Scramble City is the name of a Transformers OVA (Original Video Animation) created and released in Japan in April 1986. It was created as a promotional video for the new line of 'Scramble City' toys released only in Japan. 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 Transformers: The Movie (considering Ultra Magnus is the only one from the film that appears in it.) or to fill in the 20 years between seasons two and three of the show. It actually takes place years before TF: TM during the early stages of construction on Autobot City.
