Heidi Turner
Heidi as of Season 20.note 
"Eric!, Hey, I got us chocolate milks!"

Voiced by: Jessica Makinson

A girl in the same class the four boys attend. She was Eric Cartman's girlfriend for a time. Originally just one of the minor female classmates and a part of Wendy and Bebe's group of friends, she became a much more prominent character Season 20 onwards.

    open/close all folders 

  • Ad Hominem: Employs this tactic constantly during her stint as Cartman's Distaff Counterpart. When Theresa briefly snipes at her, Heidi brings up her family's financial state to put her on the defensive; when Kyle attempts to implore the school to make peace, Heidi tells to him shut up and accuses him of "sounding like his mom"; when Kyle rejects his friends' offer to help him search for his missing brother, Heidi accuses him of simply being bitter over being rejected by her. This last one backfires on her, however, as Kyle turns the tables and disgustedly renounces the idea that he would ever feel any attraction for her, kick-starting her Jerkass Realization.
  • Adorkable: How socially awkward and insecure she is grants her this status along with the amount of woobie-ish moments she faces the looming prospect of.
  • All Girls Want Bad Boys: Subverted. Yes she does become Cartman's girlfriend, but only because he was actually very kind to her in Season 20. Thus, she did not like when he he became a Jerkass to her in Season 21 leading to her decision to dump Cartman in "Splatty Tomato".
  • Amicable Exes: Possibly with Kyle in Season 22. They don't seemed to have got back together, but they are shown willing to sit near each other in the music room without showing any hostility during "The Problem With A Poo".
    • Averted with Cartman. After their break-up in "Splatty Tomato" Heidi seems to be avoiding him as much as possible, sitting far away from him during the music room and the school assembly in "The Problem With A Poo". Likewise, Cartman claims to have anxiety in “Buddha Box” because the he can't stand people anymore (including Heidi), possibly still holding her in contempt for breaking up with him.
  • Arc Hero: Of the Cartman-Heidi relationship arc that dominated Seasons 20 and 21. She's the central character in that Story Arc and gets the most Character Development out of anyone there. Unsurprisingly, after the story arc ends she returns to her previous role as a background character.
  • Ascended Extra: Has been around ever since Season 3, but was mostly a background character. However, as the series progressed, she got a fair amount of prominence and speaking roles. In fact, she played a fairly big role in the Season 9 episode "Marjorine". Despite this, however, her personality and limelight had not been fully established until Season 20.
  • The Atoner: After having a Heel Realization she genuinely regrets becoming a female Cartman and breaks up with Cartman because he was a bad influence for her. By Season 22 she seems to be making a sincere effort to improve her life. These efforts includes losing the weight she gained last season and staying far away from Cartman, not wanting his influence to change her again.
  • Awesomeness by Analysis: In Season 20, she is shown to have invented an entire method of cryptographic analysis in order to uncover the identity of skankhunt42. Not bad for a ten-year-old. Taken Up to Eleven when dealing with the issues at SpaceX; she manages to create a source of energy that can power humanity's trip to Mars, and later saves the world from TrollTrace by having done so.
  • Bait-and-Switch: In "Skank Hunt", she looks suicidal when she's shown at the edge of a bridge, but she was really just quitting Twitter and throwing her phone into the river.
  • Became Their Own Antithesis: Contrast the kind, caring, naive, and healthy girl she once was before dating Cartman to the bitter, resentful, bigoted, and fat Jerkass she became while dating him. "Splatty Tomato" in particular points this out.
  • Brainy Brunette: She has brown hair, and is quite smart for someone her age, having found a way to travel to Mars and is been described by Mr. Mackey as the school’s best science student.
  • Bratty Half-Pint: She showed shades of this in Season 9's "Marjorine", in which she throws a fit over her mom inviting the "new girl" to her slumber party.
    Heidi: Mom, I didn't invite her!
