Twelfth Doctor

The Twelfth Doctor was an incarnation of the Doctor who travelled with Clara Oswald. He emerged from the Eleventh Doctor's explosive regeneration on Trenzalore, being the product of what his predecessor called "regeneration number thirteen" as well as being the first incarnation of the Doctor's second regeneration cycle.

A chaotic beginning
After fighting in the Siege of Trenzalore for 900 years, (PROSE: Tales of Trenzalore: The Eleventh Doctor's Last Stand) the Eleventh Doctor, facing extermination by the Daleks in his old age, was ready to accept that he had reached the end of his life. Clara Oswald appealed to the Time Lords to intervene, and he was granted a new regenerative cycle. After using his regenerative energy to destroy the attacking Daleks and their mother ship, the Eleventh Doctor returned to the TARDIS to complete his regeneration.

Suddenly changing in a flash before Clara's eyes, this new Twelfth Doctor first expressed surprise at sensing his new kidneys, stating, "I don't like the colour!" The TARDIS then began shaking violently, and the Doctor implied to have forgotten how to pilot his ship. (TV: The Time of the Doctor) Crashing in pre-historic Earth, the TARDIS was chased and subsequently swallowed by a female Tyrannosaur; when the Doctor brought the TARDIS to 1890s London, this dinosaur was accidentally brought along with it. (TV: Deep Breath)

In London, the Doctor was reunited with the Paternoster Gang, and witnessed the apparent spontaneous combustion of the dinosaur. Though still suffering from partial amnesia and occasional delirium as after-effects of the regeneration, he learned Clockwork Droids had been harvesting humans to repair themselves. Their leader, the Half-Face Man, sought to reach the Promised Land. The Doctor confronted the Half-Face Man, and warned him that he would do whatever necessary to protect the innocent humans that the droid was targeting.

Trying to speak on peaceful terms, the Doctor snapped the droid out of his illusion of the "Promised Land" by revealing the true state of his existence. Having switched out spare parts so many times, the Half-Face Man had truly no traces left of his original self. Knowing he would not go to a promised land or be truly alive, the Half-Face Man's logic dictated him to self-terminate, but he said it was against his basic programming, struggling against the Doctor. The Doctor replied that murder was against his "programming". Both agreeing that one of them was lying, the Half-Face Man ended falling out of his escape pod, to his death.

The Doctor, having completely regained his memory and senses, briefly left Clara behind to redecorate the console room and settle on a new outfit. Attempting to return her to 25 December 2013, the Doctor ended up in Glasgow by mistake. However, they decided to go out for coffee after the Eleventh Doctor called Clara and encouraged her to help the new Doctor. (TV: Deep Breath)

Am I a good man?
Leaving Clara behind in Glasgow to get coffee, the Doctor got distracted, and ended up saving a Dalek resistance fighter named Journey Blue, leaving her brother Kai behind in the explosion. Meeting a Dalek that had developed a fault and turn good, the Doctor returned for Clara, three weeks later from Clara's perspective, and the duo joined a team to shrink into the Dalek and heal the Dalek. However, fixing the Dalek — whom the Doctor nicknamed "Rusty" — caused it's destructive nature to reboot, causing the deaths of many of the Aristotle crew. Attempting to convince Rusty to remember how it changed, the Doctor mind linked with Rusty, causing the Dalek to see the Doctor's hatred of the Daleks and destroy the Daleks that had responded to Rusty's distress beacon. Leaving to ensure the Daleks did not futher attack the Aristotle, Rusty commented that Doctor would have made a good Dalek before both of them left. (TV: Into the Dalek)

Early exploits
Spending some time on his own, the Doctor became alerted to a creature that disguised itself as a motorway to consume planets into other dimensions. Summoning Clara to assist him, the Doctor was surprised when the creature disappeared, unaware that Clara had tricked the creature into consuming itself. (COMIC: Road Rage)

The Doctor and Clara used a slime explosive to foil the Sibro's attempt the weaponize an Chanlanian clock tower. (COMIC: Chime Time)

Undated adventures

 * The Twelfth Doctor 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)
 * The Twelfth Doctor, along with his other incarnations, attended Alistair Gordon Lethbridge-Stewart's funeral. (PROSE: The Gift)

Personality
A sarcastic man, (COMIC: Chime Time) the Twelfth Doctor was dark and manipulative, willing to place his companions in danger if it meant appeasing his curiosity. Despite this, he would fight to protect those in his care, and would react with devastation if harm befell them. Such was his reaction to the death of a female Tyrannosaurus rex that had been inadvertently dragged through time by the TARDIS. (TV: Deep Breath)

The Twelfth Doctor showed even less restraint than his predecessor, and would get frank and physical with his enemies. (TV: Deep Breath) However, he often skirted a jagged line between right and wrong values due to a conflicted sense of morality and the struggle with his inner darkness. He sometimes voiced preconceptions about his enemies or human nature, but might find them maligned and questioned his own judgement afterward. (TV: Deep Breath, Into the Dalek)

