"Not her! Not her! She pees standing up!"Sexual attraction is a funny thing, and sometimes if a character physically appears to be the right gender to appeal to their sexual preference, then they'll become attracted to them, regardless of what that character's actual gender might be. Usually said character's true gender is being kept secret purposefully and they are a male Disguised in Drag or a female disguised as a male, but whether the misunderstanding was intentional or not, due to Rule of Drama, they will find out and it will be awkward, hilarious and possibly traumatizing for all involved. This can happen to any gender and sexuality. (Well, almost any. Actually, only monosexuals--bi people likely won't care.) A straight male might be shocked to find the girl he's been crushing on was a male all along. A straight female might be confused to realize that hot guy she's been daydreaming about was actually a woman. Her male Gay Best Friend, who was also daydreaming about the guy (who is really a girl) will probably feel similarly. Almost always there is shock upon The Reveal, probably disappointment and maybe even disgust on the part of the character who was feeling the attraction, but usually the two characters can reconcile by the end and become friends. Other times it might not bother them, or after a period of consideration, they'll decide If It's You, It's Okay. This is both a reveal trope as well as a character reaction trope, when what initially appears to be compatible gender attraction is later revealed to actually be incompatible gender attraction (Example: Straight boy likes a girl, girl turns out to be a boy). It is a sister trope to the related Sweet on Polly Oliver, which refers to when what initially appears to be inexplicable incompatible gender attraction is later revealed to actually be compatible gender attraction (Example: Straight boy likes a boy, boy turns out to be a girl), although since the unsettling part is averted, this is usually a subversion (usually). It's also worth noting that in many examples of this trope, it's not the gender (i.e., gender identity) that's a shocker, but the genitals. One common example is that a straight man is attracted to a woman but finds out that she's transgender and has a penis — in Real Life, "trans panic" can have violent or even lethal consequences, and numerous trans people (mainly trans women) being physically or sexually assaulted, sometimes even murdered, when their genitals are revealed. Compare with Shapeshifting Squick, Dude Looks Like a Lady, Lady Looks Like a Dude, Bifauxnen, Gender-Blender Name, Samus Is a Girl and Female Monster Surprise. Often accompanied by Attractive Bent-Gender. Contrast Jumping the Gender Barrier and She's a Man in Japan. A subtrope of Gender Reveal. Formerly called "Dropped A Bridget On Him", a play on the Guilty Gear character and the Dropped a Bridge on Him trope; references back to this title are still scattered around the site. Spoilered pronouns are by definition self-fulfilling, so don't bother doing that.

Anime & Manga
- Shugo Chara!: Nadeshiko/Nagihiko, whose family has a long-standing tradition of making its boys dress, act, and, for all intents and purposes, be girls for about the first twelve years of their lives. He had to repress all boyish desires, no matter how slight, and was forbidden from revealing his true gender to anyone.
- Jubei-chan 2. Dropped on the audience and on Jiyu, who spent the entire series thinking this person was either chibi spirit Koinosuke or reincarnated baby Koinosuke... only for it to end up being Koinosuke's never-before-mentioned daughter who looks exactly like him.
- School Rumble: Second Semester plays this straight at the end of the third episode. One of the characters present lampshades the moment beautifully.
"What... the hell?"
- In The Secret Devil-chan: Kurosaki Sou discovers this about Devil-chan, after just 10 pages into the manga.
- Ship Leesoo from Tower of God finds out that the Bull is a female by kicking it in the groin to no avail.
- Happens to people of both genders in Axis Powers Hetalia.
- Everyone in the surroundings of Chibitalia mistook him for a girl until he hit puberty. In this fan comic, Holy Roman Empire gets the Chibitalia bridge dropped on him.
- Hungary herself used to be so tomboyish that she was mistaken as a boy by her rivals, and she herself thought she was a boy due to chronic lack of sex-ed in these times. It wasn't until she was a teenager that other nations realized Hungary was a girl, starting with her old rival Prussia when he sees her badly beaten after a battle and notices that her blouse and armor are torn to Absolute Cleavage levels, much to his surprise.
- Also, Hong Kong used to be mistaken as a Bifauxnen, when in reality he's male.
- China. Then again, Dude Looks Like a Lady and has a girlish voice.
- At one point, Italy calls Germany for help because "There was a pretty girl, so I hit on her, but it turns out the pretty girl was France in disguise!" Since France has a noticeable beard, one has to wonder how Italy made that mistake. Then again ...
- Germany referred to Kugelmugel as a boy, much to Liechtenstein's surprise, though she reacts with confusion over why he calls "her" a male rather than shock.
- And even more amusingly, fans that are new to the series often assume that the author of the comics is a woman. Imagine their surprise when they're told that Himaruya is a male and experience their own unsettling reveal!
- This is a primary plot point in Blue Drop: Tenshitachi no Bokura. The main character must have sex on penalty of death with his best friend, who has been transformed into a girl by the evil lesbian aliens and impregnate him. Happens in the reverse, too; the friend in question is uncomfortable with having sex with the main character as well. Then it's found out that the best friend's mind was simply put over the top of a random alien girl's mind. When they fully merge at the end of the manga, it's unknown if he is a she with a guy's mind, or a guy still trapped in a girl body. It's rather messed up regardless.
- Happens to a couple of Kuwabara's schoolmates at the end of YuYu Hakusho when they mistake Kurama for Kuwabara's pretty girlfriend. In the anime he's nonchalant and even jokes a little about it, but in the manga he gets homicidally angry.
- In the second season of the anime, during their tenure in a Lady Land kingdom for the cross-dressing episode, a disguised Zelgadis meets and becomes smitten with the kingdom's demure and burdened princess, Miwan. After he saves her from a water demon named Evia, Miwan declares herself free from her burdens...and promptly takes all of her clothes off and reveals herself as a man. It turns out that all of the Royal guard was formed by guys in exactly the same situation: like Miwan, they were raised as girls by their moms to not being killed or taken away.
- A side story in the novels also has Zelgadis encounter another girl, named Miranda, dressed as a male bounty hunter. During his fight with another chimera, her gender is revealed.
- Fruits Basket:
- Most of the Zodiac, plus Tohru, get a huge shock in the manga upon learning that Akito, the head of the Sohma family is actually a girl but was Raised as the Opposite Gender.
- Tohru is also shocked to find out that Ritsu is actually a boy. She never would have known except for the fact that he transformed into a monkey when they embraced.
- Flame of Recca:
- Happens twice in the same minute in the anime. A dim bunch of henchmen have been told to apprehend a high-school-age boy, and they identify Fuko (a very tomboyish, macho girl) as their target. Immediately afterward, the rather feminine Tokiya screams at them, "You idiots! I bet you thought I was a girl!"
- Subverted in the manga. Recca asks Aoi three questions, the third being "Are you a guy or a girl?". Aoi answers that he's a guy, but instead of being stupefied about the gender, Recca merely brushes it off to mean that he can fight as he pleases.
- Asuta from Kashimashi: Girl Meets Girl, whose best friend Hazumu got turned into a girl, struggles with this a great deal. Strange enough this is only played for laughs, whereas the feelings that the female friends have for Hazumu get treated a lot more seriously.
- Sailor Moon:
- In the first anime Minako manages to nonchalantly gush over Haruka a few times well after everyone else was clued in to her being a girl.
- And the readers themselves will experience an unsettling reveal if they compare Zoisite in the original Japanese version and the American dub.
- Also, the Starlights (in the manga).
- In an early episode of the anime's R season, Mamoru and Usagi team up to take care of a baby named Manami whose mother is hospitalised after an attack from the Monster of the Week. When they change the baby's diapers, it turns out Manami is a boy and not a girl; he has a Gender-Blender Name and had been referred to with gender-neutral pronouns. (The dubs generally handle it by referring to the baby as a girl first, and then as a boy.)
- Happens in the anime Girls Bravo, where Fukuyama starts hitting on and eventually sticks his hand into the panties of a crossdressing Yukinari . His reaction is not pleasant considering the fact that he is extremely androphobic and is allergic to other men.
- .hack: Given that the entire series is based on a fictional MMORPG, there are plenty of GIRLs around.
- In .hack//SIGN, Tsukasa is the Bridget that gets dropped on herself. Among the initial worries that come with a revelation like this is that her gender will affect her relationship with Subaru. Turns out, it didn't matter.
- It also happened in .hack//Roots when two female players attacked Haseo and their voices change.
- The audience of Otome wa Boku ni Koishiteru gets the main character Mizuho's gender dropped on them — if they didn't read the series synopsis before watching the first episode. Most of them, mortified at having cheered at the fanservice, firmly invoked the First Law of Gender-Bending in their minds.
- The relatively obscure manga and animated movie They Were Eleven by Moto Hagio features an incredibly feminine recruit who is eventually revealed to be an alien who hasn't yet decided whether to be male or female, and actually became a recruit to avoid being forced to become a girl as well as a pawn in Arranged Marriage imposed by their family.
- Hayate the Combat Butler:
- Poor Hayate gets forced into female clothing often, and there have been several cases of this. However, the most amusing was when he had to crossdress in order to attend an anime convention, and ends up having to fight a giant robot while wearing a maid costume. Naturally, this makes all the fanboys happy and taking pictures, even mentioning 'I saw white!' only to have Hayate respond that he's a guy. Their response? HE'S A TRAP! and, of course, take more pictures.
- Luca, a pop star that Hayate helps after the robot hurts her, falls for it too, even going so far as to change in front of him. Due to the large amount of stress she's under, Hayate tries to keep up the disguise, digging deeper and deeper with lies. The plan finally fails when she gets into a bath that he's in, along with more than one of his female classmates.
- One butler falls in love with Hayate, who at the moment is under a crossdressing curse (...). Although initially devastated when Hayate's cover is blown, he quickly comes around and tries to convince Hayate to travel with him to the Netherlands, where same-sex marriages are legal. (Cue Nagi's Megaton Kick.)