  • Break the Cutie: Season 21 has definitely done this to her. She gets constantly mocked by the other girls for having Cartman as her boyfriend, said boyfriend constantly emotionally abuses her, and manipulates her into rejecting the only person (Kyle) who showed her any sympathy this season. It was inevitable that she would go from a Nice Girl to a Gender Flipped version of her boyfriend.
  • Breakout Character: Originally just one of the more minor characters, becoming Cartman's girlfriend has made her extremely popular amongst the fanbase, promoting her status to a major character even obtaining a hat of her own.
  • Broken Bird: She becomes one by Season 21. She failed to stop Skankhunt42 last season, is frequently picked on by the other girls, and is stuck in an emotionally abusive relationship with Cartman. She tries to cope with all of this by becoming a female version of her boyfriend, only to realize how much she has changed from the Nice Girl she was before. Because of this she breaks up with Cartman for good.
  • Broken Hero: Despite getting viciously trolled, shunned by her friends, and mentally abused by Cartman, she still tries her see the best in everyone and goes out of her way to help those in need. That said, she does have her breaking point and becomes Cartman's Distaff Counterpart because of the constant all of the above.
  • Brooding Boy, Gentle Girl: Was the Gentle Girl to Cartman's Brooding Boy.
  • Character Development: Goes from a judgmental Alpha Bitch first shown in "Marjorine" to a humble Nice Girl after quitting twitter and hooking up with Cartman. However, her self-esteem has also drastically decreased making her submissive to Cartman's abuse. This eventually causes her to adopt Cartman's personality making her nastier than she ever was before. However, she learns how much Cartman's influence changed her, which makes her come to her senses and give her the courage to stand up to Cartman, not cull to his demands, and break up with him for good.
  • Characterization Marches On:
    • Was shown to be an Alpha Bitch who picked on the "new girl"note  in "Marjorine" and ridiculed Lisa Berger for her insecurity in "The Hobbit", but as the show entered its 20th season she has been shown to be nicer.
    • She was shown with numerous different parents throughout the series. Even after her properly renamed introduction in "Marjorine" where her parents are revealed, she was still shown with different parents in "Cartoon Wars Part II", "La Petit Tourette", and "Medicinal Fried Chicken".
    • In "Follow That Egg!", she hates Cartman as much as everyone else, and is upset about being paired with him on the egg project.
  • Charles Atlas Superpower: Emoji Analysis lets her see meaningful patterns in absolutely anything, even things she does not understand (such as the engineering problems that need to be overcome in order to reach Mars), to the point of being able to correct the equations herself, by replacing what is to her meaningless data with something else, which lets her know that two lines in the equations are misaligned, and even lets her produce the season's Deus ex Machina.
  • Classical Anti-Hero: While Heidi is a genuinely kind and thoughtful girl, she also has numerous flaws such as naivety, insecurity, and Pride that allowed her to be manipulated by a lot of people, like Cartman. In "Splatty Tomato" Heidi starts to overcome this upon realizing she can't rely on other people to make choices for her, and must learn to make her own decisions, leading to her choice to finally break up with Cartman.
  • Commuting on a Bus: After being a main character in Seasons 20 and 21, her role is greatly reduced in Season 22 where she might make a brief appearance in some episodes while not appearing in others.
  • Coordinated Clothes: In Season 20, she was always shown wearing matching clothes when she was with her boyfriend Cartman.
  • The Corruptible: As of "Doubling Down", Cartman starts slowly turning her into a female version of himself, tricking her into eating unhealthy foods to make her fatter and convincing her that Kyle (and Jews in general) are terrible people (after Kyle nearly convinced her to leave Cartman). Thankfully she learns how listening to Cartman has negatively changed her health so she decides not to believe him anymore after breaking up with him.
  • The Cutie: As a shy, socially timid and naïve girl, she definitely qualifies. Became downplayed after she became a Distaff Counterpart to her Fat Bastard boyfriend, eventually mustered up the courage to confront Cartman's toxic influence, breaking up with him, and gets Demoted to Extra in Season 22 (though she returns to her cute look).
