The Pacifista (パシフィスタ, Pashifisuta) are Human Weapons (人間兵器, Ningen-heiki) developed by Navy's head scientist Dr. Vegapunk. They are cyborgs built in the mold of the . They are cyborgs built in the mold of the Warlord Bartholomew Kuma, who is a completed version for the project (despite he still keeps and maintains his free will). As stated by Sentomaru, the funds required for the construction of just one Pacifista are roughly equal to that of a Navy-issued battleship.
Sentomaru noted that after the timeskip period, PX-5 and PX-7 were outdated models from two years ago, meaning that the Pacifista project has been updated and modified.

All the Pacifista replicas seen thus far have been identical in appearance to Bartholomew Kuma, even in his uncommon body proportion. The only distinguishing features between them and the genuine article are the lack of a Bible, Kuma's gloves and his Paw-Paw Fruit palm pads. The Pacifista are built from human corpses, except for the original Kuma, who was gradually converted into a Pacifista. The Pacifista have the voice of Kuma, furthering their genuine replication to him. They all have no memories of their past lives and are under complete control of the World Government.
Their appearances are so convincing that pirates unfamiliar with the genuine article believe they are the real Kuma. The Straw Hat Pirates, having previously fought Kuma, were able to tell the difference eventually. Likewise, X Drake, a former rear admiral familiar with the project, was aware of its nature. Some New World pirates are aware of Vegapunk's experiments, and that he sent several prototypes to handle incidents in the past, but were surprised that they were all modeled after Kuma. There appears to be around twenty of them in service as of the Navyford War, though it is unknown how many have been destroyed and built since then.
