Stan Marsh is a main character in the animated series South Park, voiced by co-creator Trey Parker, and is often seen as the most "normal" or "everyman" of the four central boys, alongside Kyle, Cartman, and Kenny. He is known for being sensitive, moral, and often the voice of reason, though he gets into many outrageous situations, frequently expressing frustration with "Goddamnit!". His character is loosely based on Parker and he often serves as the show's main protagonist.
