Synopsis
Following the events of the limited series crossover Infinite Crisis, every DC comic series jumped ahead in-story by one year. The events of the missing year were depicted in real time in the weekly comic book series 52. The "One Year Later" event started in March 2006, starting the same week that Infinite Crisis #5 went to press, and before the first issue of 52. Most first issues bearing the "One Year Later" logo were the first parts of multi-issue storylines, and featured major changes to the status quo of each character, often intentionally left unexplained as these details would be filled in by the remaining issues of Infinite Crisis and the 52 series.
Numerous prominent heroes were missing or inactive for most of the year as the "One Year Later" issues commenced. Heroes known to have been gone for the missing year were Aquaman, Batman, Blue Beetle, Green Arrow, Hawkman, Martian Manhunter, Nightwing, Robin, Superman, and Wonder Woman. The Flash has been missing, but Jay Garrick had been protecting Keystone City in his absence.
