Kida is one but is not official.

Elsa is like 21 or something, and is also not official.

No. I did not make this up. Source: According to Jennifer Lee, Anna is 18 years old in the film, while both Elsa and Kristoff are 21 years old and Hans is 23 years old.

wavesurf I just picked Elsa as an example because most, if not all, of the dps in the lineup are in their teens and I didn't want to use kida because I thought someone was going to make a comment like "I don't want her thousands of years old" or something

^Yeah. Kida bashing is infrequent...mostly because fans don't seem to remember she exists...like Eilonwy.

The reason I don't find Elsa appealing anymore, is because Elsa has already picked up the "adult perspective" that "certain things can't be done." As a ruler, with obligations, I'm sure she envies Anna, her sister, who has fewer responsibilities, if any. Elsa reminds me of Elinor. It's like asking me if I want Elinor in the lineup.... Um, no.

Not really. Besides, wouldn't older princesses be coronated at some point?

^there's princesses who don't automatically become queens when they reach a certain age. just look at the royal family in england

Honestly I prefer older/more mature characters to teenage ones.

Why not?

Ew no.
