Resurrección

Arrancar possess zanpakutō and can perform a technique similar to a Shinigami's release called. Unlike a Shinigami's zanpakutō, however, an Arrancar's zanpakutō is simply the Arrancar's Hollow powers sealed into the shape of a weapon. By releasing their zanpakutō in the same manner as a Shinigami, an Arrancar can release his or her Hollow powers. Most known Resurrección give the Arrancar user an animal-like appearance. While most unreleased Shinigami zanpakutō take the form of a katana or wakizashi, there is a significantly broader range for Arrancar (such as a sai, axe, or a more fictionalized weapon like Nnoitra's zanpakutō).

Because their powers are sealed in their zanpakutō, an Arrancar's release will usually transform their body into a Hollow-like form, allowing them to use their abilities freely. This form usually reflects what the Arrancar looked like as a Hollow, although to highly varying degrees. A Resurrección restores an Arrancar to its "true" form, resulting in significantly various increases in speed, strength, stamina, durability and spiritual power, as well as allowing access to both more powerful variations of previous techniques and completely new abilities. Arrancar normally only return to their human form when they reseal their Hollow powers; doing so without resealing, though possible, is a permanent change comparable to amputating a limb. There are two reasons Arrancar go through such trouble to seal their power: it allows them to maintain human form and to conserve their power in times of inactivity.

In most cases, Arrancar "lose" their zanpakutō after performing their Resurrección. By which, they no longer carry any kind of one or two handed weapon - the sword is replaced by other natural weapons such as claws (Shawlong Kūfang), pincers (Findor Carias), tendrils (Szayel Aporro Granz), or just plain fists (Choe Neng Poww). However, there are some exceptions - nine to be exact; seven out of these nine have been Espada.


 * 1) Starrk has a pair of black pistols. He is the 1st Espada.
 * 2) Barragan Luisenbarn uses a double-headed axe with attached chains. So far, its the only weapon that vaguely resembles his zanpakutō in its pre-released form. He is the 2nd Espada.
 * 3) Tia Harribel uses a pata-like weapon shaped like a shark tooth. She is the 3rd Espada.
 * 4) Nelliel Tu Oderschvank uses a white double-sided lance. She is the former 3rd Espada.
 * 5) Ulquiorra Cifer carries a white "spike-blade" that he can seemingly generate from his body, which can also be used as a projectile if necessary. He also possesses a second released form, but he loses the weapon. He is the 4th Espada.
 * 6) Nnoitra Jiruga can wield up to six separate scythes with yellow tassels on each end. He is the 5th Espada.
 * 7) Aaroniero Arruruerie wields Kaien Shiba's Nejibana alongside his own octopus-like zanpakutō, Glotonería. He is the 9th Espada.
 * 8) Mila-Rose uses a large two-handed sword after her release. She is a Fracción.
 * 9) Rudobōn carries a bolt-like staff in place of his zanpakutō. It is unknown if the staff has the ability to cut. He is the leader and creator of the Exequias.

As Ulquiorra Cifer, the 4th Espada, has demonstrated there is a second form of Resurrección called "Segunda Etapa"; however, he claims to be the only Espada with this ability, and that even Aizen had no knowledge of the transformation. Since he states it as another level of power, it can be assumed that any Arrancar can achieve it.

Trivia

 * The only known Arrancar with a second Resurrección is Ulquiorra Cifer.
 * While most release commands are either one or two words, the release command of Findor Carias is almost a whole sentence, making it the longest release command for an Arrancar so far in the manga and anime.
 * So far, almost every Arrancar who used Resurrección has taken the shape of, or been named after, an animal. The only Arrancar who do not take the shape of an animal are: Edrad Liones, Charlotte Cuuhlhourne, Dordonii Alessandro Del Socacchio, Barragan Luisenbarn. Yammy Rialgo may also be in this category, but his released state has yet to be shown clearly.
 * Both Aaroniero Arruruerie's and Mila-Rose's release commands translate as Devour.
 * Among the Espada, three members have unique Resurreccións: Ulquiorra Cifer has a second release, Yammy Rialgo's number changes from 10 to 0, and Starrk needs to merge with Lilynette rather than unseal his zanpakutō.
 * Almost all Resurrección names are Spanish words. The only exception to this is Gantenbainne Mosqueda's Dragra.
 * Pesche Guatiche is the only Arrancar who has revealed his Zanpakutō's name, but not actually released it.
 * Gantenbainne Mosqueda is the only Arrancar to activate his Resurrección without revealing his release command.
