Fallen_Crown
well author's opinion is authors so he can write his fanfic as he see fit. but I see one piece world from more humane perspective otherwise devil fruit won't be that cool. yeah many characters can destroy island not islands but they need to put an effort in it. they won't do it casually like some monkeys or a racist lizard. otherwise ruler of wg won't need ancient weapons for it. ultimately one piece is story of pirates searching for treasures so...thank you .
