[[caption-width-right:300: [[PunnyName Not all bitches are this easy to spot.]]]]

-> ''Look like the innocent flower, but be the serpent under 't.''
-->-- '''Lady Macbeth''', ''Theatre/{{Macbeth}} Act 1 Scene 5''.

You meet someone you think is a really NiceGuy/Girl, or perhaps you meet a favorite celebrity for the first time, thinking that they'll be just as [[NiceCharacterMeanActor warm-hearted and cool as they are on camera]]. However, something happens to show their [[BeneathTheMask true colors]], revealing an immature brat, [[NoHeroToHisValet total]] {{Jerkass}}, or even outright {{villain}}.

Congratulations. You've just met the Bitch in Sheep's Clothing -- the polar opposite of a JerkWithAHeartOfGold.

The WoundedGazelleGambit is a favorite tactic of this sort of antagonist, and if they are genuinely evil, expect them to be a VillainWithGoodPublicity.

It's also worth mentioning that this trope isn't exclusive to female characters. The title is a play on "AWolfInSheepsClothing," and can apply to any gender. All it requires is a person appears to be nice, but is actually cruel and/or manipulative.

In romance plots, the Bitch in Sheep's Clothing is usually trying to date, dating, or about to marry another character, and is hiding their [[BeneathTheMask true colors]]. Occasionally, the Bitch in Sheep's Clothing genuinely ''was'' a nice person... but suffered sudden CharacterDerailment in order to [[DerailingLoveInterests remove their status as a love interest]] for another character. In any case, expect them to make an EngineeredPublicConfession in one form or another.

In some cases however, a Bitch In Sheep's Clothing can be sympathetic. Many lighter cases involve a scenario in which a fairly flawed yet well intentioned character make themselves out to be more benevolent than they really are ([[SmallNameBigEgo especially if they have a high profile of themselves]]). More often than not, this charade falls apart and their true persona blasts out, usually in an extreme manner that makes them look even worse than they usually are. In some cases, a Bitch In Sheep's Clothing can lean more towards JerkWithAHeartOfGold if they aren't too busy hiding their unpleasant qualities with an overenacted facade, instead of showing their genuine (and usually resented) redeeming aspects. Maybe someone will seem like this, then you realize they are just a type B {{Tsundere}}.

See also: DevilInPlainSight, VillainWithGoodPublicity, WartsAndAll. A RomanticFalseLead is [[DerailingLoveInterests often like this.]] The EnfantTerrible is also a related trope (possibly the AnnoyingYoungerSibling with SiblingRivalry from Hell). For a version specifically concerning actors and actresses, see NiceCharacterMeanActor. For a more extreme version of this trope, see BaitTheDog, where the 'bitch', oddly enough, likes to KickTheDog.

Not to be confused either with AffablyEvil or BewareTheNiceOnes, where the person is genuinely nice rather than just putting up a facade (though both tropes can be [[CharacterDerailment derailed as such]] if overexaggerated, as can a Bitch In Sheep's Clothing evolve into one of the former via CharacterDevelopment). Contrast With TookALevelInJerkass, where the character was genuinely nice and became... well a {{Jerkass}}. Also compare and contrast JerkWithAHeartOfJerk.

Contrast BitchAlert for a bitch who lets everyone knows that she's one. Compare AWolfInSheepsClothing. Contrast also with SheepInSheepsClothing for a character ''believed'' to be a BitchInSheepsClothing and eventually subverted.



