A fork of Rural Dictionary
A term referring to a character in fiction who is unreasonably favored by the author. The character typically faces few conflicts between themselves or non-villain characters, displays a complete lack of seriously crippling flaws and weaknesses, and has their bad actions repeatedly forgiven or regarded as unquestionably good by the story.
That is of course what the term is supposed to mean, but over the years its use has become more and more broad and haphazardly thrown around that it has essentially lost all meaning. Characters who obviously aren't Mary Sues are frequently called them, while characters who clearly fit the description fly under the radar. Mary Sue has become just another meaningless term used as a covert synonym for something you don't like, the same way "unfair" is used for video games or "contrived" is used for movies.
Kid: "Have you seen the new movie that came out? The main character is such a Mary Sue."
Kid 2: "No she's not. Do you even know what that term means?"
A Mary Sue is a fictional character that is either too perfect or overpowered.
Rey from Star Wars - Episode VII - The Force Awakens is a Mary Sue!
A female character who is so perfect that she is annoying. The name originated in a very short Star Trek story that mocked the sort of female characters who showed up in fanfiction. It usually refers to original female characters put into fanfiction, but can refer to any character.
Mary-Sues are characters who are usually extraordinarily gorgeous, amazingly talented, unusually powerful, and exceedingly attractive to whoever the author has a crush on. They often possess ridiculously fancy and pretentious first names -- Angel, Raven, Jewel, Lorelei Bianca Julia Marizza Snape -- and are very, very annoying.
Mary-Sue is often abbreviated to 'Sue.' The male equivelant is either Marty-Stu or Gary-Stu.
Your Buffy fanfic has a problem. Her name is Alayne Lorelei Gemma Jeshika Shanna, she has violet eyes and raven hair, curves in all the right places, is more powerful than Willow and a better fighter than Buffy and Faith combined, AND Spike is in love with her. She's a total Mary-Sue, and she's really annoying!"
Mary Sue
n.1
A negative reference to a female character
commonly used by beginning writers in their Fan-fiction.
Most times, the "Mary-Sue" is based upon the author.
She is unusually perfect and more advanced, also befriends
or becomes romantically entangled with the author's favorite
character/characters from the series. Because she is more
superior than the other characters in the work, she mainly
becomes the focus of the fan-fiction, thus ruining whatever
the fan-fiction was about.
As stated above, the name of the character referred to as
the "Mary-Sue" does not matter.
n.2
A person who acts smug or superior to a friend or comrade.
n.1
"Cassandra was a Mary-Sue in DD's version of Harry Potter VI."
n.2
"Don't be a Mary-Sue, you wanker!"
A character in primarily fan-fiction or mainstream media such as movies and TV whose glorification takes priority over the story.
Guy 1: "Hey dude, you hear about that new Mary Sue?"
Guy 2: "Oh, you mean the new main character of the new Star Wars movies?"
A fanmade character that is perfect in almost, if not, every way. They generally are unrealistically attractive, virtually every character is their friend or has a crush on them, and are overpowered. Male versions are also called a, "Gary Sue"
It used to refer to a type of female character who is depicted as unrealistically lacking in flaws or weaknesses.
Now people use to refer to a "Female Character I Don't Like For Some Reason."
