Everyone Is Bi

Go To

"You people and your quaint little categories."
Captain Jack Harkness, Torchwood

On many mainstream TV shows, there are No Bisexuals. Not just in the casts, anywhere — once a person has realized their attraction to the same sex, the opposite sex is expected to be discarded utterly. A bisexual, at best, is either a kinky guest star or the one who did it.

Well, This Is Not That Trope.

This is the other extreme: Everyone Is Bi. Gender — aside from a few token comments — is hardly a factor in the characters' relationships; the gender barrier seems an alien concept.

What this trope is not is, for example, Umlaut House. While about half the cast is bisexual, the other half is explicitly not — and even if the ratio were different, the fact that neither half will shut up about it makes it the antithesis of this trope, in which it's rarely, if ever, mentioned at all.

In video games where you can choose your gender, this trope is increasingly common — not out of any desire to make a particular statement about the characters, but because game developers and writers don't see any reason to cut off any possible Romance Sidequests just because of gender selection, plus it would be more work to put in these limitations anyway. Characters in such games are sometimes described as "player-sexual".

Common in works set in The Future. Often overlaps with Free-Love Future, but not always. Sometimes used in the same way as Outgrown Such Silly Superstitions, to show how "advanced" the future people are, in terms of social norms rather than classical sci-fi technical progress. Expect any straight or gay Fish out of Temporal Water to be mocked for their "closed-minded" and "restricting" lifestyle.

While it's not Truth in Television, it is truer than people often think. People can be attracted multiple genders (or none), 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 Three-Way Sex, A Threesome Is Hot (or even A Party, Also Known as an Orgy) and/or Polyamory. If one were to turn this trope upside-down, then either there are No Bisexuals, or everyone is asexual. This may be related to Bisexual Love Triangle, but is not necessarily the opposite, as that still requires the different gender characters to contrast against one another. Compare Cast Full of Gay.

    Anime and Manga 
  • Revolutionary Girl Utena: The TV series contains suggestive scenes and dialogue between nearly every pair of major characters, including siblings and completely regardless of gender. The director kept pushing the envelope until not even the most die-hard of Have I Mentioned I Am Heterosexual Today? fans could call it "just Ho Yay". Even the manga artist, initially disinterested in the plan for girl-girl intimacy, came around near the end of the series. The brakes came all the way off for the Adolescence of Utena, where the main couple went from the heavy subtext of the series to unambiguous female/female romance.
  • Seems to have been the general assumption in Kyo Kara Maoh!, as it is 'not uncommon' for two men to marry, and the maids who have a betting pool on the main character's relationships don't even take gender into consideration despite his having explicitly stated his heterosexuality several times. Or perhaps they just know better.
  • It seems like absolutely everyone in Hetalia: Axis Powers is at least bi, which is pretty much what happens when 90% of the cast is male but romantic/sexual tension between the characters is still desired. At the very least, Word of God has confirmed that France is bisexual and Sweden is gay for Finland (probably alluding to how Finnish people sometimes stereotype all Swedish men as gay)
    • This extends to the women, too. Hungary, Liechtenstein, Taiwan, Seychelles and even Belarus have shown interest or have been Ship Teased with both male and female characters.
    • Fan Fic often portrays bisexuality as an integral part of being a nation, since technically they don't count as normal humans and they've been around for enough time to not be fazed by same sex relationships any longer.
  • Kaguya Hime: Mostly everyone but not only because of Miller and Akira. Except for Maggey and Mayu, who both definitely think men are dicks.
  • In Mnemosyne, the entire issue of gender in sex is just discarded. For example, the main character Rin has shown to have sex with both males and females, with the one person she's loved for over a millennium being the guardian of the Tree, and the rest of the cast is implied to simply go with what feels good to them. That said, however, gender is an issue to the greater storyline... well, actually it's rather the mix of gender that's important. The point? The only character with real tangible power in the entire anime is a hermaphrodite, Apos, at least until Rin becomes the new Guardian.
  • Gorgeous Carat: Characters' sexualities are never addressed (except for a couple "are you gay?" jokes at Ray's expense). The guys just all want Florian.
  • Vampire Game: Exactly What It Says on the Tin, with the exceptions of Darres, Falan, Vord, and Ishtar, several of which still encourage all sorts of bizzare matchups.
  • While almost any manga by CLAMP may qualify, Cardcaptor Sakura in particular stands out, what with most of its main characters having both opposite-sex and same-sex attractions.
  • Seems to come with the badge if you are a male police officer in FAKE.
  • In From the New World, all of the main characters except Mamoru. When they're 14, their entire class (save him) appear to be in a relationship with someone of the same sex. It's also a case of No Heterosexual Sex Allowed at a young age.
  • While structured heterosexual and homosexual relationships certainly do exist in Sailor Moon, the main characters (Usagi, in particular) are just as likely to blush and be smitten with a beautiful member of the opposite gender as they are someone of the same gender. The series in general also seems to have no stigma in-universe when it comes to straight or gay relationships, as long as the relationship is romantic in nature, it is considered perfectly acceptable (even if said relationships occur between the villains).
  • Seems to be the case with Mobile Suit Gundam Wing, with both male and female characters coming across as potentially having feelings for both same-sex and opposite-sex characters.

    Comic Books 
  • In Strangers in Paradise, most of the female characters have slept with each other, even if they self-identify as straight. However, even if they do not like men, they have also slept with David. Love Dodecahedron does not even begin to describe it, and it is one of the only series to have the characters themselves actually suggest multi-partner pairings in order to deal with the results.
  • Wendy and Richard Pini, creators of ElfQuest, have explicitly stated on several occasions that every single elf in the series is at least potentially bisexual. Although most of the characters seem to express a preference for one sex or the other there are several examples of elves in heterosexual relationships taking time out to have same-sex flings as well, perhaps the most notorious being Leetah and Nightfall's nude dance in Volume 5 of the collected series.
  • Similar to the 51st century in Doctor Who, the eponymous superhero of Midnighter was hit on by a woman in the 96th century who became very confused when he told her he was gay, asking him what the hell being happy has to do with anything. After he explained that he's only attracted to men, she just became even more confused, since she'd never heard of anyone only being attracted to one sex before. In this century, to quote Midnighter himself, "everyone just does everyone". The woman then points to two of her male squadmates who got together after both of their girlfriends dumped them for the other man's girlfriend. Midnighter thought this was hilarious because it meant all of the Heteronormative Crusaders in his own time are just wasting their time fighting a battle they will inevitably lose.
  • In Alan Moore's The League of Extraordinary Gentlemen, the character of Orlando is definitely bisexual, but this makes sense because Orlando is an immortal who changes sex randomly and without warning. However, pretty much all of the female characters (be they historical or mythological) that Orlando spends any amount of time with are bi for Orlando. This includes Mina Murray, the heroine of the series, Fanny Hill, Venus (of course), Marguerite Blakeney and others. And when Orlando is a male, it's at least hinted at and also sometimes explicitly stated that many of his male companions are bi for him also.
    • In Century: 1910, Mina, angry with both Orlando (who's male at this point) and her partner Allan, announces that she'll be in self-Exile To The Couch, and they'll have the bed to themselves. She also comments that she likes Orlando better when they're female.
      • In Century: 1969, Orlando, who's in the middle of a transformation from male to female, offers to let a sexually-frustrated Allan have a go at them. Allan takes them up on this offer.
  • In Artesia, all the Daradjan women seem to be bi, and the men at least have no problem double, triple, or even quadruple-teaming a willing woman. No male characters have yet been shown to be explicitly bi or even homosexual, though.
  • In Jaime Hernandez's "Locas" stories in Love and Rockets, practically every female character is bi, even the lesbian-identifying ones. Except for Vicki, who's a homophobe.
    • One of the Palomar stories features Guadelupe, still reeling from Doralis' coming-out, wandering around and hearing seemingly everyone else confess to having some same-sex attraction.
  • Save Penny, this basically applies to the women in The Adventures Of Olivia as even if they haven't been seen making out with other women, it's more of a sense that they would, but there's only guy(s) around. Basically, if you're hot, you're getting some, too as far as they're concerned.
  • Pretty much everyone in Lost Girls.
  • In some continuites Themiscyra doesn't have sexual orientation as a concept. Most Amazons end up in homosexual relationships because it's a Lady Land, but that doesn't mean that Amazons won't be equally attracted to men if that's an option.
  • Within The Wicked + The Divine's Cast Full of Gay, five out of thirteen of the protagonists are bi, six if you count Ammy.
  • Many works by Gail Simone have explicitly bisexual characters, characters with heavy bi subtext, and in at least one case characters that Simone wanted to make bisexual but was forbidden to do so, which often gives her works this feel.
  • Both Cupids and Cubi from Fine Print are polymorphic in nature and they can shift between sexes at will, so their sexual preference is just as fluid. The same applies to the protagonist Lauren Thomas, who's attracted to both men and women, including having threesomes. All these make up most of the characters.

