!!Main Characters
[[folder:Jennifer Check]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/jennifer_0.jpg]]
->'''Played By''': Creator/MeganFox

* AlasPoorVillain: The fact that Jennifer is possessed shows she's not in complete control of her actions and by doing the ritual on her, [[spoiler:Low Shoulder is pretty much responsible for her death.]] Needy mourns her and may still have feelings for her after killing her, and sets out to avenge her original death.
* AllTakeAndNoGive: As Needy points out, Jennifer is a terrible friend who constantly pushes Needy around and drags her wherever she goes, without considering her feelings or providing any support in return. [[spoiler:Her finally realizing this causes her to let Needy kill her.]]
* AlphaBitch: She's a popular color guarder who's also a ''massive'' bitch, to the point where the other students consider her "evil." Despite this, guys trip over themselves to impress her. She ''does'' have shades of a nicer side, at least at first, but only to Needy. However, Needy says she wasn't a good friend even when they were kids; she would steal her toys and pour lemonade on her bed.
* AmbiguouslyBi: Much like Needy, she shows many traits of this, actually trying to seduce her (and succeeding) at one point. ([[invoked]][[WordOfGod Megan Fox says]] that she played Jennifer as a deeply closeted lesbian.) She also utters this great line:
-->'''Needy:''' I thought you only killed boys!\\
'''Jennifer:''' I go both ways.
* BerserkButton: Don't tell her about [[spoiler:how she had to use laxatives to stay skinny back when she was alive]].
* BigBad: Her boy-eating rampage drives the plot.
* BigBadFriend: She was Needy's ChildhoodFriends and BestFriend before she got possessed.
* BlatantLies: She claims to be a virgin in an attempt to escape from Low Shoulder, with one of the band members even doubting her honesty due to how obviously false that statement is. Unfortunately, Nikolai falls for it.
* BlessedWithSuck: Unlike Needy, who is CursedWithAwesome, Jennifer enjoys her powers but she's also a mangled, evil demon that needs to feed on others to survive.
* BrainyBrunette: Inverted. She's your typical vapid cheerleader, while her blonde best friend Needy is a nerd.
* BreastAttack: Needy stabs her breasts to get to her heart. Jennifer's last words are even "my tit!".
* CruelCheerleader: A cruel, vapid and bitchy cheerleader, and that's before she gets possessed.
* CursedWithAwesome: She seems to think so after becoming possessed by the demon, but in reality it's BlessedWithSuck.
* DecoyProtagonist: Her name may be in the title, but the story is about Needy.
* DepravedBisexual: Possibly. She "go[es] both way" by her own admission, but Megan Fox has stated that she viewed Jennifer as gay. But she still kills and eats people, and even before that, she was a ManipulativeBitch who bullied Needy.
* DrunkOnTheDarkSide: Jennifer really enjoys her new powers after becoming possessed and seems to revel in the murders she commits. She wasn't evil before her change, but her turn to evil does involve the flaws she already had consuming her.
* EnemyToAllLivingThings: Subverted. The animals are ''drawn'' to her due to the scent of death, both from her and of her victims.
* EvenEvilHasLovedOnes: Even at her lowest moments, Jennifer can't quite bring herself to kill Needy. [[spoiler:After Needy rips off Jennifer's friendship necklace, [[MyGodWhatHaveIDone the weight of her actions and how she ruined their friendship finally sinks in]], and she allows Needy to finish her off.]]
* FamilyOfChoice: Where does Jennifer go right after having been sacrificed and killed by Low Shoulder? She doesn't go home, she goes straight to Needy's house. For as bitchy as she was before her transformation, she clearly viewed Needy as someone she could run to if she was in danger.
* FauxAffablyEvil: Following her transformation, any of "kindness" that Jennifer shows towards men is just a means to continue feeding.
* ForTheEvulz: [[spoiler: When she could've eaten any other guy, she killed Chip just to hurt Needy.]]
