Superman: The Man of Tomorrow #13

A massive superhero clash erupts across this 1999 cover, with Batman charging in the foreground while Superman, Wonder Woman, Supergirl, The Flash, Green Lantern, Steel, and a host of other Justice League and Team Superman figures surge into battle behind him — all under the ominous banner of "Reign of the Robots!" Paul Ryan's pencils and Dennis Janke's inks pack the image with kinetic energy, weaving together an impressive assembly of DC's finest in what promises to be an all-hands-on-deck crisis. With Louise Simonson writing and the story titled "Madness!", this issue delivers exactly the kind of sprawling, high-stakes adventure that made the Superman titles of this era so compelling.
