->''"I'd make a sexy chick!"''
-->-- '''Brodie''', ''Film/{{Mallrats}}''

''For every given male character, there is a female version of that character, and vice versa.''

They may be canonical. Most of them aren't. The internet has a fascination for producing [[GenderBender gender swapping]] regardless of the context of the original character. Canon-derived examples of the trope tend to outlast their actual-canon inspirations (which are often single stories, or even short throwaway gags.)

No character is immune to this effect -- not [[Franchise/StarWars Darth Vader]], not [[Franchise/{{Halo}} Master Chief]] - no one. [[note]]Not even ChuckNorris. [[RulesOfTheInternet Rule 61 lied to you.]][[/note]]

Closely related to GenderFlip. When a ''separate character'' is a female knock-off of an existing male character, you have a DistaffCounterpart. [[{{Crossdresser}} Crossdressers]], of course, provide their own version of this. There's a good chance that you'll see the character in question in a GenderedOutfit (like our lovely Maria at right, here).

One of the RulesOfTheInternet. Can (and often does) overlap with [[RuleThirtyFour Rule 34]]. Since these female versions are often much cuter than their male counterparts, it can also overlap with SelfFanservice.

!!Examples

[[foldercontrol]]

!!Distaff Counterpart/Gender Flip
[[folder: Anime And Manga]]
* ''Manga/AxisPowersHetalia'', [[AnthropomorphicPersonification as a series where gender is essentially an arbitrary distinction]], actually has official art fulfilling this rule.
* A canonical example for Yu-Gi-Oh! would be the Dark Magician Girl that appeared in the Battle City arc.
* ''Anime/CodeGeass'' Mao in the AlternateUniverse series ''Manga/CodeGeassNightmareOfNunnally'' is one of these. In the regular series, he was a dude Lelouch's age. In the spinoff, she's a girl Nunnally's age.
* ''Manga/MahouSenseiNegima'' literally has a RuleSixtyThree in regards to [[spoiler: Fate, and her name is Sextum because she's the 6th Averruncus series.]]
* According to the backstory of [[VisualNovel/FateStayNight Fate/Stay Night]], [[spoiler:Saber]] is a gender-flipped version of [[spoiler:KingArthur]], who pretended to be male during her life, with some help from [[spoiler:Merlin]].
* Parodied in the anime version of ''Manga/CromartieHighSchool''. The first half of the last episode is devoted to reusing jokes from the beginning of the series, but with the central cast's female versions, who have the exact same voices and unattractive faces as their male counterparts. (Fanart of these versions is very rare.)
[[/folder]]

[[folder:Comic Books]]
* [[Franchise/TheDCU DC Comics]] actually has an AlternateUniverse devoted to this: Earth-11, featuring [[Franchise/{{Superman}} Superwoman]] and [[Franchise/{{Batman}} Batwoman]] as well as the very [[Film/ThreeHundred Spartan-looking]] [[Franchise/WonderWoman Wonder Man]].[[note]]([[Creator/MarvelComics no relation]])[[/note]] Fun fact: 11+[[ComicBook/FiftyTwo 52]] (the total number of alternate Earths after ''InfiniteCrisis'') equals... ''63''.
* DC's {{Animesque}} ''Toys/AmeComiGirls'' line has female versions of many male characters, but not vice versa, and not for all male characters. Most are actually the {{Distaff Counterpart}}s of the male characters, "promoted" in their absence. But there are a few straight examples of this trope, including a female Sinestro, and an Indigo made indistinguishable from a female Brainiac.
* MarvelMangaverse: Characters who don't start the story off already female are replaced by females very quickly.
* One comic had TheAuthority meet their gender-flipped AlternateUniverse selves.
* The ComicBook/FantasticFour once visited an alternate universe where [[ComicBook/IronMan Tony Stark]] was female... and [[HoYay married to Captain America]].
* An issue of ''Uncanny ComicBook/{{X-Men}}'' featured an evil team of male versions of several X-Women fighting Captain Britain. Most of them looked very flamboyant in those costumes.
* Comicbook/{{Exiles}} once visited an alternate Earth with female Magneto and Quicksilver, and Scarlet Warlock ([[CaptainObvious male Scarlet Witch]]).
* SelfDemonstrating/TheJoker:
** He's a woman named Bianca Steeplechase in ''Thrillkiller'' and its sequel, which are set on an alternate Earth in the early '60s. ComicBook/{{Batgirl}} and Robin goes up against her. [[GirlOnGirlIsHot Harley Quinn is still a girl.]]
** In the''Flashpoint'' arc, the shots in Crime Alley that night killed Bruce. There's still a Batman; though; Thomas Wayne would up becoming the [[DarkerAndEdgier (really) Dark Knight]] as a result. The Joker exists too, as a direct consequence of the same evening: [[spoiler:Martha.]]
* ComicStrip/DennisTheMenaceUK had a female cousin who looked exactly like him but wore a bow in her hair and a skirt. Also her name was Denise The Menace.
* The cover of issue #8 of the second volume of ComicBook/YoungAvengers depicts the main team as how they look in many alternate universes. One of them is a universe where all the female characters are male and viceversa. The section showing that universe is rather tiny but at least fans of male Kate Bishop won't have to adapt the character anymore (and fans of female Prodigy at least know she has short hair like her male counterpart).
* ComicBook/{{X-23}} is pretty much an {{invoked| Trope}} version of this: A female clone created by a project attempting to recreate [[{{Wolverine}} Weapon X]], but because the genetic sample was too badly damaged on the Y chromosome, the scientist who created her decided to double the X and make the clone female, instead.
** Of course, that's not to say that Rule 63 versions of Wolverine weren't popular in fanart even ''before'' her creation...
* ''Franchise/StarTrekExpandedUniverse'':
** The ''Series/StarTrekTheOriginalSeries'' comic ''All of Me'' had a brief appearance via NegativeSpaceWedgie of one Jane T. Kirk, captain of the Foundation starship ''Enterprise''.
** The comic book series based on the 2009 film eventually introduced an alternate universe containing gender-swapped versions of the entire ''Enterprise'' crew, complete with a version of Jane Kirk.
[[/folder]]

