A demonic creature with horns and a red face stands in the middle of a mountain

a full-body portrait of Satan, with intense fiery eyes and a sinister grin, surrounded by a hellish landscape. The devil is depicted with intricate horn structures, sharp fangs, and a muscular physique. His skin is dark red and covered in intricate tattoos, symbolizing evil and darkness. He is dressed in a flowing black cloak, which billows dramatically in the fiery winds of the underworld. The background is filled with volcanic landscapes, molten lava, and ominous dark clouds. The entire scene is bathed in an eerie red and orange color palette, giving it a hellish and sinister atmosphere. The lighting is dramatic, with deep shadows and intense highlights emphasizing the devil's features. The overall image quality should be of the highest caliber, with ultra-detailed textures and realistic rendering. The style should be a dark and menacing portrayal of Satan, reminiscent of horror and fantasy art.
