It is… Zoro’s most important and emotional fight will of course be Zoro’s final fight
And that true for every character
Luffy’s most emotional and important fight will also be his final fight
same for Sanji, Robin, Chopper, Usopp, Franky, Jimbei, Brook, all of them
this will be the set up for every character… And the only way this doesn’t happen is if Oda decides that something about the character’s emotional and narrative arc has nothing to do with combat, that’s the only time Oda will separate “final fight” from “narrative conclusion”
And unfortunately for you, Zoro is the only character on the crew where his whole deal is combat… Oda cannot make Zoro’s final fight not be the climactic fight of Zoro’s entire arc… that’s like as basic as having Luffy’s final fight be the fight where Luffy saves the world… this is simply what these characters whole stories have been leading up to
Again, it's impossible for Zoro to fight Mihawk last since it would have to be the last fight of the series. No bounty increase for Zoro. No WSS on Zoro's bounty. No WSS introduction for Zoro in the final war. And no keeping promise for Luffy about not making Pirate King look bad by not being WSS on his crew.
Oda made Mihawk
active now and
go for the One Piece because he will have Zoro beat Mihawk at the same time as Luffy becomes Pirate King.
Cross Guild exists
SOLELY to make Zoro vs Mihawk happen for the duel for the one piece
before fighting marines/WG
for example It’s not a coincidence that Chopper wants to cure all diseases, and his final opponent is a guy who can make any disease… its very likely that somehow someway, during this Doc Q fight, that’s when chopper will learn how to cure any disease
I for example don't think it's possible for Chopper and Doc Q to fight or even be final fight
1. Blackbeard and his crew are too weak to be final fights
2. Chopper can't fight AND cure disease. It took Chopper a lot of time just to create anti-bodies for Queen's ice oni, and he only created so fast because Queen gave antidote.
How the hell Doc Q vs Chopper is possible if Chopper needs lots of time just to cure 1 disease?
Doc Q is just gonna stand around and wait for Chopper to make the cure?
Brook vs Doc Q is far more likely since Brook will probably be immune to Doc Q's diseases and both of them carry the Grim Reaper theme.
