User blog comment:Silver-Haired Seireitou/Sake Time with Sei - Can Arrancar Use Kidō?/@comment-5778280-20140413165809

Whilst Visoreds can use Cero and Hierro, I truely do not believe that Arrancar can use Kidō. If you think about how they are composed, their techniques make use of spiritual pressure instead of spiritual power. Bala, Cero, and even Hierro are all basic utilizations of spiritual pressure. Now, if you were to consider the fact Arrancar can manipulate spiritual particles, I guess you can come to the conclusion that they share the same abilities as both Shinigami and Quincy. You see, in order to control spiritual particles, doesn't one have to imbue their spiritual energy into the particles? If so, then the fact Arrancar can control their spiritual energy, should be enough proof that they can use Kidō. Though, I don't think it's that simple. I feel like there is much more behind their existence than what we actually know. For instance, why can't a Quincy harbor the power of a Hollow, yet an Arrancar can utilize a few of the abilities present for Quincy? If their relationship is as obscure as that, I can only imagine the relationship they possess with Shinigami. Though, what do we know? For all we are aware, Cero and Bala may be their own unique application of Kidō.
