Summary
When it comes to the hierarchy within a pirate crew, the captain is always first. They are followed by the first-mate, who, in most cases, is also the right-hand man of the captain. to ensure that the captain’s orders reach the rest of the crew without any problems, some individuals receive the role of chief of staff.
The chief of staff might not be the strongest, but they command the respect of the other crew members. ThroughoutOne Piece, there have been many individuals who have been given the role of chief of staff or staff officer. But which among them holds the most power?

The list includes both chief of staff and staff officers.
6Cabaji
One Of Buggy’s Most Loyal Underlings
Cabaji made his debut in the series in the East Blue Saga as one of Buggy’s main men. He is loyal to Buggy, and he will do everything in his power to make his captain happy. It is worth noting that Buggy comes off as more serious than the rest of the crew, which could have made him the frontrunner to become the chief of staff.
In comparison to the other members of the Buggy Pirates, Cabaji’s physical abilities are rather impressive. He was able to lift Ritchie, a big lion, with one arm. Cabaji fights using a sword, and he has above-average handling skills. Additionally, Cabaji uses carnival tricks to flummox his opponents and take them down when their guard has been lowered.

5Gambia
Barto Club’s Staff Officer
Unlike the other entries, Gambia is not a well-knownOne Piececharacter, but he is surprisingly a strong fighter and a fearless one too. Gambia is a member of the Barto Club Pirates; the crew is also a part of the Straw Hat Grand Fleet. He is a big fan of the Straw Hat Pirates, so to fight under their flag was a dream come true for him.
Gambia has been involved in a notable clash where he and the rest of the crewattacked Shanks' territoryand burned their flag.

4Trebol
Turned Doflamingo Into A Fearsome Pirate
Trebol is one of the main antagonists in the Dressrosa arc. He is the person responsible for turning Doflamingo into a sadistic maniac. Trebol knew that he had to cater to Doflamingo’s ego, and everything else would just fall into place. He was fully aware of the danger that he was about to unleash on the rest of the world.
Naturally, he becameone of Doflamingo’s top executives, looking after the most important affairs. Trebol was also assigned the role of staff officer, which gave him a bit more authority than the rest. Clearly, Doflamingo trusted Trebol, which is why he put him in charge of Sugar’s protection. Furthermore, Trebol was also on the rooftop with Doflamingo, where they fought against Law and Luffy.

3Laffitte
Blackbeard’s Chief Of Staff
Laffitte was one of the originalmembers of the Blackbeard Pirates, meaning he joined the crew before they raided Impel Down. He hails from West Blue, where he served as a police officer, but he committed many heinous crimes for which he was barred from the sea. It is unclear what kind of Devil Fruit Laffitte has, but it could likely be a Zoan-type Devil Fruit. The powers will be potentially covered in the upcoming arcs as the story goes into the endgame.
Unlike most members of the Blackbeard Pirates, Laffitte is rational and doesn’t rush into fights. He also has a great deal of respect for his captain, as evidenced by his decision to threaten Avalo Pizarro. Laffitte also corrected Burgess multiple times, asking him to call Blackbeard admiral instead of captain. It is possible that, due to his refined mannerisms, Laffitte was named the chief of staff of the Blackbeard Pirates.

2Tsuru
Second Only To Sengoku
Tsuru is amongthe oldest serving Marines, as she joined the organization with Garp and Sengoku. In her prime, she was feared by pirates around the world. Even a powerful pirate like Doflamingo considered running away the better alternative to fighting Tsuru. While Tsuru has aged considerably since, it is safe to assume that she is still among the strongest Marines.
When Sengoku was still the Fleet Admiral of the Marines, Tsuru was responsible for relaying orders to others, so she was the second in command. She was known as the Great Staff Officer, which further implied that she was above the rest in terms of authority. It is important to remember that Tsuru was handed the role because of her veteran status.

1Sabo
Dragon’s Second In Command
Sabojoined the Revolutionary Armyunder unusual circumstances. He had set sail in hopes of becoming a pirate, but things took a turn for the worse when a Celestial Dragon shot at his vessel, leaving Sabo in bad condition. Fortunately for him, Dragon was nearby, and he rescued the child from certain death.
Dragon took Sabo with him to the base of the Revolutionaries, which became Sabo’s new home. Sabo trained under the various officers of the Revolutionary Army and improved his combat skills. With time, he became an extraordinary fighter, capable of leading covert operations. Sabo earned the respect of his peers, so nobody questioned Dragon’s decision to name him the chief of staff. Currently, Sabo has a reputation akin to Dragon’s. In fact, people have given him the epithet of the Flame Emperor, which is a testament to his popularity. Given his position, there is no doubt that Sabo will play a crucial role in the Final Saga of One Piece.
