As Brainiac's alien armies emerge from the bottle cities, Batman and Wonder Woman form a plan to contain them and recruit what new heroes and villains they can to go up against them. Meanwhile, Luthor recruits the members of the Secret Society of Super Villains to create his own army to fight Brainiac.
As Wonder Woman's team begin containing the aliens inside a dome of ice, Batman prepares his own weapon; a toxic gas attack to obliterate the armies as they are contained within.
"Since those days I've learned there is a point in one's life when you consciously make a decision to cross that thin, fragile line you once etched in the sand. And once you do, that becomes a moment you can never take back. But now I have to try." — Cyborg Batman
