Galvatron explored various galaxies in search of parts for his master's body. Eventually he came across a large metal jointed sphere and a piece of massive shoulder armor. He instantly recognized these as parts of Unicron's body. He was about to report them to Unicron when he realized he could sabotage it then and there. He almost fired his antimatter cannon at it and destroyed them when suddenly he started to convulse again.
"You forget our psychic link, Galvatron." said Unicron's voice in his head, "Bring those parts to me, or you will suffer the consequences."
"You're bluffing, Unicron!" said Galvatron, "You wouldn't destroy your only hope for recreating your body!"
"I have other heralds; I can destroy you and still reclaim my body. Remember Cyclonus? Or Scourge?"
"I... will... obey, Unicron." said Galvatron to spare himself the pain of Energon starvation.
Meanwhile, back on Cybertron the Autobots were trying to plan how they would defeat Unicron.
"The Matrix and the Allspark both have the power of Primus." said Crosshairs, "Maybe we can destroy Unicron with them?" Drift shook his head.
"I'm afraid that the portion of His power in those relics is too miniscule to defeat our enemy." said Drift.
"There has to be some way." said Hound.
"No." said Optimus, "There is no way to defeat Unicron without the full power of Primus Himself, who has been asleep for millions of years."
"If Unicron has awakened, then shouldn't Primus be awakening soon?" said Bumblebee.
"Unicron only awoke because Primus has returned to the universe." said Optimus, "His slumber was disturbed by a momentary surge of Primus's energy."
"Why didn't he awaken when Cybertron was destroyed? Wouldn't that be the perfect time to awaken and resume confusing the universe?"
"Unicron cannot sense when Primus's inactive spark is destroyed. Only when it momentarily reactivated could he sense the surge."
"Is there nothing we can do?" said Crosshairs.
"If we can rescue Megatron," said Prime "he might have evaluated some kind of weakness, be it physical or mental."
"Well, let's get to work trying to find him!"
"It will be difficult, but we must do it."
