[Discussion] There is such a thing as Devil Fruit Mastery

[shri3kbat]

No man JUST NO!!!!! ace know very well that if he fight akainu he will lose, but he has no choice, because luffy just sit there while akainu go after him he has to save luffy somehow and that's the only way, he never think that just because he was logia type akainu punch will have no effect for him, he knew what will happen and he still do that:shrug:

Didn't Ace attack Akainu just because he provoked him ? They were just gonna go and Akainu taunted Ace into attacking him and killed him.
And yes, of course you can train your devil fruit ability.
