-> ''"[[BadassBoast I am not concerned with us all, just myself]]. And believe me, [[DangerouslyGenreSavvy I shall be perfectly fine]]. Now, sit, please." ''
-->-- '''Artemis Fowl II'''

A series of novels written by Creator/EoinColfer.

Originally, the tale of an Irish [[TeenGenius pubescent]] [[VillainProtagonist evil]] [[InsufferableGenius genius]] and his efforts to [[AmbitionIsEvil acquire money and power]] by exploiting the [[BeneathTheEarth secret underground world]] of [[TheFairFolk fairies]] living [[DepartmentofRedundancyDepartment beneath the world]] using both magic and [[AppliedPhlebotinum advanced supertechnology.]] In later books in the series, he becomes a more benevolent fellow, working cooperatively with the fairies to curtail human mischief. The series takes cues from suspense, [[ActionAdventureTropes action]], [[TheCaper "heist"]] crime films, and ''Film/JamesBond''-esque spy movies and transplants them into a [[UrbanFantasy modern fantasy setting]].

The series contains eight novels, the final one having been released on July 10th, 2012.

#''Artemis Fowl'' (2001)
#''Artemis Fowl: The Arctic Incident'' (2002)
#''Artemis Fowl: The Eternity Code'' (2003)
#''Artemis Fowl: The Opal Deception'' (2005)
#''Artemis Fowl: The Lost Colony'' (2006)
#''Artemis Fowl: The Time Paradox'' (2008)
#''Artemis Fowl: The Atlantis Complex'' (2010)
#''Artemis Fowl: The Last Guardian'' (2012)

There are also two short stories that are available in the companion book ''The Artemis Fowl Files'', and four graphic novels that appear to form a different canon to the prose (there were other [[ComicBookAdaptation less obvious changes]], but one is listed under RaceLift).

A [[http://www.ign.com/articles/2013/07/29/disney-harvey-weinstein-team-for-artemis-fowl-movie-adapatation film adaptation]] was announced after being stuck in DevelopmentHell. It will be produced by [[Creator/{{Disney}} Walt Disney Pictures]] and Creator/TheWeinsteinCompany.

!!Provides examples Of:

* AccidentalHug: Butler does this to Artemis in the fifth book and then pulls away, embarrassed. (Artemis doesn't mind.)
* ActionGirl: Holly and Juliet.
* AdjectiveAnimalAlehouse: The Sozzled Parrot.
* AffablyEvil:
** Artemis starts out this way, being loath to actually kill anyone (fine with kidnapping, psychological warfare and an occasional bomb or two, though), and very cordial with the negotiators, as well as keeping his words. Also while he is not exactly good, he does care for his allies and family.
-->"... every inch the gracious host, albeit a sinister, evil, determined one."
** FauxAffablyEvil: Turnball Root, who compliments Holly right after kidnapping her. He doesn't really care about ''anyone'' except for his human wife Leonor (and even then he kept her in thrall so that she wouldn't ever think of leaving him) and is willing to kill his own trusted lackey if needed without a hint of remorse.
* AirVentPassageway: in ''The Arctic Incident''. Artemis has to crawl through a duct filled with fuel for the building's plasma weapons. Before his helmet runs out of air. Without being able to see where he's going. Knowing full well that if anyone turns on the plasma cannons, he's toast. Not to mention that once he gets out, he has to be sprayed with anti-radiation foam or he'll likely develop cancer.

%% AlasPoorVillain was moved to the YMMV tab. Please don't add it back here.
%%
* AllTrollsAreDifferent: In this case, ten-feet-tall gorilla-ish tunnel-dwelling monstrosities with poisonous tusks. And dreadlocks.
* AlmostOutOfOxygen: In the second book and again in the seventh.
* AlwaysChaoticEvil: Goblins and trolls, although the latter are mostly portrayed as just animals, and the former is incredibly, ''incredibly'' stupid. They're directly stated to be as smart as ''rats''.
** Strangely averted with the demons, as only Leon Abbot is shown to be actively evil and willing to use magic to brainwash others.
* AmnesiacDissonance: An odd case. After recovering from his mind-wipe, Artemis sees that he was regressing to his old criminal ways, as he had predicted he would. After all, his character growth was a result of his experiences with the People...so removing all memory of his experiences with them takes away all the good it did him. Holly is visibly nervous when he brings this up because she knows how terrifyingly amoral he used to be.
* AmnesiacResonance: After Artemis's mind-wipe, he admires a painting, ''The Faerie Thief''. He acknowledges that the fairy in the painting can't enter a human dwelling without permission (one of the laws fairies live by), then wonders how and why he knew that. Later, when an assassination attempt against him fails, he recognises the blue light from the incident as a Blue Rinse, a fairy superweapon similar to a bio-bomb.
* AnachronismStew: In ''The Time Paradox'', Artemis goes back to two years before the first book (which was published in 2001, and uses human technology from that time). Yet, the young Artemis has a mobile phone that can be used to surf on the Internet, be connected to a beamer, has a blacklight to test money and an ''X-ray scanner''. He uses his laptop to send a video message to every Extinctionist's phone, and all of them can watch it. Also, Kronski pays Artemis in bills of 500€, while the euro hadn't come into use (as a physical currency) until a few years later.
* AncientAstronauts: The reason Artemis translates the fairy language so easily is that it is similar to Ancient Egyptian and Artemis theorizes this is because the Egyptians borrowed it from the fairies.
* {{Annoying Younger Sibling}}s:
** As of book 6, [[spoiler: Myles and Beckett Fowl]].
** [[CuteBruiser Juliet]] to {{B|adass}}utler in the first book, before she TookALevelInBadass.
** Grub Kelp to his superior officer Trouble. Corporal Grub has a bad habit of forgetting that Trouble is "Captain" while they're on duty; even when he remembers, he seems to think that "Mummy says" trumps rank. At his best he needs cajoling; at his worst he gives the impression that "Mummy says" is the reason such an utter liability is even allowed in the LEP, let alone on the squad of a Captain in good standing like his brother.
* AnotherStoryForAnotherTime: The first book's narrator has this as a catchphrase, with the stories eventually becoming sideplots in later books.
* AntagonistInMourning: Holly, briefly, in the first book when Fowl Manor is bio-bombed and it appears that NoOneCouldSurviveThat. Root and Mulch mutually on separate occasions.
* AntiVillain: Artemis Fowl, before he became the hero. Likewise with Butler, who's just doing his duty.

* ArmourPiercingQuestion: "Artemis... Isn't that a girl's name?"[[labelnote:Answer]]while the Greek goddess Artemis was indeed female, Mr. Fowl is quick to point out that the name itself is genderless in Greek.[[/labelnote]]
* ArsonMurderAndJaywalking: "The Fowls had held on to Fowl Manor over the years, surviving war, civil unrest, and several tax audits."
%%
%% Artistic License - Physics has been deleted as the Neutrino rifles do not actually fire neutrinos but lasers.
%%er bullets at home?!
* ArtisticLicenseBiology: Early in, Holly Short has a CharacterFilibuster denouncing sewage treatment as a [[GaiasLament horrible violation of Mother Earth]], inspiring FridgeHorror in readers familiar with modern Germ Theory. However, the filibuster wasn't something the reader was supposed to agree with but rather a demonstration of BlueAndOrangeMorality. The fact that elves think putting your restroom indoors is unhygienic was supposed to reinforce this.
* ArtisticLicensePhysics: Book 2: Why does Artemis have to ''swim'' through the plasma powering the security systems, unless it's really dense. As well as how it can be radioactive in the first place.
** From the same book, the Softnose laser rifle is described as a mining tool re-purposed as a weapon. It can be powered by an AA battery, with enough energy for 6 shots. It is also equipped with a suppressor that ''slows down the laser beam'' so that it can bore into the target instead of simply vaporising the surface.
** There's something in every book really. The infamous Biobomb is described as firing blue light that only kills living beings, while leaving material unaffected. Even if we assume it's not really the visible light that is the damaging agent, in Opal Deception Holly uses her helmet to shield the bomb, and when it proves insufficient she engages her wings and [[OutrunTheFireball races against the rays!]] And succeeds! She'd have to be going FTL to manage this.
* TheAtoner: Artemis is a [[SplitPersonality rather serious]] case in book 7.
** This continues into Book 8 and is a factor in [[spoiler: Artemis's heroic sacrifice.]]
* AuthorAppeal: The narrative would often go into the horrific outcomes of pollution and how HumansAreTheRealMonsters for all their environmentally destructive ways. Also for killing animals for consumption and espousing the virtues of the green and vegetarian lifestyle of the fairies. On a lighter note, he also enjoys going into descriptions of the various high-tech gadgets that appear.
* AppliedPhlebotinum
* AwesomeMcCoolname
** Trouble Kelp invoked this when chose his new first name at his LEP graduation ceremony. He's so awesome even Holly respects him.
** "Chix Verbil" counts as well, though the character himself is a bit of a slouch.
** And of course, the title character.
* AwesomenessByAnalysis: Artemis's forte.
* {{Badass}}:
** Butler can win a toe-to-toe fight with a troll.
** Holly is pretty much the LEP's best pilot ever, on top of being an athletic ActionGirl and a great markswoman.
** Juliet put a jade ring in her hair and beats people down with that, because she can just toy around with less awesome than her brother.
* BadassBoast: Doubles as SugarWiki/{{Heartwarming Moment|s}}, the ending of ''Eternity Code'':
--> Together we will be unstoppable.
** From the last book, Butler: "I am Butler. Everything I say sounds tough. Now, get out of the lake, fairy."
* BadassInDistress: In the first book, when Holly gets kidnapped by Artemis [[spoiler: she uses a cot to ''smash through concrete'', plants an acorn she snuck in, uses a loophole in an eye-to-eye command to go around the house, neutralizes Juliet with the ''mesmer'', and punches Artemis. And just when you think things can't get worse for the kidnappers, [[OhCrap a troll comes in . . .]] ]]
%%
%% BadassDecay was moved to the YMMV tab. please don't add it back here.

* BadGuyBar: The Sozzled Parrot in Atlantis Complex.
