An Arch Enemy, archfoe, archnemesis, or simply nemesis is some character's designated and most important enemy.

The Arch Enemy can be the BigBad, TheDragon, TheRival, an EvilCounterpart, or even a HarmlessVillain. The essential element is that, with them, ItsPersonal. Most typically, the Arch Enemy is a {{foil}} of some sort. For example, the Arch Enemy of the physically strong could be very smart. If the villain is the BiggerBad, his Arch Enemy commonly is the BigGood.

The Arch Enemy will stand out from the SuperHero's RoguesGallery -- there will be one opponent where the relationship to the hero and the motivations for battling them are more potent. These feelings may be [[UnknownRival one-sided]], felt more by the villain than the hero.

A hero's Arch Enemy is not necessarily the biggest threat to them. SelfDemonstrating/LexLuthor is considered Superman's Arch Enemy; {{Brainiac}} is smarter and {{Darkseid}} is vastly more powerful and [[SlidingScaleOfVillainThreat dangerous]], but for Lex - and, to a lesser extent, for Superman - it's ''personal'' between them.

Sometimes, the hero could have made the same choices as the Arch Enemy: the Arch Enemy is showing us what he could have become, as in the case of Batman and the Joker.

A hero may possess more than one Arch Enemy if more than one villain from his RoguesGallery stand out, or if a former Arch Enemy dies and new one comes in to the picture. As an example, consider Franchise/SpiderMan: the Green Goblin, Doctor Octopus, and Venom have all established themselves as recurring and iconic foes of Spider-Man, each of whom has been considered the wallcrawler's Arch Enemy at different points in time.

Lastly, remember that this generally refers to the enemy the ''hero'' considers to be his Arch Enemy, and ideally, it should be personal on both sides (though there are plenty of good "ButForMeItWasTuesday"-type Arch Foes out there). Especially in the case of a RoguesGallery, the hero is usually considered an Arch Enemy to ''all'' of his villains, but he doesn't treat all of them as such. Electro, Rhino, Scorpion, and others all consider Spider-Man their most hated foe, but compared to the Goblin, Venom, or Doc Ock, Spidey regards these guys more like superpowered nuisances. Also, remember that being the BigBad does not automatically make a villain the hero's arch enemy.

Beware of letting an Arch Enemy fall victim to VillainDecay.

See also BreakoutVillain, for those instances when a run-of-the-mill villain ascends to Arch Enemy status.

Not to be confused with various works known as ''{{Nemesis}}''. Also not to be confused with the [[Music/ArchEnemy Swedish death metal band]].

