 Marvel Comics editor @-@ in @-@ chief Joe Quesada felt dissolving the Peter Parker and Mary Jane marriage and returning Spider @-@ Man to his roots was necessary to preserve the longevity of the character for the next 20 or 30 years . Quesada said he and other previous editors @-@ in @-@ chief had long been seeking an opportunity to begin a new methodology in which to tell Spider @-@ Man stories , but had not found a reasonable way to do so . Quesada said , " It 's very easy to un @-@ marry a character , or fix something like that : you just do a huge universal retcon , and say a few events in history didn 't happen . But that 's really not the way we do it here at Marvel . " Quesada found an opportunity to address this in the events of the 2007 Civil War mini @-@ series , which resulted in the unmasking of Spider @-@ Man 's identity to the public . Quesada knew J. Michael Straczynski was planning to end his run as a Marvel writer , so he personally approached Straczynski to propose " One More Day " as his final project .
