Man, Kizaru looks so bad in this chapter against Sentomaru... First, he fails to defeat a guy who's already injured instantly, then he even struggles to defeat him, with his attacks not only being blocked and dodged, but he also gets hit himself. On the other hand, the Kaido vs. Kinemon fight makes Kaido seem like a god now, given the pathetic performance Kizaru had here.
Not to mention that Kizaru's laser attacks didn't do anything critical to Sentomaru's body, they were portrayed as just a regular explosion, and we've seen Big Mom casually withstand an explosion the size of an island without losing any limbs.
And we have to take into consideration that it's a Kaido without using his Devil Fruit power, while Kizaru was using his.
