11. Batgirl
In Batman and Robin, Barbara Wilson was the niece of Bruce Wayne's butler, Alfred Pennyworth, who donned a costume of her own and, calling herself Batgirl, came to the aid of Batman and Robin in their fight against Poison Ivy, Bane and Mr. Freeze. She defeats Ivy on her own, after the villain had tried to use her pheromones on Batman and Robin, and teams up with Robin to defeat Bane. Looking gorgeous in a tight bodysuit that really showed off Alicia Silverstone's curves, Batgirl kicked some serious ass using nothing more than a high level of skill. Bizarrely, the sexy suit she wore was designed for Barbara Wilson by her Uncle Batman's butler Alfred Pennyworth which is a little bit disturbing and creepy when you actually think about it.
