The problem with trying to make New Gods some sort of nigh-omnipotent Platonic Forms is that no matter how much the writer tells us through dialogue and narration that this is what they are, every single thing they do in the story will undermine that. It just makes no logical sense.
Platonic Forms, by definition, are immaterial, not locatable in space-time, and causally ineffacious. You can't both tell me that "Darkseid is literally the Platonic Form of tyranny" and tell me that "Superman punched Darkseid," because you can't punch the Platonic Form of tyranny. You can't tell me that Darkseid is a Platonic Form, and that he shoots beams from his eyes, has a son named Orion, has grey skin, knows how to read, whatever, because none of those things can be properties of Platonic Forms. It makes as much sense as saying "redness is ten feet tall," or "in 1954, circularity went on vacation in Malta." So, what you get when you try to present New Gods in this way is the author hyping up how cosmic or whatever they are… only to write them like any other character.
>But OP, that's just because the comics are showing us an avatar/projection of Darkseid so that he can interact in the universe and be fathomable to the characters and audience!
This maybe makes sense if you're just saying "Darkseid is a multidimensional being beyond our intuition," but still makes no sense if you're trying to say he's a litereral Platonic Form, because Forms don't do that shit, either.
>But, even though Forms are non-spatial and immaterial, they can be exemplified by materials and in spacetime
Okay. But if the Darkseid we see is just an exemplification of the Form of Tyranny, that is no more mysterious or special than Stalin's tyranny being an exemplification of the Form of Tyranny, or your basketball being an exemplification of the form of sphericity.
