Fictional Characters whom you think have Asperger/autism

[Aeolienne]

Karl from The Beach. Mainly because of his selective mutism, but also because it's unusual for Swedes of his generation not to have a good command of English, which suggests a learning disability.

 

[aspiewoman999]

robin from stranger things

 

[GrownupGirl]

Apparently Flick from Animal Crossing NH, because he's intensely interested in bugs and insects and has an introverted personality, but gets really excited whenever you bring him a bug.
Okay whatever, I think he's just goth/punk/emo.

 

[Laughingowl1975]

Uncle Quentin from the Famous Five stories is clearly an aspie, including his poor social skills, fixation on his interests, trouble organizing himself and dislike of noise.

 

[autism-and-autotune]

I think that maybe L but, at least, Near from Death Note manga has Asperger Syndrome.

"I'll take a potato chip...and eat it!!" *intense music*

 

[autism-and-autotune]

Tech from Star Wars Bad Batch was pretty much in-show confirmed to be an autism representation.

 

[soph21]

Autism: Abed from Community obviously, Newt from Fantastic Beasts also pretty obviously, Luna from Harry Potter, the siblings and Dad from The Mitchells against the Machines, Ash (or what was his name? ) from Fantastic Mr. Fox, Sherlock from the TV show, Farkle from Girl meets world (even if they say he doesn't), Casey and her parents and Paige from Atypical

ADHD: Barney from HIMYM, Tony Stark/Iron Man, Tony Gates and Paul Grady from ER (ok, that's really niche), Kimmy Gibbler from Full(er) House

 

[Iberata]

Eric Cartman from South Park series.
I've always considered he showed specific aspie traits.
