Shichibukai (Zeon1)

The Oka Shichibukai (王下七武海) are a group of pirates-turned-privateers employed by the World Government.

Founded in order to maintain a "balance of power" between the three great factions, they are each pirates who have made quite a name for themselves in the Zeonverse. As Shichibukai, they gain nigh-total access to the Government's various resources and are no longer pursued by the Marines, in exchange for being required to follow every command by a proper member of the Navy. Their reputation and strength are often used to keep other pirates in check.

They play a major role within the events of Proud Line.
