In more modern times, the being known as Pariah performed an experiment similar to the one Krona attempted long ago on a parallel Earth (this was changed later to an alternate world in the Post-Crisis single universe).[citation needed] This experiment resulted in the reawakening of both the Monitor and the Anti-Monitor and the destruction of Pariah's Earth and his universe.[citation needed] The Anti-Monitor rebuilt his army, taking over Qward and using the Thunderers as his own private army, as well as creating the Shadow Demons from the elite of the Thunderers.[citation needed]
