Based in part from a toy line made by Japanese company Bandai, the series focused on an international group of soldiers fighting to free the world from a scientist who controls much of the Earth's surface.

Millions of people are trapped in the dark mists of the Spiral Zone and transformed into "Zoners" with lifeless yellow eyes and strange red patches on their skin.

The other Black Widows ride Sledge Hammers, a one-man minitank that has triangular caterpillar tracks and has whirling mace arms on either side.

They include: three 1:12 scale six-inch figures with full equipment codenamed Bull Solid, Hyper Boxer, and Sentinel Bear, two Bull Solid cloth uniform and armor sets, two Hyper Boxer cloth uniform and armor sets, two equipment backpacks, two bare human figures, and one vehicle called the Monoseed.

Non-toy media included a notebook, a novel, and an LP/story compilation released in 1986 by Warner Bros. Records and Pioneer Corporation called a Hyper Image Album.

The LP disc in particular contains songs composed by Toshiyuki Watanabe and performed by Tomoko Aran, with the accompanying stories written by Kazunori Itō.

The series' story and other machines, such as a mobile base and special transport for the Monoseeds, were also detailed in Bandai's Model Making Journal.

[8] Because of their extensive detail and high-quality construction, the Japanese Spiral Zone figures are well regarded among toy collectors and often fetch high prices.

The complete Japanese dubbed version of Spiral Zone was released on VHS format in Japan by NHK under their "VOOK" line in 1991 thru 1992.

Although best known for producing toys of construction vehicles, Tonka licensed the rights to Spiral Zone from Bandai and created a line of seven-inch figures that were later based on the animated series.

However, an unofficial DVD set containing all 65 episodes and bonus materials was released in November 2006 by SpiralZone.com, with the cooperation of the show's supervising director, Pierre de Celles.

The site's operator said that de Celles volunteered for the project by providing the original master tapes of the series, which were converted to DVD.

[12] According to the show's former supervising director Pierre De Celles, he wanted to get Spiral Zone to go for the fantastic science fiction direction, but the producers and sponsors discouraged him for doing anything too unusual.
