Good idea,
Elennar! The checklist! I had a plotbunnie that hit with a vengeance (and the bad thing is that it is too complicated to write quickly!) and it derailed my comic fiction and now threatens to derail much more. So, here goes with the Sue checklist, just to make sure there's not a danger of putridity in the works...but I seriously doubt it, as the only original characters are touchstones and not the main focus:
-the hero is a girl
No, hero is Pippin
-she has an exotic name
his name is Pippin (Mr. Peregrin Took!)
-her eyes, hair or both are an unusual colour
sea green eyes (oh, is that unusual-I don't think Tolkien specified, so I'll go with the Billy model!); hair is "almost golden"
-the writer’s favourite character falls in love with her
Well, my favorite characters are Frodo and Pippin, so no, Frodo does not fall for Pippin or vice versa
-she has all the good characteristics the writer would like to have herself
Well, yes, I'd love to be like Pippin in some ways!
-she has none or very few flaws in her personality: she is kind to everyone, brave, beautiful, sickeningly sweet…
We all know what Pippin's like!
-she often has immense supernatural abilities
Nope, just a sword of Westernesse and some really cool armor from Gondor! Oh, and he talks to trees...
-everything in the story is centred around her
not exactly, but he is the focus
-she makes other characters behave uncharacteristically
Oh, I hope not!
-she often sings (but not all singers are Mary-Sues)
Sing, Pippin, Sing!!!!
Do not make her royalty of any type.
Not royalty, but will someday be Thain of the Shire and a Counselor of the North Kingdom!
Do not have her die and have everyone cry over her loss.
Not set that far ahead in time!
Tortured pasts are forbidden.
Pippin? Tortured past? Tee hee!
As are mystery pasts.
No more mystery than the parts Tolkien left out for us latecomers to fill in!
Not a Sue.
I suppose I can continue writing now!
Cheers!
