Over 70% of our planet is covered in water. It nurtures us, sustains us and keeps our fragile ecosystem in balance. Without water, there is no life—plain and simple. And when the very water we depend on gets poisoned and turned into a weapon against us…well, we wind up with something much like the nightmare of “Drowned Earth.”

The Justice League/Aquaman crossover event formally kicked off last week with JUSTICE LEAGUE/AQUAMAN: DROWNED EARTH #1, and it continues this Wednesday in JUSTICE LEAGUE #11. If you’ve been reading, you know that the strange and powerful Ocean Gods have attacked Earth, causing our oceans to quickly rise, and even worse, poisoning their water with a substance that turns anyone who comes in contact with it into an aquatic monster. Already it’s transformed many of the world’s greatest heroes—along with nearly all of Atlantis—and it shows no sign of slowing. But how do you stop the most abundant substance on Earth?

The first chapter ended with a dramatic rescue by Wonder Woman, but in our exclusive preview of chapter two, it’s Mera who gets her moment to shine as she takes on a transformed Swamp Thing…much to the gratitude of a beleaguered Superman and Flash. Enjoy!

JUSTICE LEAGUE #11 by Scott Snyder and Francis Manapul is in stores this Wednesday.
