According to the One Piece wikia's Enel page, Enel's power won't work against luffyLuffy because he is a rubber-man. But at some point, I'm confused from this fact since lighting that strikes at 1 Million VoltzVolts would burn out anything, even rubber. Also, he had meltmelted gold and it was placed on luffy'sLuffy's hand.
So my question is, is there any logical reason why is it that luffyLuffy doesn't feel any hurt when Enel strikes him?? I will not include what episodes this happen.
