Action Comics #671

In Action Comics #671, Superman and a mysterious figure known only as Mr. Z wake up on the isolated "War That Time Forgot," both suffering from amnesia and stranded in a forgotten battlefield. As a new Lex Luthor emerges in Metropolis, claiming to help end the city-wide blackout, the true nature of the crisis begins to unravel—though the connection between the two events remains shrouded in mystery. Written by Roger Stern and illustrated by Kieron Dwyer, with inks by Brad Vancata and colors by Glenn Whitmore, the issue’s cover by Dan Jurgens and Bob McLeod captures the tension of a world on the edge.
