K-9 is the designation given to a series of intelligent dog-like robots who have served as companions for the Doctor, Leela, Romana and Sarah Jane Smith. The robots' name is often presented as K9 with no hyphen (The Adventures of K9).




K-9 Mark I

"Ready, master."
―K-9 to the Doctor

Professor Marius, who invented the first K-9, describes him as "My best friend and constant companion." Marius used to have a dog on Earth but because weight requirements did not allow him to bring his real dog from Earth into space so he created K-9. (DW: The Invisible Enemy) However, K-9 may owe his existence to a temporal paradox. According to one account, the Professor copied the remnants of one of the version of K-9 created by the Doctor and given to Sarah Jane Smith. (DWM: Tautology)

The Professor offered K-9 to the Doctor as the same weight requirements made him unable to take Mark I back to Earth with him. (DW: The Invisible Enemy) After a number of adventures with Leela and the Doctor, Mark I decided to stay on Gallifrey with his "mistress". (DW: The Invasion of Time).

K-9 playing chess against the Fourth Doctor. (DW: The Sun Makers)

The Fourth Doctor and K-9 Mark II spent an indeterminate period of time together. However, in the next episode, DW: The Ribos Operation, the Doctor appeared to be activating K-9 Mark II, giving the implication only that no significant time had elapsed since leaving Gallifrey.

There are (possibly apocryphal) accounts that this model of K-9 later performed missions on behalf of the Time Lords and was given control of a space vessel called K-NEL (The Adventures of K9: K9 and the Time Trap, et al).

At one stage, he chased two Jixen to 2050 Earth and self-destructed. (K9TV: Regeneration)

K-9 Mark II

"Optimism: belief that everything will work out well. Irrational, bordering on insanity"
―K9 on optimism
K-9 with the Fourth Doctor and Romana. (DW: The Leisure Hive)

At some point prior to this, the Doctor obtained or constructed at least one (possibly more) backup models of K-9, and immediately after leaving Mark I behind with Leela, the Doctor unpacked K-9 Mark II. This version of K-9 accompanied the Doctor and new companion on their quest to locate the segments of the Key to Time (DW: The Ribos Operation), however the swampy terrain of Delta III made it impossible for him to accompany them there. At the conclusion of the quest, the Shadow turned K-9 to his evil will, during which time K-9 assumed a sinister personality. (DW: The Armageddon Factor)

The Doctor found that K-9 had contracted laryngitis and had lost his voice as a result of this. K-9 was left in the TARDIS while the Doctor and Romana battled the Daleks and Davros (DW: Destiny of the Daleks). During a subsequent adventure, it remained patiently in the TARDIS, which would imply that his voice had not yet returned. (DW: City of Death) After the return of his voice, it sounded quite different and remained so for a number of adventures (DW: The Creature from the Pit). However, later the familiar voice returned. (DW: The Leisure Hive)

Damaged by the time winds, K-9 Mark II could not cross back into N-Space with the Doctor, so decided to stay behind at the Gateway with Romana, to help her free the remaining Tharils from slavery. (DW: Warriors' Gate) Eventually, however, Romana and the presumably repaired K-9 returned to their own universe, and K-9 Mark II came to live on Gallifrey. (NA: Lungbarrow, WC: Shada)

The fates of K-9 in light of the Last Great Time War remain unknown.

K-9 Mark III

K-9 protecting the Doctor and the others. (DW: School Reunion)
"K-9! Rose Tyler, Mickey Smith, allow me to introduce K-9! Well, K-9 Mark III, to be precise."
―The Tenth Doctor introducing K-9 to Mickey and Rose

A third model, K-9 Mark III (again either obtained or constructed by the Doctor) was shipped to Sarah Jane Smith in 1978 to serve as her companion, but she did not receive his gift until 1981. Afterwards, K-9 assisted Sarah Jane in defeating the Hecate Cult of Moreton Harwood. (KAC: A Girl's Best Friend) Circa 1983, K-9 Mark III still lived with Sarah Jane, but, by chance, did not accompany her to Gallifrey. (DW: The Five Doctors) K-9 accompanied Sarah to an archaeological dig in Egypt. (DWM: City of Devils) In the early 1990s, K-9 assisted Sarah in investigating a supposedly haunted house. (VD: Housewarming)

In 1996, Sarah used K-9 to hack into records and find Sam Jones' home address, and later to translate Lost Boy's speech. (EDA: Interference - Book One) K-9 was briefly possessed by a malevolent entity, but was freed when Sarah accidentally electrocuted him. (ST: The Sow in Rut) K-9 began slowly breaking down and eventually ended up deactivated in a cardboard box in Sarah's attic. (VD: Moving On) Hilda Winters had K-9 dismantled and analysed. (BFSJS: Mirror, Signal, Manoeuvre)

Sarah, unable to find anyone to fix the robot, continued to carry K-9 in the boot of her car, until a chance encounter with the Doctor in the mid-2000s resulted in K-9 being restored to functionality. This served to be only temporary, however, as Mark III self-destructed in order to help the Doctor and his companions defeat a Krillitane invasion (DW: School Reunion).

