The constant battle for survival that occurs within every body of every creature. In the epic struggle for life, the BioWarriors defend their home world—the BioCosmos—against the invasive forces of viruses, bacteria, and other infectious agents. Life sometimes has a cruel twist, and the Biowars may also spark a battle of host versus host when one of the BioCosmos’ own cells turns against it. Agent cells can go rogue via contraction of a viral infection or through a genetic mutation. In the story of Biowars, the cells of the Immune System and Nervous System are given human forms, but retain their real world biological powers. All other cells retain their actual forms and biological functions.