  • A Day in the Limelight: "The Damned" gives her much more focus than almost every other episode in the series combined. In general, Seasons 20 and 21 is this for her; she contributes to those storylines and is important to half of the main cast, especially Cartman, her boyfriend. Not bad for somebody who was lucky to have anything resembling a role aside from being a minor character for 17 years.
  • Deconstructed Character Archetype: Of the Butt-Monkey trope. Heidi goes through numerous hardships throughout Seasons 20 and 21, which includes being cyber bullied by Skankhut42, getting emotionally abused by her boyfriend, and being picked on by her friends. Eventually she snaps and becomes Cartman's Distaff Counterpart deciding to get back at those who have mistreated her.
  • Defrosting Ice Queen: While earlier episodes such as "Follow That Egg!" shown Heidi contemptuous of Cartman, when she becomes promoted to main cast starting in Season 20 and starts dating him, she treats him very kindly. By Season 21, Cartman got irritated by how overly affectionate Heidi is towards him and ends up turning her into a female version of him.
  • Demoted to Extra: In Season 22, Heidi returns to her old role as a background character.
  • Deuteragonist: Her relationship with Cartman in Season 20 and 21 is the focal point for both those seasons and her importance in them is second only to that of her boyfriend.
  • Distaff Counterpart: By Episode 8 of Season 21, she's essentially become a female Cartman, becoming obese and adopting all his prejudices, selfishness, and casual cruelty. This causes her Heel Realization and becomes one of the reasons why she broke up with Cartman in "Splatty Tomato".
  • The Dog Bites Back: Cartman is an asshole who brainwashed her into becoming his Distaff Counterpart. That said, he learns the hard way what the rest of the protagonists have to deal with, and it's obvious she becomes the one who wears the pants in their relationship.
  • Early Installment Character-Design Difference: Used to have black hair, rather than light brown, and flip-flopped between the colors for a while.
  • Earn Your Happy Ending: By Season 22 she’s out of an abusive relationship, has lost all the weight she gained last season and is a Nice Girl again. While she's returns to her old role as a background character, this is probably for the best given how much she suffered as a main character, especially as Cartman's girlfriend.
  • Evil Vegetarian: Not as first, but she still claims to be a vegan after her Took a Level in Jerkass. Subverted because Cartman tricked her into eating meat.

  • Fallen Heroine: Originally one of the kindest characters in South Park and one of the leading heroes in Season 20, by the next season Cartman's influence has turned her into his Distaff Counterpart turning all her kindness into complete jerkassery. She eventually realizes how far she has fallen, when Kyle declares he could never have any feelings for the person she has become.
  • Fat Bitch: Due to Cartman's influence, she becomes both obese and a terrible person by "Moss Piglets". this changes in "Splatty Tomato" and by "A Problem With A Poo" she's no longer fat.
  • Flower in Her Hair: Well its on her hat, but she wears an purple one on the left side of her head.
  • Formerly Fat: By Season 22, she has lost all the fat she gained last season and is now healthy again.
  • Formerly Fit: She was healthy eating a vegan diet. However, Cartman tricked her into eating "Beyond" KFC and "Beyond" Arbys and she became nearly as fat as him. Inverted in Season 22 where she's Formerly Fat.
  • Freudian Excuse Is No Excuse: What Heidi learns at the end of "Splatty Tomato". Even though she suffered a mentally abusive relationship with Eric Cartman, it doesn't mean she can become a horrible person. She decides to end this problem once and for all by breaking up with Cartman for good.
  • The Friend Nobody Likes: After becoming Cartman's Distaff Counterpart, her female friends begin to detest her for her cruel behavior, to the point that Wendy of all people ends up rooting for Cartman when the two have a fist fight.
  • The Friends Who Never Hang: After hooking up with Cartman, she all of the sudden stopped hanging out with the girls and is almost only shown with her boyfriend now. This is probably explanatory though, since she didn't want to get involved with the drama of the gender war that her friends was participating in, and instead wanted to put an end to it alongside Cartman (who felt the same way about said gender war). She returns to the girls after breaking up with Cartman in "Splatty Tomato".
