Ulquiorra is a male arrancar with a melancholic appearance and has green eyes with slit pupils. He has cyan lines descending from his eyes, making it appear as if he is crying, and is almost always frowning. He wears typical arrancar clothes: a white jacket, black sash, and a white hakama. They are somewhat similar to what Ichigo's inner hollow wears. However, his jacket seems to have longer coat-tails than others. Like most other arrancar, he possesses remnants of his former life as a hollow in his appearance. His hollow hole has moved; it is at the base of his throat as opposed to his chest. The remainder of his hollow mask lies on top of his head, forming a broken helmet, much like that of the example silhouette of a vasto lorde. His Espada number, four, signifying his rank amongst the Espada and level of power, is tattooed on the left side of his chest.
