Pirate King Bruce, also transliterated as Blues, carved his legend as a space pirate by pulling off the largest heist in galactic history: stealing ten billion space dollars from the supposedly impenetrable Central Bank. Intriguingly, Bruce orchestrated the vault theft from within, having risen to CEO-level authority through revolutionary management reforms that earned the bank billions. This ascent proved his primary drive was the thrill of piracy itself, not financial gain.

He meticulously infiltrated the bank over an extended period, climbing the corporate ladder to secure the necessary clearance. Bruce bypassed the vault's elaborate security, later replicating it to build his own custom vault on Graceland to safeguard the stolen fortune. During the heist, he employed an artificial eye recording his visual experiences; a fragment of this eye was set into a necklace given to his daughter, Franca.

Bruce cherished Franca above all. Upon his death, he entrusted her care to a fellow coyote named Mister, bypassing his longtime "right-hand man" Swamp Gordon. This decision reflected Mister's deeper grasp of Bruce's core values and loyalty. Madame Marciano, leader of a galactic criminal guild, murdered Bruce three years before the series' main events, with Franca witnessing the act. His recorded message inside the Graceland vault revealed his true legacy lay not in riches, but in personal mementos for Franca, declaring her his real treasure.

Bruce defined himself by rejecting stability for adventure, his devotion to Franca, and embodying the coyote ethos—prizing loyalty to chosen family over societal norms or material wealth. His actions after death ignite the series' central conflict, as multiple factions hunt his hidden fortune on Graceland.
