Re: Devil Fruit Rarity
There is a very slim chance of that possibly happening but if it does I can also see Usopp using it to upgrade his weapon as mentioned. I can also see maybe Chopper and Robin studying it to understand its properties more, especially Chopper seeing as he's the first person mentioned to have fiddled around with his DF abilities with science.
