I thought his Bankai was cool though, I liked how he ripped off Gerard arm with just his teeth. But I did expect his Bankai have something to do with his body changing though. But I hope we get into more detail with it next week though, I don't think Gerard out yet though, maybe he can reform and I still liked to know what abilities the "Heart of the Soul King" can do, like what does it Govern?

In addition we don't know what the name of Kenpachi Bankai is though yet, and to be confirmed if Yachiru is related to his zanpukto (I'm sure she is, but it hasn't been stated in the manga), so hopefully this chapter was to show off Kenpachi improved strength and power.
