Heidi Turner

Bebe has long, blonde hair. She wears a red jacket over a red polo shirt, dark green pants, and gray gloves. In her first appearance, she wore a green jacket, brown pants, and blue gloves.
Bebe is the most popular girl in school. She has great leadership skills and is influential among the other girls at her school.
Although Bebe can sometimes be superficial, preoccupied with appearance and popularity, she resents being considered intelligent simply because she has larger breasts. She envisions herself as a lawyer or marine biologist, so her ambitions extend beyond makeup, fashion, and parties, though these are certainly important aspects of her life.

Cartman is described in several terms; in short, he is an evil, vicious, angry, self-absorbed, immature, destructive, sarcastic, boastful, gap-mouthed, lazy, and demented child—the most unpleasant. He is also racist and stereotypes almost everyone he sees. The dark and generally disturbing tones of his personality often point to extreme mental imbalance. In addition to being portrayed as having a general lack of moral responsibility or social conscience, he also seems to take pleasure in the misfortune of others and is generally incapable of showing empathy, although there have been exceptions. Despite the severity of his actions, they are likely a kind of emotional defense mechanism against his insecurity and (potential) confused sexuality. This "defense," however, does not appear to be impenetrable, as evidenced by the "1%." This has also been parodied, in the cliché of a typical villain who is becoming benevolent.

Cartman is an overweight boy who wears a red jacket, yellow gloves, a blue hat with a yellow puff on it, brown pants, black shoes, and white socks. Sometimes he wears a green t-shirt with a picture of the bear under his jacket, a white t-shirt, and occasionally a dark red t-shirt. He has medium-length brown hair and a double chin. He also has triangular eyebrows, in contrast to the rectangular eyebrows of the other main boys. Although Cartman is overweight, he always denies it, saying, "I'm not fat, I'm just chubby," or some variation of it.

Eric Cartman:
After ending her relationship with Kyle
Heidi struggles with her conscience regarding her relationship with Eric. As they walk through the woods with the boys, they pass iconic locations from the previous season, including the bridge where Heidi threw her phone away after quitting social media. She reminisces about and re-evaluates the events that led her to meet Eric Cartman and what made her fall for him. She later recognizes the spot where she was kidnapped by the Halloween witch and where Cartman forced her to dress up as Gretel, realizing that Cartman tried to kill her. She then pulls a gun on Cartman, blaming him for the person she's become, but soon realizes she's been playing the victim since she's been with him. She decides to abandon the victim mentality and break up with him. Cartman tries to get Heidi back by threatening her, but the attempt fails, as Heidi is now fully aware of Cartman's manipulative nature and simply leaves him.

Baby Stevens:
Bebe seems to be very close to Heidi; they're possibly best friends. They're often seen chatting and having lunch together.

South Park Girls:
Heidi seems to get along well with all the members of the popular girls' group. She's often seen with one of them, either chatting in the background or playing in the yard, especially with Esther. She usually eats lunch with them. When she organized a sleepover at her house, she invited almost all the girls in her group.

In "The List", Heidi is a member of the "Plugs and Sparkles" girls' club.

Eric Cartman:
Cartman becomes annoyed with Heidi for not being submissive. He blames her for his unhappiness and accuses her of psychologically abusing him. Confused, Heidi cries, unable to understand Cartman's indifference. Cartman breaks up with Heidi, leaving her heartbroken. The next day, Cartman leaves Heidi a voicemail, threatening her if she doesn't get back together with him. Worried about him, Heidi agrees, and they resume their relationship. Cartman gets frustrated with Heidi for taking so long to get ready when they had planned to go to the pumpkin patch together. Instead of telling her how he feels, he tries to avoid expressing his feelings and, therefore, any guilt he would feel by telling her, irrationally trying to get rid of her. Kyle reprimands Cartman for this, telling him that "Heidi is a good girl," and that he should just break up with her instead of devising horrible plans to get rid of her, adding that she didn't deserve to be treated so badly. Cartman ignores her, and later convinces Heidi to dress up as Gretel while he dresses up as Hansel. Immediately afterward, he takes Heidi into the woods with him at night, eventually abandoning her there to die, and she is kidnapped by a witch. Heidi tolerates Cartman's mistreatment because she doesn't want to admit she was wrong to date him. These feelings are directly influenced by the other girls, who laugh at her and tease her for dating him, even if only jokingly. They also express concern for Heidi's mental health and safety during her relationship with Cartman, as they all resent her. Kyle addresses the issue and politely asks the girls to stop teasing her because it makes her feel unsafe. The girls assume Kyle has feelings for Heidi, which leads him to question his relationship with her, and he soon develops an interest in her. After breaking up with Cartman, the girls take Heidi to dinner at Buca De Faggoncini, where she is again berated.

Father:
When Cartman founded his church and parents were trying to convince their children to return, Heidi joined. Her father told her to come back, but then a beam from the poorly constructed roof of Cartman's church fell on him, killing him after she said she didn't want to go to hell. Although her father had died, he was later shown alive telling his wife that he was sorry for cheating on her with another woman.

Heidi is usually sweet and friendly, but sometimes unkind to the point of cruelty. She is a "popular girl" among the students and was seen participating in the girls' meeting, arguing about which girl's purse was the cutest. Heidi is always portrayed as an affable, considerate, cute, and sweet girl. She has been shown as one of the kindest and most socially sensitive girls in South Park. Heidi cares a lot about her appearance and, as a result, takes longer than usual to get ready for special events. According to Cartman, she has "no time management skills." A negative trait of her personality is her great pride. That's why she tolerates Cartman's bullying.
When she finally breaks up with him, her friends make fun of her for dating him.
Heidi reaches her breaking point and is ready to threaten Cartman, blaming him for her personality change. She soon realizes that Cartman wasn't the culprit, but rather her own victim mentality. She decides to abandon that mindset and regains her kind and caring personality.

Like her ex-boyfriend Cartman, Heidi has brown hair, only instead of light brown like Cartman, Heidi has light ash brown hair, medium length at shoulder height.
He wears a lime green jacket with a red collar, black pants, and red gloves.

Heidi is portrayed as one of the "popular girls." She is often seen with Wendy, Bebe, Red, Nichole, Annie, Nelly, Jenny, Lola, and many other girls. Despite being the only girl besides Wendy who wears a hat, her official hair color is ash brown. She has a slightly more feminine and childlike appearance than Karen McCormick, especially since acquiring the hat—a childlike style hat—as part of her basic look.
