Incest Yay Shipping

Go To

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, look at him stare.
Twincest can't really be that bad—
I don't care! I ship it!

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

Incest is a serious taboo among human beings—most cultures have an incest taboo.note  Despite this, or perhaps because of it, there is a significant amount of people interested in it, and this being 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 Ho Yay Shippers, 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, ignore the intended meaning, and Ta-da! you have subtext. There's also a good chance that you have 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 Incest Subtext. See also Ho Yay and Foe Yay Shipping for other shipping tropes that are based on fan-speculation, and Incest Is Relative page for a collection of other incest-related tropes.

  • 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 Incest Subtext. 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 is all parody, ranging from affectionate to absurdist. The phenomena is so prevalent, that GQ Magazine did an oral history of the ad.

    Anime & Manga 
  • Angel Sanctuary could not be more blatant about Setsuna and Sara, but some see this between Rociel and Alexiel as well.
  • BanG Dream! has the twin Hikawa sisters, Sayo and Hina. They were close as children, but Sayo's increasing envy of Hina's talent drove a wedge between them. Over time, Sayo starts to get over her jealousy and mend her relationship with Hina, who never stopped loving her unconditionally, which has been used as a basis to write them as having an incestuous relationship.
  • Beastars: Being the Launcher of a Thousand Ships, Legosi naturally gets this treatment quite a bit. Most infamously with his grandfather Gosha, but shipping Legosi with his mother Leano isn't unheard of either.
  • Ichigo/Uryuu is a relatively common Bleach Yaoi pairing. Later chapters of the manga revealed that Uryuu's father and Ichigo's mother were first cousins, making the boys second cousins, so this is also a case of Surprise Incest. The revelations have not much-dampened enthusiasm for the ship. Ryuuken and Masaki had a failed Arranged Marriage 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.
  • Bunny Drop has a step-sibling example. Many fans like the idea of six-year olds Kouki and Rin pairing up eventually, but most of these shippers also ship their guardians/parents Daikichi/Yukari. If Daikichi and Yukari ended up together then Kouki and Rin would end up step-siblings. In the manga itself, trying to avoid this issue is one of the reasons Daikichi and Yukari never got together, though the anime and film adaptations opt for Maybe Ever After.
  • Code Geass: There's enough of subtext in the series that it has its own Incest Subtext page, naturally leading to this. Lelouch/Nunnally, Lelouch/Euphemia (which is actually canon on Lelouch's side), and Cornelia/Euphemia are three of the most prominent examples; the rest can be found on that page.
  • D.Gray-Man has Komui and Lenalee Lee. Komui's rather intense sister complex does nothing to disprove this.
  • You'd be surprised at just how much of this there is in the Digimon Adventure fandom. Out of all the pairings between the characters, the ones between Tai/Kari and Matt/T.K. are among some of the more popular ones (aside from the Ho Yay that goes on within the fandom) for fans to focus their Shipping Goggles on.
  • The anime for .hack//Legend of the Twilight 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.
  • From Dragon Ball Z, 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 Eyeshield 21 is THE incest pairing of the fandom. It's not all that hard to see why, because Agon is (without a doubt) the most important person in Unsui's life, while Agon himself is a sociopathic playboy and memetic molester whose feelings for his brother are left ambiguous.
  • The three most popular pairings for Gou from Free! appear to be 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. Meanwhile, Rin has a whole Drama CD episode dedicated to the idea that he can't stand the idea of his sister dating anybody, its name being a parody of Oreimo's, to boot.
  • Fullmetal Alchemist:
    • Brothers Edward and Alphonse are one of the most popular shipping targets in the fandom, with Fullmetal Alchemist (2003) 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 Surprise Incest happened in the 2003 anime. Edward and Envy are a popular pair; however, near the tail end of the series, there's a twist: Envy is Ed's half-brother. Instead of abandoning ship, a lot of fans only saw this as making the pairing more interesting.
    • Shipping the Homunculi with each other in the manga/Brotherhood falls under this as they come from the same "father" and consider each other siblings. Greed/Envy has a decent following.
    • Shipping Scar with his deceased unnamed brother is not unheard of; especially with the first anime adding many comparisons and contrasts between them and the Elric brothers, though they were both shown to love a woman.
  • The Nishizumi sisters, Miho and Maho from Girls und Panzer are a surprisingly popular pairing among the fandom, since there are no male characters who are the girls' ages, and relatively little Les Yay. This is only reinforced by the revelation in Little Army that Maho in contrast to her initial impression as an Aloof Big Sister, loves Miho enough to live up to being Nishizumi heiress so that Miho will not have to.
  • Hetalia: Axis Powers: The very ship-happy fandom naturally has much of this, possibly influenced by Belarus' behaviour toward her brother Russia being canon and Prussia acting borderline-flirty around his brother Germany (though Prussia tends to flirt with almost everyone he encounters). Aside from the many cases of Not Blood Siblings being shipped, there are couples like:
    • Norway and Iceland; shipping increased somewhat after their familial connection was revealed, because it attracted shippers who liked the "forbidden" appeal.
    • Veneziano Italy and Romano Italy; since they represent different halves of Italy, they are technically half-brothers. The pairing is typically called Itacest, following along the lines of Germancest for Prussia and germany (or possibly predating the term).
    • 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 it's worth.
    • On the other hand, certain fans who dislike the US/UK pairing but don't want to go the Ron the Death Eater route like to invert this trope by taking a third option; namely, ignoring the duo's Belligerent Sexual Tension stunts and/or interpreting their other banter in the series as an example of platonic affection between siblings or a father-son relationship.
  • Hunter × Hunter: Some fans ship Killia and Alluka on the rare occasion the former isn't shipped with Gon. It's easy to see why since Killua is shown to be an extremely affectionate and protective brother with her, even more so than his interactions with Gon, and Alluka admires him since he's the only one who pretty much gives a damn about her.
  • JoJo's Bizarre Adventure: Although shipping the JoJos with each other is usually not popular because they have their own JoBros for each series, many in the Japanese fandom took a liking to shipping Jotaro/Josuke. This is probably because in canon, Jotaro acts like a Big Brother Mentor to Josuke (despite being his nephew) and Josuke always seems eager to listen to Jotaro.
    • Another popular ship inside of the Joestar family tree, even though it boils down to being a Crack Pairing, is Jolyne/Giorno. The most likely reason could be that they're the offspring of popular characters and mortal enemies Jotaro and DIO, and by the time that Jolyne reaches 19, Giorno is no longer 15. It also helps that, even though they're on the same family tree, their lineage is heavily separated, with Giorno being Jolyne's great-great-great-uncle.
  • Kill la Kill has Ryuko/Satsuki. They were already a pretty popular ship because they're so dead-set on defeating each other, but after they were revealed to be sisters, interest in it skyrocketed. To add even more fuel to the fire, the ending has the two embracing while naked.
  • Kido, Seto, and Kano from Mekakucity Actors are Not Blood Siblings but make it clear that they consider each other as siblings. It doesn't stop fans from shipping them.
  • Adoptive siblings Katarina and Keith Claes have this in My Next Life as a Villainess: All Routes Lead to Doom!, especially with Keith having one sided attraction to his older sister (who sees him as her cute younger brother), with it being one of the fan-preferred couples.
  • Naruto:
    • The number of Itachi/Sasuke fans would surprise newbies, and the size of the fandom only seemed to increase when Itachi died and Sasuke learned that Itachi had done everything — including killing the rest of his family — for Sasuke's sake.
    • 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 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 Karin is an Uzumaki. Their direct relationship is never clarified; however, fans streamline them into Kissing Cousins.
    • Naruto with both his mother Kushina and his father Minato are also popular incestous pairings, mainly because the parents look so 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 Strong Family Resemblance between them.
    • The titular protagonist of Boruto has been shipped with most members of his family, including his father Naruto, mother Hinata, sister Himawari, and aunt Hanabi.
  • The second most popular ship in Neon Genesis Evangelion is Shinji and Rei, since Rei is a the first girl Shinji encounters, both of them are soft spoken and quiet, and in both the Manga and the Rebuild films, have romantic tensions. However, the problem comes in the form of the fact that Rei is, in the Anime, a clone of Yui, or in the Rebuilds, has elements of Yui's DNA mixed with Lilith's, making him either fall in love with his mother or sister depending on the version.
  • The most popular No Matter How I Look at It, It's You Guys' Fault I'm Not Popular! ship is Tomoko and her brother Tomoki. possibly due to the small cast. And/or that Tomoki used to adore his sister years ago but is now embarrassed by the fact he wanted to marry her as a little kid.
  • One Piece:
    • The brothers Ace and Luffy are a fairly popular pairing in the fandom. And since the flashbacks to their childhood there is also now Sabo/Luffy, Ace/Sabo, and Sabo/Luffy/Ace One True Threesome 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 have three brothers and an older sister. Shipping abounds.
  • Oreimo is built on this, with a fanbase largely formed of people who want to see Kousuke and Kirino together. However, when they actually got into a relationship in the end, even most of the shippers found themselves disappointed with how it happened.
  • Most of Osomatsu-san shipping consists of pairing any number of Matsuno sextuplets together. Takahiro Sakurai even poked fun at it during the first seyuu event for the show, guessing that his character had a "pine" fetish (i.e. his brothers), with predictable results from his co-stars.
  • Hikaru and Kaoru Hitatchiin from Ouran High School Host Club 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.
  • PandoraHearts: Gil's younger brother, Vincent, is extremely possessive of him.
  • Panty & Stocking with Garterbelt 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 Peacemaker Kurogane, Tatsunosuke's overprotectiveness over his younger brother Tetsunosuke sometimes causes this.
  • Pokémon: Ruby & Sapphire: May and Max (Petalburgshipping) were popular enough to have an article written about potential hints on Bulbapedia, though it and most of the Anime shipping pages were removed in 2020 following a massive restructuring of the site.
  • Queen's Blade: The "Hide & Seek" manga adaptation features a romantic subplot about Elina and Claudette's hidden feelings for each other, because they're half-sisters. But during chapter 28, their middle sister Leina reveals she's known about it and says she's okay with it.
  • Re:Zero's twin-sisters Ram and Rem have a huge shipping following, due to being a very obvious example of a Pseudo-Romantic Friendship, especially in official art; so much so that they have become the fan artists' Fan-Preferred Couple over Rem/Subaru (though some take a third option and just pair them all together after Subaru starts having tension with Ram as well).
  • 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 denying having a sister to mean that Teru is in love with Saki.
  • Sgt. Frog 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.
  • Sket Dance: Bossun/Tsubaki is rather well-known inside the fandom after The Reveal that they are twins.
  • Tengen Toppa Gurren Lagann 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 Touch (1981), 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.
  • Mikan and Rito from To Love Ru are a fairly popular pairing; it even has in-universe support from Momo, who would include Mikan in The Harem Plan.
  • In Vampire Knight, the Kuran family has a history of incest, as seen in the current generation between Kaname and Yuuki. They remain a popular ship in the fandom, along with Zero and Ichiru.
  • There is a sizeable number of named and shipped pairs of this variety across the Yu-Gi-Oh! franchise.
    • Duel Monsters has Seto/Mokuba, for example, in that Seto would do anything in the early series for his younger brother.
    • From the spin-offs, gregarious examples such as the Twincest between Rio and Shark from ZEXAL in that they have rings gifted to each other, and later on in VRAINS, Ema and Kengo were mistaken for exes by many fans when in reality they were half-siblings related by their father and Kengo's disdain for his father's abandonment of he and his mother was causing strife.

