Overview of Corrupt Marines in One Piece
- Not all Marines in One Piece embody heroism; numerous characters exhibit corruption and incompetence.
- Individuals like Fullbody, Ratel, and Nezumi are highlighted for their poor decisions and unethical behavior.
- High-ranking Admirals, such as Sakazuki and Ryokugyu, are driven by extreme ideologies, leading to their ruthless actions.
The universe of One Piece portrays a stark contrast between two primary factions: the Pirates, often depicted as treasure-hunters and villains, and the Marines, serving as the military arm of the World Government aiming to protect civilians from pirate threats. However, the narrative reveals a more complex reality where many Marines fail to live up to the heroic ideals they are supposed to uphold.
As the series unfolds, viewers encounter many Marine officers who prove to be inadequate in their roles, regardless of their status within the organization. This discussion focuses on characters who exemplify poor conduct within the Marine ranks for in-universe reasons, rather than merely for subjective viewer opinion.
8. Fullbody
An Obsession Fueled by Disrespect


- Debut: Chapter 43 (Manga), Episode 20 (Anime)
Known as “Double Ironfist”Fullbody, this former lieutenant made his entrance during the Baratie Arc, immediately showcasing arrogance and rudeness. He is more interested in romantic pursuits than fulfilling his duties and even attempts to provoke a fight with Sanji—an endeavor that ends poorly for him.
His superficial act of supporting Jango in court after they jointly battled a pirate crew earns him a demotion for his dubious actions. Ultimately, Fullbody’s primary focus seems to be his fixation on Rear Admiral Hina rather than effective service.
7. Ratel
Exploiting Civilians for Treasure


- Debut: Chapter 1073 (Manga), Episode 1105 (Anime)
Marine Captain Ratel’s brief appearance left a negative impression. He invaded Sphinx during Marco’s search for Whitebeard’s treasure, terrorizing the locals under the flimsy excuse that the island wasn’t recognized by the World Government.
His actions exemplified cruelty born of greed, demonstrating a blatant disregard for innocence. Ratel’s misdeeds ultimately lead to his downfall when he is effortlessly defeated by Edward Weevil.
6. Nezumi
Corruption Alongside Pirates


- Debut: Chapter 69 (Manga), Episode 31 (Anime)
Eiichiro Oda, creator of the series, crafts characters with unmistakable designs, and Nezumi exemplifies this trend with his rat-like appearance, signaling his greed and corruption.
During the reign of the Arlong Pirates over the Conomi Islands, Nezumi ignored their terror in exchange for bribes, ultimately assisting in theft from Nami’s efforts to liberate her village.
5. Axe-Hand Morgan
A Power-Hungry Abuser


- Debut: Chapter 4 (Manga), Episode 2 (Anime)
Axe-Hand Morgan stands as a significant figure in the narrative, introducing the archetype of a corrupt Marine. As a captain in Shells Town, he misused his authority to instill fear, imposing exorbitant taxes and executing dissenters.
His spoiled son, Helmeppo, thrived under this tyrannical rule, running amok until Zoro intervened. Ultimately, Morgan’s reign ended after he was defeated and tried for his crimes, yet he managed to escape justice.
4. Vergo
A Double Agent in Marine Ranks


- Debut: Chapter 671 (Manga), Episode 597 (Anime)
“Demon Bamboo”Vergo was perceived as an esteemed Marine officer, yet he was secretly loyal to the Donquixote Pirates. His relationship with Doflamingo was an elaborate deception that allowed him to spy from within the organization.
His actions contributed to the tragic death of fellow Marine Corazon and cast a long shadow over his supposed duty to protect the innocent.
3. Monkey D. Garp
The Marine Hero with a Flawed Conscience


- Debut: Chapter 92 (Manga), Episode 68 (Anime)
Monkey D. Garp is revered as a character who understands the World Government’s inherent corruption. He famously refuses an admiralship, opting instead to act according to his values, including protecting figures like Ace.
Despite his heroic reputation, Garp’s actions often rub the World Government the wrong way, as he tends to prioritize his own sense of justice over strict obedience to orders.
2. Sakazuki (Akainu)
The Cruel Enforcer of Absolute Justice


- Debut: Chapter 397 (Manga), Episode 278 (Anime)
Sakazuki, also known as Akainu, stands out for his uncompromising belief in Absolute Justice. This dogma leads him to categorically label all pirates as evil, resulting in ruthless actions that disregard innocent lives.
His brutal methods, including the killing of Marines during the Paramount War, paint a troubling picture of a man whose definition of justice breeds fear rather than safety.
1. Aramaki (Ryokugyu)
The Arrogant Enforcer of Nobility


- Debut: Chapter 905 (Manga), Episode 882 (Anime)
Unlike Akainu, who demonstrates a twisted commitment to his version of justice, Ryokugyu (also known as Aramaki) reveals a dangerous admiration for the Celestial Dragons. His elitist perspective renders him utterly dispassionate toward anyone outside that class, leading to acts of violence and cruelty in the name of loyalty.
Aramaki’s blind allegiance results in failures, such as his retreat from Wano after facing Shanks and his inability to thwart the Revolutionary Army during the Levely, raising questions about his effectiveness and loyalty.