[[folder:Fan Fic]]
* In ''[[http://www.tfw2005.com/boards/transformers-fan-fiction/828948-transformers-meta.html Transformers Meta]]'', Hound and Barricade are this.
** So are Jazz and Starscream, but that's more one-sided.
* In the WesternAnimation/JackieChanAdventures fic ''FanFic/QueenOfAllOni'', Jade feels that Tohru is hers, based on her jealousy that HE became Uncle's apprentice and not her.
** [[TerminatorTwosome Drago and Karasu]] have shades of this as well.
** Right, one of Jade's CoDragons, becomes one to Viper.
* ''Fanfic/CalvinAndHobbesTheSeries'':
** Dr. Brainstorm sees Calvin as his - [[HarmlessVillain not so much the other way around, though.]]
** Also discussed in "Camping Trip Part 1":
--> '''Calvin:''' Hobbes, we have lots of mortal enemies! If this club only had ''one'' mortal enemy, then where would we be? Where would {{Superman}} be if he only had one super villain trying to take over the world every other day? Where would {{Spider-Man}} be if there was only one weirdo out there who managed to find enough time in his day to moonlight as an evil lunatic? Where would Franchise/{{Batman}} be if all he had to do is defeat one highly unrealistic villain in order to save... whatever it is he aims on saving? I mean, come on!
* ''FanFic/TheImmortalGame'' has [[CrazyAwesome Sir Unimpressive]] and [[MookLieutenant the Cadet]]. There's also an inverted case of UnknownRival in play as well, as the Cadet states that they were fierce rivals even before the war, something Unimpressive was unaware of.
* In the ''FanFic/PonyPOVSeries'', Shining Armor gains one in the form of [[GeneralRipper General-Admiral Makarov]] [[spoiler: (aka the [[HumanoidAbomination Shadow of Chernobull]])]], the BigBad of his side story.
* While [[AntiHero Rose]] is certainly the main character of ''Fanfic/EyesWithoutAFace'', she finds herself embroiled in a personal war between Twilight Sparkle and the [[BigBad Pie sisters.]]
* ''Fanfic/MyLittleCastlevania'' gives us [[TimeMaster Aeon and the Chronomage.]]
** By the end of the first book, this status is also bestowed upon Twilight Sparkle and [[WickedWitch Actrise]].
* ''FanFic/RenamonWho'' gives us [[WesternAnimation/JackieChanAdventures Valmont]] as one to [[Anime/DigimonTamers Rika Nonaka]].
* In ''Fanfic/TheLionKingAdventures'', the evil wizard Hago serves as one to Simba.
* In ''Fanfic/BoysUndSenshado'', [[Anime/GirlsUndPanzer Shiho Nishizumi]] and the Sakai family despise each other due to ideological conflicts, including the Sakais trying to get more people, including boys, involved in sensha-do. The dislike the Sakais have for Shiho only intensifies after she [[spoiler:disowns Miho, who is getting closer to Akio]].
* A large number of these can be found in ''FanFic/DiariesOfAMadman'', but particularly mention has to go to the relationship between Discord and the protagonist, Nav.
* ''FanFic/CodeGeassMegiddo'' has Lelouch and Suzaku. Suzaku still hates Lelouch for killing Euphemia and tarnishing her good name, but suppressed it for eight years after the Black Rebellion when Lelouch had his memories suppressed. Lelouch in turn resents Suzaku for betraying him and their friendship by giving him up to the Emperor, the father that abandoned him and Nunnally in a war zone, and suppressing pivotal memories to make him a loyal general for the empire, including making him believe Nunnally was killed alongside their mother. Needless to say, after Lelouch regains his memories, their next meeting has a gigantic blowout that devolves into a DuelToTheDeath.
** Several characters commenting on the relationship acknowledge that regardless of their former friendship, Suzaku truly is Lelouch's greatest enemy, even more so than his father. In fact, the narrative and the wiki suggest that they were ''destined'' to be enemies. It's to the point that many believe that if Lelouch does care about Suzaku, he may have to kill him in order to save him from himself.
* The ''Series/{{Neomorphs}} series has a few examples:
** [[TheDragon Guraff]] and Tobias (contrasting AntiVillain and AntiHero)
** Ax and [[EvilOverlord the Visser]]
** Jake and [[TheStarscream Mersa]]
* In ''Fanfic/KitsuneNoKenFistOfTheFox'', Yagura views Naruto as this, since Naruto's actions during the Nine Terrors' 365-day slaughter led to Yagura getting his facial scar. Naruto and Gaara also see each other as their greatest enemies [[spoiler:since it was Naruto's attempt to prevent Gaara's so-far-undisclosed schemes (and Yagura's intervention to stop Naruto) that caused the 365 days in the first place, and they gave each other a set of scars during that encounter--Naruto's whisker-marks are actually scars, while Gaara keeps his scar covered by his familiar tattoo]].
[[/folder]]

