As Ulquiorra Cifer, the former 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. Must have over 400 points to come here and apply for one.
