In 1994 DC Comics published Zero Hour, a five issue mini-series designed to not only serve as a major summer crossover but also fix some of the continuity problems that had emerged since the end of Crisis on Infinite Earths. Zero Hour was written and pencilled by Dan Jurgens (who later went on to write and draw Firestorm in The New 52), and represented the dawn of an exciting new era for DC. To kick off this new age, DC followed Zero Hour in August & September 1994 with "Zero Month." As the name suggests all of the main DC books published an issue numbered zero, though each had a different approach to the idea. Some books featured a new origin. Some contained tweaks to the existing origin. Some contained brand new versions of old characters. Some were intended to launch new ongoing series. All of them served as a jumping on point for new and old readers alike.
