Kate Yates

Kate Yates was human. She was hit by a car in 2007 and her Dalek Factor was later activated, giving her enhanced strength and intelligence and blond hair. She developed a hatred of humans, and made her own Dalek weapons. Her first victim was a burglar, whom she later claimed to have exterminated. She did not seem to remember being human, and denied her humanity when an armed robber broke into her house. The thief called her a traitor to her race before she shot him with an improvised Dalek gun.

She also could control humans: She brainwashed her sister and her friends to serve her new Dalek empire. She even decided to wipe her own memory of humanity as she believed it interfered with her potential. Despite outward appearances, her mindset made a force of battle Daleks recognise her as one of them. (PROSE: I am a Dalek)
