Ulquiorra Cifer, Five World War Wikia

Ulquiorra Cifer is the Cuatro (4th) Espada in Aizen's army of Arrancar. Ulquiorra is a very cold, callous, and dispassionate figure, and is rather aloof, brooding, and indifferent, willing to harm both his comrades and enemies should they get in his way. He refers to anyone he does not find interesting as "trash", and treats them as expendable. Despite this, like most of the other top Espada, he is not particularly violent, and will only fight when provoked or ordered to by Lord Aizen. As stated
