The Sixth Espada, death's aspect of Destruction: a blue-haired panther Arrancar thirsting for fights. Ichigo is the only opponent he has ever truly cared about.

He attacks Karakura twice on his own initiative, loses an arm as punishment from Tōsen, has Orihime restore it and immediately kills the Arrancar who had taken his place. In Las Noches he forces Orihime to heal Ichigo so he can beat him at full strength, and loses. Having survived, he reappears in the final battle against the Wandenreich, fighting once more — in his own way — alongside Ichigo.
