In Japan, the first two seasons of the show were collectively released as a single season entitled , then rebranded as for season 3 (season 2 there), with all seasons aired on
Nippon TV. Following the conclusion of the third season, Japan opted not to import the fourth season, but instead created a series of new animated shows to continue the story, beginning with
Transformers: The Headmasters in 1987, and continuing into
Transformers: Super-God Masterforce in 1988,
Transformers: Victory in 1989, and the single-episode
direct-to-video OVA Transformers: Zone in 1990.
Scramble City Scramble City was a special
direct-to-video episode produced for the
Japanese market, released in April 1986. It served to further promote the new "combiner" figures who had been introduced at the end of season 2, and a few other figures from the 1986 product line (like
Ultra Magnus, Metroplex and Trypticon) who had not yet appeared in the American cartoon, which were all being released in Japan with the sub-branding of "Scramble City." Set soon after the end of the second season, the episode focuses on the Autobots' efforts to construct a new mobile fortress, the titular "Scramble City." When the Decepticons learn of this, their combiner robots are deployed to attack, and a battle between them and their Autobot counterparts ensues, focusing on their "Scramble Power" – the interchangeability of the individual limbs – to the extent that at one point, Breakdown of the Stunticons connects to Superion to damage him. At the episode's conclusion, Scramble City is activated and assumes its robot mode of
Metroplex to rout the Decepticons. However, from the ocean depths, the Decepticons' own city, Trypticon, rises. ==Generation 2==
