Bitches in Sheep's Clothing in Western Animation.
- American Dad!:
- Francine occasionally leans into this (or Beware the Nice Ones on lighter occasions), though, granted, she is called out on it or handed An Aesop more often than Lois.
- Watching a few Christmas episodes will show you 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.
- Barry is an odd example in that the friendly demeanor is genuine, but only because of the medication suppressing his evil urges.
- The Amazing World of Gumball: Season 1-era Mr. Small would typically start an episode as gentle and helpful, but once pushed slightly, would snap and either become passive-aggressive with the students or just explode and start yelling. He also had a cowardly streak and would flee whenever things started getting too crazy for his liking. Due to Characterization Marches On, this element of his character disappeared as the series progressed to instead focus on his hippie nature and conspiracy theories. Notably, his first major appearance in "The Painting" has him angrily yelling or even hurting the boys, something post-Season 2 Mr. Small would never do.
- Amphibia:
- Sasha Waybright fits more in the Alpha Bitch category in season 1, with it being pretty clear that she was always pretty bossy with Anne even when they were friends. However, she starts playing into this trope with her old friends in season 2 when she and Grime try regaining their trust with the full intention of betraying them (although it doesn't sit all that well with Sasha). When she finally does go through with the betrayal, Anne calls her out for being a horrible person, a remark that actually hits her pretty hard and makes her begin to rethink her choices. When she and Grime realize an even greater threat could potentially arise, Sasha attempts to warn Anne about the danger, but Anne justifiably no longer wants anything to do with her.
- Anne refuses to cooperate with Sasha until the real Bitch In Sheep's Clothing reveals himself: King Andrias. When Anne and the Plantars meet him, Andrias acts as a jovial Good King from a royal line of peacekeepers, but once he has the music box, he reveals that he's actually a descendant of Multiversal Conquerors and intends to continue the legacy. From here on, he sinks to such lows that Sasha and Grime seem like heroes in comparison, mockingly revealing Marcy's true motives of coming to Amphibia to her friends, destroying Frobo, attempting to crush Polly, holding Sprig hostage until he gets the music box back (then dropping him anyway), and topping it all off by stabbing Marcy when she helps Anne and the Plantars escape.
- Andrias eventually turns out to be a subversion. He's certainly vicious, but the ruthless tyrant is the real mask. The jovial goofball is who he actually wants to be, but years of his father and the Core's gaslighting and abuse has convinced him he has to be a monster to atone for his "failure" to protect the Calamity Box.
- Portia Demwiddy, from the Arthur episode, "Little Miss Meanie," definitely fits this trope. She's a contestant in a talent contest that Muffy and Lydia join, and acts all nice and sweet to the judges. But backstage, Portia is revealed to be a snob and a bully as she tells Muffy and Lydia that they should both quit the competition because they both have an unfair advantage (Muffy's rich and Lydia's in a wheelchair) Portia's true colors are revealed during the talent show when she is doing her act — a ballet dance — only for her spotlight to burn out and she's told that she'll have to do her dance without it. Portia gets angry at this, claiming that she needs the light, calls it unacceptable, and orders someone to be fired right before she throws a temper tantrum on stage in front of the whole audience.
- Hama in Avatar: The Last Airbender 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. 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.
- Batman: The Animated Series:
- Ferris Boyle from the 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 of the whole episode is knowing that Boyle will face justice for his crimes thanks to Batman.
- Pamela Isley is this in the episode "Pretty Poison." Initially presenting herself as Harvey Dent's loving sweetheart he's eager to wed, despite only knowing her for a little over a week. Shortly after Harvey's rendered comatose a rightly suspicious Batman goes to confront Isley at her greenhouse and is seized by a giant mutant flytrap. Pamela then reveals her costumed, Femme Fatale eco-terrorist alter ego while demonstrating her grief stricken girlfriend facade to him before erupting into wicked laughter, confirming whatever affection she showed Dent was never sincere.
- Paxton Powers from Batman Beyond, as shown in the Season 1 finale "Ascension". Not that he was much of a nice guy to begin with, but he initially puts up the facade of being concerned for his father's health and safety. He later reveals that he purposely set up the protest by the Verdeza activists in order to expose his father as Blight. He then hired Batman to search for Blight pretending to plan to help him, when he was actually intent on killing Blight and taking control of Wayne-Powers for himself.
