->'''The Doctor:''' Androzani Major was becoming quite developed last time I passed this way.\\
'''Peri:''' When was that?\\
'''The Doctor:''' ...I don't remember. I'm pretty sure it wasn't the future.
-->-- '''The Fifth Doctor''', reminiscing on how hard it is to try and keep his travels straight.

The one where the Doctor fondles a bat.

Creator/PeterDavison's final episode, ending his tenure at an even twenty, and the first time Creator/GraemeHarper directed, opting to go beyond the traditional approach to studio filming. Rather than be a director who would go through the motions of filming with generic stage direction that felt static and stilted, he got direct with the actors and used a bold and groundbreaking dynamic style of filming, the result being what to this day remains one of the best episodes of ''Doctor Who'' ever made. Davison lamented that if more of his tenure had included Harper's directing approach, he might have stayed on the series longer.

Landing on the planet of Androzani Minor, the Doctor and new[[note]]New to TV, anyway; in the audios, Five has several adventures with Peri between the previous serial and this one.[[/note]] companion Peri go out of the TARDIS to wander around a very, very exotic alien planet. They quickly (and more or less in this order) find themselves under attack from random people, contract a nasty rash by stepping into a cobweb, get captured, jailed, and then shot. [[note]]In retrospect, the Doctor also seems to be taking the leaving of Turlough and the loss of Kamelion from the last episode rather well.[[/note]]

Luckily, as it turns out, the Doctor and Peri that were shot were actually ''android duplicates'' rather than the real thing. The real Doctor and Peri, on the other hand, now find themselves the eternal "guests" of the mysterious Sharaz Jek, who hangs out in the lower caverns wearing a black-and-white jumpsuit and a trippy ''Franchise/ThePhantomOfTheOpera''-style mask. Jek has rather... [[IHaveYouNowMyPretty unsavory intentions]] for Peri. Also, there's a dragon-like thing roaming about, but that's neither here nor there.

Peri and the Doctor compare their rashes and increasing dizziness; a more senior "guest" of Jek's sees this, and smugly tells them that they are now suffering a slow and painful death at the hands of "spectrox toxaemia". It's said to be incredibly lethal. Before a cure can be found, the Doctor and Peri are separated -- with the Doctor being shot at (and getting a head wound) and kidnapped by Stotz and his gang (for interrogation at Androzani Major). He's blindfolded and handcuffed to a wall, but manages to escape by burning his handcuffs off (and burning himself a bit, too), takes over the space ship and tries to manually crash land it while snarking at his captors. He's also still dying. The gang literally lasers a hole through the cockpit door, and the Doctor scrambles out of the ship, barely able to stand anymore but running with all his might.

Meanwhile, the story takes an unexpected nose dive into PsychologicalHorror and political intrigue. Jek falls madly in love with an increasingly unconscious Peri, but she's terrified when she sees his burned face underneath the mask, and he goes into a VillainousBSOD. The local president, who's 85 but looks 50 thanks to [[SpiceOfLife the local spice]], is caught up in an arms race conflict full of corruption. He's deposed by his lackey by creative use of an elevator shaft, and the lackey is quickly deposed by his smug secretary lady using the regular legal system. It all results in death. [[KillEmAll Lots and lots of death]].

The Doctor returns to Jek's place and (using his [[BizarreAlienBiology respiratory bypass system]]) goes off into deep, nearly airless caves to retrieve the cure for his and Peri's cobweb-related condition: space bat milk. [[OffscreenMomentOfAwesome Sadly]], we don't get to see Peter Davison milking a bat. Luckily, he manages to carry her out in time for redeemed-villain Jek to die a HeroicSacrifice. The Doctor carries an unconscious Peri along the alien landscape until he trips just before reaching the TARDIS -- dropping Peri and one of the two doses of antidote. He crawls in, locks the door, drags himself to the console and gets the TARDIS to vworp away half a second before the ground underneath her explodes.

The Doctor gives Peri the remaining antidote -- actually worried that he might die from the poisoning rather than regenerate. [[Recap/DoctorWhoS21E7TheTwinDilemma As we all know]], though, [[TheNthDoctor this is not the case]], and as visions of his companions and the Master surround him, he turns into the [[Creator/ColinBaker Sixth Doctor]]. This new chap, with curly blond hair atop his head, gives his sardonic wit a whirl and insults Peri with a condescending remark. Six believes this regeneration is for the better and gives the camera a big, confident, full of himself smile.
