Nobody knows the exact origin of these beasts from the Dark Multiverse, but what is known is that they do the bidding of The Batman Who Laughs wherever they appear. During the invasion of Earth-0, the Bat-God known as Barbatos summons these great dragons to help his Dark Knights destroy the world, but theyre ultimately defeated by Batman and his allies. These ghastly beasts are as deadly as they are horrifying, and a powerful addition to the army of darkness that threatens to engulf the entire DC Multiverse.
