Bitches in Sheep's Clothing in Fan Works.
Crossovers
- Equestria Girls: A Fairly Odd Friendship:
- As she usually does, Vicky pulls this act, pretending to be Timmy's loving babysitter in front of Miss Cheerilee.
- Invoked by the Dazzlings, who use Sunset's past two-faced behavior as part of their bid to convince Timmy that they're kind and heroic beings who want what's good for him. In reality, they're as heartless as ever and just want Timmy for his magical prowess.
- The Last of Us Series (Once Upon a Time, The Last of Us): When Regina first meets Robin, he at first seems like a kind and reasonable guy, but quickly reveals himself to be a cannibal and rapist who grows obsessed with Regina.
- Tales of Taskforce Sol has Anniten. She looks like a sweet love interest for the protagonist SunTzu, who just wants him away from war. She is in fact a ruthless, crazy, cowardly enemy spy.
- Danny unfortunately finds himself going out with a few of them in The Many Dates of Danny Fenton, such as Cree Lincoln and Vicky from The Fairly OddParents!, who are like their canon selves.
- In A Triangle in the Stars, Bill Cipher puts on an air, sometimes thin, of friendliness and innocence, moreso for Steven, only letting his true colors slip occasionally, and his hidden plan is to backstab everyone he can string along when his powers get restored.
- Teen Titans Tokyo:
- Blackfire sits on the border of this and Villain with Good Publicity, setting herself up as Tokyo's new superpowered protector whilst secretly planning to recruit gullible super-teens as weapons against the real Teen Titans.
- Kasumi Tendo pretends to be her classic homemaker self, but is really a Psycho Lesbian supervillain and thrall to a half-demon sorceress.
- What It Takes: Felicity Smoak, who everyone initially believes to be a quirky and awkward woman who nonetheless means well, only to turn out to be a selfish Control Freak with Never My Fault tendencies. One of the reasons why nobody holds it against Oliver for being gullible enough to believe Felicity and thinking everything was fine in Starling for so long is because none of them thought Felicity was capable of that level of duplicity and selfishness either.
- Lacie in Falling in Deeper is said to be one, with an obsession in being just perfect in everything. It's also implied that 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 who has run away from Arkham and just escaped the Scarecrow and she teases her about all that happened long enough that the Scarecrow finds her and takes her with him.
- Operation F.A.T.T.Y
introduces Gallagher Elementary's newest lunch lady, Ms. Greta and while Sector V is naturally suspicious, they soon come to trust her due to her amazing food and the fact she's willing to defend the students from other adults. It turns out that she's actually Grandma Stuffum's daughter and is simply going about her mother's plans in the opposite direction-via letting the kids fatten themselves up with her food so that they're too fat and lazy to do anything.
- Where Talent Goes to Die has Reiko Mitamura, the Ultimate Proofreader, as a downplayed example. In addition to her talent, she has excellent grades and manners, and most of the students respect her as their leader. That said, it's also implied that she secretly harbors a selfish desire for her parents' approval and her peers' respect, and in a more lighthearted sense, is also a Yaoi Fangirl despite her disapproval of pornography and homosexuality. It's fully played straight when, after learning that Monokuma will release evidence of her cheating on a test unless someone commits murder, she poisons Mizuhara and tries to frame Sugiura in order to graduate, thus ending up as something of a Broken Pedestal to Iwasawa and the others.
- Anzu Sugiura plays with this. After it's revealed that she is actually the Ultimate Poisoner, she drops the polite façade she'd adopted, and ends up acting more brusquely and rudely to most of her classmates. That said, she turns out to not be guilty of the second murder, or the third. In the end, she does commit murder, but only kills Iwasawa (a willing victim) to prevent Miura's family from being killed, and reveals that she actually did not commit the murder that earned her the Ultimate Poisoner title.
- Sousuke Kagami is a male example and definitely worse than the two girls above him. He pretends to be a pleasant if a bit distant guy with amnesia, then it's revealed that he’s the Mastermind of the Killing Game. And his reason for doing this? Because the school titled him the Ultimate Copycat.
