Andron (The Eternal Present)

Andron was chief of Mar-Kom's time police in 3550 New Britain. He tracked the Doctor's return to 1971 England and posed as a police constable to capture him. He piloted the TARDIS to New Britian and imprisoned the Doctor with Theophilus Tolliver. In preparation for their execution, he demonstrated to them the power of Markon's killing machine, and allowed them access to a laboratory to prepare weapons to fight the machine. When the Doctor and Theo destroyed the machine, Mar-Kom struck down Andron. (TVC: The Eternal Present)
