* BurgerFool: This trope is taken to an absurd, NightmareFuel degree, to the point that it deters people from eating fast food and watching the show with a clear conscience. Pretty much every fast-food chain is portrayed as a disgusting, horrible place to eat or work, with the likes of Crazy Taco, Mac-meaties, Bloaties Pizza Hog, and Chicky Licks.

* TheCakeIsALie: In "Door to Door", Zim and Dib's class is selling Poop candy bars for a fundraiser, promised that the student who sells the most candy bars will win a mystery prize. Zim goes to ridiculous lengths to get it, eventually selling 1.2 million candy bars, only to find out that [[spoiler:there was no mystery prize, it was just made up to get the kids to sell more candy bars]].

Unfortunately, the show proved TooGoodToLast. While quite popular, especially outside of Nickelodeon's typical demographic, its ratings did not have far to slip before Nickelodeon deemed the show's hefty price tag not worth further expenditure. This alone would have provoked mass outcry, but Nickelodeon also declined to ''sell'' the show's copyright (and there ''were'' other networks interested in purchasing it), to the dismay of creators and fans alike. The InternetBackdraft was considerable, but sadly, largely unsuccessful, with one exception--Media Blasters getting the rights to sell [=DVDs=] of the show. (The Media Blasters [=DVDs=] have since gone out of print, and Amazon.com has released their own VanillaEdition collections of the show in an attempt to fill the void. Nickelodeon has also released a "best of" disc, ''Operation Doom''. [[NoExportForAll All of which were only released in North America.]])

** The Megadoomer is a take-off on the [[NeonGenesisEvangelion EVA robots]], the final battle in the ChristmasEpisode segues into a parody of ''EndOfEvangelion''.

With that said, sometimes even the craziest rumors do wind up with a grain of truth to them. In September of 2010, JhonenVasquez disclosed in a [[http://www.questionsleep.com/mindspill/?p=2024 blog post]] that Nickelodeon ''had'' been seriously considering a revival, as Zim's ratings on Nicktoons were scoring second only to ''AvatarTheLastAirbender''. Although the final report was that the idea had been shelved, a {{Facebook}} [[http://www.facebook.com/OperationHeadPigeons group]] called "Operation Head Pigeons" (after a Facebook mishap, now Operation Head Pigeons 2.0) took to aggressively petitioning Nickelodeon with pleas to bring back ''ZIM'', a direct response to the announcement that Nick had considered reviving the show. Perhaps in response, the ''Operation Doom'' best-of disc was greenlit. There are also around 27 episodes available on Netflix.

''Invader Zim'' was an AnimatedSeries by JhonenVasquez, which premiered in 2001 on {{Nickelodeon}}. Reruns are still being shown on the Nicktoons channel as of this writing.

Set TwentyMinutesIntoTheFuture, this dark, {{CyberPunk}}ish show starred Zim, an Irken Invader sent by the Almighty Tallest to take over Earth (read: [[ReassignedToAntarctica shipped off here because he screwed up on his last invasion attempt]]; they just want to get rid of him, but Zim doesn't know this).[[hottip:*:In fact, the Irkens ''aren't even sure there's a planet here''; it's just they just want Zim gone ''that badly''.]] He is ineptly aided in this "mission" by a defective robot assistant named GIR.

This "alien invasion" attracts elementary school student Dib, a self-styled paranormal investigator just itching to expose something strange and weird. And Zim seems just the alien to expose...

Early episodes followed a rigid formula: Zim would attempt to get rid of Dib and conquer the world, while Dib would attempt to expose Zim, only for both to discover that FailureIsTheOnlyOption. But later episodes used a {{Snapback}} to do all sorts of bizarre things unrelated to the plot, and some episodes involved only one of them facing an external threat.

The dark humor and interesting storylines attracted loads of people [[PeripheryDemographic outside the targeted age range]]. Part of the reason for this is the show's distinctive art and writing style. The art style is a variation of JhonenVasquez's [[JohnnyTheHomicidalManiac previous work]], simplified for animation. Though at first the show stuck to a formula, the efforts of Mr. Vasquez and head writer [[MysteryScienceTheater3000 TV's Frank Conniff]] developed into a much more idiosyncratic, [[WorldOfHam hammy]], and [[SatireParodyPastiche satirical]] style.

Unfortunately, the show proved TooGoodToLast. While quite popular, especially outside of Nickelodeon's typical demographic, its ratings did not have far to slip before Nickelodeon deemed the show's hefty price tag not worth further expenditure. This alone would have provoked mass outcry, but Nickelodeon also declined to ''sell'' the show's copyright (and there ''were'' other networks interested in purchasing it), to the dismay of creators and fans alike. The InternetBackdraft was considerable, but sadly, largely unsuccessful, with one exception--Media Blasters getting the rights to sell [=DVDs=] of the show. (The Media Blasters [=DVDs=] have since gone out of print, and Amazon.com has released their own VanillaEdition collections of the show in an attempt to fill the void. Nickelodeon has also released a "best of" disc, ''Operation Doom''.)

Despite its short run, the show had and still has an über-huge fanbase, some of whom even now cling to the hopes of a revival. While logic would tell you that the odds are against it, even as late as 2010 [[http://www.questionsleep.com/mindspill/?p=2024 Nickelodeon actually has considered the prospect]], and by his own account Jhonen Vasquez would be willing to return should such a thing happen (which it most likely will not, but it's nice to know). In the meantime, you'll find yourself with plenty of company should you go looking for fellow fans, but this can be a bit of a double-edged sword given the nature of rumor on the internet, leading to the spread of a lot of well-intentioned but often grossly inaccurate information, especially regarding the circumstances surrounding the show's untimely cancellation (in a semi-recent [[http://www.questionsleep.com/mindspill/?p=1208 blog post]], the creator himself has noted that even IMDB and Wikipedia contain errors). Be wary of what you read.

With that said, sometimes even the craziest rumors do wind up with a grain of truth to them. In September of 2010, JhonenVasquez disclosed in a [[http://www.questionsleep.com/mindspill/?p=2024 blog post]] that Nickelodeon ''had'' been seriously considering a revival, as Zim's ratings on Nicktoons were scoring second only to ''AvatarTheLastAirbender''.

Perhaps in response, the ''Operation Doom'' best-of disc was greenlit. There are also around 27 episodes available on Netflix.

[[Characters/InvaderZim This page has a character sheet.]]
----
!!This show provides examples of:
* AbuseIsOkayWhenItIsFemaleOnMale: The way Gaz treats her older brother, Dib is a non-romantic example. No wonder She's nicknamed "Dib's scary sister".
* AdultsAreUseless: And how. So are most of the other children, for that matter. And a lot of the aliens. Really pretty much every one and every thing in this show is useless.
* AerithAndBob: The Irkens must have some interesting naming conventions, as the individuals who are identified are Zim, Tak, Skoodge, Spleen, Tenn and... [[EverythingsBetterWithBob Bob]].
** Even human children have an odd mixture of names. Nick, Kevin and Mary coexist with the likes of Dib, Gaz and Moofy.
** The common pathron appears to be monosylabics, as every three-leter name is one (Dib, Tak, Zim, GIR, Gaz, and even concepts as Irk and PAK) and most of the other names are this too (Spleen, Keet, Tenn).
* AgentMulder: Dib and the Swollen Eyeball people.
* TheAhnold: The Ice Cream Truck driver in Episode 1.
* AIIsACrapshoot: Zim's computer, after admitting it doesn't have enough information about the FBI, just makes up a bunch of crap. Then again, it only did so because Zim ordered it to make some "educated guesses" when it didn't have any info to work with.
* AlienAmongUs: The premise.
* AliensAndMonsters: A good number of the characters.
* AliensAreBastards: The Irkens to conquer other species for [[ForTheEvulz no good reason]], and all seem to be pretty warped and sociopathic in their own way.
* AliensOfLondon: Tak has a British accent while none of the other Irkens do. [[LaResistance Lard Nar]] has one too, though we only have one other Vort to compare him to.
* AliensSpeakingEnglish, although the Irken language [[FridgeLogic had its own alphabet]].
** Maybe he has a [[TheHitchhikersGuideToTheGalaxy Babel Fish.]]
* AliensStealCable: How Zim does a portion of his 'research.'
* AllCrimesAreEqual: Seargent Slab, Mall Security.
