Denjiro got so much hype for easily blocking a 720 pound canon
I'm sure Zoro will try to take on King all by himself, but will he be able to prevail? I'm not so sure, maybe he really needs help from a really powerful person like Denjiro Oda is also hyping him up so much
Zoro doesnt lose his fights. He's not like Luffy who fights the same guy for multiple rounds and then wins. Zoro fights Daz bones who he cannot even injure the same way luffy fights Crocodile who he also canot even injure but the difference is Oda makes sure Zoro wins there and then. No multiple rounds.
If Zoro literally cannot beat king by himself then Oda just won't make him fight king. Simple as that.
And all the head canons in the world will explode.
