Alright, I was inspired to do this story thanks to a certain crossover I read (Literally the only other crossover of Invader Zim and PowerPuff Girls Z around at the time of this writing) and I just want to say it made perfect sense for this kind of story to exist, that they should be in the same universe.

So, without further ado, enjoy the reading!

"... And that accursed Dib-Filth managed to foil my plans once again, using some kind of strange radiation-emitting device! The infected burrito was no longer cold but instead heated with the infection gone!" A rather familiar Irken known to masses as Zim continued to yell into the monitor within his underground base. "After hours of researching, I have discovered this destructive device to be called a 'Microwave'!"

"Interesting, Zim..." A voice drawled through the speakers, coming from one of the two tall Irkens that ruled over the Irken Empire, known to their constituents as 'The Almighty Tallests'. The one with red eyes and armor continued to speak. "What do they do with this 'Microwave', and is it a common appliance?"

"Yes, my Tallest!" Zim stood straight before continuing. "The humans use these radiation boxes to heat their food, sir."

"Woah woah woah, they use Radiation to heat their food?!" The purple tallest known as 'Purple' paused from shoving more donuts in his face to feign shock. "What kind of species actually eats toxic products?!"

Just as Zim was about to answer that, a loud smack could be heard above him. Looking up in alarm, he and the Tallests saw his ceiling crumple before BOOM! Gir, his ever faithful and goofy robot, fell flat through the ceiling from the main floor whilst grappling a floating tiny moose known as 'Mini-Moose', engineered by Zim to house one of the most powerful weapons in the universe. "GIR! WHAT ARE YOU DOING?!" Zim screeched before looking at the monitor with embarassment.

"Look Zim, you obviously have your hands full so I am just gonna have to let you go..-" Red reached for the end-call button before Zim called out.

"No wait! Please my Tallest, I require assistance! I cannot fully conquer this planet if my minion continues to malfunction, especially with the Dib-Beast consistently foiling my plans! Zim requires another SIR unit!" Zim was on his knees, begging his leaders. The Tallests looked at each other before speaking.

"Listen Zim," Purple rubbed his forehead before continuing. "You do realize that you're the only one who still hasn't conquered the planet for Operation Impending Doom II, right?"

"W-well..." Zim stammered before being interrupted.

"Not only that, but the Invaders were on substantially more dangerous planets than your 'Earth'." Red pointed out, to which Zim held out his hand.

"Not true my Tallest! This planet has water! I have forgotten to mention..." Zim laughed nervously while twiddling his fingers, while Red and Purple looked at each other with confusion.

"What is water, Zim?" Red asked, raising an eyebrow.

"H2O compund, my Tallest!" Zim answered, while both Tallests rubbed their faces in thought.

"That's a rare compound Zim. While it is dangerous, A few drops of it on a planet shouldn't warrant-"

"It's everywhere my Tallest!" Zim screamed, his eyes wide with fright at the thought. "This planet is 70% water!"

The jaws of the Tallest dropped simultaneously, before they looked at each other before looking back at Zim. "Zim, just a moment." The Monitor turned into a purple screen with the words 'Please Remain on Hold for the next available Tallest.'

Aboard the Massive, the largest battleship in the universe, the Irkens watched their fearless leaders rant and wave their arms frantically at each other.

"Okay Red what do we do?!" Purple grabbed his fellow Tallest's shoulders and shook him about. "We could barely contain a pool of water without letting any enemies get near it, and yet there is a WHOLE PLANET of it?!"

"Calm down Pur." Red grabbed his gauntlets and put his hands down forcibly. "We have the most advanced map of the universe, and even we didn't see this planet until Zim happened around it. It's a safe bet that no one knows of it's existence yet, but we have to be careful. If our enemies learn of it's existence..."

Purple nodded. "We would have a real war on our hands. So what do we do?" He seemed to calm slightly.

"We continue business as usual, but we cannot allow any suspicion to come to this planet. Our shipping facilities are Vort, along with other conquered worlds. The alien races that make and ship our packages would know something was up and investigate Earth. So we cannot approve of sending Zim anything, however he needs to conquer this planet."

"But.. HE'S ZIM! He isn't even a real invader!" Purple yelled out before Red's hand clamped his mouth shut.

"I know that, but I've got a plan. He's gotten close several times apparently. Maybe he needs a simple suggestion..." Red felt a light bulb go off in his head before pointing to the technician. "TURN THE TV BACK ON!"

Zim waited patiently, his eyes unblinking as he watched the TV go static and then back showing his almighty leaders.

"Alright Zim." Red crossed his arms and narrowed his eyes. "We cannot send anything, as we cannot draw attention to the Earth of international security. Though, I do have another suggestion."

"What would that be, my Tallest?"

"Move." Red continued. "Relocate to a different part of the planet and re-establish yourself, invader. A place far away in the Earth where there is no other human like this 'Dib-Beast' you constantly refer to. Restart the mission from scratch. Do I make myself clear?"

