Memory Beta, non-canon Star Trek Wiki

Sadira, also known as Lisa Bates, was a 23rd century Human woman. She served in Starfleet as a captain's yeoman aboard the Federation starship USS Enterprise in the 2260s under the command of Captain James T. Kirk. She was also a Major in the Tal Shiar, and her time in Starfleet was an undercover assignment.


Early life

Sadira was the daughter of Terran prisoners taken captive by the Romulan Star Empire in the Earth-Romulan War. She was born in captivity, and was raised from birth to be fully loyal to the Romulan Praetor. (TOS - Legacies novel: Captain to Captain)

She rose through the ranks of the Tal Shiar, ultimately reaching the rank of Major. The Romulans put her in a model human settlement on Romulus, where she spent years developing the skills and mannerisms required for her new Starfleet alias, Lisa Bates. (TOS - Legacies novel: Best Defense)

Lisa Bates alias

The Tal Shiar instructed her to join Starfleet, which she did as her alias 'Lisa Bates'. Her ultimate posting was as a captain's yeoman to the USS Enterprise (NCC-1701). In this role, she discreetly gathered intelligence for the Tal Shiar and planted listening devices throughout the ship. In 2267, Sadira learned of the existence of the Transfer Key from the listening devices she planted in Captain Kirk's quarters. After Kirk retrieved the Transfer Key from Number One and hid it in a secret panel, she stole it, and teleported herself and the key to the Romulan ship waiting nearby, the ChR Velibor. (TOS - Legacies novel: Captain to Captain)

ChR Velibor assignment

Sadira instructed the chief engineer of the Velibor, Ranimir, to merge the Transfer Key with the Velibor's main power core. Her orders were to disrupt the Federation and Klingon Empire peace conference on Centaurus. While the ship was cloaked, Sadira used the Transfer Key to send key members of each delegation to the Jatohr universe, which almost led to a skirmish between the Klingons and the Federation. Captain Kirk convinced the Klingons to work with the Federation, and used a method of sensor triangulation to find her ship, rendering the cloak ineffective. Each usage of the Transfer Key damaged the Velibor, and Sadira's zealous use of the key ultimately caused multiple failures in the ship's sub-systems.

With the Velibor nearly inoperable, Sadira ordered the crew to enable the self-destruct sequence, so as to prevent the Transfer Key from falling into Federation hands. She was killed by Centurion Julius Mirat right before the ship self-destructed, as payback for her callous disregard of the ship and the traditional chain-of-command. (TOS - Legacies novel: Best Defense)


"I confess I'm not going to miss this rather demeaning outfit, nor playing the servile yeoman, but both served their purpose."
Sadira, 2267[src]