[[folder:Fan Works]]
* One of the topics for [[http://sto-forum.perfectworld.com/showthread.php?t=1118521 Literary Challenge #64]] on the ''VideoGame/StarTrekOnline'' forums was to write a story where your captain ended up in a gender-flipped universe via a NegativeSpaceWedgie.
[[/folder]]

[[folder:Literature]]
* The anthology ''Star Trek: The New Voyages'' contains the story "Procrustean Petard", in which a NegativeSpaceWedgie gender-flips the crew of any starship that comes within range (except for the strongest male aboard, who gets an extra Y chromosome).
* From ''Literature/TheElderScrollsInUniverseBooks'', ''[[http://www.uesp.net/wiki/Lore:The_Sultry_Argonian_Bard,_v1 The Sultry Argonian Bard]]'' is a gender-flipped SelfInsertFic of ''[[http://www.uesp.net/wiki/Lore:The_Lusty_Argonian_Maid The Lusty Argonian Maid]]''.
[[/folder]]

[[folder:Live-Action TV]]
* ''Series/RedDwarf'' had an entire alternate dimension where Lister, Rimmer, and Holly had female counterparts; Cat, meanwhile, had a male dog counterpart. Because [[FemaleFelineMaleMutt dogs and cats are different genders]].
* Pops up every now and then on ''{{Sliders}}'', Most notably in the episode Double Cross where there is a female counterpart of Quinn named Logan St.Clair.
* The sketch TV show ''Series/InLivingColor'' had Kelly Coffield as Andrea 'Dice' Clay.
[[/folder]]

[[folder:Tabletop Games]]
* TabletopGame/YuGiOh: Here's [[http://yugioh.wikia.com/wiki/Fabled_Dianaira Fabled Dianaira]] Its name might come from 'Deianira' in the Greek mythology. Ironically, Deianira is a female while this card is obviously male. However, a fanartist [[http://www.pixiv.net/member_illust.php?mode=medium&illust_id=9569358 "corrected"]] this mythological error.
[[/folder]]

[[folder:Video Games]]
* ''LostSaga'' not only loves to include ''VideoGame/BlazBlue'' characters into its game, but also allows you to buy an item that lets you play as a female version of that character, examples include [[http://www.youtube.com/watch?v=UeVmx2wxRic Ragna]] and [[http://www.youtube.com/watch?v=znNbeZ4jDDc Hazama]], [[http://www.youtube.com/watch?v=0Z4N1e9Ai30 Jin]] is the only exception as his female version is Noel Vermillion.
* There are genderbent chibi figures of several famous ''Franchise/MetalGear'' characters. These are an official product distributed for nothing more than fanservice. Snake is rather cute...
* An official version in ''VideoGame/SuperRobotWarsReversal'' in the case of Raoul[=/=]Fiona Gureden. Fiona is basically Raoul as a girl (and vice versa). In ''[[VideoGame/SuperRobotWarsOriginalGeneration Original Generations]]'', they decided to keep both branches and make them HalfIdenticalTwins.
* ''KoihimeMusou'', an [[{{Eroge}} erotic game]] based on ''TheRomanceOfTheThreeKingdoms'', in which most of the novel's male characters are female.[[spoiler: Diao Chan is now a muscular man ''in bikini'', voiced by NorioWakamoto.]]
** So are ''SengokuRance'' (partial example, as many characters remain in their original gender, e.g. UsefulNotes/OdaNobunaga) and ''Sengoku Hime'', with the UsefulNotes/SengokuJidai as backdrop.
* In ''VideoGame/AuraKingdom'', for some odd reason, the Eidolons based off of the archangels are all female.
[[/folder]]

[[folder:Western Animation]]
* ''WesternAnimation/GeneratorRex'' has an awesome in-universe example of this in "Beyond the Sea," although the similarities between the Cabo Luna beach babes and Rex and Noah go unnoticed. [[http://green-necklace-girl.deviantart.com/art/Gen-Rex-Motivational-199154975 Yay for surprise fanservice!]]
* ''WesternAnimation/{{Metalocalypse}}''. Dethklok had a tribute band that was composed of all women, giving each of the band members a female counterpart. Dethklok rejected them, as they found them rather creepy. Though Toki admits the female Pickles was cute, and Nathan agreed she did have nice eyes.
* ''WesternAnimation/{{Superjail}}'' had an early episode where opposite-sex counterparts of the staff ("Ultraprison") appear along with a bunch of female inmates, complete with a [[SpearCounterpart transgender man]] to compliment Alice. These characters would be reused for a cameo at the end of season 2, setting up a cliffhanger for the following run of episodes. Within season 3, the Ultraprison characters appeared again in the premiere, while two other episodes had brief cameos. The cliffhanger for season 3/premiere of season 4 also revisit this concept yet again.
* The episode "Adventure Time with Fionna and Cake" used this concept, and in a reference to this trope, [[spoiler: the entire episode was revealed to be a fanfiction by Ice King.]]
** Another episode, "Bad Little Boy", shines focus on some more gender-swapped characters.
* "Neutopia", the seventh season premiere for ''WesternAnimation/{{Futurama}}'', features GenderBender versions of each character. The episode even lampshades this trope when a calendar of the sex-changed characters makes a huge profit due to the "creepy fans" of Planet Express.
** Also, Coilette, Bender's attempt to join (and win) the 3004 Olympics as a bending competitor, in "Bend Her"
* [[OppositeSexClone In-universe]], [[ThePsychoRangers the Rowdyruff Boys]] to WesternAnimation/ThePowerpuffGirls.
* In an early episode of ''WesternAnimation/YoungJustice'', Miss Martian uses her shape-shifting powers to imitate Kid Flash, Robin, and Aqualad -- but female versions, because her powers aren't developed enough to readily do more complex shape-shifting stunts such as mimicking the opposite sex. [[http://www.youtube.com/watch?v=VMUas9j0h1Q Kid Flash approves.]]
* ''FamilyGuy'' has an in-universe example. In a CutawayGag, Peter and Lois agree to make out in one of the restaurant bathrooms. When Peter comes out of the bathroom thanking Lois, she says she didn't go in with him. The person who he made out with turns out to be a male clone of Lois, who sits at a table with a female clone of Peter.
* ''FostersHomeForImaginaryFriends'': An in-universe example occurs in "Destination Imagination", in which Mr. Herriman hires several potential replacements for Frankie when she disappears, one of them being basically a male Frankie.
[[/folder]]

