Ulquiorra Cifer

a slender and rather muscular guy of average height and melancholic appearance. He has unkempt, medium-length black hair, pale white skin, a black upper lip, very bushy eyebrows, and green eyes with a slit pupil like a cat's. Part of his bangs falls between his eyes
Ulquiorra is very cold, soulless, emotionless, or even standing on the sidelines, brooding and indifferent, willing to harm both enemies and comrades to achieve his goal. He calls those who are not interesting to him trash, and views them only as consumables. Strict, insightful, cunning and judicious
