Xaviar: the renegade Colonial commander
Xaviar was a commander and council member of the refugee fleet that fled the Twelve Colonies of Man for Earth. Disgusted by Commander Adama's policy of non-interference, he used a time machine to travel to the 1940s and aid Nazi Germany, hoping to force Earth into a technological renaissance.
In Galactica 1980, the sequel to the original series, Commander Xaviar was a human refugee from the Twelve Colonies of Man, who escaped the Cylon onslaught aboard a rag-tag fleet of refugee ships bound for Earth. When the fleet at last found Earth, Earth proved too technologically inferior to stand against the Cylons and too politically disunited for the survivors to reveal themselves without endangering its stability. (Galactica 1980, "Galactica Discovers Earth, Part I")
A council member's despair#
Xaviar served as a commander and member of the council that governed the surviving fleet. After years of flight from the Cylons, the fleet reached Earth only to discover a world far behind the Colonies in its technology and fractured by its own divisions. The survivors judged that openly revealing themselves could threaten Earth's fragile political stability, and Commander Adama favored a careful policy of gradually and secretly advancing the planet's scientific development rather than intervening directly. (Galactica 1980, "Galactica Discovers Earth, Part I")
Sabotage of history#
Disgusted by what he saw as a timid proposal of non-interference, Xaviar broke with the fleet's leadership. He used a time machine to travel back to the 1940s, where he began aiding Nazi Germany in the development of advanced rocketry. His aim was to speed up Earth's technological development so that, by 1980, the planet would be able to defend the fleet against the Cylons. (Galactica 1980, "Galactica Discovers Earth, Part I"; Galactica 1980, "Galactica Discovers Earth, Part II")
Defeat#
Captain Troy and Lieutenant Dillon of Galactica, helped by the reporter Jamie Hamilton, followed him back to 1944 and foiled the plan. Xaviar escaped, tried to recruit the physicist Donald Mortinson in 1980, and later came back disguised as the pilot Nash in a scheme to hold Galactica's Super Scouts hostage, which Troy and Dillon also stopped.

Galactica: the last battlestar of the Colonial Service
In the Original Series continuity, the Galactica was a Colonial battlestar that served over five hundred yahrens in the Thousand-Yahren War. After the destruction of the Twelve Colonies of Man at Cimtar, it survived to lead a rag-tag fugitive fleet on the search for Earth.

Cylon
The Cylons were a race of sentient machines created as military robots by Graystone Industries on Caprica. Built from research into artificial consciousness, they rebelled against their human masters, fought a long war, and forty years later returned to annihilate humanity.

Earth
Earth was a world settled by the Thirteenth Tribe roughly four thousand years before the fall of the Twelve Colonies. Once home to a flourishing Cylon civilization, it was reduced to a radioactive ruin by a nuclear holocaust, and the Colonial fleet abandoned it days after at last reaching it.
