In One Piece, there are numerous characters who can unleash abilities that defy expectations. Nonetheless, in a world where unimaginable feats such as summoning meteors can be actualized, the Straw Hats have always retained a rigid ordering of the top three. This can be seen any time Luffy's crew battles an opponent. During these skirmishes, Zoro has consistently fought the second-strongest opponent after Luffy, while Sanji takes on the third-strongest adversary.
