A T-series military strategic analysis and tactics droid designated TJ-912, possessing feminine programming, served the Confederacy of Independent Systems during the period known as the Clone Wars. During the Battle of Sullust, this tactical droid commanded a Recusant-class light destroyer within a fleet under the leadership of Separatist Commander Asajj Ventress. In the midst of the conflict, Count Dooku, the Separatist leader, contacted the droid, instructing it to eliminate the Separatist command ship on which Ventress was present. These orders came after Darth Sidious, Dooku's master, instructed him to kill Ventress. TJ-912 followed these instructions and destroyed the cruiser, unaware that Ventress had successfully escaped the ship.
TJ-912, a T-series military strategic analysis and tactics droid with feminine-programmed attributes, was constructed by Baktoid Combat Automata. She was a member of the naval forces belonging to the Confederacy of Independent Systems throughout the Clone Wars, fighting against the Galactic Republic. During the Battle of Sullust in 20 BBY, TJ-912 held the position of commanding officer on a Recusant-class light destroyer, which was part of a larger fleet commanded by Asajj Ventress, a Separatist commander and Sith apprentice. Ventress piloted her Ginivex-class fanblade starfighter in this engagement. Obi-Wan Kenobi, a Jedi Master, and Anakin Skywalker, a Jedi Knight, engaged Ventress in fighter craft, which resulted in all three pilots landing in the main hangar of the Separatist command ship. There, they engaged in a lightsaber_duel using their lightsabers.
As the duel continued, Count Dooku, the Separatist leader and master of Ventress, contacted TJ-912. Darth Sidious, Dooku's own master, had instructed Dooku to eliminate Ventress to test his loyalty to the Dark Lord of the Sith. TJ-912 gave Dooku Ventress's location and then received the order to destroy the Separatist flagship from the Count. The tactical droid pointed out that doing so would destroy their own forces, as well as Ventress and the Jedi, but Dooku confirmed that was the intention. TJ-912 then ordered her own destroyer to fire upon the command ship once they were in the correct position.
As the command ship took heavy damage, TJ-912 made contact with a Hyena-class Droid Bomber and told it to crash into the hangar where the Jedi and Ventress were battling. The craft exploded upon hitting the hangar wall, causing Ventress, Kenobi, and Skywalker to return to their respective fighters and flee the [ship](/article/starship] immediately before the cruiser was completely destroyed. TJ-912 informed Dooku that the ship was destroyed and, because the tactical droid did not know that Ventress and the Jedi had escaped, that scans showed no survivors. Dooku, believing her task was complete, ordered TJ-912 to recall the fleet, which the droid acknowledged.
TJ-912, a tactical droid of the T-series, was programmed with feminine characteristics and stood at a height of 1.93 meters. Her plating was colored tan and red, and her sensors were yellow. Although she initially questioned Dooku's order to destroy their own command ship, citing the potential harm to their own forces, TJ-912 swiftly complied once the Count confirmed his awareness of the situation.
TJ-912 made her debut in "Nightsisters," the twelfth episode of Star Wars: The Clone Wars' third season, which was broadcast on January 7, 2011. Cara Pifko provided the voice for the droid, and she also voiced the character Naa'leth in the same episode. TJ-912's final line in the episode, "By your command," is a reference to a phrase commonly spoken by the Cylons in the Battlestar Galactica series. An unnamed tactical droid that appears in "Shadow Warrior" from The Clone Wars' fourth season uses the same color scheme as TJ-912.
