History Main / EveryoneIsBi

* Zigzagged by ''Series/ItsAlwaysSunnyInPhiladelphia''. Co-writer Glenn Howerton said he sees every main character this way, except Mac, who is gay [[NoBisexuals despite having clearly been bisexual in previous seasons]].

* All of the main characters in ''VisualNovel/TheArcana'' is romanceable, no matter what your charcter is (you character's gender is never stated but you can choose pronouns and name) WordOfGod confirmed everyone in Vesuvia to be bisexual.

* All of the main characters in ''VisualNovel/TheArcana'' is romanceable, no matter what your charcter is (you character's gender is never stated but you can choose pronouns and name) [[WordOfGod]] confirmed everyone in Vesuvia to be bisexual.

* ''Series/ItsAlwaysSunnyInPhiladelphia'' co-writer Glenn Howerton said he sees every main character this way, except Mac, who is gay.

* ''Literature/ThatIrresistiblePoison'': People on the plnaet of Calluvia can be romantically involved with people of any gender.

* ''VideoGame/{{Fallout 4}}:'' Every companion that you can enter into a romantic relationship with, male or female, is bisexual. This isn't an instance of the game ignoring the Sole Survivor's gender, either -- a companion you're with may refer to you with gendered terms, such as {{MacCready}} saying, "Hey, handsome" if the Sole Survivor is man or "Hey, gorgeous" if the Sole Survivor is a woman.

While it's not TruthInTelevision, it ''is'' truer than people often think. People can be attracted to either gender (or [[{{Asexuality}} neither]]), and if someone's previously expressed an attraction to their opposite gender, bisexuality can be a safe assumption. If you're counting homoflexibility and heteroflexibility, then there certainly are '''lots''' of bi people--but still, not '''everyone''' is bi.

Can sometimes be used for ThreeWaySex, AThreesomeIsHot (or even APartyAlsoKnownAsAnOrgy) and/or {{Polyamory}}. If one were to [[InvertedTrope turn this trope upside-down]], then either there are NoBisexuals, or [[NoHuggingNoKissing everyone is asexual]]. This may be related to BisexualLoveTriangle, but is not necessarily the opposite, as that still requires the different gender characters to contrast against one another. Compare CastFullOfGay. See also JustForFun/{{Kinsey Scale Of Tropes}}.

* WordOfGod confirms that all characters in ''Webcomic/SaintForRent'' are some level of bisexual, unless they're {{asexual}}.

* ''VideoGame/{{Fallout 4}}:'' Every companion that you can enter into a romantic relationship with, male or female, is bisexual. This isn't an instance of the game ignoring the Sole Survivor's gender, either -- a companion you're with may refer to you with gendered terms, such as MacCready saying, "Hey, handsome" if the Sole Survivor is man or "Hey, gorgeous" if the Sole Survivor is a woman.

* ''VideoGame/{{Fallout 4}}:'' Most of the human (or near equivalent) companions can be romanced if you get their RelationshipValues high enough, and the Sole Survivor's gender is irrelevant.

* In ''Literature/TheNeanderthalParallax'', everyone in Neanderthal society is Bi, being expected to take a "man-mate" and a "woman-mate".

* ''Series/{{What We Do In The Shadows}}'': The three main characters, Nadja, Lazslo and Nandor are all bi/pansexual, with the creators confirming the same of all vampires in their universe.

* ''Series/LegendsOfTomorrow '': This is a frequent joke within the fandom, as the main ensemble characters of Sara, John, Charlie, and Gary are all canonically bisexual/pansexual. There is also recurring jokes in the show that suggest that other characters, like Nate, Ray, or Zari, may also be bisexual.
* ''Series/RoswellNewMexico'':

* In the [[TastesLikeDiabetes unbearably cutesy]] ''VideoGame/AnimalCrossing'' clone ''VideoGame/MagiciansQuestMysteriousTimes'', any classmate can be romanced by either gender, which likely earned it its E10+ rating.

* In ''VideoGame/{{Borderlands 2}}'', any character that shows some attraction to the [[PlayerCharacter Vault Hunter]] will do so regardless of the Vault Hunter's gender, several gay relationships are mentioned in passing, and virtually everyone in Sanctuary has some interest in [[MsFanservice Mad Moxxi]]. Although this seems to be because the game didn't have any way of detecting which character you were playing as at all. The following game, ''VideoGame/BorderlandsThePreSequel'', ''could'' detect this, and as a result has more characters that are explicitly attracted to only one gender and even specific characters. Janey Springs for example crushes hard on Athena but says Nisha isn't her type, and isn't into men at all (though she does admire [[BadassBeard Wilhelm's beard]]).

* ''VideoGame/DarkestDungeonII'': the new Amorous relationship can develop between any two heroes, regardless of gender. Whether, for example, the Man-at-Arms hooks up with the Grave Robber, the Highwayman or both (consecutively or concurrently) is entirely down to chance.

* In ''Series/{{Torchwood}}'', everyone in the main cast is at the very least bi-curious. The ''Series/DoctorWho'' episode that introduces Jack Harkness states that [[AnythingThatMoves his omnisexuality]] is common for the century (51st) that he grew up in, in which the [[Franchise/StarTrek Captain Kirk]] [[BoldlyComing approach to first contact]] has been the norm for so long that species and gender lines have become muddled. As Creator/StevenMoffat explains, it's a future where the whole human race is pansexual. Of the Torchwood gang, Tosh and Owen are properly bisexual, Ianto is either just [[IfItsYouItsOkay bi for Jack]] or lying about not being into men who are not Jack, Suzie is seen snogging Gwen, and Gwen doesn't elaborate on which aspect of being kissed by various female villains weirds her out. (WordOfGod has confirmed that Gwen is also bisexual).

