Seven Warlords of the Sea
The Seven Warlords of the Sea (七武海, Shichibukai), the full title being The Royal Seven Warlords of the Sea (王下七武海, Ōka Shichibukai), was a group of seven powerful pirates who are granted legal leniency to do as they please by the World Government and have their bounties void in exchange for a fraction of their loot and defeating weaker pirates, who deride them for selling out. The Seven Warlords are loosely based on the European privateers, government-endorsed pirates considered heroes in their homeland and pillagers in others.
