Alice C.

Alice Cullen is a vampire born in 1901. She has the unusual ability to see into the future. She cannot see her adoptive niece, Renesmee, in her visions. She also cannot see the La Push Shapeshifters. Because of her ability, Alice was confined to a mental hospital in the 20's. There, an anoyomous vampire changed her to save her from James, the vampire who was tracking her. James killed the other vampire instead. In 1948, she met Jasper Hale, a former Confederate Army soldier. He had been changed to a vampire by a venomous vampire named Maria. In the 50's, her and Jasper joined the Cullens. When Bella was attacked by James and lured to the dance studio in Twilight, Alice killed James by twisting his head off and burning his body. WOW.

Bella Swan
Bella Swan is her adoptive sister in law. She is one of the Cullens who voted in favor of Bella becoming a vampire.
