History Main / VillainousIncest

* ''ComicBook/TheTexasChainsawMassacre2007'': While it's implied throughout the franchise that the family ''may'' have been committing incest, ''Raising Cain'' outright states it. After one family member's wife is killed (in part, by him) he nonchalantly states he has plenty of other sisters he can marry, also indicating he and the rest of the family [[CrossesTheLineTwice are going to eat the dead one]] ("Meat should never go to waste!").

* In ''Manga/{{Trigun}}'', Knives's relationship with both his identical twin brother Vash and their legions of less humanoid "sisters" is not wholesome. At one point he regenerates his body by gruesomely "birthing" himself fully-formed from a sister ([[DeathByChildbirth which kills her]]), and at other points he forces Vash to use his [[WaveMotionGun Angel Arm]] in a very... suggestive way. He later tries to fuse with Vash, drawing his consciousness into himself to protect him. ''Anime/TrigunStampede'' dispenses with subtlety and overtly presents him as an abusive, controlling partner to a very unwilling Vash -- minus any sexual component, but just barely.

** The Clans in general are an antagonist faction (the setting runs on GrayAndGreyMorality with no clear heroes and very few clear villains), and because of their eugenics program and DesignerBabies using {{Artificial Womb}}s they don't have the same concepts of sexual fidelity, romance, or relations. Clan Trueborn are raised in sibkos (sibling companies) all made from the same combination of DNA from the best warriors of the previous generation. As the members of the sibko come of age, it's considered completely natural and acceptable for them to explore their biological urges with each other. This tends to disgust the people of the Inner Sphere, raised in more traditional families.

This exploits a specific primal instinct-based sex taboo and is specifically based on the equating of breaking taboos with evil. When defied, this is presented as EvenEvilHasStandards. The latter can and does come across not as a mere ValuesDissonance, but as outright {{Hypocri|te}}sy, resulting in a BrokenAesop. Many cultures have world/humanity {{Creation Myth}}s involving [[BrotherSisterIncest/{{Mythology}} divine incest]] (and human incest, if the myth involves a few early humans giving rise to all of humanity), highlighting a moral dissonance between the primal and the religious.

* ''Film/LaReineMargot'' (Queen Margot) has this in spades, with the eponymous Marguerite de Valois having sex with her brothers and their brother Anjou being in love with their mother, Catherine de Medici. The whole incestuous lot is pretty villainous with atrocities, backstabbing, and poisonings under their belt, though a couple of them are more ambiguous including Margot herself. This is a HistoricalVillainUpgrade, of course: the real Medicis had their share of intrigue and scheming but—so far as we know, anyway—no incest on this level.

** ''Literature/TheFallOfNumenor'': Ar-Pharazôn becomes the last king of Númenor by marrying the late king's daughter against her will. She's his first cousin. Pharazôn's ego and disregard for traditions simply made it that much easier for Sauron to corrupt him into Melkor-worship. Pharazôn had no legal right to the throne and marrying Míriel did not actually give it to him. He simply used it as a pretext. There are multiple versions of this. In some of JRRT's versions, Tal-Palantír's daughter is infatuated with Pharazôn (who by all accounts was likable in his youth) and marries him consensually, and hands him the ''de facto'' control of the Sceptre. In others, he takes her to himself against her will and seizes the Sceptre with the approval of the general public (who by then were mostly corrupted). This is the latest version so is probably what Tolkien eventually intended.

* Caligula with his sisters and Nero with his mother, both in ''Literature/IClaudius'' and (allegedly) in RealLife. The only reason Nero was even emperor is that his mother married the emperor Claudius—her ''uncle.'' Claudius was the first man in Roman history to marry his niece and had to change the law to permit the union. Agrippina (the niece Claudius married) was also one of Caligula's sisters, by the way. In Paul L. Maier's historical novel ''The Flames of Rome'', Nero's wife chews him out for his part in the affair, specifically pointing out that incest was apparently an old habit with her: "How old was she when her brother Caligula first seduced her, twelve!?" The Julio-Claudian dynasty in its later years was a major {{squick}}fest all around.
* In the first Literature/InspectorMcLevy novel ''The Shadow of the Serpent'', the assassin known as the Serpent is sleeping with his illegitimate daughter. However, the daughter is the one who instigated the relationship as a means of controlling her father. Needless to say, both are thoroughly screwed-up and evil people.

* Literature/MalusDarkblade comes from a BigScrewedUpFamily of sadistic, treacherous, power-hungry monsters (or just [[AlwaysChaoticEvil Dark Elves]] for short), and the incestuous relations between the siblings is the least of their misdeeds. The oldest brother openly consorts with his sister, when he's not in the high seas pillaging, youngest brother lusts for the same sister, and Malus himself shares the bed with his half-sister.

** ''Literature/TheSilmarillion'': In ''The Fall of Númenor'', Ar-Pharazôn becomes the last king of Númenor by marrying the late king's daughter against her will. She's his first cousin. Pharazôn's ego and disregard for traditions simply made it that much easier for Sauron to corrupt him into Melkor-worship. Pharazôn had no legal right to the throne and marrying Míriel did not actually give it to him. He simply used it as a pretext. There are multiple versions of this. In some of JRRT's versions, Tal-Palantír's daughter is infatuated with Pharazôn (who by all accounts was likable in his youth) and marries him consensually, and hands him the ''de facto'' control of the Sceptre. In others, he takes her to himself against her will and seizes the Sceptre with the approval of the general public (who by then were mostly corrupted). This is the latest version so is probably what Tolkien eventually intended.

* ''Fanfic/HigherLearning'': Details are not given, but in the original pre-PeggySue timeline, the first one of Shinji and Asuka's kids to demonstrate [[SurprisinglyRealisticOutcome the logical consequences]] of an AdamAndEvePlot was ''also'' the one who ended up [[SelfMadeOrphan murdering his mother.]] [[spoiler:Time-traveller Kaoru "Mizayaki" is this individual's child by his sister.]]

* In, ''Fanfic/YouAreMine'', Frollo adopts an infant Esmeralda as his daughter and names her "Agne". Agnes grows up seeing Frollo as her father, but Frollo doesn't have the same viewpoint. As she grows, he begins lusting at her. He tries to invoke WifeHusbandry and when Agnes resists he [[spoiler:rapes her]].

