One of the most interesting relationships in One Piece’s Straw Hat Crew has always been the rivalry shared between Sanji and Zoro. Although many of the other Straw Hats live in relative harmony, Sanji and Zoro seem to be the only duo in the crew that doesn't actively get along. Between constant bickering, fighting to see who’s stronger, and an endless stream of insults that they both lob at each other, Sanji and Zoro, at least at first glance, seem to hate one another in One Piece.
