A time-lost Kryptonian ship, its crew murdered. A missing escape pod. A mysterious attack by a powerful assassin on an insignificant reporter named Clark Kent. These are the clues in a mystery that will take all of Batman’s detective skills and Superman’s incredible strength to solve.   A war from Krypton’s long-ago history has come to Earth, with a warrior determined to wipe out every remaining Kryptonian. The battle is to the death, and if the adopted world of the Last Son of Krypton should die in the process, so much the better.   Now Superman must finish a war that his ancestors began, but he has an advantage that ancient Krypton and its enemies could never have imagined. And its name is Batman.   Experience this epic battle along with other classic stories in SUPERMAN/BATMAN VOL. 6. This volume features comics by superstar creators including Joe Casey (ADVENTURES OF SUPERMAN), Paul Levitz (BATMAN) and Scott Kolins (THE FLASH). Collects SUPERMAN/BATMAN #64-75 and SUPERMAN/BATMAN ANNUAL #4.
