[[folder:House Atreides and Supporters]]

The good guys. Mostly. [[spoiler: Seem to be descendants of [[ClassicalMythology the Atreides and Agamemmnon]], and their ancestor's curse still seems to hold sway over them.]]

!Duke Leto Atreides
* BetterToDieThanBeKilled: Only bites the poison capsule in his mouth once he sees there's no getting out of this one.
* BigGood
* TheChainsOfCommanding: Why he can't marry Jessica. Staying eligible is the one reason the other Houses show him goodwill.
* DeadManWalking
* DefiantToTheEnd: With Yueh and the Baron.
* AFatherToHisMen: He abandons a full load of spice in the interest of saving every last worker.
* GildedCage: Arrakis, and on a smaller scale the Governor's mansion (which is encased with shields).
* GuileHero: He's not really coldblooded enough to be TheChessmaster; that's Hawat's job. But he knows how to scheme and plot reasonably well.
* LikeASonToMe: The Emperor himself confided that he wished to have Leto for a son, and regrets that "[[TheResenter political necessities]]" obliged him to screw him over.
* PapaWolf: ''They have tried to murder my son!''
* ThePatriarch
* PoorCommunicationKills: Having a Bene Gesserit for a lover isn't much use when you think she's a spy. The Harkonnens expertly manipulated everybody into not talking to the Duke. He in turn is trying to draw the enemy out, but it only makes matters worse.
* RealMenHateAffection: Adding to Leto's problems, Jessica is chafing under his frosty persona. Leto desperately wants to be affectionate with her, but it would be political suicide. She's not a Duchess, just a concubine.
* ReasonableAuthorityFigure
* [[RoyalsWhoActuallyDoSomething Royal Who Actually Does Something]]: Almost immediately after arriving on Arrakis, he takes an active role in building up the spice mining industry and organizing the management of Dune.
* SacrificialLion
* TakingYouWithMe: [[spoiler:He attempted to kill Baron Harkonnen using a poison gas in one of his molars that would take out everyone in the room, including himself. Unfortunately he doesn't quite get the clean sweep, and that's as bad as not trying.]]
* TrapIsTheOnlyOption: Though outwardly a gift to House Atreides, Leto fully realizes that Arrakis is a trap. The Emperor feels threatened by Leto's popularity, and conspires to crush him.
* UnwittingPawn: Being lured into taking the title to Arrakis instead of [[NobleFugitive going into exile]]. [[AlternativeCharacterInterpretation Alternatively]], his seeming mistake was a success.

!Lady Jessica Atreides

* AbusiveParents: Reverend Mother Mohiam was a mother figure to Jessica during her childhood [[spoiler:and was secretly her biological mother.]] However, Mohiam speaks cruelly to Jessica, and when Paul protests, Mohiam states that she used Jessica as her servant during childhood. It's implied that she's treated Jessica with a mixture of love and cruelty all her life.
* AlwaysSomeoneBetter: Paul, who one-ups his mother's hyper-awareness. ("''She's so slow.''")
* {{Badass}}: Oh yes. She manages to overpower a ''Fremen sietch leader'' in hand-to-hand combat.
** BadassPrincess
* BeneathTheMask: Type B: hidden powers.
* BewareTheNiceOnes: Even if she is one of the kindest, most humane people among House Atreides, she is still a Bene Gesserit-- with all the power and skill that implies.
* CompellingVoice: A Bene Gesserit power, which she also taught Paul.
* FallenPrincess
* [[HappilyMarried Happily Sort-of Married]]: Both she and Leto consider themselves married. The only reason they don't formalize it is to keep the possibility of an alliance with other Houses open.
* HotConsort: Jessica is ''officially'' a [[SexSlave concubine]] for the purpose of diplomatic convenience, but in practice she is running the whole show.
* LadyOfWar
* MamaBear: She is quite protective of Paul, and will do anything to protect him.
* MindManipulation: Used rarely, primarily in self-defense or in a demonstration of her secret powers when such is necessary.
* MinoredInAsskicking: She may major in political manipulation, but she can take down ''any'' Fremen-- who are the guys that easily beat up the [[EliteMooks Sardaukar]]. In fact she's so good that when he first meets her, Stilgar is worried that in the Fremen's AsskickingEqualsAuthority society, she may choose to become the leader.
* RebelliousPrincess: Rebelling against the Bene Gesserit, that is.
* TheVamp: The Bene Gesserit specifically bred her to be one. However, Jessica hasn't used her wiles on Leto as she could have.

