Bob is really in over his head, now! He's surrounded by more mooks than he could hope to defeat on his own. Suddenly, a stranger in full armor comes from nowhere and makes quick work of the whole lot of baddies. The warrior then turns to Bob, takes off his helmet and... holy crap! It's a girl! Alice arrives!

'''Samus Is a Girl''' is when an [[Action Girl]] is well established as heroic or otherwise [[Badass]] before the first hint that she's female. Whether the initial lack of discernible sex is caused by bulky armor, baggy robes, [[Wholesome Crossdresser|subtler deliberate deceptions]], shapeshifting, or even just the camera refusing to give a clear shot of any distinctly female parts of her, it's still Samus Is A Girl. Heck, a tank with a chick inside would count. Having a [[Tomboyish Name]] helps as well.

Oftentimes, Alice will only wear the form-concealing outfit during her introduction. Afterwards, it may end up getting lost or destroyed, and thereafter she wears something a little less ambiguous. Sometimes, she just stops on her own.

This trope is notably harder to pull off in some languages - those that don't use gender-neutral descriptors that much. (On the other hand, it's ''very'' easy to pull off with some foreign characters, since quite a few Japanese and African names can be assigned to either gender.) It's one thing to say Samus is a bounty hunter, but when your language demands that if the gender is known, this should be bounty huntress, characters that ''do'' know about Samus' gender and just don't care to elaborate to the listener couldn't just call her a bounty hunter without stretching suspension of disbelief. It's one thing to trick the viewers by clever terminology, but when you break your language to do it, the effect becomes not so much "Hey, that's right, the gender was never actually mentioned!", but "Um... so the character who was referred to as male by others who knew she was female all the time was actually female. Huh?".

Thanks to pervasive [[Double Standard]]s, a previously-thought female revealed to be male is most-guaranteed to be classified as an [[Unsettling Gender Reveal]], while the opposite (this trope) acts as a "Comfortable Gender Reveal". In fact, straight gals and gay guys would almost certainly think the reverse.

Compare to [[The Faceless]], [[Sweet Polly Oliver]] ('''Samus Is a Girl''' from a viewpoint that already knows she's female) and [[Viewer Gender Confusion]] (where the audience, not the characters, don't know what gender Pat is). See also [[Geeky Turn On]], which is sometimes related to this. Depending on how it's written, [[The Reveal]] could end up being a [[Tomato Surprise]].

{{unmarked Spoilers}} '''The fact the title of this trope gives an example is a pretty good reason why this trope should not be spoiler tagged, right?'''

{{examples}}
== [[Trope Namer]] ==
* Named for Samus Aran from ''[[Metroid]]''. In the first game, the player doesn't learn she's female until after guiding her through an army of alien baddies. Later games in the series still play with this trope. The Prime series, however, does not play with this, and gives her a rather feminine figure considering she's in armor. [[Other M]] completely throws away this trope, however, because you see Samus without her suit in the opening sequence, in many cutscenes (sometimes this is just a shot of her face through her visor), and in the death sequence.
** The [[Easter Egg|cheat code]] "[http://metroid.wikia.com/wiki/Justin_Bailey Justin Bailey]" entered in the first game, will start Samus near the end of the game, with no armor on.
** The death sequences in ''Super Metroid'', ''Metroid: Fusion'', and ''Zero Mission'' also have her armor shattering and reveal her form underneath. Plus, ''[[Super Smash Bros.]] Melee'' gives her a sleek version of the Varia Suit.
** In the original game, even the ''manual'' refers to Samus as male. The developers only came to the decision to make her female about midway through the production process, when one of them casually remarked that it would be really funny to get to the end and discover she was a girl all along. Possibly one of the greatest instances of [[Throw It In]] in video game history.
*** The second game's manual, however, uses "she" throughout. A literal case of [[All There in the Manual]], only confirmed by the best ending. (Later games do much the same.)
** In ''Metroid: Zero Mission'', you get a visor shot right before the game begins, but if you're not paying attention, you'll miss it. Hilarious, given that ''Zero Mission'' is a redone and updated version of the original game.
** Naturally, this happens to our favorite Spartan in ''[[Haloid]]'' as well. Wait....  {{spoiler|Surprise! That's not Master Chief, but Nicole-458, a female spartan who appeared in the Dead or Alive games (even though there was no canon on ''how'' Nicole looked like). She ends up pulling this trope on Samus, making Haloid a double whammy.}}
*** And it's not just in fan fiction! [[Canon]] ''Halo'' media uses the exact same trick not once, but twice - {{spoiler|Maria-062}} in the ''Halo Graphic Novel'' and {{spoiler|Cal-141}} in ''Halo Legends''.
** Played with a little bit in ''[[Super Smash Bros.|Super Smash Bros. Brawl]]'', if the player fights her as [[Metal Gear|Snake]] on Shadow Moses Island. In his codec transmission, Snake remarks to Otacon that he's fighting "a woman in a power suit." Otacon is baffled as to how Snake can possibly know she's a woman. Snake's comments in this transmission, and in the one he makes if he fights her in her Zero Suit, are the main reason Snake/Samus has become a popular ship among the fans.
*** Hint: He figured it out by watching how she walks - [[Male Gaze|and checking out the anatomy involved]]. This is a shout out to how the player finds  {{spoiler|Meryl in disguise in ''[[Metal Gear Solid]]'' - exaggerated hip sway}}.
*** These conversations may also be subtle foreshadowing of the Power-Suited [[Amazon Brigade]] that would appear in ''[[Metal Gear Solid 4: Guns of the Patriots]]''. It's not the only thing Kojima foreshadowed in that game.
** Also played with in Melee, where Samus's main trophy's description doesn't use any pronouns.
** When ''Metroid'' first came out in the 80s, Nintendo USA ran a ''Metroid'' art contest in their magazine "the Nintendo Fun Club News" (a precursor to "Nintendo Power"). All the winners who had Samus unmasked in their art depicted her as a man.
*** [http://a7.sphotos.ak.fbcdn.net/hphotos-ak-ash4/s720x720/420818_2815298616014_1065280239_32236295_1052113179_n.jpg This is the art in question.]{{broken link}} Notice the one that was tied for 4th. This was obviously based off an ending in the game, [https://web.archive.org/web/20120514131436/http://images.popmatters.com/blog_art/s/samus_helmet.png in which Samus' face was the only thing that was revealed.] Thanks to the 8-bit graphics, it was STILL impossible to tell whether or not Samus was a girl. One could easily interpret that the person in the suit was simply a guy with [[Eighties Hair]]. Apparently, the artists settled for that notion. Seems that the judges of the art [[Did Not Do the Research]] and did the same. Either that, or Nintendo knew beforehand and decided to make the judges disqualify the entries that depicted Samus as a female in order to keep the twist ending a secret.
** In the ''[[Captain N: The Game Master]]'' [[Nintendo Comics System|comic book]], Samus was a regular character, and in her first appearance it surprised the regulars from the cartoon when she unmasked for the first time. The scene in question is quoted above.

