3-D glasses

Anaglyphic 3D glasses are used as detectors for radiation created by the Void in the world of Doctor Who

The Tenth Doctor used red-blue anaglyphic 3D lenses to examine the Void ship and the "ghosts" in "Army of Ghosts". The glasses enable the wearer to see the "Void stuff", background radiation from the Void which surrounds and infuses an object or person that has crossed between parallel universes.


500 year diary

First appears in the Second Doctor serial The Power of the Daleks

900 year diary

Seen among the Seventh Doctor's belongings in the TARDIS in the Doctor Who television movie.



A blue liquid that the Ninth Doctor carries as a weapon against the living plastic body of the Nestene Consciousness in "Rose". It appears to break down plastics chemically, without any effect on other materials.

Anti-Regeneration Gun

In "Last of the Time Lords", Martha Jones claims that the Torchwood Institute and U.N.I.T. created a gun and four phials of coloured chemicals, which, when slotted into the gun and injected into a Time Lord, will kill the Time Lord and prevent regeneration. After the Master destroys the gun with his laser screwdriver, Martha reveals that the weapon is a fake, a ruse to conceal her actual mission and to engineer her return to the Valiant.

Archangel Network

A worldwide mobile phone satellite network (composed of fifteen satellites) seen in "The Sound of Drums", the Archangel network creates a global low-level telepathic field which allows the Master to subtly influence the behaviour of the world's human population. It was first used to convince a substantial number of the British public to vote for his Mr. Saxon persona—individuals not affected included Clive Jones and Vivian Rook. It was later used to keep most of the human race afraid of the Master. The network also masks the Master's Time Lord nature from the Doctor. In "Last of the Time Lords", the Doctor uses the network to channel the combined psychic energy of the entire human race, after Martha had convinced them to think of the Doctor by name at the same moment.

Astral Map

A device which the First Doctor has on board the TARDIS. In The Web Planet, the Doctor was going to use his Astral Map to help the Zarbi "queen" find the Menoptra "invasion force".



A metal that Rose Tyler gives to her mother in "Army of Ghosts". It can be used to predict the weather, warming up when it will be hot and cooling down when it is about to rain.

Black Scrolls of Rassilon

From The Five Doctors, these contain forbidden knowledge from the Dark Time of Gallifrey, the home of the Time Lords. Their discovery falsely implicates the Castellan in the abductions of the Doctor and others.



An item intended to screen the wearer from certain kinds of detection. A biodamper resembling a ring is placed on Donna Noble's finger in "The Runaway Bride", but the Doctor later realises it is ineffective, because Donna had been infused with Huon particles.

Blue crystal

In The Green Death, the Third Doctor takes a perfect blue crystal from the planet Metebelis Three, which has the ability to focus and amplify thoughts. He gives it to Jo Grant as a wedding present, but she sends it back to him in Planet of the Spiders, setting in motion a series of events that end with the Doctor's regeneration. In Destiny of the Doctors, the Doctor had a similar crystal hidden in a greenhouse within his TARDIS. Graak had to find it and give it to the The Master in order to continue his quest to save the seven incarnations of the Doctor.



The Fifth Doctor wears a sprig of celery in his lapel. He claims that he is allergic to certain gases in the praxis range. If those gases were present, the sprig would turn purple, whereupon he would eat it. Actor Peter Davison asked for this explanation to be included in The Caves of Androzani as it was his final story. It was referred to later in the same story by the Doctor as "a powerful restorative where I come from..." The Doctor first affixes the celery in Castrovalva, and replaces it in Enlightenment. The Tenth Doctor teases his earlier self about the celery (referring to it as a "decorative vegetable") in the Children in Need special "Time Crash" (2007). A piece of plastic celery from the series fetched £5,500 for charity when it was sold at auction in November, 2007.[1]

Chameleon Arch

The Chameleon Arch

The Chameleon Arch is a device that rewrites every cell of an individual to a specific species. The conversion, which causes extreme pain, also provides a set of false memories to match the new persona. The Tenth Doctor uses it in "Human Nature", enabling him to hide from the Family of Blood in 1913 as the school teacher, John Smith. He retains a small amount of "residual awareness", resulting in dreams about his life before the change. The Chameleon Arch stores the Doctor's Time Lord identity in a fob watch that slots into the device as it is operated. In "Utopia", Martha discovers that The Master used the same process, generating "Professor Yana" as his persona.

Chameleon circuit

A component of a TARDIS which allows it to change shape to match its surroundings and remain inconspicuous. The circuit on the Doctor's TARDIS has malfunctioned, leaving it stuck in the shape of a 1950s-style British police box. Attempts to repair the circuit have led to unpredictable results, including the TARDIS taking on the form of a pipe-organ (on which the Doctor plays a few notes of J.S. Bach's Toccata and Fugue in D minor). Since these episodes, the Doctor has said that he has become fond of the police box form, and so has stopped trying to repair it. The TARDISes owned by the Master, the Rani, and the Meddling Monk had fully functioning chameleon circuits. In the episode "Journey's End", when Donna Noble has the Doctor's knowledge in her head due to an instantaneous biological metacrisis, she starts to tell the Doctor how he can fix the chameleon circuit, but does not finish as the knowledge in her head overwhelms her.

Charged Vacuum Emboitment

Abbreviated CVE, this is part of a system created by the mathematicians of Logopolis to allow the universe to survive past its point of heat death by shunting excess entropy into other universes (Logopolis). The Fourth Doctor and Romana unwittingly travel through a CVE into a parallel universe known as E-Space at the start of Full Circle.

Cloister bell

An alarm that tolls, in the manner of a heavy church bell, in the TARDIS to warn the crew of impending disaster. It usually signifies a problem with the fabric of reality, such as a paradox or alternative realities bleeding together. First heard in Logopolis, it rings again in Castrovalva, Resurrection of the Daleks, the 1996 television movie, the 2005 Children in Need special, "The Sound of Drums," "Time Crash" and "Turn Left", and in the final scene of "The Waters of Mars".

The commentary on the Logopolis DVD says that the sound of the bell was produced by lowering a gong into a vat of water to deaden the reverberation.

Compression field

A device worn around the necks of the Slitheen so they may shrink themselves down slightly, allowing them to fit in the skinsuits of people slightly smaller than they are. It causes the release of pent-up energy in a manner that mimics flatulence. In The Lost Boy, the Slitheen use an improved version of this technology which allowed them to disguise themselves in smaller bodies.

Coronet of Rassilon

Worn by Borusa in The Five Doctors, it allows the wearer to impose his will on others, though it can be resisted.

Crystal of Kronos

From the Third Doctor serial The Time Monster, this is used by the Master to power his TOMTIT machine, but turns out to be much more powerful.


