Erika Benteen

Erika Benteen was a human Starfleet officer who served during the 24th century.

While at Starfleet Academy Benteen befriended Timothy Barranco, a fellow cadet. Their relationship would evolve into a romantic one. 

In 2372, Benteen served as Vice Admiral James Leyton adjutant. She was part of Leyton's conspiracy to take over the Federation and was promoted to captain and given command of the USS Lakota. Benteen attempted to stop the USS Defiant (NX-74205) from reaching Earth. However, when she was ordered to use quantum torpedoes to destroy the Defiant Benteen refused and stop down the Lakota, letting the Defiant continue its journey to Earth. 

In 2376, Benteen was in command of the Lakota during the Battle of Sol, though her rank had been reduced to commander.

At some point, Benteen served on the USS Liberty (NCC-1776) as operations manager and later as executive officer. (Star Trek: Liberty)

Alternate realities
In the Pendragon timeline, Benteen remained loyal to Leyton throughout the Federation Civil War. In the final battle of the war Benteen turned against Leyton and beamed to his flagship to try and convince him not to launch a massive attack against Earth and wipe out a large portion of the population. Benteen shot Leyton when he attempted to set off his ship's self destruct.
