about arrancar numero nuevo (spoilers)
should he even be considered an Arrancar? if he is indeed kaien, then he is a shinigami who attained the powers of a hollow. he also has no mask at all, so he cant be "the broken mask." His zanpackto release does not seem to release his hollow form, and is more of a shinigami release. lastly, if that mask he wears in the beginning is his hollow mask, he seems to me able to take it off at will, unlike the arrancars who seems to have their mask fragments stuck. so far, only the vaizards have shown the ability to have a full mask and move them at will. SO what is he? arrancar or vaizard?
