The only one that will surpass King will be Shiryu since he will face EOW Zoro.
But for now Ben has nothing over King, it's not like Ben will stand like nothing if Zoro stabs him right ?
Ben's entire hype comes only from VC and one page "balanced crew". King is literally said to be a monster and needs adv.coc to be defeated, that's another lvl bro.
See you soon in battledome
