I think that Who’s who has the biggest potential from the F6. He’s fighting Jinbe for some time and Jinbe is extremely strong. It’s all speculation because Oda hasn’t shown much
Who's Who & Sasaki are the only ones who got acknowledged. That could be because of their strength or possibly because of their possoble connection/relationship to the strawhats they're fighting.
It could be a way to rank them but also a way to highlight which flying 6 might have more importance besides a simple match up.
& if you want to use them to rank then I can't say they're wrong because you can argue black Maria is the weakest flying 6 simply because she uses brass knuckles when she wanted to hurt sanji. Why not just use Haki?
I'm not saying I agree but you could rank them either power wise or just importance to the overall story.
You can say power wise Jinbe then Franky fall in line in terms of power in the strawhats, which I'd agree but match up wise it throws things off because Sanji / Zoro are 1&2 like King / Queen but no current strawhat is comparable to Jack in terms of just 3rd "commander level"
I know we're meming chopper vs queen but seriously. Who's Who also called out Queen maybe dying so you can speculate he's up there with 2nd commanders maybe but kaidos top 3 has remained unchanged for 20 years and it's a crew ruled by how strong you are.
So if Jinbe is Luffys 3rd commander why is he fighting someone below a commander?
That's why I think the matchups aren't organized by power levels. Jinbe & Franky just have ties to Who's Who and Sasaki.