- Ban and Ginji actually try peeping on the very girlish-looking Kazuki in a hot spring in an episode of Get Backers, mistaking him for a girl at a distance. Later, Amon Natsuki hits on him and tries to pull an I Kiss Your Hand. Juubei merrily skewers them both times.
- In Vandread, Bart Garsus gets a Bridget dropped on him with The Reveal that BC is a Gender Bender Mole. In the end, it doesn't stop him. If anything, it made it easier for him to accept his own feelings: the premise behind the whole series has men and women living on completely different planets — so same-sex "loves" were common practice.
- Jan Suk in Monster has the Bridget to end all Bridgets dropped on him when he starts confiding in a cute blonde girl he met at a bar. Not only is she actually a man, but she's Johan. Also counts for the viewers, as it's a Shocking Swerve. Johan had been impersonating his twin sister as part of a plot to make her question her sanity, and his disguise and behavior were convincing enough that even the audience doesn't suspect the truth. The eventual reveal has caused anime clubs to riot.
- Naruto: During the Land of Waves Story Arc, Naruto meets Haku, whom he takes for a girl (Not that this is hard), and Haku corrected him on this assumption right before he left.
Haku: Oh, and by the way? I'm a boy. [goes away]Naruto: No way?! He's prettier than Sakura!
- Happened to Karin in Kamichama Karin at the end of volume 4 finding out her crush, Kirika-senpai, is female through an incident of seeing (and accidentally feeling) her revealed cleavage in an unconscious state. The audience gets the Bridget dropped on them first as it's revealed in an earlier chapter.
- Shaman King has Amamiya Ryu aka Bokuto no Ryu, who thinks that Lyserg Diethel is a girl at first. When Lyserg reveals his gender, Ryu can't believe it until Lyserg either lets him check in his underwear (anime) or drops his pants in front of everyone (manga). Ryu doesn't seem to care and remains very protective and devoted to Lyserg even after Lyserg's Face–Heel Turn and defection to the X-Laws.
- Alto Saotome from Macross Frontier, a former Kabuki actor who often played female roles, gets this a lot... but trust us, he's certainly not happy about it. In one episode a salesman mistakes him for a girl and tries to sell him women's clothing, to which Alto angrily points at his Adam's apple and says "Does THIS look like a woman to you?!" Teammate Mikael loves to jerk Alto's chain by referring to him as "Princess Alto" and similar nicknames.
- Wandering Son:
- This happens to Riku Seya, a classmate of the Nitori's older sister Maho and her eventual boyfriend. Seya saw Nitori dressed as a girl and became infatuated, and convinced Maho to set them up. A future date at the aquarium turns into a rather shocking revelation which is not helped by a friend of Nitori's, "Mako-chan" (no, not that one) also revealing herself as biologically male. Seya is left rather confused by it all but they eventually become friends.
- The series has had a few instances of the rare female-to-male Transsexual case too. For example, Shiina originally mistakes his (adult) girlfriend to be cheating with Takatsuki. He grabs his groin but notices he's biologically female. After it all clears up, Takatsuki and Shiina become good friends.
- On the first day of middle school Chizuru goes to school in a gakuran and is mistaken for a boy until her best friend berates a girl for doing so. Chi often screws with the schools uniform code, be it wearing a tie instead of a ribbon or just outright crossdressing.
- It's implied that Yuki knew Takatsuki was a trans boy, but she didn't realize Nitori was a trans girl. Neither of the two knew Yuki was a trans woman. The characters get a bit surprised at the reveals.
- Rurouni Kenshin:
- Villainous Crossdresser Kamatari drops this on his opponent Misao (and everyone defending the Aoiya as well) quite dramatically, complete with pixellated naughty bits. Note that particular scene was only in the manga; in the anime he does reveal his gender too, but without flashing anything.
- Kenshin himself often causes this with viewers, and the fact that he's voiced by a woman in the original Japanese makes it worse (and legend has it that the character designer for Guilty Gear first came up with the character Baiken after making this mistake) and he's in fact based on a historical samurai, Kawakami Gensai, who used his feminine appearance to get close to his targets and even managed to assassinate a man in broad daylight. He even hid out in a brothel at one point after an assassination.
- Subverted in the adult manga Sundome; Sahana tells Hideo that she used to be a guy, but it's a trick to try to get him to stop masturbating so much. It Makes Sense in Context.
- Ouran High School Host Club:
- Happens to several characters when they discover Haruhi's real gender, most notably Tamaki, Kasanoda, and in the last chapter, the entire female customer base of the Host Club. And then Double Subverted when Haruhi tries to explain the truth of her sex to the club's customers, the girls assure her that they've known all along and don't mind a bit. Only later, after Haruhi and Tamaki have left for America, is it revealed that what they "knew all along" was that Haruhi was a gay crossdresser and that Tamaki was in love with "him."
- Surprisingly does not happen with Haruhi's Drag Queen father Ranka. The host club knows that he's her father from the moment he enters the scene.
- An oddly sexuality-inverted version occurs in Glass Fleet when Holy Emperor Vetti Sforza finally manages to get Michel Volban, the leader of La Résistance, into his clutches... and, upon drugging Michel in order to have his way with him, discovers that Michel is actually a woman. Vetti seems rather put out about it.
- Ranma ˝:
- The reverse happens to Akane at the very beginning of the series. She wasn't exactly thrilled to find out that the shy and awkward girl she had just made friends with was actually a guy.
- A subversion: Hiroshi and Daisuke's discovery that the cute redheaded girl they were hot for is actually their male best friend does absolutely nothing to stifle their crush ("Why can't there be more girls like him?")... though this is because Ranma doesn't wear bras and tends to get "her" shirt destroyed in public fairly often, as well as being willing to dress up in deliberately "sexy" clothes in order to manipulate Kunô or some other sap.
- This happens to Ranma too, when he tries to romance Tsubasa to get "her" to give up on Ukyô and his own female side. His reaction to finding out Tsubasa is a male Master of Disguise (which includes crossdressing as a girl) is not pretty.
- One little thing to note here: in his usual mood, Tsubasa even sounds like a girl. The first hint to viewers that something's off about "her" is that, whenever he gets angry, his girly impression slips and he talks in his usual deep voice. Not that anyone in the show has taken notice of that...
- Everyone believes Konatsu to be the legendary Genius Kunôichi (female ninja), and have even braced themselves for her coming out of the closet to confess undying love for Ukyô. Then a stray bomb goes off, blows apart Konatsu's outfit, and reveals "she" is a very feminine-looking "he". Ukyô is just as stunned as everyone.
- A rather bizarre example occurs in Fist of the North Star: Rei is introduced wearing a pink cloak and is mistaken for a woman, as only his eyes are visible. It's not until he speaks, and fully pulls the cloak off that his manly bod is revealed. It's worse in the anime, where Rei is pursued by several men trying to get a date.
- Omamori Himari did this recently with a side character. Right after Rinko mentioned about her having two more rivals... lampshaded by Himari.
- In Gankutsuou, this happens to Albert as early as Episode 2. The "woman" then proceeds to tease him about it for the rest of the series. And later appears to go on to a successful modeling career... This is an expansion of a minor character from The Count of Monte Cristo, who lured Albert into Vampa's trap.
- The main premise of 80s series Stop Hibari Kun. Main character Kohsaku moves in to his dead mother's yakuza friend and falls in love at first sight with the eldest and most beautiful of his four daughters... only to later find out that she is actually biologically male. Hilarity ensues.
- Classic example: Shun from Here Is Greenwood. He's used for a prank because of this, and the reveal (more rage-inducing than unsettling) comes when he's caught in front of a urinal.
- Fullmetal Alchemist: Happens to Greed in one OVA in which he flirts with "Winry" who is actually the shapeshifter Envy, who is male in this version.
- Cowboy Bebop:
- Ed! Nobody finds out she's a girl until Faye tickles her! Everyone else can be forgiven since she's a pre-pubescent Tomboy with little social skill, and it's also a Mythology Gag to when Ed really was a boy in the original version of the story before being changed to a girl for cast balance.
- A downplayed version-Gren is a male with female breasts due to being used for drug testing.
- The appropriately-titled No Bra centers around a guy who finds out that his Forgotten Childhood Friend Yuki is actually a guy, despite what he looks like◊.
- Happens once in +Anima, when a boy named Kevin falls in love with Husky, thinking he's a beautiful Mermaid Princess. Eventually, Husky tries to break the news him that he's really the 'Mermaid Princess' without overwhelming him, but ends up screaming it at Kevin before becoming human again. Kevin, is, to say the least, rather shocked that his Mermaid is Husky.
- An episode of Kodomo no Omocha has a subplot where one of Sana's friends develops a crush on an upperclassman tennis player. When she confesses her love, the object of her crush explains that she's a girl.
- Rose of Versailles:
- In the anime the Duke of Orleans tried to invoke this by having a very girlish and young-looking henchman impersonate Marie Antoinette, thus ruining the marriage to the Dauphin. It doesn't work, since Oscar manages to stop him and Marie shows up in time.
- Also tends to happen fairly often that Oscar herself is mistaken for a gorgeous man, only for Oscar or someone in the known to clear the mistake and unsettle the poor woman. Note that this did nothing to stop the creation of a rather large all-female fan club for Oscar...
- Lesbian variant: In the first OVA of El-Hazard: The Magnificent World, Makoto is forced to pose as the missing princess Fatora. Apparently, he pulls this off a little too well, because Fatora's lesbian lover Alielle climbs into bed with him. Her response basically boils down to: "Well, that's new... wait a minute... Oh, my God!" The episode ends with both of them screaming. In The Alternative World, the real Fatora tries to return the favor to Alielle, but instead finds Alielle's very similar twin brother. "It just went... squish."
- And You Thought There Are No Girls Online plays with this quite a lot. Most notably, it manages to pull this off twice with the same character: a girl Rusian is crushing on in-game reveals herself to be a man in real-life (which gives Hideki major trust issues), but it's later revealed that she actually is a woman in real-life - his high-school teacher, no less - and she'd merely been invoking the trope to stave off unwanted male attention.
