X'Hal was primarily responsible for repelling a Psion invasion, and was therefore made the Vegans* high priestess and ruler. The Psions returned, however, killing X'Hal and experimenting on her lifeless body, eventually converting it to pure energy, which unexpectedly brought her back to life as a powerful battle goddess. Destroying the attacking Psions. she then turned her uncontrolled power against her own people, destroying three of the twenty-five Vegan worlds before she could be captured and brought under control by those who would later become the Warlords of Okaara.

Vega is saved only when X'Hal breaks free and detonates the explosives harmlessly. Raven heals the badly injured Starfire. after which Koriand'r is reunited briefly with her parents and brother before returning to Earth with her teammates.
