I would have to go for Hero Sue, only because I would, of course, eventually beat the bad guys.
But you must understand, I love writing mockeries of Sues. I wrote a fic in which I was trying to be a Mary Sue - and failing dramatically.
I would be an angsty, tragic Sue, with a dark past, but who would try to cover it up. Cynical, angry, and very bitter, but very, very good at hitting the other side of the spectrum and bouncing off the ceiling. I'd have long, blonde hair ((wait...does that have to be a Sue trait? I've got it anyways...)) except that my hair would be either truely straight, or truely curly, instead of just wavy! My eyes would be emerald green....instead of just dark. And I would not wear glasses, no siree!
No one would fall in love with me though, I don't think I'd be that kind of Sue.
