Physical appearance
Jacob has russet skin, black hair and dark eyes. In Twilight, he is described as a lanky 6′2″ fifteen-year-old with a long black ponytail. By Eclipse, Jacob stands at 6′7″ and has a toned and muscular build. In New Moon, after discovering that he is a werewolf, he cuts off his long hair. He later grows it out in Eclipse because he thinks Bella prefers it long. This makes his fur as a wolf shaggier and longer than that of his brothers. He is said to be quite handsome, often being described by Bella as beautiful. He tends to wear only cut-off style jeans and shorts, since clothes are often ruined during his transformations into a wolf. As a wolf, Jacob’s fur is a russet color.
Bella describes Jacob as a “happy person” who extends this happiness to the people around him. As Jacob’s character emerges in New Moon, he is shown to be cheery, passionate, adventurous, but quick in temper. Jacob is also able to phase at will into a giant wolf. His body temperature is warmer than a human’s, reaching about 108.9 °F (42.7 °C), which allows him to withstand very cold weather. His body also heals quickly, he can communicate with his werewolf pack telepathically when in wolf form, and he is physically stronger and faster. Werewolves do not age if they regularly turn into their wolf form, with Jacob’s body physically grown to the equivalent of a 25-year-old. Once they begin phasing, a werewolf may “imprint”—a method of finding one’s soul-mate—on someone, and will act as a close family member if the imprintee is not yet old enough to be their lover. Jacob imprints on Edward and Bella’s daughter Renesmee in Breaking Dawn, and acts as an older brother figure to her
