The Armageddon Factor is a serial in the British science fiction television series Doctor Who, which was first broadcast in six weekly parts from 20 January to 24 February 1979. It is the last story in The Key to Time arc, and the last to feature Mary Tamm as Romana.

Synopsis

The quest for the final segment to the Key to Time brings the Doctor and Romana to Atrios, a world caught in a perpetual, stalemated war with its planetary neighbour Zeos. But the Black Guardian is closing in...

Plot

In their search for the final segment of the Key to Time, the Doctor and Romana arrive on the planet Atrios, which has endured a recent bombing by their neighbouring planet Zeos, with whom they are at war. The Marshal of Atrios is about to launch a counterstrike on Zeos, but the Doctor finds that Zeos is deserted save for the giant computer Mentalis, which is controlling the war. He also discovers that the true opponent is a third planet called the Planet of Evil, ruled by "the Shadow". The Shadow, an agent of the Black Guardian, has Princess Astra of Atrios captive, threatening to torture her if she doesn't give him the location of the final segment of the Key to Time (which she doesn't know).

After disabling Mentalis, with the assistance of Romana and K-9, the Doctor creates a substitute sixth segment out of chronodyne, which gives the Key enough power to create a time loop in which to trap the Marshal's ship (armed with missiles for the final strike) as well as the Mentalis control room (engaged in an automatic self-destruct sequence). On the Planet of Evil, the Doctor encounters an old Academy mate, a fellow Time Lord named Drax, who has been employed under duress by the Shadow but agrees to help the Doctor. Drax referred to the Doctor by the nickname "Thete", short for Theta Sigma. Drax also talked about him getting his doctorate. It wasn't until the Doctor reminded Drax that he was the Doctor, that he started to call him Doctor.

With K-9 and Astra now under his control, the Shadow wants the Key for himself, and forces the Doctor to retrieve it for him. The Doctor leads the Mute to his TARDIS and opens the door, but is suddenly shrunk to tiny size by Drax, using the dimensional stabilizer from his own (in-need-of-repair) TARDIS. (Originally, as implied by the Doctor's reaction, Drax was supposed to use the shrinking beam on the Mute, but deliberately shrinks the Doctor instead. Episode 5 ends on this scene, and it's only at the beginning of Episode 6 that Drax shrinks himself as well, having misinterpreted the Doctor's plan.)

The Mute returns to the Shadow with the Key, but the Doctor realises why the Shadow has requested it: Astra is the final segment, and is transformed in front of everyone. Using their diminished size, the Doctor and Drax smuggle themselves into the Shadow's lair inside of the now-restored K-9. Drax again uses the stabilizer, this time to return them to their normal size. The Doctor snatches the partially assembled Key and the final segment, and disappears with Romana and K9 in the TARDIS, assembling the Key after dealing with the Mentalis self-destruct (with the help of Drax) as well as the Marshal's missiles (using the TARDIS to deflect them onto the Planet of Evil).

The White Guardian appears to congratulate the Doctor on finding and assembling the Key to Time, and requests that it be sent to him. However, the Doctor, realising that it is actually the Black Guardian in disguise—due to his lack of compassion for the fate of Princess Astra—orders the Key to re-disperse. Enraged, the Black Guardian, now reverted to his true form, threatens him with death. In an attempt to shake him off, the Doctor fits a randomiser into the TARDIS console, sending it to an unknown location in time and space, and leaving the Doctor and the Guardian with no idea of where they are headed.

Continuity

• This is the sixth of six linked serials that comprise the whole of Season 16, known collectively as The Key to Time.
• Drax refers to the Doctor by the name "Theta Sigma". Not counting aliases like John Smith, this was the first time an actual name (albeit a nickname) was attached to the Doctor. Later, in The Happiness Patrol, the Doctor states that Theta Sigma was his old college nickname. Later, in "The Pandorica Opens" (2010 series), the characters for theta and sigma are the first two symbols under River Song's "Hello Sweetie" message written to the Doctor as the oldest words in recorded history.
• Drax also features in the novels Divided Loyalties (in a flashback sequence to the First Doctor's school days) and The Quantum Archangel (in an alternate timeline where he is working with the Master, the Rani and Mortimus to destroy Earth), as well and in Search for the Doctor, a "Make Your Own Adventure" book by Dave Martin.
• Valentine Dyall would return as the Black Guardian in the Black Guardian Trilogy, consisting of the Fifth Doctor serials Mawdryn Undead, Terminus and Enlightenment.
• The fate of Princess Astra is revealed in the Big Finish Productions audio story The Chaos Pool, the third in new series of Key to Time stories that start with The Judgement of Isskar. They reveal that the Doctor's use of a substitute sixth segment for the Key to Time disrupted the balance of the segments and caused them to decay, resulting in them causing significant damage to the Web of Time. Chaos Pool also explains Romana's decision to regenerate and take Astra's form in the next TV story Destiny of the Daleks.
• In the spin off series The Sarah Jane Adventures episode The Wedding of Sarah Jane Smith, The Trickster mentioned how the Doctor once held the Key to Time.
• Footage of the Black Guardian from this story forms the final part of a montage of the Fourth Doctor's enemies just prior to his regeneration in Logopolis.^{[citation needed]}