== [[Anime]] and [[Manga]] ==
* In the new ''[[Halo]] Legends'' anthology, the episode "The Babysitter" uses this trope for the SPARTAN sniper.
** Which in turn is based off of one of the EU novels.
* Marlene in ''[[Blue Gender]]''. Yuji is her "Bob".
** He's more surprised by the fact that she's human than the fact that she's female. Waking up in the middle of a [[Bug War]] and seeing nothing but [[Nightmare Fuel]] for a solid 5 minutes can do that to you.
* In the "Battle Tendency" arc or ''[[JoJo's Bizarre Adventure]]'', Joseph Joestar and Caesar go to meet Caesat's mentor. When Joseph finally mets her, she is initially fully dressed and her face is concealed, and he thinks she must be a man... until she reveals her face.
* Rei in the manga version of ''[[Neon Genesis Evangelion]]''.
** That is, when Rei's still inside the Eva. [[Fog of War|In the confusion of the battle]], Shinji can't tell if anyone ''is'' inside the Eva (Rei's name comes up, but that seems to be a thought bubble rather than spoken dialogue on Misato's part). Shinji does cry out (in the English translation), "Our guy's getting clobbered!" But when he gets to NERV headquarters, he still seems to think he was saved by a robot. At any rate, as soon as the reader—and, a few panels later, Shinji—actually ''[[The Reveal|sees]]'' Rei, it's clear she's a [[Bandage Babe]]—along with all sorts of other types of [[Fan Service]] [[Your Mileage May Vary|/]] [[Fan Disservice]].
*** Also worth noting: while the feelings that develops between Shinji and Rei are not entirely platonic, they never have any sort of outright romantic relationship either. Given [[Incest Is Relative|Rei's origins]], that would be all sorts of [[Squick]].
**** Carefully averted in ''[[Rebuild of Evangelion]] 2.0'' with Asuka, who arrives in Unit 02 to fight the Angel. Shinji had never seen her or her Eva before but when he does comment on the battle, he doesn't use any third-person pronouns in either the Japanese original or the English dub.
* In ''[[Berserk]]'' Guts doesn't realize that Casca who is in full medieval knight armor is woman until he knocks off her helmet.
** Later at a formal celebration Guts is approached Casca now dressed in, [[Incredibly Lame Pun|well, a dress]], despite knowing very well that she's a woman, Guts is awfully surprised to see her looking like one, likely used to her being one of the guys.
** Even later when the Hawks plan to  {{spoiler|rescue Griffith}} their guide is none other then Princess Charlotte who admits not realizing that she was a woman the first time they meet (much to Guts and Judeau's amusement).
* When most people hear of the assassin ''[[Noir]]'', the assume it to the be the codename for a ''male'' assassin, as opposed to the fact that it is actually ''two'' girls.
** Especially ironic, since eventually it's revealed that Noir in fact originally referred to two female killers as long as thousand years ago.
* In the ''[[Giant Robo]]'' [[OVA]]s, [[Action Girl]] / [[Cool Big Sis]] Ginrei first appears in disguise as a [[Mask Power|masked]] [[Badass Longcoat]] to rescue Dr. Shizuma—for all of a minute, before [[Flung Clothing|suddenly changing]] into her trademark Chinese dress, and never using the "Iron Mask" disguise for the rest of the series.
* Cagalli Yula Athha of ''[[Mobile Suit Gundam SEED|Gundam SEED]]''s [[Tsundere|tomboyish personality]] and androgynous clothing originally fools both Kira and Athrun into thinking she is a boy.
** Cagalli's gender confusion is also an in-joke to the viewers; [[Hey, It's That Voice!|Naomi Shindou]] usually voices young boys.
** It doesn't help that all the characters in ''SEED'' [[Only Six Faces|have the exact same facial features, even across genders]].
** That'll be [[Painting the Fourth Wall|extradimension hit]] both for characters and Viewers, hence...because [[Only Six Faces]] rule we missed the part that [[Half-Identical Twins|Cagalli is Recolored Kira!]] and hence... [[Ship Tease]]
*** Cagalli is actually  {{spoiler|[[Separated at Birth|Kira's sister]]. Making this at once [[Fridge Brilliance]] (albeit unintentional) and [[Squick]] [[Ship Tease|Tease]].}}
* In ''[[Ranma ½]]'', Akane exemplifies the trope when {{spoiler|she dresses up in full kendo outfit and protection and participates in a males-only match against Tatewaki Kuno. It is only after girl-Ranma declared her love for whoever was in there and then her mask falls off (long story) that the audience and Ranma realize that they had been cheering for Akane all along.}}
** A more handy example lies with Ranma's [[Unlucky Childhood Friend]] Ukyou. Having met her at a very young age, Ranma always believed her to be another boy; after a bitter grudge match in which she forced him to fight "seriously", he was stunned to discover she was actually a girl. [[Hilarity Ensues]]:
{{quote|'''Ranma''': Since when are you...
'''Ukyou''': ...a girl? Since I was born, idiot.
''(Ranma pours hot water on her)''
'''Ukyou''': Ow! Hot! Hot! Hot! ''(punches Ranma)'' Why the heck did you do that?!
'''Ranma''': Hey, you didn't turn into a man!?
'''Ukyou''': What's that supposed to mean? Listen up and well! I'm a hundred percent woman!!! }}
** Exemplified and subverted ''again'' by the character Herb. When the tall, dark, powerful stranger who handily defeats is shown to be a woman, the cast reacts with surprise and shock. However, the subversion comes as it turns out that Herb is the ''Prince'' of the Musk Dynasty, who, having fallen into the same cursed spring as Ranma, also turns into a woman.
** This is then inverted by [[Dude Looks Like a Lady|Konatsu]] and [[Master of Disguise|Tsubasa]], [[Wholesome Crossdresser|Ukyou]]'s would-be suitors who ''everyone'' (including the audience) believed to be girls, right up until the very final page of their introductory story arcs—when [[Clothing Damage|their outfits]] are destroyed, one way or another. To be fair to Ukyou, she ''did'' know Tsubasa's true gender... she just [[You Didn't Ask|didn't bother telling anyone]].
* In ''[[Bleach]]'', (read only if you've seen Episode 41 or read Chapter 116) {{spoiler|Yoruichi}} is a more long and drawn out version of this; {{spoiler|as long as she remains in cat form}}, everyone assumes she's a man. In the manga, this was just an assumption on the part of the reader. The anime is more deceptive; {{spoiler|they gave cat-Yoruichi a really masculine-sounding voice}}. It doesn't help that she has the speech patterns of an old man.
** {{spoiler|Cat-Yoruichi is supposed to sound masculine; in the manga, she tells Ichigo that most people who only know her as a cat think she's male because of her voice.}}
**  {{spoiler|[[Hilarity Ensues]] when [https://www.youtube.com/watch?v=ZHHPWXtwLLs she reveals that she is a girl]. Doesn't help that she's also a [[Shameless Fanservice Girl]] and the revelation is a [[Naked First Impression]] for Ichigo.}}
* In the anime ''[[Bastard!!]]!'' Arshes Nei was shown at first as a figure in full plate and rather bulky armor, which made impossible to tell that the character within that armor was, in fact, a slender female.
* {{spoiler|Mukuro}} from ''[[Yu Yu Hakusho]]''. She even disguises her voice and covers her face when she is first introduced. {{spoiler|She also refers to herself with the ''very'' masculine pronoun "ore" in Japanese, and, believe it or not, Hiei is her Bob.}}
* One episode of ''[[Excel Saga (anime)|Excel Saga]]'' concerns a mysterious masked man with a masculine voice. He and Nabeshin have a lot of [[Ho Yay]], which Excel comments on - and then the mask is removed, showing a beautiful blond woman. [[Rule of Funny|Still with a masculine voice.]]
* A bit of a drawn-out occurrence appears in ''[[Katekyo Hitman Reborn]]!''. It is pretty much impossible to tell I-pin's gender, since she is a baby... Then she gets hit with the 10-year Bazooka. No romance (again, baby) but she ''does'' spend a lot of time with Lambo.
** You think them being [[Toy Ship|babies/kids has stopped the Lambo X I-Pin]] [[Shipping|shippers]]?
* Haruka in ''[[Sailor Moon]]'', although there's no romance arc beyond her flirting with Usagi for the fun of it; she's already taken... by a woman, which helped hide her gender. Though due the fact that she appeared in the anime in her Senshi form before the reveal at the end of the episode introducing her, viewers are not as shocked as the characters. (It should be noted that before this episode, Uranus and Neptune DID show up in senshi form, but all the viewer was shown was a silhouette and the credits only listed them as "Mysterious Senshi 1 and 2"
** Also, for the first few Uranus and Neptune appearances in the original manga, they were perceived not as two mysterious senshi, but as a mysterious senshi/Tuxedo Mask pair; and Haruka's flirting with Usagi was much heavier. It wasn't until after they joined with the other senshi that Uranus was perceived as a woman rather than a man.
* Lan Fan in the ''[[Fullmetal Alchemist]]'' manga. When Ed uses alchemy to destroy her mask in their fight, he's so shocked to see she's a girl that she's able to both destroy his automail arm and drop a bomb before he can react.
** Subverted the subtrope by not becoming Ed's love interest at all. In fact, she [[Bodyguard Crush|already has her own]] (there was a brief, mostly-played-for-laughs [[Ship Tease]] between Lan Fan's love interest and Ed's, though).
** Also Major General Olivie Mira Armstrong, when Alex first mentions her, she could have been a male as well.
* Kidd Summers at the start of the ''[[Pokémon (anime)|Pokémon]]'' movie: "Lucario and the Mystery of Mew", literally in armor. Semi-justified by the fact that ''everyone'' at the festival is in quasi-medieval costume.
** {{spoiler|Yellow}} in the manga ''[[Pokémon Special]]''. Funnily enough, only Blue and Blaine knew until near the end of the Gold/Silver/Crystal arcs, then ''everyone'' finds out after {{spoiler|she removes her hat}}.
*** Green found out while training her. The only ones shocked by that spoiler were Red, Crys, and later Gold.
** Anabel and Angie in the main anime. Incidentally, they both end up developing a crush on Ash.
** Zoroark turns out to be female in the movie.
* Due to the voice acting in the dub, German viewers often thought ''[[Digimon Tamers]]'''s Renamon was supposed to be "male" (or at least gender-neutral—it's a somewhat deliberately enigmatic digital lifeform in what's arguably a kids' show, after all). Which makes the final form a bit of a surprise.
* Parodied in ''[[Steel Fist Riku]]''. Chikara Toudou arrives to challenge Riku's father, but since he's not around, he decides to challenge the "son", Riku, instead. At this point, Riku has her chest bound flat, so it's understandable. But then, Riku tells him she's a girl, and he accuses her of pretending to try and get out of the fight. Then, during the fight, he notices the bump under Riku's shirt... and thinks "he" is concealing a weapon there. He finally gets it after he grabs her breast.
* Odd variation in the ''[[Mahou Sensei Negima]]'' manga: Earlier in the manga we met Paio Zi, a member of a group of bounty hunters pursuing Nodoka had a rather... "healthy" appreciation for <s>breasts</s> boobies that bordered on the obsessive. Most readers found this character ''quite'' [[Dude, Not Funny|disturbing]]... until a recent chapter mostly [[Furo Scene|set in a bathhouse]], where the hunters are encountered again under peaceful circumstances, and Paio is revealed to be a girl, who proceeds to [[Skinship Grope]] the hell out of pretty much everybody within reach (and she moves ''fast''), to the amusement of the fans. This comes across as a bit of a [[Double Standard]], but she's really a lot less threatening without her fighting costume, which is rather monstrous and effectively ''quadruples'' (at least!) her body mass. Compare her [https://web.archive.org/web/20170718142504/http://www.onemanga.com/Mahou_Sensei_Negima!/218/06 in costume] (Commanding the tentacled worm) with her [https://web.archive.org/web/20170718140904/http://www.onemanga.com/Mahou_Sensei_Negima!/235/07 out of it] (Furo, remember? so may not be Work Safe).
** What [[Double Standard]]? Ku Fei didn't hold back when she kicked Paio in the ''face''.
*** Mostly by the fans, who were creeped out by Paio Zi at first, but then laughed their heads off when the truth came out.
**** There is a difference between [[Skinship Grope]] and what seems like attempted rape.
* [[Enigmatic Minion]] Masquerade of ''[[Bakugan]]'' is actually {{spoiler|Alice}}. She uses her [[Stat-O-Vision]] [[Sinister Shades]] [[Mask Power]] to transform.
* Noi of ''[[Dorohedoro]]'' does this in the first volume. She's one of the numerous masked [[badass]]es of the show; taller, bulkier and probably stronger than the entire male cast.
* Stir from ''[[King of Bandit Jing]]'' does this.
* In ''[[Revolutionary Girl Utena|Adolescence of Utena]]'', Saionji cuts Utena's shirt in their duel, leading to the following exchange:
{{quote|'''Saionji:''' You're a girl?
'''Utena:''' [[You Never Asked|I don't remember saying I was a boy!]] }}
* In the ''[[Dragon Quest|Dragon Warrior]]'' anime, [[Action Girl|Daisy]] saves [[The Hero|Abel]]'s hide a few times before he finds out she is a girl.
* ''[[Fist of the North Star]]'' has this pulled off by the Last General of Nanto, who dresses like a fearsome warlord. Once the helmet comes off though, the General is revealed to be none other than {{spoiler|Yuria, who was presumed dead at the time.}}
** A [[Establishing Character Moment|baddass]] inversion was used in Rei's debut. You see a woman in a pink cloak being harassed by thugs. You think a badass martial artist'll jump in and save the day. Then you end up surprised when the "woman" in the pink cloak turns out to be said martial arts badass Rei in disguise, luring said thugs to him.
* Raiko Minamori in ''New [[Getter Robo]]'', who is revealed to be a woman only after Ryoma tackles her and [[Accidental Pervert|ends up grabbing a handful]].
* In ''Getter Robo Armageddon'' At the beginning of the series the kid is daughter of Dr.Saotome initially using boy's clothing. {{spoiler|After missile fall to Earth events, Genki Saotome is adopted by Benkei and revealed that he is a girl and having her name changed to Kei Kuruma.}}
* Reversed in ''[[Liar Game]]'' in the second round {{spoiler|where the seemingly innocent "Yuji" is revealed to be the cross dressing Mr. X.}}
* ''[[Ouran High School Host Club]]'': Haruhi, if you watch the first episode [[It Was His Sled|unspoiled]], which is pretty much impossible nowadays.
* ''[[Glass Fleet]]'' combined this with [[Viewer Gender Confusion]] due to the fact that {{spoiler|Michel}} had a {{spoiler|female}} voice actor. The big reveal isn't until episode seven. Afterwards, {{spoiler|her}} style of dress does not change (spoiler text as this is a major plot point of the series).
* ''[[Yu-Gi-Oh!]]'':
** [https://yugipedia.com/wiki/Gravekeeper%27s_Assailant Gravekeeper's Assailant] in ''[[Yu-Gi-Oh! GX]]''; nothing about the OCG card suggests a female, though the anime [https://yugipedia.com/wiki/Yasmin (where she is seen unmasked)] shows otherwise. 
** In ''[[Yu-Gi-Oh! 5D's]]'', the helmeted D-Wheeler shown in the third intro sequence turns out to be a blond woman named Sherry. Not that it's all-too hard for the viewer to figure it out quickly, with the [[Action Girl]] and floral theme of her deck. 
* ''[[Kino's Journey]]'': {{spoiler|[[Ambiguous Gender|Kino]] is a girl. The anime doesn't tell you until the fourth episode and you don't find out for quite a while in the non-English novels, before which most viewers tend to either assume she's a boy or think "But he could be...". The people who figured it out before hand got to give themselves a good pat on the back when her gender was finally revealed.}}
** Strangely, it is Japan in which this is easy to guess due to seemingly [[Cross-Dressing Voices]], the English dub gives the character a much more ambiguous voice.
*** Though it's not uncommon in anime for adolescent males to have distinctly effeminate voice.
* ''[[Full Metal Panic!]]'': In the Second Raid, Mithril agent Wraith is revealed to be woman. She disguised herself was an overweight man complete with a voice changer.
* With Hinagiku taking the role of Silver Red (a superhero of a Sentai parody), ''[[Hayate the Combat Butler]]'' is setting itself up for this one. The other characters even think Red ''is'' a guy, despite the significant lack of male form ([[Berserk Button|not just Hina's]] [[Pettanko]] status).
* In ''[[Kirby: Right Back at Ya!]]'', Princess Rona initially introduces herself as the MALE bodyguard Vee to the decoy princess because she wanted to get to know the people of Cappytown as a normal person. It's not until her helmet falls off later on that any real girlishness is revealed. She still manages to kick Dedede's ass at the end in a swordfight even after being revealed as the actual princess. Though in this case, the deception was intentional, not just that wearing that particular suit or whatever was the most logical thing to do for an action hero.
* Busujima from ''[[Busou Renkin]]''.
* A [[wikipedia:The Three Musketeers (1987 TV series)|1987 anime version]] of ''[[The Three Musketeers (novel)|The Three Musketeers]]'' does this to {{spoiler|[[Gender Bender|Aramis]]}}.
* In ''[[Death Note]]'', Misa Amane is revealed to the readers to be the second Kira soon after her activities become known to the other characters. In the English versions at least, Light and the investigators continue to refer to The Second Kira by the male pronoun (probably for the sake of convenience, as they use "he" when referring to the first Kira too) until they learn more about her.
* Played with in ''[[Space Pirate Mito]]''. During a fight, [[Big Bad]] Ranban's helmet is knocked off, revealing not only a female face underneath, but the same face as Aoi's mother, the titular Mito. Ranban reveals that it's just a [[Powered Armor|mail suit]], which Mito also wears, modeled on the first queen of the galaxy. Later on, however,  {{spoiler|it's revealed that Ranban never differentiated between genders, as his species usually does at puberty, and is thus a [[Hermaphrodite]]}}.
* ''[[One Piece]]'': 
** In the fourth movie, the little kid whom Luffy and Co. encountered was revealed to be a girl dressed in boy's clothing near the end.
** The series seemed to be heading this way with the famous Dr. Vegepunk. At the start of the Egghead Arc, the first important character the Straw Hats met was a young woman who claimed to be Vegepunk. This character - Lilith - was technically telling the truth, seeing as she is one of Vegepunk's "satellites", androids built as extentions of Vegepunk who share the same brain. However, Vegepunk's original body is, as expected, male and much older than any of his satellites. 
* {{spoiler|Sevotharte}} from ''[[Angel Sanctuary]]''. The promising scientist  {{spoiler|Lailah}}'s success elicited jealousy from her male peers, who [[Rape as Drama|raped her]]. Branded a Fallen Angel for becoming "tainted", she sold herself in desperation to [[Fetus Terrible|Sandalphon]], who [[White-Haired Pretty Girl|whitened her hair]] and altered her face and body type. Since the true {{spoiler|Sevothtarte}} died years ago in combat, she took his name {{spoiler|and wore a tiara and veil}} to hide her identity after she ascended into the Seraph rank.
* Used during the ''[[Naruto]]'' Land of Birds filler arc. An armored, flying specter wielding a naginata appeared to haunt a daimyo's castle which had recently seen great misfortune; the specter seemed intent on uncovering if an assassin had slain the former daimyo and his daughter. It was eventually revealed that the specter was  {{spoiler|in fact the new daimyo who had assumed lordship, and that said daimyo was in fact the ''daughter'' of the dead daimyo and had been posing as her also dead brother}}.
** Subverted much earlier during the Land of Waves of arc. Haku's first appearance showed [[Dude Looks Like a Lady|her]] to be highly-skilled and convinced even Kakashi that [[Wholesome Crossdresser|she]] was a threat while wearing bulky robes that could disguise a feminine form. A chance meeting with Naruto while in civvies set up the possibility of a forbidden romance... and then Haku [[Dropped a Bridget On Him]].
* In ''[[Durarara!!]]'', Celty's gender isn't clear when she first appears thanks to camera angles and lighting, although her feminine form is much more apparent later on.
** It's apparently less obvious in-universe than it is to the viewers; neither Shizuo nor Tom knew that Celty was female until Shinra told them.
*  {{spoiler|Melk the Second}} from Toriko starts off appearing to be a very [[Bishonen|bishie man]].
* ''[[Ice Revolution]]'': Most of Masaka's friends at the skating rink thought she was a boy... until she took the ice for her first performance. Heck, her own coach didn't even notice she was a girl until she told him.
* The red man in ''[[Deadman Wonderland]]''. Ganta is so screwed when he found out the nemesis he hated so much turns out to be {{spoiler|his childhood sweetheart Shiro.}}
* Kei in ''[[Iria Zeiram the Animation]]''. She's pre-adolescent, so there's no way to distinguish that she's a girl dressed in boy's clothes until late in the series when Fujikuro literally sniffed out her gender.
* In episode 12 of ''[[Blue Exorcist]]'',  {{spoiler|Yamada who always wore a hood and never spoke, turns out to be Stripperific [[Action Girl]]. Apparently being a ''Vatican'' High Inspector requires you to wear ultraskimpy bikini tops.}}
* The titular character in [[Osamu Tezuka]]'s {{spoiler|Dororo}}. It doesn't help that she was told she was boy by her parents.
* In ''[[Sgt Frog]]'', many characters first think that Private Tamama is a female due to his cute appearance and voice. Later on in the series, Tamama himself, along with most of the rest of the cast, falls victim to this trope when a Keronian named Karara comes to Earth to see the ARMPIT Platoon. It's not made apparent that she's female until she leaves a goodbye note when she leaves at the end of the episode, saying that Tamama left such a huge impression on her that she wants to marry him when she grows up. In all the character's defense, an actual female Keronian hadn't shown up before then.
* Brilliantly pulled in ''[[Infinite Stratos]]''. Ichika accomplishes the impossible and moves an IS, something that's said to be impossible to be done by males. He gets himself enrolled in an all-girl school... then after a while, another male by the name of [[Bishonen|Charles]] [[Cute Shotaro Boy|Dunoa]] is transferred into the class and said to have accomplished the same feat. Dunoa is awfully shy around Ichika in the locker room and {{spoiler|refuses to change with him, something Ichika finds quite strange and tries to lightheartedly force the issue, only to provoke the other boy into running away. When he returns to their mutual room, [[Shower of Awkward|Dunoa is in the shower and Ichika enters the bathroom just as Dunoa leaves the cubicle]].}} Yup, [[Sweet Polly Oliver|Dunoa]] is [[Full-Frontal Assault|definitely not a guy]]. "He" later explains that {{spoiler|as an illegitimate child, she was kept in secrecy until a few years ago when she was tested and found to have a good aptitude at using an IS. Her [[Wholesome Crossdresser|disguise]] as a boy served two reasons: first, as a publicity stunt to her father's company which was falling behind in IS development and second, as a way to [[The Mole|get close to Ichika and spy on him]].}} A few days later, Ichika's class receives another transfer student. Everyone, say hello to [[Moe|Charlotte Dunoa]]. Naturally, everyone in the class knows Charlotte and Ichika used the bathhouse together the previous night and instantly make the assumption he must've known and [[Accidental Pervert|took advantage of it]]. Cue [[Yandere|Rin]] [[Pervert Revenge Mode|bursting into the classroom with her IS and firing a full-powered shot at Ichika's head]].
** And as a little extra, Charles/Charlotte also happens to be a [[Char Clone]] and later becomes a [[Love Interest]] for Ichika.
*** And as a litlle extra extra, her nickname, given to her by Ichika, IS Char. Go figure.
* ''[[Fushigi Yuugi]]'' has Soi, who was a person wearing a cloak for a few chapters before revealing herself as a woman.
* A villainous example appeared in ''[[Brain Powerd]]'' - the enigmatic Baron who begins to appear late in the show is quite fearsome, helping the villain Jonathan transform his [[Humongous Mecha|Grand]] [[Empathic Weapon|Cher]] into a borderline [[Eldritch Abomination]] known as the 'Baronz'. His reasons seem mysterious and [[Chessmaster]]-y, but...  {{spoiler|behind the mask, it's actually Jonathan's estranged mother, trying to protect and help her son despite being stuck on the wrong side of the conflict from him.}}
* Inverted in ''[[Baccano!]]'', where Claire Stanfield, the expert assassin named Luck had hired, turns out not to be the [[Red Herring|fatigues-wearing]] [[Action Survivor]] woman [[Red Herring|that'd been making her way across the train]], but rather {{spoiler|[[Red Herring Shirt|the redheaded conductor that was supposedly killed off very early on in the story.]]}}

