!The Plastics


[[folder: As a Whole]]

* BlondeBrunetteRedhead: After Cady enters, and especially after [[spoiler:Regina leaves]].
* FourTemperamentEnsemble: Cady (phlegmatic), Regina (choleric), Gretchen (melancholic), and Karen (sanguine).
* GirlPosse: They're the titular mean girls that rule the school.
* LargeAndInCharge: The two dominant members (Cady and Regina) are noticably taller than the two followers (Gretchen and Karen.)
* PoliticallyIncorrectVillain: They have no qualms about branding Janis a "dyke," and Regina uses the word "retarded" casually in her first on-screen conversation.
* PopularIsDumb: Played straight with Gretchen and Karen (''especially'' Karen). Zig-zagged with Regina who despite being able to manipulate most of the female half of the school into becoming her pawns, frequently shows herself to be rather BookDumb.
** Discussed and justified over the course of the movie--Cady, during her [[BecomingTheMask evolution into the]] AlphaBitch, begins [[ObfuscatingStupidity dumbing herself down]] so a boy will like her.
* SexySantaDress: In their "Jingle Bell Rock" routine that they do for the Winter Talent Show (which, according to [[GayBestFriend Damien]], they do every year).

[[folder: Cady Heron]]

!!Cady Heron (Creator/LindsayLohan)

-->'''Cady:''' ''Calling somebody else fat won't make you any skinnier. Calling someone stupid doesn't make you any smarter. And ruining Regina George's life definitely didn't make me any happier. All you can do in life is try to solve the problem in front of you.''

[[caption-width-right:250:"I know it looked like I was being a [[AlphaBitch bitch]], but that's only because I was ''[[BeneathTheMask acting]]'' [[BecomingTheMask like a bitch."]]]]

* AlphaBitch: After BecomingTheMask
* BecomingTheMask: She pretends to be an AlphaBitch to get on Regina's good side. Then she really becomes one.
* BeneathTheMask: She's just as capable of being a bitch as anyone.
* DidIJustSayThatOutLoud: The "word vomit" is a recurring problem for her.
* DiggingYourselfDeeper: Cady refers to this as "word vomit" and can't help herself once it starts.
* EatingLunchAlone: On her first day at school, she ends up eating lunch in a bathroom stall because she doesn't know anyone. After everything blows up in her face, she eats lunch in the bathroom again because ''everyone'' knows her, and they hate her.
* FaceHeelTurn: Over the course of the film, the friendly and good-hearted Cady usurps Regina's position and becomes the mean-spirited AlphaBitch of the school. She goes through a subsequent HeelFaceTurn when she's confronted with her actions.
%%* FieryRedhead
* FishOutOfWater: To the point where Regina describes her as both "like a Martian" and "socially retarded and weird."
* FromNobodyToNightmare: From an awkward NaiveNewcomer to the school's AlphaBitch.
* GoodWithNumbers: Math is her favorite subject.
* HeWhoFightsMonsters: After a while, Cady is no longer pretending to be like the plastics, she's genuinely acting like one.
* HomeSchooledKids: Until the beginning of the movie, Cady had never gone to a regular school and had been homeschooled since she was around four years old.
* TheMole: Janis convinces her to infiltrate the Plastics so she can spy on Regina and take petty revenges on her.
* NaiveNewcomer: She has no clue how to function or fit into the social climbs of highscool. She's taken under Janis's wing, and then Regina's.
* NerdsAreSexy: Zigzagged. Kevin likes her because of her looks ''and'' her math skills. Regina and Damian both tell her joining the mathletes is social suicide and she dumbs herself down to impress Aaron.
* NoSocialSkills: Being homeschooled on a different continent makes for a serious lack of understanding how highschool politics work.
* RedHeadedHeroine: She's the redheaded protagonist.
* ObfuscatingStupidity: She pretends to be terrible at math so that she can study with Aaron.
* ThePawn: For Janis to use to ruin Regina George's life.
* TheStarscream: To Regina.
* TookALevelInJerkass: The more she spends time with the Plastics.
* TragicHero: Actually manages to be a near-textbook example.

[[folder: Regina George]]

!!Regina George (Creator/RachelMcAdams)
[[caption-width-right:250:"You know what people say about you? They say that you're a homeschooled jungle freak who's a less hot version of me!"]]
-->'''Janis''': ''And evil takes a human form in Regina George. Don't be fooled because she may seem like your typical selfish, back-stabbing slut faced ho-bag, but in reality, she's so much more than that.''
-->'''Damian''': ''She's the queen bee - the star, those other two are just her little workers.''