Data Ghost

A Data Ghost is a short-lived imprint of the consciousness of the user of a Lux Industries spacesuit, created at the moment of death by the suit's built-in communications unit, which links to the user's nervous system to allow thought-based communication. The concept first appeared in "Silence in the Library", when a member of Professor River Song's archeology team, Miss Evangelista, is killed by a swarm of Vashta Nerada. Consciousness remains active in the device for a few minutes, and then the individual's last thought repeats in a loop until the device is shut down. In "Forest of the Dead", the Doctor finds out that the sonic screwdriver he gave to Professor Song in the future contains a neural relay that stored her data ghost into the device when she died rescuing the 4022 people trapped inside the library's computer. He uses the screwdriver to store her Data Ghost in the computer, whereupon she is "resurrected" and can live on forever inside the computer, along with Miss Evangelista and the other members of her team who were killed by the Vashta Nerada.


The material out of which Dalek casing is made. It is first mentioned in the First Doctor serial The Dalek Invasion of Earth, and is also referenced in Day of the Daleks and "Daleks in Manhattan".

Dalek-enhanced Thompson submachine guns

As seen in "Evolution of the Daleks", the Dalek Humans used these weapons to kill Dalek Thay and Dalek Jast. They function in the same manner as a standard Dalek weapon, but seem to be inferior in terms of firepower. These also appear in the opening montage to the Torchwood season 2 episode "Adam".

Deadlock seal

A deadlock seal is a type of locking mechanism introduced in "Bad Wolf" that sonic devices, such as the Doctor's sonic screwdriver, cannot open. Deadlock seals are often used as a plot device to prevent the Doctor from using his sonic screwdriver to easily escape or otherwise defeat his opponents. The TARDIS can also be deadlocked, preventing entry even with a key; it does not, however, prevent the sonic screwdriver from interfering with the ship itself; in "Utopia", the Master exploited this to steal the Doctor's TARDIS.

Decadron Crucible

As seen in Pyramids of Mars, a decadron crucible is a temporary containment device that materializes around an unsuspecting person. It looks like a large, acrylic glass cylinder with air vents for the victim. The device has two switches on the front—both shut off the device, but only one does so without killing the occupant.

Delta Wave

A delta wave is a brain wave associated with deep sleep. The Fifth Doctor builds a delta wave augmenter in Kinda to help Nyssa sleep.

In "The Parting of the Ways", the Ninth Doctor builds a delta wave projector to use against the Daleks, but does not activate it. The projector generates a wave of "Van Cassadyne energy" that will destroy the brain patterns of all living creatures within its field of effect. It can be refined to affect only certain species.

De-mat gun

A Time Lord weapon from the serial The Invasion of Time that can remove its target from space-time altogether. It cannot be armed without the Great Key of Rassilon.

Dimensional Stabiliser

A component of TARDIS circuitry that bridges between the outerplasmic shell and the internal space of the ship's interior. In The Armageddon Factor, the dimensional stabiliser is used to shrink the Doctor and Drax.

Dimension Vault

A piece of Dalek technology stolen by the Cybermen, they used it to escape the Void; it is covered with Dalek bumps and contains a gun. The gun needs to be charged for some time before it can be used. The Doctor uses the Dimension Vault's gun in "The Next Doctor" to teleport the Cyberking into the time vortex to break apart safely.

Doomsday Weapon

In the serial Colony in Space the Time Lords sent the Third Doctor on a mission to recover this weapon, the plans for which the Master had stolen from Gallifrey.

Dwarf-star alloy

A super-dense material obtained from white dwarf stars in the serial Warriors' Gate. It is used as a building material in the hulls of spaceships and can also be used to contain temporally sensitive beings. In "The Family of Blood", the Doctor imprisoned Father of Mine in chains made of this material.


In The Krotons, a machine created by the Krotons that transforms mental power and intelligence into energy.


Edible ball bearings

In "Fear Her" the Tenth Doctor admits that edible ball bearings—silver dragées—are amazing and that no other species in the universe has created such a thing. At the end of the episode Rose gives him a cupcake decorated with silver dragées.

EMP unit

A cylindrical device used in "Voyage of the Damned", taken from Bannakaffalatta's cyborg body as the only effective weapon against the Host. It produces an electromagnetic pulse which neutralises the robots, but must be periodically recharged. A similar device, built as a grenade, appears in the episode "The Age of Steel", where it serves to neutralise a Cyberman. The EMP inadvertently disables the Cyberman's emotional inhibitor, allowing it to remember who it was prior to conversion. This led the Tenth Doctor to deactivate the robot body and kill the victim with the sonic screwdriver.

Everlasting matches

Everlasting matches first appeared in the Target novelization Doctor Who and the Daleks, in which the First Doctor states that they are "an invention of his". They subsequently appeared in the Virgin New Adventures novel Sanctuary, the Virgin Missing Adventures novel Venusian Lullaby and the Telos Publishing novellas Time and Relative and The Cabinet of Light. The latter includes a brand name Promethean Everlasting Matches, made by the Eternity Perpetual Company (which also made the everlasting generators in Carnival of Monsters).

The Doctor carries a box of everlasting matches in the New Series Adventures novels The Resurrection Casket and The Nightmare of Black Island. In The Resurrection Casket he explains they are made from Umbeka wood, which comes from the planet Umbeka, where winter lasts for centuries, and the summer is very hot and only last a couple of weeks. The heat from the flame makes the wood grow as fast as the flame consumes it, so the match never burns down.

Eye of Harmony

The Eye of Harmony is an artificially-created black hole made by Omega, used by the Time Lords as a power source for time travel.


Field Gravity Detector

In actuality a yo yo, this is used by the Fourth Doctor to determine the presence, magnitude, and direction of gravity in a given area.


A necklace from "The Unicorn and the Wasp", it is connected to the Vespiform, and was used to kill it by Donna Noble by throwing it into a lake. An additional "monster file" on the BBC's Doctor Who website revealed the firestone was found in the lake, and sold at auction to a gentleman in a greatcoat.

Fob Watch

A fob watch, engraved with Gallifreyan symbols, used to store the memories and biology of a Time Lord who uses the Chameleon Arch. The watch uses a perception filter to prevent the transformed Time Lord from noticing it. Those with telepathic abilities are apparently immune to the filter, as are those already aware of the watch's nature. The Family of Blood can also smell the Time Lord stored within. When opened by the Time Lord, it restores their original physiology. Anyone else opening it gets flashes of the memories stored within. In the 2008 Christmas Special, "The Next Doctor" (David Morrissey) is discovered to own a fob watch, which the Doctor suspected to be a Time Lord watch. Although it is soon revealed to be a normal fob watch, it helped to identify Morrissey's character as Jackson Lake, a normal human.


Ganymede driver

A device from the fourth Doctor's toolbox that he requests from Sarah Jane Smith at the end of "The Hand of Fear."

Gas mask

An ordinary gas mask from The Empty Child. Jamie, the child of the title, wore a gas mask. The nanogenes, the cause of the entire problem, grew gas masks on the people affected.

