mention 10 attacks stronger than it
The attacks that can actually leave a mark on Kaido - Oden's Togen Totsuga and Zoro's DeadMan's Game at the minimum.
Plenty of other upper echelon attacks from Zoro can do it too. Especially after aCoC buff.
Island buster from two top tiers - Hakai. Mihawk's upper echelon attack(s), Shanks' upper echelon attack(s).
Akainu's upper echelon, Rayleigh's, Kizaru's, Shiryu's, Fujitora's high-end attacks...
They are all stronger than this punch. Especially if we take someone other than Kaido as a target.
All this does is pushes Kaido around, just a lot more than before. We know that pushing Kaido around achieves nothing.
You just got the illusion that it is powerful because Kaido is exhausted...
I would give it credit and perhaps call it the strongest punch but that's it. Lethal players arent playing the punching/pushing game.