* In ''Film/ThatsMyBoy'' [[spoiler:Donny discovers that his son's fiancee is cheating on him… with her younger brother]].

* ''TabletopGame/{{Warhammer}}'''s Malekith, Witch King of the Dark Elves, was (in early editions) rumored to have an incestuous relationship with his mother, the Hag Sorceress Morathi. Though this has never been confirmed (and the subtext was dropped from later editions), and given that Malekith has been sealed within his magic armor for the last six and a half thousand years it is unlikely that anything too physical could have happened anyway. That being said, incest, while not ubiquitous, isn't too uncommon in Dark Elf society.

* Apedemak in ''Website/{{Lioden}}'' attempts to convince his daughter to mate with him to produce perfect children, much to her disgust and horror. While he was angry at her relationship with Apollyon earlier and had claimed to use magic, until then it was left ambiguous if he was just an over-protective father with weird beliefs or if he was genuinely a villain.

* A few ''TabletopGame/BattleTech'' examples that takes some explaining:
** Former Archon Katherine Steiner-Davion was deposed by an alliance led by her brother after she usurped the regency of her sister and cracked down on her critics in an increasingly tyrannical manner. She was remanded over to Khan Vlad Ward of [[ProudWarriorRace Clan Wolf]], a society that reproduces via DesignerBabies. Growing increasingly hostile and vengeful towards the Inner Sphere houses, including her own, she eventually ''stole her own brother's DNA to create a genetically incestuous child'' just so she could raise him to re-ignite a war between the Clans and the Inner Sphere. No, Victor had no input on this (especially considering he was murdered before he ever found out about it), and no one has any idea how she managed to acquire his DNA, either. GodSaveUsFromTheQueen.
** The Clans in general are an antagonist faction (the setting runs on GrayAndGreyMorality with no clear heroes and very few clear villains), and because of their eugenics program and DesignerBabies using {{Artificial Womb}}s they don't have the same concepts of sexual fidelity, romance, or relations. Clan Trueborn are raised in sibkos (sibling companies) all made from the same combination of DNA from the best warriors of the previous generation. As the members of the sibko come of age, it's considered completely natural and acceptable for them to explore their biological urges with each other. This tends to disgust the people of the Inner Sphere, raised in more traditional families.
** Aleksandr and Malvina Hazen are members of the same sibko, and have a relationship creepily close ''by Clan standards'', pretty much only [[UnusualEuphemism coupling]] with each other, referring to each other as "brother" and "sister" when Clan warriors tend to find familial terms repulsive, and having a playful competetive streak. Aleks is at best a KnightTemplar and PragmaticVillain, Malvina is a full-blown OmnicidalManiac.

* Antiochus and his (unnamed) daughter in Creator/WilliamShakespeare's ''The Misadventures of Pericles''. [[VillainBall For some reason]], her EngagementChallenge is a riddle whose answer is "Antiochus and his daughter are committing incest." Not a conventional Engagement Challenge, though—they're usually honored even when they're meant to be impossible, but Antiochus hasn't the slightest intention of honoring this one. The terms of the challenge mean that getting it wrong equals death, but it's made very clear that, for the sake of the king's own safety, getting it right ''[[MortonsFork also]]'' equals death. The hero of the play, Pericles, is a guy who gets it right and is being pursued by Antiochus' assassins, although later in the play, he learns that the heat is off: Antiochus and his daughter have [[StuffBlowingUp exploded]] in a display of [[DeusExMachina divine punishment]]. One of Shakespeare's weirder plays.
* Shakespeare's ''Theatre/RichardIII'' plans to secure himself on the throne by marrying his niece (the daughter of Richard's brother, King Edward IV). In the play, he has his wife killed so that he can do so, although in history she seems to have died of natural causes. Also in actual history, he was planning to marry that niece off to [[http://en.wikipedia.org/wiki/Manuel_I_of_Portugal a distant (literally) cousin]].

%%* Done by the VillainProtagonist of ''Stepmother's Sin'' during the plot, and has an ending devoted to this.
* Suggested to have happened between [[spoiler:Lord Irving and his sister]] in ''VideoGame/WildArms2'', and she wasn't exactly consenting to it, either.
* Shinji Matou of ''VisualNovel/FateStayNight'' has repeatedly raped his [[spoiler:adopted]] sister, Sakura. In one of the game's routes, this [[TheDogBitesBack comes back to haunt him in a big way]].
* The residents of Andale in ''VideoGame/Fallout3''. It [[CrapsackWorld says a lot about the world of Fallout]] that the incestuous family tree ''isn't'' the [[TownWithADarkSecret town's Dark Secret]].

* One of the major villains in ''VideoGame/FirstEncounterAssaultRecon'', Harlan Wade, plays the EvilutionaryBiologist and [[MedicalRapeAndImpregnate donates his own DNA (along with that of others) for use in impregnating his own daughter]] in hopes of producing children with powerful psychic abilities. Another villain, Aristide, calls this development 'sick'.
* Heavily implied between the {{twin|cest}}s Alexia and Alfred Ashford, antagonists of ''VideoGame/ResidentEvilCodeVeronica'', especially on Alfred's part.

* [[spoiler:Warden Darling]] in ''VideoGame/TheHouseOfTheDeadOverkill''.