== [[Comic Books]] ==
* One of the regular supporting heroes in Paul Grist's ''[[Jack Staff]]'' is Tom Tom the Robot Man, a towering, super-strong robot with the power of flight. It's a genuinely bizarre and unexpected moment when it's discovered that "he" is effectively a suit of powered armour being piloted by a disabled girl genius to fight crime.
* In the one-shot crossover "[[Spider-Man (Comic Book)|Spider-Man]] vs. [[Wolverine]]", both heroes are on the trail of Wolverine's former partner, named "Charlie", which is given as being short for: "Charlemagne". When Wolverine finally catches up with Charlie, the rogue agent is revealed to be a "she". Wolverine naturally knew all along, but Spidey, as well as the READER were kept in the dark by clever avoidance of gender-specific pronouns (not to mention a flashback where "Charlie" is deliberately shown in gender-neutral disguise). It's implied that Charlemagne uses the ambiguous nature of her name as an additional cover to her identity.
* In ''[[X-Men (Comic Book)|X-Men]]'', Professor X's primary love interest Lilandra was introduced in a running subplot in which he was having ominous visions of space battles and a menacing armored figure. When the figure finally showed up and took off its helmet, it wasn't quite what he was expecting.
* The original Ronin in ''[[The Avengers (Comic Book)|New Avengers]]'' turned out to be [[Daredevil]]'s love interest Echo (after a minor [[Red Herring]] that it was DD himself).
* Julie-Su from the ''[[Sonic the Hedgehog (comics)|Sonic the Hedgehog]]'' comic.
* {{spoiler|Mindf**k}} of ''[[Empowered]]'' is a dramatic example, as eventually revealed to Emp; {{spoiler|Mindf**k}} and {{spoiler|Sistah Spooky}} are ex-lovers, whose first meeting (without a Samus Is a Girl scene) was shown in flashback the following volume.
* {{spoiler|Junior, who is assumed to be Ragdoll's brother or father}} in ''[[Secret Six]]'', turns out to be his {{spoiler|sister}}.
* Sasquatch from ''[[Alpha Flight]]'' is ''usually'' male in the main continuity, but in the [[Ultimate Universe]], when the team returns to base after fighting the X-Men, Sasquatch resumes human form and turns out to be the very female Rahne Sinclair, who in the main [[Marvel Universe]] is the werewolf Wolfsbane. There were some hints to this beforehand though; readers may have wondered why "he" had [[Tertiary Sexual Characteristics|ribbons]] in "his" hair in Sasquatch form.
** Sasquatch from ''The Exiles'' as well. First going into human form: "What surprises you more, that I'm a woman or that I'm black?"
* An early arc of ''[[Wolverine]]'''s solo comic involved an up-an-coming crime boss in Madripoor called Tyger-Tiger challenging Roche's hold on the nation's underworld. Roche had no idea who Tyger-Tiger was, and in one part, believed it was a male rival. In truth, Tyger-Tiger was [[Dark Action Girl| Jessan Hoan]], and as a result, her final assault on him came as complete surprise.
* Shining Knight, from [[Grant Morrison]]'s ''[[Seven Soldiers|Seven Soldiers of Victory]]'', is revealed to be a girl at the end of her portion of the series.
* Colonel Randall in Dark Horse's early ''[[Terminator]]'' comics is introduced as a gritty soldier in combat fatigues and a face-obscuring helmet, and only referred to as 'the Colonel'. This is really only to build up to the money shot, where, after having stripped down to go through Skynet's time machine, Colonel ''Mary'' Randall blows away a terminator and is shown to be... a hot nekkid babe! Needless to say, on arriving in the 20th century she starts wearing tight minidresses.
* In ''[[The Sandman]]'', Death's name is mentioned well before we see her. Gaiman intended for most readers to assume Death of the Endless would be male and menacing ... until we saw her.
** [[Squick|In-character example]] from the same series:  {{spoiler|"[[Serial Killer|Dog Soup]] is a ''woman''?"}}
* ''[[The Surrogates (comics)|The Surrogates]]'' features a setting where normal people no longer interact with each other in person, but instead use a [[Unusual User Interface|humanoid robot]] as a proxy. As a result, cross-gender surrogates are common. One of the first surrogates we see is a cross-gender surrogate, and the male [[Corrupt Corporate Executive]] is revealed to actually be a woman. Both of them masqueraded as a person of the opposite gender to get ahead in their respective fields.
* In ''[[Camelot 3000]]'', Merlin sends Tom to a wedding to awaken the memories of a reincarnated Round Table knight. The homing-amulet he's carrying leads him to the couple at the altar. Tom assumes it's the groom he's looking for, but it's [[Gender Bender|actually the bride]] whom Sir Tristan has been reborn as.
** Of course, the now awoken Tristan fully identifies as a man and draws a great deal of angst from it.
{{quote|My name is Tristan. '''Sir''' Tristan.}}
* Taz in the ''[[Atari Force]]'' second series was referred to as being male up until Morphea discovered {{spoiler|Taz was pregnant}}.
* In ''[[Scud the Disposable Assassin]]'', Sussudio is introduced this way. {{spoiler|Naturally, she later becomes Scud's love interest.}}
* The magazine ''[[Heavy Metal (animation)|Heavy Metal]]'' ran an [[Weird West|Old West fantasy]] mini-series, "Tex Arcana." One of its characters was the [[Camp Gay]] Buffalo Wade, whom no cowpoke would try to beat up because Wade was such a [[The Gunslinger|deadly fast and accurate shot]]. The finale revealed (to the readers only) that "Wade" is actually a [[Wholesome Crossdresser]].
* Abigail "Ma" Hunkel was possibly the [[The Golden Age of Comic Books|first female superhero in comics history]] (and first superhero parody). A [[Brawn Hilda]] and [[Cool Old Lady]], she posed as a male hero using a homemade costume and fought evildoers as [https://en.wikipedia.org/wiki/Ma_Hunkel the orginal Red Tornado.]

== [[Fan Works]] ==
* {{spoiler|Dodoria}} in ''[[Dragonball Z Abridged]]''. [[Brain Bleach|Much to Vegeta's horror and disgust]].

== [[Film]] ==
* Kevin in ''[[Up]]''. Russell initially thought Kevin was a male, but later revealed to be a female when she calls to her chicks. He ''still'' refers to Kevin as a he.
* From ''[[Final Fantasy: The Spirits Within]]'', before the soldiers take off their helmets:
{{quote|Hear that, Jane? [[Shout-Out|She thinks]] [[Alien (franchise)|you're a man]].
I think she's an idiot. }}
* ''[[Heavy Metal (animation)|Heavy Metal]]'': The title character of the last story, Taarna, is summoned by the city's elders to fight the horde of evil invaders. The elders don't use any gender-specific words when speaking of the last of the Taarakians whom they're summoning, and when Taarna does arrive, she flies into the city on a pterodactyl-like steed wearing a hooded robe. Only when she lands in the city and dismounts her steed does Taarna reveal her gender by removing her hood (and shortly thereafter, [[Fan Service|everything else]] to keep up the film's quota).
* Technically, the stitchpunks of ''[[9]]'' are asexual constructs. This trope is still invoked with 7, whose female voice isn't heard until after "she" has demonstrated "her" combat prowess.
* The Dragon turns out to be this in the original ''[[Shrek]]''.
** Kitty, in ''[[Puss in Boots]]''.
* In ''[[Batman: Mask of the Phantasm]]'', {{spoiler|the Phantasm}}.
* Demetra, from ''[[Spy Kids|Spy Kids 3D: Game Over]]'', wore a head-obscuring helmet during her stay with the gang that Juni joins. (While there was slightly bulky armor, I don't think it would've mattered much on that front, her being a preteen at the time.) [[Romance Arc]]? Check.
* Maid Marian's initial appearance in ''[[Robin Hood: Prince of Thieves]]'', followed shortly after by [[Chickification]].
* From ''[[Sky High]]'', power-armoured supervillain Royal Pain turned out to be {{spoiler|Gwen, the girl that Will had a crush on. The weapon she built before being defeated by Will's superhero parents turned her into a baby, and her henchman raised her.}}
* In ''[[Return of the Jedi]]'':
** Boushh is {{spoiler|Leia}}.
** Rumored to have been the case for Boba Fett for a while, which would have put quite a different spin on the scene at Jabba's palace, where Boba makes a pass at one of the dancer girls. It's hinted at in a young reader book, and in fact his appearance in that book was later retconned to have been his daughter impersonating him.
* This seemed to be the idea behind Nyssa's first scene in ''[[Blade]] 2''. It didn't quite work. In fact, it would probably count as a genuinely surprising subversion of this trope if an armored antagonist were to wordlessly, facelessly appear, go toe-to-toe with the male protagonist using acrobatic moves, and then be revealed to ''not'' be female.
* ''[http://www.imdb.com/title/tt0082622/ Knightriders]'', Sir Rocky.
* ''[[Thunderball]]''. A motorcyclist kills a man driving a car (who's chasing [[James Bond]]) and rides away. After running the cycle into a ditch, the cyclist takes off the helmet and reveals that she's SPECTRE assassin Fiona Volpe.
* In ''[http://www.imdb.com/title/tt0082288/ Dragonslayer]'' (1981) a character turns out to be {{spoiler|a girl masquerading as a boy since girls are in danger of being sacrificed to the dragon.}}
* ''[[Hackers]]'': Neither Dade nor the audience know that Dade's rival, Acid Burn, is actually his love interest, Kate Libby, until a hacker lets that information slip about halfway through the film. Dade's fellow hackers do know who Acid Burn is, but when Dade initially assumes Acid Burn is male--"Do you know who he is?"—they gladly let him go right on thinking that--"No, I don't know who he is".
** From Lord Nikon's point of view, this is the case with Zero Cool, Dade's hacker alias when he was a kid (and responsible for one of the worst cyber-attacks in history). Being black, Nikon naturally assumed so was Dade.
* [[Barbarella]] in the beginning of the original film, where a bulky spacesuit is removed, and [[Fan Service]] ensues.
* Trinity in ''[[The Matrix]]'', from Neo's point of view; he'd heard of Trinity in Cyberspace [[There Are No Girls on the Internet|but assumed it to be a guy.]] Trinity replies that "most guys do."
* ''[[Terminator]] Salvation'': a jet pilot, who takes down a flying robot, and who ejects after an engine is shot by the machines which later causes an explosion, is only called "Williams". Marcus goes saving Williams, who is hanging from a telephone tower. Pilot takes helmet off, turns out to be a woman, Blair Williams.
* Racecar driver A.J. Ferguson in the feature film version of ''[[The Little Rascals]]'' turns out in the end to be...{{spoiler|1=Reba McEntire}}, shocking all the young male members of The [[He-Man Woman Hater|He-Man-Woman-Haters]] club.
* ''[[In The Son Of Robin Hood]]'' Little John has a problem with Robin's heir. Three guesses to what it is.
* ''[[The Sting]]'' has one {{spoiler|The hitman "Salino" turns out to be ''Loretta'' Salino, the waitress in the diner.}}
* A shocking variant was used in ''[[Hellbound Hellraiser II]]'', in which the gruesome Cenobites are involuntarily transformed back to their original human guises by the Lament Configuration. One Cenobite whose facial features had been burned away, leaving nothing but scar tissue and chattering teeth, is revealed to be {{spoiler|a young boy}}.
* Subverted in ''[[What's Up, Tiger Lily?]]'', a Japanese spy movie with new dialog by [[Woody Allen]]. An escaped prisoner in a head-covering scarf hops into the hero's car and drives off, then pulls off the headgear, revealing herself as a sexy girl. The hero reacts in surprise: "(whistle)... an Oriental!"
* In ''[[Pitch Black]]'', {{spoiler|the teenage boy "Jack" is revealed by Riddick, at a conveniently inappropriate moment, to be female. It turns out the blind creatures hunting them are tracing them by their scent of blood, and, although no members of the party appear to be wounded, "Jack" is menstruating.}}
* ''[[Pocket Ninjas]]'' when the White Dragon at the fight scene near the end was revealed to be Tanya.
* Subverted in ''[[Alien (franchise)|Aliens]]''. Male Marine to [[Action Girl]] Vasquez, as Vasquez does pullups in the locker room: "Hey Vasquez, you ever been mistaken for a man?" Vasquez: "No. Have you?"
* In the film ''[[The Last Legion]]'', familiarity with those trope allows one to quickly surmise that {{spoiler|the Eastern Roman Empire soldier is a chick.}} Why else would she wear a helm with an aventail like that?
* The opening scene of ''[[Iron Man (film)|Iron Man]]'' has Tony exclaim in suprise when he realizes that one of his three (military) escorts is actually female. She's revealed by her feminine voice the first time she speaks up.
{{quote|'''Tony:''' Good God, you're a woman!}}
* Quorra's introduction in ''[[Tron: Legacy]]'' has elements of this, as she wears a motorcycle helmet the whole time and even uses a voice modulator. Averted in that it's pretty clear from her outfit that she's a woman, and that the helmet and modulator are intended to hide her identity rather than her gender.
* In ''[[Indiana Jones and the Last Crusade]]'', Indy and Marcus Brody are a bit surprised to see their contact is, in fact, Dr. ''Elsa'' Schneider.
*  {{spoiler|The Blank / Breathless Mahoney}} in ''[[Dick Tracy (film)|Dick Tracy]]''. [[The Reveal]] is actually quite a [[Tear Jerker]].
* In [[Slasher Film]]s featuring female killers, the villain's gender is usually hidden by either a disguise, camera angles, [[Murderer POV]], or some combination of the three. Plus, they're probably played by random stuntpeople up until [[The Reveal]].
* In ''[[Stick It]]'', the hero in the introduction is apparently a cool dude who rides BMX and does crazy tricks. It's only after "he" starts running from the police that "he" sheds his big hoodie to reveal Haley, the female protagonist.
* In ''[[Sky Captain and The World of Tomorrow]]'', Polly reacts poorly when she meets Sky Captain's old mate, a [[Airborne Aircraft Carrier|carrier]] captain named Franky. In turns out that Franky's birth name is Francesca. And that Franky is [[Angelina Jolie]] wearing a kickass uniform and an [[Eyepatch of Power]].
* In the [[Vincent Price]] film ''[[Theatre of Blood]]'' Lionheart's lead henchman the British accented guy with the hippie glases, afro, and beard turns out to be his daughter Edwina (Dianna Rigg).
* In ''[[I Am Legend]]'' Will Smith refers to his dog as "Sam", until just before he has to put it down, when he addresses it as "Samantha". The movie treats this entirely meaningless un-plot-point as a major case of this trope.
** [[Rule of Cautious Editing Judgment|Or maybe]] [[Your Mileage May Vary|it doesn't...]]
* In ''[[Your Highness]]'', the heroes meet a mighty warrior in the arena, and are surprised when she removes her cloak.
* Many fans of the original ''[[The Texas Chainsaw Massacre]]'' believe this may have been true of Leatherhead, the killer. Why? Well, aside from the fact that Leatherhead never removed the mask - and in one infamous deleted scene, applied a victim's blood to the mask the way one would apply lipstick - his hobbies included cooking and interior decorating, two traditional female roles. Even if he did use rather... [[I'm a Humanitarian| unorthodox materials]] [[Human Resources| for both.]] True, this is an unfair stereotype, but then, [[Fair for Its Day| the movie was made in 1974.]]
*In ''[[Black Widow (2021 film)|Black Widow]]'', {{spoiler|Taskmaster's silence and all-covering helmet and clothing hide the fact that it is actually a woman rather than a man as per the comics, and not just any woman, but Dreykov's [[Not Quite Dead]] daughter Antonia.}}

