My thoughts:
- I don't see Apoo, Drake, Hawkins going up. However, I wouldn't rule it out since Hawkins said he has some trump card (may use it on the MC).
- Marines won't show up this act, maybe tail end of Act 4 w/ SSG on Wano Mainland.
- Drake, Apoo can't do shit to Kaido. Kaido ~ Mythical Zoan, Drake ~ Ancient Zoan (Ryuo? Idk) ; Apoo is a joke
- Wano is a parallel to Thriller Bark (I'm sure you already know this, so I'm not gonna explain)
- This fight with Kaido will last until the dawn, and the 9 Shadows will be from Asura Silver Mist (maybe that's the reason Oda never used it Post Time skip), given Zoro's relevancy in this mammoth of an arc.
- I think the real threat here was Big Mom all along. I have confidence that the Supernova will take down Kaido ~extreme diff ofc~ but he will go down.
- Luffy vs Big Mom will be the hardest fight Luffy will have in the series yet and it will be Solo or with Law.
- I see Yamato fighting Smoothie when they land and Onigashima is destroyed against Wano mainland, but seeing her up top is not farfetched.
- And obligatory, Sanji will not be on the roof. He will fight Queen w/ Drake, Apoo, Hawkins? And he might also fight Perospero bc I don't trust that rabbit mink to defeat a 700M berry Veteran when her benefactor died w/o even defeating him.
TLDR: Apoo and Drake can't even tickle Kaido's nutsack. Hawkins maybe asspulls some OP shit. Asura Zoro ~ 9 Shadows
