Background / History

Kaido established the Beast Pirates in Wano Country shortly after Gol D. Roger's execution, intending to turn the country into the foundation of a pirate empire. Weapons being transported for the crew's expansion were stolen by Gecko Moria, provoking Kaido to wait for Moria's arrival and personally lead the response. He also maintained control over Wano through Kurozumi Orochi while allowing Kozuki Oden's public humiliation in the Flower Capital to continue. 9 21

When Moria's crew entered Wano, Kaido confronted Moria in Ringo. He initially entertained Moria's Shadow-Shadow Fruit ability, then overwhelmed him with Thunder Bagua and Conqueror's Haki. The battle changed when Lin Ye arrived after killing King; Kaido offered the young fighter the position of vice-captain, but Lin Ye refused. 24 25 26

Kaido recognized Lin Ye's Divine Departure as Roger's slash and suspected a connection between them. He escalated into his hybrid form, but Lin Ye's rapidly increasing Haki and adaptation forced Kaido into an extended battle that devastated Wano. After fighting for roughly a week, suffering a broken horn, and realizing he could not decisively defeat Lin Ye, Kaido withdrew from the battle. 27 28 35 39

Humiliated by the outcome, Kaido spent the following years repeatedly challenging Marines and famous pirates to train himself. He rebuilt his crew on Onigashima, trained the children there as future Beast Pirate officers, and fixated on surpassing Lin Ye. 41 89 90 120

Kaido later sailed to Amazon Lily for a rematch. Despite his fully awakened power and Thunder Dragon form, Lin Ye defeated him in less than half an hour. Kaido refused Lin Ye's demand for submission, and Charlotte Linlin intervened in the conflict on his side. 121 123 125 126

During the alliance's counterattack against the World Government's Voidbringers, Kaido led the Beast Pirates against the southern deployment point on Sosa Island. Even after the Dragon Lock sealed his transformation and the Voidbringer suppressed Devil Fruit users, he defeated Cipher Pol Aigis Zero's forces, destroyed the Voidbringer control center, and ordered Sosa Island destroyed to prevent its reconstruction. 143 151 152

Appearance

Kaido is an enormous, burly man whose size and presence intimidate even his own subordinates. He is frequently seen drinking from a massive sake gourd while carrying his signature spiked club. 9 22 24

• Bloodshot crimson eyes when enraged or intoxicated. 9 22
• Carries a massive spiked club as his primary weapon. 22 24
• Can transform into a gigantic Eastern dragon that blots out the sun. 151
• His hybrid form develops dragon scales and a thick dragon tail. 27
• One of his horns was broken during his first prolonged battle with Lin Ye. 35

Personality

Kaido is volatile, violent, and easily angered by insults or perceived challenges to his authority. Moria's theft of a cargo ship was enough for him to prepare a direct assault, while news of Lin Ye's growing strength repeatedly drove him into furious outbursts. 9 22 89

Despite his brutish reputation and drinking habit, Kaido is calculating. He sought to expand the Beast Pirates' military strength in Wano, delegated investigations to King when appropriate, and attempted to recruit Lin Ye rather than immediately kill a potentially valuable fighter. 9 21 26 29

He respects strength, persistence, and the willingness to fight directly. Lin Ye's refusal to submit impressed him enough that he offered recruitment more than once, while his own defeat became an obsession that pushed him through years of training. 26 29 120 123

Abilities & Skills

Mythical Zoan: Fish-Fish Fruit, Azure Dragon Form

Kaido possesses an awakened Mythical Zoan Devil Fruit that grants dragon and hybrid transformations, extraordinary durability, and control over weather-related forces. 27 33 120

• Hybrid form — Enhances his speed, strength, defense, and vitality with scales and draconic traits. 27
• Azure Dragon form — Allows aerial movement, flame breath, lightning attacks, and weather manipulation. 29 30 33 151
• Thunder Dragon form — His strongest awakened form, developed through years of training specifically for his rematch with Lin Ye. 123
• Limit — The Dragon Lock can temporarily seal his transformation ability, forcing him back into human form. 151

Physical Strength and Durability

Kaido's body is extraordinarily resilient, with rapid recovery, overwhelming physical force, and internal durability capable of resisting advanced Armament Haki attacks. His vitality is central to his reputation as the strongest creature. 26 27 29

• Recovered from Lin Ye's Roger-style slash quickly enough for the wound to begin healing almost immediately. 27
• Withstood internal attacks that visibly dented his scaled chest and drew blood. 29
• Continued fighting after being forcibly stripped of his dragon form and suppressed by a Voidbringer. 151 152
• Destroyed the Voidbringer control center with a single club strike while covered in blood. 152

Haki

Kaido is a powerful user of Conqueror's Haki and Armament Haki, capable of coating his club and attacks with both forms simultaneously. 24 27 29

• His Conqueror's Haki can knock out large numbers of nearby pirates. 24
• Clashes of his Conqueror's Haki with Lin Ye's tore apart thunderclouds and devastated Wano's terrain. 27 29
• Uses Armament Haki to defend against attacks, including Moria's Haki-coated blade. 24
• Infuses attacks with Conqueror's Haki to produce black lightning and immense shockwaves. 24 27 30

Thunder Bagua

Kaido's signature club technique combines overwhelming speed, lightning, and Haki.

• Thunder Bagua — Defeated Moria with a direct strike and sent him flying from the battlefield. 24
• Great Virtue: Thunder Bagua — A faster, more powerful version that struck Lin Ye despite his heightened Haki. 27 28
• Falling Three Worlds: Ragnarok — A two-handed lightning-and-Haki strike that drove Lin Ye into the ground and fractured the terrain. 28

Thunder Dragon Annihilation Flash

Kaido's strongest documented attack, created over years of obsessive training to defeat Lin Ye. In Thunder Dragon form, he turns into a lightning bolt moving beyond the tracking ability of ordinary Observation Haki. 123

Close-Quarters Combat

Kaido remains a devastating combatant even without his Devil Fruit transformations. 151 152

• Frenzied Demon Ten Fists — Ten consecutive strikes, each stated to be capable of crushing a small fortress. 152
• Defeated multiple Cipher Pol Aigis Zero agents with his club while encircled and injured. 151 152
• His combat experience allowed him to identify Lin Ye's lack of battle-hardened adaptability during their first duel. 28

• Spiked club — Kaido's primary weapon, used with Armament and Conqueror's Haki. 22 24
• Massive sake gourd — Constantly carried and used for drinking. 9 21 120

Relationships
