Victoria first appears in the 1967 serial The Evil of the Daleks. She is the daughter of scientist Edward Waterfield (played by John Bailey), who in 1866 is experimenting with time travel and has attracted the attention of the Daleks. In order to assure Waterfield's collaboration with their capture of the Doctor and their experiments with the Human and Dalek Factors, the Daleks with the help of Theodore Maxtable took Victoria as a prisoner. To measure his emotional responses, they then manipulated Jamie McCrimmon into rescuing, although they ultimately re-captured her and took her to Skaro'. At the conclusion of the adventure, Waterfield is killed saving the Doctor's life, and asks him to take care of Victoria. The Doctor and Jamie take her in as part of the TARDIS crew.
On the outside, Victoria is a typically fragile lady of her era, frequently screaming when faced with the creatures the Doctor and his companions encounter in their travels, such as the Cybermen and the Yeti, the latter which are automatons of the disembodied Great Intelligence. However, this exterior hides an inner strength that crops up when needed. Victoria may be young, but she has an instinct for when she is being lied to, and her sensibility is a contrast to the recklessness of Jamie and the curiosity of the Doctor. Jamie, in particular, is very protective towards and fond of Victoria, and is heartbroken when she chooses to leave.
Despite being a good match to her two companions, Victoria eventually finds herself unsuited to extended travel with the Doctor. At the conclusion of the serial Fury from the Deep, she decides to leave the TARDIS, settling with a family named Harris in the 20th century. Her subsequent life is not shown in the television series. She is mentioned, but not seen to be travelling with the Second Doctor in the 1985 serial The Two Doctors.
