I would prefer Isshin alive if you don't mind, Kubo-sama. How the hell else is Ichigo gonna transform from ZERO with hero powers to HERO with hero powers if he doesn't get advice from someone different, i.e. his own old man?

LOL the MiddleFingerOfDeath gave us some idea of Isshin's strength. Actually, it would be okay if Isshin matched Aizen blow for blow and Aizen manages to escape leaving Ichigo to scream, shout, clobber, cry and everything else possible to his Dad.
