* ''Literature/FromACertainPointOfView'': Ackmena, TK-421 and [[AmbiguouslyGay possibly]] [[spoiler: Tarkin]] are confirmed to be gay/lesbians in this collection of stories. There was no indication of the former two's sexual orientation in ''Legends'', and the latter was originally depicted as being straight (and having a widow) in his ''Legends'' stories.

* ''Film/TheColorPurple'' did not include the lesbian relationships detailed in the book. In the book, Celie explicitly has a crush on Shug and they eventually have a (brief) relationship, however, in the movie, this is mostly reduced to [[HomoeroticSubtext subtext]].

* ''Series/TheBoys2019'':

* ''Series/CowboyBebop2021'' does this with Faye Valentine. In [[Anime/CowboyBebop the original anime]] Faye was clearly into men with her using her feminine whiles to tease and manipulate multiple men, having previously loved conman Whitney Haggis Matsumoto (before he betrayed her) and showing interest in Cowboy Andy (until finding out he's a narcissistic bore), Gren (expressing disappointment when he clarifies he's not interested in women) and Spike (all but stated to have fallen in love with him by the end of the series). Her being fairly captivated by Julia and describing her mysterious beauty to Jet with awe could suggest an [[EvenGirlsWantHer attraction to women as well]], but could also be chalked up to jealousy (her voice actress Creator/MegumiHayashibara has [[WordOfSaintPaul indicated]] she was going for the latter). In the 2021 show however, Faye is unmistakably attracted to women with CanonForeigner Mel being the first (as far as Faye can remember) woman she’s slept with and never showing any overt attraction to men.
* ''{{Series/Cursed|2020}}'': Morgana is portrayed as only having relationships with men in other stories. Here, her only portrayed relationship was with another woman.

* ''Series/DoomPatrol2019'':
** Prior to becoming Negative Man, Larry Trainor was a closeted gay man, and was having an extramarital affair with one of his fellow airmen at the military base where he was stationed. In the [[ComicBook/DoomPatrol comics]] he was straight.

* ''Series/GothamKnights2023'': Stephanie Brown who is straight and Tim Drake's main love interest in the comics, is a lesbian and is Harper Row's love interest.

* ''Series/InterviewWithTheVampire2022'': In the ''Interview with the Vampire'' novel, Louis de Pointe du Lac had feelings for a woman named [[AdaptedOut Babette Freniere]]. His TV counterpart is gay.

* ''Literature/TheMagicians'' has main character Quentin Coldwater as mostly straight but AmbiguouslyBi. ''Series/TheMagicians2016'' TV series makes him bisexual unambiguously.

* ''Series/ThePower2023'': Roxy here likes women, with this not shown in the book (though her sexual orientation wasn't explored). It's later shown she also likes men.
* ''Series/Preacher2016'' depicted [=DeBlanc=] and Fiore as a gay couple, when [[ComicBook/{{Preacher}} the original comic book]] had Jesse Custer interrupt [=DeBlanc=] while he was having sex with a woman near the end.

** Moose in ''ComicBook/ArchieComics'' has never been presented as anything but straight. In ''Riverdale'' he is sleeping with Kevin behind his girlfriend's back and hiding his bisexuality due to being an athlete.

* ''Series/ASeriesOfUnfortunateEvents2017'': "The Penultimate Peril" reveals that Jerome Squalor is bisexual and that Babs from Heimlich Hospital is in love with a woman (implied to be Mrs. Bass from Prufrock Prep). In the books, neither Jerome nor Mrs. Bass showed any evidence of same-sex attraction, and Babs's sexuality was never specified (not that it's important, as the books imply that she was killed by Count Olaf [[WeHardlyKnewYe without the Baudelaires even getting to meet her properly]]).

* In the original ''Literature/TomSwift'' novels, Tom had a girlfriend who he eventually married. In ''Series/TomSwift2022'', Tom is an openly-gay man.

* ''Series/TheUmbrellaAcademy2019'':

* ''Series/TheWheelOfTime2021'':

* In ''WesternAnimation/YoungJustice2010'', the canonical tie-in comic depicts Beast Boy's mother Marie Logan as attracted to women, [[spoiler:[[PsychicAssistedSuicide as she can fall under Queen Bee's thrall]]]]. WordOfGod is vague about whether she's also attracted to men. Interestingly, Beast Boy's father [[AmbiguouslyAbsentParent is never mentioned]], though [[AdaptedOut he and Marie were married in the source material]].

* ''WesternAnimation/Castlevania2017'':

This includes altering their sexuality -- whether making UsefulNotes/{{homosexual}} character straight, giving a sex life to someone described as UsefulNotes/{{asexual|ity}}, putting UsefulNotes/{{aromantic}} characters into romantic relationships, making a straight person gay or bisexual, or any combination or variation of the above. It's debatable whether establishing a gay orientation for a character with a previously unknown sexuality counts -- presumably, "I'll just tell the missus I'll be home late tonight" would slide right by for a minor male character whose marriage wasn't established in the source material, but [[StraightGay would raise eyebrows]] for a woman.

** Korin and Yajirobe are depicted as a same-sex couple (with the former being gay and the latter AmbiguouslyBi), and the ''Broly'' movie opens with their wedding reception.