Genesis Ark

A Dalek-shaped prison ship created by the Time Lords to store millions of captured Daleks, introduced in "Doomsday". Like the TARDIS, it is bigger on the inside, containing millions of prisoners yet being only large enough to release one Dalek at a time. It is sucked into the Void after the Doctor opens the breach.

Giant brain

A creation of the Rani in Time and the Rani, it was linked to the minds of several geniuses, such as Albert Einstein, Louis Pasteur, and Pierre Curie.
A giant brain also appears in the 2008 episode "Planet of the Ood"; in this case, it is part of the gestalt mind of the Ood.

Grachtian statue

Seen in The Androids of Tara. An important symbol to the family of Count Grendel. One of the pieces of The Key to Time in disguise.


A device installed on the Moon in the 21st century to control Earth's weather. In The Moonbase, the Cybermen attempted to gain control of the device in an attempt to destroy Earth. The Second Doctor managed to stop the Cybermen by using the Gravitron to send them and their ships into space.

Great Key of Rassilon

A constituent part of the De-mat gun, its location is known only to the Chancellor of the High Council of Time Lords. It is not to be confused with the Key of Rassilon or the Rod of Rassilon, also known as the Great Key.

Great Seal of Diplos

Seen in The Stones of Blood, an important artifact stolen by the criminal Cessair of Diplos. It was actually one of the pieces of The Key to Time in disguise.


Hand of Eldrad

In the Fourth Doctor serial The Hand of Fear, the hand was the only surviving part of the Kastrian creature Eldrad, found by the Doctor and Sarah in an English quarry.

Hand of Omega

The Hand of Omega is a device which can collapse a star into a black hole.

Harp of Rassilon

From The Five Doctors. One of the many artifacts with Rassilon's name on it, the Harp of Rassilon is accompanied by a painting that shows Rassilon himself playing it. Upon seeing this the Fifth Doctor comments that he did not even know Rassilon was musical. Playing the tune notated on the sheet music in the painting unlocks a secret door leading to the Time Scoop controls.

Huon particles

The Doctor activating a vial of Huon particles

Ancient particles from the Dark Times. They are potentially deadly and contain a great amount of energy. Huon particles will magnetise with other sets of Huon particles, causing people to inadvertently teleport. A remnant of them exists in the heart of the TARDIS.


A crystalline substance in The Horns of Nimon. The crystals provide power for spaceships and cities.

Hypersonic Sound Wave Manipulator

A genetic manipulation device created by Professor Richard Lazarus in the "The Lazarus Experiment" to reverse ageing. The 76-year-old professor becomes a young man after using the manipulator, but the process awakens dormant genes, causing him to mutate into a monstrous, insectoid creature, capable of extracting the life force from humans. Funding for the project was provided by Mr Saxon who is later revealed to be the Master. The technology is later incorporated into his weapon which he calls a laser screwdriver in "The Sound of Drums" and is used to incapacitate the Doctor by aging him.


Ice gun

A fire extinguisher used by the Tenth Doctor to immobilise the Clockwork androids in "The Girl in the Fireplace". The name "ice gun" was suggested by Mickey Smith, played by Noel Clarke. The Doctor called it a fire extinguisher. According to Clarke, speaking in the Doctor Who Confidential episode "From Zero to Hero", the art department labelled them with the warning "Do not use to cool drinks, freeze food, win arguments, or create Christmas grotto decorations."


Info-stamps are storage devices created by the Daleks. Cybermen that escaped the void used stolen info-stamps containing information about many subjects, including the Doctor. When Jackson Lake ("The Next Doctor") looked into an info-stamp, details about the Doctor were embedded in his memory and he came to believe he was the Doctor's next incarnation. The info-stamp backfired, leading the Cybermen to also believe that Lake was the Doctor. Info-stamps can be used as weapons by removing the cover and releasing an electromagnetic pulse.



A mineral in The Horns of Nimon. If used to power a weapon, that can stun or kill a Nimon.

Janis thorn

A poisonous weapon of the Sevateem, used by Leela much to the Fourth Doctor's disapproval. Seen in The Face of Evil and The Talons of Weng-Chiang, and mentioned (but not seen) in The Pirate Planet.

Jathaa beam weapon

A weapon reverse-engineered from a ship called the "Jathaa sunglider" is first seen in "The Christmas Invasion" (2005), where it is a powerful beam weapon used to wipe out a Sycorax ship. Torchwood One director Yvonne Hartman first tells the Doctor the origins of the weapon in "Army of Ghosts" (2006), and a scaled down version of the same weapon is seen in 2008 Doctor Who episode "The Poison Sky" aboard UNIT's aircraft carrier the Valiant and used to attack a Sontaran stronghold.

Jelly babies

Jelly babies

Jelly babies are a confectionery favoured by a few versions of the Doctor. The Master is also seen eating jelly babies in the "The Sound of Drums".



An extremely valuable mineral. A small piece can power an entire fleet of battleships. One of the pieces of The Key to Time was disguised as a lump of Jethrik in The Ribos Operation.

A Journal of Impossible Things

The page from A Journal of Impossible Things.

A dream diary of sorts, containing notes and sketches by the Tenth Doctor's human persona, John Smith, in "Human Nature"/"The Family of Blood". The title is handwritten on the journal's first page. Referred to by Smith as "stories", it is shown on screen as scribbled words and what appear to be charcoal pencil sketches, recording what Smith remembers about his dreams of adventures as the Doctor, primarily those of the Ninth and Tenth Doctors. Joan Redfern retains the Journal at the end of "The Family of Blood", eventually publishing it in 2009 during The End of Time.

One two page spread contains illustrations of all ten Doctors to date, as seen on a flash animation on the BBC web site at the time of "The Family of Blood" air date. The drawings seen on screen in "Human Nature" are of the First, Fifth, Sixth, Seventh, and Eighth Doctors, the first time each has been depicted in the revived series.[2] The Journal also features sketches of the TARDIS interior and exterior, a sonic screwdriver, the Torchwood Institute logo, K-9, Rose Tyler, Autons, Clockwork androids, Cybermen, Daleks, the Moxx of Balhoon, gas-mask zombies from "The Empty Child"/"The Doctor Dances", and the Slitheen.

Repeated phrases describing key concepts (such as 'magic box', referring to a picture of the TARDIS) abound in the handwritten text, along with many misspellings. One repeated phrase, 'bigger inside than outside', also appears in Latin as: 'Maius Intra Qua Extra'. The Journal prop itself was created by artist Kellyanne Walker, and incorporates text provided by writer Paul Cornell.[3]


Key of Rassilon

A Gallifreyan artefact that allows access to the Matrix, the repository of all Time Lord knowledge. It is kept by the Keeper of the Matrix, and should not be confused with the Great Key of Rassilon or the Rod of Rassilon.

Key to Time

Koh-i-Noor Diamond

Revealed to be an element for a telescopic device designed to focus a beam of moonlight to trap and eventually destroy the physical form of a werewolf in "Tooth and Claw".


