Also, im looking threw episodes AND I found something interesting, at the end of episode 146, Gin explains the arrancar class system. Quoting him -
"Toay we'll review the Arrancar class system"
"Of the three three Menos classes, the vastro Lorde are the only ones guarnteed to take human forms."
"Most of the lower-level Adjuchas and Gillian classes end up with bodies that aint fully human."
Pictures of the first hollows Ishida and Chad fought when coming into HM are on the screen...(

Which leads me to believe the writers don't even know what the hell is going on... Heh
