[[caption-width-right:250: One of the most infamous examples of incestuous ShipMates in the history of literature.]]

When a pair ([[OneTrueThreesome or more]]) of characters who are given the {{Shipping}} treatment are related to each other.

Incest is a serious taboo among human beings--most cultures have an incest taboo.[[note]]While some definitions of incest may be relative (cousins count in some cultures but not in others), sex between siblings or parent/child is almost universally abhorrent.[[/note]] Despite this, [[ForbiddenFruit or perhaps because of it]], there is a significant amount of people interested in it, [[RuleThirtyFour and this being]] [[TheInternetIsForPorn the Internet]], they can't wait to share their {{shipping}} theories with you.

Even with the taboo, they might have an easier job than the HoYay {{Shipp|ing}}ers, since normal family members are often so close to each other, both physically and emotionally, that with any other partner it can easily be interpreted as romantic and/or sexual. Just pick up any dialogue between relatives, [[SelectiveObliviousness ignore the intended meaning]], and Ta-da! you have subtext. There's also a good chance that you have [[NoYay repelled, or otherwise alienated a good part of the fandom]] -- but if the fandom is big enough, there's a chance you'll find like-minded company anyway.

This is a subpage for fandom theories. When the same effect is featured in the work in question that is actual IncestSubtext. See also HoYay and FoeYayShipping for other shipping tropes that are based on fan-speculation, and IncestIsRelative page for a collection of other incest-related tropes.


[[folder:Anime & Manga]]
* The anime for ''Manga/DotHackLegendOfTheTwilight'' was notorious for this to the point that it's what a lot of non-fans of the series in general tend to remember about it. The manga it was based on, on the other hand, was vague about it at best.
* ''Manga/AngelSanctuary'' could not be more blatant about Setsuna and Sara, but some see this between Rociel and Alexiel as well.
* ''Manga/AxisPowersHetalia'':
** The very ship-happy fandom naturally has much of this. Switzerland and Liechtenstein, Russia and Belarus (though that one's canon [[{{Yandere}} on Belarus' side]]), China and Korea, etc.
** [[IdiosyncraticShipNaming Germancest]] (Germany/Prussia) is a really popular pair, even more popular than canon or plausible couples like Prussia/Hungary, Austria/Hungary or Finland/Sweden. Prussia's behavior around Germany is borderline on flirting, but this is quite normal anyway, because it's ''[[MemeticMolester Prussia]]''.
** The NotBloodSiblings cases, like Canada and America, or China and Japan. Though Canada and America look so much alike, it seems to some of the fandom like a case of {{twincest}} or even ScrewYourself.
** Norway and Iceland shipping ''increased'' somewhat after the revelation of their connection came out because it attracted shippers who liked the "forbidden" appeal.
** Many fanfics featuring England's brothers (namely Scotland, Ireland, Wales and sometimes Northern Ireland) really love to play up the sibling rivalry setup for all the FoeYay it is worth.
** Veneziano Italy and Romano Italy are, in fact, half-brothers, similar to the situation with Norway and Iceland. Naturally, following along the Germancest lines (or perhaps predating it), together they're called Itacest.
* Ichigo / [[spoiler:Uryuu]] is a relatively common ''Manga/{{Bleach}}'' {{Yaoi}} pairing. Later chapters of the manga revealed that [[spoiler:Uryuu's father and Ichigo's mother were first cousins, making the boys second cousins]], so this is also a case of SurpriseIncest. The revelations have not much-dampened enthusiasm for the ship. [[spoiler:Ryuuken and Masaki had a failed ArrangedMarriage in canon, so clearly the cousin thing isn't an insurmountable barrier. While very much a minority pairing as it contradicts canon 'ships, there's also some fandom for Ryuuken/Masaki as well.]]
* ''Anime/CodeGeass'': It's just all over the place in that show, it even has its own BrotherSisterIncest page. Lelouch/Nunnally, Lelouch/Euphemia (which is actually canon on Lelouch's side), and Cornelia/Euphemia are three of the most prominent examples.
* ''Manga/DGrayMan'' has Komui and Lenalee Lee. Komui's rather intense sister complex does nothing to disprove this.
* From ''Anime/DragonBallZ'' there are some people who ship opposite-sex twins Androids 17 and 18 together. Also, there are the pairings of "Son-cest" (various incestuous pairings within Goku's family) and Vegeta/Trunks or Vegeta/Future Trunks. There's not a lot of it but Vegeta/Bra exists too.
* Agon and Unsui of ''Manga/{{Eyeshield 21}}'' is THE incest pairing of the fandom. It's not all that hard to see why, Agon is (without a doubt) the most important person in Unsui's life and Agon's a sociopathic playboy and {{memetic molester}} whose feelings for his brother are left ambiguous.
* The three most popular pairings for Gou from ''Anime/{{Free}}'' are apparently her and Makoto, her and Haru, and her with her brother Rin. It doesn't help that Gou ''does'' admire his muscles in one scene similarly to how she gawks at other boys.
* ''Manga/FullmetalAlchemist'':
** Brothers Edward and Alphonse are one of the most popular shipping targets in the fandom, with the [[Anime/FullmetalAlchemist 2003 anime]] infamous for showing how close the brothers really are. A common saying amongst fans of the relationship is that "they broke so many taboos already, what's one more?"
** A case of SurpriseIncest happened in the 2003 anime. [[spoiler:Edward]] and [[spoiler:Envy]] are a popular pair due to the FoeYay between them however near the tail end of the series there's a twist: [[spoiler:Envy is Ed's half-brother]]. Instead of abandoning ship, a lot of fans only saw this as making the pairing more interesting.
* [[BrotherSisterIncest The Nishizumi sisters]], [[TheHero Miho]] and [[ByronicHero Maho]] from ''Anime/GirlsUndPanzer'' are a surprisingly popular pairing among the fandom, since there are no male characters who are the girls' ages, and relatively little LesYay. This is only reinforced by the revelation in ''Little Army'' that Maho [[spoiler:in contrast to her initial impression as an AloofBigSister, loves Miho enough to live up to being Nishizumi heiress so that Miho will not have to]].
* Admittedly the cast is small but the most popular ''Manga/NoMatterHowILookAtItItsYouGuysFaultImNotPopular'' ship is Tomoko and her brother Tomoki. Tomoki used to adore his sisters years ago but is now embarrassed by the fact he wanted to marry her as a little kid.
* ''Anime/KillLaKill'' has [[spoiler:Ryuko/Satsuki]]. They were already a pretty popular ship because of the FoeYay, but then they were revealed to [[spoiler:be sisters]] and then it skyrocketed. To add even more fuel to the fire, the ending has the two [[spoiler:[[ItMakesSenseInContext embracing while naked.]]]]
* ''LightNovel/MariaSamaGaMiteru'' has Rei and Yoshino, who are canonically ''soeurs''. The ''soeur'' relationship ranges anywhere from a RomanticTwoGirlFriendship to [[HomoeroticSubtext ambiguously romantic]]. Many people ship the two without even realizing that they're cousins.
* Kido, Seto, and Kano from ''Anime/MekakucityActors'' are NotBloodSiblings but make it clear that [[HappilyAdopted they're siblings]]. It doesn't stop fans from shipping them.
* ''Manga/{{Naruto}}'':
** The number of Itachi/Sasuke fans would surprise newbies, and the size of the fandom only seemed to ''increase'' when [[spoiler:Itachi died and Sasuke learned that Itachi had done everything -- including killing the rest of his family -- for Sasuke's sake]].
** [[KissingCousins Neji/Hinata]] is the second most popular incest pairing, though it bears mention that Japan has less of a taboo regarding relationships between cousins than Western nations do.
** Naruto and [[spoiler:Karin]] were a crack-ship with a few fans for most of the series, but it got a boost in the fandom when it was revealed that [[spoiler:Karin]] is an Uzumaki. Their direct relationship is never clarified; however, fans streamline them into KissingCousins.
** Naruto with both his mother Kushina and his father Minato are also popular incestous pairings, mainly because the parents look so [[AbsurdlyYouthfulParents young and pretty]] they actually look more like Naruto's ''siblings''.
** In {{canon}}, it's never clarified if Hinata's parents or Sasuke's parents were related. Most fans depict them as either distant relatives or outright cousins, due to the StrongFamilyResemblance between them.
** ''Manga/{{Boruto}}'' has been shipped with most members of his family, including his father Naruto, mother [[spoiler:Hinata]], sister Himawari, and aunt [[spoiler:Hanabi]].
* The brothers Ace and Luffy are a fairly popular pairing in the ''Manga/OnePiece'' fandom. And since the flashbacks to their childhood there is also now [[spoiler:Sabo]]/Luffy, Ace/[[spoiler:Sabo]], and [[spoiler:Sabo]]/Luffy/Ace {{OT3}} shipping. In a looser definition, Ace is also often shipped with his crew mate Marco, who is as much of a brother to him as Luffy is.
** As of the Whole Cake Island Arc, Sanji was revealed to [[spoiler:have three brothers and an older sister.]] Shipping abounds.
* ''LightNovel/{{Oreimo}}'' is built on this, with a fanbase largely formed of people who want to see Kousuke and Kirino together. [[spoiler:They do in the end.]]
* Most of ''Anime/OsomatsuSan'' shipping consists of pairing any number of Matsuno sextuplets together.
* Hikaru and Kaoru Hitatchiin from ''Manga/OuranHighSchoolHostClub'' make this easy, deliberately playing up the {{Twincest}} angle for the benefit of their fans. Their actual relationship is left ambiguous, but real life fans love it as much as the fictional ones.
* ''Manga/PandoraHearts'': Gil's younger brother, Vincent, is [[{{Yandere}} extremely possessive]] of him.
* ''Anime/PantyAndStockingWithGarterbelt'' has plenty of fans that ship the title sisters together. Their evil counterparts, Scanty and Kneesocks, also have this going, though in their case it's also canon.
* In ''Manga/PeacemakerKurogane'', Tatsunosuke's overprotectiveness over his younger brother Tetsunosuke sometimes causes this.
* ''{{Manga/Saki}}'' and Teru Miyanaga sometimes get paired despite canonically not being on good terms, as Teru is unwilling to speak with Saki. Some shippers take Teru's [[IHaveNoSon denying having a sister]] to mean that Teru is ''in love with'' Saki.
* ''Manga/SgtFrog'' has Giroro and his elder brother Garuru which is the most popular Giroro-oriented ship aside from Gironatsu and Girokuru for the Japanese fandom especially. This is most likely due to the lengths Garuru goes to ensure Giroro remains on his mission as well as Giroro's admiration for him/frantic, embarrassed reactions when he's near. The Hinata family is shipped together sometimes as well.
* ''Manga/SketDance'': Bossun/[[spoiler:Tsubaki]] is rather well-known inside the fandom after TheReveal that they are twins.
* ''Anime/TengenToppaGurrenLagann'' fandom has not insignificant sect of Simon/Kamina shippers, who call each other their brother. While it's a little ambiguous whether the characters actually are related, they're certainly close enough that it probably doesn't matter.
* In ''Manga/{{Touch}}'', Yuka Nitta is, at least at first, very protective of her older brother and a bit too concerned at the prospect of him having a love life.
* ''LightNovel/ReZero'' contains one of the biggest examples of this pairing as an example twin-sisters Ram and Rem. So much so that they are the fan artists' FanPreferredCouple over Rem/Subaru. RomanticTwoGirlFriendship more or less obvious status of their relationship, presence in it of the most popular heroine of the year 2016 and including easy supported by the official art, only plays for the benefit of the rising popularity of such shipping. Moreover, due to some chemistry between Subaru and Ram in the first half of the second arc, many artists seem to like the idea of ​​a [[OneTrueThreesome romantic relationship between him and the two twins]].
* In ''Manga/ToLoveRu'' many fans love pairing Mikan and Rito. Even Momo In-Universe would include Mikan in The Harem Plan.
* ''Manga/VampireKnight'' had Zero and Ichiru. And the [[spoiler:Kuran]] family has a history of incest, as seen in the current generation between [[spoiler:Kaname and Yuuki.]] Many people do ship them.

