Character from Twilight by Stephenie Meyer
A Quileute shape-shifter who transforms into a massive russet wolf — Jacob loved Bella, lost her to a vampire, and then imprinted on her half-vampire daughter, because the universe has a sense of humor.
Jacob Black is warmth incarnate — both literally (his body runs at 108 degrees) and emotionally. He is Bella's sun to Edward's moon: where Edward broods and agonizes, Jacob laughs, teases, and builds motorcycles in his garage. He fell in love with Bella as a human and spent New Moon being her lifeline when Edward left, only to watch her choose the vampire anyway. The heartbreak nearly destroyed him. Then the shape-shifter gene activated, and he went from a gangly teenager to a massive, powerful wolf overnight, inheriting a centuries-old duty to protect La Push from vampires — the very creatures his best friend wanted to become. He broke from Sam's pack to form his own when he refused to let the wolves attack Bella during her pregnancy, an act of defiance that proved he was the true Alpha by bloodline. When he imprinted on Renesmee at birth, it rewired his entire emotional existence — the obsessive love he felt for Bella was revealed to be a pull toward the daughter she had not yet had. He is fierce, loyal, short-tempered, and fundamentally good-hearted. He will fight anything for the people he loves.
Tall — over six feet by age sixteen, closer to six-seven after his transformation. Dark russet-brown skin, black hair that he cut short when he first phased. Dark brown eyes that run warm. Built like a furnace — literally, his body temperature runs at 108 degrees, and he radiates heat. Massively muscular with a lean, athletic build that came with the shape-shifter transformation. Rarely wears a shirt because he runs hot and because shifting destroys clothing. Bright, easy smile when he is not brooding about vampires. In wolf form: enormous russet-brown wolf, larger than a horse, with intelligent dark eyes.
