->"''I'm proud to say I've written another insane admiral. They must put something in the water at Federation Headquarters.''"
-->-- '''Ronald D. Moore'''

In fictional military settings, the brass tend to be a bit unstable. Frequently they become so obsessed with their own pet projects that they endanger [[TheFederation national security]]. Other times their brazenness and/or [[GeneralRipper paranoia]] almost leads to wars breaking out between rival superpowers. They may be a ConspiracyTheorist with authority investigating the heroes, an ObstructiveBureaucrat making hell for the heroes, or they may be covering up for their own wrongdoings. These are the ones most likely to send the heroes on a dubious mission. They could be a GeneralRipper obsessed with the enemy, or they could be cowards who fear public exposure of their own wrongdoings.

All this insanity might make their organizations look incompetent, but presumably the Insane Admirals are just the ones we see... 95% of the brass in any given organization are probably decent folk, but spend their time rubber-stamping military contracts and attending state functions, and never do anything 45-minute drama-worthy. Please note this applies only to officers who are at command level, no one below the rank of Naval Captain/Army Colonel/Airforce Group Captain applies here, see TheNeidermeyer and SociopathicSoldier for those.

The unfortunate combination of BadBoss and WeAreStrugglingTogether. GeneralRipper is a major SubTrope of this. And see also KickedUpstairs, which is frequently how they end up getting to be Insane ''Admirals'' instead of insane forty year-old ensigns.

