The Slitheen were a family of Raxacoricofallapatorian criminals. The Slitheen were rivals (and "cousins") of the Blathereen family, (TV: The Gift) cousins of the Rackateen family and descendants of the Slavereen who were descended from the Changleen family, the earliest descendants of the Huspick Degenerate. (WC: Monster File: Slitheen) The Slitheen family made a habit of going to Earth in attempts to salvage it to make money. (TV: Boom Town, Revenge of the Slitheen)
Early history Edit
The Slitheen were from Raxacoricofallapatorius originally and bribed their way into government. Their rule crashed the planet's economy and eventually, the population rose up against them. (TV: The Gift) The entire family was tried and found guilty in perpetuity and sentenced to death. (TV: Boom Town) The Judoon forced the Slitheen out and many of them fled justice. (TV: Revenge of the Slitheen)
In 102, the Slitheen were among the factions who joined the Alliance. They came to Stonehenge and helped imprison the Eleventh Doctor in the Pandorica to save the universe. (TV: The Pandorica Opens) When the plan failed, they were turned to dust and removed from the universe along with the rest of creation. They were returned when the Doctor "reset" the universe. (TV: The Big Bang)
21st century Edit
In March 2006 the Passameer-Day branch disguised themselves as various humans holding leadership positions and attempted to seize control of the British government in an effort to start a nuclear war. Their ultimate aim was to turn the Earth into a huge nuclear reactor pile and sell its remains off as starship fuel. This attempt was foiled by the Ninth Doctor when he ordered Mickey Smith to shoot down Downing Street with a missile. (TV: Aliens of London, World War Three)
Blon Fel-Fotch Passameer-Day Slitheen survived; having teleported to the Isle of Dogs. Later the same year, in September, Blon managed to get herself elected Mayor of Cardiff, and tried to abuse her position in an attempt to escape being stranded on Earth by destroying a local nuclear reactor. The Cardiff Space-Time Rift would amplify the explosion so it would not only destroy Earth but enable her to escape the planet safely on her tribophysical waveform macro-kinetic extrapolator. This effort was also foiled by the Doctor and his allies when the Doctor used his sonic screwdriver to reverse Blon's teleport. When she tried to use the TARDIS as a secondary explosion, Blon was reverted to an egg by the heart of the TARDIS and returned to her home planet to be given a second chance at life. (TV: Boom Town) Renamed Margaret, after her human identity, Blon was adopted by the Jingatheen family. (COMIC: A Confusion of Angels)
Around March 2007, The Lutiven-Day Branch of the family took over a building company called Coldfire Construction and placed transducers around the Earth to absorb the Sun's energy, destroying the Earth and avenging the Passameer-Day members who died. After doing so, they intended to buy a fleet of ships to destroy the Grand Council of Raxacoricofallapatorius.
As Luke didn't anticipate them draining the Sun, the machine overloaded, and they were forced to switch it off. Luke began to reset the system, but his mother Sarah Jane handed him her sonic lipstick, and he shorted out the machine. Several Slitheen were accidentally killed in this incident, including Kist Magg Thek. (TV: Revenge of the Slitheen)
Having teleported away, later in 2008, Kist's twelve-year-old son Korst Gogg Thek Lutiven-Day Slitheen (who had used a teleporter to escape the school) teamed up with two other adult Slitheen and the Xylok Mr Smith to seek revenge. Mr Smith had secretly been manipulating the Slitheen to power Luke's mind with MITRE, bringing the Moon crashing into the Earth. With a mutual enemy, the Slitheen reluctantly teamed up with Sarah Jane and provided her with a teleport so she could reach Mr Smith. The Armageddon virus was successfully uploaded into Mr Smith with help from K9 Mark IV to stop the plot and the Slitheen departed without further conflict. (TV: The Lost Boy)
At some point in 2009, a member of the family took the body of Ambassador Rahnius of the Galactic Alliance and attempted to steal K9 from Sarah Jane. (TV: From Raxacoricofallapatorius with Love) Later, two more Slitheen would attempt to crush the Earth into a giant diamond; they were thwarted and captured by two Blathereen, who sentenced them to death. The Blathereen would later be revealed to be Slitheen-Blathereen, a family descended from both families and with the morals of the Slitheen side. Their intervention in the Slitheen crisis was to put into action their own plot. (TV: The Gift)
One Slitheen was captured by the Krulius and stored in a data-pod. The Krulius later used his digital bio-converter to upload the Slitheen's bio data onto the internet. There it was found by Mr Smith, Rani Chandra and Clyde Langer who sent the Slitheen back to his original place. (COMIC: Monster Hunt) Another Slitheen was kept at the Doloth Star Base. When the Judoon caught the Krulius all his captured aliens were set free. However, the Krulius had managed to take clone cell samples of his former captured aliens with him, which allowed him to grow perfect copies of these aliens. (COMIC: Return of the Krulius)
In late 2010, two Slitheen took part in the army of alien slaves led by the Krulius to attack Sarah Jane's house. When Clyde defeated several of the aliens, the Slitheen regrouped with the army and the Krulius ordered them to retreat. Sarah Jane thought that the aliens in the army were under some kind of hypnotic influence. (COMIC: Defending Bannerman Road)
In the late 2010s, the clan Klep-Clotch Slitheen disguised themselves as a Military Tattoo in an attempt to steal hidden treasures from Edinburgh Castle. Their plans where ultimately thwarted by Lady Christina de Souza and Sam Bishop. (AUDIO: Death on the Mile)
Later 21st century Edit
Post-21st century Edit
After these attempts, their fortunes started to wane. They were put out of business by the Blathereen, who were cheaper and more effective. In the year 2501, Ecktosca and Dram discovered the activities going on in Justicia and attempted to take over the operations. They were captured but later escaped with the help of the Ninth Doctor. After the death of Don Arco, they stole the surviving warp-hole technology to rebuild their fortune. (PROSE: The Monsters Inside)
By the 347th century, the family were still exiled from Raxacoricofallapatorius, although they expected a reappraisal in the coming 1000 years. They were also involved in the Platonic War, being among those defeated by the humans. As a form of revenge, they travelled back to an early point in human history, when Greece was facing famine. They gave them food, in exchange asking for champions to fight for them. The Slitheen were actually running a temporal tourist tour, with aliens coming to see the sites of future monuments and with the human fighters being killed for their entertainment. Their eventual plan was for the humans to become too dependent on them, never develop technology and never develop an advanced civilisation. The Tenth Doctor and June tried to stop them peacefully, but instead, the native Greeks fought back, destroying their time travel technology and throwing the whole organisation into chaos. Mamps, Cosmo and Leeb Slitheen escaped but were trapped in the past. When their time-travel package tour appeared to kill a tourist, they were taken to court and bankrupted, with police being sent back to capture Mamps, Cosmo and Leeb. (PROSE: The Slitheen Excursion)
At an unknown date, the Slitheen were among many species present at Trenzalore after being drawn there by the Time Lords asking the Question from another universe. The Slitheen took part in the Siege of Trenzalore but they either retreated or were killed in the fighting which took place when the Daleks bypassed the Papal Mainframe's planet-wide force field and the other fleets followed them in their wake to the planet's surface. (TV: The Time of the Doctor)
Alternate timelines Edit
In Andrea Yates' World, where the Trickster manipulated events so that Sarah Jane Smith died in 1964, the Slitheen whom Sarah Jane defeated at Park Vale Comprehensive School never came to Earth. As the Trickster explained to Sarah Jane while she was in limbo, he had turned away all the foes she would have defeated, his intention being for her absence to allow Earth to be destroyed by the meteorite K67. (TV: Whatever Happened to Sarah Jane?)
In an alternate dimension in which the Doctor's adventures existed as a fictional TV show called Doctor Who, a fan dressed as a Slitheen was present at a Doctor Who convention which the Eleventh Doctor visited with Ally in 2013. (COMIC: The Girl Who Loved Doctor Who)

(TV: The Nightmare Man)
Cultural details Edit
The Slitheen placed great importance to hunting, including the hunting of sentient prey. (TV: Revenge of the Slitheen) Indeed, they were all born hunters. In a Slitheen family tradition, they buried the eggs of their young deep underground in caves, so that they would hatch, quite alone, and have to burrow their way out to survive. Newborn Slitheen thus came into being with no food, guidance or sunlight. Not all survived this ritual. (AUDIO: Sync)
According to Bloorm Vungah Bart Slitheen, the bartleboigle tree was used to discipline children by spanking their backsides. (TV: The Lost Boy) Blon said that the Slitheen used Venom Grubs to dispose of family members not willing to engage in criminal activities. (TV: Boom Town)
When one or a group of Slitheen found themselves in a confrontation with multiple individuals, a common tactic was to grab one of them by the neck and threaten to kill them unless the others followed their demands. (TV: Boom Town, The Lost Boy, The Gift)
The Slitheen had developed a method of disguising themselves as humans by first obtaining the skin of a dead human - referred to as a skin suit - and compressing themselves into it. In order for this to work the human victim needed to be heavy set, and the compression had a side effect: a gas exchange occurs which causes the disguised Slitheen to frequently expel gas with a sound similar to human flatulation. (TV: Aliens of London, Revenge of the Slitheen) By late 2008 the compression field technology was improved to allow Slitheen to assume a greater variety of human body types, and the gas-exchange issue was eliminated. (TV: The Lost Boy) However, the Slitheen didn't invent this technology, they stole it from the Blathereen family. (PROSE: The Lost Boy) It wasn't always initially used, (TV: From Raxacoricofallapatorius with Love, The Gift) but would remain the standard until at least 2501. (PROSE: The Monsters Inside)
Rose Tyler wondered if the newly regenerated Tenth Doctor was a Slitheen. (TV: Children in Need Special) While attempting to bluff the Sycorax into leaving Earth alone, Rose later tried to invoke the authority of the "Slitheen Parliament of Raxacoricofallapatorius", among other species she had encountered on her travels. (TV: The Christmas Invasion) Rose once remarked that the Abzorbaloff looked "a bit Slitheen". (TV: Love & Monsters)
Sarah Jane Smith was congratulated by Jack Harkness on her defeats of the Slitheen. (TV: The Stolen Earth) Luke told Sarah Jane, Clyde and Rani that his friends at the University of Oxford lived off baked beans and curry. Clyde remarked that it must be like living with the Slitheen. (TV: The Vault of Secrets)
When cyborg hacker Psi was attempting to protect Clara Oswald from the Teller, he ensured that it would focus on his guilt by uploading the memories of some of the worst criminals in history, one of them being the Slitheen family. (TV: Time Heist)
Behind the scenes Edit
Attack of the Graske Edit
A Slitheen appears in NOTVALID: Attack of the Graske, a story this wiki does not consider to be a valid DWU source as it has multiple endings, which we cannot qualify through any mechanism which is the "correct" or "canonical" one.
In Attack of the Graske, an unnamed Slitheen was captured by the Graske and replaced by a changeling. When it broke free from its prison it chased a Graske. A companion of the Tenth Doctor could then choose from two fates for this Slitheen, either freezing it in place forever or returning it home.
The Visual Dictionary Edit
Monsters and Villains Edit
According to the reference book, Monsters and Villains, which this wiki does not count as a valid source, the Slitheen continued to be hunted down by the Judoon and Wrarth Warriors after leaving Raxacoricofallapatorius.
Other matters Edit
- Of all the aliens created for the revived series, the Slitheen have been featured the most, having appeared in six television stories, two books and one short story.
- The Slitheen are the only aliens from the main series to have appeared more times on-screen in a spin-off show, having been featured in only four episodes (including the cameo in The End of Time) of Doctor Who, yet appearing in six episodes (and one Comic Relief special) of The Sarah Jane Adventures.
- The Slitheen are not created using CGI technology, but are mechanical prosthetics. (CON: Why on Earth?)
- The Pete's World counterpart of the Slitheen were planned to appear in the scrapped Rose Tyler: Earth Defence spin-off.
