A four issue limited series that teamed-up the Transformers with the other popular Hasbro property of the 1980s, G.I. Joe. The Joes and the Autobots must join forces to stop the Decepticons and Cobra from destroying the world. The story suffered from the need to maintain extremely tight continuity among Marvel Comics titles at the time, that is events that happened in the ongoing monthly titles must reflect in the limited series too. However, while there were references in the regular monthly issues of the Transformers comic to the story line of this crossover series, there were no such matching references in the monthly issues of G. I. Joe. That comic's lead writer, Larry Hama, did not consider the events of the cross-over series to be "canon", though a later crossover that he DID take part in led to the Generation Two relaunch of the Transformers comic.