* AllPartOfTheShow: The ''Mysterious Mysteries'' host experiences a CreatorBreakdown in the middle of the show. [[ThrowItIn It saves his show from being cancelled.]]
* AlmightyJanitor: Agent Darkbootie, a high-ranking member of the Swollen Eyeball, apparently has a day job as a janitor at NASA.
** Sizz-lor is a very high ranking Irken.... Fry cook.
* AlwaysChaoticEvil: It isn't explicitly stated or anything, but one could infer this about the Irkens.
* AmazinglyEmbarrassingParents: Zim's Robot Parents.
* AnimatedSeries
* {{Animesque}}: Not at first glance, however. According to [[TheLastAirbender Bryan Konietzko]] and Ian Graham, JhonenVasquez was a big fan of anime, which influenced the show a lot. Mostly through angles and speedlines.
* AntagonistInMourning: In the unproduced episode "Mopiness of Doom," Zim loses all motivation when Dib takes a TenMinuteRetirement to learn "real science".
* AppliedPhlebotinum
* ArbitrarySkepticism: Dib in "Lice". But hey, at least he admits he was wrong and apologizes.
* ArchEnemy: Dib to Zim and vice-versa.
* ArtEvolution: Subtly. Most prominent when Zim and the other Irkens are suddenly drawn with two fingers and a thumb, to set them apart from [[FourFingeredHands humans]].
* ArtificialHuman: In the DVD writer's interview Eric Trueheart said that had the show gone on for several years, Dib would have discovered (while on a quest to discover why his life was so horrible) he was one, created by Membrane.
* ArtisticLicenseAstronomy: All over the place in ''Planet Jackers''. Parodying the Twin Cities bit from ''{{Fargo}}'', one of the pilots points out a [[BinarySuns binary star system]], implying it's a rare sight. However the truth is that most stars in the galaxy, or at least the most visible ones, are part of a binary system.
* ArtisticLicenseBiology: In-universe, {{played for laughs}} and [[LampshadeHanging lampshaded]]. Dib's organ structure is laughably unrealistic: "Arm control nerve? In... my belly?"
** Given that Dib is NotQuiteHuman, it [[FridgeLogic might even be plausible]].
* AsteroidThicket: In "Battle of the Planets".
* AudioAdaptation: Seven of the unfinished episodes already had their voice tracks recorded, so they were released on the Special Features DVD.
* AuthorAppeal: Well, more like Creator Appeal, as Jhonen has a thing for saying the words "Doom" and "Dooky", makes references to piggies, and has a good number of morbidly obese jokes in some episodes.
* AwesomeButImpractical: The Megadoomer, a HumongousMecha with a stealth feature that makes the mech invisible, but ''not'' the pilot; it's also a massive power draw. Actually, just about anything Zim does.
** The Megadoomer was made with those two flaws ''intentionally'', as a "[[TakeThat screw you]]" from the Irken-enslaved builders.
** This trope is taken UpToEleven in the '[[ExactlyWhatItSaysOnTheTin Battle of the Planets]]' episode. (See the RuleOfCool entry below.)
* BabiesMakeEverythingBetter: Horribly averted in Plague of Babies.
* BadHumorTruck: "[[AC:You like ice cream. You like ice cream. You love it. You cannot resist ice cream. [[ResistanceIsFutile To resist is hopeless]]. [[SeriousBusiness Your existence is meaningless without ice cream.]]]]"
* BadNewsInAGoodWay: GIR does this all the time. (Yay!)
** Unintentionally, of course. GIR seems not to be able to tell the difference between good and bad news.
** There's also the Resisty member who tells Lard Nar how their engine core has been replaced with "a new horrible one!"
* BadVibrations: In "Megadoomer".
* BalefulPolymorph: What Chickenfoot [[TooDumbToLive thinks]] he is.
* BedlamHouse: "We think Dib's even crazier than normal today! Can we use one of our crazy cards to send him to the Crazy House for Boys?"
* BigNo: Zim and Dib each get their fair share, but the Soda Can Guy in "Battle of the Planets" takes the cake.
* BigRedButton: Parodied briefly in ''Tak: the Hideous New Girl''
-->'''Dib''': How did I [[LampshadeHanging ever miss]] ''that?!''
* BitchInSheepsClothing
* BitingTheHandHumor
* BlackAndGrayMorality: The Zim vs. Dib dynamic, on average.
* BlackComedy: Only JhonenVasquez could make the hostile alien takeover of our world so twistedly funny.
* BodyHorror: Dib and Zim slowly morphing into giant bologna sausages.
* BondVillainStupidity: Zim with Dib, especially of the WhyDontYaJustShootHim variety. It's particularly noticeable in "Dib's Wonderful Life of Doom," where he had Dib helpless in his base, and shot him... with a [[AbnormalAmmo muffin-firing gun]], and then just let him go.
** Possibly [[JustifiedTrope justified]] in-universe as, at that point, Zim's rivalry with Dib was pretty much the only thing keeping him on the invasion-scheming track...
* BootCampEpisode: In "Hobo 13", Zim is sent to the military training world 'Hobo 13' and told that if he survives he can have a big sack of battle tanks.
* BottleEpisode: "Zim Eats Waffles".
* BracesOfOrthodonticOverkill: Gretchen.
* BrickJoke: In "Career Day," Zim is told his ideal career is as a fast food slave, and the episode, like most others, suffers from NegativeContinuity and so the viewer thinks nothing much of it. Fast forward to "The Frycook What Came From All That Space," and we learn that an Irken Control Brain reprogrammed Zim's PAK to register him within the Irken Empire as a fast food slave on Foodcourtia.
** The joke started even earlier, in the first episode:
-->'''Tallest Purple''': Weren't you banished to Foodcourtia? Shouldn't you be... frying something?
* BridgeLogic: Subverted on Hobo 13.
* BuffySpeak: ''All the time.''
-->"All while gathering crucial information, assessing the planet's weaknesses, making it vulnerable to our big... space ship... gang!"\\
"Score one for the human race! Score ''nothing'' for the Zim... thingy... race."\\
"By the way, it's not called parent teacher night, it's called Zim doom parent... Zim doom Zimmy... doom... night."
** and so on...
* BurgerFool: This trope is taken to an absurd, NightmareFuel degree, to the point that it deters people from eating fast food and watching the show with a clear conscience. Pretty much every fast-food chain is portrayed as a disgusting, horrible place to eat or work, with the likes of Crazy Taco, Mac-meaties, Bloaties Pizza Hog, and Chicky Licks.
* ButForMeItWasTuesday: Zim's reaction to Tak telling him how he ruined her life could qualify as this trope:
--> "Yes, yes, so you blame me for your horrible life, blah, blah, big deal!"
* {{Butterfly Of Doom}}: When Zim starts sniping at Dib via a temporal displacement device, Dib starts accumulating more and more debilitating injuries, and is eventually driven to the point of death... After which he is revived and equipped with a [[GiantMecha bionic exoskeleton]] by Professor Membrane. All further attempts on Dib's past life result in upgrades to the exoskeleton.
** Its final form, if you're paying attention, is a Mad Cat Mk. 3 armed with weapons that all come straight from ''{{Battletech}}''[=/=]''{{Mechwarrior}}'' - Jhonen Vasquez's favorite games.
** And, of course, when Zim uses the last pig to send a message to his past self to never use the time machine, the pig replaces his brain.
* ButtMonkey: Dib, to the point where when he and Zim are piloting Mercury and Mars respectively in "Battle of the Planets", Dib is piloting the Butt of Mercury.
** Zim fares slightly better compared to Dib, but he's been kicked around several times as well. Be it due to his various horrible injuries, frequent failures, or being despised by his own species due to his own incompetence and violent nature.
* CardboardPrison: From the Christmas special.
-->'''Dib:''' Hey. (tastes the bars) these are made of real candy canes.
** Immediately lampshaded and subverted with this.
--->'''Zim:''' And this time throw him in the actually strong jingle jail.\\
'''Dib:''' Why didn't you throw me in the strong one in the first place?
** There was also an episode where Zim got abducted by aliens even dumber and more incompetent than he was... all their prisoners escaped in no time at all
* CassandraTruth: Normally targeted at Dib.
