Resurreccion (Spanish for Resurrection, Japanese for Returning Blade) is the release process which transforms an Arrancar into a Hollow-like form. Although an Arrancar's Resurreccion is sealed with the form of a Zanpakuto, it is entirely different from a Soul Reaper's Zanpakuto. While a Soul Reaper's Zanpakuto is the manifestation of their owner's soul, an Arrancar's Zanpakuto is actually a manifestation of their former Hollow selves, but this is only for Impureza Arrancars. Puro Nacido-class Arrancars however, because they were born Arrancars instead of transforming into Arrancars from Hollows like Impureza Arrancars, their Zanpakuto is a manifestation of their inner power, the full, unlocked core of their abilities.
Overview Pt 1: Fuerza de Resurreccion.
Fuerza de Resurreccion (Resurrection Force): When an Arrancar enters the Fuerza de Resurreccion form, a cloak of pure raw Reiatsu covers their entire body, with said Reiatsu cloak looking like an exact replica of whatever their Primera Etapa form looks like, which, once activated, the Arrancar's pupils brightly glow whatever color their Reiatsu is, and their Estigma grows into a newer, longer shape.
The Fuerza de Resurreccion form multiplies the Arrancar's power by 20x times its normal amount, as the Arrancar's abilities, power level, strength, speed, stamina, senses, and endurance are all greatly enhanced, such as Cero and Bala techniques, Sonido, Pesquisa, etcetera.
Fuerza de Resurreccion is achieved through the user using his/her own Reiatsu to surround their entire body with a cloak made up of their own Reiatsu. Those who have just achieved Fuerza de Resurreccion but have yet to master the new form have the Reiatsu cloak to be shaped an in incomplete form, which does not increase their battle power at all. But with intense training within the Fuerza de Resurreccion form, in time, their Reiatsu cloak begins to reshape itself into a complete, perfect form, which can multiply their strength and abilities by 20x their base form.
Overview Pt. 2: Resurreccion Etapa forms and Mode Changes.
Resurrección: Primera Etapa (Resurrection: First Stage): Resurreccion: Primera Etapa is the first basic stage of the Resurreccion transformation, and the prime Resurreccion form for the Arrancar race. Resurreccion: Primera Etapa is unlocked when an Arrancar seals the nuclei of his/her abilities within the form of a sword or a different type of weapon, whether if it is an unusual-shaped weapon, like Nnoitora's Zanpakuto or a regular, normal-shaped weapon, like an axe or a gun, or an inanimate object, such as braces, tongue piercings, or a glass paperweight, etcetera for that matter if possible. And in rare cases, Arrancar can also seal their Resurreccion in the form of another body, whether it be whole, or otherwise, such as in the form of a another Hollow/Arrancar body/being, whether animal or humanoid, with said being having his/her own consciousness and personality, examples being Aaroniero Arruruerie's Zanpakuto and Lilynette Gingerback respectively.
Only Impureza Arrancars, which are of regular Hollow, or Menos-class can seal their Resurreccions in the form of a body, whole/separate or otherwise, Puro Nacido-class Arrancars however CANNOT do this. Impureza Arrancar seal their Resurreccion forms once after they evolve from Hollows (whether Menos or Normal-class). Puro Nacido Arrancars however, if they become strong enough or when they reach a certain age, are able to create a Resurreccion form of their own by sealing the nuclei of their abilities within the form of a weapon (sword, axe, gun, etcetera) which is their Zanpakuto.
When an Arrancar performs Resurreccion, the weapon/body part/second being in which their Resurreccion is contained in, combines with the Arrancar and transforms him/her into a Hollow-like form, in which they are allowed to feely use all of their abilities, and part of their original Hollow form is restored (and in the case of Puro Nacido-class Arrancars, their full potential is unlocked) and the Arrancar is granted greater strength, various increases in speed, strength, stamina, durability, Reiatsu, and spiritual power, along with access to all of his or her original abilities, whether new or powerful variations of previous techniques. The power output increase in Resurreccion: Primera Etapa is colossal, as the new form is able to multiply the Arrancars power by 60x times its normal amount, and it skyrockets beyond the power of base form Arrancars. This is the first release of Resurreccion, Resurreccion: Primera Etapa. Resurreccion: Primera Etapa is the Arrancar equivalent of the Soul Reaper's Shikai.