- Castlevania:
- Carmilla The Starscream is this throughout Season 2 feigning loyalty to Dracula, she at first appears sincere to Hector but manipulates him into betraying Dracula and sadistically tortures him as soon as she has Hector within her power.
- Lenore from Season 3 is in many ways even worse than Carmilla who at least was upfront with her cruelty. Lenore lulls Hector into a false sense of comfort and even goes as far as to have sex with him just so she can ensnare him to her will. Subverted in Season 4, having developed their relationship offscreen Lenore's feelings for Hector have become genuine as when Isaac invades the castle Lenore frantically rushes to Hector's location wanting to escape with him to safety, unaware Hector has already planned his exit and aided in the destruction of Carmilla's empire. In the ending Lenore does apologize for what she did to Hector, before walking into the sunlight.
- Sumi and Taka from the same season appear innocent and heroic when they meet Alucard and succeed in befriending and seducing him. As soon as Alucard is at their mercy they try to kill him before getting their throats slit by his summoned sword and then put on spikes outside his castle.
- Also there’s also the Judge of Lindenfeld who seems a Reasonable Authority Figure who's just a bit pompous. Until the finale reveals he’s killed dozens of villagers especially children in a spike pit and kept their shoes as a sick fetish.
- The Alchemist woman Saint Germain meets in the Infinite Corridor seems like a textbox Mysterious Waif being quite polite and serene turns out she's Death in disguise manipulating Germain into triggering the apocalypse.
- Saint Germain himself becomes one while duping Alucard, Greta, and the rest of the innocent people he's traveling with, his affable persona belied by his real intentions of killing everyone for the sake of seeing the woman he loves again. Although Germain does Heel–Face Turn at the last minute to save Trevor.
- In Codename: Kids Next Door, 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 spaceship 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 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.
- The Fairly OddParents!:
- Vicky 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 is the very reason why Timmy is miserable enough to have fairy godparents in the first place.
- Subverted when 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.
- Super Bike seems like a friendly companion to Timmy, but he's really an emotionally manipulative yandere who tries to isolate Timmy from everyone else.
- Family Guy:
- Lois 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 Meg (she merely mumbles it) on her wedding day, no less. Lampshaded in one episode where she is described as "more of a bitch than she lets on."
- The Sickeningly Sweet New Brian bonds with the family so well that he seems to be a perfect replacement for Brian until Stewie finds out something incredibly dark about him: the dog humped Stewie's teddy bear Rupert. 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. 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.
- Futurama:
- Leela dates the Mayor's Aide in "The Why of Fry", 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.
- Mom maintains the image of a grandmotherly industrialist, but she is secretly a bitter old hag and a Corrupt Corporate Executive.
- Gasp!: In "The Cat in the Flap", a bedraggled stray cat plays on the sympathies of the kids in a crafty attempt to get the pets evicted and take their place.
- Gravity Falls:
- "Li'l Gideon" Gleeful is an adorable child beloved by everyone in town... but he thinks they're a bunch of credulous idiots, and he knows about the journals and is secretly plotting to get his hands on them.
- Bill Cipher may seem chummy and affable, but is really a murderous Psychopathic Manchild of a Reality Warper.
- Goldilocks in the Happily Ever After: Fairy Tales for Every Child 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.
- Horrid Henry has Perfect Peter, the titular character's Annoying Younger Sibling. He acts friendly towards his parents, cementing him as the favorite, but he takes utter pleasure in getting Henry in trouble.
- Invader Zim: Tak from the episode "Tak the Hideous New Girl". She presents herself as the mysterious, cool new girl in town, but she's actually worse than Zim.
- Invincible (2021):
- Omni-Man presents himself as the heroic savior of the world despite actually being something more malevolent and ruthless than his Earthling colleagues realize. After the funeral of the Guardians of the Globe where he calls them his friends, he acts callous and claims they were just his co-workers.
- Ironically inverted by D.A. Sinclair. As a civvie, he's an obnoxious, condescending prick who makes sure everyone at university knows how much of a genius he is and how lowly he thinks of any viewpoint other than his own. When he's about to operate on one of his victims, he's very Faux Affably Evil by comparison.
- Mrs. Gherkin on Jimmy Two-Shoes. Her first appearance (a "Rear Window" Homage) hypes her up as a Misunderstood Loner with a Heart of Gold, only to reveal in the last moments that she is, indeed, everything Jimmy feared. Her next appearance has her causing a Zombie Apocalypse (although that ultimately turned out to be All Just a Dream).
