Luffy was physically superior or equal to kat, his only problem was FS. Kaido massively outstats him in strength and speed and even durability. The same thing with Big mom. She was punting him in her amnesiac childlike state 6 days prior for gods sake. Why would you think luffy can now hang with them is beyond me, its shit writting if it happens. Basically fairy tail level. There is a reason its an alliance to take down a yonko. Stop fucking downplaying them. And luffy is not ready to solo a top tier yet.
How is it fairy tail level if Luffy had
two whole weeks of training before taking on Kaido for the second time. This is literally how almost every single fight based story goes down.
- protagonist faces antagonist and loses badly
- protagonist works hard to become stronger and overcome weakness
- protagonist faces antagonist again and wins
Kaido massively outclassed him
two weeks ago. Since then Luffy has increased
- his base strength and physical abilities
- his CoO
- his CoA
- his mastery over G4
How would it be "fairy tail writing" for Luffy to be able to match him after all he went through? And mind you I never said Luffy would win without help. Luffy has gotten help in every single fight post-skip and I'm sure he'll get help again with Kaido. However what I do believe is that Luffy vs Kaido will be, for the most part, a 1v1. With any help being minimal; see: Luffy vs Doffy, Luffy vs Cracker, and Luffy vs katakuri.
But the very fact that Oda has stated in interviews that Luffy will defeat Kaido indicates that it will be mainly Luffy, and not anyone else, who will beat Kaido.
