I was rereading the One Piece manga today, and found something cool in chapter 56. In Snaji's flashback, when Zeff attacks the ship, we see a guy trying to escape who is holding a devil fruit.
The scan isn't the best quality, but you can easily see he's holding the fruit. But what caught my eye is that he's wearing a crown. Now, I know people besides Wapol can wear crowns, but I think his face could look a bit similiar to Wapol's before eating the fruit (although the face isn't very visible in that scan).
Just a random notion I made, and maybe people have noticed it before, but it would be pretty cool if Oda planned to give us a hint about a future character.