* In 2009, Folgers debuted a holiday commercial about two siblings reuniting at home on Christmas morning over a cup of coffee. The brother returns home from a volunteer trip to West Africa, and surprises his sister with a gift. She peels off the bow and places it on her brother's chest, declaring, "You're my present this year." It's saccharine, and overflowing with IncestSubtext. Since then, it has spawned a small, bizarre fandom known as Folgerscest. [=AO3=] even has a tag for them: ''Folgers "Home for the Holidays" Commercial''. It's all parody, ranging from {{affectionate|Parody}} to absurdest.

[[folder:Comic Books]]
* ''Franchise/TeenageMutantNinjaTurtles'':
** Leonardo and Raphael fight in such a way half the time that it comes off more like BelligerentSexualTension than actual SiblingRivalry. This is especially noticeable in the 2007 film.
** All four Turtles get paired up with each other. You would think the 2007 film wouldn't inspire [[SugarWiki/HeartwarmingMoments Leo/Don]] or [[HypocriticalHeartwarming Raph/Mikey]] fanworks but... Sometimes fans write them as [[NotBloodSiblings adopted brothers]] due to the franchise not clarifying if they are from the same parents, but most keep them blood siblings.
* Wanda and Pietro Maximoff, aka ComicBook/ScarletWitch and ComicBook/{{Quicksilver}} from the ''Comicbook/{{The Avengers}}'', were seen in this light, especially Pietro and his overprotective instincts. In the alternate universe title ''ComicBook/TheUltimates'', [[BrotherSisterIncest however...]]
* ''ComicBook/PowerPack'', being a sibling team, gets this a lot. In the all-ages version, Jack and Katie get this from some fans due to their constant bickering. [[http://asylums.insanejournal.com/scans_daily/21731.html A sweet moment between their future selves]] doesn't help due to the [[DoesThisRemindYouOfAnything way]] [[RelationshipWritingFumble it's drawn]].
* A number of Franchise/{{Superman}} and Comicbook/{{Supergirl}} fans ship both characters together despite being first cousins, either because they think there's no getting around the "Kryptonian of Steel, Human of Kleenex" trouble or because they genuinely think Clark/Kal and Linda/Kara make a good couple. To be fair, Silver and Bronze stories provide plenty of fuel, accidental innuendo and subtext if you know where look ([[http://www.orgamesmic.com/wp-content/uploads/2013/07/superman-supergirl-kiss.jpg Action Comics #260]], [[http://static.tvtropes.org/pmwiki/pub/images/actioncomics270_page027.jpg Action Comics #270]], [[http://4.bp.blogspot.com/_pScx8BN4h3s/SMkfbsSeQCI/AAAAAAAAA_c/_XIlCBhpesg/s1600-h/action+289+pan+5.jpg the infamous Action Comics #289]], [[https://lh4.googleusercontent.com/-42hj4CP59UU/TW0EOjbIjyI/AAAAAAAALSk/MyJ0VPlDuGo/s1600/sm+309-04.jpg Superman #309]] during the ''Comicbook/KryptonNoMore'' story arc, [[http://30.media.tumblr.com/tumblr_lvzhjklUch1r2ntbyo1_500.png this panel]] from ''Literature/TheSuperdictionary''). Fanfic writers such as [[https://archiveofourown.org/users/megamatt09/pseuds/megamatt09 Megamatt09]] have penned long tales featuring them together.
* ComicBook/{{Daken}}'s private thoughts about little "sister", ComicBook/{{X 23}}, upon seeing her in action once their various conflicts, double-crossings, and manipulations are put aside so they can focus on dealing with Colcord are out of the way, can easily be read with a romantic subtext. And considering this ''is'' [[AnythingThatMoves Daken]] we're talking about... it certainly puts fuel into the fire among some of the fans and makes Daken one of Laura's [[LauncherOfAThousandShips many fandom pairings]].
* Franchise/{{Batman}}:
** Especially amongst the LGBTFanbase and {{Yaoi Fangirl}}s side of DC fans, a popular ship is ComicBook/{{Nightwing}} and Batman. Though there's no [[NotBloodSiblings blood relation]], Bruce has raised Dick since he was at minimum 12 (sometimes younger). The two have either a father-son bond or a brotherly bond DependingOnTheWriter.
** An even more popular ship is Jason Todd with Dick. The two are adopted brothers with a knack for the CainAndAbel routine.

