  • The whole business with the Megadoomer usually flies over people's heads on the first viewing. Why, that thing couldn't be any stupider if the engineers who designed it had been deliberately trying to undermine it or something! Then those same engineers provide Zim with the Santa technology that runs amok in the Christmas episode, and intentionally give Zim the schematics for the Massive knowing it'll piss off the armada... are we seeing a pattern here? It's always, specifically, Vortian technology — and the Vortians, we learn, used to be Irken allies who were conquered and had their whole planet turned into one gigantic prison. Maybe the Irkens ought to be a bit more wary of technology provided by a race of people who have every reason to hate their guts.
    • This comes to an in-universe head in "Backseat Drivers From Beyond the Stars," when Zim secretly contacts an imprisoned Vort scientist for help on hacking into the Massive's computer...
      Prisoner 777: (sarcastically hammy tone) That would be wrong! It'd infuriate the armada! (suddenly helpful) I helped design that ship, you know. (beat) Here you go!
  • Some people have postulated that the bacon that was in the soap was made when Gir lit that piggy on fire.
  • Gaz is always seen squinting her eyes, save for when she's surprised or entranced. You may question why, but then you remember: Gaz is seen constantly playing video games. Studies have shown that staring at a digital screen for too long can cause sight problems. Gaz may in fact be squinting because of ruined, blurry eyesight from playing video games too much.
  • Miss Bitters has zero tolerance for Dib's rants about aliens and space. As shown in "Career Day", this could be because she was similar to him when she was a child.
  • In the episode "Bestest Friends", Keef mostly acts like a Stalker with a Crush. A crush... on Zim. And... wait for it... his shirt boasts a rainbow on it.
  • In "Parent Teacher Night", when accused of not knowing what parents are, Zim denies it while thinking of the "cold, unfeeling robot arm" that assembled him. Necessity might not be the only reason that Zim appointed two unfeeling robots to pose as his Earth parents.
    • Zim's complete lack of biological parents may also be the reason that he thinks all Earth babies come from space in "Plague of Babies".
    • Zim's affection for the robot arm seems like a quick gag at first, but it's also a sign that he's been defective since his birth. It's unlikely that a warrior race like the Irkens, who reproduce asexually, would be "programmed" to feel love at all.
  • In the DVD commentary, Eric Trueheart states that a possible future plot for Dib would have been eventually revealed him as an artificial human created by Membrane, which would make Gaz's attitude towards her brother make perfect sense. She disregards him entirely just as she would any of her father's other insane science projects, because that's exactly what Dib is.
    • In "Dark Harvest", Dib comments that he has vague memories of being abducted by aliens as a baby and having tests run on him, which he interpreted as them "trying to create a genius super baby". It's a long shot, but it's not completely out of the question that what he is actually remembering is his own father performing the final experiments needed to create him. His extremely young age at the time (as well as his tendency to see the paranormal in everything) would make it very easy for Dib misremember his own creation and mistakenly blame it on aliens.
  • GIR is shown eating something almost every episode. Where exactly does all that food go? He could be one of those biomass-eating robots.
    • Then again, it's probably just good old cartoon logic.
    • One possible explanation could be that all the food literally goes to his head. He then opens up his lid and dumps it out in the bin.
  • In "Career Day" Zim is assigned a future in Food Preparation after taking the assessment. At first it seems like a jab at the idea that instead of being lord of all humans, he's given one of the lowest, most demeaning jobs possible. However, we later learn in "Frycook" that Zim's PAK is still encoded for him to be a frycook. More than a coincidence?
    • It might also be because all his answers to the test were "human slave", not too inaccurate a description of a person earning minimum wage in fast food preparation. In other words, instead of making him ruler over humans, it made him a slave himself.
