Gran Rey Cero

is an Arrancar variation of the Cero technique. It is used by the Espada.

Description
A Cero which only Espada can use. It is performed by mixing an Espada's own blood with the Cero. The result is a Cero with much greater attack power and speed and a change of color unique to the Espada. It is many times more powerful than a normal Cero, capable of disturbing the fabric of space. Upon release, it seems to spin like a razor as it compresses and decompresses due to the sheer speed and raw power. Ulquiorra Cifer states using a Gran Rey Cero is one of two things forbidden while inside Las Noches, as it is so overwhelming it could destroy the fortress.