    Fan Works 
  • Choose two characters in all of fiction. There is a fic pairing those two. Now notice how gender was not specified in the prompt. That is because everyone can be bi in Fan Fiction.
  • The slight majority of the shipping fanfiction about My Little Pony: Friendship Is Magic is generally female on female pairings. Predilections of the fanfic-writing fanbase aside(see above), the fact that the cast is a good 80% female is a big factor. However, the use of humans, Original Characters, crossovers, as well as Rule 63 have created plenty of heterosexual ships. Females becoming paired up with characters such as Soarin, Dr. Whooves, Big Macintosh and Spike have become more popular as well. As a result, the shipping fandom of My Little Pony: Friendship Is Magic can be equated as this.
    • Some stories, in particular, take advantage of this trope; in Twilight's List, Twilight Sparkle expresses interest in both stallions and mares, and when she considers asking her friends out on a practice date, she doesn't even consider the possibility that they may not be interested in mares themselves. Then again, it may have simply been her not thinking about it, because it wasn't supposed to be a real date...
    • Green relies on this as everyone—down to the Princesses—expresses interest in mares, and several characters express interest in (or reminisce on past experiences with) stallions as well.
  • Everyone in the That Damned MPreg universe is bi unless specifically stated otherwise, exclusively straight and gay characters are few and far between.
  • My Immortal: This seems to be the case, though only the guys show it, per the author's opinion that Guy on Guy Is Hot. For the girls, it's just an Informed Attribute. Ebony herself flip-flops between proclaiming her bisexuality and Have I Mentioned I Am Heterosexual Today? for no adequately explored reason.
  • New Tamaran:
    • Amazons, Atlanteans, and Tamaraneans are all proudly bisexual and sex-positive.
    • As are Supergirl, Oracle, Aqualad, Speedy, Bumblebee, Argent and Pantha ... and probably Jinx.
    • On the villain side, Cheshire and Blackfire engage in threesomes with Scarecrow (who consents) and Red X (who doesn't).
  • Absolutely everybody in Kim Possible fanfic, Depending on the Writer.
  • In C'hou across With Strings Attached and The Keys Stand Alone: The Soft World, there are no sexual taboos among the C'hovites and outworlders; hence, Everyone Is Bi. For example, when Ma'ar asks George to sex with her, she tells him to invite the others in and they'll all enjoy one another. (Given that the four are firmly heterosexual, George agrees to sex but asks to leave the others out of it.) Grynun says that inside the castle walls, the four can have sex with each other but with none of the Idris until she has them first. And As'taris ogles the naked Paul and comments to Grunnel that if he'd known what he was missing, he wouldn't have treated Paul so indifferently.
    • This doesn't apply on the Hunter's world; he talks of the “shameful female-men.”
  • In this Teen Wolf fic, Lydia, Jackson, Scott, Allison, Stiles, and Derek are all bisexual and part of a queer advocacy group that Lydia starts because their college's actual LGBTQ group isn't very accepting of bi and trans people.
  • In the Observe The Viewing Globe fan work archive for the Power Rangers fandom, this can be easily handwaved by the fact that Rangers whose powers connect them directly to the Universal Morphing Grid frequently face a Mate or Die scenario due to the Morphing Grid messing with their hormones (i.e. causing "trips" or "spikes" of sexual arousal) as a side effect of holding the Power. The Morphing Grid also causes Rangers, regardless of gender, to feel "sympathy spikes" of hormones in response to the close proximity of horny teammates, so that any Ranger who experiences a hormone spike has at least one teammate, at any given time, to whom he/she may turn for release.
    • As masturbation is not considered a viable release mechanism to those who hold the Power, it's very fortunate that the Morphing Grid appears to grant immunity to pregnancy and venereal disease for Rangers on active duty.
  • Weiss Reacts: Everyone except Cardin and Melanie seems to be bisexual. Ren and Nora have had Ship Tease with other characters of the same gender, Weiss had a crush on Jaune, Pyrrha is implied to crush on Weiss, and so on. Glynda is the greatest example of this; despite ostensibly crushing on Ozpin, she spends half of her own story secretly not crushing on Cinder, Chieri and Yin.
  • Weaponized in The (Edit) War for Ash’s Freedom to not be Betrayed. During the edit war between the Pokémon god Arceus and the mysterious Darkern Edgier, Darkern (as part of his attempts to "improve" the Pokémon world) tries to give Ash a harem; when Arceus prevents him from adding the girls he wants to said harem, he tries to make them bisexual. However, he wrote down "they will all be bisexual" without specifiying who he wanted to be bisexual; as a result, everyone in that universe becomes bisexual. When Arceus points out that he has made both Ash and all his male rivals bi and thus (per Darkern's earlier logic) canonized such pairings, Darkern has a Villainous Breakdown.
  • The oneshot But You Won't Have to Do It Alone takes all the subtext from the Sailor Moon series and rolls with it: every one of the Senshi are queer, though not all realize it yet (especially the very transparently bi Usagi). Most are bisexual/pansexual, but Rei, out of any of the girls, is a lesbian (with her boy-crazy nature from the 1990s anime being overcompensation). The fic revolves around one big Coming-Out Story.
  • Kingdom Hearts Ψ: The Seeker of Darkness plays with this: not everyone is Bi (specifically, Aqua is straight, Lea and Naminé are gay, and Ventus is later revealed to be asexual), but enough of them are that Xion ends up being genuinely confused by the notion that anyone isn't:
    Naminé: (while reassuring Xion that she's not interested in Roxas) I like girls. Only girls. Not boys.
    Xion: (still looking dumbfounded) I don’t understand? Just girls? Why not boys, too?
    Abruptly, several things lined up for Naminé.
    Point the first: Xion had been created as a Replica of Sora, but her appearance and bearing had been greatly informed by Sora’s impressions of Kairi.
    Point the second: Sora was, obviously, either bi or pansexual, given that he was dating both Riku and Kairi.
    Point the third: No matter how in denial she was, Kairi was obviously bisexual.
    Question: Would Sora have picked up on Kairi being bisexual, oblivious as he could sometimes be?
    Consideration: Kairi was incredibly obvious about being bisexual, to the extent where she was the only person who wasn’t aware of it.
    Answer: He might not be actively aware of it, but Sora had incredible subconscious perception and intuition. He’d at least be subconsciously aware of it, if not consciously.
    Point the fourth: Any sexual education Xion had would have come from either Lea, or Sora’s mother.
    Point the fifth: Lea had had no reason to discuss sexuality with either of them, since as Nobodies lacking emotional connections, it wouldn’t have been relevant.
    Point the sixth: Sora’s mother had met Xion only just before she and Roxas started dating, so she would have assumed anything relating to that had already been figured out.
    Point the seventh: Xion’s comments indicated she was likely, without knowing the terms for it, also bisexual.
    Point the eighth: Xion would have had no reason to question her worldview, since the only relationships she was exposed to with regularity was her own, and Sora, Kairi, and Riku’s.
    Conclusion: Xion had no idea it was possible to be attracted to only people of the same gender as oneself, or only people of a different gender than oneself.
  • In the Sin Kids AU, there doesn't seem to be any character, original or canon, that's strictly hetero or strictly gay. While most of the characters have preferences for the opposite sex, they have zero problem with the same sex either.
  • Pokémon Crossing: All three of the leads are bisexual and nobody actively discriminates them for their sexuality. Several supporting characters are bi or implied to be.
  • The Infinite Loops has a justified example, as the coding regarding a looper's sexuality was among the first stuff to be lost during the event that caused the loops and, considering that there are more pressing things to be recovered, the admins don't really attempt to recover it. Thus, a lot of characters who appeared be to straight in baseline will mention taking lovers of both genders.

    Films — Animation 
  • In Sausage Party, there is an orgy scene where all the food characters have sex with each other, regardless of gender.

    Films — Live Action 
  • The Rocky Horror Picture Show. In fact, this is pretty much the entire point of the movie. Pretty much the only two characters who show no bi tendencies are Dr. Scott, who is wheelchair bound, and the Criminologist, who doesn't interact with any of the other characters.
  • Velvet Goldmine has Brian and Mandy and a host of glam rock fans.
  • While it's never shown on screen, the script for Alien was written with the idea in mind that all of the crew members would've banged without regards to gender, except Ash, who couldn't even if he wanted to. Part of the reason for that is none of the characters were written with a specific gender in mind.
  • The extraterrestrials of Paul, at least according to Paul. He also says "It's all about the pleasure."
  • Most mainstream porn, of course, meets this trope halfway—it's true by default for women, but not for men. (There's a fairly small subgenre where it's true across the board.)
  • In Six: The Mark Unleashed, the Community's holographic program instructs new initiates of the Holy Implant that with the New Order brought about by the Leader, things such as monogamy have been done away with so that people are free to move about with partners of either sex. Procreation is only allowed according to the will of the Leader.
  • Crash: Almost all of the lead characters (save for Catherine) are seen having sex with both men and women, including Ballard, Vaughan, Gabrielle and Helen. Catherine is also canonically bisexual, as per the novel, but her affair with a female coworker isn't depicted in the film.
  • What Have You Done to Solange?: Turns out all the victims, along with Solange, enjoyed having regular sex with older boys and each other.
  • She's Gotta Have It: Opal, Nola's lesbian friend, claims everyone is sexually flexible, though they usually settle on a preference (as she has).
  • The Brides of Sodom: Every character who expresses any interest in sex at all has sex with both men and women over the course of the film.

