User blog comment:Soulreaper1234/Why Do Ichigo & Aizen an Overpowered Hero & Villains?/@comment-44061-20100828163731

The problem is Kubo has created a series that is character driven. The stories by his own creation are designed around the characters instead of the other way around. He has created a significant supporting cast. His on the fly creating method does have holes though.

As TVthePunisher mentions DBZ was a defining method in which power levels got out of hand and this pattern seems to be repeated in Aizen and Ichigo. The issue here is that Ichigo hasen't neither significantly trained or deserved such power, there was no realistic build up, it was just handed to him. Then he is beating characters centuries old with more power and skill with no reasoning behind it. Then he is shown to be inconsistent in his power, where he once could be a captain he then can't. Aizen on the other hand was overpowered before the current arc. His zanpakuto was the reason behind that. It has no real place in the bleach universe. If primary combat is fighting it doesn't do this, it has no limit to its effect in regards to time. Its not even consistently shown its release. There is no real weakness or drawback, short of being blind. Then the total destruction of captains & vizards with ease without so much as releasing or anything. Simply beating back bankai, it was just unrealistic. then unnecessary transformations, like he wasn't overpowered enough what did he need to transform for, that was the hitch in the story why was that necessary wasn't the plan to use the power he already possessed and make the key.

The most significant issue for me is the future of the series. In such a character driven story. I understand ichigo is the main guy but the story was built up about the importance of Soul Society and Shinigami as without them the world falls. So what significance does any other character have with these ridiculous power levels that Ichigo and Aizen profess. I would figure everyone must be elevated up to the same level or Ichigo will have to severely come back down. From the character development and story given to use so far, what is currently taking place doesn't make sense for series continuation. I guess we will just have to see what Kubo does.
