Sonja is a fictional character from the Underworld series of films. She is the daughter of the Vampire Elder Viktor, introduced by flashback, in Underworld. Her character is portrayed by Jazmin Damack in Underworld and by Rhona Mitra in Underworld: Rise of the Lycans.
Biography EditSonja fell in love with the lycan slave, Lucian, despite the fact that she knew her father would disapprove. She eventually married Lucian in secret, and became pregnant with his child. This was done without Viktor's knowledge or blessing. She was executed by exposure to sunlight, as her husband was forced to watch. Viktor murdered her and her unborn child for breaking the Covenant. He viewed the child as an abomination and was acting to protect the Vampire line's purity.
Sonja bore a pendant, which was given to her by her father. After her death, Lucian took that pendent as a keepsake of his beloved wife. This pendant proved to be vitally important to the events that unfolded in Underworld: Evolution.
Her death started the war between the Vampires and Lycans that lasted for centuries after her demise.
