At least for the beast pirates, I've been pretty adamant in these matchups. If the BMo do actually come through and are involved to distract Law and the other Supernova, then that would be awesome. If Luffys crew is singlehandedly taking down Kaido's side. They can take down Big Mom's.
Yonko:
Luffy vs Kaido
Yonko Commanders:
Zoro vs King
Sanji vs Queen
Yamato vs Jack
Veteran Executives:
Jinbe vs WsW
Franky vs Sasaki
Robin and Brook vs Black Maria
Nami and Usopp vs Ulti
Chopper vs Page 1
Essentially Choppers matchup entirely depends on Page 1 being present or if Drake is controlled by Queen somehow (virus tech) to force them to fight. Either Page 1 fights Chopper or continues to fight Usopp, IF he recovers. Yes, I assume Yamato is joining the crew, thus is warranted a fight, potentially quick enough so she can go and at least confront Kaido. She's heading towards the mansion so Jack is possible if she decides to save Inu.
And before anyone scoffs at Zoro vs King as some "downgrade", realize the same shit is happening to Killer right now. He fought two Yonko and is now matched up with Hawkins (for now). The same could potentially be said for Zoro.
If by some chance the BMP become involved, there are 5 Executives total that can go with Law, Killer, Drake, Hawkins and Apoo:
- Perospero
- Snack
- Smoothie
- Compote
- Daifuku
With Kid fighting BM, the dynamic can work. Though it's a question of when and how. Hawkins and Apoo would have to switch sides. Her ship would somehow have to appear on Onigashima or the island crashes soon and they arrive at mainland Wano. We can't even truly confirm if Oven isn't present (though unlikely), but the rest of her crew is effectively fodder outside of these 5 and Oven, Cracker and Katakuri, which is interesting because that is a total of 8 Executives for her crew and Kaido's (when you discount Drake).
All in all I'm more confident in the BP matchups because they are very likely going to just strawhats imo.
