As someone with autism, I like to connect with characters that I perceive to be autistic, even though I don't know of many characters in any media who are both canonically autistic and done well.

I feel like I can definitely see Nepeta on the spectrum, but I've seen people make some intriguing stories and cases on Karkat, Dirk, Aradia, Tavros, even Equius on there too, and I'm all for seeing autism headcanons in media lol.

I feel like Roxy, Vriska, and Jake give ADHD.

A lot of this is a mix of personal headcanons and well done fanfictions other people have made that I think are interesting to think about.

I don't have any comments on other neurodivergencies or such since I'm not quite sure I should speak on things I don't personally have lol.
