The clone troopers of the Grand Army of the Republic are fictional soldiers in the Star Wars franchise, cloned from Jango Fett, a Mandalorian bounty hunter. They first appeared in Star Wars Episode II: Attack of the Clones, and returned in Star Wars Episode III: Revenge of the Sith where they were played primarily by Temuera Morrison. In the two Clone Wars animated television series, they are voiced by Andre Sogliuzzo and Dee Bradley Baker.
Clone troopers comprised the bulk of the Army of the Republic during the Clone Wars. They are depicted as the main part of the armed forces of the Galactic Republic in its final years, becoming one of the largest armies ever assembled, only surpassed by the Separatist Droid Army. Nearing the end of the Clone Wars, through a subliminal command known as "Order 66", the Clone Troopers turned on the Jedi and slaughtered most of them. After the Clone Wars, the Clone Troopers served as the nucleus for the armed forces of the Galactic Empire, eventually becoming the first Imperial Stormtroopers. Later on the clone homeworld of Kamino, the Kaminoans made clones to fight the Imperial clones and The Empire. When the rebellion of clones was crushed The Emperor ended the cloning due to the tendency of the clones to turn on their leader. The clones were then replaced by "volunteers", but the clones that were already in the army were allowed to stay in the Imperial Army.