== [[Literature]] ==
* Britomart in ''[[The Faerie Queene]]'' has three distinct "Bobs": The reader learns she is a woman after she defeats Guyon, but the first character to learn she is a woman is the Redcrosse Knight, after she saves him from a gang of six other knights. Her love interest is Artegall -- [[Love At First Sight]] for her, [[Love At First Punch]] for him.
** Bradamante in ''[[Orlando Furioso]]'', of whom Britomart is an [[Expy]], does this as well in the... unusual tale of her and Princess Fiordispina.
* In one of the cleverest examples of this trope, Joanne Harris' ''Gentlemen and Players'' has the {{spoiler|narrator}}. This is revealed close to the end of the book.
* {{spoiler|Jack}} in [[Robert A. Heinlein]]'s ''[[Tunnel in the Sky]]''.
* Aravis in [[Narnia|The Horse and his Boy]]—Shasta''/''{{spoiler|Cor}} is her "Bob".
* This happens in one of the ''[[Flashman]]'' novels, where he and a rebel against the Russian empire are rescued from prison by a group which includes a woman whose face is veiled. He is at first offput when she kisses him, knowing the cultural tradition of male bonding among warriors, but then relaxes when he notices her female attributes.
* Sir George, the knight who saves Princess Andromeda from a dragon in one of [[Mercedes Lackey]]'s ''Tales of the Five Hundred Kingdoms'', is actually Georgina. {{spoiler|And the dragon wasn't going to eat Andie anyway.}}
* Andre de la Croix in the ''[[Time Wars]]'' series. Also a [[Sweet Polly Oliver]], but the reader doesn't find out until after she's kicked serious butt at a tournament.
* In [[Esther Friesner]]'s ''Majyk'' trilogy, at one point the hero is rescued by a masked swashbuckler who identifies himself only as "a blade for justice." This eventually turns out to be {{spoiler|the hero's wife, disgruntled at being left at home while he's out on an adventure}}. Even after [[The Reveal]], she [[Sweet Polly Oliver|keeps up the masquerade]], finding swashbuckling to be a rewarding career.
* Eowyn from ''[[The Lord of the Rings]]''. She does appear previously in the story, but when she disguises herself as a man she's introduced and referred to as a new male character, until she reveals herself. A [[Genre Savvy]] reader will likely have already identified her by that point, though.
** In the book, anyway. In the movie she never introduces herself as the male character and nobody's fooled by the disguise; the director's commentary has Peter Jackson stating that they deviated from the book in that regard because they had to - it was simply impossible to make it convincing and they didn't want to insult the viewers' intelligence with a [[Paper-Thin Disguise]].
* In ''[[A Song of Ice and Fire]]'', Catelyn watches Brienne of Tarth win a tournament and assumes she's a man because she's encased in plate armor. Because Brienne is hulking, ugly, [[Pettanko|flat-chested]], and often wears warrior garb, she admits to being frequently taken for a man.
* ''[[Discworld]]'':
** Terry Pratchett's ''[[Sourcery]]'', {{spoiler|the mysterious thief turns out to be Conina, the daughter of Cohen the Barbarian}}
*** Although in this case, it's less a matter of bulky clothes, the book simply avoids gender specific pronouns at the start.
** Also ''[[Monstrous Regiment]]''.  {{spoiler|Everyone}} in the regiment is revealed to be a girl/woman.
** Lest we forget, the  {{spoiler|noble dragon}} in ''[[Guards! Guards!]]'' is one, too.
** In ''[[Feet of Clay (novel)|Feet of Clay]]'', it's revealed that  {{spoiler|Cheery Littlebottom}} is a female dwarf to the reader fairly quickly. As a lampoon on [[Our Dwarves Are All the Same]], Dwarven culture is <s>so male-centric that females typically behave and masquerade as men</s> stated that all dwarves are considered dwarves without distinction of sex. This can cause confusion when two dwarves like each other and need to delicately find out if they have met a friend or a mate. Angua detects her secret and coaches her to slowly adopt feminine behavior, which causes a lot of confusion among her other co-workers. She ultimately comes out of the closet and  {{spoiler|renames herself Cherry.}} She also starts wearing dresses. Chainmail ones with an axe... she said she was ''female'', she never said she wasn't a ''dwarf.''
** Subverted earlier in the series as well. When Angua is introduced in ''[[Men at Arms]]'' (''But she's a w...''), it is [[Most Common Superpower|obvious right away that she is female]], but it's not until later that the reader finds out that she is a werewolf, and some of the characters don't find out until the end.
* [[Tamora Pierce]] plays with this trope a bit. The readers know very well that Alanna/Kel is a girl (especially [[Sweet Polly Oliver|Alanna]]); it's the various characters who get the shock.
* Matt Ruff's ''[[Set This House in Order]]'' when we find out {{spoiler|that despite the personalities of the first person narrator being predominantly male, the body is female}}.
* P. Berling's "Die Ketzerin" ("The Heretic") begins with a knight tournament, and the winner is a woman, namely the main heroine.
* {{spoiler|Joat ("Jack-of-all-Trades")}} in ''[[The Ship Who...|The City Who Fought]]''.
* {{spoiler|The mysterious armored warrior}} in Grace Chetwin's YA series, ''Gom Gobblechuck''.
* [[Erast Fandorin]]'s {{spoiler|[[Arch Nemesis]] [[Diabolical Mastermind|Dr. Lind]]}} is revealed to be a girl in the final showdown, who kept her tightly-knit gang together ''with [[The Power of Love]]''.
* In the ''[[Conan]]'' story {{spoiler|''The Flame Knife''}} Conan is forced to leave a battle because of additional forces coming in for their own reasons. While trying to work out how to extract the girl who was hiding in a building the far side of the battlefield, one of his soldiers tells him it's taken care of and takes off "his" helmet.
* Crackers, George and Harold's pet pterodactyl in some of the ''[[Captain Underpants]]'' books, likely falls into this. After being hypnotised (along with Sulu the bionic hamster) into being evil, Crackers in fact does good. It was previously established that the doohickey that does the hypnotising causes females to do the opposite of whatever they are commanded to do. Plus, all of the pronouns relating to Crackers are highlighted-a fact which George and Harold notice.
* ''[[Harry Potter (novel)|Harry Potter]]'': Norbert the Norwegian Ridgeback is revealed to be female by the series' end. In light of this, her name was changed to Norberta.
* Director Inoue Sato in [[Dan Brown]]'s ''[[The Lost Symbol]]''. No awesome armor, but a surgically raspy voice and a cell phone connection do the trick.
* {{spoiler|Maugin}} in ''[[The Edge Chronicles]]''.
* ''[[From Russia with Love]]'': [[Ian Fleming]] goes into detail describing the hideous appearance of [[Dirty Communist]] Rosa Klebb, before ending with the words "She pulled up her skirt and sat down".
* Kitai from the ''[[Codex Alera]]'' gets this ''twice''. From the same person. You'd think that what with [[Guile Hero|Tavi being as smart as he is]] he'd pick up on things like that.
* In Robert J. Sawyer's ''[[Calculating God]]'',  {{spoiler|the main character (and the reader), are surprised to learn that the alien he has been working with is female.}}
* In one of Akutagawa's short stories, "The Martyr", the young man who was adopted by the Catholic church had been assigned the name "Lorenzo". Later, "he" was excommunicated from the Catholic church because a girl accused "him" of fathering her child. After "he" had saved her child from a burning house and the mother revealed the truth about the child's paternity, Lorenzo was revealed to be a woman all along.
** Wasn't this based on a true story? I'm sure there was a saint who was raised a monk, kicked out for 'fathering a child', but never admitted she was female - they only found out when they went to bury her. I'm off to google to find out who this was...
*** [https://web.archive.org/web/20120313112853/http://maroniteinstitute.org/MARI/JMS/july00/Saint_Marina_The_Monk.htm Saint Marina the Monk]
* Lampshaded straightforwardly in John Nichol's novel ''Point of Impact'', in which Jane, a female member of aircrew, is advised, after stepping down from an aircraft, to remove her helmet and shake out a mane of blonde hair - and she does. Nichol is an ex Tornado navigator famous for failing to set up an aircraft correctly on the final run into an Iraqi airbase in January 1991; understandable mistake, but not really the time to make it since the blunder earned him and his pilot a multi-week stay at the pleasure of the Iraqi regime and their baseball bats. Ironically, Nichol probably left the RAF around the time female fast-jet aircrew began to appear.
* In Patricia Briggs' ''When Demons Walk'', Sham is often mistaken for a pubescent boy, a resemblance she augments with masculine dress and hair. Kerim has an entire conversation with "him", Talbot watches "his" interrogation, and when Kerim is attacked Sham throws the knife that kills the attacker. When they try to find him again, they can't figure out how he managed to disappear so completely, until an amused informant finally reveals that they should start asking about local ''women''.
* At a Worldcon panel, an anecdote about an accidental, out-of-story example from ''[[The Hunger Games]]'' was discussed: The author, Suzanne Collins, works as a teacher, and at one point a boy in her class, who was most of the way through the first book, gushed about Katniss to her, saying "He's so cool!". Collins pointed out that Katniss was a girl, to which the boy responded, [[Stay in the Kitchen|"Girls don't hunt!"]]
* This is the [[Twist Ending]] of ''The Turbulent Term of Tyke Tiler'' by Gene Kemp.  {{spoiler|Throughout the book, [[Naughty Is Good|goodhearted troublemaker]] Tyke has been the narrator, so [[The All-Concealing "I"|we don't get any gender-specific pronouns]] and only occasional references to "[[Embarrassing First Name|my real name]], [[Do Not Call Me "Paul"|the one I hated]]". It's only at the end, when Tyke climbs the roof of the school in imitation of possible ancestor Tom Tiler, that we hear a teacher screaming "Theodora Tiler, you naughty, disobedient girl!"}}
* In ''[[Star Wars: The Old Republic]]: Fatal Alliance'', Dao Stryver is a tall, tough [[Proud Warrior Race Guy|Mandalorian]] wearing full body armor and helmet. The novel consistently refers to Stryver as "he." He has a deep, male voice, filtered through his armor. At the end, Stryver turns out to be a [[Lizard Folk|Gektl]] female, although one character knew it all along. Since most Mandalorians shown in films and games tend to be male humans, this was a big shock. This is even more jarring in the audiobook, where the narrator makes an effort to make Stryver to sound like a tough guy, using special effects to add to the feel of the character. Then comes the Gektl female with [[Sssssnaketalk]].
* In the [[Ciaphas Cain]] novel ''Duty Calls'', Cain is saved by a warrior in [[Powered Armour]] who turns out to be Amberley Vail. It's not her first appearance, but the unidentified warrior is separately established under that description before the reveal.
* In [[Iain M Banks]]' ''[[The Wasp Factory]]'',  {{spoiler|the ''protagonist himself'' only finds out at the end that he is physically female. He was attacked by a dog in childhood, and his father claimed that the dog had castrated him. His father fed him male hormones in the meals.}}
* In the first in the ''[[A to Z Mysteries]]'' series ("The Absent Author"), our detectives try to get reclusive mystery author Wallis Wallace to show up. Wallis doesn't show up, but the gang finds him kidnapped...  {{spoiler|then realizes Wallis is really tourist Mavis Green, and the kidnapped man is her brother, Walker.}}
* [[Jirel of Joiry]] is revealed this way in her first story "Black God's Kiss".
* In [[James Herbert]]'s ''Nobody True'', the ghost protagonist spends a lot of time stalking a hideously deformed serial killer with psychic powers named Alex, and even ends up possessing the killer's dead body to use it to save his family...only to find that Alex was short for Alexandra, and she was too deformed to notice her breasts. Alex even walked like a man.
* In ''[[Firebird Trilogy|Firebird]]'', Brennen Caldwell initially assumes Firebird Angelo is a man, simply because she was a pilot in the attack phalanx of the Netaian invasion force. His assumption is corrected after she is captured.
* In ''[[Alan Dean Foster|Icerigger]]'', it's not revealed that  {{spoiler|Sagyanak the Death}} is female until well after the Horde has been driven from Sofold.
* Boba Fett's estranged daughter Ailyn Vel impersonated her father for a period of time. So deadly and ruthless was she that everyone who met her during this period thought she really was her father—but her utter lack of ethics went beyond even Fett's harsh methods, and years later the truth was eventually discovered.
* In the ''[[Black Company]]'' novels, Soulcatcher, one of [[Quirky Miniboss Squad|the Ten Who Were Taken]] is an interesting example. It's well known that three of the Taken are female, but owing to the Taken's habits of concealing their true features, no one's quite sure which and just call them all "he" indescriminately. Soulcatcher herself further confuses matters by the fact that her voice changes continually to reflect the souls she's stolen, so her voice is sometimes male, sometimes female. However, it ''is'' noted that Catcher's masculine clothing doesn't fully conceal her shape and "he" has fairly effeminte mannerisms- at the end of the first book, Catcher's ubiquitous helmet comes off and she's revealed to actually be a woman. Later in the series she makes no attempt to disguise her gender, even when hiding her face.
* Leigh Brackett wrote several [[Planetary Romance]] tales of a Mars resembling that of [[Edgar Rice Burroughs]], but also suffering colonialism from Earth. One of these stories brings protagonist Eric John Stark (a [[Darker and Edgier]] [[Tarzan]] [[Expy]]) into conflict with Lord Ciaran, a warlord who never takes off his [[The Faceless|face-hiding helmet]] in public. When Stark finally rips Ciaran's helmet off in battle, what's underneath is "a splendid face, but never on any of the nine worlds of the sun could it have been the face of a man." (This was originally published under the title "Black Amazon of Mars," telling readers Ciaran's secret before the first page; "black" here refers to the color of her armor.) The tribesmen she'd led are faced with an unspoken choice: they can either kill her for deceiving them, or worship her as a warrior goddess. {{Spoiler|They start chanting her name as a battle cry, and Stark realizes he's just made Ciaran even more powerful.}}