[[folder:Webcomics]]
* ''Webcomic/MenageA3'':
** Although "Garii" is just a figment of Yuki's imagination, she's close enough.
** There's also an "official" manifestation of this trope as a bonus story in the series' fourth book collection.
* ''Webcomic/ScandinaviaAndTheWorld'' has a male and female version of most commonly mentioned countries; they are generally very similar in appearance. (Sister Germany even has her brother's mustache).
* Many characters in ''ArthurKingOfTimeAndSpace'' have different genders based on their arc. Tristram, in particular, is female in every arc besides the baseline, and Morgan and Nimue are actually ''male'' in the M*A*S*H* arc.
* ''Webcomic/ElGoonishShive'' has a great deal of actual GenderBender activity, which also inspires a lot of fan art.
* [[http://www.kevinandkell.com/2007/kk0401.html This]] AprilFools strip of ''[[KevinAndKell Kevina And Kelly]]''
* An official version of this occurs in ''Webcomic/EarsForElves''. The last panel [[http://www.earsforelves.com/archives/388 here]] calls the rule by name and shows what Tanna and Luero would look like when gender-flipped.
* WebComic/{{Jix}} has a story arc that revolves around a device that might as well be called "The Rule 63 gun." Lauren spent the majority of the arc as a feminine looking man.
* Webcomic/UnwindersTallComics: Amy drew a picture of [[http://tallcomics.com/?id=125 BBQ She-Sauce]] and Unwinder [[StupidSexyFlanders finds that she's attractive]].
* The art gallery of the ''Webcomic/{{Eatatau}}'' website contains [[http://subcultura.es/webcomics/eatatau/arte_5043.jpg this]] gender-flipped picture of the two leads.
[[/folder]]

[[folder:Web Original]]
* Played with in ''RedVsBlue'': In addition to the six inept, clueless, lazy, and outright retarded men, who because of the series being a {{Halo}} machinima all look identical with only different color, there is a single female character in the form of Tex, who is almost completely sane in comparison and a more capable soldier than all the others combined.
** Later, (Griff's) [[EveryoneCallsHimBarkeep Sister]] is introduced, who is [[BrainlessBeauty as dumb as Caboose but insanely hot]]. [[InformedAttractiveness At least so we are told.]]
* ''The WebAnimation/{{RWBY}}'' series has an entire team composed of genderflips of legendary figures: [[JeanneDArchetype Jon of Arc]], Disney/{{Mulan}}, NorseMythology/{{Thor}}, and [[Film/{{Troy}} Achilles]].
[[/folder]]

[[folder:Real Life]]
* Among Mixed Martial Arts fandom, Cristiane "Cris Cyborg" Santos is considered to be [[BruiserWithASoftCenter Wanderlei Silva's]] female counterpart.
[[/folder]]

!!Gender Bending/Cross-Dressing
[[folder:Anime And Manga]]
* ''Manga/{{Naruto}}'' examples:
** The title character's sexy jutsu.
** Konohamaru uses it too.
* ''Anime/{{Pokemon}}'' has several prominent examples:
** In the first season, Ash Ketchum dressed up as 'Ashley', a little blonde girl in an orange dress.
** Ash has been forced to cross-dress once each region after this--as a one-shot female NPC in Hoenn, and as a FrenchMaid in Sinnoh. The fandom took these examples and ran with them.
** The banned episode "Beauty And The Beach" features James entering a swimsuit contest with inflatable breasts.
* ''Anime/CodeGeass'':
** Lelouch is forced into a dress in one Picture Drama, and into an incredibly skimpy belly dancer uniform in another. As a result, the fandom ''really'' likes to run with that idea.
* ''Manga/BlackLagoon'' does the gender inverting in one of its specials seen [[http://www.youtube.com/watch?v=BoSMtWykUq8 here on youtube]], including an awesome male Balalaika (and Eda looking an awful lot like the cowboy mercenary she had a GunKata duel with). Hilarity bonus also runs for the CreepyTwins. The best part is that, in spite of having their genders swapped, the characters ''still have the same voice actors'', who make ''no attempt to sound more gender appropriate''.
* BlueExorcist: Recently, creator Kato Kazue posted on Twitter sketches she made of the [[https://pbs.twimg.com/media/BNsxCFDCIAAiPiC.jpg:large main]] [[https://pbs.twimg.com/media/BNsxMPtCEAAyP8c.jpg:large cast]] [[https://pbs.twimg.com/media/BNsxa_PCUAA54i3.jpg:large gender]] [[https://pbs.twimg.com/media/BNsyCN3CYAAcILA.jpg:large swapped]].
* A recent chapter of the ''Manga/SoulEater'' manga made this canon. Most of the main characters (including Blair, but sadly, not Kid) became gender-swapped. How long a character stayed in his/her gender-bended form depended on how much of a CovertPervert that character is.
** Then again, there's still ''one'' [[AmbiguousGender character]] that seems immune to RuleSixtyThree. Then again...
* Hayate of ''Manga/HayateTheCombatButler'' was found to play a very convincing female (even attracting the romantic attention of three male characters in that form). His female appearance has since made several more appearances and its own name (Hermione Ayasaki) and Hayate has been fandom-paired with his gender bent form.
* Ren/Run from ''Manga/ToLoveRu'' can somehow change genders by sneezing. Lala also invents a device that temporarily causes someone to switch genders.
* The title character of ''Manga/RanmaOneHalf'' is a canonical GenderBender, being cursed to change into a sexy, female version of himself on contact with cold water, because he was once tossed into a cursed spring in a training session by his idiot father. While obviously a "real" aspect of the Ranma character, fandom has taken the concept even farther, naming the female side of him "Ranko" and making her an actual character in countless fan works, ([[RuleThirtyFour many of them extremely NSFW]]).
[[/folder]]

