Anti - trooper Anti - troopers composed the last generation of clone soldiers based entirely on the genetically - modified template of Jango Fett , a bounty hunter who served as the progenitor of the Republic clone troopers . At the end of the Clone Wars , which coincided with the Republic ' s transition into the Galactic Empire in 19 BBY , the Imperial Military seized control of Kamino , the original source of clones for the Grand Army of the Republic , and coerced the planet ' s native race to continue manufacturing more clone stormtrooper s for the Empire . The loss of self - rule bred resentment against the Empire among Kamino ' s scientists and led some to form an underground resistance movement . Over the next decade , the renegade Clone Master s built a new army of Fett clones , mostly composed of anti - troopers with a complement of " Rail " - class Advanced Recon Commandos . When the conspiracy was discovered in 12 BBY , the Sith Lord Darth Vader deployed the 501st Legion to Kamino with orders to suppress the Kaminoans ' fledgling rebellion , thus resulting in a battle between two sides entirely composed of Jango Fett ' s progeny . The anti - troopers made their first and last stand against the Empire and were subsequently annihilated by the Imperial stormtroopers of the 501st . History . Origin . In the final year of the Clone Wars , Prime Minister Lama Su of Kamino and Supreme Chancellor Palpatine of the Galactic Republic had a falling out ; Kamino had been the prime source of the Republic army ' s clone troopers until the Chancellor commissioned new cloning facilities on Coruscant and Centax - 2 . Utilizing Spaarti technology , new generations of Fett would be fully developed within one year as opposed to ten years . Rather than use Kaminoan scientists to oversee the new cloning centers , the Chancellor entrusted the Spaarti - grown clones to Arkanian Microtechnologies . Unknown to Chancellor Palpatine , however , Lama Su did not hand over all of the clone troopers to the Republic . When the Clone Wars ended in 19 BBY , the Republic had been transformed into the Galactic Empire , the Jedi Order was betrayed and almost completely exterminated , and Chancellor Palpatine declared himself emperor of the galaxy . The Republic clone troopers , programmed with absolute loyalty to the Chancellor , were re - designated as Imperial stormtroopers . Soon afterward , Kamino found itself under the Empire ' s military occupation ; the Kaminoans own creations had commandeered the cloning facilities to ensure that they continued to produce more clone stormtrooper s for the Empire . Disillusioned with Palpatine and resentful of the Imperial presence on their world , a splinter faction of Kaminoan Clone Master s initiated a clandestine operation to build a new clone army — one loyal to Kamino instead of the Empire . Both intellectually advanced and speedily grown within the Tipoca City Cloning Facility , the Anti - Imperial clone troopers — otherwise known as " Anti - troopers " — were engineered over the span of nearly a decade through Kamino ' s state of the art cloning technology . Like the original clone troopers that served in the Clone Wars , the entire army of Anti - troopers were based on the genetic template of the late bounty hunter Jango Fett . The Kaminoan Clone Masters also secretly commissioned a special forces unit of Rail - class ARC troopers to compliment the Anti - troopers and add to the strength of Kamino ' s growing army of rebel Fett clones . To ensure that the Anti - troopers were superior to their older clone brothers , they were all trained as jet troopers and were provided with limited flight jetpacks in addition to their Phase I clone trooper armor . They were also trained to be both expert snipers and infantry soldiers , and were thus equipped with DC - 15x sniper rifles and DC - 15A blaster rifle s , both of which were used by the original clone troopers during the Clone Wars . After nearly ten years of Imperial occupation , Kamino ' s new clone army had reached the completion of its development and were ready to launch their " " Clone Rebellion " " in order to liberate Kamino from the Galactic Empire . Their full allegiance belonged to their Kaminoan creators , and thus they were perfectly willing to fight the Empire and kill their Imperial brethren . When the Empire discovered the Kaminoans ' plot in 12 BBY , the 501st Legion was ordered to bring Kamino back into the Imperial fold by annihilating its rebel clone army . Leading the 501st was the bounty hunter Boba Fett , the only unique clone of Jango Fett . The Battle of Kamino . The Kamino uprising commenced with Boba Fett leading the stormtroopers of the 501st Legion in an effort to infiltrate Tipoca City . Their first objective was to secure a canister that contained Jango Fett ' s genetic material , mainly to ensure that it was not damaged or lost during the battle . The Anti - troopers immediately engaged