!Paul Atreides

* TheAce: partly by nature, with a very large slice of nurture.
* AGodIAmNot
* TheAtoner: By the end of ''Dune Messiah'' and in ''Children of Dune''.
* AwesomenessByAnalysis: He was good before he got to Arrakis. However once the spice kicked, in his analytical prowess [[TookALevelInBadass Took A Level In God-like Prescience]].
* BadassPreacher: As "the Preacher."
* BlessedWithSuck: While at first, he seems like a near-perfect hero destined for great and noble deeds, his ultimate fate is as inglorious and miserable as it gets.
* BreakTheCutie: He's introduced as a precociously intelligent fifteen year old with loving parents and devoted mentors. He is then psychologically tortured, uprooted from his home, narrowly survives an assasaination attempt, sees everyone he knows massacred (except his mother) and is forced to fight a grown man to the death. This is the first half of the first book. Things do not get better.
* CameBackStrong: He almost dies when he drinks the Water of Life, and when he wakes up he is the Kwisatz Haderach.
* TheChosenOne: Unfortunately...
** ItSucksToBeTheChosenOne
* CombatClairvoyance
* CompellingVoice: Like the Bene Gesserit.
* DamnYouMuscleMemory: He's been trained all his life to circumvent personal shields. Fremen have no use for shields.
* DarkMessiah: He wasn't really a MessianicArchetype to begin with, but kept being persuaded about it by people full of wishful thinking to the point where [[BecomingTheMask he started believing in being]] the embodiment of an idea he previously scoffed at.
* DreamingOfThingsToCome
* [[EvenBadMenLoveTheirMamas Even Badass Demigod Warlords Love Their Mamas]]: Just stay away from Jessica.
* EyeScream: He gets blinded by an atomic weapon. He can continue to see, sort of.
* FallenHero: By the time of ''Dune Messiah''. And he's [[MyGodWhatHaveIDone fully aware of it]].
* FluffyTheTerrible: His Fremen name means "The Mouse." The Harkonnens weren't exactly quaking in their boots at first.
* GalacticConqueror: He conquered the Imperium and became its new ruler.
* GenerationXerox: Paul ends up keeping Chani on as his "concubine", precisely as his father did.
* GoingNative: After the fall of the house of Atreides, he and Jessica find refuge among the Fremen and quickly assimilate into their culture.
* GoneHorriblyRight: The Bene Gesserit wanted a man with the perfect genes, so they could control the course of human history through him. Instead, they ended up unleashing a massive uncontrollable wave of religious hysteria across the galaxy, changing human civilization forever.
* IHaveManyNames: Paul Atreides, Lisan-al-Gaib, Usul, Muad'dib, [[spoiler:The Preacher]].
* IJustWantToBeNormal: What he would like to be after becoming the all-purpose political and religious figurehead messiah of humanity.
* [[spoiler:KilledOffForReal: He dies in ''Children of Dune'', stabbed to death by one of the priests who worship him as a god.]]
* LonelyAtTheTop: His mother, sister and Chani are probably the only three people who know the man, instead of the semi-divine messiah.
* MagneticHero: Why the Fremen decide to follow him.
* MightyWhitey: Justified in-universe in that the legends which assure his ascendancy were deliberately planted in the local culture, ages ago.
* OlderThanTheyLook: He's described in the books as looking very childlike as a teenager, which works to his advantage as it often causes his enemies to fatally underestimate him.
* PapaWolf: The death of his first son extinguishes any thoughts of mercy he had towards the Harkonnens.
* RoaringRampageOfRevenge: The Harkonnens, with the Emperor's backing, nearly exterminated his entire House. Who wouldn't be angry after that?
* RefusedTheCall: Ultimately he rejects the Golden Path.
* SorcererKing: Though he might be a SorcerousOverlord instead.
* StopWorshippingMe: Since the events portrayed in ''Dune Messiah'', he laments that the strong and independent people he had come to love as his own have become swept up in the religious fervor of the Jihad.
* WarriorPoet[=/=]CulturedWarrior
* WarriorPrince: He's the heir of the house of Atreides in addition to being a formidable warrior.
* WoobieDestroyerOfWorlds: BecauseDestinySaysSo.
* YouCantFightFate: And he can sense it constantly. Paul makes several attempts to avert the Jihad; thanks to his efforts, he can say with satisfaction that the fremen 'only' killed [[AMillionIsAStatistic sixty billion people]].
* YoungConqueror
* [[spoiler:ZenSurvivor: A "living in secrecy version"]] in ''Children of Dune''.

!GodEmperor Leto Atreides II
The son and heir of Paul. Perhaps an even more powerful psychic than his father.