[[folder:Comic Books]]
* An issue of {{Lobo}} has the Main Man dying and going to the afterlife... only to be reincarnated as an extremely masculine female version of himself.
* A canonical ComicBook/{{Superboy}} story, "Claire Kent, Alias Super-Sister"[[note]]''Superboy'' #78 (1960)[[/note]] has Superboy transformed into a girl. It's not permanent ([[spoiler: and, as it turns out, the whole experience was just a mental illusion]]), and the story is mostly forgotten today, except as a tryout of sorts for the ComicBook/{{Supergirl}} concept. ''Mostly''. There is quite a lot of fan art, and several FanFics, based on the premise that Clark was permanently stuck as Claire.
[[/folder]]

[[folder:Live-Action TV]]
* ''Series/StarTrekTheOriginalSeries'', in its last-aired episode, "[[Recap/StarTrekS3E24TurnaboutIntruder Turnabout Intruder]]", tells the story of a forced BodySwap between Captain Kirk and his crazy ex-girlfriend Janice Lester. Of course, everything is sorted out at the end... though that hasn't prevented a plethora of FanFics, fan art, and photo manipulation about alternate scenarios where Kirk is stuck permanently in Janice's body (usually due to Janice-in-Kirk's-body being killed.)
[[/folder]]

[[folder:Video Games]]
* In ''VideoGames/OcarinaOfTime'', Zelda goes in disguise as Sheik, a very masculine version of herself.
* ''VideoGame/FinalFantasyVII'''s Cloud and [[NamesToRunAwayFromReallyFast Sephiroth]] are already [[{{Bishonen}} very pretty]]. The former was even forced to cross-dress once. [[http://danbooru.donmai.us/post/show/601476/ Guess what happened?]].
* [[http://i39.tinypic.com/qysv8n.jpg Iori Yagami]] of ''VideoGame/TheKingOfFighters''. SNK's acknowledgement: by courtesy of [[VideoGame/{{Darkstalkers}} Demitri's]] [[SNKVsCapcom Midnight]] [[GenderBender Bliss]] [[http://www.youtube.com/watch?v=sJtIk9z7TN0#t=0m7s here]]. Also, Gals Fighters (''Queen Of Fighters'') has a character called Miss X. [[spoiler:She's Iori dressed as a woman.]] Oh, and Orochi Iori's blissed form is [[spoiler:Miss X too!!!]].
* ''VideoGame/ShovelKnight'' plans to handle this in a unique way by creating an entire MODE for it. "Gender Swap Mode" will flip the gender of every main character, from the protagonist, to the bosses, to the BigBad herself.
[[/folder]]

[[folder:Web Original]]
* In-universe of the ThatGuyWithTheGlasses, a female version of WebVideo/TheNostalgiaCritic (the title card version) was dressed like a sultry-looking hooker for his review of ''MoulinRouge''.
[[/folder]]

[[folder:Western Animation]]
* One particularly nice example of the ''WesternAnimation/{{Metalocalypse}}'' band getting genderbent exists [[http://aznmodel.deviantart.com/art/Chicklok-56217431 here.]]
* The fandomís tendency to swap genders for the characters of [[WesternAnimation/MyLittlePonyFriendshipIsMagic MLPFIM]] is played with in "Magic Duel": Twilight Sparkle transforms Applejack into a stallion for a short time for a competition on who has better magical ability. [[spoiler: It's later revealed that it was actually her brother painted in Applejack's mane and coat colors]].

[[/folder]]

