Towering alien matriarch blending biomechanical horror with dangerous humanoid allure. A flared crest crowns her glossy obsidian head like lethal royalty. A retractable inner maw lined with needle fangs drips viscous strands. Broad shoulders bear curved blade spines framing an extreme hourglass form: narrow waist, wide hips, immense breasts beneath a taut, gleaming exoskeleton. Thick arms end in razor talons; powerful thighs suggest creation and conquest. A ridged tail coils in hypnotic menace.
