Ten-Six-Six

Cyber-Unit Ten Six Six was a Cyberman used by the Cyber-Leader to (along with Unit Ten Six Five) investigate the Sphere Chamber in Torchwood One. On his way to the Sphere Chamber with Ten Six Five they opened a visual link to the Cyber-Leader. Round a corridor they came across Dalek Thay. Thay demands that the Cybermen identify themselves. Instead of answering he demands that Thay identifies. Thay demands again and so does Units Ten Six Five and Six. Thay screams 'Identify!' and the Cybermen reply that the answer is 'illogical'. Thay replies 'Daleks do not take orders.' The Cybermen finally identifies the creature as a Dalek and a few seconds later the Daleks identify the Cybermen. Unit Ten Six Five proposes an alliance and Thay denies killing both units. (TV: Doomsday)