[[folder:Anime and Manga]]
* [[GeneralRipper Admi]][[WeHaveReserves ral]] [[LackOfEmpathy Akainu]] in ''OnePiece''. Among other things, he destroys a boatload of civilians [[DisproportionateRetribution because one scholar might have slipped on board]], he's shown interest in buying and using [[WeaponOfMassDestruction the incredibly deadly weapons created by Caesar Clown]] in spite of the fact that they render entire islands uninhabitable, and [[WeHaveReserves forcing the soldiers at Marineford to keep fighting at the cost of their lives, even though their main objective had already been completed.]]
* The two admirals from ''IrresponsibleCaptainTylor''. Their arguments always end with them trying to kill each other. ([[VitriolicBestBuds But they're really friends]])
* Fittingly, since the Franchise/{{Gundam}} franchise is largely considered to be ''Franchise/StarTrek'''s Japanese counterpart, it contains an equally disproportionate number of high ranking nutcases:
** Gihren Zabi of the original ''Anime/MobileSuitGundam''. He's Zeon's commander-in-chief, a brilliant [[RousingSpeech public speaker]] and the [[DragonInChief real power]] behind his [[PuppetKing aging father]], [[NonActionBigBad Sovereign Degwin]]. He's also a [[TakeOverTheWorld megalomaniacal]] [[TheSociopath psychopath]] and SocialDarwinist with a [[ANaziByAnyOtherName fascist]] [[MasterRace philosophy]] and a limited grasp of what it means to be a human being. This causes him to commit a number of tactical errors later in the series, and he adopts a very "Hitler in the bunker" type attitude by the end.
*** Char Aznable doesn't start out as one of these. In fact, it would be fair to say that in ''MSG'' he's about as rational as a man plotting the deaths of all his superiors can be. By the time ''CharsCounterattack'' rolls around, however, this is no longer the case. Totally out of touch with the rest of humanity, and drunk on his own political ideology, he attempts to [[ColonyDrop drop a meteor on the Earth]] claiming that this will somehow bring about [[UtopiaJustifiesTheMeans world peace]]. Privately, he admits that he's "extremely wicked" and is endangering the world solely so that he can gain revenge on [[TheHero Amuro]], and appease the memory of his late LoveInterest, Lalah Sune.
*** Zeon Rear-Admiral Ginias Sahalin of ''Anime/MobileSuitGundamThe08thMSTeam'' is no picture of mental health. The head of the Apsalus project, his MommyIssues, combined with his obsessive need to control his sister and claim all the credit for the project cause his mind to degenrate over the course of the series. By the end he's an AxeCrazy maniac who is ready to murder everyone around him, including his sister and all of his researchers, if it means that he gains sole control of the Apsalus III. This, combined with his IllBoy status, has caused some fans to speculate that he has Wilson's Disease, a degenerative neurological condition that often causes schizophrenia-like symptoms.
*** There is something in the water at the Zeon command centre. Gihren loyalist [[NamesToRunAwayFromReallyFast Colonel Killing]] from ''Anime/MobileSuitGundam0080WarInThePocket'' murders his commanding officer and usurps his position, orders a nuclear strike on a colony, and cares nothing for his own troops, deliberately sabotaging a mission in order to gain permission for his nuclear attack.
** [[TakeOverTheWorld Jamitov Hymem]] and [[ShellShockedVeteran Bask Om]] from ''[[Anime/MobileSuitZetaGundam Zeta Gundam]]'' are respectively the [[BigBad commander]] and [[TheDragon field leader]] of the [[StateSec Titans]], the Earth Federation security force that occupies the colonies. Jamitov is an admiral with [[SmugSnake delusions of grandeur]] who seeks to gain control of the entire Earth Sphere for himself and plots against civillian leaders and the rest of the brass. Bask is a ColonelKilgore and GeneralRipper with a fanatical loathing of all colonials, which stems from [[BeingTorturedMakesYouEvil his time being tortured in a POW camp during the One Year War]]. His hatred and brutality are so extreme that [[AxeCrazy madness]] is really the only explanation that works.
** Patrick Zala of ''Anime/MobileSuitGundamSEED'' is an utterly paranoid and psychotic GeneralRipper, with both WhatTheHellDad and [[FinalSolution genocidal]] tendencies, who wants to exterminate every [[PunyEarthlings Natural]] in existence in {{Revenge}} for an attack on a ZAFT colony. His right-hand man, Commander [[WoobieDestroyerOfWorlds Rau]] [[BrokenAce Le]] [[NietzscheWannabe Creuset]] is [[spoiler:[[MisanthropeSupreme even worse]], being an OmnicidalManiac who's out to get everyone on ''both'' sides killed]]. On the opposing side, we have Captain William Sutherland of the Earth Forces [[ObstructiveBureaucrat General Staff]], who masterminds the use of the [[WeaponsOfMassDestruction Cyclops]] system against his own men, authorises the use of [[NukeEm nuclear weapons]] against ZAFT, serves as [[CorruptCorporateExecutive Muruta Azrael's]] [[TheDragon Dragon]], and is a card-carrying member of [[FantasticRacism Blue Cosmos]], a hate group that seeks the deaths of every last [[GattacaBabies Coordinator]].
* All the members of the senior staff fall under this in ''Manga/FullMetalAlchemist''. {{Justified|Trope}} by the fact that Father needs willing pawns for his plotting, and this collection of megalomaniacal asshats is the best he can come up with.
* Some of it is cultural differences but even by [[LightNovel/CrestOfTheStars Abh]] standards some of their admirals are a little off their rockers. Specifically Admiral Spoor who rejoices in the [[TheRedBaron nickname]] 'The Lady of Chaos' and Admiral Bibauth who is desperately trying to distance himself from the family nickname 'The Beautiful Madness' and in the process making himself look even worse. They are fortunately both fairly competent and aided by competent subordinates but definitely considered rather eccentric.
[[/folder]]

[[folder: [=FanWorks=]]]
* [[FanFic/GameOfTouhou Ser Mononobe Futo]] uses wildfire to strike Murasa's fleet (who herself launches anchors from trebuchets). Due to the highly explosive nature of [[MeaningfulName wildfire]], she [[PyrrhicVictory destroys the opposing fleet and most of her own fleet]], [[spoiler:and she's rescued by [[ThisIsGonnaSuck Gengetsu]].]]
[[/folder]]