* CatchPhrase
** GIR: "I love this show." or "This is my favorite show." or just, "TACOS!"
** Professor Membrane: "My poor, insane son."
** Dib: "MY HEAD'S NOT BIG!"
** ZIM: "I AM ZIM!"
*** Also, [[http://www.youtube.com/watch?v=Mpn3P0qjw0A&feature=related "SILENCE!"]], "DOOM!" and [[http://www.youtube.com/watch?v=jmgcjRu1s-8 "LIES!"]]
** Dib: "You jerk."
** Police Chief: "GET HIM!"
* CavalierConsumption: Gir does this frequently.
* CharacterOverlap: In the ''JohnnyTheHomicidalManiac'' spinoff, titular character [[MoralityPet Squee]] is in Ms. Bitters's class (although she is never given a name here), and nearly gets abducted by the two idiotic aliens from the ''Zim'' episode "Abducted" a total of three times. The aliens first appeared in the original [[JohnnyTheHomicidalManiac JTHM]] comics.
* CheerfulChild: Keef. This being [[CrapsackWorld Invader Zim]] [[ItGotWorse it doesn't end]] [[HighOctaneNightmareFuel well for him.]] [[IGotBetter But he gets better.]]
* ChewingTheScenery: Professor Membrane is really fond of this. As is Dib. And GIR. And the Tallest. And pretty much the whole cast except Zim, who's [[LargeHam like this almost constantly]].
--> '''Professor Membrane''': "Not now, son! I'm making (electrical arcs flash from his workbench) ''TOAST''!"
* ChewToy: Poor little Invader Skoodge...
* ChildHater: Ms. Bitters, beyond a shadow of a doubt.
* ClarkKenting: Zim.
* CloudCuckoolander: GIR.
** To a lesser extent, Zim and Dib.
* CompulsorySchoolAge: Zim's older than any human alive, and in "[=NanoZim=]" he taunts Dib that he's been flying ships since before Dib was born, yet he attends what appears to be an elementary school -- and with his height, he fits in, although [[PaperThinDisguise he really shouldn't]]. He opted to do so, believing it to be the best way to retrieve information about the species he intends to conquer.
* ConspicuousCG: It doesn't blend in as well as, say, {{Futurama}}, but it still looks pretty good. The creators {{lampshade|hanging}} it in the DVD commentary for "A Room With a Moose", claiming that they spend the whole season's CG budget on the [[WhatDoYouMeanItsNotAwesome 3D walnuts]].
* ConspiracyTheorist: Dib and the Swollen Eyeball Network.
* ContinuityLockout: Played with in-universe in [[ChristmasEpisode "The Most Horrible X-Mas Ever"]]. Zim's motive for trying to conquer earth and where the Santa suit came from [[MemeticMutation COMPLEEEETLY ELUUUUDES]] one of the kids Mr. Slushy is telling the story to, because he didn't elaborate on it. His response is to[[CrowningMomentofFunny pick the kid up and tuck her 'under' the bed.]]
* ContinuityNod: Strangely, the use of the SnapBack did not serve as a deterrent to the use of this as well. In "Gaz, Taster of Pork" there's actually a ContinuityNod to an episode that ''was'' a SnapBack!
** Probably the best example of this is the way it's possible to trace the fate of planet Vort -- it's singled out for conquest in "The Nightmare Begins," seen briefly in "Walk for Your Lives" as the Tallest check up on the Invaders, is in the ''very next episode'' ("[=MegaDoomer=]") mentioned to have been conquered, in "Backseat Drivers" we learn it was turned into a prison, and in "Frycook" we hear about the faulty security systems that were initially put into place, presumably explaining how the Resisty's Vortian captain ([[AllThereInTheScript Lard Nar]]) is out and about.
* CoolAndUnusualPunishment: A lot of it, perhaps best exemplified by a room... ''With A Moose!''
** Banishment to the "Realm of Eternal Screaming and... Restlessness".
* CoolChair: Lard Nar, leader of the Resisty, has a chair that does not hover but has an extended attachment that lets it move around the ship.
* CosmicHorrorStory: The Halloween episode.
* [[CrapsackWorld Crapsack Universe]]: It is a show made by Jhonen Vasquez, after all.
* CreativeDifferences: In the behind-the-scenes show production, rather infamously.
* CreatorCameo: Various writers and animators were drawn into recurring background characters (including Frank Conniff, a.k.a. [[MysteryScienceTheater3000 TV's Frank]]). Series creator Jhonen Vasquez provided the voices of both Zim's computer and Minimoose.
* CreditsGag: Done in the episode FBI Warning, with the titular FBI warning in the beginning of ''Intestines of War''. Apparently, most FBI warnings are made by people threatened by smelly piggies.
** "The Federal Bureau of Investigation investigates allegations of criminal copyright infringement. They will hunt you down like the dirty monkey you are and force you to wear a moose skin and ride a greased piggy while singing folk tunes. They’re forcing me to ride the piggy as I write this. The piggy is smelly!"
* CrouchingMoronHiddenBadass: Zim is an idiot, but he is also a genius at times and shouldn't be underestimated.
** GIR also qualifies. While he's generally the ultimate CloudCuckooLander, he occasionally has moments of hypercompetence, if only by accident, and rarely screws up missions by himself.
* TheCuckooLanderWasRight: Dib spots right away that Zim is a dangerous alien. And [[YouHaveToBelieveMe nobody will listen.]]
* CutShort: Jhonen Vasquez already plotted out a finale right before the series was canceled.
* CyberneticsEatYourSoul: "Ten Minutes to Doom."
-->'''Dib''': Dad, do you know what this means? This device... it IS Zim. It's his brain and his life support. That means his body is just... something to carry his PAK around.
* DarkWorld: The Halloween episode features Dib flashing into an evil version of the normal world with monstrous versions of his already-weird home reality.
* DeerInTheHeadlights: Parodied in the "Ultra-Peepi" episode, where the masses aren't paralyzed in fear, but are too busy adoring his cuteness to get away.
* DepartmentOfRedundancyDepartment: The ShowWithinAShow "Mysterious Mysteries of Strange Mystery".
** Not to mention that a lot of Zim's lines tend to use this. ("Let us rain some doom upon the doomed heads of our doomed enemies.")
* DeusAngstMachina: It's a JhonenVasquez creation, this should go without saying.
** In "Walk of Doom", Zim walks into the tallest building to get to the top to get his bearings of the city. As it turns out, that building is a bank that was just robbed, and his human disguise looks just like the bank robber. Cue ChaseScene.
* DickDastardlyStopsToCheat: Zim'd be a lot more effective if he could just learn when to quit. In "Bad, Bad Rubber Piggy" Dib had lost just about all of his ability to represent a threat to Zim, but his continued attempts to KILL him after he'd already been crippled backfired rather spectacularly.
* DidMomJustHaveTeaWithCthulhu?: Gaz with the Shadow Hog, and Professor Membrane with Zim. Poor Dib.
* DisproportionateRetribution: Zim and Gaz in particular. In Zim's case, some examples (such as "The Wettening") overlap with ThereIsNoKillLikeOverkill.
** The episode "Dib's Wonderful Life of Doom" is practically made of this trope. Dib throws a muffin at Zim during lunchtime at Skool one day. What does Zim do to retaliate? He constructs a brilliant LotusEaterMachine for Dib based on everything the boy wants to do in life, and in Dib's twilight years, while being interviewed on a TV show celebrating his accomplishments, the TV host asks Dib if he'd been the one who threw the muffin at Zim all those years ago. Dib answers yes, and suddenly, Zim's face appears on the faces of everyone in the audience. Dib wakes up, in the real world, connected to a machine in Zim's lab. With this unpleasant little fact known, Zim coldly tells Dib to get out. Crushed, Dib begins walking away, only to have a gigantic gun aimed at his face. What fires out of the gun? A muffin.
* DoAndroidsDream: "... and why was my computer coughing?"
* TheDogIsAnAlien: Gir disguises himself as Zim's pet dog. ... his disguise being a bad costume with a zipper and a tongue sticking out.
* [[DoomyDoomsOfDoom Be Doomed by the Doomy Dooms of Your Doomly Doom, Doomed One!]]: This is, after all, the show that gave us the Doom Song, the Megadoomer, and even titles like "Mopiness of Doom" and "Dib's Wonderful Life of Doom".
** In the first episode alone there were no fewer than 36 "dooms."
*** "[[MemeticMutation I'm gonna sing the Doom Song now]]!"
**** Seriously, "Doom: TheSeries!" [[RunningGag might as well be an alternate title]].
* DoorToDoorEpisode: The episode titled... wait for it... "Door to Door."
