Yeoman Zahra was a female Human Starfleet enlisted crewmember in the 23rd century. She served in the operations division aboard the USS Enterprise in 2267 under the command of Captain James T. Kirk, during the historic five-year mission.
That same year, Zahra participated in the landing party to the surface of Deneva investigating the mysterious loss of contact between the Deneva colony and the Federation. Along with the rest of the landing party, she came under attack by the mysterious extragalactic flying parasites which had invaded the colony, although she was able to escape unharmed. (TOS: "Operation -- Annihilate!")
Zahra was played by model/actress Maurishka.
The episode's 2nd revised final draft script gave her full name as Zahra Jamal.
According to IMDb.com, her first name was Ellen.
In the novelization of Operation -- Annihilate!, her name was spelled Zahara.
IDW Publishing's Star Trek: Ongoing comic series set in the alternate reality linked Zahra (β) to the unnamed platinum-haired bridge crewmember seen in Star Trek Into Darkness, and featured her as a recurring character. Like her counterpart, she participated in the Deneva mission. She held the rank of lieutenant, and was an accomplished pilot.