- Disney Villain Songs (Lydia the Bard): In Belle's Villain Song, she's revealed to be The Resenter, secretly scorning the villagers for how they treated her, as well as hating the Beast and his servants for making her trade herself for her father's safety. She still played the part of the Nice Girl seen in the original film, betraying the Beast's trust once his guard is completely lowered and revealing herself as a Soft-Spoken Sadist, mockingly asking throughout her song whether he actually believed he could lock up the smartest woman in her village and not face reprisal.
- Five Nights At Freddy's: Lost Souls: Golden Freddy acts friendly towards his fellow animatronics and Bridget, but for some reason bears a hefty grudge towards Cody and not so subtly threatens him into leaving the amusement park for good, implying something will happen to Bridget if he doesn't.
- From the discontinued mod VS Sky: Sky at first seems to be a cheerful if obsessive girl who deeply loves and admires Boyfriend. Then it becomes clear that she can't take "no" for an answer.
Grandmaster of Demonic Cultivation: Mo Dao Zu Shi/The Untamed
- In A Game for the Fool, the unnamed pedophile that attempts corner the five-year old Wei Wuxian is noted to be well-groomed with fine robes and have a friendly face and voice that seems oh so concerned for this potentially lost child. Wei Wuxian's Stranger Danger senses tingled, and he immediately sees through the man as a pedophile.
- In Impenetrable Walls, Jin Guangyao is potentially this. Wei Wuxian refuses to trust him on the grounds he's related to Jin Guangshan, and Lan Wangji definitely doesn't like him either, but there's nothing definite.
- Lan Sizhui Sees Dead People plays it for laughs. Lan Sizhui is adored by the Lan Sect, especially by his grand-uncle Lan Qiren, for being the embodiment of Lan ideals. Lan Sizhui however is just as mischievous as his adoptive "mother", frequently pulling pranks with nobody suspecting that it's him.
- The Choices That Make Us: The only Azakaban to treat Sirius well is a man named Gibbon, and it turns out this good treatment is because he is a Death Eater sympathizer who thinks Sirius really did betray the Order of the Phoenix.
- Jenny from Ebony Dark'ness Dementia Raven Way vs. Canon seems like an average teenager who happens to enjoy Trolling the Internet. She then reveals herself to be a pretty nasty piece of work.
- The Very Secret Diary: The fic explores Ginny Weasley's year at Hogwarts, and how she came under Tom Riddle's thrall. Tom exploited Ginny's naïve and trusting nature, pretending to be her friend while stringing her along.
- Emma Hunter of Lincoln Learns The Hard Way comes off as sweet and friendly with a soft spot for babies when Lincoln meets her in the park. But in reality she fully intends on having sex with the 11-year-old, willingly or not. And Lincoln's not the first kid she's tried it with.
- An Alternate Keitaro Urashima has Granny Hina, who tries to pass herself off as a Cool Old Lady who's only got everyone's best interests at heart when she's really a Manipulative Bitch. 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.
- Henri LeRoi, the titular Jerk in Sheep's Clothing, first introduces himself to Marinette as the kind, eternally loyal companion she has been wishing for since Lila started trying to pit the class against her. He takes her at her word about the liar and keeps her company. But in truth, he’s actually secretly working with Lila to isolate Marinette completely, bullying all her friends behind her back and then making it look like the other way around, and giving her reasons to doubt them and their loyalty, all so Marinette will sever ties with her friends and devote herself entirely to Henri.
- The Karma of Lies:
- Lila Rossi manipulates the majority of her classmates into seeing her as an even better version of their friend Marinette, with better connections that she's more than happy to use to help them achieve their greatest dreams. In reality, she's a complete Con Artist who not only scams them into donating to her fake charities but actively sabotages their prospects by stealing and selling off their work.
- Adrien also counts; while he honestly considers himself to be a good person, he's actually more than happy to let Lila continue scamming his friends just so he doesn't have to be the one to break the bad news of her true nature to them. He also goofs around as Chat Noir, refusing to take his responsibilities as one of Paris' protectors seriously — after all, his partner has a magical Reset Button, so who cares what he does so long as she wins in the end? This attitude comes back to bite him in the end. Hard.
