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 South Park: The Fractured But Whole, his jolly suit is tattered after falling off the sky from The New Kid's prayer. He will be seen handling a baseball bat.
In South Park: The Stick of Truth, 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.
In South Park: The Fractured But Whole, Santa is only seen in the mission Farts of Future Past, where he will appear after being summoned through The New Kid's prayer. He assists The New Kid in battling the Woodland Critters on Main Street. After helping to defeat the Woodland Critters, Santa then offers his help to deal with the chaos happening in South Park.