[[folder: Anime and Manga ]]
* Inaho Hitomebore from ''Master of Mosquiton 99''. To the school, she's the most exalted student; to those unfortunate enough to travel with her, she is a miser who uses her friends as tools and makes the guy who loves her do stupid and humiliating things while she ignores his pleas and thinks of riches.
* ''Anime/{{Pokemon}}'' has a few examples:
** One episode during the Johto saga had a Teddiursa who used its cuteness to steal and fool people. When it ran into Ash's group, it stole their food and framed Ash's Chikorita and Totodile for what it did, and Misty was easily tricked. However, they eventually find out the truth, and when its cute charade fails to work on them again, it quickly drops the "sheep's clothing" part and just keeps on eating the food that it stole from the gang in defiance.
** An earlier episode, "The School of Hard Knocks," had Giselle, a student at Pokémon Tech who bullied the younger students under the guise of tutoring, who effortlessly beat Misty in a Pokémon fight and dismissed Ash's statement that trainers have to be friends with their Pokémon, even mocking Ash's Pikachu. Ash, of course, [[BreakTheHaughty puts her in her place]] by beating her with said Pikachu.
** In the episode "Ghoul Daze", a seemingly friendly ghost girl mind-controls Conway and almost tricks him into falling off a cliff. Thankfully, it doesn't work because he's saved by a [[DarkIsNotEvil Dusknoir.]]
** Iris's Emolga, as the viewers undoubtedly realized from the moment she was introduced. She'd better watch out, 'cause [[ActionGirl Snivy]] don't take no shit.
** ''Anime/PokemonMewtwoReturns'': Domino initially appears to be a cute and slightly ditzy college student and assistant to Cullen Calix, but soon reveals herself to be an [[EliteMooks elite agent of Team Rocket]] working directly under Giovanni himself, and the second-in-command in his plan to recapture Mewtwo.
* In ''Anime/AshitaNoNadja'', Nadja's best friend, Rosemary Applefield, starts as a sweet NaiveEverygirl with a huge inferiority complex. After she's "betrayed" by Nadja and snaps, she [[spoiler: makes everyone in her surroundings believe she ''is'' the real Nadja, fooling a whole noble clan as a part of a conspiracy that will make her boss, Hermann Preminger, the true heir to the clan.]] To make these plans work, Rosemary shamelessly lies, tells half-truths, manipulates, steals/destroys various stuff, and gleefully takes part in [[spoiler: Hermann's]] various schemes, rarely losing her innocent facade, and even being ready to ''[[ChronicBackstabbingDisorder betray]]'' her boss if she gets to keep her new "princess" status that way. [[spoiler: And even when she ''admits'' her defeat and willingly returns everything to Nadja, Rosemary bitterly recognizes that [[BrokenBird she's been so deeply changed by such experiences]] that she just ''can't'' be the genuinely sweet kid she once was.]]
* Ami from ''LightNovel/{{Toradora}}'', although, with CharacterDevelopment, she becomes more of a JerkWithAHeartOfGold in sheep's clothing, and eventually, just a JerkWithAHeartOfGold.
* Oushima from ''Manga/DeadTube'' is a beautiful young girl, the head of her high school’s Film Research Club, kind and understanding towards the awkward and introvert [[TheProtagonist Protagonist]], Machiya; [[BullyHunter she saved him from bullies before]] and invited him to be the Cameraman of her Club, earning his adoration in the process. Turns out all of Oushima’s efforts were an intricate plan to one day make Machiya the star of her pet project, a Snuff Film which plot was about the idiot loner that loved his Senpai above all, getting his heart demolished as he finds out that she was going to kill him, and just to add salt to the injury Oushima was having orgies behind back, this fact which she makes sure Machiya gets know before executing her plan. To Oushima’s surprise the filming doesn’t go as planned, [[BewareTheNiceOnes and the not-so-stupid Machiya gets her killed instead]].
* Anko's wart in Episode 14 of ''ThrillerRestaurant.'' When she takes over the real Anko's body and mind, she makes herself appear as a bright, attractive girl. In reality, the wart is arrogant, manipulative, and absolutely sadistic. [[spoiler: Thank goodness Shou noticed something was wrong with her.]]
* Lust is one briefly in ''Manga/FullmetalAlchemist''. As Havoc's girlfriend Solaris, she was apparently charming, sweet, and attentive, and was very supportive of him as he got used to living in Central. Havoc is understandably a bit shocked when she turns out to be an evil quasi-immortal being who [[spoiler: ''literally'' stabs him in the back, and then goes on to try to kill Mustang, Hawkeye, and Alphonse]], all the while thoroughly enjoying herself.
** Let's not forget Shou Tucker. "Nina, want to play with daddy?"
* Quattro of ''Anime/MagicalGirlLyricalNanohaStrikerS''. Though she initially appears to be a [[{{Kawaiiko}} seemingly playful, childlike]] {{Meganekko}}, this is a facade to conceal her [[SmugSnake true personality]].
* Miya Miya of ''Manga/BambooBlade''. In classic Power-Rangers style, she's added to the team as the "Pink" ranger for her cute and sweet nature. It's all a lie, though. She's actually the most terrifyingly brutal character in the show. The team names her real persona "Black", and it comes with its ''own aura of violent intent.'' On one occasion, it startles Pink Miya Miya when just her grimace from painful feet terrifies Sayako and Kirino into ''[[PoseOfSupplication dogeza]]'' because they think "You were Black Miya Miya!"
* Polly (Pururun) from ''Anime/SamuraiPizzaCats'', while sweet and charming at first, is actually a real bitch when she gets annoyed, often taking her frustrations out on innocent customers.
* Sei Arisaka from ''Manga/HimechanNoRibon'' acts like a perfect gentleman towards everybody around him but Daichi seems to be the only one who realises he has an alternative motive.
* Shou from ''Manga/SkipBeat'' has carefully engineered his public image to look like the perfect Teenager Cool Prince, and he isn't shy to step over anyone he considers beneath his "grand destiny" of becoming the most popular artist in Japan. He is also selfish, immature, petty, absurdly self-centered, and completely unable to cope with any reaction which isn't admiration or adulation.
* Tomoe Marguerite from ''{{Anime/Mai-Otome}}'' [[DevilInPlainSight puts on airs of sweetness in front of the staff at Garderobe]], but has no problem hurting or otherwise manipulating others to get her way, especially when Shizuru is involved. She even acts nice to Arika herself (in her mind, her main rival for Shizuru's affection), but mainly while others are watching, and reveals her true colors to Arika when she first sees her after the WhamEpisode.
* [[{{Yandere}} Akira]] [[HatesTheJobLovesTheLimelight Kogami]] from ''Manga/LuckyStar'''s [[ShowWithinAShow Lucky Channel]] segments.
* Izaya Orihara from ''LightNovel/{{Durarara}}''. Nice friendly guy. Smiles a lot. Says he loves people. Cheerful attitude. Convinces people to kill themselves.
** In fact, one of the main reasons why Izaya hates [[TooDumbToFool Shizuo]] is because Shizuo was able to see right through him the very moment they first met, despite being DumbMuscle. Hence, the HateAtFirstSight meeting. That's why whenever weird stuff starts happening in Ikebukuro, Shizuo immediately blames Izaya, stating that when stuff like that happens, 99.9999% of the time, it's Izaya's fault. Disregarding the shoddy statistics, he's more or less right.
* Zange from ''Manga/{{Kannagi}}''.
* Sakurako Sanjou of ''Manga/HanaYoriDango'', who, in all continuities (manga, anime, drama), befriends [[PluckyGirl Tsukushi Makino]] and looks like a kind, shy, cutesy type...at least up until she has Tsukushi drugged, takes pictures of her unconscious, in compromising positions, and distributes them freely among the school, leading to her assault by other students. This is revealed as a part of her master plan for seducing/exacting revenge upon Domyoji, Tsukushi's SlapSlapKiss-y love interest, which also involved her spending a fortune on plastic surgery, dropping out of school in the past, and hiring professional goons to assault ''various'' characters (not only Tsukushi). The reason for all of this is that ever since she was in kindergarten, Domyoji [[DisproportionateRetribution bullied her and called her ugly]]. Talk about one WomanScorned.
** However, through CharacterDevelopment, she arguably becomes ALighterShadeOfGray, GoodIsNotNice case of a sympathetic FemmeFatale, who beats up the other [[BitchInSheepsClothing Bitches in Sheep's Clothing]] when they try to kill Tsukushi. Just goes to show that despite all the terrible acts of evil and violence committed against Tsukushi and her friends, almost all villains end up with a HeelFaceTurn, and this series firmly belongs on the lighter side of the SlidingScaleOfIdealismVersusCynicism. This would make Tsukushi a rare KnightInSourArmor that [[EarnYourHappyEnding SUCCEEDS in her goals]].
* Sousuke Aizen from ''Manga/{{Bleach}}''. Actually, he's probably the ''best'' example of the trope, because he's actually the ''BigBad''. And prior to his introduction, he spent at least a hundred years maintaining the nice guy façade.
** Kuugo Ginjou, with added MemoryGambit at no extra charge.
* Mariya Shidou from ''Manga/MariaHolic'' fits this to a T -- sweet, helpful princess of the school on the outside, sadistic ManipulativeBastard (and VillainousCrossdresser) on the inside.
* Natsu Tanimoto of ''Manga/KenichiTheMightiestDisciple''. To most of the school, he's the [[{{Bishonen}} extremely handsome]], incredibly intelligent, multi-talented, kind-hearted honor roll student. To the members of the Shinpaku Alliance, however, he reveals his true nature: an angry, violent, short-tempered {{Jerkass}} who is prone to stomping them into the ground for even looking at him the wrong way. However, thanks to some CharacterDevelopment (most of it courtesy of Kenichi's little sister Honoka), he's now more of a JerkWithAHeartOfGold, though you'll be hard-pressed to get him to admit it.
* Sae from ''Anime/PeachGirl'', who uses her RavenHairIvorySkin [[TheIngenue ingenue]] appearance as an advantage over "gangster-looking" DarkSkinnedBlonde Momo (she tans easily). Out of jealousy that Momo has the attention of two hot {{Bishounen}} classmates, Sae pretends to be her friend but starts whispering rumours about her, repeatedly pulls the WoundedGazelleGambit to make people hate her, blackmails her mutual crush into pretending to be Sae's boyfriend instead to protect her, and tells her (next) boyfriend that Momo has rape fantasies about him and demands that he fulfills them - then tricks Momo into going somewhere with him, and ''drugs her into a stupor''. And this was just what she'd done by the 2nd volume.
* In a not-uncommon {{Hentai}} example, Yuriko from ''Anime/MoonlightLady''. At first, she seems to be a YamatoNadeshiko who honors family tradition. She is. She just doesn't care that her daughter gets raped as a part of it. She's not above trying to steal her son-in-law-to-be, either.
* Doe-Doe Eun of ''Manhwa/PigBride'' is publicly a sweet YamatoNadeshiko maiden who enjoys being demure and needlework. But it's almost entirely an act to snare the main lead, who has made no secret that that's the kind of girl he likes. When there are no boys around, Doe-Doe is a ruthless gangster-type who bullies the other girls so they won't move in on her territory. What makes her a touch more sympathetic is that she is stuck in a YouCantFightFate competition with the title character, rendering all her efforts fruitless from the start.
* Akira of ''Manga/SamuraiDeeperKyo'' fits this trope in his interactions with Yuya. To the male characters, he's a complete and utter bastard, but to Yuya, he continues to act sweet even after she knows it's an act.
** A more classic example in the series would be Antera, who has the appearance of a young girl but once killed a man by ''squeezing his head until it popped''.
* Ran from ''Manga/UruseiYatsura'', although a bit on the ''{{Yandere}}'' side. Ryoko, on the other hand, is a better example.
* ''Manga/RanmaOneHalf'' has [[TheBarnum Nabiki Tendo]]: a [[FauxAffablyEvil pleasant, good-humored]] (if mildly snarky) girl who [[MoneyFetish places more value on her wallet than on human life]]...to the extent that she once offered to sell her (temporary) fiance to the other members of his UnwantedHarem (and would have, if they hadn't had a spontaneous attack of intelligence and realized that they could kill her instead of pay her), and let the same UnwantedHarem members know that he was about to marry [[OfficialCouple Akane Tendo]] because she thought they'd bring cash presents to the wedding that she could steal. One might also consider [[AnimeChineseGirl Shampoo]] to be one of these, with her capacity to go from sweet, bubbly, and [[TheGlomp crushingly]] [[NoSenseOfPersonalSpace affectionate]] to a calculating, destructive warrior willing to [[MurderTheHypotenuse kill off her romantic rivals]]...but she makes no effort to hide her darker side from anyone, least of all Ranma, so she might not count.
** During the introduction story of "Pantyhose" Tarou, when Shampoo finds Akane alone and tied up in a cave, she thinks that this is a perfect opportunity to MurderTheHypotenuse and let Tarou take the blame. While she was initially quite blatant and straight-forward in her attacks on others, by this point in the manga, she had become quite duplicitous.
* In ''LightNovel/{{Kampfer}}'', [[spoiler:Kaede Sakura]] would qualify. [[spoiler:[[SarcasmMode Such a sweet girl, handing out stuffed animals to her closest friends and acquaintances]]. Through the early and mid portions of the anime, she's seemingly oblivious to any and all of the strange occurrences happening around her. It's only later that her cold calculating side comes to the forefront.]]
* ''Manga/MyBrideIsAMermaid'':
** Lunar appears to be a sweet, incredibly {{Moe}} IdolSinger. Turns out, she's really a bit of a bitch, especially when it comes to one-upping Sun. Although she does have some [[JerkWithAHeartOfGold genuinely nice]] moments.
** Maki's character design was basically created to embody as much {{Moe}} as possible, her being an eight-inch-tall ShrinkingViolet. Then she turns out to be a Yakuza Enforcer who spends the bulk of the series attempting to kill Nagasumi, who she despises, all while keeping up the cute facade so Sun doesn't catch on. Of course, like Lunar, she is not without her PetTheDog moments.
* Tomomi in ''Anime/LadiesVersusButlers'' definitely qualifies. While the end result is for the best, she usually grins in an evil way just to make her UnluckyChildhoodFriend Akiharu and UnknownRival Sernia squirm for her satisfaction.
* ''Anime/CodeGeass'':
** [[spoiler: Empress Marianne VI Britannia, AKA Lady Marianne "The Flash", AKA Lelouch's mother, is presented for most of the first season as practically a PuritySue that was TooGoodForThisSinfulEarth, and was killed because of it while protecting her daughter. However, when we finally meet her, late in R2, she turns out to be a BloodKnight that had used her Geass power to survive, using a young girl (who she constantly MindRaped) as a SoulJar. Also, she was working with her husband TheEmperor on his AssimilationPlot, and since she lacks his FreudianExcuse, she comes across more as a LadyMacbeth with shades of KnightTemplarParent than he does.]]
** Schneizel, an apparently [[TheWisePrince reasonable man]] in contrast to the rest of his ilk; that is, until he starts showing [[ManipulativeBastard his true colors]].
* [[spoiler: Jin]] in ''Anime/InnocentVenus''. [[spoiler: he actually manages to keep the act up for half the series, honestly appearing to be a NiceGuy with only the occasional slip-up [[SpoilerOpening (and a scene in the opening)]] to hint that he's not the main protagonist, but is, in fact, an outright villain.]]
* Yukino from ''Manga/YakitateJapan''. The first time she appears outside of a flashback, she acts very friendly to Tsukino and apologizes for defiling her mother's ashes. It's all a lie, but this facade has her grandfather wrapped around her little finger.
* Shinghi from ''Manhwa/ZippyZiggy'', especially at first. It's pretty much the entire point of his character. The same with his father.
* Surprisingly for a harem story, ''Manga/HayateTheCombatButler'' has three, all seeming to be on the same side of the good vs evil line. All three seem to have taken up this because of love, but don't have the mental instability of a Yandere.
** Athena is the strongest case, at least as a little girl: she acted wonderful and loving to Hayate, even training him to be stronger, but any time she got a hint of him not being single-mindedly in pursuit of her, she didn't hesitate to attack, usually Hayate himself. She appears to have grown out of it.
** Mikoto (Wataru's mother) also seems harmless, but uses wiles to try to convince/coerce Wataru to live with her while belittling both Saki (his maid) and Sakuya (one of his potential love interests).
** Mikado seems to be acting this way, an unassuming old man, but with significant evil intentions just under the surface.
* ''Manga/HoneyHunt'': Yukari is Yura's mother, a beautiful and talented actress. But her beauty is only skin deep, as shown throughout the series. She is never at home for Yura and is very selfish. On all of her interviews, she lies and says that she and Yura are close and spend much time together, when in reality, she is a cold and distant parent. While her husband was having an affair, she was having one of her own with Yura's neighbor, Shinsuke (who Yura had a crush on). She and her husband were only together for the sake of their careers and their images, they didn't love each other. The two of them even agreed on a rule with each other that they would stay married as long as they hide their own adulterous affairs. After she decided to divorce Takayuki, however, it is shown that she has no intentions of taking care of Yura, and only cares about improving her image in the eyes of the public who had originally thought she was the "ideal mother".
* Hana Mizuki from ''Papillon''. She has a beautiful angelic appearance and acts in a sickeningly sweet manner towards people, but underneath that is an extremely manipulative and selfish girl who acts terrible to her sister for the sole reason that she wants to prevent her sister "from ever attaining happiness" out of jealousy that boys seem to like her sister's personality more than hers. Kyuu compares her to a rose, stating she is "covered in thorns".
* Mayu Okada from ''Manga/KaguyaHime''. She is very much a {{Yandere}} for Akira, and doesn't let men or women near her. She has a sweet appearance but, beneath that, is very manipulative and will do anything to get her way, such as pretending to be sick and fainting on the spot to get attention.
* Mimi Yoshioka from ''Manga/LovelyComplex''. She is in love with Otani, and brings him milk every day so he could reach her height, about the same as Risa's. Since Otani does not have feelings toward her but does have feelings for Risa, she becomes jealous of her. She acts accordingly two-faced between them both: acting sweet and cute whenever Otani is around, yet slipping into [[{{Yandere}} psycho mode]] and acting malicious to Risa whenever Otani is not around. She becomes less of a jerk later on, though.
* Tsuzuki from ''Manga/PrivatePrince'', aka Miyako's first boyfriend who started out acting super kind to her, [[spoiler: but only used her to make his own research better. And later comes back to her life and tries to use her ''again''.]] [[spoiler: Untypically for this kind for character, he gets better.]]
* ''Manga/KimiNiTodoke'': Kurumi acts sweet and nice to gain Sawako's sympathy, then tells her to keep her hands off Kazehaya. She gets better, though.
* Ibuki Yagami from ''Anime/MaisonIkkoku'' is a StalkerWithACrush to her [[TeacherStudentRomance substitute teacher]] Godai, and she is extremely manipulative and aggressive in getting what she wants. She often makes use of her girlishly innocent appearance to deceive people.
* ''Manga/OniisamaE'': Fukiko and most of the senior members of the Sorority. They'd sell their grandmothers if it would bring them the slightest advantage (after inviting her to a fancy dinner, nonetheless).
* Heloïse Villefort of ''Anime/{{Gankutsuou}}''. She seems perfectly normal in her first few appearances, with a warm motherly appearance and pleasant smile. She is the stepmother of Valentine and is the second wife of the crown prosecutor Villefort. She is the biological mother of her young son Edward, from her first marriage. Valentine is to inherit all of the fortune, leaving her stepmother jealous because Edward doesn�t get a single penny. So when the Count seduces her and innocently introduces her to toxicology and gives her a deadly ring which releases poison, Heloïse becomes murderous and tries to poison Valentine and her husband, as well as inadvertently almost poisoning Albert and one of the servants of the Villefort household. And she does all this while maintaining her angelic motherly facade up till near the end of the series when her husband finds out what she's been doing and points out that she's nothing more than a murderous woman who's completely lost it before he sends her to an insane asylum.
** As well as Andrea Cavalcanti aka Bendetto. He briefly seems to be a highly cultured fop and a decent guy, and continues to put on that persona, but he's really a total psychopath.
* ''Manga/{{Naruto}}'': Kabuto Yakushi. He usually presents himself as this harmless, bumbling oaf with NerdGlasses who showed up to help Naruto and his teammates on occasion but is, in fact, a sadistic ManipulativeBastard and a subordinate of the BigBad Orochimaru.
* ''Manga/ElfenLied'': During Lucy's childhood, she made friends with a seemingly sweet, kind-hearted girl who promised to keep the fact that Lucy was taking care of a puppy a secret from a group of boys who frequently bullied her. Eventually, the boys find out about the puppy and [[MoralEventHorizon beat it to death in front of Lucy while making her watch]]. Turns out, the girl Lucy made friends with had deliberately told the boys about the puppy, and while she's pretending to cry about it and feel bad about what she did, we see her smile through her tears. Lucy then snaps and kills her along with the bullies.
* Captain Shears in the ''VideoGame/StarFox'' comic "Farewell, Beloved Falco" - Shears, a military officer on Titania, tells Fox that he needs help combating remnants of Andross's army who are planning a counterattack. [[spoiler: In fact, Shears is trying to re-build Andross and is trying to fool Fox into attacking Falco and his group]]
* ''Anime/YuGiOh'':
** Seto Kaiba, in his first appearance in the manga and the first anime, pretends to befriend Yugi, and has Yugi's grandfather's Blue Eyes White Dragon switched with a copy. When Yugi figures this out and calls out Kaiba on the switch, Kaiba loses the facade and whacks Yugi in the face with a briefcase.
** Kaiba does it a second time during Death-T in the manga. He pretends that he has forgiven Yugi and simply wants to let him and Jonouchi have a good time; once Yugi discovers that his grandfather is in the battle arena, Kaiba drops the pretense of being nice. Yugi notices the difference in how he acts around a disgruntled ex-employee and how he acts around him, but doesn't suspect enough to see through him until it's too late.
** Nezumi in the manga - Yugi and Jonouchi meet Nezumi at school. Nezumi claims that a gang of bullies attacked him and that he needed help in dealing with them. [[spoiler: In fact, Nezumi was ordered by Hirutani, Jonouchi's old middle school friend and now enemy, to have Jonouchi and Yugi lured to the abandoned warehouse so that Jonouchi could be forced to re-join Hirutani's gang.]]
** Volume 1 and [[NoExportForYou Season 0]] had Ms. Chono. To the teachers and staff, she is just an incredibly nice and beautiful teacher who does incredibly well in getting her students to behave, and the only flaw she has is her not-so-suspiciously-poor track record for arranged dates and marriages always being called off. To the students, however, she is the "wicked witch of expel", who noticeably has as much bitchiness as she does make-up on her face, and who expels students for even the slightest twitch and has taken delight in starting dates with men just to tug at their heart strings and then shatter them to pieces. Yami Yugi reveals her true nature, but how he does so varies between the manga and the anime.
** IV Arclight from ''Anime/YuGiOhZexal''. When near his fans, he creates a facade in which he is very polite and respectable, while in reality, he's extremely sadistic and cruel, to the point of where he showed a young child being tortured via a television screen to his older brother just to see his emotional pain during their duel.
** And Sora from Anime/YuGiOhArcV. He acts like a cute, innocent kid to get what he wants, but is actually blunt, rude, and smug. This is even reflected in his deck: he uses [[RidiculouslyCuteCritter Fluffal]] monsters, which can be fused to create demented and terrifying monsters.
* Subverted in ''Manga/AimForTheAce'' with Reika. She seems to turn into a bitch at first, despite still being a good sport. Over the course of the series, [[spoiler: especially after Coach Munakata's death]], she [[CharacterDevelopment turns into a much more sympathetic character]].
* Ayumi in ''Gu-Gu Ganmo''. She appears to be a cute, gentle girl in the first few episodes, but eventually, she shows her true colors and turns into a manipulative, self-centered, and aggressive little bitch. Oh, [[{{Gasshole}} and her farts could wipe out whole towns]].
* Henri from ''Anime/FutureGPXCyberFormula''. For most of ''ZERO'', he appears to be a cheerful rookie who seems to be nice to most of the racers, but in reality, he's a vengeful person who wants to make Hayato suffer for taking away his dream. His father was a former racer who pushed Henri to be the best in racing to make him the youngest champion in CF history, but when [[spoiler:Hayato got the title before him, his father started drinking and then abandoned him,]] which triggered his resentment towards Hayato. He mellows out at the end of ''ZERO''.
* Fiore of ''Manga/TheWorldGodOnlyKnows'' is actually introduced to the audience as an agent of [[TheRemnant Vintage]] from her first appearance, and it isn't until after she [[spoiler: [[MoralEventHorizon stabs Kanon]]]] that we see the sheep's clothing that she wears around her fellow New Devils.
* In ''Manga/{{Bakuman}}'', [[spoiler:[[SmugSnake Toru]] [[JerkAss Nanamine]]]] acts polite and cheerful around the editors, apologizing for publishing his oneshot online after it got passed over for an award, and the main characters note that he seems somehow overly polite. When he's alone with the main characters, though, he reveals that he has nothing but contempt for editors, who he views as outsiders who know nothing about manga. He keeps up his persona around his editor until he reveals that he is corresponding with 50 people online for ideas, and, while [[BreakingLecture taking advantage of his editor's lack of confidence and need to get a series]], threatens to go elsewhere if his editor doesn't go along with what he does as the 51st person.
* [[Manga/{{Monster}} Johan Liebert]] is one of the most pleasant and polite people imaginable. He's incredibly classy, cultured, intelligent, and a very good listener. He's also practically the embodiment of pure evil. All of his "nice actions" just make it easier for him to get into your head, MindRape you, and either kill you, get you to kill others for him, or [[DrivenToSuicide make you kill yourself.]]
* Remi Mizuchi in ''Manga/SukebanDeka''. She seems to be TheOjou in OjouRinglets, and seems like the WhiteSheep of the family compared to her ObviouslyEvil siblings. Then, in the OVA, she suddenly leaps into full-fledged terrorism, and she becomes a major recurring villain in the manga.
* ''Anime/MasterOfMartialHearts'' is ''literally'' riddled with multiple instances of the trope:
** FauxActionGirl Miko, the cute, helpless strange girl and cuddly and cheerfully [[AFriendInNeed friend in need]] who drove Aya to the whole mess? [[spoiler: Nothing but a bitchy mark]].
** {{Heterosexual Life Partner|s}} Natsume, Aya's ''best friend forever''? [[spoiler: Actually a revenge-obsessed bitch willing to trample, maim, and MindRape a whole bunch of innocent women and girls just to screw with Aya. The whole time faking friendship towards her just to rub it in her face during TheReveal]].
** Natsume's brother, Aya's love interest? [[spoiler: Ruthless enough to kill in cold blood people he actually ''hired'' for his plot, is Miko's lover, and in league with the other two to ruin Aya's life forever]].
** Natsume's mom, the epitome of the trope. [[spoiler:Currently a CuteMute mom, secretly a StepfordSmiler, deeply inside, a raging beast that, due to have catastrophically lost her voice, mental sanity, and freedom because of Aya's mom when both of them were plucky {{Action Girl}}s (and she actually tried to kill her opponent's parents, it seems...), masterminded the whole convoluted plot, pressuring her offspring and their cousin Miko to send dozens of young girl to same fate as her just to ensure Aya was reeled in]].
* ''Manga/KimiNoIruMachi'' gives us the character Eba Rin, main heroine Yuzuki's younger step-sister. Even before the manga begins, Rin has managed to make her sister so uncomfortable that she moves out to be as far away from Rin as possible. Eventually, she drops her meaner tendencies and gets along with her sister, but still loves to {{troll}} just about everyone else.
* ''Manga/OnePiece'':
** In the story Monsters of ''Manga/OnePieceWanted'', we have [[spoiler:Cyrano]]. He seems to be a nice guy at first, but he's actually a huge asshole.
** From the main manga we have [[MadScientist Caesar Clown]]. He ''acts'' nice toward his subordinates (as well as the kids on his island), but in truth he couldn't care less about them and isn't above experimenting on them, intentionally getting them hooked on drugs, or even ordering their deaths if he has reason to.
** In a more general sense, everyone who took young Robin in after the Ohara incident was this, as they only took her in so they could sell her location to the Marines and get the bounty that was on her head. As if doing that to a ''child'' wasn't already horrible enough, some of them even had the balls to claim that it was Robin who was being ungrateful, repaying them for their kindness by running away.
* In ''Anime/RevolutionaryGirlUtena'', [[AlphaBitch Nanami]] comes off as one of these in her first episode, presenting herself as a potential friend for Anthy before setting her up for humiliation at the ball. More prominently, Shiori's quiet, polite demeanour hides extremely bitter feelings towards her childhood friend Juri.
* [[spoiler:Saki]] from ''Manga/FamilyCompo''. At first she seems like a YamatoNadeshiko but we quickly learn that's a cover-up since she's a GoldDigger and a ManipulativeBitch.
* Masahiro from the manga ''Teacher's Pet''. He's aggressive and [[spoiler:forces sex onto the protagonist several times]] but he's quiet and [[{{Bishonen}} feminine looking]] so no one guesses it.
* Momoka from ''Manga/HighSchoolGirls'': Jealous of her older sister Yuma's friendships with the other main girls, she spreads a rumour that Ayase is cheating on her boyfriend, leading Ayase to assume it was Yuma and cause them to fall out, gloating about how it only took her spreading one rumour to shatter ''one'' friendship and how it would only be a matter of time before she destroyed the rest, all whilst pretending to befriend the other girls and generally behaving in a cutesy, peppy manner. Luckily, Eri figures it out.
* Asakura Ryoko from ''LightNovel/HaruhiSuzumiya'' is the friendly, polite, attractive, class representative who always has a kind word and a smile... until she tries to stab Kyon because she's bored and she thinks killing him will get Haruhi to do something interesting.
** Emiri Kimidori fits this as well, as she [[spoiler: doesn't give damn when Nagato is made ill by contact with the Sky Canopy Dominion. This causes Kyon to call her a "monster" like Asakura]]. Basically all the IDSE interfaces except Nagato.
* Masato Kadowaki from ''Manga/ArataKangatari'', who acts like a typical nice guy in front of everyone on his first day. The facade doesn't last very long, as he already resumes bullying Hinohara like he did in middle school within the first few days.
* ''Manga/KyoKoiOHajimemasu'': Poor [[spoiler:Rika]] seems so nice, timid, fragile and innocent...until we find out she uses her apparent weaknesses to sleep around, manipulate people and set herself as the victim, all the while laughing at the others' expense.
* When Nurakami first meets Nanami in ''Manga/KamisamaKiss'' she acts like she wants to do her a favor by taking over her position as a land god and removing the burden of responsibility from her. Really, she is just trying to claim Nanami's familiar, Tomoe, as her own and once Nanami says no she stops acting nice.
* ''Manga/KotouraSan''
** Hiyori initially hates how Haruka seemed to swipe Manabe from her, so she tries to alienate and bully her in episode 2. Once Manabe realizes what's going on, he confronts her about it and calls her out on her bullying. Although later she had a change in heart, and [[IWantMyBelovedToBeHappy wished Manabe to be happy instead]].
** This is how Yuriko presents herself as to Dai'chi, but he points out plainly that she's just fooling herself in thinking she's that cold-hearted. While she does have a partially hidden agenda regarding [[{{telepathy}} Haruka]] (presumably to make Haruka well-known as a psychic in order to [[ClearTheirName vindicate Yuriko's mother]]), she still seems to care about her greatly.
* [[spoiler:Camilo]] from ''Anime/RomeoXJuliet''. He seems to be a nice man and a good friend for Conrad, but he really turns out to be a SmugSnake, once he showed his true colors [[spoiler:by giving information on the Capulets' hideout towards the Montagues.]]
* [[spoiler:Lebreau Fermet Viralsque]] from ''LightNovel/{{Baccano}}''. He appears to be a nice, calm and loving figure. But his true nature is of a cruel sadist who tortured Czeslaw Meyer for a couple of centuries; he's the mastermind of the tragedies of the 1700 arc, killed [[spoiler:Monica, Huey's wife]], and is the responsible for all the bad stuff that happened to the immortals.
* ''LightNovel/ChuunibyouDemoKoiGaShitai'' has Shinka Nibutani, who seems to be a sweet, friendly, responsible YamatoNadeshiko class rep... She's actually a (semi-)reformed Chuunibyou with a violent, selfish temper who's trying desperately to be 'normal'.
* Fujisaki from ''Manga/OneechanGaKita'' acts this way initially, although she has a FreudianExcuse, since she was bullied as a kid, and boys treated her with contempt even when she tried to be nice.
* In ''Webcomic/AxisPowersHetalia'' we have:
-->'''[[NationsAsPeople Russia]]''': I have [[YouJustToldMe terrible secret]] no one will guess because of my [[CuteAndPsycho sweet]] [[StepfordSmiler face]]!
* ''HunterXHunter'' has a male example with Pariston, a member of the Zodiac who's charming, charismatic, scheming and utterly insufferable to the other Zodiac members, and spends most of the Chairman Election just casually trolling the other Zodiac members and having the entire election wrapped around his finger. [[spoiler: It turns out these qualities are precisely the reason the late and former Chairman Netero made him a member of the Zodiac, and after he's won the election and had his fun he happily steps down from his position and hands it over to the best candidate, revealing that he did it all to honor Netero one last time.]]
* Shyamalan from the first season of ''[[BirdyTheMighty Birdy the Mighty: Decode]]'' fits this trope so well he might as well have read the page quote by Lady Macbeth and thought it was a bold statement about how to live his life. He acts friendly and charming to just about everyone, but in reality he's a SocialDarwinist who [[spoiler: plots to use an alien superweapon to wipe out most of humanity and spare only those whom he's willing to accept as just as special as he is]]. The fact that he [[FaceOfAnAngelMindOfADemon looks really cute and cuddly for the most part]] contributes greatly.
* [[spoiler: Uta and Itori]] from ''Manga/TokyoGhoul''. They pretend to be helpful and kind, but in reality have been manipulating Kaneki into one misfortune after another. And all of it simply as part of one enormous [[ItAmusedMe prank]].
* In ''Manga/BlackLagoon'', Greenback Jane comes across as this. While she's no threat in a fight, she's quite manipulative, and threatens [[spoiler: to seduce Rock]], prompting a threat from Revy to [[spoiler: [[PrisonRape make Jane Revy's bitch.]]]]

