Cero Doble

is a variation of the Cero technique used by Nelliel Tu Odelschwanck.

Description
After absorbing an incoming Cero by swallowing it, Nelliel fires one of her own while returning the previous one, 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 his released form, though the effort greatly tires her. In her original form, the force of the Cero Doble is augmented greatly, since Nelliel rebounds the attack while blending it with her own Cero, which drastically increases its power.
