Umbara

This Besalisk Jedi is all about getting results and, indeed, his battlefield record lists many key victories in the Clone Wars. He has an unshakable confidence in his methods, and he will brook no insubordination among his charges. In personal combat, he can be ferocious -- his giant arms carry two double-ended lightsabers, making him extremely dangerous in close quarters. Pong Krell's reputation as a successful general is well known but so is the fact that the casualty rates of the clone troopers under his command are the highest.

Rex once served the Republic on the frontlines during the Clone Wars, taking orders from Anakin Skywalker and Ahsoka Tano as first a captain and later a commander. He viewed military service as an honor, and his loyalty to the Republic and his Jedi Generals was absolute. But when Order 66 was executed, it was Ahsoka who helped to free Rex from the programming of his inhibitor chip. At the dawn of the Empire, Rex has escaped with his life but is considered killed-in-action in the eyes of the new regime. That allows him to operate in the shadows and help any clone brothers who remain separate from the Imperial ranks.

At the time of their introduction, the Republic clone troopers represented the future of galactic warfare. Far superior to battle droids, the clone troopers formed the backbone of the Republic's new military that waged war against the forces of the Confederacy of Independent Systems. So symbolic were they of the times, the galaxy-wide conflict that saw their debut took its name from their ranks: the Clone Wars.

For over a thousand years, the Galactic Republic stood firm as a democratic union that governed the galaxy. The Republic was governed by the Galactic Senate, consisting of elected officials from each system and world, and Jedi Knights served as peacekeepers. With the rise of Supreme Chancellor Palpatine, however, the Galactic Republic -- and democracy -- would crumble.
