History GenderBender / FanWorks

!!''Franchise/{{Danganronpa}}''
* ''[[https://www.fanfiction.net/s/13317247/1/Danganronpa-Improper-Avatar Danganronpa: Improper Avatar]]'' has Hajime arrive in Hope's Peak like at the start of ''VisualNovel/Danganronpa2GoodbyeDespair'', only to find out that he's now a girl. The same process also happened to Nagito, Chiaki, Fuyuhiko, Peko, Mahiru, Mikan, and Kazuichi. [[spoiler:The discussion between Makoto, Kyoko, and Byakuya implies that this was the result of sabotage by Izuru Kamakura]].

* ''Fanfic/VoyagesOfTheWildSeaHorse'': In addition to the canonical example of Ranma, Ryoga eventually has his [[BalefulPolymorph Spring of Drowned Pig]] curse swapped out for a copy of Ranma's Spring of Drowned Girl curse. He notes that this would ''not'' be his preference, but turning into a girl is a legitimate step up from turning into a pig at the best of times, and considering they are sailing the [[DeathWorld Grand Line]], where the list of animals and ''people'' big enough to [[SwallowedWhole devour P-chan in one bite]] is too long to count, it's really his only practical option apart from just giving up and living quietly on an East Blue island somewhere.

!!''WesternAnimation/MiracolousLadybug''

!!''Manga/CodeGeass''

* ''[[https://www.fanfiction.net/s/3872674/1/Account-Transfer Account Transfer]]'': [[Manga/RanmaOneHalf Ryouga]] has his original curse overwritten with one that causes him to turn into a girl as part of his wish to have Ranma's problems.
* ''Fanfic/AllBecauseOfUncleGary'': Uncle Gary's ritual permanently swaps the sex of whoever it's performed on if fewer than three people chant the incantation. This happens multiple times across the comic: Greta is first, followed by [[IdenticalStranger Julie Webber]], and finally [[spoiler:Abigail's entourage]].
* ''[[http://www.fanfiction.net/s/8092152/1/Blessing-In-Disguise Blessing in Disguise]]'', a ''ComicBook/SpiderMan'' fanfic: The radioactive spider who bites Peter Parker is female, which results in Peter not only gaining spider powers, but turning into a girl.
* ''FanFic/BoyScoutsOneHalf'': One of the main characters, Matthew Atanian, fell into the same cursed spring as Ranma and thus has the same curse. A later introduced character, Perfume, is a woman who fell into Spring of Drowned Boy, and thus has the inverse curse.
* ''Fanfic/ChildOfTheStorm'':