* BatmanGambit:
** In the first book, where Artemis is trying to kidnap a fairy. He knows they have to go to a specific place at a specific time to do a specific thing, but if no one shows up (a very likely outcome) then he just sits in a tent all night. It's mentioned that this is exactly what happens for four months.
** Also first book: Cudgeon sends in the troll banking on the humans calling for help before it kills them, thus inviting the LEP inside.
** Also first book: Artemis' entire plan revolves around [[spoiler: 1. the fairies using a time stop, and 2. the fairies noticing a flaw in his orders which would allow them into the manor once he was dead. ]]
** Second book: [[spoiler: Foaly gets Cudgeon to admit to his EvilPlan on tape]] because he knows his mark will want to brag about it.
** Used by Artemis twice more against Opal in ''The Opal Deception'' and ''The Last Guardian''. [[spoiler: The latter example is especially notable as Artemis essentially gets Opal to push the 'off button' on her doomsday spell by predicting her rampant narcissism.]]
* BattleButler: In its purest form, Butler.
* BavarianFireDrill: Juliet pulls one by joining a SWAT team in book three. Artemis also pulls them frequently.
* BeneathTheEarth: Haven City
* BigBad: [[VillainProtagonist Artemis Fowl]] in ''Artemis Fowl'', [[BigBadDuumvirate Briar Cudgeon and Opal Koboi]] in ''The Arctic Incident'', [[CorruptCorporateExecutive Jon Spiro]] in ''The Eternity Code'', [[EvilOverlord Leon Abbot]] in ''The Lost Colony'', [[spoiler:[[AxCrazy Opal Koboi]]]] in ''The Time Paradox'', and [[spoiler:[[CainAndAbel Turnball Root]]]] in ''The Atlantis Complex''. [[AxCrazy Opal Koboi]] also serves as the Big Bad in ''The Opal Deception'' and ''The Last Guardian''.
** BigBadEnsemble: [[IHatePastMe Young Artemis Fowl]] forms one with [[spoiler:Opal Koboi]] in ''The Time Paradox''
** TheBigBadShuffle: In ''The Lost Colony'', [[ChildProdigy Minerva Paradizo]]'s plot to [[ForScience capture and study]] a demon becomes subsumed by [[DragonWithAnAgenda Billy Kong]]'s desire to avenge his older brother (who claimed to be fighting demons to cover up his gang activities), which is in turn overshadowed by Leon Abbot's treacherous control of Hybras.
* BigBrotherInstinct: Even though Grub is practically the poster boy for AnnoyingYoungerSibling, Trouble does protect him in life-threatening situations.
* BigEater: Mulch.
* BilingualBonus: There is a dwarf named Gotter Dammerung. Götterdämmerung is a German word which has been adopted into English to refer to something with a disastrous conclusion. Can also be a case of PunnyName.
* BookEnds: [[spoiler:The final lines of ''The Last Guardian'' are Holly reciting the opening to the first book verbatim.]]
** [[spoiler: And a few lines before that, we get a CallBack to Artemis and Holly's first encounter.]]
** [[spoiler: The first book is about the fairies sieging a human-held Fowl Manor and the last is about the main group sieging a fairy-held Fowl Manor.]]
* BoxedCrook: Mulch Diggums, frequently.
* BraidsOfAction: Juliet Butler
* {{Brainwashed}}, BrainwashedAndCrazy: The ''mesmer'' power is possessed by all fairies (and some humans).
* BrainsAndBrawn Artemis and Butler, each extremely gifted in his area. Myles and Beckett in book 8, the first being a genius toddler on his way to follow the steps of his brother, the second exceptionally strong and agile, but with an intelligence average for his age.
* BriarPatching: When Spiro orders Pex and Chips to kill Mulch, Mulch goads them into burying him alive... which doesn't bother him in the slightest, since he's a naturally subterranean fairy.
* CadreOfForeignBodyguards: Artemis is guarded by the {{B|attleButler}}utler family, of Caucasian (as in, from the Caucasus) descent.
* CameraSpoofing: In ''The Eternity Code'', [[spoiler:Foaly spawns holographs to make it seem like all the guards were knocked out from sleeping gas, and Artemis is there against his will. There were only two guards, and the holographs and Artemis don't show up on the camera. At all.]]
* CanisLatinicus: The American editions turn the Fowl family motto into this.
* CantTakeAnythingWithYou: In order to simplify things in the timestream, N[[superscript:o]]1 insists that Holly and Artemis strip before he sends them back in time, much to their chagrin. They bargain him down to just underwear. It's a little bit embarrassing for them.
* TheCaper
* CaptainObvious: Demons have lived in a different dimension from ours for thousands of years, only learning of human customs and culture through one trashy romance novel, which they take as a sort of Bible. N[[superscript:o]]1, a young demon/warlock we first meet in ''The Last Colony'', was particularly interested in the human world, so when he finally gets transported there, he takes great pleasure in pointing out the meaning of human expressions, despite the fact that every other character around him (and the readers) know very well what they mean.
** This is somewhat justified at one point as it's pointed out that N[[superscript:o]]1 does this as a way of coping with stress.
** Subverted in book six: "I think we all know what [[PardonMyKlingon D'Arvit]] means."
** Artemis also has his moments: "My butler could kill you a hundred ways without the use of his weapons. Although I'm sure one would be quite sufficient."
* CharacterDevelopment: As the series progresses, Artemis develops from a ruthless criminal mastermind into something [[AntiHero almost heroic]]. A major part of ''The Time Paradox'' is contrasting Artemis pre- and post-development.
** Particularly obvious from the epilogue of the first book, which states That Artemis healing his mother was nothing but PragmaticVillainy to stop social services interfering in his schemes, that he would continue to exploit the fairies and be a thorn in their side for years after the Fowl Manor incident, and that Holly would become one of his greatest foes. Though the book itself says that the report is "94% factually accurate, 6% unavoidable extrapolation."
* CharacterNameAndTheNounPhrase: The new U.K. covers use this.
* ChekhovMIA: Artemis Fowl, Sr. The first book starts with Artemis Jr. actively looking for his father.
* ChekhovsGun: Several.
** Artemis' laser pointer is a literal example.
** The [[spoiler: seventh]] kraken in ''The Time Paradox''.
** The [[spoiler: toy monkey]]...
** The [[spoiler: finger gun]]
** And in ''The Last Guardian'', [[spoiler: the Opal clone could count as this or ChekhovsGunman - she is technically alive after all.]]
*** From the same book, we have [[spoiler: the eye that Artemis and Holly traded in Book Five. It ultimately leads to his ([[DisneyDeath temporary]]) death due to a special spell designed to kill any fairies within its bounds. While Artemis is mostly human, the eye is just enough fairy to [[HalfHumanHybrid qualify]] him.]]
* ChekhovsGunman:
** [[spoiler: Turnball Root, appeared in a short story and reappeared in the ''Atlantis Complex''.]]
** That sprite who told [[spoiler: Turnball]] how to re-acquire some magic? That's the first supernatural being who ever appeared on-screen: the fairy who loaned Artemis a copy of her Book way at the beginning of the series. Given that she hadn't appeared since the first chapter of the first book, and this was the ''seventh'', this probably is also a BrickJoke.
*** It's also to clean up FridgeLogic, because fairies are shown to lose their magic in certain situations, which this sprite may have been in, yet she retained enough magic power to heal some few human maladies.
** [[spoiler:In Book 4, Opal has herself cloned and leaves the clone in the Argon clinic during a jailbreak so no-one will suspect she has gone missing. In Book 8 she gets her hands on a magical superweapon which becomes magically encoded to only respond to her DNA... guess who Artemis enlists to disarm the weapon?]]
* TheChessmaster: Artemis (literally- one of his disguises as a chess prodigy ended up with a maneuver named after it), Opal Koboi. Spiro tries this, and is pwned.
* ChildrenAreInnocent It is stated that Artemis succeeds at finding the People because, being a kid, he is innocent enough to still believe in things like fairies and magic. His actions makes this innocence arguable at best.
* ChuckCunninghamSyndrome:
** Doodah Day. At the end of ''Lost Colony'', he is mentioned as having started working as a private detective along with Mulch Diggums. ''The Time Paradox'' takes place mostly in the past, so it's understandable that he wouldn't appear, but Mulch is actively involved in ''The Atlantis Complex'' and not only does he not seem to be working as a detective, there is absolutely ''no mention'' of what Doodah is doing.
** By the time of ''The Last Guardian'', [[spoiler:Mulch is apparently a wanted criminal once again with no mention of Doodah.]]
** Minerva Paradizo. At the end of book 5, she is stated to have spent 3 years obsessing over Artemis, waiting for him to return, and she was set up as a very obvious LoveInterest. Two books later, and she hasn't been mentioned once since then.
*** WordOfGod [[https://twitter.com/eoincolfer/status/3473367723 says]] she's dating a skier in the Alpes Maritime and has moved on past Artemis.
* CityOfWeirdos: It's mentioned several times that faeries often go to Disney Land on vacation, to no reaction from the human visitors.
* CleaningUpRomanticLooseEnds: A subtler case than most, considering these are childrens books, but in the The Last Guardian we've got Foaly and Callabine happily married and kicking arse, Trouble and [[spoiler: Lilli Frond]] hooking up and a [[spoiler: moment between Holly and Artemis at the end, but that could be more of a FriendshipMoment.]]
* {{Claustrophobia}}: Holly Short.
* CliffHanger:
** At the end of book 7, [[spoiler: Artemis ''still'' has the Atlantis Complex.]]
*** [[spoiler: Subverted, as Artemis is completely cured at the beginning of ''The Last Guardian''.]]
** At the end of ''The Time Paradox'', [[spoiler: Opal from the past is still on the loose in the present.]]
* ClipItsWings: Chix Verbil is hit in the wing with a softnose laser during the events of ''Arctic Incident''. Holly is able to save his life with some quick thinking and [[HealingHands faerie magic]], but since the blow ruptured several major arteries, she reckons that he'll never fly again.
* ColdFlames: Damon Kronski, leader of the Extinctionists, has a pit lined with flamethrowers which he uses to stage the execution of endangered species for the amusement of his supporters. Unbeknownst to him, another character (who wants the endangered animals saved for selfish reasons) fitted a trapdoor in the base of the pit and replaced the flamethrowers with hologram generators.
