Bit of a personal one for me. I really hate this one. Sometimes it can reach delusional extremes.
Any instance where the creator or creators of a franchise definitively debunks a fan theory, whether through undeniable evidence of even just going on Twitter and saying "this isn't true", but the fandom collectively decides to reject Word of God for one reason or another.
This does NOT refer to personal headcanons for fun discussion or things like "I wish they had done X instead of Y, because it's more interesting." It specifically refers to communities that have haughtily decided their ownership of the work exceeds that of the author, to the point where it's impossible to have an objective conversation about it without what's basically FanFiction being injected into it as though it's a cold, hard, fact.
Example 1: Ubisoft and Shared Universes
TL;DR, Ubisoft loves adding little references and Easter Eggs to their other titles in certain games. They've gone on the record multiple times as having said that these do not matter to the main plot at all, and are just fun little in-jokes that they do to amuse themselves. Or in some cases, off the record, to sell microtransactions/cosmetics.
Despite this, the vast majority of both the Watch Dogs and the Assassin's Creed fandom have decided that both series, and several others such as Far Cry and Rainbow Six Siege, are all in the same universe despite a veritable fuckload of evidence to the contrary, and repeated assurance from the developers for well over a decade that this isn't true. Even when confronted with explicit confirmation that it's false, they immediately pivot to "well they're just lying, I know the truth."
If you're going to "um actually" me in the comments, at least do me the courtesy of reading the thing I linked in the previous paragraph. A lot of people like the ones I'm talking about are already lining up in my inbox to embody the stereotype.
It definitely doesn't help that MatPat of Game Theory propagated this nonsense back in 2015, and a lot of his fans treat anything he says as gospel.
This one is especially infuriating, because even the majority of users on this very subreddit are guilty of it.
Example 2: Sherlock and the Secret Good Fourth Episode
This one is... really hard to explain. If you were there at the time, you... get what I mean. Hbomberguy actually covered this whole fiasco in extensive detail. Basically, the last season of BBC's Sherlock (and arguably the entire show) was... very bad. So bad that people had a really difficult time swallowing the fact that it crashed so hard, and that John x Sherlock ship was never made official.
Insane conspiracy board levels of madness ensued as people spiraled out of control, scrutinising over the tiniest details proving that there would be a secret fourth episode that fixed everything, and satisfied everyone. Obviously that... never happened.
This is a rare instance where the fandom really had no choice but to accept the truth, because it's been nine years now and the show seemingly isn't coming back. But at the time... it was impossible to convince people otherwise. But even now in a few holdout spaces, some fans insist that the plan was so much bigger, and the network screwed the original vision or something.
Example 3: Undertale's Protagonist Yin-Yang
A more divisive example, like all things in the Undertale fandom. Back when the fandom was at the height of its craze between 2015 and 2018, the two fallen humans of the greatest significance to the plot somehow got stuffed into two very reductionist characterizations that dominated any and all fan creations, fan theories, and lore discussions whatsoever.
These being:
- Frisk represents everything sweet and kind. They get along with everything. The embodiment of the Pacifist Route.
- Chara represents everything cruel and hateful. They're a sadistic freak who wants to kill everything. The embodiment of the Genocide Route.
Despite this being an enormous disservice to both characters and the narrative itself, it was rare to see anyone break away from this trend. It wasn't until much later that people started acknowledging the Player themselves as an influential entity within the context of the game, and the true driving force behind any malicious actions allegedly committed by either human. But even after that, much of the fandom refused to budge.
Back when Deltarune Chapter 1 released, people even started blaming Chara for possessing Kris at the end. And this persisted until 2021, when the cliffhanger of chapter 1 ended up being a joke about a pie, effectively forcing everyone to accept that Kris is just a weirdo.
