Davison was a Starfleet officer who lived during the mid-23rd century. She served in the operations division aboard the USS Enterprise under Captain James T. Kirk, during a historic five-year mission that starship undertook. In 2269, Davison served as the ranking female security officer.
That year, she was ordered by Uhura to place a female security party on every transporter, when the men of the Enterprise became incapacitated by hypnotic suggestions emanating from the second planet of the Taurean system. (TAS: "The Lorelei Signal")
