==Biography==
Orac was developed by the scientist Ensor during his exile on the planet Aristo. He was capable of tapping into and controlling any computer based around tarial cells, a key Federation component. This allowed him to seize control of the Liberator when it visited the planet. After Ensor's death, he was taken off the planet by Roj Blake and his crew. Having been programmed with Ensor's personality, he could be arrogant and condescending, and occasionally refuse to provide information he believed the crew could work out for himself. One of his first tasks was to show a projection of the future that indicated the Liberator would be destroyed. In fact, the ship in question was an identical ship working for the System, which Orac destroyed himself by jamming its missile tubes.
It soon became clear however that Orac was as vulnerable as anyone else, when he fell under the control of a telepathic entity known as the Darkness. He fatally electrocuted a girl named Hanna who tried to deactivate him and came close to crashing the Liberator in order to give the Darkness the energy to move into their dimension, but was telekinetically deactivated by Cally with help from the telepathic moon discs. Afterwards, Kerr Avon fitted him with an explosive that would detonate if the Darkness possessed him again.
Orac was a key part of Avon and Vila's plan to cheat Freedom City, being able to read the numbers of the computerised roulette wheel. After the Liberator's encounter with the Andromedan invasion fleet, Orac was briefly evacuated along with Avon. His loyalty to the crew was not total however. He took orders from Federation Commander Mori when captured by him and placed the ship at risk by failing to warn the crew of a black hole he wished to investigate.
Orac was instrumental in the destruction of Ultraworld by reflecting its scanning beams. He survived the destruction of the Liberator, being taken off the ship by Vila shortly beforehand, and accompanied the crew to their new base on Xenon. Despite his aloofness, he showed concern for the danger posed to humanity by Muller's android, which was capable of controlling anything computerised, and approved of Del Tarrant's decision to destroy it.
Orac was aboard Scorpio on the ship's final trip to Gauda Prime, teleporting off the crashing ship with Avon. He assisted Avon, Vila, Dayna and Soolin in infiltrating Blake's base. He was not present during the crew's massacre by Federation troopers, making his fate unknown.
