History GenderBender / WesternAnimation

** In "The Boy Who Would Be Queen", Timmy becomes a girl after he mocks Wanda's idea of wishing to turn into one (to find the perfect gift for Trixie Tang), noting that he did say "I wish" and "girl." This does allow him to think like a normal girl; after some humorous jabs at him by his godparents, Timmy gets back at them by wishing they switched genders, becoming Cosma and Wando.

** An {{ambiguous|situation}} one happens in "[[Recap/TheFairlyOddParentsS4E7ABadCaseOfDiaryUh A Bad Case of Diary-Uh!". In an effort to mess up Vicky's beauty, he wishes for the makeup artist (female) to be a monster movie make-up artist. Said female makeup artist turns into a stocky man with an oddly CampGay sounding voice. It's unclear Timmy swapped the female make-up artist's gender or just replaced her with someone else.

** In "Mr. Right!", Timmy's wish to always be right turns him into a RealityWarper where anything he says becomes true. One of the things he does with this power is summon a burly male masked wrestler to beat up Francis the bully, when said wrestler screams "WHO'S THE MAN?" and Timmy answers "Not you!" he turns into a still very burly blonde woman in a pink floral dress and skips off happily. At the end of the episode, she reappears as Francis's new girlfriend, Nancy the wrestler.

** In "[[Recap/FuturamaS4E13BendHer Bend Her]]", Bender poses as a fembot to compete in the Olympic games, wins several gold medals, then has to have a sex change in order to pass the gender verification test. As the fembot "Coilette," Bender begins a relationship with the robot actor Calculon -- planning initially to marry and divorce him so she can take half his stuff. However, it turns out that Calculon is genuinely in love with Coilette, and prepared to give up acting to be with her. In the end, the crew helps Bender fake Coilette's death at the wedding so he can undo the sex change without hurting Calculon more than necessary.

** In "Mr. Right!", Timmy's wish to always be right turns him into a RealityWarper where anything he says becomes true. One of the things he does with this power is summon a burly male masked wrestler to beat up Chad the bully, when said wrestler screams "WHO'S THE MAN?" and Timmy answers "Not you!" he turns into a still very burly blonde woman in a pink floral dress and skips off happily. At the end of the episode, she reappears as Chad's new girlfriend, Nancy the wrestler.

* Bender from ''WesternAnimation/{{Futurama}}'' blurs the line between the "already ill-defined robot sexes" more than once:
** In "[[Recap/FuturamaS2E8RagingBender Raging Bender]]", he becomes a fighter for the Ultimate Robot Fighting league, and is first billed as "Bender The Offender"; as his popularity falls, however, he's forced to play the GorgeousGeorge {{Heel}} role of "The Gender Bender", dressed in a blonde wig and pink tutu.

** "[[Recap/FuturamaS6E20Neutopia Neutopia]]" brings the entire Planet Express crew to a planet where gender is unknown, and an alien swaps their sexes. Leela and Amy do not enjoy being male, while Fry, Bender, and the other men-turned-women find the experience fun. In a CallBack, Bender's female form is Coilette.

* ''WesternAnimation/TheAmazingWorldOfGumball'' episode "The Job" involved Richard's reality-warping shockwaves hitting the other Wattersons and Larry, who switch genders at one point.

* In the ''WesternAnimation/BatmanBeyond'' episode "Out of the Past", [[spoiler:it turns out Ra's Al Ghul has [[GrandTheftMe taken over his daughter's body]]]], which is even more disturbing than it sounds. Ra's can speak with his Ra's voice, even though he has the body of a woman... the transition is outright creepy. Furthermore, Ra's still acts in a very effeminate manner, despite the voice. Remarking on the situation:

** "Operation: F.U.T.U.R.E." has a young misandric lass who gets a "Girlifyier" gun from her alternate future self. Cue the dystopian alternate future, where Numbuh Four [[spoiler:(minus his hand)]] is the only adult male left. He becomes the leader of the Boys Next Door; with the help of Numbuh Three's granddaughter develops a "Boyifyier", and a sex-swapping battle ensues. [[spoiler:He manages to evade this future [[SetRightWhatOnceWentWrong by going back in time and changing things]].]]
** "Operation: C.A.R.A.M.E.L.", where Numbuh Five's candy-hunting rival, Heinrich von Marzipan, [[spoiler:turns out to have once been a girl, who was transformed into an ugly boy through some magic caramels which took away ''her beauty'']]. And this is the reason he has such a big grudge against Abby.

** In "Mr Right" Timmy's wish to always be right turns him into a RealityWarper where anything he says becomes true. One of the things he does with this power is summon a burly male masked wrestler to beat up Chad the bully, when said wrestler screams "WHO'S THE MAN?" and Timmy answers "Not you!" he turns into a still very burly blonde woman in a pink floral dress and skips off happily.

** In "Raging Bender", he becomes a fighter for the Ultimate Robot Fighting league, and is first billed as "Bender The Offender"; as his popularity falls, however, he's forced to play the GorgeousGeorge {{Heel}} role of "The Gender Bender", dressed in a blonde wig and pink tutu.
** In "Bend Her", Bender poses as a fembot to compete in the Olympic games, wins several gold medals, then has to have a sex change in order to pass the gender verification test. As the fembot "Coilette," Bender begins a relationship with the robot actor Calculon -- planning initially to marry and divorce him so she can take half his stuff.

** In "Prisoner of Benda", Amy and Professor Farnsworth use an AppliedPhlebotinum device to voluntarily [[FreakyFridayFlip switch bodies]] (she wants to binge eat without consequences, he wants to be young again). Once they try to switch back, however, they discover that the machine cannot be used on the same two people twice... leading to a barrage of body swapping [[HilarityEnsues hilarity]] that includes (but isn't limited to) Bender inhabiting Amy, Leela switching into the Professor's body, and Amy switching with Hermes.

* In ''WesternAnimation/JusticeLeagueAction'', when ComicBook/{{Superman}} is exposed to pink kryptonite he's turned into a woman (and an AmazonianBeauty at that, except his voice stays the same) instead of being turned gay. He doesn't seem to mind too much, although once it's resolved [[LetUsNeverSpeakOfThisAgain he asks Firestorm not to tell Batman]].

** "Operation: F.U.T.U.R.E." has a young misandric lass who gets a "Girlifyier" gun from her alternate future self. Cue the dystopian alternate future, where Numbuh Four [[spoiler:(minus his hand)]] is the only adult male left.

[[spoiler:He manages to evade this future by going back in time and changing things]].

* In an episode of ''WesternAnimation/OzzyAndDrix'', when Ozzy accidentally ends up in the body of a girl instead of his usual (for the TV show) human host Hector, Ozzy's own sex starts changing. He very nearly becomes completely female, but does not lose his beard.
