The Krotons is the fourth serial of the sixth season of the British science fiction television series Doctor Who, which was first broadcast in four weekly parts from 28 December 1968 to 18 January 1969. The story is most distinguished as the first contribution of long-time Doctor Who writer and script editor Robert Holmes.

Plot

On an unnamed planet, a race called the Gonds are subject to the mysterious Krotons, unseen beings to whom they provide their brightest intelligences as “companions”. Thara, son of the Gond leader Selris, is the only one of his race to object to this practice; those who have become companions before have never been seen nor heard from again. The Doctor, Jamie and Zoe arrive in time to witness the death of one of the chosen companions, Abu, who is vaporised by smoke sprayed from nozzles on either side of the doorway from which he emerges, and intervene to save Vana, the other selected for this fate, using her survival as a means to convince Selris and the Gonds of the malign influence of the Krotons on their society. The Doctor calls it "self-perpetuating slavery” by which the brightest in Gond society have been removed. Similarly, there are large gaps in their knowledge, especially relating to chemistry. This situation has been in existence for many years since the Krotons arrived in their spaceship, releasing a poison that polluted the lands beyond the Gond city — which the Gonds call 'the Wasteland' — and killed much of the Gond population.

Thara uses the disquiet of the situation to lead a rebellion and attack the Teaching Machines of the Krotons in the Hall of Learning. This prompts a crystalline probe to appear and defend the Machines, and warn the Gonds to cease their rebellion. Zoe now tries the Teaching Machines and is selected to be a “companion” of the Krotons. The Doctor elects the same fate and both are summoned into the Dynotrope where they are subjected to a mental attack. Zoe deduces that the Krotons have found a way to transfer mental power into pure energy, while the Doctor busies himself with taking chemical samples of the Kroton environment. Circumstances now trigger the creation of two Krotons from chemical vats within the Dynatrope (the Kroton spaceship). The newly-created Krotons capture Jamie, but are really seeking the Doctor and Zoe, the “High Brains”, who have now left the Dynatrope. It takes Jamie quite some time before he is able to make an effective escape but the Krotons pursue him and use their weapons to gas Jamie.

Eelek and Axus, two councillors previously loyal to the Krotons, who begin to rally for all-out war with the Krotons, have now seized the initiative in Gond society. The Krotons chase the Doctor, Zoe, Eelek and Axus throughout the planet, through ancient pyramids and forests. Elek and Axus fight with the Krotons and destroy them. The more level headed Selris is deposed, but warns that an all-out attack will not benefit his people. Instead he has decided to attack the machine from underneath by destabilising its very foundation in the underhall. Eelek has Selris arrested and also reasserts control by negotiating with the Krotons that they will leave the planet if provided with the two “High Brains” who can help them power and pilot their ship. Zoe and the Doctor are forced into the Dynatrope and Selris dies providing them with a phial of acid which the Doctor adds to the Kroton vats. Jamie recovers and destroys the Krotons by using a spare gas weapon; he is chased by more Krotons which leads him to a lake of acid. Jamie throws the acid over the Krotons and they are destroyed. Beta approaches Jamie and tells him they may have found a weapon. The Krotons prepare to use the vats to destoy the Gonds. Outside, Jamie and the scientist Beta launch an attack on the structure of the ship using sulphuric acid. This two-pronged assault destroys the tellurium-based Krotons and their craft. The Dynatrope dissolves away and the Gonds are free at last — choosing Thara rather than the cowardly and ambitious Eelek to lead them.

Leaving the Gonds to find their own answers for the future, the Doctor, Jamie and Zoe slip away back to the TARDIS and new adventures...

Continuity

• The Krotons also feature in the Eighth Doctor Adventures spin-off novel Alien Bodies by Lawrence Miles.
• They also appeared in the Big Finish audio drama Return of the Krotons with the Sixth Doctor.

Production

• Working titles for this story included The Trap and The Space Trap.
• Holmes had originally submitted The Trap to the BBC as a stand-alone science-fiction serial in 1965. Head of Serials Shaun Sutton rejected the serial as being not the kind of thing the BBC was interested in making at the time, but suggested the writer pitch it to the Doctor Who production office as an idea for that series. Holmes did so, and although story editor Donald Tosh was interested, the scripts went no further at the time.
• Some years later, assistant script editor Terrance Dicks found the story in the production office files when clearing a backlog, and decided to develop it with Holmes as a personal project, in case other scripts fell through. When the latter event occurred, Dick Sharples script Prison in Space a comedic dystopian tale where females rule with dollybird guards proved unworkable, Dicks was able to present the serial to his superiors as a ready production. Director David Maloney agreed the serial was viable, and it went before the cameras very quickly as an emergency replacement.
• Robert La'Bassiere is actually a pseudonym for Robert Grant, who requested that he be credited under this name for his appearance as one of the Krotons.
• Scenes set on the planet's surface were filmed at the Tank Quarry and West of England Quarry on the Malvern Hills.