Primera Cambio de Modo (First Mode Change): Primera Cambio de Modo is a sub-form of the standard Primera Etapa Stage. It usually occurs when an Arrancar becomes a different version of his/her current form. Primera Cambio de Modo's power exceeds regular Primera Etapa and is more powerful than the previous Primera Etapa mode, and has both more powerful variations of previous techniques demonstrated in Primera Etapa, and/or completely new abilities, along with a clear increase in power, which is increased tenfold. Examples of Primera Etapa, Cambio de Modo are Ggio Vega's Tigre Estoque El Sable and Yammy's Enraged form. It is obviously not Segunda Etapa, and while Primera Cambio de Modo's power exceeds normal Primera Etapa, it is nowhere near the immense power of Segunda Etapa. Cambio de Modo Resurreccions can also get additions to their names, such as Ggio Vega's Tigre Estoque El Sable for example.
Primera Cambio de Modo is a state of mental and physical perfection of the basic core of the Primera Etapa stage, as it is the complete mastery of the Primera Etapa form. In order to unlock the first mode change of Primera Etapa, the Arrancar must spend fourteen days and fourteen nights in their Primera Etapa form, and continue to train and improve their abilities and push them beyond their normal limits of the Primera Etapa level. And once after the Arrancar has completely mastered the basic Primera Etapa stage by perfecting it and its abilities through training, he/she will be able to unlock the Cambio de Modo sub-form instantly by transforming into a different version of their Primera Etapa form.
However, this doesn't mean that the Arrancar will automatically go into his/her Primera Cambio do Modo form upon entering into the Primera Etapa stage, the Arrancar will still be able to access the regular Primera Etapa form, but will also have access to the stronger Primera Cambio do Modo sub-form if said sub-form was needed.
Resurreccion: Segunda Etapa (Resurrection: Second Stage): Is the second form of the Resurreccion transformation, and the direct successor to the Primera Etapa form. Segunda Etapa is the advanced, legendary transformation of the Arrancar race, and it is assumed only by extraordinarily powerful members of the Arrancar race. Segunda Etapa is something only a few select Arrancar in existence have achieved, and although extremely rare, but completely possible, others were born with it rather than achieving it through training.
There are three requirements that an Arrancar must have in order to achieve Segunda Etapa. One, the Arrancar must have done immense, nonstop training, day and night in either his/her first released Primera Etapa form, or the Primera Cambio do Modo mode change should they have access to it, and gain a COLOSSAL amount of power, strength, speed, stamina, skill, endurance, and a great increase in both Reiatsu and Reiryoku in the process. Two, the Arrancar has to have completely maxed out/mastered his/her Primera Etapa form, as well as their Primera Cambio de Modo sub form should they have access to it. And because the Arrancar has maxed out his/her Primera Etapa/Primera Cambio de Modo form and sub-form respectfully, or has only maxed out their standard Primera Etapa form without every achieving the Cambio de Modo sub-form, he/she will potentially be capable of reaching the Segunda Etapa stage, given the correctly right circumstances. Three, the Arrancar must not have any weaknesses within his/her heart, he/she must fully embrace their true strength, and realize their full potential. It also requires a catharsis, a mental transformation that precedes the physical one. In other words, an Arrancar must learn to accept to use the power that they have, and throw away any and all fears that they have in doing so.
Arrancars who have achieved the Primera Cambio de Modo sub form, and have maxed it out will definitely be more powerful than Arrancars who have not achieved the Primera Cambio de Modo sub form, but at the same token have maxed out their basic Primera Etapa form, because Arrancars who have completely maxed out their Primera Cambio de Modo sub form will definitely have more potential.
