The most noticeable difference is the full white coat open at the bottom instead of the original black jacket. On the front of the coat is Z's Jolly Roger. The head is partially covered by a mechanical plaque. The right eye is bionic. PX-Z also has light green hair, instead of the black hair shared by other Pacifistas and Bartholomew Kuma.
Due to being Pacifista, they do not have any personality.
Abilities and Powers
Their abilities and powers shown are identical to the classic Pacifista models, bearing Kizaru's laser beam that are fired from their mouths and their palms. While they seem to share the same scanner eyes that the prototype Pacifista have, their armor is questionable, as Franky was able to punch them down with his exoskeleton suit, and completely vaporize them with his laser.
One Piece Film: Z
During the fight between the Neo Marines and Straw Hat Pirates on Piriodo island, Z's army released the PX-Z to fight the pirates. Franky briefly fights them with the General Franky, when he destroys several of them, and later easily defeats the rest of them with his Radical Beam.
- Shirokuma (白熊 Shirokuma?) is Japanese for "polar bear", and is a type of frozen dessert.
