Jasper Hale personality type: ISTJ

Jasper Hale is the Cullen who has to work hardest at not killing you, and he knows it.

His history explains why. He was born around 1844 in what is now Texas, joined the Confederate army in 1861 and rose quickly through the ranks. In 1863 a vampire named Maria turned him at nineteen to help her claim territory around Monterrey. For about a century he trained her newborn soldiers and destroyed them when they stopped being useful. He finally left with his friends Peter and Charlotte, and later, in a diner in Philadelphia, he met Alice, who had already seen their future together.

That background is why we type him ISTJ. Introverted sensing stores experience in detail and leans on it, and Jasper is a walking archive of war. When Victoria builds her newborn army in Eclipse, he is the one who knows how newborns fight, and he teaches the Cullens and the wolves how to beat them. Extraverted thinking gives him the organized, procedural side: drills, tactics, the officer’s habits that never left.

His weak spot is the one he cannot drill away. He has the least control over his thirst of any Cullen, and on Bella’s eighteenth birthday a paper cut is enough. He lunges, Edward stops him, and the whole family leaves Forks because of that one second.

Sixes are built around loyalty and vigilance. They scan for threats because the world taught them to, and they attach to the people and systems that make them feel safe. Jasper’s systems were an army and then a family. Alice is his anchor, and in Breaking Dawn he follows her away from Forks to search for a hybrid without needing a speech about why.

His gift fits the six too. He can sense and shift the emotions of everyone around him, and in Twilight he uses it to calm a terrified Bella. A watchful type with that power spends it on lowering the alarm in the room. Jackson Rathbone’s tense, stiff-shouldered film Jasper plays the strain of it.

But: ISTP is a fair alternative, since he is a fighter who reads situations fast. Still, ISTPs improvise, and Jasper’s whole value is that he remembers. He fights by the lessons of a century of drills. ISTJ wins.
