What Monsters & Characters Could Show Up In Doctor Who Season 15?
New & Familiar Faces Could Appear
Doctor Whoseason 14 endedwith the Fifteenth Doctor facing off against Sutekh, a villain who first appeared in episodes featuring the Fourth Doctor back in 1975.This follows a trend of the show bringing back characters from its far-off past, using threats like the Toymaker in the 60th anniversary specials in order to add a level of tighter consistency to the series. However, Gatwa’s statement indicates there will be plenty of new faces to expect in season 15, meaning fresh, original characters might be the priority for the show’s forthcoming episodes.
While it’s unclear what new allies and enemies could be joiningDoctor Who’s cast,one confirmation is Varada Sethu, who will be portraying a new companion in the next season.As for other possible newcomers, they could be revealed through a known source like UNIT, assisting the Doctor in whatever situation he’s in during a particular episode. As for potential monsters, these could include the characters hinted at by the Toymaker before his demise, adding a new layer to an old character in the process as well.
Some elements of season 15’s new characters and monsters will likely show up in the next Christmas special, “Joy to the World,” which acts as the bridge from season 14. AlthoughDoctor Whohas plenty of new appearances that will happen in season 15,there’s also plenty that remains unseen, likely to be unpredictable until the episodes finally arrive.With so many directions the next season could go, it’s up in the air just how many new faces are going to show up when the season finally begins.
