One thing I want to point out for all the power scalers out there: the last page of this chapter is the first time we saw Kaido do Thunder Bagua with two hands. When he hit Luffy, it was a one handed forehand, and when Yamato hit Ulti, it was a two handed backhand. It could just be that the backhand swing uses two hands and the forehand is one handed (like most tennis players use), but it could also be that Kaido is using his strongest Thunder Bagua only now.
