Zoro's opponents have to be built different, a form of invincibility is a must.
People call it gimmick or one trick pony... No, far from it.
Being strong is simply not enough.
Every future Zoro opponent potentially has a form of invincibility.
Regarding Kizaru, I think it is light multiplication and creating clones to stand up to even Asura.
I have huge expectations for Kizaru and we are almost there.
