Arlong

Arlong the Saw is a sawshark fish-man. He was the captain of the all fish-man crew (excluding Nami), the Arlong Pirates, a former member of the Sun Pirates, and the older half-brother of Madam Shyarly. He is also a major inspirational figure for the New Fish-Man Pirates.

Following the death of his former captain, Fisher Tiger, Arlong was captured and sent to Impel Down, but received a pardon thanks to his comrade Jinbe becoming one of the Seven Warlords of the Sea. Once freed, Arlong set his sights on conquering the East Blue, settling himself on the Conomi Islands alongside his crew and racketeering the local population. He is also the man responsible for killing Bell-mère, Nami and Nojiko's foster mother. Arlong then had Nami become his subordinate, taking advantage of her cartography skills to one day conquer all of the Blue Sea.

Arlong had the highest bounty in the East Blue before being defeated by Monkey D. Luffy. Due to his actions and role, he is the main antagonist of the Arlong Park Arc.

Arlong is a large, muscular, light blue saw-shark fish-man whose most distinctive trait is his saw-shaped nose. He has long, black hair reaching down to his shoulders and with a widow's peak. On his head, he wears a brown ushanka. He has a fin on his nape, surrounded by his hair, and his gills are located on both sides of his neck. His Sun Pirates tattoo is on the left side of his chest, while his own Jolly Roger is on his left forearm. Other notable features include thin, fierce light-blue eyes and a long, angular jaw. Arlong's attire is composed of fashionable, light clothes, reflecting his rich status as well as his background as a thug. He wears a short-sleeved, unbuttoned yellow cabana shirt decorated by many black lightning-like spots, Bermuda shorts which are brown in the manga and green in the anime, a purple sash around the waist, and simple sandals. He also sports a lot of jewels: he has a golden chain bracelet around his left wrist and two golden bracelets around each ankle, with straw-like decorations hanging from them. On his hands are what appear to be rings, decorated by colorful gems. However, according to Oda in response to a fan about these rings, these are piercings that go straight through Arlong's fingers, as his hands are webbed and are incapable of wearing rings. As a member of the Sun Pirates, he wore an A-shirt, sometimes changed to a sleeveless, unbuttoned shirt decorated by flower-like motifs. He also wore a bowler hat and loose pants reaching down below his knees, first a light-colored pair with a line of similarly light spots on each leg's inner part, and later a similar pair, but darker in color and with spots on both sides of the legs. He already sported the straw decorations around his ankles and the sandals, and also donned a pair of large circular earrings.

Arlong considers humans to be inferior beings and is very cruel to them. He thinks nothing of killing a town full of humans, although he seems to prefer controlling people with money and deals. Because of his love for money, he is known to be very cheap, as Hyouzou refused to join his crew because Arlong refused to compensate him for his service. He does not seem frightened by anything, and his fish-man strength made him extremely confident that he and his crew were virtually invincible. After Marine Captain Nezumi rejected his invitation for a drink out of fear of being seen in Arlong Park, Arlong simply offered to kill anyone who dared report him. He has an eye for spotting exploitable talent that he can use for his ambitions and is an excellent planner. He spent eight years using Nami and her maps to plan his conquest of the East Blue. Nevertheless, any promise about money he makes, he keeps. The best example is when his crew urged him to keep Nami even if she gathered Beli 100,000,000. However, even though Arlong states he cannot go back on his word, he has no qualms about exploiting loopholes in his deals to get his way unfairly. He said he would free Nami's village if she brought him Beli 100,000,000 but was more than willing to cheat her by having corrupt Marines confiscate her money to keep her in his services. He gets angry rather easily, as he nearly went on a rampage after being attacked by Usopp and had to be dragged back to his base by his crew to prevent him from destroying Cocoyasi Village. During his fight with Luffy, the boy's constant fighting back made Arlong deeply angry. Arlong had expected Luffy to die quickly, but his anger made him reckless and destructive, causing him to seriously damage his own headquarters and map collection while attacking Luffy.

He has been ill-tempered since his younger years. However, he was not always entirely brutal. During a battle with the Marines, Arlong told Jinbe to leave the unconscious Marines alone. However, he became more arrogant over time, to the point that he completely lost any sympathy for humans. The circumstances behind Fisher Tiger's death led to his hatred of the human race greatly intensifying. He also failed to understand Tiger's reason for letting humans that they attacked live. As a result, when Arlong led his own crew and committed murder, humans came to view him as a monster. In the end, he enslaved humans just as the humans once enslaved many fish-men. Though his opinions and ideals were extreme, he displayed a high level of brotherhood with his crew and even towards Nami despite the divide between their species. Arlong looked after his subordinates, and even though he betrayed Nami, he did so because he did not want to lose her talent. On top of this, in the final moments of the battle with Luffy, he stated that Nami was his crewmate and would be forever, and while he never displayed any regard for her as a friend, he was prepared to fight to keep her in the crew. If humans insulted their group, Arlong would become enraged, resulting in officers attempting to keep his temper under control. When weaker members of his crew were hurt, Arlong would seek revenge on those responsible. He cared for his crew to a level that when Luffy used one of them as a shield, Arlong became extremely angry. Ironically, Arlong is a hypocrite, having accused Koala of being raised to look down on fish-men and think of humans as better than everyone else, when Arlong looked down on humans and preached fish-men superiority himself, making him no better than the humans. According to Hatchan, despite his hatred of humanity, Arlong would never harm his fellow fish-men no matter the circumstance.

He cares for his own crew (shown when he apologizes for accidentally biting them and becoming enraged at Luffy for using one as a fish-man shield), while many of his crew share his ideals. They would call him "Arlong-san" while Arlong would call his crew his "brethren". He can be very angry when someone hurts his crew, rather similarly to Luffy's feelings towards his crew. However, this is exclusive to fish-men.
