|Status||Alive (Possessed by SHODAN)|
|Game(s)||System Shock 2|
|Voice Actor||Esra Gaffin|
She is seen escaping the Von Braun with Tommy Suarez in an escape pod on the Command Deck.
After the Soldier defeated SHODAN, he sent a message to the escape pod informing Tommy and Rebecca that the ship was now back under their control. Tommy comments on how Rebecca has been acting strange, after which she asks if he likes her "new look"; a heavy implication that her mind and personality has now been completely overwritten by SHODAN, after she went to have surgery performed on her to heal a severe spider bite.
Rebecca is set to return in System Shock 3.