* ''VideoGame/CityOfHeroes'': Tyrant and Dominatrix ({{Evil Counterpart}}s to Statesman and Ms. Liberty) had [[ParentalIncest Grandparental Incest]] behind the development team's back. It has since been {{retcon}}ned out of the story after it was pointed out. It was vaguely hinted at to be happening -- largely for {{Squick}} reasons -- back when the [[MirrorUniverse Praetorians]] were simply {{Evil Counterpart}}s to the signature heroes. Now that they're [[GreyAndGrayMorality morally ambiguous]] and important characters in their own right, it would be out of place.
* Used in ''VideoGame/AssassinsCreedII'', which repeats the [[VideoGame/AssassinsCreedI predecessor's]] habit of giving each assassination target a KickTheDog moment just to reassure you it's okay to kill them. This is one of the black marks against BigBad Rodrigo Borgia, who is implied to have a sexual relationship with his daughter. Confirmed in [[VideoGame/AssassinsCreedBrotherhood the sequel,]] with the villainy extended to his son, Cesare.
* Cesare and Lucrezia in ''VideoGame/AssassinsCreedBrotherhood''; the game even opens up with them kissing during the assault on the Assassin's compound. When Cesare is arrested for his crimes, one of them listed is incest.
* ''VideoGame/NoMoreHeroes'': At the end of the game, Travis (a very ''dark'' {{antihero}} to begin with) discovers that [[spoiler:Jeane (the FinalBoss, not his [[MoralityPet pet cat]]), the girl he's been searching for and was once romantically involved with, [[SurpriseIncest is his half-sister]]. Travis is as {{squick}}ed out as the player is. Jeane, on the other hand, doesn't seem to mind that it happened. In the end, [[DeathEqualsRedemption the two reconcile right before Travis kills Jeane]]]].
* In the InteractiveFiction story ''VideoGame/{{Anchorhead}}'' this is the dark secret of [[spoiler:your husband's family]].
* In ''[[VideoGame/RivalSchools Project Justice]]'', [[SmugSnake Kurow Kirishima]] [[AllLoveIsUnrequited one-sidedly lusts]] after his beautiful older sister [[LadyOfWar Yurika]]. Made even more obvious in the Darkside Student Council path which is from Kurow's POV [[spoiler:and in Kurow's ending, when he's seen caressing his [[BrainwashedAndCrazy brainwashed-into-subservience-to-him]] older sister's hair..]].
* It is very implied between Weiss and Nero from ''VideoGame/DirgeOfCerberus''. And at the ending [[spoiler:Nero merges with Weiss to free him from Hojo, making them become one]].
* ''VisualNovel/KaraNoShoujo'': In a variation, the overall attitude isn't that the incest is morally wrong (though there is no sexual tension with the protagonist's little sister), but rather that only the mentally unstable would do such a thing.

* [[IOwnThisTown Maven Black-Briar]] of ''VideoGame/TheElderScrollsVSkyrim'' is head of a family that includes Hemming, Ingun, and Sibbi Black-Briar. Hemming is indisputably her son. He may mention in conversation that Ingun and Sibbi are his children; Maven is listed in the Creation Kit as their grandmother. However, Maven explicitly calls Ingun her "favorite daughter", and both Ingun and Sibbi refer to her as their mother. Maven has no husband; Hemming has no wife. It's not hard to do the math, especially since both kids [[InbredAndEvil sound like Borgia expys]] - Sibbi is in prison for a murder even his mother/grandmother found unnecessarily heinous (though more from the bad publicity than the act itself), while Ingun, ''the only remotely pleasant member of the family'', is fascinated by alchemy and its more lethal applications.
* Sariss in ''VideoGame/JediKnightDarkForcesII'' was the daughter of the DarkSide cult leader [[Literature/LukeSkywalkerAndTheShadowsOfMindor Lord Cronal]], who despised her over his StrawNihilist ideology that made him see her as [[BadIsGoodAndGoodIsBad a tribute to creation rather than the destruction he idolized]]. As a result, he [[RapeAsBackstory had her raped by his fellow cult members]] and often took part in it himself, [[BeingTorturedMakesYouEvil making her almost as screwed up as he was]] and forcing [[PlayerCharacter Kyle Katarn]] to put her down.

* [[spoiler:Junko Enoshima and Mukuro Ikusaba]] of ''VisualNovel/DanganronpaTriggerHappyHavoc'' are an interesting case, as it's not even hinted at in the game they're introduced. Subtext appears in the what-if light novel ''Literature/DanganronpaTriggerHappyHavocIf''. It then becomes much more explicit in ''Anime/Danganronpa3TheEndOfHopesPeakHighSchool'', with [[spoiler:Mukuro]] being quite submissive and blushing whenever insulted by [[spoiler:Junko]], before [[spoiler:Junko]] violently pulls it out of subtext and into text by slapping [[spoiler:Mukuro]] on the butt (knocking [[spoiler:Mukuro]] to the ground) and doing un-advertiser friendly things to [[spoiler:Mukuro]] with a boot through [[spoiler:Mukuro]]'s skirt. It is not depicted as a healthy relationship at all, as [[spoiler:Junko]] [[DomesticAbuse essentially treats]] [[spoiler:Mukuro]] as a SexSlave of sorts.
* This trope shows up disturbingly often in ''VisualNovel/DanganronpaV3KillingHarmony'''s villains:
** For the most part, [[MascotVillain Monokuma]] and his [[SpinOffBabies Monokubs]] have a [[BlackComedy darkly hilarious]], if a little [[AbusiveParents abusive]] relationship. Then there's [[TheSmurfettePrinciple Monophanie]], who [[LecherousLicking licks back]] when her father is licking her and her siblings clean and later [[spoiler:gets pregnant by [[BrotherSisterIncest her brother Monotaro]]. Monotaro at least has the excuse of being a ForgetfulJones who forgot the two of them were related, but Monophanie doesn't]]. [[spoiler:She eventually suffers DeathByChildbirth when the baby turns out to be [[BigCreepyCrawlies a giant insect]] that [[ImpaledWithExtremePrejudice stabs Gonta to death]].]]
** It's revealed in the aftermath of the third trial that the murderer, [[spoiler:Korekiyo Shinguji]], had a sexual relationship with [[BrotherSisterIncest his sister]] until her untimely death. Said death drove him ''[[LoveMakesYouCrazy completely batshit insane]]'', to the point where he [[spoiler:became a SerialKiller hell-bent on sending 100 "friends" to [[IWantMyBelovedToBeHappy keep her company]] in the afterlife]]. It's implied that [[spoiler:Korekiyo]]'s sister was his LivingEmotionalCrutch, as [[spoiler:he manifests a {{Tulpa}} of her to help himself calm down when he's accused and [[VillainousBreakdown starts losing it]].]]
** It seems rather [[DownplayedTrope downplayed]] at first compared to the previous two examples, but [[CosplayOtakuGirl Tsumugi]] fantasizes about being NotBloodSiblings with [[spoiler:[[PlayerCharacter Shuichi]]]] during her [[OptionalSexualEncounter Love Suite event]]. [[TheReveal Then it's revealed]] that [[spoiler:not only is she the BigBad, but she's responsible for keeping the ImmoralRealityShow the characters are [[TrumanShowPlot trapped in]] going and helped [[FakeMemories tamper with the others' memories]]. This might imply that Korekiyo's BrotherSisterIncest was ''written into the show by her'', making it an InUniverse form of AuthorAppeal]]. [[{{Squick}} Ewww.]]