[[folder:Film]]
* Colonel Quaritch in Film/{{Avatar}} shoots at anyone who non-lethally leaves his faction, and he goes on a RoaringRampageOfRevenge against the protagonist after his plans have been completely foiled.
* Colonel Kurtz in ''Film/ApocalypseNow''
* The General in ''Film/{{Z}}''
* From ''DrStrangelove'', General Jack D. Ripper.
** General Buck Turgidson, while much more grounded than Ripper, definitely has his moments as well.
* General Leland Zevo in ''{{Toys}}''
* PlayedForLaughs in ''HotShots'' with Admiral Benson, an amicable kook who tries to order the whole ''fleet'' to turn around and go back when his Admiral's hat blows off while on deck.
* Subverted in ''MarsAttacks'': General Decker ''seems'' like a raging whacko, but he turns out to be right about the Martians from start to finish. (He's still wrong about how to beat them, though.)
* ''Film/StarTrekIntoDarkness'': [[spoiler:In grand Trek tradition, Admiral Marcus is really a BloodKnight seeking to start a war between the Federation and the Klingon Empire. He has no compunction about murdering loyal Starfleet officers in cold blood]].
* Played for laughs with retired Admiral Boom in ''MaryPoppins''.
[[/folder]]

[[folder:Literature]]
* Anyone with the rank of Colonel or above in ''Literature/CatchTwentyTwo''
* [[http://en.wikipedia.org/wiki/Captain_Queeg Captain Queeg]] in ''TheCaineMutiny'', both the original novel and the FilmOfTheBook. His bizarre behavior eventually causes a subordinate to relieve him of command.
* Captain Sawyer from the ''HoratioHornblower'' books.
* General Patton in HarryTurtledove's {{Timeline-191}} series
* In the StarWarsExpandedUniverse isn't short of crazy senior military officers. The vast majority are in the employ of the various Sith run empires throughout history, but that isn't surprising given the Sith not only bring their own level of crazy to anything they get involved in, but encourage it in others.
** Admiral Natasi Daala in the JediAcademyTrilogy series. She returns in the FateOfTheJedi series as a crazy head of state.
** Captain Joak Drysso in the XWingSeries novel ''The Bacta War''
** Most of the various Warlords that broke away from the Empire following the Emperor's death in ROTJ tended to be a bit extra crazy as well. A bunch of them get out crazied by Daala who gets them all to a peace summit and then gases them to death when they can't come together to present a unified front. [[spoiler:ironically, this ends up ensuring the [[VestigialEmpire Imperial Remnant]]'s survival, as by the end of that particular crisis its leadership ends up in the hands of Admiral Pellaeon, the Imperial OnlySaneMan ''par excellence''.]]
* Admiral Bell in ''Literature/VarneyTheVampire'', while protective of his family and a generally decent guy, acts like a complete lunatic in most situations.
* The Literature/VorkosiganSaga gives us Vice-Admiral Ges Vorrutyer, who combines dangerous military adventurism with a brutally manipulative attitude to his companions' lives, and in his spare time is a serial rapist.
* ''Literature/TheDrownedCities'': Colonel Glenn Stern of the United Patriotic Front is a KnightTemplar madman who believes he is saving America (something he barely understands the concept of) by chopping off the hands and feet of those he takes prisoner, and turning children into [[ChildSoldiers soldier boys]]. His archrival, General Sachs of the Army of God is implied to be just as crazy, as are the leaders of Taylor's Wolves, Tulane Company, the Freedom Militia, and all the other groups in the story.
* This is the default mindset for [[AlienInvasion Yeerk]] Vissers in ''Literature/{{Animorphs}}'', most of whom are shown to be motivated more by their personal agendas rather than military objectives. The standout is Visser Three [[spoiler:(later Visser One)]], the BigBad of the entire series. A dim-witted egomaniac with an unquenchable thirst for violence and a questionable grip on reality, Visser Three finds every excuse he can to butcher his own subordinates, spends the rest of his time playing politics with his superiors, and reacts to defeat like an angry child. His fanatical subordinate, Visser Two, is even ''[[UpToEleven more]]'' crazed, if that's possible to imagine. He also gets bonus points for taking an actual admiral as his host.
** Interestingly, Visser Three actually shows far more effectiveness, restraint, and... well, ''sanity'', in the prequel ''Chronicles'' books. He gets a narrating role in ''The Hork-Bajir Chronicles'' in which he's downright the OnlySaneMan among the Yeerks invading the Hork-Bajir homeworld.
** Subverted by [[spoiler:the original]] Visser One, who seems to have taken Esplin's role as the OnlySaneMan in the Yeerk Empire in the present day.
* In ''[[Literature/StarTrekTheLostEra Star Trek: Serpents among the Ruins]]'', Admiral Aventeer Vokar is the Romulan ArchEnemy of Captain John Harriman of the USS ''Enterprise''-B. While Vokar doesn't fit this trope, the main plot of the novel involves portraying him as one while setting up the now-infamous Tomed Incident, in which Vokar's flagship ''Tomed'' performed a suicide run at a Federation sector and deliberately destabilized its quantum singularity while at high warp. The resulting EarthShatteringKaboom destroyed a number of outposts and a Federation starship, costing the lives of tens of thousands of Federation citizens. However, this was actually a Starfleet Intelligence operation, involving Harriman, to infiltrate the ''Tomed'' and set up the suicide run, while the outposts and the Federation starship were actually empty. The only casualties of the operation were Vokar himself and his crew.
[[/folder]]

