Supergirl, Flash, Monitor and Pariah were among the important characters of Crisis in Infinite Lands, original comic book series from DC Comics, by Marv Wolfman and George Perez, from 1985.

"I wish I could say that he has reached the preliminary stage," Guggenheim told the Fake Nerd Podcast. "Good! This is not true. He reached the draft stage. For the most part, he ended up … Well, he never made it out of the whiteboard. "