* ''[[https://www.fanfiction.net/s/13740751/1/Distorted-Reflection Distorted Reflection]]'': A battle with a D'arcmon damaged both Taichi's and Mimi's digivices. When they wake up the next morning, they find themselves in the opposite gender thanks to the damaged Digivices swapping data. The more they use their Digivices, the more they get repaired and in turn make it harder to return to their original genders. While their partners Agumon and Palmon remain the same, it's their ''Digivolutions'' that are affected. Agumon now digivoles into the female Sunflowmon, while Palmon digivoles into the male Growlmon.
* ''Fanfic/{{Domoverse}}'': Ron, who turns into a girl over the course of several hours after getting hit by a car and his mutant power manifesting.
** Estelle becomes a boy over the course of a year thanks to her mutation.
** And Ruth, who used to be [[spoiler:Isaac]]. This was done very much against her will.
* A rather odd example in the ''Literature/FateZero'' parody fic ''[[https://m.fanfiction.net/s/11896019/10/ Fate Crazy Knights]]'' which has Arturia able to summon her Knights of the Round (minus Lancelot, who is summoned as Kariya's servant) and Merlin. Initially, the knights Gareth and Galahad start out male. However, following the release of the Camelot chapter in ''VideoGame/FateGrandOrder'', all the Knights that debuted or were talked about in that singularity undergo character updates in chapter 10, leading Gareth to become a girl and Galahad to fuse with Mash (who is fused with his power in the game). While Merlin is able to turn Galahad back to normal, he can't do the same to Gareth because she doesn't mind being a girl, especially since she can become Gawain's favorite little sister instead of competing with Gaheris for the role of favorite little brother.
* In an interlude from ''Fanfic/FateSunnyOrder'', it's revealed that years ago, Ritsuka and Kana Tohsaka found Kaleido Ruby, who activated with blood from a cut on Ritsuka's hand and turned him into a magical girl. While Shirou was able to free his son from being a magical girl with Rule Breaker, it left Ritsuka still as a girl. The family had to wait for two weeks for Zelretch to turn their son back to normal, due to Ritsuka's girl body being made from aspects of multiple female counterparts.
* ''Fanfic/FatesCollide'': Arthur Pendragon became Arturia after too many class changes in Chaldea Academy. She later had her daughter Mordred [[spoiler:following an affair with Diarmuid Ua Duibhne]].
* ''Literature/TheLordOfTheRings'' fanfic ''[[https://www.fanfiction.net/s/4300110/1/A-Day-in-Time A Day in Time]]'' revolves around Merry waking up in the bodies of his ancestors, one of whom happens to be his very pregnant (and about to give birth) great-grandmother.
* ''Fanfic/DoingItRightThisTime'': When Kaworu decided to send himself and the other Children back in time to prevent the end of the world, he thought he might avert to play his role in the Dead Sea Scrolls prophecies if he changed sexes. So he turned female.
* In ''Fanfic/EmpathTheLuckiestSmurf'', both Tapper and Duncan [=McSmurf=] get transformed into Smurfettes by a wish made with a magic egg, and Hefty gets partially transformed into one by Ghinelle the girl genie, who gets even on behalf of her mistress Smurfette for Hefty trying to use SexualExtortion to keep his mouth shut about Smurfette having a genie.
* ExactlyWhatItSaysOnTheTin in ''[[https://www.fanfiction.net/s/11946465/1/Genderbent Genderbent]]'', where a dust mixture Jaune made is spilt onto him, Pyrrha, Ren, Nora, and Yang, turning them into the opposite gender. Later, an antidote made to turn Yang into a girl again is used on Weiss and Blake by Nora, turning both of them into boys.
