CT - 7719 CT - 7719 , nicknamed " Banks , " was a clone trooper sergeant in the Grand Army of the Republic . When the Clone Wars broke out in 22 BBY , he joined millions of other clones in fighting for the Galactic Republic against the Confederacy of Independent Systems . His nickname was derived his unique skill of being able to see mathematical angles better than other clones , which resulted in an ability to " bank " blaster bolts off a surface and into his target . In the first year of the war , Banks was sent on a mission to the planet Oznek , ostensibly to shut down a battle droid factory . The mission , however , was a plot by Republic Commander Griebs Kishpaugh and Banks ' s fellow clone , Ghost , to embroil the strategic planet and its native species , the Toma , in the war and allow both men to defect to the Confederacy . Throughout the mission , Banks lost his entire squad to both enemy droids and the treachery of Ghost ; nevertheless , Banks managed to foil the plot , killing Ghost and arresting Kishpaugh . Though he was forced to face a tribunal following the mission , Banks was later reassigned under the command of Jedi General Bultar Swan . Biography . Early life . CT - 7719 was a clone trooper , bred on the planet Kamino and based upon the template of the Mandalorian bounty hunter Jango Fett , a Human . When the Clone Wars broke out in the year 22 BBY , he was one of millions of clones who made up the Galactic Republic ' s Grand Army , his armor painted with the standard green designs for his rank . CT - 7719 was trained to be an officer in the army and was assigned the rank of sergeant . During his training on Kamino , the trooper commanded seventy - two successful training missions . At some point , he realized that he had a knack for mathematics and angles , being able to both calculate and see better than most clones . He used this ability to calculate angles to bank his blaster bolts off objects , allowing them to hit their targets without losing their strength . The skill earned him the nickname " Banks " before he had even gone on his first mission . Mission to Oznek . Later in 22 BBY , Banks was selected by Republic Commander Griebs Kishpaugh to lead a mission to the planet Oznek , a world that was considered vital to holding the surrounding sector . He and his squad were to find their assigned drop point and investigate the Separatist presence on the planet , particularly the existence of a supposed droid command center . Although the sergeant was a " shinie " — the clone troopers ' derogatory term for those yet to fight on the battlefield — he was placed in charge of a squad of seasoned clones . The squad flew over the forests of Oznek aboard an Low Altitude Assault Transport on their seemingly routine reconnaissance mission . En route , two of the clones under his command , Syke and Ghost , questioned his methods and experience , causing him to become irate . Shortly thereafter , the squad ' s gunship came under heavy fire . The area was supposed to be unoccupied by Confederate forces , but they discovered a large droid army , which blasted them out of the sky . Despite the pilot ' s best efforts , the LAAT crashed , killing several other clones on impact . Syke escaped from the wreckage via a hatch , only to find hundreds of B1 and B2 battle droids bearing down on them . Banks and his men fought off the attacking battle droids while trying to protect their wounded . Eventually , the waves of droids ceased , and Banks covered the tracks of the surviving seven clones by detonating a thermal detonator . As they set up camp in the woods , Syke attempted to repair and use a communications array , to no avail . At the urging of Syke and Crazy Legs , their wounded pilot , Banks demonstrated the origin of his nickname to the group , ricocheting a blaster bolt and knocking a food container out of Crazy Legs ' s hand . They were then contacted via holoprojector by Commander Kishpaugh after Syke managed to get the array working . Kishpaugh informed them that the droid command center was twenty kilometers away ; they were to investigate and , if possible , disable it despite their losses , within eighteen hours . He then ordered the rest of the clone troopers from the shelter in order to speak with Banks alone . Kishpaugh inquired after Banks ' s experience with the other clones and told him it would only get worse . He told the Sergeant that he trusted he would be an unfeeling and undiluted clone , able to commit to the mission to the letter . Moreover , the mission was to be " off the books , " so the clones had to be careful not to be caught . Banks and the others moved out before sunrise , leaving Crazy Legs behind to tend to his leg , which had been broken in the crash . They moved through the forest , encountering dangerous terrain and creatures everywhere , and lost another clone , who was eaten by a large animal . As they traveled , Syke told a war story about how his armor was damaged early in the war when he destroyed two droidekas . Syke then asked Ghost for a story of his own , but the older clone demurred . Banks pointed out that they could all ask for their armor to be repaired , or even receive new armor . Syke , however , believed that a clone ' s armor was a way of telling a unique and individual story , and asked Banks why they would ever want to throw that away . Cutter , the clone trooper leading the way , brought the others ' attention to an ancient city in ruins . The clones remarked that their scanner s had not picked up any trace of the large settlement , and they suddenly found themselves surrounded and captured by Toma , the native sentient species of Oznek . With their hands bound , Banks lied , telling the Toma patrol leader that his men were on a humanitarian mission . The Toma saw through the ruse , pointing out that the troopers were carrying explosives , not medicine . The patrol leader ordered their executions , but the clones were discovered and attacked by droids once again . Upon Banks ' s request , the Toma leader cut the clones ' bonds so they could fight together . The Sergeant and the others held back the droids , but Cutter urged Banks to break off with Ghost and Syke , leaving Cutter and the others to hold back the droids while allowing Banks to complete the mission within the allotted time frame . Banks disliked the plan , unwilling to leave Cutter behind , but Cutter pointed out that their presence could not be revealed , so the Toma could not be allowed to live either . As the fight raged on behind them , Banks and the others fled . They traveled to the facility