In "Dead or Alive 4", Christie serves as Donovan's bodyguard, but they are unable to prevent the Mugen Tenshin ninja clan (Hayate, Ayane) and Ryu from destroying DOATEC's Tritower headquarters. As the tower is engulfed in flames, Christie finds Helena inside and reveals that she killed Maria. After an inconclusive fight, Christie flees the tower, while Helena is rescued from the building and becomes the new leader of the Dead or Alive tournaments. Christie goes on to continue her work as an assassin for hire, a role she resumes in "Dead or Alive Xtreme 2" (2006).
