Angela Price (Rise of the Cybermen)

Angela Price was a former 9-to-5 employee of Cybus Industries. She had unwittingly discovered a file on the mainframe that she wasn't supposed to read. "Men with guns" subsequently began knocking on her doors, and was forced to spent a life on the run. She went under the alias "Mrs Moore" when she joined the Preachers. (TV: The Age of Steel) She worked as their van driver (TV: Rise of the Cybermen) and "techie". After she went on the run, Angela's husband thought she had died. Angela thought it was the only way to keep him and their children safe which she regretted. (TV: The Age of Steel)

In 2007, Angela did a protocol search on the company that stole away humans — International Electromatics. She figured out that International Electromatics was a dummy company established by Cybus to carry out the kidnappings. But she and the other Preachers didn't know the full extent of Lumic's plans.

Angela and the Tenth Doctor entered Cybus' cyber-conversion factory inside Battersea Power Station via the cooling tunnels to stop the Cybermen. The Doctor asked her about her history and she told him about her past. The Cybermen in the tunnels began to awake after the pair accidentally tripped one of the sensors, and they chased the Doctor and Angela out of the cooling tunnels. While moving through the factory, she threw an electromagnetic bomb at the Cyberman that was once Sally Phelan, and comforted Sally when she realised the bomb disabled her emotional inhibitor. After the Doctor deactivated Sally's circuitry, Angela insisted that they had to find the cancellation code of every Cyberman's inhibitor "before they kill everyone else". A Cyberman then appeared behind Angela and electrocuted her to death, infuriating the Doctor, saying that they didn't have to kill her. (TV: The Age of Steel)

The Doctor later told Jake, Angela's fellow Preacher, to find her family and tell them what she did for them. (TV: The Age of Steel)

The Doctor recalled her when Davros prompted him to remember all who had died in his name. (TV: Journey's End)
