King fking Luffy up has nothing to do with King vs Kaido bcs Kaido is a different character with different stats than Luffy.
Even if you believe that silliness that Luffy will defeat Kaido, what does Luffy vs Kaido has to do with Luffy vs King?
I dont believe Zoro is stronger than Luffy, I know that Zoro is stronger than Luffy, dont mistake those two.
