Alot of ppl believe Mihawk is a crewmate of Shanks. And I don't disagree with this notion. I will explain why?
First let's see Shanks nature a lil bit. Whenever he see a strong guy he asks him to join his group.
Here he asked Buggy to join him.
After Roger's execution we know Shanks and Mihawk clashed
This is where he might have asked him to join him multiple times.
Note after Shanks lost his arm Mihawk never fought with Shanks.
But this incident made me think something. You see Shanks have this hype- Well Balance & Impregnable crew
This was also stressed by Kid who said he lost his arm to Red Hair Pirates. Prolly trying to stir things there.
So how did Mihawk casually enters Shanks hideout/island
Also note whenever a situation like this happened how Yonkos crew reacted:
1) Blackbeard - Moria incident
Shiryu goes offensive mode & cuts Moria.
2) Shanks - WB incident
Marco asks crew to stay behind and Jozu looked pissed. Finally WB told them to stand down.
3) Oden - Roger incident
-Rayleigh & Gabban was ready to attack Oden when Roger used his attack and send Oden flying.
But we don't see this sort of stuff with Red Hair Pirates when Mihawk came
It's like they know Mihawk very well. Not to forget he came with Luffy's poster and said Shanks told him about Luffy. Note: Shanks didn't talked about Luffy with WB. But he talked about him with Mihawk. Strange don't you think?
Some more random stuffs that also kinda strange is:
1)Mihawk don't have a Jolly Roger
2)Mihawk leaving MF after Shanks entered
3)He don't have a crew
4)BB v Shanks (Shanks is 1person short currently)
All these suggest that Mihawk is prolly Shanks Officer and he wanted him to infiltrate Shichibukai ranks to keep an eye on New Pirates as well as WG making a move on (as u know WG asks Shichibukai to help them when they fighting some big shots).
So do u think Mihawk is a crewmate of Shanks or he's just an ally?