Following his long stalemate with the Daleks on Trenzalore, this Doctor's hatred toward the Dalek species was rigid. He seemed conditioned to believe Daleks could not change and was close-minded as he dealt with their presence. After considering the right course of action to perform on a malfunctioning Dalek, he decided to fix it, reasoning that it was impossible for it to be good, despite a universe that was full of unexplored possibilities. This choice horrified those in his presence, notably Clara, who became angered to the point of slapping him. (TV: Into the Dalek)

Though he retained a respect for humanity, the Twelfth Doctor would insult them for being slow minded and violent, dubbing Earth the "planet of the pudding-brains". He also claimed to dislike karaoke and mime. (TV: Deep Breath) He also disliked soldiers because of their hidebound nature, to the point where he found them painful to take on as companions even if they still had good virtues under their military-mindedness. (TV: Into the Dalek)

Though this Doctor stated that murder was against his moral code, he and the Half-Face Man agreed that one of them was lying about their basic programming. Indeed, the Doctor did show some initial reluctance in going forth with killing the Half-Face Man himself, offering him a drink of alcohol and trying to persuade the Clockwork Droid to self-destruct of his own free will. (TV: Deep Breath) He showed no reluctance in letting others die if it meant saving the majority, at least regarding soldiers, saving Journey Blue from her exploding ship while showing no remorse for her brother's resultant death, and manipulating the imminent death of Ross to his own advantage. (TV: Into the Dalek) However, the Twelfth Doctor, like many of his past incarnations, was heavily inclined to err toward a greater good and put the survival of the many above a single individual. Through this attitude, he acted like a pragmatist that would not hesitate to abandon someone whose fate was already sealed. (TV: Into the Dalek)

Habits and quirks
Like his seventh incarnation, the Twelfth Doctor spoke with a Scottish accent, which he took as an entitlement to complain about things.

After working out the important questions in his head, he waited for others to come to the same conclusion, becoming increasingly annoyed with each wrong question they proposed.

Much like his predecessor, the Twelfth Doctor also used hand gestures to extenuate a point, but applied more dedication to his movements, standing firm, while speaking with conviction. (TV: Deep Breath)

Skills
Highly observant, the Doctor was able to point out the Half-Face Man as non-human from his lack of interest in a burnt dinosaur corpse, and later noticed that he and Clara were trapped in a room full of Clockwork Droids due to only them breathing.

The twelfth incarnation retained his predecessor's ability to converse with other species, such as dinosaurs.

Strong and durable, the Doctor was able to support his own weight single-handedly, wrestle the Half-Face Man into a corner, fell out of a high tree branch and shook off the fall quickly, and dove off a bridge into the Thames to swim across the river without being hampered, though the latter two events can be linked to him still being within the early hours of his regeneration. (TV: Deep Breath)

Appearance
While a good many of his predecessors, especially the Eleventh, began their lives looking young, (TV: The Parting of the Ways, The End of Time) the Twelfth Doctor started out appearing very much older. He had short grey hair, a hooked nose and sharp silverly blue eyes, with big ears. (TV: The Time of the Doctor) He was of a light build. (COMIC: Chime Time) Clara was confused at the Twelfth's older appearance, saying to Vastra that "he [didn't] look renewed." Even the Doctor was confused about his aged appearance, asking himself, "Who frowned me in this face?" (TV: Deep Breath)

Most changed were his eyebrows, which went from "delicate" (TV: The Time of the Doctor) to extremely thick and furrowed. (TV: The Day of the Doctor) Startled by the change, the Doctor described them as "attack eyebrows" which could "take bottle tops off". (TV: Deep Breath)

Clothing
Immediately following regeneration, he initially wore the Eleventh Doctor's attire, and then a coat that he "bought" from a tramp.

After having a chance to return to the TARDIS, though, the Doctor chose a new outfit for himself. He donned a navy blue cardigan with a white collared shirt with no tie, matching blue trousers that now covered his ankles instead of being too short, and black brogue boots. Over the top, he sported a thigh-length, dark blue jacket with red lining, often wearing it with the top button done. On his left hand ring finger, he had a pair of gold rings, a normal gold band and a second ring with an emerald gemstone that rested atop the first band. (TV: Deep Breath)

The Doctor would wear variations of his attire, switching out his cardigan for a buttoned waistcoat of the same colour. (TV: Into the Dalek)

Behind the scenes

 * Like the War and Ninth Doctors, the Twelfth Doctor 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 Ninth Doctor commented on his ears, (TV: Rose) 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)
 * His costume was revealed in DWM 470 and online.
 * He starred in The Daft Dimension, a comic strip published in Doctor Who Magazine.
 * Peter Capaldi wanted to wear his wedding ring as part of his Doctor's attire, and requested a prop to disguise it. He was given an emerald ring with a gemstone that fits over the top of his original band. The First Doctor also wore a gemstone ring, and as such the Twelfth Doctor is the first incarnation since then seen to sport one. He is also the first incarnation since the Third Doctor to wear an ordinary ring.
