Katakuri loses to WCI Luffy. WCI Luffy gets one shotted by drunk Kaido. Luffy needs 3 weeks Haki training, still doesn't do shit. Zoro scars and bypasses Kaido scales. Luffy gets another power up, AdCoC. Zoro fights King, who's scales he can't easily bypass due to his gimmick. One shots him when he gets AdCoC.
Somehow a YC1 from a previous arc is stronger than current MCs opponents. A Luffy and Zoro that needed 1 and 2 powerups to beat their current opponents.
Katakuri is trash, just like his mother and you mofos just gotta deal with that 💀
