I've never seen the last four on this list ^ (Tiana, Rapunzel, Merida, Moana).
I pick Belle, because I'm a lot like her. We both read a lot, we're devoted to our father, we speak French, and we're afraid of falling in love with monsters. Our hearts are in glass cases, like the bell jar. We also personify inanimate objects by giving them names. She has great clothes and she learns how to love in the end. None of the other princesses learn to love. They just love foolishly, or they don't love at all.
I can relate to the townsfolk calling her "dazed and distracted" or "strange and peculiar" -- with a "dreamy far-off look" when her nose is stuck in a book.
Shouts out to Mulan who is also really cool.
One of my favourite animated heroines is Anastasia, but she technically isn't Disney.
