For the prime universe counterpart, please see Alex.
Alex was an Imperial Starfleet engineer, stationed on board the ISS Enterprise in 2155. He was apparently killed when the ship was destroyed by the Tholians in the Vintaak system. (ENT: "In a Mirror, Darkly")
Mirror Alex, like his counterpart, was played by background actor Mark Correy.
