User blog comment:Sentomaru/Are Devil Fruits too common?/@comment-5503056-20121024173628

Well, the reason might be because in the early episodes of One Piece everything happend in East Blue, also known as the weak sea. Arlong was the pirate with the highest bounty before Luffy beat him. Only 20 millions >.<.

I don't think they are too common. Considering how many characters we've met, the amount of Devils Fruits are very low. I think they are just rare enough, but that's my opinion.

As the journey goes on they meet more powerful peoples and crews so I think it is just natural that we see more of them now than we did in early OP
