User blog comment:Tekkphreke/Theory on Ukitake's Bankai/@comment-5657895-20130913041940

Given his reputation I'm expecting something major. I was holding the theory that his bankai or another shikai power of his would be to reverse damage he sustains onto his opponents.

We know Ukitake is powerful, just limited by his illness, which is why I think the Lotus-Buddha Shrine thing going on with Ukitake might be a ritual to suppress or cure his illness. Then we can expect really big things from Ukitake.
