Pacifista

The Pacifista are replica cyborgs of the Shichibukai Bartholomew Kuma. Kuma himself is also a Pacifista.

Appearance
As replicas of Bartholomew Kuma, all the Pacifista seen thus far have been identical in appearance to him.

Abilities and Powers
The Pacifista are cyborgs much like Franky of the Straw Hat Pirates. They have a body made of an unknown substance tougher than steel (as Zoro couldn't cut Kuma in half), however as Franky pointed out though they are equipped with various body modifications, also like him they are still human and they are capable of bleeding. So far, only Kuma is seen capable of talking as the other Pacifista have so far remained silent (aside from the Pacifista copy attacked the Kid and Heart Pirates), aside from sounds made from fighting, such as recieving damage. As Kuma pointed out, while they are cyborgs just as Franky they are not the same as Franky.

As cyborgs, the Pacifista are capable of taking staggering amounts of damage and continue to opperate afterwards while fighting many strong foes all at once. The cyborgs are obedient and will obey any order given to them, however after a certain amount of damage they can become wild and uncontrollable.

Devil Fruit
The Pacifista are divided in abilities. The original Kuma has the powers of the Devil Fruit Nikyu Nikyu no Mi, however the other Pacifista have been noted to not display this same ability, but rather replicate the Kizaru's Devil Fruit powers instead. As pointed out by the Straw Hats, this doesn't make them any less powerful then the original Shichibukai. Kuma himself is also capable of firing a laser beam from his mouth, however he has not displayed the other Pacifista abilities.

Bartholomew Kuma the Pacifista
After Kuma witnessed Moria get beaten by Luffy, Kuma then reported this to the World Government. Fearful that the rumors of Gecko's defeat will cause another global uproar like with Crocodile, they ordered Kuma to kill all witnesses on Thriller Bark including the Straw Hat Pirates. Accepting the order, he launched an attack on some of the members of the Thriller Bark Victim's Association before shifting his attention to Zoro. Kuma weakens Zoro, and uses his Devil Fruit ability to take down Franky and Sanji. He gives them an ultimatum: let him kill Luffy, and he lets them live. When they refuse him, Kuma calmly detonates the entire island.

Though this does not succeed in killing the Straw Hats, it knocks all of them out. Just when he is about to finish an unconscious Luffy off, Zoro, in a desperate move, strikes him with a Shishi Sonson (Lion's song) in an effort to kill him by cutting him in two but is only able to damage him. The wound on Kuma's shoulder reveals that he is a Cyborg. He then reveals that he is different from Cyborg Franky. Kuma is an incomplete human weapon created by the World Government and Dr. Vegapunk, known as a Pacifista. Zoro offers to trade his life for Luffy's, seeing no other way. Kuma agrees and at that moment, Sanji decides to give his life up. Zoro promptly knocks him out, feeling necessary to sacrifice his own life rather than Sanjis'. Kuma states that he would not harm Luffy, as his "honor would be at stake", in exchange for Zoro experiencing the pain Luffy endured throughout his fight against Moria. Kuma proceeds to literally extract Luffy's pain, and directs it to Zoro, which almost kills him. Kuma then teleports to the entrance to the ship. He is last seen musing about Dragon, having a good son with a loyal crew.

The Pacifista attack!
Soon after, many other Pacifista units made their way to the Sabaody Archipelago, where one of them was able to track down and find the escaping Kid Pirates, who were running from other Marine chaos due to the actions partially caused by captain Eustass Kid. The Heart Pirates soon joined in the battle to escape the island.

Also, another Pacifista appeared in front of Urouge and in front of the Strawhats. During the recent battle, they demonstrated none of the Devil Fruit abilities the original Bartholomew Kuma had previously, firing lasers from his hands instead of using his paw fruit, and failing to counter Franky's coup de vent, despite his previous fighting style being heavily focused on reflecting air. It was X. Drake determined that these many Kumas are in fact Pacifistas, into which Vegapunk has copied Kuma's appearance and Kizaru's powers.
