Screamer (Screamers!)

The Screamers  were seen as the breakthrough of a genius by their creator, Professor Piritus Eglon. His genetic experiments merged the DNA cells of human and Argonian to produce a new life form. This took the form of a head on an arm and resulted in the death of their creator. Their scream could drive a human unconscious. From the Argonian genetic material, they could survive in almost any state without food, water or air. Capable of intelligent thought, the first Screamer was able to operate Eglon's cloning computer to duplicate itself. Regarding them as too dangerous to be allowed to roam free, the Eleventh Doctor requested that Argonian authorities seal the Screamers in the castle that was formerly Eglon's prison.