[[folder: Comic Books]]
* Surprisingly, Franchise/SonicTheHedgehog fits this trope in the [[ComicBook/SonicTheComic Fleetway comics]]. While he was hero worshiped by all of Mobius as a fearless symbol of hope, he was actually a self-centered, immature {{Jerkass}}. This comes back to bite him in the ass in ''Webcomic/SonicTheComicOnline'', where the sheep's clothing gets flung off and he ends up becoming a HeroWithBadPublicity. Once the public knew about some of his more questionable decisions that he made to try and save Mobius, all the {{Jerkass}} tendencies that people were willing to ignore made it easy for [[spoiler:Grimer]] to convince the public that he was a villain.
* Dean in ''My Faith in Frankie.'' Although ''he'' gives the excuse of being in Hell for ten thousand years during the day he spent dead, the very fact that he ended up in Hell implies that he was actually ''always'' like this, and now he just has a focus and outlet.
* At his very worst, ComicBook/{{Cyclops}} of the ComicBook/XMen (of at least a DarkerAndEdgier AntiHero in TheCape's clothing), in contrast to JerkWithAHeartOfGold {{Wolverine}}. Ignoring the complicated mess that is his love life, Cyclops tries to project the image of a wise and noble leader for mutants to admire while keeping dirty secrets from his teammates, such as the existence of {{X-Force}}, his personal mutant kill-squad. This is after he kicked Professor Xavier out of his own home because he kept secrets from Cyclops. To be absolutely fair to Scott, he really thinks all of this is necessary to ensure the survival of mutantkind after the various disasters of the past few years -- and he might be right. Still, at one point, Wolverine, X-Force's field leader, reminds Cyclops that his hands are just as dirty as any member of X-Force's, since Cyclops organized X-Force in the first place and gave them their orders.
%%* [[Webcomic/{{Dreamkeepers}} Tinsel]] has got to be this trope personified.
* Professor Kallisto Vangelis from [[ComicBook/LesLegendaires Les Légendaires]], when first introduced, was portrayed as one of the nicest guy in the show: he [[ParentalSubstitute had been like a father]] to the leader protagonist Jadina when she was a child, took care of her mother after she got incurably ill and took time to talk with the then disturbed Tenebris. In the next book however, he's revealed to have been controlled since his first appearance by a new villain named [[PuppeteerParasite Abyss]], who poisoned the same queen he had been healing, orchestrated Jadina's attempted execution, {{brainwashed|AndCrazy}} Tenebris into cooperating with him and [[AmbitionIsEvil attempted to rule Jadina's kingdom with Tenebris by his side]] (while [[IncestSubtext calling her his sister but suspectly treating her as... much more]]).
** This wasn't the real Vangelis doing, but notice [[EvilAllAlong it was Abyss controlling him all along since the character was introduced to the reader]], even when he was seemingly a nice guy.
* Thessaly of ''ComicBook/TheSandman''. She may look like a sweet young college-age girl, but in reality, she's a paranoid, millennia-old witch with a nasty habit of offing anyone who so much as annoys her.
* Indigo of [[ComicBook/BatmanAndTheOutsiders The Outsiders]] was a strange variation. She started off as a seemingly-homicidal robot, then got "reformed" into a cute RobotGirl, before finally being revealed as [[spoiler:the latest incarnation of Braniac]].
* ComicBook/{{Iznogoud}} tries to be this toward the Caliph. He is terrible at it, but the Caliph is so oblivious it still works anyway.
* If {{Dreamkeepers}}'s Tinsel doesn't qualify, with her deceptive nature, manipulation games, inner cruelty and absolutely evil personality, then it's hard to imagine who does.
* In ''ComicBook/{{Fables}}'', [[spoiler: Geppetto]] seems to be a nice old man, but underneath the exterior, he's ruthless, power-hungry and an inveterate schemer.

[[folder: Fan Fiction]]
* Jenny from ''Fanfic/EbonyDarknessDementiaRavenWayVsCanon'' seems like an average teenager who happens to enjoy {{Troll}}ing the internet. She then reveals herself to be a pretty nasty piece of work.
%%* Precia in ''Fanfic/GameTheory'', which is a sharp contrast to [[AxCrazy her canon temperament]].
* ''FanFic/AGrowingAffection'': [[spoiler: Homura appears to be the most kind and reasonable of the three Konoha elders. Turns out he was Gouki's man almost the entire story.]]
* ''Fanfic/AFutureOfFriendshipAHistoryOfHate'': When Regal Rule is introduced in Episode 4, he at first appears to be Rarity's long-awaited PrinceCharming, but it soon becomes apparent to the reader that he's trying to drive a wedge between her and her friends. [[spoiler: And then he turns out to actually be Megalos Tyrant, one of [[BigBad Ruinate]]'s [[CoDragons heralds]] (specifically, the element of arrogance).]]
* ''FanFic/AnAlternateKeitaroUrashima'' has Granny Hina, who tries to pass herself off as a CoolOldLady who's only got everyone's best interests at heart when she's really a ManipulativeBitch. Her true colors emerge when she doesn't get her way, and much of the conflict is spurred on by her attempts to force others to do what she wishes against their will.
* Lacie in ''[[Fanfic/FallinginDeeper Falling in Deeper]]'' is said to be one, with an obsession in being just perfect in everything. It's also implied that [[spoiler: she is behind the events that made Bridgette and Megan be sent to Arkham for mass murder]]. To give an example, when she first appears is when she meets Bridgette [[spoiler: who has ran away from Arkham and just escaped the Scarecrow]] and she teases her about all that happened [[spoiler: long enough to the Scarecrow finds her and takes her with him]].

[[folder:Films -- Animated]]
* [[spoiler:Lotso]] in ''WesternAnimation/ToyStory3''. In the ''Art of Toy Story 3'' book, the revelation of his [[AxCrazy true nature]] was said to be like "finding out {{Series/Mister Rogers|Neighborhood}} was a mafia don".
* Mother Gothel in ''Disney/{{Tangled}}'' pretends to be Rapunzel's loving mother, but in actuality, she was the woman who kidnapped Rapunzel as a baby because her hair was full of magic from the flower used to de-age Gothel that got crushed into medicine for Rapunzel's real mother, the queen.
* Hal from ''WesternAnimation/{{Megamind}}''. He's basically JimmyOlsen -- if Jimmy secretly hated Franchise/{{Superman}} and lusted after LoisLane. The Sheep's Clothing fools Megamind, who thinks that Hal is the kind of nobody who would become a hero if given great power. Instead, Hal goes FromNobodyToNightmare.
* ''Disney/{{Frozen}}'' gives us [[spoiler:Prince Hans]], who, in contrast to the NiceGuy façade he puts on for most of the film, turns out to be a ManipulativeBastard of some magnitude, whose [[EvilPlan plan]] is [[spoiler:to marry Princess Anna, with whom he fakes LoveAtFirstSight, then arrange for an 'accident' to befall Queen Elsa, making him King of Arendelle through his wife.]]
* [[TheDitz Sonata]] [[EnthrallingSiren Dusk]], from WesternAnimation/MyLittlePonyEquestriaGirlsRainbowRocks, is this- she seems like the nicest of the [[TerribleTrio Dazzlings]], but is in fact just as evil as the other two
* Lola the Main/GoldDigger lion fish from ''WesternAnimation/SharkTale''. She dismisses Oscar calling him "cute but a nobody." When Oscar becomes famous, Lola starts dating him much to Angie's jealousy and dismay. After Oscar finishes a sharkslayer stunt, Lola swims up to the cameras and [[ForcefulKiss forcefully kisses]] him, causing Angie to leave in jealousy anger and sadness. Once Angie confesses Oscar her feelings for him, Oscar rethinks his feelings and dumps Lola--which unfortunately, [[spoiler: leads to her great anger as she mercilessly slams him against the windows. Lola then crosses the MoralEventHorizon by arranging Don Lino to kidnap Angie in demand of Oscar's obedience even gleefully Angie's life to do so.]]
-->'''Lola''': You know, Sharkslayer, there's only one thing I like better than money: ''Revenge!''


