Aliases of the Master

Like the Doctor, the renegade formerly known as Koschei has employed a number of aliases in the course of his career. However, while the Doctor tends to use false names on a fairly ad hoc basis in order to avoid awkward questions, the Master usually adopts them in order to further whatever scheme he is currently embarked upon.