  • In A Brother's Price it is hinted at that premarital relationships to women are nothing unusual. Exactly how common this is remains unclear, but Jerin is not at all surprised when Cira mentions a female lover in her past. There are also female prostitutes for women, although those do pretend to be male, so there might be an overlap with Situational Sexuality.
  • The Mina Davis books Hungover and Handcuffed and Asshole Yakuza Boyfriend are somewhere between this and Cast Full of Gay. More than half of the main cast is bi (though in some cases only by Word of God), but several are of them are gay. A few are straight, though none explicitly so.
  • In Marion Zimmer Bradley's Darkover series bisexuality is very much a social norm on the titular planet. In fact, in many cases, it is actively encouraged, especially among adolescents who are too young to marry and same-sex relationships serve to help prevent teenage pregnancies. Also, as expectation of monogamy is rather lower on Darkover due to it having originally been a Lost Colony with a small initial population, even adults who are married may have ongoing extramarital relationships with people of the same or opposite sex. Because of the age of these works, this was sharply contrasted with the Terran Empire, which reflected more mainstream American social values of the time and thus, despite the setting being in the distant future, had mid-20th Century sexual values. Terrans frequently found Darkovan sexuality more than a little discomforting.
  • That Irresistible Poison by Alessandra Hazard: People on the planet of Calluvia can be romantically involved with people of any gender.
  • In the Kushiel's Legacy series, nearly every d'Angeline character is bisexual. But in other countries this isn't the case—or at least, if their cultures don't allow them to express it. Much of the story is spent in countries other than Terre d'Ange, and sometimes this is a point of Culture Clash.
  • In Diane Duane's The Tale of the Five fantasy series, bisexuality is culturally universal in the world it takes place on. To the extent that they have laws dictating that everyone must have at least enough heterosex to produce a couple of children. After that, they can go back to their real loves.
  • In Piers Anthony's Apprentice Adept series, the serf class on Photon can be inferred to be mostly bisexual—mostly out of having to cater to the whims of the Citizen class (lead character Stile mentions "consensual heterosexual encounters", implying there's been homosexual ones and possibly voluntary). There are however, only two verified bi characters (Tania and Tsetse—naturally both female and hot.)
    • Note that this only became the case in the last book. Prior to that, homosexuality was barely even sidebarred.
  • In the Merry Gentry series, pretty much all of the Fey are supposed to be openly bisexual. Merry herself is all about the heterosex, of course, so that she can reflect the author's own feelings about sex with another woman, which seem to be "ewww gross but that's actually kind of interesting".
  • In Hamilton's other series Anita Blake: Vampire Hunter the number of minor and major male characters who aren't bisexual can probably be counted on one hand (and there are quite a few male characters) including just about every one of Anita's love interests. Interestingly it is made very clear more than once that Anita herself is not interested in women and most of the female characters that are tend to be pretty villainous.
  • In S.M. Stirling's Draka novels, the old 20th-Century genetically-unmodified-human Draka are straight, gay, or bi as the case may be (and with no shame or self-consciousness about their orientation ever); but the genetically-engineered New Race or Homo drakensis Draka, portrayed in Drakon, are all bisexual (and their sexual appetites always ravenous).
  • Anne Rice's The Vampire Chronicles:
    • Lestat is absolutely bisexual; he has an intense love affair with his male best friend before becoming a vampire (nothing subtextual about it; they kiss multiple times, live and sleep together, and are strongly implied to have sex), and harbors deeply erotic thoughts about him even after the transformation. Considering the nature of his inclinations and relationships afterward, it's pretty obvious that he retains a pronounced attraction to men even after his ability or desire for physical sex is lost when he becomes a vampire.
    • In Armand's book, she finally had the main character have sex with persons of different genders before he was turned.
    • The same author's Cry to Heaven runs on this trope. The main (castrated) male character has love affairs with people of both genders, although his same-sex relationships are more numerous and generally more dwelt upon by the author. His two most lasting affairs are with another castrated man and a woman, respectively, and he thinks of both of them as the loves of his life at different points in the novel. He even carries on a sexual relationship with a cardinal in Rome, who (at first) justifies the affair with the church's belief that castration renders the person neither male nor female, and thus a loophole to rules about celibacy. It doesn't last.
  • Larry Niven's Known Space: 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 Cast Full of Gay 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.
  • Basically every book by Billy Martin, a.k.a. Poppy Z. Brite. The exception would be when everyone is gay.
  • An astonishing number of the female characters in the Claudine stories are bi. This is shrugged off with the ignorant contemporary views of sexuality—as Claudine's husband says, "What you little animals do is charming and doesn't mean anything." It's another matter entirely if a man should be interested in both sexes.
  • In the novels by Gregory Maguire (especially The Wicked Years), everyone is bisexual until they state they don't care for one or both genders. (Especially if you're descended from the Thropp line.) Hell, in terms of ruining your childhood, it wouldn't be much of a stretch to pin this on the Baum Oz books.
  • In Fiona Patton's Tales of the Branion Realm, pretty much everyone is bi, and this goes completely unremarked. There is even a Guild of Companions (a cross between bodyguard, courtesan, same-sex sexual partner, and spy) who are contracted to the nobility. The first book revolves around the Crown Prince's relationship with his mother—she wants him to get married and have an heir, he would prefer to shack up with his Companion. He starts a civil war over this. His mother, BTW, has four Companions of her own.
  • In Robert A. Heinlein's Time Enough for Love, Ishtar and Galahad agree to "Seven Hours of Ecstasy," even though they have so far seen each other only in all-concealing biohazard-protection suits and, thus, neither knows the other's sex. It is strongly implied that in their society (the Howard Families colony-world of Secundus), it is considered in bad taste even to care.
    • Each one is pleasantly surprised to learn the sex of the other, as Ishtar is oddly tall and Galahad is oddly short. And both are absurdly beautiful, particularly Galahad (think the statue of David, except not terrified).
    • It's also implied in Stranger in a Strange Land that sexual bonding in the Church of All Worlds can occur between any water brothers regardless of gender, although this is done extremely subtly by Heinlein's standards.
    • In I Will Fear No Evil, Johann (a dying billionaire) has his brain transplanted into a new, young body and becomes Joan. With the body of a woman and the brain of a man, is his attraction towards women or men the gay one?
  • An Informed Ability in the Doctor Who Expanded Universe. In All-Consuming Fire Benny says that bisexuality is the norm in the 25th century (although she personally isn't). Subsequent books set in Benny's home era have offered no evidence of this.
  • The Neanderthal Parallax:
    • Every Neanderthal shown has a male and a female mate. "Nearly all" are said to, but the exceptions aren't seen. Enforced by virtue of living in a segregated society (females all live in the city center, males all live on the rim; the two meet for four days out of every month that they periodically adjust to avoid or encourage fertility, with the latter occurring only once a decade to limit population growth). May also invoke Sitch Sexuality and/or If It's You, It's Okay.
    • It's unclear if the "exceptions" are those who aren't bi, or are those like Ponter, whose woman-mate Klast died of cancer before the events of the series, so he just has a man-mate until he and Mary are bonded at the end of the third book. Daklar Bolbay was Klast's woman-mate, and she split up with her man-mate as well after he was castrated when his brother assaulted somebody so she has no partner as of the time of the novel.
    • We might surmise that some Neanderthals with purely straight or gay orientations also exist and just have a close friend/housemate instead, though it isn't made explicit.
  • Word of God about the Liaden Universe novels is that Liadens should be assumed to all be bi. We see several homosexual encounters but all the permanent arrangements we see on screen are heterosexual—unsurprising for a culture that puts huge weight on providing an heir.
    • However, the Liaden Universe novels don't feature all that many permanent partnerships. Liadens tend to contract a temporary marriage where it is agreed in advance which House will have permanent sole custody of the child to be produced.
  • Swordspoint and The Privilege of the Sword—perhaps not everyone is bi, but the only monosexual major characters are the villainous Lord Ferris (a depraved heterosexual, perhaps?) and Marcus, whose straightness may or may not have been caused by childhood trauma (thereby inverting Rape and Switch).
  • Due to the nature of a dragons mating flights and the fact that over 50% of the dragon population are females that mostly take male riders, it's implied that at least 80-90% of dragonriders in Anne McCaffrey's Dragonriders of Pern series are at least bisexual. Only Gold riders (1%) and Bronze riders (5%) are exclusively heterosexual.
  • In Janet Morris' The High Couch of Silistra and sequels, while being straight seems to be the social norm, homosexual sex is apparently commonplace and completely acceptable. Estri, who begins the novel as a well-woman has a lot of experience servicing men, but when a customer essentially forces her into lesbian sex with another well-woman, she admits to being very aroused by the experience. Chayin and Sereth, two of her primary lovers, also have sex with each other, though only off-screen.
  • In The Culture, considering that the line between species and gender is completely blurred and deconstructed, everyone just seems to go with what they like, no matter what that is. And considering that Culture humanoid citizens can change gender and move into non-humanoid bodies with multiple sexes and... Look, suffice to say that if you brought up sexual orientation to a culture citizen they'd presume you were from a very very backwards planet.
    • This is reflected in their language, which does not differentiate between sexes.
    • In fact, Gurgeh from The Player of Games is considered bizarre because he's straight and has never changed his sex. A friend of his also seen as weird because she spends almost all of her time as female.
  • In The Stone Dance of the Chameleon by Ricardo Pinto, sexuality is pretty much discarded as a point of interest, where straight and gay relationships are equally common-place. The problem comes where you have the Chosen (who are the undisputed "supreme race" so to speak) and the other races (who act as their slaves and who aren't even allowed to look at their faces). Considering that all subservient races are completely oppressed by the Chosen and horrifically bound by The Law, there tends to be a lot of sexual abuse, rape, and subjugation of both genders of those races... and some of the stuff the more sadistically-minded Chosen are into crosses the line of "torture" and becomes Brain Bleach incarnate. In fact, when the main character (who is a Chosen, but brought up away from their culture), finds out that another Chosen has raped his half-slave brother, said Chosen can't understand why he's so upset and is genuinely shocked that he cares so much. Nuff said.
  • Arthur C. Clarke's novel Imperial Earth includes a line in which the protagonist's best friend is described as "aggressively normal," because he seems to have no preference between males or females—most people in the late 23rd Century go both ways but have at least a slight inclination toward one gender or the other.
  • Ursula K. Le Guin's works:
    • The 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. Every partner in the marriage has a husband and wife from the opposite moiety, but has a strictly chaste marriage with their partner of the same moiety. The story "Mountain Ways" features a newlywed man struggling with the fact that he doesn't want intimacy with men— he is, in fact, "straight" as we on Earth would term it. His more worldly husband assures him that people who aren't bisexual do exist, even on O.
    • In The Left Hand of Darkness, the setting is a planet where the dominant species are asexual and agender most of the time, but periodically go into heat, becoming male or female at random once a month. Not only do Gethenians find it strange to prefer loving one sex or other other, they find it strange to prefer being one sex over the other.
  • In Palimpsest it's not as much as Everyone Is Bi but "Everyone is so desperate to go back into Palimpsest that they will slept with anybody with the mark, no matter the gender".
  • Many Mary Renault novels fit this trope. She wrote a lot of historical fiction set in ancient Greece, where bisexuality was considered the norm, for males at least. Some of her Greeks are exclusively or near-exclusively heterosexual or homosexual, but many aren't. The characters in her contemporary novels are also often quite flexible about gender.
  • In the Lyremouth Chronicles series by Jane Fletcher, this is the standard situation for the people on the mainland (the islanders have a more mediaeval approach towards same-sex relationships), to the point where being exclusively attracted to a single sex is almost incomprehensible and rather rare. The closest the mainlanders get to homo/heterosexuality is preferring a single sex, which is put on the same level as a preference for tall people, or people with blond(e) hair.
  • Most of the characters in Bret Easton Ellis' novels are bisexual. They are usually depicted as having sexual encounters of both kinds within the storylines. It may be a bit of Writer on Board.
  • In Outlander Leander by Eisah, Leander and Ellora argue which one will flirt with a Geuranian man to get information. Neither ever considers that the other man would prefer one gender or the other.
  • Dorne in A Song of Ice and Fire has this reputation as its hat, having a more more liberal take on homosexuality — and sexuality in general — than the rest of Westeros. However, while several Dornish nobles are openly bisexual, Martin's standard treatment of sweeping generalizations suggests this reputation is exaggerated.
  • About half the cast of The Picture of Dorian Gray is bi. Then again, it was written by Oscar Wilde.
  • In Daniel Handler's Adverbs, the narrator states that everyone is bi. Many otherwise straight male characters have sex and/or fall in love with other male characters.
  • In Joan Slonczewki's Elysium novels, everyone is bi in the Free-Love Future. In Brain Plague, one male character only dates women, "his obsession medieval." He does get into a relationship with another man but asks him to become a woman.
  • In Samuel R. Delany's Triton, not everyone is bi but most people are. The plurality sexuality for females is male-oriented bisexual and males are most often female-oriented bisexuals.
  • In The Pardoner's Tale Alex is openly bisexual with no clear preference for either gender.
  • Strongly hinted to be the future of human society in the Neil Gaiman short story "Changes". After all, when it's possible to completely change to the opposite biological sex right down to the genetic level by popping a pill and waiting a few hours the whole question of sexual orientation and indeed gender identity becomes somewhat academic.
  • Blink and you miss it, but it's implied in the Malazan prequel The Kharkanas Trilogy. It seems to be the norm that among the Tiste people, marriage happens between opposite sex partners in order to produce children, but outside of marriage no one seems to bat an eye at whoever anyone is sleeping with and several point of view characters are shown to be attracted to people of both genders.
  • In Lions Of Al Rassan by Guy Gavriel Kay, all men seem to be at least Ambiguously Bi. Could be a subversion as it seems to be culturally expected (in universe) of men, especially nobles or royals, to be into Anything That Moves.
  • In The Machineries of Empire, everybody seems to be pansexual, though it's hard to tell, given how little attention anyone is paying to things like sexual orientation.
  • In the Imperial Radch series, the Empire of the Radch has no societal concept of gender, and one Radchaai expresses confusion at how the specific kind of genitalia people have is such Serious Business in some cultures. If anyone in the series is particular about their partner's sexual characteristics, it goes unmentioned.
  • In Tansy Rayner Roberts's Musketeer Space (The Three Musketeers gender-flipped IN SPACE) assume everyone is bisexual unless specified otherwise - Aramis only likes girls and Porthos is the only straight character in the book.
  • Downplayed in Aeon 14: many characters do prefer partners of one sex or the other, but bisexuality is common and unremarkable. This includes viewpoint characters Jessica Keller and Sera Tomlinson in the main series, and Kylie Rhoads in Perilous Alliance (divorced from a male spouse and currently in a relationship with a lesbian woman at least at first).
  • Books of the Raksura: The titular Humanshifting species' genders, gender roles, and social organization are considerably different from humans', and none of them show any indication of caring about gender where potential romantic or sexual partners are concerned.
  • Captive Prince: Most characters in the series are fine with either gender, although their preferences might lean one way or the other and a few are exclusively gay or straight. Sexual orientation is never mentioned explicitly, but Damen makes a note of the fact that Laurent isn't interested in women at all.
  • Because Wizards Live Longer in the Skulduggery Pleasant series, Word of Gay says there is no straight after a few centuries.
  • In the Nightrunner series Skalans and the Aurënfaie don't even blink at same-sex relationships and nobody seems to question it if somebody has lovers of either gender. Protagonists Seregil and Alec are both bisexual and people speculate that they are lovers long before they actually are, even though both have publicly been with women. Also, the Street of Lights, a neighborhood of Unproblematic Prostitution, has houses with different colored lights indicating whether they offer women for men, men for women, women for women or men for men so that patrons can select based on what they are in the mood for. Some houses show more than one color of light.
  • So This Is Ever After: No character is ever explicitly referred by one sexuality or another and seem to all be interested in anyone regardless of gender. Arek sees all members of his party as possible romantic prospects and possibly attracted to him, despite some of them also being blatantly attracted to women.