[[folder:Films -- Animation]]
* ''Disney/{{Frozen}}'' fans love shipping the sisters Elsa and Anna. Even though she has a male love interest, Anna spends the entire movie wanting to see Elsa, wanting to spend time with Elsa, worrying about Elsa more than anyone else, and risking her life to save Elsa, fulfilling the "prince rescuing the princess" role. For her part, Elsa's fear of showing off her ice powers to anyone and hurting her sister has an [[DoesThisRemindYouOfAnything "in the closet" subtext thing]] going on. And in the end, the movie subverts the trope of [[spoiler:TrueLovesKiss by having the love that saves Anna be her sisterly love of Elsa]].
* Periwinkle and Tinkerbell from ''WesternAnimation/DisneyFairies'' have a relationship quite comparable to Elsa's and Anna's; in fact, some consider them the proto-Elsanna. They're played up in a way that resembles StarcrossedLovers, are very affectionate and are literally compared to a pair of starcrossed lovers. Understandably, many ship them.
* ''Disney/MeetTheRobinsons'' has some fans who ship Wilbur and [[spoiler:Lewis, his father]]. The ship is aptly referred to as "Timecest".
** There's even a small shipping with Wilbur and mother, Franny Robinson, considering how they first met accidentally in the present where he makes the mistake of insulting her as an "annoying little girl" causing her to show off her karate moves to him (with a smile...) and he has to help her collect all her pet frogs. Even in the future, the way she hugs and kisses her son after surviving a near-fatal encounter with the T-Rex proves to be a little unnerving (not to mention a little more than motherly by the looks of it).
* The most popular ''Disney/BigHero6'' ship by far is Tadashi and his younger brother Hiro. [[spoiler:The fact that Tadashi dies within the first twenty minutes is usually ignored]].
* Arrow and Rudolph is a pretty popular pairing for fans of ''WesternAnimation/RudolphTheRedNosedReindeer1998'' due to their rivalry making for good FoeYay. Most fans do not notice they're cousins, likely because it's never directly stated; you only realize it when you pair a statement that Cupid is one of Rudolph's uncles with a later statement by Arrow saying that Cupid is his father.
* Happened accidentally with ''Anime/WhenMarnieWasThere''. Prior to release, many were clamouring that it was Ghibli's first movie about a same-sex romance or, at least, an [[HideYourLesbians implied one]]. However, it turns out Marnie is the protagonist's [[spoiler:''grandmother'']]. A lot of complaining and AbandonShipping occurred but many either [[FanonDiscontinuity ignored]] that or went with it.

[[folder:Films -- Live-Action]]
* In ''Film/RepoTheGeneticOpera'', Luigi and Amber. Particularly the bit where she knees him in the groin and licks his ear at the same time. According to their brother Pavi's myspace page, ''he'' and Amber are also rather unhealthily close. And a surprising number of fans [[FoeYay ship Luigi and Pavi]] (or [[PortmanteauCoupleName "Pavigi"]]).
* In a director's-cut scene from ''Film/TheLordOfTheRings: The Two Towers'', many of who we'll call Stewardcest fangirls point for evidence to this moment that's very subtle, but oddly difficult-to-explain-otherwise when you notice it: Denethor dismissively comments about his younger son, Faramir, "I know his uses. They are few." Now think about the implications of the word "use." And rewind and look at Boromir's expression again: It's not "oh, dad, you're so mean", it's ''embarrassed''.
* The ''Franchise/{{Halloween}}'' fandom really likes the Michael/Laurie pairing even though he wants to kill her.
* Franchise/MarvelCinematicUniverse:
** Film/{{Thor}} and Loki may be the most popular ship in the Franchise/MarvelCinematicUniverse, which is saying a lot.
** From ''Film/AvengersAgeOfUltron'' we have Wanda and Pietro Maximoff, following in their comic counterparts' footsteps.
* The most popular pairing in the fandom for ''Film/HanselAndGretelWitchHunters'' by far is Hansel/Gretel.
* In ''Film/PacificRim'', two (or in one case three) member teams pilot giant robots using the techno-telepathic Drift. Between the very intimate memory sharing and emotional connections, special "drift compatibility" needed between pilots (and the one successful Drift compatibility trial seen on screen being described as akin to a sex scene by the director) and the fact that a pretty large number of teams seem to be related, incest is a pretty common in the PR fandom. The most prominent example is the lone parent/child team of Herc and Chuck Hansen, which also happen to be one of the most shipped pairings in the fandom. Probably helped that other characters comment on Chuck's "daddy issues", that supplemental material and WordOfGod states that Herc never remarried after Chuck's mum died and that Chuck never dated at all, and that the age gap between their actors is only a bit more than a decade.
* Not only did a lot of ''Franchise/StarWars'' fans ship Luke and Leia back in the day, but so did a lot of merchandise, advertising, and spin-off material (most infamously ''Literature/SplinterOfTheMindsEye'', published before ''Film/TheEmpireStrikesBack''). Nowadays, you have to look to find the, but it's still around; both relics of the original ship and new shippers.

