Picture a sleek, towering alien with a sinuous, dark exoskeleton that shifts colors subtly in the light. Its head is a smooth, elongated dome with a retractable, petal-like faceplate, revealing a multitude of serrated teeth when open. The alien's eyes are gleaming, multifaceted orbs that shift in hue. It has long, spindly limbs with clawed fingers and toes, and its body is covered in a fire-resistant, chitinous armor. The design merges the predatory elegance of a Xenomorph with the nightmarish, otherworldly features of a Demogorgon, resulting in a creature that is both menacing and enigmatic.