== [[Live-Action TV]] ==
* Vala in ''[[Stargate SG-1]]''. Downright hilarious when she starts trying to seduce Daniel while wearing the armor of an artificially engineered monster super-soldier, and with her voice masked to match... A bit of a variation in that ''Vala'' was the one who attacked the ship and captured Daniel.
** Also, in the pilot episode of ''[[Stargate SG-1]]'' General Hammond mentions that he has assigned Captain Sam Carter, their top Stargate expert, to Colonel O'Neill's team. Col. O'Neill asks where he is transferring from. From the door, Captain Carter tells him that ''she'' is transferring from the Pentagon.
* Similarly Aeryn Sun of ''[[Farscape]]'' (also played by Claudia Black, incidentally) is first seen as a fearsome person in a bulky, black, armored spacesuit with a smoked-glass helmet, on a spaceship full of bizarre alien creatures. Off comes the helmet...and you see a fearsome, angry (but attractive) woman in an armored spacesuit.
** While no helmet or concealment is involved, in the episode "The Flax" one very masculine-looking Zenetan pirate (played by a male actor) is revealed to be female of her species by the end of one Farscape episode. In their race, both genders look androgynous, and a female can pass as male.
* In ''[[Kamen Rider Faiz]]'', Kamen Rider Delta was revealed to be a woman encountered by the cast previously (until then, we'd also never seen Delta in real action; just baddies getting wasted and Delta standing there). In an example even worse than the Zelda one, she's just about to suit up for the first time since we found out who she was and have her first onscreen fight scene... when she's ''impaled'' by a villain and her armor taken and used by another. (The ''[[Kamen Rider]]'' franchise, either because of tradition or [[Values Dissonance|extreme and utterly shameless sexism]]—hopefully, the former—has had exclusively male heroes since [[Kamen Rider (TV series)|it began in the 1970s]], with the rare exceptions eventually being [[Women in Refrigerators|executed by the plot]] for their audacity. Nobody savvy about the franchise expected her to survive long, though getting to see her in action once would've been nice.)
** Well they did have ''another'' female transform into Delta. For about five seconds... then she gets hit once and de-transforms. Japan just changes very slowly,simple as that.
*** Ironically (and probably even more sexist), the Riders who we know are women from day 1, or who are evil, don't last long either, but they do last longer than any and all cases of Samus Is a Girl.
** In ''[[Kamen Rider Fourze]]'', {{spoiler|1=the Scorpio Zodiarts is revealed to be female, despite having a male voice and fake hints being dropped that various male characters were Scorpio. However, Japanese-speakers may have noticed the [[Significant Anagram]]: Sarina Sonoda = Sasori na no da = "I am the scorpion."}}
* No mortal peril involved (and probably no relationship, but this is MacGyver we're talking about), but a female T-38 pilot does this on an episode of ''[[MacGyver]]'' after she gives Mac a free flight. Get your minds out of the gutter...
* The opening of the ''[[Witchblade (TV series)|Witchblade]]'' TV show had a figure going about his day - putting on his boxer shorts, putting on his leather jacket, and getting on his motorbike, before 'he' takes off his motorcycle helmet and it's a woman.
** Doesn't help that there's such thing as women's boxers.
* In [[TNA]] Wrestling, the Latin American Xchange was often helped in their matches against the Rock 'n Rave Infection by a mysterious latino in baggy gangsta attire with a bandana covering "his" face. Said mystery "man" often attacked the Infection's valet, Christy Hemme, prompting her to repeatedly complain to on-air authority figure Jim Cornette about the "man-on-woman violence" going on. Of course, the mystery member of LAX later revealed herself as a latina named Salinas, thus making the Rock 'n Rave Infection look like a bunch of whiners. And immediately after [[The Reveal]], her attire went from concealing to [[Stripperiffic]]. Hey, it is [[Professional Wrestling]] after all.
* The 2006 series of ''[[Robin Hood (TV series)|Robin Hood]]'' tries to pull this off with the identity of the Night Watchman, but doesn't quite manage it.
** It also does something similar with Djaq- the first confirmation the astute audience get of her gender is Will walking in on her naked (ritual cleansing pre-prayer in fact). {{spoiler|Considering later events, it makes it a [[Naked First Impression|naked second impression]] as the two become canon.}}
* In one episode of Chris Titus', um, ''[[Titus]]'', his girlfriend's niece and ward Amy is distraught over her breakup with "Charlie." After an episode-long flashback to the title character's high school days, Titus' girlfriend shows "Charlie" in. It's a girl.
{{quote|'''Titus''':(smiling confusedly) Ch-Charlie. That's one of those trick names. So that means...
'''Amy''': -I'm a big fat [[N-Word Privileges|dyke]]? ''Yeah.'' }}
* ''[[Power Rangers SPD]]'': {{spoiler|the Red Ranger of the SPD A-Squad}}. Double points for {{spoiler|having the [[Tomboyish Name]] Charlie}}. This actually caused a bit of a stir on the Rangerboard forum: one member, being an expert in digital voice manipulation, {{spoiler|guessed -- and posted -- that he thought A-Squad Red was a girl. Then comes the reveal, and he was not. Modest. At. All. He ended up printing a t-shirt of Charlie that said "I was right!" and got several SPD cast and crew members to sign it.}} [[Crowning Moment of Awesome]]?
** They ''tried'' pulling this off again in ''[[Power Rangers RPM|RPM]]'' with Dr. K (key word being ''tried''), but it failed for two big reasons: One, the voice distortion she used still sounded too feminine, and two, a trailer that got leaked showed a girl with the label ''Dr. K''. And even then, this isn't getting a spoiler tag due to the fact that the reveal happened in episode 4!
** It's also done in ''[[Power Rangers Ninja Storm]]'', in the second part of the episode "The Samurai's Journey", with Cam's mother Miko.
* ''[[Kyle XY]]'': {{spoiler|1=AndyJ}}.
* From the ''[[Bones]]'' episode "Fire in the Ice", Albie the poker ring organizer. Booth is very shocked. Perhaps because he [[Hey, It's That Guy!|recognizes her]] from his ''[[Buffy]]'' days?
* Subverted in the first episode of ''[[Get Smart]]''. We can tell Agent 99 is a girl, it just takes Max a while to realize it.
** A funnier one occurs in a later episode where Max agrees to host a scientist who has the power of invisibility at his house while 99 (now married to him) is on vacation. He then finds out after the scientist becomes visible that the scientist is female (and even the Chief didn't know!). Now he must deal with hosting a female while his wife is out (think about how that would look to others). It gets worse when 99 comes back from her trip early and accuses him of cheating when she finds him; thankfully they sort it out.
* A textbook example, from a second season episode of ''[[Merlin (TV series)|Merlin]]'', we see {{spoiler|a sorceress, played by Emilia Fox, being all sorceress-y. We then see someone in a full suit of armour waltz through Camelot, kill five guards, enter the Great Hall, challenge Arthur to a duel, ''then'' remove her helmet, shake out her long blonde hair and reveal... Emilia Fox}}.
** In fairness, there was a pretty good hint - {{spoiler|Emilia Fox is only 5'2". That is one dinky knight.}}
* ''[[Doctor Who]]'':
** "[[Doctor Who/Recap/S25/E01 Remembrance of the Daleks|Remembrance of the Daleks]]": {{spoiler|The Renegade Dalek battle computer is the young girl constantly seen beforehand.}} Made more effective by having a voice of the opposite gender before [[The Reveal]].
** "[[Doctor Who/Recap/S32/E01 The Impossible Astronaut|The Impossible Astronaut]]": {{spoiler|The eponymous astronaut is the little girl who is constantly phoning [[Richard Nixon]] for help.}}
** "[[Doctor Who/Recap/S3/E04 The Daleks Master Plan|The Daleks' Master Plan]]": Mavic Chen and his aide decide to call out their toughest Space Security Agent to apprehend the Doctor and company. It takes several scenes before we establish that "Kingdom"'s full name is "Sara Kingdom."
* In the less than impressive sequel to the Sam Neil version of ''[[Merlin (TV miniseries)|Merlin]]'', ''Merlin's Apprentice'' Squire Brian turns out to be Squire Brianna.
* ''[[Blackadder]]'': "I always thought that Jamie and Angus were such fine boys." "Angus is a girl."
** The ''Blackadder the Third'' episode "Amy and Amiability" has a subplot involving a mysterious highwayman called "The Shadow". It turns out to be Amy Hardwood, a woman he had earlier tried to fix the Prince Regent up with.
* ''[[Homicide: Life on the Street]]'': Lewis' first reaction to Det. Teri Stivers in Season 5 is reminiscent of this.
{{quote|'''Lewis:''' Which one of you is Stivers, I'mma slap you.
'''Stivers:''' I'd like to see you try, pal! }}
* In the pilot episode of ''[[Las Vegas]]'', Danny looked all over town trying to find the mysterious casino host, Sam. He only found out Sam was female after she'd already pumped him for information, posing as her own secretary.
* In the fourth season of ''[[Solitary]]'', Number 3 was in their early twenties, and an ex-high school football player. And she was a girl. While the viewer knew from the start she was female, all the other numbers thought she was a boy. Number 3 eventually made it to the final three (and eventually won), which is when the other two finalist (2 and 6) found out she was a girl. They were a bit surprised.
* Season 2 of ''[[Warehouse 13]]'' features {{spoiler|[[H. G. Wells|Helena G. Wells]]}}.
* In ''[[Psych]]'',  {{spoiler|the terrifying [[Serial Killer]] Mr. Yang}} is revealed to be  {{spoiler|played by Ally Sheedy}}. The surprise of the Reveal is slightly more justified than most cases of this trope, in the defense of the main characters, what with her  {{spoiler|very clearly presenting herself in her letter as MISTER Yang, not just Yang or anything gender-ambiguous. Who says [[Villains Never Lie]]?}}
* In the first scene of the pilot of ''[[Lois and Clark]]'' a young man with a mustache and beard enters the Daily Planet. He sits down at a desk, then removes the disguise to reveal that he is actually Lois Lane, who was working on an undercover story. Lois also cross-dresses in a season 2 episode, where neither her boss nor Clark recognize her immediately.
* Ziggy Vadas from ''[[Life]]''.
* ''[[Community]]'': Greendale's Human Being mascot is revealed to be portrayed by a female student during a webisode.
* In ''[[Castle]]'', {{spoiler|Lone Vengeance}} is revealed to be a previously unsuspected woman.
* In the first ''[[Hercules: The Legendary Journeys]]'' episode/pilot movie, much suspense is made of the nature of the "beasts" and the eventual dramatic reveal that they are, in fact, women. This would be much more dramatic if the episode weren't called ''[[Spoiler Title|Hercules and the Amazon Women]]''.

