Karfelon android
From Tardis Wiki, the free Doctor Who reference
Karfelon androids were androids which policed the people of the planet Karfel. They were identical, all having blonde hair and cobalt blue skin. Physically imposing and strong though rather incongruously featuring a high-pitched voice, some androids were armed with a beam weapon in place of a hand. The androids could only walk in a straight line halting before altering direction such as when taking corridor corners and were therefore slow to navigate around obstacles. Their main weakness was being confused by mirrors therefore all reflective surfaces in the Citadel were banned. (TV: Timelash)
