I feel like Reagan Ridley having PTSD and autism is pretty much just canon, but fuck it, I’ll drop it here anyway.
I've seen it suggested that Hetalia's France has histrionic personality disorder, and he does fit some of the criteria in terms of being melodramatic and using sex/nudity to draw attention to himself. Not sure if he hits enough of the criteria to count but I could see it.
Krusty the Clown was raised as the son of a rabbi but is still illiterate - I theorise this could be caused by really bad dyslexia.
APH Russia seems to have stunted mental/emotional development and possibly age-regression; he uses "boku" pronouns in the sub, which are usually used by little boys, gets strongly attached to objects, reacts very badly when things don't go his way, and an offscreen person who is heavily implied to be Stalin is referred to in the dub as Russia's "teacher" instead of his "boss" which all the other nations call their leaders.
I'm not familiar with the character, but it's worth noting that "little boys usually use 'boku' pronouns" doesn't mean "only little boys use 'boku' pronouns". (I had a conversation with my Japanese tutor just the other day where both of us used boku, for instance.) It's a pretty common choice of pronoun for anime characters, including adults!
Right, even within Hetalia itself there's quite a few characters that use "boku" while occupying the same nebulous "young adult" range that he does!
Yeah, I wouldn't use it as sole evidence but it fits with his behaviour as sort of an additional thing.
Bringing this post back because I got to this same scene and had the exact same reaction. Not even just the narrator going "AND THEN THE PRINCE, WHO DID NOT KNOW HOW TO DO ANY OF THIS, FUCKED IT UP, AGAIN," but also the way that you walk into the room and like 20 interaction points suddenly pop up and he goes "Oh no..." and then you examine like 5 of them and he just gives up.
To continue on the subject of Zagreus… In the postgame, the narrator handwaves away your successful escape attempts with ever-more-contrived last-minute deaths. One of them is this:
been reading the Stormlight Archive, I'm about 8 hours into Oathbringer. Shallan is giving big DID vibes. it seems like canon is gearing up to handle this in a questionable way? but we'll see how it goes, I'm only 15% through the book.
So, not that I wasn't already of the opinion that Dr. Mortum from Fallen Hero has ADHD (and not just to the extent inherent in the mad scientist archetype)... But the author just released a Patreon extra told from Dr. Mortum's POV, and good god that is the most ADHD thought process I have ever seen. It's beautiful. Increasingly wondering if this reading is just straight-up canon, tbh.
Regarding miscellaneous brain weird headcanons, I’ve actually kind of headcanoned Michael Myers as having a photographic memory sort of thing and that’s one way he learns things quickly. I mean, given that the novelization did say that he learned to drive just by watching Loomis do it (which I sure as shit can’t do; then again, my driving instructor said I wasn’t cut out for driving because I was too careful on the road and she thought my anxiety disorder would make things difficult), I think that it’s not implausible that he’d just have a way of just learning things quickly that way. (Of course, even in the film, it doesn’t mean that he’s great at it; Annie Brackett definitely had her opinions on it. Not complimentary ones) And I also headcanon that Michael’s one of those child prodigy types, especially given that he learned so young. And naturally, Jamie, his niece, kind of has a little of that talent too, especially given how she gets his learning-to-drive-a-car instantly talent in 6. Like, 6 has problems, but I still think it has just plain wonderful moments, like Jamie learning how to drive a car instantly during her own escape. And the fact that in the Producer’s Cut, she manages to go neck and neck with Michael pretty well despite learning to drive for the first time. (I think even Michael would probably be reluctantly a little amused by the irony)