[[folder:Film]]
* Dr Evil is the Arch Enemy of ''AustinPowers'' [[spoiler: and his EvilTwin.]]
* Rene Belloq from ''Film/RaidersOfTheLostArk'', the EvilCounterpart to IndianaJones, is probably the closest thing he has to this.
* ''Franchise/StarWars'': Darth Vader is Luke Skywalker's Arch Enemy; meanwhile, Vader probably counted [[TheObiWan Obi-Wan]] as his.
* ''Franchise/PiratesOfTheCaribbean'''s Jack Sparrow and Barbossa. Once both men have died at least once, the conflict between them becomes more of a friendly rivalry.
** Commodore Norrington might also want to put himself in for consideration as Jack's Arch Enemy, though Jack seems to regard him as more of an obstacle and sometimes pawn.
** Cutler Beckett may qualify, as he has been the source of much/most of Jack's problems in his life. When using Jack's compass, it points him towards Jack, and Jack guesses that what Beckett wants most in the world is to see Jack dead.
* David Allen Griffin to Joel Campbell in ''Film/TheWatcher''.
* In ''Film/ThePrestige'', Borden and Angier start as friendly rivals, but the two become arch-enemies when one loses a wife. By the end, one has lost his wife and his life, the other reaches a PyrrhicVictory in besting his enemy but losing his brother and wife as well.
* In ''Film/TheMatrix'', Neo to Smith.
* Castor Troy for Sean Archer in ''Film/FaceOff''.
* [[NoNameGiven Harmonica]] and Frank in ''Film/OnceUponATimeInTheWest.'' The former has been hunting the latter for decades to put an end to his horrible crimes and to [[spoiler:avenge the death of his brother]].
* Since Bruce Willis turns out to be a comic book superhero in ''{{Unbreakable}}'', it only stands to reason that he'd have an arch-enemy. [[spoiler:One who is right under his nose.]]
* ''MysteryTeam'': Old Man [=McGinty=]
* In the FilmOfTheBook of ''Film/TheHitchhikersGuideToTheGalaxy'', Humma Kavula is this to Zaphod.
* Franchise/{{Godzilla}} is the Arch Enemy of the Japanese Self-Defence Force as a whole during the films where he's the villain ([[AntiVillain or]] [[AntiHero not]]). He also has his own recurring nemesis in [[HeroKiller King]] [[OmnicidalManiac Ghidorah]], who has battled him across eight films and four continuities, and whose [[LaughingMad gleeful]] [[ForTheEvulz malevolence]] provides a stark contrast with the Big G's more [[UnstoppableRage mindless rage]]. One could also make a case for [[EvilKnockoff Mechagodzilla]], Godzilla's only enemy to rival Ghidorah for number of appearances ([[BreakoutCharacter save for]] [[FriendlyEnemy Mothra]]) and ability to hurt Godzilla (the Heisei version of Mechagodzilla in ''Film/GodzillaVsMechagodzillaII'' is even stated to have been based on the recovered remains of Mecha-King Ghidorah from ''Film/GodzillaVsKingGhidorah'', essentially making it a combination of Godzilla's two arch-enemies).
** As far as Mothra goes, her arch-enemy is Ghidorah as well; she tolerates Godzilla's existence as long as he's not misbehaving too much, but when Ghidorah gets involved, she knows fully well that the whole planet she has sworn to protect is in danger. Epitomized by the ''Rebirth of Mothra'' trilogy, the [[Film/RebirthOfMothra first]] and [[Film/RebirthOfMothra3 third]] of which featured either Ghidorah or [[SuspiciouslySimilarSubstitute a close relative]] as the antagonist.
*** ''Film/GodzillaFinalWars'' made Gigan her arch-enemy instead so that the single coolest redesigned monster in the film could fight her during the climax while Godzilla dealt with the more plot-relevant antagonist--who was again, eventually revealed to be Ghidorah (this time in Kaiser form).
* In ''Franchise/{{Halloween}}'' no matter where [[SerialKiller Michael Myers]] goes, his psychiatrist Dr. Samuel Loomis will always be there to stop him.
* In ''Film/IronMan3'' the Mandarin finally makes his film debut as a DiabolicalMastermind out to destroy Tony. [[spoiler:Tony's true ArchEnemy -- and the true Mandarin -- is Killian, who is every bit as smart as Tony, but more ruthlessly manipulative and clever enough to hide in anonymity.]]
** The Iron Monger aka [[spoiler: Obidiah Stane]] may have a better claim to the title in this film series (even if he was only in the first movie). He had a very personal relationship with Tony until their goals ended up diverging. It's implied that his [[spoiler:betrayal]] may have mentally impacted him into the second movie.
* ''Film/XMen'':
** Pyro to Bobby.
** Victor Creed to Wolverine in ''Film/XMenOriginsWolverine''.
[[/folder]]

[[folder:Myth and Legend]]
* Loki and Heimdall in NorseMythology. Fittingly enough, they kill each other in Ragnarok. There's also Thor and Jormungandr who do the same.
* OlderThanDirt EgyptianMythology examples:
** Re/Ra and Apophis/Apep.
** Osiris and Set. Also Horus and Set.
[[/folder]]

[[folder:Newspaper Comics]]
* ComicStrip/FlashGordon has Ming the Merciless.
* ComicStrip/MandrakeTheMagician has Cobra.
* ComicStrip/DickTracy had Flattop. Flattop was KilledOffForReal decades ago, but he was so popular that [[LegacyCharacter Legacy Characters]] kept popping up afterward.
* PrinceValiant had Sligon, the tyrant who usurped his father's throne.
* BuckRogers had Killer Kane.
* The old melodrama spoof ''Hairbreadth Harry'' had the title character fighting a DastardlyWhiplash named Rudolph Rassendale--although Rudy was arguably the [[IneffectualSympatheticVillain real star of the strip]].
* Annie Mae the sea anenome to Pig in ComicStrip/PearlsBeforeSwine.
* [[ComicStrip/{{Peanuts}} Charlie Brown]] and the Kite-Eating Tree.
[[/folder]]

