Making Of Sarah Kerrigan Sculpture

In an interview, Kerrigan's voice actor, the author and voice artist Glynnis Talken Campbell, described Kerrigan's change in personality during her infestation as "going from good girl to bad girl", and has said it was more of a change in personality than voice when providing her voice work. Kerrigan's voice also consisted of many grunts, growls and screams, and her unique infested voice was provided by doubling up Talken Campbell's voice. She has also claimed that, were she to pen a StarCraft film or novel, she would rather have Kerrigan's relationship with Jim Raynor—the series' primary male protagonist—portrayed as one of admiration, sacrifice and "them saving each other's butts" than actual romance due to StarCraft's action-oriented nature. Whilst Talken Campbell had confirmed that she will return to voice the character in StarCraft II, and had voiced the character in several promotional trailers, it was later reported that a new voice actor had been hired for Kerrigan and that Talken Campbell was no longer involved with the project. Tricia Helfer is now the new voice actor for Kerrigan in StarCraft II: Wings of Liberty, as well as its expansion sets Heart of the Swarm and Legacy of the Void.
Personality
Having been conscripted into the Confederate ghost program as a child due to her psychic potential, Kerrigan is described in the manual for StarCraft as never being given the chance for a normal life. Her rigorous training and the use of neural implants to control her mental abilities leave her a withdrawn and introverted woman. Despite this, Kerrigan exhibits qualities of courage and daring, and is an effective tactician. She is also described as a moral character, exemplified in her opposition to Arcturus Mengsk using the Zerg against the Confederacy. However, after her transformation by the Zerg, Kerrigan is freed from her inhibitions—as well as her neural conditioning—and indulges her darker traits. Her attitude is described by the publication WomenGamers.Com as "spiteful, conniving, mocking, double-crossing flamboyant", which when combined with her natural intelligence makes her extremely calculating and manipulative. Kerrigan has also become far more physically aggressive, relishing in close quarters combat so much that one point in the novel Queen of Blades she begins absent-mindedly licking the blood of her victims from her fingers.