  • Girly Girl with a Tomboy Streak: Heidi is one of the more girly girls, but she also partakes activities, like playing Call of Duty: World at War in the computer lab, watching Terrence and Phillip Netflix premier with the boys, and judging science fairs, which aren't considered to be feminine.
  • Good Counterpart: She becomes this for Eric Cartman. Like Cartman, she was a Fat Jerkass who would use her role as the victim to justify being awful. Unlike him however, Heidi learns how unhealthy this way of thinking is, would take responsibility for her own actions, and has genuinely made positive changes to improve herself.
  • Grew a Spine: After dealing with Cartman's abuse throughout Season 21 and being converted into his Distaff Counterpart, Heidi finally grows her own in "Splatty Tomato" when she makes it clear that they are breaking up for good, even ignoring his suicide threats that originally kept her from leaving.
  • Heel–Face Revolving Door: Has a tendency to switch from a Nice Girl to a Jerkass. She had made her debut in "Rainforest Shmainforest" but wasn't given much characterization making her neutral on the moral spectrum. Then she was given her first major appearance in "Marjorine" where she shows herself to be quite an Alpha Bitch amongst her friends making her a Heel which lasted until "Skank Hunt" which gives her more prominence and becomes much nicer. Then after becoming Cartman's girlfriend and letting his influence turn her into his Distaff Counterpart she becomes a Heel once more in "Moss Piglets" which lasts until "Splatty Tomato" where she gets a Heel Realization and breaks up with Cartman for good making her a Face once more.
  • Heel Realization: After Kyle declares he can never love her current self in Season 21's finale, Heidi begins to look back on how she got to the point of being a female Cartman, realizing how he slowly destroyed her mentally and physically including attempts of murder. Heidi has enough and breaks up with Cartman for good, no longer wishing to be the victim.
  • His Own Worst Enemy: Ultimately, the biggest reason why Heidi becomes a female Cartman isn't actually Cartman but is instead her own Pride. She doesn't want to admit that she made a bad decision dating Cartman, and when her friends mocks her about that matter she chooses to back to Cartman and believe his lies. She eventually realizes that it was her own fault that she deteriorated so much, both physically and mentally, and decides to make the logical decision to break up with Cartman for good.
  • Honor Before Reason: Kyle eventually realizes that the reason she won't break up with Cartman despite the horrible way he treats her is because she doesn't want to have to admit to the other girls that they were right and dating him was a bad idea. When she does, she gets frustrated when the girls go a little too far in teasing Heidi about dating Cartman, which causes her to go back to Cartman and buy his lies. Basically she would rather suffer in an abusive and manipulative relationship than swallow her pride and own up to her mistakes. Thankfully, she does realize how much this way of thinking has changed her, so she decides to finally own up to her mistakes by breaking up with Cartman for good.
  • Honor Thy Abuser: In "Doubling Down" Heidi decide to accept Cartman's abuse and begins to adopt his personality, which leads to her transformation into his Distaff Counterpart. Subverted in "Splatty Tomato" when she learns that its not okay to accept the abuse and adopting said abuser's personality, leading to her decision to dump her abuser.
  • Horrible Judge of Character: Goes with the territory of being Cartman's girlfriend. Though to her credit, Cartman was a genuinely nice boyfriend in the beginning of their relationship. Something she actually points out shortly before breaking up with him for good.
  • Idiot Savant: Played With. She's certainly not an idiot, despite her seeming lack of social skills, but her skills in Emoji Analysis are nothing short of savantlike.
  • I Hate Past Me: Throughout "Splatty Tomato" Heidi constantly switches from fondly remembering her more naive and happier self to showing nothing but bitterness and contempt for her.
  • Informed Attribute: In-universe example. Her boyfriend Cartman was constantly telling her and everyone else how "smart and funny" she was in Season 20. While she is shown to be quite smart, she never really says or does anything funny, which she and other characters pointed out.
