Doom

Doom was the self-proclaimed "universe's greatest assassin", a member of the Lesser Order of Oberon. She owned a vortex manipulator.

Early life
Doom claimed to have been given the name by her mother, instead of choosing it as some kind of assassin nom de guerre. (WC: Meet Doom - the Universe's Greatest Assassin!) She once told River Song that she hadn't been born a killer, but that life had made her that way - claiming that although she didn't enjoy killing, she had to do it if she wanted to continue being herself. (COMIC: Target Selected) She told Alexyi Tennelo Kadh that she fell into being an assassin after her music career didn't pan out and she fell into a spot of bother. (PROSE: Extraction Point)

Doom eventually joined the Lesser Order of Oberon. She considered herself to be a very good assassin, claiming to be the best on the Lesser Order's books, although Order office worker Terri did not regard her as important. Her victories included overthrowing the Daedalus Conspiracy, sealing the Mandeville Dimension, and saving Princess Agatha from her seven deadly husbands, having had only one shot at each. (PROSE: Hour One)

She had been arrested several times on duty, but never staying too long thanks to her vortex manipulator. Doom had a job at the Jade Dragon Snow Mountain resort on Earth where they collided and went over the edge. Doom was able to save herself with her speed-riding wing. She had also faced a mutant crocodile whom she was hired to kill which triggered a primal fear within her, and had a hit within a goldmine more than a kilometer down. She had been hired to assassinate a mine owner because he laid off his workforce and replaced them with ore suckers.

One of her hits resulted in the genocide of a species of butterfly as she had been deceived in eradicating them in order for someone to terraform a planet. This resulted in her being reluctant about accepting jobs from government leaders. (PROSE: Extraction Point)

Unleashing Death
Having been assigned to kill a target at Duke Derek Gamma's Masked Ball on New Venice, Doom encountered the Doctor, who warned her that she was about to make a terrible mistake. Ignoring him, she killed her target with her staser rifle, and "everything went wrong" - causing Death to be unleashed upon her, which ensured her demise in only twenty-four hours, according to the life-signs reading on her vortex manipulator. Calling Terri at the Lesser Order of Oberon's headquarters, she asked for and obtained a new list of targets, hoping to run into the Doctor along the way so as to ask them how to save her life. Her first selection was a target in the Stormcage Containment Facility, as she knew that inmate River Song had a connection with the Doctor. (PROSE: Hour One)

As she started running, she sent out a video S.O.S. from a deserted planet, explaining her situation and asking anyone with the means to do so who received the message to contact the Doctor on her behalf. (WC: Meet Doom - the Universe's Greatest Assassin!) Contemplating the holographic timer display on her vortex manipulator, she reflected that she now had only 24 hours to find the Doctor. (WC: The universe's greatest assassin has just 24 hours to escape Death and find the Doctor - where will Doom's Day take her next?)

Searching for the Doctor
After dispatching her target at Stormcage, she sought out River Song, who empathised with her outlook on life and told her where she could find the Doctor - the Waxworks Museum on New Calamino. Thanking her, Doom selected a target at the museum and departed as the second hour of her day ended and Death began to close in once more. (COMIC: Target Selected) Arriving in the museum, she set to work searching for both her target - one Minister Scarling - and the Doctor. She encountered the latter in his sixth incarnation, disguised as a wax model. Working together, the two of them fended off a Nestene attack on the planet, melting Autons with molten plastic before destroying their source by pushing the corrupt minister into it, dispatching him. Doom made her plea to the Doctor, but he revealed that he was not the incarnation with the ability to help her, and that she would need to keep searching. The hour up, Doom set off for another target. (COMIC: The Plastic Population)

In a 1930s Hollywood film studio, Doom found no trace of the Doctor, instead discovering that every actor in the studio had been cyber-converted. Having run out of molten plastic, she fled the Cybermen, and sought her target - actress Polly Church - in hopes of quickly ending the mission. Finding that Polly, too, was now a Cyberman, Doom realised that her father had ordered her killing as a mercy, and obliged, detonating a crate of pyrotechnics in the prop room to destroy the Cybermen before departing. (COMIC: High Noon in Hollywood)

Arriving at a renaissance marketplace, Doom expressed dismay at the difficulty of her next target, finding that she had been tasked with killing the idea of the unicorn to prevent them being hunted to extinction. Setting off, she quickly located a market stall selling unicorn hair and horns, and offered a chest of prop gold in exchange for the entire unicorn, claiming to be a great hunter with a desire to add a unicorn to her list of kills. Jo Grant, independently in the process of trying to save the unicorns in the course of her travels with the Third Doctor, attempted to stop her, but she assured Jo that she was working towards the same goal. As the unicorn was presented to her by the stall's huntsman, she used one of her devices to disguise it as an ordinary horse with a fake horn, ending the people's belief in real unicorns. Having put a tracker on the huntsman, Doom said goodbye to Jo, setting off as Death closed in on her again. (COMIC: The Horn of a Dilemma)

Looking at the timer display on her vortex manipulator, Doom noted that, with 19 hours left, she had already faced Autons and Cybermen and met a few Doctors - but still had yet to locate the right one. (WC: Mission update from Doom!)