  • Zim has a surprising amount of Weaksauce Weaknesses to Earthen stuff; water, meat, beans, barbeque sauce, soda and juice all scorch his flesh like acid. It's been stated by Jhonen Vasquez that this is because of how polluted Earth is, but there's another reason that reveals itself over the series. In "Parent Teacher Night", it's revealed that Irkens reproduce by mass-cloning irken "smeets" in Uterine Replicators. And the tendency for repeat cloning resulting in genetic degradation is common enough to be its own trope. In "Bolognius Maximus", Zim notes his genetic structure is being overwritten by the bologna DNA much faster than Dib's human genes. In other words? Being a member of an all-clone species means Zim's genetically much weaker than a human, who has evolved amidst the increasingly polluted Earth.
    • Which brings up a brilliant idea as to why Earth's population seems to be so hideously deformed and stupid; negative mutations as a result of evolving to survive in their increasingly toxic environment.
  • Sergeant Slab Rankle goes to horrific lengths to protect his mall. But when you realize this is a world where homicidal aliens, giant mutant lice, and other nightmares run around unnoticed, some of that might be understandable.
  • A flashback in "Mysterious Mysteries" shows Dib as a baby, with a bandage on his head. This implies that he suffered some sort of head injury in his childhood, which might explain why so many characters find his head to be hideous In-Universe.
  • The planet-jackers are creating their own problem. They've thrown so much stuff into their sun that it's going to go out any time now, because a sun is not a bonfire and doesn't work like one. The only thing you'd want to put in a sun is hydrogen, and even that could cause problems for your planet.
    • It's possible the Planet Jackers don't just move their planet to a different sun because their ecosphere is in bad shape as it is. Towing the planet away from it's only heat source altogether would just make things worse.
  • Dib really does have a big head. It's a figure of speech used to describe someone who's full of themselves, which everyone probably sees Dib as being. Dib just misinterprets the insult to mean his head is physically big.
  • The Tallests seem to prefer Tak over Zim. Why is that? Well, if you look closely, she's slightly taller than him, and we all know how important height is to an Irken's dignity.
  • The trip from Conventia to Earth is shown to take six months, and the Irken transmission that departed at the same time as Zim is shown to reach Earth just before him for Dib to receive. Zim is stated to have been absent from Foodcourtia for twenty years according to Sizz-Lorr in "The Frycook What Came From All That Space". The Massive (with the Resisty's ship following close behind) is clearly shown flying through a sun in "Backseat Drivers from Beyond the Stars"; the closest star to Earth that isn't the Sun, Alpha Centauri, is four light-years away from the solar system. How can we reconcile all this information? Relativistic Time Dilation and Faster-Than-Light Travel.
    • To elaborate: At the beginning of the series, Zim's Voot Runner does not have an FTL drive. Earth is presumably twenty light-years away from Conventia. The Conventia transmission and Zim depart at the same time. The Conventia transmission is going at the speed of light, so it reaches Earth in twenty years, having experienced no subjective time between the origination of the transmission and its arrival. Zim is going at almost but not quite the speed of light, so he and Gir reach Earth in twenty years plus a little bit more, having experienced a subjective time of six months - enough to sing the entire Doom Song. The Massive, the Resisty ship, the Planet Jackers, Mars, etc. all have FTL drives, as does Tak's Spittle Runner. Presumably, Zim later upgrades his ship to have FTL. Considering that later during "Walk for Your Lives" the other Invaders are implied to be still in the process of conquest, it is possible that FTL drives compatible with Zim and other Invaders' ships were not in existence at the time Zim left Conventia, but had been invented by the time Zim got to Earth.
  • If you watch the episodes in order, "Walk of Doom" is followed directly by "Germs". The former episode includes a scene of Zim having a minor panic attack after observing the gross humans on public transport too closely. This moment probably made him react far more badly to the idea of Earthly diseases in "Germs" than he would have otherwise.