* In ''Fanfic/GGKronosButIHaveForesight'', the main character, Evan Gamble, is turned into a girl named Eve upon being pulled into the ''Literature/PercyJacksonAndTheOlympians'' world. This is due to Artemis and Hera refusing to accept the help of a guy when a girl could do it just as well, and Aphrodite suggesting this compromise.
* ''Literature/HarryPotter'' works:
** Played with in ''[[http://www.fanfiction.net/s/5353683/1/The_Girl_Who_Loved The Girl Who Loved]]'', via a crossover with ''Manga/RanmaOneHalf''.
** ''Fanfic/InThisWorldAndTheNext'' has Ron turn into a girl as a consequence of a GroinAttack by a troll. It MakesJustAsMuchSenseInContext.
** [[http://www.fanfiction.net/s/8175132/1/Jamie_Evans_and_Fates_Fool Jamie Evans and Fate's Bitch]] is one of many super!Harry PeggySue fics, except when Harry comes back, he ends up in the wrong body.
** In ''Fanfic/BecomingFemale'', Snape makes Harry drink a potion which turns him into the perfect female form.
** ''[[https://www.fanfiction.net/s/10073299/1/Harry-Potter-And-The-Unexpected-Second-Life Harry Potter and the Unexpected Second Life]]'' is an alternate ending to ''[[Literature/HarryPotterAndTheDeathlyHallows Deathly Hallows]]'' where both Harry and Ron after the Battle of Hogwarts are victims of the Widowmaker poison, which only affects men, and only survive by taking Polyjuice Potion and turning into Hermione, and end up having to stay female for several months while they still have the potion in their systems.
** In ''[[https://www.fanfiction.net/s/232736/1/Ah-My-Witches-Though-Some-Previously-Could Ah! My Witches (Though Some Previously Could Not Be Considered Witches)]]'', Voldemort's newly invented immortally potion ends up turning himself, Draco and Lucius into [[Manga/AhMyGoddess Skuld, Urd and Mara]] respectively (Narcissa also takes the potion, but since she was already female, she just turns into Belldandy).
** In ''Fanfic/WaterAerobicsForTheAquaphobic'', during a poorly-planned Hogwarts field trip to [[Manga/RanmaOneHalf Jusenkyo]] that resulted in most of the students being cursed into various forms, Ron falls into Spring of the Drowned Violent Tomboy, which curses him to turn into Akane Tendo whenever he gets splashed with cold water. Theodore Nott is similarly transformed into a siren, a kind of female monster like a humanoid equivalent of a black widow, and there was also a grandfather of Sirius' who apparently fell into the Spring of the Drowned Double-Jointed Concubine.
** In ''[[https://www.fanfiction.net/s/2477343/1/Potion-99 Potion 99]]'' Harry takes a potion to permanently turn himself into a girl because the wizarding world is extremely bigoted about homosexuals and crossdressers.
** In ''[[https://www.fanfiction.net/s/3654234/1/Changes Changes]]'' Harry turns into a girl because Metamorphs experience a random major physical change when their powers first awaken. Due to the inadvisability of shifting anything more complicated than soft tissue, the change is permanent.
* ''Fanfic/TheInfiniteLoops'' will occasionally reboot a looper as the opposite gender. Twilight speculates it happens roughly two percent of the time. Some loopers do this more than others, such as [[VideoGame/MassEffect Commander Shepard]] and [[VideoGame/FiveNightsAtFreddys Bonnie the Bunny]].
* In ''Fanfic/InheritanceOfCardsAndDemons'', this is the power of the Switch card, as [[Manga/BlueExorcist Rin]] finds out when it turns him into a girl named Sora.
* In ''[[https://archiveofourown.org/works/23276197/chapters/56705365#workskin Interviewer]]'', a photographer named Cecilia gets akumatized with this power thanks to the frustration of Lila refusing to follow directions and the latter misgendering [[UsefulNotes/{{Transgender}} the former]]. The transformation are merely biological, so while Ladybug and Chat Noir are outright transformed, the already trans-girl Juleka becomes a cis-gender girl and Plagg (who is essentially genderless) is unchanged.

