Krampus, in central European popular legend, a half-goat, half-demon monster that punishes misbehaving children at Christmastime. He is the devilish companion of St. Nicholas. Krampus is believed to have originated in Germany, and his name derives from the German word Krampen, which means “claw.” According to legend, he is the son of Hel, the Norse god of the underworld. With the spread of Christianity, Krampus became associated with Christmas—despite efforts by the Catholic church to ban him. The creature and St. Nicholas are said to arrive on the evening of December 5 (Krampusnacht; “Krampus Night”). While St. Nicholas rewards nice children by leaving presents, Krampus beats those who are naughty with branches and sticks. In some cases, he is said to eat them or take them to hell. On December 6, St. Nicholas Day, children awaken to find their gifts or nurse their injuries.
