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 neural parasites which had invaded the colony, although she was able to escape unharmed. (TOS: "Operation -- Annihilate!")