* ''[[http://web.archive.org/web/20011225065823/http://www.fortunecity.com/lavendar/pimlico/131/hhalf.htm Joel 1/2]]'': An invention turns [[Series/MysteryScienceTheater3000 Joel]] into a woman. It should be noted that it was the author's idea for how the show could keep Joel himself on with Joel Hodgson (His actor) leaving (It was written before Mike officially became host).
* In the ''Literature/HaruhiSuzumiya'' fanfic ''[[https://www.fanfiction.net/s/5453599/3/Kyonko-s-New-Life Kyonko's New Life]]'', Haruhi causes two universes where the cast are [[GenderFlip opposite genders]] to merge, resulting in those in the know of TheMasquerade switching minds with their [[GenderFlip alternate selves]]. Our poor OrdinaryHighSchoolStudent and CosmicPlaything Kyon is now a girl with ACupAngst who still has to deal with the ever insane and domineering alternate universe Haruki.
* In ''Fanfic/KaijuRevolution'', it's speculated in Yongary's entry that all of the species start off as female, with the largest individual becoming the male.

* In ''[[https://archiveofourown.org/works/27518512/chapters/67295026 Let's Go! Akane-kun]]'', [[Manga/RanmaOneHalf Akane]] wakes up one morning to find that not only has she become a boy, everyone she knows thinks that she has always been male. In addition, she (or rather "he") is now engaged to Shampoo, and Ranma is engaged to Nabiki.
* In ''Fanfic/TheMerryGoRoundBrokeDown'', it's implied that Simon went through an incomplete, or even full, transformation. He still at minimum identifies as male, but it's also mentioned that he has the "wrong parts" as a weird side-effect of being turned into a CG character. He's also [[MisterSeahorse for some reason pregnant]].
* The ''WesternAnimation/KimPossible'' fic "[[https://www.fanfiction.net/s/3384624/1/Match-Ado-About-Nothing Match Ado About Nothing]]" features another villain's warped obsession with the idea of Kim and Shego being together driving her to turn Kim and Shego gay. Since Kim still loves Ron but can't be with him physically, Ron ultimately accepts it when Shego and [=DNAmy=] turn him into a woman with a Genetic Resequencer so that he and Kim can continue as a couple.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' works:
** ''Fanfic/BecomingPonies'' has, as its core concept, fans of the show waking up with the bodies of the show's characters. Given the infamous PeripheryDemographic, this was inevitable.
** [[ManipulativeBastard Tzeentch]] does this to [[TabletopGame/Warhammer40000 the God-Emperor]], mixed with {{Animorphism}}, at the end of their fight in ''Fanfic/TheGodEmpressOfPonykind''. The Emperor/Princess Celestia is pissed off at first, but gets used to it after a few years.
** A few non-canon stories in ''Fanfic/TheNonBronyverse'' involve this. One where TD gets turned into a pegasus mare by poison joke, and another where he becomes an alicorn princess. Both times he's rather horrified.
** ''Fanfic/FiveScoreDividedByFour'' features this as part of its main premise, with more than a few of the main cast being men-turned-mare and woman-turned-stallion in equal regards.
** ''Fanfic/JusticeLeagueOfEquestria''; in one side story to ''Mare of Steel'', Rainbow Dash gets turned into a colt due to exposure to Red Kryptonite. She really doesn't want to stay a colt, especially when [[ItsAllAboutMe Maxima]] tries to take her[=/=]him as a mate.
** ''[[Fanfic/LivingTheDreamKickass222urmom Living The Dream]]'' has Lance and his friends turned into mares (Excluding Vinetion) by Annabel the Draconequus. The reason why she did this is because she [[MassHypnosis hypnotized]] the entire male population of Manehattan into sex hungery beasts. The goal is for the bronies to survive an entire month without getting raped. And on top of that, All the Mares of Manehattan were turned into additional stallions to make it harder for Lance and Friends.
** In ''Fanfic/PoniesAfterPeople'', it's possible for someone to change sex when they become a pony.
** ''Fanfic/WhenAPonyCalls'' revolves around a brony accidentally switching bodies with Lyra, a female unicorn. Later, [[spoiler:his original body winds up being gender bent by Twilight, as a result of Lyra not being able to handle male hormones. Also, it turns out being stuck in a magical environment is slowly turning his now female body into a pony too.]]
** The ''WesternAnimation/TeenTitans'' crossover ''Fanfic/MyLittleTitan'' has the Titans wind up in the bodies of the Mane 6. Naturally, this means the male Titans have this happen to them with the exception of Beast Boy, who ends up in Spike's body. Cyborg is not happy about this last part.
** Navarone finds a pair of artifacts that change the gender of the user in ''FanFic/DiariesOfAMadman''. Occasionally they get used for disguise ([[PowerPerversionPotential as well as other things]]) -- at least until they break...
** ''Fanfic/ADiplomaticVisit'': While all changelings can change gender at will, chapter 25 explains that it is expected, when male changelings mature to become their hive's Queen, for their baseline biology to permanently change into a female's in the process. [[spoiler:Thorax remaining male partway through his transformation surprises them.]]
** The M-rated ''Suspenders-verse'' by Creator/{{Evilhumour}} mentions that Cadance can take a male form, Bolero, when she wants to; most prominently, she did so in order for she and her wife Gleaming Shield (this universe's Shining Armor) to conceive their daughter Flurry Heart.
** In ''Fanfic/PoniesAfterPeople'', it is possible for someone to change gender when they become a pony. [[spoiler:This happened to the protagonist, Alex, who was once a man but is now a mare.]]
* In ''[[https://www.fanfiction.net/s/11292442/1/ Nil Desperandum]]'', Lelouch's mind is sent back to the day of Britannian invasion of Japan [[spoiler:after his death in the Zero Requim]]. However, the body he ends up in is a female version of himself named Luluka.
* ''Fanfic/PokemonMysteryDungeonJournal'' did this for April Fool's Day 2013. None of the cast seemed to notice.

