In all seriousness she kind of reminds me of Link for some strange reason.
On the other hand if we are looking for Disney characters who are definitely very Identical to Link and Zelda I would have to say that would probably go to Taran and Eilonwy from The Black Cauldron.
Unrelated: I find it really awesome that The Screenplay to Brave was done by the creator of Sam & Max Steve Purcell.
