The Speculative Analysis About Irkens No One Asked For: Part II

Hiya! Back at it again with not shutting up about the lil green dudes. In case you found this first, here’s the Part One of this spiel, touching on some of the environmental theories about Irk and its cyberpunk-leaning cultural direction. While this post is dedicated to a more biological look of what’s going on with the Irkens, there was some leading context and other tidbits back in that one you may also enjoy, too.

So, carrying through what we previously set up, I want to… admit off the bat that, I found it a little difficult at first, you know?-To pick an angle I wanted to sink my teeth into. With how old the show’s become and how creative & enthusiastic a fanbase it attracted, it’s getting hard to really note (or theorize) something about Irken anatomy that hasn’t been said before somewhere. And don’t get me wrong, that’s awesome and I love almost every word of it I’ve read. A lot of it from various sources is almost certainly going to bleed together into the first half of this. So, keep it in mind, yet I will try to chew a little deeper into the questions we can’t actually answer with just a rewatch of the show, all good? Because there’s a few more base things we know from the canon I’m going to include to start listing: - Irkens lack any visible form of nose or ears, but are equipped with a pair of sensory antennae. Presumably, these organs fulfill the same roles, as they do in real-world insects. - Irken organs are obviously very alien, not well explained, artificially enhanced, and hard to compare to that of a human’s- outside of their general body shape, the presence of a primary brain separate from the PAK, and the fact that they do possess something of an internal skeleton. - A petite race on average (relative to humans), Irkens universally follow an unquestioned social hierarchy based on individual height. - Irkens are endowed with a remarkable ability to regenerate and heal superficial injuries, even up to repairing the damage of being nearly skinned alive (chest-down) or severely burning their corneas within a matter of hours. - Their preferred diet is one that is rich in (if not primarily made of) refined carbohydrates, and while they seem to tolerate fatty sources, such as processed dairy, their anatomy is poorly suited for dealing with high-protein foods like beans and meat. - In fact, all forms of contact with exposed animal meat itself will cause it to dissolve and meld into their own flesh, via an incredibly painful process. - On contact with water from Earth, their skin will receive harsh chemical burns (This has been explained by Vasquez to be a consequence of impurities and man-made pollutants, which Irkens seem sensitive to). - While I’m already on a roll about their skin, it also contains/produces a substance capable of killing lice.

Now, I think we’ve all heard a lot about sqeedily spooches, but does anyone else want to keep marinating a second longer on the topic of s k i n ? Because I have some damn thoughts to release about Zim’s outer casing.

Let’s Get Chemical

First hot take, and the hill I am willing to be slain on: That ain’t actually skin! At least, it is nothing chemically alike to Earth-native vertebrate skin. I’ve given all of the above and the general running theme about Irkens resembling arthropods a lot of thought, and I’ve come to about the only conclusion I could that makes their dermis equivalent… make sense.

See, one of the biggest traits that sets apart invertebrates from other animals in real life is the “innie or outie” skeleton question, but you gotta understand that the “skeletons” that bugs and crabs have would still be considered something completely different from our endoskeletons even if they were on the inside. The hard tissues that make up OUR skeletal systems are mostly made up of a *collagen (remember that word!) frame that is reinforced by calcium, phosphorus, and other minerals. The hard parts of an ant’s skeleton, on the other foot, are mainly composited of chitin.

Chitin, now, is a very neat substance. It’s a polysaccharide, meaning that it’s made up of a bunch of sugar molecules chained together. This makes it distinct from proteins, which are made of amino acid chains instead of carbs. Chitin is also one of the single most important structural polymers in the universe to a ton of existing life. It makes up the literal backbone of arthropods and the cell walls of all fungi. We’ve even found it in fish scales and some amphibians. So, must also be important to humans, right? NAH. Not a chance. Higher animals actually long ditched the ability to synthesize the stuff, and are not any the worse for it, since there’s more than one way to stick a bunch of creature pieces together. For two examples, keratin and *collagen are proteins we naturally synthesize that functionally do the same thing. Keratin is the hard substance that makes up hair & fingernails, and collagen is practically the wonderglue of flesh: It’s a fundamental binder that holds together your bones, your skin, your precious muscle meats, the ligaments, the tendies, the nerves…

pretty much the whole person blueprint if you get the picture.