* ''[[https://www.fanfiction.net/s/11431303/1/Red-White-and-Blue Red, White, and Blue]]'', a ''Series/BuffyTheVampireSlayer'' crossover with the Franchise/MarvelUniverse, in which a Halloween costume sticks Xander with Mystique's powers and base form, and an inability to resume his own appearance... so he morphs into Willow, and poses as her cousin.
* Applies in a sense in the ''Series/StargateSG1''/''Anime/YuGiOh'' crossover "Fanfic/TheSerpentsVow"; Seto Kaiba is the Goa'uld Queen Set, also known as Nephthys, but despite being a Queen and hence capable of giving birth to other symbiotes, he has retained the same male host since ancient Egypt and considers it just as much his true form as the symbiote.
* ''WesternAnimation/TheSimpsons'' fanfic ''[[https://www.fanfiction.net/s/2306129/1/Lisa-%3C!--C2--%3EBD Lisa 1/2]]'' has this happen to both Bart and Lisa, after they fall into [[Manga/RanmaOneHalf the spring of drowned girl at Jusenkyou]]. Bart turns into a five-year-old Chinese girl named Ping, while Lisa, who went in after him, turns into Bart.
* In ''[[https://www.fanfiction.net/s/13982750/1/Switching-it-Up Switching it Up!]]'', thanks to Mousse switching everyone's curses (except his own) around, Ryouga gets Ranma's curse and is cursed to turn into a blonde-haired girl every time he gets splashed with cold water.
* In ''[[https://www.fanfiction.net/s/3522356/1/Take-the-Green-and-Go Take the Green and Go]]'' [[Manga/RanmaOneHalf Ranma]] is cursed with a female form, as in canon. Unlike canon, however, said female form is [[WesternAnimation/KimPossible Shego]], who had been sent back in time and drowned at Jusenkyo. Will Du later falls into Spring of Drowned Girl (the spring Ranma fell into is Spring of Drowned Demon Woman) and is cursed with the form of a blonde-haired girl.
* While uncommon, Film/{{Thor}} fanfics where Loki turns into a woman are not too hard to find. It's usually explained [[spoiler: by the fact that he's a frost giant]] and inspired by Norse myths of the gender-changing god (see the "Norse" entry in the "Mythology" tab). [[http://savu0211.deviantart.com/gallery/43010983?offset=24 (All) Father Loki]] is one such fic by Creator/{{Savu0211}}.
* A downplayed example features in the ''Fanfic/TokraApocalypse'' series when the Winchesters and Bobby Singer have to stop a demon-possessed scientist travelling to ''Destiny'' via the communication stones (nobody knows if a demon ''could'' travel along the stones, but obviously nobody wants to find out). During the confrontation, Bobby triggers the stone and arrives on ''Destiny'' in the body of Chloe Armstrong. However, aside from TJ musing that Chloe is "probably freaking out right now" and Bobby warning the boys not to talk about it once he gets back to his body, Bobby's visit to ''Destiny'' is focused instead on warning the crew how to protect themselves from potential demonic incursion, with no sign that he's really paying attention to his new body.
* ''[[https://lycelia.com/s/iu Trapped]]'', a virtual genderswap fic in the ''Anime/SwordArtOnline'' fandom, in which Kirito is stuck playing as his little sister's avatar in the death game for years.
* ''Literature/WhateleyUniverse'':
** ''Fanfic/{{Kitsune}}'': Conner Jeremy Fox, a 39+ year old man, [[FountainOfYouth age-regressed]] into a teenager girl.
** ''Fanfic/{{Maat}}'': 70+ year old Doctor Daniel Edward O'Neill transforms into Dani, a [[FountainOfYouth 20-something]] female priestess of Ma'at.
* ''Fanfic/VoyagesOfTheWildSeaHorse'': In addition to the canonical example of Ranma, Ryoga eventually has his [[BalefulPolymorph Spring of Drowned Pig]] curse swapped out for a copy of Ranma's Spring of Drowned Girl curse. He notes that this would ''not'' be his preference, but turning into a girl is a legitimate step up from turning into a pig at the best of times, and considering they are sailing the [[DeathWorld Grand Line]], where the list of animals and ''people'' big enough to [[SwallowedWhole devour P-chan in one bite]] is too long to count, it's really his only practical option apart from just giving up and living quietly on an East Blue island somewhere.
* The ''Franchise/MyHeroAcademia'' fanfic ''[[Fanfic/{{Hammerverse}} When all you have is a Hammer]]'' has this as Izuku's quirk. It's unusual in that Izuku gets the ability when they’re just four years old, and they identify as non-binary regardless of which form they’re in.
* In ''WesternAnimation/TheFairlyOddParents'' fanfic ''[[https://www.fanfiction.net/s/3661478/1/The-Wrath-of-Remy-Buxaplenty The Wrath of Remy Buxaplenty]]'', a malicious wish from Remy turns Timmy into his Timantha form. The FirstLawOfGenderBending also applies, as Remy wishes that Timmy would remain female permanently.
* When ''Anime/YuriOnIce'' was announced, a lot of Western fans thought it meant [[YuriGenre that kind of yuri]], and were surprised to see that it's actually about ''male'' figure skating. In Japanese, all [[OneSteveLimit three]] versions of "Yuri" are written differently... making [[YuriGenre Yuri]] [[Anime/YuriOnIce On Ice]] a convenient pun for doujinshi in which the male characters are genderbent, at least one of which does exist.
* Discussed in ''[[Fanfic/TheZeroContextSeries Zero Context: Taking Out the Trash]]''. The central protagonist had been born a male named 'Curtis', and had at some point been mutated into a cat-like humanoid with special powers. Curtis liked [[IJustWantToBeNormal being human]] more than he liked having his superpowers, and years later took advantage of a magical wish-granting crystal he'd found to regain his humanity and reset himself back to square one--even if it meant completely forsaking his masculinity to become a girl, turning into 'Callista'. A nurse in the epilogue had to make it clear to her patient that this didn't automatically mean Callista considered herself transgender, stating that she'd been called such by some who had heard the term before but didn't fully understand what it meant.

