Jasper was a major in the Confederate Army in Texas until he was turned into a vampire one dark night by Maria and two others, who were later destroyed by Jasper and Maria when they became of no use and were planning to defeat them and take over. When he became a vampire, he gained the ability to feel and manipulate people's emotions.
Jasper commanded Maria's newborn army that participated in the Southern Vampire wars. While in the army, he befriended a newborn named Peter, who Maria decided to let live. When Peter ran off with Charlotte, a newborn that they were supposed to kill, Jasper let them go. After a few years living as nomads in the Northern U.S, Peter and Charlotte came back and told Jasper about the way vampires could coexist in the North, and he left with them. A few years later he left their company. Later, he meets Alice in a diner in Philadelphia, and together, with the help of Alice's 'sight', they search for Carlisle and his family, she also tells him about the ability to survive off of animal instead of human blood. He didn't know such a thing could exist but he followed her. When he became a member of the Cullen family and while attending high school, Jasper changed his surname of Whitlock to his adoptive sister Rosalie's surname of "Hale" and poses as her twin due to their physical similarities. Out of the whole coven, Jasper has the hardest time being around humans, due to his untrained upbringing as a young vampire in an army environment. He was not taught to control or how to regulate his blood lust. Edward Cullen states that all human blood is equally tempting to Jasper, unlike the rest of the family, who can notice the variations in blood scent in different humans. He is also the newest member of the Cullen family
