To be honest, Odette I could go without (even if she does fit into the picture, being a very "classical" princess). But I'm kinda sad to never hear of Kida, Eilonwy and Megara (whom, whilst in the Disney universe we hear nothing of her heritage, was a Princess of Thebes in the Greek Mythology). They're some of the most strong, sassy ladies, and for me is on pair with Mulan and Jasmine in ass-kicking abilities.