  • At first, Tak seems like a Parody Sue character, given how she's a lot more competent than Zim. Then you realize: we're comparing her to Zim, the Irken Empire's most legendary screw-up. Given what we saw in another episode–that the first Invader to conquer his designated planet was Skoodge–we can make the assumption that Tak wasn't created to be a Parody Sue; she was created to remind us how truly dangerous the Irken Empire can be when they aren't screwing around.
  • Apparently, the word Dookie means poop. Why did it replace that word? Poop is the name of a soda now.
  • When GIR takes over the school announcement in "Room With a Moose", he says that the kids would be sent on a field trip to a magical land made entirely of food. Given that there are dimensions of pure dookie and itchy, why not food? Unless GIR was referring to the dookie...
    • Knowing GIR, he could've been referring to the itchy dimension. What GIR considers "food" isn't necessarily actual food.
  • At the start of "Dib's Wonderful Life of Doom", Zim surrenders. It's extremely out of character for a Determinator like him. That's exactly why he chose it for his simulation. Zim has an enormous ego, and he can't accept the idea that Dib is better than him. He had to remove himself from Dib's life, because he can't accept that Dib could be powerful while he's around. Dib had to be somehow involved in putting Zim away; pretending to have caught an earth illness and died would arouse suspicion too early. So why does he go quietly instead of being defeated or arrested? There is always the possibility that his archenemy will defeat him, and Zim is afraid of that. Zim's not afraid of surrender because he knows he'll never give up, so pretending to give up is okay.
  • When the Meekrob appear before Dib, they initially look like aliens before inexplicably become shoes, when Dib points this out they aggressively insist that he always saw them as shoes. This was likely because of some glitch in the matrix replacing actual images of Meekrobs with tennis-shoes which Zim wasn't able to fix before Dib noticed.
  • When trying to figure out if Dib threw the muffin at him, Zim's simulation showed Tallest Red, at the point in time when he faked the Irken Armada invading, panicking and fleeing when the ship's snacks were blown into orbit, while Purple stood and watched him do so rather dryly and didn't react until the window was shot out. This seems rather uncharacteristic of them, since usually the dynamic would be switched. However, it makes sense to a certain degree. Zim, although wanting to make the simulation as believable as possible, wouldn't want Dib knowing too much about the actual Armada for when they came, just in case. It's likely that the personalities of the Tallest, and other aspects of the invasion, were altered just so that Zim could hide from Dib just what the Armada's weaknesses actually were so that he wouldn't get any ideas for stopping them later down the line.
  • When Tak is in her human form, she's mostly flawless in her appearance except for one factor: Unlike most humans in the show that have four fingers, she only has three.
  • When Zim makes his escape from Foodcourtia, he learns too late that Snacky Cabs are rigged to explode for "no apparent reason" if not docked. Considering Zim was a former prisoner there, it's possible this is another security measure to ensure the Foodening can't be used as a means to escape.

    Fridge Horror 
  • "Ten Minutes to Doom" gives us a revelation that only gets more horrific the more you think about it. The Irkens are nothing more than walking meat shells for the real technological brain that's contained in their paks, and their biological processes are so utterly dependent on it that they die if separated from the pak for as much as ten minutes. That couldn't have happened in nature. It would have to be something another sentient race did to them... or they did to themselves. Talk about Body Horror.
    • What's more, Irken smeets go through gestation and birth before being paired with a PAK. Dib's mind was being taken over when Zim's PAK attached to him. What is an Irken's body before it is given a PAK? Is it a mindless husk, or a creature with its own mind that the PAK overrides and destroys to replace with the PAK's mind?
    • Can't be. In the episode about parent-teacher conferences, Zim has a flashback about who his parents are. There are no parents, but it shows the pack being fused to his back. And he was perfectly healthy and happy without it. (I think that's the episode.)
      • Actually, no—Baby Zim is pulled out of a tube (yeah, apparently all Irkens are cloned) and he falls lifeless on a table, only moving and actually living when the PAK is attached to him and he receives an electric shock. Yikes...
