Aliases of the Master
Like the Doctor, the renegade Time Lord known as the Master (who, according to some sources, was once known as Koschei) used many aliases in the course of his career. However, while the Doctor used false names on a fairly ad hoc basis to avoid awkward questions, the Master usually adopted them in order to further whatever scheme he was currently embarked upon.
Variations on 'the Master'
The Master
The Master effectively discarded his former name. He and the Doctor referred to each other by their titles as a matter of course. While earlier in his life he was heard saying that he was "known as" the Master, by the time of his final confrontation with the Doctor's tenth incarnation, he considered "The Master" his name (DW: The End of Time).
UNIT era aliases
During a period when the Master came into frequent and regular contact with Earth's United Nations Intelligence Taskforce and the Doctor's third incarnation, he used aliases, many of which were plays of the name "Master".
