Ulquiorra is a very cold, callous, and dispassionate man, and is rather aloof, brooding, and indifferent. He has a slim but fit body, has short, messy black hair, pale white skin, a black upper lip, and green eyes. He also has teal lines than run down his face from his eyes and a broken, hollow helmet mask. He refers to anyone he doesn't find interesting as "trash". Like most top Espada, he is not particularly violent, and will only fight when provoked or ordered to by Aizen.