[[folder:Tabletop Games]]
* ''MagicTheGathering'': Urza and Yawgmoth is the best known Arch Enemy pairing, although there are dozens of individual hatreds. They've even released a variant ''named'' Arch Enemy, although that's dedicated more to a dynamic of BigBad vs. EnemyMine.
* While everyone in ''TabletopGame/{{Warhammer 40000}}'' [[ForeverWar will gladly fight everyone else]], there are some special rivalries and hatreds. The [[TheEmpire Imperium of Man]] is the staunchest enemies of the [[TheLegionsOfHell Forces of Chaos]], the [[SpaceElves Eldar]] fought the [[RobotWar Necrons]] once before and have taken it upon themselves to take them down now they have re-awoken, the [[ScaryDogmaticAliens Tau]] view the [[HordeOfAlienLocusts Tyranids]] as the single greatest threat to their survival (and they may not be far off from the truth), the Space Wolves and the Thousand Suns and the Ultramarines and the Word Bearers Space Marine chapters have intense rivalries stretching back millennia, the Chaos Gods [[WarGod Khorne]] and [[TheHedonist Slaanesh]] battle constantly to one-up each other, and the [[OurOrcsAreDifferent Orks]] [[TheUsualAdversaries are constantly this to]] [[BloodKnight everyone including themselves]].
** As an illustration of how deeply the Ultramarines vs Word Bearers hatred runs: in the HorusHeresy novels, it is revealed that the Ultramarines keep a precise count of time since the beginning of a battle - known as the Mark. The Mark of Calth, for the battle in which the Word Bearers first attacked the Ultramarines, will be left running until every Word Bearer is dead. Meaning that an Ultramarine can give you a precise count of how long it is they have wanted the Word Bearers to die, even ''ten thousand years'' after the original battle. Now ''that'' is enmity.
** On a smaller, more individual basis, there's [[ColonelBadass Commissar Yarrick]] and [[LargeAndInCharge Warboss Mag Uruk Thraka]]; Thraka thinks Yarrick is the [[WorthyOpponent greatest enemy he has ever fought]] and takes great enjoyment out of battling him, and Yarrick thinks Thraka is a hideous abomination and has vowed to kill him personally. They're still fighting to the death.
* Eric and the Dread Gazebo.
* TabletopGame/DungeonsAndDragons fourth edition setting, PointsOfLight, has a sourcebook detailing the realms of the gods, called ''The Plane Above''. In it it mentions certain gods who have a special, personal hatred for one another, giving the examples as [[CainAndAbel Bahamut vs Tiamat]], Avandra vs Zehir, and [[OurDwarvesAreAllTheSame Moradin]] vs [[{{Satan}} Asmodeus]]. With the exception of Bahamut and Tiamat, these examples are kind of out of the blue. Other examples include [[OurOrcsAreDifferent Gruumsh]] vs [[OurElvesAreBetter Corellon]] (which is taken from their ForgottenRealms counterparts, as well as The Raven Queen and Orcus, though Orcus is generally traditionally seen as the arch enemy of Demogorgon.
** Speaking of ''TabletopGame/DungeonsAndDragons'', Bane and Cyric. They hate each other worse than they hate any of the good gods.
* In the ''TabletopGame/YuGiOh'' card game, this seems to be the case between [[http://yugioh.wikia.com/wiki/D.D._Warrior_Lady D.D. Warrior Lady]] and [[http://yugioh.wikia.com/wiki/Warrior_Dai_Grepher Warrior Dai Grepher]]. They are seen fighting on several Spell and Trap Cards in a feud that started when she was Warrior Lady of the Wasteland and continued when he became Dark Lucious. The first one was [[http://yugioh.wikia.com/wiki/Simultaneous_Loss Simultaneous Loss]], but there were several others.
* As it is heavily influenced by comic books, TabletopGame/SentinelsOfTheMultiverse uses [[ArchEnemy Arch Enemies]] quite a bit. Every playable hero character has a Villain nemesis (though there are some cards in villain and environment decks that has nemeses ). Damage one deals to their nemesis is increased by one. For some pairs, this is one sided, such as the Argent Adept, a support hero who has few attacking powers, and his nemesis Akash'Bhuta, who has several ways to deal damage though her Limbs.
** The expansion Vengeance takes this a bit further. The five main villains have several targets in their decks that gain special effects that specifically weaken their nemesis if their nemesis is active. Calypso (a nemesis of Ra) reduces fire damage if Ra is active, which is the only damage type Ra deals.

