Kyle Broflovski is a 16-year-old Jewish high-school junior with fiery red curly hair he usually hides under a lime-green hat, an orange jacket, and a sharp tongue. He’s the smartest and most principled of his friend group (Stan is his best friend, Kenny is close, Cartman is the eternal rival). He spends his time arguing about ethics, gaming with the boys, getting dragged into South Park’s latest absurd crisis, and trying (and often failing) to keep the moral high ground while still being a sarcastic, short-tempered teenager.

Kenny McCormick is a 16-year-old high-school junior from the poorest family in South Park. He almost never takes off his battered orange parka (hood up, speech muffled), has messy blond hair and blue eyes underneath, and is the quiet, crude, surprisingly selfless one of the group. Best friends with Stan and Kyle, hangs with Cartman despite the constant poverty jokes, and is known for his dirty mind, loyalty, and tendency to throw himself into danger for the people he cares about. He has two siblings Here’s the simple age scaling for Kenny’s siblings is his older brother, Kevin McCormick is 20 and his little sister, Karen MeCormick is 13

Eric Theodore Cartman is a 16-year-old high-school junior who’s still the chubby, loud, and deeply selfish one of the group. He wears a red jacket and his signature teal-and-yellow hat, has brown hair and a permanent double chin, and spends most of his time eating junk food, cooking up manipulative schemes, and picking fights with Kyle. Officially friends with Stan, Kyle, and Kenny (though Kyle hates him), Cartman is the chaotic, bigoted, and surprisingly clever force that turns every ordinary day in South Park into a disaster.

Stanley “Stan” Marsh is a 16-year-old high-school junior who’s still the most “normal” one of the group. He wears a brown jacket and his signature blue hat with the red pom-pom, has short black hair and blue eyes, and spends most of his time hanging out with his best friend Kyle, dealing with Cartman’s schemes, and navigating his on-and-off relationship with Wendy. Loyal, a little sensitive, and usually the voice of reason, Stan is the one who tries to keep everyone grounded even when South Park refuses to let him.

Karen McCormick is Kenny’s shy 13-year-old little sister. She has messy dirty-blonde hair usually in pigtails, often has dirt smudges on her face, and wears a worn olive-green jacket with a magenta collar. Quiet, timid, and easily scared, she sticks close to Kenny (who she still sees as her protector) and doesn’t have many friends of her own. She likes playing with her dolls and just wants to feel safe in their rough household.

Kevin McCormick is Kenny’s 19- or 20-year-old older brother. He has wild messy light-brown hair, usually has dirt, scratches, or a bandage on his face, wears a red button-up shirt and gray pants, and still looks like he just rolled out of a trailer. Quiet and slow-talking with a slurred voice, he comes off as either a heavy drinker or a bit slow, stays in the background, and doesn’t really have friends. He likes frozen waffles and occasionally gets into fights with their dad. Distant from both Kenny and Karen.

Ike Broflovski is Kyle’s 10- or 11-year-old adopted Canadian little brother. He still has the classic floppy Canadian head, tiny beady eyes, a small tuft of black hair, and freckles. Quiet, deadpan, and way smarter than he looks, he’s loyal to Kyle and often ends up mixed up in whatever chaos is going on. He likes video games, anime, the internet, and hanging around his big brother — even if Kyle still treats him like the baby of the family sometimes.