* ''Anime/PantyAndStockingWithGarterbelt'':
** Demon sisters Scanty and Kneesocks apparently enjoy partaking in strange sexual play involving [[NoodleImplements caviar, figs, and goat milk]] when the mayor isn't looking.
** But, the protagonist angel sisters are also hinted to be ''very'' close at one point (looking forward to bonding over Panty's sex tape).
* ''Anime/RevolutionaryGirlUtena'':
** [[spoiler:Akio Ohtori]] regularly has sex with [[BrotherSisterIncest his sister]] [[spoiler:Anthy Himemiya]]. [[spoiler:It's both an example of this trope, and an allusion to their nature—incest is rather common among many cultures' gods.]]
** [[spoiler:Miki and Kozue]] may do the same during their car ride, and [[spoiler:Touga and Nanami]] very nearly do; at best, it's a rather blunt metaphor about each girl's relationship with men now that they've begun puberty. Interestingly enough, [[spoiler:Nanami]], the girl who has harbored a very blatant (and often sexual) crush on her brother, is absolutely horrified when she discovers that [[spoiler:Anthy and Akio]] are intimate. And during her own car ride with her brother, she reacts with disgust and punches him away when he makes a move on her.

* Sorath and Tiriel from ''Literature/ShakuganNoShana'', stunning Shana in the process.
* The creepy twins Yu Fan and Yu Lan from ''Literature/FullMetalPanic: The Second Raid''.
* Dr. Hagen and his sister Nina in ''Anime/AgentAika''. Interestingly, she was the creepier one in that pairing.

* Played for laughs in the ''[[Manga/BlackButler Black Butler Hamlet]]'' OVA, when Grell/Ophelia gets the hots for Agni/Polonius. Agni thinks it's disgusting, even if he's not related to Grell.
* While never explicitly stated in the manga version of ''Manga/ChronoCrusade'', this is hinted at with two separate villains.
** Once Joshua gets Chrono's horns, his resulting insanity causes him to become VERY obsessed with his older sister Rosette, going so far as to tell her once they meet again that he'll destroy ''anyone'' that would separate them again. (Understandably, Rosette is horrified at this suggestion.) He also mistook his maid Fiore for his older sister when they first met, and she's later hinted to be something of a love interest for him, and even asks him to call her "sister" again before [[spoiler:they part for the last time]].
** [[spoiler:Aion]] is generally not shown to be interested in romantic relationships, he's very obsessed with [[spoiler:his twin brother, Chrono]]. He's described as "not being the same" after they parted ways by other characters, and in a flashback, he describes the sight of [[spoiler:his brother]] covered in blood as "beautiful." He also appears to be kissing the ''decapitated head of his mother'' in one scene near the end of the manga.
* The [[{{Twincest}} twins]] [[WoobieDestroyerOfWorlds Mukuro]] and [[BigBad Junko]] are heavily implied to share this in ''Anime/Danganronpa3TheEndOfHopesPeakHighSchool'' as Mukuro's sisterly affection was twisted into undying devotion as well as sexual attraction through [[ManipulativeBastard Junko's manipulation]], and the two share an incestuous MasochismTango with Junko beating, insulting, and occasionally trying to kill Mukuro while she gets off on it. In the novel tie-in ''Literature/DanganronpaZero'', Mukuro turns ecstatic and feverish as she explains Junko's motives and claims [[EntitledToHaveYou Junko needs her because she's the only one who understands her]].
* ''Anime/KillLaKill'' has Satsuki's mother Ragyo, who molests her daughter regularly. If the flashbacks are anything to go by, this has been going on for a ''long'' time. And there is the 'Bath Scene', which serves to establish Ragyo as the main villain and to show part of Satsuki's FreudianExcuse [[spoiler:and [[HeelFaceTurn shift to the protagonist side]]]]. Later in the series, [[spoiler:she does the same to her long-lost daughter, Ryuko]]. And in the same episode, we find out that Nui Harime, who is practically Ragyo's foster daughter was also molested by her (although she is the only one who doesn't seem to mind).

* Johan Liebert from ''Manga/{{Monster}}'' is one of the worst examples in this folder. Despite his twin sister trying to kill him when they were kids, he has unnatural feelings for Anna/Nina. He started stalking her, leaving her love notes, and buying gifts for her. She doesn't feel the same way, obviously, and is more than eager to shoot him again if he were to come near her—[[StrikeMeDownWithAllOfYourHatred something he seems to be banking on]].
* The behavior exhibited by Maestro Delphine from ''Anime/LastExile'' toward her younger brother Dio hints at her having incestuous feelings toward him, though this is never made explicit.
* In ''Manga/MagiLabyrinthOfMagic'', Gyokuen married her brother-in-law after her first husband died (considered incest by many ancient cultures) and once her second husband died, she became [[http://www.mangahere.co/manga/magi/v12/c147/4.html uncomfortably touchy-feely]] to her nephew/stepson first prince Kouen, to the shock and disgust of her other children. Kouha remarked that she was always very fond of Kouen and now decided to move on from her husband (Kouen's father) to Kouen himself.