----
!!Tropes
* AllForNothing: Almost every action and event is rendered pointless by almost everyone dying. What's more, the only thing the Doctor was able to accomplish was saving Peri's life; meanwhile, he caused a gigantic power collapse on Androzani Major and managed to destroy one of the planet's most valuable resources.
* AndAnotherThing: Used for a KickTheDog moment; after pushing the President into an empty elevator shaft, Morgus announces that he's flying to Androzani Minor on a peace mission to end this horrible carnage. Oh, and he wants the lift maintenance engineer shot.
* AntiVillain: Sharaz Jek is an admitted mad terrorist who only wants to see Morgus dead, but compared to the other villains in his story he's almost a saint..
* AnyLastWords: The firing squad
-->'''General Chellak:''' Do you have any last declaration?
-->'''Doctor:''' Nothing special. We're innocent, we've had no trial, we've had no opportunity to defend ourselves; in short, this is a mockery of justice.
-->'''General Chellak:''' Do you have any last declaration?
-->'''Peri:''' [[GetItOverWith Just get on with it]].
* AsideComment: Morgus addresses the camera directly on occasion. This was a result of the actor misinterpreting the stage directions, but it recalls the Jacobean theatrical tradition of the AsideComment, and so gives the character an air of Shakespearean villainy.
** Also the Sixth Doctor for his "Change my dear, and it seems not a moment too soon."
* AsideGlance: Morgus occasionally addresses the camera.
* BadassBandolier: The gunrunners wear bandoliers of gas grenades.
* BadassBoast: "I'm not going to let you stop me now!" Doubly badass, as the scene subtly implies the Doctor is saying it to both Stotz (who's trying to retake control of the shuttle from him) and ''himself'', as his regeneration process seemingly begins.
* BadBoss: Stotz is awful to his gunrunner underlings, holding a knife to one's throat and almost force-feeds him a suicide pill.
* BastardlySpeech: CorruptCorporateExecutive Morgus uses PatrioticFervor slogans while [[WarForFunAndProfit plotting treason]] and preaching high-minded virtue while [[KickTheDog Kicking The Dog]].
* BastardUnderstudy: Morgus is overthrown by his secretary! Particularly ironic because Morgus suspects everyone ''but'' her of plotting against him, even when they're not.
* BBCQuarry: The surface of Androzani Minor.
* BeneathTheEarth
* BetweenMyLegs: One of the gunrunners stands menacingly over a resting Stotz to intimidate him. He's not impressed, and quickly turns the tables on him physically and psychologically.
* BigBad: Morgus is arguably the story's most irredeemable and prominent villain, but notably he never actually meets the Doctor face-to-face.
* BlackAndGreyMorality: The story is noted for being almost entirely bereft of likable characters other than the Doctor and Peri; the most sympathetic is Jek, and he's a psychopath.
* BlatantLies: The Doctor looks through the bars of their detention cell and sees the firing squad assembling outside.
-->'''Peri:''' Anything interesting?
-->'''Doctor:''' No. [[GallowsHumor Looks like a graveyard]].
** Played for HypocriticalHumor with Morgus, who uses PatrioticFervor slogans while plotting treason and [[BastardlySpeech preaching high-minded virtue]] while [[KickTheDog Kicking The Dog]]. Not to mention bringing up the mass unemployment, which he's causing.
* BondVillainStupidity: Justified -- Sharez desires the Doctor's intellectual stimulation as well as Peri's beauty, but makes it clear that he will kill the Doctor if he can't bend him to his will.
* BreakingTheFourthWall:
** Morgus repeatedly turns to the camera and gives exposition soliloquies. WordOfGod says that this wasn't intended ó the actor had misunderstood the stage directions in the script, but the director liked the effect it gave and told the actor to keep doing it, as it made the story similar to a classical theatre piece and played on the similarity of the plot to early-modern revenge tragedies.
** At the end of the story after the Doctor regenerates, this new incarnation of the Doctor speaks to the camera when he says the last half of the line "Change my dear, and it seems not a moment too soon."
* BridalCarry: A dying Peri is carryed by first Jek (in a VillainousBreakdown) and then the Doctor (back to the TARDIS).
* ChairReveal: We don't see Morgus until he turns to break the fourth wall.
-->'''Morgus:''' The spineless cretins!
* ChewingTheScenery: By the time Sharaz Jek is through, the entire set is covered with toothmarks!
* TheChewToy: Surprisingly, the Doctor. He gets poisoned, almost shot in the head by an android, nearly gets his arms pulled off, handcuffed, blindfolded, singed a bit, slapped by Sharaz Jek among other things, and then ''dies''.
* ChromosomeCasting: Apart from Peri, the only female character is Timmin. They're the only characters who survive.
