DC Universe Special: Superman #1

In "Gladiator," Superman faces off against the brutal Mongul on the war-torn planet Warworld, where his strength and resolve are pushed to the limit. With the mysterious Cleric manipulating events and the Eradicator's power at play, Clark Kent's true identity is called into question when Jimmy Olsen encounters a man who isn't who he seems. Written by Roger Stern and illustrated by Kerry Gammill, with inks by Dennis Janke, colors by Glenn Whitmore, and letters by John Costanza, the issue's striking cover by Ryan Sook captures the clash of cosmic power and deception.