    Asian Animation 
  • Pleasant Goat and Big Big Wolf: Some fans pair Wilie and Angelalily, even though they are cousins related through both of their parents. This ship is known as "香灰" in the Chinese community.

    Comic Books 
  • Wanda and Pietro Maximoff, aka Scarlet Witch and Quicksilver from the The Avengers, were seen in this light, especially Pietro and his overprotective instincts. In the alternate universe title The Ultimates, however...
  • Batman:
    • Nightwing and Batman are popular, especially amongst the LGBT Fanbase and Yaoi Fangirls side of DC fans. Though there's no 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 Depending on the Writer.
    • An even more popular ship is Jason Todd with Dick Grayson or Tim Drake. In either case the two are adopted brothers with a knack for sibling rivalry. Some even like to ship him with Batman cause of their complicated relationship after Jason's resurrection.
  • Daken's private thoughts about little "sister", 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 Daken we're talking about... it certainly puts fuel into the fire among some of the fans and makes Daken one of Laura's many fandom pairings.
  • Power Pack, 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. A sweet moment between their future selves doesn't help due to the way it's drawn.
  • A number of Superman and 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 to look places to look . Fanfic writers such as Megamatt09 have penned long tales featuring them together.
  • Teenage Mutant Ninja Turtles:
    • Half of the time Leonardo and Raphael fight, it comes off more like Belligerent Sexual Tension than actual Sibling Rivalry. 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 Leo/Don or Raph/Mikey fanworks but... Sometimes fans write them as adopted brothers due to the franchise not clarifying if they are from the same parents, but most keep them blood siblings.
  • Nate Grey a.k.a. X-Man had this with Madelyne Pryor, clone of his mother, Jean Grey. Their relationship was... complicated. The narrative fuelled a lot of UST between them, and while Nate backed off hard once he worked out their relationship, they remained the Fan-Preferred Couple (and writer preferred, going by the amount of suggestive writing). Certainly, Maddie didn't seem bothered, as the infamously suggestive cover of X-Man #41 shows - it literally says "If Maddie can't have Nate... no one can!". She flitted in and out of Nate's life in classic Tsundere fashion; sometimes nursing him back to health and sharing a slow dance with him, sometimes getting him into trouble for the hell of it, and rarely giving him any warning. Really, it's no wonder that when Nate created his own reality, the first rule was 'No Relationships'.

    Fan Works 
  • Child of the Storm has some In-Universe and out-of-universe shipping of Harry and his cousins, Jean and Maddie. While they're second cousins, which isn't necessarily taboo in the UK, and they had some enthusiastic shippers...
    • Jean acts like the big sister Harry never had, so he spends most of his time trying to wrestle his hormones into submission. While he mostly succeeds, Word of God observes that he hasn't exactly become blind to the way she looks.
    • Maddie, on the other hand... well, the chemistry between them is significant. It involves a lot of psychic intimacy, and Harry extending a mixture of the Power of Trust and Power of Love to help her break free from Sinister, who brainwashed her from infancy into believing she was an Artificial Human Living Weapon, in much the same fashion as Maddie's actual boyfriend. He's later shown thinking more than cousinly thoughts when he sees her in a nightie (to his own discomfort), which is brought up by a villain rooting through his mind - and Harry doesn't entirely deny it.
  • The MLP Loops: In-Universe. Changelings, being insects, don't have much of an incest taboo. Two changelings think Twilight Sparkle and Shining Armor would be a cute couple despite them being siblings. So they get really drunk and decide to act out a confession scene in public... and since they're shapeshifters, they do this as Twilight and Shining. No one is happy with them when they wake up.

