Let me tell you the sub for this scene is FAR better than the dub! Barto going rapid fire "Ls" before saying Luffy's name is GOLD! The dub doesn't even do that lol
I mean bartos devil fruit power is actually op. Imagine forming a barrier around someone's body or weapon mid attack. That person's body part could either be completely stuck there or even severed if the timing was right. And with awakening he could simply trap people in a barrier prison for as long he could go without sleep. I mean theoretically he could make a barrier around someone's heart or brain and kill them instantly we know he can "tie up" his barriers.