* CliffHanger: The endings of Part One and Part Three are considered among the best in the show's history.
* CliffhangerCopout: The first episode ends with the Doctor and Peri geting shot, execution style, and falling down dead. The following episode resolves the conflict ten seconds in, when it is revealed that the executed parties were actually robot look-a-likes.
* ComingInHot
-->'''Doctor:''' Stotz, we'll be touching down in a couple of minutes, or more likely crashing down. ''(buckling up)'' You see I'm a bit out of practise with manual landings so if I were you, I'd find something firm to hang on to!
* ConvenientlyPlacedSharpThing: The Doctor is chained to the wall in the spaceship control cabin. He's able to break free of the wall, and finds a vertical glowing energy thingy he can use to cut the chain, through trying to do so while standing with your back to it is rather painful.
* ContinuityCavalcade: When the Fifth Doctor dies, he hallucinates all his companions (of that incarnation) gathering around encouraging him to regenerate. (And the Master encouraging him to give up and die.)
* ContinuityNod: [[Recap/DoctorWhoS21E5PlanetOfFire Speaking about the mud in the Androzanian landscape, Peri says it's "a change from lava"]].
* ConvectionSchmonvection: Averted; Jek's terrible injuries were caused by his taking shelter from a mud burst in a baking chamber. Stotz cuts a hole in the cockpit door to stop the Doctor, but the edges of the hole are too hot for him to reach through and open it.
* CorruptCorporateExecutive: Morgus is shown deliberately manipulating the supply of product to increase profits, and won't stop at sabotage or even murder to get his way. And that's just in the ordinary course of business, before getting to what he's up to on Androzani Minor.
-->'''Secretary:''' The world will be forever in your debt, Trau Morgus!
-->'''Morgus:''' Yes....quite so.
** What he's getting up to involves shutting down factories on one side of Androzani Major, arresting the people made jobless and homeless by this and having them moved to labor camps on the other that he just happens to own.
* CorruptPolitician: The President of the (equally corrupt) Presidium.
* CowTools: Sharaz Jek has lots of them, one of which he uses to kill Morgus.
* CrapsackWorld: This story consists entirely of insane and/or absolutely horrible people fighting each other to the death for entirely selfish reasons, with the Doctor and Peri helplessly caught in the crossfire and the Doctor dying as a result.
* CreepyMonotone: Morgus constantly speaks in a hushed, sullen tone that hardly ever fluctuates.
* CyanidePill: Mercenary gunrunner Stotz is confronted by one of his men demanding payment. Stotz forces him to the ground at knifepoint and takes out a pill.
--->'''Stotz:''' The boss gave me one of these. Ten seconds he said. Let's see if it works. ''(shoves it in the mook's mouth, who tries to swallow it whole but Stotz jams a fist over his throat)'' COME ON, YOU SLUT! BITE! BITE! BITE! ''(lets him go)'' Next time, it'll be for real.
* CyberCyclops / MechaMooks: Sharaz Jek's androids.
* DarkerAndEdgier: This story wouldn't have been out of place in Phillip Hinchcliffe's tenure. Creator/RobertHolmes felt that the Fifth Doctor's adventures had been too easy, so for his final story, he decided to put him through hell.
* DeadlyGas: Stotz is providing Sharaz Jek with gas weapons, among other things, which prove to be a major advantage over the army. Androids aren't affected by gas and the army's gas-suits are inefficient.
* DeathByMaterialism: Stotz and his gang follow Jek through the caves while he's apparently fetching spectrox for them, hoping to find where the spectrox is stored and raid it. However, Jek [[IKnowYouKnowIKnow expected this]] and led them to where the monster was. Two soldiers were killed.
-->'''Krelper:''' You tricked us into that!\\
'''Jek:''' No, you were led by your own cupidity. Greed, heedless of caution, lures many a man to his death.
** This proves Morgus final downfall, when he tries to steal Jek's entire supply of Spectrox (admittedly Morgus hadn't got much choice by that point, having lost all his power and money). He fails to realise that Jek hates him so much he'd give his own life to kill Morgus.
* DeathWorld: Androzani Minor features regular semi-volcanic mud bursts, is inhabited by a (admittedly rather unconvincing) carnivorous creature and is the native environment of a mineral which, in its raw state, will kill you within a few days if you so much as touch it. Not to mention you can get shot for being in the wrong place at the wrong time, as there's a rather brutal war going on.
* DecapitationPresentation: Sharez Jek wants only one thing to call off his war, the head of Morgus brought to him.
