In every story, the main character goes through a change. Who changed the most?

Then Anna. None of the others change much.

No question whatsoever.

Merida? Why? She is exactly the same at the end of her movie as she was at the beginning.

And Elsa. ^P.S. Tiffany88, were we even watching the same movie? I guess not.

*Agrees with tiffany88*

She goes from a spoiled, selfish brat to a mature young woman, not as much as she would if the movie was what it promised it would be! Yes, I'm going to be this bitter about being jilted until the day I die, I'll even be complaining about it to my grandchildren, though if I live as long as my great grandmother I'll be complaining about it to my great great grandchildren.

From a clumsy, no-account, perpetual screw up to the most clever, adaptable, resourceful, roll-with-the-punches-as-they-come Hero of China.

Merida and Tiana are close seconds. Their entire movies are about their changes of heart and values. Merida from a selfish, impatient, immature brat to a compassionate, mature young woman. Tiana from a serious, tunnel-visioned workaholic to a more fun, relaxed, family woman.

She is the most developed DP in my opinion. First she was selfish but then she became a mature young lady. She also apologized for her mistake so that shows that she really changed.
