A T-series tactical droid with feminine programming was in the service of Count Dooku.
After Dooku's Gungan spy, Minister Rish Loo took control of Gungan Boss Lyonie's mind and the army, the tactical droid went with Gen. Grievous to attack the Naboo with the Gungan army. The Tactical Droid and his battle droids inquired why Lyonie, who was actually Republic Represenative Binks posing as him, inquireed as to why the gungans were cancelling their attack. The tactical droid then led Lyonie and a Gungan General Tarpals to Grievous. Apparently, Grievous saw through the trick and tried to kill Binks but got himself captured after he killed Tarpals. At the same time, Skywalker was captured by Dooku and a few Magnaguards while chasing Rish Loo. The tactical droid was present when an exchange of both hostages took place. She threw Skywalker's lightsaber back at him and left the planet with Grievous.
