This is a more specific thread just for Zoro and no one else.
Is Zoro already utilizing hakki in his attacks?
Did he kill/ defeat Mihawk during the 2 year time skip?
How did he get that scar over his left eye/ Can he open his left eye?
Just some questions to get it started off. yes i do believe zoro has hakki, and if he doesn't have it know its only going to be a matter of time before he does.
Why do i think zoro has hakki
1. He trained with Mihawk for 2 years and he is known as the worlds strongest swordsman.(speculaters - well mihawk was never shown using haki)
2. Vista has hakki and he's a swordsman and is nowhere near Mihawks strength.
I believe Zoro even used hakki in the past when he fought Daz Bonez in Alabasta, When he used Asura against Kakaku, and also when he sent Ryuma on fire during the Thriller Bark Arc.
