Invader Zim is not mine; never was mine and probably will never be. Hell, if it was than it would still be running till this day. I just use Jhonen's creation to my own little stories while torturing his characters. This is what fanfiction is, and if it wasn't fanfiction, than why would it be posted here? It's not mine.

On another note, I don't know if this'll turn into a ZADR or not, but that'll happen many chapters later in the fiction. Not now, when there's filthy planets to destroy and worm babies to kill, oh, and maybe an empire or two to tear down bit by bit…so yeah, if you're a die-hard ZIM fan, and don't mind a little ZADF, then this is the story for you.

I'll warn you at the beginning of the chapter when there is ZADR, but after that, if you can stand your eyes bleeding from the screen, it won't happen again and the story shall continue. And by what I mean with that one chapter, well…they haz fluffy timez. Get it? Good. If you don't like that, GTFO. I will not acknowledge any "ews" or "gross" or "you're soooo sick!" from anyone.

Chapters vary in rating, this is PG13. Mild language. Enjoy~

Chapter One

SKOOL "SPIRIT" OF DOOM PART ONE

ZIM

The sun rose into the sky to yet another Monday morning, and the Invader hadn't slept for a moment the previous night. He slaved over one of the many metal tables, his eyes narrowed in concentration and hands moving frantically. A smile slowly spread across his face, revealing his sharp Irken teeth as his antenna wiggled with a sick jot.

"Finally…" he hissed. "Finally, the great and all powerful ZIM shall have this planet!" The alien threw back his green head and laughed a hollow, evil laugh that echoed through the lab. An alarm rang through the air, making the maniacal laughter pause and a pair of red eyes glance around the room. "Skool, of course that dreaded place would interrupt the almighty ZIM and his plans! No matter, it IS this 'Spirit Week' after all, which I could use to my advantage…"

Zim grabbed his black messenger bag and shoved his new experiment in among the notebooks stored within. He laughed once more, grabbed the wig and contacts, and then walked towards the platform while putting his disguise on. I'll start with destroying their spirits, then the foul skool, and then I'll be off for the life of Earth Zim thought, the smile still curving his face in an evil twist.

The platform brought Zim up into the kitchen through the refrigerator. He had to find a new location for the thing due to his growth in height. He opened the door, and a scowl replaced his smile. It had rained out, leaving puddles of acid all over the ground. Great, every time it rains I hate it more here…

Zim clutched the strap of his bag tighter as he began to walk down the sidewalk, avoiding any and all acid puddles and trying not to touch any of the wet. Ten minutes later, he came up to the High Skool's doors and pushed them open, thank full for his gloved hands protecting his skin from the wet that covered the handles. He glanced around, spotted the Dib human, and walked the other way, smiling at the fact that the worm baby didn't know what was going to hit the school today.

Opening his locked, Zim heard the clacking only metal-bottomed boots could bring and turned to face the eighteen year old Dib. The human stood a foot taller than him, which angered him so much his squidly spooch always quivered when he saw the enemy towering over him.

"What is it now, Dib-stink?!" Zim demanded, turning back to his locker to grab a useless History textbook for the first class of the day. Oh, how he hated listening to the teachers drool on about irrelevant dookie.

"You haven't pulled anything in a while, Zim." Dib said menacingly. "I don't know what you're up to, but you should know by now that whatever you're planning, it's not going to work. I'll either stop it, or it's going to fail miserably on its own."

Zim just smiled at him, narrowing his eyes in a promise that Dib would lose this round. "Why don't you just sit back and watch the show, filthy human? It's going to be promising…of course, I may not have planned anything at all. Who knows?" he replied, shrugging his shoulders casually than closing his locker.

"You wouldn't just sit back in an opportunity to unleash your 'doom' while the whole skool is preoccupied with the Spirit Parade everyone's required to attend. I'm not a fool, Zim." Dib said sourly.

"I know, human stink, which is why you might be of more use to me if you ever considered joining me. Just think, this pathetic little planet at our feet. Everyone who ever beat you, done wrong to you? Bowing and enslaved to do whatever you desire. You could watch the blood drain from their veins, if you so wished…" Zim whispered back. "This planet, these people, I wonder why you care when all they do is treat you like dookie."

DIB

Dib watched as Zim walked away to class, shocked at the turn of events their verbal fight went through. He expected something else, like being told he'd lose at trying to save the world again, which he was proud to say that he single handedly saved the ass of the world millions of times these past seven years. Instead, he got a would-be proposal to join Zim, and a basic slap in the face with the fact no one liked him.

Something's different today… Dib thought, walking to his class, the same one he shared with Zim. Room 212, American History, something he knew full well Zim couldn't give two shits about and would probably be using the time to think about whatever his plan was. Dib had four out of the eight periods to find out what it was before they were forced to the 'parade' out at the track. Need to come up with a plan, fast… he thought, walking into the room and sitting in his desk as the bell signifying the start of the period blared.

He glanced through the corner of his eye to see Zim already lean back in his chair, bag placed precisely in his lap as though someone might get at it. Dib's eyes narrowed. The bag…obvious, Zim, whatever you're hiding can be revealed if I just get your bag…

Mr. Kurds stood up from his desk in front of the class, and began telling everyone how unfortunately lucky they were to have survived yet another first week back at Skool, and regretfully welcoming everyone back to the second week of misery.