[[folder:Films -- Live-Action]]
* The starter boyfriend of any female lead in any RomanticComedy. Sometimes, the nice guy veneer is so thin, you have to wonder HOW he manages to hide it at all from the woman, or why he even WANTS to marry her instead of just dumping her and moving on to the next girl?
* The mermaids from ''Franchise/PiratesOfTheCaribbean: On Stranger Tides'' - for such sexy, harmless-looking creatures, they sure are vicious.
* ''Franchise/TheChroniclesOfRiddick'': William J. Johns at first appears to be a clean-cut lawman and typical hero, but is ultimately revealed to be a self-serving, cowardly mercenary who doesn't give a damn about anyone but himself. [[AndThatsTerrible And if that's not bad enough]], he's also a morphine addict.
%%* Fairy Godmother from ''WesternAnimation/{{Shrek}} 2''. We assume all fairy godmothers are nice - this one definitely is not.
* The Bishop Edvard Vergerus from ''Film/FannyAndAlexander'' by ''Creator/IngmarBergman''. He seems fairly benign, if a little self-righteous, before pulling back the curtain to reveal a true sadist, justified by piety.
* Auric Film/{{Goldfinger}}, as stated in his TheVillainSucksSong:
-->"Pretty girl, beware of his heart of gold, this heart is cold!"
* Peyton Mott in ''Film/TheHandThatRocksTheCradle''. A very chilling example.
%%* [[spoiler: Verbal Kint]] in ''Film/TheUsualSuspects''.
* The ''Film/HarryPotter'' flicks have both Quirrel and Umbridge, who both seem quite benign on the surface, but are in fact quite evil. Heavy emphasis on the "bitch" part in the latter's case.
* David Simms in ''Film/TinCup''. Partly subverted in that Roy [=MacAvoy=] and all his friends already know this about David. Conversely, David's girlfriend (with whom Roy falls head-over-heels in love, naturally) doesn't realize that Roy's comments about David's true nature are accurate until the movie is almost finished.
** Simms is even dignified in romantic defeat. He's a nice guy ''and'' a complete asshole.
* Simone Clouseau in the original ''Franchise/ThePinkPanther'' ([[ValuesDissonance at least to a modern viewer]]). Because her husband Jacques is TheFool, she is able to successfully hide her professional ''and'' romantic connections to the jewel thief he is trying to capture, and ultimately helps frame him for their crimes. Since the thieves were the protagonists of the film, and were pulling a KarmaHoudini (Clouseau was the EnsembleDarkhorse who became the hero of the subsequent films after being a SympatheticInspectorAntagonist), the audience is supposed to be on their side. Unfortunately, even here, Jacques Clouseau is a JerkWithAHeartOfGold, so her behavior is rather [[TheUnfairSex cruel]].
* ''Film/CruelIntentions'': [[BigBad Kathryn]] [[VillainProtagonist Merteuil]] [[VillainWithGoodPublicity sets herself up]] as a model student, a popular, well-adjusted young woman, and a devout Christian, but in reality, she's a {{narcissist}}ic, [[TheAlcoholic alcoholic]] [[DrugsAreBad cokehead]] of an AlphaBitch who regularly goes out of her way to manipulate people and destroy their reputations and lives ForTheEvulz. By the end of the first movie, Annette and Cecile, two girls whom she had manipulated, circulate copies of her stepbrother Sebastian's journal, in which he had detailed Kathryn's true colors, to the public, flinging off the sheep's clothing.
* Regina from ''Film/MeanGirls''. Towards the very beginning, we're told that she's a bitch, but she seems to act perfectly civil to Cady. Then, of course, things begin to go downhill. A good example is when Regina insults someone's skirt after saying to the person's face that she liked it. This is obviously a call back to earlier in the film when she complimented Cady's bracelet.
** Cady herself becomes one of these toward Regina and her circle later in the film. A case of PayEvilUntoEvil given Regina's actions, but Cady's actions (turning her friends and on-again-off-again boyfriend against her, giving her "diet" bars that cause her to gain weight, attempting to publicly humiliate her) are still quite nasty, especially since she does them under the guise of friendship.
* George in ''Film/ThePhiladelphiaStory''. His [[BeneathTheMask true colors]] are revealed in his last scene.
* Macy in ''Film/TrickRTreat''. Actually, many characters in ''Film/TrickRTreat''.
* In the Creator/ArnoldSchwarzenegger comedy ''Film/JingleAllTheWay'', Creator/PhilHartman portrays his next-door neighbor, who appears to be a nearly perfect man: a devoted single father who dotes on his child, a master at cooking and home repair, and has a seemingly limitless supply of free time to devote to helping others. For most of the film, only Arnold can see him for what he really is: a SmugSnake whose every move and thought is dedicated to seducing every woman he comes across, whether they're single or not.
* In the live action adaptation of ''Film/TheCatInTheHat'', [[BigBad Lawrence "Larry" Quinn]] sets himself up as an ideal boyfriend and a top-notch real estate agent, while in reality, he's nothing but an unemployed FatSlob who only wants to marry the kids' mother for the money and constantly plots to get Conrad shipped off to military school. At the beginning of the film, only Conrad can see him for what he really is.
* The [[spoiler:Second Wife]] in ''Film/RaiseTheRedLantern''.
* Ray Zalinsky in ''Film/TommyBoy''. Tommy quips that he seems so genuine on camera. He then explains what a {{Jerkass}} he is when Tommy gets to Chicago to try and talk him out of buying the family business.
* In ''Film/TwentySevenDresses'', the heroine's sister fits this trope perfectly.
** It's very heavily implied that she's doing it to deal with her own loneliness, and they do make up at the end
* Karl in ''Literature/{{Blackout}}''. On the outside, he's a helpful, chivalrous NiceGuy, devoted parent, and recovering widower. But between his flashbacks, and his gradual loss of patience in the elevator, we learn that he's [[spoiler: a deeply sadistic and misogynistic NietzscheWannabe SerialKiller[=/=]rapist who staged his wife's suicide, and whose main reason for needing to escape the elevator is to clean up his [[TortureCellar bachelor pad]] before his daughter arrives and sees the corpse of his latest victim]].
* Katharine Parker in ''Film/WorkingGirl'' starts off as a BISC before progressing to being a DevilInPlainSight.
* In ''Film/LegallyBlonde 2'', the senator (played by Sally Field) is sweet and kind to Elle, becoming a mentor and friend quickly. She throws Elle under the bus the first chance she gets to gain a political edge.
* Eve Harrington in ''AllAboutEve''.
* Professor Catalan in the French action-comedy ''That Man From Rio'', a mousy, academic archaeologist who is kidnapped by folks who had just stolen a Mesoamerican statue which is the key to a vast treasure. The protagonists rescue him around mid-film, unaware that [[spoiler: he'd staged his own kidnapping and is after the treasure himself, along the way, murdering a former colleague and abducting a young lady he had been a surrogate 'favorite uncle' to]].
* Balraj's sister, Kiran and Mrs. Darcy, in ''Film/BrideAndPrejudice'' are not nice people at all.
* [[spoiler:Nina]] is perfect for the role of the ''Film/BlackSwan'', because she is a ManipulativeBastard, master of the WoundedGazelleGambit, and most importantly, [[CuteAndPsycho crazy]] enough to [[MurderTheHypotenuse do anything to get the role]]. ...[[MindScrew Perhaps]].
* [[Franchise/StarWars Palpatine]], full-stop, combining this with VillainWithGoodPublicity. As the Chancellor of the Republic, he had cultivated an image of himself as a kind, tea-drinking, grandfatherly figure who cares deeply for his planet, The Republic, and democracy. All the while, he was [[RunningBothSides running the Separatist forces]] as his alter-ego, Darth Sidious. Immediately upon being confronted by the Jedi, he shows his true colors as a sadistic, megalomaniacal, power-hungry ManipulativeBastard. In the public eye, he kept up his former facade, while using his new hideously deformed appearance to pull what was essentially a giant WoundedGazelleGambit and turn the Senate and public opinion against the Jedi.
** What's more is that even after the Empire unleashed the full force of its tyranny on the galaxy, he remained popular, and even those who hated Imperial rule generally did not see him as the villain. He continued to be seen as either the galaxy's benevolent hero who ended the Clone Wars, or at the very worst, as a weak-willed old man being manipulated behind the scenes by the likes of Tarkin and the Moff Council. Very few actually realize (or want to believe) that he is a megalomaniacal tyrant in complete control of The Empire.
** At one point, Mon Mothma even calls him this trope.
-->''"This Palpatine was a Rodian in Ewok's clothing!"''
* Michael Bishop from ''Film/{{Alien 3}}''. His smile after Ripley refuses his offer says it all.
* [[spoiler:Tony]] is revealed to be one at the end of ''Film/TheImaginariumOfDoctorParnassus'', although there are subtle hints dropped throughout the film that he's not as nice as he at first appears.
* ''Film/TheParentTrap'' has the step-mom-to-be being a sheep to the dad, and a bitch to everyone but. It's surprising how he doesn't see it, honestly, but then again [[WickedStepmother All Stepmoms Are Evil]].
* The ''Franchise/{{Scream}}'' series has a fair amount of these. On a lighter note, Rebecca is a memorable example in [[Film/{{Scream 4}} the fourth installment]]. On a darker one, Ghostface killers are usually this before TheReveal.
* Eddy of ''Film/{{Hick}}''. On the surface a [[TroubledButCute friendly Good Ol' Boy with perhaps some anger management issues]], underneath [[spoiler: a psycho killer and rapist.]]
* Ms. Quickly, to whom the father reluctantly proposes in ''Film/NannyMcPhee'' because he must marry by the end of the month or be cut out of his wealthy aunt's estate. She puts on a sweet front until the day of the wedding, when she coldly informs the children that they're all to be shipped off to boarding school at the first opportunity.
* In ''[[ThreeMenAndABaby Three Men and a Little Lady]]'', Mary's mother is on the verge of marrying one of these, completely unaware that her husband-to-be loathes her adorable child.
* ''Film/TheStepfather'' seems to play this straight with the '''step''' dad.
* ''Film/{{Predators}}'' has a Franchise/{{Predator}} clan putting on a planet [[WorldOfBadass a mercenary, a Israel Defense Force hitwoman, a Spetznaz commando, an African death squad trooper, a Mexican drug cartel enforcer, a death row criminal]]... and a doctor. Played by [[Series/That70sShow Topher Grace]]. [[spoiler:Who turns out to be a serial killer.]]
* A male example in ''Film/{{P2}}''. Thomas, the stalker/kidnapper, seems like an eager and helpful NiceGuy at first, but becomes more and more of a desperate psychopath as he loses control over Angela.
* [[Film/SherlockHolmes Professor Moriarty]] does a flawless impression of a benign, gentlemanly academic, complete with a fondness for feeding pigeons. In reality he's a [[LovesTheSoundOfScreaming sadistic,]] [[ManipulativeBastard manipulative]] [[TheSociopath sociopath]].
* ''Film/WelcomeToTheDollhouse'' has the tutu-wearing Missy. All she has to do is dance around clumsily and the parents are under her spell. Which pisses off Dawn no end.
* ''Film/RedRidingHood'' Prudence big time. When Valerie is chained up in the center of town, wearing a wolf's mask, and is being used to lure the Werewolf to his doom, she decides to say some spiteful things to her. Instead of apologizing to her for what was happening to her, she says that she deserves to be killed by the werewolf. She even hints that she might have been jealous of Valerie for a long time.
* [[spoiler:Holly Jones]] from ''Film/{{Prisoners}}''. [[spoiler:She's initially just an irritated but essentially good-natured mother trying to protect her son. It's all just a facade and she's actually a kidnapper and murder of children who did it all, along with her husband, to "crusade against God".]]
* Detective Mark Hoffman of the ''Film/{{Saw}}'' series. Outwardly, he presents himself as a hard-working, responsible, caring figure of law. It can fool you if one's not aware that Hoffman's a [[spoiler: ruthless, manipulative, and murderous DirtyCop as well as an apprentice of Jigsaw]].
* Lina Lamont in ''Film/SinginInTheRain''. Compared to reality, howevery, this film offers two interesting twists: Debbie Reynolds, who is dubbing Lamont in the film, was herself dubbed by Betty Noyes, and laid-back, long-suffering NiceGuy Don Lockwood is played by irritable perfectionist Creator/GeneKelly, the ''real'' Bastard in Sheep's Clothing.
* Walter in ''Film/BigEyes'', initially comes off charming and romantic, but is actually manipulative and abusive.
* ''Film/{{Saved}}'': Hilary Faye can give the LovableAlphaBitch vibe, but she's a straight up AlphaBitch. On good terms with her so as long as her outlooks on religious beliefs aren't opposed. Oppose them in any way and you'll see just what sort of friend she is and that her act of kindness is solely built on being TheFundamentalist and EgocentricallyReligious.

[[folder: Literature]]
* [[RichBitch Blanche Ingram]] in ''Literature/JaneEyre'' coos and fawns over Mr. Rochester to the point where it almost sickens the reader -- though the company takes it as proof of her love -- while giving Jane death glares and making cutting remarks that manage to sound innocuous while obliquely insulting Jane. Her love of Rochester, however, is put to a quick end when he tells her (lying) [[GoldDigger that his fortune is far smaller than she thought it to be.]]
* A few in Creator/TamoraPierce's Literature/TortallUniverse:
** Princess Josiane in the ''Literature/SongOfTheLioness'' quartet, after being turned down by Prince Jonathon, turns out to be quite literally AxCrazy. This happens a lot to Copper Islands rulers; [[InTheBlood due to excessive inbreeding]], see below.
** Bronau, the wayward prince in ''Literature/DaughterOfTheLioness'' is a Balitang family friend who once courted Winnamine. He and Sarai are quite attracted to each other, but he's a gossip and makes racist remarks in his flirting when the Balitangs (who are not racist) are trying to get along with the locals. Then, [[spoiler:he starts plotting against his brother and sister-in-law and tries to abduct the child king. When that fails, he attacks the Balitang estate and kills Mequen in an attempt to make Sarai marry him]].
** Imajane and Rubinyan put up a good front of being {{Reasonable Authority Figure}}s when talking to the Balitangs in person. Piss them off--especially Imajane, who's the daughter of previous insane king--and you'll be nailed to the docks with your kids thrown to the piranhas.
* Caroline Bingley in ''Literature/PrideAndPrejudice'' is all friendliness to Jane... until she learns that her mother's family are in trade. Wickham is a male example: he seems like a wonderful, charming guy, but he's TheCasanova and a con artist.
* Lucy Steele in ''Literature/SenseAndSensibility''. She might seem like a harmless ditz at first, but she turns out to be grasping and passive-aggressive; knowing that Elinor Dashwood and Edward Ferrars were close, she makes a ''big'' point of talking about her engagement to him in front of Elinor. Elinor being the way she is, just sits back and takes Lucy's nastiness, but deep down she's hurting, and badly. [[spoiler:Good thing Lucy ends up with Edward's brother instead...]]
** Willoughby as well, who is perfectly charming on the surface but a complete bastard underneath, actually worse than Wickham by a large margin.
* Tommy Toledo in the short story "I'll Never Stop Loving You, Tommy Toledo" by Ellen Conford.
* Darth Zannah sort of qualifies. In ''[[Literature/DarthBane Dynasty of Evil]]'', she makes an act of being nice to people just to get favors, and she seduces a guy in book 2, resulting in his death.
** Given the Sith philosophy towards self-realization, which means first fulfilling one's capacity to experience ''genuine'' affection, friendship, passion, and love (thus, directly rejecting the Jedi concept of detachment), and then attaining personal liberation and fulfilling one's capacity to experience pain and loss by betraying the objects of such affection in the deepest imaginable ways...really, not only does this come with the territory, BitchInSheepsClothing is probably the ''best'' outcome which can be hoped for.
* Several of the Professors of Defense Against the Dark Arts in ''Literature/HarryPotter'':
** Quirinus Quirrell appears to be a nice but nervous guy and is constantly bullied by professor Snape. [[spoiler: This is all but an act. He's been working with Voldemort the whole year. His nervousness is probably real.]]
** Gilderoy Lockhart is [[SmallNameBigEgo annoyingly boastful]] but is certainly affable and friendly with Harry. It turns out that he's a fraud and all his alleged accomplishments were stolen from other witches and wizards on whom he inflicted the Memory Charm.
** [[Characters/HarryPotterMinistryOfMagic Dolores Umbridge]] in ''Literature/HarryPotterAndTheOrderOfThePhoenix''. Uber-feminine pink frills, kitten pictures, and passive-aggressive personal style go with an obsession with personal and governmental power. The bitchitude is meant to be transparent to the reader and sympathetic characters, but the intended hypocrisy is clear enough. Her inner bitch is meant to be out of the closet by the time she uses a magical instrument of torture on the hero.
** During his school years, Tom Riddle is this. While Dumbledore can see through his facade, likely because he had seen Tom without it back at the orphanage, everyone else believes him to be an honorable, hardworking student, and a hero who caught the Heir of Slytherin.
* Several examples in ''Literature/ASongOfIceAndFire''. Mostly because of the social belief that BeautyEqualsGoodness.
** Cersei Lannister was regarded as a dutiful and gracious leader before the rumours began flying about her {{Twincest}} with her brother, Jaime, and her eventual and obvious SanitySlippage.
** Joffrey as well, until he became [[TheCaligula King]]. Sansa later notes how he can go from being charming and polite, or 'playing the gallant' as she calls it, to [[HairTriggerTemper cruel and pissed off]] in an instant.
** The resident MagnificentBastard, Petyr "Littlefinger" Baelish. On the outside: [[ThePollyanna cheerful,]] PluckyComicRelief who is totally harmless due to his lack of status and amiable nature. On the inside...a DangerouslyGenreSavvy [[TheChessmaster Chessmaster]] with severe {{Yandere}}-tendencies who is responsible for [[spoiler: plunging an entire continent into a bloody civil war just to get back at the girl who rejected him.]] Yikes!
* ''Literature/SpocksWorld'' portrays [[spoiler: T'Pring]] as this. Outside, [[spoiler: she]] is extremely attractive. Inside, [[spoiler: she]] is behind much of the stirring up of the anti-human bile which is pushing Vulcan toward secession.
* Burgo Fitzgerald in ''Can You Forgive Her?" (1864) by Anthony Trollope. Trollope included many others in his other novels.
* Male example in ''Literature/TheGraveyardBook''. [[spoiler: Mr. Frost is the nice bachelor who has recently moved in. He is friendly to both Scarlet and her mother. Turns out, he's also the same Jack who killed Bod's family all those years ago, and is still out to get him.]]
* Several examples in ''Literature/WarriorCats''.
** Sasha meets some cats on a farm Pine shows her. They pretend to be nice, but as soon as Pine leaves, they attack Sasha and her kits.
** Hawkfrost acts kind and considerate, but really, he's a huge ass.
** [[spoiler: Ashfur]] is seemingly very nice, but he is consumed with hatred for [[spoiler: Squirrelflight. To the point of trying to kill her.]]
** [[spoiler: Hollyleaf, after ''Long Shadows'']]
** Sol. Calm, kind, [[MagnificentBastard behind everything?]]
** Willy and friends from ''Ravenpaw's Path''.
* Helen Vaughan in Creator/ArthurMachen's ''Literature/TheGreatGodPan'' appears to be a beautiful, charming woman. In reality, she's the HumanoidAbomination daughter of a dark nature god. She will seduce and lure you in, and drive you to madness and suicide.
* Dame Olga from ''Literature/EllaEnchanted''. When we first meet her, she seems nice enough, at least compared to her daughters (especially Hattie). But once she marries Ella's father and discovers that he had no money, she quickly turns into the cruel, abusive, petty stepmother we know from the Cinderella tale, making Ella a slave in her own home and tormenting the girl after her father leaves for business.
* Keifer Porter from ''Literature/ABrothersPrice''. He is mentioned to have been very pretty, if stupid, and only over the course of several chapters it is revealed that he was a villain, who was able to hide his monstrousness because his elder wives doted on him. At the start of the novel he is already dead, being [[spoiler: HoistByHisOwnPetard]]
* Nancy from ''Literature/AreYouThereGodItsMeMargaret'' She's nice enough to befriend Margaret, but mean enough to start vicious rumors about Laura Danker just because she has big boobs.
* Grandmother in Creator/LMMontgomery's ''Literature/JaneOfLanternHill''. She's a sweet-looking little old lady, but sabotages her daughter's marriage, and can, and does, make anything sound like an insult.
* The Literature/InDeath series: A number of the murderers can qualify as this. A notable example would be Ava from ''Strangers in Death''. Eve actually refers to the act Ava puts on as a suit, and Eve has to poke at it to eventually make Ava drop the act.
* Literature/SisterhoodSeries by Creator/FernMichaels: Rosemary Hershey was supposedly this, but by the book ''Sweet Revenge'', her little act has apparently worn thin. Little Fish, Stu Franklin, and Henry "Hank" Jellicoe are revealed to be this by the book ''Cross Roads''. The book ''Deja Vu'' simply expands on the depth of Jellicoe's depravity.
* Jeremy Jason [=McCole=] in ''Literature/{{Animorphs}}''. He seemed all nice and awesome on camera but was a total jerk off camera.
* Clive Barker's ''Literature/{{Abarat}}'' series contains a truly spectacular example, in the form of [[spoiler: Princess Boa]]. The world she comes from (yes, more or less the ''entire'' world) remembers her as someone who was inhumanly kind, innocent, and noble. ''Absolute Midnight'' reveals that, boy howdy, [[ManipulativeBastard she]] [[GrandTheftMe is]] [[TheChessmaster none]] [[AxCrazy of]] [[ItsAllAboutMe these]] [[GodSaveUsFromTheQueen things]].
* The [[spoiler:(impostor)]] Queen Vesper in ''Literature/FaeriesOfDreamdark''. And later, [[spoiler:Dusk, an old friend of TheHeroine's]].
* [[RomanticFalseLead Eliza Millward]] and Jane Wilson of ''Literature/TheTenantOfWildfellHall''. The former seems like a nice girl, and the latter is witty, alluring, and accomplished, but both turn out to be catty, spiteful bitches who enjoy MaliciousSlander of their romantic rival Helen Graham, a rather shy and reclusive woman who has fled DomesticAbuse. The latter is also a social-climbing GoldDigger.
* In the Literature/AgentPendergast novels we have Diogenes Pendergast. To one who doesn't know him (so pretty much anyone but his brother) he often initially pretends to be very sympathetic or one of the nicest guys on the planet... before leading his victims on to eventually brutally murder them or put them through severe mental damage. [[spoiler: And that's not even considering all the times he pretends to be ReasonableAuthorityFigure in the museum Hugo Menzies...]]
** There's also Captain Mason in ''Literature/TheWheelOfDarkness'': Second in command of the cruise ship the Britannia who always puts the well being of its passengers first and foremost. [[spoiler: You'd never think that she was a ruthless SerialKiller horrifically slaughtering those same passengers on your first glance.]]
* ''Literature/GalaxyOfFear'' has [[spoiler: Grimpen]], exploiting IJustWantToBeSpecial.
* Mercedes Cook of the Literature/KittyNorville series is this. When first introduced in ''Kitty and the Silver Bullet'' she appears to be a genuinely kind, funny, warm, and surprisingly human vampire who, once she's decided to "come out" to the public, has a candid and revealing interview on Kitty's show where she seems to be a kindred spirit, a great face for positive human-supernatural relations, and a possible ally. But after she invites Kitty over to her hotel room, only for it to turn out to be a set-up just to provoke a conflict between her and the antagonistic werewolves (her former alphas) who exiled her back in book one, [[BeneathTheMask she is revealed to be nothing like either her stage persona or how she appeared on the show]]--instead being a cold, manipulative, calculating creature whose motives are opaque and whose intentions are inscrutable. By the end of the book she's unequivocally a villain and major threat to be dealt with (or as Kitty puts it later, a "double-crossing fink"); as of book ten she's turned out to be a recruiting agent for and possibly TheDragon to the ultimate BigBad of the setting, Dux Bellorum.
* Barna, the leader of the Barnavites in the final ''Literature/AnnalsOfTheWesternShore'' book. He appears to be a jovial, charitable man of vision in the "free city" he founded in the forest. But it doesn't take long to show that he has a HairTriggerTemper, will fly into a killing rage when his authority is challenged, or if he catches you looking at a woman he has claimed, and treats women no better than livestock.
* ''Literature/TheReynardCycle'': Persephone's cousin, Celia Corvino. In public she's gracious, thoughtful and kind (and is considered a great beauty to boot.) Privately, she's [[spoiler:been plotting her cousin's death since she hit puberty.]]
* In ''Literature/CompanionsOfTheNight'', Ethan seems like a very nice guy when Kerry first meets him. It doesn’t last. As soon as she finds out that he ''truly is'' vampire, he drops the kindness act. [[spoiler: By the end of the story, [[DefrostingIceKing he does eventually become nicer to her though]], and a tad more honest.]]
* ''Literature/VampireAcademy'':
** [[spoiler:Victor Dashkov acts as surrogate family for Lissa and reportedly "had gone out of his way to help her after her parents died. He turns to be the BigBad]].
** [[spoiler:Natalie Dashkov acts like a cute and friendly dorky girl on the outside, which hides her true devious nature. She is not a true friend to Lissa, but an enemy. Killing animals, which Lissa cares for, in an effort to manipulate her. Leaving mental scars]].

