Red Flag X Drake (pronounced as Diez Drake) is the captain of the Marine Secret Special Unit SWORD. In order to go undercover as a pirate, he publicly defected from his position as rear admiral[8] and founded the Drake Pirates.[2][1] He is one of twelve pirates referred to as the Worst Generation,[13] and before the two-year timeskip had a bounty of Beli222,000,000.[1]

Drake is the son of the Marine-turned-pirate Diez Barrels, and was affiliated with the Barrels Pirates until he defected to the Marines. As a young adult, he was called Dory.[6][14]

In Drake's endeavor as an undercover spy,[2] he and his crew became subordinate to the Beasts Pirates, led by Kaidou of the Four Emperors, over the two-year timeskip.[3] Drake served as one of the crew's Shinuchi, specifically one of strongest six called Tobiroppo.[4] His treachery was eventually uncovered, however, leading him to ally himself with the Ninja-Pirate-Mink-Samurai Alliance.[5]