- The titular character of Kaeloo can be this at times. Examples include "Let's Play Courtroom Drama", where she pretended to be leaving Smileyland to get Mr. Cat to confess to a crime, and Episode 58 where she sets up a horrible game show for Mr. Cat to compete on where he suffers even if he wins.
- King of the Hill:
- Big Willie Lane is known as a hero who won the Super Bowl for the Dallas Cowboys football team and is adored for it among fans. He may seem like a cool guy who parties a lot, but he's really a selfish, annoying Jerkass who bullies people who don't treat him with respect. Even worse, he gains respect from the police force, who also view him as a hero, and doesn't receive punishment from them at all when he commits felonies. Hank Hill has a Heel Realization when he finds out that Willie has been violating the law and terrorizing the neighborhood, prompting him to stop Willie from ruining the lives of others around his once peaceful street.
- Luanne appeared to be innocent and sweet most of the time, but she did have some vindictive motives once in a while, like in an episode when Peggy was in a contest and Luanne got pissed off that Peggy didn't want her to do her hair and gets revenge on Peggy.
- From The Legend of Korra:
- Hiroshi Sato seems nice at first. Cue episode 7 when he reveals himself as the Evil Genius 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. 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 plays most of the heroes, getting one of them to resign to position, almost got them killed, and even went into 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.
- Unalaq from Season 2; he tries to act like a benevolent hero who wants to guide the Avatar on a righteous spiritual path and bring both the Northern and Southern water tribes together as one, but then it turns out that he's been making not so heroic decisions...
- 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.
- The Loud House: Lynn Loud Jr. seems like an innocent girl who could do little wrong. Once you get to know her, you'll realize that she'll very often use roughhousing as a means of resolution. Though she tends to zigzag between this and Jerk with a Heart of Gold.
- Lila Rossi in Miraculous Ladybug is a Consummate Liar that acts out to get her way. She acts pleasant to her "friends" (read: the people who buy her lies) while being downright vicious to those who get on her bad side (by calling her out), and is willing to go as far as willingly siding with Hawk Moth in order to torment the latter.
- My Little Pony: Friendship Is Magic:
- Flim and Flam are a pair of traveling con men, and as such, appear friendly on the outside to trick ponies out of their money.
- Suri Polomare pretends to be friendly with Rarity before stealing her designs and taking advantage of her generosity.
- Starlight Glimmer is a major antagonist who pulls off the 'sheep's clothing' part of this trope pretty well, at first as the friendly leader of a small community of ponies who willingly gave up their cutie marks to achieve equality and harmony, but she also will force ponies to give up their cutie marks if they don't do so willingly and is more of a cult leader than anything. It is obvious that she doesn't practice what she preaches, as it's revealed that she never gave up her own cutie mark and mostly enjoyed having power.
- Cozy Glow pretends to be a nice and sweet filly but is actually an evil sociopath who is seeking to conquer Equestria.
- Sonata Dusk, from My Little Pony: Equestria Girls – Rainbow Rocks, is this- she seems like the nicest of the Dazzlings, but is in fact just as evil as the other two.
- Sour Sweet from My Little Pony: Equestria Girls – Friendship Games, is also this, though in her case, the clothes don't fit very well- her attempts to seem nice feel saccharine and transparently false, and almost always immediately follows up the false sweetness with sour, openly malicious, non-subtle sarcasm. While near the end, she shows that she is perfectly capable of being genuinely nice, but even that is followed by abrasive bitterness.
- The Owl House:
- Amity's siblings Edric and Emira in their debut episode. In their initial episode, they appear very charming and friendly but are known troublemakers and have a tendency to pick on Amity. This is heavily downplayed in future episodes after they realise their pranks endangered both their sister and Luz and work to make up for it. Subsequent appearances later on show that while they're still pranksters, they truly do care about Amity and are on good terms with Luz too, effectively inverting this trope.
- Mattholomule in his debut episode. He offers a seemingly sincere story about feeling alone as the new kid to deflect blame for lying about his human "artifacts", then calls the guards on Luz to get her thrown into detention.
- Severely downplayed with Willow, and in a different flavor than Amity: while she's genuinely as nice as she acts and looks, she hides quite a lot of repressed vindictiveness, again, towards Amity.
- A lighter example than most in "Escape of the Palisman". The snot-nosed kid at the playground really was trying to depose King and taunts him about giving up his throne to save Eda.
