User blog comment:Captain Brooks/My thoughts on Aizen sama./@comment-1752519-20100328233931

aizen is my favorite villain of any anime/manga series, there is no such things as overpowered, in reiatsu for example ichigo + hollow ichigo should have more reiatsu than aizen by far, after all each has theyre own reiatsu and each has had enough power to overpower captains (hollow ichigo vs byakuya, ichigo vs kenpachi) theyre reiatsu (wich at this point should be even higher) should surpass by a lot aizens, ichigos reiatsu alone is around double a normal captain + hollow ichigos is always around ichigos max reiatsu ad he doesnt suffer ichigos constant mental crisis, so if he used both his max power + his hollow max power he would surpass aizen, this also makes ichigo the strongest character in the series at this point (in sme way)

p.d. what i mean by this is that ichigo + hollow ichigo is part of one character, not that one of them alone is stronger than aizen but since theyre both part of the same spirit/body, etc. they count as one and in that case the 2 in 1 power surpasses aizen by far