[[folder:Real Life - Individuals]]
* Keith Baker is the Arch Enemy of Rich Burlew, creator of ''Webcomic/TheOrderOfTheStick'', due to his ''TabletopGame/{{Eberron}}'' setting being chosen over Rich's creation as the new campaign setting for TabletopGame/DungeonsAndDragons. When Keith wrote an article for Rich's site, it was [[LampshadeHanging lampshaded]] ''twice'', and there have been [[TakeThat numerous jokes at Eberron's expense]] within the comic.
-->'''Durkon:''' "Meh. It could be worse, ye know."
-->'''Vaarsuvius:''' "Oh?"
-->'''Durkon:''' "They could have magic trains."
-->'''Vaarsuvius:''' "Point taken."
** And Baker also turns up in StartOfDarkness (the trope namer, that is) as one of Xykon's rivals for the position of second-in-command to the Unholy Master early on in the book.
* Bobby Kennedy and UsefulNotes/LyndonJohnson hated, ''hated'' each other with a passion. Bobby felt Johnson was a devious coward, Johnson thought Bobby was a foul tempered "little shit." Intensified tenfold after [[UsefulNotes/JohnFKennedy JFK's]] [[WhoShotJFK assassination]].
** Also, [[TheFogOfWar Robert McNamara]], the Secretary of Defense and a close personal friend of Bobby's who only got ''closer'' to him after Jack's assassination, got caught in the crossfire. This may have influenced some of Johnson's decisions in UsefulNotes/TheVietnamWar.
* Mark Gottlieb, the rules manager of ''TabletopGame/MagicTheGathering'', is the Arch Enemy of Mark Rosewater, the game's head designer. That's according to [[FanNickname MaRo]], at least, but he's [[CloudCuckoolander nuttier than a bag of squirrels]].
* [[http://en.wikipedia.org/wiki/Othniel_Charles_Marsh Othniel Charles Marsh]] and [[http://en.wikipedia.org/wiki/Edward_Drinker_Cope Edward Drinker Cope]] were two of the major pioneers in the field of paleontology and between them identified over 142 new species of dinosaurs. Unfortunately, they hated each other with a passion and each became obsessed with defeating the other and proving himself the better scientist. Their frenzied race, known as the [[http://en.wikipedia.org/wiki/The_Bone_Wars Bone Wars]], extended over fifteen years and ended in a virtual stalemate, and both men were nearly bankrupted by the effort. In the end, they both made enormous contributions to the study of dinosaurs, committed any number of shady deeds to undermine each other, and ended up in the poorhouse. NotSoDifferent, indeed.
* UsefulNotes/JohnAdams and UsefulNotes/ThomasJefferson, the second and third presidents respectively, were this; after UsefulNotes/GeorgeWashington left the office, these two formed bitterly divided parties against each other. Ironically, due to how voting worked at the time, Jefferson wound up as vice president to Adams when he entered office, making things even worse than they were before. After both of their terms as president were over, however, they went on to become good friends.
** Actually, they were good friends before Adams became president, having collaborated on the Declaration of Independence and worked together overseas. But when their political ideologies started to diverge, their relationship fell apart. Luckily they patched it up when they retired.
** Then there was Aaron Burr and UsefulNotes/AlexanderHamilton, a political and personal rivalry that actually ended with Burr (then Vice-President of the United States) [[http://en.wikipedia.org/wiki/Burr-Hamilton_duel killing Hamilton in a duel]].
** More on 19th Century American politics - UsefulNotes/AndrewJackson vs. UsefulNotes/HenryClay; a rivalry that started for political reasons when Clay allegedly cheated Jackson out of the presidency in 1824 by making a "corrupt bargain" with UsefulNotes/JohnQuincyAdams and which later turned personal in 1828 when Clay organized and carried out the slander campaign which led to the death of Jackson's wife, Rachel. The blood feud lasted for over twenty years!
** Another example from US politics: UsefulNotes/BillClinton and Newt Gingrich.
** In the current Congress, John Boehner vs. Nancy Pelosi and Mitch [=McConnell=] vs. Harry Reid.
* In the related area of American campaign strategizing and punditry, James "the RaginCajun" Carville and Mary Matalin, respectively Democratic and Republican campaign [[TheStrategist strategists]] and pundits ''extraordinaire'', have called themselves arch-enemies on several occasions. They're quite right: they repeatedly found themselves fighting campaigns for opposing candidates in UsefulNotes/TheEighties all the way up to 1992, when they were high-ranking members of the Clinton and Bush campaign staffs, respectively. Then [[DatingCatwoman they got married in 1993]]. OppositesAttract, one supposes... (They still appear opposite each other from time to time on Creator/{{CNN}} and other networks to bash each other's political heads in. One wonders what their daughters--around whom they do not talk about politics--think of all this.)
* IsaacNewton and Gottfried Leibniz fought for years over who invented calculus.
** Newton also hated Robert Hooke with a passion. It's widely believed that his famous statement "If I have seen far, it is because I have stood on the shoulders of giants" was a [[TakeThat swipe at Hooke]], who was [[TheNapoleon notably short]].
* [[Series/BarneyAndFriends Sheryl Leach]] and [[Series/SesameStreet Caroll Spinney]] have each gone on record criticizing the other's show.
* Liberal William Lyon Mackenzie King and Conservative Arthur Meighen were bitter rivals in university, and the bad blood between them carried over when they both went into politics. Both men would serve as prime minister of Canada and led their parties against each other, but this trope was arguably subverted because King repeatedly wiped the floor with Meighen in their political {{Curb Stomp Battle}}s.
