History Recap / DoctorWhoS16E6TheArmageddonFactor

* StylisticSuck: The recruitment video seen the first scene of the story is deliberately produced and acted poorly.

* AntiClimax: The "Key to Time" story arc, which spans six stories and an entire season, ends without a proper resolution

* AntiClimax: The "Key to Time" story arc, which spans six stories and an entire season, ends without a proper resolution.

* ExpositionIntuition: At the beginning of part 6, Shap and Merac conveniently recap for us some recent events and the predicament the Doctor is in. Which is strange because these events happened on a different planet and no one present has been in communication with them.

The search for the last segment of the [[CosmicKeystone Key to Time]] takes the Doctor and Romana to the planet Atrios, which is embroiled in a war with its sister planet Zeos. The war has been going for years and is taking a serious toll, and there is a growing movement wanting to arrange a peace, but the Marshal of Atrios is determined to keep fighting until the Zeons are wiped out.

It turns out that all is not as it seems on Zeos (which is in fact completely deserted), and that a third party has been keeping the war going for his own purposes. The Doctor manages to get hold of the final segment - disguised as the Atrian Princess Astra - and complete the Key, while ending the war along the way.

The White Guardian appears on his viewscreen, congratulates him and asks for the Key. The Doctor refuses, reasoning that its power is such that no-one should possess it, and scatters its pieces again. The White Guardian is angry, and reveals that he is in fact the ''Black'' Guardian, who's been waiting around near the final segment for the Doctor to show up with the others. The Black Guardian threatens to kill the Doctor, who sets a randomiser on the TARDIS so that his travels will be unpredictable. Well, ''more'' unpredictable.

* FakeMacGuffin: The Doctor creates a false Key Segment in his plan to trap the Shadow's forces in a time loop. He knew, however, that the segment (and the time loop) would disintegrate over time; the goal was to buy himself more time.

* AGodAmI: played with

* SternChase: The beginning of one is the reason for the randomizer

* WeakenedByTheLight: The Doctor holds off the Shadow with a beam of light emmenating from the completed Key To Time. The TARDIS also produces a blindingly bright light as a form of defence against the Shadow, though his mooks are able to withstand it much more easily.

* YouDontHaveItIDontHaveIt: The Doctor's decision to scatter the segments through time and space once more upon realizing that the Black Guardian was disguising himself as the White Guardian.

* Malaproper: The Marshal. "Taste the moment of victory. Any second now, [[TheDeadliestMushroom beautiful mushrooms]] will blossom and burst!"

* XanatosSucker: The Marshal.

* ForeverWar

* StylisticSuck

* WeakenedByTheLight: The Doctor holds off the Shadow with a beam of light emmenating from the completed Key To Time.

* BeneathTheEarth: The whole third planet / [[NamesToRunAwayFromReallyFast plane of evil]] has very much the feel of this, in spite of the fact that it's an artificially constructed structure that looks quite space agey from the outside.

* AGodAmI

* StellarName
