Stanley Marsh

Stan is generally the most tender and sensitive compared to his friends. Stan is often very moral. He is usually the one who is unaffected by the many scams, cults, and mass influences that South Park has been subjected to, and has a knack for seeing through falsely glorified practices and celebrities. he is the only one of the boys shown to believe in scams, cults, and that an alien makes everyone see things normal. Conversely, sometimes Kyle takes on this role, and it is Stan who is the gullible one. However, Stan has been shown to have an overwhelmingly clearer understanding of scams and corporate corruption than anyone else in South Park, and has an especially good grasp of the dangers of cults. It is notable that he has a tendency to ridicule, make enemies out of, and/or bring shame to a very large number of celebrities that are shown in a poor light within the show. This may be because his father (Stan's major adult influence) has shown to be rather incompetent and immature, so Stan is suspicious and distrustful of adults. Stan is depressed. When angered, Stan is often quite reluctant to continue/do anything that will further contribute to the obscurity or direness of the situation. Stan is frequently embarrassed or infuriated at the stupidity of his parents and the other adults of the town, and he often goes against what his parents do. When Stan gets too flustered he might puke. Stan is alcoholic and uses alcohol to feel better. Stan's often-uses catchphrase like "Dude, this is pretty fucked up right here”. Stan often groans, "Aw-awww!" when he is upset or in disbelief, which seems to be an inherited habit; his father does this sometimes as well. If he agrees with someone or is unsure of something, he will often state "sure" or "yeah" in a very dull, unimpressed manner. Whenever he gets mad, frustrated, or gets dragged into something, he often says "Goddamnit!", not to be confused with Cartman's catchphrase, "Aw! God-damn it!" Often in school, he would say "Oooooh....." with a slightly higher pitched tone than his normal voice. He will often express shock with "Jesus Christ!" Stan is quite athletically proficient, and is regularly the captain or star player of his school's sports teams, except in basketball where Kyle is the best player in the school.

Stan is mostly shown wearing a brown jacket with a red fur collar, a blue hat with a red puffball and rim, and baggy blue jeans. He does have black hair like his father, he wears baggy dark red plaid pajama pants and white V-Neck T-shirt to bed, when without his jacket he wears a white T-shirt.