Doom's next target was at a masked ball in 19th-century New York. Investigating, she encountered Lord and Lady Prettypaw - whom she recognised as notorious thieves, and who were engaged in the process of breaking into a jewellery safe. Deducing that they had come for the Perpetual Topaz, a weapon of mass destruction which had been concealed on the primitive Earth, Doom utilised her mask as a throwing weapon to kill the Lord, before eliminating his sister with her staser rifle. Before leaving, she briefly encountered Missy, also in attendance at the party and attempting to play the role of "Doctor Who". Despite her claims, Doom immediately recognised that she was not the Doctor and told her as much, before departing for her next target - once again, located in the Stormcage Containment Facility.

Meeting with administrator Cire, Doom informed him that Stormcage was in danger thanks to her next target - an unknown party who had infiltrated the prison's staff with plans to hire out its worst prisoners to interested parties. She set off to find the person in question, only to find that Missy - irked by her remarks, and looking for the topaz - had followed her, intending to prove that she was in fact the Doctor. Doom, still failing to buy into her act, asked for identification, which Missy could not provide - causing Cire to grow suspicious of her as well and prompting him to call security. With the guards distracted, Doom began to search for her target, still trailed by Missy, and hacked into the cell of a prisoner, lowering the bars. Although this was not her target, her arrival caused the prisoner to inadvertently reveal the target's name. Doom thanked the prisoner, then proceeded to cut him in half with the re-activated cell bars, noting that he too was on her list. Encountering the correct target, unpaid intern Jaxxo, she killed him with her staser. She ran into Missy again, and refused to tell her what she had done with the topaz before departing for her next location.

At the 34th Annual Old Earth Convention at the Canis Major Overdensity Convention Center and Resort, at which she hoped the Doctor might be in attendance, Doom noted her love for convention shopping, planning to buy some rebar despite her strict schedule. Having done so, she soon encountered Missy for a third time. Initially mocking Missy's desire to prove herself as the Doctor, she eventually proposed a partnership - reasoning that, if Missy really was the Doctor, she should have no problem navigating a convention dedicated to their favorite planet. The two worked together to dispatch Doom's next target- an extremist with the Church of Omitted Yesteryear who sought to destroy all books originating from the old Earth - a feat which involved Missy knocking her out with an anatomical encyclopedia before Doom strangled her with string. Still refusing to reveal the location of the topaz, Doom went in search of her next mission.

On a dying world, Doom was tasked with killing a man who, as the last living member of his species, intended to kickstart a universal genocide using the topaz to ensure that his people would be remembered. Sharing tea with the man, Doom covertly poisoned his beverage - then, feeling that Missy's desire to convince her that she was the Doctor had begun to interfere with her mission, waited for the Time Lady to arrive before posing her a challenge - finding a way to avert the genocide and save the memory of the man's species in a non-violent manner, thereby proving herself to be the Doctor. Unable to do so, Missy gave up, just as the man died of the poison which Doom had given him. Although Missy claimed that she was, if not the Doctor, still a better upgrade, Doom told her that she needed the actual Doctor - then informed Missy that she hadn't poisoned her tea, as Missy was not yet a target. Having already incinerated the topaz and the man's weapons and replaced them with a hologram generated by one of her devices, Doom left the planet. (COMIC: A Doctor in the House?)

Noting that she now had 15 hours left to find the Doctor, Doom expressed confusion when the timer display on her vortex manipulator was suddenly replaced with a holographic image of a robot dog. (WC: 15 hours left to find the Doctor, and Doom receives an unexpected communication - from a very good boy!) Responding to K9 Mark IV's distress call asking for someone to nonviolently dispatch the Scarlet Scavengers attacking the robotic haven of Cal-Q-LOn for scrap parts, she agreed to assist in exchange for information about the Doctor. Doom dispatched the pirates, then arrived at the space station and introduced herself to K9 and the Thirteenth Doctor - but became suspicious of the latter after a few slips of the tongue suggested that she was a robot. Accusing them of this, she found that she had been correct when the "Doctor" revealed themself to in fact be Kamelion disguised as the Thirteenth Doctor, having taken that form to help fend off the pirates - although she was surprised to find that he was a shapeshifter, as she had expected a straightforward android duplicate. After a brief conversation about Kamelion's past, the pirates attacked again, but Doom revealed that she had arranged for a freighter of faulty parts, painted red, to be delivered to the Scarlet Scavengers - causing their ships to fail and forcing them to halt their attack. K9 promised to inform the Doctor of Doom's quest the next time they met, and Doom returned to the Time Vortex in search of another mission. She lamented her lack of success thus far, worrying that she would run out of time and suffer the consequences if she didn't find the Doctor soon, before her vortex manipulator located another target and prepared to make the jump. (GAME: AI am the Doctor)