K-9 Mark IV

K-9 communicating with Sarah Jane Smith via a subspace portal linked to 13 Bannerman Road. (SJA: Invasion of the Bane)
"There was a scientific experiment in Switzerland, they created their own black hole. If it gets free the Earth will be swallowed up. So K-9 is sealing it off."
Sarah Jane Smith

After Mark III sacrificed himself to defeat the Krillitanes, the Doctor left a new model, Mark IV, for Sarah Jane Smith, just seconds after he departed in his TARDIS (It's not known if the Doctor quickly built Mark IV from scratch or had it in storage). K-9 refers to himself as being rebuilt and improved, suggesting Mark IV possesses the same memory as Mark III. (DW: School Reunion) Though Sarah Jane didn't find this out right away, the Doctor had also placed some gifts in a panel in K-9's side: sonic lipstick and a Scanner Watch that could detect alien life.

A year before Sarah Jane first met Maria Jackson, K-9 Mark IV left Sarah Jane in order to stabilise a dangerous artificial black hole in space which had been created in Switzerland. He could only speak with Sarah Jane occasionally via a cabinet with a spacetime link when the orbit of the black hole intersected with that of Earth and did not know when he would complete the job. (SJA: Invasion of the Bane) However, at times he was capable of returning to Earth very briefly during emergencies, and did so on two later occasions in order to render vital assistance. In the first time, he fought Mr Smith in pitched battle to allow Sarah Jane to upload the Armaggedon Virus, (SJA: The Lost Boy) and again in order to quickly upload TARDIS base codes to Mr Smith and assist the Doctor in returning the Earth to its correct location in space. (DW: Journey's End)

After these events he went back monitoring the black hole only to find an unidentified member of the Slitheen family attempting to steal him as part of a revenge plot against Sarah Jane who had foiled their plans in the past. K-9 banished the Slitheen, after reversing one of its attacks.(SJA: From Raxacoricofallapatorius With Love)

K-9 was eventually able to return when Ship used the black hole as fuel. Though Sarah Jane, Luke, Rani and Clyde were happy to have K-9 back, Mr Smith was not. (SJA: The Mad Woman in the Attic) He then spent a lot of his time in Sarah Jane's attic at 13 Bannerman Road, but left in order to defeat Travist Polong. He was then present at Sarah Jane's wedding to Peter Dalton, where he helped the Doctor, Luke, Rani and Clyde to defeat The Trickster. (SJA: The Wedding of Sarah Jane Smith) He was then summoned to the International Gallery when Luke put Clyde's drawing of him inside a cloud of mystic drawing-animation energy and he defeated The Abomination, before returning to the attic. (SJA: Mona Lisa's Revenge) He then helped defeat the Slitheen family, before he was brought to Park Vale Comprehensive School by Clyde to help him with his test. He then helped defeat the Rakweed, before returning home. (SJA: The Gift)

In 2056, Sarah left K-9 to a boy who would help later alongside with Drax to help search for the Sixth Doctor who was held captive by Omega. (Search for the Doctor)

2050 K-9

The future K-9
"Who am I? My name is K-9! I do not know where or when I come from."
K-9's first words.

After Mark I sacrificed himself to destroy Jixen warriors, a boy called Starkey retrieved his regeneration circuit and he was rebuilt as a much more advanced model, but had no memories of the Doctor. He stayed at the house of Alistair Gryffen, where he ran tests on K-9, but did not tell The Department. K-9 tried to kill Starkey, as he was sprayed with Jixen genetic matter and therefore registered as a Jixen. Starkey managed to convince him that he was not an enemy and K-9 gave him his dog whistle so that he can be summoned whenever needed. (K9TV: Regeneration) This series, however, may not be canon.

