Earth-52 is a reference to the Forever Evil storyline taking place during the New 52 era.

That origin could work, but i went with versions of them that were our heroes, but chose the villainous path. (Except for Supergirl) Also Godspeed is a better name and character than Johnny Quick. I also felt that Savitar forshadowed his connection to Godspeed by saying "I am the god of speed"

Black Siren being there would be cool except that in this story, E-1 is the first earth these characters have been to. They don't have accomplices. Also again, i wanted dark versions of our heroes. So no Robert.

Same with the Robert situation. Wanted Kara's evil dobbleganger. Also Ultra Girl is a real character from the comic. Ultra Woman however is Wonder Woman's dobbleganger. Also it would be way too crowded with a White Martian.

I was thinking about Tokamak, but then i thought about the whole Deathstorm story involving a dead soul inside of an alive body and i was hooked on my new idea. Also Felicity is my Atomica because i got to reference the comic in some way and in it, there was an evil, female Atom named Atomica.
