Author's Note: I haven't written fanfiction in a really long time... and I think I've lost all of my previous readers. That is sad, I shouldn't have been gone for so long. I guess I just sort of lost myself for a long time. I guess the important thing is that I'm back now, and writing once more. I hope to update this fic pretty frequently, since I really do like writing very much. Anyway, on with the story!

Disclaimer: I do not own Invader Zim or any of the characters, so don't sue me. If I did own them, then the show would never have been cancelled. o.O

Chapter 1 : A Prelude to the Evil


It was a normal day, at the perfectly normal skool. The skool children were laughing and teasing those that were less popular than they were... namely, Zim and Dib. The two boys didn't really care, because the former thought that the other children were filthy humans anyway, and the latter thought they were all just misguided and mindless. They both just ignored the jeering of their peers, and proceeded to glare at each other from opposing ends of the classroom, just like they always did on normal days, never wavering. It wasn't until Ms. Bitters looked up from some paperwork on her desk that the children stopped their taunting, and even Zim and Dib stopped their glaring to give her their undivided attention.

"Class," she announced, "due to the school feeling that there is a lack of knowledge among you about the real world and the horridness of the natural state of things, a mandatory feild trip will be taking place tomorrow, and will be paid for using the excess money earned from the candy fundraiser that was held earlier this year. If any of you do not show up or refuse to go, you will be sent to continue the rest of your skooling in the boiler room." She took delight in seeing some of her students cringe. "For this trip we will be heading to the..." she looked down at a paper on her desk and grimaced before continuing, "...Sunny Happy Petting Farm." Upon saying this, a cheer came from 90 percent of the class. The remaining 10 percent included Dib, Zim, and Spoo, who was allergic to animals. Ms. Bitters glared around at the students, one of her eyes twitching slightly. Zim stood up at his desk, both hands raised in the air, waiting for her to acknowledge him. Ms. Bitters looked around the room, then spotted Spoo's hand. "What is it, Spoo?" she asked, ignoring Zim completely.

"Will there be animals at the petting farm?" the blue-eyed boy asked, his voice shaky. Dib rolled his eyes... what a stupid question. Ms. Bitters' eye twitched again, then she looked at Zim, who was still trying to get her attention.

"Yes, Zim?" she sighed, hoping that he at least had an intelligent question to ask.

"This... Petting Farm... is it an important part of human-... I mean... our culture?" the green child asked.

"Not really," Ms. Bitters answered truthfully. "But we all have to go anyway." Dib absentmindedly cleaned his glasses on his shirt. He wasn't particularly excited about this field trip, since there were more important things that he could be doing, like trying to sneak into Zim's base again, but hopefully it wouldn't be a total waste of time. The rest of the skool day passed pretty uneventfully, save for Spoo muttering to himself and shaking like a leaf at his desk at the thought of all the animals that he would be forced to encounter on the following day. Some of the other kids whispered to each other, saying that he seemed like he was becoming crazier than Dib.

"I can hear you, you know," Dib said, shaking his head in disgust. He heard someone snickering and then got hit in the head with a paper ball. Soon after this, Ms. Bitters ushered all of the children out of her classroom as soon as the bell rang. Zim marched down the hallway, planning to walk home. He hated the bus so much, and the thought of being stuck on it with a bunch of smelly human stink-beasts the next day did not make his hatred for the large yellow earth-vehicle lessen at all. He made his way home relatively unbothered, except for when someone's sprinkler came on, soaking him completely. He had forgotten to wear paste that day, but he discovered that the water didn't burn his skin quite as much as it had the first time he had encountered it. He pondered this for a moment as he wiped some of the water off of his forehead. Maybe he was getting used to this planet after all... Irkens had always been a pretty adaptable species, which is probably why they had spread so far and conquered so many planets. Even so, when he arrived home, his skin was a slightly darker shade from the water burning him.

"Welcome home, son!" Robo-dad and Robo-mom said in perfect, happy unison. Zim stared up at them and stepped over the threshhold, then was immediately tackled to the floor by GIR, his wig flying off and one of his contacts popping out in the process.

"Master! You're home!" The robot said excitedly, now hopping up and down on his master's chest. "Your friend called on the telly-o-phone!"

"Friend! What friend?" Zim demanded, standing up abruptly so that GIR fell onto the floor. "Zim needs no friends!" The robot giggled and wiggled around like a hyperactive weasel.

"The big-headed boy! He said that he's going to have soooome fuuuun with you tomorrow, and that there will be..." his high pitched little voice trailed off. Zim stared at him blankly for a moment.

"There will be...?" he urged GIR to continue, an eye starting to twitch.

"PIGGIES!" GIR shouted, grabbing at his feet in an infantile gesture, grinning widely. Zim sighed loudly.

"How did he get this number?" he muttered the question to himself, not really caring much about the answer, then without another word he stepped into the kitchen, then climbed into the toilet/elevator. He could hear the sound of the television being turned on, and some insane crazy noises as he descended into the darkness of his base below. The Irken pulled his other contact off of his eye, planning to hide it away with the rest of his disguise for tomorrow. His mind was somewhere else, though, as he stared at the curved walls of the elevator tube. In his great alien brain danced visions of a happy, sunny farm filled with cute little animals making squeaky noises. His antennae flattened against his head a bit, and a shudder ran through him. Too much... happy cuteness! It made his brain hurt, and what was the Dib planning? No doubt he was plotting against Zim's mighty mightyness, there was no other logical explanation for it. The Invader decided that he would not let his guard down the next day. He could not let the Dib-worm get the upper hand.


Meanwhile, Zim's nemesis was hard at work, trying to figure out what the alien was planning. You see, Dib had no horrible thing planned for Zim the next day at all, but instead was paranoid about what the Irken could possibly do at a petting farm, of all places, besides pet the animals. Zim had created horrible plots involving animals before, including fusing weasels with lasers, and creating a gigantic killer hamster. Dib couldn't just let Zim roam around a petting farm unchecked. With these ideas in his head, Dib grabbed a piece of paper and started to think like Zim.

"If I were an evil alien bent on human destruction, what farm animal would I use for my evil plan?" He asked aloud to no one in particular. He pondered the question for a minute or two, unable to really come up with anything.

"A bull, or the biggest pig I could find," a voice said from the doorway. His little sister was glaring at him in her usual way, smirking just a little. No doubt there were nightmarish thoughts of destroying the Earth while riding a giant pig running through her mind. Dib smiled just a little, happy that she wasn't telling him that his voice was stupid for once.

"Thanks Gaz," he said, writing the idea down, but when he looked back at his door, she was gone. It was kind of freaky, how she could just disappear like that, but at the same time... it was neat. He passed a few hours by taking the bull and pig ideas and just building off of them, trying to figure out what the little Invader was planning. Eventually, he fell asleep at his desk, drooling all over his notes and doodles. He slept peacefully, but little did he know that this would be the last peaceful sleep he would have until the following evening.
