Thirteenth Doctor (SAU)

"Who in the world am I? Ah, that’s the great puzzle."

- The Doctor

This incarnation of the Doctor is the thirteenth to bear his title, regenerating from his twelfth incarnation some time ago. He is the main protagonist of the 'Shachath Alternate Universe' timeline, along with his companion, Alice Ashdown and later, Maximillian.

Pre-Regeneration
The circumstances of the Doctor's regeneration into this form are never fully revealed, but apparently it occurred during the events that led to Clara Oswald's apparent death. The Doctor remains vague and skittish around the situation when asked and diverts the subject almost immediately.

Meeting Alice
When the Doctor was traversing around Edinburgh in 1890 (SAU: Empress of the North), he met a pickpocket vagrant girl named Alice Ashdown.

He blows her off initially when he accidentally gives gold coins from the Elizabethan times (which were in brand-new condition) to Alice's friend, Auld Burgess and she mistakes it as an insult to the old man.

Later on, their paths cross again when a Moroi believed to be the fabled 'Spring-Heeled Jack' kills Alice's best friend, Jane Saunders to steal her life energy and follow the creature to its ship - where the vampiric alien was feeding his crew stolen life energy from his victims so that they too could retain corporeal forms after their ship crashed and 'killed' them.

The Doctor offered the Moroi safe haven on another world where they could do no harm to other sapient creatures and their agent, Athicoth, who was responsible for the killings did consider it but was talked out of it by his starving brethren who were blinded by hunger and need to regain bodies again.

Alice is taken hostage and the Doctor demands her release but the Moroi promise to kill her if he did anything that would stop their plans. Alice, realising that Athicoth replicated the form of his first victim perfectly, incapacitates him by striking his groin and removing their leverage with the Doctor as a hostage.

As a result, the Doctor regrettably grafts an emergency transmat device onto the Moroi ship and beams it off into a far-off corner of space - knowing that the Moroi would starve to death.

Admiring Alice's want for justice and her unyielding sense of empathy, the Doctor invites her to travel with him and sees that she is also 'running from something', just like him.

Attack of the Mirror Monsters
The Doctor gives Alice's first taste of time travel by sending them forward from 1890 to 2014 in Edinburgh (SAU: The Looking-Glass People). He enthralls Alice with the blend of old and new and takes her on a tour of the modern-day version of her hometown.

However, the holiday is cut short when they see a man, Baxter Hart being chased by a trio of men. This causes them to discover a cabal of extradimensional creatures who use reflective surfaces to link their dimension with ours and cross over by taking over people's bodies if they stare too long at their own reflections.

Baxter leads them to a settlement of these 'Mirror Monsters' in the city and the Doctor and Alice infiltrate it. They see the Mirror Monsters are planning on causing a full-scale invasion on the planet's populace and the Doctor manages to stop them by discovering how to sever their link with our dimension after one of the monsters tries to possess him.

When the creatures observe a mirror shattering, the link is severed for them and they are forced back into their home dimensions. Using a series of bathroom mirrors, the Doctor forces out every Mirror Monster in Edinburgh and manages to purge all of them on the planet using a similar method to how he got rid of the Daleks and the Cybermen during the Battle of Canary Wharf. Using the possessed Baxter Hart while inside the TARDIS, the Doctor pinpoints every link to the mirror dimension and cuts them off simultaneously - ridding the planet of them all.

Being Involved in a Fixed Event
Still on Earth, the Doctor and Alice end up just outside Baltimore during the nineteenth century, where they meet famous horror writer Edgar Allan Poe (SAU: The Death of Edgar Allan Poe).

They discover that Poe has retreated to the woods in a secluded cabin and is being plagued by shades that seemed to be inspired by his fiction and these shades are becoming more real by the night.

The Doctor becomes frightful because he sees that they arrived not long before Poe's recorded death and explains to Alice the horrible nature of fixed time events and that whatever happens - Poe must die on the 7th of October.

Eventually, they discover the source of the shades is a damaged Myrion machine that projected dreams into holograms as a method of immersion therapy but the damage sustained when it crash landed caused the machine to behave erratically and latch onto Poe's mind, creating the shades.

In an attempt to deactivate it, the machine began going into overdrive and started to create stronger versions of Poe's shades and also create shades of the Doctor and Alice's nightmares. Alice sees a zombified version of her abusive father and the Doctor sees ' something he hopes never returns again'.

Finally, Alice manages to destroy the power core and disable the machine but the mental strain it causes on Poe became too much and the Doctor and Alice had no choice but to take him to where he would eventually die, raving and insane.

Finding Maximillian
Finally landing on an alien world, the Doctor takes Alice to a terraformed moon called Lom, orbiting a volcanic planet known as Hephaestus Prime (SAU: The Man in the Moon).

However, instead of the bustling metropolis Lom was so famous for being, the Doctor and Alice find themselves in a barren wasteland. Attacked by ravenous creatures known as Vagabonds, they are rescued by an insane cyborg called Maximillian.

Alone in this part of Lom, Maximillian was a former engineer for the city until the Cyber-Wars devastated the moon and has caused mutations like the Vagabonds to claim the land for themselves while he stays in his shack, completely alone which drove him to semi-madness.

However, thanks to the TARDIS' translation circuit, they see the Vagabonds are actually an intelligent race that fear Max for his brutality on them. Max is horrified by what he has done and asks for the Vagabonds to do their justice.

The Doctor, not wanting any more violence, protests but later pretends to go along with it if he is the one to execute Max. Tricking the vengeful mutants, the Doctor smuggles Max into the TARDIS where he believed the cyborg could be rehabilitated and even brought to some level of complete sanity again.

Personality
"He's both young and old. He seeks adventure like a child but knows the darkness like a soldier."

- Alice Ashdown

This Doctor is a lot more world-weary than most, haunted by whatever caused him to regenerate and lose Clara. He is not bitter or cynical like he was just after the Time War but he is still a fairly Byronic figure. His passion for travelling is laced with death and he sees a growing trend in how he must allow or even actively cause the destruction of many creatures. He hides a lot of his pain with an aloof eccentricity - acting unnaturally serene at times and making jokes when he really shouldn't be.

However, once the mask lifts, he can go from cold and hollow to his enemies to downright ruthless. His want for innocents to remain unharmed causes him to almost violently protect those he cares for most. He is all too aware of how close he is to going over the edge and fears it immensely as he knows that he is proceeding dangerously close to becoming an incarnation of himself he hopes will never come to pass.

To compensate for this, anyone he meets has his respect. He cares not for who someone is or where they are from so long as they do right by others. Disrespect for others earns his instant contempt though and he very rarely gives second chances unless for special circumstances.

Appearance
This is indeed one of the scruffier of Doctors. Unshaven stubble, with long dark hair and dark eyes. He is fairly tall and wears mainly long coats and formal attire with anachronisms here and there. His most common piece of clothing is his purple jacket, which he wears almost constantly.

Alice Ashdown
The Doctor admires Alice for her tenacity and her compassion for others. He feels linked to her in some way because like him, she gave up her aristocratic background and decided to 'run away' instead - helping out while she did.

They treat each other with mutual respect and the Doctor often seeks her counsel after certain traumatic events start to shake him. Alice in turn sees the Doctor as her greatest friend and finds his need to help to be his strongest attribute and that he should always remember that in the end, trying to do the right thing is better than nothing at all.
