Is Your Original Character a Mary-Sue?
A Mary-Sue is an original character who is invincible in most ways possible. They are often immortal, have good looks, etc. Some people call male overpowered characters Gary-Stus, but personally I like calling them Mary-Sues, too. ;)
If you are worried that your original character is a Mary-Sue, or perhaps someone told you they are, I suggest you take this quiz. Are you a good writer? Have you avoided making a Mary-Sue? It's time for you to find out!
