When the Anti-Monitor reawakened, he re-established his rule over Qward, and transformed several of the Thunderers into "Shadow-Demons" that he then used to help him in his plans to destroy all positive-matter universes, so that the anti-matter universe would increase in size, making him even more powerful. These creatures could kill by touch and murdered trillions. Eventually, however, the Anti-Monitor was destroyed by the heroes of Earth, and the Weaponers recovered control of Qward. Pre-"Crisis", the Anti-Monitor absorbed the entire anti-matter universe, killing the inhabitants in the process, although this was seemingly reversed after the battle at the beginning of time.