- Prunus Girl: Logically, Maki "knows" that Aikawa is a guy, but he still can't help but be frequently embarrassed by Aikawa's antics (and occasionally be tempted to take up offers to personally verify gender). Meanwhile, his friend Kadoyama is hopeless over Aikawa, declaring "who cares as long as (s)he's cute!" and getting really worked up. A nameless herd of classmates seem to agree.
- Mobile Suit Gundam 00: Tieria Erde, although his voice and personality help to only keep the viewer in the dark for parts of the first episode. Still, his girly looks and the fact that he wears a fuzzy pink sweater when not burninating the countryside in his Gundam cause enough of a double-take to fit him in here. To add to the confusion, the people making the show claimed Innovators have no sex. They actually meant that they were androgynous. It was just badly translated and underwent Memetic Mutation before the correction came around. He doesn't make it any easier in the 2nd season, when it's shown that when it's needed, he can really fill out a ballgown. Maybe Eiji gave him some tips...
- In the Hideshi Hino short story Sailor Psycho, a girl is invited to the school idol's house to paint her portrait. She ends up discovering that the school idol is really a crossdressing boy with a school uniform fetish. The girl is killed when she freaks out and we find out that the idol's "mother" is really his crossdresser father and the old caretakers of their mansion are also crossdressers.
- Subverted in The Day of Revolution Former boy Megumi actually wants to drop a Bridget on the only boy at school who doesn't know her "secret" but the other girls forbid it for reasons of their own. (And when she finally did decide to tell him he wasn't listening.)
- Played with in all directions in the manga series Family Compo. The main character moves into his aunt and uncle's place and finds out they're both transgender. There are some other trans and crossdressing instances as well.
- In Bleach, Yoruichi debuts in the form of a male cat, complete with male voice actor. Her actual form is very feminine. Kisuke Urahara's first line spoken to her cat form was "Who's my favorite pussy?" in the English dub... Hilarious in Hindsight or Getting Crap Past the Radar?
- In episode three of Kino's Journey, a Bridget was dropped on all the audience members who thought Kino was a boy. The ones who guessed right didn't hesitate to pat themselves on the back.
- In Maria†Holic Kanako, the lesbian protagonist, meets the girl of her dreams in the form of the Mariya after transferring to all girls school. Later she walks in on Mariya changing and discovers his secret. She spends the rest of the series being relentlessly bullied by him into keeping his secret and suffering innumerable Stupid Sexy Flanders moments.
- Azami in Himawari!. "Wait... the hot one?"
- In the Arina Tanemura manga The Gentlemen's Alliance, the character Maora was so feminine in the first volume that even the staff who read it thought that he was a girl. His real gender wasn't revealed until the second volume.
- Pokémon Adventures:
Gold: Hi there miss. Isn't it lonely to do sightseeing by yourself? Wanna go for a cup of tea together? The name's Gold. I'm from New Bark Town.
Bugsy: I...I'm Bugsy from Azalea Town. And... well... I'm a guy.
- Another Bugsy example happened in Pokémon Golden Boys, another adaptation of Pokémon Gold and Silver. When meeting Gold, Bugsy referred to himself as "... a bug keeper boy..." which provoked a "You're a boy?" from Gold. Nothing else was noted though.
Brock: Hey, you're not changing with Ash and me? Is it because of May?
- In the anime, Brock wound up subverting this on one occasion. He knew something was wrong when a ridiculously Hot Scientist didn't make him delusional. Turned out to be a man in disguise working for Team Magma. In a later episode, he identifies the same disguised man out of two otherwise indistinguishable Jennies by the same lack of a Raging Stiffie.
- And then later he accidentally hits on Harley.
- He also failed to realize that Anabel/Reira was a Bifauxnen.
Anabel: No, it's because even if I don't look like the part... I'm a girl.
- Brock also sometimes falls for Ash whenever he dressed up as a girl.
- An example between Pokémon: Meowth and Ash's Oshawott both fall for a Purrloin. The expressions on their faces following the surprise revelation are priceless. The pairing name for this Purrloin/Meowth became, appropriately enough, Bridgetshipping.
- Happened to Blade in NEEDLESS after rescuing a crossdressing Cruz.
- When Kouji Nanjo from Zetsuai 1989 was a young boy, he once saw a rage-filled, beautiful tomboy named Izumi. He fell in love with her at first sight, but she disappeared from his life as fast as she arrived. Several years later, Kouji is watching a high school soccer game and recognizes one of the players, soccer star Takuto Izumi, as the young girl that captivated him, since "Izumi" was the kid's surname. After quite some Gayngst about it, Kouji decides that he doesn't care, he doesn't like men that way, but... it's *Izumi* , dammit. Besides, it would soon get worse.
- Himemaru in Rappi Rangai. Despite being born male, he decided to become a kunôichi because he had the "prettiest face in the village," though Kisarabi claims it was because he didn't want to put himself through the hard training to become an actual male shinobi. In either case, he seduced Raizou in his introductory chapter, and even after his secret came out he continued making passes at him every so often.
- Detective Conan:
- The entire population of Tsukugeshima in "Moonlight Sonata" case was not only surprised that the island's only doctor Narumi Asai is the Villain of the Week, but also that "she" is a man.
- Much later, Conan, Hakuba and Heiji realize that the "Detective of the South", Natsuki Koshimizu, is a Bifauxnen instead of a waifish boy. They only find out when she puts on her school uniform... a feminine seifuku instead of a male gakuran like the one Heiji has just put on. (OTOH the "Detective of the North", Junya Tokitsu, already knew and didn't tell them; in fact, he was surprised to learn that they didn't know about Natsuki's gender.)
- And the reverse-drop happens again when Action Girl Sera Masumi appears. Conan, Ran and Sonoko don't find out that the handsome and devil-may-care boy that said Ran was "his type" and helped them resolve a case, was actually a Bifauxnen... until she appears in a female highschool uniform and transfers to the girls's class.
- In manga chapter 830, it comes up again. Sera is such a Bifauxnen that even Kaitou Kid mistakes her as a boy. After having knocked her out and stripped her down to her boyish underwear and shirt to steal her clothes. Said person doesn't find out until Conan explais it to him, and when that happens a VERY upset Sera returns and kicks him to the face.
- A mild version pops up in How I Became a Pokémon Card. Akira and his best friend Akari are beginning junior high, and uniforms come into play. Akari has to wear the female uniform, which provokes Akira to mention how he didn't believe Akari really was a girl.
- In Akahori Gedou Hour Lovege episode 9, the son of a businessman that Kaoruko is babysitting (the kid, not the businessman) ends up being a girl, much to Kaoruko's dismay.
- This happens to Wataru Takatsuki in Yubisaki Milk Tea in recent chapters. However, despite Yoshinori Ikeda's initial beliefs to the contrary, Wataru actually likes him even more.
- A Running Gag with Aoi Futaba from You're Under Arrest!, a Transsexual woman whose gender issues are portrayed fairly realistically:
- Her in-canon introduction involved this trope, along with her new co-workers' reaction to the reveal.
- She invokes the trope deliberately in an episode of the anime, when she gets a marriage proposal from an Idol Singer that she's not interested in. Aoi asks for a meeting and shows up in male clothes, telling him about her issues. The guy respects Aoi's wish, withdraws the proposal, and they decide to stay friends.
- In HeartCatch Pretty Cure!, Tsubomi quickly becomes smitten with the handsome Student Council President Itsuki. When she learns that "he" is actually a handsome girl, she's upset and shocked enough to end up staying home with a fever.
- Cobraja ends up choosing Itsuki to be a Desertian (mostly) because he thinks she's a beautiful man. Then when Itsuki-as-a-Desertian swoons over a girl's uniform and reveals her actual gender, he promptly freaks.
- Also it's implied that before all these happened, Erika also had the same unsettling experience and stayed home with a fever like Tsubomi.
- Natsume Takashi from Natsume's Book of Friends tends to get mistaken for his grandmother, Reiko, by Youkai on an almost constant basis. One of these Youkai is Hinoe, who really liked Reiko and Does Not Like Men. She gets as far as groping Natsume's non-existent breasts before she learns her mistake.
Hinoe: ... Where are your boobs!?
- In chapter 279 of Air Gear while fighting Agito, Shalott reveals to Agito that he is actually a guy (and a VERY well endowed one) before knocking him down, sitting atop him and saying after he beats him up he can "have a lick" if he wants.
- In Sakura Gari, we have a boy named Youya... better known as Sakurako Saiki. This is not Played for Laughs as s/he is an insane, thoroughly broken Yandere, who ends up Driven to Suicide.
- Black Butler: While undercover in a circus, Ciel shares a tent with a skinny teen that he calls "Freckles". Turns out that he is really a girl named Doll. She offers to show him her privates so he can be sure.
- Togainu no Chi: Rin, a dude who looks like a lady, drops a bridget on Akira and Keisuke in episode 2. "Sucks to be you! I have a you-know-what!"
- MM! has Tatsukichi himself. The Crossdressing Voices helped out a lot. Taro then gets disappointed since his crush on the first episode, is his cross-dressing friend.
- Princess Jellyfish:
- In the first episode Tsukimi allows a woman who helped her to sleep in her all-female dorm. The next morning Kuranosuke is revealed to be male when he wakes up with disheveled clothes.

- The Korean Series You Are Beautiful has a convent novitiate dressing like her twin brother to join a pop band. And the drummer was the last to figure it out...
- In the episode of Quantum Leap What Price Gloria, Sam uses this trope to enact revenge on his (female) host's boss for his treatment of her best friend. Sam convinces him that his host, the woman he'd been lusting after all episode, is secretly a man, playing with this trope even though the host has always been a woman.
- In Cory in the House, it happens to Newt Livingstone when Cory poses as his sister Raven (for reasons too convoluted to get into here) and Newt falls for him despite "her" clearly being his best friend in a dress and a wig. Then again, Wig, Dress, Accent was a staple of CITH's parent show That's So Raven, and Newt is very stupid.
- Another sexuality-inverted instance occurs in an episode of 3rd Rock from the Sun, in which a Guy Of The Week dumps Sally when he finds out, to his dismay, that she isn't a guy in drag.