And thus concludes your (VERY overly simplified) highshcool bio class recap, but what the hell did that have to do with the cartoon spacemen again? I’m gonna round back to them through a funny secret about exoskeletons, actually: They have a softer part, too! Chitin’s hella diverse in its forms and utility. What’s in an exoskeleton is actually a version of it modified with other materials (like what’s done to collagen in bone) to make it so rigid and shell-like. A purer chitin, on the other hand, is more leathery and flexible, less like the shell of a beetle and more like the squishy wall around a caterpillar or maggot. Even the hard bodied insects still have an endocuticle layer like this hiding just under the “shell”, still considered part of the whole exoskeleton, but suddenly looking and acting more like we’d call a skin.

Eh, see where I’m going with this? My conviction is this- Irkens may have used to be even more arthropodal in an earlier stage of their evolution, including BOTH an internal skeleton, and some form of protective exoskeleton in their body plan. And hey, maybe the two were extensions of the same system once, too. You recognize something like that in modern tortoises when you remember that their “shells” are actually just the bone structure of their own ribcage. Then, let’s say that Irkens later saw the loss of their heavier exocuticle, leaving behind the endoskeleton and the flexible inner (now just an outer) cuticle of what used to be an entire body shell. This could have been a gradual change, via natural selection, or it could have been another artificial mutation brought on by technology- wherein the elder brains decided the feature was less efficient and simply phased it out of the cloning process- the same as the loss of their species’ sexual organs.

But, you’re thinking, why on Irk would the loss of an entire badass armor layer be beneficial to their fitness? Few reasons- For one, they are cumbersome and limiting. The downgrade on freedom of movement and flexibility they would be for a bipedal humanoid is self-explanatory enough. When it came to structural integrity, the inner skeleton would have already done a well job with little modification. For all the protection they provide, they don’t leave much room for expansion, and need to be shed in order for the animal to grow any further or to recover from certain injuries. The process of molting itself would be an excruciating process for any intelligent species to have to endure; one that also temporarily leaves the critter in a very vulnerable and stressed state for every molt. To advance from more primitive origins into a dominant race, manual dexterity and mobility would have to take a front seat over a small amount of modest defenses, and mind you, Irk long ago woulda managed to compensate for that loss in the form of advanced weaponry (obviously).

I’m also of the mind that the shift away from an exoskeleton could have even been the key to allowing the Irkens to even grow to the size they are now. Recall back to Part One for a second, where I shared the likely case for Irk having a massive bulk behind its gravity field. Gravity is a hard thing on any skeletal structure, representing a constant strain to be fought against when moving, growing, and bearing weight .There’s a lot of factors behind why we don’t have horse sized spiders or elephant sized lobsters IRL, and weight is actually one of them. Notice how terrestrial isopods only get about to the size of a bean, but the aquatic ones can top out at over a foot long? And that’s only having Earth’s level of gravity to struggle against, let alone however harsh the conditions would be on a larger planet. So, there’s my framework for explaining what I think the aliens’ cuticle is not; however, what does that mean for what it is, besides “feels and looks like a grub’s”?

Well, look again at some of the extraordinary things it can do.

Cooties Immunity

“Germs” was a memorable episode that posed a very legitimate question to the viewer. Why IS IT that foreign pathogens aren’t a bigger concern for the invaders? They’re literally sent off to other worlds to blend in: Socializing with the native inhabitants, eating their foods, and living in an alien habitat. In the case of an undiscovered rock like Earth, our infectious diseases would have no reference available to the Armada whatsoever. Sure, species incompatibility would provide some protection, but the risk of something carrying over and adapting is always still there. Zoonoptic jumps happen all the time with bacteria and viruses, and Zim’s body temperature IS in the normal human range. And what about fungal pathogens, or parasites-

Oh, wait, the lice episode gave it away right there.

I love this sequence so much, because it’s coincidentally like, an exact “art imitates life” parallel to something a real species of primate does. Black lemurs live in the same area of Madagascar as these vibrant, red millipedes.

The millipedes are special because when threatened, they secrete a poisonous substance from their skin. The lemurs are special because they like to grab the bugs and nibble them for no other reason than to make them release those toxins. Those chemicals are then rubbed into their fur, because somehow the lemurs figured out it makes a really handy mosquito repellant. The lemurs also like to get completely zonked out on the chemicals too but eyy- Point was it stands to reason that Irkens may also secrete small amounts of their own potent toxin from the cuticle, perhaps for more hygienic than defensive purposes. This secretion would be responsible for protecting them from parasites and topical infections. Could it also make people blazed out of their minds? …Maybe? I think I’d like to promote the “Just Say No” policy on the matter of licking aliens, though. Ffs at least ask them out to dinner first.