    Films — Animated 
  • The most popular Big Hero 6 ship by far is Tadashi and his younger brother Hiro. The fact that Tadashi dies within the first twenty minutes is usually ignored.
  • Periwinkle and Tinkerbell from Disney Fairies 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 Starcrossed Lovers, are very affectionate and are literally compared to a pair of starcrossed lovers. Understandably, many ship them.
  • Encanto: Almost all the members of the Madrigal family are shipped in just about every combination. The most prominent ship is that between niece Mirabel and her uncle Bruno. They're canonically The Not-Love Interest, which is to say they have many of the trappings of love interests and their relationship is the most prominent one in the story. Bruno also canonically writes a telenovela that contains a romance between an aunt and nephew.
    Bruno: Their love could never be. […] Well, because she's his aunt and she has amnesia so she can't remember that she’s his aunt. It's like a very forbidden kind of…
  • Frozen fans love shipping the sisters Elsa and Anna. Even though she has a male love interest, Anna spends the entire first film 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 "in the closet" subtext thing going on. And in the end, the movie subverts the trope of True Love's Kiss by having the love that saves Anna be her sisterly love of Elsa. Many fanfics work around this by making them Unrelated in the Adaptation. Frozen II and the shorts Frozen Fever and Olaf's Frozen Adventure have all provided much material to keep this going.
  • In the CGI-animation/live action Easter film Hop, a lot of the fanbase shipped human protagonist Fred O'Hare (James Marshden) with his sister Sam O'Hare (played by Kaley Cuoco). As most of their interaction together come off as a couple rather than as siblings. Sam is the only adult female on-screen dedicating the most of her time to Fred, she lets him sleep over her bosses house (she housesits for her boss) and then drops over unannounced to check up on Fred. A lot of her behavior towards Fred comes off as "overly concerned girlfriend" rather than sister. Even Carlos shipped them together when he interviewed them in disguise at the behind-the-scenes movie premiere.
  • The Incredibles: Helen/Violet has a sizeable fandom, judging from the growing amount of fan art, femme slash fics, and H-videos of them being all over each other.
  • The Lion King:
    • There are a few fan-works that ship brothers Mufasa and Scar together.
    • Vitani is commonly shipped with Kiara and especially Kopa. It's never explicitly confirmed but it's likely that Vitani is Scar's daughter, making her the second cousin of Simba's cubs.
  • Meet the Robinsons:
    • Meet the Robinsons has some fans who ship Wilbur and 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).
  • In 101 Dalmatians, because 84 of the Dalmatian puppies were bought and paid for by Jasper and Horace before being rescued and Happily Adopted by Pongo and Perdita along with their 15 puppies, many of the fanbase ship them together in fan works since the puppies are Not Blood Siblings.
  • Arrow and Rudolph is a pretty popular pairing for fans of Rudolph the Red-Nosed Reindeer (1998) due to their rivalry. 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 When Marnie Was There. Prior to release, many were clamouring that it was Ghibli's first movie about a same-sex romance or, at least, an implied one. However, it turns out Marnie is the protagonist's grandmother. A lot of complaining and Abandon Shipping occurred but many either ignored that or went with it.

    Films — Live-Action 
  • Back to the Future: There are quite a few fans who like to pair Marty up with the past version of his mother Lorraine. There are a few fanfics about it and some sites even discuss how they would (in their opinions) work as a couple.
  • A not-insignificant portion of the fans for Doom is solely made up of those who ship the fraternal twins John "Reaper" Grimm and Dr. Samantha Grimm, a Brother–Sister Team who are the film's primary protagonists and serve as The Not-Love Interest to one another. Part of this is thanks to a combination of their actors (Karl Urban and Rosamund Pike) both being incredibly attractive and having shockingly good romantic & sexual chemistry together (with their mutual character arc of overcoming their estrangement following them having chosen different career paths being more akin to two embittered ex-spouses slowly coming back together).
  • The Halloween fandom really likes the Michael/Laurie pairing even though he wants to kill her. The 2018 reboot retcons them being related however.
  • By far the most popular pairing in the fandom for Hansel & Gretel: Witch Hunters is Hansel/Gretel. This is despite a short-"haired" witch taunting them by saying they should fornicate with each other in the film, which only disgusts them. Hansel also has a canonical female love interest not Gretel in the white witch Mina, but chemistry between their actors was rather lacking (with it coming off as the two of them being Strangled by the Red String). Add an instance of Platonic Writing, Romantic Reading with Hansel and Gretel themselves (both characters are quite physically affectionate with one another, several scenes where they show concern for the other can come across as pining, and both actors being rather attractive), and you get this.
  • After the release of the first The Hobbit film, Fili/Kili was the most popular pairing in the fandom for both brothers for a while. This died down somewhat after the next two films introduced Tauriel as Kili's love interest and Fili/Ori and Fili/Sigrid gained steam as alternative pairings for the elder Durin heir in fandom, but it's still one of the easiest Hobbit pairings to find fics for on Archive of Our Own.
    • Then with the release of the later two films, people started shipping Legolas with his father Thranduil.
  • While House of Wax (2005) starts out with Carly dating Wade, a lot of fans like the idea of pairing the fraternal twins Carly and Nick together instead. Their story plays out more like estranged lovers than estranged siblings, with Nick's blatant dislike of Wade coming across more like jealousy than just him being an overprotective sibling, one scene consisting of Nick exchanging his shirt with Carly after her's is ruined, and the twins' Sibling Rivalry-laden arguments all coming across as pretty flirtatious. What certainly helps is that they ultimately save each other's lives like a Battle Couple and some deliberate parallels are made contrasting Carly and Nick's tumultuous but ultimately positive sibling dynamic with the genuinely toxic sibling dynamic between the Big Bad set of formerly conjoined twins Bo and Vincent (who are heavily implied to have a Villainous Incest-style dynamic in at least some way).
  • In a director's-cut scene from The Lord of the Rings: 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.
  • Marvel Cinematic Universe:
    • Thor and Loki is a very popular ship; it helps that they're Not Blood Siblings (or even the same species, for that matter). It’s so heavily shipped that apparently some marketers in China failed to figure out that it wasn’t official and printed ads for one of the films with photoshop fanart of it.
    • From Avengers: Age of Ultron we have Wanda and Pietro Maximoff, following in their comic counterparts' footsteps. The fact that their actors played husband and wife in Godzilla (2014) just adds more fan video material.
    • Following the release of Black Panther, the T'Challa/Erik (T'Cherik) ship became strangely popular.
  • invoked In Pacific Rim, 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 Word of God 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.
  • In Repo! The Genetic Opera, 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 ship Luigi and Pavi (or "Pavigi").
  • Not only did a lot of Star Wars fans ship Luke and Leia back in the day, but so did a lot of merchandise, advertising, and spin-off material (most infamously Splinter of the Mind's Eye, published before The Empire Strikes Back). Nowadays, you have to look to find material for it, but it's still around; both relics of the original ship and new shippers.
  • Some fans of Stoker ship India with her Creepy Uncle Charlie in earnest. To be fair, the mutual attraction is canon.