* ''Literature/HarryPotter'':
** Many fans think that Bellatrix and Narcissa fit the bill for this and write extensive fanfics about it. (WordOfGod confirmed that Bellatrix loves Voldemort above all else; some fanfics manage to get around this fact.)
** Fred and George have a veritable library of slash work dedicated to them, even though [[http://i29.tinypic.com/zwib29.jpg their actors are disgusted by it all]].
** Ron and his sister Ginny. Ron is quite annoyed by the fact that Ginny dates Dean and he silently interferes with her and Harry's relationship at first, but he relents later and becomes more accepting of their relationship.
* ''Literature/TheChroniclesOfNarnia'' has Pevencest. Considering all four main characters are siblings, there really isn't a whole lot of shipping alternatives.[[note]]Well, except for Caspian. And he is widely shipped with ''all'' of the four Pevensie.[[/note]] The first book implies they're the only humans that live in Narnia, without mentioning the fact that there are other lands around Narnia in which reside other people. So it's either incest or [[InterspeciesRomance bestiality]] -- take your pick. Pevencest comes in all possible configurations of the four, but Peter/Susan and Edmund/Lucy are the most popular, and serve as a nice pair of ShipMates. Though there's a whole lot of Peter/Edmund, too, since people love their SlashFic.
* ''Literature/ASongOfIceAndFire'' has this in abundance, not exactly helped by the canon being quite bold about incest -- such as cousin marriage being quite common in Westeros, a certain royal family marrying siblings together, and there being a well-known {{twincest}}uous pairing in another family. Many fans ship characters the same way:
** In addition to shipping Jon Snow with girls who aren't related to him (Val, Ygritte) and a ''distant'' cousin (Alys Karstark), fans also ship Jon with Daenerys Targaryen, Sansa Stark, and even Arya Stark. Sansa and Arya are both Jon's half-sisters and if the popular theory of [[spoiler:Jon's parentage]] is true in the books (as it is in the [[Series/GameOfThrones television adaptation]]), [[spoiler:Daenerys would be Jon's paternal aunt, and Sansa and Arya would be Jon's blood cousins but raised as his sisters.]] These pairings may be due to Jon being a LauncherOfAThousandShips, but he gets shipped with his relatives quite a bit. The Arya one is not helped by an initial draft of the books that had Arya and Jon falling in love with each other to their mutual horror (although, this same outline also included Catelyn being killed by the Others, Tyrion falling in love with Arya as well, Benjen being Lord Commander of the Night's Watch, etc.).
* Franchise/TolkiensLegendarium:
** ''Literature/TheLordOfTheRings'': Merry and Pippin are first cousins and are often shipped together by fans. Sometimes Frodo, more distantly related to both of them, is thrown into the mix as well. See ''FanFic/BagEnders'''s "Random Slashy Interludes" for a prime example.
** Perhaps one of the most popular pairings in ''Literature/TheSilmarillion'' is Maedhros/Fingon; these two share a grandfather, Finwë. As do Celegorm and Aredhel, also paired rather often. And then there's [[FoeYay Curufin/Finrod]], which is popular despite the fact that canonically Curufin sent Finrod off to his death and tried to steal his throne.
** Then there's Fëanor/Fingolfin, who are half-brothers and... [[{{Understatement}} don't get along well in canon]].
*** The house of Finwë as a whole is very popular and more generally EveryoneIsRelated.
** Most fanfic treats the canon [[BrotherSisterIncest Túrin/Niënor]] pairing as tragic, like [[Literature/TheChildrenOfHurin the book]] in which they're the title characters -- but there's fanfic.
** As soon as the first ''Film/TheHobbit'' movie came out, there was an explosion of Fíli/Kíli slashfic. Many (but not all) of them operate from the canonical statement that dwarves love only once, and assume that the brothers have bonded to each other. Reactions of those around them vary from complete acceptance to revulsion.
* ''Literature/WarriorCats'':
** Hawkfrost/Brambleclaw, which has its own [[IdiosyncraticShipNaming ship name]]: Brothershipping. They're half-brothers, which is probably the only reason it isn't banned from discussion on Website/WarriorsWish.
** The reveal that [[spoiler:Firestar and Scourge]] are half-brothers means [[spoiler:Altershipping]] also falls under this trope.
* ''Literature/PercyJacksonAndTheOlympians'': Since shipping any demigods together is both incest and not. The books say that the only people in camp who are off-limits incest-wise are those with whom you share a godly parent--though these seems kind of contrived. If you take a broader view, the gods are related somehow, so all campers are part of the same family, usually cousins or something--and since the Greek gods didn’t let incest stop them, why should their kids?
** Percy and Annabeth. Despite being closely related via their respective parents, Poseidon and Athena (they’re first cousins once removed), [[spoiler:they get together by the end of the series]].
** Some fans pair Percy and/or Annabeth with their demigod [[KissingCousins cousins]], including Thalia (Zeus's daughter) with Percy and Annabeth with Luke (Hermes's son). Annabeth also has a crush on Luke early in the series.
* ''Literature/ASeriesOfUnfortunateEvents'' had a small Violet/Klaus fandom that got quite a bit larger after the release of the [[Film/ASeriesOfUnfortunateEvents movie adaptation]]. This is no surprise, considering they're a BrotherSisterTeam who has been [[PromotionToParent Promoted to Parents]] for their baby sister, and the two of them are pretty much the only people they can trust.
* A strict NoHuggingNoKissing policy during the original run of ''Literature/TheHardyBoys'' (alongside the stressful adventures giving the boys a very powerful brotherly bond) led a lot of people to acknowledge that Frank and Joe seemed very indifferent to their respective girlfriends Callie and Iola and way more interested in each other.
* Despite them being mortal enemies and having strong canon pairings with people of no blood-relation to them, Sam and Caine have been shipped together in the ''Literature/{{GONE}}'' fandom, and it's actually pretty popular. The ship is known as "Saine"... or "{{twincest}}".
* ''Literature/TheDresdenFiles'' fanbase commonly ships Harry with his half-brother, Thomas (usually ignoring the fact that both of them have serious female love interests). This is probably because Thomas is an [[CharmPerson incubus]], who naturally arouse sexual feelings in those around them, and because it was several books before said relation was revealed. The fact that Thomas masquerades as a gay hair dresser and they were MistakenForGay as a couple at least once in series (which they would later use to their benefit) doesn't help matters.

