Xoanon
Xoanon was a supercomputer that was designed to guide the Mordee expedition. It developed into a living creature and became the most powerful computer ever built. It became insane and turned into a god to the humans whose development guided it.
Form
Xoanon existed within the main computer complex called the “Sacred Heart”. This room was composed of several screens with a podium in the middle which held a hexagonal screen that flashed as it spoke. The only face it ever projected was that of the 4th Doctor.
Abilities
Xoanon was able to watch and control various parts of the Mordee ship through sensory links. Besides controlling the environmental conditions of the ship, he could electrify the walls or throw the atomic generators into overload. He could project a beam of white light to harm individuals and psychically control them.
The computer could also create phantoms that were psi-tri projections of Xenon’s face. These hunted by movement or sound and could crush their targets easily.