== [[Manhwa]] ==
* [[Witch Hunter]] pulls this card with  {{spoiler|Halloween, Tasha's pumpkin-headed marionette}} who is initially thought to be genderless due to  {{spoiler|being a marionette}} and all that, but when  {{spoiler|Tasha}} breaks  {{spoiler|Halloween's}}first seal, it's true form is revealed to be [http://download.minitokyo.net/Witch.Hunter.477596.jpg this.] Tasha is, naturally, shocked.

== [[Music]] ==
* The music video for Prodigy's "Smack My Bitch Up". The reveal is at the end when the camera (from a first-person perspective) looks at a mirror. Before this she went to a bar, got drunk, beat up patrons and groped hot girls before returning home and passing out in front of a mirror.
** A similar "woman doing manly things only revealed to be a woman at the end" music video is Bush's "Machinehead".
* Turkey actually used this in their performance in the Eurovision Song Contest 2010, "We Could Be the Same" by maNga. [http://www.youtube.com/watch?v=XjULJg4Ce6M Watch it here.]
** They must not have been trying that hard, because one good look at the figure makes it really obvious what her gender is.
* The trance artist formerly known as Hybrid Factor was originally [[The Invisible Band|pictured as]] Steve Bailey, but later revealed to be Aimee, his sister. She now goes bt the artist name Aimee B.
* Many promotional videos of the British Invasion band The Honeycombs attempted to hide the fact that their drummer, Honey Lantree, was female until some point later in the film clip (most notable is their performance of "Have I The Right?" in the 1965 concert film ''[[wikipedia:Pop Gear|Pop Gear]]''. They then do the ''[[Viewers Are Goldfish|same damn thing]]'' the next time they appear in the film, performing "Eyes")

== [[Newspaper Comics]] ==
* In ''[[Funky Winkerbean]]'', The Eliminator was a [[Enfante Terrible]] arcade gamer of such skill, he could make a Defender machine tilt like a pinball game. His face was always covered by a visored helmet (a [[Shout-Out]] to Darth Vader, as ''[[The Empire Strikes Back]]'' was THE hot movie at the time of his debut). Midway through the first [[Time Skip]], the grown-up Eliminator was reintroduced... as Donna, a hot blond woman. She eventually ended up dating and marrying Crazy Harry, who'd considered The Eliminator his nemesis back in high school.
* In ''[[Mother Goose and Grimm]]'', Grimm was shocked to learn that his hero, the star of the TV show ''Karl the Wonder Poodle'', was a female poodle named Karla.

== [[Tabletop Games]] ==
* ''[[Ravenloft]]'' had a series of supplements called the Gazetteers, which featured a scholar known as S who traveled around the major domains of the setting and chronicled their cultures. Everyone assumed S was a man until Gazetteer III, which featured a throwaway line about S's struggles to manage the layers of corsets, skirts, and petticoats that one domain expected its citizens to wear. Even then, some fans continued to insist that S was a man (apparently more willing to believe the character to be a drag queen than a woman), and it wasn't until an actual illustration of her appeared in Gazetteer IV that the argument was put to rest.

