Lieutenant Marlena Moreau in 2267.
In the mirror universe, Lieutenant Marlena Moreau was a scientist serving aboard the ISS Enterprise in 2267. She was also James T. Kirk's captain's woman.
When she saw her captain show mercy to his enemies, Moreau deduced that Kirk was in fact not her own captain, but instead a counterpart from a different universe (our own). Along with Spock, she helped Kirk and his other crew escape from the Enterprise before they could be discovered and killed. (TOS: "Mirror, Mirror")
- Like her counterpart, Moreau was portrayed by Barbara Luna.
