Synopsis:
Fortress Maximus' Autobots unsuccessfully try to build a new body for Optimus Prime. They then set out to find the Ark. A delegation from his ship meets Grimlock, who is unhappy that Prime might return. Goldbug then turns himself in to appease Grimlock, but the Dinobot still decides to fight Fortress Maximus for leadership of all the Autobots. Goldbug, meanwhile, finds Blaster, and persuades him to fight Grimlock on Fortress Maximus' behalf, on Earth's moon. The combatants prepare, unaware that Ratbat is preparing to assault them as they fight.
