If you can beat Kizaru in a fight and get to that level, you can hurt Kaido.
I don't think so.
Many people most notably Nik.
And the same with mine so.....
No that's not how it works. You need basic haki to hit a logia
You need ryou in terms of haki to hurt Kaido
And I'm not talking about just hurting kaido
I'm talking about surpassing what oden did to him to a stronger kaido.
Thats far beyond anything sanji will be able to do.
No kizaru always matches up with right hands Ray Benn Marco etc
He eve was the one who was about to kill zoro in sabaody.
Zoro will fight him.
