This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Dokkaebi (Korean)
Dokkaebi are legendary creatures from Korean mythology and folklore. Dokkaebi, also known as "Korean goblins", are nature deities or spirits possessing extraordinary powers and abilities that are used to interact with humans, at times playing tricks on them and at times helping them. Legends describe different dokkaebi in many forms and beings with a thousand faces, and dokkaebi often wear hanbok.
Dokkaebi are featured in many folk tale anthologies compiled during the Joseon period. Dokkaebi are different from ghosts, called gwishin, in that they are not formed by the death of a human being, but rather by the possession of an inanimate object such as old discarded household tools like brooms, or objects stained with human blood.
