Marlena Moreau

Marlena Moreau was a female human who lived in the 23rd century. Moreau was a Starfleet Lieutenant who served on board the USS Enterprise (NCC-1701).

Shortly after she first reported on board the Enterprise, Captain James T. Kirk, Doctor Leonard McCoy, Lieutenant Commander Montgomery Scott, and Lieutenant Uhura had been involved in a transporter accident which resulted in their being transposed with counterparts from a mirror universe. While in the mirror universe, they met that universe's counterpart of Moreau, who saved their lives.

After returning to the primary universe, the four of them met Moreau when she came to the bridge to deliver a report to Captain Kirk for his signature. Spock remarked that Kirk's reaction was one of recognition, and Kirk replied that he had never met her before, but that he thought the two of them could become friends. (TOS episode Mirror, Mirror).