* Half a century earlier, a much more balanced version of this played out in Britain between UsefulNotes/WilliamGladstone and Creator/BenjaminDisraeli. Gladstone was a vaguely anti-imperialist Liberal (until he took office, whereupon the empire actually nearly grew twice as much as it had under Disraeli), a devout Christian very involved in social causes, and very much a man of ideas. Disraeli was a raw politician (though not without principles), ethnically Jewish, not a particularly serious Anglican, something of a hedonist, and a Conservative imperialist extraordinaire (he was responsible for making Queen Victoria ''Empress'' of India). For her part, the Queen loved Disraeli (and not just for making her an Empress) and hated Gladstone ("He always speaks to me as though I were a public meeting."); she made Disraeli an Earl but didn't even give Gladstone the courtesy of recommending a successor when he retired (and picked his least favourite candidate out of spite). Gladstone was frugal and very good with money (becoming Chancellor of the Exchequer four times, including twice as his own Chancellor); Disraeli was a bit of a spendthrift and kept having to write {{Romance Novel}}s and other penny-dreadfuls to stay solvent. They led their parties against each other in several elections in the late 19th century, more or less taking turns governing the country and trading insults: Disraeli mocked Gladstone's nickname, GOM (the "Grand Old Man"), as really meaning "God's Only Mistake." For his part, Gladstone [[NeverSpeakIllOfTheDead called Disraeli shallow even in death]]. These two men ''hated'' each others' guts with a passion not seen since in British politics.
** While not to the same level as the two mentioned above, the rivalry between Labour leader Harold Wilson and Conservative leader Edward Heath dominated British politics for a decade.
* [[TheRomanRepublic Marius and Sulla, Caesar and Cato, Crassus and Pompey, Antony and Cicero, Antony and Octavian]].
* Creator/HunterSThompson, author of ''Literature/FearAndLoathingInLasVegas'', hated UsefulNotes/RichardNixon almost more than words can adequately describe. When he told Nixon this, Nixon said "Don't worry. I, too, am a family man, and we feel the same way about you." To give you an idea of just how much Thompson hated him, observe [[http://www.counterpunch.org/thompson02212005.html this article]], written just a few days after Nixon's death.
-->''If the right people had been in charge of Nixon's funeral, his casket would have been launched into one of those open-sewage canals that empty into the ocean just south of Los Angeles. He was a swine of a man and a jabbering dupe of a president. Nixon was so crooked that he needed servants to help him screw his pants on every morning. Even his funeral was illegal. He was queer in the deepest way. His body should have been burned in a trash bin.''
* UsefulNotes/NikolaTesla and ThomasEdison
* Holy Roman Emperor Charles V and Ottoman Sultan Suleiman the Magnificent, who saw themselves as the protectors of their respective faiths and battled one another for control of the Mediterranean for their entire lives. Their chief admirals, Andrea Doria and Khizr Barbarossa became archenemies by association.
** Francis I of France has also been seen as Charles' arch-enemy, and to a lesser extent, Francis and Charles also both had considerable personal rivalries with Henry VIII of England.
* Czar Peter the Great of Russia and King Charles XII (Carolus Rex to ''{{Sabaton}}'' fans) of Sweden, who spent all of Charles' adult life at war with each other. It was noted that as long as Charles ran Sweden and Peter ran Russia there would be no chance of peace, so much did they hate each other.
* Reinhard Heydrich, Deputy Leader of the [=SS=] and founder and head of its insidious intelligence branch, the [=SD=], was TheRival and archenemy of Admiral Wilhelm Canaris, the head of German Military Intelligence (the Abwehr). Heydrich was a DeceptiveDisciple to Canaris; Heydrich had a lifelong hatred of naval officers (due to being fired by the navy for dishonourable conduct- namely, falsely promising a woman he'd marry her to get her in bed; said woman was the daughter of an admiral) but he made an exception for Canaris, who became his friend, mentor and his neighbour. Canaris in turn liked and respected the intelligent, ambitious, and multi-talent Heydrich- until the mid-to-late 30's, when he gradually realized that Heydrich was also a murderous psychopath indifferent to terror and mass murder of innocent people, which went hand-in-hand with his growing contempt for UsefulNotes/NaziGermany as a whole and led to Canaris becoming a leader of LaResistance (though, like most conservative enemies of the regime, he hoped to make Germany a large nation at the expense of some neighbours before getting rid of it). Heydrich seemed to regard Canaris as a FriendlyEnemy- he liked him, but as a ruthless careerist he had zero qualms about plotting his downfall and death; he knew full well of his anti-Nazi activities and was building a case against him at the time of his assassination. Canaris may have had a hand in Heydrich's death, and the eventual arrest and execution of Canaris was built in large part on evidence collected by Heydrich.
* Muhammad Ali and Joe Frazier. Three fights, with Frazier winning the first, and Ali the second, before the bitterly contested Thrilla in Manila which Frazier would always insist he could have won had the referees allowed the bout to continue. During their rivalry, and for years afterwards, the well-spoken flashy Ali would belittle and mock the completely uneducated Frazier, who was largely unable to defend himself, who in turn became ever more bitter, openly gloating over Ali's development of Parkinson's. The two did eventually reconcile before Frazier's death, with Ali attending his funeral and displaying an appropriate respect.
* James Randi and Sylvia Browne. The two almost seemed destined to become enemies, with Browne being a notoriously inaccurate and yet somehow successful [[PhonyPsychic professional psychic]] who also was (or rather claimed to be) a devout Christian; whereas Randi is a famous paranormal debunker with a 100% success rate, and an unapologetic atheist. They had a feud since Randi offered her the chance to prove her powers under laboratory conditions in TheEighties and she refused, on the basis that as an atheist he was not qualified to judge her. Since Randi has outlived her, he seems to have won.
* Creator/StephenKing and Creator/DeanKoontz do not think much of each other. The fact they are on the opposite sides of the political spectrum probably plays a part in this.
[[/folder]]

