The major antagonist of the novel Twilight, James is depicted as a merciless "tracker" vampire who hunts human beings or, in some cases, animals, for sport. Fellow coven member Laurent says that James is unusually gifted at what he does and always gets what he wants, though it is later revealed that a then-human Alice Cullen escaped his clutches some time ago by being turned into a vampire before James could attack. Unlike the Cullen family, he drinks human blood as his food source. Towards the end of Twilight, James is dismembered and set on fire (thus permanently destroyed) by Cullen brothers Emmett and Jasper after he lures Bella to an empty ballet studio and nearly kills her. The shimmery scar left by his venomous bite still remains on Bella's hand as a symbol of his unsuccessful attempt on her life. James is described as having light brown hair and being quite unremarkable and average-looking.
James is portrayed by Cam Gigandet in the Twilight film.
