History Retcon / SpiderMan

** The stories "ComicBook/OneMoreDay" and "ComicBook/BrandNewDay" infamously altered twenty years worth of continuity by erasing Peter Parker and Mary Jane Watson's marriage from continuity. This happened because Spider-Man saved his aunt's life by making a deal with Mephisto, a "demon" character typically used as the Franchise/MarvelUniverse stand-in for the Devil. Peter unmasking in public during ''ComicBook/CivilWar'' didn't happen as depicted; instead, the event was erased from people's memories or they could not remember who was behind the mask.

* ''ComicBook/TroubleMarvelComics'' attempted to redo the origin of Spider-Man by centering around a contemporary group of friends, Ben, May, Mary and Richard, with May having an affair with Richard, implying Peter was born to Aunt May. Fan reactions were so negative that [[CanonDiscontinuity it underwent its own retcon to taking place in a different universe DURING its publication run]].
* ''Sins Past'' and ''Sins Remembered'' establishes that Norman Osborn and Gwen Stacy had a son and daughter, Gabriel Stacy and Sarah Stacy.

* ''ComicBook/TheAmazingSpiderManNickSpencer''

** ''ComicBook/SinisterWar': A lot of Goblin-related shenanigans are adjusted and fixed up within ''Amazing'' #73:
*** [[spoiler:''[[ComicBook/TheAmazingSpiderManJMichaelStraczynski SinsPast]]'' is mostly undone, revealing that Gabriel and Sarah Stacy are actually imperfect clones made to believe that Norman and Gwen were their parents, thus those two never did the nasty.]]

* ''ComicBook/TheAmazingSpiderManRenewYourVows'': As explained in the LettersToTheEditor section, Gerry Conway's ''ComicBook/MarvelNOW2016'' series is set in the same continuity as Dan Slott's ''ComicBook/SecretWars2015'' series, with the differences between them being the result of retcons Conway implemented.

** Finally, the very conclusion of Spencer's run reveals several things [[spoiler:Kindred was in fact never truly Harry Osborn, and had always been every version of the Stacy Twins that had succumbed to clone degeneration and died, twisted and transformed by Mephisto in hell to each become a demonic reverent. The Harry 'Lyman' Osborn of the Brand New Day era is revealed as just another clone...and he knew all along. Finally, the true motivation for Mephisto's involvement in the infamous One More Day is revealed, as the devil forsees a future in which either Peter or his daughter Spider-Girl will ultimately defeat him, thus prompting his intervention in Peter's life to ensure that does not come to pass.]]

* ''ComicBook/OneMomentInTime'' reveals Mary Jane agreed with making the deal with Mephisto in ''ComicBook/OneMoreDay''. The events of ''The Wedding!'' are rewritten so that a red bird, implied to be Mephisto, causes a fat man to fall on Peter and ruin the wedding, altering events up to the present day.
* ComicBook/BlackCat was originally just a laidback adventuress, then Creator/KevinSmith decided to retcon that she was a victim of rape and that her early adventures was a misplaced reaction to it. She was also arrested before and had her identity made public--yet her current FaceHeelTurn is based on [[ComicBook/SuperiorSpiderMan Otto Octavius]] capturing her and her arrest making her identity public.

* ''ComicBook/{{Hunted}}'':
** For years, fans had believed Kraven's temporary death at the hands of [[ComicBook/ScarletSpider Kaine Parker]] counted as removing the former's immortality. Issue #17 reveals that it had not.
** Issue #19.HU retcons the events of [[spoiler:''Shed'' with Dr. Connors claiming that he lost control and murdered his family]] when the comic claimed that Dr. Connors had gone postal for real and was conscious about what he did, only losing consciousness at the end.

* Then, there's the Hobgoblin. The writer at the time he was first introduced,Creator/RogerStern, set up this massive story about a replacement Goblin who was starting to meddle in the affairs of the Kingpin, among others. However, before Stern could reveal the identity, he left the title and the next writer said it was Ned Leeds, a go-to guy for wanna-be Goblins. Between the late 80s and the mid 90s, the role of the Hobgoblin fell to mercenary Jason Macendale, who was ''incredibly'' incompetent. Then, Stern returned for a three-issue mini-series devoted to finally clearing up the mystery of the Hobgoblin.

She automatically hates both because of what happened to her father. In issue 4, however, when Peter finally confronts Gwen (or better, ''another'' clone with her last memoirs), she does say that she forgives him and, in a tie-in, she admits that she's still in love with Peter, but she feels betrayed by him being Spider-Man, though she understands why he does what he does.]]
