You know, I've never thought about it before, but I'm pretty sure Rei from Neon Genesis Evangelion has Asperger's. She's socially withdrawn, for one thing, and highly intelligent. She doesn't seem to understand metaphors or jokes, and whatever she's doing, it always seems like she's just going through the motions. Anything outside piloting Unit 00 and doing what Gendo tells her doesn't seem interest her at all.
Despite this, I still don't like her very much. XP
