"In German-speaking Alpine folklore, Krampus is a horned, anthropomorphic figure who punishes children during the Christmas season who have misbehaved, in contrast with Saint Nicholas, who rewards well-behaved ones with gifts. Regions in the Austrian diaspora feature similar figures and, more widely, Krampus is one of a number of Companions of Saint Nicholas in regions of Europe. The origin of the figure is unclear; some folklorists and anthropologists have postulated a pre-Christian origin for the figure (see Germanic paganism).
Traditional parades in which young men dress as Krampus, such as the Krampuslauf (English: Krampus run), occur annually in most Alpine towns."
