User blog:SaxyAndIKnowIt/Ichigo Hollow Powers?

Okay, so I've been reading around and I keep seeing how Ichigo first got his Hollow powers when he became a Shinigami in the Shattered Shaft. However, when he first fought Renji, he went berserk like he does when his inner Hollow takes over. Since that happened before he gained his own Shinigami powers, wouldn't that mean that Hollow Ichigo came to be before Ichigo almost became a Hollow? I think it was actually when Rukia transferred her powers to Ichigo, because if it was the Hogyoku that caused her to give him all of her power instead of only half like she intended, wouldn't it have also made Ichigo a Visored?
