Zoro have the Barrier haki(the first step of adv CoA). I don´t know about Kid but it seems like he had a another way to hurt Kaido, so he has only haki.
Luffy has the second step of adv CoA, penetration haki the highest version.
So Kid most like gonna deal damage via hax because he know simple Punch can´t damage Kaido.
I think his devilfruit gonna give him some hax power.
