The Beasts Pirates were the crew occupying Wano Country. Kaido served as the crew's founder and governor-general. The Beasts Pirates effectively operated as the muscle to secure Shogun Kurozumi Orochi's power over the land. However, Kaido had personal goals of expansion, wanting to ultimately overthrow the World Government in a war after acquiring superior military might. To this end, he forcibly subjugated a number of powerful pirates and their crews, for the sake of bolstering his own power. As a result, his crew consisted of a diverse number of pirates, including some species of pirate that were seldom found elsewhere.