"Of course, this wouldn't be a problem for either me or you if they would just allow us to carve open your skulls and replace your small, peanut sized brains with computers that would do our bidding without complaining, but they unfortunately don't allow that much to my distaste." Mr. Kurds finished with a long, deep sigh. "But of course the government doesn't give us enough funds."

Dib covered his eyes with a hand, internally screaming at the fact he had to go through one last year, with this guy, before he could officially be done with this crap and move on with his life out of High Skool. He'd most likely go to college to become a ghost hunter, or some paranormal investigator, it didn't matter as long as he could group together a bunch of believing souls to take Zim down once and for all. That was what he needed. Not anyone who would claim he was insane, who pointed and laughed.

For a second, he thought Zim's offer, had it been real, would have actually been better than what he had now.

He should his head, shutting his eyes tight and holding the sides of his head with his hands trying to shove the thought out of his mind. WHAT are you thinking, Dib?! You need to save the Earth, it's your HOME, you don't destroy your home with your enemy!

He sighed and slowly opened his eyes. He was NOT willing to think about anything that would involve him and Zim destroying the world. No matter what happened between him and the morons who lived on it with him. The Irkens could kiss his ass, including Zim. Dib attempted to pay attention to Mr. Kurds and his lesson, but the period flew by without retaining much due to the fact he couldn't keep his eyes off Zim. The alien just looked so smug and sure of himself, keeping the back close by at all times and playing with one of the straps as the teacher drooled on.

The bell that signified the end of class rang, and everyone rushed out the door creating a jam of bodies that would last for thirty seconds before everyone could actually squeeze through and move. Because of this, Dib just usually stayed in his seat and casually picked his things up before standing and going over to the exit. He hated crazed crowds like this, what was the point? If there was a fire, everyone would kill each other from stepping on them to get out of the room.

These people are morons. Dib thought, scoffing at them.

"Dib stink." said a voice behind him. Dib whirled around to come face to face with Zim and his blue eye contacts.

"What is it, Zim? Don't you see I have other important things to attend to, like getting through that angry mob alive?" Dib replied.

"THE ZIM COMANDS YOU TO SHUT UP!" Zim shouted, clenching his fists at his sides. Dib wanted to laugh at the short guy, he was under average height for any human, basically a foot shorter than he was, and Zim was still trying to seems superior. Dib smirked at the alien. "What is with your face, filthy worm baby?!"

"The fact that your height matters to you so much. You may have grown, Zim, but just like in height and brains, I'm the superior one." Dib stated. He practically felt the heat and steam coming from Zim in his anger. For some reason, height always mattered to the alien.

"You know what, forget it Dib filth! It doesn't matter how much fun our little games are, such as the weekly battles and daily fights. Just because of that, you're going to perish with the rest of the Skool." Zim whispered, eyes so narrowed they were practically slits. He walked out of the room, the mob at the door had dissipated.

ZIM

That was lowest move in the books, and Zim was fuming. It was true, he thought the battles between him and his enemy were fun little games. It didn't matter much, the Irken Armada was approaching soon to destroy the little mud ball planet and its inhabitance, so whether or not Dib stopped him or his plans failed miserably, the filth stink would be prey to Zim's people.

Zim decided to skip class until fourth period, not wanting to be in another room filled with the worm babies and Dib. Ohhhh, how the Dib human was going to pay!

Glancing around the corner to the only door leading outside without a camera, Zim saw no one blocking his path and bolted out into a back alley and bolted out into the nature path behind the school. Normally, teenagers hung out back there to smoke and get drunk, but Zim wasn't going to stay on the ground and tolerate that filth.

His spider legs came out from his pack, and with them he climbed up a thick, tall tree and picked a spot to sit and wait. Zim dug out the device he slaved over for the past week and checked it over, wanting to make sure his plans would work precisely to how he expected them.

Complete the mission, go back to base, call the Tallests, and be acknowledged for his greatness for being the almighty ZIM!

The round ball he held in his hands would get him to where he wished, and even Dib would be unable to stop him. Its surface was slick and smooth, the color that of what humans called maroon. Light blue veins pulsed around the surface with energy, and it was heavy to carry due to what it concealed.

Zim chuckled, than heard a gasp from below. The Irken frowned as he glanced down and spotted Dib watching him from the ground. Zim glared at the unwelcome being, and shoved the device back into his bag.

"Why are you here, FILTH?!" Zim commanded. "I thought you didn't want to spoil any perfect attendance record?" Speaking of attendance, the bell for the next class rang, echoing towards the foes. Dib grimaced, and Zim smirked at his pain of being marked tardy. Such a pathetic perfect student.

"You left Mr. Kurds room first, but when I got to math you weren't in your seat Zim! I knew you were planning something, and now I know it's got something to do with that…with that…ball thingy!" Dib yelled, knowing how stupid 'ball thingy' sounded.

"Go back to class, Dib." Zim said, smiling. "You'll find out what this thingy does in no time!"

Zim heard the High Skool's security guard before he seen him appear, grabbing Dib. The Irken scrambled around the tree with his spider legs, hiding at the last second.