  • The Chronicles of Narnia has Pevencest. Considering all four main characters are siblings, there really isn't a whole lot of shipping alternatives.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 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 Ship Mates. Though there's a whole lot of Peter/Edmund, too, since people love their Slash Fic. Previously the trope page image.
  • The Dresden Files 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 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 Mistaken for Gay as a couple at least once in series (which they would later use to their benefit) doesn't help matters.
  • 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 GONE fandom, and it's actually pretty popular. The ship is known as "Saine"... or "twincest".
  • A strict No Hugging, No Kissing policy during the original run of The Hardy Boys (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.
  • Harry Potter:
    • invoked Many fans think that Bellatrix Lestrange and Narcissa Malfoy (older and younger sisters respectively) fit the bill for this and have written extensive fanfics about it. Word of God confirmed that Bellatrix loves Voldemort above all else, and Harry Potter and the Cursed Child reveals that she gave birth to his daughter; some fanfics manage to get around this fact.
    • Fred and George Weasley have a veritable library of slash work dedicated to them, even though their actors are disgusted by it all.
    • Ron and his sister Ginny. Ron is quite annoyed when 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.
  • Maria Watches Over Us has Rei and Yoshino, who are canonically soeurs. The soeur relationship ranges anywhere from a Pseudo-Romantic Friendship to ambiguously romantic. Many people ship the two without even realizing that they're cousins.
  • Percy Jackson and the Olympians: 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), they get together by the end of the series.
    • Some fans pair Percy and/or Annabeth with their demigod 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.
  • A Series of Unfortunate Events had a small Violet/Klaus fandom that got quite a bit larger after the release of the movie adaptation. This is no surprise, considering they're a Brother–Sister Team who has been Promoted to Parents for their baby sister, and the two of them are pretty much the only people they can trust.
  • A Song of Ice and Fire 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 twincestuous 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 Jon's parentage is true in the books (as it is in the television adaptation), 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 Launcher of a Thousand Ships, 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.).
  • Tolkien's Legendarium:
    • The Lord of the Rings: 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 Bag Enders's "Random Slashy Interludes" for a prime example.
    • Perhaps one of the most popular pairings in The Silmarillion is Maedhros/Fingon; these two share a grandfather, Finwë. As do Celegorm and Aredhel, also paired rather often. And then there's 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... don't get along well in canon.
    • Most fanfic treats the canon Túrin/Niënor pairing as tragic, like the book in which they're the title characters — but there's fanfic.
    • As soon as the first The Hobbit 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.
  • Warrior Cats:
    • Hawkfrost/Brambleclaw, which has its own ship name: Brothershipping. They're half-brothers, which is probably the only reason it isn't banned from discussion on Warriors Wish.
    • The reveal that Firestar and Scourge are half-brothers means Altershipping also falls under this trope.

    Live-Action TV 
  • 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.
  • 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 Tommy/Thea inadvertently fell into this trope.
  • The Borgias: The most popular ship is the canonical incest of Lucrezia/Cesare. You also find Rodrigo/Lucrezia and Cesare/Juan shippers exist in abundance.
  • Buffy the Vampire Slayer: Buffy, Joyce and Dawn were insanely popular in fanfic and fanart in this respect, so much so that there were whole fansites dedicated to "Daffy" and the first rule of the 'Joyce Summers Fanfic Archive' was "No Incest" because people loved putting them together so much.
  • Chuck was 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 were given to Chuck's sister. The slightly flirty dialogue, coupled with the siblings' chemistry, made this stand out to more than one fan.
  • Dexter:
    • Dex naturally gets much shipping with his brother Brian (aka, the Ice Truck Killer), what with all the sexual symbolism the show blends with his murdering.
    • The showrunners tried to keep the 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 later divorce may have played a part) — as in Season 6, Deb starts lusting after Dexter. It helps that Dexter and Debra aren't blood-related, what with Dexter being adopted.

  • This is referred to by the 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 Little Sister Heroine—River endearing, somewhat clingy, in need of protection fairly often, and they both absolutely adore each other. Summer Glau's some things to say about the pairing (0:35); Sean Maher seemed to approve, though.
  • The Frasier fandom has some Frasier/Niles shipping, otherwise known as "Cranecest".
  • Game of Thrones: Jon Snow is shipped with both Daenerys Targaryen and Sansa Stark, both of whom he is related to. Sansa is Jon's cousin, but she was raised as his half-sister and Daenerys is Jon's aunt, but nobody — including Jon — is aware of this as nobody currently alive in the series knows of Jon's Secret Legacy, with the exception of Jon's half-brother Bran (who is Jon's cousin by blood) and Jon's best friend Sam as of the Season 7 finale. In Westeros, both matches are socially plausible: cousin marriages are considered fair game in Westeros, and the Targaryens have long since had an incest free pass, with Daenerys herself being the legitimate child of two siblings. Even on the Stark family tree, there've been at least two uncle-niece marriages. In Season 7, Jon and Daenerys develop a romantic relationship and by the finale, do it — blissfully unaware of their connection.
    • House of the Dragon:
      • Unsurprising, given that Targaryens have an exemption from the laws against incest in-universe. At the heart of this story is uncle/niece Official Couple Daemon and Rhaenyra. Some book fans who knew this began shipping them before the show even premiered. The early episodes depict them as being close and affectionate, with a few Ship Tease moments, so by the time the fourth episode rolled around and their overt interest in each other was confirmed, people were already shipping them.
      • Alicent/Rhaenyra technically qualify, since Alicent is Rhaenyra's stepmother (although most shippers wish she wasn't, not just to promote their ship, but because this marriage kind of ruined Alicent's life).
      • Full blooded siblings Aemond/Helaena started getting some attention after Aemond defends her to Aegon, even suggesting that he wishes Helaena was bethroted to him rather than to Aegon. The fact that it's Aemond who watches Helaena and Jace dancing like a hawk rather than her husband Aegon added fuel to the shipping fire.
      • The aforementioned aunt/nephew pairing of Helaena and Jacaerys has also picked up a few supporters after their dancing scene. It helps that earlier Rhaenyra did propose an engagement between the two, which could've potentially healed the divide between the Blacks and the Greens. It's generally agreed upon that Nice Guy Jace would've been a much better husband to Helaena than Aegon because of her special neurodivergent needs.
  • 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 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 faces mere inches apart.
  • Heroes:
    • Maya and Alejandro Herrera are twins who seem to be a little too close to each other; even their powers require a 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's first meeting could've easily been seen as a sweet little Meet Cute mixed with a Rescue Romance set-up, and even after their blood relation was revealed, they still seem to be closer than one would expect of an uncle and niece. Really, the Abandon Shipping for this pair was pretty minuscule even after that little revelation. The chemistry between the actors didn't help, especially since Milo and Hayden briefly dated in real life.
    • Claire is reunited with her long lost biological father Nathan, sharing a hotel room with him and getting drunk together in the classic Genetic Sexual Attraction scenario.
  • When Home and Away 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.
  • It's Always Sunny in Philadelphia:
    • Twins Dennis and Dee Reynolds, due to the large amount of Incest Subtext between them (which included 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 Pet the Dog moments towards her; Dee herself doesn't vocally reciprocate it, but she is shown to 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 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.
  • Quite common in Kamen Rider series. Especially Kamen Rider Kiva and its many bathing scenes. However, "Kivacest" typically refers not to Wataru and Otoya, despite their epic Time Travel-enabled bath scene (with back scrubbing!), but to Wataru and Taiga, who turns out to be his brother.
  • Kirby Buckets and "Bucketcest", which is what you get when you pair the title character with sister Dawn.
  • Lab Rats: Shipping the Davenport siblings with each other is highly popular, especially Bree and Chase. Fanfic writers tend to portray them as not actually being biologically related.
  • The Life with Derek fandom give us the step-siblings Derek and Casey (a.k.a. "Dasey"). Their antagonistic Sibling Rivalry frequently comes across as Belligerent Sexual Tension, which in turn causes their moments of genuine kindness and friendship to present them both as Flirty Stepsiblings who are in deep denial about their attraction towards one another. "Dasey" is by far the Fan-Preferred Couple for the series' fandom, and even years after the series has ended, both Michael Seater and Ashley Leggat are still huge Derek/Casey shippers. Hilariously enough, Seater and Leggat even acted out a Dasey fanfiction for a podcast back in the day.
  • Don/Charlie or "Eppescest" is a notable ship in NUMB3RS fandom, especially in its earlier seasons when there was a greater emphasis on the two reconnecting as adults.
  • Once Upon a Time: One of the most popular (if not the most popular) ships in the fandom is that of Emma Swan and Regina Mills (aka the Evil Queen), who, while not related by blood, are related by marriage (Regina is the stepmother of Emma's mother, Snow White). This fact is often ignored by their shippers, and those who don't will justify it by saying that since they aren't blood relations, it's okay. Some write it in as a joke in their fanfic, but still ultimately brush past it and get to the romance.
  • Orphan Black: Ubiquitous in the fandom, given the large number of characters in the show who are clone-sisters or clone-brothers, many of whom only became aware of one anothers' existence as adults, so no worries about the Westermarck Effect. (The series also has a canon emotionally, if not genetically, incestuous relationship between Susan and Ira.)
  • 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 case of Platonic Writing, Romantic Reading have also happened since they have a lot of Belligerent Sexual Tension that turns into UST later. They also have their fair share of heartwarming moments.
  • Riverdale:
    • The Blossom twins, Jason and Cheryl, get this from fans. It doesn't help that one of the writers is behind Afterlife with Archie, 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 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.
  • More than a few people have mistaken Zelda and Hilda from Sabrina the Teenage Witch 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.
  • In the fandom for the American adapatation of Shameless, Gallaghercest is rather popular. Fiona/Lip is probably the most popular ship, helped by how they are, in-universe, the parental figures of their four younger siblings, being that their mother has been gone for some time and they eventually kick their deadbeat father out of the house. Although each has a respective love interest, Fiona quickly loses interest in hers and she tends to be heavily disapproving of Lip's love interests in what could easily be interpreted as jealousy.
  • Skins
  • Shipping Kara with her adopted sister Alex is one of the most popular Supergirl (2015) 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.
  • Supernatural:
    • The Wincest shippers see this between brothers Sam and Dean Winchester, in part due to how much sheer chemistry their actors have, and the existing Incest Subtext in canon. During the early seasons, it was unquestionably the most popular pairing in the fandom.note  Although it lost its status as Fan-Preferred Couple to Dean/Castiel, it's still the second most popular ship by a significant margin and the most popular ship for Sam. In-Universe, however, Sam and Dean react to Incest Yay Shipping with the expected amount of Squick.
      Dean: They know we're brothers, right?
      Sam: Doesn't seem to matter.
      [Six seasons later]
      Dean: You know they're brothers, right?
      Marie: Well duh. But... subtext.
    • 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 Michael/Lucifer, because it mirrors the Winchester pairing, and occasionally overlaps with Wincest when Sam serves as Lucifer's vessel, and Dean for Michael.
    • Some people ship Castiel/Claire Novak. He may not technically be her father, but he uses her father's body and looks just like him.
  • "Thundercest", the shipping of Phoebe and Max by fans of The Thundermans. It has gotten so bad that Kira Kosarin, Phoebe's actress, has spoken out against it.
  • There's a huge and passionate faction of Klaus/Rebekah shippers in The Vampire Diaries and later The Originals 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.
  • The Waltons, 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 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 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.
  • 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 by cuckolding Henry, he will cost him political support. After Anne's death, he and Elizabeth actually do the nasty, though.
  • Justin and Alex in Wizards of Waverly Place are the Fan-Preferred Couple, to the point where the pairing used to have a separate Incest Yay page back when this wiki still had a Fetish Fuel section until it was sent here.
  • Bates Motel, a prequel to the film Psycho, has its share of fans who ship Norman and his mother Norma, with the pairing often referred to as "Soulbates" on social media. It's less of a case of fans reading their own fetish into a work and more of a case of the show deliberately playing with it as a source of dramatic tension and teasing it with highly sexualized marketing. In the show, Norman and Norma relate to each other more like a married couple than a parent and child. Despite the fact that Norman is almost an adult, throughout the series the two holds hands, he helps her get dressed, they kiss on the lips, sleep in the same bed and spoon together. They become intensely jealous whenever the other becomes involved with another romantic interest, manipulate each others emotions to get their way and generally exhibit an unhealthy, all-consuming codependency.

