Disclaimer: I don't own Invader Zim, Jhonen Vasquez does. I only own this story and if anything I write resembles anything that already exists, it is coincidence and I don't mean to copy anything.

I know the whole "Hi Skool thing is over used but I didn't want some of the things that happen in the story to happen to a bunch of ten year olds. If people message me about it, I might write a lemon in later chapters.

Anyway, Zim (Looks 18) is in his senior year of Hi Skool along with Dib (Age 18) and Gaz (Age 17) is a junior. My OC named Rayne (Age 18) is also a senior. Thoughts are italicized.

"We know Zim, but it is important that you get more information on the humans before we can arrive with the armada." Tallest Red explained.

"But my Tallest, I've been on this discussing planet for eight earth years. Don't you think that I, ZIM, have been here long enough to gather enough information on the humans for the armada to easily take over?" Zim questioned; his crimson eyes distorted into a look of disappointment.

The Tallest seemed to be in thought. It has taken him years to get them to finally listen to him; his new, staggering height of 5'10'' helped with that. Although he is not sure what brought up the growth spurt; but whether it was natural or because of being on Earth for so long did not matter to the Tallest. Not only that, but Zim has also become more mature and sensible over the years. Though he did, still, have his childish outbursts on occasions. Tallest Purple cleared his throat, breaking Zim out of his thoughts.

"Zim, we know that it has been a long time but we still need better knowledge on the weaknesses of their species." His tone was more serious than his usual, uncaring tone he always possessed while speaking with the young Irken.

Zim let out a subtle sigh of frustration, he hated being on this planet and wanted to be done with the mission so he could finally return home to Irk. Over the years he became home sick, feeling slightly lonely for the first time in his life. Sure, his loyal companion, Gir, was there to keep him company, but wasn't fit for a healthy, intelligent conversation. Zim composed himself once more before speaking again, trying to break himself of the habit of getting easily irritated.

"What do you suggest that I do?" He asked. The Tallest turned away for a moment to speak with each other, occasionally nodding their heads in agreement with their co-Tallest's ideas before finally returning their gaze to Zim.

"We have decided that the best course of action is to capture a human for questioning." Tallest Red stated, smirking at their ingenious plan.

"Although, we would suggest a human whose absents would go unnoticed if they were to disappear for large amounts of time." Tallest Purple added.

"Then I have much work to do. I will report back once I have found a suitable human." Zim announced, spitting out the last word with as much disgust as possible; and with that the Tallest's screen went black.

"Should we have told him?" Asked Purple. "No, he doesn't need to know right now. However, I NEVER thought we would ever have to tell him. I always thought he was a defective unworthy of such a privilege." Replied Red, turning towards his colleague.

"I know what you mean, I mean, who would have thought he would actually start to become useful." Purple snickered.

They both laughed, bringing back memories of Zim when he first went to Earth. It was astonishing, the amount he had grown over the years; coming closer to their height of six feet.

"I guess it is understandable, considering he's-" Before Purple could finish, a tall, orange eyed Irken guard ran into the room.

"My Tallest, we have an emergency! We need you back up on the Bridge!" He exclaimed. The two leaders looked at each other before rushing out of the room, following the guard back towards the control room.

Zim paced the floor of his lab, thinking about what the Tallest had said. Although he was grateful that they were now taking him seriously, he was still angry at the fact that not only did he have to stay here longer, but Zim also had to find a human that fit the profile that the Tallest suggested.

"Computer, bring up the bios of all the students at that horrible learning facility." He commanded.

"Yes, sir."

It took only a matter of seconds before all the students profiles were brought up onto the screen. There has to be someone who lives alone by now. Most humans, as Zim has come to find out, usually started living on their own at this age, so it shouldn't be too hard to find one that was. As if the universe decided to work against him, there was no child listed that didn't either still live with their parents, or live with a so called 'roommate'.

"Damn!" He cursed, slamming my fist down on the controls.

Zim looked over at the clock to see that it was 7:35 AM; class started at 8:00. He grasped the microphone next to the keyboard. "GIR!" He called. "Yes?" Gir squeaked, poking his head from a vent in the floor.

"I'm going to the human learning facility; do not touch anything while I'm gone. Do you understand?"

He stared at his master for a second before running out of the room screaming something about a beaver. Shaking his head, Zim grabbed his disguise off of a lab table and threw it on, unenthusiastically. About two years ago, he decided that it needed some work to help blend in more so his old wig was replaced with a style that he has seen many human males use; short and more spiky. Zim also started to wear an assortment of human clothes. Usually it was, either, a black or red shirt and a pair of jeans; although he had to modify the shirts to account for his PAK. Zim exited his base and slowly walked to Hi Skool; he hated going and having to be surrounded by the dirt beasts that plagued the pathetic planet. After a few years he got used to it, but he tried to skip it as much as possible.

"Hey, Zim" Yelled a voice that Zim was accustom to hearing every day; more so then he had wished.
