Eustass “Captain” Kid is a notorious pirate from South Blue and the captain of the Kid Pirates. He is one of twelve pirates who are referred to as the “Worst Generation”.
During the timeskip, Kid lost one of his arms in a confrontation against one of the Four Emperors, Shanks, and attempted to form an alliance with the On Air Pirates and Hawkins Pirates to challenge the Red Hair Pirates once more, but it was eventually disbanded due to an encounter with another Emperor, Kaidou.
Kid was originally introduced with a bounty of $315,000,000, largely due to a high number of civilian casualties caused by him and his crew, thus exceeding Luffy’s when they first arrived at the Sabaody Archipelago. Sometime during the timeskip, his bounty was raised from 315,000,000 to – 470,000,000. Kid’s bounty was eventually raised to $,000,000,000 for his role in defeating Big Mom of the Four Emperors alongside Trafalgar Law during the Wano Country Arc.
