Ilia

Lieutenant Ilia was navigator on the USS Enterprise during the V'Ger incident of the early 2270s. Ilia, a Deltan from the planet Delta IV, had been romantically involved with Willard Decker, who also later served aboard the Enterprise. Although Ilia was eliminated by a probe from the V'Ger entity, a mechanical near-duplicate of her was created by the probe in an attempt to communicate with the Enterprise ' s crew. The duplicate, which included both her memories and personality (though both suppressed under "her" primary programming), was so exacting a copy of the original that mission-captain Admiral James T. Kirk would later list Ilia as missing instead of killed, following her involvement in the conclusion of the crisis.
