Parademons are the basic soldiers of Darkseid's armies. Though their strength is in numbers, through their sheer dedication to their lord, they are formidable on their own.
This is their ninth animated appearance. They appeared in The Super Powers Team: Galactic Guardians, the DC Animated Universe (Superman: The Animated Series, Justice League and Justice League Unlimited), Batman: The Brave and the Bold, Superman/Batman: Apocalypse, Justice League: War, Lego DC Comics Super Heroes: Justice League vs. Bizarro League, DC Super Hero Girls and Justice League Action.
The design of the Parademons are reused from the DC Animated Movie Universe series of films.
