User blog comment:Mrgod11234/Can Zoro use haki,And big mam and kadio strength/@comment-1907764-20110725024440

Well i think that Zoro will learn all types of haki.Just like Rayleigh he needs it coz he is Luffy's partner.As for Big Mam and Kaido they are yonko so just think that their power is close to shanks and wb.