[[folder:Live-Action TV]]
* This is referred to by the ''Series/{{Firefly}}'' fandom as "CSI" or "Crazy Space Incest", seeing this between River and Simon Tam. This may have something to do with how closely they fulfill the traits of LittleSisterHeroine--River endearing, somewhat clingy, in need of protection fairly often, and they both absolutely adore each other. Creator/SummerGlau's [[http://www.youtube.com/watch?v=9JCvpFG-Ll4 opinion on the matter at 0:35]]. Creator/SeanMaher seemed to approve, though.
* Justin and Alex in ''Series/WizardsOfWaverlyPlace'' are the FanPreferredCouple, to the point where the pairing used to have a separate Incest Yay page until it was sent [[http://fetishfuel.wikia.com/wiki/Incest_Yay%3AWizards_of_Waverly_Place here]].
* Quite common in ''Franchise/KamenRider'' series. Especially ''Series/KamenRiderKiva'' and its many bathing scenes. However, "Kivacest" typically refers not to Wataru and Otoya, despite their ''epic'' TimeTravel-enabled bath scene (with back scrubbing!), but to Wataru and [[spoiler:Taiga]], who turns out to be his brother.
* ''Series/{{Supernatural}}'':
** The Wincest shippers see this between brothers Sam and Dean Winchester. During the early seasons, it was unquestionably ''the'' [[FanPreferredCouple most popular pairing]] in the fandom.[[note]]For the first few seasons, slash-ship options were pretty much limited to incest or RPF, and het-shipping would require characters who were either dead, not mentioned beyond one episode, or generally reviled by the fanbase. The ridiculous chemistry the two main actors have only contributed.[[/note]] Some fans took it so far that they would even ship the actors together as well. It's died down some since Castiel showed up,[[note]]the current FanPreferredCouple is Dean/Castiel, but Sam/Castiel and Dean/Sam/Castiel have their fans as well,[[/note]] but the Wincest fanbase is still significant. Lampshaded in one episode where they discover the fanfic written about them.
--->'''Dean''': They know we're brothers, right?\\
'''Sam''': Doesn't seem to matter.
** Since all of the angels are canonically siblings, shipping any of them together falls under this. It's sometimes called "angelcest" or "wingcest" within the fandom. The most popular of these pairings is probably [[ArchangelMichael Michael]]/[[{{Satan}} Lucifer]], perhaps because it mirrors the Winchester pairing.
* ''Series/{{Heroes}}'':
** Maya and Alejandro Herrera are twins who seem to be a little too close to each other; even their powers require physical connection. You didn't need to ask the fans twice.
** Peter and Nathan Petrelli are brothers who are extremely close, despite an age difference of at least 13 years. There is a reason they're the most popular slash pairing in the show. Not helping is how friendly Adrian Pasdar and Milo Ventimiglia are in real life.
** Peter and Claire seem to be closer than one would expect of uncle and niece, and their shipping fandom only slowed down slightly after that little revelation. Then there's [[CastIncest Milo and Hayden's off-screen relationship]].
* ''Series/{{Dexter}}'':
** Dex naturally gets much shipping with [[spoiler:his brother Rudy/Brian]], what with all the [[DoesThisRemindYouOfAnything sexual symbolism]] the show blends with his murdering.
** The show runners tried to keep the [[CastIncest Michael C. Hall and Jennifer Carpenter marriage]] quiet for a while specifically to avoid this trope. It didn't work. They clearly changed their minds, though (Hall and Carpenter's divorce may have played a part) -- as of Season 6, Deb lusting after her brother is canon. It helps that Dexter and Debra aren't blood-related and were instead just raised as siblings.
* ''Series/{{Chuck}}'' was [[WhatCouldHaveBeen originally intended]] to have an extra character in the main cast, a love interest for the titular hero. After it was decided she overcomplicated things, she was cut, and all her important lines given to Chuck's sister. The slightly flirty dialogue, coupled with the siblings' chemistry, made this stand out to more than one fan.
* When ''Series/HomeAndAway'' revealed that sisters Charlie and Ruby Buckton were actually mother and daughter, one website brilliantly proclaimed that it made shipping them feel even more wrong. They even seem to have acquired their own couple portmanteau, even if it is mostly used in a familial context.
* ''Series/{{Revolution}}'' has a small, but devoted sector of Charlie/Miles shippers. They are niece and uncle, and possibly father and daughter considering Miles affair with Rachel, but share a lot of tropes usually reserved for romantic interests. A RelationshipWritingFumble may have also happened since they have a lot of BelligerentSexualTension that turns into UST later. They also have their fair share of heartwarming moments.
* ''Series/{{Glee}}'':
** Hummelcest between Burt and Kurt Hummel, a rare example of a father/son incest. Considering that they cannot have a scene without declaring their love for each other, it shouldn't be a surprise.
** After Blaine got a brother who is [[MrFanservice even more handsome]] than he is, we have Andercest. Not at all helped (or immensely helped, for those who like this sort of thing) by the line "We're not just brothers, right?" said while standing with their [[AlmostKiss faces mere inches apart]].
* ''Series/{{Angel}}'': There ''are'' fans who have written mother-son Darla/Connor and father-son Angelus/Connor incest stories. The former despite the fact that Darla ''died'' to give birth to Connor.
* ''Series/TheBorgias'': [[ParentalIncest Rodrigo]]/[[DaddysGirl Lucrezia]] and [[SiblingRivalry Cesare]]/[[FoeYay Juan]] shippers exist in abundance. And, of course, the FanPreferredCouple is [[BrotherSisterIncest Lucrezia/Cesare]]. Even historians support that one. [[spoiler:And it ''did'' become canon...]]
* The ''Series/{{Frasier}}'' fandom has some Frasier/Niles shipping, otherwise known as "Cranecest".
* The ''Series/LifeWithDerek'' fandom give us [[NotBloodSiblings Derek and Casey]] aka [[PortmanteauCoupleName Dasey]].
* There's a huge and passionate faction of [[BrotherSisterIncest Klaus/Rebekah]] shippers in ''Series/TheVampireDiaries'' and later ''Series/TheOriginals'' fandoms. Joseph Morgan and Claire Holt's chemistry and dialogs straight out of dark romance novel? Check. Eye sex and tension? Check. Jealousy, obsessiveness, highs and lows? Check. Makes Klebekah the royal couple of the show and one of the most popular ships.
* ''Series/TheWaltons'', a much-loved Depression-era drama from the 1970s, contains several examples, mostly because it features seven siblings of similar ages. John-Boy and Mary Ellen, the eldest siblings, were infamous in the early seasons for being [[IncestSubtext a little too close]]. John-Boy tells Mary Ellen that her breasts will grow, gives her flowers because he wanted to be her "first," and frequently dances with and consoles her. Basically, there's plenty of [[UnresolvedSexualTension sexual tension]] to go around. Jason and Erin, younger siblings, also seemed very fond of each other, though this was most likely because of actor chemistry.
* ''Series/{{Arrow}}'':
** Right from the pilot, fans already commented that Oliver has more chemistry with every other female character, including his sister, than with his ex-girlfriend. It doesn't help that by giving her the nickname "Speedy", the writers seem to have destined Thea to be his sidekick, and that despite a slight name change, the character is clearly based on comics character Mia Dearden (their first names sound similar, she was shown having a trophy for archery in her room in the pilot, and her middle name was eventually revealed to be "Dearden") whom comics Oliver has shown romantic interest towards in the past. And then after Thea came back from Corto Maltese, she asked him to move in with her.
** In hindsight, turns out anyone who shipped [[spoiler:Tommy/Thea]] inadvertently fell into this trope.
* ''Series/{{Skins}}''
** There’s a lot of subtext between [[BrotherSisterIncest Tony and Effy Stonem]], and it's made "Stonemcest" a surprisingly popular ship in the fandom.
** [[{{Twincest}} Emily and Katie Fitch]]… or, at least, [[{{Starboarding}} one-sided]] from Katie to Emily.
* Deliberately invoked in-story by Richard III in the BBC/Starz series ''The White Queen'', as per his explanation to his wife Queen Anne that he is not actually having an affair with his niece Elizabeth, but that he just wants everyone to think he is, since she is betrothed to his political rival Henry Tudor, and that [[DeliberateValuesDissonance by cuckolding Henry, he will cost him political support]]. [[spoiler:After Anne's death, he and Elizabeth actually do the nasty, though]].
* More than a few people have mistaken Zelda and Hilda from ''Series/SabrinaTheTeenageWitch'' for a couple. The issue comes mostly from mistaking Sabrina calling them "aunts" as referring to one of them being her bio-aunt and the other her lover.
* ''Series/GameOfThrones'':
** Jon Snow is shipped with Daenerys Targaryen, who [[spoiler: -- unbeknownst to Jon and Daenerys -- is Jon's [[SurpriseIncest paternal aunt]]]] while other fans ship Jon with Sansa Stark, who is Jon's [[spoiler:cousin, but raised as his]] half-sister. In Westeros, both matches are ''socially'' plausible: [[KissingCousins cousin marriages]] are considered fair game in Westeros, and the Targaryens have long since had an incest free pass.
** In Season 7, [[spoiler: Dany and Jon]] [[SecondLove fall in love]] and [[spoiler:[[RelationshipUpgrade do it]]]] -- blissfully unaware of their [[SurpriseIncest connection]].
* ''Series/ItsAlwaysSunnyInPhiladelphia'':
** Twins Dennis and Dee Reynolds, due to the large amount of IncestSubtext between them (which included [[IncestuousCasting playing lovers]] in Charlie's "The Nightman Cometh" play, posing as a married couple more than once, Dennis believing he drunkenly impregnated Dee at a Halloween party, and then there's what goes on in "The Gang Broke Dee"). Fans have noted that Dennis, for all his putting down of Dee's appearance and dreams, also has the most PetTheDog moments towards her; Dee herself doesn't vocally reciprocate it, but she is shown to [[AwLookTheyReallyDoLoveEachOther still care for him]]. Considering how screwed up all of the main characters are, it wouldn't be surprising if this one actually became canon at some point; their actors [[WordOfGod themselves have stated]] Dennis and Dee have a very ''deeply'' dysfunctional and codependent relationship that makes them, in a way, perfect for each other.
** Frank and Charlie are also disturbingly close to each other and engage in a lot of strange and intimate acts together. The only thing stopping them from definitively falling into this trope is the fact that we don't know for sure whether Frank is Charlie's father.
* ''Series/{{Riverdale}}'':
** The Blossom twins, Jason and Cheryl, get this from fans. It doesn't help that one of the writers is behind ''ComicBook/AfterlifeWithArchie'', which had them in a relationship. It's even speculated by characters in-series that Cheryl liked her brother a bit ''too'' much, but he didn't like her back… so she [[SiblingMurder shot him]]. The series jossed that theory but fans still ship them nevertheless.
** Shipping Jughead with his ''father'' is a fairly prominent ship in the fandom.
* Shipping Kara with her [[NotBloodSiblings adopted sister]] Alex is one of the most popular ''Series/{{Supergirl}}'' ships. Like a lot of other examples, it helps that they share a lot of intimate moments and have a lot more chemistry with each other than their love interests. And it helps that Alex is gay.

* WebVideo/NotLiterallyProductions' FilkSong "I Love It" is a shipper's anthem. The second verse describes this kind of shipping.
-->I know that they are siblings but I think there's something more\\
If she weren't dating that guy, they'd be banging, I am sure.\\
The third scene in episode four, come on, [[LongingLook look at him stare]].\\
{{Twincest}} can't really be that bad--\\
I don't care, I ship it!

* ''Theatre/{{Hamlet}}'''s [[OedipusComplex subtext with his mom]] inspired a whole ''profession'' of this trope. Doesn't help that [[AgeLift he]] is often older than [[PlayingGertrude her]].
* ''Theatre/RichardII'' (particularly as presented in ''Series/TheHollowCrown'' and/or the RSC version starring Creator/DavidTennant) has [[FoeYay Richard/Bolingbroke]], as well as [[UnequalPairing Richard/Aumerle]] (who share a [[KissingCousins lengthy kiss]] in the RSC version), all cousins. (Specific to the Hollow Crown version of ''Theatre/HenryIVPart1'', the sight of Creator/JeremyIrons slapping Creator/TomHiddleston caused a few [[ParentalIncest fandom ripples]].