K-9 opens fire


"The small female is hostile."
―K-9 on Kelsey Harper

K-9 had a very consistent personality from model to model. He had a polite, formal manner with just a hint of pedantry bordering on condescension. Though he often displayed feelings such as sorrow (DW: The Invasion of Time) and self-regard (DW: School Reunion), he often stated that he had not been programmed to have emotions. (SJA: Invasion of the Bane)

He did not use contractions just as "you've" for "you have" and addressed others by titles such as "Master", "Mistress", "Doctor-Master" (to refer to the Doctor) or "Young Master" (Adric and in one instance Clyde). Though he did not seem to resent his subordinate status, he tended to side with the Doctor's companions over the Doctor himself and at times showed a dark side, regarding other artificial intelligences with contempt (DW: The Invasion of Time) and relishing a brief chance to act as a figure of power (MA: The Well-Mannered War)

K-9 at the beach. (DW: The Leisure Hive)

He usually did not engage in computer-like literal thinking, though on one occasion he followed Romana's instructions to "forget it" to the letter and erased all his knowledge of tennis from his memory banks. (DW: The Stones of Blood)

Because of him having great intelligence, he likes to bore people with facts and does not immediately stop when asked as he did to Leela on Pluto. When being told that he would have to stay behind in the TARDIS, K-9 would often argue giving the Doctor reasons why he should go such as "he would be a good dog." This shows K-9's willingness to assist the Doctor. He also has showed to have great intelligence and skill at chess as he was able to beat the Doctor in six moves (This may only be because he is programmed with all chess games since 1886.) (DW: The Sun Makers, The Androids of Tara) K-9 was revealed to have an aggression mode. (DW: State of Decay)


The new and improved fourth version of K-9. (DW: School Reunion)
"Oi! Listen, in the year 5000, this was cutting edge!"
the Doctor

The mechanics of K-9 Mark I included rotating ear-probes, telescopic 'eye' probe, extendable nose, flashing lights on the top and the 'eye' panel, waggling tail antennae, and ticker-tape tongue. The head could also move up and down. The shell was painted in gold/grey metallic. Around K9's neck was a tartan collar, from which hung a silver disk. (DW: The Invisible Enemy)

After K-9 Mark I was left behind with Leela on Gallifrey, The Doctor built a improved K-9 Mark II. While the cosmetic changes were minimal (including the new metallic charcoal paint-work), in terms of series continuity K-9's character underwent a vast change. Gone was the product of 5000 AD technology, as was the case with Marius's version. This new K-9 was a product of the Doctor's own technology and values. The gun was now only capable of stunning, not killing and K-9 now responded to a dog-whistle. K-9 also featured a vast memory-bank, seemingly a mixture of the Mark One model, the Doctor's own memory and knowledge, and that of the TARDIS. (DW: The Invasion of Time)

"Why does he look so... disco?"
Rose Tyler on K-9 Mark III

When the Doctor left Sarah Jane Smith on Earth, he created K-9 Mark III to be Sarah's new companion. The new mechanics of K-9 Mark III included larger wheels in conjunction with a front and back-wheel drive. K-9 was also given a brand new coat of paint (this time a metallic-blue) and a handle on the top of the shell to make carrying him easier. (KAC: A Girl's Best Friend)

When the Doctor created K-9 Mark IV to replace K-9 Mark III, he added a shiny metallic blue paint job and a number of improvements over Mark IV including an omniflexible hyperlink facility. (DW: School Reunion) Later, though, K-9 reverted to his old, dark green color. (SJA: Invasion of the Bane) In episode 2 of The Lost Boy Sarah Jane unleashes K-9 Mark IV to battle Mr Smith. Before and after the battle K-9 displays a teleport facility and utilises a laser weapon similar to the previous K-9s'. (SJA: The Lost Boy)


Behind the Scenes

  • In an interview, the writers originally wanted to name K-9 "Pluto", after the Disney character; however, Disney refused permission.

From The Vault

race: Cyberdog
role: Recruitable NPC
location: NCR
appearances: Fallout 2
quests: Fix K-9
dialogue file: Cck9.msg

K-9 is a joinable NPC in Fallout 2.

K-9 the Robotic Canine Companion can be found at Navarro in Doc Schreber's office. You'll need the K-9 Parts found elsewhere to reactivate him.

K-9 hates Doc Schreber with a passion, but only because it considers Schreber evil. The cyberdog will only follow you after he's dead, as long as your character isn't a Childkiller or have a Karma rating of -101 or less. If you do become a Childkiller or drop your Karma below the limit, he'll leave the party forever.


How to obtain K-9

To obtain K-9, you must complete two requirements. One, you must repair K-9's leg mechanisms with a servo-motor (one is available in the mechanic's shop on the Enclave base Navarro - when you request the Vertibird plans from Raul, keep searching his toolboxes and lockers until you find it). Using this servo-motor on K-9 will fix him. Two, you must kill Doc Schreber. Due to the room being soundproofed, make sure the lab door is closed before you do it.


