To ZeroSD, just to clarify. Grimmjow is a confirmed adjuchas based on his flashback and based on that same flashback Nakeem Greendina was a confirmed Gillian. However, Nakeem the Arrancar seemed to be held in higher regard by his companions then Di-Roy, who was confirmed adjuchas class arrancar but then Aizen referred to all of Grimmjow's faccione as Gillians. So certainly, not all hollows seem to arrancanize in the same way. Whatever they start off as.
