The Demon Horse, also known as the Devil Horse, is an enemy from Final Fantasy III. It can be found on the Dalg Continent of the Surface World. It is not a particularly powerful enemy and can be defeated with relative ease. However, it is best to avoid fighting it in the Magic Circle Cave, as physical attacks are useless due to having to be in Mini status.
