>>116279717>>116280439Dark Multiverse is formed from dreams and nightmares from people in the main universe, which means all events that happen in the main Earth end up having variations there.
We technically have already seen a Dark Multiverse Superboy Prime for example during the Tales of the Dark Multiverse- Infinite Crisis issue.
Same thing would go to Darkseid and Anti-Monitor, they'd have nightmare versions too due to interacting and being remembered by people form the real universes.
At this point though, it hasn't been clear how these nightmare versions of cosmic entities compare to the real deals.
