|~ TX-20 to Wat Tambor.|
TX-20 is a T-series Tactical Droid serving as a commander of the Separatist Droid Army forces on Ryloth and the primary antagonist of the Star Wars: The Clone Wars episode "Innocents of Ryloth". He also makes an appearance in the episode "Supply Lines".
TX-20 informed Count Dooku that the Republic had sent Senator Bail Organa to negotiate a treaty allowing them to resupply the forces of Jedi Master Ima-Gun Di in their garrison on Ryloth.
"Innocents of Ryloth"
An army of droid forces under the command of TX-20 captured the Ryloth city of Nabat. Setting up base camp there, TX-20 enslaved the city's residents and used them as shields around the proton cannons he had set up.
After the blockade around Ryloth was destroyed, TX-20 was ordered by Wat Tambor to use his proton cannons to shoot down any Republic troops trying to land. However, some Republic gunships managed to slip through and land their troops, which included Jedi Master Obi-Wan Kenobi and clone Commander Cody.
TX-20 decided to launch a final attack against Commander Cody's troops. He was later informed that Kenobi was freeing his prisoners, prompting him to divert his attention away from the battle. Pointing the barrel of his tank's cannon at Kenobi, he laughed at the Jedi. However, his amusement was short lived as his former prisoners climbed aboard his tank and tore him apart while he shouted "does not compute" over and over.
