Biography . During the Clone Wars , this T - series tactical droid served in the Separatist Droid Army , and in 22 BBY , he attracted the attention of Jedi General Aayla Secura . Wanting to obtain the data held in the memory banks of the tactical droid ' s cranial unit , Secura planned an ambush to acquire the head of the droid . With her clone troopers , she set a trap by fabricating an information bunker in a rocky canyon on a planet . Eventually , the tactical droid learned about the bunker , and , hoping to receive valuable information about the Grand Army of the Republic , he led his droid forces to capture it . By the time the tactical droid arrived at the bunker with his forces , Secura had hidden herself inside of it , and positioned her clone troopers on a nearby rock formation , where they prepared to ambush the droid forces . As a B2 super battle droid exploded the door of the bunker , the tactical droid ordered his data retrieval droids to gather all of the information held in the data banks inside it . The droids , however , informed the tactical droid that the data banks were completely empty . This revelation confused the tactical droid , and at that moment , the Republic clone troopers launched their attack . Under heavy fire , the tactical droid panicked , ordering his droid forces to defend him while he fled inside the bunker and left his cohorts to be destroyed by the clone troopers . Inside the bunker , the droid stated that he was too valuable to be destroyed , but was suddenly confronted by Secura . Before the surprised droid could trigger cyberostasis to protect his memory banks , Secura quickly decapitated the tactical droid with her lightsaber . The Jedi then took the droid ' s unscathed head , preparing to transfer the cranial unit to her cruiser and analyze it with a robolobotomy . Characteristics . Manufactured by Baktoid Combat Automata , this droid , like all tactical droids , was 1 . 93 meters tall and was far more intelligent than standard battle droids of the Separatist Droid Army . His freedom from being controlled by a central control computer allowed him to think and function independently . The droid had masculine programming and white photoreceptors . The droid was very impatient and eager to gain information about his enemies . An information bunker , which the droid believed to contain Republic intelligence , proved to be too tempting a target for him to resist . He was often dissatisfied with his subordinates ' activity , insulting the droids under his command while ordering them to march more swiftly and , later , to protect him . The tactical droid also believed himself to be more valuable than his troops — too much so to be destroyed . When Secura ' s trap was revealed , the tactical droid panicked and was not able to trigger cyberostasis in time to protect his memory . Behind the scenes . This droid marked the debut of the tactical droids , and made his first and only appearance in the " " , which took place before the episode " Jedi Crash " of the .
