Create a realistic full-body portrait of a male character with a supernatural theme. He has pale skin with a youthful, yet stoic expression. His hair is silver, slicked back to reveal two large, curved horns made of red ice protruding from his head. He wears a long, sleek, dark coat with hints of red, under which is a futuristic body armor that seems to integrate with his body, glowing with a soft red light. His eyes are piercing, with a red glow hinting at his otherworldly nature. In his right hand, he wields a trident with a handle that looks like twisted dark metal and prongs made of red ice. From his spine protrudes an organic-looking extension resembling a frozen spine, fading into a tail, both made of red ice. His overall stance is commanding, with a hint of elegance, as if he's a guardian of an ancient, mystical realm. The setting is a futuristic urban environment, with neon lights and a slight mist that reflects the city's glow.
