Sydney Bristow's History
Sydney Anne Bristow (born 17 April 1975) is a highly skilled and well-established agent for the United States government. She has dealt with some significant trauma over the years: the death of her fiancé, the death of her best friend, the realization that her mother was a former KGB spy, the estrangement of many of her friends, and the constant activity and changes that she endures from being a spy on a regular basis.
Sydney is highly skilled in Krav Maga and is a hyper-polyglot, speaking English, Russian, German, Greek, Dutch, French, Italian, Spanish, Portuguese, Swedish, Romanian, Hungarian, Hebrew, Uzbek, Arabic, Urdu, Indonesian, Cantonese, Mandarin, Japanese, Korean, Hindi, Vietnamese, Czech, and Bulgarian.
After learning that the organization she had worked for seven years was actually a terrorist group, she assisted the CIA in bringing it down. She then worked for the real CIA but was attacked, kidnapped, and forced to believe she was Julia Thorne for two years before returning to the CIA, having no memory of where she had been for those two years. Feeling alienated after her return, Sydney discovered the truth about what happened to her, realizing she had gone rogue to accomplish things she couldn't do by the book and subjecting herself willingly to a mind wipe so even she wouldn't remember what she had done for two years. After taking down The Covenant, Sydney moved to APO, a real black ops division of the CIA. Her fiancé was threatened by the criminal organization Prophet 5, and she helped to fake his death. After APO took down Prophet 5, Vaughn returned and he and Sydney left APO for good.
