Battle computer

The Dalek Battle Computer was a computer interface the Daleks used. The Renegade Daleks placed one on Earth in 1963. As this Battle Computer required a human interface to act as a creative intelligence, a young child was selected and conditioned to obey the Daleks. (DW: Remembrance of the Daleks) Later in their history, when they were manipulating the Fifth Axis, the Daleks experimented with older, more tactically aware human beings as Battle Computers. (BFBS: Death and the Daleks) During the Dalek-Human War, the Daleks used the brain-waves from captured prisoners on the human Space Station X-R as raw material for Dalek Battle Computers.

Appearance and Function
The Dalek Battle Computer was similar in shape to a Dalek. When it was used on Earth in 1963 during the Shoreditch Incident it was black and silver and had a young girl sitting in it. The young girl was under the Daleks' control and operated the Dalek Battle Computer. For optimum performance, her body and mind had been augmented by the Renegade Daleks. She was able to fire deadly bolts of electricity from her hands. (DW: Remembrance of the Daleks).