* AchillesHeel: [[spoiler:[[KillItWithWater Water]]]], in large amounts.
* AGodAmI
* [[spoiler:AndIMustScream: His awareness supposedly exists in each of the sandtrout and sandworms produced from his body. In his words, he is a pearl of awareness locked in an endless dream.]]
* AntiHero: Leto wants to help humanity but the way he does it is pretty brutal.
* AntiVillain: One could
* ArcWords: "The Golden Path."
* AristocratsAreEvil: The truth is actualy much more complicated that that.
* BodyguardBabes: He created the Fish Speakers to be his bodyguards and enforcers, after the scattering they became the Honored Matres.
* BodyHorror
* BrotherSisterTeam: With Ghanima.
* TheChessmaster
* TheChosenOne
* CombatClairvoyance
* [[CreepyTwins Creepy Twin]]
* DarkMessiah: He intends to save mankind from the "Typhoon Conflict" by imposing a 3000-year rule of despotism, followed by a sundering of mankind.
* DeadGuyJunior: [[spoiler:The second one, no less.]]
* DreamingOfThingsToCome
* TheEmperor
* EmperorScientist
* EvenEvilHasLovedOnes: He's devoted to his twin sister and loves Hwe.
* FoeTossingCharge: At the climax of ''Children of Dune'', Leto becomes strong enough to knock aside fully=armed combat troopers.
* GambitRoulette: His entire plan for saving mankind.
* GeneticMemory
* GodEmperor: The first of the two standard [[TropeCodifier Trope Codifiers]]. Also possibly the UrExample of the construct-title of "God-Emperor", at least in the English language.
* HolyChild: As a kid, along with his twin sister Ghanima.
* LastOfHisKind: By the time of ''Heretics'' and ''Chapterhouse'', his consciousness lives on in the last of the [[SandWorm sandworms]].
* LivingLieDetector
* LonelyAtTheTop: After his metamorphosis, Leto begins to grow apart from the very humans he is trying to save.
* LongGame
* MixAndMatchCritters: He becomes a human-SandWorm combination. One cover for ''God-Emperor of Dune'' depicts him as a SandWorm with a human face nestled in its mouth.
* MonochromaticEyes / TechnicolorEyes
* [[spoiler:MyDeathIsJustTheBeginning / HeroicSacrifice]]
* NecessarilyEvil
* [[spoiler:NotQuiteDead]]
* OmniscientMoralityLicense
* OrwellianEditor: Being a Kwisatz Haderach, has full access to his masculine and feminine genetic memory which stretches from about the year 100,000 back the beginning of human awareness. What does he do with it? He has historians burned alive for misconstruing the facts that he has personal access to. Of course, this was partly mystique-building, as he secretly rendered them unconscious first.
* PrescienceIsPredictable: Leto makes a few statements towards this end.
* PsychicPowers
* [[Really700YearsOld Really 3,500 Years Old]]
* RoyalsWhoActuallyDoSomething
* SilentScapegoat: Even the Bene Gesserit, thousands of years after [[spoiler:Leto sacrifices himself]], don't realize just what it was he was trying to accomplish.
* SorcererKing: See his father's entry. How "good" they are is debatable, considering how many billions died during the jihads of Paul's Fremen and how Leto played tyrant in order to get people to leave the stagnant core worlds and scatter throughout the universe. They have the ability of [[{{Seer}} prescience]] and conscious control over their bodies to an [[MasterOfYourDomain improbable level]]. And of course Leto II merged with a sandworm and became the TropeNamer for GodEmperor.
* [[spoiler:ThanatosGambit]]
* TwoBeingsOneBody: With sandtrout.
* {{Ubermensch}}
* [[WiseBeyondTheirYears Wise Beyond His Years]]

!Ghanima Atreides
The daughter of Paul and Chani and twin sister of Leto II.

* BrotherSisterTeam: With Leto II.
* CreepyChild: She and her brother have the demeanor, skills, and memories of adults, making them very unsettling.
* [[CreepyTwins Creepy Twin]]
* GeneticMemory: She can access the memories of her female ancestors.
* HolyChild: Along with her brother.

!Alia Atreides
Paul's younger sister. Due to Jessica taking the Water of Life while pregnant with her, Alia is born with the memories of all her female line ancestors.

* [[spoiler: BigBad: For Children of Dune.]]
* CreepyChild: She has the skills of a Reverend Mother and all the memories of ancestors who came before her, making her decidedly unchildlike.
* IJustWantToBeNormal: She has her moments in ''Dune Messiah''.
* [[spoiler: TragicVillain]]
* WoobieDestroyerOfWorlds

!Thufir Hawat
Leto's right hand man and chief adviser.

* TheChessmaster
* CoolAndUnusualPunishment: In the 1984 film, he is required to milk a cat for the antidote to the poison he has been administered by the Harkonnens.
* TheConsigliere: To the Atreides.
* OldRetainer
* TheSpock: A Mentat of no small skill.
* TheSpymaster: As Master of Assassins to House Atreides.
* TheStoic

!Dr. Wellington Yueh
The personal physician to Duke Atreides.

* BeneathSuspicion: Due to his mental conditioning that should have made it impossible for him to harm others.
* TheCommiesMadeMeDoIt
* DoubleAgent
* {{Determinator}}: Yueh manages to stay alive long enough to give Baron Harkonnen a few last words before falling.
* IHaveYourWife : What led to his agreement to betray the Atreides.
* LoveMakesYouCrazy: He betrays a man he genuinely admires to one he utterly despises. And what's more, he knows that Baron Harkonnen has all but certainly murdered his wife. However, see The Power of Love below...
* TheMedic: In addition to the usual trappings of the trope, he has undergone conditioning designed to make it impossible for him to harm others.
* TheMole: The in-universe equivalent to Judas Iscariot. He doesn't relish the prospect of being remembered as a notorious traitor.
* ThePowerOfLove: A very dark example. In the Duniverse, doctors of the Suk School undergo mental conditioning so they really can do no harm, but Yueh's feelings for his wife were so strong it allowed him to overcome it. It's left open whether this is really due to love or the fact that his wife was a Bene Gesserit and [[CharmPerson the whammy that they habitually put on everybody the come in contact with]] was just stronger than the one he got from the Suk School.
* TakingYouWithMe: Yueh is unsure of whether his wife is alive, but plans to take out the Baron in either case.
* TragicVillain

!Gurney Halleck
An Atreides retainer and one of Paul's teachers.

