Tula Chenka

Overtech Tula Chenka was the sister of Liv Chenka and the daughter of Kal Chenka. (AUDIO: Escape from Kaldor)

Early life
Tula was the sister of Liv Chenka, who always felt that their father, Kal, preferred Tula over her. (AUDIO: Escape from Kaldor) As a child, she sometimes called her sister "Livvie", which she hated. (AUDIO: Love Me Not)

Dedicated to her career, Tula rarely visited her family and failed to visit her father after he fell ill. At the time that he died, she was away from Kaldor on a business trip. Although she paid the expenses, she did not attend the funeral, causing friction between herself and Liv, and they stopped speaking to each other. (AUDIO: Escape from Kaldor) She also paid for a state-of-the-art headstone. (AUDIO: The Robots of Life)

Career at the Company
Tula became an overtech with the Kaldor City Company and offered her voice to the new generation of Super-Vocs, (AUDIO: Escape from Kaldor) including ones built for therapy. (AUDIO: The Robots of Life)

The Eighth Doctor visited Tula, who gave him a demonstration of Super-Voc 111 believing that he was a client. She soon learnt that he was a friend of Liv's and was intending to reunite the sisters. Initially suspicious of him after the robots began attacking, she learnt his identity as the Doctor from the redacted incident files concerning Storm Mine 4 and Lorelei and took him to Galla Posca. (AUDIO: Escape from Kaldor)

Personality
Tula had something of an ego, which she believed was inevitable for one involved with the creation of artificial intelligence. (AUDIO: Escape from Kaldor)
