On Cybertron, Optimus blissfully performs some data management tasks, until Hot Rod interrupts with news of the battle on Earth. Hot Rod dismisses Cobra's potential to be a threat to Cybertron's new-found era of peace, but Optimus advises Hot Rod to not underestimate them. On Earth, the Autobots begin to track the missing Bumblebee, and Grimlock follows his faint life-signals into the tunnel Cobra excavated. Above, Serpent O.R. overrides the G.I. Joe computers, using them to transport him to Cybertron.