In order for an Arrancar to have been born with the Segunda Etapa stage, he/she must have been born from two Arrancar parents that already have achieved the second Resurreccion stage. When two parents who already have the Segunda Etapa stage produce an offspring, then said offspring will have already born with the Segunda Etapa stage. Arrancars that were born with the Segunda Etapa stage are ten times more powerful than those who were born without the Segunda Etapa stage. Because (more coming soon).
The Segunda Etapa form gives the Arrancar user six times the strength of Fuerza de Resurreccion, three times the strength of Primera Etapa, and two times the strength of Primera Cambio de Modo, as the power of Segunda Etapa skyrockets FAR beyond the power of the Fuerza de Resurreccion, Primera Etapa, and Primera Cambio de Modo forms. As the form multiplies the Arrancar's base power, Reiatsu, and Reiryoku by 340x times its normal amount. In Segunda Etapa, the Arrancar's speed, strength, endurance, and stamina are all pushed FAR beyond the normal limits of base, Fuerza de Resurreccion, Primera Etapa, and Primera Cambio do Modo, and has both more powerful variations of previous techniques demonstrated in the Primera Etapa/Primera Cambio de Modo forms, and completely new abilities. In other words, Segunda Etapa is basically the Arrancar equivalent of the Shinigami's Bankai, and it can only be accessed by High-tier/Espada-leveled Arrancars.
Segunda Etapa can also have an effect on the Arrancar's personality. While most Arrancars who use Segunda Etapa have full control over their personalities, albeit with a few personality changes, some Arrancars' personalities can change either a little or a lot. For example, an Arrancar who is good, honorable, and benevolent, can be become ruthless, vengeful, and overcome with complete rage and hatred, and any Arrancar that was already ruthless and cruel to begin with has his/her ruthlessness and cruelty amplified. Another example would be that an Arrancar can completely lose all aspects of his/her personality, and can become a mindless, demonic, ruthless, and in some or most ways, a sadistic warrior solely bent on eliminating the enemy as quickly as possible. This is mostly for Arrancars that have just achieved Segunda Etapa, but have yet to completely master the new form. Most Arrancars that have completely mastered the Segunda Etapa form not only have full control over their personalities, but are also more powerful than those who have not yet mastered Segunda Etapa. However, even some Arrancars that have full control and mastery over the Segunda Etapa stage can still experience the personality change side effect of the Segunda Etapa form, albeit to a far lesser extent than Arrancars who haven't mastered the Segunda Etapa form.
Segunda Cambio de Modo (Second Mode Change): Segunda Cambio de Modo, like Primera Cambio de Modo, is a sub-form of the standard Segunda Etapa Stage. It usually occurs when an Arrancar becomes a different version of his/her current form. Segunda Cambio de Modo's power exceeds regular Segunda Etapa and is more powerful than the previous Segunda Etapa mode, and has both more powerful variations of previous techniques demonstrated in Segunda Etapa, and/or completely new abilities, along with a clear increase in power, which is increased tenfold.
Segunda Cambio de Modo is a state of mental and physical perfection of the basic core of the Segunda Etapa stage, as it is the complete mastery of the Segunda Etapa form. In order to unlock the second mode change of Segunda Etapa, the Arrancar must spend twenty days and twenty nights in their Segunda Etapa form, and continue to train and improve their abilities and push them beyond their normal limits of the Segunda Etapa level. And once after the Arrancar has completely mastered the basic Segunda Etapa stage by perfecting it and its abilities through training, he/she will be able to unlock the Cambio de Modo sub-form instantly by transforming into a different version of their Segunda Etapa form.
However, this doesn't mean that the Arrancar will automatically go into his/her Segunda Cambio do Modo form upon entering into the Segunda Etapa stage, the Arrancar will still be able to access the regular Segunda Etapa form, but will also have access to the stronger Segunda Cambio do Modo sub-form if said sub-form was needed.
