Monstrous alien being with leathery bat-like wings, its shaggy black torso contrasting against elongated limbs tipped with menacing claws, a grotesque visage featuring a predator’s maw filled with glistening, razor-like teeth emerging from the gloom of a mist-laden cavern, its chilling amber eyes glowing with menace, embodying the essence of cosmic horror, dark and intricately designed with extreme attention to detail, set in dramatic lighting, photorealistic and cinematic, with atmospheric grain, captured in ultra high definition.
