History SirSwearsALot / FanWorks

* ''Fanfic/DanganronpaParadiseLost'': Shun is noticeably far more prone to swearing compared to the other students. An examples comes in his response to Monokuma informing the students that [[ClosedCircle they are trapped in the facility]]: while the others do protest, Shun is the only one to use profanity, calling Monokuma a "son of a bitch".

!! ''WesternAnimation/{{Luca}}

!! ''LightNovel/ACertainMagicalIndex'' / ''Manga/ACertainScientificRailgun''

!! ''WebVideo/TheAngryVideoGameNerd''
* In ''Fanfic/ASagaOfParallelWorlds'', the Nerd swears like a sailor, and was like this even as a teen.

!! ''Machinima/RedVsBlue''

* ''Fanfic/AmazingFantasy'' has both Bakugou and the Prowler. The former is known for his HairTriggerTemper and ends up FlippingTheBird at Mysterio while continuing to mock him for his obsession with killing Peter. During her fight with Peter, she also curses up a storm out of frustration, but Peter couldn't [[LanguageBarrier understand a lick of it at the time.]]

!! ''Anime/MyHime''
* In ''Fanfic/PerfectionIsOverrated'', Hitomi Kirihara, a deconstruction of a JerkSue, swears significantly more than the other characters to reflect her abrasive personality and refusal to comply with social norms; she's essentially impossible to get along with when she's talking with other people instead of killing them. Natsuki and Nao also have a fair amount of profanity compared to the rest of the cast.

* The ''FanFic/AngelOfTheBat'' trilogy features plenty of dirty-mouthed characters, but ComicBook/JohnConstantine is the most vulgar of the bunch. Tellingly, religion-based curses are usually treated as particularly taboo in the trilogy, but Constantine ends up shouting, "Jesus Christ!" in the story's first chapter.

* In the ''VideoGame/StarTrekOnline'' fic-verse that started with ''Fanfic/{{Bait and Switch|STO}}'', the main viewpoint character Captain Kanril Eleya swears like a sailor, appropriately enough. Rarely does a chapter pass without a "''[[PardonMyKlingon phekk]]''" or "''[[PardonMyKlingon sher hahr kosst]]''". Other characters are more restrained, though there's still the occasional PrecisionFStrike.
* In the ''Harvest Moon DS'' one-shot ''Fanfic/BestFriends'', the angry POV character Claire curses every other sentence.
* In ''Fanfic/IncarnationOfLegends'', Despite her gentle, serene public persona, Brunhilde's true personality is coarse and gritty, swearing up a storm wherever she goes.
* Melanie Black, Mercury's mother, from ''Fanfic/TheBlackHearts''. Not only does she provide most of the profanity in the fic, but she also ends up being the most foul-mouthed character in the series she comes from, ''Fanfic/TheMakingsOfTeamCRME''. She's the only one liberally using f-bombs whereas only a handful of other characters actually even use one.[[note]]Surprisingly, it is Cinder of all people who uses two in the whole series.[[/note]] [[spoiler: Even her short appearance in ''Fanfic/{{CRME}}'' had her swearing up a storm even though she didn't use any f-bombs then.]] [[spoiler: Later on, [[MasterOfIllusion Emerald]] makes an illusion of her and just about every sentence she utters has a swear word in it.]]
-->''Mom always had a way with words.'' '''- Mercury's narration in ''The Black Hearts'''''

* Cristina from ''Fanfic/TheCutOfYourLoveNeverHurtsBaby'' spends a good chunk of her dialogue cursing. It's especially noticeable because no one else curses.
* ''Fanfic/ADiplomaticVisit'': Chapter 8 of the sequel ''Diplomat at Large'' notes that Squirk, the monstrous octopus who once ruled what is now Aquastria, has quite the mouth on him, though readers are spared any examples. His prison is specifically enchanted so the nearby residents don't have to listen to his words.

* ''Fanfic/{{Essence}}'': One of the Officer Jenny's that Ash meets has a crude mouth, though she also uses "[[GoshDarnItToHeck friggin']]" a lot.
* In ''Fanfic/ForestofDespair'' both Akita and Mitsuru talk like sailors compared to rest of the cast. This is even lampshaded by Akita herself.
* ''Fanfic/KingdomHeartsPsiTheSeekerOfDarkness'':
** Kairi is portrayed as this, which she justifies with the fact that she grew up in a port town, though Riku is rarely shown swearing and Sora is only known to have done so once between chapters.
** Vanitas also stands out, since he's the only character able to swear around Sora (there's a partially self-imposed NarrativeProfanityFilter around him which even Kairi is happy to adhere to).
* ''Bubbles'', of all characters, is this way in the ''WesternAnimation/ThePowerpuffGirls'' fanfic series ''Fanfic/{{Ladder}}''. Despite being normally innocent, she curses quite a sum, especially [[spoiler:when she goes into her seizure-like states]]. It's very uncharacteristic of her, so Professor Utonium thinks it's a result of [[spoiler:brain damage caused by bringing her back to life]].
* ''Fanfic/MyImmortal'': No one other than Ebony Dark'ness Dementia Raven Way.
-->'''Enoby:''' What the fuck? You torture my bf and then you expect me to fuck you? God, you are so fucked up you fucking bastard.

