A medium shot captures an imposing, mature male villain in his late thirties, standing in a menacing posture. He possesses a thin, pale, and weathered human face partially obscured by a terrifying, sleek, and sharp-edged mask that covers his nose and mouth, revealing only piercing, cold eyes. His attire consists of a dark, high-collared Victorian-inspired coat, from which multiple long, semi-translucent crimson tentacles emerge from his back, coiling around him like serpents. One tentacle extends forward, its tip sharpened like a needle, poised as if to extract essence from a target. He has smooth, slightly glossy skin tones, contrasting with the vibrant, dark blood-red hues of his tentacle appendages. The setting is a dimly lit, ominous gothic corridor with stone pillars and floating droplets of liquid blood glowing faintly in the air. The image features exceptionally clean linework and a gentle color palette, balancing dark shadows with soft highlights on his skin and the wet, pulsating texture of the tentacles, creating a sophisticated yet terrifying atmosphere.
