In the script that was being produced when Galactica 1980 was officially cancelled, the story "The Day They Kidnapped Cleopatra" tells of Xaviar's continuance of his self-appointed mission of improving Earth's technology in the distant past. In this outing, he pretends to be a god to Cleopatra, however in order to dispel those who doubt Xaviar's claim, she poisons his drink, forcing Xaviar to frantically seek out Jamie Hamilton, Troy and Dillon in 1980 to get medical assistance. Unfortunately, he brings along Cleopatra to the future as well, thus jeopardizing Earth's timeline in the process.
Tellingly, the script does not include mention of the Super Scouts, and seems to take place after the episode "Space Croppers".
