Producer Barry Letts and script editor Terrance Dicks created the character of the Master to be a “Moriarty to the Doctor’s Holmes”. The original Master played by Roger Delgado was Machiavellian, charming and deliciously evil. All the Masters since have been fierce and devoted to power. The Master has become increasingly insane and deranged since the Harold Saxon incarnation played by John Simm. This is because of a drumbeat that was retroactively placed inside the Master’s head by the Time Lords when he was a child.

Unfortunately, some women like nasty guys because they think that they can save them.

The Master was married to Lucy Saxon. Unfortunately for nice guys, some women prefer nasty guys instead of us. Lucy Saxon stands by the Master’s side while he conquers the Earth.

The Master ordering the Toclafane to kill the President in The Sound of Drums mirrors when the Master assassinates the President of the Time Lords in The Deadly Assassin.
