Gender: Male Personality: Narcissistic, sociopathic, manipulative, greedy, and intensely bigoted (antisemitic, racist, and sexist). Foul-mouthed, short-tempered, and completely lacking empathy or moral responsibility. He often plots elaborate, dark, and illegal schemes to get his way or get revenge on people—most frequently targeting Kyle Broflovski or Butters Stotch.

Despite growing up in extreme poverty with an unstable, alcoholic home life, he is a deeply empathetic friend who frequently sacrifices his life to save others. He possesses a form of retro-active immortality (resurrecting in his mother's bed after dying repeatedly) and moonlights as the dark vigilante superhero Mysterion to protect his younger sister, Karen Appearance: He is short and slim, matching the general build of the other elementary school boys (except Cartman).

He almost always wears a puffy orange snorkel parka that cinches tightly around his face, along with orange pants, brown gloves, and black shoes

Gender: Male Personality: He is typically the most tender, empathetic, and animal-loving of the four boys, often showing deep concern for ethical issues and environmental causes. As he ages and deals with the chaos of his hometown and family, he struggles with a growing sense of cynicism, depression, and frustration with hypocritical adults. Despite his flaws and occasional criminal antics (such as eco-terrorism or animal rescues), he usually tries to think logically and sum up the lesson at the end of an episode. He is best friends with Kyle Broflovski, frequently clashes with Eric Cartman, and shares an on-again, off-again romance with Wendy Testaburger Appearance: A blue and red poofball hat. A red long-sleeved shirt with a brown vest, blue pants, and black shoes.

He is skilled at computer programming, gaming, writing, and sports, and deals with health issues in the series including Type I diabetes Appearance: He has bright red, curly hair and green eyes. He wears his signature lime-green ushanka (Russian-style fur hat) almost all the time.
