What happened to his shikai and bankai in last fight? Did ichigo, isshin, urahra, yoruichi have some special powers and hypnotysm did not worked at all, so he had to relay on completely hogyuko.. or did i missed it somewhere? Ichigo at least didn't see the release, so he was unaffected. I'm not sure if it was ever said when Isshin was a shinigami, but I'm assuming it was before Aizen's time, so he wouldn't be affected either. Urahara and Yoruichi don't get a pass though as far as I can tell.
