User blog comment:Soulreaper1234/Why Do Ichigo & Aizen an Overpowered Hero & Villains?/@comment-1712587-20100830161327

I don't think Ichigo's overpowering is out of the blue at all. we all saw what the uber hollow did. so far in the story nothing, including Aizen has shown anywhere near that kind of raw power. It totally and absolutely destroyed Uliquiorra who had the segunda epta (spelling<??) release which arguably put him at the top of the Espada chain. Kubo is a master story teller and would not have gone to such great lengths to show off Ulqi's vast power before having the uber hollow destroy him without breaking a sweat.

on the other hand because of this tremendous power that ichigo had the possibility of harnessing some thing had to be done to put Aizen in the same league. lets face it the hollow could have Aizen'd Aizen if it came to a one on one encounter, considering Isshin pushed Aizen to the "limits of his shinigami self" Kubo needed to get Aizen to a point where he was so immensly powerful that he stood on even - if not higher - grounds than the hollow. I know it's been slightly painful and at time tiring to watch every character take a pop but we really needed to get to a point where it was completely apparent that Aizen can only be beaten by Ichigo's trump card.

now of course i'm veering way off into the realm of pure speculation here as we don't actually know what power Ichigo has attained yet but suffice to say Ichigo in the uber hollow form displayed the most incredible destructive power seen in the whole of bleach and we still need to believe Ichigo will be an underdog in the fight so that is why Kubo has gone down the road he has.