== [[Video Games]] ==
* Obviously, Samus Aran herself from ''[[Metroid]]''. Eventually subverted as, over the course of the series, developers have gone further and further out of their way to point out that she's a girl.
** Zero Suit? Seriously, ''Other M''? Did Adam not authorize clothes or something?
** Also important to note that Samus was always female and that this wasn't a retcon; the original design team decided that she should be, because why not?
*** The localization team for the first game did, however, imply in the manual that Samus was male.
* Ivysaur from ''[[Super Smash Bros.|Brawl]]'' was obviously female in the Japanese version, but apparently the English localization team didn't get the memo and gave her a masculine voice.
** Speaking of Pokémon, many Pokémon like Machoke, Machamp, the Conkeldurr line, Kadabra, Alakazam and Emboar look manly, but have a 25% chance of being female (12.5% in Emboar's case).
* Zelda's disguise as the male Sheik in ''[[The Legend of Zelda: Ocarina of Time|The Legend of Zelda Ocarina of Time]]'', who was designed with a male character model to keep the disguise more convincing. Programmers admitted she didn't get a more realistic design until ''[[Super Smash Bros.|Super Smash Bros. Brawl]]''. Nevertheless, there's endless [[Fan Wank]] as to the nature of the disguise, especially since Zelda seems to have entirely different abilities, powers, and ''eyes'' than Sheik.
** It states right on her trophy in Melee that she uses magic to change her clothing as well as her skin and eye color.
*** For some time, there was a very popular fan theory which stated that Sheik IS male, and that Zelda not only changes appearance but also gender when she transforms. [[Word of God]] has since stated that this is not so; Zelda can't change her entire body like that, just a few surface details.
** Along with realistic design, Sheik became rather more obviously female in Brawl.
** It's even more obvious in the beta version, too obvious thus they changed her. Sheik had a somewhat more feminine haircut, looked more round (and thus female), and had blue eyes.
** And guess what? Sheik shows to be feminine, too (like she did in Brawl), in the 3DS remake. [[They Wasted a Perfectly Good Plot|Too bad she still didn't unmask herself]].
** And, as of Skyward Sword, guess who/what else is female? {{spoiler|The Master Sword. Technically [[The Legend of Zelda: Skyward Sword|the Skyward Sword]], but eventually our old friend.}}
* Syfa/Sypha from ''[[Castlevania]] III'' (only because a [[Blind Idiot Translation]] used the wrong pronouns).
** One particular guide writer is very bad about accepting this fact, and insists that Sypha is male. Never mind the ending if you finish with Sypha, which involves Trevor and ''her'' getting married. Never mind that this marriage led to Juste Belmont of ''Castlevania: Harmony of Dissonance'' being able to use magic. Never mind how you can fight clones of Sypha (as well as Trevor and Grant) in ''Symphony of the Night'' and ''Portrait of Ruin'', and Sypha's sprites show her in a revealing/flowing white robe with a very female voice.
** It's pretty clear that for whatever reason, you're not ''supposed'' to know that she's a she ''until'' you complete the game with her (and the "mistranslation" was deliberate). Y'know like, oh... Samus Aran?
*** Not to mention that the gameplay does not really try to hide the fact that Sypha is a woman; aside from seeing a largely feminine figure when she opens her cloak to cast spells, and her head shot at the top of the screen, she also makes a distinctly female-sounding grunt whenever she takes a hit.
*** Just to make sure the audience knows Sypha is a woman, in ''Judgment'' she has quite nice breasts, and her breasts are even a joke in Maria Renard's story. In addition, her ending confirms that she was [[Sweet Polly Oliver|deliberately posing as a man]] in ''Castlevania III''.
** [https://web.archive.org/web/20121023184619/http://images4.wikia.nocookie.net/__cb20090322080212/castlevania/images/b/b2/SoTN_Old_Axe_Armor.JPG Here] is the sprite for the playable Old Axe Armor from ''Castlevania: Portrait of Ruin''. [http://castlevania.wikia.com/wiki/File:Por_pic_41.jpg here] is an official piece of artwork of the same character.
* In ''[[Kid Icarus]]: Uprising'', it turns out  {{spoiler|''Dark Lord Gaol'' is one.}}
* This is the twist in Akira's ending in ''[[Rival Schools]]: United By Fate''. The introduction of the story mode introduces her as the younger brother of gang leader Daigo Kazama and refers to her as male. The masquerade is carried on throughout the story, and even in her [[Multiple Endings|"bad" ending]] - only when you achieve the "good" ending is Akira's true identity is revealed.
** Although it was kind of obvious to the players: she has a very feminine voice, and if I recall right one of her costumes has her without her helmet on, where you can clearly see she's a girl.
*** That's a bonus version of Akira which you unlock after beating the game with the good ending (notably, in the usual slide show during the credits, she is seen helmetless with her Gedo schoolmates, but if the player didn't get said good ending, they'll probably be left clueless, as in "who's that girl? where's Akira?"). Which is interestingly inverted in ''Project Justice'': she starts off helmetless (due to [[It Was His Sled]]), ''and'' her helmeted costume (labeled "Powered Akira") is the unlockable one.
* King in the first ''[[Art of Fighting]]'' game nearly pulls this off despite [[Bifauxnen|not wearing an actual disguise]]. By finishing her off with a special move in the last round, the player can [[Clothing Damage|blow her shirt open and expose her bra.]] Supposedly, she was hiding her gender because, at the time, guys were [[Wouldn't Hit a Girl|too hesitant to fight her]], at least without holding their blows. In the second game and ''[[The King of Fighters]]'' series, King's true gender [[It Was His Sled|is an already known fact]], and since then, she's become proud to be an [[Action Girl]], often leading [[Amazon Brigade|a whole team of them]].
* [[Pirate|Captain Syrup]] from the first ''[[Wario Land]]'' is a villainous example; the game's instruction manual even refers to her with masculine terms to avoid ruining the surprise.
** Although if you didn't read the manual, this one was pretty much lost on you, since she doesn't appear in-game until you fight her.
* Faris of ''[[Final Fantasy V]]''. Although she seems to pass for male strictly because [[Stupidity Is the Only Option|she says so]], as she's pretty enough for Bartz and Galuf (dueling Bobs) to swoon over her sleeping form, still thinking she's a he. This, of course, leads to Gilgamesh's classic line in the GBA Remake: "And now we will fight like men. And ladies. And ladies who dress like men."
** This is more a failed attempt at pulling a Samus Is a Girl due to their choice of Super Deformed graphics. Yoshitaka Amano's original designs for Faris depicts her in a very [[Bifauxnen|masculine, yet feminine fashion]].
*** On the other hand, pretty much all of Amano's original designs are kind of feminine.
*** The FMV for the remake follows Amano's design very closely, so it can't be completely attributed to Amano's artistic style. She could pass for a guy if it weren't for her coat being tight enough to clearly show she is female. On the other hand, outside her crew, virtually no one would get close enough for obscuring her figure to be required.
* This is the main twist in the ending of the iOS edition of ''[[Dead Space (video game)|Dead Space]]''.  {{spoiler|Vandal reveals her true identity to be Karrie Norton as she lies wounded on the floor near the defeated final boss.}}
* [http://www.rockpapershotgun.com/?p=1955 A developer's choice of words] during an interview has [[A Worldwide Punomenon|added more fuel to the fire]] on this trope being employed with the Pyro from ''[[Team Fortress 2]]''.
** Valve has seemingly been encouraging this from the beginning, with [http://www.teamfortress.com/images/posts/pyro_front.jpg this] trading card for the Pyro and the purse in the Pyro's locker. When one consider that the other 8 player classes (in other words, every character excluding the Announcer) are unambiguously men, it makes sense that they would play with [[The Unseen]].
*** Some say the Pyro has a flowery purse because he's just a [[A Worldwide Punomenon|flamer]].
** A check of the voice acting credits for the game reveals that Pyro's unintelligible ranting is voiced by [http://www.imdb.com/name/nm0060794/ Dennis Bateman], who is definitely male. Whether this is deliberate obfuscation or not will probably only be resolved when Valve gets around to releasing the "Meet The Pyro" video.
*** To add another level of confusion, Dennis Bateman also voices the very definitely male Spy.
* ''[[Final Fantasy Tactics A2]]'' plays with this in reverse. One of the recurring enemy characters is the Night Dancer, a Bangaa that looks, acts and is referred to as being a girl, but the fight against her has a Law in place forbidding harming the opposite sex, setting up a potential hazard for the player who does not understand the difference between gender and sex.
** Lampshaded by an NPC who is confused on what gender the Night Dancer is and another NPC refers to the character as an old man.
** Wouldn't be the first time. ''[[Final Fantasy Tactics]]'' had the infamous(?) cross-dressing Time Mage. Someone put a one where a zero should have gone, metaphorically speaking.
** In the original ''[[Final Fantasy Tactics]]'' {{spoiler|Saint Ajora may or may not count depending on your point of view.}}
* Toby Masuyo in ''[[Baraduke]]'' predates Samus by about a year (Although the fact that the game calls her "Kissy" is a bit of a giveaway). Her next appearances in the ''[[Mr. Driller]]'' series and ''[[Namco X Capcom]]'' do not play with this trope, opting to have her helmet-less (she's Mr. Driller's mom after all).
* Happens ''twice'' in ''[[Tales of Vesperia]]''. The first is with Yuri's pursuit of "Mr. Mordio"—which turns out to be a ''Rita'' Mordio; the second is with the mysterious (and kickass) [[Dragon Rider]]—which turns out to be {{spoiler|Judith}}. In both cases, Yuri winds up the "Bob". And in both cases, they remain a full-fledged mage and warrior, respectively.
** In his defense "Mr. Mordio" clearly has a mustache, and had to have been seen to do the job he was contracted with. It's just he was using someone else's name. Played straight when you reach Aspio and everyone refers to Mordio as "that person" or "that weirdo".
* The Cyborg Ninja in ''[[Metal Gear Solid]] 2'' is not Gray Fox as in the first game, but instead {{spoiler|Olga Gurlukovich.}}
** In a way, this happens {{spoiler|twice with the same character. When the player first encounters Olga in the tanker chapter, Snake is surprised that the Russian soldier on the deck turns out to be a woman.}}
* The last target in ''[[Assassin's Creed]]'' is not there when you go to kill him. {{spoiler|The person disguised as him is revealed to be a woman after [[Player Character|Altaïr]] defeats her in a swordfight. It's only somewhat given away in that when you hit her, her pained grunts are notably higher pitched than normal.}}
* The Power Armor in the ''[[Fallout]]'' series has always been gender neutral, but hearing a female voice from the Power Armor speakers in ''Fallout 3'' caused players Samus Is a Girl spit-takes (and demand from female players for more feminine and form-fitting Power Armor mods).
** Before then, ''most'' power-suited Enclave soldiers in ''Fallout 2'' were actually female. Even some that you spoke to.
* {{spoiler|Naoto Shirogane}} in ''[[Persona 4]]''. With the twist that the party finds out when they show up to rescue ''her'', rather than her rescuing them.
** Somewhat frustrating, as you can hear feminine tones from the moment you see her (in the American Version), but the game will force you to play along with it until {{spoiler|you face her dungeon}}. This can lead to [[Only Sane Man|the player screaming]].
*** Needless to say, the Japanese version is ''much'' more convincing, if only because her voice actress has done male roles before (she did [[Fullmetal Alchemist|Edward Elric]]).
** Also the case with {{spoiler|The gas station attendant/Izanami}}. This one is done quite a bit better, which makes it sort of puzzling why they didn't use her voice actress for {{spoiler|Naoto}}.
* ''[[Portal (series)|Portal]]'' plays with this, in that the [[Heroic Mime|main character]] is female, but there's no indication of this until you happen to get a good look at yourself through a portal. While you can clearly see yourself in the very first portal you step through, it's hard to tell that it's you right away. In the sequel, Wheatley passively assumes that whoever beat [[Master Computer|GLaDOS]] was a guy, and is taken aback when he finds out that it was ''you''.
* ''[[World of Warcraft]]'': In the Howling Fjord quest, "We Call Him Steelfeather", the player has to discover why Steelfeather - a hippogriff - has become so ornery and aggressive towards the soldiers at Fort Wildervar. The player eventually discovers that the reason is a next with hatchlings - [[Monster Is a Mommy| obviously, Steelfeather is a female and a mother.]]
* The first ''[[Destroy All Humans!]]'' revealed that Majestic-12 leader Sillouette is a female at the end, though you can learn this earlier on if you read the thoughts of a Magestic agent, which you might just ignore.
* ''[[Metal Gear Solid]]'' does this with Meryl, who "disguises" herself as a male soldier, though it's really only because [[Faceless Goons|all the uniforms look more or less exactly alike]].
* [[Word of God]] states that this was to have been the big reveal at the end of the fifth game in the old [[ZX Spectrum]] Magic Knight series (''Finders Keepers'', ''Spellbound'', ''Knight Tyme'', ''Stormbringer'' and...). Possibly [[Older Than the NES]], possibly not (the first two games both came out in 1985, and the first game definitely refers to Magic Knight as 'he', so it may not have been planned at that point).
* In the first ''[[Tekken]]'', Kunimitsu was simply a palette swap of Yoshimitsu, with the same voice as well. In the second game, the character was revealed to be female.
** Although it has to be said, she was always meant to be female, as you can see in concept art. 3D graphics weren't that good at the time of the first ''Tekken'', however.
** And there is also Leo from ''Tekken 6'', who is widely believed to be a woman dressed as a man, or a gay male. Namco have deliberately not confirmed either way, stating they wanted to create a character who could be "loved by either gender". {{spoiler|Confirmed to be female by [[Word of God]].}}
* In the game by Tim Schafer, ''[[Brutal Legend]]'', Eddie, the main character, fights many demonic druid enemies in robes, and then faces one of them head on. In the middle of the fight, that "evil druid" flips off her hood to reveal that this is, in fact, a female human. Eddie the remarks, "Oh no, don't tell me I've been slaying hot chicks this whole time."
* At the end of ''[[Dragon Warrior Monsters]]'', the {{spoiler|masked monster master at the Starry Night tournament is revealed to be Milayou, the protagonist's younger sister.}}
* Hooktail, the boss of the first level in ''[[Paper Mario: The Thousand-Year Door]]'', is assumed to be male by all characters (and described with male pronouns in Goombella's Tattle), until the final chapter, when you meet Gloomtail in the Palace of Shadow. When your partner asks what Hooktail is doing here when you've already beaten him (as Gloomtail is essentially a palette swap of Hooktail), Gloomtail becomes furious upon learning what you did to his precious baby ''sister''. Tattling on Gloomtail elicits a hilariously shocked reaction to this revelation from Goombella.
* The third ''[[Sly Cooper]]'' game gives us {{spoiler|the Black Baron, an ace fighter pilot whose face is entirely covered by his huge mustache. Only after you beat him do you learn that he's actually [[Gadgeteer Genius]] Penelope, who created the disguise to get around the dogfighting league's age restrictions.}}
* The mysterious scrambled voice in the marine campaign in ''Aliens vs. Predator 2'', though she never actually does any fighting.
* Black Widow from ''[[Saturday Night Slam Masters|Ring of Destruction: Slam Masters II]]'', is a somewhat effeminate wrestler who is taller than most of the other wrestlers in the game and whose spider-themed costume covers his whole body. If you beat the game with him, Widow reveals herself to be a [[Statuesque Stunner|tall]] and [[Amazonian Beauty|muscled]] female wrestler.
* Around half-way through ''[[Ratchet and Clank Going Commando]]'', the thief you have been pursuing is unmasked to reveal that she is female, to Ratchet's surprise. This also marks the point at which she stops being an enemy, but more because they were betrayed by the real villain.
* Junon from ''[[Dragon Force (video game)]]'' pulls this one on everyone in her world until her helmet gets knocked off during an encounter. [http://img525.imageshack.us/img525/7150/thedragonforcepe0.png She's the one in the badass black armor]. [http://img221.imageshack.us/img221/1096/gatheringtotallabelledwb5.png She's also #139].
* {{spoiler|The Great Mizuti}} from ''[[Baten Kaitos]]''.
* The video game series ''[[Guilty Gear]]'' is notorious for pulling off a reverse of SIAG (Bridget needs no introduction), but what many people don't know is that [[Word of God]] has stated that Justice, the final boss of the first game, the Commander Gear, a large, powerful robot-type person with a noticeable crotch spike, is really a female and was a dear friend of Sol Badguy's.
* {{spoiler|Shale}} from ''[[Dragon Age]]: Origins'' is {{spoiler|a amnesiac golem who has a masculine personality and build. However, if you have Shale in your party during the "A Paragon of Her Kind" quest, it is revealed that Shale was once a dwarven woman named Shayle. Even Shale herself is stunned by this revelation.}}
** Her Voice is obviously female, and if you keep them both in the party she flirts with Sten constantly.
* In ''[[Mirror's Edge]]'', Faith spends part of the game chasing after {{spoiler|an assassin - who is also a runner like herself - who Faith assumes to be male}}. Much later, when Faith gets into combat with {{spoiler|said assassin}}, it is revealed that {{spoiler|it is none other than her treacherous best friend, Celeste}}.
* {{spoiler|Jack (AKA "The Convict"; AKA Subject Zero)}} in ''[[Mass Effect 2]]''. She's never actually physically disguised, but all you know before meeting her is that she has a [[Tomboyish Name]] and a nasty reputation. This reveal was spoiled in [[Trailers Always Spoil|the advertising]].
* Chris from ''[[Princess Waltz]]'' is taken to be a man by the main character. Even despite many hints and on mutiply occasions fusioning together to become a woman, the main character doesn't realize that Chris is actually a girl untill... well... Either way even the main character feels stupid for not getting the hint before.
* The sequel to ''[[Crystal Quest]]'' reveals your [[Flying Saucer]]—depicted in gameplay as a 16-pixel-wide circle—to be piloted by a ''space cow with six legs'' (who is, of course, a girl).
* {{spoiler|Monica}} from ''[[Dark Cloud]]'' 2 first appears disguised as a young child when you first meet her, and after {{spoiler|she defeats the [[Monster Clown]] who was trying to seize Max's [[MacGuffin]]}}, removes her [[In the Hood|hood]] and reveals herself to be a woman.
* {{spoiler|Alexis}} of ''[[Valkyria Chronicles II]]''. Her voice kinda gives her away, quite a few players were still confused by the fact the game's encyclopedia classifies her as male, and that she has a male character model in game.
* Julian from ''[[Growlanser]]''. Her portrait is a giveaway when you first meet her as an Imperial Knight (you can see she has cleverage if you examine closely the portrait where she hold her sword) It was stated that Imperial Knights does not allow females to join, thus she hid her gender (though her 2 fellow companions Oscar and Lyell already found out and choose to ignore).
* Jayle from ''[[Valkyrie Profile]]''. A noblewoman [[Jeanne D'Archetype]] who disguises herself as a man in order to join Gerabellum's order of knights. Only her commanding officer knows of her disguise but says nothing about it, as he's [[Sweet on Polly Oliver|fallen for her]].
* In ''[[Disgaea 2: Cursed Memories]]'', everybody assumed Overlord Zenon is a male, but turns out  {{spoiler|Rozalin was the reincarnated Zenon}}, though  {{spoiler|the game's "reincarnation" mechanic allows non plot characters to reincarnate into any class, event the opposite sex ones}}.
** Note that {{spoiler|Rozalin}} is very clearly female. This is more of a case of The Girl Is Samus.
* Subverted in ''[[Hydorah]]''. Throughout the game, the player character is conspicuously helmeted, but is revealed in [[All There in the Manual|official artwork]] to be  {{spoiler|male}}
* ''[[Dragon Fable]]'' has Vilmor. She was assumed to been a male not only by the PC, but also by a majority of the players, despite obvious hints early on into her storyline. Was even referred to as male in a [[All There in the Manual|Newsletter]].
* The player character of ''Faria'' is only represented by an androgynous [[Super-Deformed]] sprite, and gender is not revealed until after she's saved the princess ({{spoiler|the fake one, that is}}).
* Subverted with Alex Wesker in [[Resident Evil 5]]'s DLC "Lost In Nightmares." Fans initially assumed that Alex Wesker was likely to be female due to a lack of third person gender identifiers in the memo revealing Alex's existence. However, the lack of gender pronouns was in fact the result of a shoddy localization attempt by the localization team. In the Japanese version, it is made very clear that Alex is male.
* In ''[[Fire Emblem: Awakening]]'', there's a masked swordsman/AntiHero who shows up early in the game, Marth. [[Super Smash Bros.|Previous incarnations of]] [[Fire Emblem Akaneia|that Character]] have been, while some what Androgynous, but definitely male... Turns out "Marth" is actually [[Lady of War|Lucina]], [[The Hero|Krom]]'s time-traveling daughter... [[The Reveal]] is actually quite [[Crowning Moment of Heartwarming|touching]].

==  [[Visual Novels]] ==
* Inverted in ''[[Fate/stay night]]''. [[Lady of War]] Saber is obviously a female knight, but it isn't until later on that we learn she is actually {{spoiler|the legendary [[King Arthur]]}}, who used magic to disguise herself as a man because {{spoiler|[[The Woman Wearing the Queenly Mask|she felt that the British probably wouldn't obey a Queen]].}}
** ''[[Fate Nuovo Guerra]]'' follows tradition and chocks one up with a certain Lancer from [[The Trojan War]], though it wasn't so much a disguise as it was "[[Politically-Correct History|sexist historians]]" who didn't like how a girl was getting all that booty and kicking all that ass.
* ''[[Phoenix Wright: Ace Attorney]]: Justice for All'': Phoenix doesn't learn Manfred von Karma's child's gender until facing her in court. {{spoiler|Shelley de Killer incorrectly guesses that [[Gender Blender Name|Adrian Andrews]] is a man, thus proving that he's never met her in person.}}
** In what is most likely an oversight, Phoenix refers to Engarde's manager correctly as a "she" during the initial interview, despite having no information on his manager beyond her existence.
*** This was most likely due to the manager's name being very gender ambiguous, which plays a key role in the case and was something the writers intended.

==  [[Web Comics]] ==
* Miko Miyazaki from ''[[The Order of the Stick]]'' does this. For about eighty or so strips, she appears only as a blue-hooded figure, until she takes on the Order of the Stick, at which point she drops her hood and we see that yes, she is in fact female (and, [[Informed Attractiveness|judging from Roy's reaction]], fairly attractive). Roy plays her Bob for a while, until he gets put off by her [[Holier Than Thou|personality]]. This wasn't that drastic, as she seemed more ambiguous than masculine prior to this.
** Before [[The Reveal]], she doesn't even seem to be human.
* Also initially appearing as a hooded figure was {{spoiler|the previous Wotch}}, Miranda West of ''[[The Wotch]]''. Her initial appearance was in the very first story arc. Her reveal was at the end of the ''fifteenth''.
* {{spoiler|Ashido}} from ''[[Inhuman]]'' is shown to be an example of this when another character walks in on her changing.
* [[Everyone Calls Him "Barkeep"|Peregrine Mendicant]] of ''[[Homestuck]]''. The [[Word of God|author]] never intended her to actually have a gender at all, but [[Sure Why Not|gave in to fan speculation]].
* Pratos the Bounty from ''[https://web.archive.org/web/20130719183412/http://www.drunkduck.com/Jix/ Jix]'' ends up being both a female Ambis named Aranis and Jix's cousin. A possible nod to Samus Aran.
** Jix herself was thought to be male until her brother Romulos revealed her true identity (it's hard to tell what gender a small furry alien is unless you are able to see anything).
* {{spoiler|Shadow}} from ''[[A Modest Destiny]]''. She spends a good amount of time in the comics as this until an incident where Maxim [[Thanks for the Mammary|grabbed her]] [http://www.squidi.net/comic/amd/view.php?ep=1=100 breast], and it's not shown who she is until much later.
** When the previously killed [[The Ace|Crimson Blade]] shows up at the Vampire Lord Fluffy's castle, Fluffy's bat familiar flies off with the helmet, revealing that the new Crimson Blade is a girl. Expecting this trope, Fluffy immediately tries to hit on her, but actualy fails miserably.
* [http://www.interrobangstudios.com/potluck/index.php?strip_id=1084 This] [[Ensign Sue Must Die|Interrobang]] [[Trigger Star|Studios]] comic where [[Super Mario Bros.|Luigi]] complains to Link about some gay Bounty Hunter in Orange armor who asked him out.
* ''[[Gunnerkrigg Court]]'': The [[Something Completely Different|interim comic]] ''City Face 2'' introduces a magpie named Bobeyes. In a bit of [[Painting the Fourth Wall]], the [[Shout Box]] below the comic features [http://gunnerkrigg.wikia.com/wiki/City_Face_2_comments commentary by in-universe characters] - one of whom is a magpie going by the username "magpie55". He thinks Bobeyes is a pretty cool, tough guy, and is as surprised as anyone to learn that Bobeyes is a girl. From his commentary on the final comic page, it's obvious that he's smitten.
* [[Inverted]] in ''[[Hanna Is Not a Boy's Name]]'''s [http://hanna.aftertorque.com/?p=4 first] [http://hanna.aftertorque.com/?p=5 two] strips, as [[The Ishmael|{...}]] [[Gender Blender Name|naturally assumed]] that "[[The Pollyanna|Hanna Cross]]" would be a woman. Played straight [http://hanna.aftertorque.com/?p=23 a short time later] when [[Involuntary Transformation|bat!]][[Fully-Embraced Fiend|Adelaide]] was introduced.

