This arc made me go back to old chapters and even episodes of Bleach and piece together everything. I always knew Hollow Ichigo/white had a bigger roll in the plot then just a Hollow Ichigo uses. If you read back to the fight with Hollow Ichigo during the Vizard training or watch it. Hollow Ichigo was the most proficient at using Zangetsu and Tensa Zangetsu. Even Ulquiorra said that Getsuga Tensho reminded him of his cero. Heck even Mugetsu looks like a cero. "Juhagetsu" said that Ichigo has been using only a fraction of his power the entire time. That must be include the fight  with Aizen. I really want to see Ichigo at full power.

Now the big question is. Is he stronger than Zaraki at full strength with full control of his Zanpaktou?
