Rex Farrel
From Tardis Wiki, the free Doctor Who reference
Rex Farrel was the son of John Farrel and Mrs Farrel. He took over as manager of Farrel Plastics after his father retired. The Master took control of him as part of his scheme to bring the Nestenes to Earth. After being defeated, the Master had Farrel disguised as himself and used him as a decoy to escape, leaving him to be shot and killed by Captain Mike Yates when he pulled out a gun. (TV: Terror of the Autons)
When Ferrel took over the industry, he spent most of its capital on machinery to replace handwork, disregarding the advice of his father's chief engineer, McDermott. Ferrel was very obediant to his father throughout all of his life and felt dominated by him. This made him more susceptible to the Master's hypnotizing techniches.
