Right, now we've got most of Kaido's crew, here's my Strawhat predictions
Luffy vs Kaido. Kaido
Zoro vs King. Swordsman
Sanji vs Queen. Perv
Jinbei vs Jack. Fishman
Franky vs Sasaki. Based on build alone Sasaki seems like someone who Franky can really go toe to toe with
Brook vs Who's Who. Sword fight
Chopper vs Page One. Both seem to be the little brother types of the crew
Nami vs Ulti. Girl fight.
Robin vs Black Maria. Both seem more mature women, Robin can go Gigantesco Mano mode.
And I think Ussop is the one to miss out this arc- perhaps why he unlocked CoO in Dressrosa. Will get another sniping feat though, and maybe will have something to do with the Numbers if the Oni are a separate race of Giants.
Also others will jump in on the fights, but the Strawhats will be doing most of the work and landing the finishing blow
Usopp v. Orochi. Embrace it. Usopp being "Susanoo" would be fucking hilarious
Edit:
I am curious as to who will fight all of BMs monsters, but my guess would be the remaining Supernova at this point. There are basically 6 Monsters essentially and 6 Supernova outside of Luffy/Zoro
- Killer vs. Daifuku?
- Hawkins vs. Oven (if he's at Wano)?
- X Drake vs. Perospero?
- Apoo vs. Campote? (We don't know Apoo's rank yet or what he even is in Kaido's group, nor Campote's power and if that would even be a good matchup)
- Law vs. Snack (both Sword users; though Kid and Urogue already have defeated the character it seems, 3rd times a charm lol)
- Kid vs. Smoothie (only if Luffy fights the Ace/Kaido's Son if it's a legitimate thing)?
I feel like these would be impressive feats for them and an opportunity to have Oda show off these characters more in interesting ways before the Yonko.