* In ''Manga/TokyoGhoul'', a BreedingCult engaging in incestuous relations proves to be a major piece of the dark puzzle. Namely, [[spoiler:Rize Kamishiro is an escaped BreedingSlave that was destined to be raped and forced to bear children to her own biological father, [[HunterOfMonsters CCG]] chairman Tsuneyoshi Washuu. Her half-brother, Furuta, turns out to be a {{Yandere}} that wants to replace their father, marry her, and use her as his personal BabyFactory]].
* Downplayed in ''Anime/MagicalGirlLyricalNanohaStrikers'' where [[MadScientist Jail Scaglietti]] [[CloningGambit implanted his twelve cyborg daughters with clones of himself]]. No actual sexual intercourse took place, though it doesn't make it any less creepy.
* In ''Manga/{{Trigun}}'', Knives's relationship with both his identical twin brother Vash and their legions of less humanoid "sisters" is not wholesome. At one point he regenerates his body by gruesomely "birthing" himself fully-formed from a sister ([[DeathByChildbirth which kills her]]), and at other points he forces Vash to use his [[WaveMotionGun Angel Arm]] in a very... suggestive way. He later tries to fuse with Vash, drawing his consciousness into himself to protect him. ''Anime/TrigunStampede'' dispenses with subtlety and overtly presents him as an abusive, controlling partner to a very unwilling Vash -- minus any sexual component, but just barely.

* ''Fanfic/InnerDemons'': You know the subtle IncestSubtext that exists between [[WesternAnimation/MyLittlePonyFriendshipIsMagic Twilight Sparkle and Shining Armor]] in canon? Well, after being consumed by her [[EnemyWithin Queen persona]], Twilight stops bothering with either subtlety ''or'' subtext, to the point that she [[spoiler:imprisons and impersonates Cadence to sleep with Shining Armor]]. And when Shining Armor rejects her advances and sides with the protagonists, Twilight has a full-blown VillainousBreakdown and attempts to [[MurderTheHypotenuse kill Cadence]] in a jealous rage.
* In the ''Fanfic/OneiroiSeries'', a ''[[Webcomic/TheOrderOfTheStick Order of the Stick]]'' series of fanfics, [[SplitPersonalityTakeover Deirdre]] [[spoiler:[[MoralEventHorizon rapes and kills her father, gets pregnant by him, and then manipulates her brother into having sex]]. Most of the other villains think that she's going to do the same to her uncle, too]].
* In ''[[http://percyjacksonfanfiction.wikia.com/wiki/Stand_In_The_Rain Stand In The Rain,]]'' a ''Literature/PercyJacksonAndTheOlympians'' fanfiction, [[spoiler:the main character is raped by her mentally disturbed half-brother]]. FromBadToWorse: [[spoiler:she gets [[ChildByRape pregnant]]]].
* There is a ''VideoGame/PokemonDiamondAndPearl'' CrackFic in which Saturn and Jupiter have sex regularly even though they're [[KissingCousins cousins]]. Mars also mentions having once had sex with her ''brother,'' which she thinks of as okay because the ancient Egyptians used to do it. Granted, none of them actually do anything all that evil, except under Cyrus's orders.
* ''Fanfic/TheImmortalGame'': [[BigBad Titan]], having taken over Equestria, attempts to force his daughter Luna to marry her brother Empyrean to solidify the latter's position as rightful acting ruler. [[spoiler:It's also later revealed that his wife Terra is actually his daughter as well.]]
* Given the fact that most ''Series/WizardsOfWaverlyPlace'' fics are focusing on [[BrotherSisterIncest Justin/Alex]], many of them portray their relationship as wicked and harmful, and few have {{happy ending}}s.
** In ''[[http://www.fanfiction.net/s/6431324/1/Perfect_Lies Perfect Lies]]'', Justin has a calm life, a four years old daughter, and a loving wife. Then Alex comes and creeps in, destroying it slowly, by alluring him into having sexual affairs with her. And [[EvilTastesGood she enjoys it]].
* Rather a lot of ''Literature/HarryPotter'' fanfiction, and for good reason. As noted below, the purebloods are absolutely obsessed with keeping their lineage "pure", untainted by {{Muggle|s}} blood. There's also not that ''many'' of them, so sooner or later they're going to have to resort to [[KissingCousins first cousins]], or [[BrotherSisterIncest worse]]. And some of Voldemort's followers are easily bugfuck nuts enough that they might actually be okay with this!

* Much ''Anime/CodeGeass'' fanfic, especially [[AlternateUniverse AUs]] where Nunally and Lelouch are never banished, take the [[MemeticMutation Britannincest]] subtext to the next level. Schneizel/Cornelia, Cornelia/Euphemia, Euphemia/Lelouch, Lelouch/Nunally, and Schneizel/Lelouch are all very popular.

* ''Fanfic/HigherLearning'': Details are not given, but in the original pre-PeggySue timeline, the first one of Shinji and Asuka's kids to demonstrate [[SurprisinglyRealisticOutcome the logical consequences]] of an AdamAndEvePlot was ''also'' the one who ended up [[SelfMadeOrphan murdering his mother.]] [[spoiler:Time-traveller Kaoru "Mizayaki" is this individual's child by his sister.]]

* In the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' parody series ''WebVideo/FriendshipIsWitchcraft'', [[spoiler:VillainProtagonist Twilight Sparkle]] cements her place as the BigBad of the series by sabotaging her brother's wedding, imprisoning his fiancee in a cave and leaving her to die, and [[spoiler:marrying her brother herself.]] She tries to justify her crush [[spoiler:and marriage]] to her brother by saying they are NotBloodSiblings. It's still pretty creepy [[EvenEvilHasStandards even according to Fluttershy]]. And before anyone asks, by all appearances her brother has been brainwashed into going along with it.
* A ''Film/{{Descendants}}'' fanfic series features [[WesternAnimation/{{Cinderella}} Anastasia's daughter and Drizella's son]] as a couple and they're among the numerous [=VKs=] that help our main characters take over Auradon.