Ultimo Resurreccion Modo Ráfaga (Ultimate Resurrection Burst Mode): Ultimo Resurreccion Modo Ráfaga is a powerful form similar to the two mode changes of both the Primera and Segunda Etapa forms. Ultimo Resurreccion Modo Ráfaga is when an Arrancar in his/her Segunda Etapa form is completely energized by a massive quantity of spiritual energy/Reiryoku in order to transform into an even more powerful variant of themselves. Ultimo Resurreccion Modo Ráfaga is the ultimate power that exceeds Segunda Etapa, even though it may just be similar to a mode change, like the Cambio de Modo sub-forms of the Primera and Segunda Etapa forms where an Arrancar is able to transform in order to attain greater power. However, Ultimo Resurreccion Modo Ráfaga is far superior to the Segunda Cambio de Modo sub-stage. A Ultimo Resurreccion Modo Ráfaga-formed Arrancar retains a similarity to their original Segunda Etapa/Segunda Cambio do Modo form(s), but has brand new attacks, along with an immense clear increase in power, along with an aura of their own Reiatsu color emitting from their body. In this new form, the Arrancar's full potential is completely unlocked.
Segunda Etapa Ascensión (Second Stage Ascension): Segunda Etapa Ascensión is a release process where an Arrancar can completely bypass/skip the intermediate Primera Etapa/Cambio de Modo stages, and head straight into the Segunda Etapa stage. It is done when the Arrancar declares "Segunda Ascendió" along with the release command, followed by the name of their Zanpakuto.
Overview Pt. 3: Resurreccion Formulas:
Resurreccion Formulas: The Resurreccion formulas are into about how each different Resurreccion form, increases an Arrancar's strength, speed, stamina, etcetera by the amount of. Such as Primera Etapa for example, Primera Etapa increases and multiples an Arrancar's battle power by 60x percent.
Fuerza de Resurreccion: Increases an Arrancar's strength by 20x times their base form.
Resurreccion: Primera Etapa: Increases an Arrancar's strength by 60x times their base form.
Primera Cambio de Modo: Increases an Arrancar's strength 10x times their regular Primera Etapa form.
Resurreccion: Segunda Etapa: Increases the Arrancar's strength 120x times their Fuerza de Resurrección form, 180x times their Primera Etapa form, and 40x times their Cambio do Modo form.
Segunda Cambio de Modo: Increases an Arrancar's strength 10x times their regular Segunda Etapa form.
Ultimo Resurreccion Modo Ráfaga: Increases the Arrancar's strength 40x times their regular Segunda Etapa form, and 30x times their Segunda Cambio de Modo form.
Extra Info: Espada-leveled Arrancar Resurreccions are FAR more powerful than ordinary, Numeros, Fraccion, and Privaron Espada-released ones. Arrancars can still master and max out the basic Primera Etapa form without achieving the Primera Cambio de Modo form. Which will not only result in the Arrancar's basic Primera Etapa form tapping into a VERY good portion of the Primera Cambio de Modo sub-form's power, but will also result in the Arrancar's basic Primera Etapa form's strength being permanently boosted to Primera Cambio de Modo tier, and as a result, the Arrancar will never achieve the Cambio de Modo sub-form because they have already permanently drew out the Cambio de Modo power in their regular Primera Etapa form. Also, complete mastery of the first Resurreccion/Primera Etapa form draws out more power in the first form, (more coming soon).
An Arrancar that had already broken through Segunda Etapa, even though temporarily, the result will be that their Primera Etapa/Primera Cambio de Modo forms will be 10X more powerful than other Primera Etapa/Primera Cambio de Modo-released Arrancars without Segunda Etapa. The Arrancar's base and Fuerza de Resurrección forms will also rise above the limitations. Segunda Etapa is ONLY accessible to High-tier/Espada-leveled Arrancars that have hit the apex of the first Resurreccion/Resurreccion: Primera Etapa/Primera Cambio de Modo forms powers. Also Segunda Etapa does not boost Primera Etapa/Primera Cambio do Modo; it actually replaces them with something that is thrice/twice as powerful.
