This is why I strongly believe Zoro vs Kaido is happening;
- This chapter confirms Queen vs Sanji. Queen was holding both Sanji's and Zoro's bounty posters, but he was more interested in Sanji.
- Similar to Luffy, Zoro lost a lot of energy fighting gifters and chasing Apoo. Both Zoro and Luffy took a hit from Apoo. This corresponds to Kaido vs the Scabbards and how he lost a lot of energy and took some damages from them. Oda wants to give them a fair fight.
- You can't fight a Calamity if you are not fresh. That's why Jinbei, Sanji, and Marco are more qualified to fight Calamities than Zoro. Unlike Zoro and Luffy, they haven't lost any energy.
- If Zoro fights King and wins it would make him look like a monster and stronger than Luffy which doesn't make any sense. He fought an army of 500 gifters, took a huge hit from Apoo, clashes with X-drake, clashes with Apoo, and chases him then goes 1vs1 against King and defeats him? That's an enormous feat.
- Without mentioning Enma, Ryuma, and all the scary foreshadowings of Zoro vs Kaido.
You can keep denying ZKK but I promise you that it will happen.
