The deployment by Apollo and Starbuck in modified Vipers outfitted with Zee's temporal weapons, as well as the destabilization of the temporal battery that powers aforesaid technology, leads to the creation of an alternate reality.
The removal of a key lynchpin from one reality generates a divergent one where the Colonials never create the last of the Colonial battlestars, Galactica.
As Galactica does not naturally exist (aside of the unexplained anomaly of its later presence and capture by Starbuck at some point in his lifetime), Adama is passed over for command and pursues work in the diplomatic service, dissuading his children from careers in the military (Classic Battlestar Galactica Vol. 2 #3).
The Battle of Cimtar still occurs much in the way its counterpart had, resulting in the decimation of Twelve Colonies of Man, and an exodus of the human race under Adama's leadership. Another major divergence is that Adama never pursued Earth and instead fostered a resistance in order to fight the Cylon Empire and regain their homeworlds, despite overwhelming odds (Classic Battlestar Galactica Vol. 2 #2).
Baltar is given command of a basestar, and through experimentation by a rapidly aging Zee, merges with Lucifer. This amalgamates into the cybernetic entity Baltifer (Classic Battlestar Galactica Vol. 2 #3).
Other minor divergences include:
- The naming of Q-Cache 2702 as Q-Cache 7202 in the alternate reality (Classic Battlestar Galactica Vol. 2 #2).
- The use of the word flark in lieu of frack (Classic Battlestar Galactica Vol. 2 #3).
- Red-Eye and Lacerta make a bargain (quickly reneged) to spare Lacerta and his collaborator's lives on Equellus (Classic Battlestar Galactica Vol. 2 #4).
- A divergence in Colonial Warrior uniforms, as noted by Boomer following Apollo's capture (Classic Battlestar Galactica Vol. 2 #2).
- The presence of the battlestar Pegasus during the Battle of Cimtar (Classic Battlestar Galactica Vol. 2 #4).
