Bartholomew Kuma

Bartholomew Kuma is an recurring antagonist that appears in the One Piece series. He is a cyborg that is one of the seven Warlords of the Sea and a fomer member of the Revolutionary Army. After the events of the Sabaody Archipelago Arc, he has been modified into a full Pacifista (human weapon) and completely follows under the World Government's orders.

Personality
Before the modifications, Kuma was a very calm character that tends to not get surprised by anything. Despite working for the World Government, he willingly helped the Straw Hat Pirates escape with their lives but this is mainly due to Luffy being the son of Dragon. Even before being modified, Kuma remained emotionless. After the modifications were done to him, Kuma completely loses his free will and does what the World Government tells him to do. Because of this, he is no longer an ally to the Straw Hat Pirates.

Powers and Abilities
Kuma ate the Nikyu Nikyu no Mi (Paw-Paw Fruit) that allows him to repel anything with the palms of his hands. This Devil Fruit is very formidable as it can deflect almost any attack (including sword slashes), air, and even pain itself. Kuma can also use this Devil Fruit power to send people away to where he chooses.

As a Pacifista, Kuma is able to fire light beams from his mouth. He is also very durable and is capable of take a lot of attacks without showing much damage unlike other Pacifistas. Also, despite his large size, Kuma is able to move very fast even faster than Luffy's Gear Second speed. By using his Devil Fruit powers on himself, Kuma is also able to teleport from one place to another.
