He’s in his fifties and has dark hair and a goatee. That goatee had two blocks of white in it, coming down from his moustache. That mirrored the white hair that sat at his temples. The suit with a Nehru collar that he wore is visibly high quality. The Master is skilled with disguises, yet doesn’t get too creative with fake names. Being obvious is necessary for taunting. He’s obsessed with the idea of killing UNIT, yet won’t because he believes life is boring without his nemesis, The Doctor.
