Russ Bain

 voiced several characters in the Big Finish Doctor Who main range audio stories.

Notably, in And You Will Obey Me, he briefly played after the Master took over the body of his character, Michael Masterson, in circumstances reminiscent of the Master's theft of Tremas's body in The Keeper of Traken. However, the Master then decayed back into a duplicate of the Geoffrey Beevers within the same scene. Insofar as stolen bodies such as Anthony Ainley and Eric Roberts should be considered "incarnations" of the Master, this makes "Bain's Master" the shortest-lived version of the character in-universe.
