Overmind. In an interview Glynnis Talken Campbell, Kerrigan's voice actress from Starcraft and StarCraft: Brood War, 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 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. While Campbell expressed interest in returning to voice the character in StarCraft II, and even voiced Kerrigan in the trailer for the game, she confirmed in February 2009 that she would not be reprising the role. Campbell stated that her work in the trailer was considered an audition of sorts and that Blizzard had decided to go in a different direction.

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 (though Heart of the Swarm implies that at least part of her villainy was due to the influence of a fallen Xel'naga named Amon). Her attitude, combined with her natural intelligence, makes her extremely calculating and manipulative. A hint of her former moral sensitivity is to be noted when towards the end of the Zerg campaign of Brood War, she states how she feels weary of
