Bruce Dockley, also transliterated as Blues Dochley, earned the legendary title "Pirate King" within the criminal underworld. His most infamous feat involved successfully stealing ten billion space dollars from the supposedly impenetrable Central Bank. Notably, Bruce held an exceptionally high-paying position at that same bank during the heist, indicating his actions stemmed more from the thrill of piracy than financial need.

He held deep care for his daughter, Franca Dockley. Shortly before his death, Bruce entrusted Franca's care to his associate known only as Mister. This decision fostered lasting resentment in Swamp Gordon, Bruce's self-described "right-hand man" or "right arm," who believed he deserved the responsibility. Bruce possessed an artificial eye that functioned as a recording device, documenting everything he witnessed.

Three years before the series events, Madame Marciano, a high-ranking official in a powerful criminal syndicate, killed Bruce. Her motive stemmed from intense hatred of "coyotes" – outlaws defined by refusing to betray companions – whom she blamed for robbing her of her dreams. It is hinted Marciano may have harbored past personal connections or regrets concerning Bruce, though she publicly denied any such feelings.

Bruce bequeathed the stolen fortune to Franca, concealing it within a complex, custom-built vault on the planet Graceland. Access required a specific pendant he gave to Franca, serving as the key to locate the treasure. His legacy drove the central plot as multiple factions raced to claim the treasure before Graceland's destruction.
