Terror of the Atomic Skull
I dunno why I was thinking of this, but I just got a fun little idea into my head. If you don't get the list's name reference then read some more Superman comics lol. Well like the name implies the series is about the Atomic Skull, specifically the Joe Martin version and how I would write a comic featuring him. Despite the title, it's also a nod to the cheesy sci-fi movies of old and if I had to describe the tone of this idea, it would be a comic with a lighter tone made in mind in compared to the DCU presented. I think it would work best as an Alt. Universe or Elseworld story than a main universe one.
This list is incomplete and more will be added later to it.
