Fifth Tamasan

Tamasan was the pilot of Ollistra's Battle TARDIS.

She took Ollistra to get the Eighth Doctor on a jungle planet. She was a member of the Third Patrex Battalion. After Ollistra met with the Doctor, she arrested Bliss, Rupa Maguire, and Quarren Maguire. (AUDIO: Echoes of War)

She wanted to get the Celestial Intervention Agency involved in decontaminating the prisoners, but Ollistra didn't want to get them involved. She was in her third incarnation by the time she met the Doctor and had been fighting on the front line for 120 years. She was to be promoted if her next mission was successful and train the Doctor for war. She was the main trainer for his troop. When the Daleks attacked, she led the battle and told the Doctor where Bliss was. (AUDIO: The Conscript)

Tamasan later regenerated and met the Doctor and Bliss again. (AUDIO: The Lords of Terror)
