Koby

Seiyuu: Mika Doi

Koby (コビー Kobī), a small, timid, bespectacled boy, is the first person Luffy meets on his haphazard journey. Koby had intended to board a ship for a fishing trip one day, but by accident, instead found himself amid the dangerous crew of Lady Alvida. To stay alive, he 'volunteered' to become a lowly cabin boy for this band of pirates, but fostered a desire to escape one day, and even join the Marines. His fear of Alvida prevented him from leaving, but Luffy's arrival and triumph over the 'ugly old hag' (as Koby summoned the courage to call her) finally brought him hope. After helping Luffy and Zoro free a nearby Naval base from the grip of the tyrannical Captain Morgan, Koby is admitted to join the Marines as a Chore Boy (雑用 Zatsuyō), alongside the Captain's disgraced son Helmeppo.

In his and Helmeppo's title page mini-arc, the two become unwillingly involved in an escape attempt by Morgan the prisoner (Morgan takes his son hostage and steals a ship). Though Morgan escapes, the bravery shown by the two earns them the respect of their superiors, and the attention of Vice-Admiral Garp. He and Helmeppo are currently serving under the Vice-Admiral, at the same base that is apparently Captain Hina's home port.

His dream is to become an officer so he catch criminals such as Alvida.
