Santa Claus is a minor character in South Park: The Stick of Truth. He is a world renowned holiday symbol.
Santa is a round and jolly old man with a white beard. He wears a red hat and coat and a black belt and boots. In fractured but whole, his jolly suit is scrapped thanks that he fell off the sky. He also handles a baseball bat.
Santa has no role in the story, but does appear on top of the roof of the police station. When the New Kid goes out the emergency exit of the police station, he uses his alien probe to get to the top to find Santa with a laptop. He then will become friends with the New Kid on Facebook after he talks to him.
