Eustass Kid

Eustass "Captain" Kid  is an infamous pirate. He is one of The Eleven Supernovas who are well renowned pirates on Sabaody 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 revealed bounty that is still active, higher than Luffy's bounty by 15,000,000, and the third highest number seen so far in the series, after Donquixote Doflamingo and Gecko Moria. The reason his bounty is so high, is because his crew has caused huge numbers of civilian casualties in the course of their activities.
