The parademon scout was a minor antagonist in the 2017 film Justice League, which is a part of the DCEU. He was a parademon that Batman lured out.
Creation and Purpose
Like all other Parademons, the Scout was created using dark powers by Steppenwolf and Darkseid to be their soldiers. Scouts were created to capture specimens to transform into Parademons. If captured, scouts were designed to self detonate.
Lured out by Batman
Batman has been tracking the patterns of the Parademons. He captures a burglar and uses him to lure out a Parademon Scout, whom smell fear. The Scout does arrive and tries to grab the Burglar, but Batman pulls him out of the way.
Capture and Demise
After pulling the Burglar out of the way, Batman jumps onto the Scout. The Scout persists to resist until a siren sends the flying Parademon out of control. Batman is able to capture him with a net, but the parademon self detonates.
