Black Dalek (A Hero like the Doctor)

A Black Dalek once chased the Twelfth Doctor through a metallic corridor and attempted to exterminate him. However, the Doctor used his sonic screwdriver to close sliding doors just as the Black Dalek was crossing a gateway. The two heavy metal doors thus held the confused Dalek in place like a vice, while the Doctor made his escape. (WC: A Hero like the Doctor)