[[folder:Real Life - Countries and Institutions]]
* England and France have historically been enemies that never got along and warred constantly. Nowadays they're kinda like VitriolicBestBuds instead.
** Similar with France and Germany, [[HeterosexualLifePartners though now they get along better than England and France ever could.]]
** Sweden and Denmark also have this. [[http://satwcomic.com/the-law-is-the-law Just look at the way]] [[http://satwcomic.com/nordic-brothers they treat each other!]]
** Norway and either Sweden or Denmark, whoever Norway was not in an alliance with.
** Sweden is this to the rest of the Nordics(Except Iceland, its either Denmark or the US).
** More seriously, Russia is this to Sweden and Finland both.
* Ancient Athens and Sparta, even as there were some times that they helped one another.
* The U.S. and the Soviet Union during the UsefulNotes/ColdWar. Became more like [[TheRival rivals]] during [[http://en.wikipedia.org/wiki/Detente Detente in the late '60s and '70s]], but escalated back into archenemies during the '80s until the Soviet Union's fall in 1991. These days they are on more or less good terms, though Russia has a habit of blowing a lot hot air every now and then, but it's treated more like an UnknownRival now.
** The US-Soviet rivalry is odd in that the recent rise of China as an economic superpower seems to have made some Americans [[WhyWeAreBummedCommunismFell nostalgic over the Soviet Union]]. The recent Russian spy scandal was rife with jokes about how the FBI and CIA were ecstatic about a return to the good old days.
** Ironically, the United States had good relations with TsaristRussia. Russia was officially neutral during the UsefulNotes/AmericanRevolution, but nevertheless indirectly helped it by supplying arms to France and Spain, both of whom were allied with the colonists. Russia was also the only European country to declare support for the Union during the American Civil War (because they thought an intact America would stand a better chance of counterbalancing the power of UsefulNotes/TheBritishEmpire), although they didn't actually intervene. The Russians also sold Alaska to the U.S. in 1867, and boy are the Americans glad that the Russians didn't have that land during the Cold War.
* Argentina and Great Britain over the Falkland Islands.
* The Roman and Persian Empires battled each other for ''centuries'', but Rome's traditional Arch Enemy was Carthage, as per ''Literature/TheAeneid''.
* Poland and Germany have long detested one another. Luckily, this seems to be winding down what with the end of the two [[UsefulNotes/WorldWarTwo big]] [[UsefulNotes/ColdWar wars.]]
* Greece and the Ottoman Empire. Greece and Turkey. China and Japan. Japan and South Korea, Israel and Palestine. Really, it could go on and on...
** Let's see, North Korea and South Korea. North Korea and Japan. North Korea and United States. North Korea and anyone in the EU who is not Switzerland or Sweden.
** And now North Korea and China, considering [[TooDumbToLive North Korea's]] [[BullyingADragon recent actions.]]
* The United States Republican and Democratic parties in general and their presidential nominees every four years.
** For that matter, the North and the South of America. Some don't really care, but attitudes for both range from Southerners viewing Northerners as obnoxious "left wing loonies," and Northerners viewing Southerners as ignorant rednecks. There are also some individuals in the South who still are bitter about losing UsefulNotes/TheAmericanCivilWar, and will react quite angrily if questioned on this point. Likewise, some Northerners have never gotten over the incident.
* India and Pakistan. Three major wars and one minor conflict and several close calls and both sides have nukes? Archenemies.
