Female Human/Zerg Hybrid. Age: 27
Former Confederate Assassin and Co-Leader of the Sons of Korhal

Now ruler of approximately half of the Zerg Broods

Brought into the Confederate Ghost program as a child, Kerrigan was never given the chance for a normal life. The neural processing treatments that were used to dampen and pacify her latent psychic powers left her a withdrawn and introverted young girl. Forced to murder countless enemies of her Confederate masters, Kerrigan was finally exposed to a series of clandestine experiments conducted by the Confederate Government.

During a raid on a remote Terran outpost, Arcturus Mengsk discovered and rescued Kerrigan from the Confederate scientists. The Confederates had ruined both their lives, and it was a simple matter to convince the young woman to lend her formidable combat skills to his rebel strike-force: The Sons of Korhal.

After faithfully serving the Sons of Korhal for years, Kerrigan was abandoned by the power-mad Mengsk, and left for dead upon the Zerg-infested world of Tarsonis. The Zerg Overmind, sensing tremendous psychic potential and an indomitable will within Kerrigan, decided to incorporate her into the Swarm. Kerrigan's genes were spliced with those of the Zerg, transforming her into the terrible 'Queen of Blades'. Kerrigan's latent psychic powers manifested themselves rapidly, allowing her to lead the Zerg to countless victories over their enemies.