[[folder:Live-Action TV]]
* ''Series/AlloAllo'': ThoseWackyNazis, with any officer above the rank of Colonel really (resident cast members are Colonel Von Strom and General Von Clinkerhoven). Again, the insanity is PlayedForLaughs.
* ''Series/BabylonFive'': Colonel Ari Ben-Zayn.
* ''Series/BattlestarGalacticaReimagined'' (2000's): Admiral Cain, of course.
* ''Series/{{Blackadder}} Goes Forth'': General Sir Anthony Cecil Hogmanay "Insanity" Melchett, whose determination to move his drinks cabinet six inches closer to Berlin inspired many a "Big Push".
* ''Series/DoctorWho'': In the Tom Baker episode ''The Ribos Operation'' (part 1 of the ''Key to Time'' adventure), the Graf Vynda-K is the perfect example.
* ''Fawlty Towers'': Major Gowen (although a retired officer), doesn't know what day of the week it is. Then again, how much of this is simply due to the Major being frequently inebriated, we're not entirely sure.
* ''Series/HoratioHornblower'': Captain Sawyer from this MiniSeries [[FilmOfTheBook adaptation]]. His case is PlayedForDrama. He starts as viciously critical and unjust, continues to be extremely paranoid and ends up genuinely mad. His lieutenants are in an unenviable position, especially when the ship's surgeon is Captain's friend, [[TheAlcoholic an alcoholic]] and unwilling to pronounce him unfit for command. Whatever steps they consider to take would be ultimately a mutiny.
* ''Series/{{MASH}}'': Major General Bartford Hamilton Steele from the episode "The General Flipped at Dawn". He is promoted at the end to boot, after dancing a jig to 'The Missisippi Mud' out of a court-martial. On rare occasions, his lookalike Potter showed signs of a crazy edge--but considering the camp he ran, he can be forgiven.
** Potter actually subverts it. For most of his first episode, [[TyrantTakesTheHelm he seems to be overly uptight]], but then proves himself to simply be a ReasonableAuthorityFigure who needed to establish himself in a position of authority before [[FatherToHisMen getting close to his troops]]. His gruff nature and occasional apparently nutty idea comes partly from working in a unit where virtually everyone was a BunnyEarsLawyer, and partly from having SeenItAll.
* ''Series/MissionImpossible'': In "Submarine", the IMF have to stop a U.S. Navy admiral who sank one of his one subs as a demonstration of a weapons system he was planning to sell on the black market. He did this because he felt betrayed by the government conducting weapon limitation talks with the Russians, which stopped his computer virus attack system ever going into production.
* ''Series/{{Revolution}}'': Bass Monroe in turns this UpToEleven as an unhinged ''military dictator'' of the Monroe Republic (formerly the northeastern US and parts of Canada). As the show goes on, it becomes a DeconstructedTrope, with loyal officers [[spoiler: Mile Matheson (revealed to have been one in [[Recap/RevolutionS1E3NoQuarter episode 3]]) and Tom Neville (occurred in [[Recap/RevolutionS1E13TheSongRemainsTheSame episode 13]])]] betraying him, because he would have had them killed. His paranoia and insanity causes a lot of competent officers to be killed off, including [[spoiler: Colonel John Faber ([[Recap/RevolutionS1E8TiesThatBind episode 8]]), a militia captain who worked under Neville ([[Recap/RevolutionS1E14TheNightTheLightsWentOutInGeorgia episode 14]]), and Jeremy Baker]], who calls him out on his behaviour before his death in [[Recap/RevolutionS1E17TheLongestDay episode 17]]. In fact, by the [[Recap/RevolutionS1E20TheDarkTower first season finale]], [[spoiler: Tom Neville takes over the Monroe Republic and Bass Monroe is left to run off on his own]].
* ''{{Sharpe}}'': This trope tends to turn up in this series, probably the most extreme (although far from unique) example from that series is Sir Henry Simmerson.
* ''Franchise/StarTrek'':
