Fascinating that they put Shanks where he is in that opening. Every other character is in wano or was featured/associated with the storyline of it, except Shanks.
With the Anime often spoiling manga events, I'm curious if Shanks also shows up this arc, potentially to deter CP-0/Marines, then reveal his true motives to Luffy.
This also kind of aligns with the fact that Luffy hasn't met Shanks yet and Oda alluded to it potentially happening before Film Red
Also a year late but Oda also claimed Shanks will "make his move" soon too. Whatever that means
