RVN-73

RVN-73, affectionately known as Arven, was an android from the 28th century. It had artificial intelligence. Arven was manufactured by a company named Villiers Artificial Life, and served as assisant to Professor Gradius before she was killed by the Squall. At the conclusion of Paradox Lost, the Doctor brought Arven back to London in 1920, allowing him to remain with Professor Angelchrist. (NSA: Paradox Lost)
