Overview of the Beast Pirates
The Beast Pirates were one of the most feared pirate crews in the world, commanded by Kaido, the self-proclaimed World's Strongest Creature. For over two decades, they occupied the country of Wano, transforming it into a weapons-manufacturing fortress and building the largest zoan-based army in One Piece history. The crew's name reflects their animal theme — nearly every member wielded either a genuine zoan Devil Fruit or an artificial SMILE fruit, giving the crew an army of beast-powered soldiers.
The Beast Pirates' structure was a rigid hierarchy built entirely on strength. At the top was Kaido, an unstoppable force who could not be killed despite numerous executions. Below him were his three All-Stars, each commanding a fleet. Beneath them were the Tobi Roppo, six elite Headliners powerful enough to challenge the All-Stars. The Headliners formed the officer corps, Gifters were SMILE users with partial animal powers, and the Pleasures and Waiters made up the lower ranks. The crew numbered in the thousands, making it one of the largest pirate organizations ever assembled.
The crew's primary base was Onigashima, Kaido's floating island skull fortress off the coast of Wano. From there, Kaido coordinated his operations: weapons production, SMILE distribution, and alliances with other underworld figures. The Beast Pirates' downfall came during the Wano arc when Luffy and the alliance of samurai, pirates, and Minks launched a full-scale invasion of Onigashima. In the climactic battle, Luffy defeated Kaido, and the Beast Pirates crumbled.
Kaido — Governor-General of the Beast Pirates
Kaido was a monster among monsters. Standing over twenty feet tall with muscles like boulders, he possessed the Uo Uo no Mi Model: Seiryu, a mythical zoan that allowed him to transform into an Azure Dragon. This transformation granted him flight, fire-breathing, cloud manipulation, and scales so tough that conventional attacks literally bounced off his skin. Combined with his mastery of all three Haki types, including advanced Conqueror's Haki Infusion, Kaido was the closest thing to an invincible force in the One Piece world.
Kaido's history is one of constant warfare. As a child, he was drafted into the Vodka Kingdom's military, which sparked his lifelong hatred of authority. He joined Rocks D. Xebec's crew as an apprentice, survived the God Valley Incident, and later formed his own crew. Over the decades, he was captured by the Marines 18 times, sentenced to death 40 times, and survived 9 massive naval defeats. Nothing could kill him — not execution, not torture, not battle. He eventually settled in Wano, using its isolated geography and skilled artisans to build his power base.
Despite his brutality, Kaido had a complex personality. He respected strength above all else, regardless of allegiance. He saw Luffy's potential and was genuinely disappointed when Luffy died temporarily during their battle. Kaido's ultimate goal was not mere conquest but to create the greatest war the world had ever seen — a war that would reshape the world order. In this sense, his alliance with Big Mom and his aggressive stockpiling of weapons were all building toward a final, apocalyptic conflict that never came to pass.
The All-Stars — King, Queen, and Jack
The All-Stars were the three strongest commanders of the Beast Pirates, each wielding an ancient zoan Devil Fruit that gave them the power of a prehistoric creature. King the Wildfire was Kaido's right hand and the strongest commander. He possessed the Ryu Ryu no Mi Model: Pteranodon, allowing him to transform into a massive pterosaur with wings that could create devastating firestorms. King fought Zoro in the Onigashima raid and pushed him to his absolute limit, forcing Zoro to awaken Conqueror's Haki Infusion through Enma to win.
Queen the Plague was the Beast Pirates' chief scientist and second All-Star. His Ryu Ryu no Mi Model: Brachiosaurus turned him into a massive sauropod, but Queen was far more dangerous for his intellect than his strength. He created the Mummy virus, the Ice Oni plague, and various mechanical enhancements. Queen's battle against Sanji on Onigashima forced Sanji to accept his Germa exoskeleton, which dramatically increased his durability and speed. Queen's combination of zoan durability, scientific weapons, and mechanical enhancements made him a versatile threat.
Jack the Drought was the youngest and most direct of the All-Stars. His Ryu Ryu no Mi Model: Mammoth gave him enormous strength and durability. Jack's reputation was built on his willingness to destroy anything in his path — he attacked the Mink tribe on Zou without provocation, fought the Duke and the Cat for five days straight, and survived being sunk by Zunisha. Jack's sheer tenacity made him a terror, even if he lacked the strategic brilliance of King or Queen. He was defeated by a combined effort of the Minks and Sulong forms.
The Tobi Roppo
The Tobi Roppo were the six strongest Headliners below the All-Stars, each commanding their own crew and fleet. Who's-Who was a former Cipher Pol agent who gained the Ryu Ryu no Mi Model: Saber Tiger. His knowledge of the World Government's secrets and his hatred of Jinbe made him one of the most dangerous Tobi Roppo members. He was also the one who revealed crucial information about the Gomu Gomu no Mi's true name to Jinbe, a revelation that changed the understanding of Luffy's Devil Fruit.
