History ArmedWithCanon / TheDCU

* ''ComicBook/TheFlashRebirth'' and ''ComicBook/TheFlashInfiniteFrontier'' both take shots at the infamous ''ComicBook/HeroesInCrisis'' event. Said event turned Wally West into a murderer after he had a mental breakdown that resulted in him losing control of the Speed Force. This caused an explosion that killed everyone at the superhero therapy centre Sanctuary, which Wally proceeded to cover up by gaslighting Harley Quinn and Booster Gold and desecrating the bodies of the deceased. Both ''Rebirth'' and ''Infinite Frontier'' (which were released in extremely close proximity to each other) in conjunction basically remove Wally's fault in pretty much everything:
** The ''Rebirth'' run's final arc, "Finish Line", has the reveal that Eobard Thawne possesses a Negative Speed Force power that allows him to hypnotise people and force them to do things, and he uses this at superspeed so nobody knows it happened. He gloats that he's the one who made Wally do all the twisted things he did to cover up the incident.
** The ''Infinite Frontier'' run's first arc, "Blink of an Eye", reveals that the explosion ''itself'' wasn't even Wally's fault. Rather, it was the fault of the Speed Force trying to expel someone tampering with it from within: Wally's enemy Savitar. The ''ComicBook/DCInfiniteFrontier'' one-shot itself also brought back Roy Harper, while the era's last ''Flash'' arc, "One Minute War", undoes ''all'' the other deaths by saying Gold Beetle replaced them with clones at the time of their deaths, something that fans suggested could've been done when ''Heroes in Crisis'' was first published, since it was used as a solution for Wally's "death" in the same story.

* John Byrne's revival of ''ComicBook/DoomPatrol'' fused this with outright CanonDiscontinuity and CosmicRetcon by rebooting the canon to focus on a revamped version of the original roster (The Chief, Robotman, Negative Man and Elasti-Girl), adding new characters Nudge, Grunt and Vortex as additional recruits and ''ignoring the history of all the comic's previous versions'', in particular Creator/GrantMorrison's [[CultClassic beloved tenure]], which had ''itself'' been mildly fired upon during Rachel Pollack's run for Vertigo. This was rectified by Geoff Johns and Keith Giffen making ''everything'' from past writers canonical... Which, considering [[MindScrew the nature of the book even before Morrison's entrance]], fit just fine.

** Valentina herself turned up towards the end of the series ''ComicBook/{{Checkmate}}'', as the new White Queen and without her powers. However, a throwaway spread in ''ComicBook/FinalCrisis'' #4 depicted a dead Negative Woman. In ''Resist'', the civilian Vostok is then shown again, under Darkseid's control. Keith Giffen decided to count the appearance of the dead Negative Woman as canonical, ignoring Vostok's later appearance, and used her in the "Blackest Night" tie-in to ''Doom Patrol''.

** During John Arcudi's run on the series, transgender heroine Coagula was killed by teenager Dorothy Spinner (who was then killed by Cliff), solely because they were two of the last remaining members of the nineties team and Arcudi wanted an excuse for the nineties team to disband so that his own team of unrelated characters could take over. They remained conspicuously dead for nearly two decades, even as other dead DP members like Elasti-Girl and Negative Man were given resurrections. Genderfluid writer Jude Deluca hated this story, and hated that the two characters remained dead even after several line-wide continuity reboots, and so when they got a chance to co-write a story for DC's 2022 Pride anthology, they had Kate and Dorothy show up in a crowd scene, making it canon that they exist in the modern Prime Earth. However, the 2023 miniseries ''ComicBook/UnstoppableDoomPatrol'' by Dennis Culver disregards this and still establishes Dorothy Spinner and Kate Godwin to be deceased.

** The ''Infinite Frontier'' run's first arc, "Blink of an Eye", reveals that the explosion ''itself'' wasn't even Wally's fault. Rather, it was the fault of the Speed Force trying to expel someone tampering with it from within: Wally's enemy Savitar. The ''ComicBook/DCInfiniteFrontier'' one-shot itself also brought back Roy Harper, while the era's last ''Flash'' arc, "One Minute War", undoes ''all'' the other deaths by saying Gold Beetle replaced them with clones at the time of their deaths, something that fans suggested could've been done when ''Heroes in Crisis'' was first published.

* ''ComicBook/AnimalMan'': Tom Veitch infamously despised Creator/GrantMorrison's run that started the 1988 series and gave a new origin for Buddy Baker's powers that involved a shaman mystically granting them in disregard towards Buddy's previously established origin of gaining his abilities by being revived and reconstituted by the Yellow Aliens after he was disintegrated by energy from their spaceship. Quite tellingly, Veitch's arc began wit the shaman smashing clay sculptures bearing the likenesses of the Yellow Aliens as well as Grant Morrison's AuthorAvatar whom Buddy interacted with at the end of their run. Tom Veitch's changes were since mostly ignored by subsequent writers.

** Jamie Delano's run concluded with Buddy Baker permanently transformed into a chimera-like creature and allowing himself to die so he'd be a martyr towards the eco-friendly religion he started after falling out with his wife and cheating on her with another woman. This was done away with in Jerry Prosser's run, which started with Buddy restored to being a human and establishing that the events of Delano's run were [[AllJustADream just a dream]].

* In an issue of ''[[ComicBook/BatmanAndTheOutsiders The Outsiders]]'', Creator/JuddWinick had Arsenal ''completely out of nowhere'' make out with ComicBook/{{Huntress}} and then tell ComicBook/{{Nightwing}} that he'd had sex with her. Creator/GailSimone responded by writing a scene in ''ComicBook/BirdsOfPrey'' where Huntress admitted to sleeping with Arsenal, but then followed up by saying he wasn't very good in bed.
