Getting back to the topic.

what was the topic?..............

O yes, Ichigo's bankai.

What about Byakuya's Bankai. I mean his Shankai was fucking awesome as we have seen. Scater......

Waiting to see his Bankai. His Bankai will have to be a badass one if he has to resist Ichigo's Bankai. Also he has a vast exprience in that department.
