FYI: This Story is A ZADR AU of The original Invader Zim TV Series that aired on nickelodeon where Zim is actually a well-respected and successful invader, who is loved by his leaders, and his people. He has a good disguise and fits in perfectly with the humans, and befriends Dib, and lives a double life while trying to keep his secret under wraps.

Zim is not short in this AU he is average human height. Also, all characters are aged up for obvious reasons. So just think of invader Zim happening in high school instead of grade school. I wanted to write a story with a smart respected Zim and give my readers a feel for what the series would have been like if Zim wasn't defective, and was actually appreciated for his loyalty, and tireless efforts. I also added a little ZADR twist because who doesn't like ZADR? Also, this is different from my Prince AU series. Zim is just a regular Irken in this story with no royal heritage.

Disclaimers: I do not own Invader Zim

The Wettening Megadoomer of Doom! (Part 1)

(Location: Deep space aboard The Massive)

The Massive and the Irken Armada hovered above the mechanical planet Storagia. Inside of a long, tube-like structure that was the main processing center for delivery orders were hundreds of individual storage compartments, and the Tallest stood on a hover platform looking them. They finally reached on in particular and a beam of light shot out from the bottom of the hover platform to engulf the whole compartment and show them what was inside.

The Megadoomer!

Now to say that the Megadoomer Combat Stealth Mech was an enormous machine of destructive force would be an understatement. With the missile launchers on its "shoulder" region and sides, the hydraulic engines running it's legs and it's large, taloned feet, this was a weapon of mass destruction that laid waste to planets and looked good while doing it.

"I don't like it." Purple spoke freely.

"We didn't build it so you could "like it"." Red snapped. "This one's going to planet Meekrob to help Invader Tenn conquer it!"

"Well I SHOULD like it." Purple remarked, sticking his tongue out.

A Message appears on the digital roster in Red's hands.

"Looks like we have a second order." He told Purple.

"Really?" Purple sounds amazed. "Someone else wants to use this piece of junk? What idiot would want this?"

Red smiled. "Zim."

"Justification?" Purple asked, his brow rose with curiosity.

"It would appear that the traitor Tak is proving to be a bigger handful then he previously suspected. She has almost exposed our existence to the enemy countless of time."

"He needs a Megadoomer for that?" Purple is confused.

"It has a new tracking and autopilot feature." Red explained. "As long as he has a sample of Tak's DNA it will track her down until it's destroyed, or she dies."

Purple looed at the Megadoomer as if for the first time. "I Like it!" He said.

Red rolled his eyes. "You only like it now because Zim wants to use it!" He declared.

"No, I always liked it." Purple lied. "Speaking of Zim when were we going to tell him the big news?"

"Well we got cut off during the last transmission and Zim hasn't bothered to report in since." Red huffed.

"He's busy, you know he gets like this when he's focused." Purple remined him.

"I know, but he's about to be announced as the Taller!" Red whispered softly so none of the drones around them would here.

The Irken Brain Lineage had shared the news with them only days after Zim had arrived too Earth. Every 10 cycles of a Tallest's rule a Taller was chosen, However not many knew how they were chosen. The Computer Brain Lineage would select 3 possible candidates who would called back to Irk for Testing. The 3 in question would have no idea what the Test was about or what it was for, but once the brain finished testing all three it would decide based on the test results.

And 3 months after Zim left for Earth Lineage had announced that Zim was one of the Three Irkens who had been chosen as a candidate for the position as their successor. Both Red and Purple knew this might happen, in fact they were surprised that they did end up going up against Zim when they had been chosen. However, for some reason the brain had not chosen him. Purple argued it was because Zim was still far too short back then, and Red was quick to agree.

Now, don't get them wrong Red and Purple wanted Zim to succeed them, but there was just one problem…Zim didn't! In fact, he was open about the fact with his Tallest, and freely admitted that he could never imagine himself sitting around, doing such a boring job. And this was why Red was so anxious. He had no doubt that Zim would be selected as the best Candidate out of the three and appointed as their Successor.

"He's too reckless." Red argued. "As an invader that's fine, his reputation speaks for itself, but as a Tallest." He whispered. "He can't just disappear for months at a time."

"All the more reason for him to get it out of his system now." Purple reasoned.

They then rose back up to another platform, this time containing DOZENS of defective SIR units who were all going wild. One was wrestling, one LARGE clump was rolling around like a destructive ball of crazy, another was on FIRE, and one actually had DYNAMITE strapped to its chest. Where'd it get the dynamite?!