* BadassGrandpa
* BadassNormal: In a universe of super-powered lordlings and hardened desert fighters, Gurney stands out for being none of those.
* CoolOldGuy
* GoodScarsEvilScars : His scar was made by an inkvine whip used by Harkonnen slavers. He's not evil at all, the scar is just a reminder of how much he hates the Harkonnens.
* IOweYouMyLife: The Atreides rescued him from a Harkonnen slave pit.
* TheObiWan : To Paul, but not overtly.
* OldRetainer
* UndyingLoyalty: He serves the Atreides with all his heart.
* WarriorPoet / CulturedWarrior: As Duncan Idaho describes him in ''Heretics'':
--> "Ahhhh, Gurney! He could kill you while singing and never miss a note."

!Duncan Idaho
Another Atreides retainer, he serves as the House's swordmaster, responsible for managing the household's defenses. He [[spoiler:dies in the first book, only to be reincarnated over and over again in later books.]]

* AscendedExtra: He appears more than any of the main characters of the entire series.
* [[spoiler:BackFromTheDead]]: Repeatedly in the later installments.
* ButtMonkey: [[spoiler:He is reincarnated as a ghola. Again. And again. And again. And again. And killed (rather than dying of old age) only a slightly smaller number of times]].
* TheCasanova
* ChickMagnet: Hinted at in the first book, outright stated in ''Heretics'' when he counter-seduces the Honored Matre Murbella.
* [[spoiler:CloningBlues]]
* [[spoiler:HeroicSacrifice]]: Why he dies in ''Dune''.
** Does it again in Children of Dune.
-->''"Two deaths for the Atreides. The second for no better reason than the first."''
* MasterSwordsman: Though by his own admission, not quite as good as Gurney ("Gurney could best me six times out of ten.").
* OldRetainer: Via the [[spoiler:gholas.]]
* [[spoiler:TheyKilledKennyAgain]]

[[/folder]]

[[folder:Fremen]]

!Liet-Kynes
A half-fremen Planetologist continuing his hope of bringing water to Arrakis. Temporarily appointed Judge of the Change.

* BadassBookworm
* BadassFamily: Tales of his father are legendary in their own right.
* DeathByIrony: A planetologist killed by his own planet; even more poetically, by a spice bed! Kynes realizes the folly of his 'science' as he dies.
* HeroicVow: Bringing back water to Arrakis and terraforming it into a lush world.
* HisNameIs: Felled by sunstroke and about to be sucked underground, Kynes has a breakthrough over how to fertilize Arrakis.
* HopeSpot: There's hope that some Fremen will spot the carrion birds overhead and come investigate. Kynes is killed by a whirlpool before this can happen.
* IHaveManyNames: "I am accepted in both sietch and village."
* MauveShirt: Of the captives stranded in desert by Sardaukar, only Kynes bites it.
* NatureHero
* NobleSavage
* ScienceHero
* SeekerArchetype

!Chani

* ActionGirl
* BadassFamily: She is Liet's daughter, after all.
* LoveInterest: To Paul.
** BattleCouple
** HotConsort
* [[NatureHero Nature Heroine]]
* [[ProudWarriorRaceGuy Proud Warrior Race Gal]]: She's a fierce warrior, like all Fremen.

!Stilgar
Fremen Naib (chief) who mentored Paul in the ways of the Fremen. After Paul's ascension to Emperor, he becomes one of Paul's generals and the guardian of his children.

* AsskickingEqualsAuthority[=/=]KlingonPromotion : The method by which Fremen choose their chiefs, with Stilgar being no exception. Paul, however, spares him, reasoning that he does not want to waste a useful talent.
* [[BedouinRescueService Fremen Rescue Service]]
* DefeatMeansFriendship: He's dismissive of Jessica when he first meets her, but takes her seriously after she subdues him in hand-to-hand combat. The two become friends and allies afterwards.
* DemotedToDragon: After Paul refuses to go through with the KlingonPromotion rite.
* BestFriendsInLaw: With Pardot Kynes, who married his sister - Frieth.
* HadToBeSharp
* TheMentor: To Paul, and later to Leto.
* NobleSavage: A subversion, as with the Fremen in general. He's certainly among the most noble Fremen, but even he is not without shades of gray.
* ProudWarriorRaceGuy: He's a leader and distinguished warrior among the Fremen.
* ReasonableAuthorityFigure: He's both a friend and father figure to Paul throughout the series.
* WastelandElder

!Jamis

A Fremen man who challenges Paul to a duel.

