* In ''LightNovel/IveBeenKillingSlimesFor300YearsAndMaxedOutMyLevel'', after Azusa defeats the dragon Laika, she demands that Laika make up destroying her house (on accident) during the battle. The [[BreakTheHaughty thoroughly cowed]] Laika asks to return home first to retrieve reparation money from their DragonHoard. The next day, Azusa is shocked when a cute girl in ElegantGothicLolita clothing introduces herself as Laika in a [[VoluntaryShapeshifting humanoid form]]. The anime adaptation supports the deception by applying a distortion to her voice which makes her sound male, which disappears after the reveal.

* Combined with SamusIsAGirl in ''Manga/NegimaMagisterNegiMagi'': unlike most examples, the BountyHunter with the naughty tentacles actually ''is'' a CuteMonsterGirl, and it turns out the tentacles and stocky build are from a set of PoweredArmor she wore. She's still a huge pervert nonetheless.

Contrast (or compare?) ViewerGenderConfusion, when it's the viewers who are surprised. See also SamusIsAGirl, MonsterIsAMommy and YourTomcatIsPregnant.

* Monster may be stretching the term slightly, but in the Wiki/SCPFoundation, there is [[spoiler: Dr. Wondertainment]]

* One 2E supplement about the ''Literature/{{Dragonlance}}'' D&D setting has a section on minotaur society, complete with an in-character narrator who'd been captured by sea-going minotaurs. When this character asks the ship's captain about minotaur family life, the captain gruffly points out that the husky, wide-horned first mate who's been holding the narrator's hands behind his back throughout their conversation is, in fact, his wife. This was in sharp contrast to the few pieces of artwork depicting minotaur females, which tended to be [[BoobsOfSteel unsubtle]] about things.

* Early in ''LightNovel/IveBeenKillingSlimesForThreeHundredYearsAndMaxedOutMyLevel'', when Laika shows up at Azusa's doorstep to challenge her, Azusa (and the audience) assumes her to be male until she shows up the next day in her more obviously feminine humanoid form. The anime supports the deception by applying a distortion to her voice that makes her sound male, which disappears after the reveal.

** The trope proper is referenced earlier by the park's chief geneticist, Henry Wu, who says everyone always refers to the adult ''TyrannosaurusRex'' as a "he" despite being aware that it is female, like all dinosaurs in the park are supposed to be.

* The Horta in the ''Series/StarTrekTheOriginalSeries'' episode "[[Recap/StarTrekS1E25TheDevilInTheDark The Devil in the Dark]]" turns out to be female...and the "silicon nodules" that miners on its planet are destroying turn out to be her eggs.
* A particularly horrifying example of this trope occurs in the ''Series/NightGallery'' episode "The Caterpillar". A man pays to have a romantic rival murdered by having a carnivorous earwig placed in the man's ear. The plan goes wrong, however, and the next morning he awakens to find that [[LaserGuidedKarma the earwig has been placed in his ear instead, and has crawled inside his head]]. [[FateWorseThanDeath He endures weeks of agony as the earwig eats its way through his brain]], but he remarkably survives the ordeal. He is then told by a doctor that the earwig was female... [[spoiler: And it laid eggs.]]

* The dragon Hooktail in the English version of ''VideoGame/PaperMarioTheThousandYearDoor''.[[note]]In the original Japanese, she's clearly female from the beginning.[[/note]] Despite the character being the first major boss of the story, you don't learn this until the final chapter--where [[BigBrotherInstinct her older brother]] is the first of ''[[BossBonanza many]]'' bosses, and is [[ItsPersonal predictably pissed off at you for what you did to his sister]]. Even the characters assume Hooktail to be male, and refer to her using male pronouns.

* In ''Film/{{Dragonheart}} : Vengeance'', Lukas is quite surprised to find out that Siveth, the Dragon he's been searching for, is female.

* In ''Webcomic/{{Sinfest}}'', it's Christmas Eve, and Sleaze (demon anti-Slick) [[http://www.sinfest.net/view.php?date=2012-12-24 wishes for "Hot Bitches"]]. Cerberus, TheDevil's three-headed dog, appears at the door. Sleaze revises his wish.

* Happens in ''Literature/{{Animorphs}}'' with the first free Hork-Bajir. "You mean there's such a thing as a female Hork-Bajir?"

* Combined with SamusIsAGirl in ''Manga/MahouSenseiNegima'': unlike most examples, the BountyHunter with the naughty tentacles actually ''is'' a CuteMonsterGirl, and it turns out the tentacles and stocky build are from a set of PoweredArmor she wore. She's still a huge pervert nonetheless.

* In the ''Diamond and Pearl'' series of ''Anime/{{Pokemon}}'', Jessie manages to capture a Yanma, which then evolves into a Yanmega, a [[DreadfulDragonfly huge vicious-looking dragonfly]] with an extremely deep reverberating voice. During a later episode, a female Togepi uses the move Attract (which only works on targets that are the opposite gender of the user) to immobilize the main cast's Pokemon, including Pikachu, Piplup, Croagunk and Meowth (all four of whom are male). Jessie's Yanmega [[NoSell remains unaffected]], and after putting two and two together, Jessie's shocked to find out that her giant bug Pokemon is, in fact, a female.

* Dedoria in ''WebVideo/DragonBallZAbridged'', she was a male in the source material but to Vegeta's shock and disgust, she's revealed to a woman here, even regarding herself as the most beautiful (and fertile) on her home planet (until Frieza blew it up). Vegeta then proceeds to kill her and "repress the truth" of what he had just learned.

* The title character in ''Literature/{{IT}}'' [[spoiler:is protecting Its eggs, which will assumedly hatch into MindScrew monsters just like her.]]

** In ''Discworld/GuardsGuards'', the dragon tormenting the city is revealed at the last minute to be female, to the surprise of the city watch.
** "Chelonauts" in ''Discworld/TheLightFantastic'' are trying to go over the edge to determine the sex of Great A'Tuin, the turtle the Discworld travels on.
