OVA • Transformers: Scramble City
Fight! Super Robot Life-Form Transformers: Scramble City Activation (戦え！超ロボット生命体トランスフォーマー スクランブルシティ発動編 Tatakae! Chō Robotto Seimei-Tai Toransufōmā: Sukuranburu Shiti Hatsudō-hen), sometimes referred to as just Scramble City (スクランブルシティ Sukuranburu Shiti) is an episode of The Transformers released as an OVA (Original Video Animation) in Japan in April 1986. It was created as a promotional video for the new line of 'Scramble City' toys and the cassettes were paired with the toy sets. Despite strong belief (such as that voiced on the 20th Anniversary DVD bonus commentary for the episode), it was not meant to introduce Japanese audiences to the new characters from The Transformers: The Movie (considering Ultra Magnus, Ramhorn, Steeljaw, and Ratbat are the only ones from the film that appear in it). Chronologically, it takes place years before the movie during the early stages of construction on Autobot City.
Beginning with a recap of the coming of the Transformers to Earth and the story of Devastator, the OVA then gets its original story underway, as the Autobots are shown to be in the midst of constructing the powerful "Scramble City", overseen by their newest arrival, Ultra Magnus. 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 OVA'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.
This cliffhanger was never resolved as no direct sequel was ever produced. An extended commercial, called Scramble City Toys but often mistakenly identified as Scramble City 2, was released, but rather than wrap up the cliffhanger, it retold the OVA through stop-motion animation of the toys themselves, with one addition - the introduction of Galvatron, erroneously presented as one of Megatron's troops, rather than the recreated Decepticon leader himself.