* AssholeVictim: He's an angry, domineering man who wants to kill Paul for being an outsider. When Paul kills him in ritual combat, his widow Harah is indifferent and his sons are delighted to have Paul as their new father, suggesting that he wasn't a kind father or husband.
* DueToTheDead: Even though all evidence suggests that Jamis is a rotten human being, his fellow Fremen respectfully mourn his death.
* HairTriggerTemper: He's an angry man who's enraged at the idea of Paul and Jessica joining his sietch. When Stilgar tries to reason with him, it just makes him angrier.
* KarmicDeath: Jamis has a history of killing men he didn't like. He challenges Paul to a duel, but dies at Paul's hands.
** Years before, Jamis challenges a man to a duel specifically so that he could kill him and take his wife. Jamis himself is killed in a duel, and his wife and sons inherited by another man.
* YouKillItYouBoughtIt: In duels between two Fremen men, the winner inherits the loser's family. Jamis exploits this tradition by killing Harah's first husband so that [[MaritalRapeLicense he can have Harah for himself]]. Paul later inherits responsibility for Harah and her sons when he kills Jamis.

[[/folder]]

[[folder:Harkonnens and Supporters]]

The Harkonnens are House Atreides's ArchEnemy, and are evil to a fault, with possibly one exception. But then again, [[NotSoDifferent things are not so simple as that.]]

!Baron Vladimir Harkonnen

* AllYourBaseAreBelongToUs: Leto learns the hard way that the governor's mansion was just on loan.
* BadBoss: His subordinates survive [[YouHaveOutlivedYourUsefulness just so long as they're useful to him]] and not a second longer. As well, he's a big fan of YouHaveFailedMe and HeKnowsTooMuch. Even his own family isn't exempt, as Rabban might have discovered if thing had gone more to the Baron's intentions. Just about the only one who is relatively safe from him is his nephew Feyd-Rautha, who the Baron is grooming to succeed him and who he doesn't want to throw away unless absolutely necessary.
* BigScrewedUpFamily: His raising Count Rabban and Feyd-Rautha Harkonnen as his own led to them being severely dysfunctional.
* BestServedCold: Seeks to avenge House Harkonnen's uprooting from Arrakis. The real source of his animosity stems from a Hatfield-[=McCoy=] [[FeudingFamilies feud]] with House Atreides.
* BigBadDuumvirate: With Emperor Shaddam Corrino IV, who supplies him with an entire legion of elite troops as well as warships.
** [[spoiler: Bigger Bad: During Children of Dune he's using and influencing Alia even though he's dead, thanks to her GeneticMemory.]]
* CainAndAbel: Despised his brother Abulurd's "bleeding heart" nature. He also had him murdered and then took custody of his nephews.
* TheChessmaster
* DepravedHomosexual: He has slave boys delivered to his quarters, and the ''Dune Encyclopedia'', though not canonical, hints that his attractions may extend to Feyd-Rautha. There are hints of it in the David Lynch film as well. He certainly had designs on Paul, but gave them up when he realized how lethally dangerous the boy was.
* EvenEvilHasStandards: Would have preferred to torture Leto in private, one nobleman to another. For one, it sets a bad precedent for the next ruler of Arrakis. Also, if word got back to the other Houses that the Imperium is involved, everyone would be terrified the Emperor's coming for ''them'' next. However, the Baron quickly loses his patience when Leto doesn't bend.
* EvilGenius
* EvilIsPetty: The Baron prides himself on not "wasting" good men -- but he'll murder you over a trifling offense.
* EvilUncle: Rabban and Feyd don't take after their dad, obviously.
* FatBastard: Is so overweight he needs antigravity support to move.
* '''FauxAffablyEvil''': He seems like a jolly man, with his mannerisms and constant use of endearments... but he's actually a diabolic power-hungry schemer.
* FoeYay:[[invoked]] Arranging for a Paul lookalike to be drugged up and sent to his bedchamber.
* GenghisGambit: Intends to use his nephew Rabban as the fall-guy in one of these, but it doesn't work out, due to the Fremen uniting behind Paul Atreides instead. In the film version, it only succeeds in drawing the attention of the Emperor who demands to know why the Baron has made such a hash of things on Arrakis, threatening the flow of spice to the entire known universe.
* KarmicDeath: Poisoned by the daughter of his enemy.
* KineticWeaponsAreJustBetter
* LargeHam: In every sense of the word. In the film, this includes flying around the room laughing maniacally after outlining his scheme to his nephews.
* LukeYouAreMyFather: One of his cast-off concubines (there are hints it's Reverend Mother Mohiam; this is hinted at in the David Lynch film and confirmed in the prequels) gave birth to Jessica, making him Paul's grandfather. Which he didn't know until right before his death at Alia's hands.
* TheManBehindTheMan: Rabban was his puppet ruler, with Feyd-Rautha planned to succeed him.
* ManipulativeBastard
* NoMisterBondIExpectYouToDine: Propping up Leto's paralyzed body in a dining room chair, then proceeding to negotiate with him over lunch.
* ObfuscatingStupidity / StupidEvil: When Feyd-Rautha's assassination attempt fails, Vladimir orders the deaths of the slavemaster and two nearby guards for seemingly pointless reasons; the slavemaster just lost to Feyd at Chess, and the guards were not carrying a corpse with enough dignity. What he did not say out loud was that he was killing off Feyd's co-conspirators under the guise of EvilIsPetty.
* SissyVillain: Somewhat. Not outwardly visible, though.
* TheSocialDarwinist: His soliloquy about rabbits, and how fear and power are the tools of statecraft, mark him as this.
* TheSociopath: He's devoid of any moral compass and values no life. His cruelty and depravity demonstrate his lack of moral concern for others.
* VillainousIncest: He actually ''ogles'' his nephew, Feyd. To say nothing of his attraction to Paul.
* WeHaveReserves: His reaction to Leto's final attack is to close the door on his own men, leaving them to die from poison gas. (In the miniseries, he simply flies away from the range of the gas.) His immediate reaction was joy that they had died and ''he'' survived. He also casually kills off Leto's troops rather than recruit them, but then again, they were hardly likely to serve him.

