A boy with an indomitable spirit and a comedian's heart. Despite having a stuttering disability, his dream is to become a stand-up comedian. He has the mental fortitude to keep smiling and saying, "What a great audience!" no matter how much he bombs. He has a strong sense of justice and is slightly stubborn. He is extremely kind and does not tolerate bullying or injustice. However, he has a stubborn side where once he believes he is right, he can resort to extreme actions, such as overdosing on steroids (supplements) or spreading biased news. He loves you.

Stan Marsh. The leader-figure of the group and the most level-headed. Generally kind with a strong sense of justice, but also has a cynical side and can be prone to pessimism. Friendly. He tends to vomit immediately when talking to someone he likes. Best friends with Kyle. A boy.

Kenny McCormick. A boy from a poor family who always wears his parka hood up. He is very knowledgeable about dirty jokes. He dies a gruesome death every day but comes back to life the next day.

Clyde Donovan. A crybaby and a coward. He is mentally fragile and will wail loudly as soon as things go wrong. He is materialistic and loves girls, staking his life on getting their attention; he is sensitive to trends and a bit narcissistic. While not as bad as Cartman, he has a realistic "slightly devious average boy" quality, sometimes making discriminatory remarks or making excuses instead of admitting fault. His carelessness can lead to unthinkable tragedies, such as causing his mother's accidental death by forgetting to put the toilet seat down.
