Eric Cartman is "the fat one". He is made fun of numerous "fat" jokes, but he insists that he is just big boned. He has a pig named fluffy, loves cheezy poofs and was given an anal probe by alien visitors. Cartman's mom is on the cover of the crack whore magazine and he always tries to deny it. His mom is also his dad.
Stan is known as 'The Puker' because he pukes whenever Wendy Testaburger his biggest crush talk to him. However, they become South Park's sweetest couple. Also don't forget that Stan always points out the fact that someone has killed Kenny by saying, 'They killed Kenny. Oh yeah, he also has a gay homosexual dog called Sparky, and he is the quarterback of the South Park school football team. Stan also gets beaten up a lot by his sister, shelley. He also has a weird grandpa who wants Stan to kill him all the time.
Kyle is jewish. His mom caused the T.V. show Terance and Phillip to be taken off the air. has a little brother named Ike and he like's to kick him like a football. Also he follows Stan's 'They killed Kenny' by 'You bastards'.
Kenny is my personal favorite. Kenny dies in every single episode. Believe me, although Kenny's small, he makes the most perverted comments. Kenny's family is very poor and this is also pointed out throughout all the episodes... poor Kenny. His dad is an alcoholic, and his mom is no better. But Kenny's still the coolest and the cutest. People do have problems trying to understand what he says in every single episode, but it seems quite difficult. South park would never be the same without him.
Ever seen Kenny without his red hood?