"Malfunctioning SIR units! Hey! These things are dangerous! Anyone using these could really get hurt!" Purple realized.

"Throw them out the air lock, would you?" Red instructed the drone to his left.

"Yes, my Tallest. The Drone answered.

(Location: Earth)

[Midnight…]

She had never been more frustrated in her whole life!

Tak hissed loudly, when the Dib had told her that the Swollen Eyeball base was at the docks, she had thought finding it would be easy. However, all that she found was one warehouse after another filled with disgusting fish, boats, and supplies. She had even discovered some agents of the enemy who were most likely there to stop her. She managed to dispatch them quickly and locked them all in a closet of one of the Warehouses. She knew she had to be close if they were here, but she still could not find any sign of a secret base.

If she had more sophisticated tech, She would be able to Xray the ground and see if anything was lurking underneath, but atlas all she had was tools of her own invention. Said devices worked well enough, but that were usually made from primitive parts that she found in the human waste dumps. Such old and damaged parts did little to produce reliable instruments.

If she had the support of her people her tech would be just as good as Zim's, or even better if she crafted it herself with reliable parts. Still, she knew the Tallest wouldn't dare speak to her without proof. Afterall, she had no doubt that Zim had already reported her location to them. Feeding them his lies about her being a defective. This of course, would discredited her on the spot. For perhaps the ten thousandth time she wished that Zim was stupid, it would make her life so much easier. However, the more she fought him the more she came to realize that it was Zim's art of deception and brains that had kept the truth about him being a defective hidden for so long.

She shook her head, forcing herself to focus as she began another round of searching. She had to find the hide out if she wanted any chance of convincing the Tallest of Zim's lies. Her pace quicken with this knowledge. She had searched each Warehouse one by one starting from the west side, Each one was numbered, and the further she went the numbers got lower and lower. It's then she realizes she must have started at the end of the count, instead of the beginning. She Shrugged it off, after all it wasn't like it mattered.

She couldn't have been more wrong. For one the other side of the harbor her target laid in plain sight.

Warehouse 13!

(Back with Dib)

He couldn't believe how stupid he was.

Miz had warned him that the enemy could take on any disguise, and yet he was still dense enough to spill secrets to a stranger!

Dib used his night vision binoculars to scope his surrounds; at the moment he was surveilling the docks…ALONE! Yes, he knew this was stupid, and that he had been given strict orders to not go running off and playing hero on his own. Both Zim and Tak had their sights set on him, but he couldn't help but feel responsible. Tak, was so close to finding their headquarters, thankfully he had left out the number of the Warehouse, but with only 348 at the Harbor it wouldn't be long before she came across Warehouse 13.

Dib tensed as he see movement, he zooms in his focus and sees his target! It is Tak, she is alone and heading his way. He watched as she stopped to search each warehouse, she passed one at a time. He pulls out his phone, he knows the wise thing to do would be to call Dark Booty and report his findings, but after the whole Career Day mess, Dib had been given strict orders to stay as far away from any Irken business. So instead he calls Miz.

Yes, he and Miz were still on speaking terms. Dib had meant to follow his sister's advice and stay away from him until he sorted out his feelings for Zim, but it just never worked out that way. And now Dib was beginning to think staying away from Miz was just as impossible for him as staying away from this Irken business.

He dials the number and waits.

(Back with Zim)

At that very moment Zim had just received his package from the Tallest and was examining its contents. GIR was swimming through a large sea of packing peanuts and happily singing as he did so, his doggy disguise on his person. Zim calmly lifted GIR up by his disguise's ears and grinned as he looked the Megadoomer over. "The Megadoomer, GIR! The most powerful stealth robot in the Irken Military." He told GIR, dropping the robot who walked over to the Megadoomer. "Engineered by conquered Vort scientists actually." He revealed.

GIR gasped, his mouth making a perfect "o", and then he hugged the robot's legs. "It's got CHICKEN LEGS! I WUB it already."

Zim blinked, then nodded. "Yesss…chicken legs…" Zim agreed. "It also possesses a new generation distortion cloaking system. You know what that means?"

GIR promptly soared into the air, spazzing out and screaming as his body swirled around. "WAAAUHH-HOOOOO!"

Then he settled back down and shook his head.

"That means it turns invisible!" Zim told him, whacking his fist into his open palm.

"I had no idea!" GIR remarked. Zim hopped onto his head and GIR's jet-feet activated as GIR lifted Zim to the top of the Megadoomer.

"It's a bit much but I will use this to annihilate Tak!" Zim swore as he entered the open cockpit. "I can't WAIT!"

