So do you think the Dark Multiverse has changed what we know in regards to the New Gods being singular? I mean there have been to my knowledge Four versions of Darkseid in the Dark Multiverse the first looked like Superman and he battled in Barbatos's army. The second had merged with Necro durring a Blackest Night alternate world, the Third was Batman named Dark Father who killed his Darkseid and took his power and the latest one is in that Crisis World where Darkseid won Final Crisis.
I personally think this is an interesting concept and proposes a good question of what or whose fears and regrets these Darkseids represent in the Dark Multiverse. I doubt they are avatars because if I'm not mistaken Darkseid is against Perpetua and by extension the Darkest Knight so I do think these are alternate versions. I have to admit as much as I like the character of the Darkest Knight I feel stuff like this is what should have been explored. Though I remember an idea Rob of the Comics Explained YouTube Channel mentioned he talked about how he'd love a Lightseid to be introduced and I think that'd be funny to see as well even if it was a comedic character I'd love it especially to see a version of Darkseid that's good to the point of it being weird lol.
