Aside from this being one of the best fights you'll ever read in a shounen
Heres some important notes from this chapter:
Luffy is confirmed to be all white in his Awakening form. Pure White hair and Body. Which is a massive relief because everyone thought he had Golden hair and I really hated that. We don't need another Super Saiyan transformation reference. That would have felt generic. This feels WAY more unique. Plus Luffy being All White is another Direct Contrast to Blackbeard. The Black & The White, The Light & The Dark etc etc. The same way Whitebeard was. Which sort of suggests that Luffy is the next "Big Good" of the Pirate World the same way Whitebeard was.
Kaido confirms for us that, Luffy is coated in BOTH Armament AND Conqueror's Haki. This is a reminder that Haki is invisible and it's not always going to be shown to us.
Last and most importantly, Kaido is outright confirming that Zoan types Transform when they Awaken. Which is a huge deal. Because it suggests that, if Kaido has Awakening then he has another Transformation up his sleeve.
This confirmation implies something else. He says specifically that Paramecias Transform the Environment, and that Zoans Transform. But he never confirmed what Logias do when they Awaken. Meaning that their Awakening is likely completely different than the other 2 types and NOT changing the environment like people initially thought. So Aokiji & Akainu's feat on Punk Hazard is NOT a product of their Awakening.
