Eiko

Okay, I think this is pretty appropriate for my first submission.

This is Eiko Magami from Project A-Ko, which was the movie that first got me hooked on anime. I like the retro looking "S" on her top. If you're familiar with the movie, you'll get what the superhero underwear is about.

2012 EDIT: Okay, I had originally titled this "Eiko Tyler Moore." It doesn't have anything to do with Mary Tyler Moore, but I guess the way she's jumping for joy reminded me of when Mary Richards throws her hat up in the air. Looking at this again, though, I think title just adds an unnecessary layer of confusion to it, so I'm simplifying it to just "Eiko."
