Background and History

Kaido's Wano-based crew

The Beasts Pirates were originally led by Kaido and based at Onigashima in Wano Country. They fielded thousands of pirates against Kozuki Oden and the Nine Red Scabbards during the conflict for Wano. 19

Ian became central to the crew while still a child. By age eight, he had become Wano's ruler and was already considered, alongside Yamato, part of the Beasts Pirates' future. 12 38 Under his administration, Wano's samurai class was eliminated through a sword-confiscation decree, while land enclosure displaced farmers into towns, factories, and mines. 41 Workers in Beasts Pirates-controlled factories and mines were described as being treated like slaves. 35

Wano was remade into the crew's industrial center. Mining, steel, manufacturing, construction, and weapons production expanded rapidly; surplus weapons were eventually sold overseas through contacts such as Umit. 39 41 Despite the social upheaval, Wano remained broadly stable, and later visitors described it as modern and prosperous. 41 94

Expansion and modernization

The crew expanded outward from Wano by annexing nearby islands, offering its flag to willing territories and using force against those that resisted. Its campaigns combined bombers, fierce beasts, and the Fish-Man Unit, while airports were built across controlled islands to sustain overseas air operations. 120

By this period, the headquarters alone exceeded 50,000 personnel, while the Fish-Man Unit exceeded 10,000 members; the crew's total strength approached 100,000. 120 The Beasts Pirates also gained vassals and allied forces, including Amazon Lily, Fish-Man Island's Sun Pirates, and the Vinsmoke Family. 85 108 197

The staged split and reunification

World Government efforts to exploit Ian's rising prestige created public expectations that he would challenge Kaido for leadership. Nearly half of the pirates on Onigashima chose Ian's side during a staged internal war between the master and disciple. 132 179

The split produced two geographically separate factions: Kaido's Wano-based force and Ian's Hachinosu-based force. Ian departed with more than 10,000 followers to garrison and develop the Hachinosu region. 182 183

The division ended when Ian defeated Kaido decisively. Kaido accepted the result and passed the captaincy to his disciple, reuniting every major faction of the crew under Ian. 260 261

Conquest of the New World

After repelling the World Government's all-out operation, the Beasts Pirates forced the Government to abandon the New World. Ian then ordered the occupation of the entire sea, with King advancing from Wano and Solemn and Bear leading a second force through former Whitebeard territory. 271 272

Over the following years, the crew established bases throughout the New World, absorbed capable surrendering pirates, and purged those who resisted or were deemed unworthy. The region became heavily controlled and notably safer from ordinary pirate activity. 288 312

• Queen developed a serum that can drive controlled beasts and Artificial Devil Fruit users berserk for further amplification. 281

Beast Legion

The Beast Legion consists of ferocious creatures captured from Ruskeina Island and other sources.

• Individual beasts were strong enough to overwhelm ordinary pirate crews and severely injure fighters such as Arlong. 117
• The legion was used alongside air strikes to repel the Sun Pirates during their attempted infiltration of Wano. 117