[[folder: Live Action TV]]
* ''Series/BadGirls'' had Natalie Buxton. She was introduced to both the viewers and the other characters as a nice-as-pie, meek, timid woman who wasn't in jail for much of a crime. Turns out she's a peadophile with a tendency to beat the crap out of people if she doesn't get her own way. She eventually becomes the Top Dog because everybody is too scared to challenge her.
* One time ''Series/StarTrekTheNextGeneration'' character, Nicholas Locarno, while nice and charming on the outside, was actually a really nasty person beneath the surface, according to WordOfGod.
** Similarly, Khan seemed like a really swell guy, til he set out to kill Kirk, steal his ship, and conquer the known universe.
** The episode "Amok Time" gives us T'Pring. More of a bitch in EmotionlessGirl's clothing, really, but still the ex-wife from hell whose {{Jerkass}} moves include: provoke a situation knowing that she will get back at him and it will literally kill him (given the situation, her choices would be perfectly understandable if it was, even partly, for other motives, but it is apparently only for this), trying to make him fight his captain [[CrowningMomentOfHeartwarming and his friend]] to the death, then revealing that even if Spock still wanted her after all that, she would have cheated on him anyway.
* On ''Series/StarTrekDeepSpaceNine'', Vedek (later Kai) Winn: wise and benevolent religious leader on the outside, but full of biting, passive-aggressive insults that quickly reveal the depths of her envy and pettiness.
** Odo's former mentor, the Female Changeling, first appears in "The Search" as a wise, serene woman who is delighted that Odo has returned to his people. She and the other Founders are later revealed to be the rulers of the tyrannical Dominion. Throghout the series, we see examples of the malevolence behind her zen-like fascade, such as when she impersonates Kira, leads the Dominion occupation of Deep Space Nine, and orders the slaughter of the Cardassians at the end of season 7.
* ''Series/XenaWarriorPrincess'' features a few of these. Xena herself occasionally counts as this, especially during her first appearance on ''Series/HerculesTheLegendaryJourneys''.
** Gabrielle from Xena also counts as an extreme version of this in mid to late Season 5. Her bitchiness was so noticeable, out-of-character and unpopular, that it was actually lampshaded by Gabrielle herself in the episode "Eternal Bonds".
--> '''Gabrielle:''' ... I can be a real bitch sometimes, can't I?
** Also, taken UpToEleven by Varia. In every appearance she ever had, Varia was at first made out to be friendly, and as each episode panned out, she became the bitch yet again. Taken up again by yet ''another'' eleven by Varia in [[spoiler: "To Helicon and Back", which featured Varia selling Gabrielle out to a genocidal maniac, bent on the destruction of her people]]. Nice.
** Velasca wasn't very good at playing the sheep, but she also counts as this.
** Amarice in her first appearance was similar to Velasca, but was also more of a WellIntentionedExtremist, even trying to take on Xena, in her attempted protection of Gabrielle in "Endgame".
** Ephiny inverts this trope in her first appearance by being aggressive, unfriendly, and cold toward Xena and Gabrielle, before eventually becoming one of their best, and most trusted friends for the rest of her life.
* Jasmine from ''Series/{{Angel}}'' has a hypnotic power that causes everyone who sees her to instantly become entranced and view her as perfect and beautiful, which hides the fact that [[spoiler:her true appearance is of a decaying maggot-covered corpse, and she eats people. A lot. And wants to enslave the Earth.]] More to the point of the trope, while she acts like a wise and all-loving goddess when she's getting her way, an awful temper and vindictiveness lie beneath.
* ''Series/BuffyTheVampireSlayer'':
** Cordelia, in the first episode. She's very kind to Buffy and looks out for her on the first day, but Buffy sees her for what she is when she insults Willow for her admittedly hideous outfit. Cordy eventually redeems herself in both ''Buffy'' and ''Series/{{Angel}}'', but can still pull out the bitch card when needed as seen in "Rm w/a Vu"
** Whereas, by Season 7, one suspects that the reason Buffy spends ''every single scene'' with Spike is because no one else can stand her anymore. This is to the extent that the Scoobies and the Potentials get fed up with her bossiness, as well as having doubts over both her leadership skills and methods, and finally decide that Faith would be a better leader and kick her out.
*** The potential Slayers pick Faith over her. [[HeelFaceRevolvingDoor Faith]]. What's that tell you?
** Willow can be this occasionally, especially in season 6.
** Halfrek is a seemingly sweet-natured guidance counselor who is really a vengeance demon. Also, her insinuations against Xander to Anya.
* Speaking of Willow, Lily in ''Series/HowIMetYourMother''. She's manipulative and controlling and very rarely takes other peoples' feelings or opinions into account, but never gets called out on it. She appears to be the sweet, maternal member of the group but is revealed at one point to have been quietly manipulating her friends' lives and relationships for YEARS (going back to before the show began).
* This is how Dr. Kelso was introduced on ''Series/{{Scrubs}}''.
** He later turns out to be a JerkWithAHeartOfGold, especially after he retires.
** Elliot Reid is this in most, if not all, of her relationships.
* In an episode of ''Series/ICarly'', Carly meets up with an old friend named Missy, but Sam has suspicions that Missy is trying to get her out of the picture, but Carly believes otherwise. It turns out that Sam was right all along, and after winning a chance to take a cruise, Missy confesses to Sam about her intentions, but Carly was within ear-shot at the time, and [[spoiler:it also turns out that Freddie won the cruise and gave it to Missy, who [[LaserGuidedKarma is actually prone to seasickness.]]]]
* Marcy from ''Series/MarriedWithChildren'', who is often presented as being old fashioned and loving of her husband Steve (and later Jefferson). However, she often ends up in situations where someone has wronged her, and this often causes her to describe in violent detail how she is going to exact revenge on them. In a similar fashion, she's also shown to be sex-obsessed, but she tries to keep this persona hidden from the Bundys, because she wants to look wholesome and be the voice of reason. It never works.
%%* Dre from NoahsArc. It takes a full season for the bitchiness to reveal itself, but when it does...
%%* Sherry Palmer from ''Series/TwentyFour'' could've been the trope-namer.
%%** In all fairness, she did get a PetTheDog moment by helping Jack stop Peter Kingsley
* Isabella from ''Series/RobinHood'' shows her [[BeneathTheMask true colors]] when she tries to kill Robin after [[LoveMakesYouCrazy he dumps her]]. However, it is unintentionally subverted considering Robin's [[CharacterDerailment questionable behaviour]] in this particular season, and the fact that it is heavily hinted that Isabella has mental problems thanks to seventeen years of an abusive marriage. Likewise, the DerailingLoveInterests trope played a part, as Robin hooked up with [[CreatorsPet Kate]] soon afterwards.
** Kate herself was petty, mean, jealous, spiteful, and vindictive...not that the writers ever noticed, considering she was an almost too-perfect example of a JerkSue masquerading as a DesignatedHero.
%%* ''Series/EverybodyLovesRaymond'': In a flashback episode, Robert's ex-wife Joanne is revealed to have been one of these.
%%** Marie can also count as one as well.
%%** Debra also has her moments, particularly in the later seasons.
* ''Series/{{Friends}}'':
** One of Rachel's boyfriends (played by Creator/BenStiller) in season 3. He seems perfectly fine until someone or something pisses him off. Also Joey's first new roommate Janine who hate Chandler & Monica.
** Emily, Ross's 2nd ex-wife. Later on in her appearance, she became much more...not ''bitch'' per say, more along the lines of 'possessive extremist with a short temper'. Granted, she had reason for being not so innocent anymore ([[TooDumbToLive Ross said the wrong name at the wedding]]), but her 'demands' were admittedly quite unreasonable...
** Rachel also comes across like this, frequently manipulating Ross's girlfriends behind his back, forcing him to take all responsibility for their relationship problems and drawing all attention to herself.
** Phoebe, late in the series, especially in that episode where she and Monica try to break up and fire, respectively, a guy, but the first one to do so is the bitch. Monica rehires him but Phoebe doesn't take him back. She's also pretty horrible to Ross and Chandler (Monica's boyfriend and later husband) including introducing Monica to her "soulmate" while being well aware of Chandler's rampant insecurities.
* Amy Pond from ''Series/DoctorWho'' is something of an unintentional example. On the surface, she seems fun to be around, but she treats her boyfriend like ''crap''. She does get better, but trying to [[spoiler: seduce the Doctor the night before her wedding day, and attempting to kiss him on the day, was still a bit of a dick move.]] Though, it should be noted that, while she keeps bullying her husband for the whole series, later episodes make clear that she deeply loves him, to the point of not envisioning life without him.
** We get something of an inversion with Donna Noble. She starts out as a loud, shrill harpy, but as time goes on, we realize that her attitude comes from her feelings of total worthlessness. The Doctor said it the best, "Shouting at the world 'cos no-one's listening."
* ''Series/{{Firefly}}'' has Saffron/Yolanda/Bridget/[[IHaveManyNames whatever her real name is]]. A con artist with [[HighClassCallGirl Companion]] training who works by seducing anyone worth a mark.
%%* ''Series/SonnyWithAChance'': [[spoiler: Penelope]].
* In the KoreanSeries ''FortyNineDays'', In-Jung is the best friend of a girl in a coma. Come to find out, she set up the hostile takeover of her friend's company two years before the beginning of the story, using her boyfriend/lover as bait.
* Daphne from ''Series/{{Frasier}}'' is a rather [[PlayedForLaughs harmless and comedic]] example. While perfectly nice when she gets her way, she has also proven to be selfish, manipulative, petty, and [[HypocriticalHumor a huge hypocrite]] who is [[NeverMyFault quick to blame others for most of the problems she causes]]. This is actually lampshaded shortly after she gets together with Niles, when she believes that her overeating binge was caused partly by anxiety over the fact that she knows she's not as sweet as she acts and doesn't think she can live up to Niles's expectations of her after he has built her up and worshipped the ground beneath her feet during seven years of UnrequitedLove. [[HiddenDepths It turns out that Niles is perfectly capable of coming up with a long list of things he hates about Daphne, but loves her all the same.]]
%%* Becky Slater, Kevin Arnold's ex from ''TheWonderYears''.
* [[{{Series/Damages}} Patty Hewes]] seems to be invited to guest at a heck of a lot of morning news-and-chat shows in spite of her numerous nefarious, under-the-table deeds.
* On ''[[BeverlyHills90210 90210]]'', Naomi's older sister Jen seemed like she truly cared about Naomi in her first appearance. Right until we learn that she slept with Ethan while he and Naomi were together (she would later go on to sleep with Liam while he was dating Naomi and blame Annie for it).
** Annie and Dixon's cousin, Emily, seemed like a sweet, innocent girl who looked up to Annie at first. Then, she turned all of Annie's friends against her, tried to steal Liam away from her, and got Annie fired from her internship and suspended from school...all while pulling the WoundedGazelleGambit.
* Marisol from ''Series/{{Degrassi}}'' is [[BrainlessBeauty cute and cheerful (if a bit dim)]], however, she flirted with, and [[DidTheyOrDidntThey possibly had an affair with, KC]] while he was living with his girlfriend and [[TeenPregnancy son]], and told the entire school that her childhood best friend Katie was a recovering bulimic, almost causing Katie to relapse, all because Katie was dating Drew, who Marisol went on one date with months ago.
* HRH The Princess Eleanor from ''Series/ThePalace'' charms the public with her poise and charitable endeavours, but she's really a [[ManipulativeBastard ruthless schemer]] who will abuse anyone's trust to get to the throne.
* Morgana from ''Series/{{Merlin}}'' has fallen into this, mostly in the earlier seasons when she was pretending to be the good girl princess-her temper and strong will showed up from time to time, but Uther never knew she was as bad as she was. And she's openly evil nowadays. She wasn't really pretending to be good in the earlier seasons, she genuinely was kind-hearted, yet fiery when she needed to be. Since learning she had magic and resenting how magic-users are treated in Camelot, she turned against her old friends and became the evil villain she is now. Although, after turning to darkness, she did admittedly pretend to still be an ally of Camelot for a while, before dropping the ruse.
* In ''Series/{{Oz}}'', Schillinger offers to be Beecher's new cellmate to seemingly protect him from Adebisi. Beecher accepts the offer from the seemingly helpful Schillinger, but on their first night in the cell together Schillinger rapes Beecher and "brands" him by burning a swastika design into his right buttock.
* And let's hear it for Grace Whitney of ''DanceAcademy'': first she gets thrown out of the Royal Academy for driving another girl into a nervous breakdown; then she sets up Abigail (the only one who's even remotely onto her) as a villain to isolate her from her tentative friends Kat and Tara while also putting the moves on Abigail's choreographer Ethan and claiming he jumped her; she shows her true colours as a shameless and manipulative liar while rehearsing a 'self-revelation' choreography assignment, but still manages to convince everyone that she's a total sweetheart and 'the least competitive girl at the Academy'. Don't you believe it. Grace will do anything to get ahead.
* ''Series/{{Victorious}}'' had a girl named Ponnie, who pretends to be innocent and befriend Tori, but drives Tori insane because she claimed the moment Tori enrolled, Ponnie got kicked out. This is proven by Sikowitz to be untrue, but Ponnie still wrecks havoc.
* ''Series/TheMaryTylerMooreShow'' had Phyllis Lindstrom, and later Sue Ann Nivens, as mildly comic examples of this (making them perfect foils for the MinnesotaNice Mary.)
* ''Series/TheBigBangTheory'' has Emily, Penny's friend from a common yoga class. Feeling bad for Raj, unable to hold a girlfriend due to his embarrassing [[CuteMute selective mutism towards girls]], Penny and Howard try to hook him up with a sympathetic, funny and likeable deaf girl. While the plan seems to be successful, Emily soon reveals to be much less cute and lovingly as she seemed to be, [[GoldDigger pestering Raj for expensive gift and a lavish lifestyle]], ultimately [[spoiler: turning against him when her plan is discovered and Raj proposes her to live a more conservative lifestyle from then on]].
** On the show's main trope page, Raj's sister, Priya, is implied to be one as well.
* ''Series/PersonOfInterest'': This happens multiple times, in keeping with the central premise that the protagonists only receive the identity of a person ''involved'' with a murder-to-happen - whether it's the victim or the murderer is up to them to find out, with several "obvious" victims turning out to be either the perpetrators of the crime in question or guilty of other crimes. Specific examples (all three of them first season) include:
** [[spoiler:The prosecutor in the pilot. The guy stalking her is trying to uncover her crimes, her trying to find another witness is so he can be silenced and the obvious trap she's walking into is merely her meeting her associates.]]
** [[spoiler:Elias, the bogeyman of organized crime, plays the part of a school teacher who apparently has witnessed a murder and is now on a hit list. Reese protects him for most of the episode until Elias shows his true colours, cuffs Reese to a railing and escapes.]]
** [[spoiler:When we see Root in the season finale, she plays the part of a meek therapist who is being hunted down, giving no evidence of her true nature until we see her shoot a woman from behind and hold Finch up at gunpoint. Technically, she ''was'' the victim of the episode, but that was because she put a hit on herself so she could find the heroes who would come and rescue her.]]
* ''Series/{{Scandal}}'':
%%** First Lady Mellie Grant.
** [[spoiler: Becky, Huck's girlfriend]] turns out to this. No one could have ever suspected this person of shooting the President and framing Huck for it, or being such a murderous psycho in general.
* Alan Harper on TwoAndAHalfMen is the kind of guy who has spent his whole life living by an arbitrary morality, and is now mad that he hasn't reaped the rewards he thinks he deserves for it. Yes, [[ButtMonkey life hasn't treated him all that well]], but a lot of that is because Alan is a spineless doormat; he is incredibly resentful against his brother, who lived in hedonistic revelry that Alan secretly wanted himself, but never allowed himself to go for because he thought that the universe would automatically reward him for his passive aggressive nice guy act. In the last few seasons of the show, however, he seems to have realized this, and consequently has relinquished all pretenses of being a NiceGuy.
* Eva from Series/{{Awkward}}. When you first meet her, you'll think she's nice and hip, if a little pretentious. Then she'll start going after Matty and you'll realize she doesn't have a soul.
* Shirley Bennett in ''Series/{{Community}}'' tends to use a sugary-sweet personality and her devout religious beliefs to conceal and avoid dealing with her many personality flaws, including an extremely short and vicious temper, judgmental and hypocritical self-righteousness, mild racist beliefs and what is at times a very bitchy and nasty personality.

