Awrighty!! Here's something besides my usual psycho-trippy-disturbing stuff. XD The is no pairing, only ZaDF, but I guess you could turn it into something else if you truly wanted to. ANYHOW I do not own Invader ZiM in any way. There. Ha!

ZiM: GET ON WITH IT! You're taking forever, human she-beast!

.....Right then.

Invader's FLU:

---

IN THE CLASSROOM:

"That space monster! He's onto something, I just know it! I JUST KNOW IT!" Dib thought furiously while staring intently at the small, green child, known as ZiM.

Though unknown to all of the other classroom children, ZiM in fact, was an alien: an IRKEN Invader to be precise. Bent on destroying the world, or conquering it, rather, ZiM became Dib's mortal enemy, as Dib tries to hinder the coming "invasion".

Dib, uninterested in Ms. Bitters' lecture, obsessively watched his nemesis' every move. ZiM looked worn out, which was odd; Normally he looked bored, and it was only the near the middle of class. The young irken boy was writing something onto a mechanical note pad, but what? Dib couldn't make it out from where he was sitting. The scythe-haired boy stood on his chair, gaining the attention of ZiM....and everyone else.

"DIB!! Sit down before I summon the discipline control squad to take you away!" The bitter elderly teacher screeched, causing his peers to laugh.

"Yeah Dib-worm-" ZiM chimed in " Before she-" he broke off into a fit of congested-like coughing. Kids began to stare, as the fit grew more violent with each cough, and the boy almost fell out of his seat.

"Ew!! Ms. Bitters!" Zita, a purple haired girl, squealed, "I think ZiM needs help or something!!"

The mentor growled, "ZiM! What did I say about dying?!"

The young IRKEN gained his breath, and wheezed, "Insolent fools! I-ugh....ZiM needs no...No help!...And..I am not...d-dying, either, Sir." he climbed back into his seat, mumbled something like 'ZiM is normal' and nodded to his superior.

"...Good." Ms. Bitters blinked indifferently, and continued droning on with the ridiculously boring lesson.

Dib however, did not dismiss the incident so easily. His amber eyes studied Zim once more, trying to comprehend what had just happened. He noticed that ZiM would grip the edges of his desk every so often, as if trying to prevent another coughing fit. The tiny body would stiffen, the relax, forming a pattern. Eventually, the little spasms stopped, and ZiM lowered his head to his desk, and slowly shut his lilac colored eyes.

"What? ZiM's never slept during class! ...I don't even think I've seen him tired!" Dib's mind raced.

The bell for lunch rang, causing all of the children to leave in an uproar. Except, of course, for ZiM and Dib. Which, again struck Dib as odd, because normally ZiM would have left within the wild crowd of students.

Dib approached the alien boy in a disbelieving manner, "Hey, ZiM. The bell rang."

His only response was the light snoring of the little green boy.

"Seriously, Zim. The bell rang, let's go."

The alien stirred a little, clenched his hand into a fist, and coughed, but nevertheless, remained asleep.

Dib was growing impatient with him, and began to shake ZiM roughly, "COME ON!! The bell rang!!"

"Awaaah!?" ZiM snapped awake, obviously startled, and glared at his trench coat clad peer, " Dib-stink, what do you think you're doing?!"

"God, for the last time, we have to go to lunch now!"

"Oh? Eh- ZiM knew that!! I was, uh, testing you!" he fought back a cough. "You pass-THIS TIME, worm-baby." And with that, pushed Dib out of the way, and marched down the cafeteria.

"Geez." Dib sighed, why'd ZiM have to be so...ZiM?

IN THE CAFETERIA:

Sleeping hadn't helped at all. Zim felt horrible, his throat burned as if someone had forced him to eat sand paper, and his head throbbed with a terrible headache other every step he took. He couldn't let the Dib know of this weakness though. Never in a million years would ZiM allow it. Invaders don't have weaknesses.

He stepped up with his tray to the lunch lady, as she (at least ZiM assumes a she) whammed some horrible, disfigured idea of a meal onto it. ZiM stares in a mix of nausea and horror at the dish,

"....Um, what IS this, exactly?"

"Monday special." came the gruff reply, "Why, you got a problem with it?"

''Uh-I no, sir!'' the lunch lady's eyes narrowed, " Uh, I mean, Ma'am! It-It looks delicious."

Zim laughed nervously, and scampered off to a nearby table. Sliding the 'food' tray away from him, he put his head down once more. And began to close his eyes.

"Hey, Space monster!" he heard a familiar voice, "Get up!"

ZiM made no attempt to look up, or even acknowledge the speaker's presence.

Dib (surprise, surprise) spoke up again, "ZiM! Get up! I don't know what you're up to, but I'm going to find out!"

ZiM spoke now, his voice scratchy and annoyed from the Dib's constant yapping, "Go away Earth-Filth. ZiM does not wish to converse right now."

Dib smirked, "Why not? Are you sick? Has the mighty IRKEN ZiM been brought down by a mere infection?"

"Leave me alone."

"Oh so you HAVE?!"

"Go away!" ZiM got up and swayed a little, bracing himself against the table.

Dib laughed, "You're little sympathy scam won't work with me, Zim. Quit trying."

Zim sneered, "I assure you I'm not faking anything, and why would ZiM need your stupid sympathy anyway? Mind your own business while I go be NORMAL somewhere else dirt-child." he turned away from his enemy, and began to head for the the doors.

Dib suddenly had a brilliant idea, and a mischievous grin worked its way onto his pale face. The boy grabbed an abandon milk carton, still full mind you, and chucked it over onto ZiM's head.

"KYYAAAH!!!" The IRKEN boy's skin burned horribly, as he pushed past and knocked over various things and students on his way to the exit.

"What a phony." Dib shook his head in distaste.

YEP!! Dibby doesn't believe ZiM isn't well, and ZiM just wants to go to bed. Anyways, thank you for reading, please, PLEASE review! & Ch. 2 will be up soon! Flames will be used to make treats for the poor, sick ZiM.
