History Retcon / Batman

!!ComicBook/{{Batman}}

!!Franchise/{{Batman}}
* In another comic-book retcon, Batman is now known as a superhero who refuses to use a gun or to kill (well, most of the time). This was not true in the first year or so, although he didn't actually kill humans very often and most villains died from KarmicDeath. See PayEvilUntoEvil. Another notable case concerns events in the story arc Hush. The titular villain appears revealed as [[spoiler: long dead Robin Jason Todd]], before he turns out to be an imposter (and not the real Hush, at that). Later, a retcon revises the story so that [[spoiler: it was a resurrected Todd after all, but he escaped to be replaced by the imposter mid-battle]].
** Since while everyone's histories were changed for the ''ComicBook/New52'', Batman's was largely unchanged -- meaning while superheroes only appeared 5 years prior to its events, Batman had to be in action for ''ten'' because he ''still'' had ''four'' Robins in his history!

* ''ComicBook/BirdsOfPrey'': In the {{ComicBook/Blackhawk}} comic series, when Zinda Blake was brainwashed by Killer Shark to be his partner Queen Killer Shark, she had no loyalty to him. She abandoned Killer Shark to escape the Blackhawks twice in ''Blackhawks'' #200 and #204. And when Killer Shark and Queen Killer Shark capture the Blackhawks in #225, she betrays him, threatens his henchman to turn on him, and imprisons him with the Blackhawks. In ''Birds of Prey'', her brainwashed personally is shown to be completely loyal to Killer Shark, with her being completely in love and devoted to him, to the point that it's implied that she has been sleeping with him in the past.
* Despite the fact that [[ComicBook/{{Batgirl 2000}} Cassandra Cain's]] entire upbringing was a never ending training from hell, she did love her father, and yet she ran away from him. The reason was that her first kill was the very first time she had witnessed death up close and due to her body reading abilities she thought it to be very, very, scary. Thus she found out her upbringing was evil. Now enter the last issue of Adam Beechen's mini series about her where it is revealed that she hated her dad all along, and that she had actually witnessed her father committing murder up close many times before her first kill.
* [[Characters/{{Robin}} Stephanie Brown]] died at the end of ''[[ComicBook/BatmanWarGames War Games]]'', as after she was tortured by Black Mask, Leslie Thompkins withheld vital medical treatment. Her autopsy photos were shown to prove the dangers of crime-fighting to Misfit. Batman never had a [[ShrineToTheFallen memorial case]] for her because [[WordOfGod "she was never really a Robin"]]. [[http://www.sequentialtart.com/article.php?id=488 This wasn't a very popular decision]]. [[AuthorsSavingThrow Except]] she never died: Leslie faked everything because her secret identity was compromised, her body was switched with an overdose victim with a similar body type, and Batman knew this all along making his relationship with [[ComicBook/RobinSeries Tim]] even more strained since he neglected to clue him in. Here's Webcomic/{{Shortpacked}} [[http://www.shortpacked.com/blog/comic/book-7/01-dr-jan-itor/spoilerlives/ on the last one]].
* [[ComicBook/{{New52}} The New 52]]:
** Just a year in and they're already contradicting themselves. ''ComicBook/TeenTitans'' had Tim Drake mention his time as Robin and that there had been prior versions of the Titans. When the trade paperback came out, [[OrwellianRetcon this was revised with Tim always]] being ''Red'' Robin (never regular Robin, though still Batman's sidekick), and omitting mentions of prior Titans.
** The Titans were also originally referenced in the ''ComicBook/{{Batwoman}}'' series, with Flamebird claiming to have been part of the team and having fought Comicbook/{{Deathstroke}}. This dialogue also found itself edited when it came time for the trade paperback to be released.
** The thing with Tim never having been a Robin was left ''in'' when it came to the trades collecting ''Batman'', with the Bat-Computer specifically mentioning it. Oops.
* Dick Grayson and Barbara Gordon's relationship was retconned in the 1990s. Pre-Crisis, Barbara was almost a decade older than Dick and the two had a purely platonic relationship. Since the '90s, however, Barbara (now [[AgeLift aged down]] to be either the same age as Dick, if not slightly younger) is treated as one of Dick's first loves dating back to his days as Robin.

* In ''ComicBook/BatmanHush'', it was stated that Clayface was impersonating Jason Todd when "Jason" fought Bruce. In ''Under the Hood'', when Jason became the ComicBook/RedHood, it was retconned that it was indeed the real Jason who started the fight, but he swapped out for Clayface before the end.

** The canary scream is either due to radiation, a wizard's curse, a metagene, or human experimentation involving aliens.
* ComicBook/{{Captain Carrot|AndHisAmazingZooCrew}} has always operated under cartoon physics, but they were the burlesqued physics of GoldenAge comics, not the outright ToonPhysics of ''WesternAnimation/LooneyTunes'' as shown in ''ComicBook/TheMultiversity''. No previous incarnation of the character, even relatively recent ones, could possibly have survived [[spoiler:decapitation]].
* During ''The Judas Contract'' arc of ''The New ComicBook/TeenTitans'' it was stated that Terra was doing everything by her own free will. In the 2000s, it was shown that Deathstroke had actually drugged her into behaving that way.
