Duo win High end of Mid Diff but lol at King being able to beat Kata.
King has been irrelevant in Wano despite being First Mate. He will need to display multiple things to be put equal to Kata let alone be above Kata. If King is indeed Zoro's opponent (Explains why Z fans are wanking the fuck out of him), he won't be stronger than Katakuri. Oda won't give Luffy opponents that are weaker than Zoro's opponent especially post time skip. Kata was and is The Man in his crew. I'm a Linlin fan but I wouldn't even doubt that the crew Respects Kata more than they respect Linlin. Now, he is no where near as strong as she is, they follow Linlin because They Fear Her, and she is their Mother. Kata has the love and admiration of his entire family. He literally carries the BM pirates on his back.
King has displayed no such relevance in his own crew. He is just another commander. Kata is closer to a Beckman than he is to a King. King will need to show an advanced form of Haki, Awakening, and COC to be on Kata's level. Even then, with how little relevance he has gotten despite being years into Wano, it's unlikely he is on kata's level.