* FilleFatale: It can be easy to forget because of DawsonCasting, but Jennifer is in her last year of high school and extremely sexually active, including with adult men.
* FriendlyEnemy: Zigzagged towards Needy, kind of. But Needy soon figures out that this is at least partially a pretense because Jennifer still needed to feel superior so she could hurt Needy more.
* GameFace: Jennifer's face transforms into her new demonic visage when she's feeding, or when she's trying to intimidate someone. It mostly involves a MonsterMouth with rows of razor-sharp fangs.
* GigglingVillain: When she is DrunkOnTheDarkSide, particularly during the final act.
* AGodAmI: She tells Needy this when defending her current situation. After realizing her newfound healing ability, Jennifer burns her tongue with a lighter, then loudly declares "I am a god."
* HaveIMentionedIAmHeterosexualToday: It's heavily implied that the reason she sleeps around so much and flirts with boys is to cover up her own feelings for Needy. Megan Fox also said that she played Jennifer as a deeply closeted lesbian, further playing into this.
* HealingFactor: Jennifer can regenerate from any injury, she recovered from being impaled through the stomach, having her tongue burned and having her arm cut with a needle.
* HorrorHunger: She vomits a trail of black, spiny fluid if she eats anything but men. But she does adapt to her new diet very well.
* IconicOutfit: Jennifer likes to sleep in a 3/4-sleeve shirt, short underwear, and either knee-length socks or legwarmers.
* IHaveBoobsYouMustObey: She uses her assets to get drinks despite being underage, and believes that breasts are like smart bombs that give women power.
-->'''Jennifer''':(''when asked how she will get alcohol'') Uh, I'll just play hello titty with the bartender.
* ImAHumanitarian: Post-possession, she has to eat the people she kills. If her attempts at eating a roast chicken are any indication, she literally ''can't'' eat anything else.
* InferioritySuperiorityComplex: Needy outright says in the finale that much of her haughty behavior is a cover for deep insecurities. Jennifer's response shows that such a claim struck a nerve.
* {{Jerkass}}: More so in the post demonic possession, where any HiddenHeartOfGold she'd displayed beforehand has ceased to exist.
* JumpingOffTheSlipperySlope: After her demonic transformation, she's originally horrified with herself. However, she quickly acclimates and even revels in her powers as she continually feeds on men.
* KickTheDog: [[spoiler:She murders Chip just to hurt Needy.]]
* LiteralManeater: She seduces men, luring them in with the promise of sex... and then kills them and eats their remains.
* MsFanservice: She wears very revealing clothing throughout the movie, usually baring her legs and acting very sexually aggressive. She also has a SkinnyDipping scene with a shot of her [[SexySurfacingShot surfacing from the water naked]], although the scene combines FootFocus, ShouldersUpNudity and ToplessnessFromTheBack to hide any of her naughty bits.
* MyDeathIsJustTheBeginning: [[spoiler: In the final fight before her death, Jennifer bites Needy and in doing so transfers some of her demonic spirit and powers to Needy so that she may in a sense still live on through her.]]
* MyGodWhatHaveIDone: [[spoiler: At the end, she is shown to be crying before getting ready for prom, implying that she is feeling a bit remorseful for what she is about to do to Chip.]]
** [[spoiler:During their climactic fight, it seems to finally sink in how much she's hurt her BestFriend when Needy rips off her B.F.F. necklace. She then stops fighting back, allowing Needy to kill her.]]
* {{Narcissist}}: Even prior to her transformation, Jennifer was incredibly vain, shallow, and self-absorbed, often putting her own desires over Needy despite her genuine friendship with her. ''After'' her transformation, all of these traits are amplified to a horrific degree and she becomes an egotistical monster, both figuratively and [[EvilMakesYouMonstrous literally]].
* OddFriendship: Her friendship with Needy is noted to be unusual by both of them, considering Jennifer is an AlphaBitch and Needy is a kindhearted nerd.