"But my Tallest, all the research-"

"DO I MAKE MYSELF CLEAR, ZIM?!" Red bellowed in rage, Zim wisely shutting up and nodding. "Good. Sign off." At that, the signal cut off and the transmission ended.

"What's going on, Master?" Gir sat up and looked at Zim innocently with his cyan eyes, earning a stare from Zim.

"Pack up, Gir. We are leaving. COMPUTER!" Zim shouted at the ceiling.

"Whaaaat?" The Compputer answered lazily, not wanting to be bothered.

"Bring out a hologram of the Earth. We must find a destination! The destination! Bring me the Destinations!" Zim was repeating himself, going mad as the hologram pulled up.

Lifting up Gir by the head, he threw the tiny robot at the hologram. Upon contact, the area hit glowed red.

"The City of Townsville, sir." The computer automatically generated the name of the town.

"That is where we will go!" Zim cackled to himself before it erupted into full-blown laughter. "MWAHAHAHAHAHA!"

It was in the middle of the night when Zim flew above his base within his Voot cruiser, inside with him were his faithful companions GIR and Minimoose. Taking a deep breath, he took out a large button and held it out. "So long, base! You have served your master well." At the click, the base suddenly imploded on itself, the wires contracting and contorting within each other before going off in a tiny explosion, unnoticeable to any of the neighbors. With that, Zim took off towards Townsville, his Irken GPS guiding him as he and Minimoose held conversation.

"Eep!"

"I have to disagree with you there, Donuts are far superior to muffins."

"Eeep!"

"You can dunk a donut in a beverage, unlike a muffin. They fall apart!"

"Eep!"

"Yes, I know the hole in it is bothersome, but take it up with the creator, not with me! A hole in the donut just means less Donut to enjoy."

"I like waffles!" GIR giggled and join in on the conversation, to which Zim chose to just nod.

"Yes GIR. Yes you do."

"Sir, we have arrived at the destination." The computer spoke through his ship.

"Excellent, bring us down!" Zim grinned ecstatically as the neared a small patch of empty land. "There sure are tall buildings here... Computer!"

"Whaaat?"

"Make me a base that would be of good fit for the area!"

"Oh, you actually want me to design something?!" The computer sounded... thrilled? At the concept. "I finally get to do something useful! Stand back!"

Once the Voot landed on the ground and Zim got off, the computer to work on the house. Zim's eyes went wide as he saw what was being built.

Three story house nestled in deeply between two other houses, though this one had a large green Z on the front. The usual gnomes were there, along with a Domo (Google it, these things are amazing). The door opened up, and Zim walked in. Immediately a fence was put around the front and back of the home, along with a sign "Beware of the Dog" at the front.

Inside, the house was fairly similar to that of an upper-echelon style home, with multiple rooms and bathrooms. "Computer! Why is the inside of the base so extravagant?!" Zim called out with annoyance.

"In case visitors come in, you need to be convincing that you are Human." The computer explained as it got to work on the main part of the base, which was underground. "Rest of the fixtures should be complete by tomorrow morning. There is a School nearby. Would you like to register?"

"Yes, register me computer! Without the Dib around, I can finally use my invader prowess at full potential to conquer this planet! Oh, the conquering I will do..."

In a different area of Townsville, three teenage girls were gossiping back and forth. Actually, just two were gossiping, while the third kept hitting her head in annoyance.

"So Jack tried to get with Naomi but he ended up hurting Nikki doing that..."

"Nikki wasn't even with Jack but she is all heartbroken because she cares about him..."

"I thought Naomi was going to yes for sure though..."

"She didn't, she told Jack no and then her ex showed up!"

"No way!"

"Yes way! There was going to be a showdown until the principle came and said-"

"OH GOD CAN YOU BOTH SHUT UP!" The one banging her head stopped and glared at the other two, who were busy glaring back at her. "It's bad enough I have to hear this at school, but at home too?!"

"You know Kaoru, it wouldn't hurt you to just live a little. There's a life outside sports." The red hair girl spoke to the green-eyed one, named Kaoru.

"You're saying this, yet you speak for hours on end about other people's lives Momoko!" Kaoru shot back at the red-head named Momoko. It was then that the blonde stepped between them.

"Girls, calm down. I know it's been a long day, but it's a school night. We need our beauty sleep."

"You're the one keeping us awake with your gossip Miyako." Kaoru sighed and rubbed her forehead before laying back down in bed. Miyako and Momoko followed suit and laid on their own beds. Kaoru stayed there for a few minutes, unable to sleep before sitting back up.

"Look, sorry girls. I'm a just a little nervous."

"You, nervous?" Miyako sat up and looked at Kaoru.

"We are finally seniors at school, and we graduate in a year. I just can't wait to be done is all."

"I can see where you're coming from." Momoko spoke up. "But you know, we waited a long time for this. Soon we will be out in the real world and doing our own thing. Fighting monsters and saving the city, it's fun but soon we are going to have to grow up, you know?"

"Yeah... I guess.." Kaoru sighed and laid back down. "Night girls."

"Goodnight!"

"Nighty!"