* ConcealingCanvas: Lampshaded by Mulch in the first book. Turns out to be a subversion, as the safe behind the painting is a decoy. Subverted again when the safe is in the painting itself.
* ContinuityNod: In the middle of a situation so ridiculous Artemis thinks it might be a delusion in ''The Last Guardian'', he shouts out "Four!" to check he isn't mad again.
* ConvenientlyPreciseTranslation: When Artemis uses a computer program to translate the fairy language into English, it comes out in rhyming couplets.
* CoolShades: they have a practical use in deflecting the fairy ''mesmer''.
* CorruptCorporateExecutive: Jon Spiro.
* CreepyChild: Artemis, especially in the first book. And the third, to the waitress. And again in the sixth.
--> "Who would want to kill Artemis? Every waitress and tailor on the continent, for a start."
* CriticalPsychoanalysisFailure: Artemis tends to have this effect on psychiatrists because he is much more intelligent than most psychiatrists and has read up on all the latest approaches to psychology. He can get them to diagnose him with whatever he wants. It helps that he's actually written some of the books his psychiatrists use to diagnose him.
%% the Crowning Moments (awesome, funny & heartwarming) have been moved to their own tabs. please don't add them back here.
* CulturalPosturing: Various fairy characters are fond of reminding Artemis how advanced fairy technology is compared to the "Mudman" equivalent. Unless it's technology that Artemis himself developed after meeting the fairies and reverse-engineering their gadgets. He even impressed Foaly by packing his 3D projection kit, which doubles as a user interface, into a briefcase.
* CulturalTranslation:
** The US edition of ''The Time Paradox'', has proudly Irish Artemis start referring to his mother as 'Mom' after making an emotional breakthrough. She gains the title 'Mum' in the UK edition, but even ''that'' may be a version of this trope, as she's referred to indirectly as the very Irish "Mam" in the first book.
** The second book, ''Artemis Fowl and The Arctic Incident'', had a line in which Artemis predicts he will be attracted to Holly when he reaches puberty that was removed from US editions. They needn't have bothered, [[spoiler: since he was right, and you couldn't have hidden it in TTP without rewriting half the book.]]
* CuteBruiser: Juliet Butler.
* CutLexLuthorACheck: Artemis is such a mega genius that he could easily make many millions of dollars as an inventor -- [[SubvertedTrope and, in fact, he does]]. ''The Arctic Incident'' says that he holds several patents and is designing a Dublin opera house. He does crime in order to make ''billions''. And, you know, [[GentlemanThief for the challenge]]. He also writes romance novels for pocket change - because he figured out the formula for writing the perfect romance novel, naturally.
* DaChief: Julius Root. [[spoiler:Then he gets gibbed. Ark Sool takes the position afterwards, but after he reveals his true nature, he's replaced by Trouble Kelp.]]
* DamselInDistress: Jayjay the lemur.
* DarkSkinnedRedhead: Holly, at least in the novels.
* DastardlyWhiplash: Mocked:
-->'''Butler:''' Focus, Artemis, one dastardly crime at the time.\\
'''Artemis Fowl:''' Dastardly, Butler? Dastardly? Honestly, we are not cartoon characters. I do not have a villainous laugh or an eyepatch.
* DeadGuyJunior: Sort of: [[spoiler: A curious case in Jayjay the lemur (short for "Julius junior") is indirectly named after Commander Root, who isn't dead the moment they choose the name, but is in the future that Artemis and Holly come from.]]
* DeadpanSnarker: so many. Artemis, Foaly, Holly, and Mulch (and occasionally Juliet) enjoy trading sarcastic statements. Mulch lampshades it in the narration of the fifth book:
--> Their little band of adventurers needed another smart-ass like they needed ten years of bad luck.
* DemonicPossession: [[spoiler:Opal]]'s possession of [[spoiler:Angeline Fowl]] seems to go beyond mere ''mesmer''.
** It's played even straighter in ''Last Guardian''.
* DevelopmentHell: (Apparently someone wants to make a movie with Jason Statham as Butler.)
* DiabolicalMastermind: Artemis sees himself as such, especially in book one.
* DidIMentionItsChristmas: Most of the first book takes place from Christmas Eve to before dawn on Christmas Day. This doesn't get mentioned until the ''last page'' (Not counting the epilogue).
* [[DieHardOnAnX Die Hard With Fairies]]: WordOfGod says so.
* DisproportionateRetribution: Implied in Book 1:
--> Juliet was the only person alive who laughed at him [Butler] with embarrassing regularity. Most other people did it once. Just once.
* DoctorsOrders: The CorruptCorporateExecutive's doctors are very much aware of his Mafia connections, so they give medical advice very politely.
* DoesThisRemindYouOfAnything?: The ending to The Eternity Code is suspiciously similar to that of DeadToRights, which came out a year earlier.
* DontTellMama: Artemis really doesn't want his mother to know what's going on, even if she suspects he takes after his father.
* DrivesLikeCrazy: Mulch Diggums:
-->'''Holly:''' What on earth were you doing, Mulch? The computer says you came all the way down here in first gear.\\
'''Mulch:''' There are gears?
** Mulch's driving technique is described earlier in the book as being "focus on the wheel and the pedals, and ignore everything else." He also assumed the shuttle had an automatic transmission.
** And in ''The Eternity Code,'' he scoffs at Juliet when she points out to him that he can't reach the brakes.
** And as of ''The Lost Colony'' Doodah Day:
--> '''Mulch:''' This close! We came ''this close'' to being incinerated. Give me your gun Holly, I'm going to shoot him.
* DumbassTeenageSon: In ''The Opal Deception'', Artemis plays this to a tee when out to steal a rare painting. He poses as the dim-witted, smart-mouthed, video game obsessed son of his bodyguard, Butler, as a successful distraction to the fact that's really a TeenGenius who's about to pull off the theft of a unique painting that is highly celebrated in the criminal underworld.
* EasterEgg: The "gnommish" coded messages running along the pages of some of the books and hidden in certain cover designs. They're a bit [[MindScrew weird]]. They claim you're a long-lost [[spoiler:fairy police officer]], for one...
* EatDirtCheap: The dwarves.
* EmbarrassingFirstName: In ''The Lost Colony'' [[spoiler: Abbot, the BigBad of the demons, was named after a character from a book taken from the human world, as were all demons when they come of age. His true demon name is N'zall, which means "little horn" in the demon language.]]
* EvenBadMenLoveTheirMamas: Artemis Fowl, multiple times, starting from asking [[spoiler: Holly to heal his mother in book one.]]
* EvenEvilHasStandards: Even at his worst, Artemis won't stand for [[GreenAesop mistreatment of the environment.]] He also won't kill people. Lemurs, maybe, but not people. When Holly compares Artemis to the villain Jon Spiro, Artemis uses this fact as his defense.
** In the first book, Cudgeon isn't pleased by his foul-mouthed subordinates.
* EveryoneOwnsAMac: [[TvTropesWikiDrinkingGame Take a drink]] for every Apple reference in the books. Good examples are Artemis's iBook, and the line in ''The Time Paradox'' about Foaly sucking information from the Apple Mac.
* EvilAlbino: Kronski seems to be this. He is described as having nearly transparent white skin and purple eyes. Since some forms of albinism manifest with purple eyes, and Eoin Colfer is not known for giving his humans odd eye colors, it suggests he may be albino.
* EvilGenius: One per book, two in book six. Artemis in book 1, Opal Koboi in book 2, Jon Spiro in book 3, Opal Koboi ''again'' in book 4, Minerva in book 5, Young Artemis and Opal Koboi ''AGAIN'' in book 6, [[spoiler:Turnball Root]] in book 7, Opal Koboi ''AGAIN AGAIN'' in book 8.
* EvilPoacher[=/=]EgomaniacHunter: The Extinctionists.
* EvilPlan: Each book really. The first one is staged by Artemis himself when he was a VillainProtagonist. "Capture a fairy and ransom them." Simple enough, right? Except he had to find one first, get their book, translate it, and then find a fairy that was worth ransoming.
* ExoticEntree: The Extinctionists from ''Artemis Fowl and the Time Paradox'' enjoy rendering endangered species extinct... and that, of course, includes dining on highly endangered or outright extinct species.
* ExpectingSomeoneTaller: Invoked in Book eight. A dwarf realises that he's only seconds away from being murdered by Opal, so he decides to [[DyingMomentOfAwesome go out with flair]] by making his last words an insult. "I always thought you'd be taller. Plus your hips are wobbly."
* ExtendedDisarming: Well, not ''disarming'', but near the start of Book 1, Artemis lists all of Butler's weapons hidden on his person.
-->'''Artemis:''' Let me fill you in on the weapons status. I am unarmed. But Butler here, my ... ah ... butler, has a Sig Sauer in his shoulder holster, two shrike throwing knives in his boots, a derringer two-shot up his sleeve, garrotte wire in his watch, and three stun grenades concealed in various pockets. Anything else, Butler?\\
'''Butler:''' The cosh, sir.\\
'''Artemis:''' Oh, yes. A good old ball-bearing cosh stuffed down his shirt.
:: He then goes on to say that Butler could kill someone in a hundred different ways ''without'' his weapons.
* EyeScream: The iris cam. Pure genius, but it ''sparks'' when changing the settings.
* TheFairFolk: "The People" Arrogant, and annoyed with the Mud People, yes.
* FairyCompanion: Played with: Artemis facetiously refers to Holly as "my fairy friend" at one point, but she is far too {{Badass}} to fit the trope.
* FakeMemories: Foaly explains that the mind will naturally create false memories to fill the gaps left by a mind-wipe
* {{Fartillery}}: Never stand directly behind a dwarf. Trust us on this one.
* FantasticRacism: The fairies are prejudiced against humans. This is presented as partly justified in the sense that, to some extent, HumansAreTheRealMonsters, but to some extent it's obviously a product of the fairies' recognisably [[{{Irony}} human]] limitations of perspective. The main reason cited is how unecological human actions are, but a favorite complaint is also [[ArsonMurderAndJaywalking how disgusting it's human toilets are indoors]]. The fairy races are also intolerant of each other, but with at least one being AlwaysChaoticEvil, it's not surprising.