!!Fanverse
[[folder:Anime And Manga]]
* [[http://haldo6.deviantart.com/#/d38njyb Bakura has been struck!]] [[WebVideo/YuGiOhTheAbridgedSeries After all, "There are no women in Yu-Gi-Oh..."]]
** Jonouchi's [[http://yamitomangaka.deviantart.com/#/d45zfpo been treated like this as well]].
* Naruto's sexy jutsu: "Naruko" is considered an entirely separate character by many fans.
** [[http://i44.tinypic.com/14tr2n4.png "Sasuko"]] is also susceptible to this.
** [[DudeLooksLikeALady Haku]], who appeared early in the Manga (and again much later). A large portion of the community (especially FanFic writers) seems to like the idea of Haku actually being a girl, either omitting the one actual indication of his gender or just simply having Haku and Zabuza lying about his gender.
** ''Fanfic/ProjectNaruko'' {{Gender Flip}}s the entire universe of ''Naruto''.
* In response to a fan letter, Creator/EiichiroOda of ''Manga/OnePiece'' fame drew [[http://danbooru.donmai.us/post/show/570908/ reverse-gendered]] versions of the main cast in chapter 545's SBS Corner. This has spread like wildfire among ''One Piece'' fans -- try finding ''any'' characters that haven't been gender flipped. Not even {{Big Bad}}s are immune -- Crocodile? [[http://danbooru.donmai.us/post/show/596577/ Nope.]] [[AGodAmI Enel?]] [[http://danbooru.donmai.us/post/show/614418/ Nuh-uh.]] [[WakeUpCallBoss The three Marine admirals?]] [[http://danbooru.donmai.us/post/show/612154/ Seriously, NO EXCEPTIONS.]] (Images are [[NotSafeForWork NSFW]].) This goes so far as to include [[http://3oct1111.deviantart.com/art/Thousand-sunny-TG-198196406 The Thousand Sunny]]. Then we get Ivankov, whose canonical powers ([[GenderBender gender bending]]) not only mean that he/she can do this to him/herself, but to other people as well. Did we already mention Crocodile? Comes from the crazy theories of his third weakness, but it's gotten to the point where there's stuff that isn't just the character [[GenderFlip gender flipped]] anymore.
* The aforementioned 'Ashley' from Pokemon is ''still'' drawn by the fans, has her own fan clubs, and some people consider her a different character.
* Pokemon: Guess what ''else'' has lots and lots of fanart.
** [[ScrewYourself Ash/Ashley]]. Yes, [[RuleThirtyFour it exists]]. Wouldn't be surprising if there was also Ashley/Ashachu or Ashley/Ash/Ashachu [[labelnote:*]](Ashachu = Ash turned into a Pikachu)[[/labelnote]] out there.
*** [[http://wingedspiritfox.deviantart.com/art/Ash-s-Pikachu-as-a-Girl-329314393 And apparently, yes, it is out there.]]
** Hun, a Team Rocket member from ''Anime/TheLegendOfThunder'' special was (a very girly) [[ShesAManInJapan male in the Japanese version.]] Guess who didn't get the memo about his gender. 4Kids.
*** Although he's never referred to as "she", and is often considered by fans just to be a man with a very feminine voice. However, the Latin American Spanish dub repeatedly calls him a woman.
* ''LightNovel/{{Baccano}}'' character Claire Stanfield has a sadly feminine name,right? [[http://www.pixiv.net/member_illust.php?mode=manga&illust_id=14534972&type=scroll Here]], the name fits the character better. Fem!Graham is on that page, too, as is [[FemmeFatale Chane]] [[CuteMute Laforet]] as a [[SharpDressedMan well dressed]], TallDarkAndHandsome {{Bishonen}}. [[MrFanservice *Dreamy sigh*]]. Curiously, Ladd Russo and Christopher are on that page too, but they're completely unaffected.
* From this page's counterpart on the /tg/ wiki, I give you [[http://1d4chan.org/images/thumb/3/33/GoldenRule.jpg/480px-GoldenRule.jpg Eduarda Elric and Rowena Mustang]]. Our poor [[Manga/FullmetalAlchemist title character]] doesn't seem too comfortable with that outfit, despite the fact that no [[MemeticMutation tiny miniskirts]] are involved.
** Maybe she's just wondering [[FridgeLogic why she got her leg back]]?
* Befriending people (through giant energy blasts or otherwise) is now twice as easy with [[MagicalGirlLyricalNanoha Nanoha's]] [[http://danbooru.donmai.us/post/show/737987/ male self!]]
** [[http://danbooru.donmai.us/post/show/737977/ Nanoha x Nanoha]] [[ScrewYourself OTP?]]
* Through the magic of pitch-adjusting technology, many of the ''[[KOn K-On!]]'' songs have been gender-flipped. As have the main four characters. Azusa doesn't seem to be gender-flipped yet since they seem to have been made before she was introduced. [[http://www.youtube.com/watch?v=R2LhKmsy_M0 Here's]] the Season 1 opening (Cagayake! Boys), and the rest can be found [[http://metanorn.net/2009/05/k-on-genderbender/ here]]. The real kicker? [[CrowningMusicOfAwesome It's actually pretty darn good.]] And then there's the fact that the K-On girls themselves are essentially gender-flipped versions of TheBeatles.
* [[ImageBoards 4chan]] is already doing this with ''Anime/PuellaMagiMadokaMagica'', with Madoka being a Rose-Haired Boy, Mami looking like a prince, and Homura as a long-haired {{Bishonen}}.
* ''[[FanFic/SuzumiyaHaruhiNoSeitenkan The Genderbending of Haruhi Suzumiya]]'' does this to the ''LightNovel/HaruhiSuzumiya'' cast, and the "new characters" it created are permanently entrenched in the fandom. "Kyonko" in particular is probably more popular than the male Kyon, and is paired with ''[[LauncherOfAThousandShips even more]]'' characters than him.
* There's also the fanfic ''Fanfic/NerimaMagistraNellyMagi'', which was an attempt to GenderFlip the ''Negima'' manga without the result being [[UnfortunateImplications "too creepy"]].
* ''Manga/DragonBall'' examples can be seen [[http://starrdust411.deviantart.com/gallery/8827971 here]], [[http://www.fanfiction.net/s/4333729/1/Journey_to_the_East here]], and [[http://danbooru.donmai.us/post/show/757661/artist_request-barefoot-belt-boots-dragon_ball-dra here]].
* ''Anime/MobileSuitGundam00'' recently got a lot of such art, mainly directed at [[DudeLooksLikeALady Tieria]] but no one is immune: the Gundam meisters, Graham, Billy, Patrick... even the [[AnthropomorphicPersonification Gundams themselves]].
* [[TheBechdelTest Alas it seems only with this will you find]] a {{badass}} woman in the ''Manga/DeathNote'' fandom.

* A particular [[http://www.figure.fm/en/post/13533/Gender+Bender+Friday+Jul+16+2010.html fanart]] (second image down) of HigurashiNoNakuKoroNi actually spawned some discussion on what a gender-flipped version would be like... before someone pointed out that this [[DoubleStandard would]] make Male![[ImTakingHerHomeWithMe Rena]] into a guy who regularly kidnapped children and gushed about how they were 'cute.' The conversation was more or less sunk after that.
* There is a meme among ''Anime/NeonGenesisEvangelion'' fans that gender-flipping the cast would actually make them fit their roles much better, [[http://i.imgur.com/XGGNYRy.jpg mostly the]] [[http://i.imgur.com/gA61YQr.png children]] and ''especially'' [[http://i.imgur.com/P0tAmKJ.jpg Shinji]]. It got even better once the Western fans found out that in one of the spinoff games, Fuyutsuki (who had a crush on Shinji's mom) actually dressed Shinji up into drag!

