User blog comment:Godisme/My Take on Isshin/@comment-1752519-20100328220417

i agree that isshin must be stronger than a normal captain, much stronger actually i mentioned it in an answer i gave long ago in the wikianswers, altough i dont really remember the questions, also thefact that he is smiling like that also give the impression so it has made the idea of isshin being uber strong even stronger in my head reasons 1) he gave me that impression since he slayed grand fisher (along with uryus dad) 2 he is the father of ichigo, call it cliche but in anime the dads always turn out to be big shots ex.(yusuke and raizen from yu yu hakusho, naruto and minato from naruto, luffy and dragon from one piece)and i have already stated that it is not unbeliveable that aizen has had manipulated everything like he has stated i even posted that in lias blog about the edge of silence chapter, it is highly predictable how certain things will react, like it is obvious soul society would go for rukia, he could also manipulate wich squad was sent, etc. and in character terms, kenpachi, byakuya, grimmjow and ulquiorras fights where also very easy to make them happen
