Post a concept for an Elseworlds story.
For those who do not know, Elseworlds was an imprint of DC Comics dedicated to alternate scenarios featuring well known DC characters. For example Mark Millar's Superman: Red Son begged the question: "What if baby Kal El's rocket landed in The Soviet Union instead of Kansas?"
It can be drenched in detail or a mere sentence long.
Also feel inclined to list creators you would want to tell such a story.
My idea for an Elseworlds type tale would detail an alternate reality where instead of the concept of the superhero essentially becoming prevalent in the 40s with the JSA, as it was with Post Crisis continuity, superheroes always existed since humanity began. What if there were superheroes in Ancient Rome? What if there were superheroes in Medieval Times? How would this affect the modern DC Universe as we know it?