* DoTheyKnowItsChristmasTime
* DrillSergeantNasty: In "Hobo 13".
* DumbassHasAPoint: In "Walk for Your Lives" Zim's plan to eliminate the explosion ([[WhatAnIdiot by setting it ''off'' on full speed!]]) is so terrible even '''''[[RalphWiggum GIR]]''''' realizes it.
-->'''GIR''': But won't it just explode? JUSTLIKETHIS, KABLAM!
** Fans seem to overlook the fact that GIR actually does this fairly often:
-->'''ZIM''': GIR! We've been seen out of our disguises! By a ''human!''\\
'''GIR''': But Dib's seen us. He knows where we live!
** In "Walk of Doom", when Zim and GIR get horribly lost in the big city:
-->'''GIR:''' Why don't we just ask the information humans for help?
* DyingLikeAnimals: Big time Bats.
* EarlyInstallmentWeirdness: In the original pilot, Dib is genuinely crazy, Zim isn't hammy (and is also voiced by BillyWest instead of RichardHorvitz), GIR is actually helpful, [[ArsonMurderAndJaywalking and Gaz's hair is purple instead of maroon.]] Each character also appears to have MoreTeethThanTheOsmondFamily.
* EasilyConqueredWorld: Which makes Zim's repeated failures all the funnier.
* ElaborateUndergroundBase: Zim's.
* EldritchAbomination: [[spoiler: Santa]]
* EmpathicEnvironment: "[=GameSlave=] 2": "The rightful order has been restored."
* TheEmpire: The Irken Empire.
* EnemyMine: "Bolognius Maximus" (which provides the page quote), "Halloween Spectacular of Spooky Doom", and "Tak: The Hideous New Girl".
* EnergyBeings: The Meekrob.
* EskimosArentReal: After Dib proves that "Chickenfoot" is a fraud.
-->'''Reporter 1:''' I bet this means [[BigfootSasquatchAndYeti Bigfoot]] is a fraud too!
-->'''Reporter 2:''' And [[FlyingSaucer UFOs.]]
-->'''Reporter 1:''' And [[TheLastOfTheseIsNotLikeTheOthers hobos.]]
-->'''Dib:''' No wait! Those are real! Except the hobos. Wait, no. They're real. I... I guess. But- [[SurroundedByIdiots what's wrong with you people!?!]]
* EverythingsBetterWithChickens: Chickenfoot, as well as other isolated gags.
* EverythingsBetterWithMonkeys: The Angry Monkey, Suckmonkey, "babbling like a maniac-monkey" "screaming like a howler monkey"...the list goes on. It should be noted that Jhonen Vasquez's original works often refer to monkeys ''a lot'' and this show is no exception.
* EvilIsPetty - Zim and Gaz.
* MessyPig
* EverythingsSquishierWithCephalopods
* WickedWeasel: "Computer! Take me to the ''WEASELS!"
* EverythingsWorseWithBees: Taken BeyondTheImpossible.
* EvilDuo: Zim (ego) and GIR (id).
* EvilLaugh: Zim, regardless of onlookers.
** Tak pretty much dethroned Zim with her laugh.
** Dib has a decent evil laugh.
* EvilTastesGood: "I can almost taste the humans being destroyed -- IT'SDELICIOUS!"
* EvilTeacher: Mrs. Bitters.
** Subverted with Mr.Elliot. He's so happy it makes you want to choke a kitten.
* EvilVersusEvil: Zim vs Tak.
* ExactlyWhatItSaysOnTheTin: the Doom Song; the "Halloween Spectacular of Spooky Doom"; "Parent Teacher Night"
** "Zim Eats Waffles," "Career Day."
** Many [[PlanetOfHats Planets of Hats]] have notably obvious names, such as Foodcourtia (a planet of almost nothing but restaurants) or Dirt (which Tak was assigned to clean).
* ExecutiveMeddling: Well, what do you expect when you have the [[JohnnyTheHomicidalManiac JTHM]] guy doing a show on {{Nickelodeon}}?
** Two specific incidents that make little sense, however: In the first episode, the writing staff changed radioactive rubber ants to rubber pants simply due to RuleOfFunny. In the words of Jhonen, "Suddenly we had a fight on our hands!" And in a later episode, they had to fight to keep a line in where a kid told his mom to have fun at work because Nickelodeon thought it was inappropriate to have that line. Why? Because it's about one in the morning, [[GettingCrapPastTheRadar leading some to conclude that the kid's mom was a prostitute.]]
* EyeScream: Walk of Doom. Zim looks directly into the sun... and causes his eyes to [[{{Squick}} burn and crust over]].
** There's also a brief moment in "Planet Jackers" where, after crashing his cruiser, Zim's eye ''pops out of its socket and into his hand'' for a couple of seconds. He quickly replaces it, but [[HighOctaneNightmareFuel still]].
** While it's cast in shadow, "Bestest Friends" ends with a Keef's eyes being ripped out by a machine and replaced with a pair of robotic duplicates that also control the brain.
*** [[BlatantLies It gets better!]] It's implied that while being attacked by a squirrel on the roof of the building next to Zim's house, Keef ''fell off'' and the impact '''''CAUSED HIS NEW EYES TO EXPLODE'''''.
* FailureIsTheOnlyOption: Zim will never conquer the Earth and Dib will never reveal Zim as an alien. More often than not, one's failure causes the other. Gaz herself [[GenreSavvy knows this]] and as such she never really gets involved in their rivalry willingly.
-->'''Dib''': Don't you care that Zim is trying to destroy all mankind? Huh?\\
'''Gaz''': But he's so bad at it.
* FauxAffablyEvil: Zim. The Tallests are arguably even moreso.
* FauxtasticVoyage: Inverted in "Room With a Moose".
* {{Flanderization}}: Keef is a particularly good example. What started out as a cheerful, somewhat lonely kid grew in later episodes (namely the unfinished Return Of Keef) to a full-fledged stalker.
* AFormYouAreComfortableWith: Spoofed; not only was the original form not that uncomfortable, but they turned into ''shoes''.
* FreezeFrameBonus: almost every headstone in the graveyard in Mortos der Soulstealer. Messages range from "JEFF: HE WAS NICE" to "LET ME OUT" and more.
** Bloody GIR, to an extent.
* FriendlyEnemy: Zim and Dib in the Pilot.
* FunnyBackgroundEvent: In Halloween Spectacular of Spooky Doom, three of the levels on the elevator are shown to be "Gym" "Pool" and "Tacos."
* {{Gainaxing}}: Zim's giant growing bubbly zit "Postulio" bounces in this fashion when Zim flicks it. FridgeBrilliance kicks in that this was HOW the zit hypnotizes people.
* GirlScoutsAreEvil: Moofy and the Girly Rangers.
* GrandfatherParadox: "In Bad, Bad Rubber Piggy." The resulting LogicBomb causes GIR to [[YourHeadAsplode literally explode]]. (That happens to him sometimes.)
* GrossoutShow: It had its moments. Mostly highlighted in "Dark Harvest", "Germs", and "Halloween Spectacular of Spooky Doom."
* HerrDoktor Countess [[TheVonTropeFamily von]] [[MeaningfulName Verminstrasser]].
* HeyItsThatVoice: Ken Nordina AKA "Movie Trailer Voice Guy" hosts the television show ''Mysterious Mysteries'', and gets the spotlight in one episode.
* HiddenBadass: Tak
* {{Homage}}: "FBI Warning of Doom".
* HomageShot: A scene from "Hamstergeddon" which the crew admits they lifted from the first episode of ''NeonGenesisEvangelion''. [[http://static.tvtropes.org/pmwiki/pub/images/zim_vs_eva_41.jpg Compare]].
* HotBlooded: Zim's computer; a strange mix of this (''Processing...'''PROCESSING!''''') and a StraightMan.
* HumanAliens: Subverted.
* HumanoidAliens: Almost all of them. The Meekrob, the Slaughtering Rat People, Shloonktapooxys of the Resisty -- and possibly the Plookesians -- are some of the only exceptions.
** Well, a lot of the background aliens look different, though a ''loose'' humanoid form does seem to be standard for "important" races.
* HumanOutsideAlienInside: Despite the fact that Zim appears to be able to pass for human with only a minimal disguise, his inner workings appear to be quite different. "Ow, my squeedlyspooch!"