** As of The Atlantis Complex, we see [[spoiler: Turnball Root]] commenting on how the fairies are wasting resources to the point of [[spoiler: throwing away something that would have only taken a dab of silicon gel to fix. The fact that it's also a mastercomputer of a space probe makes this an example of bad security as well]].
* {{Fanservice}}: Both graphic novels released so far have found an excuse to put Holly in a somewhat... [[ShowerOfAngst revealing]] [[VictoriasSecretCompartment light]]. The scenes in question ''were'' both in the original books, though.
* {{Fiction 500}}: He's '''#3''' on the 2011 list, behind only [[{{Literature/Twilight}} Carlisle Cullen]] and [[WesternAnimation/DuckTales Scrooge McDuck]].
* FindTheCure: ''The Time Paradox'': the only cure for Angeline Fowl's disease is the brain fluid of the silky sifaka lemur - The catch? Silky sifakas went extinct eight years ago. [[spoiler:Artemis himself made sure of that]].
* FingerInABarrel: A variation in the first book. Mulch is being attacked by a gang of goblins, and their ringleader summons a fireball and then inhales it up his nostrils, with the intention of breathing fire over Mulch. Mulch responds by jamming his thumbs up the goblin's nostrils; he gets his thumbs burned, but the goblin's innards take most of the damage.
* FireForgedFriends: Various characters find themselves growing closer through all their adventures and misadventures.
** Artemis and Holly are the prime example, seeing as how they've gradually gone from enemies to [[EnemyMine allies by necessity]] to somewhat-trusted companions to actual friends to closer friends.
** Artemis and Butler, at first, were just 'the closest thing' each had to a friend. By the end of book 2 and all that had happened, Artemis realized that he truly respected Butler. And by book 3, Artemis was willing to go through a great ordeal to save his life.
** ''Holly and Mulch'', of all people, became close enough for him to join her as her partner when she quit the LEP and became a private detective.
* FirstTimeFeeling:
** In ''The Time Paradox'', Holly [[spoiler:restores Damon Kronski's sense of smell in a particularly fowl smelling Souk, which reduces him to writhing on the floor, clawing at his nose]].
** Artemis realising for the first time during the Opal Deception that yes, he has friends.
* FiveManBand:
** TheLeader: Artemis Fowl is Type 1 "Mastermind".
** TheLancer: Holly Short; a heroic ActionGirl fairy is a perfect contrast to the AntiHero human ChessMaster.
** TheBigGuy: Butler; the big and scary BattleButler with a dozen weapons somewhere on his person.
*** Mulch may also count, only he takes obstacles out not with his muscles but with his... [[{{Gasshole}} uh]]... yeah.
** TheSmartGuy: Foaly; who singlehandedly invented all of LEP recon's technology.
** TheChick: Juliet, though also an ActionGirl she's girlier than Holly.
* FiveTokenBand: Turnball's gang is the Fairy equivalent: One elf, one sprite, one dwarf, one gnome, one goblin.
* ForgotAboutTheMindReader: Opal Koboi has her none-too-bright henchmen convinced to the point of paranoia that she can read minds, simply by turning on them at random and shrieking "I heard that!" One henchman tests her by thinking treasonous thoughts at her as loudly as possible.
--->'''Henchman (thinking):''' Holly Short is prettier than you.\\
'''Opal Koboi:''' Don't stare at me like that, it's bad for my skin.
* FourIsDeath: Invoked in the entire run of ''The Atlantis Complex''. Caused by the titular magical malady.
* {{Foreshadowing}}: In ''The Last Guardian'', [[spoiler: when Gobdaw [[AscendToAHigherPlaneOfExistence Ascended to a Higher Plane of Existence]], causing him to GoOutWithASmile, Artemis wonders if, when he dies, will he do the same. [[DisneyDeath And then...]]]]
* FriendlyEnemy: Artemis and Holly start off this way.
* FriendshipMoment: Many across the series from Holly and Artemis especially, but the ones that stand out are Artemis giving Holly the chance to [[spoiler: say goodbye to Commander Root]] and in the last book, [[spoiler: Artemis realizing that yes, he would go to the ends of the Earth (and below it) for Holly.]]
* FunWithAcronyms: "LEP recon", the Lower Elements Police reconnaissance unit.
* GadgeteerGenius: Foaly.
* GambitPileup:
** The first book starts simple enough, Fowl faction vs LEP recon in a hostage situation. Then Mulch has his own agenda, Cudgeon has his own agenda, Holly's agenda shifts away from Root's agenda, and then there's a '''troll'''.
** In ''The Time Paradox'', [[spoiler:Artemis versus Opal. One particular example: When he takes off in the Cessna, it looks as though they are all trying to make a break for it... but then Opal uses her thermal imager to see there is only one passenger. She guesses it is a decoy... but then notices Artemis is concealing the lemur's body heat under his shirt. ''That's what he wanted her to see.'']]
* GameplayAndStorySegregation: An odd example; the faerie language is apparently a language of symbols, but for all the codes at the bottom of the book, each symbol is translated directly to an English letter.
* {{Gasshole}}: Mulch Diggums, and the dwarves in general.
* GenderBlenderName: The title character (sort of; "Artemis" as a ''human'' name is genderless). He also claims to write romance novels under the name Violet Tsirblou in an inversion of MoustacheDePlume.
* GeniusBruiser: Butler may not quite equal his employer in heist-planning, but he's still pretty damn smart and outstrips him in several other fields.
* GenreBusting: An international espionage/science-fiction/crime thriller with a teen protagonist. And fairies.
* GentlemanThief: Artemis executes elaborate heists for the challenge and, after book one, seems to pick targets that he feels deserve it.
* GeorgeJetsonJobSecurity: At one point in the first book, Artemis' mother demands that he fire a maid that displeased her. Artemis agrees to, then offers to hire Butler's sister Juliet as a replacement, which is approved. Since Juliet ''was'' the maid in question (Something Mrs Fowl was not capable of realizing given her mental state for much of the book), this resulted in no actual change to the status quo.
* GettingCrapPastTheRadar:
%% "D'arvit" in general is not radar-busting, it's PardonMyKlingon.
** In the sixth book, while it did fit the language-obsessed character, a particular quote seemed to be directed as much at the readers as at the other characters:
---> "I think we all know what ''D'Arvit'' means," said N[[superscript:o]]l, "But ''hurkk'' is not English."
** Artemis totally just flipped off Abbot.
---> Artemis Fowl grinned right back at him and pointed his index finger at the sky. Actually, it was his middle finger, due to the time tunnel switch.
* GiantSquid: Artemis is attacked by one in ''The Atlantis Complex''
** I'm the nut![[labelnote:explanation]]Artemis is in a specially-armored deep-sea diving suit, tracking down a giant squid. Unfortunately, he underestimates the squid's intelligence when he realizes the squid is tracking ''him''. He sees the squid pick up a large chunk of a sunken ship in a tentacle and notes that it's like it's wielding a hammer or mallet of some sort. Artemis thinks to himself "Okay, it's got a hammer, what sort of nut does it need to crack?" Cue OhCrap reaction when Artemis realizes ''he's the nut''.[[/labelnote]]
* AGlassInTheHand: When Artemis enrages Gobdaw in ''Last Guardian'', Gobdaw responds by snapping a martini glass and trying to attack Artemis with the sharp end of the stem.
* GoOutWithASmile: [[spoiler: Julius Root.]]
* GreenAesop: The series teems with these, some more subtle than others. As of book five, environmental issues have not featured in the main plot, but the fairy people are quick to criticize humanity's lack of respect for nature and Artemis tends to agree with them in an EvenEvilHasStandards sort of way. Book six, ''The Time Paradox'', brings this front and center with the main plot focusing on an endangered lemur. Even the EasterEgg codes in some of the books are somewhat {{Anvilicious}}ly pro-green.
** Interestingly, in the first book, he nonchalantly destroys a whaling ship, [[XanatosGambit as a side-effect of some of his other schemes]]. Despite his apparent aversion to killing, he calls it a bonus.
--> There were less objectionable ways to get oil by-products, thought Artemis.
** The seventh book opens with Artemis unveiling his plan to end global warming.
** Comes to a head at the eighth book with [[spoiler:practically all modern technology being destroyed ('cause of Opal, by proxy) and green technologies replacing them.]]
* GreyAndGrayMorality: In the first book, an argument could easily be made for either side being the "good guys".
** In the case of Artemis himself, well... on one hand, he ''is'' an unashamedly greedy criminal (which his future self readily admits). On the other, he does have [[EvenEvilHasStandards some standards]], feels some guilt over his plan, and given the set of values that his father gave him, he certainly doesn't think he's doing the "wrong" thing so much as following a twisted sort of "God-helps-those-who-help-themselves" mentality. Plus, two of his less explicit reasons for his kidnapping plot were to heal his mother and raise more money to try and find his father.
** In the case of the LEP, some of them did some very questionable things, such as sending a troll into a house where it would be a danger to everyone, including the hostage. Many of them, including characters who were opposed to the troll idea, were later willing to kill several innocent bystanders (Fowl's mother and Juliet along with all of the wildlife) to take out Fowl and ensure that he wouldn't exploit the fairy world in the future. (Recovering the ransom was just a bonus.)
* GrudgingThankYou: Artemis to Holly at the end of book 2 and Butler to Holly in the first book.
* HealingHands: Any creature with magic can do it, though skill is a factor.
* HeelFaceTurn: Artemis, sort of. His father too, after he's recovered, thanks to Holly's meddling.
* HeroicWillpower
** Strong-minded individuals can put up some resistance to fairy ''mesmer''.
** This is also the main reason Artemis's atoms don't get randomly scattered through the time stream due to his multiple travels through it--"willpower," or at least intense focus and preservation of self, was stated to save him.
* HeterosexualLifePartners: Artemis and Butler.
* HeyYou: It marks a turning point in their relationship when Holly finally calls Artemis by his first name instead of "Fowl" (or "Mudboy"), and (much later) calling him "Arty". Likewise, when Artemis first calls his mother "Mum" instead of the more formal "Mother."
* HijackedByGanon: In ''Artemis Fowl and The Time Paradox'', the apparent villain-of-the-day (or yesterday) Damon Kronski turns out to be the pawn of [[spoiler:Opal Koboi]].