* The ''WesternAnimation/{{Gargoyles}}'' series "[[http://fanfic.gargoyles-fans.org/author.php?author=tribun&sortorder=desc Broken Mirror]]" includes the revelation that Thailog [[spoiler:created a clone of Angela, Alegna, in secret along with the other clones. Brooklyn is disgusted when he runs into Alegna on a patrol and learns how Thailog has manipulated her into a relationship with him through talk of keeping the bloodlines "pure", even though Thailog is technically Alegna's father since he's both her creator and his genetic template (Goliath) directly fathered Alegna's template (Angela)]].
* While the relationship between Papa Smurf and Smurfette in the ''Fanfic/EmpathTheLuckiestSmurf'' story series is mostly father and daughter with only a hint of incestuous desire from Papa Smurf himself, even though neither of them is biologically related, their MirrorUniverse counterparts go straight into this territory by its Papa Smurf marrying its Smurfette outright, although its Smurfette is not entirely faithful unto him and has promiscuous desires for her fellow Smurfs, except for its Empath, who is basically a [[MindRape mind rapist]].
* A play in ''Fanfic/PerfectDiamondWorld'' uses characters obviously based on Queen Elsa and her sister Princess Anna. The play portrays them as a villainous couple. Most viewers take it as political slander, but Elsa and Anna's cousin Rapunzel realizes the truth in the play. Elsa and Anna may not be evil, but they ''are'' in a relationship, and it disgusts Rapunzel.
* ''Fanfic/SoWedBothBeFree'': On top of being [[AbusiveParents emotionally abusive]] towards his Azula, Ozai also wishes to [[RoyalInbreeding continue his bloodline]] using his [[ParentalIncest teenage daughter]]. He [[ChildByRape succeeds in getting her pregnant]] after a few years of trying. When Azula gets [[LivingEmotionalCrutch too close]] to her slave (and girlfriend) Ty Lee for his liking, Ozai reveals his intentions to sell Ty Lee to someone else. This prompts Ty Lee to [[TogetherInDeath attempt lover's suicide]] with Azula (however [[DrivenToSuicide only Ty Lee dies]]). Years later, Ozai ends up dying of illness, and he [[DeliriousMisidentification mistakes]] Azula for her MissingMom Ursa.
* In ''Fanfic/ThingsJadeHates'', Jade's abusive mother sexually abused her in the past. She spent time in jail but has recently been let out. She threatens to do the same to Jade's 6-year old brother Ash.
* In ''Fanfic/AshAndPetals'', Azula's abusive father Ozai has sexually abused her for years. After being [[TheExile exiled]], Azula finds out she's [[ChildByRape pregnant by him]].

[[folder:Film]]

* In ''Film/CryOfTheBanshee'', Edgar Whitman's oldest son, Sean, rapes his stepmother Lady Patricia.

* ''Series/TheXFiles'' episode "[[https://tvtropes.org/pmwiki/pmwiki.php/Recap/TheXFilesS04E02Home Home]]", about an InbredAndEvil family of {{serial killer}}s.

* Creator/MercedesLackey uses this trope regularly, often but not always in extrememely nonconsensual contexts.

*** Much of the plot of ''Oathbreakers'' has Tarma and Kethry trying to find the wherabouts of Idalia, a princess who renounced her place in succession. [[spoiler:Her brother, on being crowned king, decided to keep her from interfering and imprisoned and raped her. She killed herself.]] The rest of the book is dedicated to {{Revenge}}.

* ''Literature/VorkosiganSaga'': In the backstory of ''A Civil Campaign'', Richars attempts this on a 12-year-old Lady Donna. She managed to fight him off, so he drowned her puppy in retaliation. Nobody believed her, and this among many other similar crimes is why she's determined not to allow him to inherit the distract.

* The accusation of incest with their mother has been levelled against many Roman emperors, but the primary source for this is ''Twelve Caesars'' by Suetonious, a writer who in some circles is thought of as a gossip columnist rather than a historian. It has been pointed out that Suetonious was not above spicing up a scroll on a safely-dead Emperor with embellished details, partly for the money and partly at the political behest of new rulers looking to discredit the old. Therefore a case can be made for at least some of the incest alligations to be treated as fabuluous or just made up, however sociopathic that ewmperor might otherwise have been.

** The Clans in general are an antagonist faction (the setting runs on GrayAndGreyMorality with no clear heroes and very few clear villains), and because of their eugenics program and DesignerBabies using {{Artificial Womb}}s they don't have the same concepts of sexual fidelity, romance, or relations. Clan Trueborn are raised in sibkos (sibling companies) all made from the same combination of DNA from the best warriors of the previous generation. As the members of the sibko come of age, it's considered compeletely natural and acceptable for them to explore their biological urges with each other. This tends to disgust the people of the Inner Sphere, raised in more traditional families.

* Parodied in ''Film/NotAnotherTeenMovie'' where the interest is reversed with the sister agreeing to help him win the bet to get the nerdy girl only if he'll agree to have sex with her after he wins. He objects that they are related and she responds "—only by blood!"

