Cero Doble

is an Arrancar variation of the Cero technique. It is a signature technique of Nelliel Tu Odelschwanck.

Description
She retains her attack absorption ability in her original form, but now performs it with greater ease. According to Nnoitra, it is Nelliel's specialty. When executed, Nelliel absorbs an incoming Cero and fire one of her own while returning it, thus creating a potent Cero Doble. While her child form severely limits her Arrancar powers, she is still powerful enough to absorb and redirect a Cero blast from a Privaron Espada-class Arrancar in its released form, though the effort seems to tire her immediately. In her original form, the force of the Cero Doble is augmented greatly, owing to the fact that she rebounds the attack while blending it with her own Cero, drastically increasing its power, as befits the former third Espada.
