The student looked upon the master and asked: "Shishou why do we call Zoro the Grandmaster?" The master turned around to face the student leveling a solemn stare and speaking with the gravitas befitting his position as the 4th master of the Holy Temple: "He just is. Such is the way of the world, a mystery beyond the likes of us mere mortals to comprehend".
I hear you sayin Zoro post EL mid diff Kaku with Ashura. You mean using Strongest move to finish off an opponent is mid diff? So Luffy Mid diff Doffy if he striaght up uses KKG on Doffy? and Extreme diff otherwise? Or there more to it?
Does Katakuri have Ryou? Katakuri isn't using the advanced form always. He clashed with Luffy multiple time, until he decided to level up. With that, he broke through Luffy's Haki. Well, it would make sense that a first mate is able to utilize Ryou. Cracker also seemed to have stronger Haki than Luffy, however it wasn't displayed as such that he could straight out break through Luffy's Haki. @Sentinel@playa4321
Post Wano Zoro's power level seems to have a pretty large room for variance. Giving the information we have right now, it seems likely that Zoro will do one or more combination of the following:
* Defeat King.
* Replicate/Surpass Oden's feat of scarring Kaido.
* Beat Kyoshiro.
Now that we know Oden was able to permanently scar Kaido (and the only one to do so), it seems obvious that the slash Mihawk sent at WB was far from his strongest slash. Especially as Mihawk is a superior swordsman to Oden.
I may have once said that Zoro could react to Snakeman (@HeroesNZ do you remember this?) based off his feats of reacting to Kuma's pad canons preskip. Suffice it to say that I no longer believe this. WCI Snakeman likely ragdolls DR Zoro. The difficulty depends on Zoro's endurance.