Laser Screwdriver

The Master's Laser Screwdriver

A weapon used by the Master in "The Sound of Drums" which resembles the Doctor's sonic screwdriver. It can kill with a directed laser beam or artificially age a target (provided the device has a blueprint of the victim's biological data) using a smaller version of the Hypersonic Sound Wave Manipulator technology designed by Professor Richard Lazarus. It is built with isomorphic controls, preventing anyone but the Master from using it. A toy version has been produced to go alongside the toy Sonic Screwdriver. Removed from the Master by the Doctor using telekinesis and not seen again.

Laser spanner

A device which was owned by the Doctor until it was stolen by Emmeline Pankhurst, whom the Doctor referred to as a "cheeky woman". Martha Jones initially believed she had coined the term as a joke upon being introduced to the sonic screwdriver.



These clamps negate the weight of the things they are attached to, allowing a single person to easily lift something weighing several tons. Those seen belong to the Torchwood Institute. It appeared in "Army of Ghosts" and "Doomsday". In "Doomsday", the Tenth Doctor and Rose each use these clamps to attach themselves to the walls of Torchwood One to prevent themselves from being sucked into the Void along with the Dalek and Cyberman armies.


Mechanical/Clockwork Mouse

In The Doctor's Daughter, the Tenth Doctor takes a grey clockwork mouse from his pocket and uses it to distract a guard.


In The Keeper of Traken, Melkurs are evil beings turned into statues when they arrive on the planet Traken. The statue featured in the serial is revealed to be The Master's TARDIS.

Mercury Fluid Links

In The Daleks, the First Doctor claims tubes filled with mercury are required to make the TARDIS work. The fluid links malfunction again in The Wheel in Space, this time producing toxic mercury vapour.

Mergin nut

A device from the Doctor's toolbox that he requests from Sarah Jane Smith at the end of "The Hand of Fear."


From the Third Doctor serial Carnival of Monsters. Its use as a peep show containing various creatures is outlawed, but the Doctor found an active one in the hands of the Lurman entertainers Vorg and Shirna on the planter Inter Minor. Their miniscope included Drashigs, Cybermen, and humans on board a ship.

Molecular disseminator

An experimental means of interstellar teleportation accidentally used to send the First Doctor and his companions from Earth to Kembel in The Daleks' Master Plan.




Nanotechnological robots which can heal damaged tissue. They are Chula technology, seen in "The Empty Child" and "The Doctor Dances". The nanogenes are designed to heal soldiers and ready them for battle, making them Om-com capable.


An explosive substance created and used by the Seventh Doctor's companion Ace, often carried around in her backpack in aerosol spray cans, despite the Doctor's warnings.

Nova Device

The Movellans failed to destroy the Daleks' homeworld of Skaro with this device in the serial Destiny of the Daleks.



A communications system used by Jack Harkness and the revived Jamie in "The Empty Child"/"The Doctor Dances". It allows anyone to communicate with anything that possesses a speaker grille, even if the device being used is inoperable, or not even capable for such a function (such as phone in TARDIS or a talking toy).

Opera Glasses

These are a small set of binoculars that the Doctor carries with him in the 2005 episode "The Empty Child", as well as in the novel The Nightmare of Black Island. In the latter, he uses them to gain a closer view of Ynis Du's lighthouse. The actual origin of the glasses are unknown; however, the fact that they are described as having "computer-enhanced lenses" suggests that they are a product of some future time.

Osterhagen key

The Osterhagen (an anagram of "Earth's Gone") Key is a priming device controlled by UNIT for a series of 25 nuclear warheads placed beneath the Earth's crust at strategic points, for use at a time when Earth's destruction is preferable to the alternative. Osterhagan stations are located in various countries, including Argentina, China, Germany and Liberia. To be activated, at least three Osterhagen bases must be online. The Key was given to Martha Jones by UNIT in "Journey's End", but was lost when she was brought by transmat on board the Dalek Crucible. Martha explained that the Osterhagen Key was to be used "if the suffering of the human race was so great, so without hope, then it became the final option". The Doctor requested that Martha get rid of the Osterhagen system.


Paradox Machine

The Paradox Machine

Designed by the Master in "The Sound of Drums", the device is constructed from the Doctor's TARDIS, centred around the main console with several large pipes leading into it, installed on the airborne aircraft carrier Valiant. The paradox machine uses the power of the TARDIS to prevent the universe from collapsing under the inherent logical contradiction of a grandfather paradox when the Toclafane kill their ancestors, modern day humans. When destroyed, it has the effect of reversing time up to the point immediately before it was originally activated. However, those in proximity to the device are immune to this effect by virtue of being in the "eye of the storm", the radius of which is at least sufficient to encompass the Valiant. The paradox machine was destroyed by Jack Harkness who shot at it with a machine gun.

Perception filter

A perception filter is a field generated by a TARDIS that convinces people to ignore it, which in the case of the Doctor's TARDIS makes the normally anachronistic police box seem perfectly ordinary wherever it lands, no matter how out of place it may be. The field extends to objects associated with the TARDIS, such as the keys used to open it. Perception filters can also be added to other objects, such as the fob watches used by the Doctor and the Master. The TARDIS also imparts a perception filter to a stone slab near a fountain in Cardiff during the events of "Boom Town", which Torchwood Three has attached to an elevator. The field does not work if the object it surrounds draws too much attention to itself, or if someone is specifically searching for the object in question. Those with even minor telepathic abilities are also immune. In "Last of the Time Lords" Martha Jones uses the one installed on her TARDIS Key to protect her from the Master's detection during the year he ruled the world. It would appear that those who have previously seen the TARDIS are not affected by the Perception filter, such as Sarah Jane Smith when she discovers it in School Reunion

The concept is similar to the Somebody Else's Problem field in Douglas Adams's novel, Life, the Universe and Everything.

Preacher Gun (Mk II)

A large energy gun, capable of causing a Dalek to explode. They were used by Jackie, Mickey and Rose in "The Stolen Earth" and "Journey's End". They are likely to be an upgrade of the guns used by the Preachers in "Army of Ghosts"/"Doomsday", which were unable to destroy a Dalek even when modified by the Doctor with the sonic screwdriver.

President's Gauntlet

President's Gauntlet

A metal glove used by the Lord President of Gallifrey in "The End of Time". It is used to disintegrate a female Time Lord when she goes against the wishes of the Lord President, and to revert the Master's actions, restoring the human race to normal.

Progenation Machine

A progenation machine is a device in "The Doctor's Daughter" that artificially produces a direct descendant of a donor. By taking a sample of the subject's diploid cells, it can split the cells into haploids and rearrange them in a new configuration. The new DNA is then used to grow an adult subject within moments. The subject emerges fully-clothed, and the machine can download knowledge directly into their brain, which in the episode is used to create trained soldiers en-masse. It is through this process that Jenny, the Doctor's titular daughter, is created.

