Let's see how bad Luffy's damaji really is...
Remember the empty promise of Luffy destroying Kaido's body like the destroyed the tree?
Remember how the copium excuse was that he is actually doing that but we simply cant see it because of the scales?
Ignoring the fact that he still cant do anything to dragon scales aside, let's see what don Luffione can really do.
He got eaten by dragon Kaido, again but this time there was no Zoro around to save him so Kaido decided to spit the gum back out since it is bad for digestion. What did Luffy do while he was inside Kaido and why is this important?
Luffy attacked Kaido's insides with aCoC while in his strongest gear - G4 and there were no scales in the way of his damaji.
Read that sentence once again to make sure you understand it.
What was the result of aCoC buffed, G4 powered, scaleless attacks on the insides of Kaido's skull?
Not enough to make Kaido bleed or spit him out - Luffy failed to do what Zoro did with Tatsumaki that wasnt buffed by aCoC.
Take a minute to digest that Luffy's strongest gear with aCoC cant do what Zoro's AoE without aCoC can do.
Now, let's see what Luffy's strongest attack can do - shall we Luffybros?
Luffy's strongest attack, the Supreme Kong Gun couldnt do even as much as the last hit of aCoC-less Kong Gatling did.
It didnt even stop Kaido for a second, he instantly retaliated and almost knocked Luffy out again.
His strongest attack is equal to his weakest attack - close to no damaji whatsoever.
Once again, what I have said was proven right, regardless of how much physical power he puts in, haki remains the same and thus the damaji is also the same. Luffy is the most ineffective hitter in One Piece world, that's why Zoro is the complete opposite of him.
When Luffybros say that Zoro cant rival Luffy, they are absolutely right but they dont know why - Zoro isnt capable of being that bad.
A mesaji for the low damaji bros - As long as you get the bright idea to compete with Zoro, you will always end up disappointed.
