I kinda like King and I still have hope he'll shine when Oda decides to give him more focus but for now, he hasn't done much. If King fights Zoro, that fight'll show us more of King. If he doesn't fight Zoro and just continues against Marco, we still might learn more about the guy. I'm disappointed but not to a crazy extent and I haven't given up on the guy yet. I'm not worried about King's strength but mainly his character and I hope we see more of it.
