TX - 20 / Legends TX - 20 was a T - series tactical droid that was in charge of the Confederacy of Independent Systems ' units assigned to Techno Union Emir and Foreman , Wat Tambor , during the Battle of Ryloth in the Clone Wars . Tambor ordered him to conquer the Twi ' lek city of Nabat , which he did , leading his army to complete victory and establishing a camp in the city , at the cost of many innocent Twi ' lek lives . Once the Republic debarked on Ryloth , he sent probes to spy the Republic forces . He armed himself with courage to confront the famous High General Obi - Wan Kenobi , and during the battle , he was able to predict the strategies and tactics of his enemies , and counterattacked them wisely . He established five proton cannons in the center of the city , and stopped the advance of his opponents , forcing them to hide inside the tunnels around of the city . The tactical droid starved some creatures and sent them against the Jedi , even though his initial campaign wasn ' t killing them , but causing them a lot of casualties . However , TX - 20 didn ' t count with the surprising attitude of the General , and he was forced to betray his own army when his cannons were destroyed . When he was about to kill Kenobi and Numa , the liberated Twi ' lek prisoners from his camp tore him to bits . Biography . Occupation . Shortly after the Battle of Ryloth began , TX - 20 was serving aboard Count Dooku ' s flagship . While on the cruiser , the droid informed Dooku of an impending meeting between Senator Bail Organa of Alderaan and King Katuunko of Toydaria . After hearing the news , the Count ordered Lott Dod to intervene . He was then sent to Ryloth some time later . After the planet was secured for the Confederacy , TX - 20 was tasked with protecting the five anti - aircraft cannons of the Twi ' lek city of Nabat , and used the Twi ' lek population of the nearby city as living shields to prevent the Republic troops from using a direct assault or bombing them in oblivion from orbit . After forcing Mace Windu ' s three Acclamator class assault ships away , severely damaging one in the process , he was able to calculate and anticipate several moves of Jedi General Obi - Wan Kenobi , suggesting that Kenobi would not risk the lives of prisoners and would use an unorthodox maneuver instead . To counter any move of Kenobi while preserving his own forces , TX - 20 unleashed starved gutkurrs onto Ghost Company , thinning their ranks severely . After doing this , he began to prepare for their final direct assault , computing that he now had a 742 to 1 odds of victory against the remaining Republic troops . TX - 20 ' s computations , while correct , lacked one critical factor : local aid to the clones . After rescuing the Twi ' lek girl Numa , Obi - Wan , Waxer and Boil , led by the child , used the underground sewers to sneak behind the enemy line and release the captured villagers . TX - 20 led his troops to face the Republic assault , but the clones only assaulted as a diversion to allow Kenobi to take control of one of the cannons and turned its fire on the other four . Turning around , TX - 20 destroyed Obi - Wan ' s commandeered cannon , and closed in on the downed Jedi , believing that by killing him , he could still win . He was about to finish the Jedi with his Armored Assault Tank , when , seeing their savior and Numa ( who had sneaked to the downed Obi - Wan and was attempting to drag him away ) in danger , the Twi ' lek villagers suddenly surged forward and mobbed the tank . TX - 20 was torn apart by the Twi ' leks while offering no resistance , his mechanical brain being unable to cope with the sudden turn of events . Behind the scenes . Production - wise , TX - 20 was supposed to be the first tactical droid to appear in , but later production changes pushed his appearance back . TX - 20 had the letter ' T ' Aurebesh on the left side of his torso and his head ; the T stands for T - series tactical droid . TX - 20 was voiced by Corey Burton in Innocents of Ryloth and Phil LaMarr in Supply Lines , and is the first tactical droid to be given a designation . A Hasbro action figure of TX - 20 was created and released in 2010 as part of .