* {{Deconstruction}}: Can arguably be seen as one for the standard ''Doctor Who'' story formula, especially during the Fifth Doctor's era. The story starts off unassumingly with the Doctor believing this to just be another harmless adventure. As the story unfolds the Doctor tries all of his usual motions to get a foothold (smooth talking, appealing to better nature, trying to reason a compromise), only to have them all thrown back into his face.
* TheDeterminator:
** The Doctor breaks free of metal restraints, steals a spaceship, outruns armed and angry mercenaries, climbs deep into caves with no oxygen and back, and carries Peri to the TARDIS ''while in the '''paralysis''' stage of his disease''. And all of this while (apparently) holding back the regeneration process.
** Also Sharaz Jek during the final confrontation.
-->"Morgus! You think bullets could stop me now?!" (They don't)
* DiedInYourArmsTonight: Sharaz Jek dies in the arms of one of his androids; The Doctor dies in Peri's arms.
* DistressedDude: Like his Third and Fourth incarnations, the Fifth Doctor gets kidnapped in this story, and chained and blindfolded.
* DownerEnding: The Fifth Doctor and most of the cast ends up dead, but to cap it all of as he dies the last image to go through the Doctor's head is The Master looming over him, cackling triumphantly.
** An AlternateCharacterInterpretation raised by the novelisation is that the Doctor actually is on the verge of final, irreversible death until he sees the Master, which is what inspires him to regenerate and live -- the refusal to let the Master (and by extension his enemies / the evil he opposes in general) have the last laugh.
* DoNotTauntCthulhu: The Doctor snarks every powerful, gun-toting and/or homicidal character he comes across, but Sharez Jek makes it clear he doesn't appreciate this.
-->"Your sense of humor will be the death of you, Doctor. [[ImpliedDeathThreat Probably quite soon]]."
* DramaticUnmask: Sharaz Jek unmasks himself during the final confrontation with Morgus, to show Morgus (and the audience) the extent of his injuries.
* DyingMomentOfAwesome: This whole story is one for the Fifth Doctor.
* ElaborateUndergroundBase: Just how did Sharaz Jek furnish his place, anyway?
* ElevatorFailure: Morgus shoves the President down the empty elevator shaft of his private lift.
* EstablishingCharacterMoment:
-->'''The Sixth Doctor:''' Three Iís in one breath? Makes you sound a rather egotistical young lady.
* EvenEvilHasStandards
** The corrupt President is becoming disenchanted with Morgus and makes little effort to hide it, leaving Morgus to believe (incorrectly) that the President is moving against him.
** Jek acts rather guilty when Peri asks where the Doctor has got to, having let Stotz take him away. He quickly reverts to [[NeverMyFault blaming it all on Morgus though]].
* EvilIsHammy: Sharaz Jek and Morgus are almost Shakespearean in their furious ranting and scheming asides, respectively.
* EvilLaugh: Sharez Jek and the Master naturally, but the imprisoned Salateen gives a disturbing laugh when informing the Doctor and Peri that they're dying of spetrox poisoning.
-->'''Salateen:''' Oh I'm sorry, you probably can't see the funny side of it.
* EvilVersusEvil: The only relatively sane and decent character is Chellak, and even he's willing to send a guy to certain death just to cover up an embarrassment.
* FateWorseThanDeath:
** Sharaz Jek plans to keep Peri with him forever. The Doctor assumes this means it will seem like forever, but Jek means it literally, thanks to his control of the only source of spectrox.
** According to actor Creator/PeterDavison, death would be preferable to turning into Colin Baker. We assume he's joking, given the two actors are friends.
* FindTheCure: The Doctor's half of the plot, from the point when he discovers that he and Peri are dying of spectrox poisoning. Fortunately, there is a cure, it's just very hard to get at.
* FiringInTheAirALot: The soldiers who hear their colleague scream as the monster kills him run back shooting their guns in the air. Given that it's difficult to kill, they may have been hoping to scare it off.
* FloatingAdviceReminder: As the Doctor lies dying, his companions' heads float around encouraging him to regenerate... and then the Master's head shows up and tells him to give up and die:
-->'''Tegan:''' ''"What was it you always told me Doctor? "Brave heart?" You'll survive, Doctor."''
-->'''Turlough:''' ''"You must survive. Too many of your enemies would delight in your death, Doctor."''
-->'''Kamelion:''' ''"Turlough speaks the truth, Doctor."''
-->'''Nyssa:''' ''"You're needed. You mustn't die, Doctor."''
-->'''Adric:''' ''"You know that, Doctor!"''
-->'''The Doctor:''' ''"Adric?"''
