Cast of South Park

Trey Parker provides the voice for Eric Cartman, one of the main characters and often the primary antagonist of the show. Cartman is a manipulative and morally ambiguous boy with a distinctive high-pitched voice and a penchant for outrageous schemes and offensive remarks.

Matt Stone lends his voice to two main characters on South Park - Kyle Broflovski and Kenny McCormick. Kyle is one of the more rational and morally conscious boys in the group, often serving as the voice of reason. Kenny, on the other hand, is known for his muffler-covered voice, along with a consistent habit of dying and being resurrected in each episode.

Isaac Hayes provides the voice for the character known as Chef. Chef, whose full name is Jerome Chef McElroy, is the school's cafeteria worker and a mentor figure to the boys. He is known for his smooth-speaking manner and his songs with explicit lyrics which often satirize current events.

Mary Kay Bergman was the original voice actress for Ms. Cartman, the mother of Eric Cartman. Ms. Cartman is an overprotective and doting mother who often spoils her son and turns a blind eye to his misbehavior. Unfortunately, Mary Kay Bergman tragically passed away in 1999.

Mona Marshall took over the role of Sheila Broflovski, Kyle's mother, following the passing of Mary Kay Bergman. Sheila is a well-meaning but often obsessive and hyper-involved mother, who frequently gets involved in school and community affairs.

Eliza Schneider voiced the character of Ms. Cartman after Mary Kay Bergman. Ms. Cartman, as described earlier, is the mother of Eric Cartman and exhibits a similar level of doting and indulgence towards her son.

Sebastian Yu lends his voice to Ike Broflovski, Kyle's adopted baby brother. Ike is depicted as highly intelligent for his age and often engages in humorous and precocious behavior.