* AlphaBitch: The leader of the Plastics.
* BigBad: Presented as one by Janis. Turns out she's just one of ''many'' mean girls around, including Janis.
* BitchInSheepsClothing: Although she doesn't bother with it for long she can seem nice enough at first if she wants to.
* BlondesAreEvil: Blonde, gorgeous, and evil to the core.
* ButtMonkey: Regina George, the butt of all of Cady's tricks and pranks. [[{{Jerkass}} She probably deserves it, though.]]
* TheChessmaster: Comes up with her plan to get revenge on Cady and throw the entire school into chaos in the course of one screaming car ride home.
* CrocodileTears: Regina sheds these to Principal Duvall when she turns in the burn book and shows him what the other girls "wrote" about her.
* EvenTheGirlsWantHer: Some of the devotion showed by other girls borders on LesYay. She starts a rumor (albeit an untrue one) that Janis had a huge crush on her.
* HeelFaceTurn: At the end.
* HiddenDepths: Oddly enough, she seemed genuinely surprised and hurt when she realizes how much her schoolmates and even her teachers dislike her.
* {{Jerkass}}: In the beginning to the middle of the movie. She then becomes a...
* JerkWithAHeartOfGold: At the near end of the film.
%%* LargeHam
* LovableAlphaBitch: Post HeelFaceTurn (made much more apparent in the original script.)
* ManipulativeBitch: She's extremely skilled at twisting people's words and actions to get what she wants, or even just a cheap laugh.
* MeaningfulName: "Regina" means "queen".
* RichBitch: Huge house, endless wardrobe, cute convertible.
* RichInDollarsPoorInSense: Regina's a specific example. She could rattle off several mostly-illegal weight loss drugs (most of which either were expensive before being banned or would be expensive to ship from countries where they're still legal). Yet, she didn't know enough about health and nutrition to know whether or not butter is a carb. This is most likely a jab at the stereotype of American teenage girls wanting to get thin or in shape the fast and ''un''healthy way than through actual ''healthy'' living.
* ShroudedInMyth: An interview montage with other students and even some faculty highlights the silliest myths and rumors about how cool/mean Regina is.
* SmugSnake: Regina is ''damn'' proud of every little manipulation that she pulls off.
* SpoiledBrat: She regularly tells her mother to shut up or leave her alone. She also has the master suite in her house because she forced her parents to switch rooms with her.
* TokenEvilTeammate: The only one of the titular Mean Girls who is a ''true'' Mean Girl.
* TwistingTheWords:
--> '''Regina''': You're, like, really pretty.
--> '''Cady''': Thanks.
--> '''Regina''': So you agree?
--> '''Cady''': What?
--> '''Regina''': You think you're really pretty?
* VillainousBreakdown:
** When she realizes that Cady deliberately made her gain weight. But then she recovers almost immediately and turns right back into the Chessmaster.
** After Janis humiliates her in front of the school by revealing her ploy with Cady, Regina begins suffering another breakdown. This time, it is cut short [[spoiler: [[LookBothWays by a school bus]]]].

[[folder: Gretchen Weiners]]

!!Gretchen Weiners (Creator/LaceyChabert)
[[caption-width-right:250:"That is so fetch!"]]
-->'''Janis''': ''Gretchen Wieners knows everybody's business, she knows everything about everyone.''
-->'''Damian''': ''That's why her hair is so big, it's full of secrets.''

* BetaBitch: She appears to be this to Regina initially.
* CatchPhrase: She desperately wants to start one: "That is so fetch!"
* EveryoneIsChristianAtChristmas: Despite the fact that Gretchen's Jewish, she performs Jingle Bell Rock, which is a Christmas song, with the other Plastics every year for the Winter Talent Show.
* ExtremeDoormat: She lives to do Regina's bidding. Even after the breakup of the Plastics, she doesn't seem to be able to function without someone to tell her what to do, and finds another queen bee to serve.
* ForcedMeme: Fetch just isn't going to happen.
* GossipyHens: She's the gossip queen, see the quote above.
* HeelFaceTurn: At the end.
* HeterosexualLifePartners: With Karen.
* HiddenDepths: She [[spoiler: confesses to Cady that she's secretly miserable as Regina's friend and has to pretend to like and not like certain things in order to gain Regina's approval]].
* InformedJudaism: At one point, she mentions receiving Hanukkah presents from her parents.
* MinionWithAnFInEvil: Not as much as Karen, but still rather incompetent in bitchiness and actually seems [[LovableAlphaBitch fairly nice]].
* MixedAncestry: She's Jewish, but joins the Cool Asians at the end of the movie.
* {{Neologizer}}: Primarily in the form of "fetch". Which will never catch on.
* ProudBeauty: She acknowledges her beauty when she "apologizes" to the other girls for her behavior.
* ScrewTheRulesIHaveMoney: Gretchen's ticket into the Plastics is that she's rich. When they get called to the principal's office for the burn book, she specifically tries to use her money and her father's notoriety to get out of trouble.
* SoBeautifulItsACurse: "I'm sorry that people are so jealous of me. But I can't help it that I'm popular."
* StepfordSmiler: Gretchen seems to be happy as Regina's second in command, but as Cady begins to chip away her facade we see a nervous mess that is just one more slight away from a full breakdown.
* VillainousBreakdown: '''"WE SHOULD TOTALLY JUST''' '''''STAB CAESAR!!!"'''''
* YesMan: At first to Regina, then Cady, and finally finds a new Queen Bee at the end of the movie, Trang Pak.

