So I'm pretty sure there's gonna be a Vegapunk arc and the antagonists will probably Sentamaru, Kuma and possibly Kizaru(since he had his lasers installed). So who do you thing will fight Kuma (if he is an antagonist)? Zoro, Luffy or even Franky.
I think that Luffy will fight Sentamaru halfway through the arc or as soon as they get their, then Kuma's history will be revealed ETC and then the final fight for the arc (with which Kizaru could possibly be involved in).
