In 2269, Davison was the ranking female in the security department. 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 planetTaurus II. (TAS: "The Lorelei Signal")
Nichelle Nichols provided the voice for Davison. The character was not seen, but it seems possible that Davison was one of several unnamed security lieutenants who transported down with Uhura and Christine Chapel's landing party to rescue Kirk, Spock, McCoy and Carver. Despite the fact that Davison is not physically shown in the episode itself, the novelization of "The Lorelei Signal" does feature her physical appearance, describing the character as "a middle-aged, efficient-looking woman."
