Zoro used a single attack on Lucci to defeat him. Even if people want to cope and say they fought for a while, Zoro clearly can one shot Lucci when he so chooses!
Because unless yo uwant to claim Oda of panneld Asura? Zoro has Asura in his arsenal to use whenver he likes. Anybody coping with "muh 6 months" off-pannel bullshit has no argument against the fact that Zoro can just tapped Lucci without even using Koh! Much less, Asura!
There are levels to this shit!
