I have been wondering....on the force unleashed how is that robot proxy able to use the force? Also how is he even able to pull a lightsaber(or two when maris) when fighting Galen? Does he pull it out of his ass? Then how is he even able to use it so profficiently?
PROXY cannot use the Force, and he uses lightsabers due to programming based off data taken from holos of Kenobi, Windu, Yoda, Vader, etc, and data from the 7 lightsaber forms. In the book, PROXY's mission is to kill Starkiller, and not only does Galen know this, he encourages it. PROXY takes on the image of Obi-Wan in the beginning of the book, as well as Kenobi's mastery of Soresu. However, it states that the only difference between the robot and the man is the robot's inability to use the Force, but instead can make highly sophisticated calculations based off previous fights with Galen. At least, that is how the book describes it. I haven't played the game, but have been told by people who have played the game and read the book you don't get to fight PROXY. I could be mistaken. I highly recommend reading the book, it was very, very difficult to put down.
He could always use Magnets built into the Sabers, and use that to pull it back to him.