** India and Japan are petitioning for permanent security council seats, while Pakistan and Korea are in committee to vote them down. This would strangely make Mexico a burgeoning rival for Brazil.
* Australia and New Zealand - but only in the sporting arena, elsewhere we're VitriolicBestBuds at worst, BestFriends when having to be part of TheSquad at best...
* In any [[http://en.wikipedia.org/wiki/Duopoly duopoly]], the two dominant companies could be considered this.
** Pepsi and Coke
** MarvelComics and DCComics are a subversion: while they compete with each other, they generally work together to bolster the comics market, share most of the same customer base, and often [[RivalsTeamUp team up]] for [[{{Crossover}} crossovers]].
** Creator/{{Nintendo}} and {{Sega}}, during the fourth generation of video games.
*** Sega was Nintendo's arch-enemy before it stopped making its own gaming consoles. Nowadays we have the three-way archenemies of Nintendo, Creator/{{Sony}}, and [[Creator/MicrosoftStudios Microsoft]].
*** Being that Nintendo and Sony were originally going to work together on using CD technology in future consoles, [[https://www.youtube.com/watch?v=ryi1QBA6XyI&t=5m28s leading to Nintendo's betrayal]] in instead working with [[PhilipsCDi Philips on the CDi]], it could also be considered a case of WeUsedToBeFriends and ItsPersonal on Sony's part.
** Disney, being a multi-media conglomerate, has different arch-enemies in different fields
*** Disney and WarnerBrothers were this in the field of animated shorts before that format mostly disappeared. Nowadays, there's a bit of this between DisneyToon Studios (which makes films, mostly [[DirectToVideo direct-to-video]] ones) and Walt Disney Television Animation on one side vs. and Warner Bros. Animation (which also does TV shows and direct-to-video films) on the other side.
*** And since Disney owns Marvel now and DC has been owned by Warner Bros, the Marvel/DC rivalry takes on an extra layer.
*** ToonDisney vs. {{Nicktoons}} before Toon Disney ceased to exist.
*** In TV in general, Disney channel vs. Nickelodeon
*** DisneyXD vs. {{Nicktoons}}, or DisneyXD vs. Creator/CartoonNetwork [[ScrewedByTheNetwork Well, until CN abandoned serious action cartoons.]]
*** In theme parks, Disney World vs. Universal Studios
** {{Pixar}} and Creator/DreamWorks Animation
* Nickelodeon vs Cartoon Network.
* FoxNewsChannel (Conservative) vs Creator/AlJazeera English (Liberal).
* On a more regional level, Al Jazeera (Qatar) vs Press TV (Iran).
* The African countries of UsefulNotes/{{Ethiopia}} and UsefulNotes/{{Somalia}} have had more than their share of spats over the centuries.
* UsefulNotes/AdolfHitler (and by extension UsefulNotes/NaziGermany) saw the Jews as his archenemy. By the time he died, the feeling was definitely mutual.
* Armenia and Azerbaijan, or Armenia and Turkey. The former is India and Pakistan on a small (and not world-ending) stage.
* UsefulNotes/{{Egypt}} and UsefulNotes/{{Israel}} apparently have the lowest approval ratings of each other than any other pair of countries.
* UsefulNotes/{{Denmark}} and UsefulNotes/{{Sweden}} have apparently fought more wars than any other two countries.
* Given their long shared history, ''everybody'' in South-East Asia could be argued to be each other's archenemies. Malaysia and Indonesia fought a confrontation over the formation of the former, Singapore has at best TeethClenchedTeamwork with Malaysia, Malaysia butts heads with Thailand and the Philippines over Islamic insurgencies along their borders, Vietnam and Cambodia still aren't on good terms after the Vietnam-Cambodia war, Vietnam jockeys with Indonesia in ASEAN over who's the regional power, everyone fights over the Spratly Islands, and nobody cares about Myanmar or Laos.
