In One Piece, a character representative often does not require anything else but to be a strong crew member to support the team. Although these crew members often receive less recognition compared to the main characters of the story, they still play an important role in the overall design of a character representative and the structure of the crew.
Strong Representative Crews in One Piece Need Distinctive Characters
To become a strong representative character in One Piece, first and foremost, the crew member must have a unique and diverse background. Each individual should possess a personality and distinctive traits that set them apart from all other characters in the roster. Furthermore, these characters must have a well-developed relationship with their peers, building a cohesive crew that grows together. Above all, the characters should also be quite strong and capable of standing firm even against the toughest opponents.
Most importantly, the crew must have a strong relationship with the environment around them. This does not mean that the captain and crew must be close friends in every situation. A representative character can still maintain a tenuous relationship with their crew if the primary theme is accurately portrayed.
Big Mom and Doflamingo Have Remarkable Crews in One Piece

It is worth noting that the crew of Big Mom is one of the most distinctive and diverse in the storyline, often highlighted when discussing remarkable representative crews. With a “human resource” pool that includes Big Mom’s children, each member possesses significant strength and unique personalities. They each have their own abilities and distinct characteristics.
Among the favored characters like Katakuri and Brûlée, or the disliked ones like Perospero and Flampe, the Big Mom crew stands out as one of the most impactful representative crews.

Next, the Donquixote Pirates are also frequently mentioned. Although this crew has a few despised characters, the respect that the members hold for each other is something that few other representative crews in the series possess. With their unique personalities and dislikeable traits, the Donquixote crew, loved and hated alike, stands as one of the most prominent representative crews that the Straw Hat Pirates have faced.
Cross Guild is the Most Notorious Representative Crew in One Piece

However, the most infamous representative crew in the series must be Buggy and the Cross Guild. Initially, Buggy, with his charismatic leadership style, created a notable relationship between himself and his “underlings,” Mihawk and Crocodile.
The Cross Guild has brought together numerous remarkable characters that fans admire and respect throughout the entire series, including members from Crocodile and Buggy’s former crews. The mere presence of Mihawk and Crocodile in this crew also elevates Cross Guild to the top tier of representative crews. With characters like Daz Bones, Galdino, and Alvida also part of this notorious group, this crew has considerable potential within the series.
While these three crews are some of the most powerful representatives in One Piece, ultimately, the preference for any representative crew depends on personal taste. Some character dynamics of each representative crew are more favored by certain fans than others. In conclusion, nearly all significant representative crews in One Piece have been built with distinctive characteristics.