== [[Web Original]] ==
* {{spoiler|Tex}} in the ''[[Halo]]'' [[Machinima]] series ''[[Red vs. Blue]]: the Blood Gulch Chronicles''.
** In a semi-aversion of the usual way this trope is carried out, even after [[The Reveal]] her appearance is never feminine in any way. The sole differentiating factor is really her voice.
* {{spoiler|Spriggs}} in the ''[[Halo]]'' [[Machinima]] series ''Spriggs''.
* Hilariously parodied in [[The Onion]]: "[https://web.archive.org/web/20100219135230/http://www.theonion.com/content/node/31739 Hotshot Test Pilot Removes Helmet, Reveals Female Status]".
* In the fifth season of ''[[The Guild]]'',  {{spoiler|Zaboo's two Master Chief lackees}} are revealed as hot girls.
* Cordell the dark elf from ''[[Gaia Online]]'' was not particularly concealed, just androgynous, having been introduced as a champion of the dark elves willing to compete in the ([[Aborted Arc|non-canon]]) Reject Olympics on behalf of Durem. She was found to be female when an aggressive [[Yaoi Fangirl]] [[No Fourth Wall|invaded the track]] and [[Skinship Grope|felt her up]]. "[[Memetic Mutation|Hay UR not a bishie!]]"

== [[Western Animation]] ==
* Sarasim in the ''[[Teen Titans (animation)|Teen Titans]]'' episode "Cyborg the Barbarian". Cyborg is her "Bob."
* In the 2003 ''[[Teenage Mutant Ninja Turtles 2003]]'' series, the turtles meet a lithe blue mutant called Quarry, leader of a pack of formerly human test subjects of Shredder's weird genetics experiments. When the turtles are able to find a (range-limited, at first) cure, it is revealed to their surprise that Quarry is a woman.
** Helped along even more, is the fact that they watched a video where they see a [[Red Herring|man strapped to a table and turned into something that looked like Quarry.]]
* The ''[[X-Men: Evolution]]'' version of X-23 isn't revealed to be a girl ''or'' a young teenager initially, though she did look awfully ''small'' for a ninja/secret agent/whatever she was supposed to be disguised as.
* Parodied by Quackor (The Foul), the [[Evil Counterpart]] of (Dial "M" For) Monkey in ''[[Dexter's Laboratory]]''.
* In ''[[The Flight of Dragons]]'', the animated movie loosely based on the book by [[Peter Dickinson]], the [[Ragtag Bunch of Misfits|band of heroes]] is saved from a pack of thieves by a Robin Hood wannabe. When the knight in the group goes to thank the mysterious archer, "he" takes off "his" cap, and the audience is treated to a slow-motion shot of long, glistening, red hair as it flows down below her waist. The knight is speechless.
* Red Claw, a villain created exclusively for ''[[Batman: The Animated Series]]''. A terrorist leader whose name was notorious internationally, almost no-one knew that she was a woman at first. Even Batman was a little surprised when they first met:
{{quote|'''Batman:''' Red Claw is a woman? 
'''Red Claw:''' Is that a problem? 
'''Batman:''' Not at all. I'm an equal-opportunity crime-fighter.}}
* ''[[SpongeBob SquarePants]]'' parodied this trope, when Sandy Cheeks took off her diving suit in one episode. [[The Ditz|Patrick]] exclaimed in shock "Sandy is a girl?!" although everyone in Bikini Bottom should be more than just aware, that Sandy is female. In fact she's very popular with the towns boys.
** Played more straight in the medieval episode.
* In an episode of ''[[Family Guy]]'', Chris is conflicted over kissing a friend named Sam... Until he finds out she's a girl.
** Another episode features a talk show where it's [https://web.archive.org/web/20171204194151/https://www.youtube.com/watch?v=TCQBZmT2M8c revealed that a girl's boyfriend]... {{spoiler|is a woman. Actually, a horse. Actually, a broom.}}
* In the second season of ''[[Wakfu]]'', {{spoiler|the Masked Boufbowler}} ends up as this.
* ''[[The Simpsons (animation)|The Simpsons]]'' parodied it in ''Homer Of Seville'' when Homer was being chased down by a horde of rampaging Opera fans ([[It Makes Sense in Context]]) and was saved by a helmeted motorcyclist dressed in black leathers. When the errant saviour takes off the helmet she says "That's right I'm a woman" in a [[What Do You Mean It's Not Awesome?]] overdone way before Homer remarks in [[Dull Surprise|stilted speech]] "A lady motorcycle driver. What is this, [[The Twilight Zone]]?".
* An old ''[[Looney Tunes]]'' cartoon features Daffy forming a rivalry with a small duckling. He realizes he can't bring himself to hurt someone that small, so he uses Phlebotinum-powered growth pills to force the duckling to grow to his size... only he can't bring himself to hurt ''her'' after that, either. There are other things he can bring himself to do with her, though...
* In ''[[The Grim Adventures of Billy & Mandy]]'', Mandy does a classic by pretending to be a boy on Billy's baseball team, Billy believing girls can't play baseball even though Mindy has a team of her own (which she uses to beat them silly twice).
* ''[[Danny Phantom]]'' had one episode that involved a video game which Danny and Tucker are wrapped up in but can't defeat a gamer who constantly outwits them at every turn. Near the end of the episode they find out the gamer is Sam, which is practically humiliating as earlier in the episode they mocked Sam thinking due to a girl, she wasn't good at gaming. So her smugness in the reveal is justified.
* ''[[Avatar: The Last Airbender]]'' has Smellerbee who was dressed like a boy and, despite having a girl like voice, made it hard to tell which gender she was. It wasn't until "The Serpent's Pass" episode when Jet's group meet Iroh and Zuko that her gender is revealed after Iroh mistakenly classifies her as a boy and she angrily corrects him.
** Also the episode "Warriors of Kiyoshi". Sokka is surprised (to say the least) to find out that it wasn't men who ambushed them but a pack of teenaged girls.
** For the viewers, a good chunk of the Fire Nation army, if Zhao's speech in "The Blue Spirit" is anything to go by ("We are the sons and daughters of fire, the superior element!")
* On an episode of a Saturday morning cartoon based on ''Raggedy Ann and Andy'', Ann and Andy get rescued by a helmeted, laser toting space warrior. Warrior turns out not only to be a girl but a [[Everything's Better with Princesses|princess]].
* Arguably, [[Happy Tree Friends|Flaky]]. [[Word of God]] States she is, in fact, a girl.
* One of the main villains of ''[[The Condor]]'', Taipan, is revealed to be {{spoiler|Tony's girlfriend Valeria who wanted to have "''some fun''" with him before she kills him.}} Helped by the voice distorter and masculine nature of her costume.
* The ''[[Super Mario Bros Super Show]]'' had a [[Zorro]]-themed episode, where the Zorro [[Expy]] turned out to be the waitress from the local cafe, who's exposed at the end of the episode when she forgets to take off the fake mustache.
* ''[[Futurama]]'' Leela did this, but with a [[Paper-Thin Disguise]], so only other characters where surprised.
*  In ''[[The Incredibles]] 2'', ElastiGirl initially presumes [[Big Bad|Screenslaver]] is a man, a belief only enforced when she has to fight a hypnotized - male - victim forced to act as a stand in. In truth, Screenslaver it the [[Devil in Plain Sight|trusted sister of her benefactor.]]
* In the [[Valentines Day Episode]] of ''[[The Berenstain Bears]]'', Brother's hockey team played a ''very'' tough team called the Beartown Bullies; the ''toughest'' member of this team was the goalie, who was eventually revealed to not only be a girl, but Brother's secret admirer.
* ''[[Samurai Jack]]'':
** In "Princess Mira and the Bounty Hunters", there is a masked bounty hunter who everyone assumes to be a man. They are all shocked when she takes the mask off, revealing her identity as Princess Mira.
** In "Jack and Farting Dragon", the eponymous dragon seems male at first, talking to Jack in a masculine voice. When Jack decides to help it by crawling inside its stomach to find out what's making it sick, he eventually learns otherwise: the reason is [[Monster Is a Mommy| a baby dragon that is partially hatched]], lodged in the obviously female dragon's womb.
* Night Owl, one of the United Heroez in the ''[[Miraculous Ladybug]]'' special ''Miraculous New York''. A female hero with [[Powered Armor]] with a masculine voice while in-costume. Her stated reason for the deception is that Night Owl is a [[Legacy Character]], all previous identities having been male, although it's strongly implied in this case that this Samus is a Girl because [[Badass Gay| Samus is Also a Lesbian.]]

== Other ==
* Used in a Finnish ad for the army, where paratroopers are making a training landing in a forest and ''It's Raining Men'' plays. The song cuts when the troopers remove their helmets, revealing that they are all women. Thanks to conscription, Finland doesn't need to advertise the army to men.
* Another commercial for a high-grade beer shows the hands of the brewmaster at work, as the narrator praises the skill of those hands. At the end, the narrator says that they're focusing on the brewmaster's hands because she's not a particularly-attractive woman.
* [[wikipedia:Chevalier d'Eon|Chevalier d'Eon]] kept people guessing until the very end.
** As it turns out, at least biologically speaking s/he was male, though it's possible that s/he was an early example of a transsexual.
*** Sadly, in real life [[Le Chevalier d'Eon|no ghosts were involved.]]
* There was a stagecoach driver in the American West named [[wikipedia:Charley Parkhurst|Charley Parkhurst]]. One-eyed Charley was known for his toughness and could handle anything, up to and including armed bandits. After his death (at age 67), the person who laid him out discovered "Charlie" was a woman, and her birth name turned out to be Charlotte.
** A tribute of sorts is given in the second and fourth Blackadder series, where a girl named Kate pretends to be a young man named Bob Parkhurst.
** A similar discovery was made about jazz musician [http://www.straightdope.com/columns/read/1060/whats-the-story-on-the-female-jazz-musician-who-lived-as-a-man Billy Tipton (nee Dorothy Lucille Tipton)], following "his" death. Even "his" adopted sons and at least one sexual partner didn't know "his" true gender.
* Lots of people tend to call unfamiliar dogs "boy" on first sight, assuming they're male until proven otherwise.
* ''My God! It's a Woman'', the biography of Australian aviatrix Nancy Bird.
* The [[Science Fiction]] author James Tiptree Jr. was discovered, after much controversy and one prominent author penning an essay on how it was ''impossible'' and ''inconceivable'' that James could be a woman, to be a lady named Alice Bradley Shelton. The fact that she wrote many stories where gender took a major role did not help.
** George Sand, birth name Lucile Dupin, also qualifies.
* [[J. K. Rowling]]. Apparently, some people were surprised to learn the real name. This was [[Moustache De Plume|deliberately invoked]] by the publisher because their initial target audience was young boys who they felt might be put off by a female author.
** This is pretty common with female authors who write outside traditionally "feminine" genres. S. E. Hinton. K. A. Applegate. C. J. Cherryh.
** In the olden days, women who ran businesses would often take advantage of this or run the business through their husband, the legal owner.
** Inverted after ''[[Equal Rites]]'', where many assumed Terry Prachett to be a woman based on the book's feminist themes.
* [http://www.redbullusa.com/cs/Satellite/en_US/001242981626958 This Red Bull ad], the biker is a woman. And deaf.
* Jack Prelutsky's children's poem "The New Kid on the Block" describes the titular new kid as a terrible [[The Bully|bully]] who "likes to fight and picks on all the guys"; and ends with the line, "I don't care for her at all".
* Played for laughs in one "Tales from the Duck Side" comic in ''[[MAD]]'' magazine, where police surround a hotel in order to arrest the Invisible Man. The invisible perp denies being the Invisible Man, but the police don't believe the claim until they order him to get dressed, and [[Pronoun Trouble| "he" puts on lady's undergarments.]] 
* [http://www.youtube.com/watch?v=whEVftJWBjA&NR=1#t=2m8s A beautiful real-life example, except for the fact that it says "Samantha" on the side of the cockpit.]
* [[Gender Flip]]: The video [http://www.youtube.com/watch?v=_TBd-UCwVAY "It's Time"], shot from the perspective of someone who falls in love with a man and builds a relationship with him. The video ends with the man proposing marriage, and the camera pulls back to reveal that the point-of-view character was [[Queer Romance|another man this whole time]]. The video was heavily promoted by gay marriage advocates, causing many people to not even realize that the POV character's gender was supposed to be a [[Twist Ending]].
* [[Real Life]] example: In the 2012 Orange Bowl, a West Virginia player celebrated by tackling the Orange Bowl mascot. [http://www.youtube.com/watch?v=xsK6OKfLCqo This] is his reaction upon learning that the mascot was played by a woman.
* A truly weird example, a 2,000-year-old mummy discovered in 1826 was identified as a male due to interpretation of hieroglyphics on the casket. Modern technology in 2021, however, including a Computed tomography scan and multiple X-rays, reveal the mummy is not only the remains of a woman, but one who was pregnant at the time of death, an unborn fetus still in her womb.
