I suppose all superheroes feel the same social separation we all do, especially if they have to hide behind secret identities.
One superhero though, who may (in my opinion, at least) display all the symptoms of AS is Batman, at least Batman as portrayed by Michael Keaton in the Tim Burton classic. Consider: as Bruce Wayne he throws parties but doesn't really mix with the guests, and has no idea of the value of the money or attention he gives to them, and he has extreme trouble even talking to a woman he that wants to like him. He is very good with machines and gadgets, and with abstract thinking.
Also, as Batman, he has:
Limited interests or preoccupation with a subject to the exclusion of other activities;
Repetitive behaviors or rituals;
Peculiarities in speech and language;
Extensive logical/technical patterns of thought;
Socially and emotionally inappropriate behavior and interpersonal interaction.
(The last bit was copied per se from a description of AS on Wikipedia.)