[[folder:Video Games]]
* Alfred and Alexia Ashford in ''VideoGame/ResidentEvilCodeVeronica''. A case where the IncestSubtext may have been intentional from the developers' part.
* ''Franchise/FireEmblem'':
** The king and queen of this trope would be [[VideoGame/FireEmblemJugdral Eldigan and Raquesis]], while the prince and princess would be [[VideoGame/FireEmblemTheSacredStones Eirika and Ephraim]].
** The romance system in ''[[VideoGame/FireEmblemJugdral Genealogy of the Holy War]]'' allows for KissingCousins, of which two pairings are actually half-sibling incest[[note]]Because Aideen and Briggid are identical twins, any children they have are genetic half-siblings. This does not preclude the pairings of Lana/Faval and Lester/Patty[[/note]].
** The romance system in ''VideoGame/FireEmblemAwakening'' allows for cousin marriages as well, although the NA/PAL releases {{Bowdlerize}}d this slightly by referring to such pairings as "[[PlatonicLifePartners companions]]" rather than husband and wife. However, they failed to do this for the ''aunt/nephew or uncle/niece'' pairings that are possible by pairing Chrom with either Maribelle or Olivia and then pairing one of the resulting children with the Avatar and the other with Morgan.
** It seems the most popular pairings in ''VideoGame/FireEmblemFates'' involve pairing the Avatar with his or her relatives. The Female Avatar is commonly shipped with her adoptive brothers, Xander and Leo, and with her ''actual'' brother, Takumi ([[spoiler:while they're actually NotBloodRelated, they ''think'' they are]]). Meanwhile, the Male Avatar is commonly shipped with [[spoiler:Azura]], who ''looks'' to not be related to him [[SurpriseIncest but is actually]] [[KissingCousins his long-lost cousin]]. And yes, the game ''actually lets you'' marry any of these characters, even in the West.
*** Velouria is very clingy towards her parents, especially her father Keaton. Though this is explained by her parents leaving her months at a time because they have to fight in a war, it doesn't stop certain fans from seeing Velouria's attachment as something far less wholesome.
* Fraternal twins Anna and Mihael in ''VideoGame/DragonValor''.
* ''Franchise/FinalFantasy'':
** Faris/Lenna from ''VideoGame/FinalFantasyV'' has some popularity. The general interpretation for this pairing is that Faris's BigBrotherInstinct[[note]]technically ''sister'', but this is Faris[[/note]] towards Lenna is actually romantic interest.
** From ''[[VideoGame/FinalFantasyX2 FFX-2]]'' we have [[KissingCousins Yuna and Rikku]].
** Due to the nature of "[[{{Subtext}} Subtle Romance]]" of ''VideoGame/FinalFantasyXII'', some fans decided to assume that Basch has no eyes for anyone but his twin brother Noah/Gabranth and vice versa.
** And in ''VideoGame/FinalFantasyXIII'', there is Lightning and Serah.
* ''Franchise/MetalGear'': Solid Snake and Liquid Snake. It only gets worse once Liquid possesses Ocelot, who had a big gay crush on their father, especially since Big Boss is a TrulySingleParent.
* ''VideoGame/GoldenSun'':
** The most obvious is Felix and Jenna, who are siblings (and appropriately dubbed "[[SurpriseIncest Oopsie-shipping]]" by the fans).
** Fans also like to pair up [[FoeYay Alex and Mia]], who were confirmed to be cousins by ''Dark Dawn''. This one however is a special case, as the reveal only happened years after the first games, when the ship was firmly installed. Like the 4koma example below, this is a rather meta case of SurpriseIncest.
** A 4koma doujinshi, ''Golden Sun Gag Battle'', has Ivan [[PowerPerversionPotential trying out his new Reveal power]] on [[spoiler: Hama and Feizhi's clothes.]] To be fair, ''Gag Battle'' was published before ''The Lost Age'' outed [[spoiler:Hama as Ivan's sister]], making this a rather meta case of SurpriseIncest.
** ''VideoGame/GoldenSunDarkDawn'' brought several new sets of relatives to the table, with the (in)appropriate reaction from the {{Shipping}} fans. Nowell and Rief are treated as a joke couple in most cases, but shipping either of them with [[spoiler:Amiti]] is fair game... and, technically speaking, a distant enough relationship to be legal even by American standards.
* In the ''VideoGame/{{Touhou}}'' fandom every pair (or trio, in the case of the Prismrivers) of sisters is paired with each other to some degree. The Scarlet sisters are by far the most popular target, with the Komeiji sisters being second and working down from there, though shipping the Aki sisters with each other may simply be because they have such a small fandom shipping them with anyone else is rare.
* Hawke/Bethany has a surprisingly strong following in ''VideoGame/DragonAgeII.'' Isabela and Merrill weren't everyone's cup of tea, and Aveline wasn't a love interest. Cue a large amount of people shipping Hawke with his/her younger sister. There's also a considerably smaller, but still noticeable amount of shipping for Carver/Hawke.
* In ''VideoGame/TalesOfSymphonia'', [[spoiler:Kratos and Lloyd]] seemed awful subtexty to a lot of people. Some of them didn't [[AbandonShipping Abandon Ship]] after [[spoiler:it was revealed that [[LukeIAmYourFather Kratos is actually Lloyd's real father]]]].
* ''VideoGame/DeadOrAlive'' has a wide fandom of Kasumi-Hayate shippers. And easy to see subtext, especially on Kasumi's side, who went {{Yandere}} on Raidou for crippling her brother and wishes to return back to her village, so she can continue to live with Hayate. When one looks for dojinshis of ''Dead or Alive'', there's a good chance Kasumi-Hayate will be one of its pairings. Strangely enough, the ''much heavier'' subtext of Ayane towards her half-brother Hayate is not as widely followed. Full-blood Siblings are hotter than Half-Siblings? Of course, that doesn't account for the fact there's a surprisingly large amount of porn that features Kasumi/Ayane.
* ''Franchise/SuperMarioBros'':
** Toad and Toadette though it's possible that the fandom doesn't know they're brother and sister. Nintendo themselves [[FlipFlopOfGod can't make up their minds]] about whether they're siblings, friends, or what.
** This was bound to happen with Mario and Luigi themselves since they're the main characters and considering that they live together, do practically everything together and share a pretty strong brotherly love from the fact they have a tendency to [[ManHug hug each other]] in the ''VideoGame/MarioAndLuigi'' games and Luigi, in particular, is more obvious in his admiration for Mario. There's also the fact that they're some of the only human males in the canon that aren't outright {{Gonk}}s.
* Likewise, [[ThemeNaming Rock and Roll]] (or Franchise/MegaMan and Roll in the West), whose actual connection varies in their [[VideoGame/MegaManLegends various]] [[VideoGame/MegaManBattleNetwork incarnations]]. The same applies to [[HoYay Rock and Blues]] ([[MarketBasedTitle Mega Man and Proto Man]] in the west).
* Shadow The Hedgehog and Maria Robotnik from ''Franchise/SonicTheHedgehog'' have a strong shipping base despite treated like siblings, along with the fact Maria is a little girl who has been dead for ''decades'' by the start of the series. Admittedly many of the works at least age Maria into an adult and transform her into a hedgehog.
* ''VideoGame/BioShockInfinite'':
** It's near impossible to find a Lutece fan who doesn't ship them together. In fairness they're not really siblings, but [[spoiler:ScrewYourself]] isn't much better.
** [[spoiler:Booker and Elizabeth]] have an enormous fandom despite the whole [[spoiler:father and daughter]] thing that was kind of an important revelation.
* ''VideoGame/BlazBlue'':
** Brothers Ragna the Bloodedge and Jin Kisaragi are possibly the most popular yaoi pairing, and doubly supported by the [[FoeYay two's fierce rivalry]]. What really sells it is Jin's rather unhealthy obsession with killing Ragna, and the creators seem to love to play with it in the various Gag Reels.
** Ragna and Noel Vermillion, whose fandom weren't impeded at all by the revelation [[spoiler:Noel is a clone of Ragna and Jin's sister Saya]].
** Ragna/Nu ([[spoiler:who is also a clone, like Noel]]). Nu is a full blown {{Yandere}} for Ragna, and all of her interactions with him have very [[InterplayOfSexAndViolence overt overtones]].
* In ''VideoGame/DevilSurvivor'', the second most popular pairing for the protagonist his cousin Naoya. Most of this comes from Naoya's strange obsession with him, but, interestingly, the revelation that [[spoiler:Naoya and the protagonist are also brothers, and in fact the reincarnations of the original Cain and Abel, respectively]] only seems to have made the pairing ''more appealing'' to the fangirls.
* The "Squid Sisters", Callie and Marie, from ''VideoGame/{{Splatoon}}'' get shipped a lot. [[spoiler:It helps that they are [[KissingCousins cousins]], which makes it more acceptable to [[ValuesDissonance varying degrees.]]]]
* In the ''VideoGame/{{Undertale}}'' fandom, Sans/Papyrus (aka [[IdiosyncraticShipNaming Fontcest]]) is one of the more popular pairings, despite the fact that [[{{Skeletons}} they]] lack certain [[{{NonhumansLackAttributes}} attributes]].
** It's also worth noting that the fandom also ships [[spoiler: Asriel Dreemur]] with his adoptive sibling, [[spoiler: The First Fallen Child/Chara]]. To be fair, his actions throughout the game were borderline {{Yandere}} and it's been implied that [[spoiler: Asriel]] is the [[MoralityPet one thing]] [[spoiler: Chara]] [[MoralityPet genuinely loves and cares about.]] Not to mention, that as [[spoiler: Flowey]], he comes off a bit as a StalkerWithACrush [[spoiler: towards the player character [[WishfulProjection that may stem from him mistaking them as Chara]]]].
*** Though YMMV on whether or not this can be considered "real incest" since they're NotBloodSiblings.
* ''[[VideoGame/{{Onmyoji}} Onmyōji]]'' has this going on between Kuromujō and Shiromujō thanks to the former's huge BigBrotherInstinct and the (amnesiac) latter's stating that he has some sort of feelings toward Kuromujō in his in-game autobiography.
* ''Franchise/{{Pokemon}}'':
** Within hours of being leaked, the Striation triplets were subject to this. Even after the reveal that they were brothers, fans still shipped them together in all combinations or all three at once.
** Due to CounterpartComparison with Raygo from ''Anime/KillLaKill'', Lusamine from ''VideoGame/PokemonSunAndMoon'' sometimes gets shipped with her children [[spoiler:Gladion and Lillie]].

