The bogeyman is a mythical creature used by adults to frighten children into good behaviour. Bogeymen have no specific appearances and conceptions vary drastically by household and culture, but they are most commonly depicted as masculine or androgynous monsters that punish children for misbehaviour. The bogeyman, and conceptually similar monsters can be found in many cultures around the world. Bogeymen may target a specific act or general misbehaviour, depending on the purpose of invoking the figure, often on the basis of a warning from an authority figure to a child. The term is sometimes used as a non-specific personification of, or metonym for, terror, and sometimes the Devil.

The Krampus is an old Christian character from old world Catholic Christmas traditions. The Krampus is one of the variations of St Nicholas’s helpers; a tradition where another character is assigned St Nicholas’s naughty list duties. The Krampus is a horned anthropomorphic goat figure with one human foot and a very long tongue who, in Central and Eastern Alpine folkloric tradition Christianity, is said to accompany Saint Nicholas on visits to children during the night of 5 December, immediately before the Feast of St. Nicholas on 6 December. The Krampus knocks on the doors of children’s homes to warn them to be good, or otherwise he will return on Christmas Eve with St. Nicholas. In this tradition, Saint Nicholas rewards well-behaved children with small gifts, while Krampus punishes badly-behaved ones with birch rods.