"I'm FLOATIN'." GIR remarked.

Zim began typing the at the controls and opens the data inventory. He sees that the Tallest had a sample of Tak's DNA already in it's data banks. Of course, every Irkens DNA was kept on file for some like Zim's would be used to clone the next generation of Irkens. However, defective DNA like Tak's and Drones where not used for cloning, instead it was kept and studied by Irken scientist. The goal from these studies was to learn why the Irken race kept producing such bad eggs so less would be made in the future. "Excellent!" Zim praised.

Zim then programs the Megadoomer to use said DNA to track down and eliminate Tak, by any means necessary.

"I'm gonna eat these legs!" Gir declared.

"Silence! My victory... begins... NOW" Zim declared as he activated the machines stealth mode before jumping out.

The Megadoomer came to life, Phasing through the wall before turning invisible as it stomped down the street towards tracking it's enemy.

"Did you know it could do that?" Gir asked referring to how the robot just went through the wall like a ghost.

"No." Zim admitted.

Suddenly his cell phone rang.

He picks it up from the table beside him and answers. "Hello?"

"Hey you busy?" Dib asked on the other end.

Zim looked around his now filthy house covered in a sea of package peanuts and sighed. "No why?"

"I may need some back up." He admitted.

Zim's eyes widen. "Dib what are you doing right now?" He asked.

"I'm staking out the Docks for Tak." Dib informed him, confirming his worse fears.

Zim felt a knot form in the pit of his stomach, he had just programed a Megadoomer to take Tak down by any means necessary. If Dib got in the way the machine might mistaken him as an ally of Tak's and seek to destroy him too. "Dib get out of there now!" He warned. "Dark Booty said they'd keep an eye out for Tak."

"But they're not even out here." Dib reported. "I've looked all over the Docks, but I see no one. I think Tak took them out."

This wasn't good. If Tak managed to fid the base before the Megadoomer found her she would have what she needed. All she'd have to do is avoid the machine long enough to report her findings to the Tallest. After that, if they bought her story, they would use the override command from the Massive to power down the Megadoomer, thus sparing her life, and giving her the chance to expose him.

Zim's eyes narrowed. 'Not on my watch.'

"Stay put." He told Dib. "I'm on my way!"

Zim hung up and immediately dialed another number.

There was three rings and then…

"Hello?" Mrs. Bitter said.

"It's me." Zim said firmly. "I need a favor."

For a moment there is silence and then…

"I'm listening…"

(Back with Dib…)

"Roger." Dib answered and hung up only to jump down from his perch on top of Warehouse 13. He knew if he waited Tak may find the place before he got there. He knew Miz would be angry that he was putting himself at risk, but this was for Earth!

He would understand that.

Trying to be as stealthy as possible, Dib turns on the invisibility setting on his jacket and creeps in the direction he saw Tak moments before.

Meanwhile, Tak is growing weary of her search and debates on weather to give up for the night. She had been at this task since Midnight, and already three hours had passed. It would be day light soon, and Tak still needed time to continue working on her base. Ever since moved from London she had been hiding out at Marvin's Weenie factory. The pace was more or less a glorified Hotdog stand, but it didn't start out that way. Once upon a time it had been just a plain hotdog stand, until Tak used Mimi to brain drain the owner; Jeffry Marvin's mind, once drained she reprogramed him to be her own meat slave. After that she had him buy a permit to build her a large dome like structure behind his stand.

The new structure was renamed Delishus Weenie Corporation and to the outside world it appear to be the outcome of another business man expanding his product, but on the inside, it served as her base and it was almost complete. Her hopes was it would be done by the time she called the Tallest.

With that thought fresh on her mind she moves to leave but stops as the ground begins to shake under her feet.

"What the-?"

Suddenly an invisible thing crashed into the Warehouse wall behind her, a huge hole in the shape of a large robot appears.

Her eyes widen, she doesn't need to see it to know what it is. 'That idiot isn't that desperate, is he?'

Apparently, He was, and as the ground begins to shake again Tak realizes why. It's running towards her! She turn and runs knowing that Hiding is no good! This thing would be able to track her to the far reaches of the universe, if need be. She keeps looking over her shoulder as she runs, even though she knows that due to it's invisibility it's no use.

At the moment that she is running out of the Warehouse, Dib rounds the corner and stops as he watches the scene play out before him.

Tak is running, more tripping over herself trying to get away from…nothing?

He feels the ground shaking, it almost sounds like footsteps. Dib pulls out his inferred goggles, in theory he should be able to see anything, including objects that are clocked. Dib stared caring these things around after Tak had chased them through town a while back. He turns them on and his heart drops. A massive robot was chasing Tak towards the dock.

