Both Marcia and Jan — and once, even little Cindy — have had conceited, holier-than-thou moments, only to realize that they alienate others, most notably their siblings. Marcia's main moment comes in "Juliet is the Sun" (where she becomes convinced she's the newest diva on the Shakespearian theater circuit), while Jan becomes an insufferable egotist in "Miss Popularity." Cindy's time come in "You Can't Win 'Em All."
The fourth-season episode "Today I Am a Freshman" has Marcia wanting to join a group of Alpha Bitches, only to see that they really are bitches and not the girls she wants to associate with. (She gets a little unexpected help from Peter and his model volcano to help her see this.)
Alison from Pretty Little Liars. She has her own Girl Posse - the Liars - and is at the top of the social pyramid. She's willing to do anything to stay there, including blackmail and bribery.
After Alison's death, the position is taken over by Hanna and Mona. Hanna is a Lovable Alpha Bitch who's friends with socially-awkward Lucas and social-outcast Caleb (who she later begins dating) and is generally nice to just about anyone. Mona, however, fits this trope to a T; she even continues many of Ali's mannerisms, such as bullying Lucas by calling him "hermie" (for hermaphrodite) or being generally bitchy to just about anyone, to the point that none of the Liars (except for Hanna) can stand her even prior to her being revealed as the Big Bad.
Libby, who epitomizes this trope so much she was the former Trope Namer. In one episode, she fell from popularity and wound up in the science club. She simply reinvented her look and turned the club into the same sort of clique the cheerleading squad had been. We would occasionally be given hints that Libby wasn't so bad, and that, someday, she might become a good person, but this never happens.
According to one of the tie-in novels, she actually had Presidential aspirations, with a plan and everything. High school was just the beginning.
In the movie version, which preceded the TV series, there's a proto-Alpha Bitch character (played by a different actress) who is blonde and is named Katie.
Heather Chandler in Chuck, played to great effect by Nicole Ritchie, is Sarah's version of this trope, tailored especially for Sarah in this case, as Heather is also a Femme Fatale in addition to still being an Alpha Bitch as a grownup.
She somewhat redeems herself in her second appearance, where she admits she genuinely did try to love her husband, whom she originally married for money, but failed. At the end she sincerely wishes Sarah better luck in her relationship with Chuck.
Paige Michalchuk is, strangely, a Rich Bitch who isn't rich. She's the head cheerleader (who takes credit for other girls' work), and she's a horrendous snob toward anyone less popular than herself. But when school is out, she has to work a minimum-wage job. Paige became a subversion of this trope. While she had a lot of moments setting this trope up, they peppered in Pet the Dog moments to keep her from being irredeemable, mostly with Spinner, Alex, and J.T.
Her replacement after she's graduated is Holly J., who followed this to a T. Rich, pretty, snobbish beyond logic and reason, and mercilessly cruel. However, the trope is subverted as it turns out that the school actually hates her guts. Then, she becomes poor and a Fallen Princess. Before her fall, they gave her a lot of Ice Queen moments, showing that a lot of her issues were a poor role model at home (her sister, Heather Sinclair).
And her replacements are Katie and Marisol. Marisol is this trope played straight, Katie is friendlier but a bit of an Ice Queen and non-confrontational and will usually go with Marisol's plans. More work was put into keeping Katie friendly than Marisol, who has developed a reputation with the fandom.
Stephanie Kaye from the 1980s Degrassi Junior High is a rare case where the Alpha Bitch is one of the protagonists. As a result, she has frequent Pet the Dog moments in between her bullying.
In Heroes, Jackie is a stereotypical example of this trope (although when her karmic retribution comes, it's a bit more severe than growing up to lead an unfulfilled life). The second season has Debbie, who is a copy of Jackie right down to being the blond head cheerleader.
When the series started, the Alpha Bitch was a girl named Jessica (played by Jessica Alba), who would mock and pick on Alex. However, she disappeared after a few episodes because she got a more prominent role in the remake of Flipper, and was replaced by a similar character named Kelly.
A one-shot character who also fit this type was also named Libby, a year before Sabrina. The Freudian Excuse was somewhat subverted; Libby claimed that she has to worry about being popular, and that she really admires Alex, but she was manipulating Alex into feeling sympathy for her, and she wasn't really sensitive or sympathetic at all.
