One of the four or five characters in
the Twilight Saga that isn't a Mary Sue and/or Gary Stu. She's described as pixie-like throughout the series, with black spiky hair, pale skin, (obviously, she's a vampire) and she's the smallest
family member. She was one of the Cullens that wanted Bella to remain alive in Twilight when the family argued about whether or not to kill her when Edward saved her life in fear of exposure. Her mate is
Jasper Hale, another one of the non-Gary Stu characters. She was changed by a vampire who loved her in her human life (which she doesn't have any real recollection of), who was killed by James (the one who tried to kill Bella in the first book). Her full human name was Mary Alice Brandon.
