A/N: Alright, due to a few recent reviews, I'm adding this part to the beginning. Mainly since I don't think the people reading have kind of understood this, I'm laying it out now.
The point of my writing it is to make it very clear that both Tak and Zim are evil, and if you think they're not, then you're wrong. They routinely assault Dib, both mentally and physically, commit horrific experimentation and vivisection on humans and are trying to destroy Earth.
Tak and Zim are Evil, and everything they do is pretty much evil. They are not to be looked up to, or considered 'good' character's in any sense of the are the villains. Please remember that.
The day it begins is the day that she returns to class. A pit opens, another filthy worm child sent to whatever dimensional hell pit the thing in charge wishes, her disgusting boots trampling all over his planet – His – stomping out to His chair in His classroom.
A disgusting, filthy impudent creature with disgusting purple eyes and that horrific tube sticking out of her head and those beady little inserts that are so much worse than his own. A mockery of teeth and flesh, hidden by lights and lasers, a terrible, disgusting creature.
He hates her.
Oh by Irk, by all the Tallest he seen, he's praised and served, he hates her.
The way she walks, stomping around like she's so much better than every other mewling, disgusting pig creature that waddle the Skool, with her rugged boots kicking and crushing those pork digits that the vile, rotten humans wriggle around with.
The way she pushes and shoves and scowls at them, like she's better than them, digital lights and solid energy covering her claws, beneath glove and light, knocking them down into the foul, tainted muck that they live in. Not even caring if they get up, or their bodies are wrecked, or their flesh is peeled off like some kind of fruits. Nor when she tries to take control of the Skool yard, with her mind and her sickening, repugnant eyes with their flashes and their colours.
Even when she thrashes the Dib, she's still a horrifying, revolting, filth-encrusted, repellent, icky, trash creature. More so than any of the humans, she's the ugly one, the dirty one. Crawling with not just the germs or the bugs or the filth, but because she's an Irken, and she knows that she's filth and she'll always be filth because it's written into her very code.
Oh, the blood on her fists and face when she pummels the monkey creature into the dirt, ichor across her ugly face. It's hideous and disgusting and vile and worst of all, he can see it happening.
He hates her.
The way the Skool rallies around her when she stomps on the Dib's soft, wriggly, wormy claws, laughing at the boy and his broken glasses. The way he yells and screams at her, bashing her across the face like he knows how to fight or to kill or to even hurt her properly.
It's disgusting that he even tries. Even more so when she doesn't even fight back, the entire Skool yard howling like some kind of side dish to the primordial ooze that they crawled out of, yelling and punching and beating the Dib. Even when he jumps in, punching and swinging and clawing at them, each of them, all of them, he knows that she knows what she's doing to him.
So when he finally rakes his claws over the eyes of some pitifully little insect, clawing and baying to wring and stretch and stroke her thick neck and gnaw and tear and rip at her antenna, cutting and pulling her flesh and eating her irksome bones, she'll know what she did.
But he's an invader. The telemetry and the beeps and the endless lines of code deep inside his brain tell him that, no matter whatever the primitive readings that come to him say. He was is an invader, and no code can ever rewrite that.
So when he finally scuttles his way over the mound of mewling children, she thinks she knows what to expect. That he'll fight and hurt and bite, because that's what he would do, what she would do to him.
But he's better than that, and he'll show her why he's better than her, so much better, because he knows how to truly show how low and how filthy and how disgusting she is.
He lifts her up off the ground, arms wrapped around her neck. Her thin, easily choked neck. Brushes down her stained jacket, rubbing his finger on his tongue and wiping away some off the dust on her cheek and gouging straight through her jaw. Finally, and she knows that he knows that she is reeling and writhing and twitching under his gentle touch, he pulls her in close to him, with his head under her jaw and sings praises to how good she is, like she's some kind of Tallest, like he's admitting she better than him when they both know she's not.
The way the crowd of humans coo and aw at her is the most degrading, the most unimaginably grand insult he can lay on her, because now they think she is weak and small and that she needs Him.
But most importantly, she knows that he knows that she wants to be Just. Like. Him.
So she smiles, bends her head and she lays her lipless mouth onto his own like she actually cares for him, and he feels her razor tongue flick across his own and cut him open, turning the inside of his mouth into a carnal mess.
And the humans have no idea that they hate each other, because humans don't hate, not like you're suppose to, not like Irkens Hate. They're so caught up in the Love and the Passion and the Romance that they think that the two might actually love each other.
So they hold hands and they hug and every pathetic, mewling, sickly, Pathetic, Worthless Human thinks that there go the two happiest children in Skool, because they Love each other.
They don't notice the claws digging into each other, the pink fluid as it drips from their closed hands, stabbing one another through the skin and muscle, begging the other to cry out so they can speak up and offer love to the other. Instead they see the pair wander about holding hands like some cute couple from the mindless, mass-produced dreck they endlessly consume.
They don't see the subtle twitches of agony that runs up their limbs as they kick each other so hard that their own irksome bones crack; just in order to hurt the other. How each of them staggers and hisses at themselves, because they can't even walk due to the sheer agony from their shattered limbs. Instead they see lovers that can't bear to be parted, that can't stand without the support of the other.
And then, in the months that come, they don't see as they try to kill the other, the sheer agonizing hate that the have for one another driving them to it. In the darkness they roll and they bite and the pull and they cut and the hurt, because that is what Irkens do when they hate one another.
Not like one hates a lesser creature, like a human would some beast, or some food or one another.
No, Irkens hate one another with such passion that one can only hate themself with. Like a human would love another, that is how Irkens hate. With bloody bites instead of light touches, with violent, horrific scars instead of gentle memories, with one standing over the mangled corpse of the other instead of slowly growing old together.
And they both know it'll come.
How it'll end.
One day, she'll stand over his own body because she is bigger than him, stronger than him, that she is a she, and that is how Irkens are supposed to work, and then she'll die. Because that is what Irkens do. They hate, they consume and they die, only for it to happen again.
But for now, they'll hate one another on this disgusting mud ball. They'll fight and they'll bleed and they'll curse one another, they'll hate and scream bloody murder at one another.
Because Tak and Zim hate one another.
And they would have it no other way.
