Ulquiorra 

Here to read what I'm typing? Today I'll be posting a wiki about Ulquiorra Cifer (Espada 4)

Ulquiorra is slender,messy hairy and white skin and has a upper black lip. His facial expression rarely changes, though he is almost always frowning, he wears typical arrancar clothes, like any other arrancars, His hollow hole is located in the Sternum. Though the hole was initially on the base of his throat. He's espada tattoo lies on the left of his chest. As a hollow, a full white mask and body. And a line running up the middle of he's eyes. He's horn reach up to he's hair and had a horn on the side of the mask. Ulquiorra is very cold, callous and is a dispassionate figure. Ulquiorra's past as a hollow Ulquiorra felt alone in the world, being white those around him were black. He wandered Hueco Mundo, lamenting he's existence, until one day he came across a white tree with many sharp spines. Ulquiorra finding it satisfying due to it's emptiness, sank into it, destroying parts of his mask, finally at peace. An unspecified amount of time later, Aizen recruiting him into the Espada.
