Jane

She is the most powerful vampire in the Volturi coven - the shinest gem in Aro's treasure, along with her twin brother, Aro. No one specified her age, but she seems to be between 12 and 15 years old. She is described as very beautiful, with big bright crimson-red eyes and full lips. In the new moon book she is described as having short brown hair, but in the movie she's having a chic hair-do and dark-blonde hair. She's cruel, sadistic and selfish and the only person she seems to be nice with is her twin, Alec, and her master, Aro. She always acts like Aro's little personal pet and she seems very proud of that.
