Doctor Who Season Ten Will Feature This Fan-Favorite Character

The long-running British sci-fi adventure Doctor Who is back later this month, and it has been revealed that a key character is also returning. If you don't want to know who it is, stop reading now!

The Doctor's long-time enemy the Master will reappear in the new season, played by John Simm. "I can confirm that it's true, thanks to the power of time travel I'm back," Simm said in a statement. "It's always a pleasure to work with this great team of people and I can't wait for you all to see what the Master gets up to in the next series."

Showrunner Stephen Moffat also commented on Simm's return, and revealed that he would appear opposite Michelle Gomez, who has played the role (as the Mistress) since 2014.

"You'll have to wait a little bit longer to see exactly what the Master is up to and how he makes his return to face the Doctor," he said. "It's been a huge pleasure to have John and Michelle face to face in the same role! It's not often you get to see a solo personality clash."

Simm first played the Master in Season 3, and returned for the two-part special The End of Time in 2009. The character initially appeared in Doctor Who back in 1971, portrayed by Roger Delgado.

The upcoming season is to be the last for both Moffat and star Peter Capaldi. The pair are departing after three and six seasons in their current roles, respectively. Moffat, who serves as head writer and executive producer, will be replaced by Chris Chibnall, who previously contributed episodes such as 42 and The Hungry Earth / Cold Blood.

Capaldi's replacement, meanwhile, is currently unknown, with Ben Whishaw, Richard Ayoade, Rory Kinnear, and Rupert Grint tipped to step in.
