Chernabog is the main character of the "Night on Bald Mountain" segment of the film Fantasia.
In Epic Mickey[]
Notice: This article or section contains information about content that was planned or conceptualized for the Epic Mickey series, but was ultimately scrapped. Information about scrapped content should not be considered canon.
While he doesn't appear directly in Epic Mickey, there is a painting of him in the foyer of Lonesome Manor hiding Gremlin Haig and the "Lonesome Manor I" Extra Content.
In concept art, he's a Mickeyjunk Mountain's guardian.
Chernabog was, however, originally in the game before getting scrapped. He was to appear as the guardian of Mickeyjunk Mountain, and it is unknown if he would have been an ally or an enemy.
Epic Mickey: Tales of Wasteland[]
The actual character does make a cameo appearance in the Epic Mickey digicomic, "Oswald the Lucky Duck". Oswald's third attempt to remake himself with the Mad Doctor's Projectorinator turns him into a rabbit/devil combination and, as Oswald soon finds out, sets him on Bald Mountain with the baddie himself. As Oswald is rooted in one place (like Chernabog is), he can't escape as a big, black claw reaches down toward him. Fortunately, due to Chernabog summoning fire, the Projectorinator catches fire and explodes, freeing Oswald from the demon.
In Epic Mickey 2: The Power of Two[]
Chernabog appears in The Power of Two as his segment is one of the projector screens that connects to Rainbow Falls to Disney Gulch. Here, he can be seen in the background. Later, a second segment connects the Mad Doctor's Attic to the Mad Doctor's attraction. This one goes up Bald Mountain itself, so Chernabog can be better seen at the end.