their Imperial brothers in combat , and though they were willing to fight to the death , they ultimately failed to prevent Fett and the 501st from getting inside of the cloning facility . With Jango Fett ' s DNA secured , Boba Fett immediately returned to a secured platform where an Imperial shuttle transported the canister off - planet , thus ensuring that the Empire would have the resource required to engineer more Fett clones in the future . Meanwhile , the Anti - troopers continued to engage the 501st Legion on the city ' s numerous platforms . But , unable to gain an advantage or turn the tide of battle , they steadily lost more and more ground to the relentless push of the 501st stormtroopers . After securing more ground on the platforms , the 501st proceeded to infiltrate the inner workings of the cloning facility with the objective of destroying the life - support system consoles that kept undeveloped rebel clones alive , thus preventing the Kaminoan rebels from cloning more Anti - troopers . Along the way , however , the Rail - class ARC troopers emerged and began attacking the 501st . But despite their best efforts , the 501st was still able to enter the city and destroy the life - support systems and abort the developing rebel clones . With the battle lost and their homeworld on the verge of falling completely under the Empire ' s control , the Kaminoan Clone Masters attempted to retreat by utilizing a pair of LAAT gunships to evacuate Tipoca City . The last of the Rail - class ARC troopers joined with the remaining Anti - troopers outside of the city . Together , they made their last stand on Tipoca City ' s platforms in a fight to death in order to buy their creators enough time to escape . Their sacrifice was ultimately in vain , however , and the 501st was able to destroy the gunships before they took off , and thus they killed the Kaminoans who created the rebel clone army . The end of the Clone Rebellion saw every last Anti - trooper and Rail - class ARC trooper massacred down to the last clone . Tipoca City , every other Kaminoan cloning facility , and all of Kamino and its people became fully subjugated to the Galactic Empire . Aftermath . The failure of the Anti - troopers had severe consequences not only for Kamino , but also ironically the Imperial clones of Jango Fett as well . With Kamino under full Imperial rule , the Kaminoan race was forced to continue its service to the Empire by engineering countless clone stormtroopers . In addition to the Kaminoan scientists , Imperial Human scientists were brought in to oversee the growth of Imperial clone soldiers as well . Although the 501st Legion proved its loyalty to the Empire once more by killing their rebel clone brothers in order to put down the Kaminoan rebellion , Emperor Palpatine ultimately decided that the ranks of the Stormtrooper Corps could no longer be the exclusive province of Jango Fett ' s progeny . Even though enlisted personnel had long since become part of the overall Imperial Military , including the Army and Navy , the Fett clones took pride in the fact that they alone served as the Emperor ' s stormtroopers , just as they had done so for the Republic as clone troopers . The thought of serving alongside clones that were based on different templates , or even enlisted stormtroopers , was appalling to the proud clones of Jango Fett . Nevertheless , their programmed loyalty to the Emperor prevented them from displaying their dismay in any way , thus forcing them to watch as the Stormtrooper Corps became increasingly diverse . Ultimately , Fett ' s clones were reduced to the status of a small minority and became lost in a sea of non - Fett clones and enlisted soldiers . While the 501st Legion remained pure of outsiders for a time , none of Jango Fett ' s clones ever became used to the idea of fighting alongside the soldiers they mockingly dubbed as " " the new guys " . " Roughly a decade later , the resentment only grew worse , especially for the few remaining veterans of the Clone Wars . By the year 2 BBY , Commander Cody was in charge of the Imperial garrison of Kamino , most of which was composed of enlisted troopers . Having watched the obvious decline in the Imperial Army ' s operational effectiveness ever since the Empire increased its pool of stormtrooper recruits , Cody developed an intense hatred for all stormtroopers that were not clones of Jango Fett . He regarded them as expendable idiots with no sense of themselves or their surroundings , and would have happily traded them all for just one real clone trooper . Behind the scenes . Although the Anti troopers wear Phase I clone trooper armor in " " , two troopers seated in the turrets of the LAAT gunships on the " Kamino Uprising " level are wearing Phase II clone trooper armor . After the battle ' s conclusion , Boba Fett left Kamino , mentioning that he was going to Tatooine to track down a smuggler , obviously referring to Han Solo .
