TX-20 was a T-series Tactical Droid that was in charge of the Confederacy of Independent Systems' units assigned to Techno Union Emir and Foreman, Wat Tambor, during the Battle of Ryloth in the Clone Wars. He was later destroyed during the ensuing battle by revolting Twi'leks.
Droid history[]
After the Ryloth was secured for the Confederacy, TX-20 was tasked with protecting the five anti-aircraft cannons of the Twi'lek city of Nabat, and protected the Twi'lek population of the nearby city so the Republic troops wouldn't use a direct assault or bombing them in oblivion from orbit. After forcing Mace Windu's three Acclamator class assault ships away, severely damaging one in the process, he was able to calculate and anticipate several moves of Jedi General Obi-Wan Kenobi, suggesting that Kenobi would not risk the lives of people for the secret Republic slave trade.
TX-20 was later torn apart by the Twi'leks while offering no resistance, his mechanical brain being unable to cope with the sudden turn of events.
