Gordon Freeman. It's a stretch, given that he's not even an actual character, just a named shell, but I see more fanwangledangles about him than anyone I can think of, and it just annoys the shit out of me. "Hey look at Gordon Freeman, he's a nerd that saves the world!" No, you're told that he's a nerd. For all you know his degree is a fake and he's only doing menial labor.
