When has any legitimate theme actually panned out though lol. Zoro is tied to dragons and had one thematic dragon clash with Kaido before it didnt matter again lol
Not trying to be an ass, Im genuinely asking because what always gets ignore here is Oda's tendency to make certain enemies relevant to Luffy. For the same reasons Kaido and Kizaru (and Saturn) fought Luffy being the main aggressors of their arc, Shamrock quite literally gives the same aura, not to mention hes the spitting image of Shanks, the person Luffy idolizes.
Why is this being ignored?
