Nobody talks about this one. A 1985 studio parody that takes a space colonist mecha show and drops it wholesale into 1920s Chicago, complete with tommy guns, prohibition raids, and whatever the animators thought would be funny that week. It's the kind of thing that only exists on a VHS bonus tape, which is exactly why it survived: too weird to market, too specific to forget. The gap between "serious military sci-fi" and "gangster comedy" should not work. Here it does, because nobody was trying to make it work in the first place. If you've ever wondered what happens when animators are given one episode and told to break their own show, this is the answer.
Ginga Hyouryuu Vifam: Chicago Super Police 13 is a one-episode special from 1985 that parodies Ginga Hyouryuu Vifam by moving it to Chicago in the 1920s. Its genres are action and comedy, so the new setting serves as a backdrop for jokes. The short first came out as a bonus on the VHS release of Ginga Hyouryuu Vifam: Keito no Kioku - Namida no Dakkai Sakusen.
