|~ TX-21 informing Poggle the Lesser of his foundry's production.|
TX-21 is a T-series Tactical Droid of the Separatist Droid Army serving under Poggle the Lesser and the secondary antagonist of the Star Wars: The Clone Wars episode "Weapons Factory", though he also makes appearances in the episodes "Landing at Point Rain and "Legacy of Terror".
TX-21's droid factories became a target of the Republic forces, not only because of their high output of droids but because they were producing new ray-shielded "Super Tanks" for the Confederacy.
As Republic forces advanced on the foundry, TX-21 was granted permission by Poggle the Lesser to deploy the new Super Tanks against the Republic. After Jedi Padawans Ahsoka Tano and Barriss Offee breached the foundry's security and attempted to destroy the foundry's generator, TX-21 and Poggle the Lesser took a Super Tank to go confront the two.
In the ensuing fight, Ahsoka Tano tossed a detonator onto the Super Tank. As TX-21 laughed that the detonator would do nothing to damage the tank, the explosive device detonated and destroyed him.
