In days long past, the civilizations of the world engaged in long, hard-fought wars lasting decades, and in some cases even centuries. These ancient nations and their enmities have faded into the distant past, leaving behind a legacy of crater-pocked battlefields; forgotten ruins; and highly advanced, animal-like war machines known as Zoids.
In the modern era, the world’s population is divided among far-flung, independent city-states separated by vast stretches of uninhabited territory. These cities are united by satellite communication, trade, and the Zoid Battle Commission. Ambitious leaders gather talented Zoid pilots into teams in order to participate in the Commission’s organized and highly-regulated combat engagements, all in the hopes of winning fame and fortune on the battlefield. Zoid battles have become the most popular form of entertainment in the world, and the services and industries required by Zoid teams drive the economies of whole cities. This is the story of Sunset Shimmer, her friends, and their adventures in the industry of professional Zoid combat.
