Elizabeth Xander was a prominent Poseidon scientist, serving as the conglomerate's Chief Technician of New Technology. Her celebrated career focused on groundbreaking brain trauma research conducted within Poseidon's Halcon Laboratories division. Her work took a controversial turn when Halcon initiated clandestine mind control experiments, aiming to unify humanity by erasing individuality—perceived as the root of conflict. Poseidon terminated the project after Xander's death in an orchestrated accident.

Her body was recovered and covertly resurrected as a cyborg. In this transformed state, she became the central component of the Halcon system, repurposed to control individuals linked to Olympus's widely adopted Connexus neural interface—a device projecting holographic data over users' eyes. The system utilized her modified form to broadcast a mind-controlling signal, compelling affected individuals against their will.

Under Dr. Kestner and the Halcon virus's control, her cybernetically enhanced body served as the physical conduit for the unifying signal. This transmission hijacked Connexus users' nervous systems, turning them into instruments of mass riot and chaos targeting Olympus.

During the confrontation at the Halcon control fortress, an antidote temporarily suppressed the virus within her. This brief clarity allowed her to consciously override the Halcon signal, freeing the enthralled populace. Recognizing the risk of the virus regaining control, she directed her liberators to terminate her existence to prevent further manipulation. Her physical destruction caused the Halcon control system's collapse.
