Disclaimer: I don't own Invader Zim. I'm pretty sure most fanfic-writers don't.

"IT'S FINISHED!" Zim yelled, raising his arms triumphantly. A giant mass of deformed machinery lay before him in the lab.
"Actually, Zim, it's rather far from done. The complexity of the project has enabled-"
"I'M AMAZING! Having built an ENTIRE time machine in just 2 DAYS!" Zim said, cutting the computer off without a second thought. He sat down and started sucking on a can of soda, ignoring the fact that the computer's mechanical arms were still flying across the machine.
"You know, Zim." the computer said, still working on the massive invention. "You already had a time machine, so I don't understand why..."
"THAT was a space-time object replacement device! It couldn't handle even the SIMPLEST hunter-destroyer machine. THIS INGENIOUS device can actually BRING A PERSON BACK IN TIME!" Zim explained, turning his attention away from the 'completed' project.
"When it's finished, I will travel to the even MORE PRIMITIVE years of Earth, and...mess stuff up...or something." Zim continued, as the computer frantically plugged different parts together.
"And people think I talk to myself!"
Zim's antennae perked up. "COMPUTER! Find the Dib!" he barked, returning to his drink.
A robot arm reached up towards the cealing, where Dib clung upside down, a camera in his hand. He started taking pictures as quickly as he could while dodging the computer.
"When I send these pictures to Mysterious Mysteries, everyone will believe that you're an alien!" he said, pausing to photograph Zim with the machine.
In a second, he was on the floor, having accidentally let go of the cealing with his other hand.
"FOOLISH DIB-BEAST!" Zim yelled, raising himself on his spider legs. He knocked the camera out of his hands. They watched it land near the now-active time machine.
They both dived for the camera, and knocked each other into the swirling vortex in front of the partially completed machine.

Dib landed face-first in a patch of redish dirt. He brought a hand up to his head as he looked around. His camera lay in front of him, miraculously still intact. He picked it up, then stopped.
All around him, he saw Irkens. Thousands and thousands, going through their daily life.
He heard a scream and turned just in time to see Zim land on his hands, his spider legs back in his PAK.
After a few moments of random screaming at each other, Zim realized many of the Irkens were staring at him. They were dressed in rather simplified versions of Zim's Invader clothes, and none of them had PAKs on.
"EH! WHAT IS THIS!" he yelled, looking around at his beloved homeland. There were tall Irkens holding hands with smeets, like they were parent and child.
"Pre-PAK Irk!" he murmured, just loud enough for Dib to hear.
