User blog comment:Rejuvenation/Strange things in Bleach/@comment-44061-20100221161314

1.) Your going from the stand point that Szayel is an expert on Zanpakuto, he maybe the scientist of the group but he mentions that he has no data on Mayuri's zanpakuto and he states that its the fact that his bankai materialized as a corporeal creature that allowed szayel to gain control over it. So it was an observation not a fact as the manga he does not say organic just corporeal which anyone could have stated by simply witnessing it.

2.) Your initial point was that his bankai was supposed to disappear when he sustained alot of injuries. But that notion is incorrect cause it has never disappeared in any fight. Now if your referring to the damage he takes, yes his clothing is part of his bankai and its damage is a reflection of his depleting reiatsu as i said previously. It has nothing to do with reiatsu flowing out of his body or anything like what happened to Nel. Its from using it in general just anyone would over time. Im not entirely sure what the issue your bringing up is.

3.) we do know for a fact that Aaroniero was 9th espada, it has been said many times that the espada are ranked in according to their power. So it apparently didn't matter whether he had 1000+ hollow powers or if he was attacked out of the blue. We do know what level of power he was in comparison to the other espada. Some things could have been different but it doesn't change the fact of how powerful he claimed to be and what his power was ranked dont synch up. He said himself his evolutionary ability is all that allowed him to be an espada if he was really powerful with all those abilities he wouldn't have been bottom guy on the totem pole.

4.) It's quite obvious Aizen didn't seem to care if he lost Arrancar, they were just tools and when they proved to be useless he took out the last one standing himself. Beyond that the situation was apparently according to his plans and went off perfectly regardless if we think it would have been more logical to take Ichigo and his friends out when they first arrived. He appears to like toying with people cause he can even when it simpler to take them out easy and quick. As I said even if they had sent more captains either way wouldnt have made a difference if they were in his way or not, all they have done so far is take up his time.
