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 a of sword. 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 sword - the sword is replaced by other 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 - 9 to be exact; 7 out of these 9 have been Espada. They are listed in chronological order of their release:


 * 1) Aaroniero Arruruerie wields Kaien Shiba's Nejibana alongside his own octopus-like Zanpakutō, Glotonería. He is the 9th Espada.
 * 2) Nelliel Tu Oderschvank uses a white double-sided lance as her resurrección. She is the former 3rd Espada.
 * 3) Nnoitra Jiruga can wield up to 6 separate scythes with yellow tassels on each end. He is the 5th Espada.
 * 4) Mila-Rose uses a large two-handed sword after her release. She is a Fracción.
 * 5) Rudobōn carries a bolt-like staff after releasing Árbol, 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.
 * 6) 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.
 * 7) Tia Harribel uses a pata-like weapon shaped like a shark tooth. She is the 3rd Espada.
 * 8) Barragan Luisenbarn uses a double-headed axe with attached chains. So far, its the only weapon that vaguely resembles an Arrancar's Zanpakutō in its pre-released form. He is the 2nd Espada.
 * 9) Starrk has a pair of black guns. Starrk is the primera Espada.

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 and Arrancar so far in the manga and anime.
 * So far almost every Arrancar who used Resurrección has taken the shape of 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, and most probaly Yammy Rialgo.
 * Both Aaroniero Arruruerie and Mila-Rose Release command translate's as Devour.
 * Among the Espada, three members have unique Resurreccións: Ulquiorra Cifer has a second release, Yammy Rialgo's number change 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.