** ''Series/StarTrekTheOriginalSeries'':
*** "The Doomsday Machine" - Commodore Matt Decker is [[DespairEventHorizon driven mad]] after watching the titular machine kill his entire crew, and commandeers the Enterprise in a vain attempt to destroy it. When that proves unsuccessful, he commits suicide, flying a shuttlecraft into it. That was an attempted TakingYouWithMe though.
*** "The Deadly Years" - With Kirk and the rest of the Enterprise senior staff incapacitated, Commodore Stocker takes command of the ''Enterprise'' and orders the ship into the Neutral Zone, against Star Fleet regulations.
*** "Whom Gods Destroy" - Garth of Izar, a former Starfleet Fleet Captain who develops megalomania and ends up in the asylum on Elba II.
*** ''Film/{{Star Trek VI|The Undiscovered Country}}'' - Several Federation and Klingon brass conspired to assassinate each other's heads of government.
*** Even ''Kirk'' veered towards this trope in ''Film/StarTrekIIITheSearchForSpock'' -- technically he ''did'' steal valuable Federation property to go to restricted space in order to complete a pet project, it just happened to be the right thing to do and a rather reasonable pet project.
** ''Series/StarTrekTheNextGeneration'':
*** Admiral Jameson violated the PrimeDirective by providing weapons to the leader of one side of a war in exchange for the Federation hostages he was holding, only to provide weapons to the other side in an attempt to maintain the balance of power. Granted, he was only a captain at the time, but decades later, the now-retired and infirm admiral took a massive overdose of a de-aging drug in order to be strong enough to face his former adversary again, in what turned out to be a revenge plot against Jameson for having helped perpetuate that war.
*** Retired Admiral Norah Satie ruthlessly investigated the crew of the ''Enterprise''-D, believing that there was a traitor among them. When her investigation proved fruitless she became rather unhinged, causing the saner Admiral proceeding over the events to excuse himself immediately and halt the investigation.
*** Admiral Kennely conspired with Cardassians to attempt an assassination of a Bajoran terrorist, blind to the fact that the there was no way the man could have committed the crime he was accused of.
*** Admiral Pressman conducted secret, dangerous, and illegal tests involving a Federation cloaking device and lied to other officers about it. Like Jameson, he was a captain at the time of the initial tests, but as an admiral he wanted to start them up again.
*** ''Film/StarTrekInsurrection'' - Admiral Dougherty is conspiring with an enemy power to remove an indigenous population from its homeworld in order to gain access to valuable resources. Possibly a subversion, since he was acting under direct orders from the Federation Council and tried to back out when things turned nasty.
*** In StarTrekExpandedUniverse, it's revealed that Dougherty was working with Section 31 on this.
** ''Series/StarTrekDeepSpaceNine'':
*** Admiral Leyton convinced the Federation President to declare martial law on Earth, carefully maneuvering his way into launching a coup. He was the KnightTemplar GeneralRipper type.
*** At least the more or less regular appearances of Admiral Nechayev earlier (though she still had her ObstructiveBureaucrat tendencies, this was actually part of a Dominion simulation, and her other appearances tended to center around the Maquis. [[ReasonableAuthorityFigure Admiral Bill Ross]] in the later seasons in the series presented Star Fleet's brass in a better light. As a big part of the Dominion War Arc, he practically became part of the Deep Space Nine crew, and the audience got to know and trust him.
** While Vice Admiral [[Series/StarTrekVoyager Janeway]] is not shown to be actively crazy onscreen during ''Film/StarTrekNemesis'', given some of her actions in the series it's not an unreasonable inference.
** ''StarTrekIntoDarkness'': Admiral Marcus [[spoiler:deliberately revived Khan in order to exploit his brutality]] and created a number of terrible weapons systems with his help. Marcus planned to start an "inevitable" war against the Klingons preemptively. He even went so far as to secretly build himself an unmarked, black starship twice the size of the ''Enterprise'' and designed purely for combat.
*** In the non-canonical [[spoiler:''Star Trek: Khan'']] comic, it's implied that most of these development were already underway before [[spoiler:the "enhanced"]] were found. [[spoiler:Khan]] did, however, take them UpToEleven, even building a portable transporter capable of sending a person to another star system, meaning it could be used to leapfrog pretty much anywhere without a ship. Why did [[spoiler:Khan]] do all this? Because [[spoiler:Marcus's people gave him LaserGuidedAmnesia, making him think he really was Agent John Harrison of Section 31]].
** Really, the list of admirals in ''Star Trek'' who are not either insane or [[SpearCarrier talking heads giving generic orders off a viewscreen]] is awfully short.
[[/folder]]

