* AuthorsSavingThrow: Following the controversial [[spoiler:death of [[ComicBook/MarvelComics2 MC2]] Peter Parker and the emergence of Mayday's angst-ridden vengeful attitude]] in ''ComicBook/SpiderVerse'', long-time artist Ron Frenz made his feelings known in an interview, pointing out character and continuity inconsistencies. When the time came to collaborate on a short story involving Mayday with Tom Defalco for the Spider-Verse tie-ins, he and Tom left several clues that indicated this might not necessarily be the Mayday fans had enjoyed reading from 1998-2010, but an entirely different alternate version. ''ComicBook/SpiderGeddon'' later revealed that [[spoiler:those characters were actually from this continuity, but they resurrected this version of Spider-Man]].
* OnlyBarelyRenewed: The series floated on the cancellation line throughout its run. It managed to make it to 100 issues before the series was finally cancelled. Due to this happening right on the heels of ''ComicBook/OneMoreDay'', Editor in Chief Joey Quesada gave the green light to relaunch the series as ''Amazing Spider-Girl'' to placate fans who wanted Peter and Mary Jane to remain married. Sales continued to drop with the relaunch however and when it was cancelled at issue 30, it was relaunched ''again'' first as a Digital Series and then as a backup.
* UnCanceled: Many, many times.
* WhatCouldHaveBeen: TheReveal about [[spoiler:Darkdevil]] never happened despite being set up in [[AbortedArc Venom and Gwen Reilly arcs]]. WordOfGod is that [[http://comicboards.com/php/show.php?rpy=spidergirl-2010120514052861 he probably would have told the Parkers the truth had the series continued]].
* WriterRevolt: Oooh, boy - Mayday's creators were ''not'' thrilled at what Dan Slott had done to her during ''ComicBook/SpiderVerse'', going so far as to subtly hint that the Mayday they were seeing was not the real one. Even more so, when they returned with a set of backstories for ''ComicBook/SecretWars2015'', they hint that Mayday just hasn't gotten over her father's death and everyone keeps calling her "Spider-Girl" instead of the "Spider-Woman" name she took up for herself.
