Both Autobots and Decepticons are stuck in a never-ending parade loop. Hot Rod, who was not caught in the loop, and Clobber, who was rescued from it by the former, attempt to hack into it to free their fellow Cybertronians. The attempt fails and both are chased by mysterious tentacled troopers with Clobber getting recaptured and needing Hot Rod's help twice. The two later lure in a squad of the tentacled troopers before crushing them under the debris of a derelict building. They later join Perceptor who reveals that the loop the other Cybertronians were currently experiencing is slowly draining them of their sparks. With that in mind, Hot Rod resolves to free everyone from the loop and end the invasion on their home planet.