* In ''Fanfic/PerfectionIsOverrated'', Hitomi Kirihara, a deconstruction of a JerkSue, swears significantly more than the other characters to reflect her abrasive personality and refusal to comply with social norms; she's essentially impossible to get along with when she's talking with other people instead of killing them. Natsuki and Nao have a fair amount of profanity compared to the rest of the cast.
* Ash's Primeape in ''Fanfic/PokemonResetBloodlines'' is revealed to be this when they reunite. He curses a lot during the gym battle against Blaine, but Ash and the narration [[NarrativeProfanityFilter refuse to delve into the specifics.]]
* In ''Fanfic/PreludeToChorus'', Felix provides almost all of the profanity in the fic. Only four swear words are uttered by people other than him. Even his internal monologues are littered with profanity. He still swears a lot in the sequel, ''Fanfic/SoulClefXI'', but there are more characters providing profanity other than him.
* In ''Fanfic/SakiAfterStory'', Teru and Sumire do most of the swearing, with Teru having anger issues, and Sumire calling Teru's claims that ''Manga/{{Saki}}'' is not her sister "bullshit".
* In ''Fanfic/ASongOfGrumblingAndCottonCandy'', Pizzazz can barely go a few sentences without cursing.
* In the ''Franchise/SonicTheHedgehog'' DarkFic ''Fanfic/PrisonIslandBreak'' cursing is common, but Shadow is particularly coarse, to the point that he makes "fuck" cease to have any more meaning than "said".
-->'''Shadow:''' [[OhCrap Aw, fuckaroonies.]]

* ''FanFic/SoulsReborn'': Ginta, who was taught how to talk by sailors. The ironic part? [[spoiler:He's ''Gaara's'' reincarnation]].
* In ''[[https://www.fanfiction.net/s/13022747/1/ Treefall]]'' and its sequel ''[[https://www.fanfiction.net/s/13081769/1/ Sunrise]]'', although almost everyone tends to use swear words when they are in the face of conflicts (including the teachers who are supposed to be role models for young generation!), no one quite compares to Frenda Seivelun and Misaka Mikoto in terms of vulgarity.
* The main character of ''Fanfic/TheTwilightChild'' is mentioned as swearing a lot, but the NarrativeProfanityFilter and HoldYourHippogriffs usually stop her from saying anything truly offensive, though she does get in a "bastard" at one point. However, when she's truly at the end of her rope, she prefers to unleash the foulest word she can think of: "[[Literature/TheHitchhikersGuideToTheGalaxy Belgium.]]"
* Veronica "Ronnie" Weasley, a {{Gender Flip}}ped version of Ron Weasley from the fic ''Fanfic/WeasleyGirl'' is about as fond of swearing as her canon male counterpart, but gets censored a lot less and is allowed to drop a few F-bombs:
--> ''"I'LL KILL THAT FUCKING BASTARD!"'' [[spoiler:Said about Voldemort/Quirrell, after he's placed her under the Imperius curse and Harry manages to break her out of it.]]

* In ''Fanfic/WhatTomorrowBrings'', Tom spends most of his first chapter mentally swearing at Temrash.

* In ''Fanfic/{{Origins}}'', a ''Franchise/MassEffect''[=/=]''Franchise/StarWars''[[spoiler:[=/=]''[=Borderlands=]''[=/=]''[=Halo=]'']] MassiveMultiplayerCrossover, Jack is noted to be this, but, as in [[VideoGame/MassEffect3 canon]] she has to keep it down around her students, since there is an actual SwearJar. To further lampshade her status, most of the other characters keep their cussing to a minimum.

* ''Fanfic/ChildOfTheStorm''

* ''Fanfic/KingdomHeartsPsiTheSeekerOfDarkness'' portrays Kairi as this, which she justifies with the fact that she grew up in a port town, though Riku is rarely shown swearing and Sora is only known to have done so once between chapters.

* In ''Fanfic/{{Eleutherophobia}}'' Tom got into the habit of swearing mentally to annoy Temrash 114. He never broke the habit, and he sometimes forgets to watch his mouth while talking to children.

* ''Bubbles'', of all characters, is this way in the ''WesternAnimation/ThePowerpuffGirls'' fanfic series ''Fanfic/{{Ladder}}''. Despite being normally innocent, she curses quite a sum, especially [[spoiler:when she goes into her seizure-like states]]. It's very uncharacteristic of her so the Professor thinks it's a result of [[spoiler:brain damage caused by bringing her back to life]].

* ''Bubbles'' is this way in the ''Powerpuff Girls'' series ''Fanfic/{{Ladder}}''. The normally innocent Bubbles curses quite a sum, especially [[spoiler:when she goes into her seizure-like states]]. It's very uncharacteristic of her so the Professor thinks it's a result of [[spoiler:brain damage caused by bringing her back to life]].
