Twelfth Doctor

The Twelfth Doctor is the titular protagonist in Series 8-10 of the revived series of Doctor Who and a minor character in the spin-off series, Class. 
He was portrayed by Peter Capaldi, and voiced by Jacob Dudman in Big Finish's The Doctor Chronicles. 
== History ==
It was not until his first battle with Missy, a female incarnation of the Master, that the Doctor resolved his morality crisis, realising he was simply "an idiot with a box and screwdriver" who went around helping others. Following this, the Doctor began to show his lighter side more clearly and forged a closer bond with Clara. The Doctor continued his travels with Clara, haunted by the reemergence of the Hybrid prophecy he had heard of in his childhood. After Clara was killed due to a trap set for him, in Face the Raven, the Doctor was trapped in his own confession dial, where he spent four billion years fleeing the Veil. In the Series 9 finale Hell Bent, the Doctor broke his own moral codes and unleashed his wrath upon the Time Lords in an ultimately futile attempt to save Clara, and after realising he was becoming the metaphorical Hybrid, accepted losing his memories of her as a price for his reckless actions.
In the 2015 Christmas special The Husbands of River Song, the Doctor reencountered River Song, who for the majority of the episode, was unaware of his true identity until he said "Hello Sweetie" to her. After defeating the robotic body of King Hydroflax, the Doctor and River spent a 24-year long night at the Singing Towers of Darillium. In the 2016 Christmas special The Return of Doctor Mysterio, the Doctor, with the help of River's former assistant Nardole and a man named Grant (whom as a child, met the Doctor and accidentally ate a gem, which granted his wish to be a superhero), defeated brain-like aliens called The Shoal of Winter Harmony.
In Series 10, the Doctor and Nardole guarded Missy, going "cold turkey" from evil in the Vault, for decades under St Luke's University while the Doctor acted as a tutor. The Doctor noticed a student, a woman known as Bill Potts who he took on as a companion after discovering Heather, the woman Bill was interested in, had become a sentient oil creature. Initially sneaking away to travel with Bill, the Doctor was joined by Nardole in Oxygen, where being exposed to the vacuum of space left him blind. Shortly after this, the Doctor became aware of The Monks, but when his unwillingness to talk about his blindness left him in a dire situation, his sight was restored at the cost of Earth's freedom. Eventually, the Doctor, Bill and Nardole, with advice from Missy, were able to defeat the Monks. After this, the Doctor divided his time between adventuring with Bill and Nardole, and supporting Missy's redemption.
Eventually, when it seemed that she had reached a turning point, the Doctor tested Missy's evolving goodness by rescuing a ship from a black hole. Soon, the situation went off the rails, and the Doctor discovered that the ship was a Mondasian Colony Ship. Bill was converted into a Cyberman, and events were being manipulated by Missy's predecessor (the Harold Saxon incarnation) to create a new breed of Cybermen. Left to defend the remaining colonists, the Doctor fought off the Cybermen, and was mortally wounded. Bill was restored by Heather and the two put the Doctor in his TARDIS, going onto travel together, whilst Nardole remained behind to protect the others from Cybermen. In the 2017 Christmas special Twice Upon A Time, the Doctor, refusing to regenerate due to weariness, encountered his first incarnation and met a glass avatar of Bill. Convinced to carry on living, the Doctor bade farewell to the avatars of Bill and Nardole and regained his memories of Clara. The Doctor returned to the TARDIS to regenerate, giving some final advice to his successor.
==Personality==
This version of the Doctor became a less amiable character, as he no longer needed to cover the pain of the extinction of the Time Lords, with a withdrawn attitude who questioned his own goodness. He often dispensed with niceties in a tense situation, becoming cold and calculative when needed. However, despite his ruthless exterior, the Doctor was actually deeply caring and empathetic, always striving to help others for the sake of being kind. Unlike other incarnations who grew into their appearances, this version of the Doctor seems fairly self-conscious, and saw the role of "The Doctor" as an ideal to strive towards. 
He still held the pain of the War Doctor deep down. This resulted in him having a strong rage and disgust for Bonnie, whom started a zygon rebellion; because she thought it was unfair zygons had to live in hiding just to live on Earth. The Doctor pointed out that he would force Operation Double to stay in place, no matter what he had to do; calling her a petty child who just perpetuated cruelty.

==Trivia==
*His predecessor's time in Trenzalore lead the Twelfth Doctor to see lying as a necessary life skill; having learned to technically not lie.
*When he put Operation Double back in place, the Doctor revealed he just keeps wiping the memories of both Kate and whatever Zygon is rebelling until they finally relent and back off.
*His aged appearance is disliked by the First and Eleventh Doctor; given that regeneration should make them younger.
**While he still had the Eleventh's persona lingering, the Doctor wondered "who frowned me this face"
**Though the Twelfth is physically younger than the First, as his regeneration was caused by Cyberman lasers and not old age.
*The Comic stort "The Four Doctors" show he does not want to run into the Eleventh the most of his past incarnations; explaining he was a future Doctor would risk paradoxes in getting new regenerations on Trenzalore.
