Mary-Sue

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.