- NCIS has a first-season episode "Dead Man Talking". While investigating a missing embezzler, Tony ends up on a date with a woman connected to the missing man. Then learns that she is actually the missing embezzler. Afterward, Kate rarely missed an opportunity to remind Tony of the incident.
- JAG: In "Retrial", a sailor had unbeknownst to him hired a transsexual prostitute. When finding out, the sailor changed his mind and the prostitute threatens him with a knife. The sailor defends himself and accidently stabs the prostitute and runs away in fear and shame.
- Happened once to Sanchez from The Closer. He made the mistake of hitting on (and kissing) a pretty female witness...who turned out to be the perp in drag. In a somewhat darkly humorous twist, this was the incident that convinced him to start actually going to the mandatory therapy sessions with the department shrink. (Mandatory due to the fact that he was still suffering from PTSD after taking the bullet in the previous season finale; up until this incident, he'd been in denial about it.) Poor, poor Sanchez.
- Farscape episode "The Flax" D'Argo discovers that the scavenger Staanz, who appears to be a rather ugly male, turns out to be, in fact, a female of her species, and is "considered quite the looker". This becomes Squick material for D'Argo when Staanz announces her attraction to him. Briefly lampshaded at the end when a shaken Crichton asks Aeryn if she's actually a woman (which she is).
- Parodied(?) in an episode of Celebrity Juice. Host Keith Lemon, in the episode following "Let's Dance for Comic Relief", in which he was a competitor with dancing partner Paddy Mc Guinness, opened the show saying that said partner got off with 'Roberta' Webb- only to discover 'she' had a 'tallywhacker'. 'Roberta' being Robert "Mitchell and" Webb, another competitor who performed "Flashdance" in a leotard and frizzy wig.
- Inverted in an episode of The Drew Carey Show where Mr. Wick is challenged to find a crossdresser on the floor, after looking for a while Dionne Warwick walks in and Wick declares her a drag queen and grabs the music legend in her crotch. It turns out that it was the real Dionne Warwick much to Wick's embarrassment but she seemed to like being groped by him and remarked about how friendly the stores staff was.
- Doctor Who:
- The Doctor actually manages to do this to himself after his regeneration into Matt Smith.
- At the end of the 1999 Comic Relief Affectionate Parody Doctor Who and The Curse of Fatal Death, the Doctor regenerates into Joanna Lumley. His companion and fiancée Emma is disappointed as with him being "Not the man I fell in love with".... the Master, on the other hand....
- In the "Who Can Bone More Women?" Contest on Kenny vs. Spenny, Kenny hires a pre-op transsexual to get all buddy-buddy with Spenny. Spenny racks up points like crazy until The Big Reveal at the end. He is not happy.
- One episode of 1000 Ways to Die featured a rapist targeting a lady as she left a gym. As it so happens, the "lady" was a cross-dressing semi-pro boxer, who killed the rapist with one punch.
- Inverted on Reno 911!: Dangle once had sex with a woman he mistook for a man in drag.
- Done for revenge in Rab C. Nesbitt when Mary Nesbitt's sexually abusive boss is tricked into groping David Tennant.
- CSI has had at least two murders traced to violent reactions to this trope.
- CSI: NY had one as well.
- Chicago Hope did it in the middle of its run when one of the doctors, a very manly hockey player, starts dating Mia Sara. When she informs that she has something to tell him, he says that he already knows... that she has fake boobs and he's fine with it, she informs him that she actually used to be his best friend and hockey teammate in high school.
- There's Something About Miriam features a sexy lady called Miriam and a group of stud males trying to woo her attention. Except that Miriam is actually a pre-op transsexual - something the participants had no idea of but which the audience knew right from the start of episode one. The whole thing led to some of the competing men suing the TV network. And as one can imagine, transgender advocates were not thrilled at the show setting the movement back to the stone age.
- Similarly(ish): post-op Transsexual Nadia Almeida, who won the fifth series of Big Brother UK didn't tell her housemates of her... "situation". Said Bridget was Dropped upon evicted housemates in her post-eviction interview, until LGBT right campaigners complained about five weeks into the game.
- Arrested Development: Shows up in more than one context:
- Invoked and subverted by Maeby, who wants Steve Holt to think Lindsay is her father, not her mother. She goes so far as to buy her mother a shirt with a label "in French":
Maeby: "It's pronounced 'Shemalé'."
- Barry Zuckerkorn apparently seeks out this trope, exclusively:
Barry: Hey, youre not one of those silly men that’s dressed like a woman, are you?Prostitute: No, baby, I’m the real thing. (Barry floors it and drives away.)
- Invoked and subverted by Maeby, who wants Steve Holt to think Lindsay is her father, not her mother. She goes so far as to buy her mother a shirt with a label "in French":
- One episode of Law & Order: SVU involves a pre-op transsexual who appears female in every conceivable way except actual plumbing, who apparently killed a friend of her boyfriend's to prevent a public revelation. When the SVU team confront the boyfriend (ignorant of the fact that the boyfriend had no idea his girlfriend was biologically male), he runs in, grabs her by the groin to determine sex, and then runs out to commit suicide with an overdose of heart condition pills.
A judge then decides to send the extremely convincing transsexual to a men's prison because of her plumbing. She is promptly gang-raped and beaten. We are shown the aftermath, with her headed to a hospital, strapped to a gurney, basically a solid swollen bruise.
- In an episode of Dark Angel, politically and socially conservative Normal discovers that his love interest is a trans woman. Unusually, he remains interested, but is dumped after she realizes she's a lesbian.
- The subplot of an episode revolved around the team trying to figure out whether a Japanese assistant is a man or a woman. It is debated at some length before Angela figures it out in her own way. The character is a man...the actress is a woman.
- Another episode has the team realize that the victim was a post-op male-to-female transsexual. This had absolutely nothing to do with the murder.
- An episode of Diagnosis: Murder plays this straight (as it were). The victim was an MTF post-op TS, and Steve had been flirting with her before she was killed. To the show's credit, the victim was portrayed as a sympathetic character and none of the main characters freaked out about it. In fact, she was killed by her former military buddy because he was squicked, and the murderer is portrayed as a Jerk Ass.
- Will and Grace: Jack freaks out when he gets turned on by the stripper at Leo's bachelor party, until he finds out the stripper is a pre-op who dances to raise money for her operation.
- Two and a Half Men:
Charlie:... and this will be the name of my biography Me and my mom had sex with the same man.
- Charlie Sheen meets an old flame who has had a sex change and become Chris O'Donnell. He is freaked out by it but eventually comes to terms with the idea until his mother starts dating his ex.
Charlie: How was I supposed to know?"Alan: She had an Adam's apple the size of my fist and could palm a basketball.
- A Running Gag is a certain Noodle Incident where he hit on a woman who later turned out to be a man. And from such statements it was pretty obvious but Charlie was too drunk to notice at the time.
- A one-episode B-plot in Century City followed a lawsuit a man filed against a female-looking Hermaphrodite for causing him to question his sexuality. The case was dropped when he turned out to be a transsexual too, but an in-universe ad for penis attachment surgery led to the observation that "someone should sue somebody for something."
- Matt starts a relationship with an older woman named Ava (played by Famke Janssen), much to the displeasure of his three parents. Christian seduces her in an effort to get her to stay away from Matt and immediately deduces she used to be a man (and later describes her as "the goddamned Hope Diamond of transsexuals").
- After Matt finds out about Ava and she has disappeared, he trolls bars until he finds an obvious transsexual, but as they start making out, Matt discovers she is pre-op and beats her violently.
- Happens to Herb Tarlek on WKRP in Cincinnati twice (sort of):
- In one episode, Herb starts flirting with a woman who claims she knew him in high school. While making out with her, he learns he did know her in high school... before she had the operation. She was a teammate of his on the high school football team, in fact the center to Herb's quarterback. To say Herb had a case of the Squick is putting it midly.
- In an earlier episode, the trope is invoked and subverted by Johnny. To get Herb to stop hitting on Jennifer, he tells Herb "Our receptionist, the beautiful Jennifer Marlowe, is a result of the most cunningly successful sex change operation in the United States!" The ploy works... sort of.
- Double Subversion in The IT Crowd when, in a B-plot, Douglas embarks on a successful relationship with a post-op transsexual woman who insists on coming clean on their first date — but it comes crashing down when he reveals that he wasn't really listening and thought she was saying that she was from Iran, not "I used to be a man."
- Community: Pierce has to be corrected as to the gender of the singer that made Hawthorne Wipes a gay icon. The same singer is seen later on, arm in arm with Chang, leading to this beautifully ironic line:
Chang: Winger, no date? Huh. Gaaaaayyyy.
- In one episode of House, a beautiful teenage model appears to be female, but turns out to have Complete Androgen Insensitivity, with her symptoms being caused by a tumor on one of her undeveloped testicles. She is horrified to discover this, as is her manager/father, with whom she had been having sex. House's response to the manager's horror is priceless:
House: Oh, sure. Now it's creepy.
- An attempt to use this trope using a real-life trans person caused some controversy among the LGBT community in an episode of reality show Cake Boss, where Buddy invites Carmen Carrera (best known for being on Rupauls Drag Race) and sets her up on a date with "cousin Anthony", the punchline being the reveal to Anthony that his date was "really" a man, with his shocked reaction Played for Laughs. Though usually thought of as a Drag Queen, since she was one before she started transitioning, Carmen is actually a transwoman and was not amused when made aware of the nature of her appearance on the show, citing the fact that this has led to real life murders of trans people. Buddy later apologized for the incident and the episode was removed from rotation.
- On Friends, Ross reminisces about how he and Chandler once tried to pick up women in a bar. Apparently, he was unsuccessful, while Chandler ended up making out with his conquest. Monica comments that such behavior for Chandler would be highly unusual. Ross agrees that Chandler isn't the type to go to bars and make out with girls...
- Casualty once featured two patients from a car crash: a girl and her strangely high-pitched voiced boyfriend. The doctors realised the boyfriend needed a chest examination. This revealed what certainly wasn't a boy's chest.