    • This would mean Zim and all other Irkens are nothing more than robotic personalities stored in the PAKs that have been given a semi-organic body to control.
    • Even more horrifying when you consider the true masters of the Irken Empire: the Control Brains. As shown in "The Frycook What Came All The Way From Space" and "Tak: The Hideous New Girl", they make leadership decisions like reprogramming, judging, etc. And what do they look like? Giant PAKs.
      • The Tallest even submit to them, making them more like figureheads, not real leaders.
    • But, then how does the "pig in the head" thing in the time-travel episode (where Zim is replacing Dib's organs with pigs) even affect him? Isn't his brain in his PAK?
      • Perhaps the instructions from the PAK go directly to the brain and then to the rest of the body. Without the brain, the subject is "disconnected" until the object is removed (let´s say: by the base computer) and the organic brain regenerated (Irkens are shown to be able to regenerate multiple times during the show). If anything it could explain how Zim got out of that one.
  • "Bestest Friend" has a scene where Zim conducts some weird experiments on three kids to find out which one of them is worthy of being his friend. Considering he tested how well they conducted electricity by shocking them, just what was Zim doing to the kids using that beaver and toy taxi cab?
    • Word of God said Jhonen originally wanted blood to splatter on the wall during that scene.
  • In the episode "Plague of Babies", it is shown that the aliens - who look just like human babies - had called their ship for help, asking to be teleported back. But wait, the ship has the wrong coordinates and pulls a room full of actual human babies to outer-space instead. WHAT HAPPENED TO THOSE BABIES?!
  • In the unfinished episode "Return of Keef" Zim throws some sort of goo on Dib that makes anyone who is happy explode; why would Zim specifically make something that would cause happy people to explode? It's just silly; then, you remember that Zim had a human test subject, Nick, that is always happy because of a happy probe in his brain. Zim probably killed Nick.
    • Speaking of Nick, in "Zim Eats Waffles", Zim refers to Nick as "Neural Experiment #231". So uh, what happened to the 230 other neural experiments? If they were living things...then...yuck.
  • "GIR Goes Crazy and Stuff"
    • When the human with a squid brain (or squid with a human body) returns to the sea, the audience directly realizes 'Oh god, he can't breathe underwater'. Quite a fridge horror on its own, but then GIR happily comments: 'He's gonna get eaten by a shark'.
      • Watch that scene again. Gir states "He's getting eaten by a shark." As in, with Gir's X-ray vision, he is watching the poor man getting eaten. Alive.
      • In the cop's I Have a Family outburst, he mentions having children and pets and a toilet, but no wife. Did Zim orphan this guy's kids?
      • And if he did... well, that dog in the guy's photos looks pretty damned dangerous. Two small children are alone with a dangerous dog that needs to wear a muzzle...
      • Maybe the toilet was the mother?
      • Well, now they're alone...
    • What about the library scene partway through the episode? The guy who gets his RETINAS REMOVED because he had two overdue discs. Does he get them back for returning the discs? How does a library get sanctioned for taking the eyes of patrons with late discs? Who else met such a fate?
      • Better yet, how can he get them back (and still have them work for that matter?)
    • In a last ditch attempt to elicit mercy, Zim asks GIR, "You were my servant once, don't you remember?" to which GIR replies, "Yeah. I didn't like it." While it's possible GIR could have been referring to the short period of conflict he had with Zim while locked in duty mode (as he was able to see just how idiotic his master was), it also could imply that even when GIR is his own usual dumb self, that on some deeper level, he has enough self-awareness and sanity to realize just how terrible his life with Zim really is. That would mean that for all GIR's outward whacky antics, on the inside, he is constantly suffering and boiling with murderous hatred for his existence, though trapped within his own mind and therefore unable to ever do anything about it.
