Yammy

Yammy is the 10th Espada in Sōsuke Aizen's army. Yammy is a giant, dark-skinned arrancar. 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. 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 people with even slight spiritual power are able to resist it.

Yammy initially appears in Karakura Town along with Ulquiorra as the first team of arrancar to scout out the human world. Yammy injures Yasutora Sado and Orihime Inoue, but is stopped by Ichigo before he can kill them. Ichigo quickly slices off Yammy's arm, in revenge for injuring Sado. In the end, he is fended off by Kisuke Urahara and Yoruichi Shihouin, who make sport of him. Sometime after retreating to Hueco Mundo, an arrancar medic re-attaches his severed arm. To test the arm's strength, he strikes the medic's head and instantly kills her. The only regret he expresses after doing so is that she didn't split in half. He then returns to Karakura Town on a second assault, only to be toyed with by Kisuke Urahara again before having to retreat with the rest of his group.