Psychic credit card

This item was used in the BBC novel Only Human to open a bank account of half a million pounds sterling in balance for Jack Harkness and the Neanderthal named Das. According to Captain Jack in the novel, the psychic credit card was banned after the Infinite Recession of Bayfadarn.

Psychic paper

Described as "slightly psychic" paper and first appearing in the 2005 series episode "The End of the World", psychic paper is an apparently blank prop kept in a credit card or travel pass holder. It allows those holding it to show people whatever they want to see on the card. The paper has shown the ability to display telepathic messages from sources external to the user (such as the Face of Boe in "New Earth") and can apparently unlock electronic pass readers ("Army of Ghosts") and record transit fares ("Planet of the Dead"). Torchwood Institute personnel receive psychic training and are not susceptible to psychic paper. It apparently does not work on those of very high intelligence, either, as William Shakespeare was shown the paper in "The Shakespeare Code" and commented that it was blank, which the Doctor notes proves Shakespeare is a genius. In the Doctor Who Magazine comic strip "The First", Ernest Shackleton also sees the paper as blank, comparing it with an attempt to hypnotise him which had been equally ineffective.

In the Past Doctor Adventures novel World Game, it is said to be a then-recent invention of the Celestial Intervention Agency; if this is the case, then from 2005 series episode "The End of the World" it can be considered as one of the few Time Lord artifacts remaining (besides the TARDIS).

The use of psychic paper and the results obtained seem to vary somewhat. In "The Empty Child", Jack Harkness states that it is a "tricky thing" and Rose says that you "can't let your mind wander when you're handing it over." Both he and Rose inadvertently give away private details about themselves when passing it between them. In "Tooth and Claw", the Doctor seems surprised when Queen Victoria says "It states clearly here that you have been appointed by the Lord Provost as my Protector." Later on, in "The Idiot's Lantern", the Doctor flashes the paper at a guard, and then has to look at it in order to tell Tommy that the man thinks he's the King of Belgium. This is also shown in the New Series Adventures novel The Nightmare of Black Island, in which the Doctor is unsure what another character saw, as there is no 'after-image'. In contrast, at its introduction in "The End of the World", the Ninth Doctor shows it to the steward while simultaneously stating what he wanted it to show. The steward's response of "Well, obviously...," gives the impression that when the person handing it over specifies what it should say, it does. The Tenth Doctor actually uses both methods in "Tooth and Claw", giving specifics to the Guard Captain, but letting Queen Victoria see what she needed.

Psychic paper has also been shown to be able to receive messages from throughout the universe, this was first shown in New Earth, when the Face of Boe sends the Doctor a message, and again in Silence in the Library, where the Doctor receives a cry for help from Professor River Song.


Quantum Accelerator

A TARDIS component, one of the items exchanged between the Master and the Doctor in Time-Flight.

Quantum Crystaliser

A device featured in the audio drama Human Resources used by the Celestial Intervention Agency to control time over a small area. It uses branching timelines to explore various possible futures and select the one it likes. Exposure to two Crystallisers causes dangerous instability, potentially leading to death.



The Fourth Doctor fitted this device to the TARDIS console in The Armageddon Factor to randomise his travel coordinates and prevent the Black Guardian from finding him. The Randomiser was removed from the TARDIS and left on the planet Argolis in The Leisure Hive. A similar process is seen in The Price of Paradise, in which the Doctor uses the random shuffle function on Rose's MP3 player to select the TARDIS's destination, and the Doctor is able to "set all the settings to random" in the 2008 episode "Planet of the Ood". The Eighth Doctor also fits a randomiser to his companion Compassion in The Fall of Yquatine to stop her being traced by the Time Lords.

Record of Rassilon

An accounting of a war fought between a Vampire race and the Time Lords. It is found on most Type-40 TARDISes. The Record consists of punchchards which when inserted into the TARDIS console will print out whatever was on the card. In the episode "State of Decay" the Fourth Doctor uses this Record to find out information about the war, the Vampire's weaknesses, and an edict by Rassilon that any Time Lord that finds one of the Vampires should put them to death immediately.

Reality Bomb

The Reality Bomb

A device created by Davros and the Daleks which they prepared to use in "Journey's End". It was meant to disrupt the electrical bond between all atoms in every form of matter, using Z-neutrino energy compressed into a single string by an alignment of 27 planets, therefore destroying the whole of the universe and all other universes via a rift at the heart of the Medusa Cascade. It was, however, disabled by Donna.


The Second Doctor was often seen playing a recorder. It played a pivotal role in the serial The Three Doctors as well as often being used by the Second Doctor to distract and confuse his enemies.

Rod of Rassilon

Another name for the Great Key, not to be confused with the Key of Rassilon or the other Great Key. It is a control device for the Eye of Harmony, and can be used to drain power from it.


Sash of Rassilon

A control device for the Eye of Harmony, it is used to protect the wearer from the Eye's gravitational and energy forces.


The Fourth Doctor's long, multicolour-striped scarf, which he claimed was knitted for him by Madame Nostradamus (described by the Doctor as "a witty little knitter"), is one of the images people generally associate with the character. He had more than one in similar designs and during the time he travelled with Romana, he could be seen wearing one while another was hanging on the Console Room hatstand. The scarf the Doctor wore during his regeneration at the end of Logopolis was unravelled by the Fifth Doctor in the beginning of Castrovalva. A Fourth Doctor-style scarf was seen hanging in the TARDIS Wardrobe Room in the Tenth Doctor special "The Christmas Invasion". The Seventh Doctor wore a smaller paisley scarf. Romana wore a white version of the scarf during Destiny of the Daleks.

Seal of the High Council

A round metallic object emblazoned with the Seal of Rassilon, this symbol of Time Lord authority was given to the Master in "The Five Doctors" to prove to the Doctor that he was working with the Time Lords and not against them. The Third Doctor believes that the Master has stolen it from the Time Lords and takes it from him. When the Master tries to explain to the Fifth Doctor that one of his other selves has taken it he does not believe him.

Seal of Rassilon

A spiralling insignia somewhat reminiscent of a Celtic knot, it serves as a logo of the Time Lords. It is seen in multiple episodes of the series to designate the Time Lords and Gallifrey. The Seal is most often seen on Time Lord architecture and artifacts, as well as badges on ceremonial clothing. The Seal was featured heavily in the interior design of the Eighth Doctor's TARDIS. It was seen most recently in "The Sound of Drums", set in stonework beneath the Untempered Schism.

Security disk

In the 2007 episode "Blink" the Doctor retrieves his TARDIS after losing it by means of a security disk. This was essentially a DVD with specific code compatible to the TARDIS. He entrusts the DVD to Sally Sparrow, who inserts the disk into the TARDIS console, causing it to dematerialise, leaving her and Larry Nightingale behind. The security disk is valid for one journey. The TARDIS seems to automatically detect these disks and generates an accompanying hologram of the Doctor to announce this detection as a result.