* HoldingHands: Artemis and Holly [[ShipTease do this]] in ''The Time Paradox''.
* HollywoodChameleon: Discussed. When Artemis learns that Foaly named his Cham-foil invention in honor of the chameleon's signature color-changing ability, he wonders whether or not Foaly is aware that chameleons choose their color based on mood rather than as a means of camouflage.
* HopeSpot: A ''crushing'' one near the end of ''The Last Guardian'', [[spoiler: when Artemis tries to escape the Berserker Gate before it activates and kills him. He manages to jump out of the crater and begins to pass through the magical barrier. Holly is holding his hand, pulling him through, and Artemis thinks that a new life is ahead of him as an ambassador between humans and the People. And then the Gate kicks in and Artemis is dragged back in the crater. Butler doesn't make it to pull him out. Of course, it was only a DisneyDeath, but still...]]
* HorseOfADifferentColor: Book eight mentions that fairies once used trolls as steeds in times of war. [[spoiler:Mulch figures out the secret and rides a troll into battle against the berserkers.]]
* HowCanSantaDeliverAllThoseToys: Stopping time.
* HumansAreTheRealMonsters: According to the fairies, [[GreenAesop mostly regarding our treatment of the environment]]. In practice, Artemis is merely AffablyEvil (if that). Though other human antagonists would definitely count. Jon Spiro in the third book and The Extinctionists in the sixth book. The Extinctionists, however [[spoiler:TheManBehindTheMan turns out to be a fairy plot.]] It dies down as the series eventually, [[AuthorOnBoard though reluctantly]], concedes that both humans ''and'' fairies can be pretty bastardy.
* HumansAreWarriors: During ''The Opal Deception'', a kidnapped Holly and Artemis are taken to an abandoned theme park. Artemis sees some mannequins in a gift-shop window that are dressed up as humans, in various warlike poses.
-->'''Artemis''': [[EvenEvilHasStandards Is that how you see us?]]
-->'''[[BigBad Opal]]''': Oh no, you're much worse than that, but the manufacturers [[ThinkOfTheChildren didn't want to scare the children.]]
* HypocriticalHumor: From ''The Time Paradox'':
-->'''Opal Koboi:''' ''(meditating)'' Peace be within me, tolerance all around me, forgiveness in my path. Now, Mervall, tell me where the filthy human is so that I may feed him his organs.
* IDidWhatIHadToDo: Artemis gains a few DarkerAndEdgier points when he {{manipulat|iveBastard}}es Holly [[spoiler:'s feelings for her dead mother to agree to cure his own]].
* IDontPayYouToThink: Opal Koboi's treatment of the Brill brothers in ''The Opal Deception'' basically amounts to this. At one point, she even tells them not to so much as think in her direction and almost manages to convince them that she's actually able to tell when they're doing so.
* IfICantHaveYou: Young Artemis to Artemis about Jayjay in ''The Time Paradox''.
* IHatePastMe: Comes to the forefront in ''The Time Paradox''.
* ILied: In ''The Opal Deception'', Opal Koboi regarding the explosive strapped to Julius Root supposedly having had a "sweet spot," which, if Holly had hit accurately, would have saved Root's life.
* IllKillYou: Loafers in '' Artemis Fowl and the Eternity Code'', after he finally has enough of Mulch's taunting:
--> '''Loafers:''' I'LL KILL YOU! YOU'LL BE MY NEXT TATTOO! YOU'LL BE MY NEXT TATTOO!
* ImmortalProcreationClause: Although not immortal, fairies can only have one child every twenty years; humanity's faster reproduction is actually the main reason it was able to more-or-less take the world from them.
* InsecurityCamera: [[spoiler:Help along Artemis to bust Spiro's ass.]]
* InsistentTerminology: Artemis would like everyone to remember that the silky sifaka is a ''lemur'', '''''not''''' a monkey.
* InsufferableGenius: Artemis, Foaly.
* InternalAffairs: Ark Sool.
* InterspeciesRomance:
** Artemis and Holly. Well. Sort of.
** In ''The Atlantis Complex'', [[spoiler:Turnball Root's love for Leonor is what motivates him]].
** Also, [[spoiler:Orion]], who has a thing for Holly, [[spoiler: and claims Artemis does as well.]]
* IntrinsicVow: [[HypnoticEyes Mesmer]], Butler ordered to kill Holly, the "body refuses to keep functioning" version.
* {{Invisibility}}: An ability of most faries, except demons, needed to maintain TheMasquerade.
* InvisibilityCloak: Foaly creates an invention called Cam Foil to make the wearer of it invisible. It's more technological than ''Literature/HarryPotter'' cloaks, which serves some problems, such as it shorts out in rain and is not invisible to a camera. Also, the circuitry can be easily crushed and the wearer appears as a slight haze, so is still noticeable.
* InvoluntaryCharityDonation: Happens to [[spoiler:Jon Spiro]], who gets 90% of his billions donated to Amnesty International. Artemis ''had'' intended to keep the lot for himself, but got hit by a [[CharacterDevelopment sudden attack of conscience]] and satisfied himself with a 10% "Finder's Fee".
* IronicEcho: In Book 1:
-->'''Holly:''' Stay back, human. You don't know what you're dealing with.
-->'''Artemis:''' I believe it's time to let our diminutive friends know exactly who they're dealing with.
** [[spoiler: [[BookEnds And then, once more, in the final scene of the series.]]]]
-->'''[[spoiler: Artemis]]''': Stay back. [[LaserGuidedAmnesia You don't know what you're dealing with.]]
* IronicEchoCut: From ''The Opal Deception'' - "No one could pretend to be in a coma for over a year. Surely not. A fairy would have to be totally obsessed. ... ... Chapter 1: Totally Obsessed"
* IsTheAnswerToThisQuestionYes: At one point in the first book, they're watching a tape and Root asks Foaly if he can zoom in on Artemis' face. Foaly responds, "Can a dwarf steal the web from under a spider?" Root replies "yes", and Foaly says that it was a rhetorical question.
* IWantThemAlive: Spiro and Opal.
* IWasNeverHere: [[spoiler:The CameraSpoofing as above.]]
* JediMindTrick: Fairy ''mesmer''. It even includes the classic 'wave of the hand'.
* JumpedAtTheCall: Artemis sought the call out and kidnapped it. Orion is a bit more traditional.
-->'''Orion:''' Artemis never paid attention during self-defense lessons. I, however, always knew this day would come.
* KarmicThief: At one point, Artemis Fowl chooses to focus his efforts solely on stealing from the wealthy and corrupt. However, he explicitly says he is not aiming to be JustLikeRobinHood
* KickThemWhileTheyAreDown: Turnball Root to Holly in Atlantis Complex.
* KilledOffForReal:
** [[spoiler:Commander Root. Although he gets a TimeTravel cameo in The Time Paradox.]]
** [[spoiler:Commander Raine Vinyaya also gets it in The Atlantis Complex. Clearly, this is not a good rank for the LEP.]]
* LadyOfWar: Holly Short.
* LaserGuidedAmnesia: Fairy technology can do this, but it's costly and labour-intensive. Used on a random Mafia goon and Artemis after ''The Eternity Code''.
* LastOfHisKind: Jayjay, the silky sifaka lemur. [[spoiler: Not for long, because Foaly is going to clone more.]]
* LegacyOfService: The Butlers have been serving the Fowls for so long that they were the ''origin'' of the word ''butler''. The earliest known interaction between the two was the Third Crusade.
* LeftTheBackgroundMusicOn: In TLC, where Minerva is being held captive, she thinks that the situation is as tense as possible, and there's even theme music playing. Then she realizes the music is actually the BigBad's cell phone ringing.
* {{Leprechaun}}: Actually [=LEPrecon=]: the Lower Elements Police reconnaissance unit. The stereotypical human view of Leprechauns is a source of significant embarrassment for the elves. And Recon are actually the source of that stereotype, if the multiple references to "the top hat and shillelagh days" in the first book are anything to go by.
* LetsYouAndHimFight: Time travel and a violation of NeverTheSelvesShallMeet result in Artemis facing off against Artemis - and, for the first time, facing Butler as an opponent.
* LiteralSurveillanceBug: The [=ARClights=], genetically engineered dragonflies carrying biotech cameras, created by Foaly.
* LonelyRichKid: Artemis Fowl, book one. He spends all his time watching computer terminals for news of his father and caring for his insane mother.
* LongerThanLifeSentence: [[KleptomaniacHero Mulch Diggums]] got a total of 300 years for his burglaries against "[[FantasticSlur Mudmen]]"; subverted as fairies live very long.
* LoopholeAbuse: In one of Holly's combat simulation exams, she beat an insurmountable number of enemies by shooting the projector. As they didn't have any rules against that, they had to let her pass.
** Also the way she passed her [=LEPrecon=] exam. Despite the exam being interrupted by his brother Turnball and Holly saving his life, Julius Root says Holly failed because she didn't follow his orders. Then Holly shoots him with her paintball gun, because Root said the one sure way to pass was shooting him before he could shoot her (which nobody had managed in a century).
* LuckyTranslation: Trouble Kelp is called Truba in official Russian translation. It does sound similar as far as translation goes, and even though its main meaning is "pipe", its second meaning is "a disastrous situation"
* LuxuryPrisonSuite: Turnball Root manages to get one of these, receiving each item as a reward for selling out his former comrades
* MadLibThrillerTitle: ''Every'' novel beginning with book two has one.
* MagicalComputer: The Cube. Literally. Will do anything for you. Starting with hacking military satellites (human or fairy), and everything between that and diagnosing any medical conditions you have.
* MagicalDatabase: In Foaly's case, this might be a literal description.
* MagicKnight: Demons in ''Artemis Fowl and The Lost Colony'' are divided into two castes: ordinary demons develop no magical power, but metamorphosise into monstrous forms when they come of age, while warlocks develop magical talent instead of muscle. [[spoiler:Demon warlord Leon Abbott managed to steal some magical power from a warlock when he interrupted a spellcasting ritual and caused a freak accident, and uses the stolen magic to secretly bewitch the rest of demonkind into serving him.]]
* {{Masquerade}}: Fairies are real!
* {{McGuffin}}: Jayjay, [[LastOfHisKind the world's last silky sifaka lemur]].
