Power Progression

Background and History

Kaido went to war at fifteen and fought a country alone at seventeen. At nineteen, he was captured and imprisoned on Punk Hazard, where the World Government wanted to study the source of his strength. Lin Yuan freed him from a Seastone cell and persuaded him to join by promising opportunities to fight powerful opponents 11.

Before his capture, Kaido served as an apprentice on the Rocks Pirates. He later returned to Pirate Island with Lin Yuan to retrieve belongings, including an old photograph 11 16.

Appearance

Kaido is exceptionally tall and heavily muscular, standing a head taller than Bullet. He has long hair, dark yellow eyes and a rough, beastlike voice 11.

• His full azure dragon form is over thirty meters long, with azure scales, a golden-scaled belly, curved horns and wings spanning over twenty meters 45.
• His hybrid form combines dragon features—including scales, wings, claws and a tail—with a humanoid body 87.

Personality

Kaido relishes combat and grows impatient when opponents fail to challenge him. He initially preferred charging into fights and relying on his toughness, but accepted Zephyr’s training after Lin Yuan pointed out weaknesses in his reactions and Haki control 17 45 61.

He enjoys meat and liquor, laughs loudly, and frequently bickers with Bullet. Despite his appetite for destruction, he followed Lin Yuan’s order not to harm civilians during the attack on the Bison Pirates 17 45 73.

Abilities and Skills

Physical Strength and Durability

Kaido’s Oni physique gives him immense strength and resistance to ordinary weapons. Bullets flattened against his skin, while bayonets bent on contact 29 35 55.

Fish-Fish Fruit, Model: Azure Dragon

• Dragon Breath: Fires a powerful blast of flame; one attack set all three Bison Pirate ships ablaze 45.
• Flight and defense: His dragon form has wings and scales strong enough to break the Bison captain’s Haki-coated blade without being scratched. Lin Yuan estimated his flight speed at over one hundred knots 45.
• Awakening: Restored stamina and helped regrow damaged scales during the battle with Orochi. Full-power use initially caused severe exhaustion 84 86.
• Lightning: In awakened hybrid form, Kaido trained to contain lightning around his arm and draw released power back into his body 87.
• Limit: Lin Yuan assessed Kaido’s dragon-form control as poor, making his attacks likely to affect the surrounding area 45.

Haki

Kaido uses Armament, Observation and Conqueror’s Haki 15 45 62.

• Armament Haki: He can harden his entire body and coat attacks. His Haki initially penetrated Kuma’s Paw-Paw Fruit defense during training 15 26.
• Observation Haki: Zephyr assigned him sensing drills to address his slow reactions; Kaido had previously used this Haki less often than Armament 62.
• Conqueror’s Haki: Its release knocked out over half the Bison Pirates. He later coated his iron club with it against Saint Mars 45 112.
• Ryuo: Under Ashura Doji, he practiced releasing his rigid Armament Haki as a flowing mist rather than keeping it hardened around his body 87.

• Fish-Fish Fruit, Model: Azure Dragon — The Devil Fruit he ate after the God Valley incident 42.
