Zoro's next power will put him on the same pedestal as Mihawk.

Conqueror's Haki isnt Zoro's only power-up in One Piece. He must master Asura in the final saga to surpass Mihawk.

Zoro is a strong swordsman, but One Piece has revealed Domi Reversed Dorry to be above his level.

Zoro's King of Hell makes him one of the strongest One Piece characters.
