Innocents of Ryloth
TX-20 went down to Ryloth and served Emir Tambor by holding the people of the city Nabat hostage. When Obi-Wan Kenobi and his troops arrived, he used the Twi'leks as a living shield. Obi-Wan was therefore unable to attack and the tactical droid sent out probes to find out all about his plans and think out a strategy to defeat him. He assured Tambor via hologram that he would defeat Kenobi. However, the Jedi outwitted him, and a huge fight began in which Kenobi freed the Twi'leks, but TX-20 pointed an AAT at him. The droid, thinking he had won, laughed evilly, until the free Twi'leks climbed onto the tank and tore him apart in their rage.
- In "Innocents of Ryloth," when TX-20 pointed the barrel of the AAT at Kenobi, he states "You lose, General Kenobi," a phrase General Grievous said to Kenobi on Utapau.