* PinkIsErotic: Pink is used predominantly in the film and is associated with Jennifer, a sexually confident teenager who is possessed by a succubus who [[LiteralManeater seduces men so she can eat them]].
* PopularIsDumb: The most popular girl in school, who isn't very smart. [[ObfuscatingStupidity On the surface, at least.]]
* PragmaticVillainy: Initially, she only killed who she needed in order to survive. This goes out the window as she attempts to feed on Chip out of spite.
* PsychoLesbian: Another possible interpretation of Jennifer's behavior. While she does seduce (and kill) boys, she is really only attached to Needy, and her flirtation and hooking up with Needy is contrasted with the lack of enjoyment she gets from boys.
* ReallyGetsAround: Jennifer has been sleeping around since Junior High. When Low Shoulder assumes she's a virgin and tries to use her for a VirginSacrifice, it turns her into a LiteralManeater [[SuccubiAndIncubi Succubus]].
* {{Sadist}}: She quickly begins to enjoy murdering for the sake of it and relishes in the fear she brings her victims.
* SelfMutilationDemonstration: Jennifer burns her own tongue with a cigarette lighter, and slashes herself in front of Needy when she decides to share her 'secret' with her.
* StringyHairedGhostGirl: In one scene, she gains this look in an EtherealWhiteDress and wet, unkempt hair. While not a ghost, It's very similar to this spirit.
* SlasherSmile: Jennifer displays one at various times. [[spoiler:Most notably after she first becomes possessed and when she appears in Needy's vision sitting on top of the chair watching her and Chip have sex.]]
* SoBeautifulItsACurse: Her stigma against boys was because she was treated as a sex object and ([[WordOfGod according to Megan Fox]]) she played up the sex appeal in order to conceal her feelings for Needy. [[spoiler:Low Shoulder sacrificed Jennifer under the belief she was a virgin and her body was possessed a succubus, a being that saw her as the perfect vessel due to her beauty.]]
* SuccubiAndIncubi: Jennifer turns into a type of succubus after she's sacrificed by Nikola, supposedly due to them trying to do a VirginSacrifice but her ''not'' being a virgin. As a Succubus she becomes a demonic sexual predator who seduces human men in order to devour them as a LiteralManeater, which is the [[HorrorHunger only way a succubus can sustain themselves]], thus preserving their HealingFactor and [[SuperStrength enhanced strength]]. Her appearance doesn't change, except when she's preparing to devour her victims, which causes her to get a demonic GameFace with a MonsterMouth.
* StrawFeminist: Jennifer has a bit of this trait, claiming that PMS was invented by "boy-run media to make (women) seem crazy". An unused exchange between her and Needy also has her trying to justify her murders thus:
--->'''Needy:''' You're killing people!\\
'''Jennifer:''' No, I'm killing ''boys''.
* TragicVillain: A textbook case where things beyond her control ''and'' her own fatal flaws prove her undoing. While initially a stuck-up AlphaBitch, she is genuinely terrified for her life when Low Shoulder try to sacrifice her. As a result of her DemonicPossession, she is initially forced to kill and devour people to survive, while her toxic traits seem to amplify. Even after killing her, Needy still remembers Jennifer as the friend she lost before all this happened.
* UsedToBeASweetKid: Childhood {{flashback}}s show Jennifer and Needy as innocent children playing in the sandbox, which Needy flashes back to as she stabs Jennifer's heart.
--> ''Sandbox love never dies.''
* VillainProtagonist: She's the film's main character other than Needy, and minutes into it she becomes a LiteralManeater that wants to devour every boy in her school.
* VitriolicBestBuds: She and Chip take snipes at each other, but Chip still ultimately considers her a friend and is immediately willing to let her be his rebound girl after Needy breaks up with him. Jennifer might have also felt something for him before becoming a monster.