  • Informed Deformity: Wendy says that she has a flat butt in "The Hobbit", but much like the rest of the people she insulted, that feature doesn't seem to apply to her and hasn't been looked into any further.
  • Innocent Bigot: Thanks to Cartman, who manages to brainwash her into sharing his anti-Semitism. She still acts sweet and polite to Kyle as she breaks up with him, but he immediately realizes she essentially called him a "dirty Jew." She drops the innocent part by the next episode.
  • It Sucks to Be the Chosen One: Once Cartman convinces everyone that she's their only hope to get to Mars in "Not Funny", she pretty clearly knows that she's been forced into something far beyond her own abilities.
  • Jerkass Realization: In Season 21's finale, Heidi realizes how horrible she has become thanks to Cartman's influence on her in the aforementioned season.
  • Knight of Cerebus: She serves as a non-villainous example. note . Seasons 20 and 21 were definitely less humorous and more story driven and dramatic due to Heidi's importance in them, with her abuse at the hands of Cartman being played dead seriously for the most part, showing the negative effects it had on her mental and physical health. Episodes where she's Out of Focus or doesn't appear in tend to be much more humorous.
  • Lesser of Two Evils: While presented as seemingly "worse" than Cartman, she is in truth this. While she did inherited Cartman's obesity, bigotry, and Jerkass tendencies, she does get a Heel Realization and breaks up with Cartman before he could further corrupt her into inheriting his more twisted traits such as his sadism and sociopathy.
  • Living Prop: Though not completely silent, Heidi was mostly a background character prior to Season 20. She returns to being this in Season 22.
  • Lovable Alpha Bitch: She usually hangs out with the popular girls and has shown to pick on girls less popular than her like Marjorinenote  and Lisa Burger. That said she isn't completely heartless as she did apologize to the former for her behavior, she shows a more kinder and vulnerable side of her personality after quitting twitter and becoming a social outcast.
  • Loving a Shadow: What her feelings for Cartman amounts to. She hooks up with Cartman just because they were both were social outcasts and felt it was better to be victims than face reality. It gets to the point where they both Took a Level in Jerkass in Season 21 because of how much they enjoyed Playing the Victim Card. When Heidi goes back to all the landmarks that brought her and Cartman together in "Splatty Tomato" she realizes that she doesn't truly love Cartman, but liked that he gave her a reason to engage in self-victimization. Because of this she breaks up with Cartman, no longer wanting to be the victim.
  • Meaningful Name: Her last name "Turner" signifies how her appearance, personality, and importance in the show keeps on changing. Her first appearance has her be a background character with black hair and no personality before "turning" her into a brunette with an Alpha Bitch personality in "Majorine", though still seldom used. Then she gets promoted to a main character during Seasons 20 and 21 "turning" into a Nice Girl with a Nice Hat before her boyfriend's influence "turns" her into a Fat Jerkass like him. After breaking up with Cartman and by Season 22 she "turns" back to her old self and is once again a background character, though she still wears her hat.
  • Must Make Amends: Possibly with her girlfriends and Kyle in Season 22. While they aren't seen conversing, given that she's setting near them in the music room and school assembly respectively in "The Problem With A Poo" suggests that she's trying to make amends for mistreating them last season.

  • Nice Hat: Gets a stripped one with a flower on it in "Skank Hunt". She even keeps it after being Demoted to Extra.
  • Nice Girl: Going hand-in-hand with her constant attempts to help people on a large scale, there doesn't seem to be a single person Heidi dislikes. Even Cartman. Especially Cartman. Unfortunately by "Moss Piglets", she has changed, until she has a Heel Realization and breaks up with Cartman.
  • Not Afraid of You Anymore: In contrast to previously taking Cartman back when threatens to kill himself in "Put It Down", she firmly states thats not going to work and leaves when Cartman pull this stunt again in "Splatty Tomato" making it clear to him that this time they are breaking up for good.