  • Natasha, Pierre, and the Great Comet of 1812:
    • Sonya/Natasha is a pretty vocal ship in the fandom, despite the fact that they're cousins. To be fair, at least some of the shippers don't seem to realize/remember they're family; their relation is only mentioned in passing twice at the start of the show. If you listened to the song "Sonya Alone" out of context, you could easily make the mistake of assuming they have a Pseudo-Romantic Friendship instead of a close familial bond.
    • Anatole and Hélène are siblings, and everyone in the fandom absolutely knows this; it's just that a lot of them don't care. This one actually has canon support; they get way too touchy-feely and comment on each other's attractiveness more than once, Pierre makes a dig at Anatole implying he thinks/knows something is going on, and Anatole's character bio in the program has him admit he often wishes Hélène wasn't his sister. Given that they get along fine and seem to be close, you have to wonder what the reason for that is... The subtext was present in the source material, too, leading some fans to declare "we have Tolstoy on our side!"
  • Richard II (particularly as presented in The Hollow Crown and/or the RSC version starring David Tennant) has Richard/Bolingbroke, as well as Richard/Aumerle (who share a lengthy kiss in the RSC version), all cousins. (Specific to the Hollow Crown version of Henry IV, Part 1, the sight of Jeremy Irons slapping Tom Hiddleston caused a few fandom ripples.