* ''Series/TheDailyShow''. ''Everybody'' on the show has either shown bisexual tendencies on screen, or simply mentioned having had sex with both genders.
** More often than not, the bisexuality is played as either comedic misunderstanding themed (Jason Jones once mentions that he married a gay man, after misinterpreting a recent ruling allowing gay marriage) or the correspondent is gay for pay (as seen with Rob Riggle, who had sex with men for money in order to earn the cash to buy an iPhone.)

* WordOfGod for ''Series/BattlestarGalactica2003'' is that all Cylons are Bi. This is actually seen in the Three and Six models.

* In ''Series/{{Farscape}}'', sexuality is completely by-passed as an issue. When you have trans-alien relationships, the actual gender of who you're attracted to becomes moot. It's also implied that humans are comparatively very rigid and backward when it comes to sexuality. Both D'Argo and Chiana seem surprised that humans generally start having sex so late (D'Argo first had sex when he was... seven, Chiana's just confused that they dress provocatively if they're considered underage), and Aeryn illustrates how in the Peacekeepers sex is fine as long as it doesn't involve any emotions. Chiana at least certainly doesn't make any distinction...

** This may be verging into Everyone is Transexual, but in an episode where the crew keep switching bodies, it's shown that both Aeryn and Crichton are intrigued by temporarily possessing each other's anatomies.

** The Literature/{{Hainish}} story "Another Story or a Fisherman of the Inland Sea", introduces the traditional culture of Planet O where pretty much everyone has to be bi for a successful marriage. Marriage is not between two people but four, two men and two women--a man and woman of the Morning moiety and an Evening man and woman. The Morning woman and Evening man, the Evening woman and Morning man, the Morning woman and Evening woman, and the Morning man and Evening man all have sex with each other, meaning every partner in the marriage has a husband and wife from the opposite moiety. (Sex within the moiety is forbidden, so the Morning man/woman and Evening man/woman in the marriage are strictly platonic. In fact, it's perfectly proper for siblings to be the Morning or Evening half of the foursome. Yes, this does mean that you are banging the same woman that your sister is regularly doing, and also the man who would otherwise be your brother-in-law.) The protagonist's mother, a Terran woman of Japanese descent, married in this way to be with the man she loves but finds it strange many years into the marriage, even though she is on good terms with her wife in the marriage. A later story, "Mountain Ways", discusses what happens when this is averted: a gay woman, straight man, and straight woman manage to pull it off by disguising the gay woman as a man and keeping the marriage quiet.
** In ''Literature/TheLeftHandOfDarkness'', the setting is a planet where the dominant species are asexual most of the time, but periodically go into heat, becoming male or female at random in each encounter (but when two people are having sex, apparently one always becomes male, one female).

* Discussed several times in '''WebAnimation/OverlySarcasticProductions''. Red and Blue have both discussed how Ancient Greece had a different view of sexuality from modern western culture. For one, being bisexual was assumed to be the default, while heterosexuality, asexuality and homosexuality were exceptions from the norm. While the number of bisexuals in real life may not have been much different from what it is today, characters in stories were generally assumed to be bisexual until proven otherwise, much like how heterosexuality is assumed until proven otherwise today.

If people are canonically straight, but fanfic portrays them as otherwise, it's EveryoneIsGay (even if they're stating that the characters are bi--it's a NonindicativeName).

* Creator/LarryNiven's ''Literature/KnownSpace'': According to one interpretation, which is in line with the way the Puppeteers themselves generally explain it to non-Puppeteers, Pierson's Puppeteers can be regarded as an entire race of bisexuals. Males are sapient and produce gametes, while females are non-sapient and provide gestation space. There are males who produce sperm and males who produce eggs, while females contribute no gametes but carry and bear the offspring. The female dies after childbirth, and the gay couple raises the kids, no sex except reproduction though. Would be EveryoneIsGay if the couple didn't have sex with a female at one point. An alternate interpretation, one that a human character stumbles upon and considers more accurate, is that the non-sapient "females" are in fact a different species that the Puppeteers are parasitic upon--similar to the Ichneumon wasps that lay their eggs in live insects so that the wasp larvae can eat the host alive. The "sperm-producing-male" is the Puppeteer male, while the "egg-producing male" is the Puppeteer female.

* Just about the entire pantheon in Myth/ClassicalMythology. There’s a few asexuals like Hestia, Athena, Artemis and possibly Hades, and exactly one, maybe, heterosexual god - Ares, but aside from that, basically everyone else is so casual with sex the idea of heterosexuality is down-right quaint.

* Katarina has eight named love interests in ''LightNovel/MyNextLifeAsAVillainessAllRoutesLeadToDoom'', three of whom are girls that originally should have been in love with one of the five boys. This isn't considered unusual by anyone and one of the girls, Mary, is one of Katarina's most aggressive suitors. While not all the boys realize that they're competition, those that do don't find it strange at all. It's also noted that Nicol, one of the boys, has a lot of male fans as well.