Sasaki commanded the armored division and wielded the Ryu Ryu no Mi Model: Triceratops. His massive frame and heavy armor made him a frontline juggernaut. Ulti and Page One were siblings who operated as a team. Ulti's Ryu Ryu no Mi Model: Pachycephalosaurus gave her incredible headbutt attacks, while Page One's Ryu Ryu no Mi Model: Spinosaurus provided speed and mobility. Ulti's fierce loyalty to Kaido and her ability to briefly stand up to Big Mom showcased her potential. Black Maria ran the pleasure district with her Rosi Rosi no Mi spider powers, and X Drake was secretly a Marine SWORD captain working as a deep-cover agent within the Beast Pirates.
The Tobi Roppo were given a special mission by Kaido: find his son Yamato, who had been confined on Onigashima. This mission was a test — any Tobi Roppo member who succeeded would earn the right to challenge an All-Star position. This internal competition kept the officers sharp and ambitious, always striving to climb the hierarchy through strength.
The SMILE Factory and Gifters
The Beast Pirates' unique advantage was their access to SMILE artificial Devil Fruits, produced by Kaido's alliance with Donquixote Doflamingo and underworld broker Caesar Clown. The SMILE factory in Wano produced thousands of these fruits, which were fed to the crew's lower-ranking members to create an army of partial zoan users called Gifters. Each Gifter gained a permanent animal body part and could partially transform into their assigned animal, though the transformations were incomplete compared to real zoan fruits.
The SMILE fruits had a critical flaw: a 90% failure rate. Those who ate a failed SMILE lost the ability to express negative emotions — they could only laugh, permanently and uncontrollably, regardless of their actual emotional state. This tragic side effect created one of the saddest visual themes of the Wano arc: thousands of people forced to laugh through fear, pain, and despair, unable to express what they truly felt. The failed SMILE users were called Pleasures, and they formed the bulk of the Beast Pirates' rank-and-file soldiers.
Beyond the Gifters and Pleasures, the Beast Pirates employed Numbers — giant artificial humans created through genetic experiments using Big Mom's lineage factor technology. These hulking monsters stood over 30 feet tall and possessed incredible strength, though their intelligence was limited. The Numbers were deployed as living weapons during the Onigashima raid, where they were neutralized by the combined efforts of the Straw Hats' allies.
The Wano Occupation
The Beast Pirates' occupation of Wano lasted over 20 years and fundamentally transformed the isolated country. Kaido took control of Wano's government, installing the shogun Kurozumi Orochi as a puppet ruler while Kaido pulled the strings from Onigashima. The country's resources were directed toward weapons production: Wano's skilled swordsmiths and craftsmen were forced to produce armaments for Kaido's war machine. The country's borders remained closed, preventing anyone from leaving or entering without Kaido's permission.
The occupation devastated Wano's population. The people of the flower capital lived in relative comfort while the rest of the country starved. Factories polluted the land and water, turning the once-beautiful country into an industrial wasteland. The Yakuza were outlawed, and anyone who resisted was either killed or sent to the Udon Prison labor camp. The people endured 20 years of suffering, waiting for the day when Kozuki Momonosuke would return to lead them to freedom.
The liberation of Wano was the culmination of years of preparation. The Nine Red Scabbards — the retainers of Kozuki Oden — infiltrated the country. The Straw Hat Pirates, Heart Pirates, and Kid Pirates formed an alliance. The Minks of Zou brought their army. And the people of Wano themselves rose up, inspired by Luffy's determination. The battle of Onigashima became the largest conflict in the series since Marineford, and its outcome reshaped the power balance of the New World.
Legacy and Aftermath
With Kaido's defeat, the Beast Pirates ceased to exist as a coherent organization. King and Queen were captured by the Marines. The remaining Headliners and Gifters scattered, their loyalty to Kaido ended with his fall. The SMILE factory was destroyed, ending the production of artificial Devil Fruits. Wano opened its borders, and the country began the long process of recovery from two decades of industrial exploitation.
The power vacuum left by the Beast Pirates' collapse was immediately filled by other forces. The Marines moved to secure Wano's borders. The remaining Yonko scrambled to claim territories that had been under Kaido's protection. The Kid Pirates and Heart Pirates, now free from their alliance with the Straw Hats, resumed their own journeys. The Straw Hats themselves emerged from Wano with vastly increased bounties and reputation, ready to take on the final challenges of the New World.
The Beast Pirates left a complicated legacy. They were brutal oppressors who caused immense suffering, but they also demonstrated the limits of rule by fear alone. Kaido's philosophy — that only strength matters — ultimately failed because he could not inspire loyalty beyond fear. The crew's collapse showed that an organization built entirely on coercion cannot survive the defeat of its leader. In this sense, the Beast Pirates represent the dying order of the old era, replaced by a new generation of pirates who lead through inspiration rather than terror.
