The Power of Kroll is the fifth serial of the 16th season of the British science fiction television series Doctor Who, which was first broadcast in four weekly parts on BBC1 from 23 December 1978 to 13 January 1979.
The serial is set on the third moon of the human colony world Delta Magna. In the serial, a methane catalysing refinery's operations in the swamp disturbs the giant squid Kroll, which grew in size after ingesting the fifth segment of the powerful Key to Time. When Kroll surfaces, it subsequently rampages on the moon.
The Fourth Doctor and Romana have arrived on the third moon of Delta Magna, searching for the penultimate segment of the Key to Time, finding themselves caught in the middle of a dispute between the crew of a methane refinery and the natives (known as 'Swampies'). The Swampies claim the crew have disturbed the waters, and will incur the wrath of Kroll. It turns out Kroll is a giant squid which surfaces to feed every few centuries and is the source of the abnormally large amount of methane being mined. Once of normal size, it ingested the fifth segment of the Key to Time and began to grow and became a god-like figure to the Swampies and their descendants.
After Kroll awakens and begins to attack both the Swampies and the refinery indiscriminately, the Doctor uses the tracer to retrieve the segment of the key, which destroys Kroll and instigates cellular regeneration within the creature to produce hundreds of normal-sized squid. This process not only saves the planet's inhabitants but removes the source of methane from the refinery. The Doctor and Romana return to the TARDIS and set off on their next adventure.
When script editor Anthony Read asked Robert Holmes to write the story, there were two requirements: that it include the largest monster in series history and that Holmes minimise the humour that many scripts from the era were known for. This second requirement was a request from higher up at the BBC. Early titles for the story were Moon of Death and Horror of the Swamp. Holmes said that he considered the idea of a large monster a mistake given the budgetary constraints at the BBC and named The Power of Kroll as his least favourite Doctor Who story.
Extensive location filming took place in Snape, Suffolk around the River Alde from Monday 18 September 1978 to represent the marshes featured in the script. Nine days of location filming were afforded to the serial, including two night shoots, more than is usual for a Doctor Who story. Studio sequences were taped during October 1978. The serial was directed by Norman Stewart, who had directed the Underworld story a year previously. This was his final assignment on the programme. The actors playing Swampies were coloured green with a special water-resistant dye ordered from Germany. Unfortunately, the make-up artist failed to order the special dye remover, with the result that many of the actors had to take chemical baths to get the green dye off, and many had a green tint for a long period after production was finished. Costume designer Colin Lavers introduced a new tweed coat for the Doctor, which sported four flying duck brooches on its lapels. Around this time, producer Graham Williams fell ill and his duties were taken on by Anthony Read and production unit manager John Nathan-Turner, assisted by Blake's 7 producer David Maloney.
Among the cast were a number of actors who had previously appeared in Doctor Who playing other characters. The most notable of these was Philip Madoc who had previously appeared in The Krotons (1968–69), The War Games (1969) and The Brain of Morbius (1976). He had initially been invited to play Thawn, but the role was given to George Baker, who then pulled out. Madoc agreed to play the part of Fenner when Alan Browning, who was slated to play Fenner, fell ill before the start of production, but was dissatisfied with the role. John Leeson, best known as the voice of K9, appears in this story as Dugeen. This is his only on-screen appearance in Doctor Who and was given the role due to the fact that K9 doesn't appear in this story. (The role had previously been offered to Martin Jarvis.) Neil McCarthy previously played Barnham in The Mind of Evil (1971), while John Abineri previously played Van Lutyens in Fury from the Deep (1968), General Carrington in The Ambassadors of Death (1970) and Richard Railton in Death to the Daleks (1974).

In their book The Discontinuity Guide (1995), Paul Cornell, Martin Day, and Keith Topping wrote that The Power of Kroll was "very slow" with little humour, and "horribly acted" aside from Madoc and Abineri. They also criticised the "unconvincing" realisation of Kroll. In 2011, Mark Braxton of Radio Times gave a negative review of the serial, describing it as uninteresting with poor effects, "tepid dialogue and dull characters". However, he felt that some parts were "enlivened by Tom Baker's sprightly performance". DVD Talk's Justin Felix gave the story two and a half out of five stars, calling it the "least inspired" story of The Key to Time. While he praised Baker and Tamm and their dialogue, he criticised the "flimsy" concept and the Swampies.
