After having received a distress call from a nearby colony, Sector Vega, the autobots with humans in tow head off to heed their plee for help. With only Optimus piloting the ship and the others in cryo stasis, he evades the attacking decepticons, only for both to crash land on a Ringworld. Having to deal with a mentally scrambled Lugnut at his heels, Optimus tries to adjust as he dodges not only decepticons, but also metal devouring Wyrms.