-->'''The Master:''' ''"No my dear Doctor, you must die! Die Doctor! DIE DOCTOR!"''
* {{Foreshadowing}}:
** The effect used for the Doctor's distorted vision near the end of Part Three is the same effect used for his regeneration at the end of the serial, with the former appearing to subtly foreshadow the latter. The use of this effect in Part 3 was intended by the director to indicate the onset of the Doctor's regeneration, which means that the Doctor is holding off his regeneration for the entirety of Part Four.
** Shortly before he regenerates, the Doctor notes that it "feels different this time." Perhaps a warning of a regeneration about to go awry and foist upon us the horrors of Six's characterization?
* FutureImperfect
-->'''Morgus:''' As they used to say on Earth, every cloud has a strontium lining.
* GadgeteerGenius: For once, the Doctor's not the only one - Sharaz Jek has his android creations.
* GettingCrapPastTheRadar: The infamous moment when viewers get a ''very'' strong view of Peri's cleavage right before the Fifth Doctor regenerates, which Creator/PeterDavison even recalls was distracting during the day they filmed his final scene.
* HelmetsAreHardlyHeroic: Averted; all the soldiers wear mining helmets.
* HeroicSacrifice: The Doctor stumbles and spills half of the antidote as he's about to enter the TARDIS, so he gives it to Peri.
* HolographicTerminal: The communicator in Morgus' office, in a creative variation on the usual VideoPhone.
* {{Homage}}: The whole story is one to ''Literature/{{Dune}}'' (apart from that Jek, who's got an obvious [[Franchise/ThePhantomOfTheOpera Phantom of the Opera]] thing going on). Androzani is an export platform for a life-extending mineral, currently being feuded over by the head of the mining conglomerate (read: Baron Harkkonen) and President (i.e. Padishah Emperor). The color-coded Army uniforms seem to be inspired by ''Franchise/StarTrek''.
* HowTheMightyHaveFallen: Jek gives a long rant on the subject, and after Morgus loses all his power and assets Stotz makes a point of reminding him that he's just a man with a gun now.
* HumanAliens: Averted with the people of the Androzani system, who are descendants of human colonists. However, utilised in-story with the Doctor's presence, as his different biology is enough to fool the guard androids to hesitate attacking him (as they're programmed to guard against humans).
* HumanShield: Salateen uses Peri as one while shooting at an android; because she's wearing one of the belt buckles that send a signal cancelling the android's kill command.
* HumiliationConga: Morgus loses all his wealth and power during the final episode, in quick succession.
* HypercompetentSidekick: Subverted with General Chellak's aide Salateen -- the reason he's so efficient and cold-blooded is because he's one of Sharaz Jek's androids. That said, the real Salateen is still a very savvy lieutenant.
* HypocriticalHumor: The Doctor complains of Jek being a raving egotist, because he claimed the Doctor's mind was almost equal to his own.
* IconicItem: We finally get an explanation for why the Doctor wears a stick of celery.
* IHaveYouNowMyPretty: Sharaz Jek's intentions towards Peri are... not benign. And, although [[GettingCrapPastTheRadar it's not explicitly stated]], this does not go unnoticed by either Peri or the Doctor; in every scene the three characters are in together, [[IWillProtectHer the Doctor makes a point of putting himself between Peri and Jek]].
* IRejectYourReality: Morgus is irrevocably convinced that the Doctor and Peri are government agents trying to topple his schemes. Granted, there is little evidence to the contrary and the Doctor is most definitely a [[SpannerInTheWorks spanner in his works]], but this incorrect assumption ultimately leads to his downfall.
* IllKillYou: The Doctor isn't impressed -- as he points out to Stotz, he's dying anyway.
* ImmuneToBullets: The Magma Creature isn't fazed by bullets when it attacks the soldiers and the gunrunners, although it's dead by the time the Doctor comes across it again.
* ImproperlyPlacedFirearms: [[CoolGun Ingrams]] InSpace!
* IncomingHam: The Sixth Doctor introduces himself to the world with some good old-fashioned ''[[DeadpanSnarker snark]]''!
--> '''Peri:''' ...Doctor?
--> '''Sixth Doctor:''' You were expecting someone else?
* InfraredXrayCamera: Salateen hides Peri in the general's private quarters while the general talks to his android replicant. Unfortunately the android can see through walls.
* InstantDeathBullet: Mostly played straight but averted by Sharaz Jek, who survives on determination long enough to settle Morgus before succumbing to his injures.
* InstantSedation: Used by Sharaz Jek when he abducts Peri from Chellak's quarters.
