Alright, just something I figured I would post for your (any my) improvement. This isn't a contest in any way; it's supposed to help give you a guage on how much revision the character could use. Just a note, some great characters will still peg high on the test.
If any of you don't know what a Mary Sue is, just think of Wesley Crusher (of Star Trek fame) and you have a prime example. Typically found more in literary works, they're characters quite dull and over-powered.
Case in point: Muramin scored a 46, which would be considered dangerously high on the first test above. She scored a 20 on the second link. As you can see, different tests reveal different results. Just a note, a lot of things are subjective. For the tests to work, be in favor of clicking something if it's a "Maybe…" or a "Well, s/he could have..." type of thing.
