But being his most important fight, with the most emotion for Zoro =/= being final fight.
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
For this to not be true, their climaxes should simply not even be fights… If for example Chopper’s climax is unrelated to a fight, then it’s fine for whatever his final fight is to be unremarkable filler… But I doubt that will happen
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
See what I mean, even the doctor will have his final fight also coincide with the emotional climax of his character and dream…
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
