Right now King is looking like Kaido's strongest subordinate so if the alliance want to take down Kaido then someone will obviously have to take down King. A lot of people think that since he has a sword he must be Zoro's final opponent but in addition to having a sword, King can also fly, uses fire and wears a black suit which makes some people think that Sanji is the one who's gonna fight him. Another option is that neither of them is gonna fight him and he's gonna be taken down by someone else. In my opinion Zoro and Sanji will have to 2v1 him not only because neither of them is strong enough to take him down by themselves but also because of King's design. What do you think?
