CP-0, more properly known as Cipher Pol Aigis Zero (サイファーポール"イージス"ゼロ Saifā Pōru Ījisu Zero?) is the strongest intelligence organization among Cipher Pol. They first appeared on Dressrosa near the bridge to Green Bit.
- The shortest one wears a white bowler hat, a dark purple and blue polka dotted scarf, a white long coat, and what looks like a dark blue, light yellow-gold, red award ribbon on his blazer. He wears his tie loosely. He has a flat face with a thin mustache and beard, a scar under his light-colored right eye, and markings under his pure black left eye. What appears to be a mask seems more likely to be white make-up, as his mouth was moving while he addressed the people. His voice actor is Katsumi Suzuki.
- The one of middle height wears a vertically striped red and white hat and a white coat with a frilly rim. Their mask has a light yellow flowery beard, a thin dark blue smile, all white-colored eyes, and two blue vertical lines going down the right side.
- The tallest one has a brush-like, slightly muted, periwinkle blue-colored beard. He wears a white long robe and a white beaded necklace with a light blue bead in the middle. His mask is a dark red angry looking with thick and almost dreadlock-like, flat pure black-colored hair. He later appears in Heart of Gold, where his voice actor is Katsumi Suzuki.
A fourth unnamed agent was seen in Wano Country discussing the trading terms with the shogun, Kurozumi Orochi, along with two who were seen in Dressrosa (the agents wearing white masks). The agent seems to be taller than the other agents though they were only seen sitting down. The agent has a light colored mask with round eyes and a cylinder mouth that sticks out, a high hat, and a long holding stick that the agent grasps with both hands in front of themselves. Like most CP-0 members, the agent wears a white suit and cape.
CP-0 is the strongest of all Cipher Pol units, even surpassing the assassination specialists of CP9. It is said that nothing good can come from this group's presence as stated by Robin. They work directly under the command of the World Nobles.
When word of Donquixote Doflamingo's supposed abdication of his throne and Warlord of the Sea position reached the citizens of Dressrosa, Doflamingo called CP-0 to come and clear up the confusion. When they arrived, they told the people that the article printed in the newspaper was a mistake. They went on to explain that a new, amended report would be released at 3 p.m. that day. Finally, they asked the citizens not to discuss the rumors until the truth was released and to conduct usual activities as if nothing had happened.
Doflamingo revealed to Law that he was granted authority to command CP-0 because he holds secret information about Mary Geoise's "national treasure", which will shake the world if its existence is revealed to the public.
Spandam, Kaku, Rob Lucci, and Hattori arrived there days later. They received a message telling them that all weapons from the underground port were taken. They suspected the Revolutionary Army to be behind the incident.

Spandam came to Gran Tesoro, where he received a magnificent payment from Gild Tesoro in order to bring his forces to Gran Tesoro and help Tesoro's crew deal with the Straw Hat Pirates. Lucci reported to Sakazuki about Marine involvement in Gran Tesoro. Sakazuki was angry that they were helping a pirate, but Lucci replied that the Marines had their own motives.
The next night, as the Straw Hats and the citizens of Gran Tesoro were battling Tesoro's crew, Spandam prepared to finish Luffy off, but Rikka blocked Spandam's strike, giving Luffy enough time to free himself and punch Spandam, defeating him. Lucci and a Marine fleet attacked Gran Tesoro, intending to destroy it despite the call for help from the World Nobles on board as well as the innocent people. However, Sabo suddenly appeared and stopped the bombardment. Lucci then turned into his leopard hybrid form, and the two clashed. The two battled until Gild Tesoro's defeated body fell in between them, and Lucci took his leave from the battle.

Whole Cake Island Arc
When Du Feld attempted to steal the Tamatebako, Stussy confronted him and questioned him of his intentions. Surprised by her sudden appearance, he fell down to where the Tamatebako had fallen to earlier. As he was about to open the chest, Stussy shot him down with a Tobu Shigan. Stussy stated that the World Government would have better use of the item before telling an eavesdropping Morgans to fabricate a story with Du Feld as the culprit of its theft. Morgans begrudgingly complied but demanded to see the contents of the Tamatebako first. She agreed, but Du Feld's unconscious body knocked over the chest, sending it to the base of the Whole Cake Chateau. The Tamatebako, which held a bomb, detonated and the explosion caused the Whole Cake Chateau to collapse. As the chateau toppled, Stussy managed to avoid harm using Geppo.
As the Big Mom Pirates chased the Straw Hats throughout Totto Land, Stussy waited with Morgans near Charlotte Mont-d'Or's operating center. She then informed them about the Tamatebako being the cause of the explosion and heard their plan of vengeance, before leaving with Morgans. Aboard Morgans' balloon, she talked about Morgans' support of Monkey D. Luffy and his prediction regarding the Worst Generation.
The day before the Levely began, Charlos tried to take Princess Shirahoshi as his pet. When Leo and Sai tried to save her, they were blocked by Lucci's team. When Neptune prepared to attack Charlos despite the threat of striking a World Noble, Charlos ordered Lucci to kill him. However, Donquixote Mjosgard arrived and knocked out Charlos, defusing the event, and ordered the release of Shirahoshi.

Wano Country Arc
With Doflamingo's defeat and arrest, the World Government was having a hard time acquiring more weapons that originated from Wano Country through their primary intermediate. As a result, CP-0 agents went directly to Wano to negotiate with Shogun Kurozumi Orochi. Orochi accepted their payment in the form of warships, but informed them that if another trade were to happen, Vegapunk would be required as payment. The agents found the request to be an impossibility and in response, Orochi shot one of the members (who was not injured by any more than a simple recoil) and mocked them that he had Kaido backing him, and therefore was not afraid of the World Nobles nor the Marines.
The CP-0 agents were later invited to Onigashima on Orochi's behalf for the Fire Festival. During the raid led by the Ninja-Pirate-Mink-Samurai Alliance, the agents lamented on Orochi's death and analyzed the state of the conflict.
Later, the leader thought back to when Kaido had been captured by the Marines and how Dr. Vegapunk experimented on his Lineage Factor, thus creating an artificial Devil Fruit. The World Government wanted him to give the fruit to them, but Vegapunk considered it a failure and refused, leaving it on Punk Hazard. One of the other agents asked why he was bringing this up now since Punk Hazard was destroyed, but the leader said that he hoped the fruit was destroyed as well despite the G-5 reporting that one facility was still operational.
- The "Aigis" in "Cipher Pol Aigis Zero" may be derived from the Aegis, a mythological shield associated with Zeus and Athena shown as a short goatskin cloak. Athena's aegis is usually shown with a border of snakes and with the head of Medusa in the center. It is more an emblem of protection and power than an actual military shield.
- The three unidentified CP agents who met Carmel wear white outfits and tribal masks, features they share with most of other CP-0 agents, althought they're not confirmed as members of it.
- Stussy and Kaku are the only CP-0 agents to not wear any mask so far.
- Spandam is the only CP-0 agent to wear a not tribal nor carnival mask, as he actually has a white version of his old one.
- CP-0 is written as "CP AISIS 0" in One Piece Volume 777.
