Are you worried that one of your characters is a Mary-Sue? Well, if that's the case, you can take the Mary-Sue Litmus Test. The higher you score, the more of a Mary-Sue your character is. I should remind you that the test is no guarantee, and only serves as a guideline, an aid for character development, if you will.
Have fun testing your characters! Perhaps, when you're done, you could share your score?
(Then again, when in doubt, I checked yes.)