    Live-Action TV 
  • Torchwood:
    • Everyone in the main cast is at the very least bi-curious. The Doctor Who episode that introduces Jack Harkness states that his omnisexuality is common for the century (51st) that he grew up in, in which the Captain Kirk-style approach to first contact has been the norm for so long that species and gender lines have become muddled. As Steven Moffat 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 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. (Word of God has confirmed that Gwen is also bisexual).
    • A flashback involving two female members of Torchwood 3 in the 19th century (Alice and Emily) shows that they are a lesbian couple. At least one of them may be bi, given that she finds Jack to be pretty, but that may simply require the possession of sight.
    • You can probably just safely assume that everyone in a Russell T. Davies show is bisexual unless explicitly stated otherwise. Davies has explicitly stated that he doesn't really believe in rigid definitions of sexuality, and that all self-identified straight people have at least minor gay tendencies and vice versa. Steven Moffat uses this trope a fair amount, too, though not as much as Davies.
    • Played for Laughs in "The Eaters of Light". The ancient Romans consider 2017 native Bill Potts's lesbianism to be rather old-fashioned. Not That There's Anything Wrong with That, it's just that normal people like both instead of restricting themselves like that, that's all. Bill is suitably confused.
  • The Daily Show. 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.)
  • J. Michael Straczynski's philosophy for Babylon 5 was that in 2258, sexual orientation is a non-issue—not that everyone is bi, people just don't make a point of it. He suggested early on that one of the main characters was bisexual. This turned out to be Ivanova, but it only came up a couple of times.
    • Another interesting note is in the Babylon 5 movie River of Souls we find out that a holographic program was created with an image of Captain Lochley. Garibaldi discovers this program is especially popular with women.
      • It's never established in canon whether Lochley's relationship with her late friend Zoe (temporarily resurrected in "Day of the Dead") was a sexual one, especially since they spent her one night alive just talking. On the other hand, it turns out that Lochley has missed her enough to be using "Zoe's Dead" as her computer password twenty years later. (Word Of Neil is that they were indeed a couple.)
    • In a subtler incidence, Marcus and Franklin pose as a newlywed gay couple when undercover on Mars. Nobody considers this unusual, though people aware that it's a cover do consider it funny—not the idea that they might be gay, but because they make such an ill-suited couple.
  • Word of God for Battlestar Galactica (2003) is that all Cylons are bi. This is actually seen in the Three and Six models.
  • Sex and the City: In the episode "Boy, Girl, Boy, Girl...", Carrie dates a man who later reveals himself to be bisexual. In the last scene, Carrie meets his group of friends at a party and discovers nearly all of them have dated each other at some point, with gender apparently being a non-issue, though there is one effeminate man they refer to as their "token straight" friend.
  • 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...
    • If you count dreams, fantasies, illusions, and mind probes, Crichton had sex with every single member of the crew, including a BDSM fivesome with Rygel. Part of the point of all of these incidents is that even if Crichton never acted on them, he certainly thought about sex with all his crew members.
    • One particularly amusing episode featured an alien who, after being annoying comic relief for 47 minutes, closed out the show by coming on to D'Argo. Up to that point, D'Argo and the viewers had assumed the alien was male (the role was filled by a male actor), but she assures everyone that she is, in fact, female and "Quite the looker." It's not clear whether D'Argo is more turned off by her masculine (by everyone else's standards) appearance or just by her personality. At episode's end, Chrichton checks to make sure that Aeryn is in fact "The female of her species," (although he was probably just joking). It's hard to say where this episode puts the cast in terms of this trope, except to demonstrate just how weird and unpredictable ideas like sexual identity and gender roles become in a cross-species environment. If everyone isn't bi, they might as well be, because all terms and definitions are more or less out the window.
    • Chiana is quite obviously Anything That Moves but there are plenty of comments by/about D'Argo in particular that reveal he just might go both ways as well. The two that come immediately to mind are when Chiana proposes that Crichton have sex to get over his writer's block and when asked with whom, Chiana replies "Me, him, whoever", referring to D'Argo. Also, in the episode when John gets married and asks D'Argo to be his best man, D'Argo replies "I'm with Chiana now, John", the implication being that he'd be perfectly willing to be John's best man if he was single. In the episode Scratch and Sniff John and D'Argo may or may not have slept together; they were so incredibly drunk and drugged up that they blacked out afterwards and couldn't remember if there were girls involved.
    • This may be verging into Everyone is Transgender, 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.
  • Nip/Tuck: Several of the characters have been bisexual and several of the heterosexual men have been raped by other men. Julia becomes a lesbian in season 4 but goes back to her usual two men, Christian and later Sean. Liz, a staunch lesbian, relaxes her standards for Christian. Matt falls in love with Ava, almost gets compelled to do gay porn to pay for his meth habit, and briefly becomes a prison wife in the final season before reuniting with Ava. Merril Bobolit becomes Escobar Gallardo's prison bitch. Gina is seen to have had sex with several men and one woman in one episode. Kimber as a porn star frequently slept with women for work, and frequently had threesomes to make Christian happy. Quentin Costa is a bisexual intersex rapist. Christian briefly had gay dreams about his best friend/business partner Sean.
  • The Mighty Boosh: Ended up like this by season 3 for the most part, if the character wasn't gay. Virtually every minor or major character mistook Vince for a woman and hit on him, and didn't seem put off when he turned out to be a man. Male villains fell for Howard as well, notably the Hitcher, who only wanted to rape women before him. In season one, Howard's female crush showed lots of interest in Vince, but her last appearance saw her falling in love with a female panda, who had previously been on a date with Vince and had an abusive panda ex-boyfriend. Vince himself is Ambiguously Bi.
  • A Touch of Cloth, thanks to Rule of Funny and the Stylistic Suck of the 'writers' ignoring characters' sexualities when it suits them. Ann Oldman is a lesbian but her main love interest is Jack, Jack mostly has female sexual partners but inexplicably hooks up with Tom Boss at the end of Part II, and the Ho Yay is omnidirectional.
  • Zig-zagged by It's Always Sunny in Philadelphia. Co-writer Glenn Howerton said he sees every main character this way, except Mac, who is gay.
  • Black Sails qualifies for this trope. Most of the characters that are shown in romantic/sexual relationships have them with both genders — Eleanor, Max, Anne Bonny and Captain Flint. It's not majorly remarked upon either.
  • Hannibal: It would be far easier to list the major characters who haven't shown some sign of sexual fluidity or outright gone for both sexes. Hero Will Graham and the title character long had a romantic subtext that eventually became text. Alana Bloom had an affair with Hannibal before marrying Margot Verger, who had previously seduced Will for a baby. Jack Crawford would seem to have Single-Target Sexuality for his dying wife, but even he seems to be charmed by Hannibal on some level.
  • In the future world of The Expanse, a significant fraction of humanity appears to identify as pansexual.
  • Westworld: The robotic Hosts in the park don't have sexual orientation in the way humans do, but all are programmed to not be picky in regards to gender so that they can be seduced by any guest. This is most clearly seen in the saloon, where the prostitutes there proposition all guests that enter, regardless of gender.
  • What We Do in the Shadows (2019): The three main characters, Nadja, Lazslo and Nandor are all bi/pansexual, with the creators confirming the same of all vampires in their universe.
  • Brave New World: Bernard comments that "savages" usually have an odd pickiness over gender in their sexual partners, implying in New London no one does (or at least isn't meant to). This is backed up by numerous orgies which show a lot of people switching between opposite- and same-sex pairings then, along with Lenina's friend Frannie casually wanting a "tickle".
  • Feel Good: Discussed by Mae in a standup routine, where as a result she thinks people can be "moved" somewhat from one side to another.
  • Legends of Tomorrow: 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 suggests that other characters, like Nate, Ray, or Zari, may also be bisexual.
  • Roswell, New Mexico: 2 out of the 3 main aliens have come out as bisexual and Isobel outright states that this trope may apply to the aliens.
    Isobel: I mean, what does an alien care about human gender constructs?
  • Search Party: Most of the main cast is revealed to be bi in the final season. Dory and Portia were assumed to be straight until entering into a relationship, and while Elliot identifies as gay, he has sex with Dory. Drew is never confirmed to be bi, but he did kiss Elliot while drunk.
  • I Know What You Did Last Summer (2021): Nearly half of the main characters (Alison, Lennon, Johnny and Margot) are bisexual.


