Like the title says what does mihawk know about zoro? Either information he was told or he himself can infer
For example do you think he knows anything about
- Shimotsuki village
- Zoro’s shimotsuki or roronoa family/lineage
- Zoro looking just like ryuma or ushimaru
- Asura
- Info on wado ichimonjo
- Info on sandai kitetsu
- Info on shusui
- Zoro’s childhood (kuina)
1. Probably? Oda is weird with how he writers character interactions, but you would assume that at some stage during the time skip Mihawk would have asked who trained Zoro/where he learned from in the past
2. Mihawk SHOULD know this due to again spending so much time with Zoro and perhaps connecting the dots but again, Oda.
3. I think Oda will at some point retcon Zoros dad having met Mihawk and used a similar move to the Three Thousand Worlds move Zoro used against him during their first duel. Hence why Mihawk was shown to be slightly shocked by it when he saw it. But beyond that?
Ushmiaru specifically I doubt Mihawk knew about. Though I could see him knowing about Ryuma due to the Black Blade thing though he might not know how Ryuma looked like.
4. I sure as fuck hope at least once during the Time Skip Zoro used that move in some sparring match but you never know. He might have kept that move close to the chest to have at least one ace up his sleeve for his TRUE re-match down the line.
5, 6 and 7. Due to who Mihawk is and the sword he holds, I am of two minds on it. He could know literally every notable sword in existence and be a sword nerd like Tashigi who just has the book on them and their info memorized, or due to having the strongest sword in his possession deem all others irrelevant.
8. Again, Oda seemingly never has people talk, among themselves, ever, but I would assume at least at SOME point during the two years Mihawk and Zoro talked about why exactly Zoro wanted to be the WSS, and his past in general so again yes I think Mihawk knows about Kuina.