* ''[[http://www.fanfiction.net/s/8092152/1/Blessing-In-Disguise Blessing in Disguise]]'', a ''Franchise/SpiderMan'' fanfic: The radioactive spider who bites Peter Parker is female, which results in Peter not only gaining spider powers, but turning into a girl.

* ''[[https://www.fanfiction.net/s/11431303/1/Red-White-and-Blue Red, White, and Blue]]'', a ''Series/BuffyTheVampireSlayer'' crossover with the MarvelUniverse, in which a Halloween costume sticks Xander with Mystique's powers and base form, and an inability to resume his own appearance... so he morphs into Willow, and poses as her cousin.

* In ''Fanfic/PoniesAfterPeople'', it is possible for someone to change gender when they become a pony. [[spoiler:This happened to the protagonist, Alex, who was once a man but is now a mare.]]

* ''[[https://archiveofourown.org/works/49292365 Prompt: The Transformed Lament]]'': This ''[[Fanfic/TheLamentSeriesChaoticNeutral Lament Series]]'' RecursiveFanfiction has Lila Rossi wishing she had Adrien's life, [[BeCarefulWhatYouWishFor the result of which causes her to become Gabriel Agreste's]] ''[[BeCarefulWhatYouWishFor son]]'' [[BeCarefulWhatYouWishFor rather than her daughter as she wanted] ]. She's also stuck with aspects from her male self, such as his all-consuming crush on her ArchEnemy Marinette.

* ''[[https://archiveofourown.org/works/49292365 Prompt: The Transformed Lament]]'' has Lila Rossi wishing she had Adrien's life, the result of which causes her to become Gabriel Agreste's ''son'' rather than her daughter as she wanted. She's also stuck with aspects from her male self, such as his all-consuming crush on her ArchEnemy Marinette.

