Background / History

Kaido was once a low-ranking member of the Rocks Pirates while Whitebeard and BIGMOM served as division commanders. During the God Valley incident, BIGMOM obtained the Mythical Zoan Fish-Fish Fruit, Azure Dragon Form and gave it to Kaido, enabling his rise as the World's Strongest Creature. 148 149

As governor-general of the Beasts Pirates, Kaido built an organization that rewards strength over background or allegiance. He tolerated former enemies such as Ashura Doji because of their power and sought to recruit strong pirates, including Reno, Drake, Kid, and Hawkins. 52 123 598 683

Kaido maintained covert Artificial Devil Fruit transactions with Doflamingo and Caesar Clown. His 500-member Artificial Devil Fruit User Legion was central to his position as a Yonko. 150 184

After BIGMOM was killed by Reno, Kaido ordered the Beasts Pirates to search the New World for Reno. His pursuit culminated in a battle at Udon, where Reno defeated him after breaking through his defenses and overcoming his final Flame Bagua attack. 149 174 186

Reno had Kaido returned to Onigashima, later bound and imprisoned on Thriller Bark. Gecko Moria used Kaido's shadow to resurrect Demon Oz, creating an exceptionally powerful zombie. 187 192 193

Personality

He is volatile, heavily drinks rum, and frequently lashes out at subordinates when frustrated. His inability to die drives him to make repeated suicide attempts, while his failure to find Reno leaves him particularly enraged. 123 174

Story Role / Major Arcs

Search for Reno

Kaido initially considered recruiting Reno after Reno defeated Crocodile. After learning that Reno killed Garp, Kaido recognized that Reno possessed power capable of threatening him and ordered his crew to locate him. 52 123

BIGMOM's death transformed Kaido's interest into vengeance. He mobilized the Beasts Pirates' strongholds across the New World and threatened to turn the sea upside down to find Reno. 149 174

Battle of Udon

After Reno entered Wano and killed Orochi, Kaido transformed into his Azure Dragon form and flew to confront him. Kaido declared his intention to avenge BIGMOM, while Reno stated that he wanted Yamato, Wano, and Kaido himself. 179 180

Kaido fought Reno through his dragon, human-beast, and Flame Dragon forms. Reno overwhelmed him with superior Haki control, defeated Great Vajra · Thunder Bagua with Hagoku, and rendered Kaido unconscious after countering Flame Bagua. 184 186

Captivity and Demon Oz

Following his defeat, Kaido was returned to Onigashima by Jack before Reno later transported him to Thriller Bark as a prisoner. Moria implanted Kaido's shadow into Demon Oz, using it to create a zombie considered extraordinarily difficult to defeat. 187 192 193

Wano War

Kaido later returned to Onigashima after repeated defeats by peak-strength Whitebeard. When the Straw Hat Pirates and other Supernovas approached Wano, Kaido dismissed them at first, defeated Kid, Killer, and Hawkins, and attempted to recruit the survivors. 591 598 683
