Twilight Sisters

James is one of the most lethal vampires around. He feeds off of humans and enjoys tracking humans that have drawn the attention of other vampires. James was in Biloxi, Mississippi sometime around 1919 or 1920 and came upon a vampire who worked in a mental institution and had grown fond of a young, female patient. James made it his task to kill the girl, but before he could reach her, the other vampire changed the girl, making it useless for James to kill her. That girl was Alice Cullen.
In 2005, when James sees that Bella is being protected by Edward and the rest of the Cullens, he instantly wants to kill her for the sport of it. He eventually sets a trap for Bella in Phoenix, drawing her out of hiding by using her mother’s voice as bait. He wounds Bella almost fatally, breaking some ribs, her leg, and a cut on her head. He also bites her hand, sending venom into her system.
When the Cullens arrive and find Bella in such a state, Emmett and Jasper grab James and rip him to shreds. They then proceed to burn the remains, ensuring that James never harms another living soul again.
