"A powerful being with a humanoid upper body and a horse-like lower body

"A powerful being with a humanoid upper body and a horse-like lower body, embodying the essence of Vortex. The upper half of the creature is a muscular human figure with long black hair, dark eyes glowing with a crimson hue, and a single horn protruding from the forehead. The lower half transitions into a sleek, horse-like form with dark, metallic armor, and a prominent black and purple color scheme. The armor has intricate designs and dark energy emanates from it. The background is a stormy sky with dramatic lightning illuminating the scene, casting an eerie glow over the creature's form and emphasizing its formidable presence. The overall atmosphere conveys a sense of dark magic and primal power."
