An additional Chapter in the Crisis on Infinite Earths story. Because of length, 12 issues was the most the story could be told in. Some of the issues ever even over-sized which inflates the true allowance of page count to the story. This one-shot was written by Marv Wolfman, who wrote the original maxi-series. This story can or cannot be taken as canon, it is up to the reader, since Crisis was about removing universes anyway. This issue is intended to be read after issue #4 of Crisis on Infinite Earths for those who want to know its canon placement.
