The Weapon of Raid Machines, or WORMs, are artificial lifeforms consisting of millions of nanocells. They're the main antagonists of the series. The WORMs are able to take forms of life they see. These machines were responsible for annihilating one third of earth's population. Although most are defeated in the war, some survived and resurfaced. The remaining WORMs are combated by the Sky Girls and their Sonic Divers.
