I too hope Kenny shows up soon and bifurcates some Sternritters :P

Mask De Masculine seems to be pretty much a Quincy-version of Yammy, I don't see him being in the need of any particular character development. I wouldn't have any problem with it if Kenny shows up to face Mask and only leaving him the time to state his name, letter and epithet before cutting him down. I'm fairly sure his epithet is The Strength anyway, given his muscular body and the way he attacked Renji when he first showed up.

BTW, I believe it was established long ago that the jagged, worn sword is Kenny's actual Shikai. I don't think much will change in its appearance, I'm not even sure he will manage to get a sealed form of it. It kinda suits him best with a full-time-Shikai.
