Aye, but didn't you just say it includes the arm, of which is fused with Hitsugaya's arm? I'm sure he could use some of his reiatsu to hold back the bleeding, like Ichigo had done against Kenpachi. Then just have the ice arm act as his own during the fight. Anything's possible with Tite Kubo at the helm.
I really wanna see Unohana somehow take down Yammy. It would just be hilarious.
Oh, and is the King supposed to be super strong? I mean, he has an elite force guarding him, so if he was so strong, why would he need them? I'm guessing he's pretty weak, maybe even lives in disguise among the Shinigami. I'm thinking Hanatorou is the King.
Edit: One more thing. Would Wonderweiss possibly show up and save Yammy?
