The speed, power and blast radius of the Cero is entirely dependent on the user (commonly the stronger the user the stronger the Cero), and there are some Arrancar - and even Visoreds - who have invented their own variation of the attack.
 Cero DobleNeliel Tu Oderschvank. This variation requires the user to swallow an already oncoming Cero and firing it back after adding the users own Cero to it. However this move can be executed with such speed that it looks like the attack originally came from the foe. It was shown to be used against Espada Quinto Nnoitra Jiruga.
When in child form, Nel was shown to only able to fire the Cero back at the target, rather than adding her own Cero to it. She used this against the Cientecimo Tercero Privaron Espada Dordonii Alessandro Del Socacchio.
 Cero SincréticoDondochakka Bilstin and Pesche Guatiche. This was first seen during their fight with Espada Octava, Szayel Aporro Granz. Pesche and Dondochakka are shown to gather several Cero and focus it all into a swirling ball. Although having no effect on Szayel he notes it as a 'marvellous technique', and if they had used it at the start of the battle he would have been beaten by it (before he had no time to analyse their Riatsu). However the attack seems to seriously drain Pesche and Dondochakka as after using the move they are both panting heavily and exhausted to the point of collapse.

This is a variation performed by Charlotte Cuuhlhorne, fraccíon to Espada Segunda, Barragan Luisenbarn. Despite it's long name and shaped into a heart, it is just an ordinary Cero as noticed by Yumichika Ayasegawa. However it's blast radius is larger than that of a normal Cero.

 Cero Metralleta
Cero Metralleta (無限装弾虚閃 (セロ・メトラジェッタ), sero metorajetta; Spanish for "Sub-Machine Gun Zero", Japanese for "Infinite Ammunition Hollow Flash") is a variation of the Cero used by Coyote Starrk in his Resurrección state. With this right pistol he fires, in quick succession, a barrage of Cero at his target. This was seen in his fight with Shunsui Kyōraku.
Commonly the colouring of a Cero is a Crimson Red although high level Arrancar seem to be significant colour variations that differ from the norm. Fraccíon to Barragan Luisenbarn, Findor Carias is able to fire an indigo colour Cero from the top of his sword, Ichigo's Hollow Form can fire a Tri-Focused Crimson Cero although changes to a Violet/Purple in his second form and Mila-Rose's Cero is orange with a brown tint. Choe Neng Poww, Ulquiorra Cifer, and Lilynette Gingerback's are green, both Nnoitra Jiruga and Dondochakka Bilstin's are golden yellow, Ggio Vega's Cero is rose-colored, Nirgge Parduoc's is light teal, and Neliel Tu Oderschvank, Pesche Guatiche and Sun-Sun's seem to be Violet or Pink.