Her next assignment was called VM2076 on the Svoda ski resort which required her to kill the target Stalgon, a planetary systems engineer from Vassta. She had spoken to Mandra, a representative of the client that hired her services. Mandra wanted Doom to make it look like an accident similarly to a previous hit of hers. This plan failed when Doom was attacked by what turned out to be androids which slowed her enough for Stalgon to make a getaway. Leaving the gondola she saw a giant asteroid heading towards the planet. She met up with Mandra again who began attacking her and when hit with a staser also turned out to be an android. She fought more androids to get to Stalgon, witnessing the destruction of the asteroid as she did so before reaching him. She eventually caught up with him and shot him and the console that housed his conversation partner, a Kraal. Looking for something to eat and research her next hit, she bumped into the Ninth Doctor. Before she could get answers both on her situation and the asteroid, she was whisked to her next hit on Satellite Five (PROSE: Extraction Point) but not before taking a moment on the planet she visits regularly. (WC: A satellite over Earth with the number 5 on it…)

Arriving in the year 200,003, her search for the ethereal led to her encounter with producer Andre Kulekvo who offered her a chance to eliminate her ghostly target on his show Ghost v Whatever. She was able to lure the target, Alexyi Tannelo Kadh, the ghost version of a ship's systems, into the life designed to trap and kill ghosts but found herself trapped in the lift as part of the show's entertainment. The two were able to escape, with Doom wanting to kill Andre for what he did. However the duo found that he had already died, making Doom the prime suspect. Alexyi set up a hit for the asteroid that threatened his planet Vassta and offered to power down so that her hit would be a success. She accepted it, got herself healed and left Satellite Five.

Adoring a spacesuit, she appeared within the asteroid and was surprised to find cave paintings, and planned to lay down fission spikes before being attacked by cockroaches. As they climbed her she fought to get them off when the Doctor grabbed her hand and ran. Coming to a halt, she meets Kat, a Vassta native who came with the Doctor and resembled Mandra. Kat attempted to convince the Doctor that they shouldn't destroy the asteroid as it's a nest for an intelligent species of insectoids and destroying it would be genocide but he wasn't convinced. Kat pulled a gun on the Doctor and then Doom demanding information on who hired her before the asteroid began to crack revealing the surface of Vassta. The Doctor told Doom to continue with her plan to destroy the asteroid. He planned to use the TARDIS' tractor beam to pull it whilst Doom continues her plan, fending off cockroaches, before finding out they were robotic. Using its circuits she tracked down a spaceship at the asteroid's core directing the asteroid to Vassta. On her way back she was confronted by Kat alone who revealed herself to be the one behind Doom's previous two hits. Doom deduced Kat to be a Mahd and behind the attempt on Doom's life and the murder of Kulekvo. When the asteroid broke more they became separated and she presumed Kat to be dead. Researching into her last hits she saw they were issued by a company called Slitheen, Slitheen & Slitheen, S.A. The Doctor returned with the TARDIS to rescue her and set the asteroid to crash into the sun. Before picking another hit, the Doctor offered to take her out for coffee.

The Doctor extended her timer by five minutes, took her to a Starbucks and told her to continue pursuing the Slitheen family threat. She accepted two simultaneous hits on the real Vassta but before she left she saw Death once more. She escaped in time, arriving on the Svoda 3 resort and was on the guest list when Draja Fel Fotch Heppen-Bar Slitheen appeared on stage announcing that Abo Chenoute Mahd and Luudmila Kadh, Doom's targets, were dead and that the future of the planet was uncertain. Doom saw why as they were using ore suckers to mine the planet. Doom tracked Chenoute who was recording a video to sew division between the two factions on the planet, wherein she shot them and revealed to be Ecktosca Fel Fotch Heppen-Bar Slitheen. She punched out the hit on Chenoute and spoke figuring out that the Slitheen's clients hired them to do all this to mine azbantium. The TARDIS then landed, but surprisingly Android Stalgon and another Doctor stepped out. Doom went off to find Luudmila who was recording her "confession" to cause more divide. She attempted to be diplomatic with the Slitheen but eventually fought her and ran out with Stalgon. They trapped the Slitheen before Stalgon revealed himself to be an android who wanted revenge. The Doctor saved her and reprogrammed the android to help them. She eventually met the clients who hired her to assassinate the leaders to cause divide on the planet and while wanting them arrested, she decided to help reunite the planet instead. The Doctor showed her what they did to the future of the world and asked her to vouch for him before leaving. She accepted her next hit and departed Vassta. (PROSE: Extraction Point)
