History BrotherSisterIncest / WesternAnimation

** Actually if you see the scene carefully Hayley is more surprised than repulsed: As Steve begin to make out with her she put her hands on Steve's shoulders but don't push him away, by the time kiss finish (on Steve's terms) she has her arms down.

*** Apart from this song, I see no signs of any over-brother-and-sisterly interest coming from Phineas. He's just as nice to Candace as he is to everyone else. But Candace's obsession with busting her brothers might seem a little... odd.

*** True, but they were singing in character, and if Candace hadn't been the 100th contestant it would have been some other person.

-->'''Nelson:''': [[GetARoom Get a room you two!]]

-->'''Bart:''' A little is not gonna be enough honey pay.
-->'''Lisa:''' Don't call me "honey pay".

* Astute viewers may pick up something weird about Martin's relationship with his stepsister Diana in ''MartinMystery''. Turns out, in the original Italian graphic novel, they were lovers. In the original comic they are not related, and even marry. Case of AdaptationDecay.

** And in the movie, Lois complains to Peter that, with Chris and Meg around, they have no privacy at all and asks if they shouldn't be dating by now. Of course Peter assumes [[CompletelyMissingThePoint she meant dating each other]].

* Despite its Western origins, the writers of ''AvatarTheLastAirbender'' seem to be playing with this trope. One of the panels during their Shipping Slideshow at Comic Con 2006 [[CrackPairing romantically paired]] Princess Azula with Prince Zuko's [[SecretIdentity alter ego]], the Blue Spirit. Azula plays the proverbial [[TheVamp Temptress]], seductively luring her brother back to the dark side in the second season finale. Then of course came a certain bedroom scene in the season 3 premiere...

* The titular characters from ''TwinsOfDestiny'' had this implied, through their interaction throughout the series but mostly their decision in the final episode to leave everyone else and everything they have bonds with behind to be together. Just for the record: Jules and Julie both have a different set of parents, but their mothers are implied to have been incarnations of the Moon Goddess. Their mothers died during the twins' birth and their fathers were taken prisoner by the Empress of China, who wanted the twins dead. Jules and Julie were smuggled out of the country and brought to France, where they were raised by one man as siblings until they were about 14 years old. They know they aren't biologically related, but they do consider themselves siblings, often referring to the other with "my brother" or "my sister".

* In an odd case of Brother/Brother incest, Daggett and Norbert of ''AngryBeavers'' are often shipped. However, since this fact is rarely touched upon in the series (the only example I can think of is the first episode) this may be accidental.

* Anyone get this vibe from Danny and Jazz, from ''DannyPhantom''?
** No.
*** Danny and Jazz? A little. ''[[FutureMeScaresMe Dan]]'' and Jazz? Definitely.

** In the episode "Halloween on Spooner Street",Meg and Chris in costume make out in a dark closet not knowing who the other is until the door is open,they try to make light of it later,it's implied they did a lot more than kiss and also Chris knew what costume Meg was wearing but being Chris he may have forgotten.

** And then there's the Bart/Lisa shippers. Yes, [[{{Squick}} they exist]].

-->'''Lisa:''' I gonna do a little research
-->'''Bart:''' A little is not gonna be enough honey pay
-->'''Lisa:''' Don't call me "honey pay"
-->'''Bart:''' You got it tootsie pop

-->'''Lisa:''' We are Brother and sister
-->'''Milhouse:''' So are my Parents... I think.

*** While Jackal's disgust for Hyena's robophilia is fact, there's no actual evidence that his reasons for this are anything more than the normal reaction to discovering your sister likes to [[hump toasters.]] There's nothing in canon or Word of God to suggest there was a love triangle at all- especially since Coyote wasn't interested in Hyena, either.

* Astute viewers may pick up something weird about Martin and Diana's (his step-sister) relationship in ''MartinMystery''. Turns out, in the original Italian graphic novel, they were lovers. In the original comic they are not related, and even marry. Case of AdaptationDecay.

** "Something weird is going on" is that Optimus had forgotten who his creator was so it's more surprise that he's learned Alpha is his dead beat dad. Also Elita was leaning in for a kiss so it may be more "hero denying his pleasures" than anything else. Also two reasons he denied her: [[MoralGuardian parents' anger]] at robots kissing and kids's reaction to seeing a parental (albiet fictional) figure smooching other than a quick peck on the cheek.

* In ''AmericanDad'', Roger tricks Steve into believing he's adopted. This triggers a bit of a HeroicBSOD in Steve and one of the first things he does is go to his sister Hayley, says there's always been "sexual tension" between then makes out with her. Hayley is understandably surprised and repulsed.

* Aversion: With the communal raising of children the titular species employs in ''{{Gargoyles}}'', this was an early fan idea about Demona's and Goliath's relationship, until WordOfGod severerly beat that out the fandom by stating that the pheromones a gargoyle releases when he is courting smell horrible to any close family relation. This is only natural, really, since nature prefers genetic diversity over in-breeding.

** Jackal from "Gargoyles" is a {{Complete Monster}} who, along with his sister Hyena, is one of the most ridiculously {{Ax Crazy}} characters in the Disney canon. However, when Hyena falls in love with {{Humongous Mecha}} Coyote, he seems to find it a little more reprehensible than just a normal big brother would, especially considering it's nothing worse than what he's done, and comes off much more as a jealous {{Stalker with a crush}}. He later got most of his body replaced with cyborg parts, and they end up in a pretty sick love triangle for most of the series.

**** In the original yes, but in the extended version there's some serious innuendo, not just in the added lyrics but in the looks they give each other too.

*** Apart from this song, I see no signs of any over-brother-and-sisterly interest coming from Phineas. He's just as nice to Candace as to everyone else. But Candace's obsession with busting her brothers might seem a little... odd.

* In [[TransformersGeneration1 G1 Transformers]], Orion Pax and Ariel were originally boyfriend and girlfriend. After their bodies were destroyed, Alpha Trion recreated them both as Optimus Prime and Elita One and the two continued the relationship in their new lives. Their anatomy turned out to be so similar that Optimus is able to save Elita's life with an energy transfer, and Optimus seemed a bit disturbed when Alpha Trion told them about their origins. When she steps close to him at the end, he even walks away quickly. No one outright mentions the word "incest", but it's heavily implied that something weird's going on.

Also Elita was leaning in for a kiss so it may be more "hero denying his pleasures than anything else." Also three reasons he denied her: parents' anger at robots kissing, kids's reaction to seeing a parental (albiet fictional) figure smooching, and [[RuinedForever Primus forbid G1 Optimus remove his battle mask.]]
