Bartholomew Kuma (バーソロミュー・くま, Bāsoromyū Kuma) is a Shichibukai and former Revolutionary with a bounty of 296,000,000. He was once feared as an extremely vicious pirate, earning himself the title "Tyrant". He is a type of cyborgcalled "Pacifista" (パシフィスタ, Pashifisuta) developed by Dr.Vegapunk. Once Vegapunk finished his modifications on Kuma, the Shichibukai was converted into the first complete Pacifista cyborg with the serial PX-0, figuratively dying in the process. He was a very influential character during the Whitebeard War Saga, setting the stage for Luffy's appearance in Amazon Lily, Impel Down, and Marineford. He has saved and defeated the Straw Hat Pirates on two occasions, and protected the Thousand Sunnyduring their two-year absence by making a deal with Vegapunk to have that mission programmed as his primary objective.
