Okay this contains spoilers from Skypia that are ahead of the current KF episode. If you haven't seen past the current KF episode then DO NOT READ ANY FURTHER!
I was thinking. I know Enel is basically lightning… and rubber doesn't conduct electricity, but should Luffy really have been able to hit him that easily? especially with that golden ball because that DOES conduct electricity. Everything else just goes though Enel, bullets, wood, swords and the like. And it's not like Enel has to concentrate to have this happen, it just does. It's like Crocodile and his sand thingy. So how is Luffy really able to hit him?... not trying to be a pain but it's just something I was thinking of :unsure:
