Twelfth Doctor (Mozenrath)

The Twelth Doctor was the twelfth incarnation of the Time Lord known as Loki the Other of the House of Lungbarrow. Although a eccentric, light-hearted character, the twelfth incarnation's jolly persona was partnered with that of a dark, mysterious and cunning manipulator, which would eventually take the form of the Valeyard.

Personality
The Doctor's twelfth incarnation was most definitely not human-like in nature, and he stood apart from others, even his own people. Despite being known for his dark personality, the twelfth incarnation was known for his use of words to resolve problems as opposed to violence.

A mysterious character, the twelfth Doctor appeared as both a selfish anti-hero and a noble figure, defending truth and the innocent. He was by turns casually disdainful yet formally gracious. During this phase in his life, the Doctor was irascible, a brilliant but often short-tempered scientist. He refused to stand to the Nazis and, to add insult to the injury, tripped the Nazi commander so that the Doctor looked supirior to him. This Doctor would get particularly snappish with those who doubted the TARDIS could actually travel through space and time.

Paradoxically, he had a deep streak of ruthlessness, particularly when dealing with an adversary. He had no problem hitting, or even killing, when a life was threatened. Although generally peace-loving and kind-hearted, as per most of his other incarnations, the Twelfth Doctor could also react with sudden violence when necessary. He was also not against taking a life in extreme circumstance, but would scolded others for unnecessary killing. He told Adolf Hitler that the result of Holocoast was his own fault and took no action to help the begging Hitler and proceeded to leave him to his fate. He was also easily agitated when people or objects did not do as he wished them to, and would resort to physical confrontation and somewhat reckless behaviour to achieve his goals. However, he would become almost threatening when his companions suggest they use weapons against less threatening enemies, claiming it wasn't how he solved problems.

This incarnation was unafraid to pitch in with his physical skills, often bringing his mastery of Venusian aikido into play when the situation called for it.

Much like his predecessors, his keen mind was still his primary asset, and this was an incarnation who particularly loved to create and play with gadgets of all sorts. In fact, in what little free time he had, he would spend time create new gizmos and gadgets, such as making the Sonic screwdriver Mark VIII for River Song.

His mind would often leap ahead of anyone, including himself. He delighted in keeping both friends and foes alike off guard with oddball humour and curious pranks, as in his second and fourth incarnations. The twelfth Doctor often played the fool to lull his opponents into underestimating him.

Despite his charm and offbeat humour, the twelfth incarnation was arguably more aloof and sombre than his previous incarnations. He could become intensely brooding, serious and even callous, and would keenly scrutinise his surroundings even when playing the fool. He could also be furious with those he saw as unintelligent, frivolous, misguided or evil. When taking charge, he could be considered authoritative to the point of egocentricity, but as it is, he was usually the only one capable of solving the situations he found himself in.

This "darker" side would come to define him, as the twelfth incarnation became a master manipulator who saw the battle between good and evil as a game of chess and everyone around him as pawns, to be manipulated in the pursuit of stopping evil. Frequently, he would only see the "bigger picture" rather than the world before him. Often, he would not sufficiently explain this bigger picture to his companions.

The twelfth Doctor regularly provided his name as a threat, which only rarely worked, despite his apparent expectations. This was mostly because so few species knew of his or the Time Lords' existence.

While he had resolved much of the survivor's guilt felt previously, the twelfth Doctor had begun to feel his age. Beneath his youthful veneer and outward playfulness was a very old man who had seen many terrible things. He felt a deep loneliness and his keen sense of loss led him to empathize with those who had also suffered. In some matters, his patience and capability for mercy and compassion had worn out or diminished. He was even aware of this trait, enough so to openly admit it and use it to intimidate his enemies. When River caught a glimpse into his mind, revealing that the Doctor was in pain, but, because of his nature, he couldn't tell anyone. The twelfth incarnation's more extreme emotional moments seem linked to making hard choices and the potential that innocents might suffer and die as a result of them. When it appeared he had to sacrifice the Jewish people in the Dalek camp in order to save Earth from the Daleks, he seemed disgusted with the situation and himself, remarking that he would have to change his name because he wouldn't be the Doctor any more.

The Doctor had a very hard time accepting defeat or failure. Having seen so much destruction he felt driven to try to prevent it where possible. River Song thought that if he lost this trait, the universe would become a darker place.

He had, like a number of his other incarnations, fantastic leadership qualities. He was extremely resourceful and quick thinking, able to spin things to his point of view, and could find positive outlooks in negative situations. He was somewhat more melodramatic in his brilliance. When thinking about a problem, he blocked out all outside distractions, to the point where he would tell a dying person "you're dying, now be quite" so he could solely concentrate on working out how to save them.

The twelfth incarnation shared many, but much milder, traits of the sixth and eleventh incarnations, such as the solemn nature when not being taken seriously and the belittling of humans. Also reminiscent is the lack of interest in his companions, much more than his previous incarnation's, even ignoring them when busy with his work. He also largely preferred his companions to follow his instructions but usually fell back to his previous incarnation's habit of letting his companions try their own plans.

Much like his fourth, sixth, ninth and eleventh incarnations, this Doctor was much more outwardly alien and wasn't as in touch with humanity as his fifth, eighth and tenth incarnation were. The twelfth incarnation believed that a human's ability to feel emotion defined their humanity. This incarnation was also aware of the flaws humans had and reminded them of those flaws at any opernunity given. He once out right atmitted that he saw humans as beneath him, yet still showed a deep respect for humanity, calling them an "extraordinary species" in the grand scheme of things and telling his enemies that it was dangerous to underestimate them.

The Twelfth Doctor would also have difficulty expressing himself emotionally, being reserved and stiff during these conversations. When he did lose control of his emotions, the outbursts were quite intense and he seemed to regret his actions and behaviour afterward.

Unlike the other Doctors, the twelfth believed in fate; the idea that most things happened for a reason, and that events in the universe were connected.

This Doctor's logical, analytical personality means he was too literal and he had a terrible sense of balance meaning he was not good at some sports such as skateboarding, football and basket ball.

Habits and Quirks
This incarnation of the Doctor appeared to have incredibly good eyesight as well as an eidetic memory, and was able to scan an entire scene and pick up little details. He implored others to observe every detail in an area and make brilliant deductions from doing so.

The First Doctor punctuated his speech with, "Hmmmm...?", exasperated sighs and snorts and the occasional mangled phrase or word. He would address young women as "child" and younger men as "my boy", or in Ian's case by his name.

He would often have jelly babies with him, and offer them as a greeting. While past and future incarnations also showed occasional fondness for the sweet, it was never as frequent as this incarnation's love for them.

He was also quite fond of puns. A habit occasionally displayed was a tendency to mangle and combine earth idioms, such as "A stitch in time... takes up space".

The seventh incarnation was a consummate fan of the game of chess, to the point of treating his companions and enemies as pieces on a chess board.

The eighth incarnation exhibited a habit of giving people, even strangers, hints about their future, while not expressing outright the nature of that future, with one exception.

This incarnation also had a tendency to repeat someone's name when he was trying to make a point, or when he got excited.

The Doctor also had quite a bit of experience in pick-pocketing, something unseen from any other incarnation and something the Doctor was unhappy about.

He often remarked that exotic technology or life is "beautiful" or "brilliant" and was genuinely enthralled by such discoveries, sometimes to the extent that he placed himself or his companions in danger. When this incarnation was faced with an occurrence that dumbfounded him he would repeatedly say "What?", increasing the expression on his face each time. While attempting to explain something he would often interrupt himself with a "Well..." and further elaborate what it was he was talking about (DW: Blink, et al) The Doctor was also fond of the phrase "I'm sorry, I'm so sorry", mainly talking to persons he knows are about to die and whom he cannot save.

This incarnation of the Doctor spoke in alien languages very often, using it to taunt the Sycorax Leader and communicate with the Tritovores and the Judoon.

This incarnation of the Doctor relied heavily upon his sonic screwdriver, pushing it to limits not seen in previous incarnations and even chiding his fifth incarnation for going "hands free". (DW: Time Crash) He also continued to heavily use the psychic paper. (DW New Earth et al) Like previous selves, he appeared to have the ability to carry a large and diverse number of objects in his pockets, stating once that they were bigger on the inside.

The Doctor also had the small quirk of intending to go to one destination, but walking in the opposite direction, leading to more than a few corrections from others. (DW: Army of Ghosts). This was similar to his sixth incarnation's habit of declaring to go one way but then going a different way. That, however, was more of a personal quirk than a bad sense of direction.

The Doctor often did math calculations in his head very fast. This included making an estimate, waiting for those around him to respond, then giving a very exact answer.

He also showed a penchant for talking with his hands, being able to calculate a situation with hand gestures. (DW: Flesh and Stone) He also had a habit of spinning in circles when walking and spinning around in a complete counter clockwise circle to look in one direction instead of turning to the right. (DW: The Eleventh Hour, The Big Bang)

This incarnation was also fond of bow ties.

Much like his tenth persona, this incarnation had horrible social skills. He went into detail about his encounter with Amy at Rory's Bachelor party, (DW: The Vampires of Venice) and often interrupted himself, and others, to tell someone to "shut up!" Also, this incarnation was frequently out-done verbally by Amy, to the point of becoming flustered at some of her wittier remarks.

He also had a habit of rambling, making rapid amendments to his speech, to the point where it seemed like he was talking nonsense.

A habit that seemed to mildly disturb the Doctor when Amy pointed it out to him was his propensity for tasting things in order to determine their chemical and mineral composition.

Skills
.

He once stated "I have the directional instinct of a homing pigeon".

More seriously, he had a gift for diplomacy and winning others over to his side. This particular facet of his personality enabled him to trick others into doing what he wished. Combined with his skill for improvisation, it is clear why the Doctor considered himself a "genius".

He also had a tendency to think aloud when he was panicking or stressed.
