A painting of a demon with wings and a demon face

Create a nightmarish and terrifying portrayal of Agares, the enigmatic duke of the east. Show him as a decrepit, ancient figure with withered, skeletal features, mounted on a grotesque, mutated crocodile. His hawk should be a sinister, shadowy creature, its eyes glowing with malevolence. The atmosphere should be shrouded in darkness, with eerie, ghostly figures fleeing in panic from his presence. Agares should emanate an aura of dread, with his ability to cause earthquakes and command the forces of the underworld ominously evident.
