Parademons are the creatures the makeup Darkseid's forces.
Darkseid's Invasion of EarthEdit
In the film, they are not inhabitants of Apokolips, trained to be soldiers for Darkseid like in the comics, but aliens from conquered worlds, transformed by nanomachines into an army of killers. Desaad even tries to transform Superman into a "Super-Parademon" by using these nanomachines, but the process is interrupted by Batman
The first Parademon being tracked by Green Lantern and Batman tries to blow itself up with them. Batman takes out a few Parademons with a bomb like in one in Darkseid's base. The Parademons have dark green, electrically charged blood that doesn't stick to clothing or skin. The superheroes wantonly kill Parademons even after learning they're living beings kidnapped from planets and genetically modified—and some of them are human. Victor's transformation into Cyborg partially involves undergoing the same process, but he keeps his sense of self. The transformation that would turn them into Parademons that starts with the eyes.
The means in which Parademons are created involves subjected captured bystanders to this, to a horrifying extent. Victor's transformation into Cyborg partially involves undergoing the same process, but he keeps his sense of self. What ultimately stops Darkseid is Cyborg, who has a combination of Apokaliptian technology and another alien tech which allows him to interface with the Mother Box and reprogram it to send Darkseid and his army back where they came from.
Desaad hoped to experiment on the captured Superman and using his Kryptonian DNA to create a new "Super" type of Parademon.
- Parademons first appeared in New Gods #1 created by Jack Kirby.
