I haven't purposely given any, but now I am thinking about what the characters already have that might be flaws. Can 'Mary Sue' in and of itself be a flaw? That she is such a rule - follower but based on her own sense of right and wrong...she sees everything in absolutes. Also, can race be a character 'flaw'? If the story involves racial relations in the 1970s, and the character is a minority, is that a flaw? If the purpose of flaw is supposed to provide challenges to the character, I guess it would be? I hope that question isn't offensive. I am hopelessly new to this whole thing.
