It seems like it is not KG, but KKG adv CoC version xD.
This would made it even more insane if Kaido casually tanked it...
And yeah Kaido also would tank the other Over Kong Gun.
People should realise that Kaido is about to tank far stronger attacks as OKG later when Luffy awake his df.
Kaido legit had the upperhand in this battle, he easily counter Luffy snakeman with his own highspeed+future sight, he easily took down Boundman, it was clear the Drunken Hybrid Kaido was winning against Adv CoC Boundman...