  • Just about the entire pantheon in Classical Mythology. There’s a few asexuals like Hestia, Athena, and Artemis, and then there's Hades and Persephone who only had eyes for one another (very rare case in the Pantheon), but aside from that, basically everyone else is so casual with sex the idea of heterosexuality is down-right quaint.

    Tabletop Games 
  • Maid RPG includes seduction rules that are specifically mentioned as "not in any way governed by gender."
  • Bliss Stage, as the trope namer for Level-Up at Intimacy 5, tends to have a lot of this.
  • In Changeling: The Dreaming, bisexuality is extremely common among the Kithain, and their society is extremely tolerant of the idea. This is mainly because fae souls keep reincarnating throughout history, most changelings have changed genders between incarnations at least once, and true love that defies the tides of time is pretty much a proven fact in their society.
  • Twilight Sparkle's Secret Shipfic Folder is a game about Shipping, so ubiquitous bisexuality helps keep the options open.
  • Dragonblooded Exalted are nobility, and part of the standard sort of breeding program where the goal is plenty of children, but none out of wedlock. Being eminently practical, they encourage Dragonblooded to take same sex lovers during youth, so there is no chance of producing bastards, but eventually settle down in a heterosexual pairing to generate the next generation.
  • In Monsterhearts, the "turn someone on" move can succeed against any character, regardless of gender or stated sexuality.