  • Odd Friendship: Develops one with Cartman after they both go off Twitter, which eventually evolves into a relationship.
  • Official Couple: With Eric Cartman, of all people. However the relationship ends in “Splatty Tomato” when she breaks up with Cartman for good.
  • Out of Focus: In stark contrast to Seasons 20 and 21, Season 22 arguably gives her the least amount of focus, only making appearances in two out of the ten episodes.
  • Ping-Pong Naïveté: Is smart enough to figure out how to uncover anybody's identity online, and create the energy source required to go to Mars, but doesn't know that showing her private parts to a boy she barely knows is inappropriate behavior. These events happen in the same season.
  • Pink Means Feminine: She wears a pink hat and played the Alpha Bitch role in her earlier appearances, and then The Cutie role when she became an Ascended Extra in Season 20, both of which are typically associated with female characters. She even has a pink bike.
  • Plucky Girl: Despite all the hardships she endured in Seasons 20 and 21, that didn't stop her from reverting back to her old personality, loosing the fat she gained, and getting rid of all the Cartman attributes by Season 22. The fact that she's riding a very girly bike in the bike parade acting like nothing bad has happened to her cements her as this.
  • Politically Incorrect Villain: She starts spewing ableist and classist rhetoric in "Moss Piglets".
  • Pride: The reason why she doesn't want to break up with Cartman, even if she knows he's a bad influence for her. Eventually she learns to forgo her pride upon realizing how much it cost her, both physically and mentally, and breaks up with Cartman.
  • Protagonist Journey to Villain: Season 21 gives the most focus to her deteriorating relationship with Cartman and how it transformed her from a Nice Girl to her boyfriend's Distaff Counterpart. Subverted when she gets a Heel Realization and breaks up with Cartman.
  • Reformed Bully: She was originally an Alpha Bitch who would pick on girls less popular then her, but Season 20 made her a lot more nicer while not showing any signs of her meanness. She does return to her bullying ways after becoming Eric Cartman's Distaff Counterpart, but would break up with him when she realizes he's a bad influence for her and rid herself of any Cartman-like traits by Season 22, making her this trope once more.
  • Reformed, but Rejected: Even though she's back to her old self in Season 22, her girlfriends don't seemed to have forgiven her for her mistreatment of them when she was a female Cartman and are trying to avoid her. This include having one of their acquaintances sit next to her in the school assembly serving as a barrier between her and her quad-let (Wendy, Isla, and Theresa) during "The Problem With A Poo" and not sitting with her during lunch in "The Scoots".
  • Rise of Zitboy: After gaining weight, she now has two pimples on her face, probably caused by all of the grease in the KFC Cartman has been feeding her. Though she looses the zits along with her weight gain by "A Problem With a Poo"
  • Satellite Love Interest: Upon becoming an Ascended Extra during Season 20 and 21, her whole character stems on being Eric Cartman's girlfriend and how her relationship has affect him and herself. After breaking up with Cartman in for the final time in "Splatty Tomato she reverts back to her background character role.
  • Shadow Archetype:
    • To Wendy Testabuger. Both are Brainy Brunettes, had feelings for Eric Cartman, and are the only known female students to wear hats. However, Heidi lacks Wendy's strong will and thus never learned to resolve her feelings for Cartman on her own like Wendy did. As a result, while Wendy was able to keep her positive attributes, lose all her feelings for Cartman, and retain her self-identity, Heidi loses all her attributes and stayed in a romantic relationship with Cartman long enough for his toxic influence to turn her into a female version of himself. Though Heidi does break-up with Cartman, possibly losing all her feelings for him in the process, and was able to reclaim all her attributes by Season 22.
    • She's also one for Butters Stotch. Both are kind and innocent children, whose naivety are constantly exploited by Cartman and are among the few kids to call him Eric. However Butters knows better than to stoop to Cartman's level and remains his kind and innocent self. Heidi doesn't and ends up becoming a Distaff Counterpart to Cartman. Though Heidi does learn like Butters and returns to her old self after breaking up with Cartman.
