Here's Caroline's version of the RGB Mary Sue/Gary Stu Litmus Test:
( the Mary Sue Litmus Test writers guide can be found here:
missy.reimer.com/library/marysue.html )
> 1. Is your character named after you? How about a nickname, or a
> Chat/List handle? The name your parents should have given you?
>
> 2. (TWO POINTS) Does she have an exotic first name or is it spelled
> unusually?
>
> 3. Is there a striking physical resemblance between you and your
> character?
>
> 4. If there is not a striking resemblance, does she look like you
> would *like* to look? (Come now, be honest...)
>
> 5. Is your character exceptionally beautiful or have a unique eye or
> hair color?
>
> 6. Is she introduced to the reader in the first chapter? (TWO POINTS
> if it's the first paragraph)
>
> 7. Is she your age, or the age you would like to be/like to return
> to? (TWO POINTS if she is more than 5 years younger than the
> Ghostbusters are in your given fic)
>
> Personality traits/talents/family tree/etc:
>
> 8. Does your Character have a very similar personality to yours?
>
> 9. Does she have some amazing talent, like knowing more about the
> occult than Ray, or having more PhDs than Egon?
>
> 10. Is the character so charming that everyone in the fic, except
> for the villain, likes her--and even he or she will be won over in
> the end?
>
> 11. Is she accepted into the group very early on?
>
> 12. Does everyone seem to have a very special and unique
> relationship with her character?
>
> 13. Does she have a job or profession that you have or would someday
> like to have? TWO POINTS if the job is exotic (ex. foreign spy), but
> does not figure into the plot.
>
> 14. (TWO POINTS) Is she an Orphan?
>
> 15. (THREE POINTS) Does she have or acquire some horrible terminal
> Disease and/or traumatic injury?
>
> 16. (5 POINTS) Is she Egon, Peter, Ray, or Winston's unknown lost
> Sister/daughter, and was separated from them at birth due to some
> Dickensian tragedy? (If you qualify for 14,15, AND 16, you can just
> stop right now. It's a Mary Sue.)
>
>
> Ghostbuster-specific questions:
>
> 17. Does she encounter the Ghostbusters via Time travel, dimension-
> shift, Quantum Leap, or any other temporal anomaly, automatically
> being regarded as friend rather than foe?
>
> 18. Does she become a member or an honorary member of the
> Ghostbusters?
>
> 19. Is she the cause of a love triangle among herself and two (or
> more) Ghostbusters?
>
> 20. Does she start dating your personal favorite Ghostbuster? (TWO
> POINTS if she dates Peter, and is the impetus for Peter abandoning
> his bachelor ways and settling down)
>
> 21. Does she play an integral part in getting Egon and Janine
> together? (TWO POINTS if she gets Egon to publicly show his
> affection for her)
>
> 22. Is she the cause of a dramatic personality shift in one or more
> Ghostbusters? I.E. Egon becoming emotionally open
>
> 23. Does she go on busts with the others? (TWO POINTS if she can use
> a proton pack with no trouble first try)
>
> 24. Does she spend more time at the firehall than Janine? (TWO
> POINTS if she lives there)
>
> 25. (5 POINTS) Does she save one or more Ghostbusters from certain
> death, damnation, and/or demonic possession, OR vice versa?
>
> Tote 'em up folks... 43 points total (assuming you weren't
> immediately invalidated by having 14,15, and 16 together...)
>
> 1-10 Probably just fine, but keep an eye on things. Note: I would
> consider the Soap series to be in this range, so you may still have
> a good story on your hands! Just tread carefully...
>
> 11-20 Getting a little more suspect. Might want to consider if all
> Mary Sue-ish traits are absolutely integral to character/plot.
>
> 21-30 Ok, we're definitely in Mary Sue land now. It's probably time
> for some serious rewrites. Before you despair, keep in mind that
> there are several excellent Mary Sue-esque fics out there. They take
> talent and practice to write, however, so tread carefully!
>
> 31-43: Hey, Autobiographical fantasies are fun to write--I'm not
> arguing with that! They can be great catharsis, daydreaming, and
> possibly good therapy. They can even be good practice for your other
> writing, if you take what you've learned and try to evolve into a
> better writer (I am assuming here that this is the ultimate goal of
> all of us at RGBfanfic). However, you need to really sit down and
> think if this is something that should be 'published'. At the end of
> the day, if you post this story, and somebody utterly trashes
> everything about it, Plot, Characters, writing style, even spelling
> and grammar, will you be merely irritated at their poor taste in
> literature, but possibly take some suggestions to heart? Or, will
> you be utterly crushed, because you've invested so much of yourself
> into the tale that a criticism of your story feels like a criticism
> of YOU? If #2 seems more like your situation, it might be better if
> you kept your story to yourself, and maybe a few close friends.