[[folder:Visual Novels]]
* ''VisualNovel/AceAttorney'' caters to this trope, but, when you think about it, it's not that surprising: there's shippers for Mia/Maya, Lana/Ema, Jake/Neil, Edgeworth×Franziska ([[NotBloodSiblings who are adoptive siblings]]), and even [[spoiler:Apollo×Trucy]], all of which have a fair bit of subtext to them. The two incestuous pairings that are by far the most popular in the fandom are [[spoiler:Dahlia/Iris]], from ''Trials and Tribulations'' and Kristoph/Klavier, from ''VisualNovel/{{Apollo Justice|Ace Attorney}}''. To be fair, many fans shipped [[spoiler:Apollo and Trucy]] before they knew they were siblings, and [[SurpriseIncest they themselves never found this out]].
* ''VisualNovel/HigurashiWhenTheyCry'':
** Rika and Hanyuu are one of the most shipped Rika pairings. It helps that they're ''very'' distant relatives [[spoiler:as Hanyuu died centuries ago]].
** Pairing the twins Shion and Mion isn't too rare. It doesn't help that Shion said she'd marry Mion if she was a boy, or that official art for the anime adaptation likes pairing them together.
* In the visual novel ''VisualNovel/{{Morenatsu}}'', it's not uncommon for fans to ship [[BigFun Tatsuki]] with his father [[PervertDad Tappei]].
* In ''VisualNovel/{{Danganronpa}}'', [[spoiler:[[{{Twincest}} Junko Enoshima/Mukuro Ikusaba]]]] is a rather popular ship, [[IdiosyncraticShipNaming which is nicknamed]] [[spoiler:"Despaircest."]] ''Dangan Ronpa If'' and ''Anime/DanganRonpa3'' have quite a bit of IncestSubtext on the latter's part.

[[folder:Web Comics]]
* Since Creator/JayNaylor's webcomic ''Webcomic/BetterDays'' contained actual {{Twincest}}, readers have been joking about something similar happening on its sequel ''Webcomic/OriginalLife'' ever since it got started. And early in the series there were definite undertones of [[BelligerentSexualTension BST]] between Janie and a [[KissingCousins cousin]].
* ''Webcomic/{{Homestuck}}'':
** John/Jade and Dave/Rose--confirmed ecto-siblings with a rather large shipping base. More on the latter, though.
** The amount of Bro/Dave shipping is unsettling when you find out that [[spoiler:Bro is not only Dave's brother, but he was also Dave's ecto-father]]. According to Google Trends, "Stridercest" (Dave/Bro, or sometimes Dave/[[spoiler:Dirk]]) got ''much'' more popular after Act 6 began, which was when [[spoiler:the post-Scratch versions of the Guardians were introduced]].

[[folder:Web Original]]
* Lenny and Elizabeth Priestly of ''Roleplay/SurvivalOfTheFittest'' v3 are seen by most handlers as having an... [[{{Twincest}} interesting relationship]], due to Lenny's protectiveness of her. Some handlers also ship Reiko and Reika Ishida (twins), and Rosa, Frankie, and Ilario Fiametta (triplets).
* In ''Blog/CinnamonBunzuh,'' an ''Literature/{{Animorphs}}'' ReviewBlog, reviewer Ifi ships Ax and Tobias (who are uncle and nephew) [[ScrewYourself while the latter is morphed into the former]].
* In a [[http://agrissas.tumblr.com/post/69590441030/the-rwby-s1-fandom-survey-results poll]] of 817 ''WebAnimation/{{RWBY}}'' fans (held after Volume 1), 23 said their {{OTP}} was Ruby/Yang, who are half-sisters. The ship is known as "Enabler". It isn't uncommon to see Ruby/Yang in Pollination ([[OneTrueThreesome Ruby/Weiss/Blake/Yang]]) fanworks, though many fans also just depict them as sharing girlfriends in that scenario.
** Going one generation up the tree, the [[MemeticMutation infamous]] "Entire Team" ship (Summer/Taiyang/Raven/Qrow) contains Raven and Qrow, who are sister and brother. Most supporters interpret it as "Taiyang ReallyGetsAround" to avoid the problem, but a full-on STRQ orgy isn't unheard of.

