Sarah Kerrigan

From ORG Wiki

Sarah Kerrigan, dubbed by herself as "Queen Bitch of the Universe", was the main villain of Starcraft: Brood War. In Starcraft, she was a Ghost, but was later betrayed by Mengsk.

She is also "Queen of the Blades" and leads the Zerg.

At the end of Brood War, she was head of the strongest force left in the Koprulu sector: the entire Zerg Swarm. However, she allowed her enemies to live with the consequences of their actions, enjoying the torture their continued existence would bring them. However, she was left with a sense of foreboding at the end of BW, concerned that she felt there were 'trials yet to come'
