My favorite female character: Luna Lovegood.
She rounds out my top three favorite characters in the series, alongside Snape and Hagrid.
The thing that says the most about Luna to me is that Rowling introduces this character in book FIVE. Without much time to make an impression, boy does she make one. Luna is one of Rowling’s most inspired characters. It isn’t that she isn’t, as her nickname says, loony; most of the time she makes little to no sense but she is supremely confident and does not remotely try to fit in or hide her odd nature. Even when people make fun of her, she does not seem to care. She rounds out the main characters so well and I think the series would have been sincerely lacking without her.
