Okay, this is my first ever fanfic, and if you don't like it, too bad! Don't read it! This is a story about Zim and Gir's first summer vacation, and there are going to be many chapters!

Summer Invasion

Prologue

Tick…Tock…Tick…Tock…

Zim growled. How dare that clock keep him waiting! What power did it have? If only lasers were allowed in this shark tank the humans called "skool"-he would've destroyed that infernal contraption from day one.

'Oh well' he thought, 'At least this is the last day I have to hear it…although, I would've enjoyed destroying it…'

Zim hadn't learned everything he should've about human schools, so he thought he would only be there for one year at each school. He was convinced that this was his last year in grade school.

He looked around at the filthy human-worm-babies surrounding him that he was supposed to have befriended…as if that would ever happen! He was far more superior than them, for he was Zim! He hated them, and they hated him. They had called him many dirty names during the year.

That's when Zim grinned, a nasty plot for revenge forming…he was going to get back at those name callers by playing their game.

Zim poked the Dib-filth in the back of the head with his pencil (Dib had been a major name caller that year).

"What?" Dib hissed.

"You're a duck." Zim hissed back.

Dib blinked, confused, then whispered "I'm a…duck?"

"Yes! You are a duck!" Zim announced loudly. The rest of the extremely bored class looked over, itching for excitement.

Meanwhile, Zim was being very proud of himself for remembering that Dib had called him that…or was it something else? He had a growing feeling that wasn't the right word.

"I don't have any idea what you're going on about", Dib hissed threateningly, refusing to raise his voice, "but I swear to you, that if you make me look bad in front of my peers, I'll hunt you down and-"

"DIB'S A DUCK! GAZ IS AN ITCH! YOU'RE ALL-" Zim started screaming, but was interrupted by the bell.

"YES!" He screeched. "GOOD-BYE, STUPID HUMAN CHILD FILTH!"

Zim then proceeded to race around the room in circles, laughing manically, before racing through the door and out of the skool. He was so absorbed in himself, he forgot his backpack. Dib noticed this, then grabbed it, opened the window, and threw it so hard at Zim that it knocked him down, and landed on top of his head. Even with his head under the backpack, Zim continued laughing uncontrollably.

The dumbfounded teacher blinked, then said to the class (who were staring openmouthed at Dib, Zim, and/or the window) "Um, well, you are dismissed…have a great summer and (she lowered her voice) watch out for him…I think he's psycho!"

"I heard that!" Zim screamed, before racing off with Gir, who'd been hanging around at the playground in the back of the skool.

And so began summer vacation.

Okay, I hoped you like that! The next chapter will be involving pools or playgrounds...or both!