    • This episode serves to make the larger scope of the show itself much, much more chilling when you consider that GIR isn't actually "crazy" as the episode's name implies, but that he's actually functioning the same as all standard SIR units are supposed to. GIR's mentality and actions here are the same as within every other Invader's companion robot, all of whom have masters who are actually competent at their job. If this is just what the subservient robot slaves are capable of doing to a planet all on their own, just imagine how ruthless and dangerous the full force of an actual trained, sanctioned Irken pre-invasion mission must be.
      • Perhaps, but given that even before GIR turned on Zim his response to being ordered to investigate a siren was to smash the police car through the wall and abduct the officer for experimentation while demanding praise (to which Zim even states "That's not information retrieval") it's likely that even duty mode GIR is still broken and not acting like a functional SIR unit, just replacing random antics with random violence. His brain is still bits of junk after all. Or it could be it was a result of force locking part of his brain on a "dangerously high power setting". Either way a working SIR probably isn't as unreliable as even Duty Mode GIR.
  • The episode "Dark Harvest" was full of Nightmare Fuel already...then you remember what Zim replaces the hall monitor's organ with: a hall-pass. A hall-pass in the form of a metal collar that will explode if you leave school grounds. As soon as that kid starts for home or is sent to a hospital for his horrible stomach pains...ka-boom.
    • But he shows up unhurt in "Halloween Spectacular of Spooky Doom", so he must have survived somehow.
  • In "Bloaty's Pizza Hog", Gaz mentions that this is the only time all year she can spend time with her dad, due to him being extremely busy. A Tear Jerker in itself, but could years of Parental Neglect have turned her into what she is?
  • Considering how stupid everybody is, the only reason the Irkens haven't conquered the Universe yet is that they're also stupid, at least strategically. Can you imagine the Irken Empire with Tak in charge?
    • Partially confirmed, Tallest Miyuki seems to be the most competent leader compared to her descendants. She's the one who commissioned The Massive, and still kept the alliance with Vort.
  • More like a... Fridge Tear Jerker, but still: In “Backseat Drivers from Beyond the Stars”, Dr. Membrane mentions that Dib is always trying to raise the dead. Funny, until you realize that we never see Dib and Gaz's mother, it might be that Dib is desperately trying to make his family complete again...
    • Actually, if the show hadn’t been cancelled it would have been revealed that Dib was actually his father's clone, not his son.
    • If the clone theory is true, then where did Gaz come from? Is she too an experiment? Would that explain her demonic powers?
    • Even if the above is true, what if Dib knew a female figure who was like a mother to him who passed away? Jhonen did say something once about a "mom in a jar".
  • Besides telling stories about how she was once relatively normal, Miss Bitters also brings up history about earth before it became the Crapsack World it is. Considering she's supposedly exceedingly old, Bitters may have witnessed society go to absolute hell as she was turned into something inhuman.
  • “Mysterious Mysteries” has the flashback of infant Dib and Gaz. Dib has a bandage from an unknown accident on his forehead Gaz walks in just to kick down the blocks he's playing with. Gaz has been abusing her brother since they were babies.
    • This also asks again whether or not Gaz is...the way she is...because she finds everyone else annoying or that she's really naturally heinous. A mixture of both?
  • Nickelodeon decided that a man who writes extremely graphic and disturbing comic books about a homicidal maniac would be a good choice to create a cartoon for kids. Nickelodeon's channels are watched by millions of children, none of whom are supervised in any form while watching. Think about it...
    • I have to question the logic here. Artists can't create a variety of things? Did R. L. Stine become unsuitable for the Goosebumps series because he wrote Superstitious? Any director who makes a film that is Rated R can't also make a movie that's rated G? Seeing as I'd freely let my kids read the Johnny comics, I think what is happening here is a very subtle case of Moral Guardian...
  • In "A Room with a Moose" there is a scene where a possible destination for Dib is a universe of pure itchiness. Sure, that doesn't sound that scary... but itchiness invites the urge to scratch, and humans can seriously hurt themselves if they keep scratching long and hard enough.
