All you need to know about the Twilight saga characters

Jane

"This may hurt just a little." ―Jane before she attempts to torture Bella Swan.

Jane is a high-ranking member of the Volturi guard in the Twilight Saga. She is the twin sister of Alec, and together they are the Volturi's most powerful offensive weapons. Jane has the ability to inflict a mental illusion of burning pain into other people's minds, which serves greatly in providing fear and maintaining order to confrontations.

Jane was born in England around 800 A.D, the daughter of an Anglo-Saxon woman and a Frankish soldier. She was born a few minutes before her fraternal twin brother, Alec. Both Jane and Alec had strong psychic abilities that were evident even in their human state.

Aro was made aware of Jane and her brother through the thoughts of a visiting nomad. Aro had shown interest in Jane and her twin brother since they were toddlers, but decided to wait until they were old enough to turn them (the Volturi had already instated its rules about immortal children) so left them in the care of their parents. Their talents had not taken a focused shape at that point, but bad things happened to people who were unkind to the twins or their family, and good luck followed those who were friendly to them. Eventually, the superstitious locals found the twins too frightening to endure. They were accused as witches and condemned to be burned at the stake. Aro was apprised of the situation by a nomad who knew of Aro's interest in the twins. Aro hurried to the village, arriving just in time to interrupt the execution. Transformed at the age of about 12 or 13, they are the smallest and youngest in appearance, as well as the most prized members of the guard due to their incredibly powerful gifts.

Due to the pain Jane experienced during her burning at the stake and the anger she felt towards the villagers, after her transformation from human to vampire she gained the supernatural talent of inflicting the same pain on others in the form of illusion. Jane has since become one of the most prized members of the Volturi guard. About one decade after they joined the coven, Jane and her brother displayed their powers for the first time in battle and annihilated the Romanian Coven's army of over one hundred recruits. Since then, they have been known world-wide as the two most powerful vampires there ever existed and are considered the cornerstone of the Volturi's offensive abilities.

Jane's power was so frightening that she came to enjoy inflicting it on others and receiving the respect for her power. Over the centuries, she had absorbed some of Caius's sadistic enjoyment in the process.

Physical appearance

"At first I thought it was a young boy. The newcomer was as tiny as Alice, with lank, pale brown hair trimmed short. The body under the cloak - which was darker, almost black - was slim and androgynous. But the face was too pretty for a boy. The wide-eyed, full lipped face would make a Botticelli angel look like a gargoyle. Even allowing for the dull crimson irises."―Bella on seeing Jane for the first time[src]

Jane is described to be 4'8" tall and has a tiny body with lank, pale brown hair trimmed semi short and pale skin to match it. She could easily be mistaken for a preteen boy if not for her girlish face and full lips. Her face is angelically beautiful in its childlike appearance, and lovely when it is animated.

Bella describes her as having an exceptional face that would make a Botticelli angel look like a gargoyle. Her eyes are wide and her lips full, while her childlike voice is described as high and thin and usually speaks with an air of apathy or boredom, but maintains a commanding presence due to the fear she provides with her power. As with the rest of the Volturi, her eyes are dark red in color and they become darker when thirsty.

Jane and her brother Alec serve as two of the highest ranked guard members and so they wear the darkest cloaks amongst the guard.

In the Twilight films, she is portrayed as having long, blond hair that is tied in a bun.

Personality  

Jane has a very dark and sadistic personality, and she takes great pleasure in using her gift to torture others. She is easily angered when her gift is made useless, which is where her deep hatred of Bella first began. She shows strong jealousy toward Alice, as Aro is even more impressed by Alice's gift than her own. She worships Aro and is happy to be in his presence, though that adoration is mostly based on Chelsea's power.

Jane enjoys her gift, and the respect and fear that it brings her, and she never wastes an opportunity to use it on someone. But, despite her personality she seems to have a very strong as well as loving relationship with her twin brother Alec and besides Aro, Alec seems to be the person she is closest to.

It also seems that Jane has a jealous side, as she dislikes it when Aro gave Bella an extravagant gift (a diamond necklace).

Powers and abilities: pain illusion

Jane possesses a formidable gift, which has been shown to frighten even the strongest of vampires; for this reason she is feared and shown the utmost respect among both the Volturi guard and the rest of the vampire world.

Her gift is to create an illusion of burning pain: it deceives the mind of her target into believing that the body is truly being burned alive, and thus the tormenting pain is experienced throughout the whole body. A person on whom she uses her gift immediately feels excruciating pain of fire, collapses on the floor, and writhes in pain.

It is also said that Jane can control the level of pain she delivers to her victims. Due to the strength of her gift, she is able to incapacitate any vampire into a helpless target. In contrast to her brother's gift which takes some time to take effect, Jane's works very quickly. However, though her brother's gift is capable of working on multiple targets at once, Jane's can only work on one object of her focus.

Since finding Jane and Alec, the Volturi had never fought a fight where they were at a disadvantage. The only exception came during the confrontation between the Volturi and the Cullens and their witnesses. Jane, with her "burning" gift, and her brother Alec's with his "numbing" gift, are the cornerstones of the Volturi's offense. Together, they are one of the main reasons why the Volturi are referred to as invincible. Despite how powerful her gift is and the reputation it has given her and the Volturi, it is thwarted by one individual, Bella Swan. This is shown in New Moon, during their first meeting. This immunity instantly draws Jane's anger and later hatred towards Bella.