- In Miranda, a chap complimenting large-boned Miranda on her dolled-up appearance ("You look amazing. You totally pass!") is thoroughly embarrassed to discover that she really is a woman, and is unwittingly dressed as a transvestite.
- One Title Sequence of Three's Company shows Larry getting into the same bumper car at an amusement park with who looks like a long-haired woman from the back. Then the bumper car turns around and the viewers (and Larry) discover that this "woman" has a mustache.
- A semi-common event on The Jerry Springer Show is a trans woman or man coming out as trans to their boyfriend/girlfriend/spouse. The person being told rarely reacts well, oftentimes because they're angry that they weren't informed sooner, feeling like their partner was lying to them or deliberately hiding information. Given this it's unsurprising that most of these events end with the spouse breaking things off with the transperson, sometimes due to Incompatible Orientation, other times due to no longer feeling like they can trust their partner if they were willing to hide something so major.
- The first episode of the second series of Blackadder inverts this trope. The episode opens with a beautiful but poor young woman named Kate deciding to disguise herself as a boy to find work and support her ailing father. She finds a job as Edmund's manservant, and the two fall in love over the course of the episode while he tries desperately to cognitively reframe the feelings he's having for another man. The relief he feels when she reveals her true gender is immense.
Blackadder: Then come, kiss me, Kate!
- Played for Drama with Blair and Drew on Dead Of Summer. Blair, who is gay and suspects that Drew is too, tries to strike up a relationship with him, telling him about the importance of being yourself. When he finds out that Drew is also transsexual, however, he wants nothing to do with him and is squicked out at the fact that he had kissed a boy who was biologically female.
- Why a lot of straight young Western male Youtube commenters dislike Visual Kei. Sometimes exploited by Visual Kei fans who post pics of extremely feminine Visual Kei artists to troll homophobes or transphobes either alone or with commentary that they are more "real men" than the hatemongers ever will be, and a few times actually subverted by commenters who own up to their attraction rather than explode in homophobic/transphobic rage.
- The music video for the song "Smack My Bitch Up" by The Prodigy does this to the viewer. It's a first person-camera accounting of a night of drunken carousing, drug use, and barhopping in which the protagonist gets into at least one fight with some guy, and molests a girl in a club, ultimately ending the night with a hooker. It's then revealed by a look in the mirror that the protagonist is actually a hot chick herself.
- "Well I'm not the world's most masculine man / But I know what I am / And I'm glad I'm a man / And so is Lola"
- The second version of "Uneasy Rider", when the singer and his friend go into a gay bar and the friend goes off dancing with a lovely lady.
I grabbed her hair
Came off in my hand
And that beautiful girl
Was just a beautiful man.
- The Filipino song "Chiksilog" note by Kamikazee is about a Ragnarok Online player's reaction to finding out the hard way that the "girl" his character hangs out with a lot turns out to be a Cross Player.
- The Doug Anthony All Stars song Sailor's Arms also has this theme.
- Pet Shop Boys' "One thing leads to another". The protagonist gets drunk, picks up a woman in a bar, attempts to make love to her, and discovers she's has a penis. He drives off, confused, and crashes his car and dies.
- The lead singer/guitarist of The Silversun Pickups has a very high register, causing a mild version of this for someone who hasn't seen them perform before.
- One of Aerosmith's '80s comeback singles was "Dude Looks Like A Lady," with a line that goes, "Love put me wise/To her love in disguise/She had the body of a Venus/Lord, imagine my surprise!"
- Happened near the end of "Nobody Move" by Eazy-E
- Ritsu Namine is a boy
- This review of Placebo's Once More With Feeling.
- Biz Markie's "A Thing Named Kim": "She didn't look none like she looked across the room/She had big broad shoulders and her titties was big/They were filled with silicone, and her hair was a wig... So I hurried out and left, she said, "Please stay"/I said, "Sorry money grip, I don't go that way"/So I stepped out in a hurry, to gather my wits/And thought that's a damn shame, he had nice tits/And that's the last I ever saw of Kim/You wanna know why? Cause she's a he and her's a him." Needless to say, Markie didn't win many GLAAD awards for that one.
- In a rare example that has nothing to do with appearance, most people are surprised to learn that Angela Gossow, the vocalist of Swedish band Arch Enemy, is a woman. Why? Well... just listen.
- Most J-Pop stars utilize this trope as a way to gain fans. Notable examples include Miyavi and Gackt (though Gackt is quite competent at expressing his masculinity when need be). The latter was also a major inspiration for many of Tetsuya Nomura's character designs. The Crisis Core character, Genesis Rhapsodos was directly modeled after him.
- L33tStr33t Boys song: "Lady and the Trap".
- "Luisa" by the Peruvian band Chabelos. It's about a guy who falls in love with a hooker called Luisa, and then discovers that "Luisa" is a transvestite, and he thinks that's hot.
- In Wilfrido Vargas's "Macho Man", a guy falls for a pretty girl that he later finds out, while they are almost intimate, is a pretty boy; he freaks out and runs away, losing his shoes in the process.
- In Rodney Carrington's appropriately named "I Think I'm Dancing with a Man" the singer begins to get suspicious of the woman he's been dancing with because of many masculine traits. His friend then takes "her" for a dance and "her" skirt falls off confirming it.
- Tone Loc's "Funky Cold Medina": "But when she got undressed it was a big ol' mess... Sheena was a MAN!"
- EPMD's "Jane 3" off of Business As Usual: It all starts when Erick & Parrish befriend a hard gangsta named Jay... but when they visit "his" pad, the decor (and bathroom contents) don't seem right...
- Schoolly D's "Saturday Night": "What I thought was a girl was nothin' but a fag" (Needless to say he's not gonna win any GLAAD awards either)
- From Eminem's Just Lose It:
Eminem: Now what's your name, girl? What's your sign?"Girl": Man, you must be up out your mind. *is actually Dr. Dre*
- The Eberron setting of Dungeons & Dragons actually notes that this possibility of this occuring is one of the main reasons for the Fantastic Racism leveled against the shapeshifting Changeling race, whose members are fully capable of changing not just appearance but gender at will, regardless of the gender of their actual native form. It's a well known joke in Eberron fan circles to point to any depiction of an attractive male or female character and declare that it's really a changeling of the opposite gender.
- Nevermind that picture from the Sharn sourcebook that showed a couple of the working girls in the red-light district. The jokes that picture alone spawned...
- While technically androgynous in the new fluff, Daemonettes from Warhammer 40,000 will play this trope on one of their victims just to watch them squirm. Because, you know, that's what they do. (And then they gut their victims like pigs with their claws, which can go through Powered Armor like a knife through butter.)
- The play (and subsequent film) M. Butterfly is about a French diplomat who has an affair with a Chinese opera singer, unaware that she is a) a spy for the Chinese government and b) a man in disguise. This is, believe it or not, a case of Truth in Television: the play is partially based on the life of Bernard Boursicot.
"There are no women in the Chinese Opera."
- This one's Older Than Steam because Shakespeare did it first. Someone falls for the Sweet Polly Oliver in both Twelfth Night and As You Like It.
- Bridget, the Wholesome Crossdresser teenage boy in a nun habit from the Guilty Gear series, and former Trope Namer. In Bridget's birth town there was a superstition that if twins of the same gender are born, disaster will come. Rather than let the town sentence him to death, baby Bridget's parents put him into the custody of the local convent's nun who raised him as a girl. Bridget's gender is never a secret in the game, at least not to the audience, and is spelled out right at the beginning of his storyline. He also never intentionally hides that fact anymore (it's a long story), thus only a few characters actually get the unsettling reveal. The problem is that most other characters simply assume he's a girl, either because he's lived most of his childhood as one or because of his Moe nun outfit.
- Even Zappa from Guilty Gear XX has a Bridget dropped on him in Story Mode. As written in a letter to his mom (which he writes during his brief periods of lucidity), he says he found an injured young girl by the side of the road who he wished to make his wife. (He is unaware that he is the one who pounded her into the pavement). But when he attempted to pick her up and carry her, he finds...
- At least he isn't in Johnny's shoes. That poor goon has a story mode ending about finding out too late that Bridget is a guy. ("I can't believe I hit on another man!")
- Not to mention a little Yon Koma about Axl trying to hit on Bridget. Bridget gets fed up, grabs his arm and pulls it below the panel, with the word "TOUCH♡". The final panel has Axl gripping said hand with a horrified expression, going "What the hell did I just touch?". And "DESTROYED" in large letters above him, referencing the One-Hit Kill attacks from the games.
- Speaking of BlazBlue, if you pit Bang Shishigami against Noel Vermillion in Continuum Shift, he mistakes her for "a young man" despite her rather girlish clothing including a Dangerously Short Skirt. Noel will believe it's because of her lack of boobage and GET PISSED OFF.
- Amane Nishiki makes that mistake in Arcade Mode, too. He comments how Noel would be perfect playing the roles of women (never mind Noel is a girl) with the kind of crossdressing she's wearing at the time.
- Also speaking of BlazBlue, Kagura Mutsuki has a match intro where he scans the female anatomy, complete with targeting reticules and readouts. He does this with Amane Nishiki as well, and expresses disappointment at the obvious. For Fridge Brilliance, Kagura's exact quote is "Not another dude...", which means he's already experienced this trope a lot and Amane wasn't his first case.
- Over here in Real Life, people have found it quite amusing to show Bridget to those who aren't familiar with the Guilty Gear series, and get their reactions when they drop the bombshell, as it were (s/he and other characters of this trope are called "traps" for this reason). As the meme says, "Everyone is gay for Bridget".
- Leisure Suit Larry has this happen in both the sixth game ("Shape Up or Slip Out!") and the eighth game ("Magna Cum Laude"). The former involves a plot-critical sexual encounter with a very well-endowed transsexual/transvestite named Shablee, whilst in the latter, an optional character to pursue, Koko the shy mime, is actually a crossdressing boy.