[[folder:Anita "Needy" Lesnicki]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/anita_needy_lesnicki.jpg]]
->'''Played By''': Creator/AmandaSeyfried

* AmbiguouslyBi: She is in a romantic relationship with Chip, and clearly cares about him very deeply. She also makes out with Jennifer, and seems to be really into it before she breaks it off. It's heavily implied her feelings for Jennifer borders onto the romantic.
* AvengingTheVillain: [[spoiler:After killing Jennnifer, she absorbs some of her powers and uses them to track down and slaughter Low Shoulder for what they did to her friend.]]
* BecameTheirOwnAntithesis: [[spoiler: She ends the film having become just like Jennifer, demonic man-slaughtering powers and everything.]]

* BewareTheNiceOnes: She's very sweet-natured and lovable but is not to be messed with as Jennifer finds out the hard way.
* BreakTheCutie: She starts as a kind but insecure ShrinkingViolet, then has to deal with her best friend transforming into a monstrous demon, people around her dying, [[spoiler:losing her boyfriend, then finally having to kill Jennifer and being locked up in a mental ward. Fortunately, she ends up gaining Jennifer's demon powers and decides to do something about it.]]
* TheCassandra: She tries to tell everyone over and over that Jennifer is a monster, both before and after her death, and even after that, she tries to convince the psych ward staff about the devil sacrifice. Nobody believes her.
* CursedWithAwesome: When Needy [[spoiler:kills Jennifer, she gains some of her powers, which boils down to: all the good ones, none of the bad.]] However, unlike Jennifer, Needy doesn't relish them but uses them to get her job done.
* DumbBlonde: Inverted. She's [[TheSmartGuy incredibly smart]], in contrast with her [[PopularIsDumb dumb popular]] and brunette friend Jennifer.
* HeroWithBadPublicity: [[spoiler:After killing Jennifer, she's seen by the public as a murderer and locked away when she tries to reveal the truth. After escaping and taking revenge on Nikolai and his band (who are still seen as [[VillainWithGoodPublicity public heroes]]), it's implied she becomes a fugitive afterwards.]]
* HollywoodHomely: {{Invoked}}. Needy has to be more plain around Jennifer.

* NiceGirl: Generally a kind and sweet-natured person, especially when compared to [[AlphaBitch Jennifer]].
* OhCrap: In the Unrated version, she is the first one besides Nikolai to notice the fire starting at the bar, and watches it spread in stunned silence. In the script, she almost catches onto Nikolai when she sees him smirking as the fire spreads.
* OneHeroHoldTheWeaksauce: [[spoiler: She ends the film with powers similar to Jennifer's but without the physical transformation or need to feed.]]
* OnlyKnownByTheirNickname: No one ever calls her "Anita."
* RoaringRampageOfRevenge: [[spoiler:She slaughters Low Shoulder at the end of the movie for what they turned Jennifer into.]]
* ShipperOnDeck: She ships Jennifer/Colin, and encourages Jennifer to go out with him. [[UnwittingInstigatorOfDoom This doesn't end well.]]
* SupportingProtagonist: She's TheHero of the film, but still takes a secondary role to VillainProtagonist Jennifer.
* TookALevelInBadass: [[spoiler:After gaining part of Jennifer's powers, she breaks out and massacres all of Low Shoulder.]]
* TookALevelInJerkass: She becomes extremely violent and unstable after being [[BrokenBird well and truly broken]]. The HowWeGotHere opening has her kicking an orderly (whose only "crime" was to chastise Needy for her choice of food) so hard she knocks one of her teeth out.
-->'''Needy:''' I recommend that you shut the fuck up!

->'''Played By''': Creator/JohnnySimmons

* CharacterDeath: The last of Jennifer's victims.
* [[ClingyJealousGirl Clingy Jealous Guy]]: He's very possessive of Needy, being jealous of her relationship with both Jennifer and Colin. However Jennifer is shown to be a ToxicFriendInfluence, meaning his criticisms about Needy's relationship with her is valid and he does genuienly love Needy.
* DiedInYourArmsTonight: He dies in Needy's arms after Jennifer tore his neck open.
* DoggedNiceGuy: A positive version, but he is very possessive of Needy and jealous of her friendship with Colin.
* DyingMomentOfAwesome: [[spoiler:Chip's [[ImpaledWithExtremePrejudice impalement]] of Jennifer.]]
* FaceDeathWithDignity: He impales Jennifer, which fails to kill her, but he still gets serious points for trying, and then, as he lies dying, he uses his last moments to try and comfort Needy, telling her that he loves her, and peacefully accepting that it's his time to go.
* NiceGuy: He's kind and supportive of Needy, and seems to get along well with everyone except Jennifer, which isn't for lack of trying on his part and is almost [[AlphaBitch totally on her]].
* SacrificialLion: His death is what makes Needy finally, really commit to killing Jennifer for once and all.
* VitriolicBestBuds: He and Jennifer take snipes at each other, but Chip still ultimately considers her a friend and is immediately willing to let her be his rebound girl after Needy breaks up with him, though soon after backs out since it "feels weird". Jennifer might have also felt something for him before becoming a monster.

