The Third Cybertron War is a conflict between the Autobots and the Decepticons that occurred some time prior to the earth year 1985, apparently in the distant past. It should not be confused with the Third Cybertronian War. The Decepticon drone Deceptitran uses encryption quite similar to the Decepticon transmissions of this period, and it's possible he dates from this time, though his occupation of the Tlakakans planet seems to be of a much more recent vintage.