- And for the most famous female example, you have Sheik of The Legend of Zelda: Ocarina of Time. Earlier in the game, Ruto called "him" a man. She was wrong. You know that you have an epic gender reveal when the fandom spends ten years starting Flame Wars over it.
- This happens to Tink in Disgaea 2 when he tries to hit on a Cute Monster Girl after joining your group. Of course, nobody bothered to tell him that the aforementioned "girl" is, in fact, Bridget's Lawyer-Friendly Cameo...
- Also happens in Prinny: Can I Really Be the Hero?. The cute little Incubus is revealed in the hidden Monsterpedia section that "she's" a he.
- The Alraune trap is brought back again in Disgaea 4 when the Cute Monster Girl in question is revealed as a guy in front of "her" adoring fans. Said fans decide that they "don't mind a little trap action."
- In Dragon Age: Origins, it turns out that Shale was actually once a female dwarf. Thanks to The Fog of Ages, even the character in question is stunned by this, making it a rare case of the character in question experiencing the unsettling reveal.
- In Metal Gear Solid 2: Sons of Liberty, Raiden, a shameless Bishōnen, is revealed to the President of the United States. The president literally grabs Raiden's package to check his sex, reacting in suppressed shock when he learns the terrible truth — the script says he'd misidentified him as the similar-looking female terrorist leader, Olga Gurlukovich, but Raiden's decidedly male voice and obvious bulge should have put that suspicion out the window. Besides, why didn't he just ask Raiden?... What was he planning to do to Olga?! Who voted for that?!
- Fire Emblem:
- Fire Emblem Elibe:
- In Fire Emblem 7, Serra is rather cold to Lucius when she thinks he's a girl in their C support, but when she finds out he's a guy, their B support has her going all starry-eyed.
- Fire Emblem Awakening:
- Averted with Lucius's expy Libra. He mentions after being called a sister by Chrom that he's actually a priest. When he apologizes, he mentions that it could have been awkward. Very awkward. Very Very awkward. Unsurprisingly, Chrom tells him to stop. ("God give me strength. Even the Queen's brother confused me for a woman.")
- Things indeed become funny and awkward in Libra's supports with Virion, who continues to flatter his beauty even after finding out he's a man.
- And he's also mistaken as a woman by at least one potential girlfriend/wife. See his C support with Sully... who, ironically, is one of the tomboys of the cast.
- And in Libra's solo ending, it's explicitly said that he both built an Orphanage of Love and was asked out by both guys and girls.
- It might be a trap for players to trap players who are expecting a "trap", but there is a masked young man who claims to be Marth and backs it up by wielding Marth's legendary sword, the Falchion. People are already very aware of Marth's gender at this point, right...? Turns out, this "Marth" is an imposter... and a girl. Yeah. Marth is A Girl, and a very beautiful one too.) (You may now squee). In fact, according to the promotional manga, in-story this took place sooner than we thought... Remember that Lon'qu was defeated by "Marth"? One of the reasons is that, during their fight, Lon'qu accidentally bumped head-first into Marth's chest and realised that his opponent was a woman. Since Lon'qu has a bad case of gynophobia due to his Dark and Troubled Past, well...
- Fire Emblem Elibe:
- Flea from Chrono Trigger has confused generations of gamers with his/her claim that he/she is actually a guy, despite having obvious cleavage in the artwork. Not to mention the actual heroes, of course. Luckily Flea plays no role whatsoever in the story other than to be a Mini-Boss. It's possible that Flea could, however, be FTM or the result of a magical experiment that stuck him in a female body/gave him breasts.
- Final Fantasy IV has a certain dancer in the town of Fabul.
- Final Fantasy V. The leader of a band of pirates called Faris is assumed to be a male due to occupation, but once the party gets halfway through the second dungeon it turns out he is a she. To quote a boss later on in the game, And now we shall fight like men. And women. And women who dress like men. She even occasionally mistaken refers to herself as male. It's clearer in the original Japanese, where gender is reinforced by speech much more than in English. (For example, Japanese has gender-specific first-person pronouns, not that this stops some people.)
- Final Fantasy VII: It's possible to get the Don to choose Cloud, in which case he reveals that he was in drag. While the idea of the Don picking Cloud over Tifa and Aerith may seem silly and unlikely based on the graphics in the original game (and their low polygon count), the Don's decision becomes much more understandable if one looks at Cloud's character design in Advent Children, especially if Cloud-in-drag appeared anything like THIS◊. Stupid Sexy Cloud.
- The Digimon series has played with Renamon's gender (or lack thereof) for some time, but Digimon World Data Squad amped it up by giving us a male Renamon with a painfully obvious female voice (in fact, it was the same voice actress who played Renamon in Tamers). Let's ignore the Unfortunate Implications of a male Sakuyamon. The German fans must've been laughing hard at that one.
- Iita in Blaze Union. Oh, ye gods, Iita. She's a perfectly adorable little Fille Fatale, cute and squeaky and very girly. Then night falls, and the other half of her Split Personality takes over — the side that is male, brash, Hot-Blooded, and downright thuggish. Her male half cheerfully announces to the stunned women of the game's cast that "oh right, sorry, I forgot to say: I'm a man at night". Equally shocking to people who first see Male!Iita and then realize that what they thought was a boy dressed in girl's clothes is actually still physically female.
- Sting is all too happy to play with the latter situation, by the way; as is the norm, a number of Fanservice-y phone cards are being produced. One features Male!Iita smirking and slowly peeling the clothes off of his very female body.
- While the title heroine of Atelier Annie has her moments due to her (unfortunate) Bifauxnen status, the game also gives a somewhat bizarre example when some men tried to hit on, of all people, Hans. The bizarre part is that they genuinely mistook him as a girl, while his co-workers in the Committee see him as a guy just fine.
- Unsurprisingly, the Camwhore class in Forum Warz has this as a standard attack, if one not often seen. (It's down the line of a skill chain which many players respec out of before obtaining it.) Note that the gender, age and race of every player character is defined as "whatever happens to be squickiest at this instant". The same applies to any NPCs who use multiple or artificial personas, eliminating any potential shock value out of gender. (Especially as very few players would be attracted to most of the NPCs.)
- Erica from Catherine is actually a post op transsexual. However, Vincent, Orlando and Jonny are aware of it, and there are several hints dropped over the course of the game before the actual reveal. It's only this trope to Toby, who lost his virginity to her.
- Dark Souls has the Dark Sun Gwyndolin, the last born son of the Lord of Sunlight, Gwyn. Because of his lunar magic and association with the moon, he was raised as a girl. He even has tits.
- One of the Ferris Wheel date options for the male player character in the Japanese version of Pokémon Black 2 and White 2 is a schoolteacher who, mid-ride, takes off his shirt in the heat and admits he had to pose as a woman to get the job. This is censored in most translations.
- Gothorita mentions in PokePark 2: Wonders Beyond that many Pokemon mistake him for a girl.
- In Persona 4, exactly how Unsettling Naoto's Gender Reveal is to Kanji is a vital piece of the latter's characterization. Kanji, who can be interpreted as struggling with very deep sexual identity issues, textually expresses almost the exact same mixture of anxiety and eagerness in interactions with Naoto before and after the scene in question. Perhaps most tellingly, though, Kanji is at his most resolute when Naoto's life is in imminent danger of Shadow-fueled destruction, only moments after the Reveal itself.
- Persona 3 has the more basic Played for Laughs version of the trope during "Operation Babe Hunt."
- The thief in Ratchet & Clank: Going Commando is revealed to be a girl, upon which Ratchet comments "Whoah! He's... a she!"
- The Japanese Animal Crossing has this according to Blanca's bio. It translates to: "When I suddenly met her she asked me to please paint her face, it really surprised me! Did her makeup fall off maybe? Huh? She’s a boy?!"
- NieR has an unusual version of this in that one of the main characters, Kainé, is revealed to be a hermaphrodite. This is done very subtly in-game, so a lot of people might have ended up not realizing it if that piece of information hadn't been leaked somehow before the game even came out.
- Elh from Solatorobo talks and acts like a boy, but is revealed to be a girl when Red walks in on her bath.
- In Dangan Ronpa, this trope happens with Chihiro. Since this happens after he is murdered, it becomes even more unsettling.
- In Fate/stay night, there's a reason why Guinevere had that affair with Lancelot, since her husband, King Arthur, aka Saber, turns out to be a woman (and stopped aging at the age of 15), but Guinevere agreed to the marriage as political fiction only, and due to that reason Arthuria never blamed Guinevere nor Lancelot for their romance and was forced to take action against it by her enemies.
- This also occurs in the prequel series Fate/Zero, where Kiritsugu is quite shocked when he summons King Arthur and finds himself face to face with a young woman. While Saber initially thinks that it's because he's displeased by her sex, Kiritsugu's wife Irisviel explains to her that it's more than he's saddened because he realizes what Saber was forced to go through, including hiding her identity.
- Shika in Kira-Kira, when a guy fell in love with him when he was forced to cross dress. Two years later, he was shocked to realize that Shika was in fact male, but quickly got over it even offering to be his wife since the idea seemed to make him uncomfortable.
- Robin Newman in Phoenix Wright: Ace Attorney – Dual Destinies. It catches EVERYONE in court off guard, including Blackquill.
- Invoked and parodied by the narration when Ruka is introduced. Without prior knowledge of the character, you will assume they're a girl (the Miko outfit doesn't help), but Rintaro will eventually start making complementary remarks in narration "More feminine than any woman alive..." only to end them with "...But, he's a guy!".
- Kurisu also appears quite disturbed the first time Rintaro corrects her when she talks about how nice Mayuri's 'female' friend was.
- In-universe example for Rintaro after Ruka manages to change her sex to female (at birth) using D-Mail. The fact that she looks exactly the same either way doesn't help matters. Arguably, it's just as unsettling for Ruka herself, as Rintaro tries to grab 'his' area to prove 'his' gender.
- Much later, Ruka receives one of these for herself, when she comes to remember parts of another world line where she was a he.
- This joke was done as a gag during a scene where Hal is trying hit on women in episode 6 of Bowser's Kingdom.
