Neither of which I would ever reread for leisure or fun. But just because I don’t like them, doesn’t mean they don’t have a place in the timeline and are a part of the canon. I watched as this guy took every argument I had heard since the decanonization and had rebuttals for every one of them, all by using direct quotes from George Lucas himself and the folks at Lucas Licensing, including citations and all.
I talk with a couple of Japanese users on social media and I was wondering what other words can I use to say "Oh, I have this theory", or "I imagine this and that about those characters". Community Headcanon always comes with risks- you're putting your creation out there and no matter how detailed of a vision you shared, the moment you invite others to incorporate it into their vision, it will morph. Sometimes for good, sometimes into something unrecognizable. Some communities credit the original creator headcanons generator for having a "veto" rule, but the best of these can outlive the original author's participation in the game, leading to no clear "head." There's also the risk that it'll go nowhere. Sometimes, your idea isn't picked up or used by anyone other than yourself... The biggest issue with subjects like this isn't necessarily the headcanon aspect.
The books and writers that are considered as belonging to the canon are almost always the subject of argument and tend to change with the times. The future of character headcanon generator generators lies in the integration of AI and machine learning technologies. These advancements can lead to even more sophisticated and nuanced character profiles.
Ultimately, official canon is much smaller than the people who throw the term around like to think it is. Canonicity is limited to that which has actually been described in the source material. Especially in groups of writers, it boils down to what the writers specifically need to worry about for the purposes of the ongoing plot. Now don’t interpret this as me saying you must like or even read all of the EU. I absolutely detest Barbra Hambly’s writing style and the Invasion comics were a legitimate pain for me to get through.
Now obviously, in canon, this gets more complicated as time goes on and she takes on a more feminine appearance. However, having an alternate universe setting or a canon divergence setting where Haruhi actually comes to terms with her gender in a non-cis way is certainly a viable choice even without other trans characters for balance. I can certainly also see this going wrong if not well-considered, such as if someone goes the route of Haruhi being closeted. Often, when it comes to stories about closeted trans people, the story only revolves around them struggling with their transness or taking the leap to come out as trans. This goes back to the struggle narrative/trauma porn. It’s definitely a way for a trans writer to work through their own feelings about it, but I generally urge cis writers to stay away from anything approaching that.
