Background / History

According to Cook, Ares was once a gifted doctor who was expelled from his homeland after being blamed for giving its prince the wrong medicine. Cook believed Ares had been framed by a jealous teacher who switched the medicine and took over the prince’s treatment. Disowned and stripped of his surname, Ares turned to toxicology. 9

Five years later, he released a contagious plague in his former country. The disease infected the entire nation within a month, killed more than one million people, and could not be cured despite World Government quarantine efforts. Ares was imprisoned by the Marines for twenty years until an earthquake flooded the prison; Cook rescued him and left him on Thousand Lake Island. 9

On Thousand Lake Island, Ares used his knowledge of toxins to treat victims of venomous insect bites. His success made him locally famous, but it also attracted the Bloodhand Pirates, who kidnapped him after he refused to join them. 11

When Blood Hand Brian appeared to kill him with a spear, Ares survived by dodging the strike and bursting a concealed blood pack to fake his death. After Rogge’s group destroyed the Bloodhand Pirates, Cook invited him to become their ship’s doctor. Ares accepted, recognizing the danger of refusing the overwhelmingly powerful crew. 15 16

Appearance

Ares is a long-haired, scruffy-bearded man whose dangerous hands are normally hidden beneath gloves. 15 16

• His bare hands are purplish-black from poison corrosion. 16
• His fingernails are black. 16
• He wears long gloves reaching to his elbows to prevent accidental poisoning. 16

Personality

Ares is practical, cautious, and visibly more anxious in combat situations than the Asura Pirates’ frontline fighters. His fear is tied in part to guilt over the plague he released; he insists that he did not intend to kill anyone, while Rogge forces him to confront responsibility for the disaster. 20 21

Despite initially joining from self-preservation, he quickly adopts the crew’s shared-fate outlook. He rejects the idea that only a doctor’s life matters aboard a ship, arguing that every crewmate is necessary for the others’ survival. 17

Cook maintains that Ares is personally kind despite his history, creating a contrast between his gentle medical role and his capacity for mass destruction through disease. 9
