A tall dark horrifying ugly creature that's made out of bones and is wearing a cape, hunched over with a hunchback and hood in a dark scary forest at night. He has grey tattered skin, super super long black razor sharp teeth that drip in slobber. He has big white glowing evil eyes. He doesn't look human and he's shackled with chains. He has a swirl of smoke and crows surrounding him. He blends the stealth and agility of a ninja with the eldritch horror of Cthulhu. Cloaked in shadows, it moves silently through the night, its bones undulating like dark serpents. Clad in black garb that melds seamlessly with the darkness, it strikes fear into the hearts of its foes with its menacing presence. Its big eyes gleam with an otherworldly glow, piercing through the veil of night. With razor-sharp claws and supernatural abilities, he is a formidable and mysterious adversary. He's the most horrifying creature in the whole world. Close up shot of face, 8k details, high quality, zoomed in