- Tibbles. He seems kindly and polite at first, but quickly reveals this to be a ruse and he's actually a horrible Fluffy the Terrible Jerkass.
- In "Through the Looking Glass Ruins"; Bria, Gavin, and Angmar act polite and supportive to Gus, but turn out to be jerks who want to use the power of the Galdorstones to take charge at Glandus. Bria, in particular, stands out for putting on a facade of being a sweet, cheery Nice Girl who wants to change The Social Darwinist attitude at Glandus High before dropping the act and revealing her true Alpha Bitch self once they get the stones.
- Jacob Hopkins in "Yesterday's Lie". When Vee talks to him for the first time while he is working at the museum, he comes across as a very friendly, upbeat, and polite person who is just doing his job. However, it's revealed that he is an out-of-touch egotistical Conspiracy Theorist who doesn't care if innocent creatures get hurt as long as he gets famous for exposing magical creatures to the human world.
- Philip Wittebane is initially hostile to Luz and Lilith when they encounter him in "Elsewhere And Elsewhen", but quickly warms up to them, and is very polite and kind to Luz when she shows him what she's been working on. This all turns out to be a ruse, however, as the only reason Philip brought them along on his journey was to use them as bait to distract the Stonesleeper guarding the Collector's mirror, to the point where he writes their deaths into his journal before they've even happened. Gets even worse when it's revealed that Philip would later become Emperor Belos, who takes great glee in rubbing Luz's face in the fact that she helped him in his quest to wipe out witch-kind.
- Suzy Johnson on Phineas and Ferb, 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 Buford, but the audience has never seen her do it.
- Becky Benson from the Recess episode “A Science Fair to Remember” pretends to befriend Gretchen so that she can steal her science project. She does mend her ways in the end though.
- Jerry Smith in Rick and Morty is an insecure Extreme Doormat with no confidence but frequently reveals himself to be petty, arrogant, and self-serving while he can barely function in normal society to the point his unemployment becomes a Running Gag. In his "The Reason You Suck" Speech to him, Rick states that he's a predator that acts like prey.
- Angelica Pickles in Rugrats (1991). She manages to pull it off almost flawlessly by being absolutely adorable
◊ and knowing how and when to put on a sufficient "good girl" facade to fool the adults (although she still has somewhat of a "Spoiled Brat" reputation in-universe). All in all, she knows how and when to behave well (despite it arguably not being her nature), and she also knows when she can get away with being nothing short of nefarious. - First time you see her, Josephine from Samurai Jack looks more like a Stepford Smiler Femme Fatale; it's when her smile wears off that you realize why she's so good at her job.
- The Simpsons:
- 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 behavior but overlooks it (to the extent of covering his ears and singing hymns at the loudest pitch possible) 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, 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 episode "Dial N for Nerder" when she and Bart think that they accidentally killed Martin. Bart feels guilty and wants to tell the truth and accept the consequences, but Lisa pressures him into keeping quiet to avoid her going to jail. At the end of the episode, Lisa, to her own horror, says that there is a dark twisted person under her self-proclaimed innocent appearance.
- Les Sisters: In one episode, the Alpha Bitch Rachel comes to stay at Wendy and Marine's house for the weekend. She is incredibly kind to the parents despite Wendy trying to tell them she's anything but nice, and she compliments Marine and gives her a free perfume and an Affectionate Nickname, tricking Marine into believing that she is a nice person. When the parents go out for the night, Rachel shows her true colors by locking Marine and Wendy out of their own house and throwing a Wild Teen Party inside the house.
- South Park:
- Eric Cartman can be this at times, acting nice in front of the adults while hiding the fact he has a notorious scheme on his hands. One notable example is in "Le Petit Tourette" where he pretends to be an innocent little boy with Tourette's Syndrome so he can have the excuse of doing whatever he wants.
- Stan's older sister Shelly pulls this act in her introductory episode around her parents, only to 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, 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.
- SpongeBob SquarePants: While Puffy Fluffy and the other exotic fish of its kind seem to be innocent and harmless, they can act viciously towards other pets, especially snails.
- In Steven Universe, Navy is this in the episode Room for Ruby, pretending at first to want to join the Crystal Gems, and then ultimately ditching them once they let her see her old ship. When Steven asks why she didn't just steal the ship in the first place, she tells him she wanted to see the look on their faces when she got the ship back and delights in the fact that she tricked them, all with the same soft voice she always uses.
