K9 Mark II was the second K9 known to the Fourth Doctor. Based on a robot originally built by Professor Frederick Marius, he was apparently constructed by the Doctor himself. (TV: The Invasion of Time)

The unit was particularly associated with Romana, having served both Romana I and Romana II. Indeed, he stopped travelling with the Doctor at the same time as the second Romana, with whom he remained in E-Space in order to assist with the liberation of the Tharil species. When Romana returned into N-Space, K9 joined her on Gallifrey. Once on the Time Lords' homeworld, he continued to serve Romana as she ascended to the post of Lady President of the High Council. (AUDIO: Weapon of Choice, et al)

Whilst on Gallifrey, he frequently liaised with K9 Mark I, Leela's version of the robot, whom he found to be "inferior". (AUDIO: Square One, PROSE: Jealous, Possessive)

Biography Edit

After K9 Mark I decided to stay on Gallifrey with Leela, the Doctor already had Mark II (or at least its components) prepared and in storage. (TV: The Invasion of Time, AUDIO: The Time Vampire)

K9 and the Doctor Edit

DWM 26 K9 thinks that he's a cat

K9 is convinced that he is a cat, perched atop the TARDIS rotor. (COMIC: Doctor Who and the Star Beast)

For a short time, the Doctor and K9 traveled alone without other companions.

Quest for the Key to Time Edit

This version of K9 accompanied the Doctor and Romana I on their quest to locate the segments of the Key to Time. The Doctor used a dog whistle to alert K9 and to summon him. (TV: The Ribos Operation)

K9 killed pirates who were attacking other planets from their own, Zanak. (TV: The Pirate Planet)

On Tara, K9 disabled several guards in the employ of Count Grendel of Gracht. He travelled in a boat with the Doctor in a passage under the Count's castle, cutting a way through with his blaster. The Doctor left K9 in the boat as he went to foil the Count's plot. (TV: The Androids of Tara)

When the TARDIS landed on Delta III, the swampy terrain made it impossible for K9 to accompany the Doctor and Romana. He remained in the TARDIS. (TV: The Power of Kroll)

While searching for the sixth segment, they landed on the planet Atrios. K9 was tricked into entering a scrap metal furnace, but the Doctor rescued him before he was melted. K9 transmatted to the planet Zeos. K9 told the super-computer Mentalis it was good to talk with someone who was not as illogical or unpredictable as a flesh-and-blood being. K9 again transmatted, arriving on the third planet. He was turned by the Shadow to do his bidding, but the Doctor was able to remove the control matrix implanted by the Shadow, restoring him to his former self. (TV: The Armageddon Factor)

Further adventures Edit

K9's brain

The Doctor inspects K9's brain circuit. (TV: Destiny of the Daleks)

In an attempt to evade the Black Guardian, the Doctor activated the TARDIS' randomiser and programmed it to visit approximately 1,000 planets, which took about a month. He left K9 aboard the TARDIS during this time while he and Romana took up residence in a London townhouse in 1929. (AUDIO: The Auntie Matter)

While making repairs to K9's brain circuit, the Doctor found that K9 had contracted laryngitis and could not speak. K9 was left in the TARDIS while the Doctor and Romana II battled the Daleks and Davros. (TV: Destiny of the Daleks) Later he remained patiently in the TARDIS while the Doctor and Romana visited Paris. (TV: City of Death)

After his voice returned, K9 sounded different for some time. On Chloris, K9 attacked some Wolfweeds and the soldiers of Lady Adrasta. The Wolfweeds swarmed about him and entwined him in fibres. He was taken by Adrasta, as metal was valuable. (TV: The Creature from the Pit)

K9 was left inside the TARDIS when the Doctor and Romana went punting in Cambridge to meet Professor Chronotis. After several hours of being "nowhere", (WC: Shada) due to the Doctor and Romana being taken out of time by Borusa, (TV: The Five Doctors) the Doctor went back to the TARDIS, demanding everyone to put their bathing suits on as they were going to Brighton. The Doctor and Romana, though retaining memories of the punting trip, had forgotten they intended to visit Chronotis. The Doctor said that they had intended to be back "before lights out", but "went on somewhere else", according to Romana, after only being away from the TARDIS for two hours and twenty-one minutes. (WC: Shada)

Ivo and K9 make peace

Ivo apologises to K9. (TV: State of Decay)

In E-Space, K9 led the attack on the castle of the Three Who Rule. He shot many of the guards, doing most of the work. The Doctor made Ivo apologise to K9 for doubting him. (TV: State of Decay)

Damaged by the time winds, K9 Mark II could not cross back into N-Space with the Doctor, and decided to stay at the Gateway with Romana, to help her free the remaining Tharils from slavery. (TV: Warriors' Gate)

Adric greatly missed K9 after he left the TARDIS. (AUDIO: Psychodrome)

The Doctor chose not to replace K9 again, though he did build/obtain a Mark III that he gifted to Sarah Jane Smith (TV: A Girl's Best Friend) and, upon the destruction of Mark III, rebuilt him into K9 Mark IV to give to Sarah Jane. (TV: School Reunion)

On Gallifrey Edit

This section needs a cleanup.

Some of this is plot summary that has little to do with K9.

