A nightmarish alien entity with enormous bat-like wings and a coarse, black furred torso emerges from a thick, ominous fog shrouding an ancient, shadowy cave. Its elongated limbs end in vicious, razor-sharp claws, while its grotesque face is dominated by a gaping predator mouth lined with serrated teeth, ready to devour. Its fiery, malevolent orange eyes glint with peril in the dim light. This horror-laden creature is rendered with a dark, intricate design and striking details, set amidst dramatic, cinematic lighting that casts eerie shadows. The image captures a photorealistic, cinematic atmosphere with subtle cinematic noise, 8k resolution, and an imposing vertical aspect ratio of 9:16, conveying a sense of looming menace.
