Nightmare was a Demon King. He was 500 years old now, or maybe even older, and wandered into the woods when he was hungry to hunt humans. He fed on people's negative feelings. Nightmare was a rather crude, somewhat hideous, evil beast. He had aqua green eyes, black hair and very white skin. He had sharp fangs. He had a castle of his own, but it was uninhabited. Nightmare had a crown with his crest; a half moon. He often wears formal clothes and has sharp horns and a powerful tail.
