zoro's attempt to hold off the attack was great but, why are people hyping Zoro's attempt to hold an attack than the people who just did the strongest attack in the series?
Because it's the underdog aspect of it.
We know the Yonko are as strong as they are. We've come to expect that they can break islands in half and level countries pretty much. What we don't know is how young pirates can finally break the threshold of being able to handle these Yonko
Zoro was able to hold their attack for a few seconds. He's super hurt sure, but he did it because that's what Zoro does.
Kid took a fucking BM punch to the face and still trumped her with Law and the others.
The villains will always be downplayed eventually in the face of the main protagonists. It always happens in every story, eventually. Especially these 2 since people have the greatest expectations for them behind Blackbeard, Shanks, Mihawk and Akainu
