So, we know that Kidd is somewhat cruel and has more bounty than luffy, do you guys think that he might be like the main rival of luffy for the remaining of the series or will he just be a stepping stone for him?
I mean i know there are already a bunch of people chasing the strawhats:
Buggy Pirates
Smoker
Black Beard (not sure if he is still aiming for his head but wasn't he only interested in luffy to get famous? And now that he has beaten Ace I don't think he still has to)
but none of them can really fit the description of an arch-rival, something that can be compared to WB and Gold Roger. And I'm not sure if there is gonna be one but after they cross the new world it seems fit for them to have one.
oh and here is why I think none of them can be luffy's rival:
Buggy: Not necessarily weak (he got outsmarted and outran during the encounter), but his image or fame isn't really as good as luffy.
Smoker: He is more like Garp than WB for Gold Roger
Black Beard: Already a shichibukai (although at first his crew have counterparts from the sh.)
