The computer programmed replica of Losira was a defensive measure used by Kalandans on a Kalandan outpost discovered by the USS Enterprise in 2268. When the Enterprise's landing party arrived on the planet, the image of Losira appeared a number of times and each time killed a member of the crew by touching them. The victim would die from cellular disruption. She appeared in main engineering and fused the matter/anti-matter bypass controls, causing a runaway condition which, uncorrected, would destroy the ship. The hologram Losira was played by actress Lee Meriwether.
