Honestly, you could probably make the case that any fictional character ever is autistic. It's kind of like how a lot of people diagnose themselves with OCD just because they like seeing things in patterns and dislike seeing the pattern broken; a lot of the symptoms of autism are difficult to distinguish form normal human behavior. Autistic people have "special interests", but almost everyone has some kind of interest that they fixate on. Autistic people have difficulty understanding social cues, but everyone makes dumb communication errors.
