In her quest for power and dominance, she rules absolutely and in totality, using her children—the Monitors and Anti-Monitors—as her heralds and destructors. But a group of heroes has banded together across multiple worlds in a lastditch effort to stop her from destroying all of existence: Owlman, President Superman, Iris West, Captain Carrot, Guy Gardner, and others have chosen to make their final stand in a battle they’re destined to lose! *Source: dccomics.com
