Dokkaebi (Korean: 도깨비) is a mythical being in Korean folklore or fairy tales. Although usually frightening, it could also represent a humorous, grotesque-looking ogre or goblin. These creatures love mischief and playing mean tricks on bad people. They also reward good people with wealth and blessings. They are different from Gwisin (Korean: 귀신; Ghost) in that they are not formed by the death of a human being, but rather by the transformation of an inanimate object.
