As we know, there is no pig devil fruit.
But look at cover of chapter 10
The cover page shows a pig wearing that Japanese bandit scarf thing and it has a devil fruit pattern on it. Do you think, this is some sort of foreshadowing?
If so, it would indeed be quite unusual, as up to this point, despite more than 20 years having passed, there is no record of a pig devil fruit. Maybe someone from gorosei?
One of them possesses tusks resembling those of a boar.
This theory make sense, given that I believe the Gorosei and other significant characters have fruits associated with the Chinese zodiac.
