None of those. Asura slash has made Kaido show signs of weakening for the first time ever by showing exhaustion, trembling, huffing and having trouble standing on his feet. I dont need to point out that it is the single greatest hit that Kaido ever received, tied with Oden's, since we all know that, including you.
He didnt defeat Moriah on his own. The majority of damage came from Nightmare mode which is thanks to Moriah's power.
Moriah himself lost his mind the moment he used Shadow Asgard, manga already confirmed that and it was the fall of the tower than KOed him, not Luffy. Literal facts which you keep denying.
Except Rokuogan isnt blunt damage. Try again, you cant be this bad at power scaling.
My idol is coming back for Kaido to steal away the only thing Luffy had going for him in this arc.