- Leave for Mendeleiev: Adrien acts like a model student, but his preferred way of dealing with conflicts is trying to shut down and guilt-trip anybody who doesn't agree with him, refusing to consider their point of view. He shows a deeply entitled streak towards Ladybug, trying to learn her Secret Identity and force his affections upon her. He also exploits the power he holds over his kwami Plagg and proves to be a Toxic Friend Influence on Nino by encouraging him to take advantage of their akumatized classmate. Highlighted quite nicely in his treatment of Marinette and Aurore. Since they aren't classmates, he ignores their existence until he starts suspecting that Marinette might be Ladybug. He subsequently strings Aurore along, ignoring her crush on him while trying to get closer to Marinette. Once he has reason to believe she isn't Ladybug after all, he promptly snubs both girls the next time he sees them, walking past without acknowledging their friendly greetings.
- Once Bitten, Twice Shy applies this to both Lila and Adrien. Lila has convinced most of the class that Marinette has been bullying her with her efforts to expose her as a Manipulative Bitch. Adrien, for his part, is fully aware of the truth, but not only is he staying silent on the matter, he's secretly pleased that Lila has destroyed Marinette's reputation. Why? Because Marinette slapped him once when he claimed that the Consummate Liar "wasn't hurting anyone" with her deception. Far as he's concerned, that means Marinette deserves to suffer, and he enjoys her misery while pretending that he's not doing anything to contribute to it.
- Watch Me Burn:
- After learning Ladybug's Secret Identity, Adrien starts romancing her as Marinette... without letting her know that he's also Chat Noir, while cranking up his misbehavior in his 'heroic' persona, intentionally cultivating a Likes Clark Kent, Hates Superman scenario for his own amusement. He also exploits Marinette's crush on him to tease and torment her further by suggesting they should make their relationship more intimate than she's comfortable with, and intends to string her along for as long as possible before revealing the Awful Truth... and making clear that she can't escape him.
- However, Adrien dramatically overestimates what others will blind themselves to. After one of his stunts as Chat Noir goes viral, exposing his true nature to all of Paris, he drops the pretense of being a hero entirely and only shows up to fights in order to harass Ladybug and openly get in her way. Marinette is also growing increasingly uncomfortable with Adrien's advances before his disregard of akuma blows up in his face via Rat King getting the drop on him, revealing his secret identity.
- In Shigeko Kageyama AKA Mob, Asagiri Minori is convinced Mob is this. Mob, of course, is not.
My Little Pony: Friendship Is Magic
- Asylum (Daemon of Decay):
- Nurse Ratchet (based on the character of the same name from One Flew Over the Cuckoo's Nest) acts like a kind and caring head nurse, but it only takes a few minutes of listening to her condescending tone and controlling personality to realize the kind of pony she really is. Even the orderlies are terrified of the mere thought of making her angry.
- Dr. Rose, Twilight's primary doctor and the head of the new experimental treatment he is having her undergo. In person, he acts like an understanding stallion who genuinely wants to help ponies and is even one of the few doctors that has faith in Applejack, who faces prejudice in the medical field do to being an Earth Pony. But in secret, he's a Manipulative Bastard who is only nice to Applejack or his patients to keep them under his control and plans on risking Twilight's and many other unicorn's lives just so he can get his name in the medical textbook. Or at least so it seems...
- It should be noted that we only really see them through Twilight's eyes, who is a patient at the titular and it is not made clear if we can really trust what she believes she sees.
- A Diplomatic Visit: Cozy Glow seems sweet and innocent on the outside, but once Twilight figures out her secret in chapter 10 of Diplomacy Through Schooling, she admits that she's really out for power.
- The Flash Sentry Chronicles: Lightning Dust is this just like in canon, though it is much more blatant. She and Rainbow start off on good terms, but Lightning makes it clear she has no interest in making friends and thinks they would only slow her down. When Rainbow is made lead pony instead of her, and she is just Rainbow's wing pony, she drops the "in sheep's clothing part" entirely and becomes openly hostile to Rainbow, disobeying every order she gives to try to prove she is better than her.
- A Future of Friendship, a History of Hate: When Regal Rule is introduced in Episode 4, he at first appears to be Rarity's long-awaited Prince Charming, but it soon becomes apparent to the reader that he's trying to drive a wedge between her and her friends. And then he turns out to actually be Megalos Tyrant, one of Ruinate's heralds (specifically, the Element of Arrogance).