    • She's also one to a female New Kid, in regards to their contrasting relationships with Cartman. While Heidi's relationship with him is romantic, the New Kid has more of a teacher/student bond with him. Heidi came to Cartman and the two bonded over falling off the social media grid while Cartman went out of his way to be nice to the New Kid and thus earned her loyalty. While Heidi broke up with Cartman after realizing what his influence turned her into, The New Kid had no problems with anything Cartman was having her do, until Cartman betrayed her and kidnapped her parents, causing her to lose all respect for him. While Heidi seems to be actively avoiding Cartman after breaking up with him, The New Kid seems to have forgiven Cartman, willing to hang out with him afterwards.
    • Heidi herself would receive a Shadow Archetype in Mr. Hankey. See here for more details about that.
  • She's Back: By Season 22, she's back to being a normal-sized nice background character.
  • The Smurfette Principle: She is the only female character to ever appear in a DVD box cover.
  • Sour Outside, Sad Inside: Sure she's become the Gender Flipped version of her boyfriend Cartman by "Moss Piglets", but that's because she doesn't want to be constantly abused emotionally by her peers and Cartman, even if it means abusing them herself. This is more explored in "Splatty Tomato" where despite acting horrible, she's just so broken.
  • Stepford Smiler: She may be all bubbly and happy for most of Season 20, but in "Douche and a Danish" she breaks down crying after her plan to help Denmark turns out to be for nothing, suggesting that she doesn't have very good self-esteem.
  • Sudden Name Change: Was originally identified as "Marcy" in "Probably", but was later properly renamed Heidi in "Marjorine".
  • Temporarily a Villain: Her time as a female Cartman, which started in "Moss Piglets" and lasted until "Splatty Tomato".
  • Then Let Me Be Evil: After being picked on by her friends for going out with Cartman, she decides to let him manipulate her and become his Distaff Counterpart. She snaps out of it in "Splatty Tomato".
  • Took a Level in Badass: As of "Splatty Tomato" she has abandoned the victim-mindset and no longer has any problems dumping Cartman.
  • Took a Level in Kindness: Prior to Season 20, she could be unkind to the point of cruelty. After Season 20, however, she's arguably one of the nicest of the 4th grade girls.
    • Happens again after having a Heel Realization and breaking up with Cartman, going from a female Cartman back to her Nice Girl self.
  • Took a Level in Jerkass: By "Moss Piglets" in Season 21, she has become a female version of Cartman. However, it serves more as a defense mechanism to endure all the emotional stress given to her rather than becoming genuinely malicious. When she realizes that she took it too far, she decides to resolve this issue by breaking up with Cartman.
  • Troubled Abuser: After being abused by Cartman for the majority of Season 21, she starts adopting his personality and began abusing him.
  • Unwitting Instigator of Doom: When she gave her "Emoji Analysis" to Lennart Bedrager, she didn't know that he'd use it to cause mass hysteria and a world war.
  • What Have I Become?: After hearing Kyle's Armor-Piercing Response in "Splatty Tomato", she becomes disgusted with herself for becoming Cartman's Distaff Counterpart. At first, she blames Cartman and prepares to kill him for, in her own words, "turning me into this!" However, she soon realizes that it was her "I'm a victim" attitude that resulted in her deteriorated state.
  • Weak-Willed: Her biggest flaw aside from her Pride. She is so insecure of what she that it was very easy for Cartman to convince her into becoming his Distaff Counterpart. Her Character Development involves her becoming more confident in herself leading to her choice to break up with Cartman, thus removing this aspect from her personality.
  • "You!" Exclamation: She gives this to Cartman near the end of "Splatty Tomato".
  • You Killed My Father: Averted. Her father is killed in "Probably" because of Cartman's negligence, but, as shown in Season 20, she doesn't seem to hold it against him, or even remember it. She is shown with different, living, parents in other episodes. Either her mother remarried, or the writers just reused Heidi's character model for generic girls early on.