* MeaningfulName: Multiple characters.
* MegaCorp: Koboi Industries, [[spoiler:prior to Opal's incarceration]], had many legitimate enterprises that manufactured "everything from weapon parts to medical equipment" and even ran illegal front companies that sold obsolete fairy technology to humans. [[spoiler:This allows Opal to cripple both human and fairy technology when she murders her past self and causes the majority of Koboi technology to violently annihilate itself.]]
* MemoryGambit: ''The Eternity Code'' and ''The Opal Deception''.
* MercyLead: Kleptomaniac dwarf Mulch Diggums is recruited for so many LEP missions - despite his official criminal status - that he practically receives a salary in Mercy Leads.
* MilitaryMaverick: [=LEPrecon=] Captain Holly Short tends to ignore the order to stand down and wait for reinforcements. As such, Root keeps screaming.
* MindScrew: [[spoiler: ''The Atlantis Complex'', if you can't keep track of the number of times the narrative changes to a scene taking place a few hours earlier or later.]]
* MismatchedEyes: Artemis was born with blue eyes, and Holly was born with hazel eyes. Then a mishap in a time tunnel caused them to trade left eyes.
* MoustacheDePlume: [[InvertedTrope Inverted.]] Artemis says that he writes romance novels under the name Violet Tsirblou.
* [[VampireInvitation Must Be Invited]]: Any species capable of magic. Forcing your way in without an invitation is a good way to loose [[VomitIndiscretionShot the entire contents of your stomach]], and repeat offenses cause loss of spellcasting.
** This restriction is later lifted by No.1's special brand of demon magic, and was [[LoopholeAbuse more porous than a slice of Swiss Cheese]] even before it was lifted - on at least three separate occasions fairy troops gain access to buildings by [[ExactWords deliberately misinterpreting]] what the human occupants say. %% This would be the Italian Restaurant in the first book where the kid yells "Socorro!" and Holly is listening, Artemis goading Spiro into saying "You can bring all the fairy friends you want.", and Juliet asking the tour guide at Phonetix if she can bring her "invisible friend.", both from Eternity Code.
* MyopicArchitecture: Butler destroys an ancient stone doorway because it's much weaker than the modern armored door. Also Mulch Diggums gets through the floor of an otherwise secure area.
* MySpeciesDothProtestTooMuch: Nº1 is intellectual and gentle at heart, but all the other demons he grew up with were "hit first, question later" {{Blood Knight}}s overflowing with machismo. After years of trying to fit in, this (and some hypnotic prodding) lead him to leave the island. Turns out, though, that he's not like the rest because he's the first warlock to appear in ages, and warlocks just don't have the same bloodlust that most demons do.
* [[spoiler: NarratorAllAlong: Holly Short is revealed to be the narrator of the series at the end of ''The Last Guardian'':]]
--> [[spoiler: Holly: "It all began in Ho Chi Minh City one summer."]]
* NeverASelfMadeWoman: Juliet grows up wanting nothing more than to duplicate her brother's accomplishments as a bodyguard and live up to the family name. Book 3 has her coming to terms with this attitude. Unfortunately for Juliet fans, her refusal of the bodyguard profession and conscious attempt to [[TookALevelInBadass level in Badass]] means [[LeavingYouToFindMyself joining a lucha libre troupe in Mexico and disappearing for the next three books]]. This is subverted with Opal Koboi because even though her father was successful and she entered the technology field too, he never encouraged or helped her in any way and basically wanted her to stay in the kitchen. Also, her company eventually puts his company out of business.
** Averted with Holly. She's actually the first female LEP Recon officer, and this is a large part of book 1.
* NeverGoingBackToPrison: In the short story "[=LEPRecon=]", Turnball Root decides he would rather kill himself by swallowing a Tunnel Blue spider than let his brother Julius incarcerate him.
* NeverHurtAnInnocent
* NeverTheSelvesShallMeet: ''The Time Paradox''. Ideally they wouldn't have, if everything had gone according to plan....
* NewPowersAsThePlotDemands: Dwarves. Seriously, at least one new one per book, kinda like SilverAge {{Superman}}. Along the course of the series, we learn that they can: tunnel by eating through earth, [[{{Fartillery}} fire a devastating barrage of digested rocks/mud/whatever they just dug through]], propel themselves underwater and ignore the bends because of intestinal bacteria, have saliva that works as a healing balm, can cling to walls if dehydrated, have glow-in-the-dark spit, which can also solidify to trap enemies AND contains a sedative capable of knocking people out (how exactly is only explained as far as Mulch's comment that "You didn't fall asleep because I didn't do your head"), have prehensile beards/antennae (very handy lockpicks/emergency automatic surgical needles)....
** [[{{LampshadeHanging}} Lampshaded]]. "Even the dwarves don't know most of their abilities,"
** In ''The Last Guardian'', [[spoiler:the present day Opal is able to detect the existence of the past Opal existing simultaneously in her head.]]
%% NightmareFuel was moved to the YMMV tab. please don't add it back here.
* NinjaPirateZombieRobot: In Book 1, Artemis is a fairy-kidnapping GadgeteerGenius mastermind at the head of a criminal empire.
* NoCelebritiesWereHarmed: Jon Spiro seems a lot like a very jerky version of Creator/DonaldTrump. [[note]]Isn't ''Donald Trump'' a very jerky version of Donald Trump?[[/note]]
* NoEyeInMagic: The fairy 'Mesmer' ability, which - with direct eye-contact - allows the fairy to hypnotize and control a person. Reflective lenses such as shades will block it (and, on one memorable occasion, mirror-surfaced contact-lenses are used to covertly block a Mesmer), but it CAN be conveyed across video-link, albeit at a significant power-loss. (Strong-willed people can shrug off Mesmer if it's by video. With direct eye-contact, the best you can hope for is to resist violently enough to die rather than carry out the commands of your fairy master).
* NonActionGuy: Artemis is brains, not brawn, and frequently regrets his lack of physical fitness and coordination when he is forced to take an active role in things. Foaly is more successful in avoiding the action; his involvement rarely requires him to leave his computers.
* NonSequiturThud:
** When Artemis wakes up from being knocked out by [[spoiler: Butler]] in the sixth book.
-->'''Artemis''': Sell the Phonetix shares!
** Foaly in the seventh book. This was apparently an "unpleasant childhood memory", but unlike Artemis's exclamation there's no context given.
--->'''Foaly''': Not the stripy ones! They're just babies!
* NoteToSelf: The laser disc.
* NotMeThisTime: In "The Arctic Incident," Holly and Root assume it's Artemis behind the B'wa Kell golbin smugglings, but after they kidnap him to find out, it turns out not to be the case.
** During The Atlantis Complex, Foaly suspects Opal is behind the latest plot to destroy Haven. As it's an odd numbered book [[spoiler: it's [[TheBusCameBack Turnball Root]].]]
* ObiWanMoment: The last act of [[spoiler: Julius Root]] before Koboi blows a hole in his chest is to [[TearJerker smile at Holly and wish her well]].
* ObstacleExposition: Happens in every book, sometimes more than once. All that advanced fairy tech seems designed to create Mission: Impossible security system scenarios.
* OddlySmallOrganisation: Artemis' criminal empire pretty much consists entirely of himself and Butler. After his father's disappearance, Artemis apparently scaled back the family operations to only one's which he could oversee personally (almost entirely grand larceny and fraud), and heavily invests the profits from these (although he does make great use from his family's and Butler's vast network of contacts).
* OnlyElectricSheepAreCheap: The People's sim-...everything.
* OurCentaursAreDifferent: Well, the only one we see is a TechnoWizard and InsufferableGenius, and pretty much the only person who can understand his TechnoBabble is Artemis. It is mentioned, however, that most centaurs are like this: without magic, but very intelligent (though Foaly presumably still qualifies as genius).
* OurDwarvesAreAllTheSame: Averted. They have a digestive tunneling system, unhinging jaw, glowing spit, jet pack flatulence, suction cup skin, and more.
* OurElvesAreBetter: Some sort of weird halfway-house between the Tolkien elves and old elves.
* OurFairiesAreDifferent
* OurGoblinsAreDifferent: They are lizardfolk, they are the only ones who are able to use fireballs, and they are the stupidest sentient race on the planet.
* OurHeroIsDead: [[spoiler: Holly's "death" in ''The Lost Colony'' is a textbook example - although the fact that she isn't the ''title'' character might give less [[GenreSavvy jaded]] readers momentary pause]].
** [[spoiler: Artemis pulls this as part of his gambit in ''The Last Guardian''.]]
* OutGambitted: In the ''Opal Deception'', Artemis [[spoiler: does this to Opal in spectacular fashion]].
* OutrunTheFireball:
** In Book 1, Commander Root is nearly killed by Artemis with a remote bomb. Commander Root, being a fairy, has to use his training to recognize the symbols... numbers... getting smaller... [[OhCrap a countdown!]]
** In Book 4, ''The Opal Deception'', Holly, after seeing a bio-bomb detonate in Artemis's hotel room, has to try and stop another one from detonating and killing her, as Artemis got out safely. She covers it with her LEP helmet, but the helmet crashes away and she has to outrun the deadly blue light.
* OvershadowedByAwesome: Butler and Holly are both significantly above average intelligence. They just have the bad luck to live in the same world as [[InsufferableGenius Artemis and Foaly]].
* PardonMyKlingon: "''D'Arvit!''" Lampshaded in the first book.
--> There is no point in translating that, as we'd have to censor it.
* ParentalAbandonment: Artemis's father is missing, presumed dead, while his mother is crazy. They both get better.
* [[PetTheDog Pet The Endangered Lemur]]: Artemis has mellowed some since book 1.
* PhotoprotoneutronTorpedo: The fairies use neutrino charges to blow stuff up at one point.
* PlasmaCannon: Koboi labs and Police Plaza have automated plasma cannons with stun settings.
* PrehensileHair: Mulch Diggums's beard hair, which can also serve as handy custom lockpicks.
* PromptingNudge: Near the end of ''The Arctic Incident'', Butler gives Artemis a nudge to prompt him to thank Holly for saving his parents.
* PunnyName:
** All over the place, most notably in ''The Last Guardian'' with the pirate duo Salton Finnacre and J'Heez Nunyan and the Chinese Warrior [[UsefulNotes/BarackObama Yezwi Khan]].