    Video Games 
  • BioShock Infinite:
    • It's near impossible to find a Lutece fan who doesn't ship them together. In fairness they're not really siblings, but Screw Yourself isn't much better.
    • Booker and Elizabeth have an enormous fandom despite the whole father and daughter thing that was kind of an important revelation.
  • BlazBlue:
    • Brothers Ragna the Bloodedge and Jin Kisaragi are possibly the most popular yaoi pairing, and doubly supported by the two's fierce rivalry. What really sells it is Jin's rather unhealthy obsession with killing Ragna, and the creators' tendency to play with it in the various Gag Reels.
    • Ragna and Noel Vermillion, whose fandom weren't impeded at all by the revelation Noel is a clone of Ragna and Jin's sister Saya.
    • Ragna/Nu (who is also a clone, like Noel). Nu is a full blown Yandere for Ragna, and all of her interactions with him have very overt overtones.
  • Magus and Schala of Chrono Trigger are often a target of this by some fanfic writers, building off of some perceived implication that the siblings were attracted to each other when they lived in Zeal. Note that Magus was about 9 or 10 at the time, while Schala was in her late teens.
  • Cuphead and his pal Mugman are occasionally interpreted as this. Whether this also qualifies as a Toy Ship depends on how you interpret the clashing definitions of their Vague Ageelaboration .
  • Dead or Alive 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.
  • In Devil Survivor, 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 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.
  • Hawke/Bethany has a surprisingly strong following in Dragon Age II. 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.
  • Fraternal twins Anna and Mihael in Dragon Valor.
  • Far Cry 5: There are fans who ship at least two of the three Seed brothers together, or even as a One True Threesome. The most popular seems to be John/Joseph, as John is shown to be highly obsessed with and clingy towards Joseph.
  • While it's likely that some degree of Incest Subtext was intentional in Fatal Frame II, especially when it comes to Mio and Mayu, the latter being portrayed in the remake as more or less being a yandere for for the former, all the twins in the game get shipped to some extent. Itsuki and Mutsuki are an especially popular pair, as their Crimson Sacrifice Ritual failed apparently due to there being too much love between them.
  • Final Fantasy:
    • Faris/Lenna from Final Fantasy V has some popularity. The general interpretation for this pairing is that Faris's Big Brother Instinctnote  towards Lenna is actually romantic interest.
    • From FFX-2 we have Yuna and Rikku. There's canon Incest Subtext - Brother towards his cousin Yuna - but exploring it is not particularly popular.
    • Due to the nature of "Subtle Romance" of Final Fantasy XII, some fans decided to assume that Basch has no eyes for anyone but his twin brother Noah/Gabranth and vice versa.
    • And in Final Fantasy XIII, there is Lightning and Serah.
  • Fire Emblem:
    • The king and queen of this trope would be half-siblings Eldigan and Lachesis, while the prince and princess would be fraternal twins Eirika and Ephraim.
    • The romance system in Fire Emblem: Genealogy of the Holy War allows for Kissing Cousins, of which two pairings are actually half-sibling incestnote .
    • The romance system in Fire Emblem: Awakening allows for cousin marriages as well, although the NA/PAL releases Bowdlerized this slightly by referring to such pairings as "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 Robin and the other with Morgan.
    • Fire Emblem Fates:
      • It seems the most popular pairings involve pairing Corrin with his/her relatives (to be fair, the Nohrian siblings are adoptive, and the Hoshidan siblings are all revealed to be adoptive as well). For example, Female!Corrin is commonly shipped with her adoptive brothers Xander and Leo, and with her actual brother Takumi (while they're actually Not Blood Related, they think they are until their S-Support). Meanwhile, Male!Corrin is commonly shipped with his adopted sister Camilla and Azura, who looks to not be related to him but is actually 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.
  • Golden Sun:
    • The most obvious is Felix and Jenna, who are siblings (and appropriately dubbed "Oopsie-shipping" by the fans).
    • Fans also like to pair up 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 Surprise Incest.
    • A 4koma doujinshi, Golden Sun Gag Battle, has Ivan trying out his new Reveal power on Hama and Feizhi's clothes. To be fair, Gag Battle was published before The Lost Age outed Hama as Ivan's sister, making this a rather meta case of Surprise Incest.
    • Golden Sun: Dark Dawn 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 Amiti is fair game... and, technically speaking, a distant enough relationship to be legal even by American standards.
  • GreedFall has the protagonist De Sardet and their cousin and childhood friend Constantin D'Orsay. Constantin cannot be romanced and is strictly a Guest-Star Party Member, but De Sardet is repeatedly shown to be the most important person to him, and after he pulls a Face–Heel Turn, De Sardet can accept his We Can Rule Together offer. The fact that De Sardet turns out to be adopted likely helps too. As a result, a not insignificant part of fandom latched onto the ship and the relationship was given a Fandom Nod in the DLC episode.
  • The popular and fan-preferred pairing of the Playable Character (sometimes called Knight or Ghost) and Hornet from Hollow Knight. Might veer into this, because they may or may not be siblings because of their nature.
  • A small subset of Life Is Strange 2 ship Sean & Daniel Diaz, due to the game's heavy focus on their close relationship. Others avoid it, not necessarily due to the incest, but due to their age gap (Sean is sixteen, Daniel is nine).
  • Rock and Roll (or Mega Man and Roll in the West), whose actual connection varies in their various incarnations. The same applies to Rock and Blues (Mega Man and Proto Man in the west).
  • Metal Gear: 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 Truly Single Parent.
  • Mari/Sunny is relatively popular in the OMORI fandom, as well as Hero/Kel, although Sunny is more commonly shipped with Basil or Aubrey.
  • Onmyōji has this going on between Kuromujō and Shiromujō thanks to the former's huge Big Brother Instinct and the (amnesiac) latter's stating that he has some sort of feelings toward Kuromujō in his in-game autobiography.
  • Pokémon:
    • 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.
    • Lusamine from Pokémon Sun and Moon sometimes gets shipped with her children Gladion and Lillie. Her children getting shipped together isn't unheard of, either.
  • Alfred and Alexia Ashford in Resident Evil – Code: Veronica. A case where the Incest Subtext may have been intentional from the developers' part.
  • Shadow The Hedgehog and Maria Robotnik from Sonic the Hedgehog 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.
  • The "Squid Sisters", Callie and Marie, from Splatoon get shipped a lot. It helps that they are actually cousins, which makes it more acceptable to varying degrees.
  • Too much to count from Summertime Saga. While all incest storylines, of which there are many, were (officially) removed from the game in later updates, players continue to ship them. This even extends to characters who've never shown any canon interest in each other, such as Mia and her dad.
  • Super Mario Bros.:
    • The Mario Bros. themselves have quite a few shippers. The reasons given vary from them being among the very few human males in the canon that aren't outright Gonks, to their canonically very close sibling-like friendship; living together well into adulthood, also doing most activities together out of the house, a tendency for Man Hugs especially in the Mario & Luigi series, and most of Luigi's lines about or aimed at Mario throughout the series being full of open admiration.
    • Nintendo can't make up their minds about whether Toad and Toadette are siblings, friends, or what. As a result, it is hard to tell how many of their shippers are unaware that they could be relatives, and how many that consider this possibility another reason to ship them.
  • The Tale of Food: That there are siblings and parents but no such thing as biological relation among the foodsouls as they don't reproduce only adds fuel to the incest shipping fire. One of the major ships in this fandom is Dézhōu × Ah-Fú.
  • In Tales of Symphonia, Kratos and Lloyd seemed awful subtexty to a lot of people. Some of them didn't Abandon Ship after it was revealed that Kratos is actually Lloyd's real father.
  • Tales of Xillia 2:
    • One of the protagonist Ludger Kresnik's most popular ships is with Julius, his brother, termed as "Kresnikcest" after their surname. Adding layers to the incest is that Julius raised Ludger since the latter was five years old and they are also first cousins, sharing the same father with their mothers being sisters.
    • Rarer is shipping either brother with their father, Bisley Bakur, though it doesn't use the same ship name and tends to be Played for Horror.
  • In the Touhou Project 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. That said, shipping the Aki sisters with each other may simply be because they have such a small fandom and they don't have enough character interactions (or even potential for interactions) to get shipped with anyone else.
  • Touken Ranbu: Though the phenomenon of siblings in this game doesn't have a 100% concrete rule behind it since the characters are personified inanimate objects, the rule of thumb is that swords forged by the same smith are almost always brothers. With that in mind:
    • Swords forged by Awataguchi Yoshimitsu get shipped with each other a lot, with the most frequent being Ichigo Hitofuri with any of his younger brothers and Namazuo and Honebami with each other.
    • Swords in the Sanjō school, as in all of them as they were all forged by one person, if viewed under the rule of thumb above. Examples include Mikazuki/Kogitsunemaru and Iwatōshi/Imanotsurugi.
    • Hachisuka and Nagasone Kotetsu, who are adoptive brothers.
    • Kasen and Izuminokami Kanesada, while not forged by the same person, have the same surname and belong to the same school. Their ship is nearly as big as massively popular Izuminokami/Horikawa.
  • Twisted Wonderland:
    • Jade and Floyd Leech are a popular Twincest ship, especially within the Japanese fandom. It doesn't help that both twins are somewhat wild and mischievous, or that Jade is known to spoil Floyd and indulge his childish behaviour due to wanting Floyd's happiness more than anything.
    • While almost entirely within the Japanese fandom, Leona is sometimes shipped with his young nephew Cheka, as Cheka adores him as a Cool Uncle and demands his attention despite Leona being less than fond of him. However, due to Squick implications arising from Cheka's age (plus child pornography being banned on sites like pixiv), most doujin, fanarts and fics for this ship drastically age him up or are set in the future.
    • Leona has also been shipped with older brother Falena, who's never appeared in the present and doesn't even have a design.
    • Lilia has been shipped with Malleus, Silver and/or Sebek, all his godsons.
  • Undertale:

