To start Mary-Sue is thrown around not only on the disney Princess club, but almost everywhere whenever it comes down to the disney Princesses. The correct definition to Mary-Sue is a perfect female character who doesn't try to be perfect, but naturally is. Like a Renaissance Man, yet doesn't fail at least while trying.
Some have been saying Classics, or Walt Disney's princesses, Belle and Rapunzel are Mary-Sues, plus more. I very much disagree.

The most common areas to be considered Mary-Sues are:
Snow White
Cinderella
Aurora
Ariel (on the occasion)
Belle
Rapunzel

There are so many reasons they are not Mary-Sues. That word can just sicken me at times, it's unnecessary. Though cinderela and Aurora are both balanced from Mary-Sue and to just a beautiful young woman.

Snow White
A user on here *coughSilverrose1991* has been going through a manipulative boss rut with Snow White, which I admire and agree with. She isn't just a pretty face, not JUST SWEET, she contains much mais personality. Though that isn't the point. Under that sweet adorable face, lay a manipulative boss, who runs the joint like a business. I just wanted to get that out, she isn't perfect, nor is she dumb. She can sing (to those who admire her high-pitched voice), dance, she's pretty, sweet, a manipulative boss, yet because she's talented, that doesn't make her a Mary-Sue. She's plenty filled with flaws. Nobody is perfect, even a cartoon.

Ariel
On the rare occasion, she can be. Big eyes filled with lashes, super slim figure, beautiful voice. I think differently, she dumped her family, for a guy she didn't know. She showed affection, "but how will I ever see my family again," or something like that. But it's the decision that marks its way through. She is pretty selfish, I must admit. But for now I'm disliking her, I'm bound to change my affection for her. Anyway...she acts like she has no rights, she only can't go to the surface and had to show up to whatnot, otherwise, she has privileges. Yet though she can't speak, she doesn't do anything to show Sebastian how much she loves him for what he's doing, only a kiss. When Sebastian nearly dies and Sebastian states, "I hope you appreciate what I do for you," or something like that, Ariel ignores him and goes to bed. Plus, she pushes her friends aside when they want to help, but when they don't feel like helping her, she plummets all her problems onto them to fix as she makes mais messes. I'm starting to spit out hate rather than love. Sorry for that, but selfishness is not found in a Mary-Sue.

Belle
Some say Belle is completely perfect-or too perfect, while others point out she's a snob, and sometimes it's the same person. Nothing mais than that irritates me, you push someone down for something, yet they do something to prevent that other thing you still are upset. That made no sense. Anyways, Belle is 'perfect' and someone complains for that, then she's snobbish and then you complain for that. The snobbish part prevents her perfect-ness. It's being picky at times, you want something, you get it, but not the way you want it. This still makes no sense, right?
Well, some of you know I've made a Merida defense artigo on my older account, THEDisneyFreak. I said that Merida had everyday monitored and was forced to marry a stranger expected to be happy about that. If you were in her place (ahem Merida complainers) you would just sit there and smile. 'Yay I'm marrying a suitor!' At the age of sixteen, to a stranger. Happy? No.
This relates to Belle's situation in a way because Belle, like I said/typed, is a snob, then you change your mind to her being perfect, either way, you're not satisfied.

Rapunzel
Okay, judging from my ranking of where she is on my list, my username, my icon, and the fact I watch enrolados twice everyday (very unnecessary information) it hurts for me to say out of the ladies I've listed, she's the most Mary-Sue like. Yet she's far from it. She beats the others with the ability to do EVERYTHING. Which I've heard multiple complaints about before, but she has been practicing for what-her whole life? She's bored all the time, which holds a lot of time for her to do things, start up the chores, sweep 'till the floors all clean, polish and wax do laundry and mop and shine up, sweep again, then read the books, or two or three, and continuing. She has the most talents out of all of the 'Mary-Sues' but she just had the most practice and free-time. mais or so like I mentioned, a Renaissance Man. She must have failed before, plus she is a very talented artist, which most Renaissance Men were best at (Michelangelo & Leonardo da Vinci).