[[folder: Comic Books]]
* Genderbending ComicBook/{{Loki}} from ''ComicBook/TheMightyThor'' isn't that difficult to imagine since not only is he a shapeshifter normally, but he assumed Sif's form for several story arcs for the lulz. Princesses [[http://kazeki.deviantart.com/art/LADY-THOR-244700620 Thor]] and [[http://theladyloki.tumblr.com/ Loki]] aside, [[http://www.tumblr.com/photo/1280/balphesian/8448123007/1/tumblr_lpdlu8Dtvi1qk7ytl The Warriors Three]] have also enjoyed time as the fairer sex.
* [[http://fornax.tumblr.com/post/8423005240/experimenting-arrrrgh-but-now-its-time-for-bed The Avengers trio]], in a fan art depiction.
* ''ComicBook/{{Watchmen}}'' fandom has a fairly established body of Rule 63 fics, especially on the KinkMeme. Get used to Danielle, Wanda, Adi, Laurence, Joan Osterman, Sal and Edie.
* Common in fan art too, as a search for "Genderbent Joker" on Google will reveal. [[BrainBleach You may want to]] [[NotSafeForWork keep safe search on]].
* The ArchieComics gang, like most comic book PrintLongRunners, have attracted the occasional Rule 63 interpretations. A 2012 story, "The Great Switcheroo," provided official examples in ''Archie'' #636.[[note]][[MeaningfulName Meaningful Number]]?[[/note]] In the story, Comicbook/SabrinaTheTeenageWitch's cat Salem casts a GenderBender spell on the entire population of Riverdale, not to mention Comicbook/JosieAndThePussycats too.
* Behold, a [[http://kelly1-watxm.deviantart.com/art/Rogue-and-Gambit-Gender-Bender-53873558 sketch]] of genderswapped [[Franchise/{{X-Men}} Rogue and Gambit]]. This was met with enthusiasm, mainly because it would mean Gambit were a hot, flirty French chick.
* Brazilian webcomic creator Priscilla Tramontano has taken this rule and applied it to some of Marvelís most popular villains, and the results are absolutely [[http://comicscrux.com/priscilla-tramontanos-rule-63-villainesses-are-gender-flippin-fantastic/ glorious]]
[[/folder]]

[[folder:Fan Fic]]
* In ''[[FanFic/TheVinylAndOctaviaSeries Vinyl and Octavia Fight Ten Thousand Ninjas]]'', the climax reveals that [[spoiler:the leaders of the ninja clan are Rule 63 versions of Octavia and Vinyl Scratch from another universe.]]
[[/folder]]

[[folder:Film]]
* The 2009 ''Film/StarTrek'' has inspired GenderFlip fan art. For example, see a different take on the PowerTrio of Kirk, Spock, and [=McCoy=] [[http://lamamama.deviantart.com/art/Girl-Trek-Fierce-Times-Three-135312778 here]]. Chekov, Sulu, Scotty, and Pike show up [[http://lamamama.deviantart.com/art/Girl-Trek-PART-DEUX-136370157 here]]. [[http://oxboxer.livejournal.com/62530.html On this page]], we see that this trope can go in both directions.
** The tie-in comic book series played with this; see the Comic Books section.
* Not even [[Franchise/ANightmareOnElmStreet our]] [[Franchise/{{Halloween}} favorite]] [[Franchise/FridayThe13th slasher]] [[Franchise/{{Hellraiser}} movie]] [[Franchise/TheTexasChainsawMassacre kings]] [[http://wardog-zero.deviantart.com/gallery/#/d285ydg are immune to this rule]]
** Even better/worse, the upcoming ''[[http://www.fearnet.com/news/news-article/japanese-toy-company-teases-sexy-female-freddy-and-jason-statues?utm_source=Facebook&utm_medium=Newsfeed&utm_content=Sexy%20Jason%20Toy&utm_campaign=Genre%20News "Bishoujo Horror Series"]]''.
[[/folder]]

[[folder: Literature]]
* The 2013 ''Check These Out! Calendar'' of literary pin-ups by Lee Moyer includes [[http://www.discworldemporium.com/image/cache/data/books/Check%20These%20Out%20Rincewind-500x500.jpg a bikini-clad female]] [[Literature/{{Discworld}} Rincewind]] (approved by Sir Creator/TerryPratchett).
[[/folder]]

[[folder:Live Action TV]]
* A sketch on ''Series/TheCarolBurnettShow'' featured gender swapped versions of the cast of the original ''Series/{{Star Trek|The Original Series}}''.
* ''Series/SaturdayNightLive'' has a sketch called "What Up With That?" in which a cavalcade of groovy, costumed background folks help obnoxiously interrupt the guest's interview, whenever the host compulsively re-sings the theme song. Among them on the Christmas edition is "[[HowTheGrinchStoleChristmas Grinchina"]]. Played by Nasim Pedrad, she makes for a freaky but CuteMonsterGirl.
[[/folder]]

[[folder: Tabletop Games]]
* ''TabletopGame/{{Warhammer 40000}}'' examples:
** Cultist-chan shows up in many [[ImageBoards /tg/]] ''TabletopGame/{{Warhammer 40000}}'' memes. Now, meet [[http://1d4chan.org/wiki/File:Cultist-kun_by_Mr-Culexus.png Cultist-kun!]]
** [[http://1d4chan.org/wiki/File:Beakiegal.jpg Female Space Marines]] pop up now and again, but are often met with cries of CanonDefilement (also known as '''HERESY!''') due to a supplement which states that Space Marines are explicitly all-male.
[[/folder]]

