Fanon Discontinuity / Avatar: The Last Airbender

• Avatar: The Last Airbender:
  • The episodes "The Great Divide" and "Avatar Day" receive this, although the latter sometimes gets a pass as it fills in history on one of the previous Avatars. The former was actually acknowledged in "The Ember Island Players" where the actors recreating the cast's travels briefly mention walking through the Great Divide before deciding to just fly over it.
  • The entire third season is sometimes treated as non-canon due to its use of filler and some odd pacing, in addition to many plots that Bryke said they would explore (such as Kuzon's backstory, Zuko finding Ursa ^note which did happen in the graphic novel trilogy The Search, though the storyline was fairly divisive in addition to the Fan-Disliked Explanation, and Combustion Man's identity) were never touched upon at all. The ending is also highly controversial within the fandom, with quite a few fans having a problem with energybending and/or Aang allowing Ozai to live.
  • It's implied throughout the show that Ty Lee's friendship with Azula was based mostly, if not wholly, on the fear of what would happen if she disobeyed her. Good luck finding fans who subscribe to that, with many (especially shippers) preferring to have Ty Lee as Azula's Morality Pet, who often tries to redeem and rehabilitate her post-series. Azula's voice actress believes they had a close relationship although she also recognizes it as abusive.
• Some fans consider the post-series Dark Horse comics in general as non-canon, with The Promise, The Search and Smoke and Shadow being the ones that get ignored the most. The Rift, North and South and Imbalance don't get the same backlash as the others, but are still ignored for the most part.
  • The Promise is disliked for Zuko asking Aang to kill him if he ends up like his father in part 1, followed by his breakup with Mai in part 2, to the point that he suffers from a Designated Hero syndrome with those feeling that he becomes unlikeable as a result of this and the two below mentioned trilogies, not unlike Mai in Smoke and Shadow (see below).
  • The Search comics get the most hate for the Fan-Disliked Explanation of how Ursa disappeared. Ursa married another man after running off and had a daughter with him after wiping her memories of her previous life, many feeling it clashed with the Mama Bear portrayal Fanon held her to. Also several Toph fans were very angry with the character's absence in the latter (though she does make a brief appearance in part 1).
  • Smoke and Shadow has also fallen into this among Azula fans who want her to redeem herself. Near the end of part 3 it has Azula running away in defeat again. There is also the fact that Mai suffers from massive Designated Hero syndrome in that we are supposed to agree and sympathize with her but she ends up becoming a completely unlikable character especially with how much she mistreats Zuko.
  • Zuko and Azula's half-sister Kiyi has a tendency to be quietly ignored by fans and you'll be hard-pressed to find fanfics that mention her. She's generally seen as a cute but unneeded character. Being heavily tied to the controversial The Search comic doesn't help.
• The Sequel Series, The Legend of Korra, has a mixed reception.
  • Some see it as a faithful follow-up to the original series, while others do not.
  • Some supportive fans do not see it as faithful to the original but appreciate the story independently of its predecessor.
  • Those who don't take issue with either certain elements (the Dieselpunk/Gangster Land setting rather than Medieval Stasis being most prevalent), the somewhat rapid establishment and changing of the Love Triangle between first Mako/Korra/Bolin then Korra/Mako/Asami, and they feel that the characters are less compelling overall. There are some groups that deny the entire series exists, because they think it contradicts the established canon of ATLA, their ships from the original series were officially sunk, or they think it is written poorly when compared to the original series.
  • Other fans dislike Aang's supposed neglect of Kya and Bumi to teach Tenzin more about the Air Nomads, feeling that it clashed with his established personality too much.
  • Some fans dislike the apparent neglect of the Gaang as Korra's teachers (despite spending over a decade with the White Lotus with a foundation of high aptitude as a toddler) and world leaders. What some perceive as arbitrarily creating the drama of Korra's story.
  • The Reveal of the Avatar's origin and how they're part of a standard Western-style Good vs. Evil conflict is greatly disliked by fans for destroying the mystery of Avatar and clashing heavily with the Eastern-style worldbuilding that makes up the bulk of the franchise.
  • There are fans who dislike the apparent erasure of the original Avatar Cycle in the end of Book 2 as a result of Unalaq absorbing Raava's essence that causes Korra's connection to her past lives, feeling it ignores that spirits cannot be killed.