The Tenth Doctor's severed hand

Severed hand

See also: List of Torchwood items#Severed hand

The Tenth Doctor's severed right hand in a transparent case filled with a preservative liquid. The hand was severed by a Sycorax sword during their invasion of Earth ("The Christmas Invasion"). The Doctor regrew the hand due to the healing after-effects of his very recent regeneration. Captain Jack Harkness retrieved the hand and stored it.[4] He is very protective of the hand, saying that it means something only to him. It is seen to glow as the sound of the TARDIS engines approaches, much like the TARDIS key ("End of Days"). It is next seen in "Utopia", where Jack describes it as a "Doctor detector." At the end of that episode the hand is stolen by the Master, along with the Doctor's TARDIS. In "The Sound of Drums", the Master reveals he has used it to derive the Doctor's biological code, with which he accelerates the Doctor's aging by one hundred years wielding the laser screwdriver. Following the events of "Last of the Time Lords", the Doctor recovers and keeps the hand. The hand is later seen at the end of 2008 episode The Poison Sky where it seems to glow and bubble as it did in Torchwood episode ("End of Days"). This is indirectly explained in the following episode, "The Doctor's Daughter", as it sensing the appearance of the Doctor's genetic material, in the form of Jenny, in another timezone. At the end of the episode "The Stolen Earth", the Doctor is shot by a Dalek and is forced to regenerate, but in the following episode, the Doctor transfers the regeneration energy from him into the hand. This allows him to heal his wounds but still keep the same form. Later Donna touches the hand filled with regeneration energy which causes the hand to regenerate into a half human, half Time Lord copy of the Doctor but also has the side effect of giving Donna all the knowledge of a Time Lord. At the end of the episode the Doctor copy travels into the alternate universe and stays with Rose.


Dimensionally transcendent time machines named SIDRATs were provided by the War Chief to the alien race known as the War Lords in The War Games. According to the novelisation of the story by Malcolm Hulke, SIDRAT is an acronym for Space and Inter-Dimensional Robot All-purpose Transporter, as well as the backwards spelling of TARDIS.


The name given to a 'suit' made from victims of the Slitheen. It is made by hollowing out a victim's body and placing a zip on the forehead, and with the aid of a compression field the Slitheen then use it as a disguise. Disguised Slitheen can also perfectly replicate the voice of the person they are disguised as, even when not wearing the skinsuit (although tinges of the alien voice are thrown in when not wearing it), although it is not made clear how this works. As the Slitheen are very large, up to eight feet in height, and the compression field only has a limited ability the skinsuits tend to be made from already large people. According to the book The Monsters Inside, the events of which are referenced in the episode "Boom Town", Raxacoricofallapatorians in the far future have perfected the technology so they can fit into skinsuits far smaller than they are. This is also shown in the Sarah Jane Adventures story "The Lost Boy".

Sonic blaster

Featured in "The Doctor Dances", the sonic blaster, also known as a "squareness gun", is a handheld weapon from the 51st century, produced in the weapon factories of Villengard, that can disintegrate as well as reintegrate its targets. The latter function quickly runs down its batteries when used repeatedly. The one featured is owned by Captain Jack. It fires in a peculiar square shape rather than the more traditional round pattern of most science fiction weapons. The factory that produced the blasters was destroyed, which the Ninth Doctor implies responsibility for; he claims to have visited it just once, and that there is now a nice banana grove in its place. In "Silence in the Library", set in the 51st century, Professor River Song possesses a weapon which acts in the exact same manner, and author of both stories Steven Moffat says it was the same item, left in the TARDIS by Captain Jack and taken by River during her time with the Doctor, a time which is actually in the future of the Doctor's personal timeline.[5]

Sonic knife

A tool used by Scaroth in stealing the Mona Lisa in City of Death.

Sonic lance

A handheld tool used by the Sixth Doctor in Attack of the Cybermen. It was used as a detonator to explode an unstable material which resulted in the destruction of the Cyberman base on Telos. A different sonic lance was seen in an earlier serial, Robot as an add-on to the sonic screwdriver.

Sonic pen

Wielded by Miss Foster in "Partners in Crime", the sonic pen has a similar range of functions to the sonic screwdriver, but was described as "sleek" in comparison. It looks like a normal black and silver pen with a blue light at the top, similar to the sonic screwdriver. It has the ability to open a 'triple-deadlocked' door, but whether this refers to all deadlocked doors, or just doors with deadlocks created by Miss Foster, the original owner of the pen, is unknown. The pen was last seen thrown in a bin by the Doctor.

Gwen Cooper is seen using a similar pen (complete with "sonic" sound effects and blue light at top) throughout Torchwood's third season. The full range of this pen's abilities is also unknown. After introducing it to Clement Macdonald while visiting him at a psychiatric clinic, she named it as a "Gizmo". It is primarily used on-screen to disable video cameras.

Sonic screwdriver

Space-time telegraph

A device given by the Doctor to Brigadier Lethbridge-Stewart that can contact the Doctor throughout time and space. It was supposed to be used only in the gravest of emergencies. The Doctor received its signal at the end of Revenge of the Cybermen, leading to the events of Terror of the Zygons. This is now obsolete, as in "The Sontaran Stratagem" Martha Jones's Superphone was used instead.

Sphere (Shada)

A device used as a weapon by Skagra in Shada. It was capable of removing a person's mind from their body, as well spreading the singular mind that Skagra wished to cover the entire universe with.

Sphere (The Abominable Snowmen & The Web of Fear)

Silver spheres which contain the consciousness of each Yeti.

Squareness Gun

As coined by Rose Tyler, this gun is a sonic device used to create square holes in walls, then the same hole can be sealed up using the reverse settings. First seen in The Doctor Dances, in the possession of Jack Harkness, it was most recently seen in Silence in the Library and Forest of the Dead, when the Doctor and Professor River Song's remaining team use it to try and escape the Vashta Nerada which had started to invade their spacesuits.

Stattenheim remote control

A device used by the Rani to control her TARDIS remotely. The Second Doctor also had a Stattenheim in the serial The Two Doctors, to the envy of the Sixth Doctor. The Doctor has also used the Stattenheim control in the spin-off media. The novels Christmas on a Rational Planet and The Quantum Archangel claim that Stattenheim was a human scientist from sixteenth century Berlin who, with his associate Waldorf, developed a working theory of TARDIS configuration.


The "Superphone" is an upgraded mobile phone that can make calls across time and space. It even calibrates to the user's home time period, as shown by Adam Mitchell's ability to call his home time on Rose Tyler's phone ("The Long Game"), despite their native time periods being about six years apart. In addition, it can send signals in places ordinary phones cannot, such as the sealed Cabinet Rooms at 10 Downing Street ("World War Three"). However, its range is not infinite ("The Impossible Planet"). The Doctor describes the Superphone as being able to "...Call anyone, in any time, so long as you know the area code."

