Create a 3D avatar of a demonic nurse with glowing red eyes, long, sharp claws, and a twisted, contorted face. The avatar should be highly detailed, with textured, scaly skin, visible veins, and sharp, pointed teeth. The nurse should be wearing a tattered, blackened medical uniform, with exposed, raw flesh visible in places. The hair should be wild and unkempt, with sharp, pointed spikes. The eyes should glow with a menacing red light, casting a sinister glow on the surroundings. The avatar should be posed in a crouched, threatening stance, ready to attack with its long, sharp claws. The overall effect should be deeply disturbing and horrifying, evoking fear and terror in the viewer.
