Hatchan

Seiyuu: Toshiyuki Morikawa

Hatchan (はっちゃん, Hacchan, called "Hachi" by most characters) is an octopus fish-man. Hatchan is not very bright but a skilled swordsman, using rokutōryū ("six sword style"). He fights with Zoro during the Arlong arc. Despite Zoro suffering a fever and severe blood loss from his unhealed wounds (which he got eariler fighting Mihawk), Hatchan is still defeated by him. Later in the manga (in a title page arc that was never animated), Hatchan goes on many adventures, which end up in him opening a floating takoyaki restaurant.

Hatchan's name is quite strange. In the Japanese language, chan is a diminutive suffix, added to the end of someone's name, giving it the meaning of "cute" or "little". However, Hatchan insists that his name is Hatchan and that Hachi is just a nickname. When questioned on this, Oda replied that the chan is the same as the last name of "Chan" common in Chinese, rather than the suffix -chan.