Milton Armatige (and later, Chatworth Osbourne Jr.) are male example of this trope to the main character in The Many Loves Of Dobie Gillis. The female version of this is Thalia Menniger, who is also the Veronica to Zelda Gilroy's Betty.
The killer in the episode "Stand Up and Holler" was one of these. In the present day, she had two failed marriages (and was working on her third) and was desperately clinging to her glory days when she was the most popular girl in school.
Another episode has a former Alpha Bitch from the Fifties, who became caught up in second-wave feminism and eventually became a teacher. Her remorse over her treatment of the victim causes her to give the team a vital clue.
"Sleepover" revolved around a sleepover at the house of a young Alpha Bitch who poached the victim's best friend into her girl posse. She was also a Creepy Child who killed the family pet. Her parents' form of discipline was disturbing to put it nicely.
Maritza from Taina was one of these. She wanted to be an actress too, but she was far more ruthless than Taina and Renee. She even refers to herself as an "Evil Diva" — which you really would agree with. However, there actually are several moments in which Maritza joins forces with Taina and Renee because they each have a common rival, or they want to make money and she would like to be in on it.
Cassie Lynn Nubbles from Family Matters. As Steve Urkel put it, she was "the poster child for useless people".
Cindy Sanders is originally set up as the sweet Girl Next Door, but once she and Sam finally get together, she turns into a shallow, vapid, Republican bitch.
One of the episodes features a transfer student who befriends the Geeks, who try to keep her away from the popular crowd in the fear that she'll become one of these. It doesn't work, and she joins the popular crowd — but later episodes reveal that, despite what the Geeks fear, she's still friendly towards them.
Twist from Spaced, a post-high-school version. Twist is attractive and fashionable, but she works in a dry cleaners and seems to have only one "friend", Daisy, whom she showers with back-handed compliments. Daisy doesn't seem to notice that Twist is an awful friend until the end of the show.
Subverted in Thirty Rock, where Liz Lemon dreads meeting the Alpha Bitch at her Class Reunion. As it turns out, that school's Alpha Bitch was, in fact, a nice popular girl, whereas all of her classmates regarded Liz as a bully because of her cruel putdowns.
Quinn starts out as this, and her only subversion is that she's also deeply religious and president of the celibacy club. She quickly turns into a Fallen Princess when she reveals that she's pregnant and is kicked off the cheerleading squad.
Her former minion Santana thus becomes the new Alpha Bitch. Santana is however a deconstruction of the trope. As she finds out, for all her bitchiness towards everyone, nobody save Britanny likes her. Also, her cruelty comes from her inner torment over being a lesbian who is in love with her best friend.
Meanwhile, Terri is heavily implied to be a former Alpha Bitch and now has an unhappy adulthood because of it.
Oddly enough, although Rachel is nominally the heroine of Glee and (at least in season 1) Quinn's antagonist, within the glee club itself, she actually functions as the Alpha Bitch due to her unrelenting tendency to belittle, disregard, and demean the other members of the club unless forced to behave otherwise (she calls Kurt and Mercedes 'lesser glee clubbers' to their faces, and tells Tina and Mike that if a potential new recruit can dance, their contribution to the club will be 'even more insignificant than it already is', in quick succession in 2x01, and then sends her new rival to a crackhouse instead of the audition). Her specialty is sweetly offering a brutal putdown and justifying it as 'honesty'. While she gets brought down to earth relatively frequently, it never seems to stick.
Season 4 introduces Kitty, basically Quinn 2.0 minus the redeeming qualities.
On Everybody Loves Raymond, there are two competing characters with Alpha Bitch qualities. Marie, the family matriarch has basically been running the family for decades by guilt-tripping them into doing her bidding. Debra, Marie's daughter-in-law tries to assert herself against Marie, initially in a reasonable way but later on by adopting Alpha Bitch qualities herself. Marie's ability to maintain her position as the senior Alpha Bitch causes junior Alpha Bitch Debra to take out her frustrations by asserting herself as the dictator of her own household, often beating or insulting her husband Ray when he attempts to rebel.
