CP0
CP0, officially known as Cipher Pol Aegis Zero, is the World Government's premier and most secretive intelligence and covert operations unit in the manga and anime series One Piece. Tasked with protecting the stability and interest of the World Government and the Five Elders, CP0 operates with exceptional authority, executing sensitive missions that influence global politics, military affairs, and information control across the Grand Line and beyond.
CP0 functions as the highest echelon of the Cipher Pol network, acting as the direct enforcement arm and intelligence conduit for the Five Elders seated in Mary Geoise. Unlike its sibling agencies such as CP9 and CP1, CP0 is empowered to override regional commands, manage diplomatic covert actions, and carry out preemptive operations against perceived threats to the World Nobles and international order. Its mandate includes clandestine surveillance, counterintelligence, sanction enforcement, and the suppression of challenges to the World Government's legitimacy, including insurgent revolutionary activity and exposure of forbidden knowledge like the Void Century.
CP0's origins are partially obscured by classified records within Mary Geoise. Historically, Cipher Pol units trace back to the early consolidation of the World Government following the end of the Void Century, evolving from palace guards and imperial informants. CP0 is widely regarded as the successor to earlier elite units such as CP1–CP9, reconstituted during periods when the World Government required a permanent, politically independent intelligence bureau. Key moments in CP0's history include interventions around the Enies Lobby arc aftermath, involvement in affairs surrounding the Sabaody Archipelago and Wano Country's international repercussions, and their reappearance during shifts in the Four Emperors balance of power.
Formally part of the Cipher Pol umbrella, CP0's internal hierarchy is compact and vertical, reporting directly to the Gorosei. Operatives are selected for loyalty, discretion, and combat prowess, with ranks that mirror intelligence-service structures: field agents, senior operatives, squad chiefs, and a central director known colloquially as the "Aegis." CP0 maintains detachments embedded within diplomatic missions and an independent command in Mary Geoise. Unlike public military branches such as the Marines, CP0's personnel wear unmarked or diplomatic attire and enjoy diplomatic immunity granted by the Tenryuubito, enabling legal cover for extraterritorial actions.
Several named figures associated with CP0 have emerged in canonical narratives. These include high-profile operatives directly engaged in missions affecting Monkey D. Luffy's allies and rival powers, clandestine agents linked to the handling of Sabo's status and the tracking of Revolutionary Army members, and senior CP0 representatives who negotiated or monitored events at Punk Hazard and Egghead Island. Former CP9 agents and other Cipher Pol alumni have been rumored or shown to transition into CP0 ranks, providing institutional continuity in interrogation, assassination, and intelligence tradecraft.
CP0 has conducted discreet operations with major geopolitical impact: surveillance and intervention related to the Sabaody Archipelago slave trade, monitoring of shichibukai arrangements prior to their dissolution, and involvement in the aftermath of the Marineford war to secure state secrets. They have also been implicated in efforts to suppress dissemination of information about Poneglyphs and the Road Poneglyphs, managing access to Rio Poneglyph knowledge that might destabilize the World Government. CP0's hand is evident in maneuvering around the Dressrosa and Whole Cake Island arcs through intelligence sharing and targeted pressure on political figures.
CP0 operatives exhibit a blend of high-level espionage skills, advanced interrogation techniques, and combat abilities; many are trained in assassination, stealth infiltration, and counter-surveillance. They employ cutting-edge weaponry available to the World Government, including Seastone restraints for Devil Fruit users and specialized firearms, as well as diplomatic cover and legal instruments to shield operations. Tactically, CP0 favors surgical strikes, deniable operations, bureaucratic coercion, and psychological warfare to maintain social order and the primacy of the World Government. Their training overlaps with that of CP9's Rokushiki masters, though CP0's scope emphasizes strategic outcomes over martial display.
CP0 maintains complex relations across One Piece's power network. As the World Government's top covert organ, it coordinates with the Marines for joint operations when plausible but often acts independently or in competition with field commanders. Its rivalry and occasional cooperation with other Cipher Pol branches like CP9 reflect institutional specialization. CP0 engages diplomatically and covertly with the Revolutionary Army, Yonko informants, and former Shichibukai contacts to manipulate outcomes in favor of global stability. Internationally, CP0 leverages relationships with Celestial Dragons and regional regimes to enforce the World Government's policies, while its secrecy fuels mistrust among pirates, revolutionaries, and independent states such as Wano Country and Dressrosa.
