Mr. Hankey is a minor character in South Park: The Stick of Truth, South Park: The Fractured But Whole and South Park: Phone Destroyer. In South Park: The Stick of Truth, he is a summon upon completing his quest.
Mr. Hankey is a piece of feces with three lumps and wears a Santa hat and white mittens. When summoned into battle, he replaces his Santa hat with a wizard hat and puts on a red wizard robe with a golden belt (similar to Mickey Mouse's outfit from Disney's Fantasia).
In South Park: Phone Destroyer, his appearance is the same, but with rosy red cheeks.