[[folder: Video Games]]
* Partly thanks to the entire cast being male, a significant amount of ''VideoGame/TeamFortress2'' fanart/fanfiction is Rule 63. The most frequent target is TheChick, Medic. As stated below, ''NerfNow'' has them as characters.
** [=ChemicalAlia=] has a mod to replace the Scout, Heavy, Engineer, Medic, and Spy (with more coming) with female models and fan-made female voices.
** There are several mods for a female Pyro. [[AmbiguousGender Not a lot changes, really]].
*** Heck, people have been having fun with making exaggerated male ''and'' female Pyros, either with a HeroicBuild and firefighter suspenders (if male) or a toned body wearing a bikini top (if female). Since Pyro is also TheFaceless, both genders wear his/her full-face gas mask.
* Link from ''Franchise/TheLegendOfZelda'' gets hit ''hard'' with this, [[IAmNotShazam possibly because he gets called "Zelda" all the time]]. Also, Zelda herself, if to a lesser extent...
* "Tailsko," a female version of Tails, is likewise a popular subject for ''SonicTheHedgehog'' fan works.
* Fans don't even need to make them themselves for the bloodlines of ''BloodlineChampions'' - they all have an outfit which is the opposite gender of the original bloodline outfit.
* Even Altair from ''VideoGame/AssassinsCreedI'' had [[http://moe.imouto.org/post/show/57301/assassin-s_creed-thighhighs-uni-wallpaper one]]. Altair looks like [[SuzumiyaHaruhi Yuki Nagato]]; he just needs glasses. Shame they didn't exist back then.
* Sol Badguy of ''VideoGame/GuiltyGear'' has [[http://i43.tinypic.com/14lrhgi.jpg some]] [[http://i44.tinypic.com/1zx4a3o.jpg fan-art]]. Also there's the cosplayer known as [[http://i44.tinypic.com/6715ic.jpg Sol Badgirl]].
* From the same maker, ''VideoGame/BlazBlue'' experiences the same thing with female versions of [[http://www.giantbomb.com/ragna-the-bloodedge/94-7830/all-images/52-298458/ragna_by_humio/51-1040137/ Ragna]], among others.
* It's become surprisingly popular to depict ''VideoGame/{{MOTHER|1}}'''s big bad, Giegue, as a female. Since Giegue's a skinny grey alien, [[NonMammalMammaries some non-canonical anatomy]] comes into play.
** On the ''VideoGame/EarthBound'' end of things, we have [[http://artkitten.tumblr.com/post/10396828433/even-moar-earthbound-so-rule-63-earthbound Nell, Paul, Jess, Pu, Porkie, and Toni.]] (Definitely SFW)
** He is not the only one that suffers (or is very popular) due to this rule. In fact most of the ''KingOfFighters'' have been subject to this at some point or another (save Mai for some reason). But the one that gets it the most (even more than Iori) is Leopold Goenitz of the Wildly-Blowing Wind. Yes, [[SNKBoss that]] [[SinisterMinister guy]]... Oh and yes, [[VideoGame/{{Darkstalkers}} Demitri's]] [[SNKVsCapcom Midnight]] [[GenderBender Bliss]] is the one to blame for [[http://snk.wikia.com/wiki/Goeniko Goeniko]]. There are other characters based on this concept that simply run with the idea, and the {{Mugen}} fanbase tend to make a character out of this.
* Nobody's surprised to see ''VideoGame/TalesOfVesperia'''s Yuri Lowell genderbent a lot. Since, well... [[{{Bishonen}} y'know]].
* In addition to the depiction of Maria, [[http://www.pixiv.net/member_illust.php?mode=medium&illust_id=12434455 the pretty girl plumber at the top of this page]], {{Mario}} and friends have been frequent subjects for this trope. See Maria's sister [[http://i173.photobucket.com/albums/w74/MarioDS01/Super%20Mario%20Brothers/A_Different_Kind_of_Mushroom_by_fea.jpg Luisa]], for example. (As a bonus for straight males, the previous two examples feature "Grade A" ZettaiRyouiki.) There's also this [[http://fc04.deviantart.net/fs6/i/2005/068/e/1/Paper_Mario_tTYD__Gender_Swap_by_pixlem.jpg group shot]]. You might not ''[[TemptingFate want]]'' to see Bowser as a girl, [[http://i173.photobucket.com/albums/w74/MarioDS01/Super%20Mario%20Brothers/Final.jpg but you can]].
** Though Bowser as a man has certainly been drawn thinner in FanArt before, one would think a female Bowser would more likely be a BigBeautifulWoman.
** Futako, the artist who drew the top picture, has since drawn [[http://www.pixiv.net/member_illust.php?mode=medium&illust_id=24574621 both Mario and Luigi]] as females. She calls them the ''Super Mario Sisters''.
** One shouldn't forget the very much official Toadette.
** Gender flipping Mario and Luigi goes back to ''Videogame/TheGreatGianaSisters'' in TheEighties, possibly the first video game example.
* [[http://static.mmo-champion.com/mmoc/images/news/2010/march/ss975.jpg This]] ''VideoGame/{{Warcraft}}'' fan art piece.
* ''VideoGame/{{Touhou}}'' fandom, due to the ImprobablyFemaleCast and the FirstLawOfGenderBending, has relatively little of this considering the sheer number of fan works. Regardless, plenty of the LoadsAndLoadsOfCharacters [[http://danbooru.donmai.us/post/show/433254/ have been subjected to this]], including [[http://danbooru.donmai.us/post/show/844239/ Yuuka]], [[http://danbooru.donmai.us/post/show/821660/ Marisa]], [[http://danbooru.donmai.us/post/show/484424/ Parsee and Yuugi]], [[http://danbooru.donmai.us/post/show/781823/ Komachi and Shikieiki]], [[http://danbooru.donmai.us/post/show/763817/ Yukari and Reimu]], [[http://danbooru.donmai.us/post/show/638546/ the Tengu trio]], the ''IN'' [[http://danbooru.donmai.us/post/show/222796/ playable characters]], [[http://danbooru.donmai.us/post/show/590203/ the Scarlet Devil crew]], [[http://danbooru.donmai.us/post/show/394810/ and even]] [[TheOneGuy Rinnosuke]] (images are slightly NSFW due to advertisements). And the less said about [[MemeticMutation Cho-Marisa]], the better.
* [=PotatOS=] aka GLaDOS of ''VideoGame/{{Portal2}}'' fame has gotten this treatment too.
* Star Wolf of ''StarFox'' [[http://www.pixiv.net/member_illust.php?mode=medium&illust_id=19994242 as females]], by Fumicaworu. Creatively done, and Wolf's gender flip even looks vaguely like a cross between his character and Katt Monroe as a pink wolf.
* An odd in-game example in ''[[MondayNightCombat Super Monday Night Combat]]'': Unlockable uniforms turn Combat Girl and Megabeth into {{Cosplay}} female versions of the Engineer and Soldier, respectively, from VideoGame/TeamFortress2.
* On the ''VideoGame/DragonAgeOrigins'' front, we have [[http://enife.deviantart.com/art/Gender-Challenge-Ms-Alistair-180046045 'Ms Alistair']], as well as [[http://browse.deviantart.com/?qh=ßion=&q=female+zevran#/d3l21w3 'Madam Zevran']], male counterparts of [[http://ladyreddarkness.deviantart.com/art/Isabela-and-Aveline-Gender-Swap-279295281 Aveline and Isabela]], one of [[http://ladyreddarkness.deviantart.com/art/Merrill-and-Fenris-Gender-swap-278754881 Merrill and Fenris]] and yet another of [[http://mariahgem.deviantart.com/art/Miss-Fenris-207064451 Fenris]], possibly because he's quite the [[{{Bishonen}} effeminitely pretty character]].
[[/folder]]