[[folder: Music]]
* In ''[[http://www.youtube.com/watch?v=1S7YxfZiJqM Flower of the Plateau]]'', [[{{vocaloid}} Mikulia]] is a florist [[spoiler: but she actually was an ex-prostitute who even ''kills'' two people, an ex-suitor/client and ''[[OffingTheOffspring her own son]]'' because they're the only ones who know that]].
* Progressive rock band Music/CoheedAndCambria makes a reference to this in their song "Welcome Home", with the "bitch" context taken a little up:
--> ''"A whore in sheep's clothing, fucking up all I do."''
** Debatable. Considering the song is about [[AxCrazy The Writer]] not only fantasising about killing his ex girlfriend, but also talking to his bicycle, [[UnreliableNarrator one wonders how much of The Writer's side of the story we should believe]].
** The song is featured in the rhythm game RockBand, where the same line is changed to "A wolf in sheep's clothing, mucking up all I do".
%%* The Music/ElvisPresley song, ''Devil In Disguise''.
* Referenced vaguely in Music/MumfordAndSons' "Little Lion Man".
--> ''"Your grace is wasted in your face. Your boldness stands alone among the wreck."''
* By {{Word of God}}dess, Music/SaraBareilles considers '''herself''' one of these. She's said at more than a few interviews that she finds it very amusing that she can fill her albums with angry songs that chew people out or tell people off, and people turn around and love her for it. In her words, "You can be a total bitch, but if you say it in a [[LyricalDissonance happy, peppy, sweet way]], absolutely no one will notice."
%%* The titular Christine in "Devil in Disguise (Chrstine's Tune)" by The Flying Burrito Brothers is made out to be one.
* "Down At The End Of Your Road" by Music/JethroTull, a ''Broadsword And The Beast'' era song describing a man who, by day, is a well respected real estate businessman, yet, by night, is a JerkAss who messes with the neighbors in various ways.

* From [[ClassicalMythology Greek Mythology]], Hera in pretty much all depictions. Queen of the Gods! Goddess of Marriage! Nice woman, right? Wrong.
** On balance, we are also shown that she's the victim of some [[ExtremeOmnisexual truly outrageous acts of adultery]] by her husband [[BrotherSisterIncest (and brother!)]], Zeus. That being said, there are times that Hera actually got things right, why don't you ask Medea on how it turns out for Jason betraying her marriage?
* Aphrodite is actually a better candidate. Arguably the UrExample of the BrainlessBeauty, and seemingly too innocent to perpetrate a single evil act. But she regularly runs the gamut from [[{{Jerkass}} petty and mean]] to pure evil. But just like Hera, there are also times that Aphrodite [[PetTheDog actually showed compassion]], but good luck spotting them in between her mean outbursts.
* Grimhild in NorseMythology. She made Sigurd forget about Brynhildr so that her own daughter Gudrun could marry Sigurd. This ends up getting both Brynhildr, Sigurd, Sigurd and Gudrun's son and Grimhild's youngest son killed. Then she forces her daughter to marry Brynhildr's brother despite that he may want to take kill Gudrun's brothers in revenge. Grimhild herself gets away.

[[folder:Newspaper Comics]]
* In ''ComicStrip/ForBetterOrForWorse'', when Elly is interviewing a replacement for Kourtney, she thinks the candidate seems like a nice person from her application, and wonders why she was let go. She calls up, and the woman on the other end seems polite up until she screams at her child for acting out. Elly politely removes her from consideration, having heard all she needs to.

[[folder: Professional Wrestling]]
* Wrestling/{{Maryse}}, in an angle with Wrestling/GailKim. She even began tag-teaming with (then-face) Gail, saying friendly things to her in English while [[BilingualBonus insulting her in French]]. ([[BilingualBackfire This backfired.]])
* Tina San Antonio feigned an injury to get out of Wrestling/{{WSU}} tag team championship defenses with Marti Belle so she could try out for Wrestling/{{WWE}}. She revealed this after relieving [[Wrestling/CarleneMoore Jazz]], who was acting in her place, and right before choking out Belle.

[[folder: Tabletop Games]]
* In ''TabletopGame/{{Exalted}}'', the [[http://forums.white-wolf.com/cs/blogs/freelancers/archive/2010/04/09/ink-monkeys-vol-10-black-claw-style.aspx Black Claw Style]] of Supernatural Martial Arts is based entirely around this concept; most of the techniques of the style are variations on the WoundedGazelleGambit, and the final Charm in the style is a powerful attack that becomes unblockable, undodgeable, and even more powerful if its target is someone who genuinely loves the user of the style.

