  • In Gift of A Diamond, Blue Diamond snaps at Yellow Diamond when she requests the Human Zoo and all of the gems and humans in it destroyed, Blue seeing it as an insult to their fallen sister.
  • In Learning to Breathe Underwater, the Crystal Gems won't tolerate anybody badmouthing Rose Quartz, espcially in front of Steven. Also, due to her time in the mirror, Lapis utterly hates being told what to do.


  • In Hellsister Trilogy, NEVER make puns out of Darkseid's name. The Dread Lord has NO sense of humor and doesn't mind obliterating the perpetrator since he can bringing the loud-mouthed idiot back to life as many times as he wants.
    "Fitting, indeed," said the assistant. "To have taken the Supergirl-clone from her imprisonment, Boom Tubed her to a point one year in her future, kept her comatose until her child's delivery, then sent her back to confront the Supergirl... a stroke of genius."
    The assistant grinned. "Why, you might even say, Dread Lord, that the Satan Girl was Supergirl's dark—"
    The master whirled and swiftly pierced the other's gut with the spear he was holding. The Spear of Destiny.
    Desaad clutched at the shaft transfixing his midsection in agony. His master shot forth beams from his eyes which reduced him to his primal atoms. Later, he would reassemble them, and trust that Desaad would learn by that not to make jokes using his name.

Super Mario Bros.

Total Drama

  • In The Legend of Total Drama Island, Chris gets genuinely angry—something he rarely does—when Sadie tries to guilt him into letting her switch teams by accusing him of discriminating against her because she's fat.
    Chris: If you play the ‘oppressed minority’ card on me again, you’ll be out of here so fast it’ll make your head spin. Capisce?”
  • In Monster Chronicles, Cedric hates when he's mistaken for his Cockney accent his mistaken for an Australian one. But that's nothing compared to what he'll do if you knock off his top hat.
  • Total Drama All-Stars Rewrite:
    • Harming wildlife is a quick way to piss off Dawn.
    • Owen hates being called useless.
    • Gwen really hates it when Chris calls her Gwendolyn
    • Based off his reaction to Leonard calling it a spell, Mike gets pretty offended when his disorder is treated lightly.
  • Unbreakable Red Silken Thread: Anyone insulting Cody in front of Heather. She even was about to confront Jasmine when she insulted Cody in chapter 11, even though Jasmine is at least three feat taller than her, and in chapter 15, smacked Gwen in the face for insulting Cody.


  • Amongst Touhou fans, a lot of portrayals of Sakuya have her react incredibly violently if anyone implies that she pads her bra, or even writing or thinking the word "pads". She also doesn't like people who sleep on the job, which is bad news for Meiling. None of this, however, comes close to what she'll do to you if you mess with her ojou-sama, as Yukari found out in Koumajou Densetsu II.
    • Cheating Reimu out of donations is one of the surest ways to piss her off in fanworks, and has been the source of more than a few "Digging Your Own Grave" pics on Danbooru.
    • Patchouli likes to Throw the Book at Them on occasion in the fighting games, but as Musou Kakyou: A Summer Day's Dream demonstrates it's not a good idea to do the same to her. When Aya does this accidentally, it sets up a big throwdown between her and Reimu.
    • Calling Yukari any variation of "old hag" is a good way to be sucked into one of her gaps. She's 17, after all.
    • Very few things can piss Yuyuko off, but two things, according to fanworks, will do it: interrupting her meal may get you put through a wall, but stealing her food will make her go Hollow on you.
  • In the Gensokyo 20XX series, do NOT call Yukari a whore, as she will make you wish you didn't.
    • A minor one that Yuuka has is being rude to her (like shouting at her and, if you're a child, calling her a bitch) and, as we recently find out, apparently dealing harm to Ran and Reimu is also this.
    • Yuyuko does not like being "fucked over".
    • Apparently, an age-regressed Reimu doesn't deal with wangsters too well and, if you deal her pain, she deals it back

Touken Ranbu

  • Tales of the Undiscovered Swords: You can hit Hinata Aoe anywhere you like, but do not touch his ornate obi sash. The only one seemingly managing to do so with no dire consequences is his brother Juzumaru, who only gets "vocal, noisy protest".
    Hinata: I don't care even if you stab my heart, but the second you touch my obi, you're as good as dead!
Toy Story



  • Son of the Black: Do not mentions his father around Jim. Steve tried taunting him with it and wound up being carried away in an ambulance.



  • In The Land of What Might-Have-Been, whihle Elphaba still dislikes being used, but she controls it because she has to concede that the Mentor is right that there's nothing else they can do but help her against the Empress.
    • After spending time with Dorothy, the knowledge that Dorothy has handed herself over to the Hellion prompts Elphaba to immediately fly into a rage and resolve to find the Hellion to rescue Dorothy.


  • Quicken: Lisa is a nice, kind girl most of time, but don’t ever pry into her past, or she’ll use her power to pry into your head.

The World Ends with You

  • Eri, Shiki's best friend, in Eri's Game will attack anyone who tries to hurt or insult Shiki. The beating with Beat, who is a Reaper, really does it.


  • X-Men: The Early Years: For the love of God, DON'T diminish biochemistry and Twinkies to the face of Hank McCoy. Your demise will not be quick or painless.


How well does it match the trope?