K-9 has level progression. Level 5 stats in brackets.

Behind the scenes

In the British science fiction show, Doctor Who, The Doctor traveled at one point with a mechanical dog with the name K-9.


Because he is a "dog" character, he could be Fallout 2's "official" variant of Dogmeat.

From Wookieepedia, the Star Wars wiki.

K-9 droid, Arf

K-9 series droids were a type of automated toy, designed to be a companion and plaything for young children.


Functions and components

A K-9 was about forty centimeters long, and although it was intended to imitate a dog in both appearance and behavior, it had a box-like shape. Although images of the K-9 show the droid had four legs, it appears they moved via a small bank of repulsorlift coils located on the underside.

K-9's were voice controlled and could be programmed to respond only to specific individuals, such as their owner's. The model was equipped with standard, basic recording capabilities including audio and flatscreen video recording, which could be replayed by projecting the image from the optical sensors onto a flat surface, such as a wall. However the series was not equipped with holorecording or playback capabilities.

A small panel on the back of a K-9 held a DNA-sample reader, which if pressed by someone with the correct clearance would open a secret panel hidden on the droid's body. The hatch could not be easily identified and could not be penetrated by most sensor scans. This made the droids useful for keeping safe items that the owner wanted to remain hidden - such as a lightsaber for example.

Behind the scenes

The K-9 droids are probably references to the K-9 robotic dogs from Doctor Who; besides the name, the Star Wars K-9 is described as having a similar appearance and method of locomotion.

From Teletraan I: The Transformers Wiki

K-9 is a Maximal in the Beast Wars portion of the Generation One continuity family.
Not pictured: weird guy with time-travelling police box.

K-9's alternate form, a German Shepherd, is befitting of his function as a guard. His canine senses keep him aware of his surroundings at all times. His doggie agility and strength give K-9 the edge against any intruding Predacons. If that fails, he can always try leaking lubricant on his opponents as a last-ditch effort—it might cause them to rust.

Italian name: Dingo[1]



Intimidation Game

Voice actor: Brian Dobson

The Tripredacus agent Flamewar was held prisoner and interrogated by a group of Autobots and Maximals which included K-9. However, the interrogation was a facade, and the entity appearing to be K-9 was in fact a disguised Max-B. Intimidation Game

IDW Beast Wars comics

K-9 was one of the protoforms jettisoned from the Axalon on prehistoric Earth. He was activated and put in chronal phase by Razorbeast at Magmatron's request, but was protected from Magmatron's Predacon shell-program by Razorbeast's viral code.

Soon after awakening, he joined up with Torca's militia along with Bantor, Noctorro, Stinkbomb and Armordillo. During their journey to meet up with Razorbeast, Torca got stuck in some mud, and K-9 and the others helped free him. After following Razorbeast's signal for days and picking up more Maximals along the way, K-9 and the rest rushed into battle against Magmatron's Predacons. The Maximals won that altercation and awaited rescue from Cybertron. The Gathering

The day he got back to Cybertron, he was killed by Shokaract. The Ascending issue 4


Beast Wars

  • K-9 (Deluxe, 1997)
K-9 transforms into a German Shepherd and features a missile launcher concealed in his tail. The missiles store in his robot abdomen. His beast-mode back also forms a riot shield.
This toy is an extensive (if not complete) retooling of Wolfang. Almost all of his parts have been given new moulding, often becoming larger, making him somewhat more massive than his predecessor. The only part of his body not changed is his head sculpt. K-9 was then used as the basis for a second retooling into the Beast Wars II toy Max B.
Despite the cosmetic changes, K-9 essentially works exactly the same as Wolfang, with very little change to play value. He even retains the "mutant mask" gimmick (the mask was retooled, even if his head wasn't), even though by the time of his release, that feature had been dropped from new-mold toys. The only mechanical change is that his back shield's handle was simplified to make it easier to transform.


  • In the comic, K-9 gained his beast mode on ancient Earth...waaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaay before the German Shepherd breed came into existence. (Though his beast mode's depiction in the comic is a fairly poor representation of a Shepherd, so make of that what you will.)
Is that you back there?
  • Trent Troop, who designed the Maximal Command Security Force, based the colors of one member (the one with the axe and shield) on K-9 (privately dubbing him "9K"). Whether any official material ever picks up on this remains to be seen.


  1. This name may have only been used on the cross-sell for the English/Spanish/Italian "video-pack" release of Airazor. However, a carded example of trilingual European English/Spanish/Italian K-9 has not been found at this time, so this is uncertain.
