Taking results as consideration... He is the same as his debut. Taking construction as consideration... He is a garbage Yonko.
Let me say, is not Kaido's fault it is Oda. I will never forget Kaido scream to Law throwing fucking stones to him. Kid fucking suplex him. Kaido should have screamed only to Red Roc, Zoro's and Killers attacks and Law using his DF on him. Nothing else. G4 doesn't use adv armament, so no scream on those attacks too.
Also, why the hell Kaido is changing forms without a reason? Oden beat him in Dragon Form so he came back in human form. Kaido wasn't beat in Human Form to go back to Dragon Form, wasn't beat in Dragon Form to go to Hybrid Form. And after his fight with Luffy he is Human Form again. WTH?
