Plot
DARK NIGHTS: METAL left the DCU transformed in ways both terrifying and wondrous—and only the Justice League is strong enough to face the threats to come…or are they? Four giant beings comprised of the universe’s major energies—Mystery, Wonder, Wisdom and Entropy—who sustain their life force by devouring planets are on their way to destroy the planet of Colu. The only way to take down this unimaginable threat is for the superhero teams of Earth to forget everything they thought they knew and form new alliances.
