Time is up for the clock-defying Doctor but Peter Capaldi’s got one epic final adventure in store that will see him unite with companion Bill Potts one last time
PETER Capaldi's time as The Doctor is almost up but a new picture for the upcoming Christmas special shows he still has one last dramatic adventure.
The twelfth doctor will have to join forces with the first Time Lord after a mysterious evil force throws space and time into chaos.
Peter Capaldi's Doctor stands centre next to David Bradley's incarnation of the very first Doctor, originally portrayed by William Hartnell between 1963 to 1966.
A golden glow covering the Doctor's hand hints at his inevtiable regeneration, which is expected to take place at the end of this Christmas special.
Equally surprising is the inclusion of companion Bill Potts and while Pearl Mackie's role had already been confirmed, fans were expecting her to have a more fluid appearance.
In the recent finale episode, Bill had been stuck in the form of a deadly Cyberman but was rescued by her doomed fate and turned into a sentient oil puddle that can travel the universe.
The BBC has also released an official synopsis for the Christmas special which has been titled, Twice Upon A Time.
It reads: "Two Doctors stranded in an Arctic snowscape, refusing to face regeneration. Enchanted glass people, stealing victims from frozen time. And a World War One captain destined to die on the battlefield, but taken from the trenches to play his part in the Doctor's story."
The episode promises to be "an uplifting new tale about the power of hope in humanity's darkest hours."
Taking a more mysterious route, the synopsis adds: "As the Doctor must face his past to decide his future, his journey is only just beginning."
