The destruction of Unicron has resulted in the formation of a colossal black hole that now threatens the safety of Cybertron and the entire universe. Reporting from a remote station, Red Alert informs the Autobots on Cybertron of the black hole's continued expansion and the resultant destruction of the planet Moriturus, forcing Optimus Prime to issue a drastic command: the complete evacuation of Cybertron. The Autobots arrange to relocate to Earth and adopt vehicular forms scanned from the planet by Jetfire to hide in plain sight among humans.
