Yeah, that explains a lot too. But what I'm wondering about is how was Aizen able to create hollows? He already knows some forbidden hado techniques and he can kill em without drawing his sword so I don't question his power. It's just I don't know how he was able to create such hollows, each with a special, distinct ability. That episode when he went after Rukia he was explaining the barrier between a hollow and a soul reaper. I understand he made those hollows hoping that he could break that barrier but how would he be able to fuse with the hollow and still maintain his body and mind without it doing the same? It's all too complex for me to comprehend.

Hopefully you guys can give me an explanation thats more thorough.....