* Andrea and Andreas Strucker, the Fenris twins of Creator/MarvelComics, derived their power from being in constant physical contact with each other. And then it got {{squick}}ier after Andrea died. Technically their incest was never confirmed, and Andreas denied it at one point (well, that's not surprising). But the implications are incredibly strong.
* Baron Mordo, the archenemy of ComicBook/DoctorStrange, knowingly had a sexual relationship with his Romani half-niece (she was unaware of the relationship) which ultimately resulted in a daughter. Just to make it worse, Mordo seduced her to steal the Book of Cagliostro, a book of spells, and then abandoned her.
* While it was implied throughout the franchise that the family ''may'' have been committing incest, the comic ''Film/TheTexasChainsawMassacre: Raising Cain'' outright stated it. After one family member's wife is killed (in part, by him) he nonchalantly states he has plenty of other sisters he can marry, also indicating he and the rest of the family [[CrossesTheLineTwice are going to eat the dead one]] ("Meat should never go to waste!")
* Quicksilver and Scarlet Witch are in a long-term relationship with each other in the ComicBook/UltimateMarvel universe, possibly based on an earlier {{meme|ticMutation}} originating in the original comic universe. So much so to the point where Pietro actually gets jealous when Wanda hits on a robot. Although the two of them are more AntiHero with AntiVillain moments as opposed to out and out villains.
* In Creator/AlanMoore's ''ComicBook/SwampThing'', Abby is unknowingly seduced by her own uncle, the uber-evil villain Dr. Anton Arcane.
* ''ComicBook/StrangersInParadise'' has Darcy and, yes, [[spoiler:David]].
* ''Many'' of the villains in ''ComicBook/SandmanMysteryTheatre'' are incestuous in one way or another, to the point where you start to wonder about the writer…
* In the BadFuture of ComicBook/{{Wolverine}}'s "ComicBook/OldManLogan" arc, [[Characters/IncredibleHulkBruceBanner Bruce Banner]] has made a FaceHeelTurn and sired the Hulk Gang with his cousin Comicbook/SheHulk.
** To add to the villainy part, it's strongly implied that this was non-consensual.
* The ''Comicbook/SinCity'' short story entitled ''Daddy's Little Girl'' has a rather disturbing example of this. [[spoiler:A woman seduces a man but claims that her father does not approve of the relationship, eventually asking him to shoot him. It turns out that the whole thing was a setup. She was sleeping with her father and him apparently [[NightmareFetishist gets off by killing people before sleeping with his own daughter]].]]
* The gods are naturally featured in ''ComicBook/WonderWoman''. Mentioned in their habit of boinking their blood relatives.
* Franchise/TheFlash villain Ragdoll (Peter Merkel) is heavily implied to have sexually abused his daughter, Alex. Later on, it appears that his son Peter Jr. and Alex (both now villains themselves) partake in an incestuous relationship themselves, although a consensual one.
* In the ''ComicBook/SpiderManBlackCatTheEvilThatMenDo'' miniseries, Francis Klum outright states that his big brother Garrett sexually abused him for years, to the point where Francis became unable to enjoy consensual sex, which led to his discovering his mind-control abilities.
* In ''ComicBook/{{Runaways}}'', it's never been outright stated that Molly's evil parents were an incestuous couple, but they ''do'' happen to have the same powers and their mutations manifested in the same way, which is, if not impossible, extremely rare with mutants who are not biologically related. The 2017 series revealed that they were foster siblings that got their powers through experimentation by Alice's mother, at least according to said mother.
* Jason and Cheryl from ''ComicBook/AfterlifeWithArchie'' are involved in {{twincest}}. It's implied to not be 100% consensual on Cheryl's side. As a child, Jason was very clingy towards Cheryl to the point of [[spoiler:killing her puppy in jealousy]]. As a teenager, he is very overprotective of her and gets jealous very easily.
* ''ComicBook/{{Vampirella}}'': After Pixie Fattonie is turned into a vampire, one of the first things she does to show how [[TranshumanTreachery she's lost all humanity]] is to molest her sister Dixie in front of a crowd of vampires.

* ''VideoGame/BlazBlue'':

* Common in the Literature/AlexDelaware novels by Creator/JonathanKellerman.
* ''Literature/AndTheAssSawTheAngel'' had an [[CannibalClan incestuous clan]] of {{serial killer}}s living up in the hills. The protagonist's father was a defector from this clan.

* The Bathory siblings in the ''{{Literature/Bloodline|2006}}'' series are shown to be sexually involved- owing perhaps to their ImmortalityImmorality.

* In ''Literature/{{The Crying of Lot 49}}'', the characters go to see a Jacobean-era revenge play called ''The Courier's Tragedy'', whose villains are an incestuous family of aristocrats vying for the throne.
* Creator/RobinMcKinley's ''Literature/{{Deerskin}}'' is built on this trope, being based on the classic fairy tale "Donkeyskin". When the king's wife dies, he promises to only marry someone as beautiful as she. Should have included a "kin excluded" clause. The rest is nothing short of mortifying.

* [[BigBad Lord Raith]] of the [[OurVampiresAreDifferent White Court]] in ''Literature/TheDresdenFiles'' has the habit of ''raping'' his daughters into [[MoreThanMindControl submission]], thus amplifying the evil of this trope by making it non-consensual. He kills his sons for being potential "threats," though, even though this cuts his potential workforce in half and the canonical fact that the [[LesbianVampire Raiths tend not to care about gender]] when it comes to food. [[spoiler:Maybe he decided to make the extra sexual slaves would have been too much of a drain since he'd been cursed to be unable to feed and thus die a slow death via starvation. In the end, it doesn't matter, since it's one of his "not a threat" daughters that [[MindRape turns him into a vegetable]].]]
** Thomas says that his father's tastes "don't run that way", and there are a few other times when it's implied that the Raiths do have gender preferences when it comes to feeding, even if they're physically capable of going both ways
** The same daughter that turned the tables on Lord Raith, Lara, later [[spoiler:rapes her cousin Madeline to death while continuously ripping out her innards.]]
** Nicodemus and his daughter Deirdre have been lovers for thousands of years. She talks about it in more detail in ''Skin Game'', where she claims that their relationship started completely platonic, and it was only when both of them had been working together as partners for several centuries that they started to see each other as equal lovers instead of father and daughter. Harry, while still disgusted, finds it difficult to refute her assertion that their relationship is much deeper and stronger than any of the conventional romances he's had, and it serves as a strangely humanizing moment for two unrepentant villains. Of course, this makes [[spoiler:their mutual willingness for Nicodemus to kill her to accomplish his goals all the more shocking, and even after this final leap over the MoralEventHorizon, Harry provoking him with his memories of her is enough to break his usual self-control]].
* In ''Literature/{{Dune}}'', Baron Vladimir Harkonnen openly ogles his nephew Feyd-Rautha (which both the 1984 [[Film/Dune1984 movie]] and 2000 [[Series/{{Dune}} miniseries]] played up for all its worth) and he also harbors an attraction to Paul Atreides ([[spoiler:who, it turns out, is his grandson]]). The ''Literature/DuneEncyclopedia'' suggests that the Baron and Feyd had a sexual relationship, and strongly implies that he had sex with his mother before strangling her.

* In ''[[Literature/TheElricSaga Elric of Melniboné]]'', TheEvilPrince Yyrkoon is described as "openly lusting after his sister Cymoril." Apparently, it's {{justified|Trope}} (among other things) by norms that allow incestuous royal marriages, but even the decadent Melniboneans feel it's slightly wrong for Yyrkoon to look forward to marrying his sister. Cymoril is also a {{Love Interest|s}} for Elric, and though Elric and Cymoril are [[KissingCousins cousins]], this is not presented as wrong.

