A Mary Sue or Gary Stu (male form) is often either a perfect or almost perfect character. They often appear in fan fictions and are sometimes based on the author themselves.

If the Mary Sue or Gary Stu is based on the author, they normally have qualities that the author wishes they had.
For example, they wish to be more popular or better looking.

@White_Teeth_Teen is my other account, I've only put poetry up recently on it but I am too lazy to take it down and post on here for the time being.
Thanks.