* InTheHood: The Doctor and Peri have their faces covered by the Red Cloth before execution. As a result, only one man realises they've just shot two android replicants, and he's quickly reassigned to a dangerous mission by the General to cover for this cock-up.
* ItsTheOnlyWay: The Doctor has an idea that Jek's android guards won't kill anything that's not human. He tests this theory by ''opening the door and waiting to see if they shoot him''.
* IWasQuiteTheLooker: PlayedForDrama with Jek, who goes into various HowTheMightyHaveFallen rants.
* IWillProtectHer: This is essentially the Doctor's key motivation for the bulk of the story -- he's not interested in the civil war or the smuggling or whatever, he just wants to get Peri cured, [[IHaveYouNowMyPretty out of Sharaz Jek's hands]] and off the planet ASAP.
* IWillTearYourArmsOff: Sharaz Jek threatens to have the Doctor's arms slowly ripped out by androids if he doesn't tell him what he wants to know. Unusually for this trope, the androids start making good on this threat before the Doctor gives in.
* KangarooCourt: The Doctor and Peri don't even get that. Once Morgus confirms the 'captured gunrunners' are not Stotz and his gang, he orders them shot. When General Chellak protests that they could provide valuable information, Morgus overrules him.
* KillEmAll: Literally, only two characters survive this story - Peri and a single secondary character. The android copy of Salateen may have survived as well, although it's debatable whether it counts. At least the Doctor [[TheNthDoctor could get better]].
** There's also the man Morgus sends out to sabotage something, who's never seen again, though knowing Morgus he was probably killed to tie up loose ends. The [[Literature/DoctorWhoNovelisations novelisation]] does indeed make a point of having Morgus make an order to have that guy taken care of.
** Even the random monster is dead by the end.
* LackOfEmpathy: Morgus leaves his business partner for dead, deliberately causes "accidents" that kill his workers and personally murders his superior, all for the pursuit of profit. It is implied that he only saw Sharaz Jek as an obstacle and didn't quite understand just how much Jek hates him. He believed that Jek would back down from a gun pointed at him, or that a bullet would slow him down. [[TakingYouWithMe He]] [[UnstoppableRage was]] [[TheDeterminator very]] [[ThePowerOfHate wrong]].
* LargeHam: Sharak Jek is one of the largest hams in ''Doctor Who'' history, and is all the more memorable for it.
* LetsGetDangerous: It takes the Doctor a while to accept that these people simply cannot be reasoned with. Once that happens, he thrusts himself into action and nothing can stand in his way.
* LuredIntoATrap: Jek isn't bothered when Salateen escapes with the device that tells the androids not to fire on him, as he simply programs his remaining devices to work on a different frequency. Unfortunately Salateen also knows the location of his base, and the army overwhelms his androids by sheer force of numbers.
* TheMadHatter:
-->'''Sharaz Jek:''' You think I'm mad?\\
'''Peri:''' N-n-no.\\
'''Sharaz Jek:''' I ''am'' mad.
* MadScientist: Jek -- even his enemies acknowledge the brilliance of his androids.
* MagicAntidote: Peri goes from death's door to practically back to normal within seconds of being given the antidote.
* MakeItLookLikeAnAccident:
-->'''Morgus''': Krau Timmin, the most appalling thing has happened. His Excellency...\\
'''Timmin''': Not the President?\\
'''Morgus''': Yes, it was all over in a second. I had no time to stop him. This is a tragic loss to the world.\\
'''Timmin''': It's dreadful, sir. And that it should have happened in ''this'' building.\\
'''Morgus''': Yes, yes, I am deeply distressed, Krau Timmin.\\
'''Timmin''': Naturally you must be, sir.\\
'''Morgus''': Still, it could have been worse.\\
'''Timmin''': In what way, Trau Morgus?\\
'''Morgus''': It could have been me.
* MalevolentMaskedMan: Sharaz Jek wears a head-covering mask to conceal his disfigurement from the mud geyser.
* MaleGaze: The Doctor's moving death scene is [[DistractedByTheSexy somewhat undermined by the excellent view the audience have]] of Peri's cleavage. Peter Davison once remarked that it it's all he can remember about filming the scene.
* MenAreTheExpendableGender: ''Everyone shown onscreen'' in the serial dies ([[TheNthDoctor The Doctor]], [[GoodThingYouCanHeal of course, gets better]]) with the exception of Peri and Morgus' secretary. They are, not coincidentally, the two only female characters in the serial.
* MiscarriageOfJustice: The Doctor and Peri are found standing among a stash of weaponry being smuggled to Sharaz Jek, so are hastily sentenced to death by firing squad. Chellak acknowledges they may be innocent, but has to carry out his orders.
