A Mary Sue is an idealized character meant to be the Author Avatar (a character who shares traits with the author like name, appearance, beliefs, etc.) or a self-insert character for the reader to live through. Common Sue traits (note, having a few of these to a degree doesn’t necessarily make a true Sue):

-Exceptionally popular/gets lots of attention, even if the Sue is *supposed* to be shy, anti-social, or socially awkward. People are drawn to her, her advice is great, and she’s trusted fairly quickly.

-Only people who challenge or dislike the Sue are portrayed as mean, stupid, or villainous (and usually get a comeuppance)

-Has no real flaws, or ones that are meant to be endearing and relatable (popular ones are clumsiness, temper, awkward, and stubbornness) that are justified by the author or not even intentionally written. These ‘flaws’ will ONLY help her, never hurt her because she’s always right. (For example, she’s rightfully stubborn against something bad or she loses her temper on someone who deserves it.)

-She doesn’t have to suffer consequences for selfish, bad, or reckless behavior

-Exceptionally beautiful, often with exotic traits like unusual coloring meant to make her stand out physically.

-Magical tools/weapons

-Magical abilities/traits like wings, healing factor, immortality, etc.

-Unusual pet(s)

-is a Woobie (has a tragic past or crappy life) but is still perfect/likable despite what happened.

-Exceptionally talented or good at things the author deems good. The Sue might be bad at things the author considers stupid (girly things like sewing, fashion, etc. but good at “boyish” stuff or things outside the norm like fighting, reading, or weapons are common). Even if the talent/skill isn’t realistic for the time period (like being a scholar or warrior when you're a medieval peasant, for example).

-Usually or always get their way even when she’s actually in the wrong. Never gets called out for being wrong, but if they do, the person calling them out is portrayed as a jerk (see above). If she does do something wrong, she’s remorseful and is instantly forgiven.

-Good fashion sense, even if she’s meant to be a rough-and-tumble type or one who doesn’t care about clothes and is effortlessly attractive. Male characters will often comment on how they like this about her.

-Is a Special Snowflake who “isn’t like the other girls”. Something unique, physically or personality-wise, sets her apart from everyone else.

-A Friend to All Living Things. Animals like her and she loves everyone and forgives their imperfections. Willing to protect or risk all for someone she just met recently.

Summed up, the Mary Sue is meant to stand out from everyone else in a good way and is generally portrayed as the ideal character/role model, very cool and universally relatable, usually. Anyone who dislikes the Sue is the one portrayed as in the wrong.

I think Merida is the least like one.

And Jasmine. Then Merida.

I once put some of the DPs on it - Snow, Cindy, Aurora, Belle and Rapunzel - and she was the only one to have 50+ (Mary Sue). Still, I don't think she's a Sue, just the cloest to it.

Oh... sorry, I misread the question! Well, let me think. I was talking about Rapunzel.

Definitely Merida. While she is OBVIOUSLY meant to be "not like the other princesses" and sucks at traditional stuff in her own movie, she's so far from being idealized it's not even funny. She's relatable but has very human flaws and reactions not everyone likes about her. She's pretty imperfect.

Difficult, but I would say Merida. Though she has exceptional skill with weapons, which seems in line with the Mary Sue character traits, it's basically the only thing. She isn't particularly well liked or beautiful, and she pays the price for her actions.

She's far from it, in a good way.

^Agreed.

Forgot to add, eliminated by comments!

she's the opposite of a mary sue, too flawed, then jasmine.

Maybe Pocahontas next..

Never seen her as one

She is the perfect flawed princess! And that makes her amazing!! ^_^

I thnik Merida is a bit of a author avatar for Brenda Chapman, we are supposed to admire her tomboyishness. But she would be probably next for me.