The superphone first appears in "The End of the World", where the Ninth Doctor modifies Rose's Nokia 3200 mobile phone with a special device that goes in place of the battery. In "Rise of the Cybermen", the Nokia 3200 is replaced by a Samsung D500, but otherwise seems to function the same. A Samsung D500 is also seen used by Tish Jones in The Sound of Drums. It is also able to link up with the Cybus Industries Ear-Pod network. Rose gives the phone to Mickey Smith at the end of "The Age of Steel", but replaces it soon after.

After Martha Jones becomes an ongoing companion to the Tenth Doctor in "42", he gives her phone, the BenQ-Siemens EF81 a similar upgrade. This phone, however, is upgraded by the Doctor's sonic screwdriver, and the feature itself is referred to as "Universal Roaming". Martha's phone has the Archangel network logo on its display, the significance of which is revealed in "The Sound of Drums". At the end of the episode "Last of the Time Lords", Martha gives her phone to the Doctor, so she can contact him if trouble occurs. The Doctor uses the same process to upgrade Donna Noble's phone in "The Doctor's Daughter", but it is only used once onscreen to contact Martha's similarly upgraded phone. When his allies try contact the Doctor in "The Stolen Earth" by means of Martha's superphone now in his possession, the number displayed onscreen is 07700 900461. After the airing of this episode, 2500 fans tried dialing the number.[6] In "Journey's End", Wilfred mentions that he has received a phone call from Donna, presumably by means of her Superphone.

In "Planet of the Dead", the Doctor uses the sonic screwdriver to create a superphone to contact, and be contacted by, Malcolm Taylor, who is the other side of the wormhole. The phone is of the Nokia Prism series.




A TARDIS (Time And Relative Dimensions In Space) is a spaceship invented by the Time Lords that can travel through space and time. The Doctor travels in a Type 40 TARDIS. A TARDIS can travel to any time and place in the universe, except to events that are Time-Locked, such as the Time War. In The Next Doctor, Jackson Lake made a typical hot-air balloon, which he called his TARDIS (Tethered Air Release Developed In Style).

TARDIS comparator

A TARDIS component, in Planet of Fire, Kamelion removes it from the TARDIS and gives it to Peri Brown so that the Master cannot use it.

TARDIS shields

According to the Fifth Doctor in "Time Crash", the Tenth Doctor failed to turn the shields on after "repairing the TARDIS". Thus causes two TARDISes to combine and the Titanic to crash into the TARDIS.

Temporal Limiter

A TARDIS component, one of the items exchanged between the Master and the Doctor in Time-Flight.

Terraforming device

A round glass container made in a laboratory that holds gases and liquids designed specifically for making a barren planet habitable. Even when the device is in a transit state vegetation grows in the area surrounding it. Used in "The Doctor's Daughter" to make the planet Messaline habitable.

Time Cabinet

A primitive time machine used by Magnus Greel in The Talons of Weng-Chiang which is deadly to the user.

Time Destructor

Powered by a core of taranium, the rarest element in the Universe, and able to accelerate the flow of time, the Daleks hoped to gain control of the Solar System with this device in The Daleks' Master Plan.

Time Log

In The Keeper of Traken the Doctor is noted to have once kept Time Logs. These were records of journeys made in the TARDIS and he used the Time Logs to attempt to refresh his memory of visiting the planet Traken. Eventually, the Doctor ceased keeping Time Logs on account of the fact of having better things to do; although River Song's book may be a continuation of the Time Log.

Time Ring

Given to the Fourth Doctor in the serial Genesis of the Daleks by the Time Lords so that he could escape Skaro on successful completion of his mission to avert the creation of the Daleks. The Doctor, Harry Sullivan, and Sarah Jane Smith use the Time Ring at the end of the adventure and are taken to the Nerva station where they go on to participate in the events of Revenge of the Cybermen. Another Time Ring makes an appearance at the end of the Tenth Doctor novel I am a Dalek. Bernice Summerfield and Jason Kane were also given time rings as a wedding present by the Seventh Doctor in the Virgin New Adventures spin-off novel Happy Endings by Paul Cornell. These were used (and destroyed) by Peter Summerfield in the Big Finish Productions audio adventure The Grel Escape. The Eighth Doctor was also given a Time Ring by a rather smug Time Lord by the name of Straxus to go back and rescue Lucie Miller in the audio drama Human Resources.

Time scoop

The Time Scoop was a primitive 'Time Corridor' technology created on Gallifrey during the Dark Time, similar in sophistication to Dalek time-travel technology. Its purpose was to remotely 'scoop' individuals from their own time period and deposited them within the Death Zone, a securely controlled environment on Gallifrey. Those kidnapped were then expected to compete in gladiatorial games. In "The Five Doctors", the Scoop was used to fetch various incarnations of the Doctor and his companions to the Death Zone, along with various foes such as the Daleks, Cybermen, and Yeti. The Time Scoop plays a minor role in the Eighth Doctor Adventures novel The Eight Doctors, and a major role in the final chapter of the Gallifrey audio series.

Time/Space Visualiser

A device given to the First Doctor at the end of The Space Museum, it is a "time television", allowing the operator to tune in on any event in history. The TARDIS crew used it to watch various historical events at the beginning of The Chase.


A doorway that exiles a person pushed into it down a corridor of Time and Space. Used in the episode of the same name.

"Timey-wimey" detector

Timey-Wimey Detector

A detector of temporal disturbances constructed by the Tenth Doctor in "Blink" when he and Martha Jones are sent back to 1969 without the TARDIS by the Weeping Angels. The unserious sounding name appears to be the Doctor's joking reference to his own inability to describe temporal theory in succinct layman's terms; he describes its operation as "Goes ding when there's stuff." He also says it can boil eggs at thirty paces, whether the user wants it to or not, and that he has therefore learned to avoid hens. Visible elements of the device's construction include a lunchbox, a telephone handset, some tape reels, a postcard, and the Doctor's sonic screwdriver.

Tissue Compression Eliminator

The Master's weapon of choice, it shrinks people to doll size, killing them in the process. He no longer used it by the time of Survival. The weapon was also used by the Doctor to shrink the alien mechanoid Death's Head in his Marvel Comics adventures. This was parodied in the Radio 4 comedy series Nebulous, in which the arch-enemy of Professor Nebulous, Doctor Klench, miniaturises his foes, but unlike the Master's victims, they are not dead and Klench carries them around with him.

TOMTIT machine

Ostensibly a teleportation device, seen in the Third Doctor serial The Time Monster. The acronym stands for Transmission Of Matter Through Interstitial Time.


A device which disperses matter, transmits it to and then reconstitutes it in another location. Transmats are used in the serials The Seeds of Death, The Ark in Space, Revenge of the Cybermen, The Armageddon Factor, The Five Doctors, Mawdryn Undead, The Twin Dilemma, Remembrance of the Daleks, "Bad Wolf", and "Journey's End", among others. The word "transmat" is also used as a verb.

Travel dial

In The Keys of Marinus, devices that could teleport the user from one place to another (similar in appearance to a wristwatch).

Tribophysical waveform macro-kinetic extrapolator

An interstellar transportation platform that utilises massive energy to create a force bubble that protects the rider while riding the shockwave to its destination — in short, a "pan-dimensional surfboard". It was introduced in "Boom Town" and thereafter used to create a force field, first around the TARDIS and later the Game Station, in "The Parting of the Ways". It was also used in "The Runaway Bride" to shunt the TARDIS two hundred yards when it was forcibly summoned by the Empress of the Racnoss. In this latest appearance, the Extrapolator is partly covered by a coral-like crust similar to that found in the console room's construction, indicating that the TARDIS has somehow begun to absorb it into its systems. It is unknown where the extrapolator came from originally, though Margaret Blaine (the Slitheen) comments it 'fell into her hands', Jack Harkness claims it was way beyond her to build it. Though he later suggests she stole it in a major heist, Blaine makes no confirmation to this theory.

Trilogic game

A devious game designed by the Celestial Toymaker in the story of the same name — it is essentially the Tower of Hanoi.


An ore used primarily in computers and as spaceship fuel. Originally mined on Mars (as seen in The Curse of Peladon), it was later found on Peladon (The Monster of Peladon). It occurs in abundance on Laylora, as described in the novel The Price of Paradise.



The Seventh Doctor carried, from Delta and the Bannermen onwards, an umbrella with a question-mark shaped handle. He had ceased using it by the time of his last appearance in the Doctor Who television movie. The Sixth Doctor occasionally carried a different umbrella, a multicolored model with a straight handle. This was destroyed in the Seventh Doctor's first story, Time and the Rani. The first time the Doctor is seen on screen with an umbrella (a simple black one), is in the Second Doctor serial The Krotons.

Universal Roaming

See superphone.

Untempered Schism

A gap in the fabric of reality, the Untempered Schism allows one to look directly into the Time Vortex. It is depicted as a stonework portal through which one sees the Time Vortex unaided. Gallifreyan children are taken to the Schism at the age of eight and made to face the Schism as a form of initiation into the Time Lord Academy. According to Tenth Doctor, Gallifreyan children who look into the time vortex through the Untempered Schism were either inspired, ran away, or went mad. In a flashback during "The Sound of Drums", the Master is seen looking into the Schism as a child, an event that Tenth Doctor describes as the moment the Master went mad. The Doctor says he himself was one of those who "ran away, and never stopped".



A living metal created on Gallifrey that has the power of life and death. It appears in the serial Silver Nemesis.


Seen in "The Idiot's Lantern". Using parts obtained from a 50's electrical shop the Doctor constructed a working video cassette recorder. He used it to foil the Wire by using it as a receiver, sucking in the villain and trapping her in a Betamax videotape. He assures Rose that he will destroy the Wire by recording over it.

Void ship

A vessel capable of travelling in the void, the area between dimensions outside of time and space. The Doctor expresses surprise at encountering one, saying, "I thought it was just a theory," and so such technology was presumably beyond the Time Lords. However, the Cult of Skaro—a secret order of Daleks—manage to obtain one, and thus survive the Time War with the Time Lord prison ship referred to as the Genesis Ark.

Vortex magnetron

A device used by Daleks in Day of the Daleks which could draw time travellers to a certain location.

Vortex manipulator

A more primitive form of time-travel technology, a vortex manipulator allows the user to travel through time by minimally controllable (and apparently uncomfortable) "hops" through the Time Vortex. The technology is compact enough to be worn on one's person easily, such as the wrist-mounted device in the possession of Jack Harkness, which he obtained during his stint as a Time Agent. The Family of Blood also had one capable of moving a small spaceship. When Jack notes that such technology means the Doctor is not the only person capable of travelling through time, the Doctor disdainfully compares the "space hopper" vortex manipulator to his "sports car" TARDIS. The device also allows travel through space by harnessing the energies of wormholes (such as the Cardiff Rift), as demonstrated by Captain John Hart and Gray in series 2 of Torchwood. As seen in "The Sound of Drums", the Manipulator can also be programmed to teleport its operator (and anyone hanging on) from place to place once the Doctor has used his sonic screwdriver to jump-start it. The Doctor disables Jack's manipulator at the end of "Last of the Time Lords", but Jack figures out how to re-enable it (or at least restore its teleport function) in "The Stolen Earth". In the last episode of the 2008 series "Journey's End" the Doctor once again disables Jack's vortex manipulator with his sonic screwdriver. In the final episode of "Children of Earth", it is revealed that the Vortex Manipulator (or at least Jack's) is indestructible, capable of surviving an explosion that destroyed the Torchwood Three building.



A small crystalline device carried by Sarah Jane Smith in "Journey's End" that looks like a necklace, but is in fact a highly explosive device (a "Warp-fold conjugation") inside a carbonised shell. According to Sarah Jane, it was given to her by a Verran soothsayer to be used at "the end of days". Jack Harkness wires it into the Dalek Crucible's mainframe and threatens to use it; however, he does not get the opportunity as the Daleks swiftly transmat Jack, Sarah Jane, and their companions away.


The Doctor sometimes carries a watch, either a wristwatch or a pocket watch. In Silver Nemesis the Seventh Doctor's pocket watch has an alarm signalling planetary disaster and could also be used as a scanner (as seen in Survival). The Sixth Doctor and Ninth Doctor's watches could also indicate the era he was in (The Mysterious Planet, "The Long Game").

White Point Star

A White Point star is a perfect uncut diamond found only on Gallifrey and is used by Lord President in "The End Of Time" to bridge the gap between the end of the Time War and present day Earth. The Master uses this to summon the remaining Time Lords from the Time War. The Doctor then destroys it by shooting it with Wilfred Mott's gun.

Wormhole Refractor

A device the Doctor mentions as useful for crossing the universe in the 2006 series episode "Fear Her".

Worshipful and Ancient Law of Gallifrey, The

An ancient book from Gallifrey, seen in Shada. It was created by Rassilon, but later stolen by Professor Chronotis. Time runs backwards over the book. It has the power to grant access to the planet Shada. In various spin off media, it is shown to be able to erase a parallel universe and trap an entity.




Zero Cabinet

A cabinet made from the remnants of The Zero Room which was a room in the TARDIS. The room had walls that shielded it from the rest of the universe, providing a restful environment for the Fifth Doctor to recover from his regeneration in Castrovalva. When the room is later jettisoned in an emergency, its doors are made into the "Zero Cabinet", a coffin-sized box with the same shielding properties. In the Big Finish audio "Zagreus", the TARDIS is able to create a potion of "Zero Matter" which has similar properties.

Zeus Plugs

At the end of Fourth Doctor serial "The Hand of Fear", the Doctor asks Sarah Jane Smith for a zeus plug to help him repair the TARDIS thermocouples. He then changes his mind and uses the sonic screwdriver instead. They are also mentioned in "The Girl in the Fireplace". While their function is unknown, the Doctor said he had earlier been using them as castanets while at a party with Madame de Pompadour in 18th century Paris.