* MistakenForSpies: The Doctor's unexplained presence on Androzani Minor leads Morgus to assume he's a spy for the President, leading to several fatal mistakes on Morgus' part.
* MyGodWhatHaveIDone: Sharaz Jek becomes remorseful when all of his androids are destroyed in the final skirmish and he learns that Peri is dying of Spectrox Toxaemia, as he could have sent an android into the dangerous caves to find the antidote.
* MyGreatestSecondChance: The Doctor and his companion, Peri, are exposed to deadly radiation early on in the story, and the Doctor spends the rest of it giving his all to save Peri. Having been unable to save Adric back in "[[Recap/DoctorWhoS19E6Earthshock Earthshock]]", he felt even his own life was not worth sacrificing Peri's, and after spending four episodes looking for the antidote and escaping more imminent death, he gave the only dose that survived to his companion. Even his last thought, "Adric?", indicates he felt this was a "second chance" of sorts.
* NamesToRunAwayFromReallyFast: Morgus.
* NeverMyFault: Sharaz Jek blames Morgus for everything bad that happens to him.
* NobleDemon: Sharaz Jek treats his prisoners like guests and doesn't do harm to people who haven't wronged him first.
* NonIndicativeTitle: Despite the title, the Doctor notes that the caves are in fact blowholes.
* NoodleIncident: For the entirety of his tenure, the Fifth Doctor wears a stalk of celery on his left lapel, pinning it on in "[[Recap/DoctorWhoS19E1Castrovalva Castrovalva]]". In his final serial, we learn this incarnation suffers allergies from Praxis gasses in star systems. If he comes in range of these gases, the celery turns purple and he eats its to (presumably) act as an immunity booster to the allergens. However, we never see this happen on screen, because this was a last minute explanation written in to justify his habit of pinning the celery to his clothing.
* NoBloodForPhlebotinum: The conflict over spectrox, "the most valuable substance in the universe".
* NoSeatBelts: Averted with the Doctor's crashlanding, enabling him to recover and flee before Stotz and his men can get to their feet.
* NotHyperbole: When Jek says he wants Morgus' head "congealed in its own vile juice" that's not a metaphor.
* NotQuiteDead
* NotThatKindOfDoctor: Averted. Sharaz used to be a doctor, before everything that happened to him.
* NothingIsScarier: YMMV, but Sharaz Jek's scarred face is significantly more horrifying when we only see people's reaction to it. Unfortunately we do get a direct look in the end.
* OOCIsSeriousBusiness: The Fifth Doctor indulges in some Fourth Doctor-style banter with his captors. The key difference here is that, unlike Four, Five isn't in total control -- he's [[StepfordSnarker sweating under the collar]] and playing a brinkmanship game, desperate not to get everyone killed.
* OneManArmy: In a sense. Jek is only one man, but his android army is sufficient enough to shunt his drug war into a stalemate.
* OurGraphicsWillSuckInTheFuture: The graphics for Sharaz Jek's computer are generated by a BBC Micro.
* PapaWolf: The Doctor ''will'' save Peri, no matter what.
* PeopleInRubberSuits: The ridiculously fake monster, which as usual is [[SpecialEffectsFailure overlit instead of being kept in shadow]].
* ThePowerOfHate: When Sharaz Jek finally comes face-to-face with Morgus again, his hatred is so immense that [[UnstoppableRage he walks through a hail of bullets to kill him with his bare hands]].
* ProperlyParanoid: Yes, there was indeed a government agent trying to expose Morgus. It just wasn't the Doctor, or anyone else he suspected for that matter.
* RedOniBlueOni: Sharaz Jek is Red to Morgus' Blue. Jek is prone to violent raving, Morgus has a LackOfEmpathy.
* RedemptionEqualsDeath: Sharaz Jek starts showing a better side to his nature when Peri enters the final stage of her illness, nursing her and offering the Doctor as much help as he can to obtain the cure. He's dead by the end of the episode.
* RedShirt: The army troopers. Their uniforms are even coloured like ''Series/StarTrek'' -- Yellow for the General, blue for his aide, red for the enlisted men.
* RidiculouslyHumanRobots: Jek's robotic doubles are amazingly articulate when it comes to expressing emotions. The only real give away is that they don't blink as much as a human would.
* RightForTheWrongReasons: Yes, Morgus is a diabolical bastard who must be brought down. Jek's only motivation for wanting to kill him is for the sake of his own selfish revenge.
* RoaringRampageOfRevenge: Sharaz Jek has started the whole war simply to get revenge on Morgus.
