Sarah Louise Kerrigan, the self-styled Queen of Blades, is a fictional character in Blizzard Entertainment's StarCraft franchise. The character was created by Chris Metzen and James Phinney, and her original appearance was designed by Metzen. Sarah Kerrigan is voiced by Glynnis Talken Campbell in StarCraft and Brood War, Tricia Helfer in StarCraft II: Wings of Liberty, Heart of the Swarm and Legacy of the Void, and Vanessa Marshall in Heroes of the Storm. Kerrigan first appears in StarCraft as a twenty-six-year-old Terran Ghost, a psychic trained both physically and mentally as an expert espionage agent and assassin. Initially the second-in-command of Sons of Korhal, a revolutionary movement against the oppressive Confederacy of Man, she is captured by the insectoid Zerg and "infested" (in-universe term for genetic mutation), turning her into a human/Zerg hybrid completely under the control of the Zerg Overmind. She becomes one of the Zerg's most powerful agents, but during the Brood Wars, she replaces the Overmind following its destruction at the end of the great war, and gains control of the Zerg to seek dominance over the galaxy. Kerrigan's life before her infestation is further explored in the Starcraft novels Uprising and Liberty's Crusade, while Queen of Blades elaborates on her infested character. As one of the major characters of the series, Kerrigan has been critically praised for her believability and character depth. Kerrigan is frequently featured in "top" character lists of video game female characters and villains. Character design The character of Kerrigan was created by Blizzard Entertainment's Chris Metzen and James Phinney, with her physical appearance designed by Metzen. Kerrigan was not originally intended to be a major character, and was only meant to appear on a single level. Initially based around the character Tanya Adams in the Command & Conquer: Red Alert series, Kerrigan was named after Nancy Kerrigan, who at the time was involved in a feud with Tonya Harding. However, Kerrigan's character grew on the developers, who decided to give a far greater role to the throw-away character. Kerrigan's self-proclaimed title is the "Queen of Blades", which is gradually introduced to other characters to the point where it is synonymous with her. Chris Metzen has explained that it was meant to be an honorific title; a blade is a weapon designed to rip enemies to pieces, making the title fitting for Kerrigan, who evolved to be the greatest agent of the Zerg