[[folder:Radio]]
* PlayedForLaughs in ''TheNavyLark'' with a parade of insane Vice-Admirals, and Commodores over the years. However, the actual [[EveryonecallsHimBarkeep Admiral]] in charge, while being a bit out of date and overbearing, was more often than not a BenevolentBoss and on more than one occasion the OnlySaneMan.
** That and his alcoholism dulls his interest in what's actually going on...
** Varied by episode, really. On at least one occasion - well into the 1970s - he was portrayed as not knowing that World War Two had ended.
* Major Bloodnok in ''The Goon Show'' has some insanity revolving around his gastric problems.
** Doesn't really fit here, though, being a) below Colonel and b) pretty savvy, just a lecherous crook with IBS.
[[/folder]]

[[folder: Roleplay]]
* French Fries in Roleplay/DinoAttackRPG. Where to begin? Remaining completely oblivious to the mounting tension between the two sides, he escalated what was once a debate between realists and idealists to whole new levels of violence (and didn't get punished until ''long'' after it was over). His favorite strategy is to send the men out of Dino Attack Headquarters walking very slowly toward a hoard of mutant dinosaurs. He tried to murder a HalfHumanHybrid who was working with the team for no reason other than being a hideous abomination, and he proudly boasted about killing one of the commanding elite agents' tamed mutant dinosaurs.
[[/folder]]

[[folder: Tabletop Games]]
* These turn up from time to time in ''TabletopGame/{{Warhammer}}''
* Many if not nearly all the officers of the Imperial Guard in TabletopGame/{{Warhammer 40000}}. Inquisitors (especially Radicals) also fit the description.
** It's actually kind of hard to tell when one is insane or just ruthless. While individual regiments may differ, standard Imperial Guard policy is that the life of a soldier is [[WeHaveReserves worth less than the weapon he was carrying]]. ''"Losses are acceptable; failure is not"''.
* Szuriel, Horseman of War, and Angel of Desolation is what happens when you combine the worst traits of a GeneralRipper and a ColonelKilgore with PsychoForHire, WeHaveReserves, WarGod and [[DemonLordsAndArchdevils Archdaemon]]. It isn't pretty.
* Many occasionally appear in ''BattleTech'' a good example is Khan Raina Montose of Clan Ice Hellion, she lead the Clan in their invasion of Clan Jade Falcons occupation zone. She orders her Clan push on their invasion even though their supply lines have been intercepted by the Falcons.
[[/folder]]