Subverted: Paris Geller bullies Rory (and almost everyone else) mostly out of insecurity, has two sidekicks who are taller than she is, but isn't popular and is respected only for her intelligence and dedication. She also gets brought down to earth in later seasons.
Played straight with Francine "Francie" Jarvis, leader of the Puffs, Chilton's "secret" sorority, and senior class president in season 3, who pits her two enemies, Rory and Paris, against each other and subtly manipulates the student council for personal gains.
Deconstructed in Wonderfalls, with Gretchen Speck-Horowitz, the Alpha Bitch from the high school the protagonists, Jaye and Mahondra, attended. She did genuinely mean things in school, but when they meet her again at their reunion, they learn that her bullying wasn't because of nastiness, but because of ignorance (for example, spreading a rumour that a girl with Bell's Palsy was a drunk because she thought she was). She's also trapped in a failed marriage and considers Jaye, who hates her and hadn't spoken to her for years, her only friend.
The Naked Brothers Band has one episode where Nat is trying to work up the nerves to kiss Rosalina. A girl (who, as she often says, is the most popular girl in their school) shows up to watch them do a music video, and makes fun of Nat because he's unable to do it. Rosalina gets a minor Crowning Moment of Awesome when she tells the girl off in front of both her and her posse. The girl's (rather flustered) response is "Y-You can't talk to me like that! I'm the most popular girl in school!" Rosalina responds with a loud "I DON'T CARE!"
Season one of The Sleepover Club had Sara Tiara, and season two had Krystal Beasley.
Banning Miller in the Firefly episode "Shindig" definitely qualifies, complete with posse. She is very satisfyingly put in her place by a distinguished old man in true Gentleman Snarker fashion after she sets her sights upon Kaylee in her store-bought dress.
Kaylee gets her own subtle revenge as well when her immense knowledge of spaceship engines literally makes her the belle of the ball, leaving the Alpha Bitch and her posse alone while all of the men are enthralled by her talking shop.
Rhonda from Sister Sister (played by Bianca Lawson) was 'prom queen three years running' and consistently Alpha Bitchy until the 4th season episode 'You are so Beautiful', where the character is played by male actor Larry Wrentz to imply (to a ridiculous degree) that Rhonda had lost her looks over the summer (along with her bad attitude). The character is never heard from again a la Chuck Cunningham Syndrome.
The BBC TV series New Tricks has an episode where Detective Superintendent Sandra Pulman was afraid to go to her High School re-union, eventually revealing that it was because she was the school Alpha Bitch. A colleague persuaded her to go, assuring her that people forget these things over the years. However, when she arrived, someone had drawn a devil's horns & beard in red lipstick on her photo in the lobby and she left in a hurry!
CSI: Crime Scene Investigation had a very dark use of the Alpha Bitch in the episode "Unleashed". In it, the Homecoming Queen, as well as her cheerleading squad, in retribution for the Homecoming King dumping her for Maria, ended up posting obscene messages towards Maria, the victim of the day, through the internet in huge numbers. If that wasn't enough, they also ended up uploading a viral video of Maria allegedly saying "slut" and "whore" on the web, and managed to post a website featuring Maria's face on a mule claiming that she's a bitch, eventually garnering over 1,000,000 hits. This doesn't end well for Maria at all, as she eventually broke down from this and other extremely tragic circumstances and committed suicide, nearly taking her developing baby with her, had the Las Vegas police not been there, discovered that she was pregnant, and performed a c-section surgery on her. The Alpha Bitch and her friends ended up paying dearly for it by going to jail.
A truly monstrous Alpha Bitch is the Victim of the Week in the CSI: Miami episode "Stoned Cold". She ends up being stoned to death by the parents of the people she tormented.
CSI: New York: a girl named Libby was pretty nasty: she pretended to make friends with homely girls, dolled them up, had her boyfriend take their virginity, wrote all about it online, and gave the girls big necklaces so everyone would know. The sister of one of her victims strangled her, and then part of her house fell on her. Incidentally, that was the second time that week the killer on a CSI show said "I killed them and I'm not sorry" (the other time was on CSI where a kid shot his abusive dad).
