EDIT 3: 11/22/09 You guys are kidding me XD For goodness sakes, reaaaaad the liink here: [link] Every time I get a comment that reads "the one on the left is a Mary Sue because she has green hair and a power," I realize that they're not reading the description which contains this link: [link]
tl;dr: If 'special' traits fit in with the universe, it doesn't automatically make the character a Mary Sue. What if everyone else in Ami Machida's universe has green/blue/purple hair? What if everyone else has a cat power? Does that make her a Mary Sue? Not necessarily.
Please, spare me the time from having to point you BACK to the silly description and just take a minute to read the link. You know, the one I linked to a bunch of times up above. And the link here: [link]EDIT 2: 10/11/09 I suppose this is long overdue, but for those of you with confusion, here is an explanation on why I perceive the one on the left as not a Mary Sue: [link] For the love of god stop whining about it D:EDIT: 6/21/09 Okay, everyone, please chill with all the 'hay is my character a mary-sue!?11" questions. I get about 3 a day now and one thing you need to understand - I AM NOT AN AUTHORITY ON MARY SUES. This picture is a parody. Just for fun. The one on the right is obviously an extreme exaggeration of a stereotype and not the definitive definition for a Mary Sue. D:
Please full view. You won't be able to read the text if you don't.
For those of you who don't know, a Mary Sue, in a nutshell, is a fanmade character that is usually extremely beautiful, powerful, smart, talented, and in plain words, perfect in every way.
These characters tend to be quite a bother in fanfiction and role playing, since they simply can't be beat, and thus become boring.
Have any of you ever been rping, and come across a character who is like, " oh, well, that planet in the way isn't a problem *blows it up*"
Or, is like, "well, Vegeta and Goten and Trunks and Goku ALL have a crush on my character"
Yep. That's a Mary Sue.
So, for people who still don't understand, I made this little picture/diagram. Usually, Mary Sues have TONS of talents and TONS of powers, and no weaknesses.