[[folder:Western Animation]]
* ''WesternAnimation/AvatarTheLastAirbender'':
** The Azula/Zuko shipper fandom was always significant, but the creators surely aren't making it too difficult with certain scenes. They have even (jokingly?) shipped Zuko's alter ego with Azula at a convention. On the flip side, Azula acts that way toward [[TheVamp just about everyone]].
** A lot of people give Zuko an [[ParentalIncest Oedipus Complex]], especially after ''[[ComicBook/AvatarTheLastAirbenderTheSearch The Search]]'', often with the idea that their familial affection doesn't overpower any sexual attraction due to years of separation.
* ''WesternAnimation/TheLegendOfKorra'':
** There's a Mako/Bolin fandom. Fans shipped them when they were revealed though the revelation that they're brothers caused most shippers to jump ship. Korra is ''usually'' in the [[{{OT3}} tangle]], but not always.
** [[spoiler:Tarrlok and Amon/Noatak]] became very popular after the season 1 finale, thanks to the buckets and buckets of angst. Who cares if [[spoiler:they both died]]? That's what {{Fix Fic}}s are for.
** Desna and Eska are a pair of CreepyTwins, so this comes into play naturally (again, Bolin is usually in the tangle, but not always). There's even an in-series joke about how ThereIsOnlyOneBed in their hotel suite, though Desna apparently sleeps in the bathtub.
* Lemongrab and his clone, Lemongrab 2, from ''WesternAnimation/AdventureTime'' are one of the most popular ships in the fandom, even after the two actually referred to each other as "brother" in the episode "Another Five Short Graybles". Alternatively, some shippers see this simply as clones and relationship companions, but not necessarily siblings.
* Yin and Yang from ''WesternAnimation/YinYangYo'' have a lot of this going on, especially since they're, you know, [[OppositesAttract opposites]].
* ''WesternAnimation/PhineasAndFerb'':
** In the early days, the title characters seemed to be the most popular ship, though that's ''mostly'' died down. Pairing one of them with their older sister Candace (biological for Phineas) is rarer but still done. [[http://www.youtube.com/watch?v=U872E53BnOk "Gitchee Gitchee Goo means 'I love you'"]]. Riiiiiiiiiiight...
** Suzy's attitude towards her ''much'' older brother is absolutely creepy, even for fans of this trope.
* Occurs in some segments of the ''WesternAnimation/{{Animaniacs}}'' fandom, though probably more because there aren't very many other shipping options.
* In ''WesternAnimation/{{Rugrats}}'' and ''WesternAnimation/AllGrownUp'', some people ship step-siblings Chuckie and Kimi together. On the other hand, Phil and Lil probably have more shippers and they're {{twin|cest}}s.
* Papa Smurf and Smurfette in ''WesternAnimation/TheSmurfs'', while not biologically related, get constantly shipped together in this fashion. It doesn't really help that [[{{Ephebophile}} Papa Smurf even has]] [[PervertDad that type of interest in Smurfette]]. This is fortunately averted in Sony Pictures' ''Film/TheSmurfs'' film series, as Papa Smurf treats Smurfette like a daughter.
* Cousins Ben and Gwen from ''WesternAnimation/{{Ben 10}}'', thanks to many AwLookTheyReallyDoLoveEachOther moments and meeting many of the requirements for BelligerentSexualTension. Indeed, the pairing is so popular that it's widely speculated the two getting StrangledByTheRedString in the first SequelSeries was an attempt at ShipSinking.
* ''Franchise/TeenageMutantNinjaTurtles'' get this treatment quite a lot, which is known as "turtlecest" in the fandom. The [[WesternAnimation/TeenageMutantNinjaTurtles2003 second animated series]] and the 2007 CGI movie are probably to blame, since they introduced a more complicated dynamic between the mighty foursome and, by the {{rule|ThirtyFour}}s of shipping, any tension can be interpreted in a [[UnresolvedSexualTension sexual]] way.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** Twilight Sparkle and her brother Shining Armor were very close when Twilight was a filly. In addition, Shining Armor is introduced in the episode where he is getting married. Twilight takes the news... poorly.
--->'''Twilight Sparkle''': [[DoubleEntendre Like two peas in a pod, we did everything together.]]
*** People have also noted that one of the few males who Twilight has ever shown attraction to on screen has blue hair, and has the same profession as him....
** One {{Wild Mass Guess|ing}} is that Applebloom is the ''daughter'' of Applejack and Big Macintosh instead of their sister. This is not helped by the packaging of one toy declaring that Applejack lives on Sweet Apple Acres with her husband, Big Macintosh (and her daughters, Apple Bloom [[CriticalResearchFailure and Granny Smith]]).
** Celestia/Luna, a.k.a. [[IdiosyncraticShipNaming "Princest"]], is the third most popular ship involving the princesses[[note]]The first and second being [[MentorShip Celestia/Twilight]] and Luna/[[LauncherOfAThousandShips Twilight]][[/note]]. Granted, they're [[PhysicalGod goddesses]]--incest is pretty common no matter [[Myth/ClassicalMythology what]] [[Myth/NorseMythology pantheon]] you're looking at. [[note]]It also doesn't help that there's no one else around who's even remotely close to them in age.[[/note]] Occasionally Celestia/Cadence pops up as a Princest ship, though in their case at least they're canonically not blood relatives (Celestia adopted Cadence as her niece).
** The fans wasted no time pairing up Marble Pie with Big Macintosh as soon as she'd had her first speaking ([[TheQuietOne sort of]]) appearance, despite the fact that they may or may not be cousins, albeit distant ones.[[note]]"fourth cousin twice removed by a fifth cousin", allegedly[[/note]]
** Everypony is gay for Braeburn according to the fandom, including his cousin Big Macintosh.
** Pinkie is very close to her sister Maud. Shippers haven't missed this. It helps that OppositesAttract.
** Due to her parents being super fans of her, fans have shipped Rainbow Dash with both of them.
* ''WesternAnimation/GravityFalls'': The Pines family has not one but ''two'' pairs of fairly widely shipped twins.
** "Pinecest" refers to the Dipper/Mabel pairing, due to Dipper constantly being worried and protective of his sister, particularly when it comes to her romantic endeavors. That the twins share a bedroom and in general are very comfortable with touching, hugging, and holding hands with each other gives more basis for fans of this pairing. Series creator Alex Hirsch has poked fun at it on the official Gravi-Team Falls Website/{{Tumblr}}:
--->'''Alex Hirsch''': For ages now I have lurked in anonymity, hiding in the shadows of the internet, watching as you've GIF'ed our jokes and shipped our characters and done unspeakable things to my dear Pines Twins. You... you've got some issues, Tumblr. We're all worried about you.
** Once it was revealed that [[spoiler:[[TheReveal Grunkle Stan has a twin brother]]]], they received similar treatment, with their ship name being [[spoiler: "Stancest". (They're also Pines by surname, but this prevents any confusion.)]]
* The Twins from ''WesternAnimation/{{Superjail}}'' have somewhat of a fanbase that interpret them as incestuous, based off their narcissism and closeness to each other. Certain lines (such as their "date" joke from an early episode) fueled the shipping, although the vague [[RapeAsComedy porn incident that traumatized them]] has been used by supporters ''and'' detractors of the ship to prove or disprove the dynamic being canon.
* It's been a common joke that the ComicBook/WonderTwins are incestuous. This was referenced to in one of the ''WesternAnimation/TheNewAdventuresOfTheWonderTwins'' shorts by Creator/AdultSwim, where Marvin mistakes them for watching porn together.
* ''WesternAnimation/TheAmazingWorldOfGumball'' has Gumball mostly being shipped with his family especially Darwin and Nicole.
* A lot of ''WesternAnimation/SofiaTheFirst'' shipping involves pairing Sofia with either of her step-siblings, Amber or James.
* ''WesternAnimation/ThePowerpuffGirls'':
** The most popular ship for Blossom, besides her and her SpearCounterpart Brick, is her and Mojo Jojo (which is also FoeYayShipping). Mojo was raised by Blossom's father and he was the one who accidentally [[ArtificialHuman created]] the girls, so depending on who you ask Mojo Jojo is either Blossom's older brother or her [[HasTwoMommies second father]].
** Considering the lack of characters to ship, the titular triplets get shipped in various combinations more than any other LesYay pairing.
** The Rowdyruff Boys can be seen as related to the Powerpuff Girls. They're {{Spear Counterpart}}s who were raised by Mojo Jojo, who is more-or-less related to the Powerpuff Girls himself.
* Most ''WesternAnimation/WeBareBears'' ships are between the bears, as there [[MinimalistCast aren't]] many characters in the first place and they (obviously) spend a lot of time together. They seem to be not blood related but are still clearly each other's brothers.
* ''WesternAnimation/TheLoudHouse'' takes the shipping UpToEleven with fans shipping Lincoln with any or all of his ten sisters crazier than the Jaime and Cersei Lannister shipping. Yes, it even goes to Lincoln x Lily, who is still a baby. Then, there's a canon scene where the girls are acting all crazy over Lincoln not having a girlfriend promotes this shipping even more. That's not even going into the ships where the sisters are paired with each other, [[Rule63 their genderbent counterparts from the mirror universe]], or Lincoln's GenderBender self Linka from that universe either. Lincoln and Lynn together is the most popular pair, to the point where it goes [[ShipToShipCombat head-to-head]] with Lincoln and his canon love interest Ronnie.
* Brothers Huey and Riley from ''WesternAnimation/TheBoondocks'' get shipped a lot. It's probably due to them being the only two young males in the cartoon and due to their constant bickering.
