Information
Affiliated Fifth Doctor
Species Tracer

Abby, originally named Amy, is a fictional character played by Ciara Janson in a series of audio plays produced by Big Finish Productions based on the long-running British science fiction television series Doctor Who. A human "tracer", a device designed to track down the segments of the Key to Time, she is a companion of the Fifth Doctor.

After her travels with the Doctor, Abby, alongside her sister Zara, would return in their own audio series, Graceless.

The character first appears in The Judgement of Isskar, in which the Fifth Doctor is brought to a rainy planet where he finds a compass which leads him to Amy, then just a few minutes old and not yet having a name. Telling him that the compass was a segment of the Key to Time, she asks if he could help her collect two more segments. She turns the segment into its original form and puts it into a satchel leading to another universe.

Arriving on Mars in the distant past, and after the Doctor decides to name the tracer "Amy" (thinking she had agreed upon the name), Amy realises that the segment of the Key is disguised as a capstone on the pyramid in the town. The Doctor and Amy are arrested and taken to Magistrate Isskar, accused of being thieves by Isskar's beadles. They are let go with a warning not to approach the pyramid. Understanding but disobeying the warning, inside the pyramid, the Doctor and Amy meet another tracer, a "sister" of Amy, who already had one of the segments of the Key in her possession, along with her assistant in her quest, Harmonious 14 Zink. After agreeing to the Doctor's suggestion of naming her "Zara" ("just to shut you up"), Zara turns the segment back into a crystal, which causes massive and disastrous changes to Mars's environment. Zara leaves with the segment using Zink's time ring. The Doctor, Amy and Zink jump on board an approaching ship, and the Doctor pilots it to safety. Unable to help the catastrophe inflicted on Mars, the Doctor and Amy leave in the TARDIS for their next destination.
