"Create a hyper-realistic image of a terrifying monster against a black background. The creature is half-octopus, half-ghostly human silhouette, blending eerie humanoid features with the twisted, tentacled form of an octopus. The upper part has the faint outline of a dark, phantom-like human figure, while the lower part transforms into multiple writhing tentacles. Each tentacle is lined with sharp, menacing teeth, adding to its nightmarish appearance. One tentacle is lunging forward as if attacking the viewer, its teeth glistening ominously. Shadowy wisps emanate from the figure, giving it a haunting, ethereal aura against the black background."