    Video Games 
  • In the main Pokémon games, "Attract" only works on Pokémon of the opposite gender, but in Pokémon Mystery Dungeon: Rescue Team Red and Blue, where only the player character has a definite gender, Attract works on (virtually) everyone. While "Attract" affects only the opposite gender in the main series, the same cannot be said to "Charm" and "Sweet Kiss", though the earlier might apply to the Pokémon's cuteness.
  • The Sims: For the sake of simplicity, every Sim can romance any other Sim, at least as far as gender goes. There are some obstacles, but none of these are gender.
    • The Expansion Pack The Sims 2: Nightlife complicates things: positive romantic interactions increase a Sim's invisible attraction score to that gender, allowing better chemistry. Gender preference can also decay, so if your Romance Sim flirts with male Sims all the time, they can suddenly stop being attracted to female Sims. Pretty weird, even for a game like The Sims. Whereas if they flirt with both they will be attracted to both.
    • The issue with The Sims was that a Sim would flirt with everyone. They changed it in 2 so that while a Sim would be amenable to sex with either sex, they would only autonomously have one preferred sex, defaulting to heterosexual but homosexual if the user chose to play them that way.
      • In The Sims 2, Sims are asexual by default until a romantic interaction is performed by or on them.
    • In The Sims 3, inactive sims default to heterosexual unless the active sim performs a homosexual interaction with them. This can then result in an entire town of gay people.
    • Much like The Sims 2, upon the game's release everyone started off with no gender preference in The Sims 4, unless they were created as a married couple in Create a Sim, where their preference would then be maxed out for their spouse's gender. A patch introduced sexual orientation in CAS for the first time, allowing players to set Sims as attracted to men, women, both, or neither. However, Sims are still bisexual by default.
  • The asari in Mass Effect are a One-Gender Race of blue women who can breed with anyone (any species, any gender). Needless to say, many asari appear to be bisexual, because they seek people to mate with based on different criteria (with a focus on species, not gender). A few side conversations suggest they don't fully understand the concepts of gender and orientation; for instance, an asari's father is the parent who didn't give birth even if both are asari. While the asari are noted to be extremely attractive by just about everyone, and it's implied that If It's You, It's Okay is in effect for some of their partners, this is averted in regards to other species partnered with asari. A straight human female character in Mass Effect: Andromeda notes that she's not interested in women and turned down advances from her asari colleagues while serving in their military.
  • In the cutesy Animal Crossing clone Magician's Quest: Mysterious Times, any classmate can be romanced by either gender, which likely earned it its E10+ rating.
  • World of Warcraft:
    • One of the succubus's abilities, Seduce, can affect males and females equally.
    • Similarly, each version of the Theramore's Fall scenario has a male enemy that using a stun ability called "Dashing Smile", which affects players of either gender.
    • During the Valentine's day event, PCs can exchange pledges of adoration with NPCs for love tokens. Gender is only a factor in that female NPCs will romance PCs wearing cologne and male NPCs will romance PCs wearing perfume. Either gender can wear either cologne or perfume. Worth mentioning that to get the Largest prize you need at least twenty pledges from each city, Darnassus is all female and Ironforge is all male. On Horde-side, Silvermoon is all male.
  • In City of Villains, Succubi have a power called "Come Hither" that prevents players from being able to attack them directly. Interestingly, it works on both genders just as easily. The spell is broken immediately if the Succubus attacks the player.
  • In Cult of the Lamb, the Lamb has the option to marry any of their disciples regardless of gender (with their own being ambiguous).
  • Fire Emblem Engage has the "player-sexual" variety. The Player Character Alear can S-Support with any character and unlike past games which had specific Gay Options, all romantic S Supports are identical between both male and female Alear.
  • Quite possibly the men of Metal Gear, in which there are three canon bisexual characters — Colonel Volgin, Vamp, and Dolph himself. There's also subtext between Solid Snake and Otacon despite their own things for the ladies, and while Big Boss has no canonical partner he benefits from Everyone Being Gay For Big Boss with EVA/Big Mama and especially when Ocelot goes so far as to sacrifice his own personality/self by using nanomachines and hypnotherapy to make himself think that he was Liquid Snake — hence "Liquid Ocelot" — throughout the events of Metal Gear Solid 4... all for the cause, all for Big Boss.
    • In Metal Gear Online, both male and female characters can learn the Charm ability which causes them to do a sexy dance, stopping other characters in their tracks. The sexy dance does not discriminate based on gender.
      • Neither do the play-boy magazines
    • Big Boss can also go on a date with Miller at the end of Peace Walker and take photos of him on the beach in a thong. That they have sex afterwards may also be relevant.
    • Dr. Strangelove, she has a took a liking for Otacons dad, and she was totally into The Boss, much like Ocelot is to Big Boss.
  • Parodying the Romance Sidequest, all of your homies in Saints Row IV can be "romanced" with a single button press, regardless of your character's gender. And yes, all of them. In the same playthrough. As many times as you want. Even CID, the spherical floating robot. But not Keith David, who just wants to keep things professional. Pierce is notable in that no matter which gender you are, he'll tell you he doesn't normally swing that way. Also, romancing Ben King gives the longest cutscene, in which the Boss seemingly wants to confess his/her feelings for King but Cannot Spit It Out, to which King reassures him/her that he already knows what he/she wants to say and that he wants him/her to say it, as the porno music builds. The Boss just wants him to sign his/her copy of his book.
  • The Elder Scrolls
    • In Morrowind, if you get Personality stat high enough, NPCs of either gender, everywhere that you go, will greet you with the phrase "I like what I see" or something similar. This is, of course, regardless of which gender (or even race) the PC is. Additionally, the response to many of the "Admire" persuasion options appears to be a response to a come-on or pickup line, once again regardless of the player character's gender (or race).
    • In Skyrim, which adds marriage as an option for the first time in the series, every marriageable NPC can be married by the player character, once again regardless of the player character's gender or race. Seems to be a bit of a case of Gameplay and Story Segregation though, as in-universe gay couples not involving player characters are extremely rare, though there still doesn't seem to be any prejudice against them. Of course, this gets Lampshaded by Meta Guy and Fourth-Wall Observer M'aiq the Liar:
    "The people of Skyrim are more open-minded about certain things than people in other places."
  • Downplayed in Vampire: The Masquerade - Bloodlines: most women who can be seduced are available irrespective of the player character's gender, though male NPCs are more likely to be heterosexual.
  • In Cupid, you can match up anyone with anyone.
  • Liberal Crime Squad allows you to seduce people of any gender (and you often don't know their gender before you try to seduce them). The chance of success depends solely on your skills.
  • In Star Ocean: The Second Story, any of the characters in the party can have romantic feelings for any of the other characters, regardless of gender (or age, or marital status.)
  • In Fallen London, there are storylines that allow the player to romance partners of any and every gender...including at least two threesomes. In fact, the text is always written so the PC's gender never makes a difference; "the Dashing Smuggler slips his arm around your waist", for example. (It helps that the PC's gender can be set as "Gentleman", "Lady" or "My dear sir, there are individuals roaming the streets of Fallen London with the faces of squid. Squid! Do you ask them their gender? And yet you waste our time asking me trifling and impertinent questions like that? It is my own business, sir, and I bid you good day.".)
  • Dragon Age II:
    • In Dragon Age II, all the main romance options are available to both genders (appropriately, one of them is voiced by Eve Myles from Torchwood). DLC character Sebastian is the only heterosexual-only romance, as well as being celibate. Several of the non-romanceable companions are also implied to have bisexual tendencies to varying degrees. Aveline can kiss Hawke regardless of gender at the end of her Act 2 loyalty mission, Bethany expresses some curiosity about Isabela's sexual history with other women and Varric has some slightly flirty dialogue with Anders (though his heart belongs to Bianca, his crossbow). Sebastian is implied to have had encounters with men as well as women before he took his Chantry vows, which prohibit sexual relationships. Even Bianca apparently feels some "confusion" when Isabela suggests she needs "a woman's touch on her trigger."
    • The nation of Orlais and the nobility. Because sleeping your way to the top is basically a necessity to play the Grand Game, and since there's no significant stigma against homosexuality in Thedas, it's a well known fact that most Orlesian nobles will bed anyone, male or female, to climb the social ladder, regardless of their actual orientation.
    • The other games in the series avert this trope, with exclusively gay and straight potential romance partners mixed in.
  • In Guild Wars 2, the Sylvari are noted to be like this. They're a race of plants mimicking the humanoid form, are incapable of sexual reproduction, and socially have no concept of gender. Developer blogs about Sylvari society and culture have noted that Sylvari consider gender completely irrelevant, including in matters of love.
  • In Dragon's Dogma, you can end up with anyone. Whether it's a male or female Arisen, you can have male on male and female on female. Some scenes don't even change regardless of gender, and this will cause some characters to come across as this.
  • In Borderlands 2, any character that shows some attraction to the 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 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, Borderlands: The Pre-Sequel!, 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 Wilhelm's beard).
  • In Space Colony, it is possible for any two colonists to become romantically involved.
  • In High School Story, you can pair up any two students and send them on a date. This includes NPCs who may canonically have a straight crush.
  • HuniePop includes a setting for whether the Player Character is male or female. None of the girls you romance react any differently, and Kyu will express her...appreciation of the girls the PC dates. Although it's implied that most of them are just attracted to whatever sex the protagonist is and the only truly bisexual characters are Kyu, Jessie, and probably Venus.
  • In Elona, you can marry and have a child with almost any NPC, regardless of sex or species. In fact, the only effect gender has in the game is determining which form your pets will take when they evolve.
  • World's Dawn asks the player their gender preference at the start of the game, which determines whether bachelors, bachelorettes, or both are going to be interested in you. Given that the Gay Options are one of the things most often mentioned in reviews, it's likely that this is the norm and the mayor simply tells the other townspeople to not hit on you if you say you're only interested in one gender.
  • 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.
  • Stardew Valley features six bachelors and six bachelorettes you can romance and marry, regardless of the gender of your player character. Though it's quite played with, as many of them are shipped with an opposite-sex partner if you don't pursue them romantically, and pursuing a same-sex relationship with one will usually cause them to note that they've never felt this way about another guy/girl before. The one exception is Leah, whose ex Kel will be brought up, and eventually show up, if you reach the romance stage with her. Kel will be the same gender as the player character, retroactively establishing Leah as whichever sexual orientation is needed.
  • Rune Factory 5, as of its international release (and a subsequent patch for the Japanese version), allows players of either selectable gender to romance any eligible bachelor or bachelorette, regardless of the gender of their chosen love interest.
  • Crush Crush: While only Fumi and Pamu specifically mention an interest in women, all of the girls will date you regardless of whether you're playing as a male or female character.
    • The same goes for Crush Crush's spin-off Blush Blush; Eli is the only guy who specifically states that he swings both ways "like a pendulum", but all the guys will enter romantic relationships with you regardless of your in-game gender.
  • In the original Avatar High, any student could date any other. Its sequel Avatar University changed this so that characters have specific sexualities.
  • Digimon Story: Cyber Sleuth has a lot, especially if the main character is Ami. It'd be easier just saying Officer Date isn't one, despite being a Tomboy.
  • In Assassin's Creed: Odyssey, all romance options are available to the player regardless of whether they're playing as Alexios or Kassandra. Given that the game takes place in Ancient Greece, it's probably as Justified as this trope will ever be.
  • In My Time at Portia, all the single characters can be romanced regardless of whether you're playing as a male or female character. This is especially notable in the case of Albert, who otherwise is very vocal in his appreciation of pretty ladies (though this does cast some suspicion on that...), and Antoine, who's unambiguously Camp Gay.
  • Granblue Fantasy has, with a few exceptions (Metera, who is straight, and Sandalphon and Vira, who are very deeply in love with a man and a woman, respectively), everyone be bisexual, or at least not explicitly leaning either way. Some of this is due to the player character of either gender being able to participate on both sides even in gendered holidays (Valentines and White Day are both gendered in Japan, with the latter even existing because of it), but many of them show interest in both sexes. In a rarity for fiction, the characters also have preferences for which gender they prefer, even having their lines changed depending on whether you play as Djeeta or Gran if it applies to them.
  • Every party member in Tyranny is bisexual (except possibly Lantry, who's a bit too old for romance). Kyros is implied to be bi (having a Royal Harem with both sexes) and their empire is very gender-equal in general. Attraction to both sexes seems to be common throughout.
  • Word of God from Dave Oshry, CEO of New Blood Interactive, has confirmed that all characters in games developed by New Blood (including DUSK, AMID EVIL, ULTRAKILL, and Gloomwood) are gay/bi.
  • Divinity: Original Sin II: All of the potential companions can be romanced regardless of the player character's gender and, with a single exception, gender doesn't matter to the other NPCs with whom the PC can flirt. The closest anyone else comes to mentioning sexual orientation is a pimp who enquires after the PC's preferences for the night (and accepts "surprise me" as an answer).
  • Downplayed in Littlewood. The Hero can date any of the Townsfolk, regardless of gender, but the Hero doesn't have a defined gender themselves. Since many of the Townsfolk are implied to be attracted to the player even if they don't pursue their Romance Sidequest, it's more like everyone is Hero-sexual. The only character with obvious sexual preferences outside of the Hero is Bubsy, who seems to enjoy attention from anyone, but mostly directs his own attentions at men.
  • Cyberpunk 2077: Well, not everyone, but in addition to Kerry being bisexual,note  Badass Biker Panam can be romanced by a female V with a masculine frame and vice versa for River. Meredith Stout is available as a one-night stand for any V. Rogue is willing to sleep with Johnny regardless of V's body,note  and Johnny himself alludes to not really caring about the gender of someone willing to sleep with him. V can also be played as bisexual. The only character with an explicitly confirmed orientation that isn't bisexual is Judy, who's a lesbian.
  • Darkest Dungeon 2: The 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.

