A Black Demon as seen in the Rankin-Bass version of The Life and Adventures of Santa Claus.
The Black Demons of Patalonia are evil creatures with great spreading wings, like a bat. They sweep terror and misery through the world as they beat upon the air.
These Black Demons joined the Awgwas in an epic battle against Ak the Master Woodsman and his army of immortals. It was never stated who vanquished the Black Demons. The forces of good were able to defeat the evil races, destroying most of them. (The Life and Adventures of Santa Claus)
