Cero Sincrético

is a variation of the Cero technique, used by Pesche Guatiche & Dondochakka Birstanne.

Description
Pesche and Dondochakka, charging their Cero simultaneously, combine them, forming a large, swirling sphere. They, firing the combined Cero, launch a multi-colored beam. Although it does not work on him, Szayelaporro Granz admits it is a "marvelous technique" and if they had used it before he had time to analyze their reiatsu, he would have been defeated. It seems to greatly drain Pesche and Dondochakka - both are panting and on the point of collapse after performing it.