!Piter de Vries

* AmbiguouslyGay: Very effete and Baron Harkonnen repeatedly insinuates that he's not really attracted to Jessica and only desires her as a status symbol.
* [[spoiler:AnyoneCanDie: Is taken out by Leto's attempted TakingYouWithMe, whose real target was the Baron.]]
* AwesomeByAnalysis
* ContestWinnerCameo / TakeThatCritics: Possibly named for the American novelist Peter de Vries.
* TheEvilGenius
* IHaveYouNowMyPretty: He intended to do this, but the Baron convinced him that raping Jessica was a ''really'' stupid idea (more exactly, he was offered Jessica and exile-- in case she turned or killed him-- or Arrakis, and his love of power won).
* PsychoForHire
* SissyVillain
* SpellMyNameWithAnS: His name is given as 'Piter de Vrie''d'' in some editions of the first book.
* TortureTechnician
* YouHaveOutlivedYourUsefulness: The Baron continually makes note to kill him, but Piter's [[SubvertedTrope prematurely bumped off]].

!Feyd-Rautha Harkonnen
* BadassNormal: Holds his own against the Kwisatz Haderach. Questionable how normal he is though. He's had the same intense level of combat training that Paul has, with added lessons in how to fight dirty in a nominally "clean" contest.
* BastardUnderstudy: The Baron is grooming him to be the next ruler of Arrakis, and perhaps even Emperor.
* TheDragon: To his uncle
* EvilCounterpart:
** Count Fenring laments that Feyd [[ForWantOfANail was raised the way he was]]; if he hadn't, Feyd could have turned out like Paul. He is of course, [[spoiler:Paul's first cousin]]
** Feyd is also the remaining male from the Bene Gesserit genetic selection line (discounting the renegade Paul), making him their last hope (except for Feyd's bastard daughter). Furthermore, he was most likely supposed to be one of the parents of the Kwisatz Haderach, with Jessica and Leto's child being the other.
* LetsDance: The duel opens with Feyd complimenting Paul's "dancing."
* NotCheatingUnlessYouGetCaught: "On his seventeenth birthday, Feyd-Rautha Harkonnen killed his one hundredth slave-gladiator." That's because each of those slaves was drugged or programmed to respond to {{Safe Word}}s. And of course, his weapons are all poisoned. This time he faces one of Leto's elite troopers, and he very nearly winds up dead despite the deck being stacked in his favour.
* TheSociopath: Much like his uncle. Feyd has no moral compass and no qualms about senseless killing.
* SmartPeoplePlayChess: The Baron gingerly broaches the topic of the latest attempt on his life (by Feyd) by pointing out the Pyramid Chess set in his room.
* TheStarscream: The Baron is aware of Feyd's continual attempts to kill him, and forces Feyd to kill his sex slaves one-by-one and by hand to curb his ambition (after filling his head with promises of the imperial throne).
* VillainWithGoodPublicity: The Baron notes "He could walk unarmed and unshielded through the poorest quarters." Its another parallel with Paul.
* YouFightLikeACow
* YouKilledMyFather: Well, his uncle, really, but he attempts to avenge the Baron. However, as he was not above [[TheStarscream trying to kill the uncle himself]], it's likely that he's just angry that the person got the chance to kill Harkonnen whereas he didn't.