    Visual Novels 
  • Ace Attorney caters to this trope in various ways: there's shippers for Mia/Maya, Lana/Ema, Jake/Neil, Edgeworth×Franziska (who are adoptive siblings), and even 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 Dahlia/Iris, from Trials and Tribulations and Kristoph/Klavier, from Apollo Justice. To be fair, many fans shipped Apollo and Trucy before they knew they were siblings, and they themselves never find this out.
  • In Danganronpa: Trigger Happy Havoc, Junko Enoshima/Mukuro Ikusaba is a rather popular ship, which is nicknamed "Despaircest". Danganronpa: Trigger Happy Havoc IF and Danganronpa 3: The End of Hope's Peak High School upgrade this to one-sided Incest Subtext, especially in Danganronpa 3 where Junko slaps Mukuro on her ass, knocking her to the ground, and then stomps and pushes on a very specific spot from behind at Mukuro blushes, looking quite pleased.
  • Higurashi: When They Cry:
    • Rika and Hanyuu are one of the most shipped Rika pairings. It helps that they're very distant relatives as Hanyuu died centuries ago.
    • Pairing the twins Shion and Mion is relatively common. Going by Pixiv tag results, it's their first and second most popular pairing respectively in Japan regarding fanart. 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.
  • It's not uncommon for Morenatsu fans to ship Tatsuki with his father Tappei, even though no official route involves this happening.
  • Umineko: When They Cry also gets a lot of this, not least of which because a majority of the cast is related, and three canon ships (George/Shannon, Jessica/Kanon, and Battler/Beatrice) are all Surprise Incest

  • Since Jay Naylor's webcomic Better Days contained actual Twincest, readers have been joking about something similar happening on its sequel Original Life ever since it got started. Early in the series, there were definite undertones of BST between Janie and a cousin.
  • Ennead: It's a comic about Egyptian mythology, so this trope is practically a given. The most prevalent ships in the fandom are Seth/Horus (who are uncle and nephew) and Osiris/Seth (who are brothers). Nephthys/Isis (sisters) has a fair following as well.
  • Homestuck:
    • John/Jade and Dave/Rose (especially the latter) are confirmed ecto-siblings with rather large shipping bases.
    • The amount of Bro/Dave shipping is unsettling when you find out that Bro is not only Dave's brother, but also Dave's ecto-father. According to Google Trends, "Stridercest" (Dave/Bro, or sometimes Dave/Dirk) got much more popular after Act 6 began, which was when the post-Scratch versions of the Guardians were introduced.
  • Tower of God: On the rare occasion that the person Khun Aguero Agnis is shipped with isn't Bam, then it'll likely be Maria, who's his half sister. This is likely to do with the In-Universe rumors that have yet to be confirmed or denied, as well as a... mildly suggestive sketch of the two that the author posted on his blog, with Maria standing in a door way and Khun getting dressed over an unmade bed. (He later had to clarify that Maria was telling Khun to hurry up as he was preparing for a banquet, and that Khun was a virgin.)

    Web Original 
  • Button's Adventures: If Button Mash is not being paired up with Sweetie Belle the he is definitely being paired with his mom, Cream Heart. Taking into account how the Brony fandom reacted to her, is understandable why.
  • In Cinnamon Bunzuh!, an Animorphs Review Blog, reviewer Ifi ships Ax and Tobias (who are uncle and nephew) while the latter is morphed into the former.
  • Shifty/Lifty is a pretty common pairing in the homosexual or Yaoi crowd in Happy Tree Friends.
  • RWBY:
    • In a poll of 817 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 (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 infamous "Entire Team" ship (Summer/Taiyang/Raven/Qrow) contains Raven and Qrow, who are twin sister and brother. Most supporters interpret it as "Taiyang Really Gets Around" to avoid the problem, but a full-on STRQ orgy isn't unheard of.
    • Ruby and her Cool Uncle Qrow together is one of the more popular incestous couples in the fandom. This is likely attributed to the fact they're not blood related (Qrow is the biological uncle of Ruby's half-sister, Yang, but not Ruby herself).
    • Yet another fan-favorite pairing matched Weiss with her older sister Winter, primarily because until Volumes 7 and 8, Winter was the only person in her family that Weiss had any positive relationship with.
  • Lenny and Elizabeth Priestly of Survival of the Fittest v3 are seen by most handlers as having an... 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).

