History Recap / DoctorWhoS4E6TheMoonbase

* ArtisticLicenseChemistry: As ''Magazine/DoctorWhoMagazine'' later pointed out, Polly's "cocktail" of solvents would end up reacting against each other and turn into a thick brown gunge, totally different from the clear liquid presented in this story. That issue also guessed that she was throwing any solvent she could at them in the hopes that something would work.

* AllThereInTheManual: Later expanded universe sources, ''Doctor Who: Cybermen'' and its audio adaptation ''The ArcHive Tapes'', identify the Cybermen seen here as descendants of the space-faring [=CyberFaction=] who left Mondas behind, their earlier InUniverse forms seen in "[[Recap/DoctorWhoS5E7TheWheelInSpace The Wheel in Space]]" and "[[Recap/DoctorWhoS6E3TheInvasion The Invasion]]". These Cybermen ultimately [[Recap/DoctorWhoS5E1TheTombOfTheCybermen settle on the planet Telos]] and are recognised by historians as a new subspecies, the [=CyberTelosians=].

A second wave of Cybermen invade across the Moon's surface but the Graviton quickly sends them flying off into space and the travelers go on their merry way.

* ContinuousDecompression: This story features the subtrope of characters struggling to seal the hole as the air rushes out. One fan actually did the calculations to see how long it should have actually taken for decompression to happen. The results were something on the order of a few seconds. The scene in the episode lasted much longer, obviously.

* OhCrap: The Doctor, followed slowly by everyone else in the room has a rather epic one at the conclusion of one episode when the base leader argues that there can't be any Cybermen in the base because they've searched every single room for them...except the one they're in right now. Guess where the Cyberman turns out to be hiding?

* TheSiege: Mainly happens in episode 4 when the infiltration of the Moonbase has already been exposed. The Cybermen throw subtlety to the wind and march in force, openly attacking the base.

* SequelEpisode: To [[Recap/DoctorWhoS4E2TheTenthPlanet The Tenth Planet]].

Cybermen on the Moon, as the perennial favourites make their second appearance in essentially a retread of their first.

* AllThereInTheScript: The Cybermen originally had names as in [[Recap/DoctorWhoS4E2TheTenthPlanet The Tenth Planet]]. For example, the lead Cyberman was named Tarn.

* StayInTheKitchen: Ben tries this on Polly. She doesn't listen.

* TrueCompanions: From the scenes where we see Captain Hobson and Second-In-Command Benoit conversing together, you can see that they care for each other.

* BlackDudeDiesFirst: The base is staffed with an international group of scientists, all white except for one black man. He is the first to be killed, getting bumped off in Episode 1 [[spoiler: although it is later revealed that he was just kidnapped by the Cybermen and made a partially-converted slave]].

** This is also why he wears a scarf, his shirt was designed before the name change and has letter J on it and the scarf was used to cover it up(for the most part)

It's 2070 AD and Earth's weather is controlled from a station on the Moon by means of the Graviton. The crew of the station are coming down with a disease that turns out to be a Cyberman-engineered poison. Polly and Ben realise that as Cybermen are part-plastic, solvents ought to harm them, and mix up a cocktail of chemicals which they use in fire extinguishers to defeat the Cybermen on the base.[[note]] [[http://tvtropes.org/pmwiki/pmwiki.php/Recap/DoctorWhoS12E5RevengeOfTheCybermen Gold]] [[Recap/DoctorWhoS19E6Earthshock will be [[Recap/DoctorWhoS25E3SilverNemesis used later]].
