In Pop Culture
Chernobog has made appearances in various media. As Chernabog, he features in the "Night on Bald Mountain" sequence in Disney's Fantasia (1940), as a gigantic black demon who summons ghosts and demons. In an interview, Walt Disney referred to him as Satan himself. This rendition also appears in the video games Kingdom Hearts and Kingdom Hearts Dream Drop Distance, in both, as a boss character.
In literature, he appears in American Gods by Neil Gaiman, as "Czernobog." In the alternate history novel The Peshawar Lancers, the Russian Empire turns to Chernobog worship after a comet impact causes widespread famine and cannibalism. Chernobog is also the main antagonist in the Heirs of Alexandria series by Mercedes Lackey, Eric Flint, and Dave Freer. A version of Chernobog is also used in Richard Kadrey's third novel in the Sandman Slim trilogy, although it is spelled as "Chernovog."
He also appears in a number of video games, usually as a villain. In the Blood series (where the name is spelled as "Tchernobog") he is depicted not as a person but as an essence of a force that keeps the realities together and must be used by persons incarnating the god. The first game features an incarnation as the main villain, and the second game's plot revolves around the main character Caleb actually being the god. He has also appeared as a recurring demon in the Megami Tensei series.
Chernobog inspired the character of Avoozl the Dark One, the dark master of the penultimate antagonists Katrina and Ad-Avis in the Sierra Entertainment adventure-rpg Quest for Glory IV: Shadows of Darkness in which he is worshipped by a cult of horrendously mutated priests called "The Chernovy"