[[folder: Video Games]]
* [[MonsterClown Dimentio]] from ''VideoGame/SuperPaperMario'' is a polite, almost perpetually-smiling court jester who pretends to be on the side of the heroes. [[spoiler:Then, he tries to destroy reality.]]
** [[PsychopathicManchild Mimi]] also fits this trope, although she drops the "nice" facade within a few minutes of meeting Mario (when he breaks her vase). The player knows she's evil from the get go, though, [[spoiler:and she pulls a HeelFaceTurn at the end.]]
** And in ''VideoGame/PaperMarioTheThousandYearDoor'', there's [[spoiler:Grubba]], who acts nice to Mario for most of the chapter, [[spoiler:but turns out to be a total bastard who's been using the chapter's MacGuffin to drain the life energy out of people later.]]
* Nur-Ab-Sal from ''VideoGame/IndianaJonesAndTheFateOfAtlantis'' is the spirit of an Atlantian king who Sophia claims as her spirit guide. Indy, as a scientist and a cynic, is less inclined to buy into the mumbo-jumbo of the spirit world... though, through his guidance of Sophia and various displays, Nur-Ab-Sal proves to be quite real on more than one occasion... [[spoiler: Real, really controlling, and really bad news. You initially think that Sophia is just protective of her necklace because she refuses to trade it or remove it, but gradually, with the right dialogue--especially in the team version--you realize that it's Nur-Ab-Sal who's possessive of Sophia. Upon reaching his "throne room" in Atlantis, he finally fully reveals his true colors by possessing her completely, claiming to Indy that the time for human frailty has passed, and dooming her to die there as his vessel.]]
%%* [=GLaDOS=] from ''VideoGame/{{Portal}}''.
%%** [[spoiler: Wheatley]] from the second game is one as well.
* Yokuba/[[MeaningfulName Fassad]] from ''VideoGame/{{Mother 3}}''.
* Franchise/{{Halo}}'s [[DarkMessiah Prophet of Truth]] comes across as polite and affable at first to the [[ScaryDogmaticAliens Covenant]], until it's shown that he tried to commit Genocide against the Elites, and he becomes hysterical by the end of ''VideoGame/{{Halo 3}}''.
* Atris, from the second ''VideoGame/KnightsOfTheOldRepublic''. She even wears white. Despite her [[GoodIsNotNice crappy attitude]], she presents herself as very much holier than thou; the quintessential perfect goody-two-shoes Jedi. In reality, she has turned to the dark side and caused countless innocent deaths. ExecutiveMeddling caused the extent of her evil acts ([[spoiler:causing the destruction of Katarr, the extinction of the Miraluka, and the death of hundreds of Jedi just because she loved and hated the Exile]]) to be cut from the finished game. If anything, she's a unique case in that she has no idea how bad she was until she's shown.
* In the beginning of ''VideoGame/DragonAgeOrigins'', Queen Anora seems like nothing but eye candy for [[UpperClassTwit King Cailan]], and, after his death, became the justification why her father should be the regent in the absence of a king. Towards the end of the game, you have to [[DamselInDistress rescue her from a castle where she is kept against her will by her father]]. Once you have saved her, it turns out that she had been running the kingdom all the time. That her father arranged for the death of her husband seems not to be bothering her too much, but she isn't going to let him take away ''her'' kingdom. She agrees to marry her late husband's half-brother to strengthen her claim as the queen, but only under the condition that she keeps running the show and ''he'' is going to be only for show.
** Sister Petrice plays one in ''VideoGame/DragonAgeII'' as she manipulates events in order to start a war with the Qunari.
** In ''Videogame/DragonAgeInquisition'', Empress Celene of Orlais is always courteous to the Inquisitor and projects the image of a peaceful High Queen. The prequel novel ''Literature/TheMaskedEmpire'' shows that she's a scheming manipulator who makes ''Anora'' look nice. She justifies her actions as being for the good of the Empire, but [[spoiler:murdering thousands of her subjects [[FantasticRacism (all elves)]] just to keep them from being used by a rival]] is not the kind of plan a good person would even consider, let alone put into action. Neither is [[spoiler:faking an assassination attempt on herself, a farce that caused the deaths of all her servants, including her lover Briala's parents.]] While none of the potential candidates the Inquisitor can support to rule Orlais are wholly good people, Celene is arguably the most morally repugnant of them all judging by her actions. But she's always very polite.
* ''VideoGame/BaldursGate'': Aerie comes across as the sweet, innocent [[TheWoobie Woobie]] of the group for most of the story, but gods help anyone in a romantic rivalry with her. It's telling that Jaheira, whose status as a short-tempered {{Tsundere}} is the stuff of legend, has the clear moral high ground when the two of them fight over a male player character.
* ''VideoGame/{{Darkstalkers}}'': B.B. Hood/Bulleta. Well, hopefully. If it's ''not'' just an act, she's even more AxCrazy than she seems, which is saying a lot.
* Athena in the ''VideoGame/GodOfWar'' series. She plays TheObiWan role for most of the first game, [[spoiler:and in the third, though posthumously, only to reveal her true nature after Zeus is killed. When Kratos sacrifices himself to release Hope to all of humanity, Athena wails, "You fool! That was supposed to go to '''me!''' The mortals won't know what to do with it!"]]
** Actually it's implied that this was ''God of War III'' only. The box's evils infected the others so it may have influenced her as well. She also states that becoming a ghost caused her to "see the bigger picture" so it's quite possible that she only fell prey after death and may have genuinely cared about him in games one and two. Hell Zeus himself flat out states she refused to betray him.
* [[spoiler:Adachi Tohru]] in ''VideoGame/{{Persona 4}}'', in the Normal/True playthrough.
** [[spoiler:Izanami]] might be a more subtle example. [[spoiler:She's a goddess who gives people incredible power and sits back as two of them endanger the lives of innocent people, and ultimately ends up trying to kill you.]] Her disguise? [[spoiler:An androgynous, and relatively friendly gas station attendant.]]
** [[spoiler:Ikutsuki]] in ''VideoGame/{{Persona 3}}''.
* [[spoiler: Scott Selby]] in ''VideoGame/HeavyRain''. At first [[spoiler: he]] comes across as a nice, compassionate [[spoiler: guy]], who even [[spoiler: rescues a suicidal mother and looks after her baby]], but [[spoiler: is actually the Origami Killer]].
* [[spoiler: Fal]] from ''SymphonicRain'' who only acts nice to the protagonist in order to take advantage of his musical talents.
* [[spoiler: Paz]] from ''VideoGame/MetalGearSolidPeaceWalker''. She introduces herself as a sweet college student longing for peace in her beloved country, Costa Rica. Even after knowing that her "professor" works for the KGB, Snake decides to accept the mission just for the sake of this girl, because he thought that her feelings were genuine. [[spoiler: But then she turns out to be the game's final boss when she steals YOUR beloved Metal Gear ZEKE, pilots the damn thing in ''[[RuleOfSexy her underwear]]'', and tries to blast you with a railgun. She actually works as triple agent for the KGB, CIA, and mostly Cipher the proto-PATRIOT. Thank God Snake then blows her ass out of the Metal Gear, into the ocean.]]
** [[spoiler: Her actions also serve as a testament to how far Zero and the Patriots have fallen in the past ten years, as its revealed that she was scared to death of failing them and considered inciting their wrath a FateWorseThanDeath; indeed, her diaries reveal that she actually [[BecomingTheMask Became The Mask]] to an extent and wished she didn't have to do what she did.]]
* Given the lighthearted nature of the series, [[CuteMonsterGirl Pamela]] from ''Franchise/{{Atelier}}'' is a PlayedForLaughs case. Well, she's not evil, but some things she does are not very...nice.
** In Trinity Universe, she more or less states that she does those things only because that's how ghosts are supposed to behave. She genuinely is dense to the point that she doesn't realize what she does can be construed as 'evil', and all she really wants is a friend to play pranks on. Even when she goes ubercreepy and helpfully hopes you'll die soon, it's only because she thinks that way you can have fun being ghosts together with her.
* [[spoiler: Mary]] from VideoGame/{{Ib}} is one. At first, she appears to be a visitor that became lost in the art gallery like Garry and Ib, but [[spoiler:she's actually a living painting who is willing to trap them there so that she'll be able to escape to the real world.]]
* Numnu from ''VideoGame/SuikodenTierkreis'', although this is usually PlayedForLaughs. He might seem to be a cuddly, adorable [[FishPeople Porpos-kin]], but he is also good at putting people into troublesome, or even outright dangerous, situations.
* [[spoiler: Levin, aka the third World Eater Raksha,]] from ''VideoGame/SoulNomadAndTheWorldEaters'' combines this with ObfuscatingStupidity and spends most of the game pretending to be a good-natured goofy moron. Disturbingly enough, while he isn't good-natured or moronic in the slightest, he still comes across as a little goofy [[spoiler: when Trish confronts him]]. This is also one of the rare cases where, depending on RelationshipValues, the person in sheep's clothing can end up BecomingTheMask.
* ''VideoGame/DragonQuestIX'' has Mayor Bryce, who runs the struggling Port Llaffan. While he treats Jona kindly, acting like a surrogate father for the recently orphaned girl, he's mainly interested in abusing her ability to summon the great whale, Leviathan. When she says that she's not comfortable overusing that power, he immediately replies, "Well, it's not like you can do anything ''else'' for us, useless girl." It's not simply a matter of helping their village survive, either; he keeps her summoning to the point where everyone completely abandons their fishing as useless. And even before she developed her power, when they were honestly struggling to survive, he ''still'' wouldn't let anyone else use his private fishing hole...better described as an entire ''coastline''.
* Randy from ''VideoGame/ValkyriaChroniclesII'' qualifies. He's the ideal student council president, comforting those who are down and out and helping old ladies across the street. And then you bring him into battle...BANG BANG BANG PLOP. [[SarcasmMode "How unfortunate."]] The whole nice guy thing was just a facade so that he could set himself up for a leadership role. God help you if he perceives you as a threat to his role as a leader and the center of attention.
* In ''VideoGame/WorldOfWarcraft Cataclysm'', it turns out that Hope Saldean, the kindly adopted daughter of the Saldean farmers who cares for the people of Westfall, is actually Vanessa [=VanCleef=], who seeks to revive the Defias Brotherhood and avenge her father's death.
* Captain Shannon from ''VideoGame/TheOrionConspiracy''. He seems to be a nice guy, giving a eulogy to Danny, Devlin's son, and letting Devlin say something at the funeral. He seems to care very much about the crew (notwithstanding some hostilities between him and the engineer Meyer), and is a little condescending towards Devlin, on the grounds that Devlin is middle-aged and Shannon is in his prime. Shannon also seems to be rather anal about the rules. Then, when [[spoiler: Kaufmann]] is murdered, Shannon blames Devlin for the murder, ignores Devlin's protests of innocence, has Devlin imprisoned, and decides to cover up the murder, keeping it between himself, [=LaPaz=], and Ward. So you would think, what a sleazy guy, right? Then Devlin and Shannon have a confrontation later on and it is revealed that [[spoiler: Shannon blames Devlin for the death of Shannon's wife, so he murdered Danny as part of his revenge, then he murdered Kaufmann to frame Devlin, and now he is going to murder Devlin]]. Now ''that'' is a [[BitchInSheepsClothing Bastard In Sheep's Clothing]]! Good thing [[spoiler: Meyer]] intervened before anything else happened.
* Luca from ''VideoGame/ArTonelico2'', she gets better, but [[TheScrappy there are still people who hate her for it.]]
** Harvestasha in the sequel, very {{Moe}} in an appearance and has a very squishy voice, but doesn't hesitate in disabling her trusted friend in an attempt to wake up a PhysicalGod.
* James Tobin from ''VideoGame/InThe1stDegree''. He seems like a nice guy who got caught in a bad situation at first. However, it will become clear that this is only the image he is trying to project, as he is trying to not be found guilty of murder and grand theft. Luckily, he is not very good at projecting this image. In fact, if you play the game right, you'll be able to make him lose his cool completely, and then he will show himself for what he is right in front of everybody in the courtroom.
* [[spoiler: Jeannie May]] in ''VideoGame/FalloutNewVegas'', who gets found out during a quest to find out who [[spoiler: sold Boone's wife to Legion slavers to have her lead out to be assassinated in front of the local tourist attraction, later]], and nothing of value was lost.
* ''VideoGame/TheLegendOfZeldaTheWindWaker'': Tingle is perky, cheerful, and near-sycophantic when talking to Link, but if you talk to the guy in pink, he reveals that he's Tingle's younger brother, and Tingle is incredibly abusive, but on days when you visit, he's so much nicer (he does not, however, specify if "so much nicer" is enough of an improvement for Tingle's behavior to qualify as "nice" on its own)! If you talk to the guy in white, you find out ''he's'' not even related to Tingle; he's just some poor schmuck who happens to look like Tingle, and washed ashore one day after a boating accident, and Tingle has been forcing him to do menial labor ever since.
* Prince Fleaswallow from ''VideoGame/PaRappaTheRapper'' seems like a normal, but eccentric shopkeep obsessed with love at the local flea market. However, if you actually pay attention to his lyrics, he seems to [[AGodAmI have a god complex]], [[JustGotOutOfJail be on the run from the police]], and [[MoneyDearBoy only cares about making money]]. It's also implied the merchandise he sells is stolen, and that he'd be willing to steal someone's ''entire business''.
* In ''VideoGame/{{Disciples}}'' ''2'', Uther first appears as TheChosenOne who will save the Empire from ruin. The first hint that he's not the MessianicArchetype is the way he cruelly mocks the Dwarven King's grief over his lost son. During his coronation, Uther drops all pretense by murdering his father the Emperor with hellfire and summoning demons in the heart of the capital. He then reveals his true demonic form and his goal: to conquer Hell itself.
* ''VideoGame/TheWitchsHouse'', Ellen, [[spoiler:especially in Viola's body. She used Viola to get her body, tortured her by having her legs cut off and eyes gouged out and gave a powder to hurt her further, killed a frog after it helped her and its tadpoles, and, worse of all, laughed at Viola after her own father killed her/]]
* [[spoiler: Maya Brooks, the goofy, jovial, friendly Alliance Staff Analyst]] from the Citadel DLC for ''VideoGame/MassEffect3'', as it turns out, was [[spoiler: an ex-Cerberus officer who left the group out of disgust [[FantasticRacism because the Illusive Man had started looking to non-humans for help]]. She also was the one who orchestrated the mercenary ambush in the Wards to intercept Shepard's Spectre code and the one who killed Khan. She was working with Shepard's clone in an attempt to steal Shepard's identity, and, after leading Shepard and their party into a trap, leaves them to suffocate to death in an iridium vault. At the end of the DLC, she shows that she doesn't even have any loyalty to Shepard's clone, as she leaves them to their death as well. She at first appears to be one of the nicest characters in the series, but ends up being one of it's most heinous.]]
* ''VideoGame/LastWindow'' has [[spoiler: Dylan Fitchar]] who may come off as a bit of a NosyNeighbor, but is generally normal. In actuality, [[spoiler:he's TheMole for Nile.]]
* Tsubaki Yayoi of ''VideoGame/BlazBlue''... Eh, sort of. Her polite, prim and dutiful nature is genuine, but she secretly harbours an [[{{Yandere}} unhealthy attraction to Jin]] and it occasionally leads to some [[GreenEyedMonster startling]] [[MurderTheHypotenuse behaviour]]. She's too three-dimensional to openly call her a bitch or a nice gal, but she has qualities of both.
* {{Transistor}}'s Sybil Reisz has this as one of her few given personality traits, apart from her [[VillainousCrush massive crush]] on Red.
* Even though Joshua from ''VideoGame/TheWorldEndsWithYou'' seemed like a rude little snot, he also looked like a generally nice guy. Even going as far as to [[spoiler: "Sacrifice" himself for Neku]] He just seemed like a nice, slightly lonely kid... He wasn't. [[spoiler: He was secretly the Composer, who had been using Neku THE WHOLE TIME, and was fully intending to destroy Shibuya. Oh, and that sacrifice I mentioned earlier? All part of his plan]]
* In the near-endgame of ''VideoGame/{{Bravely Default}}'', it's revealed that [[spoiler:Airy was working for the main antagonist of the game, and was following the party in order to convince them to purify the crystals, which would infact do the exact opposite of saving the world, which is what Airy had been telling the party.]]

[[folder:Visual Novels]]
* Many characters in the ''Franchise/AceAttorney'' games are like this, and they're usually the true culprit of the crime.
** [[spoiler: Dahlia Hawthorne being the best example, since she looked [[TastesLikeDiabetes sweet enough to give one cavities]], but was, in actual fact, a bitter serial killer.]]
** ''Apollo Justice'' also had [[spoiler: Alita Tiala, a seemingly loving, devoted fiancée to Wocky, the defendant of Case 2, who was, in fact, marrying him because she and the victim of the case were the only two people who knew that Wocky was going to be dead soon. In fact, she carried out the murder to prevent being ratted out, and blamed it on Wocky.]]
** [[spoiler: Matt Engarde]] is a pretty decent male example.
** As is [[spoiler: Kristoph Gavin]].
** Subverted in T&T case 2, where everyone expects this of Desiree, but she's genuinely a nice person.
** And deliberately invoked in Investigations. [[spoiler: Colias Palaeno was designed to be as friendly and sweet as possible to make veteran players suspect him right off the bat. In fact, he's exactly who he presents himself to be, and was just Manny Coachen's pawn.]]
* To first time players of ''VisualNovel/SuperDanganRonpa2'', Hiyoko Saionji's [[OlderThanTheyLook childlike appearance and attitude]] during her introduction would most likely come off as adorable and some would even think she's going to be a sweetheart. That thought is ultimately crushed only seconds later when she reveals that she's laughing because she's playing with ants and likes the "pop" noise that happens when you crush them, and then snickers evilly and calls you a coward when you refuse to join her. [[FromBadtoWorse Her personality and habits just get worse from there,]] but her cute appearance never changes.
* Tokimi in ''VisualNovel/EienNoAselia''. Only Yuuto ever seems to realize it. Deep down, she's really not so bad, though.
* Borderline example: Rin Tohsaka from ''VisualNovel/FateStayNight'', who combines this with JerkWithAHeartOfGold. She's not a bad person, but she's [[TallDarkAndSnarky Cool, Dark and Snarky]], rather than the "perfect honour student" image she shows to the rest of the school. The only ones in on her in on her real personality (barring [[TheHero Shirou]], who's a bit traumatised when he finds out) are her [[TheRival rival]] Ayako, who has a similar facade going on, and Issei, who served with her on the student council in middle-school and got to see her true, pragmatically ruthless nature. Sakura seems to have at least some idea too, [[spoiler:because she's her sister]]. She has rather mixed feelings, however, since she [[spoiler:worries about what Rin might do to Shirou in the war, but at the same time, clearly still loves Rin, and desperately wants to be acknowledged by her.]] How much of this you see depends on the route. In Fate, you see some of her kindness amongst her glorious snarkiness. In Unlimited Blade Works, her kindness is fully displayed. In Heaven's Feel, [[spoiler:she ''seems'' to drop the 'heart of gold' entirely and just becomes a bitch -- especially towards her sister, Sakura -- until the end of the final fight, where she [[CrowningMomentOfHeartwarming demonstrates that]] her bitchiness had really been a facade all along, as an attempt to persuade herself that she could, after all, [[ShootTheDog kill]] [[WoobieDestroyerOfWorlds Sakura]] if she had to]]. The True End of the Heaven's Feel route implies that she has dropped the "bitch" part entirely, at least as far as [[spoiler:Sakura and Shirou]] are concerned.
* Chiaki in ''VisualNovel/OurTwoBedroomStory'' is described as "gentlemanly" and having a "sweet face," and he exerts himself to come across as pleasant and cheerful to his co-workers. However, as the protagonist soon discovers, his true self is something less pleasant - though not unredeemably so, given that he's one of the possible love interests of the game.
* Jeff from ''VideoGame/{{Nicole}}'' is a mild example: due to [[spoiler:not wanting to be a burden on his grandparents after his mother abandoned him with them]], he has created his persona based on what the majority of the population wants to see, which is an all-around nice guy who excels at what he does and is helpful and friendly. In truth, he's a bit off his rocker, distant, has almost no empathy for others, and generally considers everyone around him complete idiots, but he's not actively malicious. Like Chiaki above, he's not presented irredeemable, and he's a potential LoveInterest. [[spoiler:That being said, he becomes a ''far'' less mild and more malicious version when you find out that he's behind the recent kidnapping of three women -- even then, he's still redeemable, but ''only'' if he's Nicole's chosen LoveInterest. Otherwise, he remains a SmugSnake who views others as subhuman]].
* The waitress in ''VisualNovel/GrisaiaNoRakuen'' that married Robbie and waits on Yumiko is rude, passive aggressive and pushy despite her superficial politeness. [[spoiler:As a CIA agent that's usually much more stoic, she's probably pissed at the cover job she has to take.]]

[[folder:Web Comics]]
* ''Webcomic/VampireCheerleaders'': Heather may have seemed sweet and innocent, but it didn't take much for her to reveal her true colors, and it didn't take long either. All she needed was [[EvilFeelsGood a taste of power.]] After choosing to become a vampire, she [[http://www.vampirecheerleaders.net/strips-vc/meet_the_parents_3 turned on]] [[http://www.vampirecheerleaders.net/strips-vc/meet_the_parents_4 her own parents]]; reducing them to being [[http://www.vampirecheerleaders.net/strips-vc/heather_gets_a_baby_sister her mindless slaves.]]
* Zola, in ''Webcomic/GirlGenius'', seems to be an innocent, rather ditzy pawn of high-ranking plotters, but she's really [[spoiler:a calculating villain, fully aware of what she's involved in, and possibly the biggest threat Agatha faces]].
* ''Webcomic/{{Drowtales}}'': Snadhya'Rune comes across as a ditzy Napoleon Bonaparte; power-hungry but willing to aid the common masses in exchange for her absolute rule. Basically, she states her liberal-idealist intentions and has every possible threat to her rule slowly obliterated through war, betrayal, and propaganda. Until the ''clusterfuck'' that is Chapter 46: [[spoiler:After being injured for the first time ever in the comic, she breaks the masquerade and freaks the fuck out, murdering everyone within a ten yard radius. And may have destroyed her castle in a fit of rage if not for Mel's intervention. Later, her firstborn daughter Kalki is busy trying to use the airship to lay waste to Ariel's squad. She proceeds to destroy Kalki's physical body by using a magical grenade that manifests as ripper hands. And call her a faulty tool]]. Hemophobic ''bitch'' is an understatement.

