Create an ultra-realistic 3D avatar of a twisted, corrupted black female elf, with dark, malevolent features, twisted, deformed ears, and glowing, malevolent eyes. The avatar should be highly detailed, with a haggard, emaciated form, and a sickly, corrupted presence. The elf's skin should be mottled, with an unhealthy, pallid quality, and a range of sickly greens and purples. The hair should be thin and stringy, with an oily, greasy texture. The eyes should be small and malevolent, with a deep, unsettling glow that evokes fear and revulsion. The avatar should be posed in a twisted, contorted stance, with a sense of malice and aggression. The overall effect should be deeply disturbing and horrifying, evoking feelings of fear and dread in the viewer.
