Basically, I wanted to show a few Twilight fans why having faults is a good thing. This is sort of like a game. You list three personality flaws that you have and list characters from any book that share the same one. Than you compare those characters to anyone from Twilight who you feel is a Mary-Sue. I'll start it off :]

My Flaws:

Hubris shared with Annabeth from Percy Jackson.
High Temper shared with Harry Potter from HP
I don't let people know to much about me (mysterious?) even when I should - Gandalf from LOTR and Dumbledore from HP

Annabeth is really smart and she's always there for her friends. Although she thinks she can create a better world, she's loyal and kind. Harry is brave and would do anything for anyone. He cares deeply about his friends. Yes, he has temper problems, but he knows when to think logically and calm down. Gandalf and Dumbledore both are always stessed andl live in a worry-filled world and they tend not to tell people much about themselves or of anything dangerous. Although they do this, they still saved their world from turmoil. They trust people deeply and both believe in second chances and equility.
Now, these characters, which these personality flaws have achieved a lot in their lifetime, but Bella - being perfect - has never done something so great. She's perfect in everyones eyes, yet she hasn't done anything astounding. Most of the time she has depended on Edward.
Why would characters that have critical flaws be much better and achieve more than Bella? Hm, I wonder ...