When it comes to other kinds of sick, looks like it might be the trusty old PAK to the rescue here again. I imagine that, being an intergalactic, partially mechanical civilization, the Irken race has come down this road enough to put in a workaround. A standard PAK contains the entirety of the population’s collective knowledge/history- which would include a catalog of all known infectious agents they have encountered across the universe. Some kind of nanobot-bolstered immune system that could detect and respond appropriately to new threats isn’t out of the question, nor should a feature that can automatically administer the appropriate medicine directly into the wearer’s bloodstream. For all this awesomeness, nonetheless, there remains a downside or two that they haven’t quite conquered..

The Meaty, Sweety, Mending of DOOM

Anyone ever actually think about how as far as resilience is concerned, Zim is practically an X-man compared to any Earthling? He has regenerative capabilities that surpass anything else on earth, save idk, bamboo shoots, if even. Injuries that would leave a human permanently disabled only seem to incapacitate an Irken for a few hours to a day at most. They’re all the more tough to put out of commission when considering that a PAK doubles as a form of backup life support, ready to “soft reboot” the host with a quick jolt if it detects a sudden drop in vital signs. It is tempting to credit the same device as the source of this healing boost as well, teasing the nanobot suggestion again; however, I see a chance instead to bring this back a step.

Although not as quick-acting as Zim, or Skoodge’s healing, there are some remarkable examples of regeneration in real arthropods, from repairing tissues/organs to replacing entire lost limbs. What the aliens are packing doesn’t seem all that different, only refined (through years of bioengineering) to work at a truly frightening efficiency. It shows through in their diet as well. Almost always, if we see a member of this species eating on screen, and believe me there was no shortage of examples, what are we watching them shovel their face with?

Space doughnuts, space popcorn, space Fun-Dip, sodas, and curly fries. Sure, there’s plenty of calories here, no doubt with the amount of carbs and grease that could even turn the stomach of a college freshman, but is this… nutrition?

Yes. Just not for us.

Like their civilization, we have also turned the mass production of sweet-packed, fat loaded foods into one of our favored art forms, and there are scattered pockets of our planet that can enjoy these items in cheap abundance. The catch 22? Obesity and heart disease. Meanwhile, Irkens are so metabolically blessed that they can follow the same lifestyle and actually be thriving by it. We know that the majority of human food is utterly toxic to Zim, but then there were waffles, a literal stack of dessert and butter that pretends to be a breakfast…. Our guy was experiencing the “finally some good fucking food” meme from the first bite off that plate, but this can’t seriously be healthy,or if it is, then how?

Well, if I did sell you on the idea that much of their tissues and skeleton swaps out a chitin base where we would be using protein, there you go. Sugars for the building blocks to synthesize the connective/structural tissues for maintaining the body, and the bulk of the energy required to keep it running. And I won’t make the leap and suggest that’s all they have.

After all, the Irken equivalent of sandwiches do actually seem to contain “lettuce” and something that people will say looks like meat slices while not convincing me. I can get behind the thought of the natural or maybe original Irken diet to be a mix of plant matter and supplemental fungi, but everything I’ve put together implies that they are completely unfit for processing the goodies in animal flesh.

Overwhelmingly, I believe that the only time they possibly even seek out more sources of amino acids is going to be when they are smeets. That’s how it works in many wasp species. I.e. The growing larvae are the only ones that actually get to reap from the hard work of a colony hunting down enough protein to feed them with, yet the adults live out the rest of their lives more than content to gorge themselves on nectars and fruits exclusively!

And you even could put that aside, but you’ll have to grapple with the ungodly thing that happens every single time you see Zim touching a piece of meat. Would be awfully convenient to blame it on his personal brand of weirdness, or earth contaminants, but we remember this was a weakness that Tak approached fully aware of and expecting.

We know that polluted water can burn them. We know that beans and other foods can give them grotesque allergic reactions. Well what in the horrifying name of Resident Evil is this, though? Buddy pals, I think we got some unintended consequences of that bio-hacking on hand. Collagen and chitin aren’t just functionally similar to each other, they are practically analogous building blocks.

For a WILD science fact, consider that there’s a ton of ongoing research into the application of chitin and chitin-derivatives into having a role in tissue engineering, as a hypothetical scaffold in lab cultured meat, and as an effective wound dressing ingredient.