[[folder:Nikolai Wolf]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/nikolai_wolf.jpg]]
->'''Played By''': Creator/AdamBrody

* AssholeVictim: [[spoiler:Needy violently kills him with the same knife he used to kill Jennifer.]]
* BitchInSheepsClothing: He has Adam Brody's charm and is a vile monster underneath.
* DealWithTheDevil: He sacrifices Jennifer to Satan in order to achieve fame. It works, [[spoiler:but that doesn't stop Needy from stabbing him death [[ExactWords after the fact]]]].
* FauxAffablyEvil: He can be exceptionally charming and charismatic, as one would expect from the front man of a band, but it's all an act.
* GreaterScopeVillain: His HumanSacrifice of Jennifer made her what she became.
* HateSink: He's an arrogant, misogynistic, sadistic, devil-worshipping prick without a single redeeming quality.
* HoistByHisOwnPetard: Killed by Needy with the same knife he used to sacrifice Jennifer.
* HollywoodSatanism: Practices human sacrifice in Satan's name to get a record deal, it's heavily implied that he practices dark magic, especially in the movies script.
* HorribleJudgeOfCharacter: He believes Jennifer to be a virgin after their first conversation. [[ReallyGetsAround This is blatantly not true]], to the point that even one of his bandmates comments on how unlikely that is, yet Nikolai ignores his warnings.
* {{Jerkass}}: Even beyond his obvious evil deeds of killing an innocent girl for a record deal, he and his band go out of their way to mock Jennifer as she's dying, seemingly for no other reason than they feel like it.
* KarmaHoudiniWarranty: He and his band get away with both starting the fire at the bar and their murder of Jennifer, becoming heroes in the public eye and boosting their success as a result. [[spoiler: Then Needy comes calling, with the demonic powers their ritual had given Jennifer now inside of her, to kill them all as vengeance.]]
* KickTheDog: Before killing Jennifer, he makes sure to lead his band in a song while doing so just to mock her.
* TheLeader: Of his indie rock band, "Low Shoulder".
* ObviouslyEvil: Needy knows there is something up with him the minute she overhears him talking about Jennifer; her narration strait up a describes him as evil as he lures Jennifer to his van, especially with all his knowing smiles during the fire. Despite this he remains a VillainWithGoodPublicity throughout. In the script, she spots his PsychoticSmirk coinciding with her OhCrap moment during the fire, and nearly puts two and two together.
* NamesToRunAwayFromReallyFast: Who would've guessed that "Nikolai Wolf" is a villain?
* ReligionOfEvil: He and his band are Satan worshipers.
* RockMeAsmodeus: His group is a parody in the form of an {{emo}} band called Low Shoulder. The song "[[https://www.youtube.com/watch?v=R3DqfXq690I Through the Trees]]" is pure 2000s pop-emo as its most sensitive and lovelorn, while the band's members use their personas as sensitive {{nice guy}}s to pick up chicks.
* SmugSnake: Is always seen with a calm and proud demeanour, almost always on top of every situation, especially with his knowing PsychoticSmirk as his fire spreads.
* TheSociopath: On top of his blatantly shallow charisma, Nikolai has no concept of empathy and sees nothing wrong with sacrificing an entire building full of people or a teenage girl to achieve his goals.
* StupidEvil: He falls for Jennifer's claims of [[BlatantLies being a virgin]] and doesn't seem to realize that making a DealWithTheDevil might not be a good idea in the long run.
* VillainWithGoodPublicity: The band became local heroes in town for "helping people" escape the fire at the bar, despite them being the ones that caused it in the first place.
* VillainSong: Inverted. His hit "''Through The Trees''" is a life affirming song about overcoming loss, and becomes the anthem of Devils Kettle after their show catches fire. It is also the song he sings to keep his audience entranced during said fire.
* VirginSacrifice: A Satan worshiper that was looking for a virgin to sacrifice to Satan so he and his band could cut a record deal.

* SternTeacher: The stern science teacher at Devil's Kettle school, he's rightly indignant over Jenniver's dismissive attitude toward the deceased, but lumps Needy into the same comment.
