Parademons are the personal shock troops of Darkseid of Apokolips. They are genetically created in Apokolips' laboratories and serve as his loyal army. Some Parademons are bred from human stock, culled from the lowly Hunger Dogs that reside in the Armagetto district of Apokolips. When Apokolips decides to mount an inter-planetary invasion (usually Earth), he sends in waves of Parademons as the advance force. The Parademons have engaged in combat with several of Earth's super-heroes, notably the Justice League of America.
