Commander Xaviar was a human refugee from the Twelve Colonies of Man, who escaped in a rag-tag fleet of refugee ships for Earth. Following thirty years of travel, the fleet arrived to find Earth too technologically inferior to be of help against the Cylons, and so disunited their reveal would pose a threat to its political stability. Xaviar, disgusted by the timid proposal of non-interference by Commander Adama, used a time-machine to travel to the 1940s, where he began aiding Nazi Germany in the development of advanced rocketry, believing that by helping the Nazis win the war he could initiate a massive technological renaissance that would make it on par with the colonies soon enough. His attempts were foiled by Cpt. Troy and Lieutenant Dillon of Galactica.
