What makes you think this will happen?
Genuinely curious
Gut feelings partially but at this point:
- Ulti vs. Usopp/Nami was only portrayed without P1 really assisting, implying that both of them is just way too much but if they work together they may be able to take out Ulti again if revisited (assuming it will because now Ulti pissed at Nami)
- This leaves P1 alone, and something about P1 reminds me of an actual monster. I think its his hybrid or the way he acts, but something about him screams a battle of monsters vs. Chopper. Not to mention Chopper sort of makes up the "trio" of weakling i guess, but he is strong enough to hold his own against a physically capable fighter like P1.
- Ruling out Sasaki/Franky may honestly imply Brook vs. WW, as both Brook and Franky are regarded to be "similar" in strength, even having relatively close bounties. So they wouldn't make sense i guess.
- Leaving Robin for Black Maria if she takes over for Sanji.
Obviously all guesswork, I just think its the safest path for everyone to grow significantly and still have the 6 Supernova Captains be relevant for Yonko battles (assuming Apoo/Hawkins flip sides). The matchup counts work well and are pretty consistent (Beasts Pirates are not as messy in terms of heirarchy like the BMP). This is assuming:
- The rest of the Numbers are fodder/just designs Oda wants to draw (since even Franky can 1 shot them)
- The majority of the BMP won't be relevant (but still could be who knows)
- Orochi's top subordinates (Fukurokuju/Hotei/etc) and himself are taken care of by other people (Shinobu, Hyougoro, Momo, Otama, etc)
