The Cyber Co-ordinator was an immobile cybernetic machine and acted as a leader of the Cybermen, similar to that of a Cyber-Planner. It was said to be ten thousand years old when the Seventh Doctor met it in 2006. As an experiment to gain mobility, it had itself implanted into the recently converted Cyberman, Bono Brooks, and became the first instance of a Cyber-Controller. (PROSE: Iceberg)
