The 36 episode anime series "Special Armored Battalion Dorvack" , seems to have obtained a cult status here in the U.S.. Originally and only broadcast in Japan and Hong Kong from October 1983 to July 1984, it told the story about an alien invasion in the far future of 1999, by a resource starved race known as the Idelians, who resolve to conquer the closest hospitable planet in effort to save their dying population that has been adrift on a colony ship for several years. Unfortunately that hospitable planet is none other than… Earth!
To repel the seemingly unstoppable Idelian onslaught, the Earth Defense Force unleashes their Special Armored Battalion Dorvack. Dorvack units were equipped with humanoid styled mechanical weapon systems or "Mecha" that could convert (or transform) into all terrain vehicles.
The show was a showcase for the Takatoku toy line and the models were licensed to Gunze Sangyo.
