One Piece OC Name Generator

A One Piece OC name should feel like it could appear on a wanted poster next to Luffy's without looking out of place. Eiichiro Oda names characters using a few reliable sources: real pirates and privateers (Roronoa from l'Olonnais, Eustass Kid from William Kidd, Bartholomew Kuma from Bartholomew Roberts, Capone Bege from Al Capone), foods and drinks (Nami's Cocoyasi, Sanji's Baratie, the entire Charlotte family of desserts), Japanese historical names for Wano and its samurai (Kozuki, Shimotsuki, Kurozumi), colors and animals for Marine admirals (Akainu, Aokiji, Kizaru), and single blunt words for many minor pirates (Killer, Bepo, Buggy).

The list above works through those sources without touching canon characters. There are Western-flavored pirate names built on twisted real-pirate surnames, Wano-style names in family-name-first order, new members of established families such as the Charlottes, Vinsmokes, and Donquixotes, characters carrying the D. initial for writers who want to play with the Will of D., Marine codenames in the color-animal pattern, and one-word names for the crew's cook, sniper, or helmsman.

When you pick one, decide the character's sea of origin, crew role, and whether they eat a Devil Fruit — those three facts drive the epithet the World Government will print above the bounty.