What we’re seeing with incidents like Dib throwing that Bologna at Zim could be an extreme form of the vise versa, because I know a certain protein that processed meat happens to be pretty high in :)))

Imagine the coupling of this with the bioengineered genome of Zim’s kind being so… reactive to a foreign intrusion, yet also flexible to modification. Maybe it is the acids, or some contaminant/seasoning on the meat that first damages the cuticle. That healing ability kicks in, but doesn’t stop where chitin does, readily binding to and with the collagens in these strange tissues that are sorta like an Irken’s but also just enough not like an Irken’s that it also kicks the immune system into overdrive. Think of all the pain and inflammation of a poison ivy rash but if the damn plant itself could also fuse itself with whatever you brushed against it. I think Zim actually had an understandable reason to be homicidally pissed off for that Bologna assault. Also how the Bologna virus was accelerated in Zim’s body. Once it had incorporated itself into his own DNA, it was game set and match with the speed and help those cells had to replicate themselves.

And uh, yeah, I think this post has gotten about as long as it reasonably should be here. I did have a couple more points I really wanted to get out of my brain about the Almighty Tallest, and I think that would be a good launching point actually for a possible (and hopefully final jfc) part three to this. Till then I got some off-topic scoliids to taxidermy 👀

The Aurilian Organism is a unique species native to the planet 34 Cygnus c, informally known as Aurilia after Exocartographer Matthew Auril, who first charted the planet in 2112. 34 Cygnus c is an Earth-like exoplanet approximately 1.4 times the size of Earth orbiting a binary star system. Water oceans cover approximately 82% of the planet's surface, while its surface temperature averages upwards of 52 degrees Celcius at the equator. The combination of high surface temperature and large water area drives the formation of large scale hurricanes at all times of year. Though 34 Cygnus c's atmosphere, composed mainly of nitrogen and oxygen, is generally similar to Earth's, the presence of elevated methane levels necessitate the use of respiratory equipment on the planet's surface. This, combined with the planet's higher oxygen concentration, leads to frequent and abrupt firestorms that can scorch dozens of kilometers at a time. These generally hostile conditions have led the United Nations to declare the planet not suitable for human habitation, and surface access is currently restricted to scientific expeditions only. 34 Cygnus c has an active biosphere. Multicellular life emerged on the planet approximately 3 billion years ago, and most of the planet's land area is dominated by large rainforests populated by xenofungal flora. Most flora have adapted to the planet's frequent firestorms by developing a rapid growth cycle, and entire forests can regrow from seed in a matter of weeks. Planetary fauna is entirely invertebrate, resembling large, soft-shelled arthropods. The Aurilian Organism is the dominant species of 34 Cygnus c, and is believed to have first emerged in its current form approximately 720 million years ago. The Organism in its current form is a gestalt composed of two distinct species in an obligatorily symbiotic relationship: Mnemosynus pyriti, a xenofungus resembling certain terrestrial lichens, and Melpomenia similis, a highly eusocial arthopod-analogue (commonly referred to as Aurilians). Mnemosynus pyriti is able to mimic almost all of the pheromonal and electrochemical signals which Aurilians use to communicate. While this may have originally evolved as a defensive mechanism, both species have since evolved to be entirely co-dependent on one another. Aurilian hives work to promote the growth of Mnemosynus pyriti, which in turn provides shelter, nutrition, and a form of distributed eusocial intelligence (see below). Aurilian colonies possess a social structure superficially resembling those of terrestrial ants or bees, albeit with a greater degree of sophistication. A number of specialized castes exist, with a great degree of physical variation between individuals depending on their designated role. Castes also differ greatly between colonies, which suggests that colonies are able to alter the forms of their drones in response to environmental pressures. Regardless of their caste, all members of a colony are able to communicate with one another via a combination of electrical, pheromonal, and auditory cues. Together with the communicative properties of Mnemosynus pyriti, this creates a form of organic network connecting all drones to one another, with lower castes directed by specialized coordinator drones who, in turn, receive orders from each hive's Queen. Unlike terrestrial insects, Aurilian Queens are not only responsible for procreation, but also serve as a form of central intelligence for their colonies. Though the extent of this control is not yet known, the Skipper 14 Incident indicates that a colony's temperment is determined largely by its resident Queen. Individual colonies have demonstrated a capacity for memory and learning, and information is preserved between successive generations of Queens; while the mechanism behind this is not yet fully understood, evidence suggests that the memories and temperament of a Queen can be retained in a colony's mycelial network to be imprinted on any future Queens, as demonstrated by the Phoenix Valley colony.
