Last week, Star Wars fans officially met K-2SO, the newest droid companion to a band of Rebels in the Star Wars universe. The new metal companion will be played by science fiction actor by Alan Tudyk in Rogue One: A Star Wars Story. The droid known as K-2SO is an Imperial Security Droid that abandons the Empire, joining the Rebel Alliance for as-yet-unrevealed reasons. This particular droid won't be like other popular droid companions in Star Wars, though. In fact, Rogue One's director Gareth Edwards says that he specifically made this droid to be the opposite of the classic protocol droid C3PO. K-2SO is fast and dangerous, unlike the clumsy, friendly Threepio.
