Zoids are beast-like fighting machines used in both everyday use such as transportation, and special use such as war. Some types of Zoids, know as Organoids, are miniature Zoids that are living organisms. These Organoids have the capability to fuse with a non-living Zoid and make it much more powerful. Van (Ban) Freiheit discovers a Zoid Organoid in an abandoned laboratory while running from two strangers piloting Zoids. (myanimelist.net)

Long ago, a war was waged between the forces of darkness and light as Dark Brings--stones containing dark power beyond human ability--put the world at risk with their destructive force. In order to stem the tide of darkness, a lone swordsman used holy power known as the Rave to destroy the source of every Dark Brings. The resulting explosion, which came to be known as the Overdrive, destroyed a tenth of the world; fragments of the Rave were scattered throughout. (myanimelist.net)
