Written by G. Willow Wilson and illustrated by Cian Tormey, Lazarus Planet: Revenge of the God pits the Gods of the DC Universe against Wonder Woman and the Shazam family.
"But for how long can they fight against the ones that gave them their powers in the first place?" reads DC's description.
The storyline takes place immediately after the core Lazarus Planet event. Due to whatever occurs, the DC gods of the Multiverse decide to take down the superheroes (some of whom like Shazam are their champions) and "the world they've sworn to protect," which presumably means Earth-Prime.
In a vibe that may remind some of Zeus's speech to Hercules during the mid-credits scene in Thor: God Thunder, it seems like the gods of the DCU have sat around for too long and let superheroes take their place as the idols of mankind, and decide it's "their time to remind the selfish mortals of their existence and take back the world with something more powerful than belief...fear."
Only Wonder Woman and Shazam stand in their way.