[[folder:Webcomics]]
* ''NerfNow'' has produced female versions of all the ''VideoGame/TeamFortress2'' characters, as well as several characters from other games, such as ''{{Starcraft}}''. And they're all ''adorable''.
* Seeing as [[CrackPairing anyone and everything]] gets shipped together in the ''Webcomic/{{Homestuck}}'' fandom, this was inevitable. Gender-bent versions of Dave, John, and the Midnight Crew are particularly popular though.
* Fans of ''HannaIsNotABoysName'' have made sure that [[http://browse.deviantart.com/?q=hinabn%20genderbend&order=9&offset=0#/d2j7pbj Hanna]] isn't... well, a boy's name. And [[http://colorsoftuesday.deviantart.com/gallery/38780758?offset=24 everyone else too]]. [[http://www.deviantart.com/morelikethis/180792849 Fem Conrad]] is pretty much a fandom meme. And that's just the tip of the genderbent iceberg.
* Tumblr users really like making female versions of [[PennyArcade Gabe and Tycho]] (named "Gabbie" and "Tyche", respectively). Zeboyd even responded to it by adding a patch to ''[[PennyArcadeAdventures On the Rain-Slick Precipice of Darkness]] Episode 3'' that allows players to play as the gender-flipped Gabe and Tycho if they want.
[[/folder]]

[[folder: Web Original]]
* Examples from ''Website/ThatGuyWithTheGlasses'':
** Anne Onymous of ''TheWotch'' drew a [[http://annie13.deviantart.com/art/TGWTG-TGed-124469372 Worksafe image of]] Website/ThatGuyWithTheGlasses.
** At one point, there was also an amusing series of videos created by (female) TGWTG fans dressing up as their favorite (male) reviewers and demanding that the fandom fix this crackfic singularity gender bend... thing.
* For their crossover review of [[Film/SherlockHolmes]] (2009), Website/TheAgonyBooth's Sofie Liv and ''WebVideo/StuffYouLike'''s Sursum Ursa dressed up (and did the review) as Holmes and Watson.
* ''WebAnimation/HappyTreeFriends'' plays this differently depending on which side of the fandom you are looking at. Among Japanese fans, the characters that get genderbended the most often are the four originally female characters. Out of the boys, designing female Russell, Lumpy and possibly Flippy seems to be the most common, although it is easier to tell who never is bent. Most of the results from searching for genderbends by the western fandom are either Flippy as a woman or female {{copycat sue}}s based on him.
* Even ''LetsPlay/TheRunawayGuys'' get the female treatment. [[http://fav.me/d5qyiay If]] them dressed as WesternAnimation/ThePowerpuffGirls doesn't count then [[http://fav.me/d473ga3 this totally does]].
** LetsPlay/JoshJepson plays the role of [[VisualNovel/AceAttorney Maya Fey]] in [[http://fav.me/d4hzt4x this pic]] if that counts too.
[[/folder]]

[[folder: Western Animation]]
* There is an entire AlternateUniverseFic of ''WesternAnimation/EdEddNEddy'' where the entire cast is of the opposite sex. It's made by the same author who gave us ''Ed, Edd n Eddy Highschool''.
* The ''WesternAnimation/AdventureTime'' [[http://frederatorblogs.com/adventure_time/ blog]] posted a series of [[http://www.flickr.com/photos/84568447@N00/4866645301/ Rule 63 drawings]] [[http://www.flickr.com/photos/84568447@N00/4880921290/ by one of the]] [[http://www.flickr.com/photos/84568447@N00/4860628206/ concept artists]], much to the amusement of fans.
* Given the high female-to-male character ratio on ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', it was probably only a matter of time before male versions of the six main characters came out. A fan artist named [[http://trotsworth.deviantart.com/ Trotsworth]] has probably the most famous examples. There's even fics about it, such as [[http://www.equestriadaily.com/2011/05/story-63rd-rune.html The 63rd Rune]] and Fanfic/OnACrossAndArrow.
** If there's ever going to be a fic or discussion about the gender-bent characters, there's a host of accepted names. Twilight Sparkle is Dusk Shine, Rarity is Elusive, Fluttershy is Butterscotch, Rainbow Dash is Rainbow Blitz, Pinkie Pie is Bubble Berry, Spike is Spines (or Barb/Barbara), Discord is Eris, Celestia is Prince Solaris and Luna is Prince Artemis. Only Applejack remains the same.
* ''OsmosisJones'' fan art examples have been seen, including cosplay of a female Thrax.
* [[http://sue-chan.com/art4/thundercatty.jpg This]] piece of ''WesternAnimation/ThunderCats'' fanart will likely murder your childhood in an entirely worksafe way.
* The Fire Ferrets from ''WesternAnimation/TheLegendOfKorra'' [[http://rule63rules.tumblr.com/tagged/Legend-of-Korra as you've (probably) never seen them before.]]
* And now, ''WesternAnimation/TheSimpsons'' [[http://mrpr1993.deviantart.com/art/The-Simpsons-Gender-Bender-331046611 are victims of this.]]
[[/folder]]

[[folder:Other]]
* Every {{Vocaloid}} (including [[HalfIdenticalTwins Rin and Len]]) and almost every [=UTAUloid=] tend to have a genderbend. In the [=UTAUloid=]'s cases, many are made by the authors themselves. People have also edited their vocal files to create a masculine/feminine version of the characters.
* The [[http://andersson.elfwood.com/The-Female-Fellowship.2524406.html Female Fellowship]] - a counterpart to the lineup of heroes from ''Literature/TheLordOfTheRings''.
