In the vast narrative of One Piece, the Marines are generally positioned as adversaries. However, numerous Marine characters have garnered substantial screen time and development. Amid the World Government’s orders for morally questionable actions to uphold the societal balance, many Marines form individual beliefs regarding their roles and duties within the broader context of this world.
Whether driven by unwavering loyalty or rebellious inclinations, several Marine characters have embarked on captivating adventures and personal journeys throughout the long-running saga of One Piece.
8. Sengoku
The Power Behind Sengoku’s Stoic Persona

Although Sengoku’s tenure as Fleet Admiral is brief before Akainu takes over, he firmly establishes the reasons behind his ascension to this prestigious title. His decisive actions during the Marineford War, including his commitment to executing Ace, reveal his resolute dedication to eradicating piracy and enforcing justice in the world. This includes restraining Garp during the conflict when Garp attempted to rescue Ace, a testament to the cold-hearted resolve necessary for a Fleet Admiral.
Fans primarily remember Sengoku for his transformation into a gigantic golden Buddha, an ability granted by the Hito Hito no Mi fruit. His sheer size and formidable punches can devastate large areas. Despite being portrayed as a reclusive figure in the post-timeskip, Sengoku’s legacy and formidable Devil Fruit abilities continue to distinguish him within the Marine ranks.
7. X Drake

Initially introduced as part of the Worst Generation of pirates, X Drake’s past is shadowed by rumors of his former life as a Marine before embracing the pirate lifestyle. His character reaches new depths during the Wano arc, where, while masquerading as a member of Kaido’s Tobi Roppo, he secretly fetches valuable intelligence for the Marines as a spy.

6. Smoker
Smoker’s Complex Relationship with Pirates

- First Appearance: Episode 48
When he first appears in Loguetown, Smoker is adamantly focused on eradicating pirates, viewing them merely as scum. However, after the Straw Hats save him in Alabasta, his perspective starts to shift, particularly after witnessing Luffy defeat Crocodile—a feat the Marines are only too eager to take credit for.
This transformation constructs a compelling personal arc for Smoker, marked by internal conflict and unpredictability, making his appearances all the more captivating. His intriguing moral dilemmas and distinctive character design have endeared him to audiences.
5. Kizaru
Kizaru’s Charisma and Depth

- First Appearance: Episode 398
Kizaru stands out as one of the most flamboyant and charismatic Marines in the series. Not only does he move effortlessly across battlefields at lightning speeds, unleashing destructive force with his abilities, but he often intersperses combat with humor, belittling adversaries. However, recent developments on Egghead Island unveil a more intricate side to Kizaru’s character.
Having served the Marines for decades, Kizaru has cultivated numerous bonds, making him empathetic to emotional ties, such as his connection to Vegapunk, which can complicate his missions. Unlike many of his fellow Marines, Kizaru balances an outwardly cheerful demeanor with obscured personal feelings, adding to his allure.

3. Akainu
Akainu: The Personification of Absolute Justice

- First Appearance: Episode 278
Akainu’s character is inherently detestable, not due to poor writing, but because of his unyielding ruthlessness. As a proponent of “Absolute Justice,” he demonstrates a willingness to eliminate not only pirates but anyone deemed a threat to the status quo, a stark example being his destruction of Ohara Island for housing those seeking to uncover historical secrets.
His relentless nature, responsible for Ace’s death and his rise to Fleet Admiral status by defeating Aokiji, significantly influences the overarching narrative. However, Oda subtly reveals glimpses of Akainu’s emotional depth, suggesting potential character growth in the future.

This courageous stance places him directly at odds with Fleet Admiral Akainu, providing thrilling confrontations that highlight his defiance.
His nomadic tendencies often lead him to act independently of orders, showcasing his rebellious spirit. Additionally, Fujitora’s gravity-manipulation abilities allow for breathtaking displays of power, such as his meteor summoning in Dressrosa, revealing an immensely destructive capability lurking behind his calm facade.
