The Beasts Pirates are a massive pirate organization; a roughly 20,000-strong army organized along simple yet strict hierarchical lines. Led by the Emperor Kaidou
, they are one of the four most powerful pirate crews in the world. The true strength of this crew lies in their Underworld
connections and with access to SMILEs
to help form an army of over 500 artificial Zoan Devil Fruit
users. The sheer amount of members with SMILE Devil Fruit powers was enough to overwhelm and force both the likes of Monkey D. Luffy
and Roronoa Zoro
to retreat after attempting a frontal assault on Kaidou's castle.
