I considered including Pocahontas as well, but these three come across as a lot more passive in my opinion. I'm honestly not sure who to choose...

I DON'T KNOW.
I guess all of them are passive.

Aurora or Elsa, in my opinion. All three are passive, but Cinderella can have her displays of proactiveness. But I'll go with Aurora, because at least Elsa runs away twice.

I have to say. Elsa is very reactive, but at least she's consistent in what she thinks she has to do. She wants to hide her powers. Failing that, she wants to stay away from people so she doesn't hurt or be hurt by them. Her people find out? She flees. Anna comes to see her? She makes a giant snow man to throw her out. Hans and Weaseltown guards come along? She flees, then fights back. She wakes in prison? She breaks herself out.

While definitely passive and reactive, she

Aurora... I can't really think of anything she takes the initiative on. She wants to meet someone but her "aunts" say no, so she dreams and waits for it to come true. Once it does, the only thing she takes charge in is telling him to meet her that evening in the cottage. After that? Nope. Fairies say she can't be with him? She runs to her room crying. They decide to take her to the palace, she follows. They give her a crown to become queen? She just cries. Maleficent bewitches her? She follows along. The fairies warn her, "Don't touch anything!" she pulls back. Maleficent orders her to touch it? She does.

I mean, good grief. When does she not just do what she's told? Even when she knows it'll bring her misery?

Tygers - The fairies warn her, "Don't touch anything!" she pulls back. Maleficent orders her to touch it? She does.

Aurora was hipnotized^^

we havent seen all of Elsa's personality so we cant say shes is passive for sure.

Or Cinderella. Elsa is definitely far lower on the scale of passivity than these two.

Well- she's cursed or asleep for a good portion of the movie.

I guess so.
