One Piece: 5 Notable Pirates Who Served as Double Agents

Essential Insights

Within the world of One Piece, certain pirates operate as spies, embedding themselves in various crews to gather information.
These spies can encounter dire repercussions, including exposure, death, or being coerced into collaboration with adversaries.
Notable examples include characters like Vivi, Rosinante, and Vergo, each betraying the organizations with which they were allied.

Often labeled as criminals in both title and behavior, the pirates of One Piece frequently engage in deceitful acts. Some resort to dishonesty or treachery when it benefits them, whereas others take the guise of infiltration to serve their ulterior motives. A number of formidable pirates focus on gathering intel against potential threats, leading a select few to integrate themselves covertly into rival crews for intelligence collection.

At times, these infiltration acts are not commissioned by other pirates but are personal plots. Below are instances of pirates who served as double agents, always harboring intentions to betray the organizations they infiltrated.

5 Nefertari D. Vivi

The Pirate Princess

Debut: Chapter 103 (Manga), Episode 62 (Anime)
Served as a Double Agent for Alabasta while briefly aligning with the Straw Hat crew (Infiltrated Baroque Works)
Devil Fruit: None

Though Vivi’s foray into piracy occurred by chance, her loyalty remained with the kingdom of Alabasta, not the criminal organization Baroque Works, which sought to dominate her homeland. Vivi and her royal guard captain, Igaram, successfully integrated into Baroque Works, reaching notable ranks and gaining significant insights into their operations. Once their true intentions were unveiled, Igaram implored the Straw Hat Pirates to ensure Vivi’s safety out of concern for Alabasta.

In the end, Vivi became a member of the crew only after her role as a double agent was exposed. Following the defeat of Baroque Works, she returned to her royal responsibilities. Nonetheless, the loss of her father, Cobra, and her ongoing fugitive status have led many fans to speculate about her potential return to piracy in the future.

4 Donquixote Rosinante

An Undercover Marine

Rosinante dies with a smile on his face, knowing he was able to save Law.

Debut: Chapter 761 (Manga), Episode 686 (Anime)
Operated as a Double Agent for the Marines by infiltrating the Donquixote Pirates
Devil Fruit: Nagi Nagi no Mi

Rosinante belonged to the Donquixote family, specifically a branch that willingly relinquished their noble status, which ultimately led them to a life of hardship and social ostracism. While Rosinante’s upbringing fostered a sense of morals, his brother Doflamingo descended into villainy, ultimately forming the Donquixote Pirates. Doflamingo’s actions prompted Rosinante to distance himself and join the Marines under Admiral Sengoku’s mentorship, eventually becoming a Commander.

Sengoku tasked Rosinante with a crucial mission: infiltrate his brother’s pirate crew and relay information on their activities. For a time, Rosinante deceived the Donquixote Pirates, winning over Doflamingo, who gave him the alias Corazon. However, his cover was ultimately blown thanks to Vergo, Doflamingo’s own spy within the Marines. Before his tragic end, Rosinante formed a significant bond with Trafalgar D. Water Law, a young boy in dire health, and played a pivotal role in Law’s determined quest for vengeance against Doflamingo.

3 Rod

The Donquixote Spy

Vergo Fighting Smoker and Law With Full Body Busoshoku Haki In One Piece

Debut: Chapter 671 (Manga), Episode 597 (Anime)
Functioned as a Double Agent for the Donquixote Pirates (Infiltrated the Marines)
Devil Fruit: None

In stark contrast to Rosinante, the original Corazon actively supported Doflamingo’s criminal enterprises. He was renowned for his mastery of Armament Haki, capable of enveloping his entire body in it, and often sported food remnants on his face. Vergo was a major figure in Doflamingo’s crew but, at the same time, served as a covert operative within the Marines. His undercover role eventually led to Rosinante’s unmasking as a traitor.

Vergo remained committed to his dual life, but when he unburdened his true loyalties to Marines like Smoker and Tashigi during their captivity on Punk Hazard, it resulted in significant backlash when their coalition escaped. Vergo met his fate in the SAD Production Room due to Doflamingo’s machinations, who appeared to have orchestrated his demise with a heavy heart.

2 Scratchmen Apoo

Informant for Kaido

Debut: Chapter 498 (Manga), Episode 392 (Anime)
Served as a Double Agent for the Beasts Pirates (Infiltrated the Pirate Alliance with the Kid Pirates and Hawkins Pirates)
Devil Fruit: Oto Oto no Mi

Amid the conflicts involving the Worst Generation and the Emperors, one failed alliance emerged among the Kid Pirates, the On Air Pirates, and the Hawkins Pirates, aimed at confronting the formidable Beasts Pirates under Kaido’s command. Although Kaido’s might should have deterred most, the alliance’s inherent flaws led to its downfall.

From the onset, this alliance was compromised due to Apoo’s secret alliance with the Beasts Pirates prior to the venture. His intention was to use this alliance to further integrate the other captains into Kaido’s ranks. While some like Hawkins did join, others resisted, leading to a splintering of their collective efforts. Ultimately, Apoo’s cowardice and lack of dedication to Kaido became evident as new allegiances formed, particularly between Kid and Luffy.

1 X Drake

Operative in the Black Ops Unit

X Drake strongest rear admiral one piece

Debut: Chapter 498 (Manga), Episode 392 (Anime)
Functioned as a Double Agent for the Marines (Infiltrated Beasts Pirates)
Devil Fruit: Ryu Ryu no Mi, Model: Allosaurus

X Drake’s journey into piracy began with his father, a former Marine, although he chose the opposite path for a time by becoming a Marine himself. Rising to Rear Admiral, he ultimately returned to piracy, for reasons still unclear. His marine background provided him insights into projects like the Pacifista program, which few pirates were aware of.

Drake sought to confront Kaido directly, drawing attention to his crew with a significant attack. Though initially welcomed into the Beasts Pirates and granted a high-ranking position within the Flying Six, he soon found himself at odds with Kaido’s plans. As suspicions of his loyalty grew, Drake allied himself with Luffy, revealing his true motives connected to SWORD, an elite marine unit comprising former members without the usual constraints. The extent of his crew’s knowledge regarding his secretive dealings remains ambiguous, leaving fans eager to see what his next move will be.
