His introduction in the Jaya Arc is marked by his plundering and brutal beating of Montblanc Cricket and his crew, showcasing his disdain for those who pursue dreams and his cynical view of the world.

This cruelty is further highlighted in his violent confrontation with Luffy, where Bellamy’s arrogance and mercilessness are on full display. His philosophy, heavily influenced by the Era of Might, under the shadow of his idol, Doflamingo, reflects a dark, cynical worldview where power and mockery reign supreme.

Government Assassin

Rob Lucci’s Dark Characteristics

Lucci initially appears as a seemingly benign shipwright named Lucchi, working undercover in the Galley-La Company. His true nature is revealed when other CP9 agents are exposed as the culprits behind the attempted assassination of Iceburg, the Mayor of Water 7.

Lucci’s dark nature is also exemplified in his backstory, where, as a child, he massacred 500 soldiers and prisoners to quell a revolt, showing his early embrace of extreme measures. Lucci demonstrates a disturbing willingness to commit atrocities for the World Government.

Lightning God

Wielding the immense power of the Goro Goro no Mi, a lightning-based Devil Fruit, he forecibly enforces his will upon the inhabitants of Skypiea. His dark nature is vividly illustrated when he destroys Angel Island, showcasing his disregard for human life.

Enel’s plan to obliterate Skypiea with his Ark Maxim further cements his status as a tyrant. However, this plan ends in a fierce battle with Luffy. Enel’s actions are driven by a belief in his invincibility and a desire to assert his godhood, making him a darkly megalomaniacal character.

Master Of Shadows

Gecko Moria’s Dark Characteristics

• Disregards the value of life
• Creates zombie army from shadows

Gecko Moria, the shadow-manipulating Shichibukai, is a dark character due to his unique abilities and actions. He rules over Thriller Bark, a massive ship island filled with undead creatures, a direct result of his Devil Fruit power, the Kage Kage no Mi. Moria’s darkness is evident in his exploitation of corpses and shadows to create zombie armies.

His past tragedy at the hands of Kaido, which led to the loss of his original crew, fuels his macabre approach to piracy, opting to use the undead rather than risk living comrades. This obsession with using others for his gain and his eerie, graveyard-themed abode underscores his dark nature.

11 Buggy

Star Clown

Buggy’s Dark Characteristics

• Forms alliances for personal benefit
• Vengeful towards those who cross him

As a former member of the Roger Pirates, Buggy was part of the most notorious crew in One Piece. His cruelty is first revealed when he mercilessly attacks Zoro and Nami.

Despite his often humorous demeanor, Buggy’s actions in Loguetown, where he nearly executes Luffy, further illustrate his darker nature. One of the most notable changes for Buggy after the time skip is his elevation to the status of a Shichibukai, or Warlord of the Sea. Capitalizing on his newfound status, Buggy establishes Buggy’s Delivery, a mercenary dispatch service.

His initial plan to live a peaceful life by faking his death and assuming the identity of Klahadore, a butler, takes a sinister turn when he plots to kill his benefactor, Kaya, for her wealth.

Kuro’s past as the Captain of the Black Cat Pirates reveals his brutal nature, highlighted when he slaughters his own crew members to maintain his cover.

His primary dark deed is his attempt to take over the Kingdom of Alabasta. He meticulously orchestrates a civil war by employing Baroque Works agents, like Mr. 2 (Bon Clay) and Miss All Sunday (Nico Robin), to manipulate the royal family and the rebel forces.

Crocodile uses his powerful Devil Fruit, the Suna Suna no Mi, and Dance Powder to dry the land of its resources by preventing rainfall. His willingness to sacrifice countless lives and his manipulation of an entire country’s political and social structure for power highlight his dark character.

8 Arlong

Vindictive Tyrant

Arlong’s Dark Characteristics

• Deep-seated hatred for humans
• Extorted money for survival

Arlong, the leader of the Arlong Pirates and a former member of the Sun Pirates, is a dark character due to his deep-seated hatred for humans and brutal treatment of them. Arlong invades Nami’s village, Cocoyasi Village, imposing a tyrannical rule and forcing the villagers to pay a large tax for their lives.

His cruelty is most notably seen in his treatment of Nami. He manipulates her skills as a cartographer to further his own goals and keeps her under his control through a combination of intimidation and false promises. Arlong’s disdain for humans stems from his history of oppression under humans but manifests in extreme violence and oppression.

His cruelty is also starkly evident in his experiments on children, whom he abducts and gives drugs under the guise of treatment, causing severe side effects like accelerated growth. Caesar’s actions, driven by ego and greed, make him a darkly twisted and dangerous character.

Impel Down’s Warden

Magellan’s Dark Characteristics

• Uses deadly poison against prisoners
• Shows little empathy towards inmates’ suffering

Magellan’s Devil Fruit power, the Doku Doku no Mi, allows him to produce and control various types of poison, which he uses without hesitation against prisoners and intruders.

This is evident in his battles with Luffy during the Impel Down Arc, where his poison nearly kills him. Despite his loyalty to the World Government and sense of duty, Magellan’s extreme methods, willingness to dispense deadly force, and the harsh conditions he oversees in Impel Down paint him as a dark figure.

Cruel Pirate Captain

Eustass Kid’s Dark Characteristics

• Violent approach to solve problems
• Willing to harm civilians if they mock him

His cruelty is first shown when it’s revealed that he crucifies defeated pirates and leaves them to die, a testament to his brutal approach to piracy. Unlike many other pirates who avoid civilian casualties, Kid has no such qualms about harming civilians.

His magnetic Devil Fruit powers are used in destructive and aggressive ways, further emphasizing his violent tendencies. Kid’s rivalry with Luffy and his participation in significant events like the Sabaody Archipelago incident and the Wano Country Arc also highlight his aggressive and unyielding nature.

His merciless nature is further highlighted in his relentless pursuit of Luffy and Ace, culminating in Ace’s tragic death by his hand.

Akainu’s willingness to sacrifice anything, including innocent lives, as seen in the Ohara incident, for his version of justice makes him a darkly formidable character. He represents the oppressive and uncompromising side of the World Government, willing to enact extreme measures for peace and order.

3 Kaido

Beast Emperor

His introduction in the Wano Country Arc, where he mercilessly defeats Luffy with a single blow, demonstrates his overwhelming strength and lack of empathy.

Kaido’s role in the downfall of Oden Kozuki and the oppression of Wano’s people for decades showcases his tyranny. He perpetuates a regime of fear and subjugation, employing brutal forces like the Beast Pirates. Kaido’s suicidal tendencies, stemming from his search for a worthy death, add a complex, morbid twist to his character.

Charismatic Puppet Master

Donquixote Doflamingo’s Dark Characteristics

His mastery of the Ito Ito no Mi Devil Fruit enables him to control others like puppets, used chillingly against Dressrosa’s citizens and in forcing King Riku to betray the Dressrosa kingdom. Doflamingo’s involvement in the underworld as the Joker, dealing in arms and artificial Devil Fruits, shows his far-reaching influence and moral corruption. His sadistic enjoyment of others’ suffering and twisted ideals make him a profoundly dark and compelling antagonist.

1 Marshall D. Teach

Treacherous Pirate Emperor

Marshall D. Teach’s Dark Characteristics

• Murdered crewmate for Devil Fruit
• Freed dangerous criminals to strengthen crew

Marshall D. Teach, also known as Blackbeard, is #1 on this list because he is a dark character and Emperor of the Sea known for his lofty ambitions, betrayal, and manipulation.