Brooke McQueen in Popular, despite Sam's initial beliefs, is not an Alpha Bitch, but more of a Spoiled Sweet. The distinction of Alpha Bitch truly belongs to her nominal second-in-command, the wonderfully Machiavellian Nicole Julian.
Kate on Lizzie McGuire, though some episodes do hint that she's not really that bad, and she does seem to get a little better in the movie. One episode has her break her arm so she can't be head cheerleader anymore, and her replacement, Claire, is even worse.
Taylor from Caitlin's Way, although every once in a while she and Caitlin managed to actually get along.
Doņa Florinda from the Mexican sitcom, El Chavo del ocho, is thought by some to be an older version of this trope.
For the third time on this page, Ethel Hallow in The Worst Witch. Her two younger sisters are quite nice, though. The TV series adds a rich father to exemplify her Alpha Bitch qualities. But in Weirdsister College she mellows out a little. Truth in Television for quite a few high school Alpha Bitches.
In the spin-off series, The New Worst Witch, Belladonna Bindweed is an even nastier example; she's a more malicious Ethel Hallow, without any of Ethel's Freudian Excuses or redeeming qualities.
Community has Megan, played by guest star Hilary Duff in one episode. Subverted when Britta, Annie and Shirley turn Abed into one to counter them. Re-verted when Britta, Annie and Shirley become Alpha Bitches themselves, which leads to Abed insulting them, then getting out of control and insulting everyone at Greendale.
Miu Kazashiro from Kamen Rider Fourze starts out as this trope. But after one of her sidekicks voluntarily turned into a monster and tried to kill her, its revealed that she is a Lovable Alpha Bitch when she forgives said sidekick. She also befriends the main character and joins his club, while she first thought of him as 'trash' said in Gratuitous English .
Raising Hope: Virginia's cousin Delilah is an Alpha Bitch who never grew out of it.
Sadie in Awkward., as well as Becca, who is head of the "Asian Mafia".
Abigail Armstrong or "Abby" of the Australian produced TV series Dance Academy is a highly competitive ballerina that will verbally assail any other student that she sees a threat to her goals sometimes outright sabotaging theirs. Despite all of this the other lead characters still put up with her in a somewhat friendly manner which softens Abigail's harsh personality very slightly. One of the leading male characters has an unconditional crush on Abby. No matter how she treats him he still seems to be in love with the alpha bitch. Abigail considers the other lead females to be her "Frienemies".
In The Finder Willa went to a beach party with a bunch of rich kids. The girls there in one exchange fit this trope and Girl Posse to a T, being catty and snobbish to Willa's more down to earth style of dress. ...Willa then borrowed the Alpha's car on her way out of there.
Dawn Stiles of Smallville is an Alpha Bitch candidate for Prom Queen. She goes from a normal human to a Body Surf mutant and continues to be more interested in popularity (mainly in how people saw her original self while she was still a normal human) and the prom than in anything else.
In GCB the main character (Amanda)is a former Alpha Bitch who moves back to her hometown to rebuild her life and has to deal with the long term effects of her teen behavior.
In Charmed both Phoebe and Piper had to deal with their high school Alpha Bitches at their respective reunions. Piper's initially didn't remember her, gave her back-handed compliments and ordered her around in her own club. Phoebe's was now married to an old flame and taunted her with an old Embarrassing Nickname. It's also hinted that Prue may have been one in school as well - it's mentioned that she was popular, head cheerleader and strung one of Piper's friends along knowing he had a crush on her.
Two of a Kind introduces Jennifer Dilber whom Mary-Kate describes "has her own website at Prissy.com". She displays a few qualities in her first episode but by her next appearance her and Ashley appear to be good friends.
House of Anubis, while having no completely straight examples, had Patricia fall into this at the beginning of season one; she bullied and played nasty tricks on Nina, assuming she had something to do with the disappearance of her best friend. But it came back to her pretty quickly, as her friends abandoned her for Nina, and the hostility stopped after the false initiation trick. Soon she warmed up to Nina completely, and joined Sibuna.
Amber also had shades of this while running against Mara in the school election, this time over the affection of Mick. They made up quickly enough.
