Jesus...
Read the fucking real manga, not the edited version were Zoro is all that matters dude ! He and Killer were panting like crazis on the roof, while the captains were all fine. Yeah, he tanked one super atatck... for two seconds and almost died because of it. And he scarred Kaido, thanks to Oden's haki still being in Enma/Enma being an abnormal blade.
I swear, you Zoro fanatics are the main reason I can't stand discussing OP anymore. You understand shit and spout the worst bullshit ever and refute evidence when it's presented.
Do you notice the "huff" happening only near Zoro and Killer or even in their sentences ? The little ball of breath near Zoro ? He and Killer, as Vice-Captains, are far weaker than their Captains. That's why he's dealing with King - and it isn't a no match yet, in spite of his broken power-up sword - while the Captains are dealing with the Emperors.
Luffy >>> Zoro > Sanji
As simple as that, with ample evidence since at the very least Enies Lobby.
