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. More accurately, and with that wonderful Dalek sense of irony, Ka Faraq Gatri means ‘Nice guy – if you’re a biped.’ And that perhaps sums up the Doctor better than anything. He just never knows when the Daleks are kidding.
