I think after each of those fights with Ichigo and "Juhabach" his power increased slightly he sort of lost conciousness, although not the way he is now, but he might have got some power boost. Although i dont think any beating he has had thus far is a bad as the one Unohana is giving him now. I mean, she stabbed him in the throat and stuff, nasty business, wheras "Juhabach" just seemed to have punched him to mush. And Ichigo, cut him a little. I think Kenpachi's Zanpakuto will revolve around blood or something, im half expecting a susanoo look alike in all fairness, but i think its mainline ability is extreme blood clotting.