    Visual Novels 
  • All of the main characters in The Arcana is romanceable, no matter what your character is (you character's gender is never stated but you can choose pronouns and name) and Word of God has confirmed everyone in Vesuvia to be bisexual.
  • The entire cast of Danganronpa V3: Killing Harmony can be romanced by the Player Character in the game's bonus mode.
  • Fate/stay night and its many spinoffs may or may not count, as several characters have been officially confirmed by the creators to be bisexual or explicitly stated so themselves in-universe. It makes sense on the Servants’ part, as most of them are from eras and cultures with very different views on sexuality and same-sex relationships than today. Non-servant characters are also subjected to having both canon opposite- and same-sex attractions or huge amounts of Ho Yay and Les Yay.
  • Little Busters! has both subtext and outright text for both same-sex and different-sex attraction from a lot of characters, the protagonist included (even if the game only has het romance routes). For a bonus, both Riki and Komari either seem to be or outright are attracted to both Natsume siblings.
  • In Magical Diary, not only can the PC date both male and female options, but many NPCs have explicitly dated both, and no one raises an eyebrow. Hanako has also confirmed that this game is running on this assumption.
  • Monster Prom: All four playable characters (two guys and two girls, though you can choose what pronouns any of them prefer) are able to date all 6-8 available romantic interests (three guys and three girls, plus a male-sounding computer and a dark god-turned-schoolgirl in the DLC). Even among the rest of the cast and secondary characters (many of which have secret romance routes), it's made no distinction of gender and pretty much everyone goes for everything. The sole aversions to this are Kale and Coach, who are both asexual.
  • In VA-11 HALL-A, Glitch City is particularly accepting of different sexualities for a Cyberpunk Dystopia, and Jill serves and encounters a lot of people who run the full spectrum of humanoid sexuality, from Alma, who is strictly hetero; to Dorothy, who services both men and women in her work as a Sexbot; to Mario and Betty, who are gay. Jill, herself, is bisexual, having had a slew of relationships with other men throughout high school and a very serious relationship with a lesbian in college. This acceptance isn't uniform, however; Jill's old girlfriend was disowned by her mother because her peers were homophobic.

  • Discussed several times in Overly Sarcastic Productions. 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.

