I personally think he might be as powerful as the "Ulquiorra Killer" form when hollow ichigo took over. Meaning even a powerful opponent like Kenpachi will be defeated by him but in saying so when Kenpachi achieves bankai the playing field will be equal.

they'll probably train together as I believe that ichigo (and Kenpachi) will be too powerful to train with anyone else other than a Royal Guard
