|The Colonial Resistance from an alternate reality save Galactica from certain destruction (Classic Battlestar Galactica Vol. 2 #5).|
Facing an overwhelming force of Cylons, whose approach has been hidden by the very nebula the Colonials use to hide within, Commander Adama orders Galactica to bear the brunt of the onslaught while the civilian ships escape further into the safety of the nebula.
Galactica develops major damage, forcing Adama to authorize Zee's deployment of the temporal warper weapons outfitted on two modified Vipers. Warriors Apollo and Starbuck are pulled from the flight line and assigned to test pilot the craft, with Zee giving them specific instructions that they each only have 10 shots before they need to recharge via a temporal battery.
Understanding this, Apollo and Starbuck launch and test the weapon on two Raiders, finding the results to be effective. Before they are able to deploy it on the attacking basestar, Cylon suicide attacks cause the temporal battery to overload and creates a temporal storm that only Apollo and Starbuck are able to weather (Classic Battlestar Galactica Vol. 2 #1). In effect, this event spawns an alternate reality where Galactica was never built (Classic Battlestar Galactica Vol. 2 #2 & #3).
Following the Battle of Cache, Apollo and Starbuck riding tandem in the remaining Temporal Viper are swept away into a temporal storm, along with the forces of the Colonial Resistance of an alternate reality.
With two capitol ships, Baltifer's former basestar under an alternate Adama's command and an incongruous copy of Galactica herself under the command of an alternate Starbuck, and surviving Vipers from Cache's base, they are deposited in the primary reality.
Vulnerable due to the overload of Zee's temporal battery, Galactica requires an hour to restore the ship's systems while Adama reconciles the loss of Apollo and Starbuck's temporal weapon Vipers. Facing certain destruction, Galactica finds itself saved by the forces of the alternate reality, dispatching the Cylon attackers. This permits the timelines diverge, the alternate reality vessels returning from whence they came, and the reunion of Apollo and Starbuck with the rag-tag Fleet (Classic Battlestar Galactica Vol. 2 #5).