He is floored, he can't believe that what he is seeing. Of course, he knows in an instant who sent it; ZIM! The part he can't believe is that an Irken would go through such extremes to eliminate one of their own, and all because she threaten to take his mission and Expose him? He knew it was serious, but he thought the two were acting silly. The Irkens were supposed to be this superior race, but in the end, they still got hung up on the same primitive issues earthlings did.

Tak, comes to a screeching holt at the end of the dock. The Harbor laid before her and the Megadoomer behind her, she was trap!

Dib is confused, why did she stop? A giant monstrous machine of Death was closing in on her, why didn't she jump into the water?

The answer was simple, Tak already knew that water could destroy her body, but unlike Zim her old and outdated PAK would not help her build immunity to it. If she jumped in it would be like jumping into a pool of acid.

As fear spread across her face it dawned on him.

Dib's eyes widen. 'She's afraid of the water!'

The Megadoomer closes in and Tak realizes she has no choice. It's jump or die! She knows if she jumps, she may suffer some severe burns, but if she can get out before it kills her, she will eventually heal. It's her only chance, but the pending pain makes her hesitate a second longer.

The Megadoomer reaches for her, and she jumps.

Pain engulfs her the moment she touches the water.

Dib watches as she surfaces, screaming in agony. It was almost too gruesome to watch, her visible skin was bubbling, and blistering before him. He could even see steam rolling of off her, he watched as the Megadoomer stopped in it's tracks. Either it wasn't water proof either, or it was simply waiting to see is Tak would die on her own. He wasn't sure he could stomach waiting to see himself.

Then Unexpectedly a bright light shines down on him.

The Megadoomer sees it and begins to retreat, no doubt not wanting to be detected by a possible enemy.

Dib turns to see an army of black cars lined up their high beams on at full blast.

"Dib!" Professor Membrane shouts his name.

Dib turns off his invisibility setting and pulls off the inferred goggles, he knows he's been had. He pulls back on his glasses, confused.

"Are you crazy!" Annabel is just as crossed as her husband. "You could have been hurt."

Gaz and Peg also get out of the car.

"You idiot, we agreed no more getting Involved." Gaz reminded him.

"No, you guys agreed." Reminding them. After Career Day, Mrs. Bitters had given the order all Junior Agent were to stay out of the this. Of course, the only junior agents were Miz, Gaz, Peg and Himself.

"You just don't get it do you?" Peg screamed. "Every time we've faced these guys we've almost died! Every time Dib! Is that what you want? Do you want to die?"

"How did you guys even know I was here?" Dib questioned.

"I told them."

Dib watched in shock as Miz stepped out of the car.

Zim slammed the door as he went. He knew Dib would be furious with him for doing this, but it was for the child's own good. If he had been detected by the Megadoomer he would have died just now, luckily, they had made it in time. Next time, however, they might not be as lucky.

"You sold me out!?" Dib yelled at him.

"Dibson car now!" Professor Membrane ordered!

Dib dragged his feet to the car, his gaze never leaving his boyfriend's. Miz grabbed his arm as he walked pass, stopping him.

"I know you're angry, but I did this because I care." Zim said. The fact that the words were true no longer surprised him. He did care for this human, he wasn't sure if it were love or if Irkens could even love, but he knew he felt something.

Dib shrugged him off saying nothing, He was too angry to talk to him right now.

Zim doesn't let it bother him, he's been with Dib long enough now to know that once his temper cools, he'll realize how stupid he was being, and forgive him.

"Thank you for calling." Mrs. Bitters says as everyone else loads back up into their vehicles.

"For the time being we are in agreement." Zim assures her. "Tracking down Tak with that thing around…"

"Can't you simply disarm it?" Mrs. Bitters asked.

Zim shook his head. "Only the Massive can override it." He answered honestly, after all she gained nothing from knowing said knowledge. "This is to keep the target from overriding the commands and saving their own skin, or worse; turning it against me."

Mrs. Bitters nodded. "I wished you would have thought twice." She admitted.

"I already tried to kill her once 138 Years ago." Zim admitted. "I failed, this time I am leaving nothing to chance."

"You know he'll try to go out on his own again." Mrs. Bitters said the obvious.

"Yes, I know." Zim agreed. "I'll handle it."

Meanwhile, Tak uses the confusion to swim to the nearest shoreline before ducking behind small building. "Mimi." She whispered in her comm device. "Pick up."

The three words barely get out before she passes out, dead to the world!
