Gaz: avatarjk137 does not own Invader Zim, or any characters in this fanfic (except Kloof and Reapir.) Now return my Gamethrall to me, or I'll drop you into the deepest circle of hell where your very flesh BURNS with-

Chapter 4

Rooftop Showdown

Grinning, Zim grabbed his latest invention, designed by him over the course of two months. It was a very important invention, and although it wouldn't conquer Earth, it would make any plans to do so that much easier. "GIR! Minimoose! Come to ZIIMM!" Zim's robotic assistants obediently rode down the elevator into Zim's laboratory. Gir's head was attached to his small, metal body upside-down. This caused Zim to raise the Irken equivalent of an eyebrow, but he continued anyway. "Minimoose! Your new weapon is operational, yes?"

"Squeek!" Minimoose squeaked affirmatively in reply.

"Good!" Zim hissed. "Now Gir, this new invention pertains to you. It is a temporary behavior stabilizer, and-"

"WOOOHOO!" Gir interrupted. "I drank some gasoline!" Gir belched, a small flame escaping from his mouth.

"GIR! This invention will lock you into Duty Mode for exactly half of an EARTH hour! Long enough to carry out my plan, but short enough that you WON'T question my authorityyy!" Zim slapped Gir's head, causing it to rotate back to its original position, then popped open the top of the giggling robot's head and installed the stabilizer device.

Gir immediately switched to duty mode. "Gir is ready to serve, master! Use me as a tool of destruction! Raugh!" he screamed enthusiastically.

"Excellent, Gir!" Zim exulted. "Now we are ready to bring the Dib-fool down for good!" Just then a thought popped into his mind. Power #13, active. Zim remembered from the file that Power #13 allowed him to take others on his journeys through shadow. He grinned again. "Just the power I needed for the missiAUURRGGH!" Electricity coursed through his body again, and he staggered. "It is okay, Zim is alright." He grabbed Minimoose and Gir, and pulled them into his own shadow. He then dove in himself, laughing maniacally.

Gaz stared out her bedroom window. Zim and his robot sidekicks had just materialized on the front lawn, inside the electric barrier. Gaz sighed. They're here to attack my stupid brother. They don't know that Kloof's still here. Still, I might be needed. But why should I always save my stupid brother from that stupid alien? A realization struck me. Hey, he owes me a large pizza. That's as good a reason as any to keep him alive. She took the fuzzy mittens off of her pink pajamas. The mittens restrict finger movement, and I'll need finger movement for this, she thought, reaching for her fully charged Gamethrall.
Zim was climbing the stairs to Dib's bedroom, his spider-legs extended. "HA!" He shouted, knocking the door open. "Dib-monkey isn't in here…" He looked around. The computer had been left on, and the bedroom was indeed empty.

"Master!" Gir spoke up. "Multiple life forms on the roof! Also detecting multiple mechanical signals!"

"Dib must be up there!" Zim backed out of Dib's room, and ran up the stairs to the roof, not thinking about what the other signals were.

He got his answer. As he emerged onto the roof, Kloof was starting his spaceship and beginning to climb inside. "Oh, hi, Zim! Listen, I'm just leaving, so I'll leave you alone with Dib. I have to go do this thing."

"Kloof! You go NOWHERE, betrayer! GIR! Stop Kloof from leaving!" Zim shrieked, his face changing from surprise to deep-seated hatred in less than a second.

"Yes, master! Urghh! EEYAUGH!" Gir leapt into a flying tackle and smashed the very surprised rebel Irken into the cabin of his gunship.

"Zim?" Dib asked. "You don't look too good. Is that upgrade killing you or what?"

It was true: Zim's face was crisscrossed with electrical burns, and his eyes were opened only halfway, like he was only semi-conscious. "I'm fine! I've never been better!" Zim lied hastily. "Now, Minimoose, USE your new weapon on the Dib-worm!"

Minimoose squeaked and began charging a pinkish laser. When Dib dodged the beam at the last second, it dissipated harmlessly on the roof, tiny pink orbs ricocheting from the impact and disappearing. "What kind of beam was that? It didn't even leave a mark on the roof." He turned to Zim. "It's a stupid weapon, Zim!"

"Is it?" Zim asked in reply. "Or is it a coma ray specifically tuned to make Earth creatures permanently comatose?"

"Oh, that isn't stupid," Dib admitted. He then realized that Minimoose was charging another blast, and ran downstairs, screaming. Minimoose followed, squeaking and taking potshots.

Zim noticed the Squidge gunship beginning to take off. "Pits of doodie! Kloof must be too much for Gir, even in duty mode! I have to help him and DESTROY that betrayer!" He tried to dive into his own shadow… and felt his head hit hard metal. "What? Have I lost my power? And WHY is the roof all metal?" Zim's 'shadow' then opened its eyes, and grabbed Zim's antennae with its hands. "Nnooo!" Zim was hurled off of the roof, and Reapir followed, zipping behind Zim and slamming him to the ground. Zim kicked Reapir off of him, and leaped to his feet. "What are you? Why do you challenge ZIIIIMM!"

Reapir began playing a prerecorded message. "Hello, I am the Resisty Engineered Armed Prototype Information Retrieval Unit, or Reapir Unit for short. I am the next generation of SIR unit, designed by The Resisty to fight the Irken Empire. I am undefeatable in close combat, and hope we can be best friends." It then dashed forward, and punched Zim in the face, knocking him back to the ground.

"Alright," Zim said angrily, getting up, "Angering ZIM will be your LAST mistake. I am ZIMMM!"