* The ''WesternAnimation/KimPossible'' fic "[[https://www.fanfiction.net/s/3384624/1/Match-Ado-About-Nothing Much Ado About Nothing]]" features another villain's warped obsession with the idea of Kim and Shego being together driving her to turn Kim and Shego gay. Since Kim still loves Ron but can't be with him physically, Ron ultimately accepts it when Shego and [=DNAmy=] turn him into a woman with a Genetic Resequencer so that they can continue as a couple.

* A rather odd example in the ''LightNovel/FateZero'' parody fic ''[[https://m.fanfiction.net/s/11896019/10/ Fate Crazy Knights]]'' which has Arturia able to summon her Knights of the Round (minus Lancelot, who is summoned as Kariya's servant) and Merlin. Initially, the knights Gareth and Galahad start out male. However, following the release of the Camelot chapter in ''VideoGame/FateGrandOrder'', all the Knights that debuted or were talked about in that singularity undergo character updates in chapter 10, leading Gareth to become a girl and Galahad to fuse with Mash (who is fused with his power in the game). While Merlin is able to turn Galahad back to normal, he can't do the same to Gareth because she doesn't mind being a girl, especially since she can become Gawain's favorite little sister instead of competing with Gaheris for the role of favorite little brother.

* In the ''LightNovel/HaruhiSuzumiya'' fanfic ''[[https://www.fanfiction.net/s/5453599/3/Kyonko-s-New-Life Kyonko's New Life]]'', Haruhi causes two universes where the cast are [[GenderFlip opposite genders]] to merge, resulting in those in the know of TheMasquerade switching minds with their [[GenderFlip alternate selves]]. Our poor OrdinaryHighSchoolStudent and CosmicPlaything Kyon is now a girl with ACupAngst who still has to deal with the ever insane and domineering alternate universe Haruki.

** In Epilogue 2, [[Franchise/CthulhuMythos Nyarlathotep]] becomes [[LightNovel/NyarukoCrawlingWithLove Nyarko-san]]

* In ''[[https://www.fanfiction.net/s/3872674/1/Account-Transfer Account Transfer]]'', [[Manga/RanmaOneHalf Ryouga]] has his original curse overwritten with one that causes him to turn into a girl as part of his wish to have Ranma's problems.

* In ''[[http://www.fanfiction.net/s/8092152/1/Blessing-In-Disguise Blessing in Disguise]]'', a ''Franchise/SpiderMan'' fanfic, the radioactive spider who bites Peter Parker is female, which results in Peter not only gaining spider powers, but turning into a girl.
* One of the main characters of ''FanFic/BoyScoutsOneHalf'', Matthew Atanian, fell into the same cursed spring as Ranma and thus has the same curse. A later introduced character, Perfume, is a woman who fell into Spring of Drowned Boy, and thus has the inverse curse.

* There are several fan-written sequels to the "Claire Kent: Super-Sister" ''ComicBook/{{Superboy}}'' comic book story (see above). In these stories, Clark's transformation into Claire is ''not'' AllJustADream. The first story in the series can be read [[http://www.fictionmania.tv/stories/readtextstory.html?storyID=3355098155346635372 on this Website]].

* In ''[[https://www.fanfiction.net/s/13740751/1/Distorted-Reflection Distorted Reflection]]'', a battle with a D'arcmon damaged both Taichi's and Mimi's digivices. When they wake up the next morning, they find themselves in the opposite gender thanks to the damaged Digivices swapping data. The more they use their Digivices, the more they get repaired and in turn make it harder to return to their original genders.
** While their partners Agumon and Palmon remain the same, it's their ''Digivolutions'' that are affected. Agumon now digivoles into the female Sunflowmon, while Palmon digivoles into the male Growlmon.

** Harry doesn't seem overly bothered by the idea of doing it himself. In the sequel, he jokingly speculates about transforming Clark into a girl to fool the targeting on a magic spell, noting that a gender-switch ''is'' a big change. A mortified Clark shuts him down, and asks, essentially, "how would you like it?" Harry's dry response is that given what [[MostCommonSuperpower he knows about his cousins]], Jean and [[spoiler: Maddie]], and [[BuxomIsBetter has heard about]] his mother, he'd ask to change into a looser shirt first.
