So here's the short version if you haven't been keeping up: As The New 52 era came to a close and DC Rebirth began, the version of Superman that we'd been following for the past 5 years was apparently killed, leaving a void that would be filled by his predecessor from the previous DC continuity. See, the pre-52 Superman -- you know, the one who come to Earth from Krypton in John Byrne's Man of Steel and fought Doomsday back in 1994 -- managed to survive the destruction of his universe due to the events of Convergence, spending a year in the Bottle City of Metropolis, having a kid with Lois Lane, and then somehow winding up in the current DC Continuity where he lived a quiet life on a farm until he was needed.
If it sounds complicated, that's because it is, but that also makes it one of the most compelling mysteries in superhero comics right now. And there's one additional wrench in the works: Clark Kent, a mild mannered reporter for a great metropolitan newspaper who exists completely separately from Superman. Now, as "Superman Reborn" is set to kick off in this week's Superman #18, we're about to get the answer to one of DC's most compelling questions: Who the heck is Clark Kent?!
