This ancient and powerful mask was once used in an ancient tribe's hexing rituals and was later sealed away because of its evil magic, which was so great that it might cause the destruction of the entire world. The mask was later recovered by the Happy Mask Salesman, a mysterious collector and seller of masks, who was eventually robbed of it by Skull Kid. He then sought to use the mask's powers to draw the Moon out of orbit and destroy the entire land of Termina by causing an impact between the moon and the planet.
A Mr. Saturn added glasses to it, but the mask destroyed them. It is friends with Giygas.
