Biography
Early life
Tula was the daughter of Kal Chenka and his wife and sister to Liv. Whilst Tula believed that Liv was the favourite child, Liv always felt that Tula was and later found it impossible to live up to her. Tula greatly looked up to her father, calling him her hero. (AUDIO: Escape from Kaldor)
As a child, she sometimes called her sister "Livvie", which she hated. (AUDIO: Love Me Not) She had a number of unreliable boyfriends. (AUDIO: The Robots of Life)
Career at the Company
Early career
Tula began a career at the Kaldor City Company. Seeking to prove herself, she rarely visited her family and missed a number of her father's, mother's and sister's birthdays. Eventually, she learnt that her father did not approve of her work and chose not to return home nor call, incorrectly believing that he hated robots.
Due to her dedication to her career, she 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 Company business. Although she paid the expenses, she did not attend the funeral, causing friction between herself and Liv, and they stopped speaking to each other. Whilst Liv believed that Tula had forgotten about her father, Tula believed that she had said goodbye to her father in her own way. (AUDIO: Escape from Kaldor) She also paid for a state-of-the-art headstone. (AUDIO: The Robots of Life)
Tula became an overtech with the 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) She built and programmed robots and believed that she understood them and was also aware of their use to "purify" the complex of sand rats. She was familiar with the redacted incident files and read her sister's debrief of the events aboard the Lorelei. (AUDIO: Escape from Kaldor)
Robot attacks
The Eighth Doctor visited Tula, who gave him a demonstration of SV111 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 that she had read about in the files concerning Storm Mine 4 and the Lorelei and took him to Galla Posca.
Having the voice of the Super-Vocs and technology able to pass herself off as one, she sneaked into the complex to free the humans there, bumping into Liv, Helen Sinclair and Kit Laver on the way. Tula and Liv discussed their father and came to an understanding, with Tula finally apologising for never having returned home. After the robots were restored by the Doctor and Lina Hadway, Tula believed that the matter should not be covered up. Posca, however, disagreed.
Tula offered Lina a job at the Company but was refused. She then asked SV23 to track down Liv using the Kaldor Bionetwork, but it was unable to find her as she was in the TARDIS. (AUDIO: Escape from Kaldor) Liv joined her shortly after. (AUDIO: The Robots of Life)
Year with Liv
A week after Liv moved in with Tula, the two visited their father's grave. After Liv was denied a job at Kaldor City Hospital, Tula pulled some strings to have the need for a Ward Hygiene Certificate removed, leading to her being hired. She got on the wrong side of her new boss, Overseer Skellen, after Liv convinced her to look into the Company's recording of dead people's memories using his access code. Whilst he did not want to fire her, he put a permanent warning for misconduct on her record. However, Liv blackmailed Skellen with a recording of SV57 displaying sentience, causing him to remove it. (AUDIO: The Robots of Life)
Personality
Tula had something of an ego, which she believed was inevitable for one involved with the creation of artificial intelligence. She left her family in order to prove herself to her father, who she had always considered to be her hero, and was upset when she learnt that he did not approve of her work.
Despite being loyal to the company, she disagreed with Posca and believed that the people deserved to know about the robot attacks. (AUDIO: Escape from Kaldor)
After a difficult day at work, Tula liked to relax by watching Beat the Super-Voc. She also enjoyed drinking wine. (AUDIO: The Robots of Life)
