More than just one protagonist, though, she stands in a line of female main characters (not always lead or protag, actually) who start off as just intelligent, and develop into both intelligent and strong female characters, a bit like Hermione Granger from the HP series: these ladies began with some kind of growing to do, and did that growing through painful events, but grew, emotionally and personally (courage, committment, etc) to become much stronger than they started off the books or series, like:
Susan Ivanova from Babylon 5, or Eda from Sihirli Annem, or Nazli from Yabanci Damat all began as less than fully confident, but all very promising, intelligent, and self-directed young ladies, who had to learn to be more assertive, culminating in either marrying the person whom they chose (rather than their families chose), or by snatching victory from the jaws of death, or in the case of Amelia, deliberately walking into the possibility of the worst death known (an Auto-da-Fe) in history, for the purpose of making her point. (ok, yes, you could argue that Delenn does this in B5’s Circle of Fire, but watch the Ministerio del Tiempo episode, and you will see that it is rather different, and also Delenn arrived on B5 as a mature leader, where Amelia began as a novice leader).
These are the examples of critical thinking, emotional growth, and self-confidence that young girls need to see as early and as often as possible to grow into leaders able and willing to stand alongside men and make this world a more just and humane place for all.
(9th of June edit: these ladies all learned to use cooperation with their allies, and even understanding and forms of NonViolent Communication with their enemies, to accomplish seemingly impossible goals: worth learning in various languages to share with others as I aspire to become an excellent teacher, like all of these role models!) -Shira, 9 June, 2016
