Oooh, interesting. I always did try to tell people that the Disney princesses as a whole weren't just the helpless crybaby dolls that pop culture seem to portray them as... in fact, the single Disney princess who is a helpless crybaby doll is Aurora, who literally does nothing in her own movie apart from getting cursed as a baby, falling in love as a teenager, and getting hypnotized by Maleficent into pricking her finger and falling asleep.
...I kind of want to play Aurora. Of all the princesses (with the possible exception of Snow White, who is clearly a kid and spends her movie playing pretend), she must have undergone the biggest transformation in order to become a warrior. Besides, since it was Merryweather's spell that transformed the princesses, and Maleficent was one of the antagonists, Aurora would have an extra personal involvement here.
