Fan Casting Justice League War

A series of abductions have occurred in Gotham City; Batman is implicated due to video footage. Green Lantern stops a kidnapping before attacking the kidnapper, a Parademon, and is almost defeated when Batman appears. The Parademon attacks them both; Batman and Green Lantern chase it into the sewers, where it charges a Mother Box and explodes. They examine the box, deduce it is of extraterrestrial origin, and decide to ask Superman for an answer. Another Mother Box, supplied by Flash is being studied at S.T.A.R. Labs by Silas Stone, father of Victor Stone.