[[folder: Karen Smith]]

!!Karen Smith (Creator/AmandaSeyfried)
[[caption-width-right:250:"So if you're from Africa... why are you white?"]]
-->'''Janis''': ''That one there, that's Karen Smith. She is one of the dumbest girls you will ever meet. Damien sat next to her in English last year.''
-->'''Damian''': ''She asked me how to spell orange. ''

* AdvertisedExtra: Karen doesn't have that large of a part (especially compared to the other three plastics) and has little impact on the plot, but is featured in all of the advertisements because she is a Plastic and thus one of the Mean Girls.
* BlondesAreEvil: Subverted; she's pretty nice mostly and is easily the least malicious of the Plastics (Cady included.)
* BrainlessBeauty: One of the iconic examples!
* {{Cloudcuckoolander}}: She's convinced she has psychic powers... you know, a fifth sense? ESPN? Well, at least her boobs do. They can predict when it's going to rain... well when it ''is'' raining.
* TheDitz: Stands in the rain, feeling her breasts (see InformedAbility below), and declares that "there's a 30% chance that it's already raining!" With complete sincerity.
* DumbBlonde: A classic example with shades of old Marilyn Monroe roles where she's just as sweet as she is dumb.
* DumbIsGood: She's the nicer members of the Plastics but also the dumbest.
* GoodBadGirl: See ReallyGetsAround.
* HeelFaceTurn: At the end.
* HeterosexualLifePartners: With Gretchen.
* InformedAbility: Apparently, her breasts can tell when it's going to rain. Or at least, when it's ''already'' raining. And even then, she's not ''completely'' sure, even if she's actually OUTSIDE in the rain.
* KindHeartedSimpleton: While she's not the smartest, she's made up from being the nicest even before her HeelFaceTurn.
* KissingCousins: Gretchen is highly disturbed when Karen boasts about what a good kisser her own cousin is.
-->'''Karen''': You know who's looking fine tonight? Seth Mosakowski.
-->'''Gretchen''': Okay, you did not just say that.
-->'''Karen''': What? He's a good kisser.
-->'''Gretchen''': He's your cousin.
-->'''Karen''': Yeah, but he's my first cousin.
-->'''Gretchen''': Right.
-->'''Karen''': So, you have your cousins, and then you have your first cousins, and then you have your second cousins...
-->'''Gretchen''': No, honey, uh-uh.
-->'''Karen''': That's not right, is it?
-->'''Gretchen''': That is ''so'' not right.
* MinionWithAnFInEvil: There doesn't see to be a mean bone in her body. When she does unkind things, she's usually just following the lead of one of the other girls.
* PerpetualSmiler: Moments she isn't smiling are incredibly short lived.
* ThePollyanna: As well as being the least malicious Plastic she's easily the happiest too, lacking Regina's rage, Gretchen's crippling neurose, or Cady's need to fit in. She's even aware of (and comfortable with) the knowledge she's not very bright.
* ReallyGetsAround: Somewhat of an InformedFlaw, but she has a reputation and is perfectly willing to hook up with her cousin.
* SatelliteCharacter: She's not as fleshed out a character as the other Plastics, she mostly just rounds out the PowerTrio and provides comic relief.
* TokenGoodTeammate: She is the only one who isn't mean-spirited and did things out of naivete rather than malice.

!Other Students

[[folder: Janis Ian]]

!!Janis Ian (Creator/LizzyCaplan)

[[caption-width-right:250:"There are two kinds of evil people in this world. Those who do evil stuff and those who see evil stuff being done and don't try to stop it."]]
-->'''Cady''': ''You know what? You're the one who made me like this so you could use me for your 8th grade revenge!''
-->'''Janis''': ''God! See, at least me and Regina George know we're mean! You try to act so innocent like, "Oh, I use to live in Africa with all the little birdies, and the little monkeys! [...] you are a mean girl! You're a bitch!''

* AmbiguouslyGay: Is Janis Ian a lesbian? Damn hard to say. [[spoiler: It's proven she's not a lesbian when she starts dating [[ProudToBeAGeek Kevin]] at the end of the movie]].

