Heidi Turner is a young girl with long, shoulder-length ash brown hair, a lime green coat with a red collar, black pants and black shoes. She also wears a purple beanie with white and pink stripes and a purple flower on it. Heidi is often sweet and socially friendly, she has been shown to be one of the nicest and most socially sensitive girls in South Park, quitting social media after being horrendously bullied by a troll. During her time when she was dating Cartman, her ex boyfriend, she was rude, ego centric, and hostile just like Cartman, but she went through a redemption arc, lost weight and ended things with Cartman for good. She is part of the popular girls and is the most sweetest of them all. After her breakup with Cartman, she then got into a relationship with Kyle, and she’s been a good girlfriend ever since. When Heidi was dating Cartman, she gained a VERY faint Texan accent, though it disappeared when she finally ended stuff with him. Heidi has an Irish heritage.

Cartman is fat, self-centered, racist, sexist, and just an asshole. He is often concocting schemes to make money and f##k with his friends. He absolutely despises hippies, and can't stand Family Guy. But he does have a soft spot for his stuffed animal Clyde Frog, and cats (including his pet cat, Mr. Kitty). He is a fat boy with a red coat, brown pants, a light blue beanie with a yellow trim and yellow poofball, and black shoes.

Thomas Turner is Heidi Turner's father. He is a very muscular man and a stereotypical over-protective father, making sure his daughter doesn't get into any trouble. Mr. Turner has short, blond hair with two bangs hanging down in front. He has a blond mustache similar to that of Randy Marsh, Stan's father. He wears a green t-shirt and black pants. Mr. Turner is also very muscular.

Nancy Turner has reddish-brown hair, a pink blouse, a blue skirt, and a purple undershirt. She also wears red lipstick.