!Count Glossu Rabban
* AscendedExtra: He has only one brief appearance in the original book, he is a considerably more significant character in the film, miniseries, and prequels.
* TheBrute: The Baron describes him as a "muscle-minded tank-brain". Played straight in the movie, but subverted in the first book, in which Rabban is [[SmarterThanYouLook insightful about the potential Fremen threat]].
* TheCassandra: He warns his uncle that the Fremen deserve attention and encourages him to undertake a Fremen census on Arrakis, but the Baron refuses to listen.
* GenghisGambit: His uncle sets him up as [[UnwittingPawn the fall-guy]] in one of these, ordering him to squeeze Arrakis dry (well, [[SingleBiomePlanet metaphorically speaking]]) and crush all resistance, while intending to dispatch his other nephew Feyd to kill and replace him as a far more benevolent ruler.
* KnowWhenToFoldEm: In the miniseries, when he was attacking the Harkonnen city (presumably on the Baron's orders), he is encountered by the citizens who were present. When he realizes that he's not only outnumbered, but he's going to suffer immediate death as a result and not capture, his reaction is to drop his weapon and scream to the heavens, not doing even one thing to delay his death. His death is not described in the books.
* NamesToRunAwayFromReallyFast: Known by a plethora of titles on Arrakis, including "Mudir Nahya" (Demon Ruler), King Cobra, and Beast Rabban.
* OffWithHisHead: His ultimate fate in the miniseries, and in the David Lynch film (albeit at a different set of hands).
* SmarterThanYouLook:
** The Baron is convinced that he's a dolt. However, Rabban was regent of Arrakis for years and learned a thing or two -- namely, ''don't mess with the Fremen''.
** In the first novel, he suggested to the Baron that they perform a count of the Fremen on Arrakis, which the Baron immediately rejects. If the Baron had listened to his nephew, he might have been better prepared to fight the Fremen later.
** And Rabban does get in a very astute question to the Baron regarding the Baron's subversion of Yueh, which causes the Baron to at least wonder how smart Rabban really is.
* TheUnfavorite[=/=]OffingTheOffspring: The Baron planned to have Rabban rule Arrakis again then and have Feyd kill him to make him loved and praised.

[[folder:House Corrino and Supporters]]

!Emperor Shaddam Corrino IV
* AnOfferYouCantRefuse: Here, have this planet-sized DeathTrap with no way out except through the Guild which takes my bribes.
* TheEmperor
* TheEvilPrince
* TheExile: After abdicating the throne to Paul, Shaddam is banished to the Sardaukar prison planet.
* FriendlyEnemy: In secret, Shaddam admires his cousin Leto, and had once mentioned to Irulan that he had wished the political climate that necessitated wiping out the Atreides did not exist. As it stands, the Emperor orders Leto's death simply for having a more powerful army than him.
* LaserGuidedKarma: The Emperor boots Leto out of Caladan, only for his heir to return and unseat him from the throne.
* NoHonorAmongThieves: His paranoia won't allow him to leave the Baron alive [[HeKnowsTooMuch with what he knows]].
* PuppetKing: Although Shaddam has some power he's ultimately at the mercy of The Guild. Meanwhile the Bene Gesserit has ensured all of his legitimate children are daughters and the Emeperor can't do anything about it.
* ProperlyParanoid: He suspects the Harkonnens of moving against him... which is actually the case. In fact, the Baron anticipated Corrino's wrath and planned to unify the Houses against him.
* TheSocialDarwinist: The Emperor is known for his open contempt of "weakness". When the Sardaukar find Leto's body, the Baron flies into a panic-- not because he killed Leto, but because he botched the job. Word of the poison gas will get back to the Emperor, who will make life difficult for him.

!Count Hasimir Fenring
A counselor and friend of Emperor Shaddam; also an assassin. Was one of the Bene Gesserit's recent failures.

* {{Badass}}: Implied. After the Emperor sees Paul fight he concludes that Fenring would be able to take him easily even if he wasn't exhausted.
* TheDragon: To Shaddam IV.
* EunuchsAreEvil: Sort of. He is one of the most sympathetic of the villains and serves out of loyalty to the Emperor.
* FlawedPrototype: At the end of Dune, he is revealed to be [[spoiler:a failed Kwisatz Haderach.]]
* HappilyMarried: ''Very'' much like Jessica and Leto. With one small exception...
* ImmuneToFate: Although he [[spoiler: falls short of being a true Kwisatz Haderach]], he's close enough that Paul can't read him.
* MyMasterRightOrWrong
* NotSoDifferent: Even Paul admits this at the end.
* ObfuscatingStupidity: Seems little more than a harmless fop, but is actually much smarter and deadlier than he looks.
* PunchClockVillain
* SexlessMarriage: He and Margot are fairly happy together, but he is physically incapable of sex.
* SpellMyNameWithAnS: ''Children of Dune'' spells his first name as "Hassimar".
* VerbalTic: "Hmmmm." It actually serves as a form of cipher which only him and his wife can understand.

!Princess Irulan

One of the emperor's daughters and known to have had some Bene Gesserit training, though due to being of royal blood she never reached whatever potential she may have had due to some sense of entitlement and haughtiness she could never quite remove sufficiently. She's known to have 'literary aspirations' and provides many of the chapter quotes in the form of biographies written after the fact.