* HeelFaceTurn: At the end.

%%* JerkWithAHeartOfGold
* KarmaHoudini: Janis, who, despite influencing and encouraging Cady to join the Plastics specifically to damage Regina, gets zero comeuppance when she reveals it to the entire crowd of girls following the revelation of the Burn Book.
* ManipulativeBitch: Janis convinces Cady to join the Plastics just so she can information from them.
* MasculineGirlFeminineBoy: Masculine Girl to Damian's Feminine Boy.
* NotSoDifferent: Aside from her JerkWithAHeartOfGold tendencies and her want for revenge against Regina, [[YouAreWhatYouHate she's just as spiteful and manipulative as she is when it comes to Cady]].
* PayEvilUntoEvil: Her vendetta against Regina.
* PlatonicLifePartners: With Damian.
* TheSnarkKnight: No one is safe from her razor sharp snark, not even her BFF Damien.
* VillainousBreakdown: When she realizes that Cady has [[BecomingTheMask become the mask]].

[[folder: Damian]]

!!Damian (Daniel Franzese)
[[caption-width-right:250:"And I want my pink shirt back. I WANT MY PINK SHIRT BACK!"]]
-->'''Damian''': ''"Too gay to function?"''
-->'''Janis''': ''Hey! That's only OK when ''I'' say it.''

* CampGay: Damian is "too gay to function," though to be fair he's only ''mildly'' flamboyant.
* DeadpanSnarker: He's a typical, snakry, gay best friend.
* TheDragon: To Janis.
* GayBestFriend: To Janis and later, Cady.
* HaveIMentionedIAmGay: Too gay to function, to be specific. However, it's only funny when Janis says it.
* MasculineGirlFeminineBoy: Feminine Boy to Janis' Masculine Girl.

[[caption-width-right:250:"You girls have got to stop calling each other sluts and whores, because if you do, it makes it okay for ''guys'' to call you sluts and whores."]]
-->'''Ms. Norbury''': ''I know having a boyfriend might seem like the only thing important to you right now, but you don't have to dumb yourself down in order for a guy to like you.''

* BrainyBrunette: She's the school's math teacher.
* BrokenBird: She's fresh off a divorce and you can see she's still fragile from it.
* CoolTeacher: She's young and genuinely cares about her students. Once Cady stops being a plastic, she starts realizing how cool Ms. Norbury actually is.
-->'''Cady''': ''(stating why she can't go to the dance)'' I'm grounded.
-->'''Norbury''': You're already out.
* ClearMyName: During the intervention, she confronts Cady and asks if there's anything specific she would like to confess. Cady refuses. Ms. Norbury ends up the subject of a police investigation as a consequence.
* DisappointedInYou: Says this word-for-word when Cady initially refuses to admit she wrote the "drug pusher" page in the Burn Book.
* DroppedGlasses: Happens after someone bumps her while she's trying to break up the fights where they inevitably get stepped on.
* CreatorCameo: Played by writer Creator/TinaFey.
* HotTeacher: Young and attractive, she's obviously caught Principal Duvall's eye.
* Meganekko: Comes with being played by Creator/TinaFey.
* ReasonableAuthorityFigure: She's a fountain of good advice for the students (even though they rarely listen to her) and she genuinely cares about both their grades, and their worth as human beings.

[[folder:Principal Duvall]]

!!Principal Duvall (Tim Meadows)
[[caption-width-right:250:"Aw, ''hell no'', I did ''not'' leave the Southside for ''this''!"]]

-->'''Principal Duvall''': ''I just wanted to say that you're all winners. And that I couldn't be happier the school year is ending.''

* BatterUp: When he discovers the students are fighting, [[LetsGetDangerous he grabs his baseball bat]] before going out and breaking up the commotion.
* BewareTheNiceOnes: He looks like he can handle himself in a fight and it's suggested he grew up a rough neighborhood.
-->"Aw ''hell'' no, I did not leave the Southside for ''this!''
* ButtMonkey: He's the head of a school that's the ground for a war between the Plastics and Janis. Naturally, he takes a lot of shit.
* LetsGetDangerous: He normally appears to be an easygoing guy, but when an all-out brawl breaks out in the hallway, he grabs a baseball bat and goes out into the thick of it to break it up himself, pulling a fire alarm and ordering all the girls into the gym. [[BewareTheNiceOnes Needless to say, no one argues.]]
* ReasonableAuthorityFigure: He cares about his students, he just can't do the squishy girly things.
* ShipTease: Has a fairly obvious crush on Miss Norbury.
* TranquilFury: When he starts talking loud and authoritative, everyone listens up.
