Resurrección

Arrancar, are Hollows that have removed their masks and gained Shinigami powers, have Zanpakutō and can perform something 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 who used it an animal-like appearance.

Because their powers are sealed in their Zanpakutō, an Arrancar's release will usually transform some or all of 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. 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. The reason Arrancar go through such trouble to seal their power is twofold: it allows them to maintain human form and conserve their power in times of inactivity.

In most if not all 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,) tendrils(Szayel Aporro,) or just plain fists(Pō.) However there are some exceptions-- 6 to be exact; 4 out of these 6 have been Espada and only half of the foursome still live. 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 was an Espada (deceased.)
 * 2) Neliel Tu Oderschvank uses a double-sided lance as her Resurrección, which gives it the appearance of Shikai upon release. She is a former Espada.
 * 3) Nnoitra Jiruga wields 4 separate Scythes similar to his sealed zanpakutō broken up. He was an Espada (deceased.)
 * 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 of the Exequias, not to mention their creator.
 * 6) Ulquiorra Schiffer carries a white "spike-blade" that he can seemingly generate from his body, which can also be used as a projectile if necessary. He possesses a second release form. He is an Espada.
