Appearance
Macro has two large Popeye-like forearms complete with anchor tattoos. He generally wears a necklace of jewels and an open jacket. On his chest is the sun tattoo that symbolizes Macro's being once a part of the Sunny Pirates. Macro is roughly larger than Hatchan in size. Macro is a Gulper Eel Fishman and thus his most distinguishing physical characteristic is his large lower lip and jaw. When he closes his mouth, his lower lip sticks out so prominently that Macro looks like he's always sticking his face up. When he opens his mouth, his lower jaw opens up so wide that the opening his mouth makes is extremely large in comparison to his head. Within his mouth, his upper jaw consists of molars while his lower jaw consists of fangs.

Personality
Compared to his crewmates, Macro is considered the "brains" of the crew. He has a distinct laugh, being "Mohahahaha".

Abilities and Powers
As a Fishman, Macro possesses the abilities unique to his race. He is able to breath underwater and is several times stronger than the average human. However when matched up against the likes of Hatchan, he is relatively weak.

Hatchan's Sea-Floor Stroll
While going out for walk on the sea floor with his men, Macro met up with his old friend, Hatchan. Seeing that a mermaid was with him, Macro decided to trade a treasure map with Hatchan for the mermaid, Keimi. Macro's offer was happily accepted as Macro explained to Hatchan that it would lead the Octopus Fishman to the long sought after legendary Takoyaki sauce. While the map Macro gave was legit, Macro's real intention for Keimi was to sell her off as a slave.

Having acquired the mermaid, Macro and his gang decided to sell her off. They unfortunately didn't get very far when Hatchan suddenly attacked their ship and beat them up. Hatchan apparently came back to beat them because he thought that he was cheated upon by them. The map that they gave him appeared to be a fake to Hatchan since it lead him to a giant squid instead of the sauce he sought after. Macro however explained as he was beat up that they didn't cheat him. While the map did lead to a giant squid, it did indeed lead to the sauce as the sauce was inside the giant squid. With that, Macro and his gang were spared from further injury. Unfortunately, their prized mermaid slave was freed in the midst of Hatchan's attack and decided to follow him.

Having lost their prize, Macro and his gang decided to try to get Keimi back in their clutches and get their revenge against Hatchan.

Alliance with the Flying Fish Riders
Since their initial defeat at the hands of Hatchan, Macro and his crew had been trying to recapture Keimi. They would succeed at capturing her at every attempt but every time they would also be foiled by Hatchan, who had since befriended Keimi and would beat them up. Macro and his crew continued with these scenario until after the thirtieth time, they decided to get some help.

Macro and his crew decided to ally themselves with the Flying Fish Riders. With kidnapping gang's help, they were able to beat up and capture Hatchan. With him in their clutches, Macro not only planned to capture Keimi when she came to rescue him at the Flying Fish Riders' base, but also planned to sell off his former crewmate as a slave since Octopus Fishmen fetched a high price in the slave market. After letting Keimi knew what had happened to her friend via Den Den Mushi, Macro and his crew found out that she was bringing along with her to base the Straw Hat pirates. Amongst the Straw Hats was someone that Macro and his crew's new-found ally, Duval, was looking for. Upon telling Duval of the new turn of the events, he thanked them for their great contribution despite the disrespect Macro's men showed to him.

With a plan to ambush the Straw Hats and Keimi alongside the Flying Fish Riders, Macro and his crew hid deep underwater below the base. Sure enough, their plan to capture Keimi once again work as she dove into their clutches in an attempt to save an imprisoned Hatchan. Unfortunately, she was once again rescued as Luffy grabbed her out of their hands. In midst of the battle between the Straw Hats and the Flying Fish Riders that soon followed, Macro and his crew were once again defeated by Hatchan who was freed by the Straw Hats then. With a punch from one of Hatchan's hands, Macro was sent flying away from the base alongside his men, who themselves were also each punched away at same time by one of Hatchan's other hands.
