All right, I decided to take a crack at writing an Invader ZIM AU! The reason I did this was because the thought just went into my head and now it won't get out! Either way, this is a thing now, and I hope you like it! Enjoy!

Going down through the toilet base, a green alien with blue eye contacts, a black wig, a grey backpack-like machine, and a red shirt with black stripes was coming down, smiling in relief. All in all, he considered his landing on the planet he was going to be a complete success, and blending in... well, he had to admit it wasn't perfect, but he managed to at least fool the... 'hyoo-mans', Zim thought to himself.

Or rather, announced to himself. "The Tallest were wise to choose me. This planet won't know what hit it after I've learned its weaknesses..." Zim blinked a bit and winced. "D'OH, these lenses are all scratchy!"

After recovering from his blinking, as he landed in his seat that had a big screen computer in front of him, he started typing, still thinking that this was pretty... amazing. Not only did the Tallest give him another chance in terms of being part of the invasion, BUT he also got a top secret planet that he had to conquer himself. He couldn't wait to tell the Tallest about his arrival... as he sat down in his chair in the lab that was now being built, he leaned his finger towards the call button... before he stopped.

Should he call the Tallest now and let them know that he had arrived at the assigned 'secret' planet? He wasn't quite sure... he might want to do more research on the planet first.

And thusly, he did. Thanks to some pretty good hacking skills, he managed to get his computer online to the place he was currently living in. Zim squinted at the name of the town and was about to pronounce it... but figured it wasn't important. The more important thing to do was try to find places where he could research more about humans, how they react to an invasion, and what they could do.

Of course, he announced it to himself. "Now, to find the best possible way of "learning" about this sad, filthy little planet. The more we know, the sooner we can conquer this spinning ball of... filthy, er-er-er, dirt!"

Zim shuddered a bit, frowning as he continued typing, looking for a place to learn. In the end, he found something that was relatable... as Zim clicked on the picture, he looked up and inspected it... a picture of a school building was apparent, or rather... the 'SKOOL' building as Zim raised an eyebrow. But Zim shook his head as he announced, "This looks like a good place to learn."

Zim clicked on the information as he started to read. "Hmmm... interesting... why would they need 'seven' grades?"

Zim smirked as he started looking at the list of grades and started reading through them. As soon as he read about the first through third grades, Zim scoffed. "Beginners. Zim is no beginner!"

Zim smirked as he had his cursor around the seventh grade. "Zim is the smartest, so I should be in the highest grade!"

Zim was about to click on the grade... but paused as he put his hand on his head. "Hmmm... but if I do that, it would probably tip off some people... so maybe I better go lower..."

Zim growled as he was about to go down, then frowned as he moved the cursor back up. "No! Seventh is the best! Nothing lower!"

Zim paused. "On the other hand, better safe than sorry..."

Zim growled. "No! I want to be successful!"

Zim groaned as he held his head. "Oh, what do I choose, what do I choose?"

Zim sighed as he pulled out a coin. "All right, all right... heads, I go to seventh. Tails... I go to sixth grade."

The green alien shut his eyes as he tossed the coin up in the air and watched it go down. Zim raised an eyebrow as he looked at the coin and nodded. "The choice... has been made..."

Meanwhile, in another house in a different neighborhood, probably not too far from where Zim was, inside, a purple haired girl wearing a black dress and a skull necklace was calmly playing her video game as she looked up in confusion.

She looked around, wondering why she had an odd feeling in her heart. Sure, Dib was quiet, but it was to be expected, his 'favorite show' was on. And it wasn't hot... nor was it chilly in the house.

She just couldn't figure out why she was freezing. It was like... the universe had tipped over a little bit. "Dib?"

"What is it, Gaz? I'm in the middle of an interesting episode here!" Dib called.

Gaz opened her mouth... then frowned as she rolled her eyes. "Forget it."

With that said, Gaz just decided to focus on her game, knowing that things would probably tip back to normal in the morning. After all, she was never the social type.

Little did she realize was that she was about to be disturbed or intrigued by a newcomer... pretty soon.

And the first chapter is complete! Yeah, I always wondered what would happen if Zim went in Gaz's grade instead of Dib's? How would the story change? Would it be the same? Who knows? That's why I'm writing it down! What do you guys think of this concept! I'd love to hear your feedback on this! Read and review!
