5. Princess Leia (Carrie Fisher), Star Wars (1977)
Princess Leia is possibly one of the most well known faces of film, and is definitely one of the coolest. A senator and the leader of the Rebel Alliance, Leia is spirited and tenacious and is more than capable of holding her own in a fight. She used her strong leadership skills to fight during the Galactic Civil War and many other subsequent wars, and became known as one of the Galaxy's greatest heroes - I think Princess Leia is more than deserving of being on the list of 10 coolest female characters.
