Well, considering that there are eleven "official" Disney princesses (and a crap ton more that are unofficial), we've forgotten about a lot of them. These are just the most recent.
Yeah yeah, she's a queen. But people need to get that they're called that in the sense, not of their stories, but of the Disney kingdom. They're all pricesses there.
I find fault with that, because there are also queens at the Disney parks, and there are characters who are not princesses at all. The official lineup does not include Elsa. She is only considered a princess because is a woman in a Disney movie.
Bottem left is Rapunzel, she is from Tangled. Bottom Right is Elsa, sister of Anna (left upper corner) from Frozen. Right upper corner is Merida, from Brave.
Modern Flynn Rider? Yummm