- A Running Gag in Gamer Poop which takes place at LEAST once an episode.
- Parodied (along with many other anime tropes) here.
- Unsettling in-universe for Carl from Llamas with Hats to learn that his roommate, who had been unidentified prior to that point, was a male named Paul (in Carl's defense, Paul's hat is rather feminine, but he couldn't even remember Paul's name after three years). After asking Paul if he's sure, which Paul confirms to his annoyance, Carl then says he has to go delete some pictures from his computer.
- In El Goonish Shive, this happens quite a lot when someone's stepped out of their normal gender. Somewhat unusually, it often gets milked for some drama in the process.
- Justin and Susan almost do something they'd regret later while both gender-bent for Grace's birthday party. Good thing they didn't, since Justin likes guys; things would have gotten awkward once Susan became a woman again.
- The "Sister" arc was full of this. Minor characters were falling at Elliot's feet, and that's before Ellen took on a life of her own.
- The Wotch manages to do this to both participants, here when Jason is transformed into Satyr Sonja he has random flirty outbursts he can't control. When he "puts the moves" on Robin they both freak out. Jason continues to flirt-and-freak throughout the arc. And one flirt-and-freak recipient winds up wanting to date "Sonja" later.
- Chapter 66 in Welcome To The Convenience Store.
- Ghastly's Ghastly Comic:
- A rather ridiculous case when the two similar-looking characters in the rather ambiguous fighting game (within a webcomic) "Loli vs. Shota", both finally decide to actually check their genders... and are shocked to find out that they're both wrong on which one they thought they were. And yet even though we learn they're both wrong, the reader still is left in the dark about which character is which gender.
- A Running Gag is that masculine characters tend to have sex with Freddy... who, despite having breasts, is male and revels in it. They tend to be very drunk at the time.
- The Order of the Stick :
- Averted very carefully by Vaarsuvius, an elf whose gender remains unspecified (and just to keep the readers guessing, the gender of V's lawfully wedded spouse is also unspecified and their kids are adopted.)
- Invoked when Belkar hits on a magically gender-swapped Roy. Turns out, he knew it was Roy the whole time, and he was just doing it to squick him out.
- Concession: Artie wakes up to discover he has engaged in inappropriate acts with hypersexual preteen Chelsie Warner while in a brain-tumour-induced — or, as it turned out, Joel-induced — trance, and confides in his boss:
Artie: But honestly, I'm not sure what disturbs me more... the fact that this happened, or the fact that Chelsie is actually a boy.
- This later happens during an occasion where Joel, Matt, and Aaron "Nicole" O'Connor meet with a crude ursine associate of Matt's who initially believes Nicole is a girl after Joel introduces them. Needless to say, said ursine friend is moving to kick Joel's ass when he finds out the truth of Nicole's gender.
- This strip of Something*Positive.
- In this strip of Sluggy Freelance, Riff and Torg run into First Officer Brenas, a shapely woman who is actually the male of the species. Riff and Torg subvert the trope by not being bothered at all.
Torg: Aw, you think what you want.
Riff: Can you jump up and down for us, mister?
- Dan and Mab's Furry Adventures :
- Dan infiltrates Twink Territories dressed as a woman. Later on, Biggs finds out. Quoth Biggs: "I'd probably feel more awkward if this was the first time this had happened..."
- In another story arc, the shapeshifting incubus Abel takes a job working at the Lost Lake Inn. Dan gripes that it'll be an unfortunate adventurer who comes into an inn hoping for the traditional greeting and service by a perky cute beer wench. Abel: "Oh, well if THAT's your only issue..." Dan * turns around to see Abel has put on a very convincing female form* "YIGG!" Page caption: "Don't worry, adventurers are used to dealing with traps."
- Later on Dan meets Mink, who is androgynously pretty, flat-chested, and runs around in a skirt and no shirt. Dan outright asks Mink whether they are a boy or a girl, only to find that Mink has forgotten hirself (being another shapeshifting 'cubi). Mink is on the point of taking a peak down hir skirt to refresh hir memory when Dan decides that he doesn't really need to know that badly.
- Venus Envy has this happen to Lisa when she assumes that Chris is a male-to-female transsexual only to discover that he's actually just a Wholesome Crossdresser. Chris gets experiences this trope when he first meets Lisa and Zoe, assumes they're crossdressing boys as well, and grabs Lisa's breast while telling her it "looks totally fake". They beat him up.
- Material Girl, in which the character the title refers to isn't really a girl.
- This page, from DOUBLE K.
- Used in MegaTokyo early on, when Piro is reading through a section of girl's manga in a shop in Japan. A Japanese schoolgirl seems to think that Piro is a girl and is "cute". Her friend informs her that Piro is, in fact, a guy.
- A double inversion of this trope occurs in Teh Gladiators, first when the Murlocs that join the heroes turn out to actually be female, and then when one of them, Yolanda, develops a crush on Vallant rather than vice versa.
- Done in this strip of Head Trip.
- Jet Dream:
- Averted by the Elle-Boys of J.E.T. T.E.E.N. Despite looking exactly like girls, they make no secret of the fact that they're actually boys. As a rule, they're also heterosexuals who exhibit many "traditionally masculine" traits.
- In the story "South Pacific Powder-Puff Power!"note , there's a startling revelation about a longstanding character. The T-Girls learned that Ting, the Polynesian princess and only "female" member of the Thunderbirds, had actually always been a male. In Ting's matriarchal tribe, male royals are expected to live as women. When the rest of the team changed sex, so did Ting.
- Reversed in Kevin & Kell. Rachel, upon first meeting Bruno, tries to romance him because she thought he was a sheep. To be more specific, not a male sheep. You see, Rachel's a rhino with bad eyesight, and had gone by the smell of the sheepskin Bruno was wearing, which was made from his girlfriend Corrie's wool. The end result was Bruno added ram horns to the sheepskin so he's never mistaken for a girl again.
- Done in this strip of Dueling Analogs, where one man mistakes a Bridget cosplayer for Rosette Christopher.
- Alucard pulls this off as Girlycard in And Shine Heaven Now. Granted, the person he fooled is Bertie Wooster... And then many years later did it to Maggie Mui...
- From Reversed, after a long overdue reveal: "What is this, Effin Trapsville?"
- Happens to Pintsize in Questionable Content when he learns that the AnthroPC with whom he's been chatting is actually a male AnthroPC whose online icon happens to be pink.
- Doubled up in the now defunct comic Roomies with Corey and Dave(ina), they were both posing as men so their boss and co-workers in IT would take them seriously when they went on a date and revealed to one another that they were actually women. They started sleeping together anyways.
- Sexy Losers loves playing with this trope. Most notable is one comic in which a man picks up a woman with short hair at a bar, only to take her home and discover she is a woman, but he's gay and he thought he was hitting on a man to begin with.
- Would that be a booby trap?
- Another Sexy Losers strip has one guy get a pregnancy scare from his girlfriend ("I'm not on the pill"), only for her to reveal she used to be a man.
- Another has a man approach a suicidal woman whom he asks for a BJ before she jumps. After the act, he asks why she was going to jump. Turns out her parents disowned him for dressing up like a woman. So the guy jumps before the cross-dresser does.
- And a final one has a subway groper realize this. It ends up with the "and that's how you were born" Running Gag.
- The big reveal in chapter one of Lavender Legend is that Felicia, the tall and dour maid in the employ of Princess Lavender (and also La Résistance), is actually male, but was raised as a female by his mother in order to keep him from being conscripted into the kingdom's ruinous war that also killed his father. That doesn't stop Princess Lavender from enjoying their earlier first kiss... or from constantly tempting Felicia with sleeping in her bed.
- One Manly Guys Doing Manly Things comic has Jared unsettled and warning Commander Badass that Poison was, in his words 'a dude'. Commander Badass then points out that it shouldn't matter what a person has in their pants unless you're planning to get into them. He's more surprised that Jared thought he had a chance to score with Poison, gender aside.
- In the "Railway Children" arc of Skin Horse, Violet Bee tries to invoke this trope by revealing his gender to Tip. This plan falls flat because A) Tip was never particularly attracted to Violet and B) Tip is an Extreme Omnisexual.
- It was apparently a common occurrence for the flat-chested namesake of Shayla The Pink Mouse to be unknowingly picked up by gay men who thought she was a man until they got her to bed.
- Scandinavia and the World:
Sister France: Where did those breasts come from?! And where is the penis?!
- Averted. Denmark asks Thailand if he could buy 'the sexy lady' a cocktail, but Thailand admits he's Brother Thailand, not Sister Thailand. Denmark just wonders if that means he wants beer instead.
- And in another strip we have Sister France hitting on Sister Denmark (she thought that it's a handsome long-haired guy). And when they get to the action...
Sister Denmark: ...I don't know.
Sister France: I WANTED PENIS!!!
- A blatantly explicit one is seen in Moon Over June when Hatsuki (a highly promiscuous lesbian) barely makes it to the parking lot before she had that evenings hookup's head between her legs. When she went to return the favor....
"You picked me up in a transvestite bar! I thought you knew!
"I just had to go someplace new didn't I?"
- In Darths & Droids, this trope is used wonderfully with The Reveal. In this universe, Darth Vader is actually Padme Amidala, not Anakin Skywalker. When this bombshell was dropped during the RPing of The Empire Strikes Back, it totally waylays the entire team, who demand how this was possible.
- A common prank that people pull on the internet is to post a picture of a hot girl for everyone to ogle, only to reveal that the hot girl is really a very feminine man. Some goons at Something Awful did this by making a female Myspace profile with the lone picture of some cleavage, later revealed to be a guy pressing his manboobs together.
- All the hot women on the Internet that are actually guys posing as women online.
- Many online webcam pranks invoke this trope.
- This illustrated FML.
- The title Wholesome Crossdresser in The Saga of Tuck does this both when crossdressed and in his normal, baggy boy clothes. The latter tends to annoy him.