[[folder:Web Original]]
* In ''Roleplay/TheGamersAlliance'', Desdemona and [[spoiler:Vaetris]] seem genuinely nice and likable people but underneath that kind exterior they're anything but. The former is actually a power-hungry, backstabbing schemer who killed one of the heroes and is currently manipulating King Marcus into marrying her in order to subtly take over the Remonian throne, and the latter is one of the four dreaded archdemons in disguise whose goal is to keep other races divided so that she can take over the world with her demon horde.
* WebVideo/TheNostalgiaChick combined this with a SarahPalin impression to try and [[TheStarscream overthrow]] the Critic during WebVideo/{{Kickassia}}.
** To a less homicidal extent, how she is normally. [[ComedicSociopathy There's]] [[ManipulativeBastard something]] [[BrokenBird darker]] underneath that [[GirlishPigtails cute]], [[BowtiesAreCool girly]] [[HairDecorations exterior]].
* In the Travel Channel website-original animation "[[NoReservations Anthony Bourdain's]] Alternative Universe", we see a fictional side of travel hostess Samantha Brown we don't normally see on the air, in the episode [[http://www.travelchannel.com/Video/following-the-footsteps-of-frankenstein-11695 "Romanian Rhapsody"]] (Sam's segment starts at the 1:40 mark). Seeing the burned corpse of the fictional Anthony Bourdain, she goes, "Yeah, NOW who's laughing, funny man?" Sam kicks the head off the body, then gets an evil look on her face as she goes, "Guess that 10:00 time slot [[PunctuatedForEmphasis just. became. AVAILABLE.]]" Spouting off to a nearby camera man, she tells him when she's calmer, "Go get the head and send it to Creator/{{Rachael|Ray}}. She'll appreciate it." One final rant, and then she gets the clapboard in front of her face. Once the clapper comes down, she's her normal smiling self again.
* ''Roleplay/SurvivalOfTheFittest'' v4 has Aaron Hughes as a male example. He starts out wanting to start an escape plot, but throughout the game, he {{manipulat|iveBastard}}e every single character he comes across, and eventually decides to play the game conventionally while still keeping the guise of the leader in an escape plot. Ashlie Jackson of ''Evolution'' is also hinted to have been one of these before being put in the experiments, and although her power rendered her unable to pull it off as much, she attempts to pull off a CuteMute facade at one point. And as early as his first appearance, Simon Leroy of ''Virtua'' is already shaping up to be a male example, who started out the game attempting to get [[ShrinkingViolet Sycanus Appletin]]'s trust by pretending to be a NiceGuy...while planning to [[ManipulativeBastard use her trust to his advantage]].
* Solange of the Literature/WhateleyUniverse started out this way. As a frosh, she was kind and understanding to Montana even though he looked like a sasquatch... and then she publicly humiliated him. All so she could force her way into the top clique of the school.
* [[http://akaichounokoe.deviantart.com/gallery/?q=paper+#/d4z3yme Toki is kind and gentle to some but bitchy to others]] Actually, make that abusive
* This article of [[http://www.heartless-bitches.com/rants/niceguys/niceguys.shtml [=HearlessBitches.com=]]] is a rant about the EntitledToHaveYou sort of person.
* Esmeralda on ''WebOriginal/TheWarComms'' is a variation; rather than everyone thinking she was gentle and sweet they thought she was too passive and whiny to do any real damage. The "sweet and proper lady" image was her own insistence, even as her claws started coming out...[[http://fandomwar.dreamwidth.org/1855.html?thread=128319#cmt128319 and then this happened]].

[[folder:Western Animation]]
* Angelica Pickles in earlier episodes of ''WesternAnimation/{{Rugrats}}'', while seemingly polite and sweet to adults, is actually a SpoiledBrat and a ControlFreak who constantly [[KickTheDog abuses her baby cousin]] and his friends. She was mostly this in the first season.
* Darla Dimple in ''WesternAnimation/CatsDontDance'' has a reputation as "America's sweetheart lover of children and animals," but in reality, she's a SpoiledBrat who hates animals and absolutely cannot ''tolerate'' the thought of them stealing any limelight from her.
* Suzy Johnson on ''WesternAnimation/PhineasAndFerb'', though possibly only when it comes to girls her older brother Jeremy likes (and whom she thus feels are a threat to her status as his "favorite girl").
** Apparently, she also torments [[TheBully Buford]], but the audience has never seen her do it.
* Subverted in ''WesternAnimation/TheFairlyOddParents'', where Timmy summons a pop star for his babysitter to forcibly marry, expecting that he will be an example of this trope...however, he turns out to be a very nice and easygoing guy.
** Played straight with Vicky. She acts nice and gentle in front of Timmy's parents... but when they're not around, she's a heartless, evil bitch who constantly goes above and beyond to make Timmy's life a living hell, and the very reason why Timmy is miserable enough to have fairy god parents in the first place.
* On ''WesternAnimation/{{Futurama}}'', Leela dates the Mayor's Aide, and he pulls strings to get her nice perks, before discovering that he was a creep who deprives orphans of fun and commits other such selfish acts to get those perks.
** Also Mom, the grandmotherly industrialist who is secretly a bitter, old hag.
** And Zapp Brannigan, of course. ''The'' Zapp Brannigan!
*** Then again, it has more to do with just about ''everyone's'' inability to recognize Zapp's incompetence.
** Also Professor Farnsworth. Considering that some of the less disruptive things he's done in the show include creating albino atomic apes for the sole purpose of proclaiming his love for Mom, and the implication that he has multiple doomsday devices, his charming and harmless-seeming senility [[AlternateCharacterInterpretation could be]] just [[ObfuscatingStupidity a very good act]].
* Lois in ''WesternAnimation/FamilyGuy'' definitely falls here in the episodes where David Zuckerman isn't involved. Granted, she is a sensible person and the usual voice of reason, but really get her going and she can do some rather questionable things and not bat an eyelash. Can't even get the courage up to say "I Love You" to her daughter [[ButtMonkey Meg]] (she merely mumbles it) on her ''wedding day, no less''.
** Even lampshaded in one episode where she is described as "more of a bitch than she lets on."
** Goes even further in the 'Foxy Lady' episode when Peter draws Red Heinie Monkey's female sidekick "who's always nagging at Red Heinie Monkey and telling him not to leave his beer cans lying around and what not."
-->'''Peter''': [Holding up a drawn picture of Lois with a duck bill instead of a mouth and nose] And her name is Bitch-Duck.
-->'''Meg''': That kind of looks like Mom.
-->'''Peter''': Not finished talking, Meg!
** Most formerly pleasant characters or StraightMan types have gained extreme JerkAss traits that makes them into this trope. The frequent ComedicSociopathy in the show has arguably lent to the more openly JerkAss characters, like Stewie, actually having more genuine redeeming aspects than the {{designated|Hero}} "nice" ones, such as Lois.
** The [[TastesLikeDiabetes undoubtedly overly sweet New Brian]] bonded with the family so well that he seemed to be a perfect replacement for Brian until Stewie found out something incredibly dark about New Brian; the dog humped Stewie's teddy bear, Rupert, and New Brian rubs salt in the wound by saying that every time Stewie holds Rupert, the bear will think of New Brian instead (and this is complete with a smug grin). Stewie proceeds to kill him, chop him into little pieces, and toss the body in the garbage.
** Bonnie counts here as well. In "Go Stewie Go" she admitted to Lois that she cheated on Joe before, and encouraged her to do so as well instead of talking to Peter about how him calling Lois old was hurting her feelings. She attempted to cheat on Joe again in "Foreign Affairs", but was stopped by Lois bringing Joe there to stop her. [[DoubleStandard Then she acts like such a betrayed victim when, after acting cold and indifferent to Joe, he cheats on her.]] And in "And I'm Joyce Kinney" when Joyce Kinney reveals in her news broadcast that Lois had done a porno, Bonnie immediately runs over to the Griffin house to point at Lois and call her a slut.
** When Chris dates a girl with Down Syndrome, she appears to be nice, but Chris finds out later on that she's a controlling and stuck up bitch that expects her date to do everything for her. Chris finally snaps and calls her out on it.
* Francine of ''WesternAnimation/AmericanDad'' also occasionally leans into this (or BewareTheNiceOnes on lighter occasions), though, granted, she is [[WhatTheHellHero called out on it]] or handed an Aesop more often than Lois.
** Watching a few Christmas episodes will show you [[spoiler: Santa Claus]]. Still thinking of the Jolly Ol' Saint Nick, aren't we? The few episodes he appears in will show that this version of the character is definitely not so jolly.
* Ferris Boyle from ''WesternAnimation/BatmanTheAnimatedSeries'' episode "Heart of Ice." While he pretends to be a humanitarian, he is really a callous monster who cares only about money. Even Batman, who's usually pretty stoic, is horrified to the point of even muttering an audible "My God!" (an EXTREME rarity in cartoons in those days), when he discovers the full extent of what Boyle did. The only happy part in the whole episode is knowing that Boyle will face justice for his crimes thanks to Batman.
* Quite a few characters on ''WesternAnimation/TheVentureBrothers'' can be this from time-to-time, but nobody takes the cake like Dr. Jonas Venture. When the show started, he was just shown as a God-like super-scientist and globetrotting adventurer who was just plain better than his son and heir, Rusty. But as the show went on, it was revealed that he was an extreme {{Jerkass}} who went back and forth between neglecting his son and putting him in situations of traumatizingly-high levels of danger. Further, the reason Rusty is such a failure who can't live up to his dad is because of his horrible upbringing which has left him a mental wreck.
** Rusty's brother Jonas Venture, Jr. seemed like [[AlwaysSomeoneBetter a nearly-perfect human being]] when he first emerged from Rusty's body. Only gradually was he revealed as a lousy husband and all-around self-involved jerk.
* In ''WesternAnimation/CodenameKidsNextDoor'', Numbuh 3's little sister Mushi, at first, comes across as being just as childish and ditzy as her older sister. However, when she is stuck alone on the space ship with Cree and Numbuh 5, she gives a speech about how they should stop fighting because sisters are supposed to care about each other and be friends. As the teenage villain stops to think about this, the little girl pushes her out of the airlock, turns to Abby, and says "older sisters always fall for that mushy stuff". In her next appearance, her [[BeneathTheMask true colors]] are revealed as she stabs her sister's stuffed animal and is sent to her room forever. After that, she becomes a full-fledged villain and creates a spanking monster to attack kids.
* Hama in ''WesternAnimation/AvatarTheLastAirbender'' is one of the creepiest examples. When first met by the protagonists, she appears as a sweet old lady with a sympathetic backstory and a mentor to Katara. [[spoiler:It eventually turns out she is a crazy sadistic woman who created the ability of Bloodbending and let her obsession with revenge toward the Fire Nation overcome her, causing her to kidnap and sequestrate Fire Nation civilians.]]
* Darcy from ''WesternAnimation/WinxClub'' does this in one episode. After seemingly saving Riven's life, she deliberately acts sweet and cutesy (she even says "My name's Darcy" while giving a big cutesy smile that make her two psychopathic sisters disgusted). Next episode, she's back to being a seductive and evil bitch who attempts to commit homicide against her rival for Riven (which shows how spiteful she is, given that she didn't even like Riven, and yet still wants to murder Musa just for liking him. Jesus).
* First time you see her, Josephine from ''WesternAnimation/SamuraiJack'' looks more like a StepfordSmiler FemmeFatale; it's when her smile wears off that you realize why she's so good [[PsychoForHire at her job.]]
* Mrs. Gerkin on ''WesternAnimation/JimmyTwoShoes''. Her first appearance hypes her up as a MisunderstoodLonerWithAHeartOfGold, only to reveal in the last moments that she is, indeed, everything Jimmy feared. Her next appearance has her causing a ZombieApocalypse.
%%* Marcia from ''WesternAnimation/BlinkyBill'' is basically this mixed with SociopathicHero.
%%* ''WesternAnimation/InvaderZim'': Tak from the episode "Tak the Hideous New Girl".
* In ''WesternAnimation/XMenEvolution''
** Pietro is introduced as one. At first, he pretends to be nothing more than a Rival, and even helps Evan in luring a trap against whoever's ripping him off. Then he reveals, in an awesome manner, that ''he'' is the one who's been messing with him, and leaves him framed for vandalism and theft.
** [[DatingCatwoman Kitty]] accuses Lance of this at the beginning of Season 3.
* ''WesternAnimation/SouthPark''
** Stan's older sister Shelly pulls this act in her introductory episode around her parents, only to [[BigBrotherBully beat him up]] in their absence.
** Butters' grandma has been revealed to be one as well, bullying her poor grandson when no one is looking. Apparently, [[ThereAreNoTherapists there is no foster care]] in South Park.
** Don't fuck with Wendy Testaburger.
** A lot of the other elementary girls can be this, to different extents. Don't get in the way of their love for shoes.
** Barbra Streisand in "Mecha-Streisand", at first.
* ''SupermanTheAnimatedSeries'':
** Superman's archnemesis LexLuthor, whose charm enables him to be a VillainWithGoodPublicity.
** "[[Recap/SupermanTheAnimatedSeriesS3E8SupermansPal Superman's Pal]]" has Tina. At the office, she looks like a pretty, [[TheDitz ditzy]] teenage girl. She's actually a hard-punching manipulator who even Metallo calls cold.
%%* Becky Benson from ''WesternAnimation/{{Recess}}''.
* [[OurGryphonsAreDifferent Gilda]] from ''WesternAnimation/MyLittlePonyFriendshipIsMagic.'' She's introduced as Rainbow Dash's BFF in "Griffon The Brush Off", but then she starts revealing [[JerkAss her true nature]] to the rest of the "dweebs". It's her bullying Fluttershy to tears that causes Pinkie Pie to finally draw the line with regards to her, and resort to "extreme measures... [[CrazyAwesome PINKIE PIE style!]]"
** The show also has a more extreme example in the form of [[spoiler:Chrysalis]] from ''Canterlot Wedding.'' [[spoiler:She disguises herself as Shining Armor's bride Cadence; just to harness his love for her as energy for her Changeling invasion of Canterlot; and imprisons the actual Cadence in the caves beneath Canterlot that most ponies had forgotten even exist. When Shining Armor's sister Twilight, having seen fake Cadence casting spells on Shining Armor, voices her own suspicions, fake Cadence plays innocent and makes it look like Twilight's only accusing her out of possessiveness of her brother. Fake Cadence then imprisons Twilight in the caves beneath Canterlot, away from the actual Cadence hoping neither will find the other.]]
*** What inverts this trope is [[spoiler: Fake!Cadence didn't really attempt to hide being a bitch at all ''except'' for when Twilight attempts to accuse her of being evil. The closest she did otherwise was when she said Applejack's treats for the wedding were okay and then proceeded to secretly throw them all out, but all other times she snapped at or insulted everypony she came across. The other members of the Mane 6 just didn't really pay that much attention to her behavior, or believed it was justified what with the pressure of the wedding coming up. The reason Twilight was suspicious in the first place was because the kind, sweet Cadence she knew from when she was still a filly behaved so radically different compared to now.]]
* ''WesternAnimation/TheSimpsons'':
** The Reverend Lovejoy's daughter Jessica. Everyone ''believes'' that she's a sweet, innocent minister's daughter, but (much to Bart's dismay) she's actually a manipulative little bitch. At the end of the episode her father is revealed to be well aware of her hellish behaviour, but overlooks it (to the extent of covering his ears and singing hymns at the loudest pitch possible) [[NeverMyFault and tries to pass the blame onto Bart instead]]. Given the addition of the Lovejoys' very fickle and conditional devotion to the bible and society, the Reverend and his gossipy wife may also count as this trope.
** At her worst, Lisa Simpson can become one of these. She plays the humanitarian a lot, [[ItsAllAboutMe but she also defines herself by a need to be better than everybody else]]. Several times, when a character shows up and is able to do something better than Lisa can, she sets out to publicly humiliate them. This is lampshaded in the episde ''Dial N for Nerder'', when she and Bart think that they accidently killed Martin. Bart feels guilty and wants to tell the truth and accept the consequences, Lisa bullies him into keeping quiet to avoid her going to jail. At the end of the episode Lisa says that there is a dark twisted person under her self-proclaimed innocent appearance.
* Qilby from ''WesternAnimation/{{Wakfu}}''. He's practically unrecognizable the moment he ditches the Sheep's Clothing.
* From ''WesternAnimation/TheLegendOfKorra''
** Hiroshi Sato seems nice at first. Cue episode 7 when he reveals himself as the EvilGenius of the Equalists who hates Benders with a passion. His real thoughts concerning Mako and Asami's romance are absolutely vile, and he calls Mako a "fire-bending street rat." He actually tries to kill Asami, his ''own daughter'', when she finds out. [[spoiler: He's no longer one in Season 4, where after years of being in prison, he comes to truly regret his actions and attempts to reconcile with Asami.]]
** Tarrlok also counts. He appears to be a politician who cares for the safety of the city, but that is just a cover for his real personality, a manipulative {{Jerkass}} that [[spoiler: plays most of the heroes, getting one of them to resign to position, almost got them killed, and even went into [[UpToEleven darker territory]] by creating laws that discriminate against non-benders, even being cruel on enforcing them. He is vicious enough to where he doesn't need a full moon to bloodbend.]]
** Kuvira from Season 4; while she is stoic both in public and private, she is still courteous and encouraging to others... until someone questions her, or refuses to do something she wants. Then she starts threatening her targets with death or "Re-Education" until they fall in line.
* Li'l Gideon from ''WesternAnimation/GravityFalls'' is an adorable child beloved by everyone. Just don't get on his bad side...
* ''WesternAnimation/BarbieMariposa'' has Henna, who is Mariposa's friend at first until she poisons the Queen and nearly kills all of the fairies in Flutterfield so she can take the throne.
* Literature/{{Goldilocks}} in the ''WesternAnimation/HappilyEverAfterFairyTalesForEveryChild'' is a mischievous girl who gets other kids in trouble, steals, and generally acts bad but acts innocent and sweet when needed (for example around her teacher). She even has a song bragging about how she can "get away with anything". By the end of the episode she's learned she can't.