-->'''Zim:''' "Don't come any closer! Don't try anything on me or I'll...I'll...I'll lay eggs in your stomach! I mean it!"
** Although that one may or may not have any basis in reality as he was primarily trying to scare off his "worshipers".
* HumansAreMorons: Every human is an idiot, except for Gaz and maybe Dib. Although it should be noted that the whole universe is portrayed as stupid much of the time, so they're really not any worse off.
* HumiliationConga: Everything Zim had set up for the humans in "Backseat Drivers from Beyond The Stars" blows up SPECTACULARLY.
* IGotBetter: Is a RunningGag for poor [[TheChewToy Skoodge...]] First he was sent to Blorch, home of the slaughtering rat people, for being the shortest Invader of Operation Impending Doom II. When he actually did conquer it, the Tallests still didn't like him and launched him out of a cannon. This still didn't stop him from making an appearance in "Hobo 13", where his remarkable recovery was {{Lampshade|Hanging}}d and {{handwave}}d:
-->'''Zim''': Skoodge? I thought the Tallests killed you!\\
'''Skoodge''': Yeah, but I'm okay now.
* IHaveAFamily: "I have children. And a toilet. [[BreadEggsBreadedEggs And toilet... children.]]"
* IKnowYoureInThereSomewhereFight:
** In "GIR Goes Crazy and Stuff", Zim tries to remind knowledge-mad duty-mode GIR of having been Zim's servant before.
** In "Dibship Rising", the Dibship, under Zim's mind control, is about to destroy Dib. Dib attempts to stop the ship by reminding it that it is essentially Dib too.
* IncessantMusicMadness: As Zim flies to Earth, [=GIR=] decides to sing the "Doom Song" on the way... ''for six months straight.'' Zim is just about to lose it when they finally arrive.
* IncomingHam: The first time we see Professor Membrane is when he is making... *sparks fly* '''[[WhatDoYouMeanItsNotAwesome TOAST!!!]]'''
** Of course, he is the inventor of "Super Toast!"
* IncrediblyObviousBug: Lampshaded, and so played for comedic value.
-->"Hey! Look at that garbage can!"\\
"Why yes, it ''is'' quite impressive, that can."
** Not to mention the time the 'tracking device' Zim uses on Dib is just GIR clinging to the back of his [[RunningGag 'enormous' head]].
* IneptAptitudeTest: "Career Day", in which only Dib gets the job he's so desperately trying for.
** Considering the circumstances surrounding Zim's banishment from Irk, his results were pretty appropriate too. He was banished to Foodcourtia after Operation Doom I.
* InformedAttribute: Used as a RunningGag brought on by ExecutiveMeddling (though the cast apparently enjoyed the joke) with Dib's freakishly large head, which is actually no different from any other characters' heads.
* InsignificantLittleBluePlanet: The Irken aren't even really sure if there ''is'' a planet in Earth's vicinity when they send Zim away. [[SnipeHunt Which was the whole point in sending him there...]]
* InstantAwesomeJustAddMecha: The Megadoomer, among others.
* InvisibleToNormals: Spoofed.
* IronicEcho: "You just don't get it, do you?"
* IronicEchoCut: In Halloween Spectacular of Spooky Doom, Zim is seen worrying whether GIR will be okay. Cut to GIR attacking trick-or-treaters and stealing their candy, [[CrowningMomentOfFunny flying tackling someone so hard their underpants fly off.]]
* ITasteDelicious: Dib, in "Bolognius Maximus".
--> "Gaz! Taste me! I'm delicious!"
* KickedUpstairs: Zim's task of ruling earth.
* KidnappedScientist: The Vortians are essentially an entire ''[[SlaveRace race]]'' of such.
* KidsAreCruel: But also stupid.
** Pretty much the entire reason for "Room With A Moose."
* KillItWithWater: Drives the plot of "The Wettening".
* KnightTemplar: The Delouser in "Lice," being rather [[{{anvilicious}} pointedly]] NotSoDifferent from Dib. Slab Rankle, the security guard from "FBI Warning of Doom," could be argued as one too.
* KonamiCode: It's a code for extra lives in one of Gaz's games.
* KryptoniteProofSuit: Zim's solution to being melted by water? A paste based coating.
* LotusEaterMachine: Is revealed to be the generator of most of the plot in [[spoiler:"Dib's Wonderful Life of Doom".]]
* MagicalDefibrillator: In "Bad, Bad Rubber Piggy." The paddles turn to pigs.
* MaximumFunChamber: Based on Dib's reaction, a room with a nut-eating moose is either this or a psychological BrownNote.
* MeaningfulName: GAZ and Zim are a make and model of Soviet-produced car, respectively.
* TheMerch: Still available at your local Hot Topic.
* MisappliedPhlebotinum: Spoofed to no end with Zim's inventions. Here's someone that builds a machine that can suck all the water off of the planet, but only uses it to win a water balloon fight.
* MostDefinitelyNotAVillain: Zim and the two aliens from "Abducted".
* MythArc: Or there would have been...
* NegativeContinuity: ''Attack of the Saucer Morons'' has not one, but two fairly-large groups of humans discover Zim's true identity. There's also the time Zim and Dib got turned into baloney apparently permanently.
** Zim never returns Earth to its proper place at the end of the planet stealers episode, plus the moon falls onto it
*** The same goes for the ending of "Hobo 13", where Zim is sent to the sun on a ship with locked controls by the Tallest. We never know how he managed to get out of that situation either.
** In more than one episode, some aired after "The Wettening", Zim is seen getting wet without causing him excruciating pain.
* NewMediaAreEvil: Inverted with Professor Membrane, who believes the reverse.
-->'''Prof. Membrane:''' Video games develop hand-eye coordination, and make children into better human beings.
** Possibly played straight with Gaz who has freaked out every character but Gir and Membrane
* NightmarishFactory: The skool's boiler room. [[AvertedTrope Surprisingly though,]] [[NoOSHACompliance it has plenty of guard rails.]]
* NinjaPirateZombieRobot: The "Ninja Ghost" Dib claimed to see in his toilet. The giant, flesh-eating, demon squid. The giant, flesh-eating, demon squid's cyborg demon minions. And so much more.
** When trying to come up with a name for their resistance movement, one of the suggestions for the Resisty's name was "The Pirate Monkeys."
*** Issa awesome name!
* NobodyCanDie: ExecutiveMeddling forced a number of changes in this department, although some deaths did manage to make it past the radar.
** The most humorous example of this is the mutated hamster episode, which ended with a still frame saying that nobody died. If you listen to the commentary of that episode Jhonen and the other cast members off-handidly mention "Oh, he's/she's dead" and ''completely ignore the still frame.''
* NoIndoorVoice: Zim. Who, for example, has a ''MIGHTY NEED'' to use the restroom.
* NoodleImplements: The final tier of Zim's test to see who is most fit to be his friend involves a toy taxi and a stuffed beaver. Whatever happened, it took half an hour and left the other participants other than Keef covered in third degree burns and barely conscious.
** The third degree burns were from Zim's second test of electrical conductivity.
* NoodleIncident: Several, especially concerning Dib's past:
-->'''Professor Membrane''': Son, there better not be any ''walking dead'' up there!\\
'''Dib:''' It's nothing to worry about, dad! And I said I was sorry about that!\\
\\
"Hey, you're Dib, aren't you? Tell me, did you ever get that [[NinjaPirateZombieRobot ninja ghost]] out of your toilet?"\\
"Yes, no thanks to you!"
** Then there was this little gem in "The Nightmare Begins":
--->'''The Letter M''': Yeah, what's wrong with you? All you talk about is aliens and ghosts and seeing bigfoot in your garage!\\
'''Dib''': He was using the belt sander...
** Don't forget whatever gave the Mysterious Mysteries host his scar. Honestly, it's probably safe to say that Dib's entire life is one big NoodleIncident.
** Zim's actions during Operation Impending Doom 1 would have been one of these if not for a ''very'' revealing {{flashback}}.
** Also, whatever changed the way Valentine's Day is celebrated.
--->'''Ms. Bitters''': I had a Valentine once.
** Then there's what ever it was that happened to the previous guidance counselor...
* NotMeThisTime: In "Planet Jackers", Zim initially thinks GIR is responsible for screwing up his telescope, but this turns out to not be the case.
