wonder woman for sure. I wanted that wonder woman barbie so bad when I was little, every time we went to the store I would stare and stare. Never got her. That's it, I'm off the e-bay!
Well, this may not count as a superhero, but the first one that came to mind was Sydney Bristo of Alias. My DD has me watching all the seasons and I'd love to be able to kick like she does!
