Yammy

Yammy is a giant, dark-skinned arrancar, with a distinct ridged cranium and a black pony-tail. What remains of his hollow mask is the jawbone, which rests on his chin. A tattoo of the number ten, signifying Yammy's rank and level of power amongst the Espada, is on his left shoulder. Not the most intelligent individual, he relies on his brute strength in battle, taking little interest in using his sword until he is overpowered. In addition to his strength, he makes use of cero and bala blasts, like many other high-class hollows and arrancar. He relies on his superior, Ulquiorra Schiffer, to explain things and give him orders while in battle. Aside from his fighting abilities, Yammy can suck the souls from living humans en masse using gonzui. It affects a wide area, but any individual with even slight spiritual power are able to resist it. Despite being one of the first arrancar and espada seen in the series his zanpakuto's name and full powers have yet to be seen.