-->'''Zim:''' Something is broken, and it's not your fault?\\
'''GIR:''' I know. I'm scared too!
* NoteToSelf: Seen in "Bad, Bad Rubber Piggy".
* TheNotSoHarmlessPunishment: "Gaz, Taster of Pork" ends with one. And, of course, the "Room With a Moose."
* ObliviousYoungerSibling: Sort of -- Gaz isn't oblivious, she just doesn't care. See above.
* OldMediaAreEvil: Zim despises television, which is constantly portrayed as garbage. Commercials in particular.
* OminousLatinChanting: Meats of Evil, "Bolognius Maximus".
* OneManArmy: Apparently skilled-enough and well-equipped Irken Invaders are capable of conquering the planet by themselves, though it seems it's mostly a case of leaving it up to their technology to do it once they enter the planet.
** Hell, a single functional SIR unit seemed pretty capable of conquering the planet, as shown during the episode where GIR gets (temporarily) repaired, and with Tak's functioning SIR unit.
* OneProductPlanet: Foodcourtia, the food court planet, Callnowia, the mail-order planet with Conveyor Belt Planet for shipping, Blorch, which is now the parking structure planet... the Irken love doing this.
* TheOnlyOneAllowedToDefeatYou: Drives the plot of both "Planet Jackers" and "Tak, the Hideous New Girl," as Zim won't tolerate an attempted takeover/destruction of Earth from anyone else.
-->'''Zim:''' The Earth is ''mine'' to devastate! And I already promised the moon to GIR.
* OnlyOneName: Dib and Gaz do not seem to have a last name (Zim's holographic Meekrob refer to Dib as "Dib... whatever-your-last-name-is"). A Nick.com e-card for the show claimed that Membrane's first name was [[EveryoneCallsHimBarkeep Professor]], but Jhonen (and the original flash version of official website) says that, in fact, Membrane is the professor's first name and his last name is a mystery like so many other things about him.
** Though this hasn't stopped fans from referring to Dib as "Dib Membrane," however, who seem to love using that as his last name. On occasion Jhonen himself has even referred to him (possibly mockingly) as "Dib Membrane" on his blog.
* OnlySaneMan: Dib. Even moreso Gaz, who's content in just letting Zim screw himself over.
** Gaz gets antsy if it involves video games...
** On the Irken side, Tallest Red.
* OrganAutonomy: Arm-control nerve.
--> "''Arm-''control nerve?"\\
[[OverlyLongGag "Arm control nerve."]]
* OrganTheft: "Dark Harvest".
* OutrunTheFireball: Or "Walk for Your Lives", as the case may be.
* OverlyLongGag: The Doom Song, again.
** The dodgeball fight in "Vindicated"
* [[PaintingTheFourthWall Eating The Fourth Wall]]: GIR eats the floating splitscreen for the snowman in "The Most Horrible X-mas Ever".
** In the original storyboards for "Backseat Drivers from Beyond the Stars" (which can be seen on the DVD), one of the scenes had Tallest Purple licking donut crumbs off your TV screen.
** Zim wishes you a Merry Christmas at the end of "The Most Horrible X-mas Ever."
* PalBonus: In "Game Slave 2", Iggins mentions that he already had the Japanese version but wanted the American version as it had a new level.
* PaperThinDisguise: Almost every single one.
** Zim's disguise consists of a wig and two contact lenses.
** GIR's dog disguise is green with a visible zipper.
** Zim's robot "parents" only bear a superficial resemblance to actual human beings, yet fool a roomful of people at Zim's parent-teacher conference. Even when "dad's" arm blows off in a shower of sparks, Zim is able to {{handwave}} it.
-->"My Dad lost his arm in, uh, the War."\\
"That was my squeezin' arm! They took my squeezin' arm! Why my squeezin' arm?"
** Then there were the literal paper-thin disguises of the aliens in the episode "Abducted". They were basically thin smocks with an image of a human body, and what appears to be papier-mâché masks. (This is made even funnier by the fact that they're supposed to be husband and wife, and [[TooDumbToLive they got the nametags mixed up.]])
** In "Planet Jackers" when Zim is looking through his telescope at the other Invaders, the only one we see is ''in'' disguise basically has a rock strapped to his head, making Zim's costume look brilliantly thorough in comparison. It is apparently sufficient to fool the natives, however, who are seen fanning him.
*** ''Tak'', at least, had a reasonable disguise though.
** Then there is Zim's secondary disguise from ''The Girl Who Cried Gnome'' and ''The Mose Horrible X-Mas Ever'' Which has his undisguised face peeking out through the mouth of the costume. Hilariously, at the end of ''Girl who Cried Gnome'' an artist's rendition of the "hero who saved the little girl" shows that they saw through the disguise, but still thought he was human as the depiction shows a normal human face peeking out of the costume's mouth.
* ParodySue: In "Dib's Wonderful Life Of Doom," when Dib gets superpowers [[spoiler:(or seems to)]].
* PeopleJars: Where little Irkens come from.
* PerverseSexualLust: A lot of it. It's that kind of fandom. The Irkens in general seem to get the most of it, perhaps because EvilIsSexy.
* PickOnSomeoneYourOwnSize: Interesting subversion here, as Zim and Dib ''are'' the same size, and Zim is from a culture that directly equates worth with height. The result is a rivalry that by all logic should be completely one-sided, as an alien older than any human on Earth, equipped with technology they could only begin to understand, finds an arch-nemesis in a grade-schooler.
* PlanetOfHats:: ...sort of. The planets that have been conquered are retrofitted to suit the Irkens' needs: Foodcourtia, the food court planet; the convention center planet; the shipping center planet; Hobo 13, the military training-planet; and so on...
** Played [[strike:straight]] straighter with some mentioned planets and dimensions such as: Exploding head planets, broken glass planets, a dimension of pure itching (you can't tell from the photo, but that stuff's really itchy), and a dimension of pure... [[ToiletHumour organic material]].
* PlugNPlayTechnology: Apparently, the Irkens use the same operating system that Dib uses. {{Lampshaded}}, and considering the way the line is delivered, it's likely a {{TakeThat}} at IndependenceDay.
* PolitenessJudo
-->'''Dib:''' The only way back home is through ''my'' head! Anything happens to me and you're stuck here forever!\\
'''Zim:''' [[BigNo NOOOOOOOO!]] CURSE YOU!...Wait. I can still do stuff to your legs, right?\\
'''Dib:''' I guess, but -- wait! No!\\
'''Zim:''' [[BigNo NOOOOOOOO!]] CURSE YOU!
* PsychopathicManchild: Zim, Chicken Foot, too many to count.
* TheRashomon: The episode "Mysterious Mysteries".
* ReallySevenHundredYearsOld: We're never actually told how old Ms. Bitters is, but WordOfGod is that she teaches at the school because they ''built it around her''. Zim is "[[http://www.revolutionsf.com/article.php?id=552&page=5 older than any human alive]]."
* ReassignedToAntarctica: How Zim came to Earth.
* RedOniBlueOni: Used most prominently in "Rise of the Zitboy." Zim is red and Dib is blue.
* ReedRichardsIsUseless: Professor Membrane parodies this. He's quite capable of creating such things as a Perpetual Energy Machine but will also on a whim decide that the populace is undeserving.
** He also averts it. The official website stated that he routinely creates miracle cures for all the ills of the world (according to ''Gaz, Taster of Pork'', he considers it incredibly horrifying that he still hasn't found a cure for "pigmouth" after ''one day'' of trying). With apparently no affect, since the world still sucks.
* ReligiousRussianRoulette: How guidance counselor Dwicky lost his faith in aliens.
* RememberTheNewGuy: Parodied. "That's Minimoose! He's been here all along, mm-hmm, yup!"
** Since the introduction episode was never shown, it was initially planned to show a montage of scenes from the series with Minimoose crudely pasted into them to go with the joke, but the idea was scrapped for time.
** In the very first episode, Zim tries to pull this off in-universe as a method of discrediting Dib's allegations:
--->'''Zim:''' Yeah, he's always saying stuff. I remember that one time--\\
'''Dib''' (incensed): YOU JUST GOT HERE!
* RentAZilla: Ultrapeepi.
* ResetButton: After catastrophically screwing up with a time machine that replaces objects in the past, Zim sends himself a note not to use the time machine. By replacing his past-brain with the note.
