Re: Devil Fruit Rarity
I thought this was going to be a discussion about the DF classes and whatnot.
As for your scenario, it would be pretty cool, but I don't see it happening. When thinking about this you need to take into consideration the power structure of the crew. The only person I can see making use of a DF is Usopp, not for himself but feeding it to one of his weapons once the method is revealed by Vega Punk.
Even that is a long shot because Usopp doesn't really need it. I think Oda made his way of thinking regarding DFs and the crew very clear with this arc. Ace's DF will most likely go to a new Nakama and I wager we won't see this kind of situation after that.
