On the Massive, the Tallest looked down at a certain Irken. He was short, about Zim's height, with the same eyes, but this Irken was different. His skin was slightly darker green, he had a vicious gleam in his eyes, and his antennae were completely straight. Instead of a standard uniform, he wore a cyber-suit exoskeleton. It was colored deep red, and black on the arms and legs. His PAK was also black, with dark red spots.

"You have done well, Zak" said Red, "You have overcome every test, every trial, everything that has been thrown at you."

"Yes," said Purple, "So far it seems that our project was a success. But we have one last test for you."

The Irken, Zak, looked up at the Tallest and grinned evilly. "Just tell me what to do."

"You know about Zim, right?" asked Red. Upon seeing Zak nod, he continued. "We sent Zim off to the far reaches of the galaxy to get him out of the way. But he still bothers us constantly."

Purple nodded. "We want you to go to Earth, find Zim, and beat some sense into him. Train him, whip him into shape. If you can make Zim competent, then the project will be a complete success."

Zak grinned again. "Where is he?"

A few hours later, Zak was in his personal ship, heading toward Earth. Zak was an Invader, but not just any Invader. At a young age, Zak had been chosen for the so-called "Perfect Invader" Project. This was a top-secret project headed by the Tallest themselves. At a young age, Zak had been fitted with all sorts of machinery, including having his skin and organs partially fused with machinery, multiple optical enhancement lenses, weapons integrated into his cyber-exoskeleton, and more. He had been put through superior elite training and passed every test with ease. The Tallest had thrown several more challenges his way, but he had overcome them all. Zak had not yet been listed as an official Invader, since the Tallest had decided to give him this one last test. Zak hit the button to open the warp drive that would bring him to Earth. As he entered the wormhole, he chuckled to himself.
