*Appears* Well depending on how long further down the line it is, I wouldn't see why not unless told otherwise of course. Seeing that they aren't allowed at the moment, you probably should leave whatever part the Arrancar plays in the overhaul a mysterious. This is just in case they won't be able to be used at all so you can change it without fooling the readers.

Alright, thank you on the advice, but I was already one step ahead of you on not exactly introducing the antagonist as an arrancar so it can be easily changed in the future if need be.
