- "We'd play hide and seek sometimes. No one can hide like me. But no one can seek like James. Some games lasted for months, but we'd always get hungry for each other, so I'd let him find me... We never could get sick of each other. We would've had forever to try."
James was changed by a French vampire at the age of 25 around 1805. He was a naturally skilled tracker because of his nomadic human life with his parents, his father raised him to track and trap. After his parents were killed by the Iroquois, he survived on his own and over time gained a measure of fame during his late teens and early twenties as the best tracker on the frontier.
After he'd been changed, he hunted down his creator and killed him. In the next hundred years, he used his tracking gift to find his prey and killed for entertainment over nutritional needs. Eventually, he grew tired of how easy it was to track humans - it could take some time, but he always caught up, and began to redirect his game plans to targeting vampires, sometimes even a coven. He enjoyed the danger and the rage it may cause to the other members that would make them chase him.
His biggest challenge came when he hunted Victoria, who always escaped.
She and her older sister were scullery maids to an abusive master. They escaped when Victoria was 12, but the two landed the same jobs with an equally abusive master. These experiences made Victoria learn to avoid her masters and eventually survive on her own when her sister went missing one night and never came back.
Her sister came back a few years later as a vampire, and changed her. She was introduced to a coven of female vampires and they lived happy lives before the Volturi claimed that they had "attracted" too much notice from humans and killed their leader, Hilda, and taking another member, Heidi, into their coven. Victoria sensed the danger and rushed the rest of her coven to escape, but only she survived.
In England, James came across Victoria's scent and decided to hunt her. While tracking Victoria, he found himself unable to even get near her as she always managed to escape even after years of hunting. Eventually, he became interested with her escaping ability and wanted to learn more about her.
When she let him catch up with her, there was immediate attraction, though James wanted Victoria. Victoria was attracted to his gift, honesty in his intentions and confidence. Eventually, she fell in love with him, though their lifestyle constantly put her life at risk.
He took interest in her ability to escape and survive, and wanted to use it to his advantage. He was not quite as devoted to their relationship as Victoria was. He never quite forgave Victoria for making him doubt when he was hunting Alice Cullen.
Victoria and James, with their fellow nomad Laurent, find the Cullens playing baseball. While asking the Cullens if they can play too, James picks up Bella's scent and decides to track her and kill her for sport. A hunt begins which ultimately ends with James death, although, James managed to find Bella using his gift as an excellent hunter, with Victoria helping him by sending him information about Bella. Edward stops James from further harming Bella and his brothers kill him with help of Alice. James was ripped apart and his body parts were burned to ashes. This upsets Victoria and her revenge for his murder is the main plots of Eclipse.
In New Moon, Victoria is only mentioned in the book and appears a few times in the film. She tries to kill Bella to make Edward go through the pain that she felt when James died. However, she is constantly thwarted by the Quileute wolves.
In Eclipse, Victoria plays a major role and is the main antagonist. She gathers a newborn army to destroy Bella and the Cullen family. It leads up to a fight between the Cullens with the shape-shifters against the army, and Bella, Edward and Seth against Victoria and Riley, a newborn whom she claims to love. Edward tells her that James was with her only because her talent, to know where a safe place is. It is also said that Bella hears Victoria's voice in Eclipse for the first time. The Cullens and the werewolves manage to kill the Seattle newborn army, Riley, and Victoria.