** The dwarf engineer in ''The Last Guardian'' is named Kolin Ozkopy.
** Artemis himself is fond of using these as pseudonyms. He published some romance novels under the name Violet Tsirblou ("violets are blue...") and submitted articles to psychology journals under the names "C. Niall [=DeMencha=]" and "Sir E. Brum". Also, the way Artemis makes a point of mentioning when he used a pseudonym can be seen as LampshadeHanging.
* PutOnABus: Juliet joined a wrestling team, and Minerva wasn't even ''mentioned'' in Time Paradox.
* RaceLift: Holly Short and elves in general are described as brown-skinned and, except for the pointy ears, able to pass as short humans in the books, but the graphic novels give her skin as fair as Artemis's. More subtly, the Butler siblings are described as noticeably part-Asian in the books, Butler passing easily for Chinese at one point despite being blue-eyed and terrifyingly tall. It's not noticeable in the graphic novels at all, to the point Juliet looks like a palette swap of Angeline.
* RealAardFictionalCharacter: Mulch Diggums, finding the life of a (rich) law-abiding citizen in the human world to be unbearably boring, soon resorts to kleptomania, stealing Oscars from (fictional) Hollywood stars.
* RealMenWearPink: Butler is a Le Cordon Bleu chef and enjoys old romance movies (his favourite is "Some Like It Hot"; tell anyone and he'll hunt you down); Artemis writes poetry and classical music, enjoys opera, theatre, and has designed an opera house.
* RecycledINSPACE: WordOfGod describes the series as "Film/DieHard [-[[UrbanFantasy WITH FAIRIES]]-]!"
* ReedRichardsIsUseless: As part of the long-running environmentalism anvils the Fairies never provide (willingly or unwillingly) technology that would help prevent humanity from polluting.
* ReLex: The fairy language appears to be a ReLex of English with Irish influences.
* ReplacementFlatCharacter: Artemis becomes a more decent person as the books go on, so ''The Lost Colony'' adds Minerva Paradiso who's doing nearly the same thing as Artemis in the first book. The younger Artemis they meet while travelling back in time in ''The Time Paradox'' also counts.
* RetCon: A minor one involving the story of how Foaly met his wife Caballine. In ''The Lost Colony'', the two met because Caballine was a fan of one of Foaly's inventions. In ''The Last Guardian'', the two met because Caballine was mistaken for a bank robber by Foaly's software and was thrown in jail, with Foaly having to apologize in person.
* RetroactivePreparation: In ''The Time Paradox'' Artemis and Holly are locked in the trunk of a car and decide that later on they'll go back in time and ask Mulch Diggums to come rescue them. Soon after, Mulch breaks open the trunk. They try something similar later on in the book, but realize that it only works once.
* RewardedAsATraitorDeserves: Happnes to Mulch in Book one. He tries to sweet-talk some goblins by claiming to sympathise with them, only to find out that the only thing they hate more than a dwarf is a traitor to his own kind.
* RidiculouslyDifficultRoute: In ''The Arctic Incident'', Artemis and his friends are trying to find [[WalkIntoMordor a way inside Koboi Labs]]. The good news is, Mulch has a cousin who worked as a contractor during the labs' construction, and they discovered an underground fissure that leads straight to the labs' foundations. The bad news is, the fissure opens and shuts periodically as it expands and contracts with heat from the Earth's core, it will only be wide enough for their shuttle to navigate safely for three minutes at a time, and it's at it's widest for a few moments right before the next magma flare.
* RivalScienceTeams: Foaly and Opal.
* RoyalsWhoActuallyDoSomething: [[DumbBlonde Lili Frond]], descendant of the first king of the People, works in the LEP.
* RuleOfCool
* RunningGag
** In Book 7, bivouacs.
** In Book 6, people referring to the lemur as a monkey.
** Artemis's lack of physical fitness and his repeatedly broken promises that if he can just survive ''this'' scrape, he'll start hitting the gym.
* RunningOnAllFours: Goblins.
* SadisticChoice: The beginning of ''The Opal Deception'' Opal forces Holly to choose between saving Commander Root and Artemis, then [[HopeSpot compounds the sadism]] by offering her a false [[TakeAThirdOption third option]]. [[spoiler:To add even more insult to injury, Opal didn't give Holly enough time to save Artemis even if Holly ''had'' left immediately.]]
* ScienceIsWrong: Subverted. Human understanding of certain scientific concepts is wrong, but only because human observations are limited by the fact that magic is actively hidden from "Mudmen." The scientific method is still a-okay.
* ScientificallyUnderstandableSorcery: Artemis states that magic is just an energy that can control other energies.
* ScrewTheRulesIHaveMoney: "Illegal tends to be faster." - Butler, books 2 and 4.
* ScrewTheRulesImDoingWhatsRight: Holly Short gets in trouble because of this on quite a regular basis.
--> "Have you ever actually followed an order?"
* SherlockScan: Artemis can pull this off.
* [[ShinyNewAustralia Shiny New Barbados]]: What Opal promises her henchmen in ''The Opal Deception''.
* ShipTease: [[spoiler:Holly kissing Artemis in Book 6 and more.]]
** Artemis hugs Holly to activate a weight-sensitive panel to open a locked door.
** They have to undress down to underwear and then hold hands in order to [[spoiler:TimeTravel]]. N°1 makes a parting shot about pronouncing them "man and elf". Then, [[spoiler:when they arrive in the past, Artemis is aged and Holly rejuvenated to the point where their [[MayflyDecemberRomance age disparity]] disappears.]] For bonus points, thinking about this disturbs Holly. That almost crosses the line from ShipTease to UnresolvedSexualTension.
** For the non-Artolly shippers, Book 7 reveals that [[spoiler:Holly]] and [[spoiler:Trouble Kelp]] went on at least one date.
** Also in Book 7, [[spoiler:Orion]]. While he usually spends time pointing out how much he loves [[spoiler:Holly]], he also lets it slip early on that [[spoiler:Artemis]] also has similar feelings, but chooses to hide them.
** Book five covers the time period in which Artemis experiences puberty. Being Artemis, the enormous mass of new-found emotions and hormones is little more than an annoyance, but, also, being Artemis, he has no trouble mentioning this annoyance whenever he was distracted by a pretty face. This also just happened to be the book in which Minerva- essentially a slightly younger, DistaffCounterpart to Artemis Fowl- heavily features. Furthermore, he actually mentioned feeling attraction towards her, specifically. And yet, beyond these passing mentions, the matter comes up roughly twice: once when they get along incredibly well on the phone, which lasts about twenty seconds, since they are currently attempting to ruin each other's plans, and again towards the end at Minerva's side when she is revealed to have been thinking about Artemis in an admiring sense.
** The Last Guardian has [[spoiler: the scene where Artemis and Holly attempt to out maneuver each other to save them from performing a HeroicSacrifice . Quelle suprise, Artemis wins, but the scene wouldn't be out of place in a romantic drama with more ''traditional'' love interests.]]
*** [[spoiler: He kisses her goodbye, too. And when he comes back to life he and Holly are left in a field of [[MeadowRun roses. Ahem.]] ]]
* ShoutOut: See ShoutOut.ArtemisFowl.
* TheSlowPath: Inverted in ''The Lost Colony''. [[spoiler: They return three years after they left. No. 1 was worried it would have been more.]]
** PlayedForLaughs in ''The Last Guardian'', where [[spoiler:Foaly uses the power of a van whose communication system has his personality to set off a time-stop; what takes five seconds for him is five years for the van.]]
-->'''[[spoiler: Foaly's van]]''': I missed you so much, dude! Did we win?
-->'''Foaly''': Yes we did...dude.
* SmartPeoplePlayChess: One of Artemis' covers was a chess prodigy. The guard, also a chessmaster (not [[TheChessmaster that kind]]), didn't believe it, and challenged him to a game. Artemis [[CurbStompBattle beat him in six moves]].
* SmugSnake: Jon Spiro
* TheSmurfettePrinciple: [[DeconstructedTrope Deconstructed]] like whoa in the first book, when Holly point-blank asks Root if he's harder on her because she's a girl. He admits it, and then points out that she's the ''first'' female in Recon, and [[GirlsNeedRoleModels needs to set an example]]. It's also worth noting that the only other female up for the job Holly considers a 'bimbo'.
* SocialServicesDoesNotExist: An aversion is discussed - in the epilogue of the first book, the person profiling Artemis theorizes that the reason he wanted Holly to heal his mother was not due to filial affection, but because social services was about to figure out that his father was missing and his mother was not functional, and he needed a way to keep them from designating him a ward of the state and sending him to a foster home.
* SomebodySetUpUsTheBomb: [[spoiler: How they defeat Opal Koboi the second time.]]
* SpaceWhaleAesop: Save the Earth or you'll kill the fairies!
* SphereOfDestruction: Biobombs. They explode in a (usually) sphere of light and kills everything within range, although they can be contained by Time Stops, which have a pentagonal base.
* SpoilerOpening: If you know how to read Gnommish, the first ''page'' of ''The Last Guardian'' says [[spoiler: The Last Will and Testament of Artemis Fowl.]] This comes up in English in the third act.
* StableTimeLoop: More or less. ''The Time Paradox'' has so many piled on one another it'll make your head spin. Even just ''planning'' to do something when he got back to the future made it retroactive fact, allowing him to reap the benefits before actually doing so. Even more, Artemis's obsession with fairies in the first book [[spoiler: is the result of residual memories from his future self, in which he learned about fairies and his own involvement with them, after a MindWipe]].
** [[spoiler: Completely defied in ''The Last Guardian''.]]
* StagedShooting: During the rescue operation in book 2.
* StockholmSyndrome: Holly to Artemis in book one, even mentioned by name at one point.
* StrappedToAnOperatingTable: Not really. Artemis just wakes up on one. Occurs for real in ''The Time Paradox''.
* SuperCellReception: Artemis once received a text message in the Arctic. Sent from a laptop ''inside the Earth''. One could speculate that the fairies have set up underground Internet and cell phone service providers... but it was Artemis' own laptop, so it probably ran on a plain old human-run ISP. Then again, it was GadgeteerGenius Foaly at the keyboard, though Artemis himself notes that it should have been impossible for him to receive the message.
