if you think buggy means admirals > yonko explain this. lets start early and then build to admirals
survives Monkey D. Dragon's lightning attacks
Escapes sea stone net and survives Aokiji's ice. Offscreened both times because this is so easy for him.
The only person who tried to protect Luffy from Akainu and didn't take damage. Ace couldn't do this. Jimbei couldn't do this. Buggy just dodges the admiral with no effort.
Buggy can even dodge Kizaru. Kizaru can shoot a key to break it in half while its moving from 100 meters away but he cant hit Buggy. How can Buggy make Yonkos look bad vs Admirals, when Buggy already made admirals look bad? They can't touch him, and they cant hurt him if they do touch him because Buggy will just offscreen recover.
In fact with this portrayal we should talk about Buggy making the Yonko look strong again after Kaido and Big Mom disappointed so hard
