Chernabog

Chernabog is an immense demon who serves as the main antagonist of the final segment of Fantasia, "Night on Bald Mountain", though he is often considered the antagonist of the entire film. In "Night on Bald Mountain", Chernabog emerges from Bald Mountain and beckons his minions, who he casts into a fiery pit.

Fantasia
Chernabog emerges from Bald Mountain overlooking a village. Summoning the dead, including those of executed prisoners, deceased warriors, and those not buried in sacred ground. As they swirl around Chernabig, he summons demons and fire, who gather below him. Chernabog proceeds to toss them into the firery pit of Bald Mountain. He then conjures images from the flames, first of dancers, then barnyard animals, who he converts into demons. Summoned harpies fly above the demons and intermittently fling them into the inferno. However, the chaos is brought to an end by the sun rising, heralding the coming of dawn. Chernabig's minions retreat and the ghosts return to their resting places, while Chernabog hides from the sun and becomes the peak of Bald Mountain once more.
