Im torn. I dont see him being "outshined" per se, but Zoro deserves his own fight against a YC, so does Sanji.
King and Queen are virtually the perfect matches for this. Queen already having open interest in Sanji points to that encounter happening. Right now Oda definitely wants Zoro do to
something against Kaido, whether thats:
- Fighting Kaido, cuts him, the island crashes to Wano, displacing him and he fights King after.
- Gets knocked away by Kaido early on, fights King, then comes back to hurt Kaido.
- Fights Kaido, King comes up to interfere, he fights King
Just some dumb examples i came up with. Yes Sanji-bros, switch everytime I said King with Queen if you want to believe that's happening
