Chernabog is a fictional character who appears in the Night on Bald Mountain segment of Walt Disney's Fantasia (1940). He is a massive nocturnal demon who holds power over various restless souls. He is considered among the most visually impressive characters appearing in Disney's films along with the most malevolent of all Disney villains, and has made appearances in several Disney-related media. Despite that his segment of the movie didn't last very long, Chernabog was a horrifying character, especially among younger audiences. His name is taken from Chernobog, an evil deity of Slavic mythology; the name is Slavic for "black god." He is considered by many to be one of the greatest Disney villains of all time (an irony since his appearance is very brief).
