For the purposes of this list, a "UNIT Enemy Master story" is one in which the UNIT Enemy Master plays a part within the confines of the story, outside of flashbacks to previous stories and cliffhangers that lead into the following story. For this reason, stories such as Dalek: The Astounding Untold History of the Greatest Enemies of the Universe are not counted due to his only contribution being references to past stories. The Birthday Boy and The One are also excluded due to featuring a manifestation of the Master instead of the genuine article. Stories like Party Animals are also not included due to the Master's appearance being a cameo of little consequence to the plot of the story.
