In the history of the Shonen genre, duos have always been infectiously popular, who would join forces to take down a common enemy. Usually, these duos share a common objective, but mostly these pairs are just great friends. While a group of three friends is legendary, mangakas typically avoid it because it disrupts the balance of the story.

This felt true until One Piece introduced the Monster Trio, which consisted of Monkey D. Luffy, Roronoa Zoro, and Vinsmoke Sanji, who form the core of the Straw Hat Pirates. With the mighty responsibility of taking down the strongest enemies in every arc of the series, thus becoming irresistibly loved among the fandom.

However, fans should not go overboard in loving the trio because these three names follow the most disgusting habit that one should reconsider thinking about if they do not want to be kicked out of their social circle.
