Question:

Since there are going to be canon characters, does this mean that people who want to create characters with Devil Fruit powers will have to create original ones?

Ahhh I see you've caught on. But your correct. Until you kill one of the canon characters and claim their fruit as your own. This might make other players wait before creating a fruit, due to their desire of a canon fruit.
