Luffy’s obviously a massive Roger parallel. But also Shanks
Zoro and Rayleigh are... okay, they’ve got some things in common but it’s mostly just that they are both the right hand men of the Pirate King. It’s certainly no Luffy/Roger both sharing some specific dream.
Sanji and Jinbei are probably Scopper and the fishman that’s name I can’t remember in strength at least. but Scopper and the fishman just haven’t been characterised nearly enough
Oden’s a weird amalgamation of Luffy and Zoro with the purpose of Robin, who also doesn’t fit in since he was a Whitebeard Pirate as well. Yamato?
You can stretch and get Usopp and Buggy in since they have both managed to fluke their way to gaining an army (Dressrosa and Impel Down)
Chopper and Crocus just don’t have anything in common other than being doctors, and Crocus is actually more linked to Brook
There’s nothing for Nami that we know about. Unless you wanna go a shipping route and try and argue Nami = Rogue, and shipping just isn’t my thing and I think that particular argument is rubbish regardless
One of the actual strongest parallels, second only to Luffy and Roger, is that Franky is a Tom that decided to sail with the crew.
