Hatchan (はっちゃん, Hacchan) is an octopus Fishman who is a member of Arlong's pirate crew. He uses a six sword style to fight and like other Fishmen, he is very strong physically. After Arlong is defeated by the Straw Hats and captured by the World Government, Hatchan escapes and opens a floating takoyaki restaurant. He becomes close friends with Camie, a mermaid, and Silvers Rayleigh on the Sabaody Archipelago. He constantly rescues Camie from slave traders because mermaids are very valuable. He later reconciles with the Straw Hats, and provides them with support. He is voiced by Sean Schemmel in the 4Kids English dub.
