Bleach Chapter 523 Discussion

One thing that bugs me, is that he claims he created every single one of the zanpakuto in existence.. That they all started as the empty shells. Just how many uninfluenced zanpakuto did the hollows collect for Arrancar to start showing up?.. I can accept aizen bringing a bunch for when he made arrancar, but the other ones..



And ichigo.. someone had an oversized uninfluenced zanpakuto laying around for when he got rukia's powers? If he had actually overwritten rukia's zanpakuto, then that means that none of the captains need to worry about loosing bankai since they can just pour their soul into a new zanpakuto, since rukia still has a fully functioning zanpakuto...