- Awkward. 4 has a flashback sequence of a series of Alex's ill-fated blind dates, one of whom is a man who stammers "Alex" in shock and quickly checks to confirm that, yep, that's an adam's apple before running for dear life.
- On the adoptable petsite Valenth, one of the NPCs is the person of intelligible gender of the week, Elliot Christoph. Considering many of the humanoid NPCs are like this, and all of them as such are men (plus the masculine name), many of the users expected Elliot to end up being male, referring to her as Sir Christoph and such. Elliot later is referred to as being female about twenty pages into the thread. The real kicker was the fact that she never bothered correcting them once. Lady looks like a dude indeed.
- DesuDesBrigade: Professor Otaku admits in his Quick Hits review of Gravitation that he didn't realize Shuichi was male until he was halfway through an internet porn search of "her".
Prof. Otaku: Well... wow, she really likes it in the butt. Hmm... Why does she... Oh.
- The Nostalgia Chick uses the Austin Powers "She's a man!" joke to express her doubts about Mel C being a real woman.
- In the The Cinema Snob review of Sadomania, he repeatedly remarks how beautiful the female warden is and checks the back of the box to find out her name...and discovers she is played by "the stunning transsexual adult film star Ajita Wilson". Cue a horrified "Oh my God" followed by a Smash Cut of him sitting in the shower fully clothed calling Jillian on the phone claiming that they have to have sex "right NOW" since he's "so confused". According to the video description, this was based on a friend of Brad's having had the same revelation.
- In the Key of Awesome parody of Carly Rae Jepsen's "Call Me Maybe," Carly meets a cute guy at the club. The two of them get drunk, then go to Carly's house and make out. The next morning, the guy wakes to find that Carly is actually a madman dressed as a young woman.
- Fairly common in the Chakona Space setting considering how many characters are Hermaphrodites. Perhaps the most notable example being when Garrek and Chakat Goldfur first started seeing each other and he spotted hir male parts and freaked. Though Garrek later apologized, saying he should have looked up Chakats on the net and realized that they were herms, and they got back together, so far they've got two cubs by one another.
- In Vaguely Recalling JoJo, Nena isn't a fat woman wearing the skin of another woman. Instead, Nena is a boy pretending to be a girl. Polnareff is shocked when he finds out.
- Zigzagged in the Dead West Porcelain Doctor; the narrator, a journalist named Gervas meets the titular porcelain doctor on a steamship, and concludes that the waifish, slim redhead with the creamy skin and the narrow waist ("like wearing a corset") and soft voice, wearing dainty glasses must be a crossdressing woman. He swores to protect the doctor, who is quite baffled, but accepts... then later, on a train, after a clash with "shamblers", the doctor disrobes a bit. Our narrator promptly tries to look away, but peeks a little, and takes a Double Take. The doctor was, in fact, a he. Not that this stops Gervas. Even better, almost everybody mistakes him for a girl. Carolina even grabbed his loins (cue minor freakout, from both parties), and wasn't too sure even after that!
- Not Always Learning has the story "New Meaning to Gender Displacement", where the submitter does this to a group of girls at her school ("OH, MY GOD! HE'S A GIRL!"). The sequel on Not Always Friendly has the same person do so again, in a different way; bonus points for the target being with her boyfriend, who started laughing hysterically in the aftermath.
- Discussed in an episode of Needs More Gay, where Rantasmo points out how hugely problematic it is that the vast majority of trans representation in media (which isn't very large to begin with), falls under this trope. Especially when the reaction of many male characters to discovering the girl they liked is actually trans is to throw up.
- Common for Phase in Whateley Universe, as he is an intersexed mutant whose body is mostly female (and extremely gorgeous) but who retains his original male gentalia, gender identity and sexual orientation. Unfortunately, more than a few males can't see past his appearance, and some (such as Imperious, who as the reincarnation of Zeus never gave much of a damn about the sex of his partners anyway) are actually more interested in him knowing that he's a 'she-male'.
- Subverted at the end of the first episode of Pop Quiz Hotshot, as General Anesthetic reveals that he used to be a woman. Critic's surprised, but he ends up wanting to be invited to the General's BDSM parties.
- SpongeBob SquarePants: Patrick does this in the episode "That's No Lady" to everybody in the Krusty Krab, including Mr. Krabs and Squidward who had fallen for "her" after he tears off the girl disguise he was wearing. (Take note that he strips himself butt-naked in the process, resulting even more Squick to both suitors.)
Squidward: Um...I think I need to take a shower.
- In the surprisingly serious short What's Opera, Doc?, Elmer Fudd finds out that the girl he fell for was Bugs Bunny in a dress — and actually kills Bugs with his magic helmet. Although it's unclear whether he does it because Bugs is male, or if it's because Bugs rejects him the moment the disguise is off! Or because, well, he's Bugs.
Bug: Well, what didja expect in an opera? A happy ending?
- Family Guy:
Joe: Taylor Hanson's a guy.
- Pervert Glen Quagmire gets quite an unsettling revelation when he tells Peter and the gang that if he could have any woman in the world, he'd choose Taylor Hanson from the 1990s band Hanson.
Quagmire: Oh! Oh! Y-you guys are yanking me. Hey, hey, let's put one over on old Quagmire.
Peter: No, he's actually a guy, Quagmire.
Quagmire: W-well, this is insane! That's impossible! Oh, my God. Oh, my God! Oh, my God, I can't... Oh, God! I-oh, I got all these magazines. Oh G-oh God! Oh, God!
Brian: And you had sex with two Filipino women. (sniffs again) And a man.
- Quagmire tends to get this trope fairly often. An episode where Brian is recruited by the force as a drug dog has Quagmire coming off a plane from Manila, where Brian comments:
Quagmire: You mean three Filipino women!
Brian: (Disapproving Look)
- In a similar vein, Brian, on the way home from a convention, goes to a hotel bar, meets up with a woman (who the audience knows the identity of), and they intellectually hit it off. After quite a few drinks he goes back to her room, and the next day is telling Stewie about his conquest...only to find that the woman he was with had all the correct parts now, but just a couple days ago was Quagmire's father; the main plot of the episode is the man going through a sex change operation and how everyone around was dealing with it.
- The Cleveland Show has a moment in the Thanksgiving special wherein Cleveland gets revenge on his wayward and emotionally abusive father by not telling him that the "woman" he's about to get in bed with is actually a man (and totally not Tyler Perry / Madea). As it happens, the "woman" in question is actually Uncle Kevin, who disguised himself as a woman so Donna would have a positive female role model after her mother passed away. And then when Cleveland DOES tell him, it's not heard, but you see the two men gesturing... then the dad vomits for thirty seconds.
Zapp Brannigan: Honey! Wait! You didn't show me your surprise!
- There is the Valentine's Day episode in which Zapp Brannigan is on a blind date with a very burly man in drag, who leaves unexpectedly early...
Zapp Brannigan: Leela! So it's you I've been attracted to! Oh, God, I've never been so happy to be beaten up by a woman.Leela: Let's do it again sometime.
- Inverted in "War is the H-Word," when Zapp finds himself attracted to "Lee Lemon." He is quite relieved when he finds out it was Leela all along.
- Also played with in Lrr (ruler of Omicron Persei 8)'s date with what he believes to be an Omicronian woman, who turns out to be a (human) cross-species dresser. He feels shocked and violated.
- Batman Beyond sees Ra's Al-Ghul transferring his mind into his daughter Talia's body... and Bruce Wayne has quite the history with her (Well, as much as he does with anyone). What transpires thoroughly creeps both Bruce and Terry out.
"I did not mean for you to find out this way. But I suppose what's done is done...DETECTIVE!"
Terry: Lady, that is the sickest thing I’ve ever seen! You’re creeping me out!Bruce: You?! She kissed me!
- And then later:
- Note that this is Batman saying this, and considering his career (which he is more-or-less retired from at this point), it should say a lot.
- In a later episode of King of the Hill, Peggy befriends a drag queen, after discovering "she" has size 16 feet like her. The reveal is unsettling for both of them since Peggy thought Carolyn was a woman and Carolyn thought Peggy was a drag queen.
- Done in a two part episode of South Park when Cartman, who's stuck in the future (long story, basically one of his usual schemes backfired), calls back to the past to reach Mr. Garrison who's recently had a sex change operation. Garrison is currently having sex with Richard Dawkins, Dawkins is the one to answer the phone and Cartman lets slip that Garrison is a post-Op. Needless to say Dawkins is repulsed. Not only that but by revealing this, it completely changes the future.
- In The Legend of Korra, Bolin falls for both of Korra's cousins, Eska and Desna, before Korra reveals that they're actually Half-Identical Twins- Desna is a guy.
- The Venture Bros..
- Inverted. Dr. Girlfriend tried to seduce Brock a couple of times. Brock thinks Dr. Girlfriend is a transsexual because of her masculine voice so it doesn't work. However the real reason she has a deep voice is due to her smoking habits.
- Inverted again. Doc never finds out Ginny is a woman because he's not even remotely attracted to her.
- in The Simpsons episode "Bart's Girlfriend", Bart hears angelic singing coming from the Springfield church, and assumes that it's Jessica Lovejoy. Turns out it's Ned Flanders.
Bart: Ughhhh. That's very disturbing.
- Near the end of the Danny Phantom episode "One of a Kind", he discovers up close that the rare purple-back gorilla "Samson" is actually a "Delilah". This is his reaction.
- Beavis and Butt-Head watch a Ru Paul video:
Beavis: Hey, Butt-head, that chick is pretty hot!Butt-head: Uhhh, ya think so?Beavis: Yeah, I'd do her in a minute!Butt-head: Huh huh, that's a guy, Beavis! Huh, huh, you wanna make out with a guy!Beavis: SHUT UP, BUTT-HEAD!
- Atomic Betty: At the end of the "No Business Like Snow Business" Betty gets on the boys' hockey team, unbeknownst to Penelope and her friends who swoon over "him" from the stands. Then Betty takes her helmet off. Penelope storms off angrily while her friends just laugh it off.
- In The Looney Tunes Show apparently even Sylvester thought Tweety was a girl until Tweety himself told him.