Mark II was repaired. He accompanied Romana when she returned to N-Space. During Romana's term as President of Gallifrey, K9 Mark II served as her aide and advisor. (PROSE: Lungbarrow)

Remembering he had intended to visit his friend, Professor Chronotis in 1979 Cambridge back in the days his fourth incarnation travelled with Romana II, (WC: Shada) before he and Romana were taken out of time by Borusa for several hours, (TV: The Five Doctors) the Eighth Doctor came to Madame President Romana and K9 on Gallifrey to investigate what he was supposed to have been doing before his fourth incarnation, annoyed he was "nowhere" for several hours, forgot and went off to Brighton.

K9 was able to trace the sphere that attacked the Doctor to the ship of Skagra. The Doctor, Chris Parsons, Romana and K9 travelled to it. Chris and K9 were imprisoned in the ship's brig until the Doctor could release them. When the Doctor's meddling on board Skagra's ship awoke a Krarg, K9 bought time for the Doctor and Chris by fighting it off. The Krarg attacked Think Tank and destroyed its systems.

Using The Worshipful and Ancient Law of Gallifrey as a "key", Skagra took Romana with him to the Time Lord prison planet, Shada, to take the mind of the criminal, Salyavin, to make all inhabitants of the universe share Skagra's mind. Discovering Chronotis' TARDIS on board Skagra's command ship, the Doctor chased after him. After arriving, Skagra stole the mind of the Professor, who was actually Salyavin. Skagra began placing fragments of the minds he had stolen into his Krarg servants.

As Skagra left Shada in the Doctor's TARDIS, the Doctor created a tunnel to link the the two TARDISes in the time vortex together. This broke Chronotis' TARDIS. However, K9 was able to help repair it. The Doctor arrived through the TARDIS' "back entrance" and improvised a mind control helmet to command the Krargs, as part of the shared mind contained the Doctor's own thoughts. After the TARDIS landed on Skagra's command ship, the conflicting commands from the Doctor and Skagra destroyed the Krargs, the surviving victims whose minds were taken by the sphere returning to their bodies. The Doctor and Romana ordered K9 to shoot at the Krarg commander, leading it towards the vats of unborn Krargs, destroying it and the vats. (WC: Shada)

Personality Edit

K9 was faithful to the Doctor and called him "Master" — calling him "Doctor" only once, and this was when under the control of the Shadow. (TV: The Armageddon Factor) He corrected the Doctor when necessary. (TV: The Ribos Operation) He was happy at the prospect of going on holiday (TV: The Ribos Operation) and to have a conversation with the super-computer Mentalis, declaring it better than talking to unpredictable life forms. K9 branded optimism illogical, bordering on insanity. (TV: The Armageddon Factor) He declared that he didn't feel anything nor did he find it necessary to do so. (TV: Warriors' Gate)

K9 had no problem with killing those who threatened him, such as Count Grendel's men or the guards of the Three Who Rule. (TV: The Androids of Tara, State of Decay) He only killed in self-defence, as his programming dictated. (TV: The Creature from the Pit)

The Doctor and K9 were fond of each other, as the Doctor described K9 as his "best friend" and when they were due to be destroyed in the TARDIS — which they actually survived — the Doctor placed a first place ribbon onto K9, and K9 thanked him.

The Doctor said that K9 had saved his life lots of times. (TV: Nightmare of Eden)

Features Edit

DWM 31 K9 vs Dalek

K9's laser blast disrupts and shatters a Dalek shell. (COMIC: Doctor Who and the Dogs of Doom)

After K9 Mark I was left behind with Leela on Gallifrey, the Doctor built an improved K9 Mark II. Gone was the product of Marius' 5000 AD technology. This new K9 was a product of the Doctor's own technology and values. The gun was now only capable of stunning — not killing — and K9 now responded to a dog-whistle. K9 also featured a vast memory-bank, seemingly a mixture of the Mark I model, the Doctor's own memory and knowledge, and that of the TARDIS. (TV: The Invasion of Time)

Unlike Mark I, Mark II could climb stairs, (PROSE: Heart of TARDIS) but it took a great deal of time and energy. (PROSE: The Shadow of Weng-Chiang)

K9 was also equipped with a stealth mode. However, he did not use it until boarding the space platform Fortune II in the Proxima System, as "no one ever asked." (AUDIO: The Final Phase)

His blaster ray had an accuracy of 98%. (AUDIO: Ascension) It notably deadly against Daleks. (COMIC: Doctor Who and the Dogs of Doom)

K9 claimed that he was shaped like a dog because "the human ego requires a familiar reference point to aid in adjusting to new concepts. Animal forms are comforting to the majority of humans." (PROSE: Housewarming)

Behind the scenes Edit

  • One of the reasons the production team replaced K9 Mark I was because it was difficult to control. They overcame this problem when they built K9 Mark II.[source needed]
  • In the webcast Shada, K9 mentions that Earth's soil interfered with his traction (an in-joke referring to the original prop's real-life difficulty travelling in a straight line).

Casting Edit

John Leeson provided K9 Mark II's voice in almost all appearances. Another actor, David Brierley voiced him in The Creature from the Pit, Nightmare of Eden and The Horns of Nimon, while Roy Skelton, better known as a Dalek voice actor, provided the character's voice in Destiny of the Daleks when all was required was a croaking sound. Leeson took over the role again from The Leisure Hive onward.