[[folder:Video Games]]
* Kefka from VideoGame/FinalFantasyVI was made conspicuously insane after an experiment GoneHorriblyWrong, and becomes obsessed with acquring personal power at all costs. Emperor Gestahl still trusts him as his right-hand man long enough for him to successfully usurp the power of the Warring Triad and set off TheEndOfTheWorldAsWeKnowIt.
* Admiral Greyfield (Sigismundo in the Europe version) in ''[[NintendoWars Advance Wars: Days of Ruin]]''.
* The Valuan admiralty of ''VideoGame/SkiesOfArcadia'' has a problem with this. Admirals Galcian, Ramirez, and [[MeaningfulName De Loco]] are all nuts (and evil), while Alfonso is incompetent (and evil) and Vigoro is... eccentric (and not so much evil as amoral). Small wonder the only two competent, sane admirals come off as the sympathetic villains of the lot...
* One of the personalities your generals can have in the ''TotalWar'' series is this trope.
* In ''Videogame/ShogoMobileArmorDivision'', you[[spoiler:r CO, Admiral Akkaraju, plans to use the Kato cannon against Avernus, disobeying High Command.]] In one of the two paths offered in the game, [[spoiler:you can choose to stop him]].
* Admiral Han'Gerrel from ''Franchise/MassEffect'' is of the GeneralRipper type, while his colleague Admiral Daro'Xen is this combined with MadScientist.
* Did I hear ''Franchise/StarTrek''? How about Admiral B'Vat in ''VideoGame/StarTrekOnline''? He wants to continue the war between the Federation and the Klingons by going so far as to ''find and unleash a second Doomsday Machine'' on the Federation just so that they have a reason to keep fighting. His past self from the ''Series/StarTrekTheOriginalSeries'' era is so disgusted with this, he tells the player character to go kill him.
** Not to mention Admiral Zelle [[spoiler: Undine Infiltrator]], [[DiskOneFinalBoss Romulan Colonel Hakeev,]] and [[TheEmperor Chancellor J'mpok]] of the KDF. We also have a borderline case with [[BloodKnight Admiral T'Nae,]] [[StrawmanHasAPoint though she typically makes up for it by being right.]] [[AvertedTrope Averted]] with [[BigGood Admiral Quinn,]] [[StarTrekVoyager Commander Naomi Wildman,]] [[FailureHero Captain Kurland,]] [[TheWorfEffect Admiral]] [[FourStarBadass D'Valk,]] [[DefectorFromDecadence all the Romulan Republic Admirals]], and [[SacrificialLion Admiral Zav Glasch Trem.]]
* In ''VideoGame/WingCommander'', Geoffrey Tolwyn is initially a {{Jerkass}} who doesn't get along with the PlayerCharacter. In the fourth game, he becomes the BigBad, trying to manipulate the Confederation into a war with a splinter government and preparing a eugenics program.
* ''VideoGame/GodzillaUnleashed'' has Admiral Gyozen go insane due to exposure to [[spoiler:Spacegodzilla's]] crystals, exacerbating his already irrational hatred of the kaiju. He realizes it, but then decides to attack anyway. even without the crystal on board his ship, he was still off his rocker due to seeing an UnknownRival in the Big G. Meanwhile, the King of the Monsters just wants to protect his turf.
[[/folder]]

[[folder:Web Original]]
* General Bowe in the ''Wiki/SCPFoundation''.
* Website/SFDebris treats Kathryn Janeway of the USS ''[[Series/StarTrekVoyager Voyager]]'' as a supervillain while she's only a captain, but in his review of ''Film/StarTrekNemesis'', she gets the full treatment, with a nearly three-minute monologue detailing how the entire plot of the movie including half the {{plot hole}}s was a part of her plan to take over the entire Alpha Quadrant.
[[/folder]]

[[folder:Western Animation]]
* Captain Matthew Marcus from ''WesternAnimation/ExoSquad''.
* Admiral Zhao from ''WesternAnimation/AvatarTheLastAirbender''. [[OmnicidalManiac He tried to kill the moon]], for crying out loud.
** Give him some credit, he ''successfully'' [[ItMakesSenseInContext killed the moon.]] Which does not mean it was a good idea or anything.
* The General and the lieutenant from ''WesternAnimation/CourageTheCowardlyDog'' are humorous examples of this.
-->'''The General:''' Good thing the money we paid that farmer with was made from experimental rocket-fuel! *Detonates cash*
* 25-star general Zapp Brannigan from ''{{Futurama}}''.