** The story adheres more to actual physics when, asked if they can send a reply, Artemis nonchalantly quips, "Certainly. Just give me six months, some specialized equipment and [[AmericanCustomaryMeasurements three miles]] of steel girder." Foaly ''himself'' mentions how hard it was to patch into the human networks.
** ''The Last Guardian'' mentions that all fairy communications halted because the human satellites they were piggybacking on fell from orbit. They probably just install devices to block signals of human origin and use the full capacity of the human tech to their own benefit. Artemis, being Artemis, would have found unblocking the device child's play.
* SwissBankAccount: Artemis Fowl has several, though probably not as many as when he was still (moderately) evil. A couple of villains (most notably in ''The Eternity Code'') also had Swiss Bank Accounts, ripe for Artemis to dig his fingers into.
* TakeThat: Colfer can be utterly ruthless in his description of civilian fairies in the first book.
** A particularly noteworthy example is Dr. J. Argon, a pastiche of celebrity doctors as well as psychologists in general. Colfer also makes a rather deliberate note in the first book that Argon is "a psychologist from ''below the United States''".
** A short one at politicans in general: "Cudgeon was doing what politicans did best: trying to duck responsibility."
* TechnoWizard: Foaly, and Artemis himself to a lesser extent.
* TechnologyMarchesOn: A fair amount of Fairy technology and equipment considered superior to the human variety at the start of the series by either the characters or the author have become decidedly less so as the years have gone by. Notable examples include wrist GPS, wafer-thin laptop computers and the iris-cam. Several Future Soldier Programs currently in development will almost certainly make the original LEP Recon jumpsuit the next casualty.
* TeenGenius: Artemis, of course. And Minerva, who managed to calculate when and where demons will show up on Earth, without having ever seen the fairy book.[[spoiler: Although she did have Queffor({{sharing a body}} with Abbot) to give her the calculations for it.]]
* TeenSuperspy: Artemis is one, albeit self-employed. No government agencies for him - Artemis has the style and the gadgets. Juliet is another, and even [[BavarianFireDrill joins a SWAT team]] in ''The Eternity Code''.
* TerribleArtist: Mulch's "helpful" diagrams in ''The Arctic Incident''.
* ThemeMusicPowerUp: It may be a series of novels, but Artemis occasionally invokes this trope in his head.
** In the first book, when he finally acquires his metric ton of gold from the People, he imagines that somewhere, the 1812 Overture is playing.
** In ''The Eternity Code'' when Artemis meets Spiro on the airfield, he thinks that some music would be perfect for this situation.
** And then in ''The Time Paradox'', when he needs to think some mental music to clear his head, he thinks to himself: ''Plotting music, I need plotting music.''
** More literally in ''The Time Paradox'' when composing a symphony in his head stops his atoms being scattered.
* ThemeNaming: Most of the fairies have nature and plant-themed names.
* ThisIsReality: In book seven Artemis Fowl gains a psychosis. Foaly's response is to invoke this trope.
* TimeyWimeyBall: Sometimes time travel forces a stable time loop but then at others allows paradoxes with no explanation for why given.
* TitleDrop:
** Book 2, ''The Arctic Incident'', is retroactively title-dropped in book 4.
--> "Holly studied her trigger finger. A faint scar circled its base where it had been severed during the Arctic incident."
** Dropped quite a few times in Book 6.
** ''The Atlantis Complex'' also repeatedly mentions, well, Atlantis Complex.
* TooCleverByHalf: Artemis.
* TranslatorMicrobes: Fairies are able to converse in all languages, including dolphin and dog. This is explained as being partly [[AWizardDidIt one of the benefits of fairy magic]], and partly because fairies were the first creatures to develop language, and all other languages are at least partly based on Gnommish as a result.
* TropeNamer: An in-universe example: we're told Butler's family is so highly regarded, the profession was named ''after'' them.
* TunnelKing: Mulch Diggums
* TurnInYourBadge: Root keeps threatening Holly with this, especially after being seen by a toddler.
* UltimateJobSecurity: Invoked by Foaly. He designed most of his tech so that if anyone but he tried to operate it, a hidden virus would "bring it crashing down around their pointy ears". Needless to say, he abuses this situation by talking down to and making cracks about his superiors, knowing full well that even suspending him would greatly handicap the whole organisation.
* UniversalDriversLicense:
** Fish smuggler Doodah Day can allegedly drive any vehicle, be it human, fairy or otherwise.
** Mulch has jacked several hundred kinds of vehicles and drove only with "The gas and the steering wheel". He even managed to outrun a pair of missiles in first gear.
* UnmanlySecret: Butler, Artemis Fowl's six-foot-plus OneManArmy and BattleButler, likes watching romantic comedies, though he will never admit this to anyone.
* UnreliableNarrator: Lampshaded. The first book is framed as part of a report by Argon. "Details are 94% accurate, 6% unavoidable extrapolation."
* UrbanFantasy: Elves, goblins, and faries using assault rifles and jetpacks.
* VancianMagic: Everyone with magic has a certain amount that they have available for use. When they run out, they have to go through an arduous ritual to replenish it. Also, the mesmer uses up decidedly less power than the other magics... [[NewRulesAsThePlotDemands unless you need to heal the villain's chronic lack of smell.]]
* VetinariJobSecurity: Invoked by Foaly; if anyone but him tries to use his computer, it crashes. He can still have his pay docked, though.
* VillainProtagonist: Artemis in book one, not so villainous later on.
* VillainousBreakdown:
** Spiro in Book 3, after Artemis not only escapes from him, but calls the SWAT team, steals the Cube, and basically screws Spiro over after he had everything he could ever want in his hands.
** [[spoiler: Kronski]] suffers a particularly spectacular one
** The entirety of ''The Last Guardian'' is one for [[spoiler: Opal]], not that she was particularly stable to begin with.
* VoiceWithAnInternetConnection: Foaly in his role as MissionControl.
* VolleyingInsults: Mulch and Foaly in particular enjoy trading gibes.
* WakingNonSequitur: Foaly gets one in ''The Atlantis Complex''.
* WallCrawl: One of the dwarves’ adaptation is the ability to absorb moisture through their pores, which enlarge when dehydrated. While this is useful if you are trapped in a cave in, Mulch makes use of their suction-cup pores to scale glass buildings.
* WeaksauceWeakness: Animal fat.
* WeWantOurJerkBack: In Book 7, the predominant sentiment of anyone dealing with [[spoiler: Orion]]. Played for every ounce of humor and pain it's worth.
* WhatHappenedToTheMouse: Minerva. At the end of book 5, she is stated to have spent the last 3 years obsessing over, and waiting for, Artemis. She hasn't been mentioned since.
* WingedHumanoid: played with - except for sprites, fairies' "wings" are actually jetpacks.
* [[WiseBeyondTheirYears Wise Beyond His Years]]: Artemis.
* WistfulAmnesia: Artemis post-mindwipe. [[spoiler:Then he shows his former self when he discovers contact lenses he made to cheat the mesmer.]] As of ''The Time Paradox'', [[spoiler: Artemis being interested in fairies in the first book is actually due to this.]]
* WitchSpecies: Many of the fairy races in are this.
* WithDueRespect: In ''The Atlantis Complex'', Holly tells Foaly that the guidelines which suggest that in her situation she should retreat to a safe distance and construct a bivouac are "with respect... a pile of troll weevils." Foaly, who helped to write those guidelines, asks if she actually knows what respect means.
* WorldOfNoGrandparents: Mostly. Artemis' grandfather gets a nod in The Atlantis Complex, it's mentioned in the first book that his maternal grandfather died when he was two, and Angelina thinks Artemis is her father-in-law at one point. But that's about it.
* WorldOfSnark: Is there anyone in this series who doesn't snark around, outside of [[DumbMuscle Pex and Chips]]?
* WritersCannotDoMath: In ''The Time Paradox'', Artemis and Holly are sent back eight years in time. But in ''The Last Guardian'', it is mentioned multiple times that [[spoiler:past!Opal has been removed from her timeline]] ''five'' years ago. It seems Eoin Colfer forgot to add the three 'skipped' years from ''The Lost Colony'' in ''TLC''.
* XanatosGambit: In the first book. After abducting Holly, Artemis notices she has a tracer on her wrist so he does some quick soldering and gluing to place a tin camera inside. If it works then great, but if it doesn't, its still off Holly and all he loses is an advantage he never expected to have in the first place.
* XanatosSpeedChess: Not only can Artemis come up with new plans on the fly, he can ''calculate their probability of success''.
-->'''Foaly''': "Do you realize he had less than a minute to come up with this plan [[spoiler:to save Butler's life]]? That's one smart Mud Boy."
* YearInsideHourOutside: During The Time Paradox Artemis and Holly spend about three days in the past, whilst for Foaly and No.1 it's ten seconds. This is played for laughs at the end of the book. Doubles as LeaningOnTheFourthWall as the reader leaves Foaly beginning to count to ten, sees the whole of Holly and Artemis's journey and "returns" when he says it was the longest ten seconds of his life.
* YouCalledMeXItMustBeSerious
** Bodyguard etiquette demands that Butler never reveals his first name to Artemis to keep their relationship professional. [[spoiler:He reveals it in book 3, after he's been shot and believes himself to be dying - it's 'Domovoi', a slavic word meaning 'guardian spirit'.]]
** If Holly calls Commander Root 'Julius', it means she's about to disobey an order or do something else that will annoy him.
** In ''The Opal Deception'', Mulch only refers to the Atlantean sea-elf Vishby by his real name once, when he's imploring him to flee a submarine moments before it gets crushed by immense water pressure. The rest of the time he uses the demeaning nickname 'Fishboy'.
* YouHaveOutlivedYourUsefulness: In book seven we have the text:
--> ''Turnball's smile never wavered, and he kept it bright by promising himself that he would dispose of this fool the second he was no longer of any use.''
* YourMom: Butler distracts some men in the first book by insulting some men and saying that their mothers must be so proud.
-->The stranger had crossed a sacred line. He had mentioned the men's mothers. Nothing could get him out of a beating now, not even the fact that he was obviously a simpleton. Albeit a simpleton with good vocabulary.
