An ambitious, ruthless proponent of military power, Tarkin became a favorite of Supreme Chancellor Palpatine and rose rapidly through the Imperial ranks. Shortly after the Empire's creation, he was put in charge of the construction of the Death Star. Tarkin saw the Death Star as a way to crush all dissent to the Empire's rule -- fear of the station's planet-killing superlaser would keep the galaxy's star systems in line. He demonstrated the station's power by destroying Alderaan, but died soon afterwards when the Death Star itself was destroyed.

Rather than use flesh-and-blood warriors, the Separatists prefer mindlessly loyal soldiers that are unquestioning of orders, and easily controlled. The soulless ranks of their battle droid armies consists of tall, thin robotic soldiers with exposed joints and bone-white or rust brown metal finishes that gives them an eerie resemblance to animated skeletons. Battle droids are very efficient, and can be controlled from centralized command centers, like the enormous Droid Control Ships used by the Trade Federation. They are dim-witted, often suffering programming glitches that give them quirky personalities that are too slow to adapt to enemies like Jedi Knights and clone troopers.
