** One-time character, Nicholas Locarno, while nice and charming on the outside, was actually a really nasty person beneath the surface, according to WordOfGod.

** Admrial Norah Satie is a particularly nasty case of this as seen in the episode "The Drumhead". At first Satie seems like a CoolOldLady who has the best interests of the Piccard and Federation while they are investigating a possible sabotage attempt (later revealed to be a accident) from a possible Romulan spy among their ranks. Satie effortlessly charms Piccard and inspires passionate determination from even Worf, however it turns out Satie is a ruthless KnightTemplar who starts a fearmongering WitchHunt, cruelly interrogates and ruins the career of a young medical technician who has Romulan grandfather and lied about on his Star Fleet application. When Piccard prevents her interrogations, Satie puts him on trial, accusing Piccard and the Enterprise crew of being Romulan colabrators. Thankfully Piccard shoots her down with [[ShutUpHannibal excellent speech]] recited from own father's memoirs. This trope is even lampshaded at the end.

* 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.

** ''Series/KamenRiderBlade'': [[DarkChick Miyuki Yoshinaga]]/[[PlantPerson Orchid Undead]] was introduced as a NiceGirl who ended up being Kotaro's girlfriend, but in reality was trying to lure him into a trap to kill him and make Kenzaki surrender his Blay Buckle. She later keeps up the nice act with Mutsuki, but for his Remote Tapir card, in hopes of unsealing her fellow brethren just to reignite the Battle Fight, only to backfire as the Rider fights back against her.

** Karen in Season 4, in her first apperance seems like just outgoing and charming valley girl, but her AlphaBitch nature is still palpable as she looks down on El and criticises her hero presentation about Hopper. Out of class she puts up no pretence and is wickedly cruel to Eleven and only puts on the sheep clothes again at the roller rink in order to publicly humilate her. This only makes the scene where El snaps and breaks her nose all the more satisfying.

** One that is more easily missed, is Laura Cunningham, Chrissy's mother. When we briefly see her in the flesh [[spoiler:at her daughter's funeral]] she seems like geuinely grieving and loving mother but as seen but Chrissy's Vecna-induced nightmares she is really a horribly absusive woman who put a massive amount of WeightWoe on her daughter and caused poor Chrissy to develop an eating disorder. Unike the rest examples listed here, she's a KarmaHoudini.

* And let's hear it for Grace Whitney of ''Series/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.

** 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 "[[Recap/AngelS01E05RmWAVu Rm w/a Vu]]".

* ''Franchise/KamenRider''

** Chuck [=McGill=], who starts out seeming to be Jimmy's LawfulGood, very straight laced, but supportive older brother. Except then it turns out that he pathologically despises the fact that Jimmy's a lawyer like he is, to the point he's been purposefully impeding Jimmy's career at every turn, while making his law partner Hamlin take the blame for it.
