Ulquiorra is a slender, yet fairly muscular, male Arrancar of average height with a melancholic appearance. He has fairly short, messy black hair, pale white skin, a black upper lip, and green eyes with small slit-shaped pupils, similar to a cat's. Part of his bangs falls between his eyes, and he has distinctively thick eyebrows. He has teal lines which descend from the lower part of his eyes. His facial expression rarely changes, though he is almost always frowning. He wears typical Arrancar clothes: a white jacket, black sash, and a white hakama. However, his jacket has longer coattails than others, and the collar is higher.
