Eustass Kid

Eustass "Captain" Kid  is an infamous pirate. He is one of eleven well renowned pirates on Shanbody Archipelago whose bounties are higher than 100,000,000 when the Straw Hats arrive in the place. He is named after real life pirate, William Kidd. He owns the highest bounty that is still active, higher than Luffy's bounty by 15,000,000 belli, and the third highest number seen so far in the series. The reason his bounty is so high is because he he did a lot of damage to civilians during his travels as a Pirate.