** Almost the same thing in "Dib's Wonderful Life of Doom," except it never happened to begin with.
* RidiculouslyCuteCritter: Peepi the hamster.
* RidiculouslyHumanRobot: Taken to BeyondTheImpossible levels with GIR. He is undisputably the most insane character in the entire series. "He" eats with ExtremeOmnivore tendencies, (in [[HalloweenEpisode Halloween Special]] of Spooky [[DoomyDoomsofDoom DOOM]] he attacked every trick-or-treater in the vicinity of Zim's house, apparently getting a sugar rush, then eating all their candy and becoming even fatter than the guy in the costume at [[SuckECheeses Bloaty's Pizza hog]].) drinks, sleeps, has a sense of smell (in one episode, for no discernible reason, he held a smelly dog in front of Zim and yelled "look what I found! He smells reeeeeealll bad!), cries, parties down and basically acts like a human child. "He" is also assembled from random bits of garbage, and is dangerously (and often explosively) defective.
* RiseOfZitboy: TropeNamer
* RobotBuddy: GIR, obviously, but the house computer to a lesser extent.
* RuleOfCool
-->'''Mars-oid''': My people worked themselves to extinction converting this planet into a navigable space vessel.\\
'''Zim''': Why would you do all that?\\
'''Mars-oid''': Because it's ''cool.''\\
'''GIR''': Mmm-hmmm.
* RunningGag: Dib's ([[InformedAttribute supposedly]]) big head, Membrane considering Dib insane, and spinal injuries.
** DVDCommentary RunningGag: Several.
*** "Hi, I'm Eric Trueheart, and I had ''nothing to do with this episode!''" (This one was repeated to the point where, when an episode he ''did'' write gets commentary, everyone else involved absolutely refuses to believe he wrote it. Richard Horvitz thinks Trueheart just transcribed it or something.)
*** "America ''loves'' GIR!"/"America hates Dib."
*** Pronouncing homage "oh-mah-g" in a drawn-out manner.
*** "How's it goin'?" said in the voice of Old Kid from the first episode.
*** "Did you color this, Rikki?"
*** Rikki Simons recollecting his consistent fear about being out of a job after each completion of the more... er, ''questionable'' episodes (such as "[[OrganTheft Dark Harvest]]").
** The mentioning of moose.
** Zim losing interest in whatever he's doing at the moment.
-->'''Dib''': You're going to use it to walk right past security at the generator, aren't you?! (Zim takes a few seconds to finish drinking his soda)\\
'''Zim''': Ah... What? Oh...(turns on the LargeHam) OH YES!
** While a lot is made about how terrible Zim's disguise is, if you pay attention you'll notice that ''all'' of the invaders we ever see in disguise are pretty terrible. Apparently tying rocks to your limbs or a prosthetic nose is all you need to get by as a covert agent. Tak alone seems to be the only invader to avert this.
* SadistShow
* SanityBall: GIR seems... different... in the episode Walk For Your Lives. He's a lot more focused than usual, and is quick to point out the obvious flaws in Zim's plans.
* SaveTheVillain: Dib agonizes over whether or not to save Zim in "Hamstergeddon" -- on the one hand, Zim's the only one who can stop Ultra Peepi, but on the other Zim will return to his attempts at world-demolition if Dib saves him. In a funny subversion, Zim recovers just fine on his own while Dib is agonizing over the decision.
* TheScream: Too many to count.
** The guy in "Battle of the Planets" might be the best.
-->"AHHHHHHHHH! AHHHH! AAHHHHH! NO! NO! AHHHHHHHHHHHHH! AHHHHHHHHHHHHHAAAAAAAAHHHHHHHH!"
* ScreamerTrailer: The host of [[ShowWithinAShow "Mysterious Mysteries of Strange Mystery"]] has these regarding Dib.
%% Screwed by the Network is under the Trivia tab
* SecretKeeper: Gaz is a subversion.
* SelectiveEnforcement: "Hey! That kid's throwing punch!"
* SelectiveObliviousness: It's obvious in the ''first episode'' how hated Zim is by the Tallest. Zim never notices.
* SeriousBusiness: Mall security, [[FrickinLaserBeams lasers]] (and Smoke Machines!), lice, ''video games'', parent-teacher-night, pizza... hell, is there an episode where this ''didn't'' feature?
** Not to mention the fact that apparently the library [[PoliceBrutality confiscates your retinas if something is overdue.]]
** Poop Cola Candy.
* ShadowDiscretionShot: A running gag in the series. Most notably with Keef getting his eyes ripped out, or in "Zim Eats Waffles" when he grabs something (slightly resembling a plunger) and blasts away the demon squid.
* ShapedLikeItself: Quite a bit, actually...
--> '''Zim:''' But...I ''must'' get my battle tank or I...[[CaptainObvious won't get it]]!
* ShouldntWeBeInSchoolRightNow: Fairly well averted, as very little seems to get past Mrs. Bitters. Zim or Dib (mostly Zim) will mysteriously go absent occasionally, usually to plot revenge, but all battles for world domination must take place after school, or under the guise of a bathroom break.
* ShoutOut: "So, Jhonen, was that your oh-mahg to..."
** Hall passes at the Skool take the form of an ExplosiveLeash.
** A lot of the music from the series has titles that are humorous {{Shout Out}}s. The best was the theme in "Walk for Your Lives" when the slow-moving explosion is let out on the city, which was called HappyFunBall. Another one from the same episode has the theme for when Zim is studying the explosion, with the title ''AnalyzeThis''.
** Zim wearing tissue boxes on his feet in the episode "Germs"
** The setting at the start of one episodes is not dissimilar to Edward Hopper's ''{{Nighthawks}}''.
** The conversation between the Planet Jacker pilot and co-pilot was a ShoutOut to a similar conversation in {{Fargo}}. Plus threats of cephalophagy.
** ''Hamstergeddon'' is an inversion of ''{{Gamera}}'', with the military unwilling to cause Peepi any harm at all and repeatedly brushing off Dib's pleas to terminate him with extreme prejudice. Ends with a subversion of ''Gamera'''s DeusExMachina ending.
** The Megadoomer is a take-off on the [[NeonGenesisEvangelion EVA robots]], the final battle in the ChristmasEpisode segues into a parody of ''EndOfEvangelion''.
** Tak's plan to hollow out the earth is a send-up of the 1966 ''Series/DoctorWho'' movie [[DaleksInvasionEarth2150AD Daleks' Invasion Earth 2150 A.D.]]
** The "My vision is impaired!" GIR shouts out in ''GIR goes crazy and stuff'' is also a reference to the Daleks.
** The cutting edge video game in Game Slave 2 is a clear homage to VampireHunterD.
** The Queen Louse in the episode Lice is a parody of the Alien Queen in the film [[{{Alien}} Alien]].
*** As is the scene in "Attack of the Saucer Morons" where Zim threatens to lay eggs in the human's stomach.
** Zim's original plan to destroy Dib in Bad, Bad Rubber Piggy is an obvious reference to {{Terminator}}.
** Dib's final form in Bad Bad Rubber Piggy? A Mad Cat from Mechwarrior.
** You can see [[SamAndMax Max's]] head on one of Zim's walls.
** Zim's birth (read: decanting) echoes ''BraveNewWorld''.
** The "[[BrainWashed brainwashing]]" of the robot parents in "Parent Teacher Night" is a blatant reference to "AClockworkOrange".
** The black robots floating about the auditorium in "Voting of the Doomed" look eerily like the Death Star torture droid from [[{{Star Wars}} Star Wars]].
* ShowWithinAShow: The Scary/Angry Monkey and Mysterious Mysteries of Strange Mystery.
** Probing The Membrane of Science With Professor Membrane!
* ShrugTake: "Zim Eats Waffles" ends with Dib about to freak out, but he can't get into it, breaks off with an irritated "{{whatever}}" and rolls into bed.
-->'''Sizz-Lor''': Wait, how can you remember what I said if you weren't even there?\\
'''Zim''': *shrug*
* SmartBall: Zim gets spiked in the face with one of these whenever Dib threatens to blow his cover, pulling off such stunts as nanoscale laser brain surgery, zit-based hypnosis and bulk organ theft.
** Dib also catches hold from time to time, repairing alien spacecraft and hacking into supercomputers.
* {{Snapback}}: Quite a few. Some could plausibly have an off-screen explanation, like "Planet Jackers," while others apparently stand in total defiance of canon ("Future Dib"). Likewise there are a few time skips that remain unacknowledged.