  • By this time, pretty much everyone in Shortpacked! has had both a gay and straight experience with the exceptions of the boss Galasso and Ronald Reagan. Faz even refers to the Kinsey scale, albeit in its original, not modern, meaning ("Now, if I have sex with a woman, I will be a 3!").
  • Most of the cast in Sparkling Generation Valkyrie Yuuki have shown or talked about attraction to both genders. The rest aren't confirmed as either bisexuals or monosexuals as of yet. Of course, most of the cast are Norse mythological figures, where this trope also applies.
  • Bisexuality is the norm for the drow in Drowtales, with purely heterosexual and homosexual people as minorities.
  • El Goonish Shive is a funny case, since characters who have been genderbent by Tedd's TF Gun develop a temporary attraction to the opposite gender. Depending on how you look at it, between one and two characters are naturally bisexual (Ellen is an Opposite-Sex Clone who has all the memories of her original male self, as well as those of a heterosexual alternate self from another universe, and is only just coming to understand that she's a bisexual homoromantic. Grace is "Teddsexual" regardless of Tedd's current gender.), but seven of them have been genderbent, and of those the four straight ones have all had to deal with attraction to both genders. (Justin and Nanase are exempt from this due to being naturally gay—when genderbent, they just get even more attracted to guys and girls, respectively.) And it turns out the straight ones aren't exactly straight—Sarah has recently started considering herself "A Kinsey 2 at most", and Elliott is starting to realise that the way he feels about guys when he turns into a girl has actually not got much to do with turning into a girl. It's unclear whether repeated transformations alter a person's sexuality and/or gender identity, or if it just allows them to realize feelings that were already there but unexplored.
  • While only two characters in Ghastly's Ghastly Comic have ever been called "bisexual", almost every cast member has slept with, kissed, or had a Stupid Sexy Flanders moment with members of both sexes at one point or another.
  • Word of God for The Challenges of Zona is that the Erogenians practice "situational bisexuality" as a matter of course and that Zona and Tula have had lovers of both sexes.
  • Most, if not all webcomics by Gisèle Lagacé tend this way. It's justified in that Sex Comedy is her bread and butter; more possible pairings = more possible jokes. On the other hand, precisely because it is used for purposes of comedy, there tend to be a number of references to this pervasive bisexuality, so it isn't exactly "taken for granted". Also, most of these comics do have a few unambiguously straight or purely gay characters, even if some do discover otherwise as their stories develop.
    • Ménage à 3 starts out with a varied cast of gay and straight guys and girls with one bi girl and, it soon emerges, one bi guy. By the end, pretty much every single named character (and plenty of one-off extras) have had at least two or three instances where they've shown some kind of attraction to both genders, with the exception of Eulice the scary landlady and Rob the shut-in neighbor. The fact is lampshaded on occasion, perhaps in acknowledgement of increasing fan comment on the subject — e.g. by Zii, the aforementioned bi girl, when she calls up Dillon the very Camp Gay (who experimented with heterosexuality just the once, unsuccessfully, but whose experiences are ... complicated), asking to be taught the kissing technique he previously taught Gary, which just so happened to give spectacular results when used for cunnilingus and turned Gary into an in-universe Sex God. She phrases her request... poorly.
      Dillon: You want me to teach you how to go down on a woman?
      Zii: [hanging up] That was a dumb idea. Why can't he be bi like the rest of us?
    • Pretty much the entire cast of Magick Chicks has shown that they wouldn't turn down either sex, however Faith's powerful psychic connection to the school may be causing a Fisher King situation, where all the girls like girls simply because she likes girls and wants all of them to be available to her.
  • Homestuck: Alternian culture is binormative. Trolls reproduce rather like social insects and do not form families, so gender is pretty much cosmetic. Their emotional lives center around 4 types of romantic relationships, 2 of which are usually sexual. While monosexual trolls exist (like lesbian Kanaya), their language lacks words for orientation; Karkat is nonplussed when the human characters try to explain the concept to him.
    John: yes.
    John: shrug. it just is.
  • In Curvy everyone seems capable of making out and having sex with virtually anyone else, on a moment's notice.
  • In UC, only Nicodemus is confirmed, in comic, to have dated both genders, but author created art suggests that the rest of cast is also bi.
  • Due in part to Author Appeal, most comics of Humon's portray a high number of Bi characters. Of note is Niels, where about 80 percent of the protagonists are queer in some way, particularly the title character.
  • Almost everyone in Oglaf, whether due to Rule of Funny or Rule of Sexy. Notable exceptions are Ivan, who keeps getting hit on anyway by a Depraved Homosexual, and Kronar's tribe of butch gay He Man Woman Haters.
  • In The Glass Scientists, The whole main cast is either bi, gay and/or ace. It comes together nicely with a sub-theme of the comic being hidden/repressed sexuality. The author has also stated for the audience to assume all their characters are bisexual unless otherwise said, which gathers every single minor character under that umbrella as well.
  • Zebra Girl: Dream!Sam (a figment of Sandra's imagination) says that everyone is this to some extent. It comes up when Sandra asks why Dream!Crystal is trying to seduce her, and Sam says that Incubus created her by reading Sandra's memories and found Sandra's clandestine feelings for her.
  • In this Manly Guys Doing Manly Things comic, Max freaks out when he realizes he's the only one at the barbecue that isn't bisexual. Later strips expand on this, revealing a good number of characters (but not everyone) have had romantic relationships with both sexes. Commander is afraid after stumbling into a meeting of attractive single fathers that he might settle down again even though he's terrible at it.
    "Anyone else surprised to hear that come out of someone dressed that much like a Rob Halford body-double?"
  • Word of God confirms that all characters in Saint For Rent are some level of bisexual, unless they're asexual.
  • Mr. Boop: Seemingly no one is immune to the siren call of a threesome with Alec and Betty. Subverted somewhat by the fact that Bugs seems utterly uninterested in Alec, and only has a threesome with him in order to have sex with Betty Boop.

    Web Original 
  • Applies to all the male characters of Yu-Gi-Oh! The Abridged Series. The only exceptions are Marik, who is Armoured Closet Gay; Pegasus, who is Armoured Closet Straight; Bakura, who's not gay, he's just British; and Yami Bakura, who's not British, he's just gay.
  • Almost everyone on That Guy with the Glasses will flirt or perv on a person of their own gender if it aids a joke or fanservice. Or in the case of Demo Reel, pure Author Appeal. The reboot of The Nostalgia Critic Lampshaded that all the (in-universe) characters are fluid when it comes to gender and sexuality.
  • Gaia Online's Valentines 2009 event allowed the users to send Valentines to a number of NPCs, who would respond or refuse according to programmed turn-ons or turn-offs. Liam, Devin, and Vanessa refused Valentines based on the sex of the avatar who sent it to them; everyone else had qualifications based on other things and would respond regardless of gender.
    • In addition, there have been three Chance Item sets based on Dating Sims. The user can freely choose whether to pursue a male or female love interest in each, and none of the interests are restricted by the user's gender.
  • The Juno Steel storyline of The Penumbra Podcast falls under this trope; centuries in the future, societal norms have changed to make sexuality a non-issue. None of the six main characters are heterosexual, and quite a few supporting characters are in same-sex relationships, with many of them married. There's one confirmed straight character, and that's Mick Mercury.
  • In the Furry Fandom many characters and members of the fandom seem to have sex with either gender. There have been repeated surveys of the fans and usually bisexuals make up 40-60% of the group. This is at least in part because LBGT people find the acceptance and openness of the community to be an attractive social group, and get into the furry aspects after joining.

    Western Animation 
  • In Archer, Pam is blatantly open about her equal attraction to both genders, Cheryl/Carol cares more about her choking kink than the gender of the person choking her, Archer has admitted to gay fantasies about Joe Frasier (not to mention kissing Ramon), Lana and Malory have both slept with Pam, Camp Gay Ray admits to being attracted to Lana, and Krieger is...Krieger. Cyril may be the only heterosexual member of the main cast.
  • Animals (2016) kind of starts with the so-called dudebro type of humor and guys wanting to get laid with girls. This absolutely goes out of the window in the following two seasons, where every character is attracted to members of the same sex to varying degrees. The finale has Phil and Mike having their The Big Damn Kiss.
  • Drawn Together: Every cast member seems to have slept with or kissed at least one other character of the same sex.
  • South Park: The episode "Two Guys Naked in a Hot Tub" uses a variation on this as an Aesop when Randy and Gerald masturbate in front of each other in a hot tub. This culminates in almost all of the then-current male adult male townspeople admitting to having masturbated in front of another male, declaring that "everyone's a little bit gay".
    • Several episodes use this for Rule of Funny purposes as well, with many male characters being depicted with attractions to both sexes in multiple episodes despite being identified as strictly heterosexual or homosexual, including Cartman, Craig, Mr. Garrison, Jimbo, Stan's Dad, Butters' Dad, Priest Maxi, and Detective Yates.
    • Also applies to several female characters (Liane Cartman has sexual relations with both male and female characters, Mayor McDaniels is implied to have a husband but has had sex with both Officer Barbrady and Liane Cartman.)
  • Superjail!: Maybe? It's not even entirely clear about the gender of the collective main cast. In any case, no one seems to be deterred in their crushes by little things like transsexuality or gender-switched counterparts from another planet/dimension or people who can apparently spontaneously give birth through their anuses. Or death.
  • In Family Guy almost every main character has had bisexual leanings:
    • Peter had sex with Bill Clinton, and claims the happiest day of his life was when Usher invited him onstage to seduce him. He even explicitly came out as bisexual in a Season 16 episode.
    • Lois had a girlfriend in college, has frequent Ho Yay with Bonnie, and agreed with Peter's "Grinds My Gears" rant about how All Women Are Prudes, saying it's why she switched back to men.
    • When Meg went to prison and came back a hardened thug, she bashed her Alpha Bitch bully over the head with a sack full of soda cans and then made out with her unconscious body. Another episode revolved around her faking lesbianism in order to have friends, but she ultimately couldn't go through with actually having sex with another girl and had to come out as straight. Although said girl then pretty much outright stated that all women in the Family Guy universe are bi and only men can be gay or straight.
    • Stewie's sexual orientation seems to be whatever the current joke calls for.
  • Word of Gay from one of the storyboard artists for Star vs. the Forces of Evil, Sabrina Cotugno, claimed this in response to another storyboard artist, Kristen Gish, trying to pull God Does Not Own This World on the characters' sexual orientations. Incidentally, Cotugno also happens to be the creator of The Glass Scientists mentioned above.
    Cotugno: Marco is bi! Star is bi Everyone is bi! It's the law now! Everyone enjoy your brand new bisexuality™!
  • Several main characters in She-Ra and the Princesses of Power are explicitly or implicitly bisexual.
  • Pretty much every character in All Hail King Julien is implied to be bisexual, but because it is a children's show, it is never said out loud. Most obvious examples include Mort who has been married to 12 women but is explicitly attracted to Julien, and Julien himself who usually hits on women, but doesn't mind it when men are interested in him and even is willing to mate with a fossa despite not knowing it's gender.
  • Rick and Morty: The sixth season of this show revealed that the Smith-Sanchez family is either bi or pansexual with the only member who is seemingly heterosexual being Morty

Alternative Title(s): Everyone Is Bisexual
