Background / History

Kaido was once a member of the Rocks Pirates and acted as a mentor-like figure to the young Roa, teaching him about the world. Even in his youth, Kaido was exceptionally fast and eager to rush into major battles. 17

Following the Rocks Pirates’ collapse, Kaido formed the Beasts Pirates. Six years after losing contact with Roa, he sought him out and attempted to recruit him, believing their combined strength could surpass the Rocks Pirates at their peak. Roa refused, leading to a clash that established both Kaido’s superior Haki at the time and Roa’s rapidly closing gap. 28 29

Kaido later accepted Roa’s help after being imprisoned by the Marines. Roa rescued him, and Kaido’s crew offered treasure and two Ancient Zoan Devil Fruits as payment. During the rescue, Roa also brought Abel into his own organization. 42 47

In Wano, Kaido fought Kozuki Oden and joined Roa in overthrowing the Kozuki regime. With Kurozumi Orochi installed as puppet Shogun, Kaido and Roa ruled the country, industrialized it, and violently suppressed the Anti-Kaido samurai resistance. 53 56 57

Although Roa repeatedly outpaced him, Kaido continued to seek duels as a way to measure the widening difference in their strength. He eventually accepted Roa’s proposal to unite major pirates, expel the Marines from the New World, and divide its territory among themselves. 149 150

After Roa’s twenty-five-year disappearance, Kaido became one of the era’s three strongest pirates and a Pirate Emperor. Upon Roa’s return, he reunited with him and continued fighting beside the revived alliance against the World Government. 260 262

Appearance

Kaido is a colossal combatant whose most recognizable form is an immense azure dragon, described as hundreds to over a thousand meters long. 27 148 305

• Azure scales, flowing mane, long whiskers, sharp horns, claws, and fangs in dragon form. 27 305
• Can assume a muscular dragon-man form with darker scales and enhanced physical power. 149
• Often carries a sake gourd and a heavy spiked iron club. 91 149
• His enhanced body possesses scales layered over a tough exoskeleton. 305

Personality

Kaido is intensely battle-driven and measures people primarily by their strength. He welcomes difficult opponents, becomes excited when faced with powerful enemies, and repeatedly challenges Roa despite knowing he is outmatched. 150 209 305

He holds openly social-Darwinist views, believing that the strong should trample the weak. This outlook shaped his indifference toward Wano’s suffering and his contempt for opponents he considers unworthy. 31 209

Despite his bluntness and arrogance, Kaido is not simply reckless. Roa considers him smarter than he appears and capable of schemes and careful judgment. He also recognizes strength in others, respects Roa’s growth, and readily cooperates with him when their ambitions align. 42 46 150

Kaido is frequently drunk, and alcohol directly influences his fighting style. His drunken states can shift his demeanor dramatically while preserving the ferocity of his attacks. 91
