The Daleks of Skaro, of course, know him as the Ka Faraq Gatri. Traditionally this is translated as ‘Bringer Of Darkness’, though Professor Lyttle has established beyond reasonable doubt that this translation was, typically, the work of the Doctor himself.

He just never knows when the Daleks are kidding.