* RocksFallEveryoneDies: A massive series of mud bursts kills everyone in the caves who isn't already dead, including the entire army.
* SecretUndergroundPassage: Jek has secret passages to the cells where Chellak is holding Peri and the Doctor. Justified as he used to own the place (it's a former spectrox refinery which the army took on their first assault; presumably Jek installed the hidden cameras and tunnels in advance so he'd know everything the army was up to).
* SecurityCling: Peri throws herself into the Doctor's arms with a terrified squeal in response to Jek SuddenlyShouting.
* SesquipedalianLoquaciousness: Even though Morgus constantly talks in a sullen tone, he has a very good vocabulary and knows exactly how to use it.
* ShootTheShaggyDog: While the Doctor manages to save Peri, the rest of Androzani Major and Minor go completely to hell because of a chain of events that was started by the Doctor simply being there and ended with every main character dying pointlessly. The entirety of these places were so riddled with corruption that it just took one thing to make everything collapse. Particular examples of this hopelessness include Stotz killing the rest of his crew and Sharaz Jek, moments after getting the revenge that he'd started the whole war that the plot centered around over, getting shot in the back.
* SightedGunsAreLowTech / KineticWeaponsAreJustBetter: Lots of shooting modified Ingrams and Sten guns from the hip.
* SolidGoldPoop: The highly valuable life-extending drug spectrox is made from something produced by the bats dwelling in the titular caves. The exact nature of the substance is never explained; however, antidote to spectrox toxaemia is the milk of the queen bat, which the Doctor uses to save Peri's life at the cost of his own. His HeroicSacrifice takes on a bit of fridge hilarity when you realise that the Fifth Doctor's last act was to milk a bat.
* SpannerInTheWorks: The Doctor's role in the story is limited to attempting to get him and Peri out alive. His mere presence, however, inadvertently causes the entire messed-up Androzani society to implode. The Doctor brings down a corrupt government and ends a bloody civil war ''by accident''.
* SherlockScan: The Doctor analyses the markings on the planet's surface and concludes that an interplanetary spacecraft landed to unload some cargo.
* ShotAtDawn: Death under the Red Cloth (not that they bother waiting til dawn, being underground). This is the CliffHanger of Part One.
* ShoutOut:
** The Doctor seeing his former companions as he regenerates was probably inspired by ''Series/IClaudius''.
** The sound effect in the regeneration was inspired by "A Day in the Life" by Music/TheBeatles.
* SinisterSurveillance: Jek first spies Peri via the cameras he's got hidden in General Chellak's headquarters.
* SpiceOfLife: Spectrox
* StalkerWithACrush: Sharaz Jek quite clearly has the creepy kind of hots for Peri, doing things like chloroforming her, stroking her face while she's unconscious, and carrying her around in his arms (again, unconscious) while whispering "so beautiful...so beautiful...". The fact that he also dresses entirely in black leather really doesn't help.
* TheStarscream: Timmin, who is the only person Morgus seems to trust until she gleefully deposes him and takes his place. There's no reason to think that things will be better with her in charge.
* TragicVillain: Sharaz Jek is a cruel, possessive terrorist, but only because of Morgus' betrayal. He goes into a lengthy villain monologue to Peri over how he used to be an optimist, but the trauma from the incident caused him to see the ugliness in everyone. He wants to keep Peri for himself because she's the only light in the darkness for him.
* UriahGambit: Ensign Cas is sent on a deep penetration mission as the only witness to Chellak cocking up the execution of the Doctor and Peri. "Very few return."
* VillainWithGoodPublicity: Morgus.
* WarForFunAndProfit: The war keeps the price of spectrox up, and Morgus can access the only source by secretly selling guns to Sharez Jek, who is unaware of his participation.
* WhamLine: "Ah, Timmin. I would like you to-- ''Why are you sitting at my desk?''"
* WoobieDestroyerOfWorlds: The Doctor and Sharaz Jek both qualify.
* TheXOfY
* YouHaveOutlivedYourUsefulness: Morgus tried to kill Sharez Jek by sabotaging his mud burst detectors rather than share the profits with him. He plans to steal the spectrox supply with the help of Stotz, who says his mooks will also expect a cut. Morgus acknowledges that the mooks can carry more out, leaving more to be split "between us". Stotz adds, "You mean...us."
** When those mooks refuse to join the raid on Jek's headquarters, Stotz comes back and kills them. He then points out to Morgus why it would be stupid to try the same thing with him.
* ZergRush: Even though he leads the army into a trap, Sharaz Jek's android army is overwhelmed by sheer weight of numbers.
