Chernabog is a demon featured in the "Night on Bald Mountain/Ave Maria" segment and the main antagonist of the 1940 Disney animated feature film, Fantasia. He is based on the God of the Night in Slavic mythology. At Walpurgis Night (the Witches' Sabbath), he emerges from the peak of Bald Mountain to summon all of his minions, who dance furiously as he throws them into the mountain's fiery pit. Described as “Satan” by host Deems Taylor, Chernabog has been praised as Disney's best representation of pure evil, and as animator Vladimir Tytla's greatest triumph. As a very "raw" representation of evil, he, in his original appearance, is not placed in the context of any real story. Furthermore, he and his minions' actions are not committed in pursuit of any discernible goal other than general tyranny. Some other media has attempted to give his character a more concrete context. Despite the tonal contrast between the character and other antagonists in the Disney pantheon, Chernabog is a primary member of the Disney Villains franchise, most heavily featuring as a centerpiece in merchandise and other experiences.
