When a Hollow becomes an Arrancar, his/her powers are sealed within a weapon,usually a sword, though it can take a different form, depending on the Arrancar. When they release their weapons' seals, they unleash their true power and their true form. The only time they can return to Human form is when they reseal their powers in sword form.
Whereas Shinigami Zanpakuto almost always take the form of a katana or wakizashi in their sealed state, Arrancar Zanpakuto can be more unique, ranging from western-style swords and axes to scythes, though some Arrancar do possess a katana.
Because their powers are sealed in their Zanpakuto, an Arrancar's release will usually transform their body into a Hollow-like form, allowing them to use all of their abilities freely. This form usually reflects what the Arrancar looked like before becoming Arrancar, although to highly varying degrees. A Resurreccion 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. Some Arrancar even gain new weapons as a part of their released form.
Resurreccion: Segunda EtapaEdit
A second stage of Resurreccion, which is overwhelmingly more powerful. To date, Ulquiorra Cifer, the Cuarto (Fourth) Espada, is the only Arrancar to have achieved this powerful form, though in the original timeline Tercera (Third) Espada Tia Harribel has declared her intention to attain Segunda Etapa as well. Likewise, Ulquiorra has decided to reveal the form to his fellow Arrancar in the alternative timeline.