that Kishpaugh had targeted , where Ghost sniped the two Toma guards outside , allowing the clones to sneak inside . They made their way through the corridors , encountering little resistance — a fact that Banks later determined should have seemed suspicious . Once inside the main section of the facility , Banks ordered Syke and Ghost to spread out and look for signs of Separatist technology . Syke quickly noticed that something was awry , and that the facility did not look anything like how they had been told it would . Banks was shocked when Ghost shot Syke in the back , killing him . Ghost began to set bombs around the facility , nonchalantly telling Banks that Syke had to die because he did not know of their true orders : to destroy the facility , which was not a droid command center at all , but rather a power plant , which would then draw Oznek into the Clone Wars on the side of the CIS . Although Banks attempted to reason with Ghost — arguing that they should help to stop conflicts , not incite them — Ghost whirled around and fired his blaster rifle at Banks , saying that he did not need him after all . As Banks dodged the blast , the blaster bolt grazed his visor . He then attempted to shoot Ghost using his ability to ricochet blaster bolts , but the elder clone had already slipped out of sight . The Sergeant wanted to know why Ghost would betray his training and brothers , asking if his mind had gone defective from age , but Ghost told him that he had merely gained clarity and no longer wished to die . Attempting to catch him by surprise , Banks sneaked up on Ghost , but the older clone was ready and threw a grenade , which detonated right in front of the Sergeant . Battered and wounded , the Sergeant was still alive , but Ghost was not willing to let him survive . As he explained that their sabotage would drive Oznek right into the arms of the Separatists , he climbed atop Banks and pulled a garrote from his gauntlet to choke the Sergeant . Struggling , Banks managed to reach his own blaster , and fired a bolt that ricocheted around the room ' s turbines and slammed into the back of Ghost ' s head , killing him . Rushing , Banks deactivated Ghost ' s bombs and stole his helmet , escaping before the facility ' s Toma guards could catch up to him . Donning the dead clone ' s helmet , Banks contacted Kishpaugh and claimed that the mission had been completed . Kishpaugh picked him up in a shuttle , but he immediately realized the clone was not Ghost and pulled a blaster on the imposter . As they left the planet , making for hyperspace , Kishpaugh forced Banks to show his face and was surprised to find out that he had survived . The Sergeant demanded to know why Kishpaugh and Ghost had betrayed the Republic . Angry , the Commander told him that he had never wanted to fight in a galactic battle , while Ghost had simply wanted to live . Banks advanced on Kishpaugh and told him to surrender , but he refused , noting that the clone had no weapon . The Sergeant then threw Ghost ' s helmet at Kishpaugh , smashing his hand backward and forcing his blaster to fire , destroying his own pilot droid . Banks tackled the Commander and , after a crash landing , turned him over to Republic custody . Aftermath and reassignment . Banks , scarred from the battle and locked in binders , faced a military tribunal for his actions , where he told the whole story of the mission . His superiors reprimanded him for following Kishpaugh ' s orders , saying that the Republic ' s standing on Oznek had become damaged . However , they also noted that his clear - headed actions and bravery had prevented an even worse disaster and likely saved thousands of lives , so they could not punish him . Instead of commending him for his actions , he was reassigned — two weeks later , he was on a snow - covered planet serving under Jedi General Bultar Swan . Because of the combat he had seen and the clones he had met , Banks ended up with three long scars covering his face — and he decided to leave unrepaired the damage Ghost had done to his helmet . Aboard an LAAT / i gunship en route to combat Separatist droids , he asked General Swan to no longer use his clone designation and to instead refer to him as Banks . Personality and traits . As a clone of Jango Fett , Clone Sergeant Banks was physically identical to both the bounty hunter and the millions of his clone brethren . He was born with fair skin , brown eyes , and black hair , which later appeared brown . Also like Fett , he grew to a height of 1 . 83 meters . As a clone fresh out of his training on Kamino , Banks strictly adhered to the regulations set forth for clone troopers , including keeping his hair short and his armor and weapons clean . Banks possessed an ability to calculate mathematical angles . He could use this ability to shoot blaster bolts off objects in order to ricochet them into a target . Although at first he believed that the trick was of little use outside of the barracks , it saved his life when Ghost tried to murder him on Oznek , as he was still able to calculate the angles and fire his blaster while being strangled . Banks originally did not like having the clones under his command use his nickname , nor did he appreciate their humor . En route to their mission , when Banks pulled off his helmet to clean it , Syke mocked him for his adherence to what Syke regarded as foolish regulations . Banks did not intend to suffer insolence at all and admonished Syke , informing him of the proper regulations and threatening him with being forced to write an in - depth report on regulation protocols . When Ghost asked Banks if he had ever been in the field and faced enemy fire before , Banks admitted that he had not , but tried to defend himself by stating his spotless record during training missions . Over the course of the mission on Oznek , Banks ' s outlook drastically changed . The one clone in his squad whom he admonished the most , Syke , ended up having the most influence on him , as Banks adopted his outlook on being a clone and an individual at the same time . During his fight with Ghost , Banks suffered wounds to his face and ended up bearing three long scars across his features . He also adopted the common clone practices of preferring his individualized nickname and retaining the damage done to his armor . Like most other clones in the beginning of the Clone Wars , Banks possessed Phase I battle armor , painted green to signify his rank as a sergeant . During the mission to Oznek , he used both a pair of DC - 17 hand blasters and , later , a DC - 15S carbine . Behind the scenes .
