Mulan, Ariel, and Pocahontas. I feel like Jasmine and Belle could've been better developed.

Ariel -- She doesn't really change at all in the story, which is too bad. She kind of needed to change, but she remains as selfish (imo) in the end as she was in the beginning.

Belle -- She doesn't change either. Actually, she changes a bit more in the musical. However, she doesn't need to change. The Beast is the one who needs to change and develop, and Belle helps him.

Jasmine -- She changes a little perhaps, as she is now content to live in the palace because she has found her true love. However, she doesn't change much because she isn't the lead character and doesn't have a chance.

Pocahontas -- She doesn't change much either, but I do need to rewatch her movie. She basically just figures out what to do instead of being unable to decide, but she doesn't have any real character development.

Mulan -- She has the most character development. At first she doesn't really believe in herself and is socially awkward and clumsy, but then she gains some confidence and can speak to the EMPEROR without too much nervousness, where before she was nervous to speak to a Matchmaker.

Without a doubt

Definitelyyyyyy!

Obviously

its so obvious.

then Belle

Definitely.

Definitely not Mulan. She was developed, but not well-developed. Her character development was too rushed and unrealistic, imo. Pocahontas and Jasmine does developed more subtly, but better.

Def

She has so many nuances and layers and different sides to her character, as well as making great character development throughout the movie. I could analyze her character for hours.

Most definitely.

she's the only of them given explicit flaws that need to be worked out as part of her character arc, so yeah
