If Robin Hood was not a film about anthropomorphic animals would Marian have become a Disney princess?
The two things holding Marian back is that she is an animal and she is from a less popular film. She has all of the qualities of a Disney princess acting very much like typical Snow White archetype. She is actually royal unlike most unofficial princesses like Jane, Mirabel, Asha, Esmerelda. She is from a classic fairytale too. The other problem is Robin Hood is more of a ‘boys film’ like Hercules is which holds Meg back.
But hypothetically even if she didn’t last, at the beginning of the brand do you think she would have been considered like Jane, Esmerelda, Alice and Tinkerbell were?
