Incredible chapter!
* What's up with the thunderclouds? It is apparently possible for intense fires to create "volcanic" thunderclouds. By preventing water molecules from coming together violent storms can be generated. Could Big Mom and Prometheus be plotting such a disaster? Poor Kid and Killer!

* Kid, Killer, Law and even Kaido all witnessed Zoros strength and remarked upon his resilience. He might never become the strongest in the world but just like Rayleigh or Ben Beckman he will be an absolute powerhouse that is respected by all and coveted by opposing captains/fractions.
* Luffy has a way of beating Kaido now! But it seems far to easy... If it is that "easy" to beat Kaido why is he regarded as the worlds strongest creature on land, air or sea? There are surely some others with the same power such as Shanks, Whitebeard (previously), Big Mom, Akainu, Kong, Garp, Sengoku and Dragon. Perhaps Mihawk, Rayleigh, Blackbeard and Ben Beckman as well.
* I think this might be kind of like Water-Luffy vs Crocodile (fight 2). Yes, Luffy can damage Kaido but the opposite is still true as well and Kaido, together with Big Mom, seem to have the highest HP/Endurance in One Piece. I see Act 3 still ending in tragedy... Grand Fleet incoming? The marines? Blackbeard? In the end I see Zoro once again slashing Kaido and Luffy delivering the final blow in Act 4.