  • The Nightmare Dimension from "Halloween Spectacular of Spooky Doom" is literally and metaphorically inside of Dib's head. That twisted, horrible place and all the messed up nightmares that reside inside it are created from Dib's scarred psyche. Just how damaged do you have to be to come up with those things?
    • It should be noted that most of those nightmares were based off of the people in Dib's life (Gaz and Membrane included) and not all just random creatures. Given what usually happens to him both outside and at home, what does this say about how Dib views everyone around him, at least subconsciously? What does this also say about how he might have been affected by their treatment of him?
      • In regards to this part in particular, Dib has a nightmare version of Nny from JTHM in his head. Why in the everliving hell would him of all people be showing up there (assuming it was not as a joke/cameo)? Does this imply that Dib had met or witnessed Nny off-screen at some point in the past?
    • Considering Nny breaks into other people’s houses a lot, then what is this shadow that can be seen lurking through Dib’s house here?
    • To be fair, that could just be the puppy Dib and Gaz lost.
  • In “Dibship Rising,” Dib makes the decision to rewrite Tak's ship with his own personality/mind. But once Dib-Ship figures out what's going on and recalls some past memories, it essentially decides to commit suicide. Just how much does Dib really hate himself?
    • Also, in an unwritten episode, Zim splashes Dib with goo that makes people explode when they're extremely happy. He never explodes and even explicitly says that he's never super happy.
    • And, just to top it off, let's all remember that Dib is only 12 and things are certainly not going to be lighting up for him...
  • So, on the fact that Gaz made security plushies that are supposed to eat human many test subjects did she use in order to make sure that they actually worked?
    • Also, seeing that Membrane was bummed out that he couldn't legally perform certain experiments in one of the unaired episodes, did he know what Gaz did and allow it? Did he also know that they could potentially harm/kill Dib ( probably one of the biggest intentions Gaz had in the first place)?
    • Here's a better one: do they not attack her simply because she programmed them not to...or is it because she herself is not exactly human (her occasional powers certainly don't help).
  • Being stuck in a room with a moose may not sound that scary at first, until you learn what kind of damage one moose is capable of doing. In fact, most people would prefer being attacked by a bear than by a moose. "Prepare your bladder for imminent release" indeed.
    • Furthermore, it's heavily implied that the wormhole leading to the room with the moose doesn't lead into the room itself, but rather lets out directly inside the moose's mouth, hence the demonstration with the walnuts. Zim was basically demonstrating that Dib and all his classmates were going to be eaten the moment they arrived with zero way of escaping.
  • When Dib uploaded his brainwaves into his new ship, the ship had such a perfect copy of the boy's personality it remembered Dib's entire life. Now assuming it's the same case with Tak, since it currently stores her personality, Dib has a perfect copy of an already vengeful and slightly unstable Irken trapped in his garage, used like a weapon in his fight with Zim. Tak-Ship has already expressed a desire to see Dib die a few times, so it's quite likely this imprisonment has made her personality even more volatile.

    Fridge Logic 
  • In "Backseat Drivers from Beyond the Stars," Zim says that his brain-eating parasite needs constant attention to prevent it from escaping, but Zim spent the last hour staring into a staticy screen doing nothing. And he spent the three hours BEFORE that trying to get the Tallest's attention. Surely the parasite would've escaped by then.
  • If Dib never left his room for 2 years where did he find the time to learn how to fly Tak’s ship?
    • Tak's ship can probably fly itself. Either that or Gaz, with her mastery of video game controls, figured it out.
  • In “Backseat Drivers from Beyond the Stars” Zim says that The Tallest are closer than ever before and attempts to steer them towards Earth. After he ends up controlling another alien ship and steers it towards Earth it’s not very long before the ship arrives. Yet in Enter The Florpus, Zim finds out that the Tallest are “schmillions” of lightyears from Earth and he has to employ space warping technology to get Earth to the Tallest.


How well does it match the trope?
