The spawn are created through physical contact after Achira possesses a willing host. Several spawn aggregate on a victim's body as strange boils and induce flu-like symptoms. After about a day's time, Achira summons the Spawn and they proceed to destroy a civilization. This process was repeated several times in the ancient world. Spawn were created in 1997 in New York City but were seemingly dissipated as Achira was trapped by the Extreme Ghostbusters on the Brooklyn Bridge.