- Inner Glory has Spectral Slash. She's the sympathetic kind of Bitch, and she never does anything too terrible, but it's made abundantly clear she's this when she not only attacks Rainbow for disturbing her but sells Twilight and her friends out to her true allies the first chance she gets.
- Loved and Lost: In the first four chapters, Prince Jewelius is presented as a humble nice cousin of Princess Cadance who becomes close with Twilight Sparkle and supports her as she ends up becoming alienated from her friends, brother, and mentor for "disrespecting" the false Cadance. Right after he helps Twilight in exposing and defeating Queen Chrysalis, however, he turns arrogant and hostile towards all the other heroes as he exposes their mistakes to the public and blames them for the Changeling invasion ever happening. He then has the princesses dismantled and makes himself Equestria's king, manipulates Twilight into becoming his faithful pawn, and turns all the other heroes into hated pariahs. He actually collaborated with Queen Chrysalis to take control of Equestria from the princesses he has secretly hated for years, but he double-crossed Chrysalis once he decided Twilight to be more valuable to him as a broodmare. He's sociopathic to the degree that Cadance's love spell cannot induce love in him, and the Changelings cannot find from his heart any love to feed on.
- My Choices: Twisted Tales Through Time: Lady Blueblood, who makes her descendant from the original timeline look like a saint in comparison. When Blue Star is first appointed to Celestia's court, Blueblood attempts to take advantage of their similar-sounding names by claiming they're related. Once Blue Star makes clear that the two of them have very different priorities, Blueblood actively attempts to use the Royal Court to put an end to the changes Blue Star is trying to bring about to Equestria.
- Sirens of CHS has Sonata Dusk. She seems cheerful, ditzy, and innocent. She also cheats at video games, sets anthills on fire with an evil grin, and acts disappointed when she's told she can't beat up human!Twilight.
- A Growing Affection: Out of the three Konoha elders, Homura initially appears to be the most kind and reasonable. Then it's revealed that he's been working with Gouki for almost the entire story.
- In More Than Meets the Eye, Ash returns to Cerulean City to find that Misty is engaged, but Ash soon learns that her fiancé, Chris, intends to take the gym from her after the marriage and then divorce her. This stems in part from Chris not wanting to be 'overshadowed', contrasting Ash's ability to accept when others might be better in certain areas than he is.
- In the sidestories of Pokémon Reset Bloodlines, it's revealed that Cipher admin Capriccio managed to put up a respectable facade to almost get married to Jeanette Fisher's mother, Kaoruko. It didn't help that he was favored by Kaoruko's father, who disapproved of his daughter's romance with her eventual husband Kazuto, until he exposed Capriccio as the criminal he was.
- In the fic My Name Is Cinder, Cinder's mother, Brigit Stark, presents herself as a kind woman who cares about her children and her husband's depression. She even mourns him when he eventually hangs himself. However, the truth is that she's a sociopathic Gold Digger who couldn't care less about her family and was the reason her husband killed himself in the first place, by admitting the truth about her. When Cinder tries to expose her, Brigit manipulates her brother and sister into hating Cinder so she can get away with abusing her.
- Ruby and Nora: In Weiss and Pyrrha, Nurse Abigail Lemon presents herself as a kind and approachable woman when she comes in to check on Weiss after being stabbed by Admah Keter. However, she quickly shows her true colors when she tries to make Weiss OD on morphine. When Pyrrha catches her in the act, Abby reopens the stitches and uses her EMP Semblance to kill everyone on life-support in the hospital. Later in the story, the staff reveals that patients under her care tend to die often, implying that she's been playing this trope for a long time.
- This is making a move: Jill Roberts was already one in canon, but the fanfic expands on her manipulation of her accomplice Charlie through promising affection, sex (they have sex after killing Marnie and Jenny in the film's opening), and the prospect of revenge against his Abusive Parents to string him along until she had no more use for him.
- Total Drama What If Series This is the reason why Sugar hates Ella and Dawn. She believes that their kindness is just a facade to hide the fact that they're jerks. Subverted, as the two aren't faking anything.
- Unbreakable Red Silken Thread: Zigzagged; in public Scarlett is a quiet girl, but at her job, she let her Jerkass side show.