* While Kim Pines from ''ComicBook/ScottPilgrim'' is merely AmbiguouslyBi in the original books, one of her primary moves in the [[VideoGame/ScottPilgrimVSTheWorldTheGame video game]] is calling Knives out for a quick kiss. [[spoiler:Her ending also has her walk off into the sunset with her, implying a RelationshipUpgrade.]]

* While Kim Pines from ''ComicBook/ScottPilgrim'' is merely AmbiguouslyBi in the original books, one of her primary moves in the [[VideoGame/ScottPilgrimVsTheWorld video game]] is calling Knives out for a quick kiss. [[spoiler:Her ending also has her walk off into the sunset with her, implying a RelationshipUpgrade.]]

** Unlike in the [[ComicBook/ScottPilgrimTakesOff source material]], no mention is made of Ramona and Roxy being "a phase" according to Ramona, so for all intents and purposes Ramona is genuinely bisexual in this version.
** [[spoiler:In this adaptation, Todd becomes really attracted to Wallace, who does not reciprocate his feelings]].

*** Traci herself went from dating [[ComicBook/BlueBeetle Jaime Reyes]] pre-''Flashpoint'' to dating Natasha afterward.

* In the ''Series/WonderWoman1975'' episode "Knockout", Carolyn Hamilton's backstory is that she fell in love with the male leader of the radical group she infiltrated, calling him "a genuinely brave and honorable man". ''Comicbook/WonderWoman77'' (which makes her a CompositeCharacter with Nubia) has her married to Fausta Grables from the episode "Fausta: The Nazi Wonder Woman" (whose sexuality wasn't specified in the series or her [[Comicbook/WonderWoman1942 original comic appearance]]).
** Nubia in ''Comicbook/WonderWoman1942'' didn't have any romantic relationships. In ''Comicbook/WonderWoman1987'', Nu'Bia was motivated by her love for the god Ahura-Mazda. In the ''Comicbook/InfiniteFrontier era book ''Nubia and the Amazons'', she's in a relationship with an Amazon named Io.

* ''Series/WonderWoman1975'': The lesbian Carolyn Hamilton turns out to be an adaptation of Nubia, who had shown no romantic interest in women whatsoever in the [[ComicBook/WonderWoman1942 comics]].

** [[PlayingWithATrope Played with]] regarding the [[ComicBook/UltimateMarvel Ultimate]] version of [[Characters/SpiderWomanTitleCharacter Jessica Drew]] being a lesbian. She's actually an OppositeSexClone of Peter Parker and by her own admission has the [[HasAType exact same preferences as Peter]]: women, especially [[HeroesWantRedheads natural]] redheads like [[ComicBook/SpiderManLovesMaryJane Mark Jane]] and [[GentileJewChaser Jewish girls]] such as [[Characters/MarvelComicsKittyPryde Kitty Pryde]].

** Sir Galehaut, in the legends, is initially introduced as an enemy of Arthur, but who gives this up due to his admiration of Lancelot's knightly virtues, becomes the knight's loyal companion on several adventures, and eventually dies of grief after wrongly being told Lancelot is dead. Unsurprisingly, Paul Gadzikowski is far from the only writer who's written Galehaut as bi (he also has a relationship with Lady Eglante). Lancelot, however [[IncompatableOrientation is straight]], and doesn't pick up on Galehaut's feelings at all.

* In ''Webcomic/ArthurKingOfTimeAndSpace'', Sir Kay (noted for his boorish behavior towards women in the original stories) is in a relationship with Bedivere in the contemporary and space arcs (in the baseline arc, he's still noted for his boorish behavior towards women, [[http://www.arthurkingoftimeandspace.com/2323.htm explaining]] in one [[BreakingTheFourthWall Fourth Wall Breaking]] strip "Yeah, like we're going to be openly gay in the Middle Ages. We probably don't even realize ourselves.") And contemporary and space Tristram is still in the canonical relationship with Isolde... only [[GenderFlip Tristram's female]].

* The Robert Wise version of ''Film/TheHaunting1963'' has an AmbiguouslyGay[=/=]AmbiguouslyBi female character. ''Film/TheHaunting1999'' makes the same character openly bisexual. In the 2018 Creator/{{Netflix}} series ''Series/TheHauntingOfHillHouse'' the same character is introduced as checking out a girl at a bar, her utterly ignoring the guys who check her out, and her and the girl ending up in bed. So full circle one guesses.

* TeamFourStar spinoff series ''WebOriginal/HFIL'' continues the Zarbon jokes, while implying Cell to be AmbiguouslyBi, and having Burtur outright state that he's "gay as springtime."

* In ''VisualNovel/DokiDokiLiteratureClub'', Sayori, Yuri, and Natsuki are in love with the male MC with no indication of them being interested in each other, and Monika is AmbiguouslyBi at most.[[labelnote:Spoilers]]she admits to not minding if the player is a girl, but she shows no interest in the girls in the visual novel proper and generally refers to the player with masculine pronouns, making it unclear if she is actually bisexual.[[/labelnote]] In ''WebComic/DokiDokiLiteratureGirls'', however,[[CastFullOfGay they're all explicitly lesbian/bisexual]] and are in romantic relationships with each other.

* ''{{Series/Cursed}}'': Morgana is portrayed as only having relationships with men in other stories. Here, her only portrayed relationship was with another woman.

* ''Film/GetCarter'': Peter the Dutchman is a misogynistic homosexual in the book.
