** It's been observed that Rico rarely talks and when he does, it's short, simple words, he is less intelligent than any of his teammates, he has a poor self control and has a fondness for dangerous things. It doesn't help that there's an episode where the other three penguins develop something called "pisces dementia" and act just as crazy (well, somehow crazier) than Rico. The way his co-workers treat him implies he may have some sort of intellectual and/or learning disabillity.

** A popular theory is that Jotaro Kujo is on the UsefulNotes/AutismSpectrum due to his poor social skills, especially at the start of the story, as well as his official description pointing out that he acts like TheStoic because he mistakenly assumes everyone else can figure out how he's feeling.

* Mashiro from ''Literature/ThePetGirlOfSakurasou'' is commonly interpreted by Western audiences as autistic, to the point that during the run of its AnimatedAdaptation, most English-language discussions would ''assume'' the viewer to take this position. This is mostly due to her IdiotSavant traits, as she single-mindedly excels in art of any type while nearly zero skills at everything else; not only does she have NoSocialSkills (which frequently interferes with her work as a manga artist), but at the time the story begins she has little common sense (which improves a bit as the story progresses) and all official material states she'll never be able to live independently. She even has quirks like being a PickyEater that viewers ascribe to sensory issues.

* ''WesternAnimation/TinyToonAdventures'': It's becoming more common for fans to theorise that Shirley the Loon is on the autism spectrum. While she appears to be antisocial and unusual to others, she has a much deeper attatchment to her special interests, being divination and spiritual theories, than other characters. There's also her frequently meditating between classes, which some have been keen to interpret as comparable to autistic relaxation techniques.

* ''Series/Numb3rs'': Charlie is a highly sensitive individual who responds to trauma by going into a HeroicBSoD, has some very quirky mannerisms (such as his Charlie vision), and is clearly a savant whose character is at least partially inspired by ''Film/RainMan''. This has convinced much of the fandom that he is on the autism spectrum.

* ''WesternAnimation/{{Amphibia}}'': Sprig having ADHD is one headcanon that's somewhat popular. Signs of this include his short attention span, a compulsion to touch or do certain things at times, and experiencing SensoryOverload at one point.

* ''Manga/DeliciousInDungeon'': Fans have noted that Laios shows many autistic traits, such as having a special interest (monsters and eating them), being bad at social cues, and coming off as weird to others (he has a history of not fitting in, both in his hometown while growing up and when he became a soldier and joined the army). Shuro, who Laios had considered a close friend, even tells Laios that he can't stand him because of his lack of social skills, an unfortunately common experience for some autistic people. Laois is understandably upset, but also confused as to why Shuro didn't just say something.

* ''Anime/HuGttoPrettyCure'': Homare shows signs such as [[TraumaButton jumping causing her to remember her failed figure skating jump]], her sadness, distancing herself from others and from figure skating, and a loss of interest in other activities (not going to school that often). Fans speculate that she has depression after her failed skating jump.

* ''Franchise/PrettyCure'':

* ''Anime/DeliciousPartyPrettyCure'': Fans commonly interpret Kokone as autistic, going off of the fact that she doesn't know anything about communicating to the point where she reads a book about making friends, and when she tries to do anything, she either overthinks or overdoes it to ridiculous levels.

* The mental stability of Achilles in ''Literature/TheIliad'' has been speculated on by readers, literary critics, licensed therapists, and psychologists. The biggest theories are that he either has Narcissistic Personality Disorder (grandiosity, easily enraged by slights, self-centeredness, and LackOfEmpathy) or Borderline Personality Disorder (impulsivity, extreme emotions, attachment issues, and almost dissociative rages), or a combination of the two.

* ''ComicBook/GastonLagaffe'': Gaston is sometimes perceived by readers as autistic, due to his lack of social skills (only Jeanne, Jules and Bertrand seems to like him), his passion for music and animals, and his genius when it comes to inventions. Also, he is speculated to be narcoleptic due to the fact that he is capable to fall asleep while standing.