    Western Animation 
  • Lemongrab and his clone, Lemongrab 2, from Adventure Time 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.
  • The Amazing World of Gumball has Gumball mostly being shipped with his family especially his adoptive brother Darwin and his mother Nicole. Although other members of the Watterson family aren't excempt, even Nicole's own parents too. The former is referenced in "The Shippening," in which Sarah draws a genderbent, human Gumball marrying a human Darwin, which comes to life. However, Gumball being paired up with his mother, especially in Rule 34 art is so abundant, it can reach Fan-Preferred Pairing levels.
  • American Dad!:
    • Steve Smith is often shipped with Francine (his mother) and Hayley (his sister). It doesn't help that he has canonically expressed incestuous attraction to both of them.
    • Hayley is sometimes shipped with her father Stan. Similar to Steve, there are some implications that she has incestuous feelings for Stan (she once dated a man who looks and sounds exactly like Stan) and the episode "The Kidney Stays in the Picture" reveals that Stan might not be Hayley's biological father.
  • Occurs in some segments of the Animaniacs fandom, though probably more because there aren't very many other shipping options.
  • Avatar: The Last Airbender:
    • 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 just about everyone.
    • A lot of people give Zuko an Oedipus Complex, especially after The Search, often with the idea that their familial affection doesn't overpower any sexual attraction due to years of separation.
  • Cousins Ben and Gwen from Ben 10, thanks to many Aw, Look! They Really Do Love Each Other moments and meeting many of the requirements for Belligerent Sexual Tension. Indeed, the pairing is so popular that it's widely speculated that getting Strangled by the Red String (with Julie and Kevin, respectively) in the first Sequel Series was an attempt at Ship Sinking.
  • Brothers Huey and Riley from The Boondocks 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.
  • For Dexter's Laboratory fans, Dexter and his mother are the subject of much Rule 34 art. Same with Dexter and Dee Dee, though it appears less frequently than Dexter and his mother.
  • The DuckTales (2017) fandom's ships between Webby and the triplets became a borderline example as of the series finale, where Webby is revealed to be the daughter of their great-uncle Scrooge McDuck and, thus, their first cousin once removed. Their hometown Duckburg is located in the United States, where this relationship is not even considered incestuous in 44 of the 50 states.
  • Gravity Falls: The Pines family has not one, but two pairs of rather widely shipped twins.
    • "Pinecest" refers to the Dipper/Mabel pairing. Being Polar Opposite Twins, they're a Brother–Sister Team who have a dynamic similar to a Savvy Guy, Energetic Girl romance, and they are The Not-Love Interest for each other (frequently sacrificing for/defending one another); Mabel's Abhorrent Admirer Gideon even sees Dipper as "coming between" him and Mabel's happiness and tries to Murder the Hypotenuse. Their Grunkle Stan also outright claims it's "unnatural" for siblings to get along as well as Dipper and Mabel do. The twins are also Heterosexual Life-Partners and True Companions (to the point where Mabel basically has a mental breakdown in the lead-up to the Series Finale when she learns that her brother is planning on staying in Gravity Falls instead of coming home with her when the summer ends), and they are basically each other's best friends. Dipper and Mabel also share a bedroom and are pretty physically affectionate with one another (i.e., just try to count the number of times Dipper and Mabel either hold hands or pull the other out of the way of danger in only a single episode). Perhaps the clearest example of the unintentional Ship Tease between the Mystery Twins is in the series' penultimate episode, where Dipper's Rousing Speech to Mabel urging her to come with him out of Mabeland and grow up with him sounds pretty similar to a Love Confession of the romantic variety, and for a brief moment the two twins even look like they're about to kiss before they instead perform a "sincere sibling hug" as a Platonic Declaration of Love. They're so established in fandom they have a {{Recurring Fanon|Character} Fan-Created Offspring, a daughter named Cassie (short for Cassiopeia),
      • invoked Series creator Alex Hirsch has poked fun at it on the official Gravi-Team Falls Tumblr. His Squicked-out reaction is also pretty understandable considering how Dipper and Mabel are based on him and his own twin sister, Ariel.
        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 Grunkle Stan has a twin, they received similar treatment, with their ship name being "Stancest".
  • While the Dib/Gaz ship isn't as popular as the Dib/Zim ship in the Invader Zim fandom. It still has quite a bit of fans, with most lewd art of this ship, mostly having the two be aged-up and given a heaping dose of Self-Fanservice, especially Gaz. Whom is usually portrayed as a busty and curvy Goth Gamer Girl. It even has a dedicated motor that helps the ship running, for those who do like the pairing.note 
  • The Legend of Korra:
    • 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 tangle, but not always.
    • Tarrlok and Amon/Noatak became very popular after the season 1 finale, thanks to the buckets and buckets of angst. Who cares if they both died? That's what Fix Fics are for.
    • Desna and Eska are a pair of Creepy Twins, 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 There Is Only One Bed in their hotel suite, though Desna apparently sleeps in the bathtub.
    • Tenzin's daughter, Jinora, is the center of multiple fan pairings: including with her kid sister, Ikki, and the 14 year old version of her grandmother, Katara. Most often seen in H-art.
  • My Little Pony: Friendship Is Magic:
    • Not only were Twilight Sparkle and her brother Shining Armor very close when they were younger, but people have noted that one of the few males who Twilight has ever shown attraction to on screen has the same hair colour and profession as her brother. Shining Armor is also introduced in the episode where he is getting married, and Twilight takes the news... poorly.
    • Though the exact nature of their relationship was ambiguous for most of the show's run, Spike being revealed as Twilight's adopted brother in latter seasons has turned that pairing into this.
    • One Wild Mass Guess was that Applebloom is the daughter of Applejack and Big Macintosh instead of their sister. This was 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 and Granny Smith).
    • Celestia/Luna, a.k.a. "Princest", is the third most popular ship involving the princessesnote . Granted, they're goddesses—incest is pretty common no matter what pantheon you're looking at. 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 (sort of) appearance, despite the fact that they may or may not be cousins, albeit distant ones.note . It even turned up in one of the show's Christmas specials, where Marble stumbles upon Big Mac and Sugar Belle nuzzling affectionately, and immediately cringes and looks heartbroken.
    • 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 Opposites Attract.
    • Due to her parents being super fans of her, fans have shipped Rainbow Dash with both of them.
  • The Loud House: Taken up to eleven (no pun intended) with Loudcest, which has fans shipping Lincoln with any or all of his ten sisters crazier than the Jaime and Cersei Lannister shipping. Even Lily, a baby, is not safe. 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, their genderbent counterparts from the mirror universe, or Lincoln's Gender Bender self Linka from that universe either. Lincoln and Lynn together is the most popular pair, to the point where it goes head-to-head with Lincoln and his canon love interest Ronnie.
  • Even though they're siblings, Miles and Loretta on Miles from Tomorrowland tend to be shipped a lot in fan art and fan fiction, interpreting their intimate moments as Belligerent Sexual Tension. The fact that they're the only members of the family to be on Mission Force One in season 3 adds to this.
  • It's been a common joke that the Wonder Twins are incestuous. This was referenced to in one of the The New Adventures of the Wonder Twins shorts by [adult swim], where Marvin mistakes them for watching porn together.
  • Phineas and Ferb:
    • 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. "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.
  • The Powerpuff Girls:
    • The most popular ship for Blossom, besides her and her Spear Counterpart Brick, is her and Mojo Jojo (which is also Foe Yay Shipping). Mojo was raised by Blossom's father and he was the one who accidentally created the girls, so depending on who you ask Mojo Jojo is either Blossom's older brother or her second father.
    • Considering the lack of characters to ship, the titular triplets get shipped in various combinations more than any other Les Yay pairing.
    • The Rowdyruff Boys can be seen as related to the Powerpuff Girls. They're Spear Counterparts who were raised by Mojo Jojo, who is more-or-less related to the Powerpuff Girls himself.
  • A in a rare adoptive family example, Riley and her adoptive mother, Agent K Daring of Disney's The Replacements are often shipped.
  • Rick and Morty
    • A fair amount of Rick/Morty fanfiction exists for some inexplicable reason. It might be a result of the original video, where "Doc" repeatedly asked "Mharti" to give him a blowjob, or the fact that they showered together in the show. But then again, "Doc" wasn't "Mharti's" grandfather in the original video (as far as we know), and the nudity thing was a result of avoiding nudity-squeamish aliens. Roiland himself has even stated that due to the nature of the series, there may indeed exist a timeline where Rick and Morty are in a loving relationship. The face-huggers that fall in love while possessing Rick and Morty's bodies in "Promortyus" may be the closest thing so far.
    • Alongside that, Morty/Summer isn't far behind when it comes to incestuous pairings. Becomes borderline canon in a completely bizarre way as of "Rickdependence Spray", in which they accidentally conceive a son together as a result of Morty's giant rampaging sperm inseminating one of Summer's enlarged eggs.
  • In Robotboy, pairing the titular character with Robotgirl is pretty much Brother–Sister Incest, if we take in account the "robots with the same creator=siblings" rule. It's worth noting, though, that Robotgirl is never referred as "sister", only "friend", and Moshimo intended her to be a "companion" to Robotboy. Maybe the ship exists because Robotboy's previous crush was Mona Lethal...
  • In Rugrats and All Grown Up!, some people ship step-siblings Chuckie and Kimi together. On the other hand, Phil and Lil probably have more shippers and they're twins.
  • Papa Smurf and Smurfette in The Smurfs, while not biologically related, get constantly shipped together in this fashion. It doesn't really help that Papa Smurf even has that type of interest in Smurfette. This is fortunately averted in Sony Pictures' The Smurfs film series, as Papa Smurf treats Smurfette like a daughter.
  • A lot of Sofia the First shipping involves pairing Sofia with either of her step-siblings, Amber or James.
  • The Star Wars: The Clone Wars fandom has many minor "Clonecest" ships, or romantic pairings between two or more Clone Troopers, all of whom are clones of the same man, and thus genetically identical twins. The most common ones are Cody/Rex (who already have a close friendship in canon) and Boil/Waxer. It's worth noting that being fully engineered soldiers from birth, none of the Clone Troopers were raised in any way resembling traditional family dynamics and may never have been exposed to them even after deployment into the wider galaxy, and thus it's unlikely that they even see each other the way normal siblings raised together do.
  • The Twins from 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 porn incident that traumatized them has been used by supporters and detractors of the ship to prove or disprove the dynamic being canon.
  • Unsurprisingly, in Unikitty! show, many fans pair up Unikitty with her little brother Puppycorn.
  • Most We Bare Bears ships are between the bears, as there 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.
  • Yin and Yang from Yin Yang Yo! have a lot of this going on, especially since they're, you know, opposites.

Alternative Title(s): Incest Yay
