CP5, formally Cipher Pol Number 5, is a World Government intelligence branch once headed by Spandam. Lacking real combat prowess, its agents lean on firearms and covert work, and they figured into Spandam's scheme to seize the Pluton blueprints.
Operating as one of the Cipher Pol units under the World Government, CP5 had Spandam at its head for a time. Its precise specialty is never spelled out, though the group showed competence in stealth, theft, navigation, and the handling of unusual weaponry, and it held enough standing to weigh in on questions of Justice. What the unit clearly lacked was fighting strength: rather than superhuman techniques, its agents simply relied on firearms to make arrests.
The group's defining act traced back to Spandam's manipulation of the Five Elders, whom he talked into reversing their stance on the Ancient Weapons so he could pursue Pluton's plans. Years later he led agents to Water 7 to pry the blueprints from Tom, who denied any knowledge of them. To frame Tom's Workers, Spandam had his men commandeer Cutty Flam's battleships to assault the Judicial Ship, pinning the attack on Tom, Cutty Flam, and Iceburg. Tom was condemned to death while the two apprentices escaped sentencing. The agents then ferried Tom to Enies Lobby aboard the Puffing Tom. Soon after, Spandam departed CP5 to take charge of CP9.
Spandam stands as the unit's best-known leader before his promotion to CP9. In the Final Saga, a CP5 ship sent to Egghead to probe Vegapunk's research into the Void Century turned up nothing, and on departure York had the Sea Beast Weapons wreck their vessel and lock them in an unused lab. CP7 and CP8 agents who came searching met the same fate. The captured agents, half-starved, were eventually freed and fed by the Straw Hat Pirates before the chaos on the island swept them into the Marines' hands.

When I first decided to commit to watching One Piece seriously, I knew I was embarking on one of anime's longest and most beloved series. With over 100...

The transformation everyone knows, the follow-up question nobody would touch. Why we made a smooth R&B track about the golden glow Dragon Ball never talks about....
CP5, formally Cipher Pol Number 5, is a World Government intelligence branch once led by Spandam. Its agents lack real combat strength and instead rely on firearms, stealth, and covert work to make arrests.
CP5 agents, acting on Spandam's orders, traveled to Water 7 to seize the Pluton blueprints from the shipwright Tom, who denied knowing anything about them. Spandam then had his men hijack Cutty Flam's battleships to attack the Judicial Ship and frame Tom's Workers for it.
Spandam served as CP5's best known leader before he was promoted to take charge of CP9.
A CP5 ship sent to Egghead to investigate Vegapunk's research into the Void Century found nothing, and when it tried to leave, York used the Sea Beast Weapons to destroy the vessel and trap the crew in an unused lab alongside captured CP7 and CP8 agents.
The starving CP5 agents held on Egghead were eventually freed and fed by the Straw Hat Pirates, though the island's ensuing chaos soon left them in the custody of the Marines.
