BBC's Doctor Who has cycled through a vast cast of characters over the past half century, many of whom have been able to drop back into the action thanks to various timey-wimey shenanigans. Now, we know of one major character who will be returning to the show in Season 10. The Master will be back yet again... but not necessarily the version that many might be expecting. The most recent version of the Master is actually a woman, played by Michelle Gomez and going by "Missy." The newly-announced Master who will appear in Season 10 will be the version played by John Simm.
John Simm played the Master back in Season 3 of the Doctor Who revival, and he managed to cause a lot of trouble for the human race before the Tenth Doctor and Martha were able to defeat him. He was back in the action for Ten's last adventure in 2010, when the Time Lords returned with a vengeance. While the Master remained an enemy of the Doctor until almost the very end, he ultimately turned on the Time Lords, saved Ten's life, and was seemingly destroyed in the process.
Well, we'd later learn that he was able to regenerate and become Missy, who turned up in Season 12 to mess things up for the Doctor again, this time in his Twelfth incarnation. It seemed like the John Simm version of the Master was gone for good. The new BBC report indicates that he'll be back, presumably in all his psychotic glory, to vex Twelve.
Interestingly, he won't be the only Master on board for Doctor Who Season 10. Showrunner Steven Moffat has revealed that the John Simm version of the Master will be facing off against the Michelle Gomez version. Outside of anniversary specials that bring multiple incarnations of the Doctor into the fold, we don't often get to see two incarnations of the same person face-to-face. Master vs. Missy should make for a pretty crazy episode.
A big question now is how John Simm's Master will react to Twelve. He and Ten were on the same side against the Time Lords back in 2010, but that alliance was a very last-minute development, and there's no saying how he'll react to Twelve. It's possible that he won't have as much of a grudge as he did against Ten; it's also possible that he'll go totally bonkers on Twelve for not being Ten. Even on a show as wild as Doctor Who, the Master has been pretty nuts.
We'll have to wait and see. Doctor Who returns to the airwaves for Season 10 on Saturday, April 15 at 9 p.m. ET on BBC America.