* The "novelization" of the 1980 ''Film/{{Flash Gordon|1980}}'' included a small scene of Ming and Aura pleasurably reminiscing about the most recent time they had (BDSM-heavy) sex together… eeeeeep.

* Mason Verger in the book but not TheFilmOfTheBook ''[[Literature/TheSilenceOfTheLambs Hannibal]]''.

* ''VideoGame/BlazBlue'' resident {{jerkass}} Jin Kisaragi has so much creepy HoYay subtext with his brother, Ragna The Bloodedge that it strains the limits of a T-rated game. And if that's not enough, his theme music is titled "Lust Sin."
** This is made fun of a lot in the games' story mode.
** And then in Ragna's ending, [[spoiler:there's v-13, a clone of his sister, penetrating him with a sword with all sorts of suggestive dialogue.]]
* One of the major villains in ''[[VideoGame/FirstEncounterAssaultRecon F.E.A.R.]]'', Harlan Wade, plays the EvilutionaryBiologist and donates his own DNA (along with that of others) for use in impregnating his own daughter in hopes of producing children with powerful psychic abilities. Another villain, Aristide, calls this development 'sick'.

* ''VideoGame/CityOfHeroes'': Tyrant and Dominatrix ({{Evil Counterpart}}s to Statesman and Ms. Liberty) had [[ParentalIncest Grandparental Incest]] behind the development team's back. It has since been {{Ret Con}}ned out of the story after it was pointed out.
** It was vaguely hinted at to be happening—largely for {{Squick}} reasons—back when the [[MirrorUniverse Praetorians]] were simply {{Evil Counterpart}}s to the signature heroes. Now that they're [[GreyAndGrayMorality morally ambiguous]] and important characters in their own right, it would be out of place.

* ''VideoGame/NoMoreHeroes'': At the end of the game, Travis (a very ''dark'' {{antihero}} to begin with) discovers that [[spoiler:Jeane (the FinalBoss, not his [[MoralityPet pet cat]]), the girl he's been searching for and was once romantically involved with is [[BrotherSisterIncest his half-sister]]. Travis is as {{squick}}ed out as the player is. Jeane, on the other hand, doesn't seem to mind that it happened. In the end, [[DeathEqualsRedemption the two reconcile right before Travis kills Jeane]]]].

* ''VisualNovel/KaraNoShoujo.'' The overall attitude isn't that the incest is inherently wrong (though there is no sexual tension with the protagonist's little sister) but that only the mentally unstable would do such a thing.
* Once you learn the backstory, ''VideoGame/HauntingGround'' becomes MADE of this. Basically, [[spoiler:more or less every one of Fiona's stalkers is closely related to her, except Daniella. Her family's been cloning themselves through UsefulNotes/{{alchemy}} for centuries, each generation being composed of identical copies of the alchemist Aureolus Belli, Fiona being the first naturally born, non-Aureolus-clone Belli in hundreds of years. Her father was one of these clones, and his "brother" Riccardo stalks Fiona in an [[AttemptedRape attempt]] to [[StalkerWithATestTube impregnate her with another clone]]. Again, Riccardo is, not counting his rapid degeneration due to being hastily made, completely identical to Fiona's [[ParentalIncest father]], even if he wasn't already her [[CreepyUncle uncle]]. Debilitas, the first stalker in the game, is another clone, this time made by Riccardo. It's not immediately obvious though since Debilitas's creation was even more botched than Riccardo's own, though Debilitas does not yet seem to be suffering from any degeneration. This might not completely count as Debilitas's attraction to Fiona is entirely innocent and his danger to her is unintentional, but still. Lorenzo, on the other hand, swings right back into this trope. He is Fiona's "grandfather" and, again due to the cloning, is also genetically her father, the same as Riccardo. Like Riccardo, he wants Fiona's body, but for the Azoth contained inside rather than purely out of lust. Though, given some of the comments he makes towards her, especially after he's regressed in age to a young man, and the tone of voice he uses when talking to her, he's probably got some fairly squicky plans for her other than just Azoth-extraction]].

** In the backstory of [[http://www.scp-wiki.net/scp-3288 SCP-3288,]] Leopold I of the Holy Roman Empire was taught by a [[ReligionOfEvil Sarkicist priestess]] on how to [[RoyallyScrewedUp save his family]] ([[BlueBlood the Habsburgs]]) from [[RoyalInbreeding their inbreeding]] (along with some of her [[LovecraftianSuperpower magic]]). However, the priestess in question [[EvenEvilHasStandards eventually became disgusted with Leopold]] when he started to [[KickTheDog experiment on commoners]] and [[YouHaveOutlivedYourUsefulness kill his own staff to cover his tracks]], with her even demanding him to [[AbdicateTheThrone give up his crown]] and hand over his possessions to the common people. It [[BurnTheWitch didn't end well for her]], and he continued his experiments which led to the SCP in question; a [[MonstrousCannibalism cannibalistic]] HumanoidAbomination subspecies of man descended from him [[SuperpowerfulGenetics that becomes stronger with each generation through incest]].

* Eleanor Prentiss Shaw of ''Film/TheManchurianCandidate'' (known in the novel as Eleanor Iselin). Both film versions show Eleanor coming on to her son Raymond, whose consent is dubious given his brainwashing, and the novel on which it was all based includes frank mentions of [[spoiler:consummated incest, both between Eleanor and her father Tyler and between Eleanor and Raymond]]. Eleanor figures as a villain in both the novel and the original film version. In the remake, she's a likable character who does horrible things with good intentions, and in all three works, the incestuous element is definitely used to enhance her creepiness.

* In ''Manga/{{Trigun}}'', Knives's relationship with both his identical twin brother Vash and their legions of less humanoid "sisters" is not wholesome. At one point he regenerates his body by "birthing" himself from a sister (which kills her), and at another he forces Vash to use his Angel Arm in a very... suggestive way. He later tries to fuse with Vash, drawing his consciousness into himself to protect him. ''Anime/TrigunStampede'' dispenses with subtlety and overtly presents him as an abusive, controlling partner to a very unwilling Vash -- minus any sexual component, but just barely.