** "There was a time-warp or something." --Sizz-Lorr
* SpannerInTheWorks : A small chain of it. Zim is the spanner in the works to the Irken Empire, ruining Operation Impending Doom I, killing the Almighty Tallest, destroying part of the Irken fleet with Mars, and countless other failures such as forcing Tak to have to work as a janitorial drone. GIR is often the spanner in the works to Zim's plans, however idiotic they may be. And to top it all off, a spanner (or spanners) in the works for the Irkens (or a member of LaResistance, or just a slave really pissed at the Irkens) is sending machinery meant to help invaders to Zim, and malfunctioning machinery sent by the Tallest just to kill him to Invaders that are actually doing their job.
* SpaceTrucker: The Planet Jackers are quite reminiscent of long-haul truckers.
* SpiderLimbs: Zim's [[AwesomeBackpack PAK.]]
* SpoofAesop: The morals to Ms. Bitter's life stories. Usually extremely pessimistic and spirit crushing.
-->'''Ms. Bitters:''' The lesson is that dreams inevitably lead to hideous implosions.
* {{Stand-In Parents}}: Zim has robots to stand in as his parents, and despite them being horribly malfunctioning, nobody notices.
* StayWithTheAliens: Dwicky, the jerk.
* StealthPun: After GIR gets a ride home from a pig in "Germs," we hear the sound of a motorcycle engine. As in, [[DontExplainTheJoke hog... you know, Harley-Davidson...]]
* TheStinger: [[OnceAnEpisode In every episode]], a brief quote is played over the Nickelodeon logo following the credits.
* SuckECheeses: Bloaty's Pizza Hog.
* SuperiorSpecies: Provides the actual page quote. Although his mission is to blend in with Earth, Zim hilariously can't resist rubbing it in everyone's face how far more advanced and superior the Irkens are.
* TakeThat: In "GIR Goes Crazy and Stuff" and "Zim Eats Waffles", Zim is shown to have a human child captive in order to experiment with the happiness receptors in the child's brain. As a result, the child is compulsively happy. The child's name? Nick.
** In one episode Dib tries to take over an Irken computer, hoping out loud [[IndependenceDay that they just happen to use the same operating system as him]].
* TemporalParadox: Discussing them makes GIR's [[YourHeadAsplode head blow up]].
* TenMinuteRetirement: Dib in "Mopiness of Doom" (the unproduced script).
* TertiarySexualCharacteristics: Female Irken (there aren't that many of them) are distinguished by having fuller eyebrow/lashes and curly feelers. [[{{SelfFanservice}} Fandom typically chooses to ignore this.]]
* ThemeNaming: The main characters all have three letter names: Zim, GIR, Dib, Gaz.
** Red and Purple also count, though the other Tallests mentioned have different names.
* ThereIsNoKillLikeOverkill: The Wettening.
* ThirdPersonFlashback: Lampshaded. Zim remembers escaping from Frycourtia, and Sizz-Lor coming in and swearing to recapture him. Back in the present, Sizz-lor asks how he can remember that last part if he already left. Zim doesn't have an answer.
* ThirdPersonPerson: Zim does this a lot, especially when he's [[ChewingTheScenery hamming it up]] (and when is he not?).
* ThrowTheDogABone: After being the ButtMonkey his whole life, Dib gets the chance to salvage Tak's ship.
* ToiletHumor
* TooDumbToLive: The vast majority of the human race.
* TotallyRadical: Parodied by Poop Dawg in "Door to Door".
* TouchedByVorlons: Played straight [[spoiler: and later averted]] in Dib's Wonderful Life of Doom.
* TransformationSequence: GIR doing a WhatDoYouMeanItsNotAwesome version of putting on his dog costume.
* {{Transplant}}: Ms. Bitters and the Abductors were major characters in Jhonen's comic ''ComicBook/{{Squee}}'', though neither had names. Two Vortians also appear as rivals of the Abductors.
* TwentyMinutesIntoTheFuture
* TwoTeacherSchool
* UltraSuperDeathGoreFestChainsawer3000: Vampire Piggy Hunter, which actually looks to be a decent game.
* UndyingLoyalty: Zim is clearly loyal to the Irken cause.
* UsedFuture
* TheUsualAdversaries: Irkens for most of the galaxy. Zim for the Irkens.
* VillainEpisode: Inverted, given that Zim is a VillainProtagonist -- Dib occasionally gets episodes entirely dedicated to himself such as "Battle-Dib" and "The Sad, Sad Tale of Chickenfoot" where Zim does not appear at all.
** Also Gaz, in "Game Slave 2".
* VillainProtagonist: Zim.
* VillainsOutShopping: "Mortos Der Soulstealer", "Zim Eats Waffles".
* VomitDiscretionShot: "GIR! Your waffles have sickened me! FETCH ME THE BUCKET!"
** In the latin american dub, it was changed to "GIR! Your waffles have sickened me! [[BileFascination BRING ME MORE!]]"
** Sometimes, [[http://www.youtube.com/watch?v=aOUtjT2rwi0 this is averted.]]
* WackySoundEffect: Lots. There is a specific sound effect for stupid people straining their brains.
* TheWalrusWasPaul: Jhonen Vasquez decided to celebrate the "one month only" rerun of the show in March 2010 by giving an Invader Zim "fact" each day in his [[http://www.questionsleep.com/mindspill/ blog]]. All of them devolve into [[CrossesTheLineTwice very, very sick]] tall tales. Considering he rails against the misinformation about the show and its circumstances on the first post, it's not hard to interpret this as his attempt to outdo his own fanbase at bullshitting.
* WasOnceAMan
-->'''Rat person''': I was once a man!\\
'''Dib''': But you're a woman.
** Also Chickenfoot. [[TooDumbToLive Except not really]].
* WaveOfBabies: In "Plague of Babies".
* WeaksauceWeakness: Zim's ship crashes after a bee hits its windshield. The bee survived. Also, Zim's aforementioned issues with water.
* WeHaveReserves: "Hobo 13" is this trope over and over again.
* WhatCouldHaveBeen: Because of the complaints from Parents and Religious Groups, the series was killed off a Season Early. They had the whole final season planned and most of the scripts and Voice acting was completed. After the season True Series Finale Would have involved Dib Taking over Zim's Home Planet of Irk.
* WhatDoYouMeanItsNotAwesome: "I'm making...''toast!!''"
** "Jumping in a ''puddle''? ''That'' was your 'fate-of-the-world work'?"
** ''ZIM''... ''EATS''... '''WAFFLES'''
** [[http://www.youtube.com/watch?v=OAFkqZBubnU&feature=related Zim uses the bathroom]].
* WhereTheHellIsSpringfield
* WhiteVoidRoom: "A room... with a moose!"
* WombLevel: "Nanozim".
* WontTakeYesForAnAnswer:
-->'''Zim''': Is that Irken equipment you're using? That's Tak's ship you're sitting in, isn't it?\\
'''Dib''': Yes it is, Zim! It fell from the-\\
'''Zim''' ''(yelling)'': '''''Isn't it!?!'''''\\
'''Dib''' ''(also yelling)'': ''I said it was!'' Man, you have a problem with listening, Zim!\\
'''Zim''': '''''[++ISN'T IT!?!++]'''''
* WorldGoneMad
* '''[[WorldOfHam WORLD OF HAM]]'''
* WorldOfSnark
* YankTheDogsChain: "Dib's Wonderful Life of Doom" is ''all'' this, but "Vindicated" is probably worse.
* YouCanRunButYouCantHide: Dib says it to Zim, or rather ''tries'' to say it but just winds up contradicting himself. ("You can hide, but you can't.... hide!") In his defense he was seriously brain damaged by that point.
* YouDoNOTWantToKnow:
-->'''Dib:''' Miss Bitters? I read that long ago that people used to give out cards and candy on Valentine's Day. How did the whole meat thing get started?
-->'''Miss Bitters:''' [[NoodleIncident You don't want to know...]]
* YoungerThanHeLooks: The aptly-named "Old Kid".
* YourHeadAsplode: GIR does that sometimes.
* ZombieGait: A mall security guard sends a horde of zombies after Zim. He is initially scared, but soon realizes just how useless they are as they fall over each other and are completely incapable of harming him.
