A near-omnipotent entity from another dimensional plane (resembling an interdimensional Rura Penthe in appearance as well as climate), 0 (Zero) was discovered by Q. Q had requested of the Guardian of Forever to be shown "something new, something different." Upon this request, the Guardian displayed various images and events, Q picking one at random. 0 was attributed to be the cause behind the bizarre telekinetic powers exhibited by Faal, his son Milo, and Gary Mitchell. However in a previous novel, Q-Squared, Q was alleged to be the cause of Gary Mitchell and Dr. Elizabeth Dehner's powers.
