History

Garp takes custody of the newborn Mercer and Ace after Portgas D. Rouge's death. When he realizes that Mercer is unconsciously releasing Observation Haki and may have an abnormal condition, he immediately brings him to Drum Island for Kureha's examination and care. 1 2

Years later, Dragon entrusts his infant son, Monkey D. Luffy, to Garp. Unable to personally raise the child, Garp arranges for Slab and Aying of Foosha Village to care for Luffy while supplying Arthur's medicine in return. He also brings Mercer to Corvo Mountain, where he reveals that Ace and Mercer are the sons of Gol D. Roger and Portgas D. Rouge. 18 19 20

Garp trains Mercer, Ace, and Sabo through survival-oriented exercises and deliberately punishing physical tests. His methods include lake-current trials, launching the boys through the air with his fists, and repeated long-term “devilish” training, but he treats their survival and growth as his responsibility. 41 42 43 150

Although Garp repeatedly urges Mercer to consider the Marines, he accepts Mercer's refusal to be bound by the organization. He protects him politically when possible, conceals or softens incidents involving him, and remains openly proud of his grandson even as Mercer's power and actions increasingly place him at odds with the World Government. 166 167 207 244 274

Appearance

Garp is a burly, middle-aged Marine whose physical presence is intimidating even when he is dressed casually. He is frequently seen in floral short-sleeved shirts, beach shorts, sandals or slippers, and sometimes barefoot. 18 40 151

• Large, fan-like hands suited to his overwhelming punching style. 209
• Usually wears relaxed, informal clothing rather than a strict Marine uniform while off duty. 12 40 151
• Has a powerful build that makes him seem imposing beside Mercer and Eriyi. 151

Personality

Garp is carefree, blunt, and notoriously difficult to keep focused on official duties. He openly treats vacation as a priority, leaves operational matters to Bogard when convenient, and responds to many serious situations with laughter or casual confidence. 12 13 207

Behind his rough humor is a fiercely protective family man. He takes responsibility for Roger's children and Luffy, worries about Mercer's dangerous independence, and values Mercer's promise not to harm innocents even if he eventually becomes a pirate. 19 20 160 244

His mentorship is harsh but purposeful. Garp pushes young trainees into dangerous physical challenges, teaches vigilance through unfair scenarios, and takes clear satisfaction in seeing them survive and improve. 42 44 150
