Twelfth Doctor
The Twelfth Doctor was an incarnation of the Doctor that initially travelled with Clara Oswald. He emerged from the Eleventh Doctor's explosive regeneration on Trenzalore, and was the product of what his predecessor called "regeneration number thirteen".
Biography
Shortly after regenerating, this Doctor voiced his surprise at having new kidneys, and his inability to fly the TARDIS, much to Clara’s obvious dismay. (TV: The Time of the Doctor)
The TARDIS "was crashing everywhere", getting swallowed by a T-Rex, which got brought along to the Thames in the Victorian era by accident. Upon being spat out, the Doctor exited the TARDIS, only to be in a further state of confusion that worried his old friends, the Paternoster Gang. Though put to bed to stabilise, the Doctor soon left when the T-Rex was burned to ashes; he took off to follow a suspicious person not alarmed by the event. Coming accross a mirror later, the Doctor was puzzled by his new face, knowing he had seen it before, but couldn't remember yet. Meeting back up with Clara, the Doctor infiltrated a suspicious restaurant, where he learned Clockwork Droids had been harvesting humans to repair themselves. Their leader, the Half-Face Man, sought to reach the Promised Land, but fell out of his escape pod, either jumping or having been pushed by the Doctor.
He briefly left Clara behind, using the time to redecorate the console room. Attempting to return her to 25 December 2013, the Doctor ended up in Glasgow by mistake. However, they decided to go out for a meal after the Eleventh Doctor called Clara and encouraged her to help the new Doctor. (TV: Deep Breath)
Undated Events
At some point in his travels, he joined his previous selves in helping place Gallifrey in a pocket universe at the end of the Last Great Time War. (TV: The Day of the Doctor)
Behind the scenes
- Like the War and Ninth Doctors, the Twelfth Doctor unusually debuted on television before his regeneration from his predecessor was screened.
- His first words — "Kidneys! I've got new kidneys!" — keep to the modern tradition of new Doctors commenting on their bodies. Previously, the Tenth Doctor commented on his "new teeth", (TV: The Parting of the Ways) and the Eleventh on his legs. (TV: The End of Time)