* [[spoiler:AndNowYouMustMarryMe]]
* TheChewtoy: Her life after the end of the first book is essentially a constant chain of being abused, manipulated, insulted and discarded. Only one person ever shows any explicit concern for her as a person, and then only when she considers killing Irulan if she gets in her way.
* DaddysGirl: She seems to have had some affection for her father TheEmperor.
* EncyclopediaExposita: Quotations from her commentaries are used as the headings for each chapter from ''Dune'' onwards.
* FallenPrincess: She's beautiful, dutiful, intelligent and talented. She was being groomed to be the wife of the Bene Gesserit Totality, but when she finally achieves that [[spoiler:Paul relegates her to a wife in name only role and almost completely ignores her whenever possible.]] Further, any power she has is token and only afforded to her because it would be politically impossible to strip her of ''all'' power.
* HazyFeelTurn: At the end of the second book [[spoiler:she switches into the Atreides camp after Paul walks into the desert to die and she only then realizes she actually loved him]].
* ParentalSubstitute: She never has children of her own with her husband [[spoiler:but after he "dies" she leaves the sisterhood in order to raise his children as though they were her own.]]
* ProperLady
* SexlessMarriage: At the end of the Dune [[spoiler:Paul marries her to gain the throne, but tells Chani she will not have a hint of warmth from him. Chani]] remains his true wife in all but name [[spoiler:and Jessica assures her that that is exactly how history books will record her.]]
* SpoiledBrat: The fundamental reason that she remained a mere Bene Gesserit sister rather than a full Reverend Mother or even just a particularly talented pawn was that thanks to her upbringing as a princess she never learned to make full use of the training provided to her.
* StockholmSyndrome: She would be perfectly loyal to Paul is he would just grant her the right to bear his heir. [[spoiler:After the second book ends she realizes she had fallen in love with him and betrays the Bene Gesserit to become the mother of the twins.]]


!Wensicia Corrino

!Farad'n Corrino

!The Sardaukar

The private army of the Padishah Emperor.

* AlwaysSomeoneBetter: The Sardaukar are so good because [[spoiler:they are trained on the DeathWorld of Salusa Secundus]]. Leto (and Paul) correctly figure out that Arrakis is an even worse DeathWorld and so its inhabitants, the Fremen, will be able to beat the Sardaukar.
* AsskickingEqualsAuthority
* BackToBackBadasses: In close combat and when outnumbered, Sardaukar are trained to fight in formations of three so they never show their backs to the enemy.
* BadassArmy
* CommonRanks: Their ranks are a combination of traditional Western ones and Arabic titles to go with Dune's cultural mix theme, such as "Colonel-Bashar".
* CrazyPrepared: To the point of equipping themselves with fake toes (with stabbing implements!) and garrotes in their hair in the form of shigawire.
* CulturedWarrior: Tyekanik and the higher-ranked Sardaukar end up adapting some aspects of the Fremen faith, finding common ground there with their experiences.
* DeathWorld: All the Sardies get a TrainingFromHell upbringing [[spoiler:on Salusa Secundus, the devastated former seat of House Corrino (a wasteland planet similarly harsh and inhospitable as Arrakis)]].
* EvilArmy: At least from the Atreides and Fremen point of view. [[JustifiedTrope But make no mistake]] - they can be cruel and thorough.
* FalseFlagOperation: See PaperThinDisguise below.
* [[MyMasterRightOrWrong Our Master Right Or Wrong]]
* PaperThinDisguise: Shaddam Corrino IV sends two full legions of Sardaukar in the guise of Harkonnen soldiers to bolster their assault on the Atreides after Yueh's bertayal. The Atreides pick up on this almost immediately, recognizing the incredibly distinct and vicious fighting style of the Sardaukar. The Sardaukar even attempt disguising themselves as Atreides soldiers during the assault.
* [[spoiler:PenalColony]]: Salusa Secundus, where they are trained.
* PraetorianGuard: To the Padishah Emperor.
* TheSpartanWay
* TheStoic: Captain Otto Aramsham, who refuses to submit under capture by Paul and the Fremen until he uses the Voice.
* TrainingFromHell: How they become as skilled as they are.
* VillainousValour
* WeaponizedExhaust: The Sardaukar used this to barely eke out a victory/capture of some Fremen.
* WeHaveBecomeComplacent: For many years, the Sardukar were able to coast on their ''reputation'' as being unbeatable in combat, and thus their skills atrophied, though they were still a force to be reckoned with by the time of the first book.
* WorthyOpponent: To the Fremen, at least in comparison to Harkonnen soldiers.

* TheConsigliere: To the Emperor.
* EvilMatriarch / EvilOldFolks: She's the highest-ranked Bene Gesserit, an evil schemer, and an all-around {{jerkass}}.
* {{Jerkass}}: She's scathing to Jessica, Paul, and others.
* KilledOffscreen: Stilgar kills her offscreen near the end of ''Dune Messiah''.
* LivingLieDetector: As the Emperor's Truthsayer.
* ManipulativeBitch

!Margot Fenring

* HappilyMarried: Despite everything, she and the Count do love one another.
* SexlessMarriage: Mostly because the Count is incapable of sexual intercourse.
