Why are secretaries so hot? I don't know, but Polly can give any of her secretary colleagues a run for their money. She first meets the Doctor when he and Dodo come to investigate the artificial intelligence known as WOTAN, created by Polly's employer, Professor Brett. She then helps the Doctor defeat WOTAN when the evil AI tries to, you guessed it, take over the world. With Dodo deciding to stay in 1966, Polly joins the doctor for a number of travels through time and space.
