Cero

Cero is a strong and swift spirit energy-based attack used by upper-level Hollows, Arrancars, and Vizards.

Description
is a form of attack used by Menos, Arrancar and Vizard. It consists of firing a blast of concentrated spirit energy at the target. While in most cases it is fired from the mouth, some Arrancar and Vizard are capable of firing Cero from their hands, fingers and other parts of their bodies.

The power, force, speed, color, and blast area of the cero is dependant on the strength of the user (i. e. the stronger the user the stronger the attack), and there are some Arrancar and Vizard who have come up with their own variation.

Cero Doble
is a variation performed by Neliel Tu Oderschvank, by swallowing her opponent's Cero and returning it back to the user along with her own cero. This attack was seen used against Nnoitra Jiruga. .

While in her child form, Nel is only able to return the Cero fired by her opponent as seen used against Dordonii Alessandro Del Socacchio.

Cero Sincrético
is a variation performed by Dondochakka Bilstin and Pesche Guatiche. This attack was first seen being used against Szayel Aporro Granz.

This variation is performed by Charlotte Cuuhlhourne. Despite having a very long name and the shape of a heart, it is just an ordinary Cero as noted by Yumichika Ayasegawa.



Gran Rey Cero
is an Espada-exclusive Cero. It is performed by mixing an Arrancar's own blood with the Cero. The result is a Cero with a much greater attack power and speed as well as a change of color unique to the Espada. This attack was first used by Grimmjow Jeagerjaques in order to incite Ichigo Kurosaki into donning his mask. It is stated by Ulquiorra that using a Gran Rey Cero is one of two things that are forbidden while in Las Noches, the other being an Espada above cuatro releasing their zanpakuto, as these are so powerful they would destroy Las Noches. So far, Grimmjow Jeagerjaques is the only member of the current Espada to utilize this attack.

Cero Oscuro
is a black Cero, used only by an Espada in their released form. So far, Ulquiorra Schiffer is the only arrancar to utilize this attack. He compares it to Ichigo's black Getsuga Tenshō. It covers any exposed light into pitch darkness. Though the only Espada shown to utilize this technique so far, Ulquiorra told Ichigo "This is an Espada's fully powered Black Cero." This likely means that, similar to Gran Ray Cero, Cero Oscuro is an Espada specific attack. However it is too early to tell for sure, because only Gran Rey Cero coupled with any Espada above Cuatro releasing their power are forbidden under Las Noches. Obviously Cero Oscuro should be forbidden as well, since an Espada ranked below 4th (perhaps Nnoitra) should be able to use Cero Oscuras after his/her ressureccion under Las Noches. Ulquiorra also referred to it as "my cero." The Cero Oscuro's range is vast, and its attack power is unknown, though it is powerful enough to shatter Ichigo Kurosaki's Hollow mask, critically injuring him in the process, and strong enough to destroy 1/3 of the dome over Las Noches. The superior Cero Oscuro is far greater than a average Cero. There is also the Instantaneous Cero Oscuro.

Others
While most Cero are red or crimson, Ichigo's Hollow form's Cero is tri-focused and crimson, but possibly also come with a pink color. Some Espada appear to have great color variations in their Cero. Ulquiorra Schiffer's is green, Nnoitra Jiruga's is golden yellow, and Neliel Tu Oderschvank's seems to be violet or pink (as she was using Cero Double; it is unclear if her normal Cero is a different color). Due to the color differances seen in the Cero of different Arrancar, it can be assumed that it is only in Hueco Mundo that the Cero have different colors, as seen with Grimmjow Jeagerjaques, as when he used it in the normal world it was red, but in Hueco Mundo, it was blue. It can possibly be seen with Yammy as well, as all the other Espada has shown color variations, and as his was red in the normal world, it is possibly colored in Hueco Mundo.
