While I also agree Zoro vs Fujitora is a given, I'm sure you know Zoro vs Kizaru is also a popular prediction because Kizaru kept fighting right hand men in both his appearances. I know about your Luffy vs Kizaru theory, but assuming it does not happen, do you see Zoro fighting both Kizaru and Fujitora at some point or are you more certain of Zoro vs Fujitora solely being it?
Imo, it'll be one or the other only, but that's just me.
I think if anyone is likely to get into a fight with 2 Admirals, then it'll probably be Luffy since that's just his thing. Or Yamato/Jinbe have an opportunity to also fight one.
My current theory is that if Vegapunk is tied to Elbaf, it may feature Kizaru, who might be the next major opponent for Luffy while Zoro/Sanji, etc fight Kuma, Sentoumaru and the SSG. Could be totally wrong that front.
I also believe the Akainu vs Aokiji thing was intentional but also completely staged. They legit fought for 10 days, but I still think it was done to give Aokiji a convincing reason to ally with Blackbeard. I still think he's a marine Admiral. In that front you'd have a pretty interesting lineup for a portion of the engame:
- Akainu vs Luffy, cause obviously
- Zoro vs Fuji, since it "seems" to make the most sense but who knows with him being a swordsman and having pretty broken gravity powers. I can imagine what happens when he fights seriously.
- Sanji vs Ryokugyuu, simply due to their personalities in being womanizers, yet also Ryo not actually eating for some reason. I feel like that's such a direct antithesis to Sanji and it'll be pretty clear as we move in from Wano
- Yamato (or Jinbe?) Vs Aokiji, because in it would be interesting to see how another Ice user goes up against the other, or a water user does the same. This one is pretty random ill admit.
Just my thoughts on that, i don't really subscribe to the whole Kizaru/Elbaf thing just yet. Need to see where he is how Oda ties Vegapunk into the plot