- Superman: The Animated Series:
- Superman's archnemesis Lex Luthor, whose charm enables him to be a Villain with Good Publicity.
- "Superman's Pal" has a double example of nastiness being hidden under a good-natured exterior:
- Tina, the Planet's new intern and Jimmy's crush. At the office, she looks like a pretty, ditzy teenage girl. She's actually a hard-punching manipulator who even Metallo calls cold.
- Angela Chen, the Planet's gossip columnist. Up until this point, she was simply the other journalist in town, the one not quite as competent as Lois or Clark. However, here she suckers Jimmy into an interview he didn't want and uses Manipulative Editing to change his words into the exact opposite of what he meant. Aside from being a very unethical thing for a reporter to do, it also nearly gets Jimmy killed. Twice. Worse, when he tries to tell her that she has put his life in danger, she laughs him off.
- Teenage Mutant Ninja Turtles (2003): In his first appearance, the Ultimate Ninja was a Jerkass who cheated in a duel with Leo, and tried to kill him after being officially defeated. When he next appears during the Battle Nexus arc, he acts friendly to the Turtles and claims to be regretful of his actions toward them, but it's soon made clear he hasn't changed one bit; he's conspiring to murder his own father to steal his War Staff and goes so far as to shoot Leo with a poison dart out of pettiness and spite.
- Total Drama:
- From the first-gen cast, Courtney. At her introduction, she seemed civil and polite. However, as the series progressed, she reveals herself to be almost as much of an Alpha Bitch as Heather. Courtney's overly competitive and bossy personality has alienated virtually everyone she meets.
- World Tour's newcomer and Big Bad Alejandro presents himself as a suave, charismatic, and gentlemanly casanova who makes the ladies swoon with his looks and charms. However, he soon reveals to the audience that he is in fact a cruel, selfish, and heartless bastard who sees the women he charms as puppets for him to exploit remorselessly — something pretty much all the contestants only find out once they've been eliminated by him.
- From the third-gen cast, Scarlett. At first glance, she appears to be an awkward and rather shy genius. However, she quickly allies herself with the Harmless Card-Carrying Villain Max, and her seemingly nonthreatening facade hides her true murderous and psychotic personality.
- From the fourth-gen cast, Julia. She initially presents herself as a positive Granola Girl influencer who wants to share her positive energy with everyone. However, she is soon exposed to the whole world as a Bad Influencer who has no problem insulting and intimidating those around her to achieve her goals. This initially leads to her losing many followers on social media, but they are soon replaced by thousands of new followers who are implied to enjoy her true self, leading her to decide that she enjoys not having to pretend to be nice, and to fully embrace her real spiteful personality.
- The Ice Dancers from Total Drama Presents: The Ridonculous Race. They act like Canada's sweethearts with smiles plastered on their faces, but they have a more sinister side underneath, especially the violently ill-tempered Josee. Jacques, on the other hand, seems to be more "Sheep" than "Bitch" at times, but the series does remind the viewers why they get along at all. Ennui calls Josee out on this in "Down and Outback" when she pretends to act friendly in an attempt to borrow his makeup.Josee: (to Ennui) Oh! Hey there... buddy. Do you mind if I borrow some of your makeup? (smiles and laughs nervously)
Ennui: Don't pretend to be friendly. It's gross. - The Venture Bros.: 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.
- Qilby from Wakfu. He's practically unrecognizable the moment he ditches the Sheep's Clothing.
- Darcy from Winx Club 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 makes 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).
- In X-Men: Evolution:
- 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.
- Kitty accuses Lance of this at the beginning of Season 3.
- Zorro: The Chronicles
- Dona Isabella Verdugo appears to be quite a noblewoman, and behaves that way in public...but, in reality, she's a manipulative Social Climber who's determined to make her husband the alcalde (municipal magistrate) of Los Angeles and is willing to do anything to get it done. Only Don Malapensa and Zorro know her true nature — the former because he's being blackmailed to do her dirty work, the latter because he accidentally stumbles across the truth behind one of her schemes.
- Rosa, the Identical Stranger Dona Verdugo hires to impersonate Ines in "The Impostor," is this as well. At first, she appears to be a genuinely sweet girl who only participates in the plot because she's been told it's a harmless prank. Then she figures out it's not harmless at all...and she's more than willing to go along with it, so long as she's well paid.
